Embodiment Construction

[0009] Now in conjunction with accompanying drawing, the present invention will be further described

[0010] A piercing internal expansion connector, including a stranded wire 2 and a connector with a hole 4, the stranded wire is inserted into the hole of the connector, and its structure is: the stranded wire 2 is loosely inserted into the connector formed by the surrounding wall In the hole, there is at least one hole 4 or a threaded hole on the surrounding wall, and the steel nail 3 passing through the hole or the screw passing through the threaded hole is deeply buried in the stranded wire 2 in the connector hole. The connector can be a single-head connector 1 with a carrier 6 at one end and a single-head connector 1 for connecting twisted wires at the other end; or a double-head connector 5 for connecting twisted wires at both ends.

Abstract

A puncture inside-expanding type connector belongs to the connecting technical field of stranded wires. The invention is characterized in that the stranded wire is loosely inserted in a hole of the connector formed by surrounding walls. The surrounding walls are provided with at least one hole or one hole with threads. A steel nail passing through the hole or a screw passing through the hole with threads are deeply berried in the stranded wire in the hole of the connector. The connector can be provided with a carrier at one end, and the other end is used for connecting the single head connector of the stranded wire; or two ends are all used for connecting the double-head connector of the twisted line. To implementing the invention has the positive effects of no joint damage, simple structure and operation. As the screw is screwed in the stranded wire to lead the stranded wire to expand to the surrounding walls to form a body with a sleeve pipe, the invention can provide powerful contacting force and is applied to the connection of a wire rope as well as to the connection between two cable stranded wire conductors or used for the connection on the end of a stranded wire conductor. The invention is a very practical and feasible invention with a board application range.

Description

technical field [0001] The invention belongs to the technical field of connection of stranded wires, specifically a connection technology of metal stranded wires. Background technique [0002] The connection between the stranded wire and the connector is usually to insert the stranded wire into the hole of the connector, and then flatten or flatten the connector, so that the inner surface of the connector is in close contact with the stranded wire, generating strong friction and forming a connected state. This approach causes the connector to be deformed in the slightest and destroyed in the worst case; and the connection strength is not large enough. Contents of the invention [0003] The invention provides a piercing internal expansion connector with simple structure, no damage to joints and strong contact force. [0004] The technical scheme that the present invention takes: [0005] A piercing internal expansion connector, including twisted wires and connectors with ...
