A substructure for the antenna head of a transmit frequency intercom

Abstract

This utility model relates to the field of walkie-talkie technology, and in particular to an antenna head core structure for a walkie-talkie with a transmission frequency. It includes a connecting female base with a first insertion hole; a core insulating sleeve with a second insertion hole, the inner wall of which is evenly provided with first protruding teeth; and an antenna head insertion core, including a terminal insertion end, a fixed end, and a connecting end. The connecting end connects to the walkie-talkie's signal receiver. The fixed end has second protruding teeth on its circumferential surface. The terminal insertion end has a insertion hole, and the circumferential side wall of the insertion hole has multiple ports, forming multiple arc-shaped spring edges on the side of the insertion hole. The insertion hole and the arc-shaped spring edges on the side of the terminal insertion end increase the contact area with the terminal, improving the elasticity and buffering capacity of the connection. Even if the terminal or terminal insertion end deforms, at least one or more of the arc-shaped spring edges will contact the terminal, effectively preventing the problem of communication loss due to terminal deformation and loosening caused by external forces.
