Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a relay protection tester interface conversion protection device, which comprises a housin 1, pole 7 in the inner chamber of casing 1 is equipped with, the outside of pole 7 is equipped with flange 8 and two springs 9 in, flange 8 is the integrated into one piece structure with interior pole 7, two springs 9 set up about the 8 symmetries of flange, connecting rod 6 and standard interface 2 have been run through respectively at the both ends of casing 1, connecting rod 6 and standard interface 2 one side that is close to mutually have all been seted up and have been held chamber 13, the both ends of pole 7 penetrate two inside that hold chamber 13 respectively in interior pole, the end fixing of connecting rod 6 has copper sheet 5, copper sheet 5 is used for and is connected with the corresponding terminal of signal terminal row.
