Abstract

The utility model relates to a threadless wiring terminal structure, which is applied in wall-mounted switches and sockets with the rated voltage being 250V and the rated current no higher than 16A. The threadless wiring terminal comprises a base and a press plate, a wire removing component, a spring plate and a conductive plate are arranged in the base, wherein the spring plate is of a three-level deformation structure, and a clearance with the width less than the diameter or width of a wire is arranged between the free end of the spring plate and the conductive plate; the wire removing component is provided with a wide removing end corresponding to the free end of the spring plate; and the press plate is arranged on the top end of the base and presses the conductive plate. The wire can be effectively connected through the elastic deformation and elasticity of the spring plate, and can be rapidly removed through the wire removing component. Compared with the prior art, the utility model can be operated more conveniently and rapidly, and the wire can be removed with tools or by hand without tools for electrical installation, thereby effectively eliminating the existing troublesome processes for installation of wall-mounted switches and sockets, and greatly improving the working efficiency.

Description

No screw terminal

Technical field

The utility model relate to a kind of rated voltage 250V～, rated current is not more than switch on wall, the socket of 16A, a kind of specifically no screw terminal structure that is applied in switch on wall, the socket.

Technical background

Switch on wall, the most of binding post of screw pressing plate, binding post class that adopts of socket connect lead in the market.Need the frequent screwdriver knockout screw of using like this in electrician's installation process, operating efficiency is low.For improving installation effectiveness, a kind of no screw terminal structure is just arisen at the historic moment.The switch on wall, the socket that also have or not the screw terminal structure on the market, rely on the strain and the elastic force of spring leaf to connect lead, its spring leaf is one-level or secondary distressed structure, it connects sectional area when being the hard lead in 4 square millimeters of lines footpath plug wire and to unload the required power of line very big, the spring leaf distortion is very big, often cause the spring leaf disabler, its wiring has certain limitation.

Summary of the invention

For overcoming the technical problem that above-mentioned prior art exists, the utility model provides a kind of no screw terminal structure, this no screw terminal structure, rely on the strain and the elastic force of spring leaf to connect lead effectively, its spring leaf has three grades of distressed structures, can connect the hard lead in 4 square millimeters of lines footpath, cross section, and plug wire and to unload the required power of line less, plug wire and to unload line smooth and easy.

The above-mentioned no screw terminal structure that the utility model provides both also had and can unload line with instrument, can be that detachable line unloads the line mode for two kinds with hand only without instrument also.

The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be: no screw terminal, comprise pedestal and pressing plate, be provided with in the described pedestal and unload line spare, spring leaf and conducting strip, described base bottom offers wire jack and unloads line spare installing hole; Described spring leaf has three grades of distressed structures, has the gap less than diameter of wire or width between its free end and the conducting strip; The described line spare that unloads has free end with spring leaf) relative configuration unload line end; Described pressing plate is arranged on the pedestal top and is pressed on the conducting strip.

Above-mentioned no screw terminal structure relies on the strain and the elastic force of spring leaf to connect lead effectively, spring leaf has three grades of distressed structures, because its distortion progression is many, the deflection that can allow is big, can connect the hard lead in 4 square millimeters of line footpaths, cross section, and plug wire and to unload the required power of line less, plug wire and to unload line smooth and easy.

Above-mentioned structure of unloading line spare both had and can unload line with instrument, can be that detachable line unloads the line mode for two kinds with hand only without instrument also.

The advantage that no screw terminal structure of the present utility model has compared with prior art is as follows: above-mentioned no screw terminal structure relies on the strain and the elastic force of spring leaf to connect lead effectively, spring leaf has three grades of distressed structures, can connect the hard lead in 4 square millimeters of line footpaths, cross section, and plug wire and to unload the required power of line less, plug wire and to unload line smooth and easy; Next is that the structure of unloading line spare both had and can unload line with instrument, can be that detachable line unloads the line mode for two kinds with hand only without instrument also.

As further improvement of the utility model, described conducting strip is the shaped as frame of base opening, and its top is connected with the spring leaf stiff end with a side, and another side is relative with the free end of spring leaf.

Embodiment

As shown in Figure 1 and Figure 2, it is the structural representation of no screw terminal of the present utility model, comprise pedestal 5 and pressing plate 1, be provided with in the described pedestal 5 and unload line spare 4, spring leaf 3 and conducting strip 2 that described pedestal 5 bottoms offer wire jack 51 and unload line spare installing hole (not shown); Described spring leaf 3 has three grades of distressed structures, has the gap less than diameter of wire or width between its free end 35 and the conducting strip 2; Described unload line spare 4 have with the relative configuration of free end 35 of spring leaf 3 unload line end 42; Described pressing plate 1 is arranged on pedestal 5 tops and is pressed on the conducting strip 2.Described conducting strip 2 is the shaped as frame of base opening, and its top is connected with spring leaf 3 stiff ends 34 with a side, and another side is relative with the free end 35 of spring leaf 3.

As Fig. 3, Fig. 4, shown in Figure 5, during wiring, only need hard lead is inserted in the wiring hole of pedestal, distortion level 33 distortion of hard lead pressuring spring sheet, the distortion level 33 of spring leaf is the

distortion level

32 and 31 distortion of distortion level of pressuring spring sheet again, hard lead can insert, the hard lead of elastic compression that the distortion level 33 of spring leaf, distortion level 32 and distortion level 31 produce.

As Fig. 3, Fig. 4, shown in Figure 6, when unloading line, only with hand or instrument press unload line spare unload wire casing 41 places, unloading line spare rises, unload the distortion level of unloading line end 42 pressuring spring sheets 33 distortion of line spare, the distortion level 33 of spring leaf is the

distortion level

32 and 31 distortion of distortion level of pressuring spring sheet again, is pressed onto and unloads wire casing 41 when concordant with base bottom surface when unloading line spare, spring leaf breaks away from hard lead 6, goes out hard lead 6 with hand-lifting again and gets final product.

What should be understood that is: the foregoing description is just to explanation of the present utility model, rather than to restriction of the present utility model, any innovation and creation that do not exceed in the utility model connotation scope all fall within the protection range of the present utility model.
