Description

Technical Field

[0001] The present application relates to the technical field of wiring harness connection, and in particular to a housing device, a connector and a vehicle. Background Art

[0002] Connectors are widely used in the automotive industry as devices for connecting wiring harnesses. Generally, connectors are used in pairs, which are called male connectors and female connectors. Male connectors generally include plug-in terminals, and female connectors generally include terminals. When two electrical components need to be connected, the plug-in terminal is connected to one of the electrical components, the terminal is connected to the other electrical component, and then the plug-in terminal and the terminal are plugged together to achieve electrical connection between the two electrical components.

[0003] In the connector provided by the related art, the terminal position assurance member is provided with a buckle. When the terminal position assurance member is assembled with the sheath, the buckle is inserted into the locking groove in the sheath by hard interference to achieve a buckle fit. When the terminal position assurance member and the sheath are disassembled, a tool is inserted into the interior of the terminal position assurance member, and the terminal position assurance member is pried out from the sheath. Since the buckle on the terminal position assurance member has no elasticity, it is forcibly inserted into the sheath during assembly and locked with the buckle in the sheath. When it is forcibly pulled out of the sheath during disassembly, the buckle is easily worn and deformed, resulting in the plugging and unplugging force of the terminal position assurance member relative to the sheath to change accordingly, and cannot reach the standard range. Over time, there is a risk that the terminal position assurance member will fall off from the sheath. Utility Model Content

[0026] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0027] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0028] Connectors are generally used in pairs, and the connectors used in pairs are respectively called the first connector and the second connector. The first connector includes a female terminal, and the second connector includes a male terminal. When in use, the female terminal is connected to the first wiring harness, and the male terminal is connected to the second wiring harness. The male terminal and the female terminal are plugged together to achieve the connection between the first connector and the second connector, thereby achieving the connection between the first wiring harness and the second wiring harness.

[0029] The embodiment of the present application provides a vehicle, which includes a mechanism housing and a connector. The mechanism housing includes a metal bracket, fasteners, etc., and the mechanism housing plays a role of supporting, resisting mechanical shock, and resisting mechanical vibration. The mechanism housing includes an inner cavity, and the inner cavity is used to install multiple electrical components and a connector, and the connector is used to connect two electrical components. A first wiring harness connects a first electrical component, and a second wiring harness connects a second electrical component. The connection between the first connector and the second connector is achieved by plugging the first connector and the second connector.

[0030] For example, the first electrical device may be a power supply, and the second electrical device may be a vehicle controller. The first connector and the second connector are plugged together so that the power supply supplies power to the vehicle controller. When it is necessary to replace the battery or overhaul the vehicle, the first connector and the second connector may be separated to facilitate replacement of the battery or overhaul of the vehicle.

[0031] The first electrical device may also be an external charging device, and the second electrical device may be a power source of the vehicle. By plugging the first connector and the second connector, the external charging device may charge the power source of the vehicle. When the power source of the vehicle reaches the target power, the first connector and the second connector may be separated to end charging the power source of the vehicle.

[0032] The first electrical device may also be a vehicle controller, and the second electrical device may be a central control display screen or an audio device, etc., and the vehicle controller may control the central control display screen or an audio device, etc., by plugging the first connector and the second connector. When the device needs to be replaced or repaired, the first connector and the second connector may be separated to facilitate replacement or repair of the device. The first electrical device and the second electrical device may also be other devices, as long as the first electrical device and the second electrical device are connected by plugging two connectors, and the embodiments of the present application are not limited thereto.

[0033] The present application provides a connector, which can be used as the first connector or the second connector. In the embodiment of the present application, the connector is taken as the first connector, that is, the connector includes a female terminal, and the connector is described in detail.

[0034] See also Figures 1 to 3 , Figure 1 This is a schematic diagram of a three-dimensional structure of a connector according to an embodiment of the present application. For ease of description, the Y-axis direction is defined as the length direction of the connector, the X-axis direction is defined as the width direction of the connector, and the Z-axis direction is defined as the thickness direction of the connector. The X-axis, Y-axis, and Z-axis are perpendicular to each other.

