Description

Electrical connector for compact systems

Technical Field

The present invention relates to an electrical connector for compact systems.

Background

Electrical connectors are used in many electronic systems. Manufacturing a system on several Printed Circuit Boards (PCBs) connected to each other by electrical connectors is generally easier and more cost effective than manufacturing a system as a single component. Conventional arrangements for interconnecting several PCBs typically use one PCB as a backplane. Other PCBs, called daughter boards or daughter cards, are then connected to the backplane by electrical connectors to effect interconnection of the PCBs.

Electronic systems generally tend to be miniaturized in design. This means that the space occupied by the electrical connector is left more narrow. In existing designs, the electronic card may be retained within a slot of an electrical connector. When the electronic card needs to be taken out, the unlocking part needs to be pulled outwards towards the extending direction of the slot, and the electronic card can be taken out. Therefore, the outer circumference of the electrical connector needs a certain space for the unlocking member to be pulled outward. How to reduce the space required by the electrical connector is a major topic discussed in this application.

Detailed Description

In the following description, numerous details are provided to provide a thorough understanding of the present invention. One skilled in the art, however, will understand that the following description merely illustrates a preferred embodiment of the utility model and that the utility model may be practiced without one or more of these details. In other instances, well known features have not been described in detail so as not to obscure the utility model.

The inventors have recognized that the space occupied by the electrical connectors needs to be further compressed in order to achieve miniaturization of electronic systems. The inventors have recognized and appreciated the design of an electrical connector for a compact system (hereinafter referred to as an electrical connector) that reduces the footprint. In some embodiments, an electrical connector may include a resilient latch. In the conventional electrical connector, the unlocking member needs to be pulled outward toward the extending direction of the slot, so that a certain space needs to be reserved around the electrical connector. In embodiments of the utility model, the resilient locking element may be disposed within the slot. The resilient latch may retain the electronic card within the slot. When the elastic locking piece is subjected to external force, the electronic card can be unlocked, so that the electronic card can be taken out from the slot. Therefore, no space is required around the electrical connector, and the space occupied by the electrical connector is reduced. The electrical connector of some embodiments is described in detail below with reference to specific embodiments.

As shown in fig. 1-12, an electrical connector may include an insulative housing 100, a resilient latch 200.

The insulating housing 100 may have a mating face 101 and a mounting face 102. The docking surface 101 may be provided with a slot 110 depressed in a first direction. The socket 110 may be used to receive electrical components such as electronic cards, plug electrical connectors, and the like. The electrical components are described below with the electronic card 900 as an example.

The slot 110 is substantially in the shape of a long and narrow strip. The mounting surface 102 may face a printed circuit board or the like. Specifically, an electronic card may be inserted into the slot 110 of the mating face 101, and the mounting face 102 may be connected to the printed circuit board, so that the electronic card and the printed circuit board are electrically connected through an electrical connector, thereby realizing interconnection of circuits on the electronic card and circuits on the printed circuit board. Illustratively, a plurality of conductors 800 may be disposed on the insulating housing 100. One end of the conductor 800 extends into the socket 110 and the other end of the conductor 800 extends beyond the mounting face 102 for electrical connection with a printed circuit board. The conductor 800 may be electrically connected to the printed circuit board by any suitable means, such as soldering. Conductors 800 may include, but are not limited to, one or more of signal conductors, ground conductors, and the like. The different types of conductors 800 may be arranged in any pattern on the insulating housing 100. The present invention does not improve upon the conductors 800 themselves and, in order to avoid confusion, they will not be described in further detail herein.

The resilient latch 200 may be disposed within the slot 110. In the embodiment shown in the figures, referring to fig. 8, the resilient latch 200 may be plugged into the slot 110. In other embodiments not shown, the resilient locking element 200 may be disposed within the slot 110 by any suitable means, such as welding or gluing. The electronic card 900 may be provided with an adaptive locking portion 910. The resilient latch 200 may be configured to mate with the mating latch 910 so that the electrical component 900 may be retained within the socket 110; and the resilient latch 200 may also be configured to disengage the mating latch 910 under an external force. The external force refers to an external force applied to the electrical connector and/or the electronic card 900 by an operator, such as a force pressing the elastic locking member 200, a force pushing the electronic card 900, a force pulling the electronic card 900, and the like.

