Claims (1)

[Claims for Utility Model Registration] (1) A primary radiator and a converter are attached to the distal end of a support arm whose base end is connected to the parabolic reflector side and whose distal end extends toward the opening side of the parabolic reflector. The supporting arm has a cylindrical distal end, a locking portion provided along the opening edge on the inner surface of the distal end, and an input terminal provided on the inner surface of the distal end. The exterior part has an annular groove provided on its outer surface into which the tip of the support arm is inserted, and an annular groove provided on the outer surface of the exterior part inside the annular groove and electrically connected to the converter. an output connector that is electrically connected to the input terminal when the tip of the support arm is inserted into the groove; and an output connector that is provided on the outer surface of the exterior part inside the annular groove and the tip of the support arm. a spring-made engagement part that engages with a locking part of the support arm to maintain this inserted state when the part is inserted into the groove; Device. (2) The locking part of the support arm is a protrusion provided along the opening edge on the inner surface of the tip of the support arm, the engaging part is a thin plate made of a spring, and the base end is a ridge formed along the opening edge. The primary radiator according to claim (1), wherein the primary radiator is connected to the exterior part and is bent in a concave shape so that the tip side thereof engages with the protrusion of the support arm on the plate surface of the thin plate. and converter mounting equipment. (3) The locking part of the support arm is a through hole provided in the peripheral wall of the distal end; The primary radiator and converter according to claim (1), wherein the primary radiator and converter are bent in a dogleg shape, and are engaged when the doglegged bent portion enters the through hole. Mounting device. (4) The tip of the support arm is formed into a cylindrical shape with a non-circular cross section perpendicular to the cylindrical direction, and the groove of the exterior part is designed to allow the tip of the support arm to be inserted. The support arm has a shape such that when the distal end of the support arm is inserted into the groove of the exterior part, the exterior part does not rotate relative to the support arm in the circumferential direction of the groove. The primary radiator mounting device according to claim (1).