[0035] The connector includes a housing device and a connecting terminal 200, and the housing device includes a body 100 and a terminal position guarantee member 300. The connecting terminal 200 is installed inside the body 100, and the body 100 provides a primary locking for the connecting terminal 200. The terminal position guarantee member 300 is installed inside the body 100, and the terminal position guarantee member 300 provides a secondary locking for the connecting terminal 200, thereby generating a greater locking force while ensuring that the connecting terminal 200 remains in the body 100, preventing the connecting terminal 200 from being loosened from the body 100.

[0036] The connection terminal 200 includes a clamping body 210 and a plugging body 220 which are sequentially connected and fixed along the Z-axis direction. The clamping body 210 is used to connect the wire harness 400 , and the plugging body 220 and the clamping body 210 are plugged into the body 100 together.

[0037] The wiring harness 400 includes a conductive inner core 410 and an insulating coating 420, and the clamping body 210 includes a first clamping section 211 and a second clamping section 212, wherein the first clamping section 211 is used to clamp the conductive inner core 410 of the wiring harness 400, and the second clamping section 212 is used to clamp the insulating coating 420 of the wiring harness 400. The conductive inner core 410 is generally made of copper or other conductive materials, and the insulating coating 420 is generally made of rubber, and the insulating coating 420 is coated on the conductive inner core 410, so that the conductive inner core 410 is insulated from the outside. When the wiring harness 400 is connected to the snap-on body 210 of the connecting terminal 200, the wiring harness 400 needs to peel off a section of the insulating coating 420, and the conductive core 410 of the wiring harness 400 is exposed outside the insulating coating 420, so that the first snap-on section 211 is in direct contact with the conductive core 410, so that the connecting terminal 200 and the wiring harness 400 are electrically connected.

[0038] The plug-in body 220 is a rectangular frame, and the plug-in body 220 includes a first peripheral wall 221, a second peripheral wall 222 and two side walls, wherein the two side walls are respectively a first side wall 223 and a second side wall 224, and the first peripheral wall 221, the first side wall 223, the second peripheral wall 222 and the second side wall 224 are connected end to end to form a rectangular frame. Among them, the first peripheral wall 221 and the second peripheral wall 222 are opposite to each other along the Z-axis direction, and the first side wall 223 and the second side wall 224 are opposite to each other along the X-axis direction. The first side wall 223 and the second side wall 224 are both perpendicular to the first peripheral wall 221, and the second peripheral wall 222 and the first peripheral wall 221 are parallel to each other, thereby making the shape of the plug-in body 220 a regular rectangular parallelepiped.

[0039] The main body 100 is in a rectangular parallelepiped shape, and includes a main body top surface 101 and a main body bottom surface 102 opposite to each other along the Z axis direction, and includes a first end surface 103 and a second end surface 104 opposite to each other along the Y axis direction, and a first side surface 105 and a second side surface 106 opposite to each other along the X axis direction.

[0040] The main body 100 is provided with a channel 107 , which is provided on the top surface 101 of the main body and extends in the Z-axis direction. The channel 107 encloses a rectangular hole. The shape of the plug-in body 220 is a regular rectangular parallelepiped, which facilitates the insertion of the plug-in body 220 into the channel 107 .

[0041] The connection terminal 200 further includes a locking member 201, one end of which is connected to the outer wall surface of the first peripheral wall 221, and the end of the locking member 201 is away from the outer wall surface of the first peripheral wall 221 and extends along the Z-axis direction. Figure 2 and Figure 3 , the inner wall surface of the channel 107 is concavely provided with a step groove 1071, and the diameter of the step groove 1071 in the X-axis direction is larger than the diameter of the channel 107 in the X-axis direction. When the connecting terminal 200 is inserted into the channel 107 of the main body 100, the inner wall surface of the channel 107 abuts against the locking member 201, so that the locking member 201 undergoes elastic deformation, and the end of the locking member 201 approaches the outer wall surface of the first peripheral wall 221, until the locking member 201 is locked to the step groove 1071 through elastic deformation, and the end of the locking member 201 is away from the outer wall surface of the first peripheral wall 221 and abuts against the step surface of the step groove 1071, and the connecting terminal 200 cannot move along the positive direction of the Z axis. In addition, one end of the plug-in body 220 away from the clamping body 210 abuts against the bottom surface of the channel 107, and the connecting terminal 200 cannot move along the negative direction of the Z axis, so that the connecting terminal 200 and the main body 100 are locked.

