The invention discloses a test terminal needle. The test terminal needle comprises two symmetrical needle bodies; the two needle bodies are in rotatable connection through a hinge pin; each needle body comprises a hook type shell, a metal needle and an insulation lifting cap; a plugging opening used for connecting a conventional test line is formed in each insulation lifting cap; each metal needle vertically passes through the lower end of a shell body at the upper part of the corresponding hook type shell and extends out from a corresponding spring; the hook type shell includes upper arms and lower arms; each upper arm is of a horizontal L-shaped structure; each lower arm is of a vertical L-shaped structure; the upper arms and the lower arms are combined to form a U-shaped structure; the vertical ends of the lower arms can move up and down along the vertical ends of the upper arms; slide grooves are formed at the tops of the upper arms; fastening screws are installed in the slide grooves; connection gaskets are arranged between the fastening screws and the metal needles; and the top end of each spring is fixedly connected with a corresponding connection gasket so as to form an integrated body. With the test terminal needle of the invention adopted, fast and safe connection of test lines and measured voltage terminals in relay protection operation can be realized. The test terminal needle has the advantages of safe and convenient use and wide use.
