Therefore, automobiles will add terminal resistance at the transmission terminal to eliminate signal interference.

[0003] The terminal resistor is usually wrapped together with the wiring harness of the car. However, the cross-sectional area of ​​the terminal resistor currently on the market is large. When the terminal resistor is wrapped together with the wiring harness, the wiring harness becomes very thick at the wrapping point. The wiring harness is prone to get stuck during the mobile installation process, which is inconvenient to install. Utility Model Content

[0004] The purpose of the present application is to provide a terminal resistor, a wiring harness assembly and a vehicle, all of which solve the problem that the terminal resistor has a large cross-sectional area and is inconvenient to install the wiring harness.

The cross-sectional area of ​​the terminal resistor is smaller. Furthermore, when the terminal resistor is wrapped with the wiring harness, the thickness of the wiring harness at the wrapping part is smaller, which avoids the wiring harness from getting stuck during the mobile installation process, facilitates installation, and helps improve installation efficiency.

[0007] In some embodiments, the first conductive terminal and the second conductive terminal are all disposed in the housing. This design is conducive to improving the insulation performance of the terminal resistor.

[0008] In some embodiments, the first conductive terminal, the first pin, the second pin and the second conductive terminal are sequentially arranged in a straight line. The cross-sectional area of ​​the terminal resistor is smaller, which is more conducive to the installation of the wiring harness.

[0009] In some embodiments, two opposite ends of the housing are provided with plugging slots, one end of the first conductive terminal away from the first pin is accommodated in one of the plugging slots, and the other end of the second conductive terminal away from the second pin is accommodated in the other plugging slot.

[0010] In some embodiments, locking portions are respectively provided at opposite ends of the housing, and the two locking portions are respectively located at the sides of the two plug-in slots.

[0011] In some embodiments, the locking portion is a snap-in hole provided on the outer wall of the housing, and the snap-in hole is connected to the plug-in slot.

[0012] In some embodiments, the housing is cylindrical. The housing is set to be cylindrical, which makes it easier to wrap the terminal resistor on the wiring harness, and the thickness of the wiring harness at the wrapping part is smaller.

The cross-sectional area of ​​the terminal resistor is smaller, which is more conducive to the installation of the wiring harness.

[0014] The second aspect of the present application provides a wiring harness assembly, comprising a first wiring harness, a second wiring harness and the terminal resistor provided in the first aspect of the present application. One end of the first wiring harness is electrically connected to the first conductive terminal, and one end of the second wiring harness is electrically connected to the second conductive terminal.

[0015] In some embodiments, the wiring harness assembly further comprises two connectors, wherein one connector is fixedly connected and electrically connected to one end of the first wiring harness, and the other connector is fixedly connected and electrically connected to one end of the second wiring harness. The first conductive terminal is plugged into one of the connectors to achieve electrical connection, and the second conductive terminal is plugged into the other connector to achieve electrical connection.

[0017] In some embodiments, the connector includes a positioning portion, a connecting portion and a fixing portion, wherein the fixing portion is disposed at one end of the positioning portion and the connecting portion is disposed at the other end opposite to the positioning portion. The two fixing portions are respectively fixedly connected and electrically connected to the first wiring harness and the second wiring harness, the two connecting portions are respectively electrically connected to the first conductive terminal and the second conductive terminal, and the two positioning portions are respectively fixedly connected to the two locking portions of the housing.

[0018] In some embodiments, the connecting portion includes a first clamping piece and a second clamping piece facing the first clamping piece, the first clamping piece and the second clamping piece are connected to one end of the positioning portion away from the fixing portion at an interval, and a plug-in seam is formed between the first clamping piece and the second clamping piece. When the first conductive terminal is inserted into the plug-in seam of the corresponding connecting piece, the first conductive terminal is clamped by the first clamping piece and the second clamping piece. When the second conductive terminal is inserted into the plug-in seam of the corresponding connecting piece, the second conductive terminal is clamped by the first clamping piece and the second clamping piece.

[0019] The first clamping piece and the second clamping piece are provided to clamp the first conductive terminal and the second conductive terminal respectively to achieve electrical connection, which has a simple structure, low cost and more stable electrical connection.

