Description

Technical Field

[0001] The utility model belongs to the technical field of cable joints, in particular to a waterproof cable joint. Background Art

[0002] A cable is an electrical energy or signal transmission device, usually composed of several or several groups of wires, which are covered with insulation layers, protective layers, shielding layers, etc. During the installation of cables, cable connectors are usually required to connect two groups of cables. Cable connectors are also called cable heads. After the cables are laid, in order to make them a continuous line, each section of the cable must be connected as a whole. Cable connectors are used to lock and fix the incoming and outgoing lines, and play a role in waterproofing, dustproofing and vibration prevention.

[0003] The utility model patent with patent application publication number 202020199921.6 discloses a waterproof cable connector. The disclosed waterproof cable connector includes a connector body, and the connector body includes a cylindrical body. A first threaded portion is provided at one end of the cylindrical body, and a second threaded portion is provided at the other end of the cylindrical body. A protruding step is provided in the middle of the cylindrical body, and the protruding step is arranged around the cylindrical body, and a limiting groove surrounding the cylindrical body is provided on the end surface of the protruding step closer to the first threaded portion; a sealing ring, the sealing ring is sleeved on the cylindrical body, and the sealing ring is partially located in the limiting groove, which can solve the problem of poor sealing performance of the waterproof cable connector.

[0004] However, the above device still has shortcomings in actual use. The most obvious one is that during the use of the cable joint, in order to improve the waterproof ability of the cable joint, the cable joint has high fit and sealing, resulting in poor heat dissipation effect, thereby affecting the use effect of the cable joint. For this reason, we propose a waterproof cable joint. Utility Model Content

[0005] The purpose of the utility model is to provide a waterproof cable connector to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned invention object, the utility model provides the following technical solutions:

[0007] The present application is specifically as follows: a waterproof cable connector, comprising: a connector body and a locking sleeve, the locking sleeve being threadedly connected to the connector body, the inner cavity of the connector body being provided with a heat-conducting sleeve, the outer side wall of the heat-conducting sleeve being evenly fixed with heat-conducting blocks, the heat-conducting blocks being fixedly connected to the inner side wall of the connector body, one end of the connector body being provided with a heat dissipation groove, the side wall of the locking sleeve being fixedly connected with a heat-conducting sheet, and one side wall of the heat-conducting sheet being provided with a connecting groove matching the heat-conducting sleeve.

[0008] As a preferred technical solution of the present application, the heat-conducting sleeve and the heat-conducting block are both made of copper alloy.

[0009] As a preferred technical solution of the present application, the heat conducting plate is made of aluminum nitride, and a necking portion is fixedly connected to the side wall of the heat conducting plate.

[0010] As a preferred technical solution of the present application, one end of the heat-conducting sleeve is located in the inner cavity of the connecting groove and is in contact with the heat-conducting sheet.

[0011] As a preferred technical solution of the present application, a mounting nut is threadedly connected to one side of the outer wall of the joint body, and a waterproof pad is provided on the side wall of the joint body close to the heat dissipation groove.

[0012] As a preferred technical solution of the present application, the inner cavity of the necked portion is provided with a sealing ring for waterproofing.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] In the scheme of this application:

[0015] 1. A heat-conducting sleeve and a heat-conducting block are provided, and a heat-dissipating groove is opened on the joint body. Since the heat-conducting sleeve and the heat-conducting block are made of copper alloy, the heat is transferred to the heat-conducting block through the heat-conducting sleeve, and the heat is dissipated through the heat-dissipating groove by contacting the joint body. At the same time, the heat-conducting sleeve is in contact with the connecting groove on the heat-conducting sheet. The heat-conducting sheet is made of aluminum nitride, and the heat-conducting sheet is arranged on the locking sleeve and directly contacts the outside world, so that the heat of the heat-conducting sleeve can be effectively transferred, thereby improving the heat dissipation effect of the cable joint and ensuring the use effect of the cable joint.

[0016] 2. By arranging a waterproof pad on the outside of the heat dissipation groove and arranging a sealing ring in the locking sleeve, the waterproof ability of the cable connector can be improved through the arrangement of the waterproof pad and the sealing ring, which is convenient for use.
