Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a waterproof connector. Background Art

[0002] A cable waterproof connector is a device used to protect electrical connecting wires or cable connections from water and moisture. This type of connector usually has a waterproof sealing design that can effectively prevent moisture from penetrating into the connection parts, thereby protecting wires and cables from damage. Cable waterproof connectors are usually widely used in outdoor electrical equipment, ships, automobiles, and industrial equipment to ensure the stability and safety of electrical connections. Common types of cable waterproof connectors include circular connectors, right-angle connectors, T-type connectors, etc. They can be selected according to the needs. Suitable specifications and models, when selecting a cable waterproof connector, need to consider factors such as waterproof grade, durability, ease of installation, and required electrical characteristics.

[0003] However, in the prior art, the waterproof connector needs to determine the diameter of the cable during installation. If the cable diameter is larger than the use range of the connector, the cable cannot be installed. If the cable diameter is smaller than the use range of the connector, a gap will exist between the cable and the connector. The connector cannot be used on cables of different specifications, which is a limitation. Utility Model Content

[0004] The purpose of the utility model is to solve the technical problem that in the prior art, when installing a waterproof connector, it is necessary to determine the diameter of the cable. If the diameter of the cable is larger than the use range of the connector, the cable cannot be installed. If the diameter of the cable is smaller than the use range of the connector, a gap exists between the cable and the connector, and the connector cannot be used on cables of different specifications. Therefore, a waterproof connector is proposed.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a waterproof connector, including a connector body, one end of the connector body is connected to a pressing head through a thread, the inner wall surface of the connector body near one end is provided with a positioning groove, the inner wall surface of the positioning groove is embedded with a wire plug, and the lower surface of the connector body is provided with two connecting card grooves, and the interiors of the two connecting card grooves are both engaged and connected with connecting card blocks.

[0006] Furthermore, the lower surfaces of the two connecting blocks are fixedly connected with fasteners, and the interiors of the fasteners are fixedly connected with limiting blocks.

[0007] Furthermore, a guide groove is provided on the inner wall surface of the positioning groove, and the guide groove is funnel-shaped.

[0008] Furthermore, a bidirectional bearing is fixedly connected to the inner wall surface of the pressing head, and an extrusion ring is fixedly connected to the lower surface of the bidirectional bearing.

[0009] Furthermore, the outer surface of the pressing head is provided with a plurality of grooves, and the plurality of grooves are equidistantly distributed.

[0010] Furthermore, two limiting grooves are provided on one side surface of the limiting block, and positioning blocks are embedded in the inner wall surfaces of the two limiting grooves.

[0011] Furthermore, one side surface of the two positioning blocks is fixedly connected to the inner wall surface of the fastener.

[0012] Furthermore, an installation groove is provided on an outer surface of the fastener near one end, and a sealing rubber ring is embedded on the inner wall surface of the installation groove.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] 1. In the utility model, when in use, the pressing head is removed, and then the pressing head and the wire plug are successively put on the outer surface of the cable, and then one end of the cable is connected through the hole opened on the outer surface of the connector body and the limit block, and then the fastener is reset, the fastener is fixed to the connector body, the wire plug is embedded in the interior of the positioning groove, and then the pressing head is tightened to squeeze the wire plug. After the wire plug is stressed, it moves toward the inside of the guide groove, and the inclined inner wall of the guide groove squeezes the wire plug, so that the wire plug is compressed and deformed after being stressed, and fits tightly with the inner wall surface of the guide groove and the outer surface of the cable, thereby ensuring the waterproof effect of the connector. It can be used for cables of different specifications and has a wide range of uses.

[0015] 2. In the utility model, when tightening the pressing head, the extrusion ring fits against one side surface of the wire plug. When the pressing head rotates, the bidirectional bearing rotates to prevent the extrusion ring from rotating under force, prevent the wire plug from twisting, and improve the use experience. Multiple grooves evenly increase the friction when rotating the pressing head to prevent hand slippage. The positioning block engages the limit block through two limit grooves to prevent the limit block from shaking and shifting. The sealing rubber ring inside the installation groove fills the gap between the fastener and the connector body to ensure the sealing effect of the connector body. BRIEF DESCRIPTION OF THE DRAWINGS

The connector can be used for cables of different specifications and has a wide range of uses.
