Description

Technical Field

[0001] The utility model relates to the technical field of test fixtures, in particular to a mA-level current product test fixture. Background Art

[0002] In our daily life, there are many reasons why jigs are used. They are produced because of business needs. There are many types of jigs that are customized, some of which are designed to improve productivity, repeat specific actions, or make work more precise. Because the design of jigs is basically based on logic, similar jigs may be produced separately because they are used at different times and places.

[0003] After searching, the patent with application number 201620488816.8 is a mA-level current product test fixture, including an insulating fixture, a metal block and a wire. Two metal blocks are fixed on the insulating fixture at intervals, and the two metal blocks are respectively in contact with the positive and negative electrodes of the PD to be tested, and the metal blocks are fixedly connected with wires. Compared with the existing fixture, the patent has the following advantages: the traditional probe is not used to test the dark current of the PD, but the PD is directly fixed on the fixture, and the positive and negative electrodes of the PD are powered by two metal blocks at the same time, and the power supply and the ammeter are connected by the wires connected to the two metal blocks. The utility model has the characteristics of low cost, easy operation, can reduce product cost, and greatly improve production efficiency. However, when the patent is used, it can only test the same current product at the same time. After completing the test work of the previous current product, it can be removed, and then another current product is placed for repeated testing. This will require the staff to spend a lot of time and energy, and cause the production capacity to drop greatly, thereby reducing the practicality of the product. Utility Model Content
