Description

Connector assembly, first connector, second connector, device module, and electronic device

Technical Field

The embodiments of the present application relate to the field of electrical connectors, and in particular, to a connector assembly, a first connector, a second connector, a device module, and an electronic device.

Background Art

In order to meet the requirements of good assembly and maintainability of electronic devices such as mobile phones, tablet computers, and laptops, modular design is usually adopted. Taking the power supply battery as an example, the modular power supply battery is connected to other motherboards or modules through a BTB (Board-to-board) connector.

A typical BTB connector is composed of three parts: metal terminals, protective armor, and plastic shell, which are integrated into one body. The metal terminals include power terminals and signal terminals, where the signal terminal is located in the middle of the connector body, and the positive and negative power terminals are symmetrically arranged at both ends of the BTB connector body relative to the signal terminal. Based on the structural configuration in which the positive and negative terminals are symmetrically distributed at both ends of the connector body, during maintenance and discharge, if the male and female heads of the BTB connector are rotated 180 degrees and engaged, there is a risk of short-circuiting and hot melting of the positive and negative terminals; in addition, in the case of assembly deviation, there is a risk of short-circuiting and sparking of the positive and negative terminals, posing a safety hazard.

Summary of the invention

The embodiments of the present application provide a connector assembly, a first connector, a second connector, a device module, and an electronic device, which can effectively avoid the risk of short-circuiting the positive and negative poles, and provide good technical guarantees for the reliability of use in different application scenarios.

A first aspect of an embodiment of the present application provides a first connector, comprising a first body and power terminals and signal terminals arranged on the first body, the power terminals comprising a group of first pole terminals and two groups of second pole terminals; wherein the first pole terminal is arranged in the middle position of the first body, and the first pole terminal comprises a contact portion which is rotationally symmetrically arranged; the two groups of second pole terminals are respectively arranged at two ends of the first body, and the contact portion of the second pole terminal at one end is rotationally symmetrically arranged relative to the contact portion of the second pole terminal at the other end; the signal terminals comprise a first group of signal terminals and a second group of signal terminals, a first group of signal terminals is arranged between the first pole terminal and a group of second pole terminals, a second group of signal terminals is arranged between the first pole terminal and the other group of second pole terminals, and the contact portion of the first group of first pole terminals is rotationally symmetrically arranged relative to the contact portion of the second group of signal terminals; wherein the contact portion of the first pole terminal, the contact portion of the second pole terminal and the contact portion of the signal terminal can be respectively arranged in 180° rotational symmetry, and the rotational symmetry axes coincide. With such a configuration, the assembly and mating between the first connector and the mating connector (second connector) are not restricted by the assembly direction. When the two are mated in the 0° direction or the 180° direction, the power terminal and the signal terminal can be effectively connected, which can effectively avoid the possibility of short-circuiting the positive and negative terminals. At the same time, a signal terminal is arranged between the first terminal and the second terminal, and the physical distance between the two is relatively long, which can further reduce the risk of short-circuiting. Taking the application in battery modules as an example, during maintenance and discharge, the situation of short-circuiting and hot melting caused by the positive and negative terminals can be completely avoided. In addition, in the case of assembly deviation, safety issues caused by short-circuiting and sparking of the positive and negative terminals can be avoided.

At the same time, based on the structural characteristics of the rotationally symmetrical arrangement of the contact parts of each terminal, there is no need to consider the anti-misinstallation structure or process when assembling the first connector or the second connector with the corresponding device on the production line. On the basis of reasonably controlling the manufacturing process cost, the production line assembly efficiency can be further improved.

Exemplarily, the first pole terminal may be a positive pole terminal, and the corresponding second pole terminal may be a negative pole terminal; or, the first pole terminal may be a negative pole terminal, and the corresponding second pole terminal may be a positive pole terminal.

Based on the first aspect, the embodiment of the present application also provides a first implementation manner of the first aspect: the first body includes a top surface and a shielding surface, the top surface is provided with an opening, the shielding surface extends downward from the opening of the top surface, and forms an inner recessed accommodating portion in which the terminal of the mating connector can be placed; the shielding surface includes groove portions respectively opened corresponding to the contact portion of the first terminal and the contact portion of the signal terminal, the contact portion of the first terminal and the contact portion of the signal terminal are respectively embedded in the corresponding groove portions to reduce the exposed area of the two, and the contact portion contact of the first terminal and the contact portion contact of the signal terminal respectively protrude from the shielding surface through the corresponding groove portions, that is, extend into the inner recessed accommodating portion, to achieve reliable electrical connection and signal connection with the mating connector. In this way, this solution embeds the main body of the first terminal and the signal terminal inside the first body, and only the contact part is exposed in the concave accommodating part. Based on the structure, a reasonable separation between the terminals is constructed, which can reduce the possibility of short-circuit contact; in addition, in the application scenario where the first connector and the battery are integrated into a modular device and the second terminal is the negative terminal, during the assembly and insertion process, the grounded negative terminal is turned on first, and then the positive terminal is turned on, which can avoid the occurrence of assembly sparks. At the same time, during the mutual mating and plugging process, the shielding surface is used as the main plugging and pulling mating surface, which can further avoid plugging and pulling pin collapse.

