Anti-drop open combined connecting terminal for screw nail

Abstract

The invention discloses an open and combined wiring terminal which can prevent screws from breaking off. The wiring terminal comprises a piece body, screws and a conducting strip. The piece body is provided with a conducting strip seat, the conducting strip seat is provided with the conducting strip and the upper part of the conducting strip is provided with the screws; the screws are connected with a tile-shaped gasket; one side of the piece body is provided with a raised head and the other side is provided with a jack corresponding to the raised head. The wiring terminal is characterized inthat: every two corresponding inverted L-shaped convex ribs are arranged on the connecting surface of the piece body and between the screws and the tile-shaped gasket. A thread off prevention structure is arranged at the position where the screws of the piece body are fixed in the invention so that the screws can not be screwed out or cannot break off outside the given height and the wiring terminal can be plugged in, arranged and fastened without screwing out all screws. Therefore, the wiring terminal can prevent electric accidents caused by slipping out of the screws, further reduces production cost and brings convenience to installation and application.

Description

technical field [0001] The invention relates to a connector for electrical equipment, in particular to a screw anti-loosening open combined terminal. Background technique [0002] At present, most of the terminals used to connect wires on electrical equipment are fixed with screws. Due to the poor shock resistance of the screw fixing, it is easy to loosen, and the screws and gaskets are easy to fall off when connecting, which is prone to accidents. In case of electrical accidents, in order to prevent the screws from falling and loosening, existing terminal blocks that use plug-in connection wires also have guide grooves on the insulators of the terminal blocks and springs on the conductive sheets to prevent the screws from falling. A spring needs to be installed on the sheet, which makes the structure of the conductive sheet particularly complicated, and also increases the manufacturing cost. For the plug-in connection terminal of the wire, it must first fix the connector on...

[0002] At present, most of the terminals used to connect wires on electrical equipment are fixed with screws. Due to the poor shock resistance of the screw fixing, it is easy to loosen, and the screws and gaskets are easy to fall off when connecting, which is prone to accidents. For electrical accidents, in order to prevent the screws from falling and loosening, existing terminal blocks that use plug-in connection wires also have guide grooves on the insulators of the terminal blocks and springs on the conductive sheets to prevent the screws from falling. A spring needs to be installed on the sheet, which makes the structure of the conductive sheet particularly complicated and increases the manufacturing cost. For the plug-in connection terminal of the wire, it must first fix the connector on the terminal of the wire before connecting, which is very inconvenient to install.
