LED aging tester
Technical field
The invention belongs to LED checkout equipment field, more specifically relate to LED aging tester.
Background technology
In the process of direct insertion LED production and processing, later stage needs the LED lamp bead of whole finished product to carry out normal ageing, accelerated deterioration, light decay etc. and tests, some LED lamp bead sockets are distributed with above current LED aging tester, in order to test LED lamp bead performance, what current lamp pearl socket inside contacted with LED pole pin is all conductive metal pipe, after long-term mounting or dismounting, metal tube can loosen and cause metal tube bad with contacting of pole pin.
Summary of the invention
In order to solve the problem, the invention provides that a kind of structure is simple, contact is good, long service life, safe and reliable LED aging tester.
According to an aspect of the present invention, LED aging tester comprises frame, substrate, first connecting line and socket, substrate is arranged in frame, substrate is provided with some sockets, socket comprises body, socket, contact element and the second connecting line, some contact elements are provided with in described body, socket is arranged on body, socket is just to contact element, contact element comprises some contacts, spring and fixing body, contact surrounds into annular, contact fixed by spring, fixing body is arranged on contact, connecting line connection body, so that realize contacting well with LED lamp bead pole pin, longer service life.
In some embodiments, some contact element one end diameter is greater than other end diameter, so that LED lamp bead pole pin inserts convenient.
In some embodiments, contact element diameter large one rectify to socket so that LED lamp bead pole pin insert convenient.
In some embodiments, spring is through contact, and described spring can make contact surround into annular, so that realize contacting well with LED lamp bead pole pin.
In some embodiments, contact and spring are conductor, so that ensure energising.
In some embodiments, body and substrate are insulator, so that ensure safety.
In some embodiments, the first connecting line is connected or is parallel with some second connecting lines, so that form complete loops.
The beneficial effect of LED aging tester of the present invention is: structure of the present invention is simple, contact is good, long service life, safe and reliable.

Embodiment
Below in conjunction with embodiment, the present invention is further illustrated.
As shown in Figure 1, a kind of LED aging tester of an embodiment of the present invention comprises frame 1, substrate 2, first connecting line 3 and socket 4, and substrate 2 is arranged in frame 1, substrate 2 is provided with some sockets 4.
As shown in Figure 2, socket 4 comprises body 41, socket 42, contact element 43 and the second connecting line 44.Body 41 is insulator, so that ensure to use safety when detecting.Body 41 is provided with multiple socket 42 above, and the quantity of socket 42 is optimum is 4.If socket 42 quantity is too many, having socket 42 to contact generation problem just needs whole socket to change, and is unfavorable for repairing safeguarding.Be provided with contact element 43 immediately below socket 42, contact element 43 directly contacts energising with the pole pin of LED.Second connecting line 44 is fixedly connected with contact element 43, forms complete loop.
As shown in Figure 2, contact element 43 is the tubulose of hollow, and the diameter of one end is greater than the diameter of the other end, and in horn-like, one end that diameter is larger is placed in immediately below socket 42, to insert in contact element 43 with the pole pin realizing LED.
As shown in Figure 3, contact element 43 comprises some contacts 431, spring 432 and fixing body 433.Several contacts 431 surround into hollow tubular, and spring 432 can make contact 431 surround into annular.Spring 432 can be centered around outside contact 431, and optimum is punching in the middle of contact 431, and spring 432 passes contact 431, so that make several contacts surround into annular.What current lamp pearl socket inside contacted with LED pole pin is all conductive metal pipe, general is all metal tube made of copper, after long-term mounting or dismounting, metal tube can loosen and cause metal tube bad with contacting of pole pin, and cannot use, Long-Time Service can be solved by the cooperation between multiple contact 431 and spring 432 and contact bad problem, first enter the larger one end of diameter when LED pole pin inserts contact element 43, be convenient to LED pole pin and insert.By clamp-oning of LED pole pin, spring 432 is upheld, contact 431 is enclosed in LED pole pin surrounding thus solves Long-Time Service and contacts bad technical matters.
Arbitrary contact 431 is fixedly connected with fixing body 433, and optimum adopts welding.Second connecting line 44 is fixedly connected with fixing body 433, forms loop.Contact 431, spring 432 and fixing body 433 are metallic conductor, consider economy, electric conductivity optimum is made of copper.First connecting line 3 is connected or is parallel with the second connecting line 44, so that form complete loops.
Structure of the present invention is simple, contact is good, long service life, safe and reliable.
Above-described is only some embodiments of the present invention, it should be pointed out that for the person of ordinary skill of the art, and under the prerequisite not departing from creation design of the present invention, can also make other distortion and improve, these all belong to protection scope of the present invention.
