Push switch

The present invention provides a push switch, in particular, a recessed groove is formed in the seat of the push switch, and the button in the receiving groove can be used for sliding displacement of the button of the pressing component, thereby reducing the thickness of the wall surface of the seat body to make the overall height It is reduced and thinner, and the terminal seat is combined with the terminal seat on the back side, and the outer cover is combined with the metal casing to enhance the overall stable support and structural strength.

According to the advent of the high-tech era, various electronic products are widely used in daily life and work, and improve the efficiency and convenience of life and work. However, in addition to indoor use, various electronic products have many Electronic products are portable and unconstrained and limited by time. For example, notebook computers, tablet computers, multimedia audio and video players, mobile phones, digital cameras, etc. are all electronic products that can be carried and used with them. The design of electronic products is designed in the direction of light, thin, short and small. The various components used in electronic products are also reduced and lightened to meet the small size and convenient portability of electronic products. mode.

Among the components used in various electronic products, the push switch is a commonly used component, which is controlled by pressing, and is easy to be mass-produced due to the simple overall structure, so it is widely used. In electronic products, such as wireless remote control, digital walkman, etc. currently on the market, and with the rapid development of technology, it will switch A light-emitting element is mounted on one side, and during the electrical switching process of the switch, the light-emitting element can simultaneously switch the light, so that the user can clearly understand the switching state of the switch.

However, the conventional side-press type lamp pressing open relationship includes a body, a touch button on the front and rear sides of the body, and a terminal group, and the light-emitting diodes positioned on the front side of the body are extended on the two sides and extend backwards. The second extending leg forms a vertical pin downwardly from the bent portion on the rear side, and has a horizontal section and a vertical section on the terminal group, and forms a bent portion at the joint of the horizontal section and the vertical section to enable the light emitting diode The vertical pin of the body 2 and the vertical segment of the plurality of terminal pins respectively correspond to the position of the joint soldered on the circuit board, and when the front side touches the button to press the body, the terminal group in the body is converted from the original open circuit to the closed circuit electrical property. The connection state triggers or transmits a control signal to cause the light-emitting diode to generate a bright light projection. However, when the touch button is pressed, there is no support structure fixed on the rear side of the body, so that the body is likely to be lifted up and down. When the shaking occurs, it is not easy to make the touch button and the terminal group accurately align, and the overall structure is also quite unstable, and may even cause the vertical section of the terminal group to be pushed up. Excessive deformation or structural damage, and excessive deformation of the terminal group will cause damage or peeling of the solder structure on the circuit board, resulting in problems such as poor electrical contact, short circuit or interruption of signal connection, and development due to thinning As a result, the structural strength of the body itself is insufficient, and the user is constantly reciprocatingly pressed, which easily causes a problem of structural deformation or destruction of the switch body.

Therefore, how to solve the above problems and shortcomings in the past is the direction for the relevant manufacturers engaged in this industry to research and improve.

Therefore, in view of the above-mentioned deficiencies, the creators have collected relevant information, evaluated and considered through multiple parties, and continued to try and modify through years of experience in the industry. A new patenter of this type of push switch was designed.

The main purpose of the present invention is to provide a receiving groove on the front side of the body of the body, and two parallel connecting terminals are arranged on the rear side of the body, and the elastic piece and the button of the pressing component are sequentially installed in the receiving groove. And the front side of the button is concavely provided with a space for the light-emitting element to be placed, and the two sides of the light-emitting element are provided with an extension body extending outward and extending rearward to the extension legs on both sides of the body, and the end of the extension leg is bent downward. The soldering leg is further combined with a terminal block on the rear side of the body, and the two sides of the base are respectively provided with perforations for the two soldering legs to penetrate, and extend in the same direction on the two sides of the base to resist the body. The side arm can be covered with a metal shell on the outer side of the body, and has a base portion abutting against the upper portion of the body, and the two sides of the base portion are bent and extended to abut the side plates of the two sides of the body, and then the side plates are facing The lower protruding portion is provided with a positioning pin, and the above structure can make the button slide and displace in the receiving groove of the seat body, thereby reducing the thickness of the body wall surface, and when used with a broken board-shaped preset circuit board, Make the overall height further reduced and thinner, Slim and light design products in line with demand, thus achieving the purpose of increasing the competitiveness of their products.

The secondary purpose of the present invention is that the soldering leg of the light-emitting component of the pressing component and the positioning pin of the metal casing are soldered on the circuit board, and when the front-side pressing component is pushed and pressed, the terminal body can utilize the terminal block and the metal shell. The body is stably supported to prevent the welding foot from being pushed, resulting in bending deformation of the vertically bent portion, causing the solder on the circuit board to be peeled off, forming problems such as poor contact, short circuit of electrical connection, interruption, etc., thereby increasing the product. The service life.

Another purpose of the present invention is that the metal casing forms a grounding function with the circuit board by the two positioning pins to smoothly remove interference signals such as noise or electromagnetic waves, thereby further transmitting signals between the connection terminals of the base body and the circuit board.
