However, in such a conventional antenna connection structure using a U-shaped antenna terminal or mounting means, first, the antenna terminal is soldered to a printed circuit board or an antenna support on the device body side. Since it has to be fixed by heat or caulking, there is a problem that the manufacturing process cannot be simplified and the efficiency cannot be improved.

As shown in FIGS. 5 and 6, the conventional antenna terminal has a very simple structure in which a leaf spring is bent in a U-shape, and at least one end is not fixed to a printed circuit board or antenna mounting means.

For this reason, the weight and volume of the antenna support and insert metal fittings hinder the reduction in size and weight of the device, and the cost for the molds and processing for the production of parts is increased. Since it is separately required, it has been a factor that hinders cost reduction of the wireless communication device.

The present invention has been proposed in order to solve such problems of the prior art. An antenna terminal for connecting an antenna and a substrate is elastically contacted between the device body, the antenna and the substrate. , The antenna terminal can be brought into contact with the antenna and the substrate without performing heat staking, soldering, or the like, and by providing a tapping screw on the outer periphery of the antenna, the antenna can be attached to the wall of the device body.

The terminal body 50 and each part are integrally formed by cutting and bending a leaf spring member. It is. Various materials such as a beryllium copper alloy and a SUS plate material can be selected for the antenna terminal 5 according to design items such as a shape and a necessary spring pressure. In addition, in order to improve connection reliability, it is usually preferable to perform gold plating.

As shown in FIG. 1, the terminal body 50 is disposed in a space surrounded by a screw boss 32 formed on the case back wall 30b of the case 3 and a plurality of ribs 36, 37, 39a, 39b. The screw boss 32 and the ribs 36, 3
The outer edges come into contact with 7, 39a, 39b and are positioned.

As shown in FIG. 1, the board contact portion 51 extends from the side of the terminal body 50 on the case side wall 30c side, and is bent so as to face the terminal body 50 via the bent portion 56. A leaf spring member that extends in the width direction of the formed device,

As shown in FIG. 1, the antenna contact portion 52 is a leaf spring member formed by cutting and raising the surface of the terminal main body 50 and extending in the height direction of the device. As shown in FIG. By being bent from the upper wall 30a side, the distal end portion comes into elastic contact with the terminal connecting portion 23 of the antenna holding bracket 2. As described above, the antenna contact portion 52 protrudes from the surface of the terminal body 50 and elastically contacts the terminal contact portion 23 of the antenna holder 2.

The bent portions on the four sides of the terminal body 50 are provided by bending a leaf spring member extending from the edge of the terminal body 50 to approximately 90 degrees so as to protrude into the antenna holding bracket 2.

4 is a rib 37, and a bent portion 55 is a screw boss portion 33.
The antenna terminal 5 is mounted on the case 3 so that the antenna terminal 5 is arranged and engaged so as not to get on the vehicle.

In the antenna terminal 5, the terminal body 50 is formed in a substantially square plate shape, but each bent portion has a shape corresponding to each rib and the screw boss portion 32 on the case 3 side. Therefore, the antenna terminal 5 cannot be mounted on the case 3 in a state where the antenna terminal 5 is rotated 90 degrees, 180 degrees, and 270 degrees about the mounting direction as a central axis from a normal mounting position. Therefore, the antenna terminal 5 of the present embodiment is not mounted in the wrong direction.

When the screw is screwed into the screw 32, a screw thread is threaded on the inner periphery of the tapping screw through hole 32 by the tapping screw portion 22, and the antenna holding bracket 2 is screwed to the case 3.

At the same time, the antenna contact portion 52 of the antenna terminal 2 is pressed by the terminal connecting portion 23 of the antenna holding member 2 and gradually bends. When the antenna holding member 2 is firmly screwed into the case 3 and the mounting is completed. Since the antenna contact portion 52 of the antenna terminal 5 abuts elastically on the terminal connection portion 23 of the antenna holder 2, the antenna terminal 5 is pressed against the case 3 and temporarily fixed (see FIG. 3).

Next, the printed circuit board 4 is mounted on the case 3. The printed board 4 is disposed with the surface of the land putter 41 facing the case 3, and is mounted on and abutted on the flat portion 34 and the rib 35 of the screw boss 32 of the case 3 to be positioned at a predetermined position. In this state, by attaching and fixing a cover (not shown) to the case 3, the printed circuit board 4 is sandwiched between the case 3 and the cover, and is fixed in the apparatus. At this time, as shown in FIG. 4, the substrate contact portion 51 of the antenna terminal 5 is pressed and bent by the printed circuit board 4 and comes into contact with the printed circuit board 4 with elasticity.
