Please refer to fig. 1, which is a schematic cross-sectional view of a connector 300 according to an embodiment of the present application.

As shown in fig. 1, in the present embodiment, a connector 300 according to the present application includes a sheath 200, a connection terminal 100, and a mating port 301. The mating port 301 is secured to the sheath 200. The connection terminal 100 protrudes into the sheath 200 and is connected to the mating port 301. Specifically, the sheath 200 has a housing 210 and a cavity 220, and the cavity 220 is opened inside the housing 210. The mating port 301 is fixed to the sheath 200, i.e., to the housing 210, and is received in the cavity 220. The cavity 220 has opposite ends, one end for insertion of the mating port 301 and the other end for insertion of the connection terminal 100. The mating port 301 is at least partially located within the cavity 220, and the mating port 301 can also transmit signals away from the cavity 220.

The connection terminal 100 protrudes into the cavity 220 and is fixed and communicated with the sheath 200. Specifically, the connection terminal 100 has the tab 11, and when the connection terminal 100 is inserted into the cavity 220 of the sheath 200, the tab 11 is inserted into the cavity 220 from the outside of the housing 210. The contact 11 is inserted into the cavity 220 to at least partially contact the mating port 301, and the contact 11 is electrically connected with the mating port 301 in a matching manner. It should be noted that the contact 11 and the mating port 301 are made of conductive materials, and at least a portion of the conductive materials is in contact with each other, so that electrical connection can be achieved. The housing 210 is made of an insulating material to insulate the connection terminal 100 from the external environment.

It is understood that the connector 300 of the present application may be used to enable signal transmission between wiring harnesses. The two strands are respectively located at opposite ends of the connector 300, i.e., one of the strands is located at an end of the connection terminal 100 facing away from the mating port 301, and the other strand is located at an end (not shown) of the mating port 301 facing away from the connection terminal 100. The two wire harnesses are respectively electrically connected with the connector 11 and the mating port 301. The contact 11 is arranged to be at least partially in contact with the mating port 301 to ensure transmission of a transmission signal between the two strands of wiring harness.

Please refer to fig. 2, which is a schematic structural diagram of a connection terminal 100 according to an embodiment of the present application.

As shown in fig. 2, in the present embodiment, the connection terminal 100 of the present application includes an opposite protruding section 10 and a transmission section 20 along a length direction thereof. The introduction section 10 and the transfer section 20 may be two parts connected on one body. Wherein the penetrating segment 10 is adapted to extend into the cavity 220 of the sheath 200 shown in fig. 1. In the illustration of fig. 1, the portion of the connection terminal 100 inserted into the cavity 220 is the protruding section 10. The protruding section 10 is arranged to protrude into the cavity 220 to perform a connection function with the mating port 301 located in the cavity 220. The transmission section 20 may be used to transmit the signal transmitted to the protruding section 10 to the rear wiring harness, or transmit the signal in the rear wiring harness to the direction of the mating port 301 through the protruding section 10.

It should be noted that, based on different usage scenarios, the connection terminal 100 may be integrally formed as the extending section 10, and the transmission section 20 is a wire harness structure. That is, in the transmission segment 20 illustrated in the figure, the extension segment 10 and the transmission segment 20 are only distinguished functionally, and different usage scenarios are obtained by arbitrary division without clear distinction in structure.

Specifically, please refer to fig. 1 to fig. 4, wherein fig. 3 is a schematic structural diagram of the joint 11 and the fixing element 12 in the connection terminal 100 of the present application, and fig. 4 is a schematic partial structural diagram of the connection terminal 100 of the present application.

In this embodiment, the protruding section 10 may include a joint 11, a fixing member 12, and two sidewalls 13. The joint 11 is fixed to both side walls 13. Or as depicted, two side walls 13 are secured to opposite sides of the fitting 11. The fixing member 12 is also fixed to the two side walls 13. The connector 11 is provided for mating with a mating port 301 secured in the sheath 200 to complete a signal. The fixing member 12 is used to achieve the fixing between the protruding section 10 and the sheath 200, so as to ensure the reliable connection between the connector 11 and the mating port 301.