In the embodiment shown in the figures, referring to fig. 5, the mating lock 910 may include a groove and the resilient locking element 200 may have a resilient projection. In other embodiments not shown, the mating lock 910 may include a protrusion and the resilient locking element 200 may include a resilient groove. The resilient locking element 200 and the mating locking portion 910 may also be any other suitable structure that performs the above-described functions.

Specifically described with the embodiments shown in the figures, when it is desired to mount the electronic card 900, an external force may be applied to insert the electronic card 900 into the receptacle 110 in a first direction. During the insertion process, the adaptive locking portion 910 of the electronic card 900 can press the elastic locking portion 200, so that the elastic locking member 200 is elastically deformed, and the electronic card 900 can be further inserted. When the electronic card 900 is inserted to a predetermined position, the elastic locking member 200 may restore to a natural shape, and the adaptive locking portion 910 is engaged with the elastic locking member 200, and then the electronic card 900 may be held in the slot 110. When it is desired to remove the electronic card 900, an external force opposite to the insertion direction may be applied, such as pulling the electronic card 900. During the pulling process, the adaptive locking portion 910 of the electronic card 900 may press the elastic locking member 200, so that the elastic locking member 200 is elastically deformed, and the adaptive locking portion 910 is disengaged from the elastic locking member 200, and then the electronic card 900 may be taken out. When the electronic card 900 is removed, the elastic locking member 200 can restore to its natural shape.

In the electrical connector of the embodiment of the present invention, the elastic locking member 200 is disposed in the slot 110. It is not necessary to reserve a sufficient operating space for the elastic locking member 200 at the outer peripheral side of the electrical connector, and therefore, the gap between the electrical connector and the adjacent device on the printed circuit board can be reduced, thereby providing a possibility for miniaturization of the electronic system.

Preferably, as shown in fig. 1-12, the electrical connector may further include an unlocking assembly 300. The unlocking assembly 300 may be provided on the insulating housing 100. The unlocking assembly 300 may have an operable portion 301. The operable portion 301 may be movable in the second direction. The second direction may be parallel to the first direction. The unlocking assembly 300 may be configured to lift the electronic card 900 by movement of the operable portion 301 so that the mating locking portion 910 is disengaged from the resilient locking member 200.

Specifically, when the electronic card 900 needs to be taken out, the operable portion 301 may be operated (e.g., pressed or pulled) in the second direction. At this time, the operable portion 301 may drive the mobile unlocking assembly 300 to move, so as to lift the electronic card 900. Unlocking assembly 300 may include various types of transmission members that translate movement of manipulatable portion 301 in the second direction into lifting of electronic card 900. During the lifting process, the adaptive locking portion 910 of the electronic card 900 can elastically deform the elastic locking member 200, so that the adaptive locking portion 910 is disengaged from the elastic locking member 200, and then the electronic card 900 can be taken out. When the electronic card 900 is removed, the elastic locking member 200 can restore to its natural shape. When it is desired to install the electronic card 900, the electronic card 900 may be directly inserted into the receptacle 110 in a first orientation. During the insertion process, the adaptive locking portion 910 of the electronic card 900 can elastically deform the elastic locking member 200, so that the electronic card 900 can be further inserted until the electronic card 900 is inserted to a predetermined position, the elastic locking member 200 can recover to a natural shape, the adaptive locking portion 910 is engaged with the elastic locking member 200, and then the electronic card 900 can be retained in the slot 110.

In the electrical connector of the embodiment of the present invention, the operable portion 301 of the unlocking assembly 300 can be operated in a direction parallel to the insertion direction of the electrical component (e.g., the electronic card 900) by the user's operation, there is generally sufficient operating space in the direction of inserting the electrical component without reserving sufficient operating space for the unlocking assembly 300 on the outer peripheral side of the electrical connector, and therefore, the gap between the electrical connector and the adjacent device on the printed circuit board can be reduced, thereby providing a possibility for miniaturization of the electronic system.

The structure of the operable portion 301 may be arbitrary. For example, the operable portion 301 may have a large contact surface. This makes it possible to easily find the operable portion 301, and to reduce the pressure applied to the operable portion 301 by the user, thereby improving the use experience. The operable portion 301 may have a non-slip layer thereon, such as a frosted layer, a rubber layer, or the like. This can prevent the operable portion 301 from being too smooth to cause an operation object (e.g., a user's hand) to slip off the operable portion 301. The operable portion 301 may be made of an insulating material, for example, the same material as the insulating housing 100. This prevents static electricity from being generated during operation, thereby causing damage to the electrical connector and the electronic card 900.

