Description

Technical Field

[0001] This utility model relates to the field of switches, and in particular to a switch assembly. Background Technology

[0002] A switch is an important component used to control the opening or closing of a circuit. A switch typically includes a housing, on which a button, a first electrical connector, and a second electrical connector are mounted. The button on the housing actuates the second electrical connector, causing it to form or disengage from the first electrical connector, thereby switching the circuit on or off. Existing technology mainly uses a snap-action spring to cooperate with the first electrical connector. The snap-action spring deforms under pressure to a certain extent, causing it to snap and contact the first and second electrical connectors to achieve the requirement of rapid connection or disconnection. However, when this type of switch is used in a high-vibration environment, the spring is prone to deformation due to external vibration, affecting the normal operation of the switch and posing a stability problem. Utility Model Content

[0003] In view of the shortcomings of the existing technology, this utility model provides a switching component that can ensure fast switching and strong stability.

[0004] To achieve the above objectives, this utility model provides a switch assembly, including a housing, a button and a first electrical connector disposed on the housing, and a swing member. One end of the swing member is oscillatingly connected to the housing, and the other end of the swing member extends toward one side of the housing. A second electrical connector and an elastic member are disposed on the swing member. The two ends of the elastic member are respectively connected to the other side of the housing and near the other end of the swing member, and the elastic member is disposed on the movement path of the button. The first electrical connector is disposed on one side inside the housing and includes a first segment and a second segment arranged vertically at intervals. The second electrical connector can form contact with the first segment or form contact with the second segment when it swings with the swing member.

[0005] The advantages of the above technical solution are as follows: A swinging member is installed with one end oscillating and connected to the housing. The other end of the swinging member extends towards one side of the housing. A first electrical connector with vertically spaced first and second segments is installed on one side of the housing. The second electrical connector on the swinging member can make contact with the first or second segment when its other end moves up and down with the swinging member, thus switching the circuit on / off. Furthermore, two ends of an elastic element are connected to the other side of the housing and near the other end of the swinging member, respectively. When the button is pressed, pressure is applied to the center of the elastic element, causing it to form a continuous acceleration through changes in the degree of deformation. Combined with the swinging structure of the swinging member, the second electrical connector accelerates until it quickly passes through the gap between the first and second segments, achieving rapid switching or on / off. Since the switch is driven by the swinging member, a larger distance is required to complete the switching, and external vibrations will not affect normal operation, resulting in greater stability.

[0006] The present invention can be further configured such that: the second electrical connector includes two first contact pieces disposed on both sides of the first electrical connector, the two first contact pieces extend inclined toward each other, and an arc-shaped protrusion is provided near the end.

[0007] With further configuration, the second electrical connector includes two first contact pieces disposed on both sides of the first electrical connector, and the two first contact pieces extend at an angle towards each other, enabling the second electrical connector to form a clamping contact with the first electrical connector, further enhancing stability. Furthermore, an arc-shaped protrusion is provided near the end of the first contact piece, which contacts the first electrical connector through the arc-shaped protrusion, reducing wear and resistance during sliding.

[0008] The present invention can be further configured such that: the swinging member includes a notch, and the first contact piece is disposed in the notch.

[0009] By further designing the oscillating component, a notch is provided for the first contact piece to be positioned therein. The notch can limit the first contact piece and can also guide the oscillating component when it slides by cooperating with the first contact piece.

[0010] The present invention can be further configured as follows: including a vertically extending third electrical connector, the swing member having a through hole near one end for the third electrical connector to pass through, the second electrical connector having a second contact piece with the same structure as the first contact piece at the position corresponding to the through hole, the second contact piece sliding along the guide of the third electrical connector.

[0011] By further configuring a third electrical connector, the third electrical connector is positioned at the through hole at the end where the swinging member has a smaller amplitude of movement when it swings. This allows the second contact piece on the second electrical connector to slide along the guide of the third electrical connector and maintain contact when the swinging member swings.

[0012] The present invention can be further configured such that: an elastic pad is provided at the other end of the swing member, and the swing member forms a buffer part at the upper and lower ends of the elastic pad.

[0013] By further designing the device, an elastic pad is installed at the other end of the swinging component, extending to the outside of the swinging component to form a buffer. During the swinging process, the buffer can abut against the inner wall of the housing to form a buffer, thus preventing abnormal noises or impacts.

[0014] The present invention can be further configured such that: the swing member is provided with an extension block, the housing is provided with a limiting groove for the extension block to extend into, and the extension block can swing with the swing member to abut against the inner wall of the limiting groove.

[0015] By further designing the device, an extension block is provided on the swing component, and a limiting groove is provided in the housing. The movement range of the swing component is limited by the cooperation between the extension block and the limiting groove. Attached Figure Description