[0042] In this embodiment, the connection terminal 200 includes two locking pieces 201, and the two locking pieces 201 are respectively connected to the outer wall surface of the first peripheral wall 221 and the outer wall surface of the second peripheral wall 222. The channel 107 is recessed with two step grooves 1071, and the two step grooves 1071 are respectively opened on different inner wall surfaces of the channel 107, and the two step grooves 1071 are opposite to each other along the X-axis direction. In this way, the connection terminal 200 is locked more firmly relative to the body 100. In other examples, the first side wall 223 and / or the second side wall 224 can also be connected to the locking piece 201, or a plurality of locking pieces 201 can be connected to one of the outer walls of the plug-in body 220, and the inner wall surface of the channel 107 is recessed with a step groove 1071 corresponding to the locking piece 201, so that the connection terminal 200 and the body 100 are locked.

[0043] The main body 100 is provided with a plurality of channels 107 , and the plurality of channels 107 are all provided on the top surface 101 of the main body, and the plurality of channels 107 extend in the Z-axis direction. Specifically in this embodiment, the number of channels 107 is 10, and the 10 channels 107 are arranged in two rows along the Y-axis direction, and each row is provided with 5 channels 107 .

[0044] In some embodiments, see Figure 4 and Figure 5The terminal position guarantee member 300 includes a first connecting arm 310, one end of which is provided with a first elastic force arm 312 and a first slot 311, and along the thickness direction of the terminal position guarantee member 300, the first elastic force arm 312 and the first slot 311 are opposite; a first buckle 313 is convexly provided on the side of the first connecting arm 310 away from the first slot 311. The body 100 is provided with a first plug hole 110, and the inner wall surface of the first plug hole 110 is concavely provided with a first locking groove (not shown in the figure) along the positive direction of the Z axis. When the first elastic force arm 312 is inserted into the first plug hole 110, the body 100 abuts against the first buckle 313, that is, the inner wall surface of the first plug hole 110 abuts against the first buckle 313, and the first buckle 313 is subjected to the extrusion force from the body 100 along the negative direction of the Z axis. The first buckle 313 pushes the first elastic force arm 312 along the negative direction of the Z axis, the first elastic force arm 312 is elastically deformed, and the first connecting arm 310 is deformed in the negative direction of the Z axis. The first locking groove has a certain space, the first elastic force arm 312 has a tendency to restore the natural state, the first elastic force arm 312 pushes the first buckle 313 along the positive direction of the Z axis to provide the first buckle 313 with a force along the positive direction of the Z axis, so that the first buckle 313 moves along the positive direction of the Z axis, and then the first buckle 313 is engaged in the first locking groove.

[0045] Along the thickness direction of the terminal position assurance member 300, the thickness of the first elastic force arm 312 is less than the thickness of the first connecting arm 310, so that the first elastic force arm 312 and the first connecting arm 310 enclose the first slot 311. Specifically in this embodiment, the first connecting arm 310 includes two side surfaces opposite to each other along the X-axis direction, and the two side surfaces are respectively recessed along the X-axis direction to form two first slots 311, and the two first slots 311 are opposite to each other along the X-axis direction, and the distance between the bottom surfaces of the two first slots 311 along the X-axis direction is less than the distance between the two side surfaces of the first connecting arm 310 along the X-axis direction. Therefore, the first connecting arm 310 is prone to elastic deformation at the first slot 311. The first elastic force arm 312 refers to the portion of the first connecting arm 310 that is prone to elastic deformation.

