Abstract

This utility model discloses a large power assembly plug, comprising a plug housing which includes the upper cover and the lower cover. Groove chambers are positioned in the lower cover and bolts are respectively arranged within the groove chambers. Sleeve bolts are arranged on the rear ends of the bolts for connecting to the power supply wire. The copper sleeve which has the screw teeth is embedded in the sleeve bolt. The sleeve bolt is provided with a horizontal shark-tooth terminal hole. The power supply wireis inserted into the shark-teeth terminal hole through the shark-tooth terminal. The assembly plug can be adapted to various appliances with big power by the improved bolts and improves the safety and provides convenience for usage. The internal bolts or other internal parts of the assembly plug can be replaced, so that the large power assembly plug satisfies safety requirements and is easy to produce.

Description

A kind of High Power Assembling plug

Technical field

The utility model relates to appliance socket field, particularly a kind of High Power Assembling plug.

Background technology

Part household electrical appliance can need to use low power detachable plug and non-dismountable formula plug, for example, when Switzerland's plug is general, use the plug of 10A.When using, current capacity is excessive, can burn out household electrical appliance or plug, and household electrical appliance are produced to sense of insecurity.Therefore being necessary needs powerful plug with meeting the market requirement.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of safer High Power Assembling plug.

The utility model solves the technical scheme that its technical problem adopts:

A kind of High Power Assembling plug, comprise plug casing, described plug casing comprises upper cover and lower cover, described lower cover has vallecular cavity, described vallecular cavity is built-in with respectively latch, and the rear end of wherein said latch is provided with the sleeve column for being connected with power line, and this sleeve column is embedded in the copper sheathing with screw thread, on described sleeve column, have the shark tooth terminal hole of horizontal direction, described power line inserts shark tooth terminal hole by shark increment.

In order to improve the soundness of installation, the rear end of described latch is provided with L-type block structure, and described sleeve column is arranged on L-type block structure.

Loosening for fear of power line, the rear inside of described plug casing is provided with for pushing down clamp and the tension disc of power line, and the both sides of described clamp and tension disc are respectively arranged with screw mounting panel, and the inner side of wherein said clamp is provided with reinforcement.

Anti-inserted in order to prevent plug, the outer surface of described plug casing has the straight groove of Anti-dislocation of vertical direction.

The beneficial effects of the utility model are: this assembly type plug, by the latch of improvement, can adapt to high-power electric appliance, during use, household electrical appliance are had to fail safe, and plug is easy to use, easily changes the inner parts such as latch, not only meet safety requirements but also easily produce.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Fig. 1 is stereogram of the present utility model;

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

Fig. 3 is the stereogram of latch part in the utility model.

embodiment

With reference to Fig. 1, Fig. 2, a kind of High Power Assembling plug, comprises plug casing 1, and described plug casing 1 comprises upper cover 2 and lower cover 3, upper cover 2 for lower cover 3 assembling that fits like a glove, can boss rank 10 be set at the outer edge that connects of upper cover 2.The outer surface of described plug casing 1 has the straight groove 11 of Anti-dislocation of vertical direction, prevents that plug is anti-inserted.Plug casing 1 is outer to be also provided with for the fixing outer surface screw counterbore 12 of wire rod.Described lower cover 3 has vallecular cavity 31, and described vallecular cavity 31 is built-in with respectively latch 4, and the front end of latch 4 stretches out plug casing 1 as the pin of plug.With reference to Fig. 3, the rear end of described latch 4 is provided with the sleeve column 6 for being connected with power line 5, this sleeve column 6 is embedded in the copper sheathing 61 with screw thread, on described sleeve column 6, have the shark tooth terminal hole 62 of horizontal direction, described power line 5 inserts shark tooth terminal hole 62 by shark increment 51, can greatly improve between power line 5 and latch 4 and connect fastening degree.In order to improve the soundness of installation, the rear end of described latch 4 is provided with L-type block structure 41, described sleeve column 6 is arranged on L-type block structure 41, L-type block structure 41 is for high-power plug, except improving the soundness being connected between latch 4 and electric wire, L-type block structure 41 itself also reduces latch 4 and occurs loosening possibility.

Described latch 4 comprises L, N utmost point latch and E utmost point latch, and wherein L, N utmost point latch adopt brass material, plating zinc on surface; Described E utmost point latch adopts brass material, and surface does not need zinc-plated.For the special plug of segment polarity, the E utmost point and the L utmost point are in outer end, and the N utmost point is in centre.

The rear inside of described plug casing 1 is provided with for pushing down clamp 55 and the tension disc 52 of power line 5, the both sides of described clamp 55 and tension disc 52 are respectively arranged with screw mounting panel 53, the inner side of wherein said clamp 55 is provided with reinforcement 54, and clamp 55 and tension disc 52 coordinates and clamp power lines 5 and prevent that it from looseningly causing short circuit or opening circuit.

Actual concrete manufacturing step is as follows:

1. the sizing material ABS material that needs the plug casing 1 of injecting products, toast 2 hours, then this sizing material is poured into the barrel the inside of injection molding machine;

2. plastic mould is packed into above injection molding machine, regulate temperature, pressure, the parameter of the equipment such as time;

3. start dynamic model and cover half matched moulds, through injection ABS sizing material, flow in mold cavity, then solidify through pressurize, parting then, the goods process cooling forming in mould, finally takes out goods upper cover 2 and lower cover 3.Because injection mold is mandarin duck mould, once-forming is upper cover 2 and lower cover 3.

4. wire rod front end, through peeling opening, is beaten shark increment 51 after opening;

5. penetrate after the shark tooth terminal hole 62 of latch 4, latch 4 is respectively charged into successively to vallecular cavity 31 the insides of the vallecular cavity 31 of the L utmost point latch of lower cover 3, the vallecular cavity 31 of N utmost point latch and E utmost point latch again;

6. with clamp 55 and tension disc 52, be fixed on the screw column hole of lower cover 3, the upper cover 2 of plug casing 1 is connected with lower cover 3 use screw lockings again.

According to above-mentioned principle, the utility model can also carry out suitable change and modification to above-mentioned execution mode.Therefore, the utility model is not limited to embodiment disclosed and described above, to modifications and changes more of the present utility model, also should fall in the protection range of claim of the present utility model.

Through facts have proved, the utility model, by the latch of improvement, has good electric conductivity, and load current is large, and the distribution of plug can reach 2.5mm ²large wire rod; In addition this plug assembling simple operations convenience, and plug profile and socket have error-disable function, avoid the anti-inserted accident that causes of plug.
