Description
Technical field
The invention belongs to lighting technical field, is related to a kind of LEDbulb lamp.
Background technology
It is well known that lamp holder is used as the connection member of bulb and lamp socket, traditional lamp holder either screw type still blocks
Mouth formula lamp holder, its conductor wire are to form the purpose being electrically conducted by the way that scolding tin mode and conductive cap are affixed.However, scolding tin cost
Higher, operation inconvenience, efficiency of assembling is low, and the pollution of environment can be caused during scolding tin, it is clear that does not meet current promotion
The demand of environmental protection.At present, also there are some improved lamp holders in the market, and it uses the conductive cap of drawing pin shape directly to squeeze conductor wire
Pressure is fixed, and for the relatively conventional scolding tin connected mode of the fixed connected mode of this extruding, has convenience and the feature of environmental protection.So
And have been found that its own structure has still suffered from many deficiencies when actual production assembles, fail to reach optimal packaging efficiency and
Convenience, specific defect are as follows：In the drawing pin cap extruding fixed structure of existing conductor wire, have the fixing hole that is provided separately and
String holes, consequently, it is possible to the structural complexity of insulation forming die is not only increased, and also its string holes is around fixing hole peripheral hardware
Put, the wall portion for also resulting in the fixing hole is only connected by several connection sheets with insulator, and then has influence on the knot of fixing hole wall portion
Structure intensity；For the porch that conductor wire penetrates it is right-angle type design in addition, existing, the entrance opening dimension of string holes is too small, during assembling
Conductor wire is not easy to insert, and so as to influence packaging efficiency, does not adapt to the needs of automatic assembling operation especially, it is competing to be unfavorable for market
Strive.
Therefore, someone has invented a kind of lamp holder [U of Authorization Notice No. CN 201829468] to solve to lead in existing lamp holder
The problem of electric wire is not easy to insert and cause to assemble inconvenience, it includes insulator, metal casing, conductive cap and conductor wire, and this is exhausted
The center of edge body offers fixing hole, and the lower ending opening of fixing hole is the whole bell-mouth structure of air for enclosing periphery and outwards gradually expanding, and is led
The terminals of electric wire are inserted in fixing hole by the horn mouth from bottom to top；Conductive cap include cap body and in the middle part of the cap body vertically downward
The locating dowel that one extension is formed, locating dowel is pressed into the fixing hole from top to bottom by the upper end open of fixing hole, and locating dowel
Formed between fixing hole and be fitted close and be fixed the terminals of conductor wire.
Above-mentioned lamp holder is to make conduction using special formed bell-mouthed inclined-plane to provide the guide function of conductor wire assembling
The assembling of line is more easy to find the assembling entrance of fixing hole, is more suitable for the assembling operation of automation equipment.But this lamp holder is assembling
When need to penetrate into conductor wire in fixing hole, then conductor wire is positioned by conductive cap, assembling process is cumbersome, assembling
Efficiency is still low, is unfavorable for market competition.And existing LEDbulb lamp is generally 120 degree of luminous bulbs, the bulb lamp
It is that LED is mounted in radiator plane, lighting angle is vertical with spreader surface and deploys by shafts axle of vertical plane, hair be present
The problem of angular is small, light irradiation less than radiating plane below place, assemble LED when it is easily that both positive and negative polarity is reversed, easily make
It is low into the non-luminous phenomenons of LED, qualification rate.
