Embodiment

Below in conjunction with drawings and Examples the utility model is further described.

As shown in Figure 1, form by male contact and famale connector cooperation; When not making electrical appliance, male contact 2 and famale connector 1 separate.

As shown in Figure 2, described male contact 2 lower ends vertically are arranged with fire line terminal 2-1, zero terminal 2-2 and earth terminal 2-3 at grade successively, a groove 2-4 is respectively arranged between fire line terminal 2-1 and zero terminal 2-2 and the earth terminal 2-3, and this groove 2-4 is provided with engaging of famale connector 1 for convenience.

As Fig. 2, Fig. 3, Fig. 4, shown in Figure 5 as described in famale connector 1 comprise pedestal 3, rotating plate 4 and torsion spring 5, the major axis 4-3 of both sides, rotating plate 4 rear end matches with the installing hole 3-2 of pedestal 3 rear upper end both sides, torsion spring 5 is enclosed among the minor axis 4-4 on the gusset 4-5 of rotating plate middle part, one wing of torsion spring 5 is close to the rear wall 3-7 of pedestal, another wing is close to the lower surface of the top board 4-1 of rotating plate 4, and torsion spring 5 produces the moment that rotating plate 4 is up lifted.

As shown in Figure 3, be the oblique view of famale connector 1.Famale connector 1 mainly is made up of pedestal 3, rotating plate 4, torsion spring 5 and live wire sheet spring, zero line sheet spring, ground strip spring 6.From in appearance, can only see pedestal 3 and rotating plate 4.

As shown in Figure 4, be the oblique view of the pedestal in the famale connector 1.Famale connector 1 is surrounded by the antetheca 3-8 that is perpendicular to one another, rear wall 3-7 and two introversion sidewall 3-1.Wherein antetheca 3-8 is the shortest, and rear wall 3-7 is high slightly, and the front end of introversion sidewall 3-1 flushes with antetheca 3-8, and the rear end is than rear wall 3-7 height.The latter half of introversion sidewall 3-1 is vertical, and the first half is to the inner inclination of pedestal 3.On the top, rear portion of two introversion sidewall 3-1 an installing hole 3-2 is arranged respectively, be used to install rotating plate 4; On the top, middle part of two introversion sidewall 3-1 a spacing round platform 3-3 is arranged respectively, be used to limit the maximum displacement that rotating plate 4 makes progress.

The coffin that is surrounded by antetheca 3-8, rear wall 3-7 and two introversion sidewall 3-1 is divided into three chambers by two partition wall 3-7 that are arranged in parallel of its inside, middle chamber is used to install ground strip spring 6, and the chamber of both sides is respectively applied for installs live wire sheet spring and zero line sheet spring.Upper right side at two partition wall 3-5 respectively has a v type breach 3-6, the right-hand part of v-notch 3-6 is a cambered surface, inswept track when cooperating the rotation of rotating plate 4 ends, the left side of v-notch 3-6 is a flat face, the lower limit pad platform that is rotated down under external force as rotating plate 4.

There is an intilted spacing sloping platform 3-4 upper end, base front wall 3-8 middle part, the guiding when inserting as male contact 2, and prevent that male contact 2 is because of patching too quickly slippage.

As shown in Figure 5, be the end view of rotating plate 4, this rotating plate 4 is made up of top board 4-1, major axis 4-3, back plate 4-2, gusset 4-5 and minor axis 4-4.Major axis 4-3 matches with installing hole 3-2 on the pedestal 3, when rotating plate 4 is installed, major axis 4-3 is inserted among the installing hole 3-2.Top board 4-1 is used to block the top of pedestal 3, and back plate 4-2 is used to block the upper back of pedestal 3.Gusset 4-5 plays booster action, and minor axis 4-4 is also attached to above it.Described minor axis 4-4 is used to install torsion spring 5.Described rotating plate 4 front center have a thickened area 4-6, mainly bear stressed in the electric connector engaging process.In the electric connector engaging process, the earth terminal 2-3 of male contact at first contacts with thickened area 4-6 on the rotating plate 4 and promotes rotating plate and rotates.

Famale connector 1 cutaway view when not inserting as shown in Figure 6, for male contact 2.This section is the left-right symmetric two halves with famale connector 1 subdivision, also ground strip spring 6 subdivisions is opened.The assembly relation of pedestal 3, rotating plate 4, torsion spring 5 as can be seen therefrom.The major axis 4-3 of both sides, rotating plate rear end matches with the installing hole 3-2 of pedestal rear upper end both sides, torsion spring 5 is enclosed within on the minor axis 4-4 of rotating plate middle part gusset 4-5, one wing of torsion spring 5 is close to the rear wall 3-7 of pedestal, another wing is close to the lower surface of the top board 4-1 of rotating plate, produce the moment that rotating plate 4 is up lifted and upwards rotate, but the maximum displacement of upwards rotating is subjected to the restriction of introversion sidewall 3-1 upper limit round platform 3-3.At this moment, rotating plate 3 just in time seals the top of pedestal.

As shown in Figure 7, insert back famale connector 1 cutaway view for male contact 2.In Fig. 7, male contact 2 inserts, pressing down rotating plate 4 down rotates it along clockwise direction, just expose one slit this moment, earth terminal 2-3 in the male contact 2 at first puts in slit and connects with the ground strip spring 6 in the famale connector 1, afterwards similarly, the fire line terminal 2-1 on the male contact 2, zero terminal 2-2 also respectively with famale connector 1 in live wire sheet spring, zero line sheet spring connect (not shown), thereby connect circuit.

After the user uses electrical equipment, electrical equipment is extracted from famale connector 1 together with male contact 2, rotating plate 4 is subjected to the elastic-restoring force effect of torsion spring 5 and up lifts in the counterclockwise direction, and be subjected to the restriction of spacing round platform 3-3 and reach balance, just cover in pedestal 3 this moment again, with wherein circuit and the external world separates, play security protection and be used for.
