Description

Wall extension socket

Technical field

The utility model belongs to conductive connecting device, relates in particular to a kind of socket.

Background technology

Wall socket refers to and is arranged on the appliance socket using on wall, is generally divided into two kinds of three holes and diplopores, existing wall socket because of for convenience of, safety, not taking up space is subject to general application.For part outdated building, it is less that wall socket designed number at that time, can not meet the demand of current multiple electrical appliance electricity consumption simultaneously, re-starts transformation and not only bother, and cost is high, and use inconvenient; In addition resident family's private is drawn and is disorderly connect power line and install socket wiring board additional, usually causes physical electrical shock fire protection and electrical fire accident, brings major safety risks to personal safety as well as the property safety.

Utility model content

The defect existing in order to overcome prior art, the purpose of this utility model is to provide a kind of wall extension socket, and solution conventional wall socket number is less, the problem of transformation trouble, and use is flexibly, conveniently; Reduce private and draw power line and install socket wiring board additional, eliminate safe hidden trouble.

Wall extension socket, comprise five hole wall sockets, front panel, circuit board and rear board, on front panel described in being characterized in, at least establish combination hub and a pair of screwed hole that two groups of tripods are combined with bipod, combination hub can use different plugs according to demand, improves the utilance of socket; On described circuit board, at least establish two groups of inserted sheets that formed by copper sheet, inserted sheet is connected in series by wire by live wire, zero line, ground wire polarity respectively, inserted sheet is corresponding with the combination hub of front panel successively, at least establishes two through holes on circuit board, and circuit board is fixed on front panel by screw; On described rear board, establish a two-pin plug and a three-pin plug, the end of plug is the corresponding connection of inserted sheet with circuit board by copper conductor, the through hole of screwed hole, circuit board of establishing a pair of through hole and front panel on rear board is corresponding, front panel, circuit board and rear board are fixedly connected with by screw, two plugs can be fitted with five hole wall sockets, and plug-in mounting is firm.

The utility model further improves, and establishes mains switch and power supply indicator on described front panel, and with the electrical connection of circuit board plug, mains switch is push-button switch, conveniently starts, closes socket general supply.

The utility model further improves, on described wall socket, at least establish two screws, what front panel, rear board were corresponding with circuit board establishes location hole, fixed by dog screw, in the situation that socket uses for a long time and do not need often plug, whole extension socket and original wall socket are fixed together, improve fastness.

The utility model further improves, the top pin of the tripod jack of described combination hub is parallel be placed in and bipod jack between, two footing and the bipod jack of tripod jack are set up in parallel, and save panel space, improve the utilance of socket.

Compared with prior art, advantage is novel, and structure letter gathers, rationally; The utility model back side adopts bipod and three-pin socket, inserts after wall socket, and structure is more stable, and laminating degree is high, aesthetic in appearance, saves space; Increase dog screw, the in the situation that of using for a long time at extension socket, frequently do not plug, can use dog screw that whole extension socket and wall socket are fixed, increase the fastness of structure, use safer; Adopt front panel, circuit board, the design of rear board three-decker, convenient for production, it is convenient to install.

Brief description of the drawings

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Fig. 1 is wall extension socket stereogram;

Fig. 2 is end view of the present utility model;

Fig. 3 is the utility model intermediate circuit plate structure schematic diagram;
