Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cable wiring, in particular to a cable wiring head. BACKGROUND

[0002] The cable is made of one or more mutually insulated conductors and an outer insulating protective layer, and is a wire for transmitting power or information from one place to another. During use, when the cable is externally connected to a small power consumption site, the cable needs to be disconnected, and the external cable needs to be connected to the cable conductor to achieve the transmission of appropriate power.

[0003] When the existing cable is externally connected, the cable outer skin needs to be peeled off, and the cable needs to be wound on the cable conductor to realize the connection. However, due to the high hardness of the cable outer skin, a special tool is needed to cut the outer sheath of the single core inside the integrated cable. Since the work site may be in various positions, on the one hand, workers often have difficulty finding the right angle to peel off the cable, and on the other hand, the hardness of the cable itself makes this work very difficult. Moreover, there may be many cores inside a cable that need to be externally connected, which makes it difficult for workers to peel off the cable skin and connect the external cable to the required cable conductor. Moreover, the cable conductor is formed by twisting, and the tightness is high, making it difficult to tightly connect the external cable to the cable conductor, which easily causes loose connection and affects the stable use of the connection. Therefore, there is an urgent need for a wiring head that can realize the connection of the external cable to the cable. SUMMARY

[0004] The purpose of the present application is to provide a cable wiring head to solve the problems raised in the background.

[0005] To achieve the above purpose, the present application provides the following technical scheme: a cable wiring head, comprising a connector sleeve and a connector body, both ends of the connector sleeve are connected with a wiring end, the central top of the connector sleeve is connected with a second fixed end, both ends of the top of the connector sleeve are connected with a first fixed end, the central bottom of the connector sleeve is provided with a limiting end, the inside of the limiting end is fixed with the connector body, both ends of the connector body are provided with a wiring hole in communication with the wiring end, the top of the connector body is provided with a fixed hole in communication with the first fixed end and the second fixed end, the fixed hole in the inside of the first fixed end is spirally fixed with a second bolt, and the fixed hole in the inside of the second fixed end is spirally fixed with a first bolt.

[0006] Preferably, the top of the first fixed end and the second fixed end is hinged with a waterproof sealing cover, and the inside of the second fixed end is provided with two fixed holes.

[0007] Preferably, the top of the first bolt and the second bolt is provided with a fixed slot, and the fixed slot is a polygonal structure.

[0008] Preferably, the cross section of the joint body is configured as a "J" shape structure, and the joint body is made of a corrosion-resistant conductive alloy.

[0009] Preferably, the limiting end is matched with the joint body and attached to the outside of the joint body, and an opening is arranged between one end of the limiting end and the joint sleeve, and the limiting end at the opening is slightly higher than the joint body and is provided with a limiting protrusion.

[0010] Preferably, the first bolt is provided with a limiting ring above the threaded connection with the fixing hole, and the diameter of the limiting ring is greater than the hole diameter of the fixing hole.

[0011] Preferably, the fixing hole is provided with an annular limiting table below the threaded connection with the first bolt, and the inner diameter of the annular limiting table is smaller than the thread diameter of the first bolt.

[0012] Compared with the prior art, the cable terminal of the present application has the following advantages: the joint sleeve and the joint body are used to enable the cable to be inserted into the hook groove of the joint body through the opening between the limiting end and the joint sleeve, and the cable core is locked by the first bolt, so that the cable conductor is fixed, and the connection between the external wire and the cable is realized by locking the wire to be connected by the second bolt in the terminal, which is simple in structure and convenient to operate. The traditional wiring method requires the cable sheath to be removed before wiring, which improves the convenience of cable wiring. The two terminals are located at the two ends of the joint sleeve, so that cables in different directions can be connected to the device, improving the applicability of the device. The waterproof sealing cover connected to the top of the first and second fixing ends can effectively seal the top of the first and second fixing ends, preventing environmental moisture from entering the wiring position through the first and second fixing ends and causing corrosion of the cable terminal, ensuring normal use of the wiring, and having high practicality.

[0013] Secondly, the cable terminal of the present application has a long strip structure, which occupies less space during use. For example, when multiple external wires need to be branched out, the present application only needs to peel off the outer sheath of the integrated cable for a short distance, and the internal cables can be installed with the cable terminal of the present application at the same position, without sequentially connecting the cables along the length direction. Therefore, the present application is more convenient for construction, causes less damage to the cables, and can be used in narrow environments. BRIEF DESCRIPTION OF DRAWINGS
