Description

Technical Field

[0001] This utility model relates to the technical field of automotive wiring harness plug retainers, specifically to an automotive wiring harness plug retainer with an anti-loosening structure. Background Technology

[0002] Automotive wiring harnesses are the "nerves" of a car's electrical system, responsible for power distribution and signal transmission, directly affecting vehicle performance and safety. Wiring harness plug retainers are key components that ensure reliable wiring harness connections. As cars become more electrified and intelligent, the number of wiring harnesses per vehicle has increased from dozens in traditional fuel vehicles to hundreds in new energy vehicles, resulting in a surge in plug connection points. Moreover, retainers often need to operate in harsh environments with severe vibrations, fluctuating temperatures (-40℃ to 125℃), and corrosion from dust and oil, making the structural defects of traditional retainers increasingly apparent.

[0003] Most existing fasteners are either "snap-on" or "threaded": snap-on fasteners rely on the elasticity of plastic to engage, and long-term vibration can easily cause the snap-on fasteners to fatigue and break, leading to loosening; threaded fasteners require tools to tighten, which is inefficient and they are also prone to loosening under high-frequency vibration, and some fasteners do not have optimized tensile design, so the connection part is prone to displacement when the harness is under tension.

[0004] Loose wiring harness connectors pose a significant hazard, ranging from minor issues like malfunctioning central control screens and reversing radars to more serious problems such as power control and ABS system failures, potentially leading to traffic accidents. Industry data shows that such issues account for over 20% of automotive electronic malfunctions, with 60% stemming from insufficient anti-loosening performance of the wiring harness connectors. Furthermore, repairs require disassembly of components, resulting in high costs and the risk of damaging other parts. Utility Model Content

[0005] Technical problems to be solved

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an automotive wiring harness plug retainer with an anti-loosening structure, which can effectively solve the problem of easy loosening in the existing technology.

[0007] Technical solution

[0008] This utility model provides an automotive wiring harness plug retainer with an anti-loosening structure, including a housing. Side grooves are provided on both sides of the housing, and fasteners are provided in the side grooves. A docking assembly is fixed at the bottom front end of the housing. The fasteners include two sets of limiting plates, a buckle rod disposed between the limiting plates, and a connecting plate fixed to the limiting plates. The buckle rod is disposed on the outside of the housing. Springs are fixed in the connecting plate and the side grooves. The docking assembly includes a docking plate and a front plate fixed to the front end of the docking plate. Inner protrusions are fixed on both sides of the bottom of the docking plate, and outer protrusions are fixed on both sides of the top of the front plate.

[0009] Furthermore, the side groove is an integrated cavity structure with a square groove at the tail end and an arc-shaped groove at the front end connected. The connecting plate is slidably disposed in the arc-shaped groove, the end of the arc-shaped groove is a circular arc structure, and the other part is a straight groove.

[0010] Furthermore, outer plates are fixed to both the inner and outer sides of the square groove, and the two ends of the buckle are fixed to the middle of the limiting plate.

[0011] Furthermore, the bottom of the outer casing is provided with a front end groove, the front plate is fixed to the bottom of the front end groove, and the two side walls of the front end groove are inclined and the openings face outward.

[0012] Furthermore, the front end groove and the outer protrusion are spaced at the same distance, and the outer side wall of the front end groove is fixedly connected to the inner side wall of the outer protrusion.

[0013] Furthermore, the inner sidewall of the inner protrusion is inclined and the opening faces upward.

[0014] Beneficial effects

[0015] In this invention, a front groove structure is opened at the bottom of the outer shell. It adopts an inclined side wall structure and is fixed at the bottom with the docking plate and the front plate. The front groove is fixedly docked with the outer protrusion. Therefore, in use, the external structure is locked in one of the two sets of front grooves, or the external structure is slidably locked on the outside of the outer protrusion, or slidably locked between the inner protrusions. Thus, the three sets of sliding locking structures can be connected and locked with external structures of different sizes and specifications to achieve the function of preliminary fixed connection. Compared with the existing structure, it can expand the application range and connection effect of this device. Through the preliminary connection steps, alignment is performed first, and then insertion is performed to achieve the function of stable connection.

[0016] In this device, after the initial connection is completed, the user can pull the buckle structure outward through the buckle-limiting plate-connecting plate to move it and stretch the outer spring structure. At this time, the buckle can be fastened to the external structure to achieve the function of elastic fixed connection. The spring is stretched in the square groove, so the buckle structure can be used to fix and limit different insertion lengths and different external structures to achieve the final fixed connection and prevent the shell from becoming loose from the external wiring harness.