The resilient latch 200 and the unlatching member 300 may be disposed on the same side of the socket 110. Optionally, a resilient latch 200 and a latch assembly 300 may also be provided on other sides of the socket 110. Of course, the resilient locking element 200 and the unlocking element 300 may also be arranged on different sides of the socket 110. Preferably, as shown, the resilient latch 200 and the latch assembly 300 are provided in pairs. Each pair of resilient locking elements 200 may be disposed on two sides, e.g., opposing first and second sides, respectively, of the slot 110. Each pair of unlocking members 300 may be disposed on two sides, such as opposite third and fourth sides, of the slot 110, respectively. The first side and the second side may be the same side as the third side and the fourth side, respectively, or may be completely different sides from the third side and the fourth side. It is understood that the electronic card 900 may also be provided with mating locks 910 at corresponding locations on both sides thereof. Thus, the mating locking portions 910 on both sides of the electronic card 900 can be respectively engaged with the corresponding elastic locking elements 200, so that the electronic card 900 is held in the slot 110 by a uniform force. The electronic card 900 is more strongly connected to the socket 110. When the unlocking assemblies 300 on both sides are operated simultaneously, the electronic card 900 may be lifted by the movement of its own operable portion 301, so that the adaptive locking portion 910 is disengaged from the elastic locking member 200. The electronic card 900 is uniformly stressed on both sides, preventing the electronic card 900 from being damaged due to stress on one side. For the card edge connector shown in the figures, the resilient latch 200 and the unlatching assembly 300 are more likely to be disposed in the tower of the card edge connector because there is enough space to dispose them.

In a preferred embodiment, as shown in fig. 8, the resilient locking element 200 may comprise a holder 210 and a resilient tab 220. The fixing base 210 may be disposed in the slot 110 by any suitable manner, such as plugging, welding, or bonding. The resilient tab 220 may extend cantilevered from the anchor mount 210. The middle portion of the elastic piece 220 may be bulged toward the inside of the insertion groove 110. The middle portion of the elastic piece 220 may form a protrusion portion to be mated with the mating locking portion 910 of the electronic card 900. The elastic piece 220 with one end suspended is more easily elastically deformed under the action of external force. Specifically, when the middle portion of the elastic piece 220 is in the natural shape, it can be held in the adaptive locking portion 910 of the electronic card 900, so that the electronic card 900 can be held in the slot 110. During the lifting and inserting process, the adaptive locking portion 910 of the electronic card 900 may press the middle portion of the elastic sheet 220 so that it may be pressed and deformed, so that the adaptive locking portion 910 of the electronic card 900 may pass through, and the electronic card 900 may be taken out and inserted. Therefore, the elastic locking element 200 has a simple structure, low manufacturing cost and reliable performance.

The elastic sheet 220 may have a connection end 221 connected to the fixing base 210 and a cantilever end 222 away from the connection end 221. Further, the cantilever end 222 of the elastic sheet 220 is located inside the insertion slot 110 compared to the connection end 221 of the elastic sheet 220. Thus, during the insertion of the electronic card 900, the cantilever ends 222 can be more easily extended downward, so that the insertion process is smoother. When the electronic card 900 is removed, the cantilever end 222 tends to move upward along with the mating locking portion 910 of the electronic card 900, so that a relatively large external force may be applied to disengage the mating locking portion 910 from the elastic piece 220, thereby preventing the electronic card 900 from being accidentally disengaged from the electrical connector.

In a preferred embodiment, as shown in fig. 4-9, the unlocking assembly 300 may include a pusher 310 and a lifter 320. The pusher 310 is reciprocally movable along the second direction. The pusher 310 may include an outer end 340 and an inner end 330. The outer end 340 may be exposed to the outside of the insulation case 100. The operable portion 301 may be disposed on an outer end 340 of the pusher 310. The inner end of the pusher 310 may engage the lifting member 320 by any suitable means, such as abutting, welding, or gluing. Preferably, the pusher 310 may be a unitary piece. The manner of forming the unitary member is not limited and includes, but is not limited to, one or more of integral molding, welding, bonding, and the like. Thus, the structure of the propelling member 310 is more compact and the mechanical strength is higher.

