This segmented design allows the connector to better achieve positioning and limiting functions during insertion. An elastic element is located inside the socket end and is positioned between the limiting section and the terminal block along a second direction.

[0020] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0021] refer to Figure 1 , Figure 1 A perspective view of a wire harness module connector provided in an embodiment of the present invention is shown.

[0022] like Figure 1 As shown, the technical solution provided in this application is a wire harness module connector, including a socket end 1, a plug end 2, and a limiting device, wherein:

[0023] Socket end 1 and plug end 2 along the first direction ( Figure 1 (As shown in the X direction) are arranged opposite to each other, the socket end 1 includes a wiring terminal 10, and the plug end 2 includes a wire harness plug 20. The wire harness plug 20 and the wiring terminal 10 are arranged correspondingly in the first direction and are used to be plugged into or separated from the wiring terminal 10.

[0024] The limiting device includes an elastic limiting component, which extends along a second direction ( Figure 1The components (shown in the Y direction) are symmetrically arranged on both sides of the wire harness plug 20, including a connector plate 3 and an elastic element. The connector plate 3 has a connecting section 30 and a limiting section 31 along the first direction. The connecting section 30 is connected to the plug end 2, and the limiting section 31 passes through the plug end 2 and the socket end 1 along the first direction. The elastic element is located inside the socket end 1 and is located between the limiting section 31 and the terminal 10 along the second direction. It is used to abut against the limiting section 31 and limit the connection when the wire harness plug 20 is plugged into the terminal 10.

[0025] This application provides a wire harness module connector. The connector plate 3 has a connecting section 30 and a limiting section 31 along a first direction. The connecting section 30 connects to the plug end 2, and the limiting section 31 passes through the plug end 2 and the socket end 1 along the first direction. This segmented design allows the connector to better achieve positioning and limiting functions during insertion. An elastic element is located inside the socket end 1 and is positioned along a second direction between the limiting section 31 and the terminal block 10. When the wire harness plug 20 is inserted into the terminal block 10, the elastic element abuts against the limiting section 31, effectively preventing accidental separation of the plug and socket after insertion and improving connection reliability. The elastic limiting component ensures a tighter fit between the plug and socket during insertion, reducing problems such as poor contact or connection detachment caused by vibration or external force.

[0026] In some embodiments, reference Figure 1 The limiting segment 31 has a limiting protrusion 32 on the side facing the terminal 10 along the second direction. The limiting protrusion 32 includes an interference segment 320 and a back pressure segment 321 along the first direction. The interference segment 320 is located near the end of the limiting segment 31 and is inclined towards the terminal 10 along the first direction. The back pressure segment 321 is located near the connecting segment 30 of the interference segment 320 and is inclined away from the terminal 10 along the first direction.

[0027] For example, the limiting protrusion 32 is divided into an interference section 320 and a back pressure section 321. This segmented design makes the limiting process more precise and reliable. During the insertion process, the interference section 320 first contacts the limiting structure of the socket end 1, playing a preliminary limiting role and preventing the plug from being over-inserted. The back pressure section 321 provides additional limiting force after the insertion is completed, ensuring that the plug and socket fit tightly and are not easy to loosen.

[0028] In some embodiments, reference Figure 1 The socket end 1 also includes a connecting plate 11, and the plug end 2 also includes a fixing plate 21. The connecting plate 11 and the fixing plate 21 are respectively disposed on opposite sides of the socket end 1 and the plug end 2 along a first direction, and both are along a third direction. Figure 1 (As shown in the Z direction). The terminal block 10 passes through the connecting plate 11 in the first direction, and the wire harness plug 20 passes through the fixing plate 21 in the first direction.

[0029] In some embodiments, reference Figure 1 The elastic element also includes a bearing plate 33, a support rod 34, a torsion spring 35, and a swing rod 36. The bearing plate 33 extends along a first direction and is located on the side of the connecting plate 11 away from the fixed plate 21 along the first direction, and is correspondingly located at the bottom of the connector plate 3. The support rod 34 is located at the top of the bearing plate 33 on the side away from the connecting plate 11 along the first direction. The swing rod 36 is located between the support rod 34 and the terminal 10 along a second direction. A stop plate 330 is provided on one side of the bearing plate 33 along the second direction, and the stop plate 330 is correspondingly provided with the support rod 34. The torsion spring 35 is sleeved on the support rod 34, and a first torsion arm 350 and a second torsion arm 351 are respectively provided on both sides along the second direction. The first torsion arm 350 abuts against the stop plate 330 for limitation, and the second torsion arm 351 abuts against the swing rod 36 for limitation.

[0030] For example, the first torsion arm 350 of the torsion spring 35 abuts against the stop plate 330 for limiting, and the second torsion arm 351 abuts against the rocker arm 36 for limiting. This multi-point limiting design makes the plug-socket connection more stable. During the insertion process, the two torsion arms of the torsion spring 35 provide limiting functions to ensure that the plug is inserted in place and is not easily loosened. The cooperation between the rocker arm 36 and the second torsion arm 351 gives the limiting function a certain degree of dynamic adjustment capability. When the plug is inserted, the rocker arm 36 will dynamically adjust its position according to the insertion depth of the plug, thereby achieving more precise limiting. This dynamic adjustment capability can adapt to different insertion forces and insertion speeds, improving the reliability of the limiting.

[0031] In some embodiments, reference Figure 1 A rotating bearing 360 is provided at the center of the swing arm 36. The bottom of the rotating bearing 360 is connected to the support plate 33, so that the swing arm 36 can swing around the rotating bearing 360. The end of the swing arm 36 away from the connecting plate 11 along the first direction abuts against the first torsion arm 350, and the end near the connecting plate 11 is provided with an arc portion 361. The arc portion 361 is bent along the second direction towards the limiting protrusion 32, so that when the wire harness plug 20 is inserted into the terminal 10, it first abuts against the interference section 320 and rebounds, and then elastically contracts and abuts against the back pressure section 321 for limiting.

