Description

Technical Field

[0001] The utility model relates to an electrical wiring device, in particular to an electrical casing connector, and belongs to the technical field of electrical wiring equipment. Background Art

[0002] At present, it is necessary to wire the electrical lines of a building during building decoration. The wiring method is to chisel out a wire trough on the wall and then lay the wire tube in the wire trough. When wiring, electricians usually pass the wires through the wire tube first and then lay them into the wire trough. When the length of the wire tube is not enough, it is necessary to use a wire tube connector to connect the wire tube to achieve the required length. Currently, common sleeve connectors are usually 90 degrees and 180 degrees. For wiring at some special angles, there are no suitable connectors to use, which requires a sleeve connector that can adjust the angle. According to the Chinese Utility Model Patent (Application Number: 202020516316.7), an electrical sleeve connector is disclosed. The utility model discloses an electrician sleeve connection elbow, including a hose, both ends of the inner cavity of the hose are fixedly sleeved with a first connection pipe, one end of the outer wall of the first connection pipe is provided with a connection sleeve ring, one side of the inner cavity is provided with a second connection pipe, one end of the outer wall of the second connection pipe is fixedly sleeved with a limit sleeve ring, the limit sleeve ring is slidably engaged with the connection sleeve ring, the hose is provided with a protective outer shell, the hose is composed of a rubber tube and a plurality of reinforcement sleeve rings, and the outer wall of the reinforcement sleeve ring is fixedly sleeved with the rubber tube, and one end of the outer wall of the first connection pipe is provided with an external thread. The utility model utilizes the setting method of the connection sleeve ring, and during installation, the second connection pipe can be used to fix the connection of two pipelines, so that the first connection pipe and the connection sleeve ring are threadedly sleeved again, thereby avoiding the direct use of the hose to connect the pipeline, and the hose can be disassembled by rotating the connection sleeve ring, thereby improving its installation or disassembly efficiency.

By setting the first connector 1, the second connector 2, the bolt 3, the connecting sleeve 4, the connecting piece 5, the sleeve 7, the first rack 8, the second rack 9 and the spring 10, the first connector 1 and the second connector 2 are rotated at the required angle, the connecting sleeve 4 and the connecting piece 5 are rotated around the bolt 3, so that the first rack 8 and the second rack 9 slide relative to each other, and the spring 10 is compressed at the same time. When the appropriate angle is reached, the first connector 1 and the second connector 2 are released, and the spring 10 will give the first connector 1 and the second connector 2 a reversing force, but the first rack 8 and the second rack 9 are both serrated racks, which can prevent the first connector 1 and the second connector 2 from rotating in the opposite direction, thereby realizing the docking of the sleeve 7 suitable for various angles during wiring, and the arrangement is simple and easy to use.

[0027] In this embodiment, if Figure 1 , Figure 2 and Figure 7 As shown, the first rack 8 and the second rack 9 are both sawtooth racks. By setting the first rack 8 and the second rack 9 as sawtooth racks, the first connector 1 and the second connector 2 can be prevented from rotating in the opposite direction.

[0028] In this embodiment, if Figure 1 , Figure 3 and Figure 4 As shown, a thread 11 is provided on the inner side of the connecting pipe 6, and a retaining ring 12 fixedly connected to the inner side of the connecting pipe 6 is provided on one side of the thread 11, and a sealing ring 13 located on the retaining ring 12 is installed between the sleeve 7 and the connecting pipe 6. The sleeve 7 can be sealed by the arrangement of the retaining ring 12 and the sealing ring 13.

The protective plate 14 is an accordion-type protective plate, which is installed between the matching port 402 and the wiring port 502 to play a sealing role. The rotation groove 403 and the slide rail 503 slide in cooperation to facilitate the relative rotation of the first connector 1 and the second connector 2, and at the same time start the sealing effect.

[0031] In this embodiment, if Figure 1-Figure 7 As shown, the working process of an electrical conduit connector provided in this embodiment is as follows:

[0032] Step 1: Rotate the first connector 1 and the second connector 2 at the required angle, and rotate the connecting sleeve 4 and the connecting piece 5 around the bolt 3, so that the first rack 8 and the second rack 9 slide relative to each other, and compress the spring 10 at the same time. When the appropriate angle is reached, release the first connector 1 and the second connector 2. The spring 10 will give the first connector 1 and the second connector 2 a reversing force, but the first rack 8 and the second rack 9 are both serrated racks, which can prevent the first connector 1 and the second connector 2 from rotating in the opposite direction, thereby realizing the docking of the sleeves 7 suitable for various angles during wiring.

[0033] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto.
