Abstract:
1. A positioning device, used for testing a resistance of a camera module, comprising: a positioning mechanism comprising a receiving member, a positioning member received in the receiving member, and a cover rotatable connected to the receiving member, the receiving member defining two sliding grooves, the positioning member defining a positioning groove for receiving the camera module, and the two sliding grooves located at opposite sides of the positioning groove and communicating with the positioning groove; a contacting mechanism located in the positioning mechanism, comprising a first contacting module and a second contacting module, each of the first contacting module and the second contacting module comprising a sliding block slidably received in one corresponding sliding groove and a first contacting member fastened to the sliding block adjacent to the positioning groove; and a connecting mechanism located adjacent to an end of the positioning mechanism, comprising two second connecting members, and each of the two second connecting members electrically connected to one corresponding first contacting member, wherein the cover defines two driving grooves corresponding to the two sliding grooves, a width of each of the two driving grooves gradually becomes smaller along a direction away from the receiving member to form a driving surface, the sliding block comprises a slanted surface corresponding to the driving surface, when the cover is rotated to cover the receiving member, the driving surface resists with the slanted surface to drive the sliding block to move towards the positioning groove until the first contacting member contacts one testing point of the camera module.