Based on the first implementation of the first aspect, the embodiment of the present application also provides a second implementation of the first aspect: the second terminal includes a first body surface, and also includes a second body surface or two third body surfaces connected to the first body surface; the first body surface is covered on the top surface of the first body at the end, the second body surface extends downward from the first body surface and covers the end wall of the first body at the end, and the two third body surfaces extend downward from both sides of the first body surface and cover the side walls of the first body at the end. In other words, the negative terminal can be covered on the two ends of the corresponding first body, and has the function of protecting the hardware, which can increase the strength of the connector end and effectively avoid end insertion loss.

In practical applications, the first body surfaces of the two negative terminals may be flush with the top surface of the first body therebetween; for example, but not limited to, they may be integrally formed with the first body using an injection molding process, or may be independently processed and then assembled and fixed.

Based on the second implementation of the first aspect, the embodiment of the present application also provides a third implementation of the first aspect: the second pole terminal also includes a guide portion, which extends downward from the inner edge of the first body surface to the concave accommodating portion, and is adapted to fit with the shielding surface on the corresponding side, so as to provide a good guiding effect when the mating connectors are assembled and engaged, so that the mating connectors can be adjusted and aligned; at the same time, the guide portion formed based on the downward extension of the inner edge can further increase the strength of the connector end.

Exemplarily, the number of the guide portions may be three, and they are respectively adapted to fit with the end surface and two side surfaces of the shielding surface on the corresponding side.

Based on the first embodiment of the first aspect, or the second embodiment of the first aspect, or the third embodiment of the first aspect, the embodiment of the present application further provides a fourth embodiment of the first aspect: the top surface opening of the first body includes at least one first opening and at least two second openings arranged at intervals, the shielding surface includes a first shielding surface extending downward from the first opening to form a first concave accommodating portion that can be placed in the first terminal on the mating connector side, and the contact of the first terminal protrudes from the first shielding surface via the groove on the first shielding surface; the shielding surface also includes a second shielding surface extending downward from the second opening to form a second concave accommodating portion that can be placed in the signal terminal on the mating connector side, and the contact of the signal terminal protrudes from the second shielding surface via the groove on the second shielding surface. Thus, the first terminal and the signal terminal are separated and shielded separately. In other words, the possibility of connecting the positive and negative poles can be further reduced through structural subdivision.

In practical applications, the top surface of the first body may have one opening, and the grooves provided on the shielding surface include a first groove and a second groove, which are respectively arranged corresponding to the contact portion of the first terminal and the contact portion of the signal terminal.

Based on the first aspect, or the first embodiment of the first aspect, or the second embodiment of the first aspect, or the third embodiment of the first aspect, or the fourth embodiment of the first aspect, the embodiment of the present application also provides a fifth embodiment of the first aspect: at least one of the second body surface of the end wall of the second terminal covering the first body and the two third body surfaces of the side wall of the second terminal covering the first body is provided with a pit or a snap-fitting protrusion; the pit or the snap-fitting protrusion is used to snap-fit with the mating connector, and is arranged in 180° rotational symmetry. During the assembly process, the initial metal extrusion force is large and deformed. When the corresponding snap-fitting protrusion is aligned with the pit, the extrusion force is reduced and the deformation is released, and a good plug-in and pull-out feel can be fed back.

Based on the first aspect, or the first embodiment of the first aspect, or the second embodiment of the first aspect, or the third embodiment of the first aspect, or the fourth embodiment of the first aspect, or the fifth embodiment of the first aspect, the embodiment of the present application further provides a sixth embodiment of the first aspect: the first terminal comprises a fixed portion and a contact portion formed by bending and extending in sequence, the contact portion comprises a first body segment and a second body segment spaced and arranged oppositely to form a double-contact structure, the first body segment is connected to the fixed portion of the first terminal, and the first body segment is provided with a first contact, and the second body segment is provided with a second contact, that is, the second body segment is an elastic arm, which can elastically contact the fixed terminal or elastic terminal on the side of the mating connector, and can ensure the reliability of electrical contact. At the same time, the elastic terminal can be retracted into the interior of the first body to the greatest extent to reduce the risk of short circuit.

Furthermore, the width dimension of the second body segment of the first terminal is smaller than the width dimension of the first body segment. With such a configuration, the groove portion on the first shielding surface adapted to the second body segment can be configured to be relatively narrow in size, thereby reducing the possibility of short circuit. In addition, for the second contact on the elastic arm side, its contact dimension with the mating side terminal is also relatively small. Compared with the terminal with the equal cross-sectional structure, the contact dimension of the second contact in this solution is smaller, and the deformation force of the second body segment as an elastic arm is smaller, and the contact impedance is correspondingly smaller, thereby obtaining a large flow capacity.

