The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0026] Reference Figure 1-4 The present invention provides a prefabricated branch connector for an insulated cable, comprising: a connector housing 1, an arc-shaped groove 101 being provided on one side of the connector housing 1, a connector pipe 2 being fixedly connected to one side of the connector housing 1, the connector pipe 2 passing through the connector housing 1, an adjustment unit 3 being provided on one end thereof, and a sealing unit 4 being provided on the upper end of the connector housing 1;

[0027] Adjustment unit 3 includes an adjustment housing 301 fixedly connected to one end of connecting pipe 1 2. A slide 302 is provided on the inner wall of adjustment housing 301. Connecting pipe 2 303 is fixedly connected to one side of slide 302. Connecting pipe 2 303 and the inner walls of connecting pipe 1 2 are both provided with clamping units 5. Adjustment unit 3 can be used to adjust the connection angle between the main cable and the branch cable.

[0028] The sealing unit 4 includes a cover 401 mounted on the upper end of the connector housing 1. A sealing gasket 402 is fixedly connected to the center of the lower end surface of the cover 401. A plurality of symmetrically arranged bolts 403 are threadedly connected to the upper portion of the cover 401. The sealing unit 4 improves the sealing performance of the connection between the main cable and the branch cable.

[0029] The sealing gasket 402 is adapted to the upper end surface of the regulating housing 301 and is made of an insulating material. The sealing gasket 402 can seal the upper end of the regulating housing 301 to ensure the sealing of the connection.

[0030] The clamping unit 5 includes a clamping screw 501 threadedly connected to the outer walls of the second connecting tube 303 and the first connecting tube 2. A handle 502 is fixedly connected to one end of the clamping screw 501. The end of the handle 502, away from the clamping screw 501, is rotatably connected to a clamping block 503 via a rotating shaft. The upper and lower ends of the clamping block 503 are respectively connected to the inner walls of the second connecting tube 303 and the first connecting tube 2. The clamping unit 5 can clamp the outer walls of the main cable and branch cable, preventing the main cables and branch cables from being separated from the second connecting tube 303 and the first connecting tube 2 due to external pressure.

[0031] The shape of the clamping block 503 is arc-shaped, and a protective pad is fixedly connected to the inner wall of the clamping block 503. The arc-shaped clamping block 503 is adapted to the outer side walls of the main cable and the branch cable.

[0032] The outer wall of the slide plate 302 is adapted to the inner wall of the adjustment housing 301, and the slide plate 302 is slidably connected to the inner wall of the adjustment housing 301. The stability of the slide plate 302 is improved by the sliding connection.

The arc groove 101 can guide the second connecting pipe 303 to adjust its angle.

[0034] Working principle: When in use, the main cable is inserted into the connecting tube 1 2 and the branch cable is inserted into the connecting tube 2 303, so that the main cable and the branch cable are connected in the adjusting shell 301. At this time, the slide plate 302 can be used to slide inside the adjusting shell 301, and the position of the connecting tube 2 303 can be adjusted under the guidance of the arc groove 101, so as to adjust the angle of the cable connection. After the connection is completed, the handle 502 can be rotated to drive the clamping screw 501 and the clamping block 503 to clamp the outer wall of the branch cable and the main cable of the connecting tube 2 303 and the connecting tube 1 2 to prevent the main cable and the branch cable from being separated from the connecting tube 2 303 and the connecting tube 1 2 due to external pressure, thereby preventing damage to the cable. After clamping is completed, the shell cover 401 can be covered on the upper end of the connector shell 1 and fixed with bolts 403. At this time, the sealing gasket 402 is located at the upper end of the adjusting shell 301, thereby protecting the connection between the main cable and the branch cable, improving the sealing of the adjusting shell 301, and ensuring the insulation performance of the cable connection.

[0035] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
