Abstract
The utility model relates to an IC on-line testing connector, which comprises a spring clip. The IC on-line testing connector is characterized in that the lower pin of each half clip is hinged with a base seat; a plurality of spring pieces are inserted onto the base seat; conducting wires are led out from the rear part of each spring piece and are respectively mutually connected with each pin of a plug. The utility model makes each pin of the measured integrated circuit led out once through the plug; the signal of each pin is sent to a testing instrument through a distributor, which make the test of the integrated circuit simple; not only time and manpower are saved, but also the power is enhanced. The utility model has the advantages of higher reliability, simple structure and easy manufacture.
Description
The utility model relates to a kind of integrated circuit on-line testing unitor.
On-line testing is the important ring of electronic equipment in contrived experiment, production debugging and use maintenance process.Present method of testing is that the stylus with instrument goes to contact the measured point, comes reading of data.This method of testing very big inconvenience occurred in the moment that electronic technology develops into current integrated circuit; Because the pin-pitch of integrated circuit is less, generally has only 2.54 millimeters, the close pin of minority is 1.78 millimeters, and is careless slightly during test, will the company's of causing pin.Not only indeterminacy data also can burn out components and parts, and therefore, developing by leaps and bounds of electronic technology proposed challenge to traditional on-line testing mode, and the version that changes existing stylus and probe is imperative.
The purpose of this utility model provides a kind of on-line testing unitor of new structure, and it can overcome existing shortcoming in the prior art.
The purpose of this utility model is achieved in that it comprises a spring clip, it is characterized in that the leftover bits and pieces of per half clip is hinged with a pedestal, is fitted with a plurality of shell fragments on the pedestal, and each shell fragment afterbody all has lead to draw, and each pin with plug links respectively.
The utility model is connected to each pin of tested integrated circuit on the divider by plug once, and one by one the signal on each pin of integrated circuit is delivered on the test instrumentation by the switch of divider.
The utility model makes simple to operateization of on-line testing of integrated circuit, and even pin phenomenon will not appear, not only saved the time, manpower, and improved effect, in addition because shell fragment shape of the present utility model has guaranteed and integrated circuit pin between the pressing of two directions, so reliability is higher, the utility model is simple in structure, is easy to processing.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is described in further detail.
Fig. 1 is the structural representation of a kind of specific embodiment of the present utility model.
Fig. 2 is the side view of Fig. 1.
Fig. 3 is the synoptic diagram of plug of the present utility model.
Fig. 4 be unitor of the present utility model in use, the pin force diagram of integrated circuit.
As seen from the figure, spring clip 1 is formed by 2 half, and spring 2 is housed above, joins with pin-and-hole 3 between the two halves clip, and promptly wherein half has little pin, and second half has aperture, pegs graft mutually.Leftover bits and pieces at per half spring clip all is hinged with pedestal 6, be fitted with a plurality of shell fragments 5 on per half pedestal, shell fragment 5 usefulness deformed spring sheets bend and form, and top has a hangnail 8, after inserting it into, just can not come off out, the tail end 7 of shell fragment be welded with lead 4, and all leads are drawn, be connected to each pin on the plug shown in Figure 39, after plug being inserted into the socket of divider, just can rely on the switch of divider, one by one the signal of each pin be exported.
As shown in Figure 4, because shell fragment has mutually perpendicular two surface of contact, so when using, the pin 11 of integrated circuit 10 is subjected to the power of both direction, i.e. Fx shown in the figure and Fy.12 is printed-wiring board (PWB) among the figure.
Claims (2)
1, a kind of integrated circuit on-line testing unitor, it comprises a spring clip, it is characterized in that the leftover bits and pieces of per half clip is hinged with a pedestal, is fitted with a plurality of shell fragments on the pedestal, and each shell fragment afterbody all has lead to draw, and each pin with plug links respectively.
2, integrated circuit on-line testing unitor according to claim 1 is characterized in that: shell fragment has to be bent by the deformed spring sheet and forms mutually perpendicular two surface of contact.
