Problems solved by technology

[0002] Surface mount two-pole components involve resistors, capacitors, diodes and other components, and the package sizes are various. For each package size, it is necessary to make corresponding test fixtures. Making a large number of fixtures consumes a lot of money, resulting in production Increased cost; when testing a new size component, the test fixture must be customized according to the size of the component, resulting in a longer test cycle; when testing, it is necessary to frequently place and remove the tested component in the test fixture, resulting in production efficiency not tall

Abstract

The invention discloses a universal test fixture for surface-mounted two-pole components, which includes a front and rear sliding positioning slider, an elastic test probe module and a pull-out base plate. The screw and nut set at the bottom drive the two sliding bodies to move towards each other, and there is a movable pull-out bottom plate near the bottom. The test probe module includes elastically expandable left test probes and right test probes placed facing each other. In the present invention, the device under test is placed in a variable placement slot, and the rapid replacement and testing of the device under test can be realized through the fastening of the elastic test probe and the detachment of the drawing bottom plate, and the variable two sliders And the elastic pressure rod can realize the test of different specifications of the device under test, greatly improve the test efficiency and test accuracy, and also has the characteristics of simple structure, convenient operation and use, and low price.

Description

technical field [0001] The invention belongs to the technical field of electronic component testing devices, and relates to a universal testing fixture for surface-mounted two-pole components.
