Description

Technical Field

[0001] This utility model relates to the field of cable connection technology, specifically a non-welded connection structure. Background Technology

[0002] Cables are commonly used for power transmission, but some cables cannot be welded at their connection points, so non-welding structures are required for connection. Existing non-welding structures can connect cables without welding, facilitating normal power transmission.

[0003] In existing technologies, non-welded connection structures are prone to problems such as poor connection tightness, loosening, and poor contact. Utility Model Content

[0004] The purpose of this invention is to provide a non-welded connection structure to solve the problem that existing non-welded connection structures in the background art are prone to poor connection tightness, resulting in loosening and poor contact.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a non-welded connection structure, including a titanium tube, wherein an extrusion connection component is provided on the inner side of the titanium tube, and the extrusion connection component is used to increase the connection stability by extrusion; and a rotating component is provided on the outer side of the middle part of the titanium tube, and the rotating component is used to adjust the position of the glue injection structure.

[0006] The extrusion connection assembly includes two sets of conductive wedges, and the contact surface of the conductive wedges is provided with an inclined surface. The end of the conductive wedge is provided with a connecting ring, and a cable is installed on the outer side of the lower end of the connecting ring.

[0007] The rotating assembly includes a sealing rotating sleeve, and a splicing hole is provided on the right side of the sealing rotating sleeve. An injection hole is provided on the right side of the titanium tube, and the injection hole corresponds to the splicing hole.

[0008] Preferably, the inner sides of the front and back of the titanium tube are provided with threaded grooves, and the inner side of the threaded grooves is provided with threaded rings.

[0009] Preferably, two sets of limiting slip rings are installed on the outer side of the middle part of the titanium tube, and the limiting slip rings are located on the inner side of the sealing rotating sleeve.

[0010] Preferably, an end is installed on the outer side of the threaded ring, and a through hole is provided in the middle of the end, the through hole being located on the outer side of the cable.

[0011] Preferably, the inner side of the sealing rotating sleeve is provided with two sets of limiting slide grooves, and the limiting slide grooves are located outside the limiting slide ring. The top of the sealing rotating sleeve is embedded with a positioning screw.

[0012] Preferably, the conductive wedge has an installation groove on its outer side and an installation bolt on its inner side.

[0013] Preferably, the connecting ring has a through hole in the middle and is located outside the mounting bolt.

[0014] Preferably, a conductive copper clip is installed on the front side of the lower end of the connecting ring, and the conductive copper clip is located on the outside of the cable end.

[0015] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0016] First, this utility model uses a compression connection component to splice conductive wedges with inclined surfaces, which are placed inside the titanium tube. By pulling, the conductive wedges can be expanded to support the inner side of the titanium tube and fixed by compression. Finally, the end cap is fixed to the titanium tube to achieve the restraint effect. Because the conductive wedges are cut with inclined surfaces, they slide to both sides, and the cross-sectional area will become larger and larger, jamming in the middle of the titanium tube. Finally, epoxy resin is filled into the internal pores to seal them. The compression connection component can maintain the stability of the connection.

[0017] Secondly, this utility model has a rotating component installed. After the extrusion connection component is set, the epoxy resin filling cannot be fully filled and is prone to overflow after filling. By setting a sealing rotating sleeve, it can rotate along the titanium tube. During the rotation, the splicing hole and the glue injection hole are kept aligned. After alignment, the glue injection head can be inserted into the inside for glue injection. After the glue injection is completed, it is rotated and the positioning screw head is rotated and inserted to seal, thus avoiding leakage problems. Attached Figure Description

Finally, epoxy resin is filled into the internal pores to seal them. The stability of the connection can be maintained by using the compression connection component.

[0029] With the above technical solution, the titanium tube 1 can be rotated along the sealing rotating sleeve 3.

After splicing, move the spliced ​​wedges to the middle of the titanium tube 1 and pull the two sets of cables 5 at the same time. During the pulling process, the conductive wedges 4 will be squeezed and supported on the inner wall of the titanium tube 1. Then, use a clamp to clamp and fix the end 2 and the threaded groove 101. Grasp the sealing rotating sleeve 3 to align the splicing hole 302 with the glue injection hole 103.