Furthermore, at least two signal terminals are arranged on the same end side of the first terminal, and at least two signal terminals are configured as follows: the first contact and the second contact of one part of the signal terminals are arranged opposite to the first contact and the second contact of the other part of the signal terminals in the width direction. That is to say, the first body segment of one part and the second body segment of the other part are located on the same side in the width direction; at the same time, the second body segment of one part and the first body segment of the other part are also located on the same side in the width direction. In this way, the at least two signal terminals arranged on the same end side of the first terminal have opposite directions of the forces on the mating connector side formed after the elastic arms are deformed. Based on the structural characteristics of the same force magnitude, the deflection torque will not be generated or can be effectively reduced, and the mating connector will avoid the tendency to rotate, so that the mating terminals can maintain a reliable and stable connection relationship.

DETAILED DESCRIPTION

The embodiment of the present application provides a connector assembly implementation solution that can effectively avoid the risk of short circuit caused by incorrect connection of positive and negative poles.

The connector assembly includes a first connector and a second connector that are mutually compatible, and power terminals and signal terminals are fixedly arranged on the insulating bodies of both connectors, wherein the power terminal includes a first pole terminal and a second pole terminal. The "first pole terminal" and the "second pole terminal" are respectively the positive pole terminal and the negative pole terminal for transmitting current, and the signal terminal is used to transmit signals for sampling and anti-counterfeiting identification and other functions. After assembly and mating, the contact parts of the power terminals and the signal terminals on the first connector are respectively adapted to the contact parts of the power terminals and the signal terminals on the second connector to establish a corresponding connection relationship. Based on the assembly and mating relationship of the mutual matching connection, one can be a plug connector and the other can be a socket connector.

In this embodiment, a group of first pole terminals is arranged in the middle of the insulating body of the first connector or the second connector, and the first pole terminal includes a contact portion arranged in 180° rotational symmetry; two groups of second pole terminals are arranged at two ends of the connector insulating body, respectively, and the contact portion on the second pole terminal at one end is arranged in 180° rotational symmetry with respect to the contact portion on the second pole terminal at the other end. The rotational symmetry axis of the contact portion of the first pole terminal coincides with the rotational symmetry axis of the contact portion of the second pole terminal.

Meanwhile, the signal terminals include a first group of signal terminals and a second group of signal terminals, the first group of signal terminals are arranged between the first pole terminal and a group of second pole terminals, the second group of signal terminals are arranged between the first pole terminal and another group of second pole terminals, and the contact portions of the first group of signal terminals are arranged 180° rotationally symmetrically with respect to the contact portions of the second group of signal terminals. The rotational symmetry axis of the contact portions of the signal terminals coincides with the rotational symmetry axis of the contact portions of the power terminals.

Herein, the first-level terminals, second-level terminals and signal terminals in groups refer to corresponding terminals located in the same area. It should be understood that each group of terminals includes one terminal and multiple terminals at the same time.

In this way, the assembly and mating between the first connector and the second connector are not restricted by the assembly direction. When the two are mated in the 0° direction or the 180° direction, effective connection between the power terminal and the signal terminal can be achieved. Compared with the existing solutions, the application of this implementation scheme can completely avoid the possibility of short-circuiting the positive and negative terminals, and can effectively avoid safety hazards such as short-circuiting hot melting or short-circuiting sparks. At the same time, based on the structural characteristics of the 180° rotational symmetry of the terminal contact part, when assembling the first connector or the second connector with the corresponding device on the production line, there is no need to consider the anti-misinstallation structure or process. On the basis of reasonably controlling the manufacturing process cost, the production line assembly efficiency can be further improved.

In order to better understand the technical solution and technical effect of the present application, the following describes a BTB connector as the object of description, and takes the first terminal as the positive terminal and the second terminal as the negative terminal as the basic configuration structure, and describes a specific embodiment in detail in conjunction with the accompanying drawings. Please refer to Figure 1, which is a schematic diagram of a connector assembly provided in an embodiment of the present application.

The connector assembly 100 includes a first connector 10 and a second connector 20 that are compatible with each other. The first connector 10 and the second connector 20 are respectively arranged on two devices to be connected for mutual connection. As shown in FIG1 , along the direction indicated by the arrow in FIG1 (a), the first connector 10 can be inserted and engaged on the second connector 20 to form a connector assembly 100 as shown in FIG1 (b). After the first connector 10 and the second connector 20 are inserted and engaged, electrical connection and signal connection between the two devices to be connected can be achieved. Without loss of generality, the first connector 10 here is a plug connector, and the second connector 20 is a socket connector accordingly, and the first connector 10 and the second connector 20 are in the shape of mutually compatible long strips, and the specific length and width dimensions and proportional relationship can be adaptively adjusted according to the actual product configuration.

In this embodiment, the first connector 10 includes a first body 11, a positive terminal 12, a negative terminal 13 and a signal terminal 14. Please refer to Figures 2 and 3, wherein Figure 2 is a schematic diagram of the overall structure of the first connector shown in Figure 1, and Figure 3 is a top view of the first connector shown in Figure 2. The first connector 10 shown in Figure 2 is formed from the perspective of the plug-in mating side with the mating second connector 20 to clearly illustrate the arrangement relationship between the power terminal and the signal terminal.

As shown in Figures 2 and 3, the positive terminal 12 is arranged in the middle of the first body 11, the two ends of the first body 11 are provided with negative terminals 13, and the signal terminals 14 are respectively arranged on the first body 11 between the positive terminal 12 and the two negative terminals 13. Please also refer to Figure 4, which is an exploded schematic diagram of the assembly of the first connector shown in Figure 2.

