Description

Technical Field

[0001] This utility model belongs to the field of connector technology, specifically relating to a quick-connect, crimp-free 4P male connector for wire harness repair. Background Technology

[0002] With the rapid development of automotive electronics, industrial automation, smart homes and other fields, wire harnesses, as the "nerve network" of signal and power transmission, present three major characteristics in their maintenance scenarios: high frequency, complexity and emergency response. From the high temperature and vibration environment of car engine compartments to the narrow space of industrial equipment control cabinets, and to on-site emergency repairs in home appliance after-sales service, all these scenarios place core demands on connectors: "fast installation, stability, weather resistance and ease of operation". Specifically, wire harness repair requires the disassembly and connection of connectors to be completed in a short time.

[0003] Traditional connectors generally use crimped terminal structures, which require special crimping pliers to crimp and fix the terminals to the wires. If the repair site lacks suitable crimping tools, different specifications of terminals require different crimping molds, which makes it impossible to complete the terminal assembly, causing the repair to stall. Moreover, the crimping quality depends on the operator's experience, and it is easy for the terminal to fall off due to being crimped too loosely, or to break due to being crimped too tightly.

[0017] Example Reference Figure 1-5 This is an embodiment of the present invention, which provides a quick-connect, crimp-free 4P male connector for wire harness repair, comprising: The mounting part 100 includes a housing 101, a baffle 102 fixedly connected to the side wall of the housing 101, an external thread 103 provided at the end of the housing 101, and a support platform 104 provided at the bottom of the housing 101. The lower end of the baffle 102 is fixedly connected to the side wall of the support platform 104, and the end of the external thread 103 extends to the side wall of the baffle 102. The connecting part 200 includes a core 201 sealed and inserted inside the housing 101, a main terminal 202 inserted in the middle of the core 201, and a secondary terminal 203 inserted in the side wall of the core 201. The main terminal 202 and the secondary terminal 203 are used together. The ends of the main terminal 202 and the secondary terminal 203 extend to the inside of the housing 101. The ends of the main terminal 202 and the secondary terminal 203 are provided with a wiring positioning groove 205 for use. The wiring positioning groove 205 is an open structure, which makes it easy to insert the wire into the middle of the wiring positioning groove 205. Then, the end of the wiring positioning groove 205 can be pressed together with pliers, or the wire harness can be directly wrapped around the side wall of the wiring positioning groove 205 to achieve quick fixation. The side wall of the core 201 is provided with digital marks that are used in conjunction with the main terminal 202 and the secondary terminal 203 for easy identification of the wire harness.

[0018] Specifically, the support platform 104 has an arc-shaped edge on its side wall, and a positioning post 105 is threadedly connected to the center of the support platform 104. The end of the positioning post 105 is a ball head structure.

[0019] Furthermore, the end of the outer casing 101 is provided with a beveled structure, and the beveled edge of the end of the outer casing 101 extends to the inner side of the end of the outer casing 101.

[0020] Furthermore, a limiting edge 106 is provided at the end of the housing 101. The limiting edge 106 is symmetrically arranged in the middle of the external thread 103, and the end of the limiting edge 106 extends to the end side wall of the housing 101.

[0021] Preferably, the inner wall of the outer shell 101 is provided with a positioning protrusion 107, and the end of the positioning protrusion 107 is engaged with the side wall of the core 201.

[0022] It should be noted that the wiring positioning grooves 205 at the ends of the main terminal 202 and the auxiliary terminal 203 are arranged in parallel, and the other ends of the main terminal 202 and the auxiliary terminal 203 are provided with bent edges for use.

[0023] Preferably, a limiting groove for cooperation is provided at the middle position between the main terminal 202 and the secondary terminal 203, and a sleeve 204 is encapsulated inside the core 201. One set of sleeves 204 is sleeved on the side wall of the middle limiting groove of the main terminal 202, and another set of sleeves 204 is sleeved on the side wall of the middle limiting groove of the secondary terminal 203.

[0024] The outer shell 101 serves as the outer protective carrier of the connector. The positioning protrusion 107 on its inner wall is a strip structure that matches the groove on the side wall of the core 201. The core 201 is axially fixed through interference fit, preventing the core 201 from shifting within the outer shell 101 and ensuring terminal contact stability. The beveled structure at the end of the outer shell 101 facilitates docking with the female connector and provides guidance for the insertion of the core 201. The stop bar 102 and the support platform 104 cooperate to form a support structure, which can disperse the twisting force and impact force borne by the outer shell 101 to the support platform, improving the stability of the overall structure. The external thread 103 is machined on the outer side of the end of the outer shell 101 to improve the sealing performance when docking with the female connector. The support platform 104 provides an installation reference for the connector. The arc edge of the side wall facilitates the guidance of the male connector. The positioning post 105 with the center thread connection can be adjusted by rotation to adjust the extension length. The ball head structure can reduce the frictional resistance with the mounting surface and facilitate fine adjustment of the connector's installation angle. The limiting edge 106 facilitates docking with the mounting base and limits the male connector. When the female connector is mated, the limiting edge 106 can maintain the stability of the male connector position. The core 201 is sealed and inserted into the housing 101. The sealing structure can prevent dust and moisture from entering the connector. The core 201 has stepped holes that are adapted to the main / sub-terminals. The position of the terminals is fixed by the interference fit between the hole wall and the terminal. The main terminal 202 and the sub-terminal 203 are symmetrically distributed on the side wall of the core 201, forming a 4P transmission channel. The mating limiting groove in the middle is interference-fitted with the sleeve 204. The radial constraint of the sleeve fixes the radial position of the terminal in the core, maintaining a stable connection of the wire harness.

[0025] In use, the pre-installed sleeves 204 are respectively fitted onto the intermediate limiting grooves of the main terminal 202 and the auxiliary terminal 203, and the sleeve position is fixed by the interference fit between the sleeve and the limiting groove; then the main / auxiliary terminals are inserted into the stepped holes of the core 201, and the bent edge at the end of the terminal is elastically engaged with the hole wall to achieve the initial fixation of the terminal in the core. Align the pre-installed terminal core 201 with the opening of the housing 101 and insert it along the inclined edge of the end of the housing 101. During the process, the side wall of the core 201 gradually fits into the positioning protrusion 107 on the inner wall of the housing. When the positioning protrusion is fully inserted into the groove of the core 201, the core 201 is fixed. At the same time, the sealing structure of the core 201 and the housing 101 forms a closed protection. The side wall of the core 201 is provided with a stepped edge, which facilitates the cooperation with the stepped groove inside the housing 101 to maintain installation accuracy. The wiring positioning groove 205 is an open structure, which makes it easy to insert the wire into the middle of the wiring positioning groove 205. Then, the end of the wiring positioning groove 205 can be pressed together with pliers, or the wire harness can be directly wrapped around the side wall of the wiring positioning groove 205 to achieve quick fixation.

[0026] In summary, the crimp-free structure eliminates the need for crimping tools; terminal assembly is completed solely through mechanical fixing of the sleeve and core, enabling rapid connector assembly and meeting the needs of quick wire harness repair. Multiple positioning structures ensure precise mating, reducing mating deviations and preventing transmission failures caused by mating misalignment. Limiting edges prevent accidental operation, simplifying connector installation and mating, and lowering the maintenance threshold.
