Folding type ICT needle bed fixture

Abstract

The invention discloses a foldable ICT needle bed tool, comprising a body frame, a needle plate fixed on the body frame, probes on the needle plate, and a cover, wherein when the foldable ICT needle bed is in use, the cover is under the body frame, when the cover completely covers the probes, the depth of a contain space of a cover plate frame of the cover is not smaller than the height of the highest element on the needle plate. In storage and transmission, the cover plate frame and the cover plate cover the probes, to avoid oxidizing the probes and dust, impact or compression, to confirm the test accuracy of PCBA and the service life of probes. And when stores a plurality of foldable ICT needle bed tools, the tools can be folded and stored together to save space, without special storage cabinet, to save cost.

Description

technical field [0001] The invention relates to a jig, in particular to a foldable ICT needle bed jig with a reversible cover plate. Background technique [0002] At present, the existing needle bed fixtures are generally composed of a main body. A connector is arranged on the rear side of the main body. Fixed arms are respectively provided on both sides of the bottom of the main body. The fixed arms are convenient for fixing the main body. There is a needle guard at a certain distance from the upper surface, and several probes are arranged on the main body and pass through the needle guard upwards. The arrangement order of the connectors is from bottom to top, from right to left, and the number of the connectors is from Small and big. The existing needle bed fixture has the following defects: 1) The fixture does not contain any dustproof and protective devices, so the probe is always exposed to the air, which is easy to cause the oxidation of the probe, thereby affecting t...

AI Technical Summary

Problems solved by technology

The existing needle bed fixture has the following defects: 1) The fixture does not contain any dustproof and protective devices, so the probe is always exposed to the air, which is easy to cause the oxidation of the probe, thereby affecting the test quality of PCBA; 2) the air There is a lot of dust in the middle, because the probe is exposed, so the dust is easy to accumulate on the probe and affect the test quality of PCBA; 3) Since the probe is exposed, there is no effective protection, so when the fixture is subjected to external impact, the probe The pins are easy to be impacted or squeezed by the outside at the same time, which will cause the structural deformation of the probe, which will affect the test quality of the PCBA in the slightest, and can no longer be used in severe cases; 4) The connector on the main body is also exposed to the air, so the connector The connecting pins of the connectors are also directly in contact with the air, which is easy to form the oxidation of the metal connecting pins, which directly affects the test quality of the PCBA, and the connector has no effective protective structure. When the main body is impacted or squeezed by the outside, the plastic shell of the connector It is experienced that it is broken and deformed due to impact or extrusion, so that the connector cannot detect the PCBA, so the overall fixture can no longer be used for PCBA detection; 5) In addition, because the probe of the existing fixture is directly extended out of the protective needle plate, and the connector is located on the side of the main body. Neither the probe nor the connector can be squeezed or impacted. Occupy a very large area during the process, or manufacture special storage cabinets to store the above-mentioned jigs, and the manufacture of these storage cabinets will not only increase the cost, but also need to occupy a certain amount of storage space when the jigs are taken out for use. Space can not be fully utilized
