Description
Technical field
The utility model relates to a kind of testing tool, relates to the direct measuring type tool in order to the testing circuit plate specifically.
Background technology
The circuit board of computer or other electronic equipment will carry out whole detection to these circuit boards after manufacturing is finished, so that determine the whether short circuit or open circuit of this circuit board.This trace routine is achieved by the direct measuring type tool.This direct measuring type tool is mainly a platform, is convexly equipped with some conducting probes on it, the pin Elastic Contact of electronic component on these tips of probes and the circuit board under test, and the bottom then is electrically connected to a circuit test machine by lead.This circuit test machine can the testing circuit plate circuit conditions.
Along with the progress of science and technology, the area of the circuit board of various electronic equipments reduces gradually, and degree of integration of various circuit improves gradually on it, therefore the very little circuit board of this homalographic is detected and becomes very difficult.Existing a kind of tool that detects at the very little circuit board of area takes tiltedly to survey method, is about to the probe inclination certain angle on the existing combined tester, realizes the detection to circuit board.But existing this tool is obliquely installed owing to probe, therefore must improve the position installation accuracy of probe, for this reason, traditional tool disposes the location-plate more than three layers or three layers, and all need the some probe jacks of Precision Machining on every layer of location-plate, and the position, hole on every laminate is not vertically to align, but tilts to align the extra like this processing cost that increased; Look in the point process very inconvenient in maintenance; Higher and the oblique survey influence of tool aspect ratio in addition can not be adorned the test of all automatic test machines and electric glue.
The utility model content
The purpose of this utility model provides a kind of direct measuring type tool simple, with low cost, that versatility is good of measuring.
The purpose of this utility model is achieved through the following technical solutions: a kind of direct measuring type tool, comprise base, cage plate, offer wire guide on the base, be provided with lead in it, cage plate is positioned at the base top, and it is superimposed mutually with base, also comprise location-plate and upward location-plate down, these location-plates are provided with the probe jack, some probes are located in these probe jacks, and the wire guide of the corresponding base of cage plate is offered some spring eyes, place spring in it, the bottom of probe and spring top compress, and the top reaches the upper surface of location-plate.
Advantage of the present utility model is: measure simple, with low cost, easy to maintenance, versatility is good.
Description of drawings
The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the side view of the utility model direct measuring type tool.
Fig. 2 is the partial sectional view of structure A part shown in Figure 1.
Embodiment
Please refer to Fig. 1 to Fig. 2, this direct measuring type tool comprises from bottom to top the base 10 arranged successively, cage plate 20, location-plate 30 and go up location-plate 40 down, and these bases 10, location- plate 30,40 and cage plate 20 are positioned at the guide pillar 14 on the base 10 and align mutually and fixing by some.
The upper surface of this base 10 is offered some wire guides 12 (with reference to figure 2), is furnished with lead 60 in it, and lead 60 1 ends are connected with a circuit test machine (figure does not show), and the other end is connected with corresponding probe 70 bottoms.
This cage plate 20 is positioned at base 10 tops, and superimposed mutually with base 10, and the wire guide 12 on the cage plate 20 on the corresponding base 10 is offered some spring eyes 22, and spring 24 is vertically placed greater than the aperture of wire guide 12 in the aperture of these spring eyes 22 in the spring eye 22.
As a kind of improvement, of the present utility model going up can be set up the known elastic force cloth of industry (figure does not show) between location-plate 40 and the following location-plate 30, so that the purpose of the probe 70 between the binding location-plate.
This time location-plate 30 is positioned at cage plate 20 tops, and separated by a distance, and location-plate 40 is positioned at location-plate 30 tops down on this, and separated by a distance.Be provided with on these location- plates 30,40 and the corresponding probe jack (not label) of spring eye 22 on the cage plate 20, the Kong Weiwei same coordinate of probe and spring, probe 70 is located in these probe jacks, the bottom of probe 70 and spring 24 tops compress, probe 70 tops reach the upper surface of location-plate 40, and contact with the lower surface of a circuit board 50.
During testing circuit plate 50, probe 70 rely on springs 24 elasticity and with the circuit board Elastic Contact, relend and help the electric circuit inspection machine to realize detecting.
In the utility model technology, because probe and spring all are directly installed in the corresponding hole, not needing increases extra steel pipe, makes the whole cost of tool be minimized; The structural design of this no steel pipe of while, make the aperture of probe jack further to dwindle, thereby make that the diameter of probe is reduced significantly, correspondingly, the density of probe (quantity of unit area internal probe) obviously increases, and therefore needn't take tiltedly to survey method as traditional tool, but the vertical survey method, therefore under the situation that guarantees the probe installation accuracy, can reduce the quantity of location-plate, make whole cost be minimized; Because the increase of probe density makes the utility model technology can be widely used in the circuit board detecting of various sizes and specification, and needn't transform tool.
