Description

Socket or switch

This case relates to the various sockets of grid power power supply, coax signal cable, computer network cable or the external member of switch, is called for short member.Described member is made of base and panel, its member, and minimum can be transportable, also can be fixed on furred ceiling, metope, ground, desktop, electrical equipment or other object.

Known members is usually by made such as plastics, resin, rubber, only the base of indivedual kind socket panel inside is potteries, by true, more do not have panel and base and adopt exotic material simultaneously the investigation of the new old product of part on the U.S., Japan and a large amount of domestic market.As plug or the long-time big current work of switch, and the starting current of perceptual electrical equipment more than tens times, the big electric current that also has the electrical equipment abnormal failure to cause, the high temperature that is produced all can make panel and base temperature distortion, even burned generation disaster hidden-trouble.

If breaking out of fire in addition, usually because member partly or entirely adopts plastics, resin, elastomeric material, not only calorific capacity adds ' material ' on higher and fiery, and, the smoke density that the burning back produces is higher, and toxicity such as the chlorine molecule in the cigarette are bigger, unfavorable safe, unfavorable health, unfavorable environmental protection.For preceding surface member, fired and from continuing damage electric wire within the walls then.

Beijing national quality supervision and inspection on the 7th in May calendar year 2001 epidemic disease general bureau of ginseng Xinhua News Agency has carried out random checking to family expenses and similar applications plugs and sockets product quality, in 93 kinds of products of selective examination, and 37 kinds of fixed sockets, the sampling qualification rate is 45.9%; 11 kinds of mobile sockets, all defective.

Ginseng C1 version in 2 days " Yangzi Evening " March calendar year 2001,268 of Nanjing appliance fires in 2000 lose 207.9 ten thousand yuan, account for 34.4% and 54.3% of fire sum respectively, and appliance fire has become leading cause of fire.

Ginseng display in 22 days " Computer Business Information " June calendar year 2001 uses to be introduced, and the power supply of display will directly be inserted on the independent on the wall socket, and avoids being inserted on the mobile socket as far as possible.Tend to cause monitor power supply bad with mobile socket, screen shake, screen lines, neglect dark bright suddenly even blank screen and all might cause by power supply.Line plate inferior also can burn display, in fact, the breaking-up of a lot of displays all be since the socket institute that uses extremely.

Known technology has partial portion to adopt glass or pottery to constitute, and all uses plastics, resin, rubber usually, and the product difficulty improves grade.

This case purpose:, satisfy needs of society for people improve safer, the electric product of high gear more.

This case method:, comprise that the jack of the latch insertion socket panel of plug all adopts exotic material on every side for the position of the supporting close metal fittings of member.1. can base and panel all with glass or pottery, same material, 2. can base and panel respectively with glass or pottery, foreign material, 3. in order to improve the class of product, can also adopt fully or, partial portion adopt or, a small amount of position adopt remove glass and ceramic high-temperature insulation material.

This case is owing to the exotic material that adopts, and hardness is all higher, but fragility is bigger, can consider that for the bump that reduces panel damages the place ahead at panel is provided with the translucent cover of pin hole.

This case is because the exotic material that adopts, and hardness is all higher, but fragility is bigger, and present electric wire is more and more thicker along with the increase of power consumption, when preventing that socket from installing, and supporting sleeve damaged member under the promotion of thick electric wire, this case has designed through wires hole.When electric wire is connected to sleeve, passes the through wires hole of member earlier, and then the electric wire copper core that end is peeled off the ambroin sheath is fixed to the binding post of member.

So the behind of this case member, the rarest one or more area is 4～7mm ², contain 7mm ², or, 7～12mm ², contain 12mm ², or 12～21mm ², contain 21mm ², or,＞21mm ²Through hole.

This case is because the exotic material that adopts, and hardness is all higher, but fragility is bigger, and in order to reduce the small structure of member, we can be with the panel of the bigger direct strain component of nuts of head.

6. according to claim 2, described ' high-temperature insulation material except that glass and pottery ', be meant material lasting thermal endurance or, in short-term thermal endurance or, fusing point or, molten point or, glass transition temperature or, heat distortion temperature or, serviceability temperature or, heat resisting temperature or, the Martin heat resistance temperature or, dimension card inversion point or, the load deformation temperature, its value is the rarest to be 301 ℃～500 ℃ more than one or one, contain 500 ℃ or, 500 ℃～800 ℃, contain 800 ℃ or,＞800 ℃.

Ginseng " 384～522 pages of electrical material handbook, China Machine Press, in February, 1999 and " low-voltage electrical apparatus design manual " 242～273 pages, China Machine Press, in May, 1993, at present, make the bakelite that low-voltage electrical apparatus is used, plastics, resin, rubber insulation material is selected lasting thermal endurance usually for use, or, thermal endurance in short-term, or, fusing point, or, molten point, or, glass transition temperature, or, heat distortion temperature, or, serviceability temperature, or, heat resisting temperature, or, the Martin heat resistance temperature, or, dimension card inversion point, or, the load deformation temperature, the reflection heat resistance, it is worth all＜300 ℃.

Described high-temperature insulation material, be meant material lasting thermal endurance or, in short-term thermal endurance or, fusing point or, molten point or, glass transition temperature or, heat distortion temperature or, serviceability temperature or, heat resisting temperature or, the Martin heat resistance temperature or, dimension card inversion point or, the load deformation temperature, its value is the rarest to be 301 ℃～500 ℃ more than one or one, contain 500 ℃ or, 500 ℃～800 ℃, contain 800 ℃ or,＞800 ℃.
