Problems solved by technology
For electrical products with this structure, after long-term use, the outer diameter of the cable under long-term pressure will become smaller at the position corresponding to the rubber ring, so the gap between the cable and the rubber ring will increase. Water vapor can easily infiltrate into electrical products from this gap, causing the waterproof function to fail. Therefore, the waterproof function of the current cable connection will be greatly reduced or even completely lost after a period of use.

Embodiment Construction
[0011] A cable structure at the barge junction of the lock head, such as figure 1 , 2 As shown, it includes a cable 1. After the cable 1 is covered with a rigid hollow thin tube 2 (compared to the cable, the thickness of the tube is relatively thin), the cable 1 is injection molded at the docking end. The covering part 3 is provided to cover a section of cable 1 and the hollow thin tube 2 at the junction. In this way, when applied to electrical products that require IP waterproof grades, such as image 3 As shown, put the rubber ring 4 on the outside of the covering part 3, and then screw the lock nut 5 to the electrical connector 6. At this time, the nut 5 squeezes the rubber ring 4 to elastically deform it and then fits it tightly on the outside of the covering part 3. , to prevent water from entering the electrical product from the gap between the lock nut 5, the rubber ring 4 and the covering part 3; since the covering part 3 and the hollow thin tube 2 are made of rigid ...

A cable line structure at a locking head connection line comprises a cable wire, after the connection end of the cable line is sleeved with a steel hollow thin tube, a cladding portion is subjected toinjection molded at the connection end, so that used for a long time, the outer diameter of the long-term pressed cladding portion at the position corresponding to a rubber gasket is not easily reduced, and the gap between the cladding portion and the rubber gasket cannot be increased to prevent water vapor from being permeated into an electrical product from the gap for a long time. Therefore, the cable line structure at the locking head connection line is more reasonable in structure, and can ensure the water-proof function for a long time.
Description
technical field [0001] The invention relates to a cable. Background technique [0002] We know that for electrical products (such as waterproof lamps, etc.) that require IP waterproof ratings, the connection between the cable and the electrical product will be locked with a screw-tightened lock to prevent water from seeping into the connection. In electrical products. At present, when the joint is to be locked, turn the nut, the nut squeezes the rubber ring to make it elastically deformed, and then tightens it on the outer skin of the cable, so as to prevent water from flowing from the lock, the rubber ring and the outer skin of the cable as much as possible. The gap between them enters into the electrical product. For electrical products with this structure, after long-term use, the outer diameter of the cable under long-term pressure will become smaller at the position corresponding to the rubber ring, so the gap between the cable and the rubber ring will increase.
