Abstract

The utility model discloses a three-phase power supply plug, comprising inserting posts, a handle, a conducting wire connecting part and a perforating wire. The utility model is characterized in that the fixing end of each of the inserting posts is respectively connected with a supporting frame, and the outer part of a rod of the supporting frame is sheathed with a lock sleeve. A compression spring is arranged between the rod and the hole wall on the outer side of the lock sleeve, and a radial through hole is generated on the post surface of the handle corresponding to the end surface of the outer side of the lock sleeve. The inner part of the through hole is provided with a button, when the lock sleeve is internally moved to a limit position, a hole cavity of the lock sleeve on the inner side of the rod is just corresponding to each perforating hole arranged on the end surface of the handle. Compared with the prior art, the utility model has the advantage of quicker and more convenient disconnection and connection of the conducting wire.

Description

A kind of three phase mains plug

The utility model relates to a kind of attaching plug, exactly is a kind of three phase mains plug.

Existing three phase mains plug mainly is made up of inserting column, handle, inserting column and connecting wire relay part, through wires hole.Wherein, handle is made of the box body that profile is cylindrical shape, and inserting column and connecting wire relay part are formed by nut and adapted packing ring thereof, and both are respectively applied for being fixedly connected between inserting column stiff end and handle end cap and inserting column and the lead; Wire hole is made of a through hole that is arranged on the handle cylinder.In the use, when people need take apart or during the joining power lead, will pass through following process: open handle end cap earlier, take apart or the secure wires coupling components again, refill the upper handle end cap at last.This shows that it is convenient, fast inadequately that this attaching plug disconnects the operation of lead.

The purpose of this utility model is to provide a kind of operation that can make it tear, connect lead open more quick and easy three phase mains plug for people.

The purpose of this utility model is to realize like this, it comprises inserting leans on, handle, the connecting wire relay part, perforation line, be characterized in connecting respectively on each inserting column stiff end a support and make it to form the body of rod parallel with inserting column, this body of rod is nested with outward can be along the back and forth directed ring body shape lock tube that moves of handle radial direction, between the hole wall of the outside of the body of rod and lock tube, the compression spring is set, on the handle cylinder relative, make radial direction through hole with lock tube outside endface position, be slidingly installed in the through hole and have the outer button that moves the backstop that comes off, when moving to extreme position in the lock tube, the lock tube vestibule that is positioned at described body of rod inboard is just relative with each the through wires hole position that is arranged on respect on the inserting column one side handle end face, described support and inserting column electrically connect, described lock tube contacts described support with the button insulation, lock tube, spring, button is formed described connecting wire relay part.

Be provided with between the medial surface of above-mentioned handle two ends can make each described connecting wire relay part and and its joining lead wire terminal between the dividing plate of mutually insulated.

On the handle cylinder circumference between described each button axial notch is being set, and in the groove ends of a relative side with described inserting column projection is being set, this groove and projection constitute plug and scratch hand.

After the utility model is realized, the user needs only a side pressure knob down in handle cavity, in the lock tube vestibule of support body of rod inboard, insert or extract lead by through wires hole again, and then release button, can realize connecting or take apart between the utility model and the lead, thus the utility model is compared with prior art had can make it and lead between disconnect the more quick and easy advantage of operation.

Below in conjunction with accompanying drawing embodiment of the present utility model is done explanation in further detail.

Fig. 1 is a front view of the present utility model.

Fig. 2 is the side direction view of Fig. 1.

Fig. 3 is that the B-B of Fig. 1 is to part sectioned view.

As seen from the figure, the utility model comprises that handle of the prior art, inserting column 9,12, inserting column coupling components are nut 10, connecting wire relay part, through wires hole.Wherein handle is made up of nut 7, end cap 16, joint bolt 6 in body 2 and the solid heart hole therein of notes respectively.Design feature of the present utility model is that the connecting wire relay part is made up of button 1, compression spring 3, support 4, lock tube 5 respectively.Wherein, support is a member that is connected on the inserting column stiff end and can forms parallel its axis direction body of rod, and described inserting column stiff end is meant and inserts handle cavity one end end interior and that be fixedly connected by nut 10 and its end cap 16.In the present embodiment, support 4 is square members that form with the lath system of simmering, and right-angle side of this member constitutes its stiff end, and another right-angle side forms the described body of rod.Support is fixedly linked on the inserting column stiff end by the connection holes of making on its stiff end, the coupling nut 11 of adapted; Lock tube 5 is rectangle ring body shape members, its endoporus Width two sides respectively with the two sides sliding contact of the support body of rod, its length direction then is provided with along the handle radial direction, thereby lock tube can be moved along the handle radial direction is back and forth directed under external force, and this lock tube is used for connecting conducting wire; Hole wall was promptly away between handle center's one side opening wall outside compression spring 3 was installed in the support body of rod and lock tube, and this spring is used for the lock tube return; Button 1 is the axis body shape member that one one end is shaped on the shaft shoulder, it by its axis body sliding plug be positioned on the handle side wall and with the relative radial direction through hole of lock tube outside endface position, also make its shaft shoulder be positioned at handle cavity simultaneously, this shaft shoulder constitutes the outer backstop that comes off of moving of button, and this button is used for pushing lock tube; Through wires hole 8 is arranged on the relative side handle end face with inserting column, and the position, hole is definite like this: when moving to extreme position in the lock tube, each through wires hole is relative with the lock tube vestibule position of each support body of rod inboard respectively.

Above-mentioned support adopts metal material to make, and electrically connects with inserting column, and button adopts insulating material to make, thus make it and the metal lock tube between keep insulation.

Can remain mutually insulated in the utility model use for making between each lead wire terminal and the coupling components thereof, so that improve its usage safety performance, the utility model also is provided with dividing plate 15 between the medial surface of the two ends of handle.This dividing plate is not set certainly, and the utility model also can use.

The utility model is extracted on the socket of its adapted for convenience, is making axial notch 13 on the handle cylinder between each button, and in each groove ends of a relative side with described inserting column projection 14 is set, and this projection and groove constitute plug and scratch hand.

Above-mentioned execution mode of the present utility model is not unique, for example: first, support can be made of the metal cartridge that an end has a screw, this cylinder links by screw and inserting column stiff end double-screw bolt, simultaneously, for being set, spring needs on the cylinder outer surface, to make a flat notch that matches with spring the inner.In addition, support also can have other version, is not repeated; The second, lock tube can be that the ring body of long kidney-shaped hole constitutes by endoporus also; The 3rd, lock tube and button all adopt insulating material to make or lock tube adopts insulating material to make, and button is when adopting metal material to make, and the utility model all can use.
