Embodiment 1

[0045] Such as figure 1 and figure 2 As shown, the switchgear 10 of an embodiment includes a power lead 100 , a power transmission 200 and a conductive connection 300 . The first end of the lead member 100 is used for electrical connection with a power terminal, and the second end 110 of the lead member 100 is provided with a first contact portion 120 . The power transmission element 200 is provided with a second contact portion 210 , and the second contact portion 210 is used for contacting and electrically connecting with the first contact portion 120 . One end of the conductive connector 300 is connected to the electric lead 100 , and the other end is connected to the power transmission member 200 , and the power lead 100 is electrically connected to the power transmission 200 through the conductive connector 300 . In this embodiment, the electric lead element 100 , the electric transmission element 200 , the first contact portion 120 and the second contact portion 210 a...

Embodiment 2

[0048]On the basis of Embodiment 1, in order to ensure that the conductive connector 300 is still connected to the lead member 100 and the power transmission member 200 when the first contact portion 120 and the second contact portion 210 are out of contact, in one embodiment, as image 3 As shown, the conductive connector 300 is a flexible conductive member 300a with a variable distance between its two ends, that is, the length of the flexible conductive member 300a can be extended or shortened. When the first contact part 120 and the second contact part 210 are separated When in contact, that is, the distance between the lead member 100 and the power transmission member 200 increases, so the flexible conductive member 300a can be stretched to keep the flexible conductive member 300a still connected to the lead member 100 and the power transfer member 200; when the vibration is eliminated, When the first contact part 120 and the second contact part 210 are brought into contact...

Embodiment 3

[0053] On the basis of Embodiment 1, in order to ensure that the conductive connector 300 is still connected to the lead member 100 and the power transmission member 200 when the first contact portion 120 and the second contact portion 210 are out of contact, in one embodiment, as Figure 5 with Figure 6 As shown, the conductive connector 300 includes a connecting body 310 and a plurality of clamping bodies 320, the connecting body 310 is connected to the lead member 100, so as to be electrically connected to the lead member 100, each of the clamping bodies One ends of 320 are respectively connected to the connecting bodies 310 , and the plurality of clamping bodies 320 enclose a clamping space 330 for clamping the power transmission element 200 . In this embodiment, through the abutment between each clamping body 320 and the power transmission part 200, the power transmission part 200 is electrically connected to the clamping body 320 and the connecting body 310, and then el...

Abstract

The invention provides a switching device. The switching device comprises a power leading part, a power transmission part and a conductive connecting part, the first end of the electricity leading piece is electrically connected with a power supply terminal, and the second end of the electricity leading piece is provided with a first contact part; the power transmission piece is provided with a second contact part which is used for being electrically connected with the first contact part in a contact manner; one end of the conductive connecting piece is connected with the electricity leading piece, and the other end is connected with the electricity transmission piece; and the electricity leading piece is electrically connected with the electricity transmission piece through the conductive connecting piece. According to the switching device, when the switching device is vibrated to cause the contact between the first contact part and the second contact part to be separated, because the conductive connecting piece is still electrically connected with the power leading piece and the power transmission piece at the moment, a path formed by the power supply terminal, the power leading piece, the conductive connecting piece, the power transmission piece and the electric equipment is not disconnected; therefore, current can be ensured to normally flow from the power supply terminal to the electric equipment, electric arcs are prevented from being generated at the disconnected position of the first contact part and the second contact part, electric appliances and circuits are protected, and unsafe factors are eliminated.

Description

technical field [0001] The present application relates to the technical field of electric switches, in particular, to a switch device. Background technique [0002] The electric tool switch is used to electrically connect the power supply terminal to the electric device, so that the current from the power terminal flows to the electric device for power supply; wherein the electric tool switch contacts through two unit parts to realize the closed circuit conduction current; however, the traditional Due to the vibration generated by work or the external environment, it is easy to cause the disconnection of the contact connection, and it is easy to generate an arc, which leads to damage and unsafeness of electrical appliances and circuits. Contents of the invention [0003] The purpose of the embodiments of the present application is to provide a switch device, which is used to solve the problem that the traditional electric tool switch is disconnected due to the influence of...
