Embodiment Construction

[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0017] See figure 1 , A test finger 100 with a warning device in the first embodiment of the present invention is provided. The test finger 100 includes a handle 10, a baffle 11, an extension portion 12, and a test portion 13, which are sequentially connected, as shown in 1-a, wherein, The handle 10, the baffle 11, and the extension portion 12 are all made of insulating material, and the test portion 13 is made of conductive material, and the size of the test portion 13 is similar to that of a human finger. The test finger 100 also includes a warning device 14. In this embodiment, the warning device 14 is arranged at the end of the handle 10 away from the baffle 11. In other embodiments, the warning device 14 can also be arranged in other positions. . The warning device 14 includes multiple electronic devices, as shown in 1-b. In this embodiment, the warning d...

Abstract

The invention provides a test finger with a warning device, the test finger is used for testing whether the distance of a bare point on a circuit board complies with the safety distance stipulated in the safety regulations, and the test finger includes a handle, a baffle, an extension connected in sequence part and the testing part, the testing finger also includes a warning device arranged at the end of the handle, when the testing part causes the short circuit of the exposed point, the warning device will send out a warning message, which provides a reliable guarantee for the qualification test of the circuit board .

Description

Technical field [0001] The invention relates to a test finger, in particular to a test finger with a warning device. Background technique [0002] In the production process of a circuit board with a large number of components, the distance between adjacent exposed points on the circuit board must comply with the safety distance specified in safety regulations to avoid personal injury caused by short-circuit of exposed points. In the circuit board qualification test, a safety test finger is commonly used to test the distance between two adjacent exposed points, and the tester visually judges whether the test finger causes a short circuit of the exposed point. However, in today's circuit boards that mostly use surface mount devices (SMD), it is difficult for this test method to accurately determine whether the exposed points are short-circuited, and it is easy to cause unqualified products to flow out. Summary of the invention [0003] In view of this, it is necessary to provide a ...
