Line ball formula lamp holder
Technical field
The utility model relates to the illuminating lamp lamp holder, refers in particular to a kind of bayonet type or screw type lamp holder that linear system is fixed by conductive cap that conduct electricity.
Background technology
In illuminating lamp lamp holder field, no matter be bayonet cap or screw cap, wherein conductive cap system is fixed on the glass insulator top, conductor wire is to adopt welding manner to fixedly connected with conductive cap usually, so cause the problem of not environmental protection because of scolding tin, and welding sequence is also loaded down with trivial details, is unfavorable for production and processing; By this, industry demands improving above-mentioned disappearance urgently, so have the insider to propose to adopt between conductor wire and the conductive cap various affixed modes such as riveted joint, still, all there is the phenomenon of conductor wire wiring instability in existing affixed mode, phenomenons such as loose contact appear easily, fail safe is low, and especially built-in structure is also complicated, and operation is still numerous and diverse, assembling inconvenience brings certain puzzlement to industry.
The utility model content
The utility model is at the existing disappearance of above-mentioned prior art, main purpose be to provide a kind of simple in structure, assembly convenient, affixed stable and safe line ball formula lamp holder.
For realizing above-mentioned purpose, the utility model is taked following technical scheme:
A kind of line ball formula lamp holder, comprise metal valve jacket, insulator, conductive cap and conductor wire, this insulator is embedded at metal valve jacket top, and this conductive cap is fixedly arranged on insulator head, the downward one of described conductive cap periphery is extended with a plurality of fixing sheets, and this fixing sheet side is provided with hangnail; Described insulator head is provided with location hole to fixing the sheet position, makes to fix in this location hole of the corresponding embedding of sheet; Described insulator head is cambered surface by the line ball zone that conductive cap covers, and is provided with the first line hole in it, and the line end of described conductor wire passes this first line hole and pressed between conductive cap and insulator head, and line end is electrically contacted with conductive cap.
The surface system in described line ball zone is made as latticed, so that the friction between increase of the line end of conductor wire and insulator more can be compressed line end by conductive cap.
Also be provided with the second line hole in the described line ball zone, the bending of line end extension is penetrated in this second line hole, make line end reach the effect of affixed stability better.
Described insulator is plastics or bakelite material, is convenient to provide conductive cap affixed better.
The utility model advantage is: the conduction linear system directly compresses affixed mode with conductive cap, conductor wire is pressed between conductive cap and insulator head, and being fixing sheet by periphery, conductive cap directly embeds in the location hole of insulator, system is interfered firm by the hangnail that fixes sheet, so conductive cap and conductor wire assembly are convenient, and be affixed stable and safe.Further also can make latticed by the line ball region surface to increase the friction between conductor wire and insulator, perhaps also can adopt the second line hole to provide the line end extension of conductor wire to penetrate, so the line end of conductor wire is under conductive cap is being pressed state, and its line end is more firm.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
See also Fig. 1 to shown in Figure 7, present embodiment system describes with bayonet cap; A kind of line ball formula lamp holder comprises metal valve jacket 1, insulator 2, conductive cap 3 and conductor wire 4, wherein:
Metal valve jacket 1 is a bayonet type, and both sides have metal bail 11, for the lamp socket clamping.
Insulator 2 can adopt plastic material or bakelite material to make, and is convenient to provide conductive cap 3 affixed better; Wherein this insulator 2 is to be embedded at metal valve jacket 1 top.Be provided with two line ball zones 22 at insulator 2 tops, this line ball zone 22 is cambered surface, is provided with location hole 21 around each line ball zone 22.Be provided with the first line hole 221 and the second line hole 222 in described each line ball zone 22.
Conductive cap 3 has two, and it is fixedly arranged on insulator 2 tops respectively, and the corresponding line ball zone 22 that covers; The downward one of described conductive cap 3 peripheries is extended with the fixing sheet 31 of two symmetries, and these fixing sheet 31 sides are provided with hangnail 311; Wherein fixing sheet 31 is that corresponding described insulator 2 top location holes 21 embed, and is to interfere firm by hangnail 311 that fixes sheet 31 sides and location hole 21 inwalls.
Conductor wire 4 correspondences are provided with two, after the line end 41 first correspondences of every conductor wire 4 are passed the first line hole 221 in each line ball zone 22, pressed between conductive cap 3 and insulator 2 tops, and extension 411 bent the penetrating in the second line hole 222 of line end 41, line end 41 is fully contacted with conductive cap 3, can reach the effect of affixed stability.
The surface in described line ball zone 22 system can be made as latticed, so that the line end 41 of conductor wire 4 increases and the friction of 2 of insulators, line end 41 more can be compressed better by conductive cap 3.
Wherein, the utility model assembly is as follows: earlier that metal valve jacket 1 and insulator 2 is affixed, again line end 41 correspondences of each conductor wire 4 are passed the first line hole 221 in line ball zone, insulator 2 top 22, make line end 41 bendings be positioned at 22 surfaces, line ball zone, affixed for realizing better, the extension 411 of line end 41 can be bent again and penetrate in the second line hole 222; And then the location hole 21 at fixing sheet 31 corresponding insulators 2 tops of conductive cap 3 directly buckled into, interfere fixingly by the hangnail 311 that fixes sheet 31, conductive cap 3 covers line ball zones 22 thus, and conductor wire 4 is pressed between conductive cap 3 and insulator 2 tops.
The utility model design focal point is in the location hole 21 of conductive cap 3 by the fixing sheet 31 corresponding embedding insulators 2 of periphery, system interferes firm by the hangnail 311 that fixes sheet 31, be to press on insulator 2 tops simultaneously by the line end 41 of this conductive cap 3 with conductor wire 4, conductor wire 4 can fully be contacted with conductive cap 3, so conductor wire 4 is to adopt conductive cap 3 directly to be fixed mode, its assembly is convenient, and good stability is safe.Further, also make latticed to increase the friction of conductor wire 4 by 22 surfaces, line ball zone, perhaps also can adopt the second line hole 222 to provide line end 41 extensions 411 of conductor wire 4 to penetrate, so the line end 41 of conductor wire 4 is being pressed under the state at conductive cap 3, and its line end 41 is more firm.
The above, it only is the preferred embodiment of the utility model structure, be not that technical scope of the present utility model is imposed any restrictions, for example the utility model also is fit to the screw type lamp holder, do not add to give at this and enumerate, so every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any trickle modification, equivalent variations and modification that above embodiment did.
