All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The core of the invention is to provide a cable repeater assembly which can quickly finish wiring work, effectively improve the repeated utilization rate of parts and reduce the running cost of the device.

Please refer to fig. 1 to 14.

The cable relay assembly provided in this embodiment includes: binding post 1, insulating sheath device that is used for fixed and protection binding post 1, main part device 2 that is used for fixed and protection sheath device, the sheath device includes along the axial can dismantle with the terminal sheath 3 that is used for fixed binding post 1 of concatenation, binding post 1 locates in the sheath device, the sheath device is located in main part device 2, the axial both ends of sheath device and main part device 2 all are equipped with the through-hole that is used for making the cable pass with contact binding post 1, the axial both ends of main part device 2 are equipped with the sealing device who is used for sealed and locking the cable.

It should be noted that, two ends of the connection terminal 1 are respectively used for connecting with wires of different cables, so as to avoid the leakage phenomenon of the cable repeater assembly during the operation process, the sheath device needs to be made of an insulating material, and the insulating material can be selected during the actual operation process.

It should be further noted that the terminal sheath 3 is used for fixing the connection terminal 1, and in order to enable the terminal sheath 3 to better fix the connection terminal 1, the terminal sheath 3 may be configured as a device in which an internal cavity structure is matched with the connection terminal 1 in shape and size, so that the connection terminal 1 can be better fixedly placed.

And, terminal sheath 3 can dismantle and the concatenation operation along the axis direction, is favorable to binding post 1 both ends to carry out the wiring operation respectively like this, waits the wiring operation all to accomplish the back, assembles terminal sheath 3 into wholly can again. By arranging the terminal sheath 3 as a splicing device, the service life and the utilization rate of each part of the cable relay assembly can be improved. If the wiring terminal 1 is damaged, the wiring terminal 1 can be replaced by a new wiring terminal 1 only through disassembly operation, so that the wiring terminal can be continuously matched with other parts for use, and the operation cost and the maintenance cost are reduced to a greater extent.

In addition, the main body device 2 is mainly used as a housing for protecting all components inside the housing. Because the main body device 2 can fix and protect the sheath device, the sheath device should match the shape and size of the inner cavity of the main body device 2 to be better fixed by the main body device 2. Preferably, the main body 2 may be made of metal to avoid deformation.

In the actual operation process, the structure, shape, size, material, position, and the like of the connection terminal 1, the sheathing device, and the body device 2 can be determined according to actual conditions and actual requirements.

When the cable relay assembly provided by the invention is used, firstly, the wiring terminal 1 is placed in a part of the terminal sheath 3, namely, the terminal sheath 3 is in an axial split state at the moment, so that the wiring operation is conveniently carried out on two ends of the wiring terminal 1. Then, the insulation layers of both the cables are removed as required, and then one of the cables is inserted through the through hole at the end of the main body device 2, and the wire portion of the cable is crimped to the end of the terminal 1. And then, the wire part of another cable is crimped with the other end of the wiring terminal 1, and after the crimping and wiring operation is finished, the other part of the terminal sheath 3 is covered, so that the terminal sheath 3 is completely assembled, and the wiring terminal 1 can be better fixed.

In addition, because the sheath device is used for fixing and protecting the wiring terminal 1, and the sheath device is made of an insulating material, the risk that the arc striking phenomenon is easy to occur with the main body device 2 under the conditions of high voltage and high current due to the fact that the splicing position of the terminal sheath 3 can be effectively avoided by the sheath device because of a gap.

And finally, penetrating the assembled sheath device into the main body device 2 along the axial direction, and sealing and locking the cables at the two ends through the sealing devices at the two ends of the main body device 2 so as to complete the assembly process of the cable repeater assembly.

This is because both ends of the connection terminal 1 need to be connected to the stripped cable, that is, the stripped portion of the cable needs to be insulated to expose the wire for connection to the connection terminal 1. The cable may form a boss after the insulation layer is stripped, and in order to enable the terminal sheath 3 to effectively limit the axial movement of the cable, a boss matched with the shape and size of the cable after the insulation layer is stripped may be provided at the end of the terminal sheath 3.

If the cable adopts two layers of insulators, after the insulators of the first layer and the second layer are stripped, the cable can form two bosses, so that two bosses matched with the shape and the size of the structure can be correspondingly arranged at two ends of the terminal sheath 3, and the axial movement of the cable and the electric wire can be effectively limited. Of course, if the cable uses a layer of insulator, and only one boss is formed after the insulator is stripped, a boss matched with the shape and size of the structure can be correspondingly arranged at the two ends of the terminal sheath 3.
