Abstract

The utility model relates to a fully enclosed safety socket connector, which is connected with a power supply. The utility model is composed of an insulating plug and an insulating socket, wherein, an insertion post which is arranged on the insulating plug is a double-layer hollow sleeve tube, the inner layer of the double-layer hollow sleeve tube is provided with a conductive tube, the outer layer of the double-layer hollow sleeve tube is provided with a protection tube, the outer layer is slightly longer than the inner layer, and human bodies can not be contacted with conductive parts. An insulating protection frame is arranged in an insertion hole of the insulating socket, a conductive bottom post is deeply hidden on the bottom of the socket, and human bodies can not be contacted with the conductive parts.

Description

The fully-enclosed safe connector

The utility model relates to a kind of safe insertion spare that connects power supply.

At present, no matter be three-phase or two-phase power supply, connector all has the partially conductive body to expose outside insulator, and unless you give your whole attention to it, just might get an electric shock meets accident.

The utility model is at above-mentioned drawback, with whole ingenious being sequestered in effectively in the insulator of all current-carrying parts, provide a kind of easy and simple to handle, patch firm, safe and reliable connector.

Technical solution of the present utility model:

A kind of safe insertion spare; it is characterized in that it is made up of blind plug and insulated receptacle two parts; its outward appearance is similar to the ordinary plug socket; the inserting column that different is on the blind plug is the double-layer hollow sleeve pipe; skin is an insulation protection tube; internal layer is a contact tube, and part is tightly wrapped up and protection tube slightly is longer than contact tube because current-carrying part is insulated, and human body can not directly touch current-carrying part.

Be provided with the insulation protection frame in the jack of insulated receptacle, the conduction foundation in the socket is sequestered in the socket bottom dearly, and human body also can not directly touch current-carrying part.

During work, hollow bushing is inserting along the jack on the socket, and passes through fender bracket, and is also that the complete shutoff of the jack on the socket is tight when tightly being socketed on the conduction foundation power connection, the more impossible current-carrying part that touches of human body.

Owing to set up defenses in depth, so use this utility model just not have the danger of electric shock.

Fig. 1 is blind plug, insulated receptacle section of structure

Fig. 2 is blind plug, insulated receptacle outward appearance end view

Fig. 3 is blind plug, insulated receptacle outward appearance vertical view

Fig. 4 is blind plug, insulated receptacle outward appearance upward view

As Fig. 1,2 the utility model blind plugs insulation protecting cover 1, insulation roof beam structure 2, insulation pillar 4 and conductive tube 3 are arranged partly, insulation pillar 4 is vertically connected on the same plane of insulation fine strain of millet frame 2, this junction, plane, circular hole with insulation pillar same inner diameter is arranged, so that the conductive tube 3 that the grafting external diameter equates with the circular hole internal diameter.Conductive tube 3 has screw thread towards fine strain of millet frame one end, can connect power line by bolt, insulating lid 1 can be fixed on the insulation roof beam structure 2 after by wire guide 10 extracting power supply cords, and the other end of conductive tube should be consistent with insulation pillar 4, leaves cross section as Fig. 3-4 and be

The open seam of shape is protected "+" font part on the frame 7 so that it passes through insulation in the insulation jack 5 smoothly, and coincideing with conductive pole 8 effectively is connected, and power safety is connected.Insulated receptacle partly has insulator foot 6, jack 5 and conduction foundation 8, insulator foot 6 have two to three with the corresponding vertical jack 5 of blind plug, the internal diameter of jack 5 is slightly larger than the external diameter of insulation pillar 4, all have an insulation that fuses with the bottom surface, hole to protect frame 7 in each jack, the Lower Half that frame 7 is protected in insulation is by two The square crossing of type thin slice is formed.The thickness of thin slice should be less than on conductive tube and the pillar thereof The thickness of font open seam, the first half that frame is protected in insulation is stood on the crosspoint that two thin slices are formed by a small column, and its external diameter should be slightly less than the internal diameter of conductive tube 3.

The external diameter of conduction foundation 8 should be consistent with the internal diameter of conductive tube 3, and the preformed hole by the base bottom during assembling inserts, and is connected and is fixed on the bottom of base 6 with power line with bolt.

Behind extracting power supply cord, cover base cover 10 usefulness punching bolts 13 base cover 10 is fixed on the base 6.

When the utility model uses, open the insulation protecting cover earlier, again an end has been connect the other end of the power line of deciding the use body, penetrate by the wire guide on the protecting cover 1 10, slough one little section insulating barrier on the end points, exposed part is wrapped on the bolt on conductive tube 3 tops respectively totally, tight a bolt then, again the protecting cover 1 that will insulate is fixed on the insulation roof beam structure 2, like this, blind plug has just installed, then, insulated receptacle is installed again, cut off the electricity supply earlier, extracting power supply cord, and slough one little section insulating barrier on the end points, exposed part on the power line end points is wrapped in respectively on the bolt of conduction foundation 8 totally, tights a bolt.After the seat pillar 8 that will conduct electricity was pushed into the precalculated position, wire guide 12 extracting power supply cords from the bottom 9 covered bottom 9, by punching bolt 13 bottom 9 were fixed on can combined floodgate on the base 6 energising again and used.As need insulated receptacle is fixed on the jobbie, need only uses fixing hole 11 bottom 9, pre-fixed, by punching bolt 13 base 6 and bottom 9 are connected and fixed again and get final product.

Claims

1, a kind of fully-enclosed safe connector is characterized in that it is made up of blind plug and insulated receptacle, and the inserting column on the blind plug is the double-layer hollow sleeve pipe, and internal layer is a contact tube, and skin is an insulation protection tube, and slightly is longer than internal layer, and human body can not touch current-carrying part; Be provided with the insulation protection frame in the jack of insulated receptacle, the conduction foundation is sequestered in the jack bottom dearly, and human body also can not touch current-carrying part;

During work, hollow bushing inserts along the jack on the socket, utilizing the advantage of special moulding, passes through fender bracket, and is also that jack is stifled tight when tightly being socketed on the conduction foundation energized, the more impossible current-carrying part that touches of human body.
