Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of switch, in particular to a switch device conducting loop. BACKGROUND

[0002] Switch is a very common item in modern life, through which the circuit can be opened, the current can be interrupted or flow into other electronic components on the circuit, and the conducting loop in the switch is a closed path composed of branches. There are various conducting loops in switches on the market, among which the commonly used one is a wiring frame fixed by a bolt, which can press the wire tightly on the wiring spring. This method is widely used at present.

[0003] However, the traditional conducting loop has the following problems: 1. When the terminal is installed in the switch, it is often necessary to weld it with the rest of the electronic components in the conducting loop. It is difficult to control the quality of welding during production and processing, and it is impossible to guarantee the effect of the product in use. At the same time, the resistance at the welding point does not match the resistance of the rest of the conducting components, and a high temperature is easily generated after power on, which interferes with the use of the rest of the electronic components. 2. The wiring frame fixed by the bolt is relatively cumbersome to install, and it needs to be fixed by external tools, which is not convenient to use. In addition, the fixed way by the bolt occupies a lot of space in the switch, which increases the volume of the product. In the case of higher and higher requirements for product volume, it is difficult for the installer to install in a small space, which is a challenge to the installation efficiency. SUMMARY

[0004] The purpose of the present application is to solve the problems existing in the prior art and provide a switch device conducting loop.

[0005] In order to achieve the above purpose, the present application adopts the following technical scheme:

[0006] A switch device conducting loop, comprising a conducting plate and a wiring spring, wherein the upper side of the conducting plate is provided with a wiring frame, the inside of the wiring frame is embedded with a supporting shaft, the outer side of the supporting shaft is nested with a spring, and the outer side of the spring is nested with a wiring spring.

[0007] Preferably, the conducting plate is integrally formed.

[0008] Preferably, the wiring frame is formed by stamping the conducting plate.

[0009] Preferably, the left side bottom of the wiring spring is provided with a flange, and the wiring spring is clamped to the left side bottom of the wiring frame through the flange.

[0010] Preferably, the spring is a tension spring.

[0011] Preferably, a through hole is formed below the left side surface of the wiring spring plate, and the left end of the spring penetrates through the through hole and is fixedly connected with the wiring spring plate.

[0012] Preferably, the right end of the spring is embedded into the through hole arranged at the bottom of the wiring frame.

[0013] As described above, by adopting the technical scheme, the present application has the following beneficial effects:

[0014] 1. In the present application, the conductive plate is integrally formed, and has higher precision, thereby ensuring the effect of the product in use, and the conductive plate is connected without welding, so that the resistance of the conductive plate remains consistent, and the temperature of the whole conductive plate is more controllable in use, avoiding the temperature rise caused by different resistances, and ensuring the normal use of the remaining electronic components in the switch.

[0015] 2. In the present application, the spring is a tension spring, and when the wire is inserted into the wiring frame, the wire is fixed by the elastic deformation of the wiring spring plate, so that the wire is not fixed by bolts, and when the wiring spring plate is pressed by the wire and moves to the left side of the inner wall of the wiring frame, the spring is elongated, so that the wiring spring plate is pulled to the right by the elastic force of the spring to tightly contact the wire, so as to better fix the wire.
