Description

Technical Field

[0001] The utility model relates to the technical field related to mobile phone camera testing, in particular to a novel spring pin. Background Art

[0002] A spring pin is a precision connector used in electronic products such as mobile phones and is widely used in semiconductor devices for connection. A spring pin is a spring-loaded probe composed of three basic components: a needle shaft, a spring, and a needle tube. This is then pre-stressed using a precision riveting instrument. It contains a precise spring structure. The surface coating of a spring pin is generally gold-plated to enhance its corrosion resistance, mechanical properties, and electrical performance. Needle tips can be sharp, gripping, round, or knife-shaped. Spring pins are commonly used for precision connections in electronic products such as mobile phones, portable electronic devices, communications, automobiles, medical devices, and aerospace, improving the corrosion resistance, stability, and durability of these connectors. Because a spring pin is a very delicate probe, its use in precision connectors can reduce the weight and size of the connector, making it more refined and aesthetically pleasing.

[0003] At present, the retest rate of old spring pins is high, especially when the tolerance control of product test position is relatively large. In addition, the top diameter of the spring pin is 0.075mm, which is easy to break and needs to be replaced frequently, wasting manpower and material resources. Utility Model Content

[0022] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0023] Example: Figure 1 and Figure 2As shown, the utility model provides a new type of spring needle, including a spring needle body 1, a first end of the spring needle body 1 is provided with a gripping head test end 2, and an end of the gripping head test end 2 away from the spring needle body 1 is provided with multiple test gripping heads 3. By increasing the diameter of the spring needle test end and the number of test gripping heads, the retest rate is reduced and the probability of the spring needle test end breaking is reduced, thereby avoiding the need for frequent replacement and waste of manpower and material resources.

[0024] There are at least six test grippers 3, which can reduce the retest rate and the probability of the spring pin breaking during the test.

[0025] The number of the test grippers 3 is 6-8, which can reduce the retest rate.
