Description

Technical Field

[0001] This utility model relates to a flange-type waterproof cable connector. Background Technology

[0002] Waterproof cable connectors are cable connection components whose main function is to provide safe and stable mechanical fixation and electrical connection for cables. They also prevent moisture, dust, and other impurities from seeping into the equipment through a sealing structure, thus ensuring the long-term stable operation of the entire system. Existing waterproof cable connectors typically consist of a connection body, clamping components, and a sealing ring. The cable is fixed by the clamping element inside the connector, while the sealing gasket provides a certain degree of waterproofing. However, in long-term application, traditional waterproof cable connectors still have the following shortcomings: 1. Most existing connector clamping mechanisms rely on a single nut clamping claw or ferrule structure. When the cable diameter is large or the outer sheath is hard, the clamping force is insufficient, failing to form a stable clamp, easily leading to cable slippage or connector loosening; 2. Waterproof cable connectors are not designed with flange positioning structures for equipment housings, making reliable planar locking impossible during installation. This results in gaps or misalignment at the connector-equipment interface, affecting the overall protection level. Improvements and optimizations are needed to address these issues. Utility Model Content

[0003] To solve the above problems, the technical problem to be solved by this utility model is to provide a flange-type waterproof cable connector.

[0004] The technical solution adopted by this utility model of flange-type waterproof cable connector is characterized by comprising a connector body, a connector clamping assembly disposed within the connector body, a tightening cap, and a waterproof clamping pad. The connector clamping assembly comprises an inner sheath and a clamping sleeve. The inner sheath has an inner hole for cable passage. The clamping sleeve comprises a clamping sleeve fitting portion fitted outside the inner sheath and clamping claw blocks arranged in a ring at the front end of the clamping sleeve fitting portion. The connector body comprises a seat body flange mounting portion and a seat body threaded mating portion disposed in the middle of the seat body flange mounting portion. The tightening cap has an internal thread that is threadedly connected to the seat body threaded mating portion and an internal conical surface that facilitates the tightening of the clamping claw blocks. The connector body is divided into an upper positioning groove for positioning the inner sheath and a lower extrusion groove for installing the waterproof clamping pad by a positioning plate within the seat body. The positioning plate within the seat body has a positioning plate clearance hole for cable passage, and the seat body flange mounting portion has a seat body flange mounting hole.

[0005] The waterproof clamping pad includes a clamping pad bottom that is connected to the mounting part of the seat flange and a clamping pad compression part that is located on the clamping pad bottom and placed in the compression groove of the seat. The clamping pad compression part has a clamping pad thread hole that communicates with the inner hole of the inner sheath. The outer wall of the clamping pad compression part has a clamping pad retraction groove that facilitates retraction when pressed down. The height of the clamping pad compression part is greater than the depth of the compression groove of the seat. The bottom of the clamping pad has a clamping pad connection hole that communicates with the mounting hole of the seat flange.

[0006] The inner wall of the lower extrusion groove of the seat body is provided with an inner conical surface that facilitates the tightening of the clamping pad extrusion part.

[0007] The bottom of the clamping pad is provided with clamping pad locking blocks at intervals around the clamping pad compression part. The clamping pad locking blocks have a T-shaped structure.
