Lightning protection and grounding clips with optional length and easy locking

Abstract

The present invention discloses a lightning protection grounding clamp with a selectable usage length and convenient to lock. The lightning protection grounding clamp with the selectable usage length and convenient to lock comprises an antenna connecting device, a grounding cable and a connecting grounding bar device. The antenna connecting device comprises a fastening body, a first thermal shrinkage short tube and a first wiring terminal, one end of the first thermal shrinkage tube is connected with the first wiring terminal, and the first wiring terminal is connected with the fastening body. The connecting grounding bar device comprises a second thermal shrinkage short tube and a second wiring terminal, and the second thermal shrinkage short tube is connected with the second wiring terminal. The grounding cable is connected with the first thermal shrinkage short tube and the second thermal shrinkage short tube separately, wherein the fastening body is a strip-like sheet body, N (wherein N is greater than or equal to 1) cutting traces are arranged on the surface of the fastening body at certain intervals, locking jacks are arranged at the connection end of the fastening body and the first wiring terminal, and a clamping column is also arranged additionally. The lightning protection grounding clamp with selectable usage length and convenient to lock of the present invention is wide in use range, is convenient to install, and enables the contact resistance to be reduced.

Description

technical field [0001] The invention relates to the technical field of communication grounding, in particular to a lightning protection grounding clip with a wide range of use, an optional length and easy locking. Background technique [0002] In thunderstorm weather, the outdoor antenna is easily attacked by lightning, which will cause damage to the indoor electrical appliances connected to the other end of the antenna. In order to prevent indoor electrical appliances from being struck by lightning, a ground wire must be connected in parallel with the antenna. [0003] Ground clips are materials used to connect to outdoor ground bars. [0004] The grounding clips currently used all include: a connecting antenna device, a grounding cable and a connecting grounding bar device, wherein the connecting antenna device includes a card body, and the card body in the prior art is a square piece whose size is fixed and invariable. It cannot adapt to antennas of different specificat...

Problems solved by technology

[0004] The grounding clips currently used all include: a connecting antenna device, a grounding cable and a connecting grounding bar device, wherein the connecting antenna device includes a card body, and the card body in the prior art is a square piece whose size is fixed and invariable. Unable to adapt to antennas of different specifications, the use range is narrow

At the same time, the card body is wrapped around the outer periphery of the antenna, and the two sides of the card body are fixed by bolts. In this connection method, the card body and the antenna are not in close contact, resulting in a large contact resistance.
