Description
Technical field
This utility model relates to high-density connector double needle test manufacture field, particularly relates to a kind of double-deck floating type high-density connector。
Background technology
Currently, when high-density connector uses double needle test, boring often and beat stepped hole on needle plate, probe inserts needle plate, and this needle plate is referred to as load needle plate；It is referred to as probe limiting plate with the plate of the next spacing probe of stepped hole form below load needle plate；Bore with surface and punch the float plate in hole and compressed by stage clip and control lifting, probe in floating plate hole without interfere through, this float plate is referred to as floating support plate；In the way of (or other counter structures) position limiting structure to carry needle plate controls the drift error of floating support plate, there is following defect:
1, consider that, when double needle backshank is thinner (during about 0.1mm), the stepped hole of probe limiting plate is not easily processed, difficult processing, the problems such as detection is difficult；
2, utilizing contour structures spacing, position error is big, and machining accuracy Consideration is more, and operational wear should not clean, and hinders the lifting of floating support plate, time serious, floating support plate can be made to deviate, cause grinding probe, finally cause broken needle；
3, detent mechanism is excessively single, it does not have structure is floated, and causes that test is inaccurate, and time serious, mechanism scraps。
Because above-mentioned defect, the design people, actively in addition research and innovation, to founding a kind of double-deck floating type high-density connector so that it is have more the value in industry。
Utility model content
For solving above-mentioned technical problem, the purpose of this utility model be to provide a kind of can precise positioning, probe long service life, the test high floating type high-density connector of bilayer of yield。
The floating type high-density connector of bilayer of the present utility model, including
-fixing seat: described fixing seat includes the upper mounted plate and the bottom plate that are connected by some back-moving springs, and described bottom plate both sides are vertically connected with guide pillar；
-load needle plate, described load needle plate is fixed on described bottom plate；
-probe limiting plate, described probe limiting plate is arranged on described load needle plate both sides；
-it is arranged on the floating support plate between probe limiting plate described in two, it is connected to stage clip between described load needle plate and described floating support plate。
Further, some floating screws being punctured in described load needle plate it are connected between fixed plate and described bottom plate。
Further, some contour screws corresponding with each described back-moving spring respectively it are also associated with between fixed plate and bottom plate。
By such scheme, the floating type high-density connector of bilayer of the present utility model can precise positioning, be greatly improved the test service life of double needle, in the test process of product, can fundamentally improve yield, reduce the maloperation impact on probe, reduce false failure rate simultaneously。
Described above is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be practiced according to the content of description, below with preferred embodiment of the present utility model and coordinate accompanying drawing describe in detail as after。
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model。
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail。Following example are used for illustrating this utility model, but are not limited to scope of the present utility model。
Referring to Fig. 1, the double-deck floating type high-density connector of one described in this utility model one preferred embodiment, including
-fixing seat: fixing seat includes the upper mounted plate 11 and the bottom plate 12 that are connected by some back-moving springs 13, and bottom plate 12 is vertically connected with guide pillar 14 on both sides；
-load needle plate 20, load needle plate 20 is fixed on bottom plate 12；
-probe limiting plate 30, probe limiting plate 30 is arranged on load needle plate 20 both sides；
-it is arranged on the floating support plate 40 between two probe limiting plates 30, between load needle plate 20 and floating support plate 40, it is connected to stage clip 50。
Visible, fixing seat in this utility model is double-deck floating type structure, arranges two guide pillars 14 on floating type fixing seat, it is ensured that is fixed on the load needle plate 20 on bottom plate 12 under the guiding of two guide pillars 14, is freely lifted, reduces grinding。
For preventing load needle plate 20 in the guiding process of guide pillar 14, because operation unbalance stress causes carrying the problem that needle plate 20 presses deviation 40 times with floating support plate, this utility model is also associated with some contour screws 70 corresponding with each back-moving spring 13 respectively between upper mounted plate 11 with bottom plate 12, concrete, this utility model is provided with four back-moving springs 13 and four contour screws 70, back-moving spring 13 is not only played vertically-guided effect by contour screw 70, the counteracting force of back-moving spring 13 can also be played negative function, simultaneously work as the effect of auxiliary guiding。
The process falling ballast needle plate 20 and floating support plate 40 under upper mounted plate 11 stress is that one-level is floated, it is achieved precise positioning。
Further, this utility model is connected to some floating screws 60 being punctured in load needle plate 20 between upper mounted plate 11 and bottom plate 12。Specifically adding four contour floating screws 60 between load needle plate 20 and upper mounted plate 11 and bottom plate 12, load needle plate 20 can be played floating correcting effect with floating support plate 40 by floating screw 60, to overcome the error between tested materials and parts, improves test yield。
When fixing seat falls pressure under continuing, to make the process that load needle plate 20 contacts with floating support plate 40 be two grades of floatings, eating on needle stroke, while ensureing the depth of parallelism of floating support plate 40 lifting, reducing and eat needle stroke more than 40%, from origin, reduce the probability of broken needle, increase yield。When fixing seat covers certain one stroke in the vertical direction along guide pillar 14, trigger device 80 to be pushed open by load needle plate 20, effect by floating screw 60, now probe limiting plate 30 releases the restriction to floating support plate 40 vertical direction, make load needle plate 20 can float in XY direction with floating support plate 40, it is ensured that the accuracy of test。
This utility model utilizes probe limiting plate 30 and each floating screw 60 floating support plate 40 carries out the spacing of vertical direction, and make load needle plate 20 can float in XY direction with floating support plate 40, utilize two grades of relocation mechanisms, it is ensured that the accuracy of test；Utilize double; two guide pillar 14 to realize accurate guide-localization with contour screw 70, the dispersion force of back-moving spring 13 can be weakened simultaneously, it is to avoid floating support plate 40 deviates, probe abrasion, it is ensured that the service life of probe。
The above is only preferred implementation of the present utility model; it is not limited to this utility model; should be understood that; for those skilled in the art; under the premise without departing from this utility model know-why; can also making some improvement and modification, these improve and modification also should be regarded as protection domain of the present utility model。