[0020] In some embodiments, the first clamping piece includes a first section, and the second clamping piece includes a second section. The first section and the second section are connected to an end of the positioning portion away from the fixing portion at an interval. The first section and the second section extend obliquely along the direction in which the connecting portion points to the resistor, and the interval between the first section and the second section gradually decreases.

[0021] By setting the interval between the first section and the second section to gradually decrease, when the first conductive terminal and the second conductive terminal are respectively inserted into the corresponding insertion seams, the deformation of the first section and the second section is larger, and the rebound force generated is larger, so that the first conductive terminal and the second conductive terminal are clamped tighter and the electrical connection is more stable.

[0023] In some embodiments, the connecting portion further includes a first spring sheet and a second spring sheet. The first spring sheet is disposed on a side of the first section away from the second section, and one end of the first spring sheet is connected to an end of the positioning portion away from the fixing portion. The second spring sheet is disposed on a side of the second section away from the first section, and one end of the second spring sheet is connected to an end of the positioning portion away from the fixing portion.

[0024] In some embodiments, the positioning portion is provided with an undercut, and when the connector is positioned in the corresponding insertion slot, the undercut is snapped into the corresponding snap-in hole on the housing. The connector is fixedly connected to the housing by snapping, which is convenient for assembly and improves work efficiency.

[0025] In some embodiments, the positioning portion includes a positioning surface, and the positioning surface faces the snap-fitting hole of the housing. The undercut is a spring sheet, and the undercut is convexly arranged on the positioning surface. The undercut extends obliquely along the direction from the positioning portion to the fixing portion, and the interval between the undercut and the positioning surface gradually increases. By setting the undercut as a spring sheet, the undercut is easier to be inserted into the snap-fitting hole, and the assembly is more convenient, thereby improving the work efficiency.

[0026] A third aspect of the present application provides a vehicle, comprising the wiring harness assembly provided by the second aspect of the present application.

[0027] In the terminal resistor provided in the embodiment of the present application, the first conductive terminal and the second conductive terminal are respectively connected to opposite ends of the resistor, and the first conductive terminal and the second conductive terminal are led out in opposite directions. The cross-sectional area of ​​the terminal resistor is smaller. Furthermore, when the terminal resistor is wrapped with the wiring harness, the thickness of the wiring harness at the wrapping part is smaller, which avoids the wiring harness from getting stuck during the mobile installation process, facilitates installation, and helps improve installation efficiency.

DETAILED DESCRIPTION

[0039] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Figure 2 As shown, for the convenience of description, the radial direction of the terminal resistor 300 is defined as the X-axis direction, and the axial direction (length direction) of the terminal resistor 300 is defined as the Y-axis direction.

[0040] Please refer to Figure 1 and Figure 2 The vehicle provided in the embodiment of the present application includes a wiring harness assembly 1000, and the wiring harness assembly 1000 can be used for the vehicle-mounted CAN communication device of the vehicle. The wiring harness assembly 1000 includes a first wiring harness 100, a second wiring harness 200 and a terminal resistor 300, one end of the first wiring harness 100 is electrically connected to one end of the terminal resistor 300 along the Y-axis direction, and one end of the second wiring harness 200 is electrically connected to the other end of the terminal resistor 300 along the Y-axis direction. The other end of the first wiring harness 100 and the other end of the second wiring harness 200 are both electrically connected to the wiring harness 110 in the vehicle-mounted CAN communication device to electrically connect the terminal resistor 300 to the vehicle-mounted CAN communication device. The terminal resistor 300 is mainly used to eliminate signal reflection and eliminate electromagnetic interference. The terminal resistor 300 is provided in the vehicle-mounted CAN communication device, which is conducive to improving the stability of the signal.

[0041] like Figure 1As shown, when the terminal resistor 300 is connected to the vehicle-mounted CAN communication device, it is generally necessary to wrap the terminal resistor 300 and the wiring harness 110 of the vehicle-mounted CAN communication device together, which will cause the wiring harness to become thicker at the wrapping part. If the wiring harness is too thick at the wrapping part, it will affect the mobile installation of the wiring harness, and the wiring harness will get stuck during the movement process, which is not convenient for installation.