Further, the fixing member 12 includes a fixed end 121 and a free end 122. The fixed end 121 is an end of the fixing member 12 close to the joint 11, and the free end 122 is an end of the fixing member 12 far from the joint 11. The fixed end 121 is also fixed between the two side walls 13, and the fixing member 12 is relatively close to the two side walls 13. The free end 122 is relatively far from the joint 11 and is closer to the side of the transmission section 20 than the fixed end 121. The sheath 200 has an inner wall 230, and the free end 122 is adapted to abut against the inner wall 230 to prevent displacement of the fastener 12 relative to the housing 210 in the direction of insertion into the cavity 220. That is, the free end 122 serves to prevent the penetrating segment 10 from partially or entirely exiting the cavity 220, ensuring structural stability of the connector 300 of the present application.

Further, the fixing member 12 may further include a holding portion 123. The number of the holding parts 123 is two. Two holding portions 123 are arranged on both sides of the fixing member 12. Correspondingly, each side wall 13 is provided with one abutting portion 131, that is, the number of abutting portions 131 is two. The abutting portion 131 is disposed corresponding to one of the holding portions 123, and the abutting portion 131 is used for limiting the displacement of the holding portion 123, so as to ensure the stability of the posture of the fixing member 12 in the cavity 220, and further ensure the holding effect of the free end 122 on the position of the extending section 10.

In one embodiment, the holding portion 123 is located between the abutting portion 131 and the contact 11 in a direction perpendicular to the length direction of the connection terminal 100. That is, the abutting portion 131 is located on a side of the holding portion 123 facing away from the contact 11 to limit the holding portion 123 from moving in a direction away from the contact 11. The holding portion 123 and the abutting portion 131 cooperate with each other to restrict the free end 122 of the fixing piece 12 from moving further away from the joint 11. Meanwhile, the holding portion 123 is also located between the fixed end 121 and the free end 122, so as to ensure that the free end 122 can abut against the inner wall 230 of the sheath 200, and prevent the free end 122 from moving further away from the connector 11.

The structure of this application mounting 12 is simple relatively, and the volume is less. It is also possible in the prior art for connector 300 to employ a similar fastener 12 configuration, with a similar free end 122 configuration abutting against the inner wall 230 of the sheath 200 to limit relative displacement between the prior art sheath and the connection terminal. However, the structure similar to the fixing member 12 in the prior art does not have a fitting structure similar to the holding portion 123 and the abutting portion 131, and the prior art lacks a restriction on the displacement of the fixing member itself. At this time, the free end of the related art fixing member may be displaced or warped during the pressing process with the inner wall 230 of the sheath 200, thereby reducing the holding force of the related art connection terminal in the cavity 220, resulting in a decrease in connection stability, and even causing a connection drop-off phenomenon.

The fixing part 123 is arranged on the fixing part 12, the abutting part 131 is arranged on the side wall 13 in a matched mode, the fixing part 123 and the abutting part 131 are matched with each other to limit the free end 122 to move further in the direction away from the joint 11, a good protection effect can be achieved on the free end 122, and the holding force of the connecting terminal 100 in the cavity 220 is increased. Meanwhile, the connection terminal 100 of the present application further has holding portions 123 disposed on both sides of the fixing member 12, and two abutting portions 131 are disposed on the two sidewalls 13, respectively. The two holding portions 123 are respectively matched with the two abutting portions 131 to respectively hold two sides of the free end 122, so that the stress uniformity of the free end 122 is improved, the free end 122 can be prevented from being deformed or being overturned on one side, and the structural stability of the connecting terminal 100 is improved.

As shown in fig. 3, in one embodiment, the free end 122 is provided with a rib 1221 configuration. The bead 1221 is located on the side of the free end 122 facing away from the joint 11. It can be understood that the rib 1221 is disposed to increase the strength of the free end 122, so as to prevent the free end 122 from being damaged due to excessive pressing with the inner wall 230, and further prevent the free end from being pressed against the inner wall 230.

Referring to fig. 2 to 4, in an embodiment, the holding portion 123 includes a bump 1231, and the abutting portion 131 includes a hollow 1311. Each holding portion 123 is configured as a bump 1231, and each abutting portion 131 is correspondingly configured as a hollow 1311. The hollow 1311 is formed by a through hole formed in the sidewall 13. Each projection 1231 projects toward the opposite sidewall 13 and may project into the opposite hollow 1311. The bump 1231 may further abut against an inner surface of the hollow area 1311, that is, the bump 1231 may abut against an inner surface of the hollow area 1311 away from the joint 11. It can be understood that the hollow area 1311 can limit the displacement of the protrusion 1231 toward the direction away from the joint 11, that is, can limit the free end 122 of the fixing member 12 from further moving toward the direction away from the joint 11, so as to achieve the effect of the mutual cooperation between the holding portion 123 and the abutting portion 131.

