Description

Switch shrapnel and micro switch

The invention relates to the technical field of micro switches, and specifically relates to a switch spring piece and a micro switch.

A micro switch is a contact mechanism with a small contact spacing and a snap-action mechanism that performs switching operations with a specified stroke and a specified force. It is covered with a shell and has a driving rod on the outside. Because the contact spacing of the switch is relatively Small, so it is called a micro switch, also known as a sensitive switch. It is mostly used for sensing a single or a small number of objects, such as opening and closing doors, switching electronic products, or using a mouse.

Existing micro switches used for warehousing storage location sensing are usually equipped with trigger shrapnel. When storing objects, the object presses the trigger shrapnel to make the contacts contact, thereby closing the switch. However, with the continuous use of micro switches, the trigger shrapnel is used in many places. During the first movement, its lateral accuracy cannot be guaranteed and misalignment is prone to occur. Moreover, its structural strength is poor and it is prone to deformation.

The purpose of this creation is to provide a switch spring piece and a micro switch to solve the technical problem in the existing micro switch that the switch spring piece has low lateral accuracy during movement; the preferred one among the many technical solutions provided by the present invention There are many technical effects that technical solutions can produce; see below for details.

The present invention provides a switch spring piece, which is used to be arranged on the switch body. The switch spring piece includes a spring piece body, wherein: the spring piece body is provided with a guide cavity, and the guide cavity is adapted to the switch body, so that the spring piece itself The body can move along a fixed trajectory relative to the switch body.

Preferably, both sides of the elastic piece body are bent downward to form bending guide pieces, and the bottom side of the elastic piece body is located in the space between the two bending guide pieces to form the guide cavity.

Preferably, the bending guide piece is arranged vertically relative to the elastic piece body.

Preferably, an anti-jamming portion is provided at an end of the elastic piece body.

Preferably, the anti-jamming portion is configured to prevent jamming, and the end of the spring piece body is bent downward to form the anti-jamming portion.

Preferably, the anti-card is arranged vertically relative to the elastic sheet body.

Preferably, a connection portion is provided at an end of the elastic piece body away from the anti-jamming portion, and the connection portion is used to connect the switch body.

Preferably, the connecting portion is provided with a connecting lug, and the connecting lug is provided with a mounting groove.

The present invention provides a micro switch, which includes a switch body and any one of the above-mentioned switch spring pieces.

The switch shrapnel and micro switch provided by the present invention have at least the following beneficial effects:

The switch elastic piece includes a elastic piece body, and a guide cavity is provided on the elastic piece body. The guide cavity is adapted to the switch body. During the opening and closing process of the switch, the guide cavity has a guiding function so that the elastic piece body can move relative to the switch. The body moves back and forth according to a fixed trajectory, which can effectively ensure the lateral accuracy during the movement of the shrapnel body.

The micro switch includes a switch body and the switch spring piece. The switch body is the circuit structure of the micro switch. The switch spring piece is the triggering structure of the micro switch. The switch spring piece has a guide cavity, which can effectively ensure the opening and closing effect.

This new type of switch can move along a fixed trajectory through the switch spring piece with a guide cavity during the opening and closing process, has good lateral accuracy, and has a remarkable switch opening and closing effect.
