Abstract
The utility model discloses a flexible needle testing device of a high-density connector. The flexible needle testing device is characterized by comprising a supporting plate, supporting columns and flexible probe limiting plates, wherein the supporting plate is provided with a floating needle plate; the floating needle plate is provided with a pre-pressing plate; and the floating needle plate is connected with a flexible probe. Compared with the prior art, the flexible needle testing device has the advantages that in a testing and utilizing process of a product, the yield is basically improved, influences on the probe by incorrect operation are reduced, and the incorrect measurement rate is reduced simultaneously; and meanwhile, the whole replacing time of a module is short, the efficiency is high and the maintenance is convenient.
Description
Technical field
The utility model relates to a kind of high-density connector flexible needle proving installation.
Background technology
Current, during the high-density connector test, often adopt on different needle plates, to bore and beat stepped hole, probe guarantees the fixed position of probe, simultaneously by the machining precision of needle plate in the middle of different needle plates, the probe that uses is the easily broken probes such as double-ended needle substantially, easily in test process, the situation of broken needle or test NG occurs, and therefore there is following some problem in product in the past:
1, spacing between needle plate of probe is that hole depth by needle plate guarantees, difficulty of processing increases so on the one hand, on the other hand, easily causes broken needle and be difficult for assembling when assembling;
2, adopt the inflexibility probe test, if the probe ride out is long on the one hand, so very easily easily cause broken needle in test process; On the other hand, probe exposes short, is difficult for broken needle, but can exist the test fraction defective higher, and the situation of test occurs repeatedly;
3, the high-density connector test does not have modularity, is difficult for assembling and changes, and in the maintaining process in later stage, can not change and maintenance by modularity.
The utility model content
The utility model provides a kind of high-density connector flexible needle proving installation in order to solve the above-mentioned deficiency of prior art.
Above-mentioned purpose of the present utility model realizes by following technical scheme: a kind of high-density connector flexible needle proving installation, it is characterized in that: comprise back up pad, support column, flexible stylet limiting plate, described back up pad is provided with unsteady needle plate, the needle plate that floats is provided with prefabricating plate, and described unsteady needle plate connects flexible stylet.
Described unsteady needle plate top is prefabricating plate, and after high-density connector placed, external force can be directly not stressed to the needle plate that floats, but power directly acts on prefabricating plate, by the lower surface of prefabricating plate, power is delivered on the needle plate that floats uniformly, guarantee the vertical depression of power.
The utility model advantage compared with prior art is: in the test use procedure of product, fundamentally improve yield, reduce maloperation to the impact of probe, reduce simultaneously false failure rate; Simultaneously, guarantee that the integral replacing time of module is short, efficient is high, and is easy to maintenance.
Description of drawings
Fig. 1 is the structural representation of the utility model original state.
Structural representation when Fig. 2 is the utility model closure.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in Figure 1 and Figure 2, a kind of high-density connector flexible needle proving installation, it is characterized in that: comprise back up pad 1, support column 2, flexible stylet limiting plate 3 and flexible stylet limiting plate 4, described back up pad 1 is provided with the needle plate 5 that floats, the needle plate 5 that floats is provided with prefabricating plate 6, and described unsteady needle plate 5 connects flexible stylet 7.
Described unsteady needle plate 5 tops are prefabricating plates 6, and after high-density connector placed, external force can be directly not stressed to the needle plate that floats, but power directly acts on prefabricating plate 6, by the lower surface of prefabricating plate 6, power is delivered on the needle plate 5 that floats uniformly, guarantee the vertical depression of power.
During assembling, flexible stylet 7 is caught from back up pad 1 bottom, and 7 times Surface of Spheres of flexible stylet are equipped with needle guard, are connected to the connection wire on the needle guard, are welded direct to pcb board; Round end is realized spacing by the flexible stylet limiting plate under the flexible stylet.
Described flexible stylet motion process: when flexible stylet 7 was pressed down by external force, the flexible stylet head can be delivered to external force the flexible stylet middle part, the stressed bending of middle part meeting, and when the external force disappearance, flexible stylet 7 is recovered former states.
Later maintenance: going wrong or during broken needle, only need to be with 4 dismountings of flexible stylet limiting plate, change and get final product, realize that modularity is installed and replacing.
But above-mentioned embodiment is exemplary, is to be the restriction that this patent is comprised scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses do anyly be equal to change or modify, all fall into the scope that this patent comprises.