Among them, the first body 11 is made of insulating material, including a top surface 111, two end walls 112, two side walls 113 and a bottom surface 114. The two end walls 112 extend downward from both ends of the top surface 111, and the two side walls 113 extend downward from both sides of the top surface 111. The bottom surface 114 is located at a lower position relative to the top surface 111.

A first opening 1111 and a second opening 1112 are disposed on the top surface 111 of the first body 11. As shown in FIG2 and FIG4 , the first body 11 further includes a first shielding surface 115 and a second shielding surface 116.

In the present embodiment, the first shielding surface 115 extends downward from the first opening 1111 and encloses a first recessed accommodating portion in which the positive terminal of the mating connector can be inserted, and the first shielding surface 115 is provided with a groove portion 1151, the positive terminal 12 has a positive contact portion 121, and the positive contact portion 121 is provided with contacts (12111, 12121), the body of the positive contact portion 121 is placed in the corresponding groove portion 1151, and the positive contacts (12111, 12121) protrude from the first shielding surface 115 via the groove portion 1151, that is, located in the first recessed accommodating portion to be connected to the positive terminal on the mating side. The second shielding surface 116 extends downward from the second opening 1112 and encloses a second concave accommodating portion in which the signal terminal of the mating connector can be inserted. The second shielding surface 116 is provided with a groove 1161. The signal terminal 14 has a signal terminal contact portion 141. The signal terminal contact portion 141 is provided with contacts (14111, 14121). The body of the signal terminal contact portion 141 is placed in the corresponding groove 1161, and the signal contacts (14111, 14121) protrude from the second shielding surface 116 via the groove 1161, that is, located in the second concave accommodating portion to be connected with the signal terminal on the mating side.

In other words, the main parts of the positive terminal 12 and the signal terminal 14 are both built into the first body 11, and only the contact parts are exposed in the corresponding concave accommodating parts. Based on the structure, a reasonable separation between the terminals is constructed to effectively avoid the occurrence of short circuits; at the same time, during the mutual plug-in process, the main plug-in mating surface is the corresponding shielding surface, which can further avoid plug-in pin damage.

Specifically, the first shielding surface 115 and the second shielding surface 116 shown in the figure are surrounded along the circumference of the corresponding opening to form a corresponding concave accommodating portion, and together with the top surface 111, a structure with a reinforcing effect is formed, and the overall strength of the first body 11 is improved. In other specific implementations, a shielding surface (not shown in the figure) can also be provided only on the side where the positive contact portion and the signal contact portion are located.

In this embodiment, there are two first openings 1111, which are arranged on the top surface 111 of the first body 11 at intervals along the width direction X, thereby forming two first concave receiving portions. There are four positive terminals 12, which are symmetrically arranged corresponding to the two first concave receiving portions, that is, each first concave receiving portion is configured with two positive terminals 12.

In a specific implementation, the first opening 1111 may be provided as one, and may be provided with one or two positive terminals; in other specific implementations, the first opening 1111 may be provided as four, and may be provided with one or two positive terminals respectively. It is understandable that any configuration is acceptable as long as the contact portion of the positive terminal in the corresponding implementation is provided in a 180° rotationally symmetrical manner.

Please refer to FIG. 5, which is a schematic diagram of a positive terminal provided in an embodiment of the present application. The positive terminal 12 includes a contact portion 121 and a fixing portion 122 formed by sequential bending and extension, the fixing portion 122 is used to be fixed to the first body 11, and the contact portion 121 adapted to the positive terminal on the mating side is generally in a "U" shape to form a double contact. Specifically, the contact portion 121 includes two body segments that are spaced and arranged relatively, wherein the first body segment 1211 is connected to the fixing portion 122, and a first contact 12111 is arranged thereon, and the first contact 12111 is relatively fixed; the second body segment 1212 is an elastic arm, and a second contact 12121 is arranged thereon, which can elastically contact the fixed terminal or elastic terminal on the mating connector side, and can ensure the reliability of electrical contact. At the same time, the elastic terminal can be retracted into the interior of the first body to the greatest extent to reduce the risk of short circuit.

Here, the welding foot 123 of the positive terminal 12 is formed by extending the fixing portion 122, and can be specifically located at the bottom side of the first body 11. Here, the welding foot at the edge of the fixing portion 122 can be designed as a discontinuous wave form to avoid the straight line length being too long to affect the welding strength.

As shown in Figures 2 and 3, corresponding to the sides where the first contact 12111 and the second contact 12121 are located, grooves 1151 are provided on the two oppositely arranged shielding surfaces of the first shielding surface 115, so that the first contact 12111 and the second contact 12121 protrude and are exposed in the corresponding first concave accommodating portion.

As shown in the figure, the contact portions 121 of the four positive terminals 12 are arranged in 180° rotational symmetry, that is, they have a first contact 12111 and a second contact 12121 arranged in rotational symmetry. It can be confirmed that the intermate second connector 20 described in detail below is adaptively configured with a positive terminal contact portion arranged in 180° rotational symmetry, and when assembled and mated in a 0° direction or a 180° direction, an effective connection of the positive terminals between the two can be achieved.