[0042] The terminal resistor 300 provided in this application is to solve this problem. For details, please refer to Figure 3 , Figure 4 and Figure 5 The terminal resistor 300 includes a housing 310, a resistor 350, a first conductive terminal 360 and a second conductive terminal 370, the resistor 350 is disposed in the housing 310, the first conductive terminal 360 is at least partially disposed in the housing 310, and the second conductive terminal 370 is at least partially disposed in the housing 310.

[0043] Exemplarily, the housing 310 is cylindrical, a receiving cavity 311 is provided in the housing 310, and plug-in slots 312 are respectively provided at opposite ends of the housing 310 along the Y-axis direction, and along the Y-axis direction, one plug-in slot 312, the receiving cavity 311 and the other plug-in slot 312 are sequentially arranged and connected along the axial direction of the housing 310, and the two plug-in slots 312 respectively penetrate the opposite end surfaces of the housing 310 along the Y-axis direction. It should be noted that the Y-axis direction is parallel to the axial direction of the housing 310, and the X-axis direction is parallel to the radial direction of the housing 310.

[0044] The resistor 350 includes a resistor body 351 and a first pin 352 and a second pin 353 located at opposite ends thereof. Along the Y-axis direction, the first pin 352 is arranged at one end of the resistor body 351, and the second pin 353 is arranged at the other opposite end of the resistor body 351. The resistor body 351, the first pin 352 and the second pin 353 are accommodated in the accommodating cavity 311 and fixed to the cavity side of the accommodating cavity 311.

[0045] The first conductive terminal 360 and the second conductive terminal 370 have the same structure, and both the first conductive terminal 360 and the second conductive terminal 370 are flat structures. In other embodiments, the first conductive terminal 360 and the second conductive terminal 370 can both be cylindrical structures. In addition, the structures of the first conductive terminal 360 and the second conductive terminal 370 can be different, for example, the first conductive terminal 360 is a flat structure, and the second conductive terminal 370 is a cylindrical structure.

[0046] Among them, Figure 5As shown, along the Y-axis direction, one end of the first conductive terminal 360 extends into the accommodating cavity 311 and is fixedly connected and electrically connected to the first pin 352. For example, the first conductive terminal 360 and the first pin 352 can be fixedly connected and electrically connected by means including but not limited to welding or threaded connection; the first conductive terminal 360 is oriented in the first direction ( Figure 5 The first conductive terminal 360 is led out in the positive direction of the Y axis as shown, and one end of the first conductive terminal 360 away from the first pin 352 is received in one of the insertion slots 312 .

[0047] One end of the second conductive terminal 370 extends into the accommodating cavity 311 and is fixedly connected and electrically connected to the second pin 353. For example, the second conductive terminal 370 and the second pin 353 can be fixedly connected and electrically connected by means including but not limited to welding or threaded connection; the second conductive terminal 370 is oriented in the second direction ( Figure 5 The first direction and the second direction are coaxial and opposite to each other. In other embodiments, the first direction and the second direction may not be coaxial, and the first direction and the second direction may have a certain offset.

[0048] It can be understood that in this embodiment, the first conductive terminal 360 and the second conductive terminal 370 are all disposed in the housing 310, and the insulation of the terminal resistor 300 is better. In other embodiments, the end of the first conductive terminal 360 away from the first pin 352 is located outside the housing 310, and the end of the second conductive terminal 370 away from the second pin 353 is located outside the housing 310.

[0049] Among them, one end of the first wiring harness 100 is electrically connected to the first conductive terminal 360, and the other end of the first wiring harness 100 is electrically connected to the wiring harness 110 in the vehicle-mounted CAN communication device; one end of the second wiring harness 200 is electrically connected to the second conductive terminal 370, and the other end of the second wiring harness 200 is electrically connected to the wiring harness 110 in the vehicle-mounted CAN communication device, so as to electrically connect the terminal resistor 300 to the vehicle-mounted CAN communication device.

