T-type connecting terminal

Abstract

The invention relates to the circuit connection field, in particular to a connecting terminal. A T-type connecting terminal comprises a case, a base and a wire compressing mechanism, wherein the wire compressing mechanism is fixed in the base, the case covers the base, the base is provided with a branch wire outlet, the wire compressing mechanism comprises an embedding frame, a compressing screw,a nut, a branch wire clip and a trunk wire clip, the embedding frame is fixed in the base and is of a U-shaped structure, the branch wire clip, the trunk wire clip and the nut are sequentially arranged in the embedding frame from the bottom to the opening of the U-shaped structure and slide in the embedding frame along the radial direction, the slide position of the nut is limited by a limiting structure, the nut is provided with a threaded through hole in the radial direction, the compressing screw compresses the trunk wire clip through the threaded through hole, and the trunk wire clip compresses the branch wire clip. The T-type connecting terminal greatly improves the performance and the safety for circuit connection, has obvious sealing effect, and can reliably work in the outdoor high-dust or underwater environment, thereby having wide values of popularization and application.

Description

technical field [0001] The invention relates to the field of circuit connection, in particular to a connection terminal. Background technique [0002] Terminal block is an accessory product used to realize electrical connection, which facilitates the connection of wires. The power industry has special terminal blocks and terminal boxes, all of which are terminal blocks, single-layer, double-layer, current, voltage, common, breakable, etc. With the increasing degree of industrial automation and stricter and more precise industrial control requirements, the amount of terminal blocks is gradually increasing, so the performance and quality of terminal blocks is particularly important. Most of the connecting terminals in the prior art have one end for incoming wires, one end for outgoing wires, and the two ends are tightly connected. This type of terminal works well in a network where one main line is divided into multiple sub-lines, and it is very convenient to use. However, w...

Problems solved by technology

This type of terminal works well in a network where one main line is divided into multiple sub-lines, and it is very convenient to use. However, when it is used in a trunk line network to separate a T-connection of a branch line, it is necessary to cut off the main line first, and then connect the two ends. , and then separate the branch line. This operation of cutting off the main line destroys the original line and affects the connection performance of the main line. It is also very inconvenient to adjust the connection position; The method of winding the branch wires on the main wire and wrapping them with insulating cloth

The most direct harm of this wiring method is poor reliability and high contact resistance, which can easily lead to electrical accidents; and when the branch wire cross section> 10mm 2 It is difficult to operate by manual winding
