Description

Technical Field

[0001] This utility model relates to the field of cable joint technology, specifically to a metal nut double-locking waterproof cable joint. Background Technology

[0002] Currently available ordinary cable waterproof connectors on the market can only meet one or two of the performance requirements, such as waterproofing, high temperature resistance, shielding, strong locking force, and good sealing performance. They rarely meet multiple performance requirements at the same time.

[0003] Existing ordinary waterproof cable connectors have the following disadvantages: when used in high-temperature environments for extended periods, ordinary waterproof connectors may experience water seepage or leakage, potentially causing short circuits and equipment damage. Furthermore, due to the complex design of the shielding mechanism and its high requirements for the installation environment, the installation dimensions of the shielding mechanism must be considered during installation, resulting in low fault tolerance and increased design costs. Therefore, we propose a double-locking waterproof cable connector with a metal nut. Utility Model Content

[0004] In view of the problems existing in the above-mentioned waterproof cable joints, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a metal nut double-locking waterproof cable connector, which solves the problem of water seepage or leakage that occurs when using ordinary waterproof connectors in long-term high-temperature environments.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A metal nut double-locking waterproof cable connector includes an external screw nut, a connecting cylinder rotatably mounted on one side of the external screw nut, an internal screw nut rotatably mounted inside the connecting cylinder, a plurality of mounting holes fixedly opened on one side of the internal screw nut, two connecting blocks fixedly mounted on the outside of the external screw nut, a first threaded hole fixedly opened on the connecting block, a bolt threaded in the first threaded hole, and two clamping plates threaded on the bolt, the two clamping plates being arranged in opposite directions.

[0008] Preferably, a sealing ring is fixedly provided on one side of the inner screw nut, and a sealing gasket is fixedly provided on the inner side wall of the sealing ring.

[0009] Preferably, the internal screw nut is at the same height as the end face of the connecting cylinder.

[0010] Preferably, the sealing gasket is a rubber gasket.

[0011] Furthermore, two pads are fixedly provided on the top of the clamping plate.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0013] This utility model uses internal and external screw nuts to lock the cable. To prevent ordinary waterproof cable connectors from leaking or seeping under prolonged high temperatures, thus avoiding short circuits and equipment damage, internal and external screw nuts are used to lock the cable. A sealing ring and a sealing gasket are also provided for sealing. Furthermore, to prevent the cable from shifting due to the complex design of the shielding mechanism and its high requirements for the installation environment, and to avoid having to consider the installation dimensions of the shielding mechanism during installation, a clamping plate is used to hold the cable in place, preventing cable movement, providing high fault tolerance, and reducing design costs.
