Description

The multipurpose safety electric power connecting device

The utility model relates to a kind of bipolar pair of parts circuit jockey with the supplementary protection grounding component in the electricity field, further is meant a kind of multipurpose safety electric power connecting device that equipment or structure get on that is fixed to.

Be unable to do without in modern people's live and work, want electricity consumption just often will dial plug-in source joint, therefore many electric equipments and utensil all have been equipped with an attaching plug with two cores or three core conducting plugs (generally being latch or inserted sheet), and the quantity of the conducting plug of these attaching plugs, shape, put the position, apart from size design multiple version arranged, therefore just require to have the corresponding supply socket use that matches.The so-called multipurpose socket that existing a kind of user of enjoying welcomes on the market, it can satisfy the grafting needs of the attaching plug of existing various versions basically, yet blemish in an otherwise perfect thing is, now all can with the attaching plug of its matched use, be conduction plug connector exposed conveying appliance invariably, staff is easy to touch, and therefore the metal conducting plug that exposes causes electric shock accidents easily in the plug process, makes the user to watch out for by SC.For the purpose of safety utilization of electric power, occurred in recent years on the market a kind of have the insulation that conducting plug is surrounded enclose frame safety plug and with the safety socket of the matched use of this safety plug, it is that safety does not have anxiety that the user uses, but the unsatisfactory and inconvenient part of this safety plug socket that must supportingly could use is, the attaching plug of other multiple version can not with the matched use of its safety socket.In view of above-mentioned, therefore many users expect, if a kind of novel power supply plug assembly production appearance that collects the advantage such as the one of above-mentioned multipurpose socket and complete safety plug socket can be arranged, then can satisfy the convenient needs of pegging graft of attaching plug of various versions, solve the problem of safety utilization of electric power again.

The purpose of this utility model, on the basis of existing multipurpose socket and complete safety plug socket structure, improved, provide a kind of and can satisfy the grafting needs of the attaching plug of various versions, can guarantee the multipurpose safety electric power connecting device of safety utilization of electric power again.

Solution of the present utility model is as follows: it still has an independently safety socket, safety socket has the insulated receptacle platform and encloses the frame holder with molded being looped around of linking into an integrated entity in insulated receptacle platform bottom around the insulated receptacle platform, enclose between frame holder and the insulated receptacle platform and leave the ring-type groove, offer three vertical conducting plug spliced eyes on the insulated receptacle platform, in three conducting plug spliced eyes conductive holder is housed all, three conductive holder bottoms all are connected with stretches out insulated receptacle platform and the power supply wiring sheet that encloses outside the frame holder bottom face; Have a multipurpose socket base and be installed on the multipurpose socket base and the removable socket cover that takes away, offer three groups of abnormity jacks that can insert on the socket cover for the plug of multiple version, three isolation region internal fixation of the multipurpose socket base inside of three groups of abnormity jack belows are equiped with three groups of abnormity conductive holders, the utility model feature part structurally is, below the multipurpose socket base, have and the bottom surface of multipurpose socket base fuses can adaptive insertion safety socket upper enclosure frame holder and the insulated receptacle platform between safety plug insulation in the annular ditch groove enclose frame, this insulation is enclosed and is equiped with the conducting plug among the conductive holder within three three conducting plug spliced eyes can distinguishing adaptive insertion insulated receptacle platform in the frame, the bottom surface of multipurpose socket base is passed and is fixed on the top of these three conducting plugs respectively, their top then respectively with the multipurpose socket base in three groups of abnormity conductive holder bottoms conduct electricity contact mutually, and all a little higher than safety plug in their bottom insulate and encloses the frame bottom face and be hidden in this insulation and enclose frame inside.

The utility model with said structure is when installing and using; its safety socket is fixed on power patch panel or other member; and on the power supply wiring sheet of safety socket, insert single phase poaer supply line and protective earthing line, so just power supply and protective earthing are incorporated in the safety socket.When not needing electricity consumption, safety plug that fuses and multipurpose socket and independently suitable between the safety socket to be separated into.When needs grafting electricity consumption, in the multipurpose socket with the first insertion of the attaching plug of power consumption equipment or electrical equipment siamese part of the present utility model, and then in the safety plug insertion safety socket with siamese part.When electricity consumption finishes when pulling the plug out of the socket, then earlier extract safety plug from safety socket, just pull out the plug of power consumption equipment or utensil then from multipurpose socket, precedence can not be put upside down, but generally is advisable not pull out the power consumption equipment on the multipurpose socket or the plug of utensil.If the attaching plug of power consumption equipment or utensil be can with the utility model matched safety plug of safety socket independently, then this safety plug directly can be inserted safety socket of the present utility model, and needn't (also can not) through the intermediate conversion of multipurpose socket.

Therefore the utility model device is any electric equipment except that tape insulation encloses the safety plug of frame or the attaching plug of utensil because its multipurpose socket can be pegged graft, and therefore has extensive applicability, greatly facilitates the user.Meanwhile, again because of in the process of plug safety plug, the conducting plug that powers on of band is enclosed frame by the insulation of safety plug to be kept off and covering, and staff may not touch, and therefore has fail safe, has stopped because the smooth dew of conducting plug and issuable electric shock accidents.