[0050] In this embodiment, along the Y-axis direction, the first conductive terminal 360 and the second conductive terminal 370 are respectively connected to the opposite ends of the resistor 350, and the first conductive terminal 360 and the second conductive terminal 370 are led out in opposite directions. Compared with the solution in which the first conductive terminal 360 and the second conductive terminal 370 are arranged in parallel in the related art, the cross-sectional area of ​​the terminal resistor 300 cut along the X-axis direction is smaller. Furthermore, when the terminal resistor 300 and the wiring harness 110 are covered by the outer sheath 500, the thickness of the outer sheath 500 at the place where the terminal resistor 300 is covered is smaller, which avoids the wiring harness 110 from getting stuck during the movement process, facilitates installation, and is conducive to improving installation efficiency.

[0051] In this embodiment, by setting the outer shell 310 to be cylindrical, it is convenient for the outer sheath 500 to cover the terminal resistor 300 and helps to reduce the thickness of the outer sheath 500 at the portion where the terminal resistor 300 is covered.

[0052] In some embodiments, along the Y-axis direction, the first conductive terminal 360, the first pin 352, the resistor body 351, the second pin 353 and the second conductive terminal 370 are arranged in a straight line. This design makes the cross-sectional area of ​​the terminal resistor 300 cut along the X-axis direction smaller, and the thickness of the outer sheath 500 at the place where it covers the terminal resistor 300 is smaller, which is more conducive to the installation of the wiring harness 110 and has higher installation efficiency.

[0053] In some embodiments, the center line of the first conductive terminal 360, the center line of the first pin 352, the center line of the resistor body 351, the center line of the second pin 353, the center line of the second conductive terminal 370 and the axis of the housing 310 are collinear. This design makes the cross-sectional area of ​​the terminal resistor 300 smaller along the X-axis direction, and the thickness of the outer sheath 500 at the location where the terminal resistor 300 is covered is smaller, which is more conducive to the installation of the wiring harness 110 and has higher installation efficiency.

[0054] In some embodiments, please refer to Figure 3 , Figure 6 and Figure 7 The wiring harness assembly 1000 further includes two connectors 400. One end of one of the connectors 400 is fixedly connected and electrically connected to one end of the first wiring harness 100 by means including but not limited to welding, and the other end is inserted into the corresponding plug-in slot 312 and plugged into the first conductive terminal 360. It can be understood that the first conductive terminal 360 is plugged into one of the connectors 400 to achieve electrical connection.

[0055] One end of the other connector 400 is fixedly connected and electrically connected to one end of the second wiring harness 200 by means including but not limited to welding, and the other end is inserted into the corresponding plug slot 312 and plugged into the second conductive terminal 370. It can be understood that the second conductive terminal 370 is plugged into the other connector 400 to achieve electrical connection.

[0056] In this embodiment, the first wiring harness 100 and the second wiring harness 200 are respectively plugged with the first conductive terminal 360 and the second conductive terminal 370 through two connectors 400 to achieve electrical connection between the first wiring harness 100 and the second wiring harness 200 and the resistor 350, which is convenient for assembly and has higher assembly efficiency. After the two connectors 400 are respectively plugged with the first conductive terminal 360 and the second conductive terminal 370, the two connectors 400 are fixedly connected to the housing 310 to ensure that the two connectors 400 can be stably plugged with the first conductive terminal 360 and the second conductive terminal 370, respectively, thereby improving the stability of the electrical connection.

[0057] For further information, please refer to Figure 5 , Figure 6 and Figure 7 , along the Y-axis direction, the opposite ends of the housing 310 are provided with locking portions 314, and the two locking portions 314 are respectively located at the sides of the two plug-in slots 312. The connector 400 includes a fixing portion 401, a positioning portion 402 and a connecting portion 403. Along the Y-axis direction, the fixing portion 401 is arranged at one end of the positioning portion 402, and the connecting portion 403 is arranged at the other end opposite to the positioning portion 402. Among them, the fixing portions 401 of the two connectors 400 are respectively fixedly connected and electrically connected to the first wiring harness 100 and the second wiring harness 200. The connecting portions 403 of the two connectors 400 are respectively plugged with the first conductive terminal 360 and the second conductive terminal 370, which can also be understood as that the connecting portions 403 of the two connectors 400 are respectively fixedly connected and electrically connected to the first conductive terminal 360 and the second conductive terminal 370. The positioning portions 402 of the two connectors 400 are respectively fixedly connected to the two locking portions 314.