[0032] For example, the design of the arc portion 361 makes the contact between the lever 36 and the limiting protrusion 32 smoother, reducing hard impacts. When the wire harness plug 20 is inserted, the arc portion 361 first abuts against the interference section 320 and rebounds, then elastically contracts and abuts against the back pressure section 321 for limiting. This staged limiting process is more precise and can effectively prevent the plug from being inserted incompletely or excessively. In addition, the design of the arc portion 361 allows the lever 36 to adapt to different insertion speeds. Whether it is a fast or slow insertion, the arc portion 361 can adapt to the insertion process through elastic contraction and rebound, ensuring a stable fit between the plug end 2 and the socket end 1.

[0033] In some embodiments, reference Figure 1 The top of the bearing plate 33 is also provided with a protrusion 37. The protrusion 37 is located on the side of the swing rod 36 facing the limiting protrusion 32 in the first direction, and is located between the torsion spring 35 and the arc portion 361 in the first direction. It is used to abut and limit the swing rod 36 when the arc portion 361 abuts against the back pressure section 321.

[0034] For example, the design of the protrusion 37 provides an additional limiting point for the lever 36. When the arcuate portion 361 abuts against the back pressure section 321, the protrusion 37 and the lever 36 abut and limit each other, forming a multiple limiting mechanism. This design further ensures that the plug will not loosen due to external force or vibration after it is inserted into place, improving the stability of the connection.

[0035] In some embodiments, reference Figure 1 The end of the connecting section 30 is provided with an adapter plate 38, which extends along a third direction and is located on the side of the fixing plate 21 away from the connecting plate 11 along a first direction, and is bolted to the fixing plate 21. Both the fixing plate 21 and the connecting plate 11 are provided with mounting holes for inserting the connector plate 3. The mounting holes extend along a second direction and are used to adjust the distance between the connector plate 3 and the wire harness plug 20.

[0036] For example, the mounting hole design allows adjustment of the distance between the connector plate 3 and the wire harness plug 20 in the second direction, thereby changing the tightness of the crimping between the connector plate 3 and the elastic element. The smaller the distance, the greater the deformation of the torsion spring 35, and the greater the resistance provided by the limiting device, thereby improving the versatility and flexibility of the connector in use.

[0037] In some embodiments, reference Figure 1The limiting device also includes a plug-in limiting component, which is disposed between the fixing plate 21 and the connecting plate 11 along a first direction, and on the side of the plug-in plate 3 away from the wire harness plug 20 along a second direction. The plug-in limiting component includes a pressure block 40 and a connecting guide rod 41, which are correspondingly disposed along the first direction. The pressure block 40 is connected to the connecting plate 11 and is used to abut against the fixing plate 21 to limit the connection when the wire harness plug 20 is plugged into the terminal block 10. The connecting guide rod 41 extends along the first direction and is connected to the fixing plate 21. Both the pressure block 40 and the connecting plate 11 are provided with mounting through holes corresponding to the connecting guide rod 41 for plugging and fixing.

[0038] For example, the insertion limiting assembly provides an additional limiting mechanism between the fixing plate 21 and the connecting plate 11. After the wire harness plug 20 is inserted into the terminal block 10, the clamping block 40 abuts against the fixing plate 21 to limit the connection, ensuring a tight fit between the plug and the socket and preventing the plug from accidentally loosening or falling off. Furthermore, the cooperation between the connecting guide rod 41 and the clamping block 40 provides stable mechanical support for the connector. The connecting guide rod 41 extends along a first direction and connects to the fixing plate 21. The clamping block 40 is inserted and fixed to the connecting guide rod 41 through a mounting through-hole, enabling the connector to maintain stable alignment and support during insertion.

[0039] In some embodiments, reference Figure 1 The limiting device also includes a snap-fit ​​limiting member, which is disposed between the fixing plate 21 and the connecting plate 11 along the first direction, and on the side of the pressure block 40 away from the wire harness plug 20 along the second direction. The snap-fit ​​limiting member includes a lower concave block 50 and an upper protrusion 51, which are matched and disposed along the first direction. The lower concave block 50 is connected to the connecting plate 11, and the upper protrusion 51 is connected to the fixing plate 21, so that when the wire harness plug 20 is plugged into the terminal block 10, the lower concave block 50 and the upper protrusion 51 are fixed in a concave-convex fit.

[0040] For example, the snap-fit ​​retainer provides an additional retaining mechanism after the harness plug 20 is inserted into the terminal block 10 through the interlocking of the lower recess 50 and the upper protrusion 51. This interlocking design ensures a tight fit between the plug and the socket, preventing accidental loosening or detachment of the plug, thereby further enhancing the connector's retaining reliability.

[0041] In some embodiments, reference Figure 1 The plug end 2 also includes a housing 22, which is disposed on the side of the fixing plate 21 away from the connecting plate 11 along the first direction, and is hollow inside. The housing 22 extends along the first direction and has an opening on the side facing the fixing plate 21. The wire harness plug 20 passes through the housing 22 along the first direction.

[0042] For example, the housing 22 provides a physical protective layer for the plug end 2, which can effectively prevent dust, moisture, debris and other contaminants from entering the plug. The combination of the housing 22 and the fixing plate 21 makes the structure of the plug end 2 more integrated, enhances the overall mechanical strength and stability, and reduces the problem of poor contact or connection failure caused by loose parts.

[0043] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
