Abstract

The utility model relates to a fixed device for copper knifes of tail inserting lead wires. Mainly, a tail inserting internal sleeve and an external sleeve are elastically buckled to form a stable sheath and clamp lead wires. In addition, a copper sheet are fixed by a fixed slot and a projecting part arranged in the internal sleeve for matching, so as to achieve double safety effect that lead wires of a lamp string are stably clamped at the inner part of a socket and that the copper sheet does not need to consider about displacement.

Description

Fixed apparatus for copper knife of tail lead

Insert by the lamp string tail of generally commonly using; only will be positioned over tail with the copper sheet of wire-bonds merely inserts in the interior set groove; so copper sheet does not have firm fixation; regular meeting has the situation of rocking to exist; and the copper tool that causes copper sheet and plug forms unsettled safety worries when contacting conduction, and lead and tail are slotting in addition combines the fastening that also only depends on lead and copper sheet tail end terminal; so also Chang Yi causes tail to insert and wire dropping in use, and the misgivings on the safety are arranged.

In view of this, at old product safety defect, main purpose of the present utility model is that a kind of stable clamping effect that forms by the elasticity fastening structure of inside and outside cover lead is provided.

And a time purpose of the present utility model be with copper sheet is stable be sheathed in the set groove of cover, and copper sheet is not had rock the safety operation effect of situation.

The purpose of this utility model is realized by following technical scheme.

In sum, the utility model compared with prior art advantage is, by the effect of well-designed fixedly ditch and projection, and reaches the effect of stablizing clamping, obviously significantly improves and commonly uses the defective that tail is inserted, and practical effect significantly increases, and fail safe also promotes significantly.

Concrete structure of the present utility model is provided in detail by following examples and accompanying drawing thereof.

Fig. 1 is a schematic appearance of the present utility model.

Fig. 2 is a three-dimensional exploded view of the present utility model.

Fig. 3 is a floor map of the present utility model.

Fig. 4 is a plane of the present utility model fit action schematic diagram.

Fig. 5 is a three-dimensional cut-away section schematic diagram of the present utility model.

As Fig. 1, shown in Figure 2, the utility model mainly is by overcoat 1, interior cover 2, lead 3, copper sheet 4 constitutes, wherein overcoat 1 is the shell of a hollow, one end is that big opening 11 is in order to cover 2 in the fit, the other end is little opening 12, little opening 12 is respectively equipped with hook part 121 in its inner, both sides, and be provided with two salient points 122 by middle appropriate location in its lower surface, and be equipped with a fin 13 in the both sides up and down of inside, 2 internal structures of interior cover as shown in FIG., wherein mainly be that at one end face is provided with the inlet 21 of two plug copper tools, the other end then is provided with outside unsettled extension and slightly is three

parallel projections

22,23,24, wherein

projection

22,23 are respectively equipped with buckling parts 221 in its opposite external side face, the outside end face of 231 projections 24 then slightly is up-thin-low-thick " protruding " word shape, cover 2 mid portions are provided with and hold copper sheet 4 in addition, the groove 25 of lead 3, the fixing fixedly ditch 26 of copper sheet 4 tail ends, reach the fixedly protuberance 27 in copper sheet 4 stage casings, lead 3 is power lines that general lamp string uses, it is to combine with general manner with copper sheet 4 one ends, copper sheet 4 is a turning point 41 in the other end of its buckling end, both sides, appropriate location are respectively equipped with recess 42 in the middle of it, when the utility model in conjunction with when assembling, lead 3 is inserted in the groove 25 of interior cover 2 with copper sheet 4, and turning point 41 and recess 42 are snapped in fixedly in the ditch 26 and protuberance 27 respectively, make copper sheet 4 form stable setting, make lead 3 be inserted in three projections 22 in addition, 23, in the gap in the middle of 24, and this gap is to equate with the diameter of lead is rough, penetrate the opening 11 of overcoat 1 then, 12, when penetrating opening 12, restriction because of hook part 121, cause buckling parts 221,231 is own to mid portion compression and effect main traverse line 3, and when crossing hook part 121, buckling parts 221,231 promptly are fastened on hook part 121 because of restriction disappearance resilience, therefore in making, overcoat 2,1 fit forms stablizes inseparable combination, because of in if operation being arranged external force desiring to make, overcoat 2, during 1 separation, unless surmounting the rigidity of material itself, external force damages, buckling parts 221,231 are subjected to lead 3 diameter restrictions with the fastening of hook part 121, the phenomenon that can cause resilience to get loose not, in addition copper sheet 4 is because of being subjected to the fixedly restriction of ditch 26 and protuberance 27, and fin 13 is directly oppressed from top, when manipulating, do not have a displacement or a left side yet, rock on the right side, causes the misgivings of security threat.

And structure of the present utility model does not also have disclosed true the existence, and novelty can affirm that also according to the regulation of Patent Law, the utility model proposes patent application in accordance with the law.

Claims

1, a kind of tail lead copper tool fixture mainly is made up of overcoat, interior cover, lead, copper sheet, it is characterized in that wherein overcoat is a hollow shell, and two ends are provided with opening, and are provided with two hook parts and two protuberances in less openend; In be placed in mid portion and be provided with groove, fixedly ditch, protuberance, and be provided with three slightly parallel outward extending projections at nearly overcoat end, lead be the power line of general use; The other end of copper sheet and wire-bonds forms a turning point, and the both sides, appropriate location are provided with recess in the middle of it, by above-mentioned combination, in overlapping in copper sheet and lead fixed are located at, and lead is stretched out in the gap of three projections, in overlap then the buckling parts of mat projection and the hook part of overcoat and finish fastening, and form the stable combined structure that can not rock.

2, tail lead fixed copper knife system according to claim 1 is characterized in that, wherein is provided with the overcoat of two salient points and the interior cover of middle projection, when combination is finished, and can be with lead fixed in middle appropriate location.