[0046] In other embodiments, one side surface of the first connecting arm 310 is recessed along the X-axis direction to form a first slot 311, the bottom surface of the first slot 311 is opposite to the other side surface of the first connecting arm 310, and the distance between the bottom surface of the first slot 311 and the other side surface of the first connecting arm 310 along the X-axis direction is smaller than the distance between the two side surfaces of the first connecting arm 310 along the X-axis direction. Therefore, the first connecting arm 310 is also prone to elastic deformation at the first slot 311.

[0047] The first buckle 313 is wedge-shaped, and includes three side faces, an inclined surface, and an end face. Two side faces of the first buckle 313 are opposite to each other along the X-axis direction, and the other side face is opposite to the inclined surface along the Y-axis direction. The end face of the first buckle 313 faces away from the first connecting arm 310, and the end face of the first buckle 313 is parallel to the XOY plane. The inclined surface of the first buckle 313 has an angle relative to the XOY plane. The wedge shape of the first buckle 313 can prevent the first buckle from being easily worn and deformed. The side face opposite to the inclined surface in the Y-axis direction abuts against the inner wall surface of the first locking groove, so that the first buckle 313 is clamped in the first locking groove, thereby installing the terminal position assurance member 300 in the body 100.

[0048] In other examples, the first buckle 313 may be a triangle, a cuboid, or other suitable shapes, which are not limited here.

[0049] The terminal position guarantee member 300 is assembled to the body 100 by elastic deformation of the first elastic force arm 312 so that the first buckle 313 is engaged in the first locking groove. The first elastic force arm 312 bears the extrusion force of the body 100 through elastic deformation, and the size of the first buckle 313 only changes slightly, so that the first buckle 313 is not easy to wear and deform. The plug-in and pull-out force of the terminal position guarantee member relative to the body is within a preset range, which does not affect the plug-in and pull-out force of the terminal position guarantee member during assembly, and prevents the terminal position guarantee member from falling off from the body. The channel 107 is connected to the first jack 110, and the opening of the channel 107 and the opening of the first jack 110 are respectively located on the adjacent two sides of the body 100. The channel 107 is opened on the top surface 101 of the body along the Z-axis direction, and the first jack 110 is opened on the second end surface 104 along the Y-axis direction. The channel 107 is used for the connection terminal 200 to be inserted, and the first plug hole 110 is used for the first connection arm 310 to be inserted. The first buckle 313 of the first connection arm 310 can limit the terminal position assurance member 300 from moving along the positive direction of the Y axis.

[0050] In some embodiments, continue to refer to Figure 5 The terminal position ensuring member 300 also includes a second connecting arm 320. The second connecting arm 320 and the first connecting arm 310 are spaced apart and opposite to each other along the width direction of the terminal position ensuring member 300. A second elastic force arm 322 and a second slot 321 are provided at one end of the second connecting arm 320. Along the thickness direction of the terminal position ensuring member 300, the second elastic force arm 322 and the second slot 321 are opposite to each other; the side wall of the second connecting arm 320 is recessed with a second slot 321, and a second buckle 323 is convexly provided on the side of the second elastic force arm 322 away from the second slot 321.

[0051] The body 100 is further provided with a second insertion hole 120 , which is spaced apart from the first insertion hole 110 along the width direction of the body 100 , and the inner wall surface of the second insertion hole 120 is provided with a second locking groove (not shown in the figure) along the positive direction of the Z axis.

[0052] When the second elastic force arm 322 is inserted into the second insertion hole 120, the body 100 abuts against the second buckle 323, that is, the inner wall surface of the second insertion hole 120 abuts against the second buckle 323, and the second buckle 323 is subjected to the extrusion force from the body 100 along the negative direction of the Z axis. The second buckle 323 pushes the second elastic force arm 322 along the negative direction of the Z axis, and the second elastic force arm 322 undergoes elastic deformation, and the second elastic force arm 322 deforms in the negative direction of the Z axis. The second locking groove has a certain space, and the second elastic force arm 322 has a tendency to restore the natural state. The second elastic force arm 322 pushes the second buckle 323 along the positive direction of the Z axis to provide the second buckle 323 with a force along the positive direction of the Z axis, so that the second buckle 323 moves along the positive direction of the Z axis, and then the second buckle 323 is engaged in the first locking groove.