The lifting member 320 may be used to transfer the movement of the pusher 310 to the electronic card 900 so that the electronic card 900 may be lifted. Specifically, the operable portion 301 is operated to move the pusher 310 along the second direction, and the pusher 310 lifts the electronic card 900 by the lifting member 320, so that the electronic card 900 can be taken out. The pusher 310 moves only in the second direction, and the lifting member 320 is used to translate the movement in the second direction into the lifting of the electronic card 900. The unlocking assembly 300 has the advantages of simple structure, low manufacturing cost and reliable performance.

As shown in fig. 9, the inner end 330 of the pusher 310 may have a contact surface 360. The contact surface 360 may abut the lift 320. By providing the contact surface 360, the engaging area of the inner end portion 330 and the lifting member 320 can be increased, thereby reducing the pressure and preventing damage to the two.

As shown in fig. 4-5, the lifting member 320 may be located at the bottom of the socket 110. The lifting member 320 may be used to lift an insertion end of the electronic card 900 (in the figure, a lower end of the electronic card 900). If the lifting member 320 is applied to the side of the electronic card 900, it may be necessary to provide a corresponding structure, such as a protrusion or a groove, on the side of the electronic card 900 to facilitate the holding of the lifting member 320. As such, modifications to the electronic card 900 may be required. The lifting member 320 acts on the insertion end of the electronic card 900 without modification to the structure of the electronic card 900. Therefore, the electric connector is highly practical. Furthermore, the lifting member 320 acts on the bottom of the electronic card 900, and the mechanical strength is greater than that of the aforementioned additionally arranged protrusion or recess, and the electronic card 900 is not easily damaged when the lifting member 320 acts thereon.

As shown in fig. 4-8, the lifting member 320 is pivotably disposed within the insulated housing 100. In the embodiment shown in the figures, the lifting member 320 may be provided with a lifting shaft hole 326, the insulating housing 100 may be provided with a housing shaft hole 140, and the electrical connector may further include a pivot 160. The pivot shaft 160 can pass through the lift shaft aperture 326 and the housing shaft aperture 140 such that the lift member 320 is pivotably disposed within the insulated housing 100. In other embodiments not shown, the lifting member 320 may be provided with a pivot shaft, and the insulating housing 100 may be provided with a shaft hole; or the insulating case 100 may be provided with a pivot and the lifting member 320 may be provided with a shaft hole, etc. The pusher 310 and the electronic card 900 may be engaged to the lift 320 in a first position and a second position, respectively. The pivotable lifting member 320 may transmit the movement of the pushing member 310 in the second direction in the same direction, and specifically, when the pushing member 310 moves upward, the second position may be pulled and also moved upward, so that the lifting member 320 may lift the electronic card 900. Alternatively, the lifting member 320 may transmit the movement of the pushing member 310 in the second direction in the opposite direction, and specifically, when the pushing member 310 moves downward, the pushing member may push the second position to move upward, so as to lift the electronic card 900.

Further, as shown in FIG. 9, the pivot axis P-P of the lifting member 320 may be located in the middle thereof. The pusher 310 may be coupled to the first end 321 of the lifter 320. The second end 322 of the lift 320 may be used to lift the electronic card 900. I.e., the aforementioned first position is located on the first end 321, and the second position is located on the second end 322. That is, pusher 310 and electronic card 900 act on either side of pivot axis P-P, respectively. When both the pusher 310 and the electronic card 900 act on the lift 320 on the same side of the pivot axis P-P, the pusher 310 and the electronic card 900 have the same tendency to move. In the embodiment shown in the figures, second end 322 of lift 320 may abut an insertion end of electronic card 900, thereby lifting electronic card 900. In other embodiments not shown, the second end 322 of the lifting member 320 may abut against other portions of the electronic card 900, such as a groove on a side portion, so as to lift the electronic card 900.

With this arrangement, by pressing the operable portion 301, the pusher 310 can be caused to press the first end 321 of the lifter 320. The second end 322 of the lifting member 320 may be tilted upward to lift the electronic card 900. Compared with other operation modes, the pressing mode is more comfortable, and the use experience is better.

