The invention provides a self-protection
test probe with a protection function and a manufacturing method thereof. In the
test probe, a clamping cap is fixed at the front end of a probe
barrel, an endcap, the probe
barrel, a probe head and a clamping head are coordinated to form a
test probe body in turn, and a probe of a telescopic test probe is circular with a
diameter of 0.3-0.6 mm; a
test line penetrates through the end cap, the front end is arranged in the probe
barrel, the telescopic test probe penetrates through the clamping head and probe head, the probe extends out the clamping head,the end is set in the barrel barrel, the
test line is communicated with the telescopic test probe, the communicated part is fixed in the clamping cap, and the clamping cap, the probe head and the clamping head are used for protecting the telescopic test probe; according to the method, a line input end of the
test line is communicated with the telescopic test probe, the end cap of an automatic pencil is slotted, the end cap and the probe barrel of the automatic pencil penetrate through the test line, by expanding a slot on the clamping cap of the automatic pencil, the communicated part of thetest line of the telescopic test probe and a test instrument can be fixed, and finally, the test probe can be assembled.