In addition, the four positive terminals 12 in this embodiment are mirror-imaged in the two first recessed accommodating portions, so that after being snapped into engagement with the positive terminals of the mating connector, the forces formed in the width direction can offset each other, based on which the connected positive terminals can maintain a reliable and stable connection state.

As further shown in FIG. 5 , the contact portion 121 of the positive terminal 12 in this solution adopts a non-uniform cross-section flow structure, and the width of the second body segment 1212 is smaller than the width of the first body segment 1211. With this arrangement, the groove 1151 on the first shielding surface 115 adapted to the second body segment 1212 can be configured to be relatively narrow in size, reducing the possibility of short circuit on the positive side. In addition, for the second contact 12121 on the elastic arm side, its contact size with the positive terminal on the mating side is also relatively small. Compared with the positive terminal with an equal cross-section structure, the contact size of the second contact 12121 in this embodiment is smaller, and the deformation force of the second body segment 1212 as an elastic arm is smaller, and the contact impedance is correspondingly smaller, thereby obtaining a large flow capacity.

In this embodiment, there are two second openings 1112, which are arranged on the top surface 111 on both sides of the first opening 1111 at intervals along the length Y direction, thereby forming two second concave receiving portions. There are four signal terminals 14, which are symmetrically arranged corresponding to the two second receiving portions, that is, each second concave receiving portion is configured with two signal terminals 14.

Please refer to Figure 6, which is a schematic diagram of a signal terminal provided in an embodiment of the present application. The signal terminal 14 includes a contact portion 141 and a fixing portion 142 formed by sequential bending and extension, and the fixing portion 142 is used to be fixed to the first body 11, and the contact portion 141 adapted to the signal terminal on the mating side is also roughly in a "U" shape to form a double contact. Specifically, the contact portion 141 includes two body segments arranged opposite to each other, wherein the first body segment 1411 is connected to the fixing portion 142, and a first contact 14111 is arranged thereon, and the first contact 14111 is relatively fixed; the second body segment 1412 is an elastic arm, and a second contact 14121 is arranged thereon.

The soldering foot 143 of the signal terminal 14 is formed by extending the fixing portion 142 , and can be specifically located at a side edge of the bottom surface of the first body 11 .

As shown in Figures 2 and 3, corresponding to the sides where the first contact 14111 and the second contact 14121 are located, grooves 1161 are provided on the two oppositely arranged shielding surfaces of the second shielding surface 116, so that the first contact 14111 and the second contact 14121 protrude and are exposed in the corresponding second concave accommodating portion.

As shown in the figure, the contact portions 141 of the four signal terminals 14 are arranged in 180° rotational symmetry, that is, the first contact 14111 and the second contact 14121 are arranged in rotational symmetry. When assembled and embedded in the 0° direction or the 180° direction, the effective connection of the signal terminals between the two can be achieved. In other specific implementations, the number of signal terminals 14 can be determined according to the functional setting, for example but not limited to, each side is configured with one signal terminal or other multiple terminals arranged at intervals.

In order to prevent the elastic arm of the signal terminal 14 from acting on the mating connector to form a deflection torque and ensure balanced force, the configuration of the two signal terminals 14 configured in each second concave accommodating portion can be further optimized. In this embodiment, for the two signal terminals 14 corresponding to each second concave accommodating portion, the first contact 14111 and the second contact 14121 of the contact portion 141 of the two can be configured in the opposite direction in the width direction. In other words, the first body segment 1411 of one and the second body segment 1412 of the other are located on the same side in the width direction; at the same time, the second body segment 1412 of one and the first body segment 1411 of the other are also located on the same side in the width direction.

In this way, the two signal terminals 14 arranged at each second recessed accommodating portion have opposite directions of force applied to the mating connector side formed after the elastic arms of the two terminals are deformed. Based on the structural characteristics of the same force magnitude, no deflection torque causing the mating connector to rotate will be generated, and the mating terminals can maintain a reliable and stable connection relationship.

In a specific implementation, for other multiple situations where each side is configured as an interval arrangement, the above structural configuration principle can also be applied, and the first body segment of one part and the second body segment of another part are located on the same side in the width direction; at the same time, the second body segment of one part and the first body segment of another part are also located on the same side in the width direction, which can also effectively reduce the deflection torque. Of course, the size of each signal terminal can also be adjusted to avoid the rotation tendency of the mating connector.

It should be noted that the positive terminal 12 and the signal terminal 14 are assembled with the first body 11 in such a way that a socket connected to the top surface can be opened on the bottom surface 114 side of the first body 11, as shown in FIG. 1, the first socket 1141 is used to insert the positive terminal 12, and the second socket 1142 is used to insert the signal terminal 14. The structure is simple and the processability is good. Of course, in other specific implementations, based on the positive terminal 12 and the signal terminal 14, the first body 11 can also be molded by an integral injection molding process to obtain a stable fixed connection relationship.