Still further, as shown in fig. 9, the lift 320 may include an engagement arm 324 and a lift arm 325. The engaging arm 324 and the lifting arm 325 may be connected to each other in a V-shape. The pivot axis P-P may be located at the connection of the engaging arm 324 and the lifting arm 325. The first end 321 may be located on the engagement arm 324. The second end 322 may be located on the lift arm 325. The opening of the V-shape may be directed towards the abutment surface 101. The angle between the engagement arm 324 and the lifting arm 325 may be obtuse. Thus, the lifting arm 325 may engage the insertion end of the electronic card 900, and the engaging arm 324 may be tilted upward to allow sufficient space for the first end 321 to move.

Preferably, the first end 321 may be a distance from the pivot axis P-P that is less than the distance from the second end 322 to the pivot axis P-P. In this way, the distance to press the operable portion 301 can be shortened, thereby further reducing the space required to unlock the electronic card 900 on the electrical connector.

In a preferred embodiment, as shown in fig. 10-12, the insulation case 100 may be provided with a mounting groove 120. The mounting groove 120 may include a rail groove 123, a through groove 124, and first and second notches 121 and 122. The rail groove 123 and the through groove 124 may extend from the butting face 101 in the second direction. The rail groove 123 may be provided in a sidewall of the insulation case 100. The through groove 124 may communicate the middle portion of the rail groove 123 and the outer side surface of the sidewall. The through groove 124 may communicate the rail groove 123 with the outside. The width of the through groove 124 may be smaller than the width of the rail groove. The first and second notches 121 and 122 may extend from the through groove 124 to both sides, respectively, and may communicate the rail groove 123 and the outer side surface of the sidewall. The first and second notches 121, 122 may be the same or different. The insulation case 100 is cut perpendicular to the first direction at the non-first and second notches 121 and 122, and the mounting groove 120 is substantially T-shaped. The insulation case 100 is cut perpendicular to the first direction at the first and second notches 121 and 122, and the mounting groove 120 is substantially rectangular.

As shown in fig. 8-9, the pusher 310 may further include a shaft 350, a first lug 361, and a second lug 362. The stem 350 may be connected between the outer end 340 and the inner end 330. The first and second lugs 361 and 362 may protrude from the shaft portion 350 to both sides, respectively. During the installation of the push member 310 into the rail groove 123 via the through-groove 124, the first and second lugs 361 and 362 may enter the rail groove 123 via the first and second notches 121 and 122, respectively. Specifically, the shaft portion 350 may be aligned with the through-slot 124, the first and second lugs 361 and 362 may be aligned with the first and second notches 121 and 122, respectively, and then the shaft portion 350 may pass through the through-slot 124, and the first and second lugs 361 and 362 may pass through the first and second notches 121 and 122, respectively, so that the shaft portion 350, the first and second lugs 361 and 362 may enter the track slot 123. The mounted push member 310 may be movable along the track groove 123. The electrical connector may also include a closure 400, as shown in fig. 8. The block piece 400 may be used to confine the pusher 310 within the mounting slot 120. With this arrangement, the structure of the propelling part 310 is simple, the difficulty of the installation process is low, and the manufacturing is convenient.

The closure 400 may include various structures, for example, the closure 400 may be a structure that closes all or part of the through-groove 124, a structure that closes the through-groove 124, the first gap 121, and the second gap 122, and the like. Preferably, as shown in fig. 8, the closure 400 may comprise a first closure 410 and a second closure 420. The first closure 410 may be inserted into the first indentation 121. The second closure 420 may be inserted into the second gap 122. With this arrangement, the plugging member 400 uses less material, so that the manufacturing cost can be reduced.

Preferably, as shown in fig. 8 to 9, the shaft 350 may further be provided with a third lug 363 and a fourth lug 364 respectively protruding to both sides. Thus, when the push member 310 moves along the rail groove 123, the first lug 361, the second lug 362, the third lug 363, and the fourth lug 364 may contact the groove wall of the rail groove 123 and the lever 350 may be spaced apart from the rail groove 123 in a direction perpendicular to the extending direction of the socket 110 in the horizontal plane. Therefore, the friction between the propelling part 310 and the track groove 123 is reduced, so that the propelling part 310 moves more smoothly along the installation groove 120, and the wear rate of the propelling part 310 and the installation groove 120 can be reduced, thereby prolonging the service life of the propelling part 310 and the installation groove 120. In addition, the reduction in contact area may also improve the machining tolerance.

