Metal material is met to occupy the majority.When the lamp holder of LED is aluminium lamp holder, aluminium lamp holder refers to that the material for constituting lamp holder is main
For aluminium, i.e. lamp holder material both can with the mixing of all aluminium materials or aluminium and other materials, when for mixture,
As long as meeting aluminium material to occupy the majority.
It is understandable to enable above-mentioned purpose of the present utility model, feature and advantage to become apparent, below in conjunction with the accompanying drawings to this
The specific embodiment of utility model is described in detail.
The utility model provides a kind of metallic lamp holder of LED, in the present embodiment only by taking aluminium lamp holder as an example, reference picture 1-
5, include lamp holder body 351, hollow conductive pin 301 and the felt pad 352 of aluminium material；Hollow conductive pin 301 is fixed on felt pad
On 352, felt pad 352 is fixedly connected with one end of lamp holder body 351 (extrudes company to the contact position of lamp holder body and felt pad
Connect).The felt pad 352 has pedestal 354, and one end of the pedestal 354 is provided with the 353a of boss one, felt pad 352 and lamp holder body
351 one end forms a plane after being fixedly connected, the 353a of boss one protrudes from above-mentioned plane.It is provided with the other end of pedestal 354
The 353b of boss two, and for matching the hole 355 of fixation hollow conductive pin 301.The benefit of the 353a structures of boss one is set to exist
In：Improve the mechanical strength of felt pad；Aluminium lamp holder high-voltage resistance capability is greatly improved simultaneously, and then reduces high pressure electric shock risk.
Fig. 1 holder structure is described with reference to Fig. 2-3：
As shown in Fig. 2 being Fig. 1 elevational sectional view.This programme is as shown in Figure 3 to the structure of felt pad 352.
Fig. 3 be Fig. 2 in felt pad 352 enlarged drawing.Felt pad 352 has：Pedestal 354, the two ends of pedestal are set respectively
There is the 353a of the boss one and 353b of boss two, and for matching the hole 355 of fixation hollow conductive pin (not shown).The edge in hole 355
Provided with the position-arresting groove 356 for the hollow conductive pin 301 of stop bit, (such conductive pin is fixed to after felt pad 352, conductive pin embedded hole
355, to increase intermetallic creep age distance).Felt pad 352 is realized with lamp holder body 351 by pedestal 354 and is connected.Boss one
353a protrudes from pedestal 354 and the plane formed is connected with lamp holder body 351.Pedestal 354 can be set to outside circle, pedestal 354
Footpath is slightly less than the internal diameter of lamp holder body 351.Preferably, on round base symmetrical cutaway portion, the arc length of cutaway portion
The about 20%-60% of pedestal circumferential length (substantially put down by the axial connecting line of the remaining line of cut of cutaway portion and two conductive pins
OK.) cutaway portion on pedestal, it is advantageous in that：After pedestal is fixed with lamp holder body, the part cut can be used for stop bit,
Prevent felt pad from being rotated in lamp holder body.In addition, the pedestal 354 of felt pad 352, the 353a of boss one and boss at pedestal two ends
Two 353b are trapezoidal, can play a part of guiding in installation process, can reduce installation difficulty.
As the deformation of above-mentioned felt pad 352, position-arresting groove 356 can also be not provided with the 353b of boss two, it is so hollow to lead
Acusector 301 is fixed on felt pad 352, protrudes from the 353b of boss two, as shown in Figure 5.
Parameter declaration：
In such scheme, felt pad uses the structure design of intermediate lands, and boss bossing is highly at least 1.6mm,
To reach high voltage bearing ability.Felt pad uses high temperature resistant, good toughness and the small material of shrinkage rates, such as PBT plastic.
PBT performance parameter:
1st, heat-resistant aging:Enhanced Undterwriter's Laboratory temperature index melts up to 120~140 DEG C (outdoor long-term ageing is also fine)
Change temperature:225~275 DEG C；
2nd, insulating properties:It is excellent that (moist, high temperature can also keep electric performance stablity, be manufacture electronics, the ideal of electric parts
Material)；Dielectric coefficient：3.0-3.2；Arc resistance：120s；
3rd, shrinkage factor：A little in 48 hours after shaping to shrink 0.05%, the change in size during use is very small, be
High reliability material very excellent in terms of forming stability and dimensional accuracy；
4th, non-reinforcing type grade is tough and rich in flexibility, and anti-fragility ability is strong.
Felt pad can be arranged to different colors the need for meet difference.
In addition, this programme lamp holder, using high pressure resistant structure design (lamp body is needed by 3000V High-Voltage Experimentations), by exhausted
The structure design of edge pad so that (such as hollow conductive pin and lamp holder body) leaves creep age distance between charged metal.Preferably, band
The accumulative at least 3.2mm of creep age distance between electric metal.(as shown in Fig. 2 the creep age distance between charged metal：It is divided into three
Segment length a, b, c；It meets：
a+b+c≥3.2mm。
In addition, when the distance between two charged metals are less than 1mm, the high-tension electricity passed through can puncture air, directly at 2 points
Between creep.
To ensure that felt pad has enough mechanical strengths after being fixedly connected with hollow conductive pin, a length is met, a ＞
1.6 (unit mm).
In order to ensure the dimensional accuracy of plastic components after processing, b ＜ 1.5 (unit mm).
Felt pad uses following size in the embodiment of the present invention：a：2、b：1.1、c：0.5 (unit mm).
The thickness of the lamp holder body of aluminium material is usually 0.2~0.4mm.In the present embodiment, the thickness of lamp holder body is used
0.25mm。
It is the further high voltage bearing ability for improving lamp holder, to the table of hollow conductive pin as the deformation of above-described embodiment
Do insulation processing (as shown in Figure 4) in face.Preferably processing mode is the surface spraying insulated paint or spray ambroin in conductive pin
Powder (such as Fig. 4 301a).The thickness of insulated paint or insulated plastic powder is usually 0.04~0.08mm.Preferably thickness is usually
0.06~0.07mm.In order to ensure electrical contact that hollow conductive pin is good, hollow conductive pin from top head 5mm region not
Make surface insulation processing.Certainly other modes can also be used insulated paint or insulating powder (e.g., electricity is coated with the surface of conductive pin
Plating, vacuum sputtering etc.).
Using the lamp holder of such scheme, due to using aluminium material lamp holder, lamp holder realizes fixed connect with fluorescent tube by PUR
Connect.Lamp holder can omit magnetic conductive metal part and (when lamp holder is connected with fluorescent tube, PUR first is coated on into lamp holder due to using aluminium material
The predetermined region in inner side, then lamp holder be connected to fluorescent tube, lamp holder is placed into predetermined high-frequency heating area, passes through high-frequency heating real
Existing lamp holder is fixedly connected with fluorescent tube).
The announcement and teaching of book according to the above description, the utility model those skilled in the art can also be to above-mentioned reality
The mode of applying is changed and changed.Therefore, the utility model is not limited to embodiment disclosed and described above, right