[0058] Among them, please refer to Figure 6 , Figure 7 , Figure 8 and Fig. 9 The connecting portion 403 includes a first clamping piece 404 and a second clamping piece 405 facing the first clamping piece 404. The first clamping piece 404 and the second clamping piece 405 are connected to one end of the positioning portion 402 away from the fixing portion 401 at intervals, and a plug-in seam 406 is formed between the first clamping piece 404 and the second clamping piece 405. When the first conductive terminal 360 is plugged into the corresponding connecting member 400, the first conductive terminal 360 is inserted into the plug-in seam 406 of the connecting member 400, and the first conductive terminal 360 is clamped by the first clamping piece 404 and the second clamping piece 405, so as to achieve fixed connection and electrical connection between the connecting portion 403 and the first conductive terminal 360, and further achieve electrical connection between the first wiring harness 100 and the resistor 350.

[0059] When the second conductive terminal 370 is plugged into the corresponding connector 400, the second conductive terminal 370 is inserted into the plug-in seam 406 of the connector 400, and the second conductive terminal 370 is clamped by the first clamping piece 404 and the second clamping piece 405 to achieve a fixed connection and electrical connection between the connecting part 403 and the second conductive terminal 370, thereby achieving an electrical connection between the second wiring harness 200 and the resistor 350.

[0060] In this embodiment, the first clamping piece 404 and the second clamping piece 405 are provided to realize the electrical connection between the first wire harness 100 and the resistor 350 and the electrical connection between the second wire harness 200 and the resistor 350. This design has a simple structure, low cost, and more stable electrical connection.

[0061] For further information, please refer to Figure 7 , Figure 8 and Fig. 9 , the first clamping piece 404 includes a first section 407, and the second clamping piece 405 includes a second section 408. Along the Y-axis direction, the first section 407 and the second section 408 are both connected to the end of the positioning portion 402 away from the fixing portion 401, and along the X-axis direction, the first section 407 and the second section 408 are spaced and face each other. The first section 407 and the second section 408 are respectively along the direction of the connection portion 403 pointing to the resistor 350 ( Figure 8 The negative Y direction shown or Fig. 9 The first section 407 and the second section 408 extend obliquely (in the positive direction of the Y axis as shown), and the interval between the first section 407 and the second section 408 gradually decreases.

[0062] The first conductive terminal 360 includes a first clamped portion 361, which is a portion of the first conductive terminal 360 that abuts against the first clamping piece 404 and the second clamping piece 405. The dimension of the first clamped portion 361 along the X-axis direction is greater than the minimum interval between the first section 407 and the second section 408. When the first conductive terminal 360 is inserted into the corresponding insertion seam 406, the first clamped portion 361 abuts against the first section 407 and the second section 408 on both sides along the X-axis direction.

[0063] Among them, since the size of the first clamped portion 361 along the X-axis direction is larger than the minimum interval between the first section 407 and the second section 408, when the first clamped portion 361 abuts against the first section 407 and the second section 408, the first section 407 and the second section 408 are elastically deformed in the direction away from the first clamped portion 361 respectively, and the deformed first section 407 and the second section 408 will generate a rebound force, and the first section 407 and the second section 408 both have a tendency to rebound toward the first clamped portion 361, so that the first section 407 and the second section 408 can clamp the first clamped portion 361 to achieve a fixed connection and electrical connection between the connecting portion 403 and the first conductive terminal 360, thereby achieving an electrical connection between the first wiring harness 100 and the resistor 350.

[0064] In this embodiment, the interval between the first section 407 and the second section 408 is gradually reduced, that is, the first section 407 and the second section 408 are inclined. Compared with the design scheme in which the first section 407 and the second section 408 are parallel to each other, when the first clamped portion 361 abuts against the first section 407 and the second section 408, the first section 407 and the second section 408 undergo elastic deformation of a larger amount, so that the first section 407 and the second section 408 generate a larger rebound force, the first clamped portion 361 is clamped more tightly, and the electrical connection is more stable.

[0065] In this embodiment, the second conductive terminal 370 has the same structure as the first conductive terminal 360. The second conductive terminal 370 includes a second clamped portion 371. The matching relationship between the second clamped portion 371 and the corresponding first section 407 and second section 408 can refer to the relevant description of the first conductive terminal 360 and Fig. 9 , no more details.

