Abstract

The utility model belongs to the technical field of low-voltage electrical apparatus products, particularly a combined electrical socket which can be increased or decreased of the quantity of the socket and can be replaced of the jack. The utility model is characterized in that the socket is composed of a master socket plate and more than one auxiliary socket plates, and the master socket plate and the auxiliary socket plates are combined with the master socket. The side of the master socket plate is provided with a concave groove and a convex column which are exactly matched with the convex column and the concave groove (which are arranged on the side of the auxiliary socket plates). The utility model has the remarkable effect that the master socket plate and the auxiliary socket plates can be clamped and connected by the selected interval plates, so that the quantity of the socket and the form of the jack can be increased and decreased arbitrarily. The utility model has the advantages of universality, flexibility and wide use.

Description

The combined electrical supply socket

The utility model belongs to the low-pressure electronic equipment product field, particularly a kind ofly can increase or reduce the socket number at any time, changes the combined electrical socket of jack form.

The present low-voltage electrical apparatus that uses, all being one part receptacles, promptly all is on the socket of a fixed size, and some groups of jacks are installed, comprising three flatly inserting of being fit to various current strength, three circles are inserted, two flatly insert, two circles are inserted some groups, or some groups of combining of flat round hole.In case behind selected certain the piece electric mortiser plate of user, want to change the jack form, it is just very difficult perhaps to expand some groups of jacks, even increase the transition plug, also only be limited expansion, and volume is big, burdensome, use extremely inconvenient, more cannot remove some groups of idle jacks, reach reduced volume, economical and practical purpose because of operating position changes.

The utility model its objective is the electrical socket of a kind of fabricated structure of design at the shortcoming of existing socket, can be according to actual needs, and combination anywhere or anytime increases or reduces the form or the quantity of jack.

The purpose of this utility model is to realize like this, by base, the socket that back shroud and front shroud constitute, be provided with the socket piece in the base, on cover and have the jack that matches with plug, the slotting pawl of each of jack place is communicated with power line by corresponding lead, it is characterized in that socket is to constitute by the baseplug plate with the combined socket of paying more than of baseplug plate, baseplug plate side is provided with groove and just in time set with paying socket side projection and the groove of projection matches, main, the lateral grooves of paying socket is equipped with an elastic conduction post that is connected with three slotting pawls respectively by lead with projection centre and center, side, make the master, when paying the socket groove and matching with projection, elastic conduction post contact can keep in touch conducting, and makes the master thus, the slotting pawl of paying socket passes through lead, elastic conduction post contact is pressed live wire and live wire, ground wire and ground wire, zero line and zero line mutual conduction.

Knockdown like this electrical socket, can be by a main plate, pay socket and side cover plate formation for some, baseplug plate portion or each side all can be provided with groove and projection, the front can be provided with some groups of jacks, and be connected to power line, same pair of socket part or each side all can be provided with projection and groove, the front can be provided with one group of jack, the projection groove of paying socket could pass through the power line energized of baseplug plate when having only the groove projection with the baseplug plate to be interlocked, plate divides A, two kinds of models of B, the equal connecting to neutral line of the elastic conduction post on the projection of A type side, conductive pole on the groove line of all starting to exchange fire, the difference of Type B plate and A type, when only being internal receptacle connection lead, live wire and zero line exchange, projection leads to live wire, and groove leads to zero line.When inserted block expands combination, must A, Type B docks at interval, to guarantee that all expand the three-phase jack on the plate, all by live wire and live wire, ground wire and ground wire, zero line and zero line mutual conduction, in addition, for safety side cover plate can be set, side cover plate can cover exposed groove and the projection in electrical socket side after the combination.

Therefore, remarkable result of the present utility model is: adopt such electrical socket, can pay plate by selectable interval clamping A, Type B, increase or reduce the single-socket number arbitrarily and change the single-socket form, existing versatility, flexibility is arranged again, the plug demand that constantly changes of coupling ideally, simultaneously according to the plate side can both the clamping conducting characteristics, be combined into rectangle, square etc., to adapt to various installation position, both economical and practical, easy to use again.

Concrete structure of the present utility model is realized by the following examples and accompanying drawing;

Fig. 1 is an installation diagram of paying plate (A type).

Fig. 2 is the structural representation of main plate.

Fig. 3 is that installation diagram is looked on a left side of paying plate (A type).

Fig. 4 is the schematic diagram of the utility model embodiment.

Below in conjunction with accompanying drawing 1-4, further describe the utility model embodiment:

Referring to Fig. 1, elastic conduction post 3,5,7 is equipped with in base housing 1 every side, and it is on the sidewall and groined type muscle by stage clip 8 and snap ring 5 stuck-at-s, the convex conductive pole 3 of every side is by lead 9, A type connecting to neutral line, the Type B line of starting to exchange fire, matrix conductive pole 7, by lead 9, the A type line of starting to exchange fire, Type B connecting to neutral line, the conductive pole 5 in the middle of every side, the A type is a female contact, Type B is the convex contact, by lead 9 equal earth connections, when A, Type B are docked at interval, can not make a mistake.Cover back shroud 13, just become a complete plate.

Referring to Fig. 3, wherein the slotting pawl 12 of plastic socket block 11 and elasticity is combined into the plastic socket block assembly 4 among Fig. 1, changes multi-form front shroud 10 and corresponding plastic socket block 11, can generate the plate that is fit to multi-form plug.Select the plate of paying of various models for use, A, Type B clamping at interval connect main plate (referring to Fig. 2) at last, can be combined into the various model plugs of coupling, number is come by the arbitrarily fixed supply socket of user, for safety, and when the combination exposed side of rearward recess projection that finishes all covers with side cover plate 2.

Fig. 4 is an embodiment schematic diagram of the present utility model, pay plate 2 and Type B pays plate 3 clampings by the A type, connect main plate 1 at last, be combined into a block power supply socket, this socket not only has the function of conventional socket, and in 1,2,3 sides that do not snap fit onto, all remains with the leeway of expansion board plugboard, to wait when needed, the supply socket that combination makes new advances comes.
