Background technology
PDU (power distribution unit) single channel power supply and general supply connection mode in the products such as communication cabinet, power supply cabinet, mainly adopt screw to fix or welding manner at present.Screw is fixedly connected with in mode, and general supply three lines all adopt whole copper bar, are evenly distributed with the multi-wad join hole on copper bar, and one of the single channel wire is fixed in general supply by the connecting hole screw, and single channel wire other end is connected and draws power supply with socket; For guaranteeing can be for convenience detach, in the middle of wire, also to increase the negative and positive plug.Be welded and fixed in connected mode, general supply three lines all adopt wire, and total even stripping of wire has the exposed copper cash of multichannel, and one of the single channel wire by being welded to connect in general supply, and single channel wire other end is connected with socket; For guaranteeing can be for convenience detach, increase the negative and positive plug in the middle of wire.The major defect of said structure is: 1) adopt screw to fix or welding manner, workload is large, cost is high, maintenance is inconvenient; 2) the single channel tie point is many, and failure rate is high; 3) centre increases the negative and positive plug, the fault amount is large, cost is high.
The utility model content
The purpose of this utility model is the deficiency overcome in the above-mentioned background technology, and a kind of novel plug-in card clamping power supply attachment plug is provided, and this plug should have the characteristics that fault is few, dismounting is simple, easy to maintenance, cost is low.
For realizing above purpose, the technical solution adopted in the utility model is:
The attachment plug of Novel clamp clamping power supply is characterized in that: three claw type reeds that described clamp-type power connecting plug comprises pedestal and is fixed in pedestal; Middle part and the pedestal of described claw type reed are fixed, two inserted terminals that dangle and be arranged symmetrically with of claw type reed are bent into the plug-in elastic card jaws matched with the power supply copper bar, and the elastic card jaws of three claw type reeds is all toward same direction setting and aim at one by one the power supply copper bar that required grafting coordinates; Three claw type reeds also conduct by a wire and three core sockets respectively.
Described pedestal comprises base and the cover plate connected and fixed by card inserting structure and base; The inboard of cover plate also arranges one and presses solidly for top the briquetting of determining the claw type reed.
Described card inserting structure comprises several inclined platforms that symmetry is produced on several spliced eyes of base side and is produced on the cover plate side and coordinates one by one respectively with described spliced eye.
Described seating plane is manufactured with three slots to the position of power supply copper bar, and the inserted terminal of described three claw type reeds is positioned at respectively in three slots one by one; The position of three slots matches one by one with three power supply copper bars simultaneously, and the width of each slot all is greater than the thickness of described power supply copper bar.
The notch of described slot is made into has the tubaeform of guide effect.
Be made into two distances that neither wait with inverse plugging effect between described three slots.
The beneficial effects of the utility model are: the attaching plug provided has adopted the plug-in card clip structure that can contact with power supply copper bar elastic clamping reliably, not only simplify the structure and (replaced original screw and fixed or be welded and fixed structure, saved the negative and positive plug), and have that fault point is few, easy to maintenance, assembling and disassembling simple and flexible, highly versatile, hot-pluggable maintenance, low cost and other advantages, can be widely used in the products such as communication cabinet, power distribution row cabinet, electric power equipment cabinet.

Fig. 3 is working state schematic representation of the present utility model.
Embodiment
Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model is not limited to following examples.
As shown in the figure, the clamp-type power connecting plug that the utility model provides, comprise cover plate 1, base 2, claw type reed 3(3), copper conductor 4(3 root).Cover plate 1 and base 2 injection mo(u)ldings, and coordinate and form pedestal by card inserting structure fastening, the claw type reed be fixed in pedestal (by fire resistance good and resistant to elevated temperatures plastic casing be fixed, spacing, guarantee to insulate and heatproof).The card inserting structure comprises that symmetry is produced on several spliced eyes of base side and is produced on the inclined platform 1-1 that the cover plate side coordinates one by one with described spliced eye; Known in Fig. 2: two side positions of base are manufactured with respectively 3 spliced eyes (both sides of each claw type reed are the corresponding spliced eye of arranging respectively), the inclined platform of cover plate two sides one by one with described spliced eye corresponding matching.Three claw type reeds respectively with wire 4(3 root wire, be respectively live wire L, zero line N, ground wire PE; The recommend adoption copper conductor) be welded and fixed, cover plate covers rear fastening base, and the briquetting 1-3 of cover plate inboard just top is pressing the claw type reed, and the claw type reed is fixed in pedestal; The elastic card jaws of three claw type reeds is all toward same direction setting and aim at one by one PDU (power distribution unit 7) the power supply copper bar 5 that required grafting coordinates; On three core sockets 6 of the other end of wire insertion standard from plug is drawn, form a complete clamp-type power connecting plug.
For the safety (guaranteeing during insertion that working of plastics first contacts with the power supply copper bar) of guaranteeing the process that plugs, described seating plane is opened and is shaped with three slot 2-1 the position of power supply copper bar, and the width of each slot all is greater than the thickness of described power supply copper bar; And all arrange the inserted terminal (the only part exposure in slot of claw type reed) of a claw type reed in each slot; The position of three slots matches one by one with three power supply copper bars simultaneously, realizes being electrically connected to the reliable of PDU.Guide to standard three core sockets 6 by the clamp-type power connecting plug from single phase poaer supply, just can realize complete, effective electrical connection.Only the clamp-type power connecting plug need be extracted and got final product from power supply copper bar 5 in the time of need to safeguarding, can not affect other branch road and use.
Further, the notch 2-11 of described slot also makes has the tubaeform of guide effect, in order to plugged smoothly, reliably operation.
Further again, (as shown in Figure 1: the distance of b is greater than a), can guarantee not wrong plug (having the inverse plugging effect) in the other direction to be made into two distances that neither wait between described three slots.
The utility model is by claw type reed 3(claw type reed buyable or self-control on the clamp-type power connecting plug; Can adopt good and Cu alloy material good springiness of electric conductivity to make), copper bar 5, three core sockets 6 on wire 4 and PDU form reliable electric and connect, wherein claw type reed and copper bar 5 form reliable Elastic Contact by clamping force, reach the electrical contact dependable performance, installation, maintenance facilitates texts, but has that fault point is few, easy to maintenance, a highly versatile hotline maintenance, low cost and other advantages.
Wire 4 described in the utility model, copper bar 5, three core sockets 6 are ripe general commercially available prod, and the national standard requirement is all arranged, and directly outsourcing is used.
