Description

The structure-improved of computer power plug internal frame

The utility model relates to a kind of mains connection in the distribution technique.

The interior shelf structure of general computer power plug, be to go up, lower cover makes up in the mode of folding pressing, for reaching smooth pressing, its lower cover inner region is divided into power supply terminal and puts the dividing plate in district and become parallel directly tabular, on, lower cover is after assembling, form a complete attaching plug its outside covering thermoplastic plastic, yet, owing to normally adopt folding mode, last, one side of lower cover is provided with the folding part of a projection, this folding part is caused the outer plastic cement be full of cracks of covering easily, and folding mode can't with on, lower cover is closely fixing, and the power supply terminal in leaving in is come off, and causes quite high percent defective; In addition, when making the mould of upper and lower cover, be to move back mould with the sliding formwork formula, not only speed is slow, and the cost height of mould, and this production method is out of season under the balance of Financial cost.

The purpose of this utility model is to propose a kind of structure-improved of the computer power plug internal frame of mainly being made up of loam cake and lower cover, be provided with corresponding engage rail and slot, corresponding connecting hole and barb between this loam cake and lower cover, combination is fixing with push-in type, this structure can not make the combination of upper and lower covers fall back, and the power supply terminal in being clamped in is come off, thereby solved the existing in prior technology problem.

Another purpose of the present utility model is to separate into three power supply terminals to put the dividing plate front end in district and be formed with outer angle of opening in lower cover, makes the outer plastic cement that covers be difficult for inflow, and it is unimpeded to keep the passage of conducting terminal.

After a purpose more of the present utility model is that the mould manufacturing of this loam cake and lower cover is finished, be about fast, to move back the mould mode, can reduce expenses, reduce cost.

The technical scheme that the utility model adopted is that it mainly is the mode be combined into that is pushed engaging by a upper cover body and a lower cover and power supply terminal with track, wherein, this loam cake is to be provided with cover and combination section, this cover is provided with three upright square holes, be respectively ground wire, live wire and the earth connection inserting hole of attaching plug, the downside of its centre is provided with a connecting hole, the both sides outer rim of this combination section is provided with the holding section of a suitable thickness, centre is to form a groove to inside, and the both sides of this groove also outwards are embedded with a slot.

Said lower cover, it is provided with several baffle region and is divided into the power supply terminal putting groove, and this putting groove is near opening part, and its dual-side is formed with outer angle of opening, and makes the outer plastic cement that covers be difficult for flowing into, and it is unimpeded to keep the passage of conducting terminal; And be a hollow upright square plug receptacle at the front end of power supply terminal, it is the upright square hole that corresponds to loam cake, the rear of this socket is to connect a clamp by a thin slice, this clamp is to combine and place with power line on the clamp placement section, and loam cake be formed with through hole after lower cover combines, this through hole is storing place of this thin slice; The dual-side of said lower cover is inwardly little curved and form a slot corresponding to holding section, loam cake both sides with the power supply terminal standing groove of below, the dividing plate outer edge surface that central authorities protrude, be be provided with corresponding on be covered on the engaging bar of slot in the groove, and the rear side of lower cover extends a clamp placement section as power supply terminal and power line in addition, the bottom of lower cover front end central authorities is outwards to convex with a barb, to be incorporated into the connecting hole of loam cake.

When assembling, power supply terminal is placed in the lower cover, the holding section of loam cake both sides outer rim is placed in corresponding lower cover slot, slot in the loam cake drop-center is placed in corresponding lower cover engaging bar, to push away the mode of track, loam cake is combined with lower cover, and the set barb of lower cover this moment then snaps in the set connecting hole of loam cake, promptly finishes the fixing action of assembling.

Advantage of the present utility model is: the one, and the utility model is made up of loam cake and lower cover engaging, between this loam cake and lower cover, be provided with corresponding engage rail and slot, corresponding connecting hole and barb, loam cake is the combination by engaging rail and pushing of slot with lower cover, interfix by the engaging of connecting hole and barb, therefore, loam cake can not make the power supply terminal in being held on come off because of falling back with after lower cover combines; The 2nd,, in lower cover, separate into three power supply terminals and put the dividing plate front end in district and be formed with outer angle of opening, make the outer plastic cement that covers be difficult for inflow, and it is unimpeded to keep the passage of conducting terminal; The 3rd,, after the mould manufacturing of upper and lower cover is finished, be to move back the mould mode about fireballing, can save die cost, to reduce production costs.