[0053] The terminal position ensuring member includes a first elastic force arm 312 and a second elastic force arm 322 , which can increase the locking force of the terminal position ensuring member 300 relative to the body 100 .

[0054] Specifically in this embodiment, the second connecting arm 320 includes two outer side surfaces opposite to each other along the X-axis direction, and the two outer side surfaces are respectively recessed along the X-axis direction to form two second slots 321, and the two second slots 321 are opposite to each other along the X-axis direction, and the distance between the bottom surfaces of the two second slots 321 along the X-axis direction is smaller than the distance between the two outer side surfaces of the second connecting arm 320 along the X-axis direction. Therefore, the second connecting arm 320 is prone to elastic deformation at the second slots 321. The second elastic force arm 322 refers to the part of the second connecting arm 320 that is prone to elastic deformation.

[0055] In other embodiments, one of the outer side surfaces of the second connecting arm 320 is recessed along the X-axis direction to form a second slot 321, the bottom surface of the second slot 321 is opposite to the other outer side surface of the second connecting arm 320, and the distance between the bottom surface of the second slot 321 and the other outer side surface of the second connecting arm 320 along the X-axis direction is smaller than the distance between the two outer side surfaces of the second connecting arm 320 along the X-axis direction. Therefore, the second connecting arm 320 is also prone to elastic deformation at the second slot 321.

[0056] The second buckle 323 is wedge-shaped, and includes three side faces, an inclined surface, and an end face. Two side faces of the second buckle 323 are opposite to each other along the X-axis, and the other side face is opposite to the inclined surface along the Y-axis direction. The end face of the second buckle 323 faces away from the second connecting arm 320, and the end face of the second buckle 323 is parallel to the XOY plane. The inclined surface of the second buckle 323 is at an angle to the XOY plane. The wedge-shaped second buckle 323 can prevent the second buckle 323 from being easily worn and deformed. The side face opposite to the inclined surface in the Y-axis direction abuts against the inner wall surface of the second locking groove, so that the second buckle 323 is clamped in the second locking groove, thereby installing the terminal position assurance member 300 in the body 100.

[0057] In other examples, the second buckle 323 may be in a triangular shape, a rectangular shape, or other suitable shapes, which are not limited here.

[0058] In some embodiments, the terminal position assurance member 300 also includes a connecting rib 330, which is connected between the first elastic force arm 312 and the second elastic force arm 322; the main body 100 also includes a push plate 130, and the main body 100 is provided with a plug-in space, and the push plate 130 is fixed in the plug-in space to divide the plug-in space into a first socket 110 and a second socket 120, that is, the push plate 130 is located between the first socket 110 and the second socket 120.

[0059] In some embodiments, the connecting rib 330 includes an abutting bevel 331, and the pushing plate 130 includes a mating bevel 133. The abutting bevel 331 and the mating bevel 133 are arranged at intervals, and the interval between the abutting bevel 331 and the mating bevel 133 forms a disassembly opening. The disassembly tool is inserted into the disassembly opening, and the disassembly tool pushes the abutting bevel 331, that is, the disassembly tool abuts the connecting rib 330. The connecting rib 330 is subjected to an extrusion force from the disassembly tool along the negative direction of the Z axis, so that the connecting rib 330 moves along the first slot 311 or the second slot 321. The connecting rib 330 drives the first elastic force arm 312 and the second elastic force arm 322 to move to undergo elastic deformation, the first clip 313 disengages from the first locking groove, the second clip 323 disengages from the second locking groove, the first clip 313 is unlocked from the first locking groove, the second clip 323 is unlocked from the second locking groove, and the terminal position assurance component 300 is removed from the main body 100.