[0066] Optional, please refer to Figure 7 , Figure 8 and Fig. 9 The first clamping piece 404 further includes a third section 409, which is connected to one end of the first section 407 away from the positioning portion 402. The second clamping piece 405 further includes a fourth section 410, which is connected to one end of the second section 408 away from the positioning portion 402. Along the X-axis direction, the third section 409 and the fourth section 410 are arranged opposite to each other, and the interval between the first section 407 and the second section 408 and the interval between the third section 409 and the fourth section 410 constitute the insertion seam 406.

[0067] The third section 409 and the fourth section 410 are respectively directed along the direction of the connection portion 403 to the resistor 350 ( Figure 8 The negative Y direction shown or Fig. 9 The third section 409 and the fourth section 410 are inclined and extend in the positive direction of the Y axis as shown, and the interval between the third section 409 and the fourth section 410 gradually increases. The maximum interval between the third section 409 and the fourth section 410 is greater than the dimension of the end of the first conductive terminal 360 away from the resistor 350 along the X axis direction, and the maximum interval between the third section 409 and the fourth section 410 is greater than the dimension of the end of the second conductive terminal 370 away from the resistor 350 along the X axis direction. In this embodiment, the third section 409 and the fourth section 410 play a guiding role, which facilitates the first conductive terminal 360 and the second conductive terminal 370 to be respectively inserted into the corresponding insertion seam 406.

[0068] In some embodiments, please refer to Figure 7 , Figure 8 and Fig. 9, along the direction from the resistor 350 to the connection portion 403, the size of the end of the first conductive terminal 360 away from the resistor 350 along the X-axis direction gradually decreases, and the size of the end of the second conductive terminal 370 away from the resistor 350 along the X-axis direction gradually decreases. The end of the first conductive terminal 360 away from the resistor 350 and the end of the second conductive terminal 370 away from the resistor 350 can play a guiding role, facilitating the first conductive terminal 360 and the second conductive terminal 370 to be respectively inserted into the corresponding insertion seam 406.

[0069] In some embodiments, please refer to Figure 7 , Figure 8 and Fig. 9 The connecting portion 403 further includes a first elastic piece 411 and a second elastic piece 412. The first elastic piece 411 is disposed on one side of the first section 407, and one end of the first elastic piece 411 is connected to one end of the positioning portion 402 away from the fixing portion 401. The second elastic piece 412 is disposed on one side of the second section 408, and one end of the second elastic piece 412 is connected to one end of the positioning portion 402 away from the fixing portion 401.

[0070] Specifically, the first spring piece 411 is disposed on a side of the first section 407 away from the second section 408, and the first spring piece 411 is spaced apart from the first section 407. In other embodiments, the first spring piece 411 may also be disposed in close contact with the first section 407. The second spring piece 412 is disposed on a side of the second section 408 away from the first section 407, and the second spring piece 412 is spaced apart from the second section 408. In other embodiments, the second spring piece 412 may also be disposed in close contact with the second section 408.

[0071] In this embodiment, when the first conductive terminal 360 is inserted into the corresponding insertion seam 406, when the first section 407 and the second section 408 are elastically deformed, the first section 407 and the second section 408 respectively abut against the first elastic sheet 411 and the second elastic sheet 412, and the first elastic sheet 411 will be elastically deformed in a direction away from the first section 407, and the second elastic sheet 412 will be elastically deformed in a direction away from the second section 408. The deformed first elastic sheet 411 and the second elastic sheet 412 will both generate a rebound force, and the two rebound forces act on the first clamped portion 361 through the first section 407 and the second section 408 respectively, so that the first clamped portion 361 is subjected to a greater rebound force, and the first clamped portion 361 is clamped more tightly, thereby improving the stability of the electrical connection between the connector 400 and the first conductive terminal 360.

[0072] In this embodiment, the matching relationship between the second conductive terminal 370 and the corresponding first elastic sheet 411 and second elastic sheet 412 can refer to the related description of the first conductive terminal 360 and will not be described in detail.

