Description

Technical Field

[0001] This utility model relates to the field of wire harness terminal technology, and more specifically, to an assembled wire harness connection terminal head. Background Technology

[0002] A wire harness connector is an interface component that connects to the end of a wire harness to enable a quick and reliable electrical connection between the wire harness and equipment, circuits, or other wire harnesses.

[0003] In existing technologies, the assembly range of wire harness connection terminals is limited. Since electrical terminals and insulating shells are usually integrated and pre-installed, and the assembly process relies on specialized crimping equipment, users cannot freely change the specifications of conductive terminals or adjust the type of wire harness fixing mechanism according to actual needs. On the one hand, application scenarios are limited, and multiple integrated terminal heads must be stocked, which increases costs. On the other hand, maintenance efficiency is low, and on-site operation relies on external equipment, making it difficult to meet the needs of emergency repairs or flexible upgrades. This rigid assembly mode limits the adaptability and maintainability of terminal heads, increases usage costs and complexity, and results in poor performance. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: an assembled wire harness connection terminal head, comprising an insulating shell, conductive terminals, a pressing and fixing mechanism, and a sealing ring. The insulating shell has a socket hole and an adapter mounting cavity at both ends. The conductive terminal is movably sleeved inside the adapter mounting cavity. The conductive terminal includes a conductive terminal base and a conductive plug. The conductive plug is fixedly connected to the conductive terminal base. A damping pad is sleeved inside the adapter mounting cavity, and the damping pad is movably sleeved with the conductive plug. The top of the insulating shell has a top groove and a top opening. The pressing and fixing mechanism is sleeved through the top groove and top opening and extends into the interior of the insulating shell.

This utility model adopts an assembly-type structural design, which combines components such as insulating shell, conductive terminals, pressing and fixing mechanism and sealing ring with movable sleeve and matching cavity, so that users can flexibly replace or adjust related components according to different wire harness specifications and usage scenarios. This improves the adaptability and modularity of the terminal head, reduces the reliance on inventory of various specifications of integral terminal heads, lowers the overall usage cost, and also improves the flexibility and efficiency of on-site assembly and maintenance.

[0012] 2. This utility model incorporates a negative pressure suction mechanism and a suction-connecting air passage inside the insulating shell.

The pressing copper sheet 73 is inserted into the interior of the insulating shell 1 through the top opening 11.

[0018] The pressing and fixing mechanism 7 can be easily fitted into the interior of the insulating shell 1 by fitting with the top groove 10 and the top opening 11. The inner end of the wire harness is pressed and fixed by the pressing copper sheet 73 and the adapter cavity 12. After pressing and fixing, the fitted conductive terminal seat 4 and damping pad 6 are pressed and fixed in the insulating shell 1.

[0019] The bottom of the adapter cavity 12 is an arc surface, the pressed copper sheet 73 is adapted to the bottom of the adapter cavity 12, the adapter cavity 12 penetrates the top of the conductive terminal block 4, and the conductive plug 5 corresponds to the adapter cavity 12 one by one.

[0020] By utilizing the pressing copper sheet 73 and the adapter cavity 12, the inner end of the wire harness is reinforced and fixed.

[0021] The top groove 10 is equipped with a clamping mechanism, which includes a fixed plate 8 and a locking screw 9. The locking screw 9 is threaded into the fixed plate 8.

[0022] The clamping mechanism is used to fix the pressing and fixing mechanism 7 to maintain stability after pressing.

Then, the sealing ring 14 is fitted onto the outside of the wire harness, so that the bare wire end of the wire harness is fitted along the socket hole 3. Insert the wire harness into the adapter cavity 12. Press down the pressing and fixing mechanism 7 to move the pressing copper sheet 73 downward and press the wire harness head, so that the inner end of the wire harness is pressed into the adapter cavity 12 and the conductive terminal seat 4 is pressed and fixed in the adapter mounting cavity 2. Then rotate the adjusting rod 18 so that the adjusting rod 18 drives the movable plug 19 to move down along the bottom cavity 15 and sucks the air inside the connecting groove 16, so that the air pressure in the closed cavity inside the insulating shell 1 decreases, so that the sealing ring 14 and the damping pad 6 are adsorbed and fixed in the insulating shell, completing the assembly.
