Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electronic component testing, in particular to a testing fixture used for electronic components with soft wires. Background Art
[0002] During the production process, electronic components require circuit testing. This is typically done using an electronic component tester and software. The MPF-2 electronic component's external interface consists of six multi-strand copper flexible wires insulated with Teflon. Product testing requires connecting the wires on the test fixture to the lead ends of the product under test.
[0003] However, this method has the following disadvantages:
[0004] 1. Multiple wires on each product need to be stripped.
[0005] 2. The wire stripping process will inevitably cause multiple strands of wire to break, and a large amount of wire scraps will be generated during the test operation, which will affect product quality.
[0006] 3. Wire shavings also have a great impact on the reliability of the test system.
[0007] 4. Each test requires manual clamping of each wire with a wire clamp, which results in long working hours, low efficiency and poor reliability.
[0008] 5. The wire clamps are also easily damaged during the test process. Utility Model Content
