Specific embodiment

In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain The utility model is not used to limit the utility model.

In the present invention it should be noted that term " on " "lower" " left side " " right side " "vertical" "horizontal" "inner" "outside" etc. It is to be based on the orientation or positional relationship shown in the drawings, it is only for convenient for description the utility model and simplify description, without It is that the device of indication or suggestion the utility model or element must have a particular orientation, therefore should not be understood as practical new to this The limitation of type.

Embodiment one

Refering to what is shown in Fig. 1, the utility model discloses a kind of PCBA test equipment with protective device, including testboard 1, Testing jig 2, test fixture 3, power supply, test switch 4, tester 5, test board 6 and driving assembly 7, testing jig 2 are set to testboard 1 side, test fixture 3 and tester 5 are set on testboard 1, and test fixture 3 is for placing PCBA to be measured, power supply, test switch 4, tester 5 and PCBA to be measured are successively electrically connected.

Cooperate shown in Fig. 1 and Fig. 2, delay normal open switch 8 is in series between tester 5 and test board 6, be delayed normal open switch 8 both ends are parallel with protection circuit, and protection circuit includes the loudspeaker 91 being sequentially connected in series, band switch 92 and test light bulb 93, When the PCBA short circuit of test, the sending of loudspeaker 91 prompt tone, test light bulb 93 are shinny, and band switch 92 is used for according to difference The parameter selection of PCBA is suitble to test the power gear of light bulb 93.

Cooperating shown in Fig. 1 and Fig. 3, driving assembly 7 makes it contact or separate with PCBA to be measured for going up and down test board 6, It includes mounting base 71, handle 72, moving part 73 and drive rod 74, and mounting base 71 is fixedly arranged on testing jig 2 comprising vertical The end of upper mounting seat 711 and lower mounting seat 712 on direction, lower mounting seat 712 is equipped with pilot hole (not shown), handle 72 include grip part 721 and the interconnecting piece 722 being bent to form by 721 one end of grip part, and the lower end of interconnecting piece 722 is articulated with peace The end of seat 711 is filled, the upper end of interconnecting piece 722 and one end of moving part 73 are hinged, and the other end of moving part 73 is hinged with drive Lever 74, drive rod 74 pass through pilot hole after with 6 Joint of test board.
