Description

TECHNICAL FIELD

[0001] The utility model relates to connecting cable technical field especially relates to a waterproof cable assembly. BACKGROUND

[0002] The waterproof cable assembly is generally composed of a cable and a waterproof structure. The cable is usually made of metal materials with good conductivity such as copper or aluminum, responsible for transmitting current or signals. The conductor is wrapped outside by an insulating layer, which plays an insulating protection role to prevent current leakage and short circuit. Common insulating materials include polyethylene and polyvinyl chloride. A shielding layer may also be provided for cables that need to resist interference. It can reduce the influence of external electromagnetic interference on cable signals. The shielding layer is usually composed of metal braid or metal foil. The waterproof structure includes a sealing element and a waterproof housing. The sealing element is provided at the connection between the cable and the connector, such as a rubber sealing ring or sealing glue, to prevent water from entering. For cable assemblies used in special environments, a waterproof housing may be provided to wrap the entire connector and provide better waterproof protection. Waterproof cable assemblies are widely used in outdoor equipment, underwater equipment, ships, cars and other fields to ensure normal operation in humid and water environments and ensure the reliability and safety of equipment.

[0003] For example, the utility model with application number 201910265349.0 discloses a waterproof cable assembly with simple structure and convenient installation. The junction box is provided with a threading hole, the threading hole is provided with a clamping block, and the plug-in part is directly threaded into the threading hole to quickly realize butt joint, save time and effort. At the same time, the plug-in part and the clamping block are staggered and positioned, which can prevent the cable from twisting and protect the internal wiring of the cable.

[0004] However, the above-mentioned application still has some shortcomings:

[0005] The waterproof cable assembly directly threads the plug-in part into the threading hole to realize quick butt joint, which can limit each other and prevent the cable from twisting. However, the waterproof structure on the outside of the cable is poor. When connecting with the junction box, the plug-in part needs to be inserted into the threading hole. However, the end of the plug-in part is larger than the hole diameter of the threading hole. During the insertion process, the plug-in part needs to be pressed to deform. Frequent disassembly and assembly may cause breakage of the plug-in part. In addition, the plug-in part is not easy to disassemble because it is large. There is a gap between the clamping block and the slot. Only the outer block is used for single-layer protection, and the waterproof effect is poor. Water entering the gap may cause the wire to be damp and even flow into the junction box, causing short circuit.

[0006] Therefore, a waterproof cable assembly is designed to optimize the above-mentioned problems. UTILITY MODEL CONTENTS
