Background technique

Press, the commonly used detection switch is mainly composed of a base and a cover corresponding to the above-mentioned base. The base is sequentially provided with an arc-shaped space, an actuating groove and a supporting groove. There is a positioning groove and a buckle part respectively at both ends of the space, and a first contact terminal is arranged in the positioning groove, and a second contact terminal is provided on one side of the buckle part for an arc-shaped shrapnel and a function block. 1. A push handle is arranged in sequence, and a frame-shaped contact portion and a hook-shaped contact portion are respectively provided at both ends of the arc-shaped shrapnel, which are formed by corresponding to the positioning groove and the buckle-off portion.

With the above structure, a stacking force can be applied to the push handle to drive the action block to compress the arc-shaped shrapnel to deform, so that the frame-shaped contact part and the hook-shaped contact part simultaneously conduct contact with the first conductive pin and the second conductive pin. Pins are electrically connected to connect to the power supply.

However, as the above-mentioned conventional structure, its structure implies many defects in manufacture and use:

1. The arc-shaped shrapnel is only positioned by the structure of the frame-shaped contact part. After long-term repeated deformation, it is easy to cause deformation and damage to the frame-shaped contact part and affect the service life.

2. The arc-shaped shrapnel is prone to fall off and displacement due to long-term repeated deformation, which seriously affects the stability and quality of the contact.

In view of the lack of the above-mentioned commonly used detection switch in actual application, the author of this case has accumulated many years of personal experience in related industry development practice, carefully studied, and finally developed a detection switch anti-off structure.

Utility model content

The main purpose of this creation is to provide an anti-off structure of the detection switch, which can provide a stable support for the arc-shaped shrapnel, provide better contact quality and stability, and increase the service life of the product.

In order to achieve the above purpose, this creation includes: a base, which is sequentially provided with an arc-shaped space, an actuating slot and a supporting slot connected in sequence, and a positioning slot and a positioning slot at both ends of the arc-shaped space. A buckle part, and a first contact terminal is arranged in the positioning groove, and a second contact terminal is arranged on one side of the buckle part; a top cover is set on the above-mentioned base, and a side end of the top cover is provided with an operation mouth; an arc-shaped shrapnel, corresponding to the above-mentioned arc-shaped space, a frame-shaped contact part and a hook-shaped contact part are respectively provided at both ends of the arc-shaped shrapnel respectively corresponding to a first contact terminal and a second contact terminal, and in The outer end of the frame-shaped contact part is provided with at least one flange; an action block is arranged in the above-mentioned actuating groove; Lateral movement in the groove drives the above-mentioned action block and compresses the deformation of the above-mentioned arc-shaped shrapnel.

With the above structure, the first conductive pin can be kept in constant contact with the frame-shaped contact part of the arc-shaped elastic piece, and the second conductive pin is usually separated from the second conductive piece; when the push handle is laterally pushed against by force, it will The arc-shaped shrapnel is deformed so that the hook-shaped contact portion of the arc-shaped shrapnel contacts the second conductive sheet to achieve the function of circuit conduction.

From the presentation of the above structural forms, it can be seen that this creation has the following advantages:

1. In this creation, since the flange at the outer end of the frame-shaped contact part can generate point friction against the wall of the positioning groove, it can prevent the arc-shaped shrapnel from falling off and shifting due to long-term repeated deformation, thereby providing better contact quality and stability.

2. In this creation, the structural positioning function of the frame-shaped contact part can only be reinforced by the flange at the outer end of the frame-shaped contact part, so as to prevent deformation and damage of the frame-shaped contact part, thereby prolonging the service life of the product.
