Description

Technical Field

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

[0002] Currently, commercially available mosquito swatters typically consist of a mosquito net, a handle, a boost circuit, and a power supply. The power supply provides sufficient voltage to the mosquito net through the boost circuit. A control switch is connected in series between the power supply and the boost circuit. A key feature is that a manually controlled power-off protection device for the mosquito net is connected in series between the boost circuit and the mosquito net. Users can manually disconnect this device to instantly and completely disconnect the mosquito net from the external circuit (boost circuit), ensuring that there is no residual power in the net after disconnection. This significantly improves the safety of using the electric mosquito swatter without reducing the product's power consumption. Furthermore, because the disconnection operation is performed manually, users can more intuitively experience the safety of the mosquito net, eliminating concerns about the safety of the electric mosquito swatter and further promoting its adoption. This also extends the product's lifespan.

[0003] However, the existing electric mosquito swatters still have the following shortcomings: (1) The control switch of the electric mosquito swatters is a slider-type push-pull switch. After use, users may forget to turn it back to disconnect the power supply (disconnect the boost circuit); (2) The control switch has a short service life, is difficult to operate, and has a high failure rate.

[0004] Therefore, this application designs a micro switch that can be used on mosquito swatters. It is smooth and convenient to operate and can quickly and efficiently switch the conduction of high-voltage circuits and low-voltage circuits. Utility Model Content

[0005] The purpose of this invention is to provide a micro switch that is simple and reasonable in design, stable and reliable in operation, and can quickly and efficiently switch the conduction of high-voltage circuits and low-voltage circuits.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] A micro switch includes a base, a button, a spring, a reed, a normally closed terminal, a floating pressure block, a normally open terminal, a contact spring, a low-voltage end bracket, a high-voltage end spring bracket, a cover plate, and a partition cable tray.

[0008] The base is a shell with an opening at the top and an inner cavity in the middle, and has claws at both the left and right ends;

[0009] The cover plate has slots at both ends, which are adapted to the claws; the cover plate is placed on the upper end of the base and is snapped together with the base, and the slots are connected to the claws.

[0010] The partition bridge is arranged in the inner cavity of the base, and divides the inner cavity into two parts, i.e., the upper low-voltage passage accessory installation area and the lower high-voltage passage accessory installation area.

[0011] The upper end of the base is provided with a sliding groove for mounting a button, and the button is arranged in the sliding groove and movably connected with the sliding groove.

[0012] The inner side of the low-voltage end support, the spring, the reed, and the inner side of the normally closed terminal are arranged in the low-voltage passage accessory installation area.

[0013] The high-voltage end reed support, the normally open terminal, and the contact bridge reed are arranged in the high-voltage passage accessory installation area.

[0014] The low-voltage end support comprises a support main body, a wiring pin, a spring hanging plate, a reed hinged plate, and a spring displacement cavity. The bottom end of the support main body is provided with the wiring pin, and the upper end is provided with the spring hanging plate and the reed hinged plate at intervals. The spring hanging plate is provided with a hook hole and a displacement hole. The left end of the reed is hingedly connected with the reed hinged plate. The middle section of the reed is provided with a hook hole. The left and right ends of the spring are connected with the hook holes on the spring hanging plate and the reed, respectively. The support main body is further provided with a spring displacement cavity for giving the spring a displacement space when the spring is pressed down and moved down, so as not to block the spring. The spring displacement cavity is directly below the spring. The pressing rod is directly above the spring, and the bottom of the pressing rod is in close contact with the spring. Preferably, in order to prevent the spring and the pressing rod from being stuck and interfering with each other, the bottom of the pressing rod is a V-shaped inclined surface.

[0015] The low-voltage end support, the reed, and the normally closed terminal are made of metal conductive material.

[0016] The middle part of the reed hinged plate is further provided with a spring displacement hole.

[0017] Preferably, in order to better realize circuit communication, one side end of the reed, the normally closed terminal, the normally open terminal, and the contact bridge reed is provided with a metal contact. The metal contact can be a rivet.

[0018] The high-voltage end reed support comprises a wiring pin and a reed hanging column. The lower end of the contact bridge reed is provided with a mounting hole, and the mounting hole is sleeved on the reed hanging column. The lower end of the contact bridge reed is vertically arranged, and the upper end is obliquely arranged upward. The left end of the normally open terminal is arranged below the right end of the contact bridge reed. The partition bridge is provided with a sliding cavity for mounting a floating pressing block, and the floating pressing block is arranged in the sliding cavity and slidably connected with the sliding cavity. The bottom of the floating pressing block is in close contact with the top surface of the right end of the contact bridge reed. The floating pressing block is made of insulating material.

[0019] Briefly describe its working principle:

[0020] The contact spring has a certain elastic deformation property. In its natural state, its right top surface is in contact with the bottom of the floating pressure block, and its right bottom surface is separated from the normally open terminal by a gap. When the button is pressed down, the pressure rod pushes the spring, and the right end of the spring is pressed down, causing the hinged spring to swing downward. The right end of the spring touches the floating pressure block, which presses down on the contact spring, making the contact spring fit with the normally open terminal, forming a "wire" connection. When the button is released, the spring returns to its original position, the spring is pulled to the left, and it swings upward, no longer applying pressure to the floating pressure block. The contact spring returns to its original shape, moves upward, and disconnects from the normally open terminal.

[0021] The beneficial effects of this utility model are:

[0022] Its design is simple and reasonable, its operation is stable and reliable, and it can quickly and efficiently switch the conduction of high-voltage circuits and low-voltage circuits.

[0023] The structural design, installation, and limiting methods of normally closed terminals, normally open terminals, high-voltage end spring clip brackets, and low-voltage end brackets ensure that their installation positions are stable and reliable. Attached Figure Description
