Abstract

The utility model relates to a three-wire electrical receptacle, particularly applicable to the transform receptacle of the connection of two plugs. The center of the top surface of the socket cover is parallel to the flat face of the bottom surface of the base and two inclined planes are the inclined plane faced outwards; the jacks provided with the same size and position of the jacks of the base are arranged on the inclined planes. Each plug is fixedly connected with a spring clamp directly. Both ends of the spring clamp have elastic clamp holes convex upwards which stretch at the lower part of the jacks of the socket cover; the inclination angle of the top end of the elastic clamp holes are uniform corresponding to the inclination of the socket cover. So two three-wire power source electric appliances can be turned on without using the patching board. The utility model has the advantages of shapely configuration, low cost, safety, and space saving.

Description

Polygon three-wire receptacle

The utility model relates to a kind of three-way electrical outlets, particularly is applicable to the conversion socket that two plugs connect.

At present, the plug of three-way power supply electrical equipment commonly used is directly to insert the wall mounted socket or in the three-plug connector of terminal block, but along with the household appliances increase day by day of three-way power supply, for example: refrigerator, refrigerator-freezer, lampblack absorber, electric heater etc., and the socket of wall is limited, though can arrange many group three-way jacks at terminal block, but, need occupy in addition, it is unreliable that electric wire connects, not attractive in appearance yet, and cost is also high.

The purpose of this utility model is that a kind of polygon three-plug connector will be provided, and can directly be inserted in the wall three-plug connector, uses for two three-way power supply appliance plugs.

The purpose of this utility model is achieved in that the end face centre of flap is the plane that is parallel to base end face, two inclined-planes are to face outer inclined-plane, on the inclined-plane, has jack with base jack same size and position, the every direct fixedly connected spring clip of plug, has resilient clip opening to upper process at the two ends of spring clip, stretch below the flap jack, and the angle of inclination, top of resilient clip opening tilts consistent with the inclined-plane of corresponding flap.After the plug of this three-plug connector inserted the wall three-plug connector, the plug of two household electrical appliance inserted the jack on two inclined-planes on the flap respectively, the clamped and direct energising of the resilient clip opening that extend into corresponding spring clip.

Owing to adopt such scheme, without terminal block (plug and the electric wire that comprise terminal block), the electrical equipment that can connect two three-way power supplys do not take up space in addition, without electric wire connect, safe and reliable, handsome in appearance, easy to use and with low cost.

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

Fig. 1 is the structural representation of an embodiment of the utility model,

Fig. 2 is the right view of embodiment Fig. 1 of the utility model

Among the figure: 1, base 1a, jack 1b, gusset 2, flap 2a, jack 2b, threaded block 3, plug 4, spring clip 4a, resilient clip opening 5, long spiro nail

In the embodiment of Fig. 1-2:

Present embodiment is the three-plug connector that is used to connect two three-way power supply appliance plugs.Base 1 is that plastic casing, its end face of an insulation is oblong openings, the bottom surface is that rectangle sealing surface end face is bigger than bed-plate dimension, and there is the countersunk head screw in bottom center, one vertical rectangular jack 1a is arranged in the longitudinal centre line top at countersunk head screw place, and following symmetrical longitudinal centre line two be arranged in " eight " font two rectangular jack 1a that intersect 60 °, and three rectangular jacks are measure-alike.Be connected with gusset 1b in the base 1, isolate three rectangular jack 1a.

Flap 2 also is the plastic casing of an insulation, its bottom surface is an oblong openings, match with the end face of base 1, and the centre of end face is the plane that is parallel to base 1 bottom surface, both sides are to face outer inclined-plane symmetrically, all be provided with the rectangular jack 2a of identical size with the bottom surface of base 1 and layout on two inclined-planes, wherein on the inclined-plane of the flap 2 on one side of jack 1a on base 1 longitudinal centre line, rectangular jack 2a on the longitudinal centre line up, and on another inclined-plane, the rectangular jack 2a of longitudinal centre line also up.Be provided with threaded block 2b in the mid-plane to inner process.

Plug 3 is three conductive metal sheets in rectangle cross section, and an end passes and exposes outside the rectangular jack 1a of base 1 bottom surface, and the other end is in base 1, with the fixedly connected corresponding spring clip 4 of conducting metal rivet.

Spring clip 4 is elastic conduction sheet metals of conduction, and left and right two ends are to the left and right resilient clip opening 4a of upper process, and the angle of inclination, top of its folder mouthful 4a is consistent with the inclination of flap 2 respective ramp, and contacts below corresponding jack 2a.

Long spiro nail 5 passes the countersunk head screw of base 1 bottom surface, in the screw thread of the threaded block 2b of screw-in flap 2, connects base 1 and flap 2, and the inboard, two inclined-planes of flap 2 is contacted with the spring clip mouth 4a top of spring clip mouth 4.

The electrical connection principle is as follows:

Three pin plug 3 inserts in the corresponding jack of three-plug connector on the wall, the plug of two three-way power supply electrical equipment, insert the jack 2a on flap 2 inclined-planes respectively, put in the spring clip 4 corresponding spring clip mouth 4a clamped at last, because spring clip 4, plug 3 all are conductors, be again directly to be fixed together, therefore, three-way power supply electrical equipment and wall three-plug connector are connected.

The utility model is compared with terminal block (band plug and electric wire), and cost is lower, takes up an area of little, attractive in appearance, easy to use and safe and reliable, in addition, the both sides of flap 2 end faces tilt laterally, further reduce the size of this three-phase socket, and moulding is also more attractive in appearance.
