Description
Technical Field
The utility model relates to a test needle device especially relates to a small-size two-sided golden finger test needle device.
Background
Global consumer electronics products are undergoing tremendous changes in product definition, appearance design, and functional applications, etc., with various types and functions, but their corresponding types of connection interfaces are standardized.
Taking apple products as an example, the apple products serve as a leading sheep in the industry, and charging and communication interfaces of all consumer products are of uniform models. How to realize the rapid, accurate and stable test of the joint is a difficult problem to be overcome in the field
But the current suppliers who test this style of splice have common challenges:
1. two probes must be implanted per golden finger to complete the test.
2. The golden fingers on the front side and the back side are symmetrical, and the probes must contact the golden fingers at the same time.
3. When designing a corresponding pin carrier plate module, the staggered positions of the front and back probes need to be considered, and the probes are prevented from being damaged under the condition that the connectors are not put in.
4. The rated current of the probe needs to meet more than 2A, but if the rated current of the probe in the testing industry reaches 2A, the diameter of the probe needs to be at least phi 0.5 mm.
