A terminal wire harness anti-disengagement locking structure

Abstract

This utility model discloses a terminal wire harness anti-disengagement locking structure, relating to the field of wire harness technology. It includes a protective shell with an anti-wear strip on its exterior. A plug and an end are respectively provided at both ends of the protective shell. An insertion hole is provided on the side of the end away from the protective shell, and a slot is provided above the insertion hole on the end. This utility model precisely inserts the plug of one terminal wire harness into the insertion hole on the end of another terminal wire harness. A connecting plate on the plug is correspondingly inserted into the slot on the end. As the connecting plate continues to slide, a locking plate reaches the fixing groove. Upon losing the pressure from the inner wall of the slot, a spring releases its elasticity, pushing the locking plate into the fixing groove. This effectively locks the plug of one terminal wire harness to the end of the other, preventing loosening or detachment of the end and plug due to external factors or contact, thus avoiding any impact on the working state of the wire harness.

Description

Technical Field

[0001] This utility model relates to the field of wire harness technology, specifically to a terminal wire harness anti-disengagement locking structure. Background Technology

[0002] Automotive wiring harnesses are a combination of wires and connectors that transmit electrical energy from the battery to various electrical devices, such as headlights, audio systems, and air conditioning systems. They also transmit sensor signals to the vehicle's control system for monitoring and adjusting vehicle performance.

[0003] The existing authorized announcement number CN218386588U discloses an automotive wiring harness, including a wiring harness body and a first terminal block and a second terminal block respectively fixedly connected to both ends of the wiring harness body. It also includes a collar assembly slidably sleeved on the wiring harness body and a plug-in assembly and mounting component respectively fixedly installed at the bottom and top of the collar assembly. Limiting components are provided on all four sides of the mounting component. The beneficial effects of this utility model are: it enables the splicing of automotive power wiring harnesses together without the need for wire clamps to hold the harnesses, thus avoiding damage to the outer shell of the automotive power wiring harness caused by wire clamps, which would affect the normal service life of the harness. The splicing operation is simple and convenient for operators.

[0004] While the above technical solution enables the orderly arrangement of automotive power harnesses, the connection between the harness ends relies solely on plug-in connections, which may lack sufficient strength. External factors or contact can easily cause the connections to become unstable, leading to loosening or detachment of the ends, affecting harness operation. Furthermore, during fault detection or replacement, maintenance personnel may need to disassemble the entire harness, increasing maintenance time. Additionally, the small contact area of ​​plug-in connections may impede current transmission, impacting performance and reliability. Therefore, we provide a terminal harness anti-disengagement locking structure. Utility Model Content

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] This utility model provides a technical solution: such as Figures 1-4 As shown, in this embodiment, a terminal harness anti-disengagement locking structure includes a protective shell 11. An anti-wear strip 12 is provided on the outside of the protective shell 11. A plug 13 and an end 14 are respectively provided at both ends of the protective shell 11. The anti-wear strip 12 is fixedly connected to the outside of the protective shell 11. A plug 13 and an end 14 are respectively fixedly connected to both ends of the protective shell 11. An insertion hole 15 is provided on the side of the end 14 away from the protective shell 11. A slot 16 is provided above the insertion hole 15 on the end 14. A fixing groove 17 is provided on the top of the end 14. A plug plate 18 is provided on the top of the plug 13. The plug 13 is inserted into the insertion hole 15. A plug plate 18 is fixedly connected to the top of plug 13. A slot 19 is opened at the top of plug 18 away from plug 13. A spring piece 110 is provided inside the slot 19. Plug 18 is inserted into slot 16. The bottom end of spring piece 110 is fixedly connected to the bottom side of the inner wall of slot 19. A retaining plate 111 is provided on the top of spring piece 110. An anti-slip pad 112 is provided on the top of retaining plate 111. The top of spring piece 110 is fixedly connected to the bottom of retaining plate 111. An anti-slip pad 112 is fixedly connected to the top of retaining plate 111. The outside of retaining plate 111 is engaged in the fixing slot 17. The outside of retaining plate 111 is slidably connected to the inner wall of slot 19.

[0021] In this embodiment, when the terminal harness is needed, to ensure a stable connection between the two terminal harnesses, the plug 13 of one terminal harness can be inserted into the socket 15 of the end 14 of the other terminal harness. The connecting plate 18 on the plug 13 will then be inserted into the corresponding slot 16 of the end 14. As the retaining plate 111 moves within the slot 16, it contracts and accumulates within the slot, compressing the spring 110. As the retaining plate 18 continues to slide, the retaining plate 111 reaches the fixing groove 17, thus releasing the pressure from the inner wall of the slot 16. Afterwards, the spring 110 will release its elasticity, pushing the locking plate 111 to engage in the fixing groove 17. This will limit and lock the plug 13 of one terminal wire harness to the end 14 of the other terminal wire harness, preventing the end 14 and plug 13 from loosening or falling off due to external factors or contact, thus affecting the working state of the wire harness. Moreover, it simplifies the operation for maintenance personnel when disassembling the entire wire harness, improving work efficiency. When it is necessary to disassemble the plug 13 and end 14 of the two wire harnesses, simply press the locking plate 111 and pull the plug 13 out of the end 14 with a little force.

[0022] This utility model provides a terminal wire harness anti-disengagement locking structure, the specific working principle of which is as follows: When using the terminal harness, to ensure the stability of the connection between the two terminal harnesses, the operator can precisely insert the plug 13 of one terminal harness into the socket 15 on the end 14 of the other terminal harness. Then, the insert plate 18 connected to the plug 13 will be inserted into the slot 16 on the end 14. During the insertion of the insert plate 18, the retaining plate 111 will move within the slot 16. At this time, the retaining plate 111 will retract and accumulate inside the slot, simultaneously squeezing the spring 110. As the insert plate 18 continues to slide smoothly, the retaining plate 111 will eventually reach the position of the fixing slot 17. When the retaining plate 111 reaches this position, due to the loss of the squeezing effect of the inner wall of the slot 16, the spring 110 will release its elasticity, thereby pushing the retaining plate 111 to accurately engage. Within the fixing slot 17, this design allows for reliable locking between the plug 13 of one terminal harness and the end 14 of another terminal harness. This effectively prevents the end 14 and plug 13 from becoming loose or falling off due to external interference or accidental contact, thus ensuring the normal operation of the harness. Furthermore, for maintenance personnel, this design simplifies the disassembly process when the entire harness needs to be removed. Maintenance personnel can easily complete the disassembly without complicated procedures, greatly improving work efficiency and facilitating equipment maintenance and repair. When it is necessary to disassemble the plug 13 and end 14 of both harnesses, simply press the locking plate 111 and pull the plug 13 out of the end 14 with a little force.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
