A gear rack is arranged in each of the wiring grooves, the bottom end of the conductive sheet (41) is provided with a tip end (411), and an n-shaped conducting sheet (2) is provided with a tip end (21) to make the utility model have the advantages of easy assembly and firm structure.

Description

Power supply plug

The utility model belongs to the illuminating attaching plug device of a kind of electrician.

Normally used plug, the line end of its two electric wire is directly to weld with two conducting strips, or with bolt line end is exposed copper cash and lock, yet its assembling of the mode of welding is trouble comparatively, and easy contaminated air, health risk during welding, assemble the shortcoming that then has line end to come off easily in the screw lock mode again, cause loose contact easily or open circuit.

The purpose of this utility model is to propose a kind of attaching plug of mainly being made up of a pedestal, two conducting strips, " Jiong " shape conducting strip, key and shell, its line end easy to assembly and electric wire can not cause short circuit, thereby has solved the existing in prior technology problem.

The technical scheme that the utility model adopted is that it is mainly by a pedestal, two conducting strips, one " Jiong " shape conducting strip, one key and shell are formed, it is respectively to establish a tip on the bottom of a conducting strip and a Jiong shape conducting strip, and just make this two tip be arranged in two wiring ducts, therefore two electric wires are directly to press fit in the wiring duct when assembling, this two tip punctures into electric wire and the copper cash in inside contacts and can switch on, respectively be provided with a tooth bar in this two wiring duct simultaneously, use the frictional force that when electric wire is inserted in the wiring duct, can increase between electric wire and the wiring duct, establish a cylinder at pedestal near the bottom again, make electric wire when assembling, can twine this cylinder, so, then electric wire when careless pulling more difficult drop-off can reach more firm effect in conducting strip.

That the utility model characteristics are is simple in structure, assembling easily, two electric wires when assembling directly to press fit in the wiring duct, and puncture into electric wire by having two most advanced and sophisticated conducting strips respectively, and contact and can switch on the copper cash of inside, and in two wiring ducts, be provided with a tooth bar, make it increase frictional force between electric wire and the wiring duct, thereby make the fixing of two electric wires can be very firm, the electric wire line end after can not coming off and assemble can not cause short circuit.

Fig. 1 is a schematic appearance of the present utility model.

Fig. 2 is STRUCTURE DECOMPOSITION figure of the present utility model.

Fig. 3 is the structural representation after the utility model combination.

Further specify a preferred embodiment of the present utility model in conjunction with above-mentioned each accompanying drawing now.The utility model mainly is made up of a pedestal (1), two conducting strips (41), (42), one " Jiong " shape conducting strip (2), a key (6) and a shell (7).Wherein, central authorities at pedestal offer a fuse storage tank (11), can supply ccontaining this fuse (3), the left and right both sides of pedestal (1) respectively offer a wiring duct (12), (13), again a left and right slot (14), (15) of respectively offering in the top of pedestal (1).Two conducting strips (41), (42) are arranged in the slot (14), (15) of pedestal (1)." Jiong " shape conducting strip (2), be arranged at the bottom of fuse storage tank (11).Shell (7) is coated on the outside of pedestal (1).One key (6) is inserted between pedestal (1) and the shell (7).

Respectively be provided with just like stair-stepping tooth bar (121), (131) in two wiring ducts (12) of pedestal (1), (13), and in offering between slot (14) and the wiring duct (12) every (16), every (17), can reach insulation effect in also being provided with between slot (15) and the wiring duct (13).Between slot (14) and wiring duct (12), be provided with a garden post groove (18) again, one line end (51) of supply lines (5) inserts, also be provided with a garden post groove (19) between slot (15) and the wiring duct (13), one line end (52) of supply lines inserts, pedestal (1) is installed with a cylinder (10) near the bottom, and shell (7) is installed with elongate body (71), (72) respectively corresponding to wiring duct (12), (13) position, and a conducting strip (41) bottom is provided with tip (411) and " Jiong " shape conducting strip (2) is provided with tip (21).

When assembling, two conducting strips (41), (42) are installed in respectively in slot (14), (15), and " Jiong " shape conducting strip (2) is put the bottom that is embedded in fuse storage tank (11).Insert fuse (3) again, top (31) the contact conducting strip (42) of fuse this moment (3), bottom (32) contact " Jiong " shape conducting strip (2), again with line end (51), (52) insert Cylinder (18) respectively, (19), tear open and just insert wiring duct (12) after curved, (13) in, this cylinder (10) is twined in the back, the whole central authorities that insert shell (7) of last semi-finished product as shown in Figure 3, before this, elongate body (71), (72) will execute a pressure to electric wire (5), electric wire is punctured by this tip (411) and (21) and should contact inner copper wire in the tip, and electric wire will be close to this tooth bar (121), (131) on, therefore very firm, insert key (6) at last again and promptly belongs to assembling and finish.
