Description

Technical Field

[0001] This utility model relates to the field of spring pin technology, specifically a novel stamped and assembled spring pin. Background Technology

[0002] A spring pin is a type of spring-loaded pin that has compressible elasticity and is commonly used as a connector for transmitting current and signals. In integrated circuit testing, spring pins are core components that connect chips / wafers to test equipment for signal transmission, playing a crucial role in the quality control of semiconductor products.

[0003] Existing technologies, such as the utility model of a stamped structure for assembling a miniature spring probe (authorization number CN219552526U), can limit the abnormal detachment of the needle tip and tail. This shortens the assembly time and increases the tolerance window during the assembly process, thereby improving assembly efficiency.

[0004] Currently, there is a lack of a spring pin that facilitates assembly, allowing the two ends of the spring pin to compress and move towards the middle, thereby contacting the PCB and the chip, resulting in better contact, wider applicability, and longer service life. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a new type of stamped assembly spring pin, which facilitates assembly and allows the two ends of the spring pin to be compressed and moved towards the middle, thereby contacting the PCB and the chip, resulting in better contact, more applicable scenarios, and improved service life.

[0006] This utility model achieves its purpose through the following technical solution:

[0007] A novel stamped spring pin assembly is characterized by comprising: an upper contact end, a lower contact end, and an exposed spring; the upper contact end includes an upper contact component and a connecting component, and the lower contact end includes a lower contact component and the connecting component; the two connecting components are arranged in an alternating manner; the exposed spring connects the two connecting components. The upper contact end, lower contact end, and exposed spring are interference-fitted to achieve connection, assembling into a finished spring pin. The upper and lower contact ends can be compressed and moved towards the middle to contact the PCB and chip for testing.

[0008] As a further limitation of this technical solution, the upper contact assembly includes an upper hollow round rod, which is fixedly connected to four evenly distributed upper contact points. The lower contact assembly includes a lower hollow round rod, which is fixedly connected to two evenly distributed lower contact points. The connecting assembly includes a connecting handle, which is connected to a mounting rod. One mounting rod is fixedly connected to the upper hollow round rod, and the other mounting rod is fixedly connected to the lower hollow round rod. The connecting handle is fixedly connected to two triangular protrusions, and the connecting handle and the two triangular protrusions form a mounting groove. The two ends of the exposed spring are respectively disposed in the corresponding mounting grooves. By providing mounting grooves, the installation of the exposed spring is facilitated.

[0009] As a further limitation of this technical solution, the two ends of the exposed spring are respectively fixedly connected to the corresponding mounting rods, and the connection between the exposed spring and the mounting rods is more secure during testing.

[0010] As a further limitation of this technical solution, the two connecting handles are in contact with each other.

[0011] As a further limitation of this technical solution, the upper contact end and the lower contact end are formed by die stamping and the two ends are rolled round to ensure that the hardness of the lower contact point and the upper contact point meets the standard.

[0012] As a further limitation of this technical solution, the exposed spring is a machined part and is manufactured using a spring mechanism.

[0013] As a further limitation of this technical solution, the total length of the upper contact end is 3.85mm, and the total length of the lower contact end is 2.2mm.

[0014] Compared with related technologies, the novel stamped assembly spring pin provided by this utility model has the following beneficial effects:

[0015] (1) The upper contact end and lower contact end of this device can be connected with the exposed spring by interference fit and assembled into a finished spring needle;

[0016] (2) The upper and lower contact ends of this device can be compressed and moved towards the middle to contact the PCB and the chip, thereby realizing the detection;

[0017] (3) This device has superior electrical performance compared to ordinary springs, better service life and contact, and is applicable to more scenarios. Attached Figure Description
