CN1870352A - Self-fastening safety power socket - Google Patents

Abstract

This invention relates to a safety supply socket in an insulation shell, the copper plates of which are hinged on the shell by pins, a spring is stuck between the bottom of the copper plate and the shell and connected with the supply, the copper plates are divided in pairs and the distance between them is a bit smaller than the thickness of the plug, when the socket does not work, the plates are close together by the spring with an open-end at the top, when a plug is plugged and arrives at the bottom of the socket, the plates of the socket will be open, then the top will tightly press the plates of the plug to contact tightly and increase the contact area effectively.

Description

Self-fastening safety power socket

Affiliated technical field

The present invention is a kind of supply socket that has new structure, high reliability and high security.

Background technology

Supply socket is one of requisite electrical home appliances of Modern Family, and nearly all electrical equipment all will be used socket.And along with the people that improve constantly of household electrical appliances class are also improving constantly the requirement of supply socket.For example powerful air conditioner, computer etc. are just very high to the requirement of power supply.Because the power of air-conditioning is all very big, operating current is also big, if the quality of socket does not pass a test, will be because of electric current make self hot greatly when air-conditioning work, and the lighter damages air conditioner, and serious may initiation fire.And the picture computer, if power supply loose contact when work can cause that computer restarts.This can allow your achievement be thrown into the eastward flowing stream, and more can cause irremediable economic loss.As for the commercial power supply socket. the quality of himself can't neglect especially.Because industrial power supply with high-power, often move and often plug be many, common socket useful life is short, easily send out accident.The socket that uses is owing to aspect reasons such as designs at present, and all there is above-mentioned defective in great majority.

Summary of the invention

In order to overcome the deficiency of existing power supply socket poor reliability poor stability, the invention provides a kind of supply socket, this supply socket can provide safe and reliable power supply for electrical appliance.

The technical solution adopted for the present invention to solve the technical problems is: in insulation crust, one group in twos of socket elastic copper sheet, one end is connected with power lead, its middle part perforate and shell are hinged, copper sheet should be able to carry out＜30 ° freely rotating around the hinged place, and a stage clip is installed between socket lower end and the shell.During non operating state, socket copper sheet its lower end under the effect of spring is close to together, upper end open, and opening size is about 3 millimeters.When the plug copper sheet inserted, the plug copper sheet strutted the socket copper sheet, and by lever principle as can be known, the plug copper sheet can be pressed in socket copper sheet upper end.And because the socket copper sheet upper end arm of force is the twice of the lower end arm of force, so the displacement of socket copper sheet upper end should be the twice of lower end, but the twice of the insufficient space lower end displacement of socket upper end, so the socket copper sheet can produce strain, form pressure and make the socket copper sheet tightly clamp the plug copper sheet.

The invention has the beneficial effects as follows: can effectively prevent situation appearance such as loose contact; Contact point is two to four times of common socket, and contact area is five to ten times of common socket, 1/3rd of the not enough common socket of the temperature rise that causes because of contact resistance when high power work.This shows that its reliability and fail safe all are the several times of common socket.

Description of drawings

The present invention is further described below in conjunction with accompanying drawing and example.

Fig. 1 is the three-view diagram of socket copper sheet among the present invention.

Fig. 2-Fig. 6 is the form of socket under various working methods.

Fig. 7 is the form of socket when operate as normal.

1. plug copper sheets among the figure, 2. socket copper sheet, 3. power line connection screw, 4. pin, 5. insulation crust, 6. spring.

Embodiment

Socket copper sheet 2 is hinged by pin 4 with insulation crust 5, and spring 6 is stuck between the lower end and insulation crust 5 of socket copper sheet 2, and in Fig. 1,3 places connect power supply; In Fig. 2, the position the when position is free state shown in the socket copper sheet; Figure 3 shows that the position when socket copper sheet upper end open is plug copper sheet thickness; Figure 4 shows that the lower end is subjected to spring force to be close to together position; Figure 5 shows that the position when socket copper sheet lower ending opening is plug copper sheet thickness; Position when Figure 6 shows that work.Can find out clearly that from Fig. 2 to Fig. 6 want in the plug copper sheet socket, the socket copper sheet must produce distortion, also just produce simultaneously and closely contacted required pressure between plug, the socket copper sheet.

Claims (2)

1. supply socket, socket contact copper sheet is the circular arc case of bending in insulation crust, and its two ends contact with the plug copper sheet, it is characterized in that: rod principle is shouldered in the utilization of socket copper sheet, and the socket copper sheet can produce strain when plug inserts, and two ends clamp the plug copper sheet.

2. supply socket according to claim 1 is characterized in that: the socket copper sheet can turn an angle, and when non operating state, socket copper sheet upper end is an opening, very helps plug and inserts.
