Stitching testing structure of ZIF (zero insertion force) connector

Abstract

The invention discloses a stitching testing structure of a ZIF (zero insertion force) connector. The stitching testing structure is simple in structure, high in testing efficiency and low in cost, and able to meet requirement of product test automation. The stitching testing structure comprises a PCB (printed circuit board) board (1), a needle block (2), a needle cover (3), at least two springs (4) and a needle block fixing base (5); several probes (6) are fixedly arranged on the needle block (2), and needle holes (3) with the consistent number as the probes for making the probes cross through are arranged on the needle cover; the lower ends of the springs are fixed on the needle block, and upper ends are propped on the lower side face of the needle cover; a lug boss (32) is further arranged on the needle cover, and a blocking stage propped and closely matched with the lug boss (32) is arranged on the needle block fixing base; the PCB board and the needle block are fixedly connected with the needle block fixing base; several probes are arranged on the needle block in a staggering manner; position of the probes is corresponding to the wave peak of a PIN foot on the ZIF connector to be tested. The stitching testing structure of the ZIF connector can be applied to the field of the test device.

Description

technical field [0001] The invention relates to the field of testing equipment, in particular to a needle-down testing structure for a ZIF connector. Background technique [0002] At present, due to the small width of the PIN pin of the ZIF connector, usually only 0.08mm in width, and the distance between the PIN pins is also very small, usually 0.175mm, it is very difficult to use the needle test method. The main method for testing ZIF connectors with existing fixtures is to use manual plugging and wiring for testing, but the testing method for plugging and wiring has the following disadvantages: [0003] 1. The loss rate of the cable is very high, and the cable needs to be replaced frequently, resulting in an increase in cost; [0004] 2. The work efficiency is extremely low: because the cable insertion is done manually, it is time-consuming and labor-intensive, and if the cable is not inserted in place, it will affect the test pass rate; [0005] 3. It cannot meet the r...
