Abstract
The invention provides a testing device for a PCB (printed circuit board) with multiple stamp holes, which comprises an upper testing frame substrate, a lower testing frame substrate, a bracket and a plurality of spring pins. The bracket is connected with the upper testing frame substrate and the lower testing frame substrate, and the spring pins are arranged between the two substrates in a trapezoidal shape with the upper part larger than the lower part. The testing device for the PCB with multiple stamp holes provided by the invention has the beneficial effects that: the cost of the spring pins is less than the cost of thin ejector pins; the contact area is large, and poor contact resulting from small errors can be avoided; and the device can be maintained easily, one end of the device is fixed, the other end of the device is movable, the device can be replaced conveniently, and the height of the device can be adjusted freely.
Description
Technical field
The present invention relates to a kind of proving installation, relate in particular to the pcb board proving installation.
Background technology
Along with development of science and technology; The function of chip from strength to strength; Peripheral circuit is along with also increasing; When these functions all are integrated on the plate as a module and external communication, can pass through connected modes such as socket, contact pin, the height that concerning the relatively stricter machine of space requirement, can only reduce spacing and the socket of pin waits and meets the demands, and rosin joint or shock resistance are bad but this connects causes loose contact etc. to cause certain hidden danger to machine; The welding manner of use stamp hole can solve the problem of above existence, and reliability is better than higher anti-seismic performance; But because the spacing between stamp hole is overstocked; To the test of veneer function difficulty relatively, the testing jig that provides in the market all is the mode of the thimble that adopts, and thimble is thin, cost an arm and a leg and disconnected easily, bad maintenance; Practicality is not high, is unfavorable for producing in batches test.
Summary of the invention
In order to solve the problem of test; Thimble is replaced with spring needle, and pin also makes vertical mode into by original parallel top with the way of contact of pcb board on stamp hole, and testing jig is made up of 2 substrates; Spring needle is positioned between 2 substrates; Adopt trapezoidal up big and down small mode, there is loose slot upper end fixedly lower end, and can guarantee picking and placeing and contacting of pcb board by the height that screw is adjusted between substrate voluntarily.
A kind of many stamp holes pcb board proving installation; It comprises testing jig upper substrate, testing jig infrabasal plate, connects the support and the spring needle of testing jig upper substrate and testing jig infrabasal plate; Said spring needle is arranged between two substrates, and set-up mode is trapezoidal up big and down small form.
As further improvement of the present invention, said support is adjustable for height support.
As further improvement of the present invention, said support is a screw.
As further improvement of the present invention, the corresponding spring needle of testing jig upper substrate top is provided with breach.
As further improvement of the present invention, the spring needle upper end is fixed on the testing jig upper substrate, and the spring needle lower end is arranged in the loose slot of testing jig infrabasal plate.
As further improvement of the present invention, also comprise the cabling circular hole, it is arranged on the said testing jig infrabasal plate.The cabling circular hole makes things convenient for the cabling of connecting line.
As further improvement of the present invention, also comprise instrument connection, it is arranged on the said testing jig infrabasal plate.Instrument connection widens the distance between former test point, smooth discharging.
The beneficial effect of many stamp holes pcb board proving installation of the present invention is: adopt spring needle low-cost more than tiny thimble; Surface of contact is bigger, needn't cause loose contact because of the deviation of a little; Safeguard that easily the fixing end of an end is movable, it is convenient to change, and also can freely adjust height.
