Description

Power connector

Technical field

The present invention relates to electrical connector, relate in particular to a kind of for electronic product power, can mate lastingly, stable, socket and the complete novel power supply connector of plug.

Background technology

Supply socket is widely used in electric equipment products, such as portable sound equipment, audio-visual projector (such as VCD, DVD etc.) and information products (such as computer, notebook computer, mobile phone etc.), be supply socket and the commercial power socket of the power line difference intercalation product of plug by two ends, make this product be able to continuous electric energy supplement, to keep the required of product normal operation.

Such as Figure 11 and shown in Figure 12, three-dimensional exploded view and the side cutaway view of the existing socket of commonly using, it comprises insulating body A, the first conducting terminal B and the second conducting terminal C, in insulating body A, be formed with to accommodate the host cavity A0 of the butted part that docks external plug, and in order to accommodate first, the plural number first accepting groove A1 of the second conducting terminal, plural number the second accepting groove A2, this is first years old, the second conducting terminal has the main part B1 that is contained in the insulating body accepting groove A1, C1, and autonomous body B1, the holding parts B2 that the C1 level extends to form forward, C2, from holding parts B2, the docking section B3 that first outward-dipping extension of C2 bends inwards and extends to form, C3, and docking section B3, C3 is that one extends in the aforementioned host cavity A0 and can contact with the butted part of aforementioned banjo forward, wherein the docking section B2 of the first conducting terminal B is uniformly distributed on the first periphery and bends inwards and extends and form, the docking section C2 of the second conducting terminal C is uniformly distributed on the second periphery and outward extends and forms, the first periphery is positioned at the periphery of the second periphery, because of first, the second conducting terminal B, the elasticity docking section B2 of C, C2 is inside and outside bilayer and evenly distributes, the support force of banjo with balance can be provided, guarantee the stability of electric power transfer.

Yet still there is the following perfect disappearance of not attaining in above-mentioned socket when using:

(1) first, the second conducting terminal B, C all is by circular body portion B1, the C1 level extends to form forward a plurality of holding parts B2, C2, from each holding parts B2, the docking section B3 that the outward-dipping extension of C2 bends inwards and extends to form, C3, make docking section B3, the opposite direction that the butted part of C3 bearing of trend and banjo inserts, make the grafting process form reverse pushing, can make docking section B3, the suffered pushing force of C3 is towards extruding holding parts B2, the position of C2, make holding parts B2, C2 is pushed and is produced deformation, relatively form resistance and affect docking section B3, the swing situation of C3, cause docking section B3, C3 can form swing crooked and that depart from, so that the butted part of banjo and docking section B3, C3 has blocking or the bad problem of contact condition during contact, causes high-drag, grafting is difficult and stable contact can't be provided, transmission power supply effect.

The whole complex structure of (2) second conducting terminal C and can't miniaturization, must extend to form forward plural holding parts C2 in circular body portion C1 one side level, and more outward-dipping extension and bend inwards and form the docking section C3 of the shape that arches upward of each holding parts C2, each docking section C3 forms the lower structure of single sheet intensity, on processing and fabricating, must use the large tracts of land flaky material to make, through cutting, the too much procedures such as bending are made a plurality of docking section C3, cause the problem of raising and the consumptive material waste of material cost, and the insulating body A structure that configures must larger space be set in inside and the second complicated accepting groove A2 configuration is installed for it, so that operation procedure can't be simplified and save to the program that this insulating body A makes, time and cost.

Be with, how to solve the disappearance of above-mentioned prior art, be the correlative study person who is engaged in the industry and desire most ardently the direction place that research improves.
