[0026] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] The utility model provides a welded spring-clip type battery CCS collection harness. Through the mutual cooperation of the wire harness spring-clip assembly and the limit locking assembly, the tail of the locking piece utilizes the lever principle to make the card slot on the plug-in terminal and the protrusion of the spring-clip locking piece achieve a self-locking effect, which is convenient for users to maintain without any tools. In addition, the limit locking structure has a split structural design. In this way, when the self-locking piece or the limit head metal fatigue deformation affects the locking, it can be freely replaced to improve the flexibility of use.

[0028] Figure 1-Figure 5 The figure shows the overall structure of a welding spring-type battery CCS collection harness of the utility model. Figure 1-5 The main structure of this embodiment includes: a wire harness retaining spring assembly and a limit locking assembly.

[0029] The wire harness spring assembly is used in conjunction with the limit locking assembly. Specifically, the wire harness spring assembly includes a base plate 11, an arc sleeve 12 fixed on the top surface of the base plate 11, a bending plate 13 connected to the side wall of the base plate 11, a long slot 14 opened on the top surface of the base plate 11, and a pressure head slot 15 connected to the long slot 14;

[0030] During specific use, the limit locking assembly is installed and used based on the base plate 11, and the arc sleeve 12 is used to fit with the plug terminal. When the limit head 22 is pressed downward, the limit head 22 drives the self-locking sheet 21 to move in the long slot 14 and bend, so as to complete the automatic locking later.

[0031] The limit locking assembly is used for automatic locking and convenient disassembly. Specifically, the limit locking assembly includes a self-locking piece 21 arranged in the long slot 14, a limit head 22 connected to the self-locking piece 21, a raised covering slope 23 arranged on the top of the self-locking piece 21, a limit frame 24 fixed to the front end of the self-locking piece 21, a groove opening 25 opened on the side of the limit frame 24, a first threaded opening 26 opened on the limit frame 24, and a second threaded opening 27 opened on the top surface of the base plate 11;

[0032] When in use, the base plate 11 is pushed so that the plug-in terminal and the arc sleeve 12 fit together. At this time, the plug-in terminal is pressed on the convex covering slope 23, and the convex covering slope 23 and the self-locking piece 21 are subjected to pressure. Since the self-locking piece 21 is elastic, the self-locking piece 21 is squeezed and bent downward. At this time, the plug-in terminal is continued to be pushed forward. When the groove on the plug-in terminal moves to the position of the convex covering slope 23, the bent self-locking piece 21 returns to its original position. The self-locking piece 21 drives the convex covering slope 23 and the groove of the plug-in terminal to fit each other for locking and limiting. Such a structural design When disassembly is required, the user manually presses the limit head 22 downward, and the limit head 22 drives the self-locking piece 21 to bend downward, and the raised covering slope 23 is separated from the groove of the plug-in terminal. At this time, the user pushes the base plate 11 backward to complete the removal of the plug-in terminal and the wiring harness. When the frequent bending of the self-locking piece 21 produces metal fatigue and affects normal use, the user unscrews the screw passing through the first threaded opening 26 and the second threaded opening 27 to separate the limit frame 24 from the frame of the base plate 11. In this way, the self-locking piece 21 can be replaced, which is convenient and flexible to use.

[0033] Furthermore, by providing a replacement component, it is convenient to replace the raised covering slope 23 with any shape, which is suitable for self-locking connection of plug-in terminals with slots of different shapes, thereby improving applicability;

[0034] Specifically, it also includes a replacement component, which includes a circular hole 31 opened on the self-locking plate 21, a threaded rod 32 fixed to the bottom surface of the raised covering slope 23, and a nut 33 arranged below the threaded rod 32, and the nut 33 and the threaded rod 32 are connected to each other;

[0035] During actual use, the user unscrews the nut 33, and then pulls the raised covering slope 23 upward with the hand, so that the raised covering slope 23 can be removed and replaced, so that the applicable one can be selected, thereby improving applicability.

[0036] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
