Detailed Description

Referring to fig. 1, the three-phase six-column overvoltage protector comprises a shell 1, wherein a binding post 11 is fixedly installed on the shell 1, a binding post 12 is connected to the binding post 11, a grounding terminal 13 is arranged on the shell 1, a protective sleeve 14 tightly attached to the shell 1 is sleeved on the binding post 11, a threaded ring 15 is fixedly embedded into the protective sleeve 14, a threaded knob 16 is arranged on the threaded ring 15 in a threaded manner, a squeezing pad 17 is fixed on the threaded knob 16, and the squeezing pad 17 is tightly attached to the binding post 12 for contact.

Referring to fig. 1 and 2, an alignment rod 2 is fixed on a housing 1, adjacent protective sleeves 14 are fixed by a bracket, alignment seats 21 are fixed on the protective sleeves 14 and are in butt joint with the alignment rod 2, and four extrusion pads 17 are uniformly distributed.

Referring to fig. 1, a groove 3 is formed in the alignment rod 2, and a retractable bayonet 31 is fixed in the groove 3 through a spring 32, so as to ensure the retractable reset stability of the bayonet 31.

Referring to fig. 1, a through hole 33 is formed in the aligning base 21, and the locking pin 31 slidably penetrates through the through hole 33, so that the protecting sleeve 14 and the housing 1 can be assembled and butted conveniently.

Referring to fig. 1, a bearing 4 is fixed at the lower end of the housing 1, a shaft rod 41 is in interference fit in the bearing 4, and a twisting knob 42 is fixed at the end of the shaft rod 41 and can drive the shaft rod 41 to rotate to adjust the position of the mounting bracket 52.

Referring to fig. 1, two opposite and equal-length threaded bosses 43 are disposed on the shaft rod 41, a threaded sleeve 5 is disposed on the threaded bosses 43 in a threaded manner, and a square block 51 slidably attached to the housing 1 is fixedly wrapped on the threaded sleeve 5, so that the two mounting brackets 52 can be simultaneously and oppositely close to or far away from each other.

Referring to fig. 1, a mounting frame 52 is fixed at the lower end of the square block 51, and a mounting hole 53 is formed in the mounting frame 52, so that the external bracket can be conveniently and fixedly butted.

The working principle of the scheme is as follows: when the connection of linking line 12 and terminal 11 is protected to needs, before terminal 11 and casing 1 assemble, run through lag 14 with terminal 11 in, then dock with counterpoint pole 2 through counterpoint seat 21 for lag 14 can be fixed a position with casing 1, goes into through-hole 33 through bayonet 31 card in, accomplishes casing 1 and lag 14 fixed.
