Description

Technical Field

[0001] The utility model relates to the technical field of gas discharge tube accessories, in particular to a gas discharge tube pin protection cover. Background Art

[0002] The gas discharge tube is a switch-type protection device, usually used as an overvoltage protection device. The gas discharge tube currently used generally includes an insulating tube body and electrodes sealed at both ends. An appropriate amount of inert gas medium is filled between the insulating tube body and the electrodes sealed at both ends, and electron emission materials (such as electron powder) are coated on the opposite surfaces of the two electrodes. When the voltage at both ends of the gas discharge tube electrodes exceeds the breakdown voltage of the gas, it will cause gap discharge, and the gas discharge tube will quickly change from a high resistance state to a low resistance state, forming a conduction, thereby protecting other devices connected in parallel with the gas discharge tube. The pins at both ends of the gas discharge tube are important components. When packaging and transporting, they need to be protected by protective covers on the outside. Most of the current gas discharge tube pin protective covers are installed individually, and they need to be manually arranged and stacked after installation, which is inconvenient to use. Pins of different lengths require different protective covers, which is extremely inconvenient to use. Utility Model Content

[0003] The utility model aims to provide a gas discharge tube pin protection cover to solve the problem that most of the gas discharge tube pin protection covers proposed in the above background technology are installed individually, and they need to be manually arranged and stacked after installation, which is inconvenient to use. Different lengths of pins require different protection covers, which is extremely inconvenient to use.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A gas discharge tube pin protection cover, comprising a lower row cover and an upper row cover for protecting the pins of the gas discharge tube;

[0006] The lower row sleeve and the upper row sleeve both include a plurality of sleeves evenly and equidistantly arranged, and adjacent sleeves are connected by connecting blocks. Each sleeve is provided with a slot that matches the diameter of the pin and is plug-fitted.

[0007] Preferably, the connecting block and the sleeve are integrally formed, and the connecting block is made of soft silicone material with good toughness.

[0008] Preferably, the sleeve comprises a plastic layer, and an anti-collision shell is provided on the outer wall of the plastic layer.

[0009] Preferably, the plastic layer is made of PVC material and has a thickness of 2-3 mm.

[0010] Preferably, the anti-collision shell is made of metal film material and has a thickness of 0.5-1 mm.

[0011] Preferably, a shock-absorbing ring is installed on the inner wall of the plastic layer.

[0012] Preferably, the shock-absorbing ring is made of silicone material and has a thickness of 1-2 mm.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. In the gas discharge tube pin protection cover, multiple groups of gas discharge tubes can be arranged and stored at the same time by setting the lower row cover and the upper row cover, which is convenient for packaging and transportation and easy to use. The slots opened on the sleeve can protect the pins of the gas discharge tube, save space, and can fix gas discharge tubes with pins of different lengths, which is convenient for promotion.

[0015] 2. In the pin protective cover of the gas discharge tube, the sleeve includes a plastic layer, and an anti-collision shell is arranged on the outer wall of the plastic layer. The plastic layer is made of PVC material with a thickness of 2-3mm, and the anti-collision shell is made of metal film material with a thickness of 0.5-1mm. The anti-collision effect is improved by setting the anti-collision shell to prevent damage caused by crushing or collision.

[0016] 3. In the pin protection cover of the gas discharge tube, a shock-absorbing ring is installed on the inner wall of the plastic layer. The shock-absorbing ring is made of silicone material and has a thickness of 1-2 mm. The shock-absorbing ring can improve the shock-absorbing effect and also has a buffering effect, and the transportation loss is greatly reduced. BRIEF DESCRIPTION OF THE DRAWINGS
