Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for mounting an antenna in a transmitter or a receiver.

[0002]

2. Description of the Related Art In radio controlled transmitters and the like, a mounting plate 101 as shown in FIG. 2 is provided on an inner surface of a case 100 so as to mount an antenna. A notch 102 is formed at the tip of the mounting plate 101.
A terminal 106 is attached to the lower surface of the through the notch 102 by a screw 103, a washer 104, and a nut 105. A female screw 108 is provided on the lower end of the antenna 107.
Is cut and fixed by being screwed into the screw 103 projecting to the upper surface side of the mounting plate 101. The terminal 106 is connected to the printed circuit board in the case 100.

[0003]

The antenna mounting structure described above has the following problems. (1) In addition to the antenna 107 and the case 100, four parts are required, and the number of parts is large. (2) As shown in FIG. 3, since the nut driver 109 and the driver 110 are used to fasten the screw 103 and the nut 105 to the mounting plate 101, the shape of the case 100 must be such that these tools do not interfere with each other. Must be constrained in design. (3) When the antenna 107 is rotated to remove it, the nut 105 may also rotate and become loose.

It is an object of the present invention to provide an antenna mounting structure that has a small number of parts and is easy and secure to attach and detach the antenna.

[0005]

An antenna mounting structure for a transmitter / receiver according to the present invention is provided in an inner surface of a case of the transmitter / receiver, and has a cylindrical shape with an open upper surface and a front surface.
It has a mounting portion formed in the wall portion and having a groove opened on the front surface, and a terminal member mounted on the mounting portion. The terminal member includes a mounting flange that is inserted into the groove of the mounting portion, a retaining means that fixes the mounting flange in the groove, and a circumferential groove formed in the base portion of the antenna, which is elastically elastic from opposite directions. It is provided with a pair of engaging portions that engage with each other, and a terminal portion that is connected to a circuit board provided inside the case.

[0006]

The terminal member is mounted on the mounting portion of the case, and the base of the antenna is mounted on the terminal member. The locking portion of the terminal member elastically engages with the groove of the antenna, and the antenna is securely fixed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, a resin case 1 of a transmitter or a receiver has a mounting portion 2 integrally formed on its inner surface side. The mounting portion 2 is composed of a pair of left and right side walls 3 and 3 and a bottom plate 4, and has a rectangular tube shape with an open top and front. Between the side walls 3, 3 and the bottom plate 4, there are grooves 5, 5 respectively.
Are formed. The groove 5 is formed along the plane of the bottom plate 4, opens on the front surface of the mounting portion 2, and reaches a position approximately half the depth of the mounting portion 2. A step portion 6 which is higher than the plane of the bottom plate 4 is formed in the central portion of the bottom plate 4 along the rear end surface of the groove 5. A receiving plate 8 for an antenna 7, which will be described later, is provided on the step portion 6.

Reference numeral 9 is a terminal member mounted on the mounting portion 2. The terminal member 9 is a component formed by molding a single metal plate, and a pair of side plates 11, 11 continuous to the left and right of the base 10 face each other with a predetermined interval. The upper portions of the pair of side plates 11 and 11 are formed with engaging portions 12 and 12 projecting inwardly in a mountain shape, respectively, so that a base portion of an antenna 7 described later can be elastically sandwiched.

Mounting flanges 13 and 13 are provided on the outer sides of the lower ends of the side plates 11 and 11 of the mounting portion 9 so as to be inserted into the grooves 5 of the mounting portion 2. A part of the mounting flange 13 is cut out in a rectangular shape, and the front surface side is lifted up to serve as a retaining member 14 for the mounting flange 13 inserted in the groove 5.

A terminal portion 15 is provided at the lower end of the base portion 10 of the terminal member 9 so as to be connected to a circuit board (not shown) provided in the case 1.

A peripheral groove 16 is formed at the lower end of the antenna 7. To attach this antenna 7 to the case 1,
First, the terminal member 9 is mounted in the mounting portion 2. The flange 13 of the terminal member 9 is inserted into the groove 5, and the terminal member 9 is pushed into the mounting portion 2 until the side plate 11 contacts the step 6. The position of the terminal member 9 is determined by the step 6 and the retaining member 14.

The peripheral groove 16 at the lower end of the antenna 7 is attached to the mounting portion 2.
The engaging portions 12, 12 of the terminal member 9 mounted therein are inserted from the front side. By inserting the antenna 7, the pair of locking portions 12, 12 and the side plates 11, 11 are expanded, and the locking portion 12
The tip of the chevron is engaged with the circumferential groove 16 with a predetermined force. As a result, the antenna 7 is mechanically fixed to the terminal member 9 and also electrically connected. Here, if the side plates 11 and 11 of the terminal member 9 and the side walls 3 and 3 of the mounting portion 2 are expanded along with the insertion of the antenna 7, the fixing of the antenna 7 becomes more reliable. Since the antenna 7 contacts the receiving plate 8, the antenna 7 is prevented from being displaced and positioned.

The terminal portion 15 of the terminal member 9 is directly soldered to a terminal of a circuit board (not shown).

[0014]

According to the present invention, the mounting flange of the terminal member is inserted into the groove of the U-shaped mounting portion provided on the case, and the terminal member mounted on the mounting portion is fixed by the retaining means. The peripheral groove of the antenna is detachably fixed by a pair of locking portions provided on the terminal member.

Therefore, according to the present invention, the following effects can be obtained. (1) The number of parts has decreased, and the number of assembly steps has decreased. (2) A tool for assembling is unnecessary, the shape of the case is not restricted by the convenience of assembly, and the degree of freedom in design is increased. (3) The work of attaching the terminal member to the case is simple and reliable, and the antenna can be easily attached / detached with one touch without removing the attached terminal member from the case.
