Abstract

The utility model provides a breaking testing terminal connected by screws. The breaking testing terminal comprises an integrally-formed plastic housing, current strip, at least two or more wire clamping frames, a breaking sliding block, and testing tubes. The pieces of current strip are distributed at the left and the right sides in the housing. The at least two or more wire clamping frames are capable of fixing wires. The breaking sliding block can be connected with the current strip in a bridging manner. The testing tubes achieve common-potential parallel connection between terminals and are used for testing externally-connected terminals. The pedestal of the plastic housing also comprises an installing groove of an installing guide rail. The breaking sliding block which may slides left and right is embedded into to a groove on the current strip. The position of the breaking sliding block is adjusted through a wiring tool operating port in order to achieve the current connection and disconnection of the two separated pieces of current strip. In addition, internal thread is disposed in the testing tube in advance. Common-potential bridging function of multiple terminals can be achieved. The breaking testing terminal completely covers an original product functionally and achieves simple and fast assembly of entire terminals. However, processing difficulty is substantially reduced in the meantime. Compared with a wiring manner of an elevating cylinder, the breaking testing terminal has a simpler and more reliable wiring manner.
