Abstract
An overload protection switch. The problem that a switch on the existing plugboard does not have overload protection is mainly solved. The method is characterized in that: a bimetallic strip (3) and a static contact (4) are arranged in the shell, the bimetallic strip comprises a main strip (30) and a deformation strip (31), and a moving contact (311) arranged opposite to the static contact is arranged on the deformation strip; one end of the main sheet is connected with the inner wall of the shell, and the other end of the main sheet is connected with the operating piece; the deformation sheet is used for deforming when the temperature is too high so that the moving contact leaves the fixed contact. The utility model provides an overload protection switch, when the high temperature, bimetallic strip can make static contact and moving contact divide absolutely, and protection switch prevents to appear danger.
Description
Technical Field
The utility model relates to a switch accessory field, concretely relates to overload protection switch.
Background
The current plugboard is provided with a plurality of sockets and a main switch, and the main switch only simply plays the roles of opening and closing at present, so that the circuit is not protected when the temperature rises too high due to faults, and danger is easy to occur.
SUMMERY OF THE UTILITY MODEL
In order to overcome the not enough of background art, the utility model provides an overload protection switch mainly solves the problem that the switch on the present picture peg does not possess overload protection.
The utility model adopts the technical proposal that:
an overload protection switch comprises a shell, wherein an operating piece in movable fit is arranged on the shell, a bimetallic strip and a static contact are arranged in the shell, the bimetallic strip comprises a main strip and a deformation strip, and a moving contact arranged opposite to the static contact is arranged on the deformation strip;
one end of the main sheet is connected with the inner wall of the shell, and the other end of the main sheet is connected with the operating piece;
the deformation sheet is used for deforming when the temperature is too high so that the moving contact leaves the fixed contact.
The operating member is a button.
The button is internally provided with a connecting plate, the connecting plate is provided with a limiting groove, and one end of the main sheet extends into the limiting groove.
The connecting plate comprises a first baffle and a second baffle, and the limiting groove is formed between the first baffle and the second baffle.
The connecting plate is provided with connecting pins, and the button is provided with connecting holes matched with the connecting pins.
The moving contact is arranged below the middle end of the main piece relatively.
And a limiting boss is further arranged in the shell and is oppositely arranged above and below the main sheet.
The beneficial effects of the utility model are that: the utility model provides an overload protection switch, when the high temperature, bimetallic strip can make static contact and moving contact divide absolutely, and protection switch prevents to appear danger.
Drawings

Fig. 2 is a partial perspective view of an embodiment of the present invention.
Fig. 3 is a schematic perspective view of a connecting member according to an embodiment of the present invention.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings: as shown in the figure, the overload protection switch comprises a shell 1, wherein an operating part 2 which is movably matched with the shell is arranged on the shell, a bimetallic strip 3 and a static contact 4 are arranged in the shell, the bimetallic strip comprises a main strip 30 and a deformation strip 31, and a movable contact 311 which is arranged opposite to the static contact is arranged on the deformation strip; one end of the main sheet is connected with the inner wall of the shell, and the other end of the main sheet is connected with the operating piece; the deformation sheet is used for deforming when the temperature is too high so that the moving contact leaves the fixed contact. Under the conventional state, the operating part (can be the button) activity drives the main leaf swing, makes the moving contact leave or contact with the static contact, and when overheated, the deformation piece drives the moving contact and leaves the static contact, no matter how the operating part moved this moment, the static contact can not contact with the moving contact yet, uses safelyr.
In the present invention, as shown in the figure, the operation member is a button. And the button is adopted, so that the operation is more convenient.
The utility model discloses in, as shown in the figure, the inside connecting plate 5 that is equipped with of button, be equipped with spacing groove 51 on the connecting plate, the one end of master slice stretches into the spacing groove. The operation is more stable.
In the present invention, as shown in the figure, the connecting plate includes a first baffle 52 and a second baffle 53, and the limiting groove is formed between the first baffle and the second baffle. The limiting is more stable.
In the utility model discloses in, as shown in the figure, be equipped with on the connecting plate and connect foot 54, be equipped with on the button with connect the connecting hole 21 of foot looks adaptation. The disassembly and the assembly are convenient.
In the present invention, as shown in the figure, the moving contact is relatively disposed below the middle end of the main piece. And deformation is facilitated.
In the description of the present invention, it is to be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are merely for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.
Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.
The embodiments described with reference to the figures are exemplary intended for the purpose of illustrating the invention and are not to be construed as limiting the invention. The examples should not be construed as limiting the present invention, but any modifications made based on the spirit of the present invention should be within the scope of the present invention.