Please refer to fig. 5, which is a schematic structural diagram of a connection terminal 100 according to another embodiment of the present disclosure.

As shown in fig. 5, in one embodiment, the hollow area 1311 is formed as a notch on the sidewall 13. It can also be described that one side of the hollow area 1311 is provided in the shape of an opening. The protrusion 1231 extends into the hollow 1311 and abuts against the inner surface of the hollow 1311 away from the joint 11, so as to limit the free end 122 from moving further in a direction away from the joint 11.

Referring to fig. 6 and 7, fig. 6 isbase:Sub>A perspective view of the fixing member 12 and the two side walls 13 on the same plane according to an embodiment, and fig. 7 isbase:Sub>A schematic sectional view taken alongbase:Sub>A-base:Sub>A of fig. 6.

In the illustrated embodiment, abutment 131 includes a flange 1312, or may be described as abutment 131 being secured to sidewall 13 in the form of flange 1312. The number of the flanges 1312 is two, one flange 1312 is provided on each side wall 13, and in the present embodiment, the flanges 1312 are configured as bosses. Note that, for convenience of description, one of the two side walls 13 is defined as a side wall 13a, and the other is defined as a side wall 13b. Specifically, one of the flanges 1312 protrudes from the side wall 13a in the direction toward the side wall 13b, and the other flange 1312 protrudes from the side wall 13b in the direction toward the side wall 13 a. At this time, the two holding portions 123 corresponding to the two abutting portions 131 are respectively two sides of the fixing member 12. Each flange 1312 may be adapted to abut against one side of the fastener 12, and the two flanges 1312 may effectively limit the displacement of the free end 122 away from the joint 11. It can be understood that, in the embodiment, since the two side edges of the fixing member 12 can be directly used as the holding portion 123, the shape of the fixing member 12 can be simplified, which is beneficial to the processing and manufacturing of the fixing member 12.

Referring to fig. 8 and 9, fig. 8 is a perspective view of the fixing member 12 and the two side walls 13 on the same plane in another embodiment, and fig. 9 is a cross-sectional view at B-B in fig. 8.

In one embodiment, the thickness of the flange 1312 is set to be the same as the thickness of the sidewall 13. At this time, the flange 1312 may be punched out of the side wall 13. It can be appreciated that in the present embodiment, the flange 1312 is directly formed as the abutting portion 131 by stamping the body of the sidewall 13, and there is no need to provide a similar boss (shown in fig. 6 and 7) or other structure on the sidewall 13 to cooperate with the holding portion 123, so that the process can be further simplified.

In one embodiment, the fastener 12 is resilient in its entirety, or the free end 122 of the fastener 12 is resilient. The resilient fixing element 12 or the free end 122 can be deformed by itself to ensure that the penetrating segment 10 extends into the cavity 220 or is pulled out of the cavity 220. Meanwhile, after the extending section 10 completely extends into the cavity 220, the elastic free end 122 can form a holding fit with the inner wall 230 through resilience, so as to limit the relative position of the extending section 10 and the sheath 200.

In one embodiment, the joint 11 and the fixing member 12 are a unitary structure, and the joint 11 is welded and fixed between the two side walls 13. It will be appreciated that the joint 11 and the fixing member 12 are integrally formed, and the joint 11 is welded and fixed between the two side walls 13, that is, the fixing member 12 is also fixed between the two side walls 13, so that the process can be simplified. Meanwhile, the fixing element 12 is fixed between the two side walls 13, so that the abutting effect of the free end 122 and the inner wall 230 can be improved, and the reliability of the connection terminal 100 of the present application can be further improved.

Referring to fig. 1-4 in combination, in one embodiment, the insertion section 10 may further include a connection portion 14. The connecting portion 14 is located on a side of the joint 11 facing away from the fixing member 12 and between the two side walls 13 to connect and fix the two side walls 13. As can be understood, based on the fact that the two side walls 13 are connected and fixed by the connecting portion 14, the structural stability of the side walls 13 can be enhanced, and the reliability of the cooperation of the holding portion 123 and the abutting portion 131 for limiting the displacement of the free end 122 is ensured.

