AI Technical Summary
In existing swing switch products, the interference matching of the spring and swing slide causes the switch to be too loud and the performance will be degraded when worn.
By reducing the size of the accommodating cavity of the switch lever, the compression spring only performs axial deformation movement in the accommodating cavity, cancels the interference coordination between the compression spring and the swing plate, and the compression spring and the swing plate move in synchronization during the switching lever to reduce the force of the swing plate to impact the static contact plate of the L-pole assembly.
It effectively reduces the switching sound, improves the performance and wear resistance of the switch, and keeps the swaying plate and the L-pole assembly static contact plate always in contact.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of switches and sockets, in particular to a low-noise swing switch structure. Background Art
[0002] See also Figure 1 , Figure 2 At present, the swing switch products on the market usually use the radial bending deformation of the spring (such as Figure 1 As shown below), keep the contact between the parts; this structure requires the spring and the swing piece to have an interference fit. When the switch is moved, the radial bending of the spring jumps from one side to the other (as shown below Figure 2 As shown in the figure), the swing piece is quickly disconnected, and the contact force with the static contact piece of the L-pole component also increases, thus affecting the switching sound, and the switching sound is too loud. Utility Model Content
[0003] The purpose of the utility model is to provide a low-noise pendulum switch structure. By reducing the size of the inner cavity of the switch shift block that accommodates the compression spring, the compression spring only performs axial deformation movement (compression, release of elastic force, etc.) in the accommodating cavity, and the interference fit structure between the compression spring and the pendulum is eliminated. During the toggling process of the switch shift block, the compression spring and the pendulum move at different frequencies (asynchronous movement), thereby reducing the force of the pendulum hitting the static contact piece of the L-pole component, thereby reducing the switch sound.
[0004] The purpose of the utility model is achieved in this way:
[0005] A low-noise pendulum switch structure includes a switch block and a pendulum connected to the switch block through a compression spring. The switch block is movably arranged on a switch socket; a receiving cavity matching the outer diameter of the compression spring is provided on the switch block. When the switch block moves, the compression spring is axially deformed on the receiving cavity, and the pendulum swings.
[0006] A convex block is provided on the swing piece, and the convex block is inserted into the inner cavity of the compression spring to realize the transmission connection between the switch block, the compression spring and the swing piece; and when the switch block is moving, the compression spring and the swing piece move asynchronously.
[0007] The inner diameter of the compression spring cavity is d1, and the radial dimension of the protrusion inserted into the compression spring cavity is d2, d1>d2, so that a loose fit gap is left between the protrusion and the inner cavity of the compression spring, and the compression spring and the pendulum have no interference fit (loose fit). During the movement of the switch block, the compression spring and the pendulum move at different frequencies, reducing the force of the pendulum assembly hitting the static contact of the L-pole assembly, thereby reducing the switching sound. Because the compression spring and the pendulum assembly have no interference fit, if the pendulum and the static contact are worn due to contact, the pendulum will automatically adjust the angle. When the switch block is in the open position, the pendulum always keeps in contact with the static contact of the L-pole assembly, so the switch performance is greatly improved.
[0008] When the swing piece swings, the convex block limit swings on the inner cavity of the compression spring.
[0009] There is a clearance fit between the compression spring and the accommodation cavity, and the outer peripheral side of the compression spring is close to the inner peripheral side of the accommodation cavity. During the movement of the switch slider, the compression spring only makes an axial deformation movement in the accommodation cavity.
[0010] Both ends of the compression spring are provided with flat portions. The flat portion at one end of the compression spring abuts against the top wall of the accommodation cavity of the switch slider, so that the compression spring only makes an axial deformation movement in the accommodation cavity.
[0011] The small sound swing piece switch structure further includes a static contact piece. The switch slider has an open position state and a closed position state on the switch socket, and the switch slider is switched to the open position state and the closed position state through movement;
[0012] When the switch slider moves to the open position state, the swing piece contacts the static contact piece;
[0013] When the switch slider moves to the closed position state, the swing piece disengages from the static contact piece.
[0014] The static contact piece is provided with a static contact point, and the swing piece is provided with a moving contact point. The moving contact point contacts or disengages from the static contact point of the static contact piece as the swing piece swings, realizing the on-off function of the switch socket.
[0015] The static contact piece is arranged on the static contact piece fixing seat, and the static contact piece is connected to the static contact piece fixing seat by plugging; the static contact piece fixing seat is fixed on the inner cavity of the switch socket.
[0016] There is a common terminal fixing seat on the inner cavity of the switch socket. The common terminal fixing seat is provided with a supporting block for supporting the bottom of the swing piece. The supporting block is provided with a plurality of convex strips arranged at intervals, reducing the frictional contact force between the supporting block and the bottom of the swing piece and further reducing the switch sound.
[0017] The beneficial effects of the present utility model are as follows:
[0018] By reducing the size of the inner cavity of the switch block that accommodates the compression spring, the compression spring only performs axial deformation movement (compression, releasing elastic force, etc.) in the cavity, and the interference fit structure between the compression spring and the pendulum is eliminated. During the movement of the switch block, the compression spring and the pendulum move at different frequencies (asynchronous movement), reducing the force of the pendulum hitting the static contact of the L-pole assembly, thereby reducing the switching sound. The compression spring and the pendulum have no interference fit (loose fit). During the movement of the switch block, the compression spring and the pendulum move at different frequencies, reducing the force of the pendulum assembly hitting the static contact of the L-pole assembly, thereby reducing the switching sound. Because the compression spring and the pendulum assembly have no interference fit, if the pendulum and the static contact are worn due to contact, the pendulum will automatically adjust its angle. When the switch block is in the open position, the pendulum always keeps in contact with the static contact of the L-pole assembly, so the switch performance is greatly improved.
