Above-mentioned conductive cap is that metal material is made, and its reference column outer surface is provided with the evagination lines that cooperates with the hollow via-hole close-fitting.

This evagination lines is shape of threads.

Above-mentioned reference column is to be extended by cap body center to form.

Above-mentioned conductive cap is coated with the plastic parts of metal level for the outer surface vacuum, and its reference column top is provided with the overhead kick portion of back-off in the hollow via-hole end wall that be used for.

Above-mentioned hollow via-hole is non-circular poroid, and corresponding reference column is non-circular column.

The utility model compared with prior art, its advantage is to adopt squash type fixedly conductive cap and conductor wire in the lump, avoids soldering tin technique, so easily assembly, the efficient height, cost is low, and environmental protection again.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

As shown in Figure 1, a kind of lamp holder comprises insulator 1, metal casing 2, conductive cap 3 and conductor wire 4, wherein:

Insulator 1 is made for plastic material, and its crown center position offers hollow via-hole 11 and offers a line hole 12 at least in these hollow via-hole 11 peripheries, this line hole 12 for conductor wires 4 can place design.

Metal casing 2 and above-mentioned insulator 1 are affixed, and it is can finish for prior art, is not the utility model emphasis, does not add at this and gives detailed description.

Conductive cap 3 is made by metal material, and it comprises cap body 31 and along cap body 31 centers and the reference column 32 that extends of vertical cap body 31 one, these reference column 32 outer surfaces are provided with and hollow via-hole 11 close-fitting evagination lines 321, for example are shape of threads; Wherein this reference column 32 is to be pressed in the above-mentioned hollow via-hole 11, and and 11 formation of this hollow via-hole structure that closely cooperates, present embodiment is promptly interfered mutually by evagination lines 321 and hollow via-hole 11 inwalls and is formed fixed effect.The top of cap body 31 is exposed to outside the insulator 1.

Insert in conductor wire 4 holes 12 along the line, and its line end 41 is that the cap body 32 by conductive cap 3 compresses to form and fixes and be electrically conducted structure.

During assembly, earlier conductor wire 4 holes 12 along the line are inserted, but make line end 41 be positioned at cap body 31 overlay areas of conductive cap 3, reference column 32 with conductive cap 3 is extruded directly in the hollow via-hole 11 at insulator 1 top again, evagination lines 321 and hollow via-hole 11 inwalls interference formation location by reference column 32, be the line end 41 that compresses conductor wire 4 by cap body 32 simultaneously, and then form purpose fixing and that can be electrically conducted again.So need not scolding tin and fix, assembly is easy, and cost is low, efficient height, and environmental protection again.

Again as shown in Figure 2, it is another execution mode of the utility model lamp holder; The same system of the lamp holder of present embodiment comprises insulator 1, metal casing 2, conductive cap 3 and conductor wire 4, and this insulator 1 is to be made by plastic material, and its top offers a hollow via-hole 11 and line hole 12, and this hollow via-hole 11 is non-circular poroid; Constitute and conductive cap 3 is the plastic parts that is coated with metal level by the outer surface vacuum, carry out vacuum plating after its one is injection molded, this way is can realize for prior art, does not add at this and gives detailed description.These conductive cap 3 same systems comprise cap body 31 and reference column 32, and this reference column 32 is non-cylindric for cooperating hollow via-hole 11 to be designed to, and so reference column 32 is squeezed into to form in the hollow via-hole 11 and closely cooperates, and the phenomenon that can not rotate; Be provided with the overhead kick portion 322 of back-off that be used on these reference column 32 tops, reference column 32 is positioned in the hollow via-hole 11 in hollow via-hole 11 end walls.So insert in conductor wire 4 holes 12 along the line, its line end 41 is that the cap body 31 by conductive cap 3 compresses, and makes the metal level electric connection of itself and cap body 31 outer surfaces.The plastic parts that present embodiment and previous embodiment emphasis difference adopt the outer surface vacuum to be coated with metal level is replaced the conductive cap that metal material is made, for cooperating actual production, reference column, hollow via-hole are designed to non-circular configuration, system is identical with previous embodiment during assembly, does not add to give at this and repeats to set forth.

The fixedly design of conductive cap and conductor wire in the lump when the utility model design focal point is to closely cooperate by the default hollow via-hole employing squash type of default reference column of conductive cap and insulator head, can avoid soldering tin technique, so easily assembly, efficient height, cost is low, and environmental protection again.

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, 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.
