Abstract
The invention provides a clamp for PCB detection. The clamp comprises a positioning seat and a plurality of clamping pieces which are made of a ferromagnetic material, wherein the positioning seat comprises an upper magnetic board, a magnet vane and a lower magnetic board which are arranged from top to bottom in parallel; the periphery of the positioning seat is fully sealed by a metal shell; the upper magnetic board, the magnet vane and the lower magnetic board are arranged in the same size; a plurality of first hole sites are formed in the upper magnetic board, first magnetic parts are arranged in the first hole sites; a plurality of second hole sites are formed in the lower magnetic board, and second magnetic parts are arranged in the second hole sites; each clamping piece comprises an adsorption seat and a clamping part which are integrally formed; and a plurality of grooves are formed in each clamping part and are used for accommodating circuit boards. According to the clamp, due to the arrangement of the clamping pieces and the upper magnetic board, the clamping pieces can randomly move on the upper magnetic board with a large application range by magnetic attraction; and, due to the arrangement of the lower magnetic board, the clamp can be fixed and removed by means of magnetizing and demagnetizing. The clamp is convenient to assemble and disassemble, and has a good fastening effect and a simple structure.