Further, as shown in fig. 8-9, a third lug 363 may be located between the first lug 361 and the outer end 340. The fourth lobe 364 may be located between the second lobe 362 and the outer end 340. Thus, when the pushing element 310 is installed, the third lug 363 and the fourth lug 364 can be inserted along the track groove 123 from above the insulating housing 100, so that the insulating housing 100 can be free from being provided with notches matched with the third lug 363 and the fourth lug 364. Therefore, the structure of the electric connector is simpler, and the manufacturing cost is lower.

Preferably, the mounting groove 120 may further include an inner groove 125, as shown in fig. 10-12. The inner groove 125 may be recessed toward the insertion groove 110 from a side of the rail groove 123 opposite to the through groove 124. The inner groove 125 may extend in the second direction. Inner groove 125 may be aligned with stem 350. Through setting up inner groovy 125, can make mounting groove 120 and pole portion 350 spaced apart to further reduce the friction between the two, make the removal of impeller 310 along mounting groove 120 more smooth and easy, but also can reduce the wearing and tearing speed of impeller 310 and mounting groove 120, improve both's life. In addition, the reduction in contact area may also improve the machining tolerance.

Preferably, the inner end 330 of the pusher 310 may extend into the through slot 124. In this way, the space through the slot 124 can be utilized to increase the size of the inner end portion 330 as much as possible, and thus the engaging area with the lifting member 320 can be increased, thereby reducing the pressure and preventing damage to the two.

Preferably, referring to fig. 4-7, 9 and 12 in combination, the end of the rail groove 123 remote from the abutment surface 101 (i.e., the lower end in the drawings) may be provided with a stopper groove 130. The stopper groove 130 may be disposed opposite to the through groove 124. The inner end portion 330 of the push member 310 may be bulged toward the catching groove 130. The raised portion may be received within the retaining groove 130 during reciprocation of the pusher 310. The distance between the raised portion and the first protrusion 361 may be greater than the distance between the stopper groove 130 and the first indentation 121. When the first protrusion 361 is aligned with the first notch 121 during the process of installing the push member 310, the raised portion may be inserted into the stopper groove 130. After the installation is completed, the pusher 310 cannot be detached from the insulating housing 100 because the raised portion cannot enter the upper portion of the rail groove 123 after the first notch 121 is closed by the closing member 400.

Further, referring to fig. 4-7, 9, and 12 in combination, the face of the restraint slot 130 opposite the through slot 124 may be a ramped surface 150. The ramp 150 may be inclined toward the socket 110 in a direction away from the mating face 101. The spacing groove 130 is gradually narrowed in an upward direction. When the pushing member 310 moves upward, the inclined surface 150 has a certain buffer to the inner end 330 of the pushing member 310, and the hand feeling is better when in use.

Preferably, as shown in fig. 9, the inner end portion 330 of the push member 310 may have a hook shape. The inner end portion 330 may include an inner starting section 331, an inner tail section 332, and an inner bend section 333. The inner inflection segment 333 may be connected between the inner initial segment 331 and the inner tail segment 332. Inner initiator 331 may extend from stem 350 toward socket 110. The inner tail section 332 may extend from the inner bend section 333 toward the through slot 124. In this way, the contact area of the inner end portion 330 with the lifting member 320 can be increased, thereby making the engagement therebetween more stable. Further, the inner tail section 332 may engage the lift 320 by abutting the lift 320. Therefore, the production process is simpler, and the production efficiency can be improved.

Preferably, as shown in fig. 9, the outer end 340 of the pusher 310 may include an outer initial section 341, an outer tail section 342, and an outer bent section 343. The outer bend 343 may be connected between the outer initial section 341 and the outer tail section 342. An outer initiator section 341 may extend from the stem 350 between the outer end 340 and the inner end 330 toward the socket 110. The outer tail section 342 may extend from the outer bent section 343 in a direction away from the insertion slot 110. Thereby, a substantially hook-shaped outer end 340 may be formed. The operable portion 301 may be located on a top surface of the outer bend 343. When in use, a user can press the top surface of the outer bending section 343, which has a larger contact area, thereby improving the use experience of the operation operable portion 301.
