[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 The utility model provides a technical solution: an outdoor high-voltage vacuum circuit breaker upper outlet, comprising a mounting plate 1, a fixing hole 2, a first fixing threaded hole 201, a second fixing threaded hole 202, an embossed pattern 3, a protective mechanism 4, a protective cloth layer 401, a Velcro adhesive surface 402, a Velcro fur surface 403, an auxiliary mechanism 5, a leather plug 501, a groove 502, a mini screwdriver 6, an arc sleeve 7, a mounting threaded hole 8, a clamping block 9 and a clamping threaded hole 10;

[0023] When it is necessary to fix the upper outlet device on the vacuum circuit breaker, a mounting threaded hole 8 is provided in the arc sleeve 7, and the mounting threaded hole 8 is aligned with the corresponding mounting bolt on the vacuum circuit breaker, and then the arc sleeve 7 is rotated so that the mounting threaded hole 8 rotates on the mounting bolt, and the mounting threaded hole 8 and the mounting bolt are tightened. Clamping blocks 9 are fixedly installed at both ends of the front side of the arc sleeve 7, and clamping threaded holes 10 are provided at the front and rear ends of the clamping blocks 9. A clamping bolt adapted to the clamping threaded hole 10 is passed through one of the clamping threaded holes 10, and the two clamping threaded holes 10 are pinched together, and the clamping bolt is screwed into the other clamping threaded hole 10, so that the two clamping threaded holes 10 are clamped to each other, so that the arc sleeve 7 clamps the mounting bolt;

[0024] When the upper outlet device needs to be connected to an external line, the copper terminal connection hole connected to the external line is placed on the mounting plate 1, and a fixing hole 2 is opened on the mounting plate 1. Figure 2As shown, the fixing hole 2 includes a first fixing threaded hole 201 and a second fixing threaded hole 202. The first fixing threaded hole 201 and the second fixing threaded hole 202 are two holes with different aperture sizes. The connecting hole on the copper terminal is aligned with the aperture of the corresponding size of the mounting plate 1, and two fixing bolts adapted to the holes on the copper terminal are screwed into the connecting hole of the copper terminal, and then the first fixing threaded hole 201 and the second fixing threaded hole 202 are screwed into the first fixing threaded hole 201 and the second fixing threaded hole 202 respectively, so that the copper terminal and the mounting plate 1 are clamped to each other, so that the mounting plate 1 is fixedly connected to the external line. Since the rectangular circular hole outside the first fixing threaded hole 201 has a certain length, and the width of the first fixing threaded hole 201 is the same as the diameter of the second fixing threaded hole 202, no matter what standard copper terminal is selected, the first fixing threaded hole 201 and the second fixing threaded hole 202 can be used at the same time, can be installed normally, and can be fastened with two fastening screws, so that the product fits better and has better conductive performance.

[0025] The outdoor high-voltage vacuum circuit breaker has a protective mechanism 4 installed on the rear side of the upper outgoing line. Figure 3 and Figure 4 As shown, the protection mechanism 4 includes a protective cloth layer 401, a Velcro adhesive surface 402 and a Velcro fleece surface 403. The protective cloth layer 401 is fixedly connected to the rear side of the mounting plate 1. After the mounting plate 1 is connected to the copper terminal of the external line connection end, the protective cloth layer 401 is wrapped around the mounting plate from the rear side to the front. The Velcro adhesive surface 402 and the Velcro fleece surface 403 are respectively fixedly installed on the inner and outer sides of the protective cloth layer 401. The Velcro adhesive surface 402 and the Velcro fleece surface 403 can be connected correspondingly to wrap the mounting plate 1 and the external line connection end, so as to protect them. The protective cloth layer 401 is waterproof, which can reduce the contact between the connection and water, and increase the service life of the device and the fixing bolts.

[0026] The outdoor high-voltage vacuum circuit breaker is provided with an auxiliary mechanism 5 on the front side of the upper outgoing line. Figure 1 As shown, the auxiliary mechanism 5 includes a leather plug 501 and a groove 502, and a mini screwdriver 6 is arranged in the groove 502. When the device needs to be handled urgently and no tools are brought with you, the leather plug 501 plugged in the mouth of the groove 502 is opened, and the screwdriver 6 inside is taken out, so that it can be quickly disassembled. After use, it is put into the groove 502 and plugged with the leather plug 501 for easy use next time.
