Through this mode, on the lamp socket that both end power supplying LED straight tube fluorescent tube is mounted to correspondence during, first, the One conductive pin 12 will be constantly subjected to the elastic-restoring force effect of the first compression spring 16 so that the first conductive pin 12 is being compressed During will not block and die from first sleeve 11；As long as on the second the first the most fully-inserted to corresponding lamp sockets of conductive pin 12 During external power receptacle (not shown), the first conductive pin 12 the most necessarily will not contact with each other with the second conductive pin 15, that is keeps The off-position being electrically not turned on, it is ensured that LED straight tube fluorescent tube necessarily will not produce during being mounted on the lamp socket of correspondence The situation of error shock.In one embodiment, the end 122 of the first conductive pin 12 can by compression total amount between 1.2 millimeters to 1.7 milli Between meter, preferably 1.5 millimeters, the first conductive pin 12 often compresses one millimeter of suffered elastic force and functions as 140gw extremely 190gw。

Therefore, the lamp holder conductive pin group for both end power supplying LED straight tube fluorescent tube that each embodiment of this utility model is proposed Part 1 can allow the LED straight lamp product of both end power supplying not increase the manufacturing cost of LED straight tube fluorescent tube and do not increasing driving In the case of power volume, by international safety standard IEC62776 and EN62776, reach required safety requirement.

The foregoing is only this utility model preferred embodiment, be not limited to this utility model and apply for a patent right； Above description, should understand for those of ordinary skill in the art and implement, therefore other is without departing from this utility model The equivalence completed under disclosed spirit changes or modifies, and is intended to be limited solely by claim.
