What Does Safe High Voltage Connector (SHV Connector) Mean?
A safe high voltage (SHV) connector terminates a coaxial cable with a specific type of RF connector with extra insulation for handling high-voltage connections. Engineers have also introduced other features like those connecting a high-voltage contact before a ground contact, in order to provide additional safety for these types of connections.
Techopedia Explains Safe High Voltage Connector (SHV Connector)
In general, SHV connectors use a "bayonet"-style design where a thin protruding stylus is shielded by a thicker cable and is often attached with a metal nut or some other coupling. These types of connections are made familiar to consumers through their use in conventional coaxial cables serving cable television hookups.
Safe high-voltage connectors may also come with features such as sturdy metal mounts for panel or wall mounting. Connectors may come with a double-end terminal or an open-wire lead on one end. Producers generally provide "mating" information to determine the compatibility between coaxial cable connections and how these connectors are designed to fit into specific hardware systems.