[0060] When force is applied to the tool, the disassembly opening can provide movement space for the disassembly tool, which is convenient for the operator to hold the disassembly tool, and then use the lever principle to pry the connecting rib 330. The connecting rib 330 drives the first elastic force arm 312 and the second elastic force arm 322 to move to undergo elastic deformation, and the first clip 313 disengages from the first locking groove, and the second clip 323 disengages from the second locking groove.

[0061] During the disassembly process, the first elastic force arm 312 and the second elastic force arm 322 bear the force from the disassembly tool, and the first clip 313 and the second clip 323 bear less force from the disassembly tool, that is, the size of the first clip 313 and the second clip 323 is only slightly deformed, and the first clip 313 and the second clip 323 are not easy to wear and deform, and the plugging and unplugging force of the terminal position guarantee member 300 relative to the body 100 is within a preset range. In addition, it is convenient to disassemble the terminal position guarantee member 300 relative to the body 100, and it is helpful to reduce the maintenance and repair cost of the body 100.

[0062] In some embodiments, the terminal position assurance member 300 further includes a connecting plate 340 and a plurality of fixed arms, wherein the fixed arms include a first fixed arm 371 and a second fixed arm 372, the first fixed arm 371 is fixedly connected to the first connecting arm 310, and the second fixed arm 372 is fixedly connected to the second connecting arm 320. Specifically, the first fixed arm 371 and the first connecting arm 310 are fixedly connected in an L shape, the side of the first fixed arm 371 facing the negative direction of the X axis is connected to the side of the first connecting arm 310 facing the negative direction of the Z axis, the second fixed arm 372 and the second connecting arm 320 are fixedly connected in an L shape, and the side of the second fixed arm 372 facing the positive direction of the X axis is connected to the side of the first connecting arm 310 facing the negative direction of the Z axis. One end of the first fixed arm 371 close to the first buckle 313 and one end of the second fixed arm 372 close to the second buckle 323 are both connected to the same side of the connecting plate 340; the first slot 311 is between the first elastic force arm 312 and the first fixed arm 371, the second slot 321 is between the second elastic force arm 322 and the second fixed arm 372, and the connecting rib 330 and the connecting plate 340 have a movable gap in the length direction of the terminal position ensuring member.

[0063] The connecting plate 340 is provided with a movable groove 341 on one side facing the connecting rib 330, and the connecting rib 330 is spaced apart from the inner wall surface of the movable groove to form the movable gap. The movable gap provides a movable space for the connecting rib 330 to move along the Z-axis direction, and the connecting rib 330 can drive the first elastic force arm 312 and the second elastic force arm 322 to move to generate elastic deformation.

[0064] The first buckle 313 is disposed at one end of the first connecting arm 310 close to the connecting plate 340, and the second buckle 323 is disposed at one end of the second connecting arm 320 close to the connecting plate 340. With this design, the first buckle 313 and the second buckle 323 have a short pressure-bearing stroke, and the first buckle 313 and the second buckle 323 are not easily damaged when the terminal position assurance member 300 is assembled or disassembled relative to the body 100.

[0065] In some embodiments, see Figure 3 and Figure 4The push plate 130 includes a first stop portion 135, and the terminal position ensuring member 300 also includes a second stop portion 302. The second stop portion 302 is fixedly connected to the connecting plate 340. When the first connecting arm 310 is inserted into the first plug hole 110 and the second connecting arm 320 is inserted into the second plug hole 120, the first buckle 313 and the second buckle 323 can limit the movement of the connecting terminal 200 along the positive direction of the Y axis. The first stop portion 135 and the second stop portion 302 abut against each other to limit the movement of the terminal position ensuring member 300 along the insertion direction, that is, to limit the movement of the terminal position ensuring member 300 along the negative direction of the Y axis, so that the terminal position ensuring member 300 is snap-connected and locked in the main body 100.

