Description

Technical Field

[0001] The utility model belongs to the technical field of contact networks and relates to a connection structure of a segmented insulator and a contact line. Background Art

[0002] In recent years, my country's rail transit has developed rapidly. The normal operation of rail transit such as high-speed rail and light rail is inseparable from the contact network that provides power. The contact network includes segmented insulators and contact wires.

[0003] The traditional connection method of the segmented insulator and the contact wire is as follows: the segmented insulator includes a mounting base, which has a pair of lugs, each of which has a fixing hole. The wire clamp includes a pair of clamping plates, each of which has a through hole. The pair of clamping plates are embedded between the pair of lugs, and the fixing holes and the through holes are matched one by one and bolts are passed through to pre-lock them. Then, the contact wire is inserted and pre-positioned at the bottom of the clamp. Finally, the bolts are tightened to securely connect the lugs and the clamp, securely connect and position the contact wire, and complete the connection between the segmented insulator and the contact wire.

[0004] However, this connection method needs to be connected at the application site, the contact line needs to be pulled for a long time, and multiple debugging is required to complete the connection. The on-site assembly is troublesome and reduces the construction progress. Summary of the Invention

[0005] The purpose of the utility model is to solve the above problems existing in the prior art and propose a connection structure of a segmented insulator and a contact wire. The technical problem solved is how to facilitate the on-site connection of the segmented insulator and the contact wire and speed up the construction progress.

[0006] The purpose of the utility model can be achieved through the following technical solutions: A connection structure of a segmented insulator and a contact wire, comprising a wire clamp, characterized in that it also includes a connector fixedly connected to the segmented insulator, the wire clamp and the contact wire are fixedly connected by fasteners, both sides of one end of the wire clamp have connecting columns, the bottom of the connector has an embedding groove, the groove walls on both sides of the embedding groove have transition holes and elongated clamping holes, the inner end of the transition hole is connected to one end of the clamping hole, the outer end of the transition hole passes through the notch of the embedding groove, the wire clamp is embedded in the embedding groove, the connecting column can be moved to the other end of the clamping hole through the transition hole, so that the wire clamp is clamped with the connector.

[0007] The connector is directly attached to the segmented insulator and pre-assembled. The wire clamp is secured to the contact wire via fasteners, also pre-assembled. During on-site construction, simply pull the wire clamp, moving the connecting post through the transition hole to the other end of the snap-in hole. This engages the wire clamp and connector, completing the connection between the segmented insulator and the contact wire. This facilitates on-site connection and speeds up construction.

[0008] In the aforementioned structure for connecting a segmented insulator to a contact wire, the connector includes a main body having a pair of protruding lugs at the bottom of the inner end of the main body. The insertion groove is formed between the lugs, and the transition hole and the clamping hole are located inside the lugs. This structure, with the insertion groove, transition hole, and clamping hole protruding, facilitates workers in inserting the connecting column into the clamping hole, facilitating on-site connection of the connector and the wire clamp, and accelerating construction progress.

[0009] In the aforementioned structure for connecting a segmented insulator to a contact wire, the outer end of the connector has a protruding portion, which has a positioning hole. A positioning bolt is inserted through the positioning hole and abuts against the wire clamp to position the wire clamp and the connector. This structure, by tightening the wire clamp with the positioning bolt to position the wire clamp and the connector, prevents the wire clamp from falling off and improves the stability of the connection structure.

[0010] In the aforementioned structure for connecting a segmented insulator to a contact wire, the connector has a connection hole for connecting the insulator, the connection hole extending through the inner end surface of the connector. One end of the insulator is inserted into the connection hole and then locked with a bolt or pin, making the connection convenient.

[0011] In the above-mentioned connection structure of a segmented insulator and a contact wire, the wire clamp includes a first clamp and a second clamp, both of which have fixing holes, and the first clamp and the second clamp are fixedly connected by fasteners passed through the fixing holes, and the contact wire is clamped and fixed between the bottoms of the first clamp and the second clamp.

[0012] In the above-mentioned connection structure of a segmented insulator and a contact wire, the joint is made of aluminum material, and the wire clamp is made of copper material.

[0013] Compared with the prior art, the connection structure of the segmented insulator and the contact wire provided by the present invention has the following advantages:

[0014] 1. The connector and segmented insulator of this connection structure are pre-assembled, and the wire clamp and contact wire are also pre-assembled. During on-site construction, it is only necessary to pull the wire clamp to move the connecting column through the transition hole to the other end of the clamping hole to clamp the wire clamp and the connector to complete the connection between the segmented insulator and the contact wire. The on-site connection is convenient and the construction progress is accelerated.

[0015] 2. The joint of this connection structure is provided with lugs, so that the embedding groove, transition hole and clamping hole are protruding, which makes it convenient for workers to embed the connecting column into the clamping hole, making it convenient to connect the joint and the wire clamp on site and speeding up the construction progress.