In one embodiment, the penetrating segment 10 may further include a top wall 15. The top wall 15 is located on the side of the joint 11 facing away from the connecting portion 14 and at the end of the intake section 10 near the transmission section 20. The top wall 15 extends from one of the side walls 13 toward the other side wall 13 and is fixedly connected to the other side wall 13. That is, the two side walls 13 are also connected and fixed by the top wall 15. It will be appreciated that the two side walls 13 of the entry section 10 are connected and fixed by the top wall 15 near one end of the transfer section 20, which further enhances the structural stability of the side walls 13.

Referring to fig. 1 and 3, it can be understood that in the illustration of fig. 1 and 3, the connector 11 is formed by two contact elastic sheets 111 arranged at intervals, and the corresponding mating port 301 is arranged in the form of a pin. The two contact spring pieces 111 are used for clamping the matched pins 231 to form connection conduction.

It should be noted that the embodiments shown in fig. 1 to fig. 7 related to the connector 11 and the mating port 301 are only used as some exemplary descriptions, and do not represent the actual shapes and structures of the connector 11 and the mating port 301. In other embodiments, the shapes and structures of the connector 11 and the mating port 301 may be adjusted according to actual conditions, as long as the connector 11 is electrically connected to the mating port 301.

Illustratively, in one embodiment, when the header 11 is provided in the form of a socket, the corresponding mating port 301 may be provided in the form of a pin; when the contacts 11 are provided in the form of pins; the corresponding mating port 301 may be provided in the form of a socket; when the contacts 11 are provided in the form of contact springs 111, the corresponding mating ports 301 may also be provided in the form of contact springs 111.

Referring to fig. 1 and 3, when the connector 11 is formed by two contact elastic pieces 111 arranged at intervals and the mating port 301 is correspondingly arranged as a pin, the free end 122 forms an approximately V-shaped included angle with the cross section of one contact elastic piece 111 close to the free end 122. The end of the free end 122 not abutted against the inner wall 230 can be abutted against the contact spring 111, that is, the portion of the free end 122 connected to the fixed end 121 can be used for abutting against the contact spring 111. During operation of the connector 300, the two contact springs 111 are subjected to a force applied by the connecting portion 14 toward the contact 11 and a force applied by the free end 122 toward the contact 11. It can be understood that, since the two forces are applied in opposite directions, the mating port 301 in the form of a pin can be reliably clamped, so that the pin and the two contact spring pieces 111 are reliably contacted, and thus, signals can be reliably transmitted between the connector 11 and the mating port 301.

In one embodiment illustrated in fig. 2, the transmission section 20 comprises an insulation rivet 21, a conductor rivet 22, and a transition zone 23. The transition zone 23 is located on the side of the conductor rivet 22 facing away from the insulating rivet 21, i.e. the conductor rivet 22 is located between the insulating rivet 21 and the transition zone 23. It should be noted that the wire harness has a wire core and an insulating sheath, and the insulating sheath is used for wrapping the wire core. The core of the wire harness is exposed from the insulation sheath and fixed to the conductor rivet 22, and the insulation sheath covering the core is fixed to the insulation rivet 21 (not shown). Note that, in order to clearly illustrate the structure of the connection terminal 100, the structure and the position of the wire harness are not shown in the drawing.

The cross sections of the insulating riveting claw 21 and the conductor riveting claw 22 are approximately U-shaped, so that the conductor riveting claw 22 can be used for reliably riveting a wire core of a wire harness, and the insulating riveting claw 21 can be used for reliably riveting an insulating skin wrapping the wire core. The insulating rivet 21 may be used to limit the swing arc of the wire harness in the connection terminal 100 to prevent the wire core from being broken due to a large swing. The wire core is secured to conductor rivet 22 and current and signals are transmitted between terminal 100 and the wiring harness through conductor rivet 22. The transition region 23 is used for connection and transition, so that the current and the signal at the rear end can be stably transmitted to the protruding section 10, or the current and the signal transmitted from the mating port 301 to the protruding section 10 can be stably transmitted to the rear end.