[0066] In some embodiments, the terminal position assurance member 300 further includes a first locking arm 350 and a second locking arm 360, which are respectively connected to opposite ends of the connecting plate 340, and the first locking arm 350, the first connecting arm 310, the second connecting arm 320 and the second locking arm 360 are sequentially arranged at intervals along the width direction of the terminal position assurance member 300. The first locking arm 350 and the first connecting arm 310 cooperate to clamp the connecting terminal 200, and the second connecting arm 320 and the second locking arm 360 cooperate to clamp the connecting terminal 200. The terminal position assurance member 300 provides secondary locking for the connecting terminal 200, thereby generating a greater locking force while ensuring that the connecting terminal 200 remains in the body 100, thereby preventing the connecting terminal 200 from being loosened from the body 100.

[0067] In some embodiments, the fixed arm further includes a third fixed arm 373 and a fourth fixed arm 374, the third fixed arm 373 is fixedly connected to the first locking arm 350, and the fourth fixed arm 374 is fixedly connected to the second locking arm 360. Specifically, the third fixed arm 373 and the first locking arm 350 are fixedly connected in an L shape, the side of the third fixed arm 373 facing the positive direction of the X axis is connected to the side of the first locking arm 350 facing the negative direction of the Z axis, the fourth fixed arm 374 and the second locking arm 360 are fixedly connected in an L shape, and the side of the fourth fixed arm 374 facing the negative direction of the X axis is connected to the side of the second locking arm 360 facing the negative direction of the Z axis.

[0068] The third fixed arm 373, the fourth fixed arm 374, the first locking arm 350 and one end of the second locking arm 360 are aligned, the first locking arm 350 and the third fixed arm 373 are connected to one end of the connecting plate 340, and the second locking arm 360 and the fourth fixed arm 374 are connected to the other end of the connecting plate 340. In this way, when the connecting terminal 200 is inserted into the channel 107, the inner wall surface of the channel 107 abuts against the locking member 201, so that the locking member 201 is elastically deformed, and the end of the locking member 201 is close to the outer wall surface of the first peripheral wall 221 until the locking member 201 is locked to the step groove 1071 through elastic deformation, so that the connecting terminal 200 and the body 100 are locked, and the body 100 provides a primary locking for the connecting terminal 200. Then, when the terminal position assurance member 300 is inserted into the body 100, that is, the first locking arm 350 and the first connecting arm 310 are inserted into the first insertion hole 110, the second connecting arm 320 and the second locking arm 360 are inserted into the second insertion hole 120, the third fixed arm 373 and the first fixed arm 371 can clamp the first clamping section 211 of the connecting terminal 200, and the second fixed arm 372 and the fourth fixed arm 374 can also clamp the first clamping section 211 of the connecting terminal 200. The terminal position assurance member 300 provides secondary locking for the connecting terminal 200. Thus, a greater locking force is generated while ensuring that the connecting terminal 200 is kept in the body 100, preventing the connecting terminal 200 from being loosened from the body 100, and also preventing the terminal position assurance member 300 from shaking.

[0069] In some embodiments, see Figures 4 to 6 The first plug hole 110 includes two first trapezoidal holes 1101, the second plug hole 120 includes two second trapezoidal holes 1201, the first locking arm 350, the first connecting arm 310, the second connecting arm 320 and the second locking arm 360 are respectively inserted into the four trapezoidal holes, effectively preventing the terminal position assurance member 300 from being inserted incorrectly.

[0070] The third fixed arm 373 and the first locking arm 350 form one arm of the terminal position guarantee member 300, the first fixed arm 371 and the first connecting arm 310 form another arm of the terminal position guarantee member 300, the second fixed arm 372 and the second connecting arm 320 form another arm of the terminal position guarantee member 300, and the fourth fixed arm and the second locking arm 360 form another arm of the terminal position guarantee member 300. Each arm of the terminal position guarantee member 300 includes a plurality of reinforcing ribs 303, which can enhance the connection strength of the arm.