In this embodiment, the two negative terminals 13 are respectively arranged at the two ends of the first body 11. Based on the basic structural characteristics that the positive terminal is located in the middle of the connector and the two negative terminals 13 are symmetrically arranged at both ends, the inter-matching connectors are assembled and embedded in the 0° direction or 180° direction, and both the positive and negative terminals can be plugged in. As shown in Figures 2, 3 and 4, the negative terminal 13 is coated on the two ends of the corresponding first body 11, and has the function of protecting the hardware, which can increase the strength of the connector end.

Please refer to FIG. 7, which is a schematic diagram of a negative terminal provided in an embodiment of the present application. The negative terminal 13 includes a first body surface 131, a second body surface 132 and two third body surfaces 133 connected to each other, and at least one of the three body surfaces can be used as a contact portion of the negative terminal to provide and form a corresponding negative contact. The first body surface 131 is coated on the top surface 111 of the end, the second body surface 132 extends downward from one end of the first body surface 131 and is coated on the end wall 112 of the end, and the two third body surfaces 133 extend downward from both sides of the first body surface 131 and are coated on the side wall 113 of the end, forming a groove-shaped structure with one end open. Thus, comprehensive protection is formed at both ends of the insertion side of the first connector 10, and assembly buckle damage can be prevented on the basis of satisfying the negative terminal connection function. In addition, based on the end protection capability provided by the negative terminal 13, there is no need to configure protective hardware separately, which can save manufacturing costs at the same time.

The welding foot 135 of the negative terminal 13 can be formed by the lateral extension of the bottom edge of the second body surface 132 and the third body surface 133. The multi-welding foot design has good welding strength. For example, but not limited to, the bottom edge length of the second body surface 132 is relatively long, and two welding feet 135 can be configured; the bottom edge length of the third body surface 133 is relatively short, and one welding foot 135 can be configured. In other specific applications, the configuration of the welding foot 135 is determined according to the product design to be implemented.

In other specific implementations, the actual covering position and covering area of the negative terminal 13 can be determined according to the overall design requirements of different products. For example, but not limited to, the negative terminal only includes the first body surface 131 and the second body surface 132 covering the top surface and the end wall, or only includes the first body surface 131 and the third body surface 133 covering the top surface and the two side walls, which can also increase the strength of the connector end.

In addition, in this embodiment, the first body surface 131 of the two negative terminals 13 can be flush with the top surface 111 of the first body 11 between the two; each positive terminal 12 is located below the top surface 111 and is shielded by the first shielding surface 115. In the application scenario where the first connector 10 and the battery are integrated into a modular device, during the assembly and insertion process, the grounded negative terminal is first turned on, and then the positive terminal is turned on, which can avoid the occurrence of assembly sparks.

In addition, the negative terminal 13 also includes a guide portion 134 extending downward from the inner edge of the first body surface 131. Please refer to Figures 2, 4 and 7. The guide portions 134 are provided in three numbers, and are respectively fitted with the end face and two side faces of the second shielding surface 116 on the corresponding side, so as to provide a good guiding effect when the mating connectors are assembled and engaged, so that the mating connectors can be adjusted and aligned to quickly realize the assembly operation; at the same time, based on the guide portion 134 extending downward from the inner edge, the strength of the connector end can be further increased.

In order to further improve the assembly feel, the second body surface 132 of the negative terminal 13 is provided with a pit 1321 , and the third body surface 133 is provided with a pit 1331 , which can be respectively matched with the protrusions on the mating connector.

The following is a detailed description of a second connector 20 that is mated with the first connector 10. Please refer to Figures 8 and 9, which are schematic diagrams of the second connector formed from different angles, wherein Figure 8 is formed from the angle of the mating plug-in side of the second connector, that is, from the top perspective, and Figure 9 is formed from the bottom perspective of the second connector shown in Figure 8.

In this embodiment, the second connector 20 includes a second body 21, a positive terminal 22, a negative terminal 23 and a signal terminal 24. Corresponding to the power terminal and the signal terminal on the first connector 10, the positive terminal 22 of the second connector 20 is also arranged in the middle of the second body 21, the negative terminal 23 is arranged at intervals at both ends of the second body 21, and the signal terminal 24 is respectively arranged on the second body 21 between the positive terminal 22 and the two negative terminals 23. Please also refer to Figure 10, which is an exploded schematic diagram of the assembly of the second connector shown in Figure 8.

Among them, the second body 21 is made of insulating material, including a bottom surface 211, two end walls 212 and two side walls 213. The two end walls 212 are extended upward from the two ends of the bottom surface 211, and the two side walls 213 are extended upward from the two sides of the bottom surface 211. The bottom surface 211, the two end walls 212 and the two side walls 213 enclose an inner concave space that can accommodate the first connector 10.

In this embodiment, the positive terminal 22 includes a bottom plate 222 and two contact portions 221, the two contact portions 221 are arranged on the bottom plate 222 at intervals along the width direction, and are respectively protruded upward from the bottom plate 222, specifically, a protruding shell structure that can be inserted and adapted to the first inner concave receiving portion on the side of the mating connector. Here, based on the metal plate material, the positive terminal 22 can be formed by an integrated extraction process or a sheet metal bending process to provide stronger reliability.

