Description

Technical Field

[0001] This utility model relates to a waterproof wiring harness for automotive GPS. Background Technology

[0002] Automotive GPS waterproof wiring harnesses are crucial connecting components used to link the vehicle's GPS module to the power and signal control systems. Their primary function is to ensure reliable electrical signal transmission in complex automotive environments and to prevent rainwater, dust, or other impurities from entering the wiring harness connections through a protective structure, ensuring long-term stable operation of the GPS system under conditions of high humidity, rain, and vibration. Typically, automotive GPS waterproof wiring harnesses consist of a harness body, a plug, seals, and an outer protective shell. Electrical connections are achieved through the insertion of pins and sockets, and waterproof protection is achieved through a sealing structure. However, existing automotive GPS waterproof wiring harnesses still have the following shortcomings: In existing harness structures, after the harness body and plug body are connected, the joint is often exposed, relying solely on simple rubber rings or sealant for sealing. When the vehicle is driven in rainy weather or subjected to high-pressure washing, moisture can easily seep in through the connection gaps or lead-in ports, leading to pin oxidation, short circuits, or abnormal power supply to the GPS module, resulting in limited protective effectiveness. Traditional wiring harness plugs are mostly single-layer snap-fit ​​or friction-fit structures, lacking robust limiting or locking devices at the connection points. When a vehicle is in a vibrating environment for a long time, the plug and protective components are prone to loosening or shifting, causing unstable signal transmission or even plug detachment, which affects the reliability of the system. Improvements and optimizations are made to address this issue. Utility Model Content

Detailed Implementation

[0012] like Figure 1-6 As shown, the waterproof GPS wiring harness of this utility model includes a wiring harness body 1, a wiring harness plug body 3 for inserting wiring harness pins, a rubber block 2, and a wiring harness protective shell 4. The wiring harness plug body 3 includes a plug socket 13 and a plug mating portion 14 spaced apart at the front end of the plug socket 13. The plug mating portion 14 has a plug inner insertion hole 15 for inserting the wiring harness pins. The wiring harness pins are connected to the end of the wiring harness body 1. The rubber block 2 includes a rubber block body 6 and a rubber block wire wrapping portion 7. The rubber block body 6 has a rubber block inner groove 9 for dividing the wire at the end of the wiring harness body 1. The rubber block wire wrapping portion 7 has a rubber block inner hole 8 for the end of the wiring harness body 1 to pass through and communicate with the bottom of the rubber block inner groove 9. The wire harness protective shell 4 includes a protective shell body 17 and a protective shell wrapping part 18. The protective shell body 17 has a protective shell inner cavity 19 for inserting the rubber block 2. The protective shell wrapping part 18 has a protective shell inner limiting groove 20 that communicates with the bottom of the protective shell inner cavity 19 and is used to limit the rubber block wrapping part 7. The bottom of the protective shell inner limiting groove 20 has a protective shell wiring hole 21. The front end of the protective shell body 17 fits against the rear end of the plug body 13. The rubber block 2 allows the end of the wire harness body 1 to branch and lead out in a sealed space, forming a flexible sealing layer that effectively prevents water vapor from penetrating. The wire harness protective shell 4 can increase the connection strength at the docking point and improve the accuracy of the wire harness plug body 3 and the wire harness female socket when they are inserted, thereby improving the overall assembly stability.

[0013] The protective shell body 17 has a protective shell recessed groove 23 at the front end for wire harness branching and routing. The protective shell recessed groove 23 has a protective shell inner cavity 19 in the middle. The left and right ends of the protective shell recessed groove 23 have recessed groove lead-in ports 24 for orderly routing of wire harness branches, preventing wire harness cross-extrusion and compression, and improving the flatness of the assembly surface.

[0014] The plug body 13 has plug body retaining edges 26 at the upper and lower rear ends. The protective shell body 17 has protective shell mating blocks 27 at the upper and lower ends of the protective shell cavity 19 at the front end. The protective shell mating block 27 has a mating block protrusion 28 on the inner side of the front end. The plug body retaining edge 26 has a retaining edge socket 29 for inserting the protective shell mating block 27. The upper and lower end faces of the plug body 13 have plug body slots 30 on the inner side of the plug body retaining edge 26 for engaging the mating block protrusion 28. This achieves a stable locking at the plug connection, significantly improves the connection strength between the wire harness plug body 3 and the wire harness protective shell 4, prevents loosening, and further prevents the plug from misaligning during insertion or pulling, thus improving the tensile and shock resistance of the overall structure.

[0015] The rubber block body 6 has rubber block positioning protrusions 10 at its upper and lower ends. The rubber block positioning protrusions 10 have rubber block anti-retraction openings 31. The upper and lower walls of the inner cavity 19 of the protective shell have protective shell positioning grooves 33 corresponding to the rubber block positioning protrusions 10. The protective shell positioning grooves 33 have protective shell anti-retraction protrusions 34 corresponding to the rubber block anti-retraction openings 31. This can achieve a stable sealing and positioning structure, prevent the rubber block 2 from shifting under vibration or pulling, and maintain the durability of the waterproof seal.

[0016] The wire harness protective shell 4 is made of plastic.

[0017] Installation process: Place the rubber block 2 inside the inner cavity 19 of the wire harness protective shell 4, then pass the wire harness body 1 through the wire routing hole 21 of the protective shell and the inner hole 8 of the rubber block, and branch it in the inner groove 9 of the rubber block so that each branch connects to the wire harness pin. After connection, insert the pin into the plug insertion hole 15 of the wire harness plug body 3, and then use the docking block protrusion 28 of the protective shell docking block 27 to engage with the plug socket groove 30 to achieve a tight connection between the wire harness body 1 and the wire harness protective shell 4.
