Description

Technical Field

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

[0002] Pushbutton switches, as common control components in electronic devices, are widely used in various electrical and electronic equipment, such as home appliances, industrial control, and automobiles. With the development of technology and the continuous expansion of application scenarios, the performance and functional requirements for pushbutton switches are becoming increasingly stringent. Traditional pushbutton switches have complex structures, are cumbersome to assemble, and have limited lifespans. Switches using a single dome spring, in particular, are prone to wear after prolonged use, leading to a shortened lifespan and inability to meet the demands of high-frequency use. Therefore, a new type of pushbutton switch with a simple structure and long lifespan is needed. Summary of the Invention

A push rod is fixedly connected to the bottom of the button. The bottom of the rubber head is engaged with a rubber base. Two terminals are provided inside the rubber base. A contact piece is provided above the terminal, and a spring piece is provided above the contact piece. When the rubber head is pressed, the push rod presses down the spring piece, so that the contact piece engages with the two terminals to conduct the circuit.

[0005] Preferably, a buckle is provided on the outer side of the rubber head, and the buckle is connected to the slot of the rubber seat to form an engaging structure.

[0006] Preferably, the adhesive base has a first terminal slot and a second terminal slot inside, and a boss is provided inside the adhesive base, and the first terminal slot, the second terminal slot and the boss are protruding inside the adhesive base.

[0007] Preferably, the terminal includes a first terminal and a second terminal, and the first terminal and the second terminal are respectively connected through the first terminal slot and the second terminal slot. The first terminal has two pins on both sides, and a conductive slot is formed in the middle of the first terminal. The second terminal is located inside the conductive slot and below.

[0008] Preferably, the contact piece has an arc-shaped hollow structure, and movable pieces are provided on both sides of the middle part of the contact piece, which contact the second terminal below when pressed down.

[0009] Preferably, the spring sheet has an arc-shaped structure, and the spring sheet matches the contact sheet.

[0010] Preferably, the adhesive base has a protruding post inside, and the protruding post is fitted and connected to the groove opened on the outside of the adhesive head.

[0011] The beneficial effects of this utility model are as follows:

[0012] This device is assembled from components such as rubber base, terminals, contact pieces, springs, and buttons. It has a simple structure, is easy to assemble, and reduces production difficulty.

[0013] The separate design of the contact piece and the spring reduces wear on individual components and extends the service life to 1 million cycles, far exceeding that of ordinary switches that use only a dome switch. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-6This utility model provides a technical solution: a simple long push button switch, including a rubber head 1, a button 201 connected to the top of the rubber head 1, and the button 201 and the rubber head 1 are an integral structure. A push rod 202 is fixedly connected to the bottom of the button 201. The bottom of the rubber head 1 is engaged with a rubber base 2. The rubber base 2 has two terminals inside, a contact piece 5 is provided above the terminals, and a spring piece 4 is provided above the contact piece 5. When the rubber head 1 is pressed, the push rod 202 presses down the spring piece 4, so that the contact piece 5 engages with the two terminals to form a conductive circuit. A buckle 3 is provided on the outside of the rubber head 1, and the buckle 3 is connected to the slot opened in the rubber base 2 to form an engaging structure. A protrusion 10 is provided inside the rubber base 2, and the protrusion 10 is fitted into the slot opened on the outside of the rubber head 1.

[0023] In practice, when assembling this device, it is only necessary to fit the rubber head 1 into the rubber base 2. The buckle 3 on the outside of the rubber head 1 will fit into the slot on the outside of the rubber base 2, and the protrusion 10 inside the rubber base 2 will also fit into the slot on the outside of the rubber head 1, which helps to fix the device and greatly reduces the difficulty of installation.

[0024] Please see Figures 2-4 The adhesive base 2 has a first terminal slot 8 and a second terminal slot 9 inside, and a boss 203 inside the adhesive base 2. The first terminal slot 8, the second terminal slot 9 and the boss 203 are protruding inside the adhesive base 2. The terminals include a first terminal 6 and a second terminal 7, and the first terminal 6 and the second terminal 7 are respectively connected through the first terminal slot 8 and the second terminal slot 9. The first terminal 6 has two pins on both sides, and a conductive groove is opened in the middle of the first terminal 6. The second terminal 7 is located inside the conductive groove and below. The contact piece 5 has an arc-shaped hollow structure, and movable pieces are provided on both sides of the middle part of the contact piece 5. When the movable pieces are pressed down, they contact the second terminal 7 below. The spring piece 4 has an arc-shaped structure, and the spring piece 4 matches the contact piece 5.

[0025] In specific implementation, when setting up the conductive circuit, firstly, by pressing the button 201 connected to the top of the rubber head 1, the button 201 moves downward, driving the push rod 202 to move. At this time, the spring 4 connected to the pushing end of the push rod 202 will contact the contact piece 5 on the top of the first terminal 6, and the contact surface of the spring 4 matches the contact piece 5. The spring 4 will squeeze the contact piece 5, and through the first terminal groove 8, the second terminal groove 9 and the boss 203 provided around the first terminal 6, the contact piece 5 is subjected to uniform force and will not be excessively deformed. This helps the contact piece 5 at the top of the first terminal 6 to connect with the second terminal 7, and the second terminal 7 is located directly below the conductive groove in the middle of the first terminal 6, so that a circuit is formed between the two terminals, completing the opening and closing of the conductive circuit. When disconnecting, simply release the pressed button 201. At this time, the button 201 will retract, driving the push rod 202 and the spring piece 4 back to the initial position, so that the contact piece 5 is no longer squeezed and restores its deformation. The contact piece 5 is disconnected from the second terminal 7, so that the conductive circuit mechanism is disconnected and the power is cut off.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
