[0024] The embodiment of the present application provides a detachable wiring harness connector to solve the disadvantage of the prior art that the wiring harness connector cannot be disassembled and assembled, resulting in the overall scrapping. It should be noted that in the present application, the direction of the disassembly tool relative to the coaxial cable is the front, front end, and front, and the opposite direction is the rear, rear end, and rear.

[0025] like Figures 1 to 7 As shown, an embodiment of the present application: a detachable wiring harness connector, comprising: a plastic outer shell 20, a plastic inner shell 10, a terminal 60, and a coaxial cable 50. The plastic outer shell 20 is provided with a plastic inner shell 10, and the plastic inner shell 10 includes a plurality of plug-in parts 101, each of which is provided with a terminal 60 and a coaxial cable 50 riveted to the inside of the terminal, and each of the plug-in parts 101 is provided with at least one pair of limiting parts, and the terminal 60 includes a double-layer plate-like end 603, a transition part 602 extending from the other end of the plate-like end 603, and an accommodating part 601 extending from the other end of the transition part 602, and elastic stop parts 6020 are further provided on the upper and lower sides of the transition part 602, and the elastic stop part 6020 abuts against a partial end face of the limiting part, and the elastic stop part 6020 and the side wall where the limiting part is located form a release space that can accommodate a disassembly tool.

[0026] By providing an elastic locking portion 6020 on the terminal and a limiting portion inside the plastic inner shell 10, when the terminal 60 is inserted into the plastic inner shell 10, the elastic locking portion 6020 is locked on the end face of the limiting portion, and a release space 105 is left between the locking end and the side wall of the plastic inner shell 10. The disassembly tool 80 can be inserted into the release space 105, and the plug-in end 801 can be used to squeeze the elastic locking portion 6020 until its two ends are placed between the two opposite limiting portions. The coaxial cable 50 can be pulled to realize the detachable performance of the terminal 60, the coaxial cable 50 and the plastic inner shell 10.

[0027] like Figure 7 As shown, it is a schematic diagram of the structure of a disassembly tool 80 in this embodiment, which includes a holding portion 802 and two plug-in ends 801 that branch off from one end of the holding portion 802 and extend toward the distal end. The plug-in ends 801 extend into the release space 105 and are used to squeeze the elastic locking portion 6020 to move inward, thereby detaching the terminal 60 and the coaxial cable 50 from the plastic inner shell 10.

[0028] like Figure 5 As shown, specifically, the limiting portion includes a first limiting portion 103 horizontally placed on the left and right side walls of the plug-in portion 101 and a second limiting portion 104 located on the upper and lower side walls of the plug-in portion 101. After the plate-like end 603 of the terminal 60 passes through the first limiting portion 103, the elastic locking portion 6020 abuts against the partial end surface 1040 of the second limiting portion 104 facing the first limiting portion 103.

[0029] Reference Figure 6 , the width of the accommodating portion 601 is greater than the width of the transition portion 602. The accommodating portion 601 is a semi-enclosed open structure, and the two side end walls of the open structure are clamped on the inner surface of the plug-in portion 101 to fix the terminal 60 inside the plug-in portion 101. As a preferred embodiment, the elastic stopper 6020 is formed by breaking the two side walls of the transition portion 602 into holes and extending and bending toward the inner side wall of the plug-in portion 101.

[0030] like Figure 2 and Figure 3 As shown, as a preferred embodiment, a cable seal 40 may be provided, which is provided at the rear end of the coaxial cable 50 and inside the plastic housing 20; a rear cover 30 may be further provided, which covers the rear end surface of the cable seal 40 and is provided with a plurality of through holes 301 for the coaxial cable 50 to pass through, so as to fix the coaxial cable 50 and the cable seal 40 in the plastic housing 20. The double sealing structure can enhance the sealing performance and waterproof performance of the overall wiring harness connector.

[0031] Further references Figure 2At least one pair of snap-fit ​​grooves 102 are provided on the outer wall of the plastic inner shell 10, and a protrusion (not shown in the figure) snap-fitted therewith is provided on the inner wall of the plastic outer shell 20, so as to fix the plastic outer shell 20 with the plastic inner shell 10; at least one pair of stopper portions 202 are provided on the outer wall of the plastic outer shell 20, and at least one pair of elastic arms 302 extending toward the plastic outer shell 20 are provided on the back cover 30, and an opening structure is provided on the elastic arms 302 for snap-fitting and connecting with the stopper portions 202.

[0032] Further references Figure 3 As a preferred embodiment, a pair of screws 70 can be provided, a pair of cantilever parts 201 can be provided on the plastic shell 20, screw holes can be provided on the cantilever parts 201, and the screws 70 pass through the screw holes to fix the wiring harness connector at a desired position; at least one pair of elastic gaskets 701 and / or gaskets 702 can be added, and the elastic gaskets 701 and / or gaskets 702 are sleeved between the heads of the screws 70 and the screw holes.

[0033] The disassembly and assembly process steps of the detachable wiring harness connector in this embodiment are as follows:

[0034] First, rivet the coaxial cable 50 onto the terminal 60. The terminal 60 with the coaxial cable 50 riveted onto is used as an assembled semi-finished product and is inserted into the plastic inner shell 10. When inserted into the correct position, the elastic stop portion 6020 on the terminal 60 pops up and opens to cooperate with the second limit portion 104 on the plastic inner shell 10 to prevent retreat. At this time, the assembly is considered in place. The terminal 60 with the coaxial cable 50 riveted onto cannot move forward or backward and cannot be withdrawn from the plastic inner shell 10. The process of disassembling it is as follows: Insert the disassembly tool 80 into the release space 105 (such as the insertion space 105) in the insertion portion 101. Figure 4 As shown), until it cannot move, the elastic locking portion 6020 of the terminal 60 is compressed and tightened, and the terminal 60 and the coaxial cable 50 can be pulled out by pulling the coaxial cable 50 exposed outside the plastic shell 20, thereby achieving the purpose of repairing or replacing the coaxial cable 50, the terminal 60 and the plastic inner shell 10 as needed.

[0035] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] The above-mentioned embodiments only express the implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
