In sum, the DC power supply connector electric property of existing structure is understable, and ground connection that can not be good.In view of this, necessary existing DC power supply connector construction is improved, to overcome above-mentioned defective.
[summary of the invention]
The main purpose of the utility model is to provide a kind of DC power supply connector; Through set grab the shape terminal not only can with the connection-peg negative pole is contacted earlier; Can also chucking power be provided to connection-peg; Guarantee the maintenance tightness of this connector, to realize the electrical transmission stability of this DC power supply connector to connection-peg.
The utility model above-mentioned purpose and the technical scheme of dealing with problems are realized by following technical scheme: a kind of DC power supply connector comprises insulating body, is coated on the surperficial metal shell of insulating body, is placed in anodal conducting terminal and negative pole conducting terminal in the insulating body.Described negative pole conducting terminal is grabs shape; Set plural grip flaps is distributed in the ring-type disjunctor portion; Each grip flaps is equipped with contact site, and has at least a grip flaps contact site more to be close to insulating body front end face interface compared to the set contact site of other grip flaps in the set plural grip flaps.The connection-peg that can guarantee this power connector and pairing like this negative pole when inserting contacts earlier conducting.Simultaneously can be clamped on the connection-peg annular recess that plugs this connector, provide chucking power to guarantee maintenance tightness to connection-peg compared to insulating body interface each grip flaps contact site far away.
Described negative pole conducting terminal also is provided with plural hangnail in ring-type disjunctor portion, make firm the remaining in the set annular channel of insulating body rear end face of negative terminal.And be provided with welding foot along disjunctor portion one side, realize the negative pole circuit switch with this.
So, this power connector is not only simple in structure, and electric property is stable when using.

[embodiment]
For ease of specifying the enforcement structure of the utility model, combine accompanying drawing that the utility model is explained as follows in detail at present:
Like Fig. 1, shown in 2, a kind of DC power supply connector, comprise insulating body 1, be coated on insulating body 1 surface metal shell 4, be placed in negative pole conducting terminal 2 and anodal conducting terminal 3 in the insulating body 1.Insulating body 1 is provided with spliced eye 10 in the front end face center position, is provided with the conduit 11 that plural number connects along rear end face around spliced eye 10 inwalls, and conduit 11 intersects with spliced eye 10.Also be provided with annular channel 12 in insulating body 1 rear end face, fixing for negative pole conducting terminal 2.The anodal conducting terminal 3 employing injection mo(u)ldings of this embodiment are fixed in insulating body 1 and are remained in the spliced eye 10.
As shown in Figure 3; Described negative pole conducting terminal 2 is by the moulding of sheet metal component integrated punching grabs shape; Set plural grip flaps 23,24 is extended to form by ring-type disjunctor portion 20 1 sides, is one by one that symmetry shape is distributed in the ring-type disjunctor portion 20, and has been bent to form contact site 231,241 in each grip flaps 23,24 end; And contact site 241 is compared contact site 231 further from ring-type disjunctor portion 20; With reference to shown in Figure 4, just this negative pole conducting terminal grip flaps 23,24 stretches in the spliced eye 10 along insulating body conduit 11 simultaneously, and grip flaps contact site 241 more approaches insulating body front end face interface 101.
These terminal 2 ring-type disjunctor portions 20 are fixed in (as shown in Figure 2) insulating body annular channel 12 through hangnail set on it 21 clips, thus make negative pole conducting terminal 2 grip flaps 23,24 around anodal conducting terminal 3 firm be fixed in insulating body 1.And expose to this 1 body of insulation by weld part 22 set in the ring-type disjunctor portion 20 and carry out circuit and connect.
It is as shown in Figure 5 that (explain: subsequent figures insulating body 1 is illustrated with dotted line; Be convenient to internal structure is described); Connection-peg 5 these power connectors of insertion when coupling; When anodal 52 desires of connection-peg contacted with the anodal conducting terminal 3 of this connector, negative pole conducting terminal grip flaps 24 contact sites 241 contacted with connection-peg negative pole 51 earlier, carry out circuit by weld part 22 and connect; Negative pole contact earlier conducting when slotting with 5 pairs of the connection-pegs of realizing this DC power supply connector and pairing, to avoid the circuit voltage generation burning machine phenomenon that increases severely.
As shown in Figure 6; When described connection-peg 5 is inserted into the position fully; Can be clamped on the annular recess 53 of the connection-peg that plugs 5 compared to interface each grip flaps 23 contact site 231 far away; So that chucking power to be provided, guarantee the maintenance tightness of this power connector, to realize stable electrical transmission to connection-peg 5.When the moment that 231 pairs of these annular recess 53 of grip flaps 23 contact sites are carried out clamping, can produce clickly feel simultaneously, pegging graft with indication connection-peg 5 puts in place.
Be familiar with enforcement creation purpose and the effect that this operator understands the utility model spirit strictly according to the facts for making; Embodiment that is lifted and accompanying drawing only are that the utility model is explained; Not to the utility model any restriction in addition; So allly be familiar with this operator and carry out other pattern under the utility model spirit and implement not breaking away from, the equivalence that all should be regarded as this case claim is implemented.
