By means of the junction box circuit connector, electricity can be connected in and led out reliably and conveniently, the inner space of an electrical junction box inside a wall is less occupied, a wire head does not need to be squeezed rigidly and manually, and the junction box, a socket, a light switch and the like can be conveniently installed on the wall.
Description
Technical field
The utility model relates to a kind of terminal box line connector.
Background technology
At present, in the known modern architecture, for electricity consumption convenience, attractive in appearance, the distribution socket of installing on the indoor wall, light switch and electric junction box mostly adopt concealed installation method within the walls, this installation method uses a less hollow plastics box, according to the wiring needs, many appliances power source lines and the control line electric wire of installing within the walls can be electrically connected mutually.If what connect is supply socket or light switch, after also needing again to draw separately on the wire connecting with lead, be connected on the joint of supply socket or light switch.These electrical connectors adopt " twisted shape " articulated manner to connect usually.
Single core aluminium or copper plastic wire are used in wiring usually within the walls, volume was bigger after these leads were hinged to one, hardness is also higher, be not easy bending, can take the more useful space in the concealed installation terminal box, fixedly when distribution socket or light switch panel, installation personnel must flatten by force, the hinged wire head of multiply of crooked terminal box inside, fixedly distribution socket or light switch panel.And this operating process meeting causes articulated manner hard lead together to flatten, occur when crooked broken end, hinged situation such as loosening by force in external force, cause the interior circuit of concealed installation box after operation a period of time, blank area is because of loose contact, the sparking in addition blow union line, bring hidden danger to safety utilization of electric power.Indoor built-in line fault major part all appears within the walls in the terminal box, and main cause just is this.
The utility model content
The purpose of this utility model provides a kind of terminal box line connector, can realize electricly reliably inserting easily and drawing.
A kind of terminal box line connector, its special feature is: comprise fastening nut and the fastening bolt that is mated, wherein the inwall at fastening nut is provided with screw thread, and on the other inwall of this screw thread, also be provided with an inner conical face, and fastening bolt is hollow tubular, on the outer wall of this fastening bolt, also be provided with screw thread, and the outer wall other at this screw thread is provided with a male-tapered face, on this male-tapered face, have at least 2 grooves that extend to the fastening bolt end vertically, thereby the male-tapered face portion of fastening bolt is divided at least 2 lobes.
Thereby wherein have 3 or 4 grooves outside on the taper surface vertically the male-tapered face portion is divided into 3 lobes or 4 lobes.
Wherein also comprise the installation base plate, have at least 2 installing holes at this installation base plate, on each installing hole, all be installed with a fastening bolt.
Wherein be hinged with a plastic insulation outer cover at the installation base plate.
The utility model provides a kind of terminal box line connector, can realize electricly reliably inserting easily and drawing, take the inner space of electrical junction box within the walls less, need not artificial rigid extruding wire head, conveniently terminal box, socket and light switch etc. on the installation wall.The utlity model has multi-thread head and enter and draw function respectively, be electrically connected simple and reliablely, volume is little.Can expanded application to the power distribution cabinet connecting terminal block, the insulated hull that construction only need be peeled off connector lug inserts wiring units straight, screw nut and get final product, damage wires is more not easy for installation than conventional screw cap punch down terminal, do not need bending wire to do the line nose, improved installation effectiveness.

Embodiment
As Fig. 1,2,3,4, shown in 5, the utility model is a kind of terminal box line connector, comprise fastening nut 2 and the fastening bolt 4 that is mated, wherein the inwall at fastening nut 2 is provided with screw thread, and on the other inwall of this screw thread, also be provided with an inner conical face 1, and fastening bolt 4 is hollow tubular, on the outer wall of this fastening bolt 4, also be provided with screw thread, and the outer wall other at this screw thread is provided with a male-tapered face 3, on this male-tapered face 3, have at least 2 grooves 5 that extend to fastening bolt 4 ends vertically, thereby male-tapered face 3 parts of fastening bolt 4 are divided at least 2 lobes.
Thereby wherein have 3 or 4 grooves 5 outside on the taper surface 3 vertically male-tapered face 3 parts are divided into 3 lobes or 4 lobes.As shown in Figure 6, also comprise base plate 7 is installed, have 6 installing holes at this installation base plate 7, on each installing hole, all be installed with a fastening bolt 4, on installation base plate 7, also be hinged with a plastic insulation outer cover 8 in addition.
Current-carrying part in the utility model can adopt conventional electric conducting materials such as copper or aluminium alloy.
Using method of the present utility model is:
After during use lead being peelled off insulation sheath, core 6 parts of lead are penetrated in the hollow fastening screw, make the male-tapered face 3 of the inner conical face 1 extruding fastening screw of fastening nut 2 by rotation, make male-tapered face 3 parts produce certain elastic deformation, thereby stable clamping core 6 is realized good being electrically connected.Terminal box line connector of the present utility model is when reality is used, can the lead on the wall is interior until the top by each fastening bolt 4 in the bottom insertion terminal box line connector according to phase sequence, screw fastening nut 2 with box spanner then, realize being electrically connected reliably.
