Detailed Description

The following detailed description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings, will make the advantages and features of the utility model easier to understand by those skilled in the art, and thus will clearly and clearly define the scope of the utility model.

Referring to fig. 1 to 4, the spring probe assembly mistake proofing device in this embodiment includes an upper cover plate 1, an assembly plate 2, and an ejector plate 3, which are sequentially disposed from top to bottom; the upper cover plate 1 and the assembly plate 2 are respectively provided with a plurality of assembly sieve holes I5 and assembly sieve holes II 11 for placing the needle tubes 6, and when the spring probes are assembled, the needle tubes 6 are firstly placed into the assembly sieve holes I5 and vertically fall into the assembly sieve holes II 11; the needle tube 6 is placed in the needle tube 6, the needle 7 is placed in the assembly sieve hole I5 and vertically enters the needle tube 6 in the assembly sieve hole II 11, the needle tube 6 cannot fall off the assembly plate 2 due to the fact that the assembly sieve hole III 12 with the diameter smaller than that of the needle tube 6 is arranged at the bottom, the needle 7 with the diameter larger than that of the needle tube 7 is exposed out of the bottom of the assembly plate 2 due to the fact that the diameter of the needle tube is smaller, and the centers of the assembly sieve hole I5, the assembly sieve hole II 11 and the assembly sieve hole III 12 are located on the same straight line, and therefore the phenomenon of dislocation cannot occur when the needle tube 6 is placed and assembled in sequence; the upper end face of the ejector plate 3 is provided with a boss 13, when the ejector plate 3 moves upwards, the boss 13 moves upwards to push the needle 7 upwards, and the spring 8 arranged on the needle 7 moves upwards to eject the needle tube 6.

The lower end face of the assembling plate 2 is provided with a yielding groove 10, the yielding groove 10 is identical to the boss 13 in shape and matched with the boss 13 in size, and the boss 13 is yielded through the yielding groove 10, so that the boss 13 can eject the needle 7 out of the needle tube 6.

The upper end face of the assembling plate 2 is provided with a plurality of positioning pins 4, and the upper cover plate 1 is provided with positioning holes 9 corresponding to the positioning pins 4 in position, so that dislocation can not occur during assembling.
