switch structure

Abstract

A switch structure comprises a button device (3), a moving contact supporting member (4), a contact conductive assembly (5), spring pieces (6), a wire unwinding terminal (7), and a base (8). The contact conductive assembly (5) comprises a conductive member (510) and two fixed contact supporting members. The two fixed contact supporting members extend towards each other to form two fixed contacts that are arranged vertically and correspondingly, the conductive member (510) is formed by connecting two U-shaped structures side by side and is installed on one side of the base (8), the two fixed contact supporting members are respectively of a U-shaped structure and are installed on the other side of the base (8), the spring pieces (6) are installed inside the U-shaped structures of the conductive member (510) and the U-shaped structures of the two fixed contact supporting members, and the spring pieces and the U-shaped structures are combined to form an unthreaded wiring terminal device used for clamping a wire. The switch structure is simple, has a high installation speed and stable working performance, and is safe and reliable.

Description

technical field [0001] The invention relates to the field of wall switches, in particular to a switch structure, in particular to a double-control switch structure without screw terminals. Background technique [0002] At present, the moving contacts in the double control switch structure on the market are mostly in the form of swinging left and right. This structure makes the structure of the device more complicated, the space is difficult to reduce, and it has a certain impact on the assembly efficiency of the device, especially the terminal is threadless. Double control switch for terminal block. In addition, there are many structures of threadless wiring switches currently on the market, and most of them have threadless connection structures that can only connect with a cross-sectional area of ​​2.5mm. 2 Hard wires up to and including 4mm cannot be connected 2 The problem of the hard wire, if the existing threadless wiring switch is hard to connect 4mm 2 Even if it ca...

[0002] At present, the moving contacts in the double control switch structure on the market are mostly in the form of swinging left and right. This structure makes the structure of the device more complicated, the space is difficult to reduce, and it has a certain impact on the assembly efficiency of the device, especially the terminal is threadless. Terminal block double control switch

In addition, there are many structures of threadless wiring switches currently on the market, and most of them have threadless connection structures that can only connect with a cross-sectional area of ​​2.5mm. 2 Hard wires up to and including 4mm cannot be connected 2 The problem of the hard wire, if the existing threadless wiring switch is hard to connect 4mm 2 Even if it can be connected, the electrical contact performance of the terminal and the current-carrying capacity of the hard wire are seriously unbalanced (such as 4mm 2 The safe current-carrying value of the copper core hard wire is 28A, but the safe and stable electrical conductivity of the actual electrical contact of the terminal is less than 28A), and after a maximum of 5 wiring operations, the plastic deformation of the spring inside it Seriously, it will lead to safety hazards such as temperature rise and false connection. In the light case, the current carrying capacity will decrease, and in the severe case, the product will be scrapped due to the failure of electrical contact performance.
