Description

Technical Field

[0001] The utility model relates to the technical field of high voltage testing, in particular to a quick-install resistor. Background Art

[0002] The existing Chinese utility model patent with publication number CN209980884U and name "A wave-modulating resistor and a lightning high-voltage generator using the same" discloses a wave-modulating resistor that fixes a base member, a hollow body, and two end covers into one by means of glue potting. However, after the potting, it is necessary to wait for the potting glue to solidify, which results in a long production cycle, low production efficiency, and high production costs. Utility Model Content

[0003] The purpose of the utility model is to provide a quick-install resistor which can shorten the production cycle, improve production efficiency and reduce production costs in view of the shortcomings of the prior art.

[0004] In order to achieve the above utility model purpose, the technical solution of the utility model quick-install resistor is:

[0005] A quick-install resistor comprises a substrate, connecting pieces are arranged at both ends of the substrate, a resistance wire is arranged between the two connecting pieces and is wound around the substrate, a tube sleeve is sleeved on the outer side of the substrate, cover plates for sealing the tube sleeve openings are arranged on both sides of the tube sleeve, a slot is arranged in the middle of the cover plate, through holes are arranged on both sides of the slot, and fasteners are passed through the through holes to be fixedly connected to the substrate.

[0006] Preferably, the side wall of the cover plate is provided with a limiting boss for blocking the movement of the pipe sleeve.

[0007] Preferably, the connecting piece is a hook-type connecting piece or a U-shaped connecting piece.

[0008] Preferably, the fastener is an epoxy bolt or an epoxy taper pin.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] 1. After the cover plate passes through the connecting piece and is inserted into the pipe sleeve, a shell is formed on the outside of the substrate. Fasteners are directly used to penetrate the through holes and fix them to the substrate, so that a stable structure is formed between the substrate and the shell. There is no need to cure by glue pouring, which shortens the production cycle, improves production efficiency, and reduces production costs.

[0011] 2. If the resistor is damaged during use, first remove the cover and sleeve, then remove the damaged resistor wire, replace it with a new resistor wire, quickly form a new resistor, and avoid material waste. BRIEF DESCRIPTION OF THE DRAWINGS