Here, the welding foot 224 of the positive terminal 22 may be formed by extending the bottom plate 222 , and may be specifically located at a side edge of the bottom surface of the second body 21 .

Please refer to Figures 11 and 12 together, wherein Figure 11 is a top view of the connector assembly 100 shown in Figure 1, and Figure 12 is a schematic diagram of the contact assembly relationship between the positive terminals of the mating connectors formed from the A-A section position in Figure 11.

As shown in the figure, the two contact portions 221 are arranged in 180° rotational symmetry, and have rotationally symmetrical contacts adapted to the positive terminals on the mating connector side. When assembled and mated in the 0° direction or the 180° direction, effective connection between the positive terminals of the two can be achieved.

The positive terminal 22 can be integrally formed with the second body 21 by injection molding, and its bottom plate 222 can be built into the bottom surface 211. As shown in FIG9, the bottom plate 222 of this solution is roughly the same width as the second body 21, and can also be used as an internal reinforcement plate to improve the bottom plate strength of the second body 21. In addition, the positive terminal 22 is also provided with two bent portions 223, which are formed by extending upward from the bottom plate 22 and are spaced apart in the width direction, thereby further enhancing the reliability of the fixed connection between the injection molded components.

In this embodiment, the second body 21 also includes two islands 214 protruding upward from the bottom surface 211, and are respectively arranged in one-to-one correspondence with the two second concave accommodating portions on the mating connector side, and each island 214 is respectively provided with two signal terminals 24. As shown in Figures 8, 9 and 10, the signal terminal 24 includes a contact portion 241 and a fixing portion 242 formed by sequential bending and extension, and the contact portion 241 is in an "n" shape to form a double contact. The two relatively arranged body segments 2411 of the contact portion 241 are respectively located on both sides of the island 214, and a convex contact 24111 is arranged on one of the body segments 2411. Among them, the adjacent body segment 2411 of the convex contact 21111 is concave, which is used to adapt to the first contact 14111 relatively fixed on the mating connector side. During the buckling process, the first contact 14111 is compressed and deformed and rebounds, which can feedback a good plug-in and pull-out feel.

Please refer to FIG. 11 and FIG. 13 , wherein FIG. 13 is a schematic diagram of the contact assembly relationship between the signal terminals of the mating connectors formed at the B-B section position in FIG. 11 .

The fixing portion 242 is provided in two sections, which are respectively extended from the two body sections 2411 of the contact portion 241, and can be designed with double soldering feet, so the soldering strength is good. The signal terminal 24 can be formed into one piece with the second body 21 by injection molding, and the two sections of the fixing portion 242 can be built into the bottom surface 211 and extend laterally from the second body 21 to form soldering feet 243.

As shown in the figure, the contact portion 241 arranged on the two island portions 214 is also arranged in 180° rotational symmetry, and has rotationally symmetrically arranged contacts (14121, 14111) adapted to the signal terminals on the mating connector side. When assembled and mated in the 0° direction or the 180° direction, effective connection between the signal terminals of the first connector and the second connector can be achieved.

In this embodiment, the two negative terminals 23 are respectively arranged at the two ends of the second body 21 and are arranged adjacent to the signal terminal 24. As shown in Figures 8 and 10, the negative terminal 23 includes a fixed portion 232 and two contact portions 231. The two contact portions 231 are symmetrically arranged on both sides of the fixed portion 232 along the width direction. The fixed portion 232 is in the shape of a plate, and the contact portion 231 is formed by extending upward from the side edge of the fixed portion 232. The contact portion 231 is an elastic arm, which has contacts 2311 that bulge inwardly toward each other, and the structural form of the elastic arm ensures reliable contact between the contacts. The contacts 2311 on the contact portion 231 of each negative terminal 23 are respectively adapted to the corresponding contacts formed on the second body surface 132 of the negative terminal of the mating connector.

The welding foot 234 of the negative terminal 23 can be formed by extending the bottom plate 222, and can be specifically located at the bottom end of the second body 21; in a specific implementation, a multi-welding foot design can be used to improve welding strength.

Please refer to Figures 11 and 14 together, wherein Figure 14 is a schematic diagram of the contact assembly relationship between the negative terminals of the mating connectors formed from the C-C section position in Figure 11.

As shown in the figure, the four contact portions 221 of the two negative terminals 23 are arranged in 180° rotational symmetry, and have rotationally symmetrical contacts that are adapted to the negative terminals on the mating connector side. When assembled and mated in the 0° direction or the 180° direction, effective electrical connection between the negative terminals of the two can be achieved.

In order to improve the buckling pressure bearing capacity of the two islands 214, the negative terminal 23 in this solution also includes a protective portion 233 formed by bending and extending upward from the edge of the fixed portion 232. The protective portion 233 is located at the edge of the fixed portion 232 close to the corresponding side island 214, and covers the top surface, end surface and end area of the opposite end of the corresponding island 214 to improve the strength of the end area. Here, the negative terminal 23 can be assembled and fixed with the second body 21 in a buckling manner, or it can be integrally formed with the second body 21 by injection molding, and the structure is more reliable.

