Description

Technical Field

[0001] This utility model relates to the field of test probe technology, and in particular to a reed tube integrated test probe. Background Technology

[0002] Probes are a crucial component in electronic product connectors. Existing probes typically employ a sliding pin combined with a helical spring. In practical use, current easily concentrates in a tiny area around the helical spring and the contact area between the spring and the probe tube. With existing probes, if the current is small, the flow through this tiny path does not affect the probe's lifespan. However, when the probe needs to carry a large current, the current concentration through the helical spring and the tiny contact area can easily deteriorate, causing material melting or changes in thermal properties, thus affecting the probe's lifespan. Furthermore, because the spring is built into the tube, the overall probe structure is more complex, increasing manufacturing difficulty and cost. Therefore, it is necessary to design a new test probe to meet production needs. Utility Model Content

[0024] The preferred embodiment of this utility model is a reed-tube integrated test probe, such as... Figure 1As shown, the probe includes a needle body 10, with narrowed sections 20 at both ends having reduced outer diameters. One narrowed section 20 has multiple contact tips 30 arranged circumferentially at its end, and the other narrowed section 20 has a first converging portion 40 at its end. An integrated spring section 50 is located on the needle body 10 between the two narrowed sections 20.

Compared with the traditional probe that uses a built-in separate spring and sliding needle, the integrated design can withstand higher current values. The overall structure has no contact resistance, has a longer service life, is easier to process, and has a lower cost.

[0025] In this embodiment, among the two narrowing sections 20, one narrowing section 20 with a contact tip 30 is a test end 60, and the other narrowing section 20 with a first gathering portion 40 is a wiring end 70. The multiple contact tips 30 of the test end 60 are used for contacting the test board. Specifically, the end of the narrowing section 20 corresponding to the test end 60 has a second gathering portion 80. The sidewall of the second gathering portion 80 has multiple notches 90 distributed circumferentially. The part of the second gathering portion 80 located between two adjacent notches 90 forms the contact tip 30. The notches 90 are V-shaped grooves with their smaller ends facing the spring section 50, thereby making the end diameter of the contact tip 30 small enough to test products with higher accuracy requirements.

[0026] In this embodiment, the inner diameter of the annular structure formed by the multiple contact tips 30 is 0.27 mm, the axial length of the second gathering part 80 is 0.25 mm, and the axial length of the first gathering part 40 is 0.2 mm.

The end of the transition section 100 facing the spring section 50 has an arc-shaped transition section 110 corresponding to the end of the spring section 50. The arc-shaped transition section 110 is semi-circular and its diameter is the same as the wire diameter of the spring section 50. Together, they serve to disperse stress and ensure the long-term stability of the end of the spring section 50.
