Embodiment 1

[0022] Embodiment 1: as Figure 1 to Figure 3 In the shown embodiment, a protection verification test wiring structure includes

[0023] An outer insulating sleeve 1, an extended conductive rod 2 and a test lead, the test lead includes a lead body and a plug connector 3;

[0024] The extended conductive rod includes an upper rod section 21 and a lower rod section 22 coaxially connected with the upper rod section. The lower rod section is provided with external threads, the outer insulating sleeve is set outside the upper rod section, and the upper end of the upper rod section is provided with a plug joint. Adapted socket;

[0025] The outer insulating sleeve includes a rotating grip square sleeve 11 and an extending round sleeve 12 arranged at the lower end of the rotating grip square sleeve. The rotating grip square sleeve is connected with the extending round sleeve. high.

[0026] In the axial direction of the extension sleeve: the projection of the extension sleeve fall...

Embodiment 2

[0029] Embodiment 2: the basic structure and implementation mode of this embodiment are the same as embodiment 1, and its difference is, as Figure 2 to Figure 4 As shown in , the lower rod section is provided with a column groove 41 opening at the lower end of the lower rod section. The column groove is provided with a conductive ejector rod 42 that slides and fits with the column groove. The conductive ejector rod includes a rod body 421 and is used for the contact test. The conductive hemispherical head 422 of the metal part of the terminal row is provided with a spring 43 in the column groove, one end of the spring is connected to the lower rod section, and the other end of the spring is connected to the conductive ejector rod.

[0030] The column groove, the conductive mandrel and the spring are coaxially arranged, and in the axial direction of the conductive mandrel: the spring, the rod body and the conductive hemispherical head are arranged in sequence.

[0031] In this...

Abstract

The invention discloses a protection verification test wiring structure, and the structure comprises an external insulating sleeve, an extended conductive rod, and a test lead wire. The test lead wirecomprises a conductor body and a plug connector. The extended conductive rod comprises an upper rod segment and a lower rod segment in coaxial connection with the upper rod segment. The lower rod segment is provided with an external thread, and the external insulating sleeve is disposed on the upper rod segment. The upper end of the upper rod segment is provided with a port adapted to the plug connector. The external insulating sleeve comprises a rotary holding square sleeve and an extending circular sleeve disposed at the lower end of the rotary holding square sleeve. The rotary holding square sleeve is connected with the extending circular sleeve. The uppermost point of the upper rod segment is lower than the uppermost point of the external insulating sleeve. The beneficial effects of the invention are that the structure is reasonable, can effectively assist a protection verification test, can guarantee the good connection stability between structures in a test process, and can effectively avoid the poor contact.

Description

technical field [0001] The invention belongs to the technical field of protection verification tests, in particular to a connection structure for protection verification tests. Background technique [0002] Relay protection verification test is a common test in the electric power field, which is completed relying on test wiring and pre-set test terminal blocks. The test terminal block includes the main seat of the terminal block and a number of test holes opened on the main seat of the terminal block (in order to facilitate the test operation, the test holes are usually opened upward and set vertically, and the main seat of the terminal block is made of insulating material) , There is a metal part in the test hole for contacting with the test wiring, and the test wiring includes the lead body and the test lead. At present, the test is carried out by directly extending the test lead wire from the test hole and touching the metal part in the test hole. During the test, proble...
