Description

Technical Field

[0001] The utility model relates to the technical field of signal lightning arresters, and particularly relates to a high-frequency signal lightning arrester. Background Technique

[0002] A signal lightning arrester is a lightning protection device specifically used for signal devices such as networks, communications, optical cables, broadcasts, televisions, monitors, videos, etc. The signal lightning arrester can effectively suppress lightning electromagnetic pulses, protect electronic devices from being damaged by them, block overvoltage and overcurrent. In thunderstorm weather, electronic devices may be impacted by overvoltage and overcurrent.

[0003] Chinese Patent CN2265608Y proposed a high-frequency signal lightning arrester. The structural composition of the high-frequency signal lightning arrester includes: an input terminal, an output terminal, a central conductor at the input end, a central conductor at the output end, a shielding body, an open-circuit coupling inductor, a discharge tube, a ground wire, and a ground wire insulation hole. Among them, the input terminal uses a TV antenna socket, and the output terminal uses a TV antenna plug; the open-circuit coupling inductor adopts a multi-pin shape with a spacing of 0.5 mm to 5 mm; the shielding body uses a metal material or a plastic material plated with a metal conductive layer, and the shape can be cylindrical or polygonal. Due to the adoption of the open-circuit coupling inductor, not only can high-frequency signals be transmitted normally, but also the lightning strikes of power frequency and lower frequencies are blocked, which plays a protective role for devices such as communication receivers and TV receivers. The shielding body is a common metal material or a plastic material plated with a metal layer. Therefore, the materials are easy to obtain, the processing is simple, and its cost is equivalent to one-fifth to one-tenth of that of a coaxial lightning arrester.

[0004] The above scheme greatly reduces the cost of the product. It is not only suitable for the selection of devices in the high-frequency communication field, but also can be widely used as a lightning arrester for TV receivers in ordinary families. However, the above scheme cannot strengthen the connection of the connector, and the connecting wire is easily affected by the outside and loosened, which will lead to poor contact and reduce the stability of the use of the high-frequency signal lightning arrester. Content of the Utility Model

[0005] The purpose of the utility model is to provide a high-frequency signal lightning arrester to solve the above problems. The device uses the cooperation among the connector, the first thermal expansion and contraction ring, the transmission head, and the transmission line to make the connection more firm, avoid the transmission head from being loosened due to the influence of the outside and resulting in poor contact, and make the high-frequency signal lightning arrester use more stably, solving the problems mentioned in the background technique.

[0007] A high-frequency signal lightning arrester includes a protective housing, a signal lightning arrester body, a connector, a first thermal expansion and contraction ring, a transmission head, and a transmission line. The signal lightning arrester body is fixedly installed inside the protective housing. A connector is fixedly installed on one side of the protective housing. A first thermal expansion and contraction ring is fixedly installed inside the connector. A transmission head is movably connected inside the first thermal expansion and contraction ring.

[0008] As a preferred solution of the present utility model, an input terminal is fixedly installed on the other side of the protective housing. An output terminal is fixedly installed on the outer side of the protective housing and away from the input terminal. A maintenance component is provided on the top of the protective housing.

A sealing gasket is fixedly installed on the bottom of the maintenance plate. A sealing groove is provided at the outer end of the sealing gasket. The sealing groove is opened on the top of the protective housing.

[0011] As a preferred solution of the present utility model, the protective component includes a liquid inlet pipe. The liquid inlet pipe is fixedly installed on the outer side of the protective housing and away from the connector. A filter screen is fixedly installed inside the liquid inlet pipe.
