Description

  The present invention relates to an electronic switch member having a ceramic composite material, and can be applied to an electronic member capable of controlling the opening and closing of a circuit in an electronic device. The feature thereof is that a spark that generates a current touches a non-metallic part. In addition, the influence of current on the entire operation due to melting of non-metallic parts and generation of coke is reduced, and the invention is excellent in practicality.

A basic element, usually packaged separately and having two or more leads or metal contacts. Electronic members are connected to each other and need to constitute an electronic circuit having one specific function, for example, an amplifier, a wireless receiver, an oscillator, etc. One of the common ways of connecting electronic members is to print It is welded onto the circuit board. Electronic components can be single packages (resistors, capacitors, inductors, transistors, diodes, etc.) or groups of varying complexity, eg integrated circuits (operational amplifiers, exclusions, logic gates, etc.), and many Electronic members include terminals and connectors (devices used for circuit connections), cables (used to connect interfaces or terminations), switches (electronic members that can control circuit on / off), resistors (resistor electronic members) ), Protection devices (passive members that protect the circuit from too high voltage or current), capacitors (members that store charge in the electric field, capacitors are used as filters in the circuit, capacitors change the alternating voltage that normally passes through , Constant DC voltage does not change), electromagnetic induction device (using magnetic electronic material), network ( Composite circuit members configured using several or many types of passive members), memristors, piezoelectric devices and crystal resonators (passive members using the piezoelectric effect), power supplies (current supply sources), sensors, etc. .

  Most of the above electronic components are packaged by synthetic resin (resin dispensing). Especially, electronic components such as switches improve insulation and protect them from being affected by the environment, but they are energized. In addition to generating a spark when separating both conductive ends, the spark causes damage to the electronic member. Further, the outer shell after completion of the package in the electronic member is a plastic case, for example, a relay, each electronic member The appearance of many electronic components such as outlets and timers is covered with a plastic case, so the occurrence of sparks easily causes the plastic case to melt and coke, and many fire factors can also cause Insulating properties can be improved by using a synthetic resin package, but the material generates sparks and flames. However, this causes deterioration of the synthetic resin, making it impossible to achieve a high insulation effect, and eventually igniting, causing a problem of destroying the plastic case and internal components.

  In view of the above situation, the present inventor has invested a lot of time in researching related knowledge, comparing the superiority and inferiority of each item, conducting research and development of related products, and after many experiments and tests, finally `` ceramic composite "Electronic switch member with material" has been developed to solve the above defects and meet the demands of mass use.

  In order to make the above object, structure and features of the present invention deeply and concretely understandable, the technology, means and effects adopted by the present invention will be described in detail below with reference to the accompanying drawings. The following is a description of a preferred embodiment and does not limit the present invention in any form. As shown in FIGS. 1 to 12, an electronic switch member having a ceramic composite material of the present invention includes: The first combination part 11 and the second combination part 12, and a storage chamber 13 is formed inside the first combination part 11 and the second combination part 12, and the second combination part 12 has a bottom plate 121 and the shell 1 having two frame plates 122 standing upright on one side of the bottom plate 121 and the inside of the housing chamber 13 and attached to the second combination unit 12 to control the on / off of the circuit board. A detent component assembly 2 used to do and an insulating composite material 3 attached to a surface on one side corresponding to the storage chamber 13 of the second combination portion 12, The edge composite 3 isolates the contact between the second combination part 12 and the detent assembly 2 (this is the main technical feature of the embodiment of the present invention, which is defined in the first claim of the present application). Corresponding to the contents, the object and embodiments of the present invention can be understood in detail, and the technical features described in the remaining dependent claims are the details or additional techniques to the contents of the claims. It is a characteristic and does not limit the scope of limitation of the first claim, and the first claim of the present invention does not necessarily include the technical features described in the dependent claims. ).

  Common electronic switch members are used to control the on or off of a circuit, in short, they are like starters, and there are several types of electronic switch members that are commonly found: Switch: A manually operated switch. Second, Keypad: A group of button switches (for example, a small keypad that can input only numbers). 3. Relay: A current-operated switch is an electromagnetic member having a solid state relay. 4. Electromagnetic switch (Contactor). 5. Automatic thermostat (Thermostat): Automatic temperature control switch. 6. Circuit Breaker: Overcurrent automatic breaker switch. 7. Limit switch: A mechanical start switch. Eight, switch (Mercury switch). 9. Centrifugal switch. 10. Connector. Some of the above are related electronic switch members that are often used on circuit boards in current precision instruments, but the joint properties of these electronic switch members all have a plastic outer shell, and therefore are internal. It is easy to generate a spark when the conductive ends are separated and the conductive ends are separated. The spark is generated at an extremely high instantaneous high temperature, which causes melting of low-melting plastic products and coke. Therefore, using the installation of the insulating composite material (3) of the present invention, the detent component assembly 2 and the first and second combination parts 11 and 12 having a low melting point are blocked by using the attachment of the insulating composite material (3) of the present invention. In this way, the spark does not directly touch the first combination unit 11 and the second combination unit 12 and does not cause a disaster.

  There are two types of installation forms of the insulating composite material 3 of the present invention. The first type of the insulating composite material 3 is a single piece, and the single piece is formed using ceramic as a main material.

And the influence of the sparks on the second combination part 12 is reduced. (Of these, the covering form of the insulating composite material 3 can be changed according to the form of the bottom plate 121 and the frame plate 122. Not restricted). Also, as shown in FIGS. 10 to 12, the illustrated insulating composite material 3 does not cover the frame plate 122 on the bottom plate 121, and thus opens two hole strips 31 on the insulating composite material 3 of the lid, Therefore, the frame 122 positioned on the bottom plate 121 passes through the two hole strips 31 of the insulating composite material 3, and then attaches the insulating composite material 3 to the surface of the bottom plate 121. Subsequently, as shown in FIGS. 7 to 9, the insulating composite material 3 is applied to the outer surfaces of both the frame plate 122 and the bottom plate 121 of the second combination unit 12, and the bottom plate 121 and the frame plate 122 are further attached. Fully covers and ensures that the contact between the detent assembly 2 is separated from the bottom plate 121 and the frame plate 122. The description of the three examples given above is for the purpose of a second made of plastic. The combination part 12 and the detent part assembly 2 are separated from objects that easily generate sparks, reducing the occurrence of coke and melting of the second combination part 12 made of plastic, and the insulating composite 3 The form which covers 2 combination part 12 is not restrict | limited to said each Example, Does it cover the location which is easy to generate | occur | produce a spark in detent part assembly 2 of 2nd combination part 12? Can be applied protecting, three types of embodiments described above is only described just shows a preferred embodiment.