[0073] In some embodiments, please refer to Figure 7, Figure 8 and Fig. 9 The locking portion 314 is a snap-in hole 315 provided on the outer wall of the housing 310, and the snap-in hole 315 is connected to the plug-in slot 312. Specifically, the locking portion 314 is two snap-in holes 315 provided on the outer wall of the housing 310, such as Figure 8 As shown, along the X-axis direction, the two engaging holes 315 are arranged opposite to each other at intervals, and the two engaging holes 315 penetrate the slot side surfaces of the inserting slot 312 , so that the two engaging holes 315 are connected to the two inserting slots 312 respectively.

[0074] Continue to refer Figure 7 , Figure 8 and Fig. 9 , the positioning portion 402 is provided with an undercut 413, specifically, the number of the undercut 413 is two. The positioning portion 402 includes two positioning surfaces 414, and along the X-axis direction, the two positioning surfaces 414 are arranged opposite to each other, and the two positioning surfaces 414 are respectively facing the two snap-fit ​​holes 315 of the housing 310. The two undercuts 413 are respectively convexly arranged on the two positioning surfaces 414. When the connector 400 is positioned in the corresponding plug-in slot 312, the two undercuts 413 are respectively snapped into the two snap-fit ​​holes 315 on the housing 310 to achieve a fixed connection between the positioning portion 402 and the locking portion 314, and then the connector 400 can be fixedly connected to the housing 310.

[0075] It can be understood that in this embodiment, the two connectors 400 are fixedly connected to the housing 310 by means of a snap-fitting manner, which facilitates assembly and thus improves assembly efficiency.

[0076] In other embodiments, Figure 8 and Fig. 9 As shown, the snap-in hole 315 penetrates the slot side of the plug-in slot 312 and the outer peripheral surface of the housing 310, that is, the snap-in hole 315 connects the plug-in slot 312 with the outside. When removing the connector 400, a snap-in pin can be used to insert the snap-in hole 315 from the outer peripheral surface of the housing 310, and the undercut 413 can be pushed out of the snap-in hole 315, and finally the connector 400 can be pulled out from the plug-in slot 312, which is convenient for removal.

[0077] For further information, please refer to Figure 7 , Figure 8 and Fig. 9 The undercut 413 is a spring, and the undercut 413 points along the direction of the positioning portion 402 to the fixing portion 401 ( Figure 8 The positive direction of the Y axis or Fig. 9 The distance between the undercut 413 and the positioning surface 414 gradually increases. Figure 8 and Fig. 9As shown, the two undercuts 413 of the positioning portion 402 abut against the slot side of the insertion slot 312 and move toward the two clamping holes 315. During the movement, the two undercuts 413 are elastically deformed toward the two positioning surfaces 414. When the two undercuts 413 move to the two clamping holes 315, the two undercuts 413 rebound and are respectively clamped into the two clamping holes 315.

[0078] In this embodiment, by configuring the undercut 413 as a spring sheet, the undercut 413 can be more easily inserted into the engaging hole 315 , which facilitates assembly and improves assembly efficiency.

[0079] In some embodiments, please refer to Figure 6 and Figure 7 The positioning portion 402 is in a square shape, and correspondingly, the insertion slot includes a square segment 313, the outline of the square segment 313 is the same as the outer contour of the positioning portion 402, and when the connector 400 is inserted into the insertion slot 312, the positioning portion 402 is located in the square segment 313. In this embodiment, by setting the positioning portion 402 in a square shape, the connector 400 is prevented from rotating relative to the housing 310, thereby ensuring the stability of the connection between the two connectors 400 and the first conductive terminal 360 and the second conductive terminal 370, thereby ensuring the stability of the electrical connection.

[0080] In some embodiments, the first conductive terminal 360, the resistor 350, the second conductive terminal 370 and the housing 310 are integrally injection molded. Specifically, the first conductive terminal 360, the resistor 350 and the second conductive terminal 370 are first assembled into one, and then the assembled first conductive terminal 360, the resistor 350 and the second conductive terminal 370 are placed in a mold and injection molded together with the housing 310. After the housing 310 is formed, the first conductive terminal 360, the resistor 350 and the second conductive terminal 370 are fixed in the accommodating cavity 311. In this embodiment, the first conductive terminal 360, the resistor 350, the second conductive terminal 370 and the housing 310 are integrally injection molded, thereby reducing the assembly process and improving the work efficiency.
