[0002] As one of the carriers of data exchange, information transmission, and power transmission, connecting wires are widely used in industries such as instrumentation, and their reliability and stability are very important. In some outdoor application scenarios, such as gas meters and monitoring equipment, the connecting wires are connected to the internal intelligent parts. When rainwater enters, it may cause short circuits in the wiring harness and corrosion of the device, thereby affecting the product function. Therefore, higher requirements are placed on waterproof sealing. The waterproof measures for connecting wires are generally achieved by sealing the threading ports or holding the cables tightly through glue filling or waterproof connectors. However, the glue filling process is relatively cumbersome, and it takes time to dry the glue, which affects production efficiency and is also not conducive to maintenance.

[0003] In addition, the use of waterproof connectors is relatively expensive and large in size, which is not suitable for scenes with compact space.

[0004] In view of the above technical problems, improvements need to be made. Utility Model Content

[0031] The wiring harness 1 can be set to two wires, four wires or other numbers of wires according to functional requirements. A flat connector 5 is installed at one end of the wiring harness 1, and connectors of different specifications can be installed at the other end to meet different product requirements; the wire plug 2 is made of rubber material and has a tapered threading hole 201 in the middle. The wire is inserted from the large opening when threading, which is simple and convenient to operate. After insertion, the wiring harness 1 is pre-extruded to form a seal.

[0032] The wire plug 2 includes a body 20 of an L-shaped structure, a connecting block 22 is fixedly provided on the body 20, and guide grooves 21 are formed between the two sides of the connecting block 22 and the body 20; the guide structure 6 includes guide blocks 60 located on both sides of the through hole 31; when the wire plug 2 is assembled with the adapter 3, the guide grooves 21 are assembled on the guide blocks 60;

[0033] During installation, the wire plug 2 is inserted into the guide block 60 of the adapter 3 along the guide groove 21, which is convenient and reliable. At the same time, the rubber on both sides of the guide groove 21 is squeezed and deformed by the guide block 60, ensuring the waterproof performance of both sides, and the wire harness 1 is further squeezed and sealed.

[0034] An assembly groove 23 is formed between the top of the connecting block 22 and the main body 20; symmetrically arranged limit plates 33 are provided in the accommodating cavity 30 near the through hole 31, and connecting plates 34 are installed on the two limit plates 33.
