Abstract
The utility model discloses a kind of staight needle formula environmental protection tool, comprise base, support column and insulcrete and needle plate, vertically run through in described needle plate and a straight probe is set, described straight probe top is provided with flattening portion, and flattening portion is positioned at middle needle plate, is provided with backing plate between described insulcrete and end needle plate, and straight probe lower end is connected with the upper end of the spring be arranged in backing plate, the lower end of described spring connects enameled wire, and described enameled wire through insulcrete, and is connected with the ox horn joint be arranged on base.The design of this staight needle formula environmental protection tool is rationally more scientific, and spent material is less, more environmental protection and easier, relatively and combined tester, straight probe is without slope and effectively can control straight probe and go out pin height, vertically stressed, straight probe is not flexible, and maintenance rate is the end very, and stability is better.
Description
Technical field
The utility model relates to pcb board field tests, specifically a kind of staight needle formula environmental protection tool.
Background technology
For printed circuit board (PCB), to be a kind of with pcb board be its measurement jig often adopted that model designs, for a kind of unit clamp of electrical property on off test, there is dividing of one side tool, two-sided tool, tool has dials, and the probe on dials directly determines stability and the efficiency of electric performance test; In actual production, pcb board mostly is batch micro operations, batch testing, needs to ensure that probe is in good state all the time on dials, once probe breaks down, especially intermittent defect, test by mistake will be caused and cause quality accident, and often needing large batch of products reclaiming to retest.For the open-short circuit tool of traditional structure, its probe and sleeve are all located on needle plate, manually each sleeve tail end electric wire is wound to ox horn joint, and a set of tool often must be wound around more than 100, so a large amount of winding actions must expend extremely long man-hour, relative manufacturing cost is inevitable quite high, and excessive and usually discarded by whole needle plate owing to changing probe difficulty.At present, market circulation based on combined tester, but by the impact of combined tester density and slope, this tool maintenance rate is high, and test yield is relatively low.
Utility model content
It is not flexible that the purpose of this utility model is to provide a kind of probe, and maintenance rate is the end very, the staight needle formula environmental protection tool that stability is better, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of staight needle formula environmental protection tool, comprise base, support column and insulcrete and needle plate, vertically run through in described needle plate and a straight probe is set, described straight probe top is provided with flattening portion, and flattening portion is positioned at middle needle plate, is provided with backing plate between described insulcrete and end needle plate, and straight probe lower end is connected with the upper end of the spring be arranged in backing plate, the lower end of described spring connects enameled wire, and described enameled wire through insulcrete, and is connected with the ox horn joint be arranged on base.
As further program of the utility model: described needle plate comprises end needle plate, middle needle plate and ejector retainner plate, between adjacent middle needle plate, between middle needle plate and end needle plate, and be equipped with copper web member between middle needle plate and ejector retainner plate.
As further program of the utility model: described middle needle plate thickness is greater than the thickness of end needle plate and ejector retainner plate.
As further program of the utility model: the long 16-20mm of described straight probe, and needle plate surface 0.3-0.6mm is stretched out at two ends.
Compared with prior art, the beneficial effects of the utility model are:
The design of this staight needle formula environmental protection tool is rationally more scientific, and spent material is less, more environmental protection and easier, relatively and combined tester, straight probe is without slope and effectively can control straight probe and go out pin height, vertically stressed, straight probe is not flexible, and maintenance rate is the end very, and stability is better.
Accompanying drawing explanation
Fig. 1 is the structural representation of staight needle formula environmental protection tool;
Needle plate, 9-ejector retainner plate, the straight probe of 10-, 11-flattening portion, 12-spring in the middle of needle plate, the copper web member of 7-, 8-at the bottom of 1-base, 2-support column, 3-enameled wire, 4-insulcrete, 5-backing plate, 6-.
Embodiment
Be described in more detail below in conjunction with the technical scheme of embodiment to this patent.
Refer to Fig. 1, a kind of staight needle formula environmental protection tool, comprise base 1, support column 2 and insulcrete 4 and needle plate, described needle plate comprises end needle plate 6, middle needle plate 8 and ejector retainner plate 9, and middle needle plate 8 thickness is greater than the thickness of end needle plate 6 and ejector retainner plate 9, between adjacent middle needle plate 8, between middle needle plate 8 and end needle plate 6, and be equipped with copper web member 7 between middle needle plate 8 and ejector retainner plate 9, vertically run through in described needle plate and a straight probe 10 is set, the long 16-20mm of described straight probe 10, and needle plate surface 0.3-0.6mm is stretched out at two ends, described straight probe 10 top is provided with flattening portion 11, and flattening portion 11 is positioned at middle needle plate 8, and then straight probe 10 height can be controlled, and make straight probe 10 to fall pin, backing plate 5 is provided with between described insulcrete 4 and end needle plate 6, and straight probe 10 lower end is connected with the upper end of the spring 12 be arranged in backing plate 5, the lower end of described spring 12 connects enameled wire 3, described enameled wire 3 is through insulcrete 4, and connect with the ox horn joint be arranged on base 1 (being prior art, not shown).
The design of this staight needle formula environmental protection tool is rationally more scientific, and spent material is less, more environmental protection and easier, relatively and combined tester, straight probe 10 is without slope and effectively can control straight probe 10 and go out pin height, vertically stressed, straight probe 10 is not flexible, and maintenance rate is the end very, and stability is better.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art possesses, can also makes a variety of changes under the prerequisite not departing from this patent aim.
