Description

Technical Field

[0001] This utility model relates to the field of joints, and more particularly to a waterproof and tension-enhancing three-way joint. Background Technology

[0002] A three-way connector is a connection device that can connect three components or lines simultaneously. It typically has three connection ports that can be connected to different cables, pipes, equipment, etc. The shape and specifications of the ports depend on the usage scenario and the objects being connected. The materials are mostly metals or engineering plastics, and they must take into account properties such as strength, corrosion resistance, and insulation.

[0003] If existing three-way connectors are exposed to moisture, the insulation performance at the connectors will decrease, increasing the risk of leakage and potentially causing short circuits. This will lead to increased contact resistance, affecting current transmission. Furthermore, the connection will be less stable, making it prone to loosening or even falling off when subjected to external force, which will affect the normal operation of the equipment.

[0004] Therefore, in view of the fact that the existing three-way connectors will have reduced insulation performance and affect current transmission if they are exposed to moisture, and their stability will also be reduced, and the connection will easily loosen or even fall off when subjected to external force, a waterproof and tensile-strength three-way connector can be designed with the addition of a silicone structure to make the connector more waterproof and more tensile. Utility Model Content

[0005] To overcome the problem that existing three-way connectors will have reduced insulation performance at the joints if moisture enters, affecting current transmission and stability, and the connection is prone to loosening or even falling off when subjected to external force.

[0006] The technical solution of this utility model is as follows: a waterproof and stretchable three-connector, including a first connector, a second connector, a third connector, and a cable; a second connector is provided on one side of the first connector, a third connector is provided between the second connector and the first connector, a cable is provided between the third connector and the first and second connectors and above the third connector, an outer shell is provided below the third connector, a cavity is provided inside the outer shell, a connecting tube is provided below the cavity, a silicone sealing sleeve is provided outside the lower end of the connecting tube, a silicone reinforcing gasket is provided outside the silicone sealing sleeve, and a wire clamp is installed at each end of the cable.

[0007] Furthermore, a first threaded groove is provided on the inner wall of the lower end of the first connector, and a round tube is provided below the first connector.

[0008] Furthermore, a second threaded groove is provided on the outer wall of the upper end of the round tube, and the round tube is threadedly connected to the first joint through the second threaded groove along the first threaded groove.

[0009] Furthermore, a ring-shaped end is provided below the second connector, and a tube is installed at the upper end of the ring-shaped end.

[0010] Furthermore, the cannula is inserted into the second connector, causing the annular end to be positioned and connected with the second connector.

[0011] Furthermore, the third connector is positioned and snapped into the outer shell. A third threaded groove is provided on the lower outer wall of the outer shell. A connecting shell is provided below the outer shell. A fourth threaded groove is provided on the upper inner wall of the connecting shell. The connecting shell is threadedly connected to the outer shell through the fourth threaded groove along the third threaded groove. The connecting pipe is threadedly connected to the cavity. A conductor is sleeved on the inner side of the cavity.

[0012] Furthermore, the wire clamp is provided outside the first connector, the second connector, or the third connector.

[0013] The beneficial effects of this utility model are as follows: The silicone sealing sleeve of the third connector, by tightly fitting the outer periphery of the connector, forms a waterproof sealing structure, which can effectively prevent external moisture from entering the internal space of the connector, preventing problems such as internal circuit short circuits and corrosion caused by moisture, and ensuring the stable operation of the connector in a humid environment. Through the waterproof protection of the silicone sealing sleeve and the secure fixation of the cable by the wire clamp, the connecting parts can be prevented from rusting and corroding due to moisture and water ingress, which can extend the service life of the connector and related connecting parts, reduce equipment maintenance and replacement costs. The waterproof sealing structure and the cable fixing structure work together to effectively prevent electrical safety accidents such as short circuits and leakage caused by the conductivity of water, providing reliable safety protection for equipment operation and personnel operation, and meeting the relevant electrical safety standards.

[0014] The clamps at both ends of the cable, with their unique fastening structure, form a stable clamping force on the cable, which can effectively resist tensile force and prevent the cable from shaking or being pulled loose at the joint, significantly improving connection stability and ensuring the continuity and reliability of signal or current transmission.

[0015] Even under high-intensity tensile conditions, the connector, thanks to the combination of silicone sealing sleeve and wire clamp design, can maintain a stable connection, ensuring the system operates normally under harsh conditions, improving the reliability and stability of the entire system, and meeting the usage requirements of various complex working environments.
