AI Technical Summary
When the cable is subjected to a large tensile force, the terminals inside the existing connector harness assembly are prone to loosening, leading to poor contact or failure, which affects the reliability of power or signal transmission.
A cable locking assembly, including a locking seat and a pressure cap, is added to the connector. The cable is clamped by structures such as rubber pads and hooks to prevent the terminals from coming out of the housing. The reliability of the terminal connection is ensured by elastic contact pieces and limiting protrusions.
This effectively prevents the cable from pulling on the terminals, ensuring that the terminals do not loosen, improving the reliability of power or signal transmission, and enhancing the overall reliability of the connector.

Therefore, the directional and positional terms used are for the purpose of explaining and understanding this utility model, and not for limiting the scope of protection of this utility model.
[0024] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments:
[0025] like Figure 1-4 As shown, a connector harness assembly includes multiple cables 1, a connector 2, multiple terminal lugs 3 connected to one end of the multiple cables 1, and a cable locking assembly 4. The connector 2 includes a housing 21 and multiple terminals 22 respectively disposed within the housing 21. The other ends of the multiple cables 1 are respectively connected to the multiple terminals 22. The cable locking assembly 4 includes a locking seat 41 and a pressure cover 42 disposed on the locking seat 41. The locking seat 41 is detachably connected to the housing 21 and is used to restrict the multiple terminals 22 from coming out of the housing 21. Multiple locking and clamping cavities 400 are formed between the locking seat 41 and the pressure cover 42 to clamp the multiple cables 1.
[0026] like Figure 2 and 3As shown, the pressure cap 42 is provided with multiple upper arc-shaped pressure grooves 421, and each of the multiple upper arc-shaped pressure grooves 421 is provided with an upper rubber pad 43 for pressing against the cable 1. The locking seat 41 is provided with multiple lower arc-shaped pressure grooves 411 that cooperate with the multiple upper arc-shaped pressure grooves 421, and each of the multiple lower arc-shaped pressure grooves 411 is provided with a lower rubber pad 44 for pressing against the cable 1. The upper and lower rubber pads press against the cable, preventing the pressure cap and locking seat from damaging the cable. The upper rubber pads 43 and lower rubber pads 44 are provided with multiple anti-slip protrusions that abut against the cable 1. The anti-slip protrusions increase friction, ensuring that the pressure cap and locking seat can be reliably clamped onto the cable, ensuring the reliability of the connection. The locking seat 41 is symmetrically provided with two hooks 412, and the rubber shell 21 is provided with two locking holes 211 that engage with the two hooks 412. The locking seat is connected to the housing via a hook, facilitating assembly and improving efficiency. Multiple bolts 45 are provided on the pressure cap 42, passing through it and connecting to multiple threaded holes in the locking seat 41. The pressure cap and locking seat are connected by bolts, allowing this cable locking assembly to accommodate cables of different diameters, enhancing its versatility and simplifying assembly.
[0027] like Figure 2 and 4 As shown, each terminal 22 is provided with multiple limiting protrusions 221, and the housing 21 is provided with positioning grooves 212 that engage with the multiple limiting protrusions 221. The multiple limiting protrusions play a role in preventing loosening and can ensure a tighter connection between the terminal and the housing. One end of each terminal 22 has a crimping part 222 that connects to the cable 1. The crimping parts 222 of the multiple terminals 22 have limiting pieces 223 that abut against the locking seat 41, forming a limiting fit between the crimping part and the locking seat. The crimping part of the terminal abuts against the locking seat, which can prevent the terminal from loosening or falling off and ensure the reliability of the connection. The other end of each terminal 22 has a cylindrical insertion part 224. The insertion part 224 has an insertion cavity 225. Multiple elastic contact pieces 226 are distributed in a ring array on the insertion part 224. One end of each elastic contact piece 226 has an arc-shaped contact part 227 extending into the insertion cavity 225. The cylindrical connector design ensures reliable terminal connection. The multiple elastic contact pads on the terminals guarantee reliable contact even under high vibration conditions, further enhancing connection reliability. An insertion guide ramp 228 is provided within the opening of the insertion cavity 225. During connector mating, the guide ramp acts as a guide, reducing insertion force and ensuring smooth mating.
[0028] like Figure 1 and 2As shown, multiple cables 1 are each wrapped with a silicone rubber fiberglass sleeve 11. The silicone rubber fiberglass sleeve provides insulation, fire resistance, and heat insulation for the cables, thereby helping to extend the service life of the connector harness assembly.
[0029] Adding a cable locking component to the connector clamps multiple cables, effectively preventing the cables from pulling the terminals due to tension. The locking seat also prevents the terminals from coming off the housing, avoiding loosening and ensuring the reliability of the terminal connection, thereby improving the reliability of power or signal transmission.
[0030] The above description is only one embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model; the scope of protection of the present utility model is defined by the claims in the claims, and all equivalent changes and modifications made in accordance with the utility model are within the scope of protection of the present utility model patent.