Of course, the protection portion 233 has a shape that matches the island portion 214, such as but not limited to an extended slope and a rounded corner, etc., which can not only increase the local strength of the island portion 214, but also provide a guiding function during the assembly and insertion process.

Furthermore, in this embodiment, the second connector 20 further includes two protective metal parts 25, which are respectively arranged at the two ends of the second body 21. As shown in Figures 8 and 10, the protective metal part 25 includes an end wall protective part 251 and two side wall protective parts 252, all of which are in the shape of a cover, wherein the end wall protective part 251 is covered on the end wall 212 of the second body 21, and the two side wall protective parts 252 are respectively covered on the side walls 213 of the second body 21, which have the function of protecting the metal fittings and can increase the structural strength of the connector end.

Among them, the top protection segment 2511 of the end wall protection portion 251 is in the shape of an outward convex arc, and the inner protection segment 2512 is formed by extending downwardly from the top protection segment 2511, which has a good insertion guiding effect; similarly, the top protection segment 2521 of the side wall protection portion 252 is in the shape of an outward convex arc, and the inner protection segment 2522 is formed by extending downwardly from the top protection segment 2521. On the whole, good guidance can be achieved in both dimensional directions of the assembly mating plane.

In order to further obtain a good assembly feel, the protective metal part 25 in this solution has a snap-fitting protrusion that is adapted to the pit (1321, 1331) on the mating connector side. Specifically, the inner protective section 2512 of the end wall protective section 251 is provided with a snap-fitting protrusion 25121, which is adapted to the pit 1321 on the mating connector side; the inner protective section 2522 of the side wall protective section 252 is provided with a snap-fitting protrusion 25221, which is adapted to the pit 1331 on the mating connector side. Please refer to Figures 11, 15 and 16 together, wherein Figure 15 is a schematic diagram of the snap-fitting assembly relationship between the mating connectors formed from the D-D section position in Figure 11, and Figure 16 is a schematic diagram of the snap-fitting assembly relationship between the mating connectors formed from the E-E section position in Figure 11.

During the assembly process, the initial metal extrusion force is relatively large and deformed. When the corresponding engaging protrusion is aligned with the concave pit, the extrusion force is reduced and the deformation is released, which can provide a good plugging and unplugging feel. Of course, in other specific implementations, the engaging protrusion and concave pit that are engaged can also be configured in reverse, that is, the engaging protrusion is configured on the first connector side and the concave pit is configured on the second connector side.

It is understandable that the engaging protrusion of the protective metal part 25 and the recess (1321, 1331) on the mating connector side are also arranged in 180° rotational symmetry, and when assembled and engaged in the 0° direction or the 180° direction, both can provide good plugging and unplugging feel.

In addition, in order to effectively improve the structural integration and reduce the space occupied in the length direction, in this embodiment, the protective metal part 25 and the negative terminal 23 located at the end of the second body 21 are staggered in the width direction. As shown in Figures 8 and 10, the inner protective section 2522 of the side wall protective part 252 is provided with a groove 25222, and the position of the groove 25222 corresponds to the contact portion 231 of the negative terminal 23. The contact 2311 on the contact portion 231 can protrude from the inner protective section 2522 through the groove 25222 to adapt to the negative terminal contact portion on the mating connector side. In addition, for the negative terminal 23, the inner protective section 2522 of the side wall protective part 252 can further provide shielding protection, reduce the possibility of short circuit, and enhance safety and reliability.

In addition, in order to further improve the flow capacity, in this embodiment, the protective metal member 25 and the negative terminal 23 are both in contact with the negative terminal on the mating connector side, and here, the protective metal member 25 also has the transmission capacity of the negative terminal. For example, but not limited to, the protective metal member 25 and the negative terminal on the mating connector side can be electrically connected through the matching clamping protrusions and pits.

The welding foot 253 of the protective metal member 25 can be formed by extending the outer protective section 2523 of the side wall protective portion 252 , and can be specifically located at the side edge of the bottom surface of the second body 21 .

In the aforementioned embodiment, the positive terminal and the signal terminal of the first connector 10 are respectively built into the concave accommodating parts formed by different openings. In a specific implementation, the top surface of the first body of the first connector may have an opening for the built-in positive terminal and the signal terminal. Please also refer to FIG. 17, which is a schematic diagram of another connector assembly provided in an embodiment of the present application.

The connector assembly 100a includes a first connector 10a and a second connector 20a that are mutually matched. The first connector 10a and the second connector 20b are respectively arranged on two devices to be connected for mutual matching. Along the direction indicated by the arrow in FIG17(a), the first connector 10a can be inserted and engaged with the second connector 20a to form a connector assembly 100a as shown in FIG17(b). After the first connector 10a and the second connector 20a are inserted and engaged, electrical connection and signal connection between the two devices to be connected can be achieved.

In this embodiment, the first connector 10a includes a first body 11a, a positive terminal 12a, a negative terminal 13a and a signal terminal 14a. Please refer to Figures 18 and 19, wherein Figure 18 is a schematic diagram of the overall structure of the first connector shown in Figure 17, and Figure 19 is an exploded schematic diagram of the assembly of the first connector shown in Figure 17.
