Abstract
The utility model discloses a general testing mould for a printed wiring board which comprises a positioning pin and is characterized in that the positioning pin comprises a sleeve; a pin rod with a cone-shaped head is flexibly arranged inside the sleeve and a pin rod return spring is arranged inside the sleeve. When the upper mould and the lower mould of the testing mould are in contraposition to each other, a rapid and accurate positioning is still available and the contraposition speed is improved under the action of the cone-shaped head of the pin rod, even if the pin hole and the positioning pin are of uncoaxiality and a certain deviation. The improvement of the contraposition for the mould can reduce false test points, thereby avoiding testing the PCB board of a false open circuit frequently and repeatedly and improving the efficiency greatly.
Description
Technical field
The utility model belongs to the electronic product production mould, particularly a kind of printed wiring board universal test mould.
Background technology
In general, printed wiring board (PCB) all will carry out testing electrical property in process of production, the universal testing machine equipment that is absolutely necessary.Yet universal machine test PCB must do switching by universal mold during product.When mould is tested, generally be to adopt two irons or stainless steel to carry out mould contraposition up and down as register pin, because the head of positioning pin rod is flat, for make its can with the dowel hole contraposition on another mould, must keep certain clearance between register pin and the pilot hole, therefore, this kind locator meams speed is slow, precision is not high, can produce too much false point when testing highdensity pcb board.
The utility model content
The purpose of this utility model is to provide a kind of accurately contraposition fast, improves the printed wiring board universal test mould of measuring accuracy.
Realize that the technical scheme that the utility model purpose adopts is: printed wiring board universal test mould comprises register pin, and described register pin comprises a sleeve pipe, and the pin rod that head is taper is equipped with in activity in sleeve pipe, is provided with the pin rod retracing spring in the sleeve pipe.
Testing mould of the present utility model owing to change register pin pin rod head into taper, when upper and lower mould contraposition, even if pin-and-hole and register pin disalignment have certain deviation, also can accurately be located under the effect of pin rod conical nose fast, and the raising mould is to bit rate.The mould aligning accuracy improves can reduce the false point of test, thereby does not need the pcb board of the false open circuit of frequent repeated test, and efficient improves greatly; By the taper of register pin pin rod head and the spring of center section, make mould pressing contraposition fast, register pin integral body diminishes simultaneously, is fit to dismounting.
The utility model is described in further detail below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of register pin in the utility model.
Embodiment
See Fig. 1, printed wiring board universal test mould comprises mold A and bed die B, each mould A, B comprise test panel 1, base plate 4 and the dividing plate 3 between test panel 1 and base plate 4, test panel 1, base plate 4 and dividing plate 3 are fixedly supported on the pillar 2, being fixed with head on bed die B limit is the register pin 5 of taper, is provided with on mold and register pin 5 corresponding positioning hole 8.
The structure of register pin 5 is seen Fig. 2, comprises a sleeve pipe 503, and pin rod 501 is equipped with in activity in sleeve pipe 503, and the head of pin rod 501 is taper 504, sleeve pipe in be provided with pin rod retracing spring 502.
During test PCB product 7, probe 6 on the test position distributes on request and passes test panel 1, dividing plate 3 and base plate 4, PCB product 7 is positioned on the 7 test positions, mold A moves downward (or bed die B moves upward) and cooperates with register pin 5 on the bed die B by the pilot hole 8 on it and realize accurate fast accurate contraposition, probe 6 is contacted with test point on PCB product 7 two sides respectively, and probe 6 other ends link to each other with test machine.
