Description

Terminal with arc clamp chip

Technical field

The utility model belongs to electric connecting element, particularly a kind of terminal with arc clamp chip.

Background technology

Electronics industry is to lead many industry to move towards epochal one of the staple industries at present, and its development speed makes rapid progress.Wherein, computer industry is leading especially, its periphery and various device accessory tinkling of jades the meeting the eye on every side of can saying so, with regard to with regard to the terminal that connects usefulness, though its volume is little, the structure of each one own is if design is improper, just cause inconvenience in the use easily, so can not be careless.

As shown in Figure 1, known terminal 10 mainly has the tube seat 11 that supply lines is inserted, the one ora terminalis is provided with the cramp 13 that is used to clamp the pincers sheet 12 of electric wire outer ring rubber-insulated wire and is used for clamping electric wire internal core wire 30, be provided with at the bottom of its other end near-end edge and lack hole 14, and lack hole 14 1 sides certainly and extend catch 15, lack on 14 two sides, hole and be provided with amphicoelous contact point 16 in addition; Be provided with open-work 17 and block holding part 18 in two sides, terminal 10 middle section; Block holding part 18 cordings have relative lateral surface to form the folding line of depression.By this electric wire is placed in the tube seat 11 of terminal 10, respectively by the outer rubber-insulated wire and the internal core wire 30 that clamp sheet 12 and cramp 13 securing electric lines, and, make heart yearn 30 be able to contact to reach conducting with contact point 16 and catch 15 with the extruding of contact point 16 ecto-entads of terminal 10 front ends.While actually employed by the fixing of two block holding parts 18 and connect the interface slotted eye of terminal, and reaches the purpose of connection.

But extending in both sides, middle section open-work 17 inner side edges, the terminal of commonly using 10 provides folding line and the pointed block holding part 18 of terminal formation.As shown in Figure 2, when embedding in the terminal interface slotted eyes at terminal 10, push difficultly, must impose the purpose that bigger strength can reach engaging.And in case after embedding, because block holding part 18 is terminal pointed, it is uncertain to cause fastening effect easily; Again in order to increase the intensity of block holding part 18, and therefore the concave face that forms in a side has also and manufactures the disappearance that is difficult for.Moreover as shown in Figure 3, in the time of in electric wire embeds tube seat 11, system is inboard extruding from terminal 10 front end laterals, so that contact point 16 contacts with heart yearn 30 respectively with the catch 15 that is arranged at terminal 10 front ends, but catch 15 and contact point 16 form single-point with heart yearn 30 and contact, thereby when the combination of using at repetitiousness because of terminal 10 easily, dismounting, produce the situation of loose contact, cause terminal 10 to lose the effect of conducting.

Summary of the invention

The purpose of this utility model provide a kind of easy to manufacture, plug conveniently, fasten the terminal that effect is certain, serviceability is good with arc clamp chip.

But the utlity model has the groove that supply lines wears; Its rear end is provided with pincers sheet and the cramp that is respectively applied for clamping wire outer skin line and internal core wire; Its stage casing and front end are respectively equipped with through hole and open-work; Through hole leading edge side extends backwards and is arcuation and the flexible clamp chip of tool; Open-work leading edge side extends holding piece backwards; The open-work both sides form two relative cancave cambered surfaces.

Wherein:

Clamp chip is terminal to be formed and the parallel applying plane of terminal interface slotted eye inwall.

Correspondence is formed at open-work two sides cancave cambered surface and forms down shallow going up deeply.

Holding piece near-end edge is the recess with certain sinking degree.

But owing to the utlity model has the groove that supply lines wears; Its rear end is provided with pincers sheet and the cramp that is respectively applied for clamping wire outer skin line and internal core wire; Its stage casing and front end are respectively equipped with through hole and open-work; Through hole leading edge side extends backwards and is arcuation and the flexible clamp chip of tool; Open-work leading edge side extends holding piece backwards; The open-work both sides form two relative cancave cambered surfaces.Heart yearn is arranged in the utility model groove, and the utility model two side is pushed towards the center, the utility model and heart yearn are reached combine fixing, and make holding piece and cancave cambered surface contact with heart yearn formation face respectively, in order to the conducting effect.During connection, the utility model that wears heart yearn is inserted in the terminal interface slotted eye, can be fastened in really in the interface slotted eye, reaching firm grafting, and have by this and prevent to paste the effect that falls, difficult drop-off by being the flexible clamp chip of arcuation and tool; By cancave cambered surface and holding piece and heart yearn all formation face contact, it is good to have a better conductive effect.Not only easy to manufacture, plug conveniently, and fasten that effect is certain, serviceability good, thereby reach the purpose of this utility model.

Embodiment

As Fig. 4, shown in Figure 5, but the utility model 20 has the groove 21 that supply lines wears.

The utility model 20 end edges are provided with the cramp 28 that is used to clamp the pincers sheet 27 of electric wire outer ring rubber-insulated wire and is used for clamping electric wire internal core wire 30.

Both sides, the utility model 20 middle section are provided with through hole 22, and extend backwards in through hole 22 leading edge sides and to be arcuation and the flexible clamp chip 23 of tool; Clamp chip 23 terminal formation and the parallel applying plane 231 of terminal interface slotted eye inwall.

The utility model 20 nearby ora terminalis bottom surface is provided with open-work 24, and open-work 24 leading edge sides extend holding piece 25 backwards, and holding piece 25 near-end edge are the recess with certain sinking degree; Open-work 24 both sides form two relative cancave cambered surfaces 26, and the sinking degree of cancave cambered surface 26 is for shallow dark down.

As shown in Figure 7, heart yearn 30 is arranged in the utility model 20 grooves 21, and the utility model 20 two sides are pushed towards the center, the utility model 20 and heart yearn 30 are reached combine fixing, and make holding piece 25 and cancave cambered surface 26 contact with heart yearn 30 formation faces respectively, in order to the conducting effect.

During connection, will wear the utility model 20 of heart yearn 30 insert in the terminal interface slotted eyes, can be fastened in really in the interface slotted eye by the clamp chip 23 on terminal tool applying plane 231, reaching firm grafting, and have by this and prevent to paste the effect that falls.

The utlity model has following advantage:

1, difficult drop-off; When the utility model 20 is incorporated into terminal interface slotted eye, by tool elasticity and be the clamp chip 23 of arcuation, the utility model 20 can be embedded in the terminal interface slotted eye easily, and after embedding, also fit with the slotted eye internal face in its terminal applying plane 231 that forms, with the effectiveness that obtains to fix really, and terminal unlikely as that commonly use is excessive because of the block holding part bending angle, must impose big strength can embed, and because of its terminal pointed formation fixes untrue situation, the utility model 20 clamp chips 23 can easily embed the utility model 20 smoothly in comparison, and can reduce the probability that comes off.

2, conductive effect is good: the holding piece 25 of the utility model 20 is to be located at open-work 24 central authorities and ora terminalis to form the angle that to a certain degree caves in, and open-work 24 two sides be provided with down shallow dark cancave cambered surface 26, when heart yearn 30 is clamped in the groove 21 of the utility model 20, because the cancave cambered surface 26 of both sides caves inward and the holding piece 25 of bottom surface is upwards propped up, make its with heart yearn 30 all formation face contact, thereby contact with the point of commonly using terminal and to compare, it is good to have better conductive effect certainly.
