Description
Technical field
The utility model relates to a kind of circuit board testing jig, belongs to the circuit board testing technical field.
Background technology
Circuit board is one of topmost parts in the general electronic products, and it is used for carrying various electronic original parts, such as electric capacity, inductance, resistance, diode and connector slot etc., and in order to be connected with specific device, module formation.
In the process of producing printed circuit board (PCB); Need test printed circuit board (PCB); Conventional test methods is connected to peripherals through the connecting line on the measurement jig then for circuit board under test is arranged on the measurement jig, thereby realizes the test to operativeness of printed circuit boards.But traditional testing tool is crosstalked between each connecting line owing to need more connecting line easily each other, thereby can influence the stability of test, in addition, because connecting line is more, also can make the measurement jig volume big, heavy.
The utility model content
Be to solve the deficiency of prior art, the purpose of the utility model is to provide that a kind of test performance is stable, little, the lightweight circuit board testing jig of volume.
For achieving the above object, the utility model is to realize through following technical scheme:
A kind of circuit board testing jig; Comprise base, needle plate, support plate and probe, the edge of said base, needle plate and support plate is provided with through hole, and passes through hole by said probe and connect successively; Said base is provided with a plurality of slots, and said slot is connected with base through lead; On the said needle plate osculating element is set, on the said support plate draw-in groove is set, the position of said osculating element and draw-in groove is corresponding each other.
Firm in order to guarantee the circuit board installation on the support plate, the draw-in groove both sides of said support plate are provided with buckle.
For circuit board is switched on when needs are tested, cut off the power supply in the time of need not testing, thereby, avoid circuit board in the process of test or dismounting, to damage, said base comprises shift knob.
For whether affirmation circuit board that can be clear is in state to be tested, said base comprises pilot lamp.
The beneficial effect of the utility model is: the described circuit board testing jig of the utility model; Use probe to connect base, needle plate and support plate; And at base position a plurality of slots are set, the coupling external unit has reduced the use of connecting line; Avoid crosstalking each other between the connecting line, guaranteed the stability of test; And use the design of buckle, and guaranteed that circuit board installs firmly, can landing; Also used switch simultaneously, when not testing, can cut off the electricity supply, can effectively avoid circuit board to be burnt the damage that to avoid circuit board in unloading process, to cause because of long-time power supply; In addition, the utility model has also been installed pilot lamp, and the duty of indicating circuit plate makes duty clear; In addition, the utility model body less, in light weight, be convenient to the operation, be easy to apply.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done concrete introduction.
Fig. 1 is the structural representation of the utility model one embodiment.
As shown in Figure 1: a kind of circuit board testing jig comprises base 1, needle plate 2, support plate 3 and probe 12.
Said base 1, needle plate 2 and support plate 3 are placed successively from bottom to top, and its edge is provided with through hole 8.In the present embodiment, said base 1, needle plate 2 and support plate 3 are rectangle, and through hole 8 is arranged at the place, four angles of rectangle.Probe 12 passes through hole 8 base 1, needle plate 2 and support plate 3 is connected successively.
Said base 1 is provided with a plurality of slots 6, and said slot 6 is connected with base 1 through lead 7; Also be provided with shift knob 9 on the said base 1, circuit board is switched on when needs are tested, outage in the time of need not testing, thereby, avoid circuit board in the process of test or dismounting, to damage.In addition, also be provided with pilot lamp on the said base 1, in the present embodiment, pilot lamp is divided into two, is respectively red light 101 and green light 102, and when circuit board was in test mode, red light 101 lighted, and when circuit board was in non-test mode, green light 102 lighted.
On the said needle plate 2 osculating element 13 is set, on the said support plate 3 draw-in groove 5 is set, the position of said osculating element 13 and draw-in groove 5 is corresponding each other.Simultaneously, draw-in groove 5 both sides of said support plate 3 are provided with buckle 11, guarantee that the installation of circuit board is firm.
When said circuit board testing jig is worked, open buckle 11, circuit board under test is installed in the draw-in groove 5, buckle well buckle 11.External equipment is connected slot 6, start external equipment.Press shift knob 9, start test, this moment, red light 101 lighted, and after test finishes, pressed shift knob 9, closed test, and test green light 102 lights, and opens buckle 11, takes out circuit board under test, accomplished once test.
The foregoing description does not limit the utility model in any form, and all employings are equal to the technical scheme that mode obtained of replacement or equivalent transformation, all drop in the protection domain of the utility model.
