Description

Multi-stage elastic conductive probe

This creation relates to a multi-segment elastic conductive probe, especially a multi-segment elastic conductive probe that obtains a large compression with a small pressure.

At present, in order to obtain better contact conductivity, the conductive probes used in testing tools need to use a larger pressure and increase the compression amount of the conductive probes to avoid poor contact and affect the test. However, the diameter of the general conductive probe is generally smaller than 3 cm because the diameter of the needle body is small, and the structure of the conductive probe has only a single spring to increase the contact conductivity. Therefore, in the case of a common conductive probe with a small needle diameter and a single spring, in order to obtain good contact conductivity, the pressure of the conductive probe on the test product must be increased. In this way, the conductive probe with a small needle diameter is likely to cause damage to the test product, and the high pressure operation is also likely to cause the loss of the conductive probe, which makes it difficult to achieve the ideal test effect during the test operation. How can a large pressure be obtained with a small pressure? Compressed conductive probes are a necessary improvement for general conductive probes.

In view of this, it is necessary to provide a multi-stage elastic conductive probe which obtains a large amount of compression with a small pressure.

The present invention provides a multi-section elastic conductive probe, which includes a contact portion, at least one support portion, and a fixing portion. The contact portion is sleeved on one end of the support portion, and the other end of the support portion is sleeved on the fixing portion. The socket of the contact portion and the support portion has a first buckle portion and a first elastic member, so that the contact portion is telescopically disposed at one end of the support portion, and the socket of the support portion and the fixed portion There is a second buckle portion and a second elastic member, the support portion is telescopically disposed on the fixing portion, and the contact portion is contracted toward the support portion by being pressed, and the support portion is contracted toward the fixing portion at the same time.

Compared with the prior art, the novel multi-stage elastic conductive probe is created by the elastic multi-section socket structure between the contact portion, the support portion and the fixed portion, so that the conductive probe can achieve good compression with a small pressure. Practical performance.

Please refer to FIG. 3 again, which is a cross-sectional view of the contact pressure state of the multi-stage elastic conductive probe of FIG. 1. When the multi-stage elastic conductive probe 100 is tested, the contact end 12 of the contact portion 10 is subjected to a pressure (not shown) on the contact portion 10. The contact portion 10 receives the pressure and is located in the contact portion 10 The first elastic member 42 inside one end of the supporting portion 20 is stressed. With the multi-stage telescopic structure of the multi-stage elastic conductive probe 100, when the first elastic member 42 is stressed, the second elastic member 52 located at the other end of the support portion 20 is also simultaneously stressed, and due to the acting force and the reaction In a force relationship, the forces of the first elastic member 42 and the second elastic member 52 will be the same. Therefore, when a single pressure acts on the contact portion 10, the first elastic member 42 and the second elastic member 52 are driven by the same force at the same time. In this embodiment, the first elastic member 42 is forced to cause the contact portion 10 to contract to one end of the support portion 20, and the second elastic member 52 is subjected to the force to cause the support portion 20 to be contracted to the fixing portion 30. Therefore, a single force of the contact portion 10 can drive the contact portion 10 and the support portion 20 to perform two-stage contraction. Moreover, if the elastic coefficient K of the first elastic member 42 and the second elastic member 52 and the gravity of the support portion 20 are not calculated, the force of the first elastic member 42 and the second elastic member 52 will be the same.

Compared to a single spring compression to produce a double contraction variable, it is obviously necessary to double the pressure. Finally, the contact portion 10, the support portion 20 and the fixing portion 30 are rod-shaped bodies, the first protruding portion 401, the second protruding portion 403, the third protruding portion 501, and the fourth protruding portion. The rising portions 503 are ring-shaped protrusions. The space formed by the ring-shaped protrusions in the first recessed hole 22 and the second sleeve 34 makes the contact portion 10 perform a telescopic operation on one end of the support portion 20. The other end of the supporting portion 20 performs a telescoping operation on the fixing portion 30. The multi-stage telescopic structure of the multi-stage elastic conductive probe 100 can achieve a good practical effect of obtaining a large compression amount with a small pressure.

This multi-segment elastic conductive probe 100 is created by the elastic multi-segment socket structure between the contact portion 10, the support portion 20 and the fixing portion 30, so that the multi-segment elastic conductive probe 100 achieves large compression with low pressure Good practical performance.
