Abstract

PURPOSE:To load and unload stably an antenna into and output of a resin protecting case with a simple constitution by providing plural elastic pawls to a supporting arm of the protecting case and engaging these pawls to the peripheral areas of a through hole of a cabinet. CONSTITUTION:Elastic pawls 1c and 1d are provided in a body at two areas in the lengthwise direction on the surface of a supporting arm 1b projecting at the center of an antenna store part 1a. Hollow parts 1e and 1f are formed at the center parts of the pawls 1c and 1d respectively, and taper surfaces 1g and 1h are formed at the front of the parts 1e and 1f. A protecting case 1 pushed into a cabinet 3, and the part 1e of the pawl 1c is engaged to the periphery of a through hole 3a. Thus an antenna can be stored. While the case 1 is pulled out linearly and the part 1f of the pawl 1d is engaged to the periphery of the hole 3a. Thus the antenna can be pulled out.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an antenna mounting device used in an AM receiver, etc., which has a simple structure and allows stable insertion and removal of the antenna. The antenna is attached to the back of the cabinet so that it can be moved in and out, but the structure of the antenna holder that allows the antenna to be inserted and removed is complicated and the production cost is high.
Moreover, in many cases, it was not possible to operate the antenna in and out smoothly.

The present invention provides an antenna mounting device that solves these problems.

An embodiment of the present invention will be described below with reference to the drawings.

In the figure, 1 is a protective case integrally formed of resin;
1a is an antenna storage part that stores a core wrapped with a coil, 1b is a support arm protruding from the center of the antenna storage part 1a, and IC, 1 (i is integrated at two locations in the longitudinal direction of the surface of the support arm 1b). The elastic claws 1e and 1f are provided in the respective elastic claws 1c.
The recesses 1g and 1h provided at the center of the recesses 18 and 1d are tapered surfaces provided in front of the recesses 18 and 1f. This protective case 1 is divided into two parts at the position of the dividing line 11, and the two parts are connected by a hinge part 1J provided in the antenna storage part 12L.

A lead wire 2 is drawn out from the rear end through the inside of the support arm 1b. On the other hand, 3 is a cabinet of the receiver, and a through hole 31L is formed in the rear surface of the cabinet, and an antenna holder 4 made of resin or the like is attached inside the through hole 3a. Incidentally, the upper surface of the antenna holder 4 is provided with a groove 4a through which the elastic claws IC and 1d pass. Note that the elastic claws 1c and 1d are attached to the antenna housing portion 1a.
Only the end of the support arm 1b is connected to the support arm 1b, and is constantly biased in the direction of lifting off the surface of the support arm 1b.

Therefore, as shown in FIGS. 1 and 4, the protective case 1
The antenna can be stored by pushing in the elastic claw 1c and engaging the Ω recess 1e around the through hole 3a. If the protective case is pulled out in a straight line as shown in FIG.
The antenna can be pulled out.

In this embodiment, the tapered surfaces 1g and 1h are provided on the front surface of the elastic claw IC, 1d, so that once the elastic claw 1G or 1d is pushed into the cabinet 3 and then the protective case 1 is pulled out, the elastic claw 1C or The tapered surfaces 1d can be pushed in to engage the periphery of the through hole 3'2L, and when disengaging the engagement, the tapered surfaces 1g and 1h need only be pushed lightly by hand.

Therefore, the antenna can be moved in and out very easily. Further, if both the support arm 1b and the antenna holder 4 are made of resin, the support arm can slide easily and the cost can be reduced.

As described above, in the present invention, the support arm of the protective case made of resin is inserted into and out of the through hole of the gabine 7), and the support arm is integrally provided with a plurality of elastic claws. By engaging the periphery of the through hole, the protective case is fixed in the housed state and in the pulled out state, so the antenna can be stably taken in and taken out with an extremely simple configuration.
