Description

Push switch wiring device

The present invention relates to a switch structure, and more particularly to a push switch wiring device having an integrally formed clamping frame for holding a spring.

A switch connector is a power switch element having a connection circuit or a line for connecting a wiring circuit and being mounted in an operation panel or a power distribution box of an electronic device. The switch connector uses a high-temperature and fire-resistant insulating case, and the conductive components, the wiring circuit or the wire of the screw-locking electronic device are disposed therein, and then the conductive element and the wiring circuit or the wire are energized or broken through the operation switch button. Electricity, which in turn establishes a power to cut or turn on the circuit.

A conventional switch connector uses a rectangular frame/limiter in a closed shape and is fitted with a metal dome to press a wire or a wire, and is fastened between the free end and the opposite side plate of the frame by the elastic force of the metal dome. The purpose of electrically contacting the wire or wire with the opposite side plates of the rectangular frame/limiter is achieved. For example, Taiwan Patent Publication No. M526174 "Switching Wiring Device" patent provides a typical embodiment. The restrictor of the rectangular frame disclosed by the switch wiring device is accommodated in the casing, and the metal elastic piece combined under the limiter occupies more volume of the casing, which is disadvantageous to the trend of the switch wiring device toward miniaturization structure and design.

The above-mentioned limiter is stamped and bent into a rectangular frame by a flat blank, and the structural rigidity is limited (not integrally formed). One end of the metal elastic piece is fastened to one side plate of the limiter, and one end is pivotally connected to the column pile of the casing, so that the size of the limiter and the metal elastic piece is too large, and the structure assembled to the outer casing is complicated, and the overall volume cannot be reduced. In addition, when the wire is inserted into or out of the metal dome of the limiter, the operator must use a tool to move the metal dome toward the limiter for replacement or repair, which is inconvenient and time consuming to use.

In view of this, the creator has made great efforts to solve the above problems by focusing on the above-mentioned prior art, and has devoted himself to the application of the theory, that is, the goal of the creator's improvement.
