A pair of elastic rotation angle limiting protrusions 55 are formed so as to protrude from the surface so as to face each other along the outer periphery of the outer peripheral edge of the output connector insertion hole 51. Further, a pair of arc-shaped projecting ribs 53a projecting from the back surface so as to face each other along the outer periphery of the outer peripheral edge of the output connector insertion hole 51 between the elongated groove and the rotation angle limiting projection 54, and A pair of arcuate protruding ribs 53b that protrude from the surface along the outer peripheral edge of the output connector insertion hole 51 are opposed to the outer side of the pair of protruding ribs 53a between the elongated groove and the rotation angle limiting projection 54. It is formed to do. Still further, a claw receiving portion 56 formed to protrude backward from the left and right side plates for engaging with the decorative terminal block 4 and a wall surface mounting portion 57 formed to protrude from the left and right side plates to both sides. have. The terminal mounting frame 5 may be made of an insulating material such as synthetic resin.

  The output connector insertion hole 51 is an insertion hole for inserting the output connector 12 of the terminal main body 1 provided at a substantially central portion of the bottom plate of the terminal mounting frame 5 as shown in FIG. A cutout portion 52 is provided so as to be connected. The inner diameter of the output connector insertion hole 51 is slightly larger than the outer diameter of the output connector 12.

  The notch 52 is provided so as to be connected to the output connector insertion hole 51 and allows the wing 13 provided in the output connector 12 to be inserted into the terminal mounting frame 5. The shape of the notch 52 may be any shape as long as the wing 13 can be inserted, and is preferably a rectangular shape that allows the wing 13 to be easily inserted. The number of notches 52 is also selected according to the number of wings 13, and the number of wings 13 may be one or more, and two or more are preferably provided. An elastic rotation angle limiting projection 55 described later is provided between the notch 52 and the elongated groove. Here, when the output connector 12 of the terminal body 1 is inserted through the output connector insertion hole 51, the wing part 13 is inserted into the pair of rectangular cutout parts 52, and the terminal body 1 is rotated, the side surface of the wing part 13 Comes into contact with the slope of the elastic rotation angle limiting projection 55 and the elastic rotation angle limiting projection 55 is pushed down as the terminal body 1 rotates, so that the wing 13 gets over the elastic rotation angle limiting projection 55. Become. Since both sides of the elastic rotation angle limiting projection 55 are formed as notches 52 and elongated grooves, the elastic rotation angle limiting projection 55 is elastically deformed.

  Protruding ribs 53a are provided on the rear surface of the bottom plate at the periphery of the output connector insertion hole 51, and protruding ribs 53b are provided on the surface of the bottom plate. When the terminal body 1 that is rotatably inserted into and fixed to the terminal mounting frame 5 is rotated, the protruding surface of the protruding rib 53 a is pressed against the front surface of the terminal body 1, and the protruding surface of the protruding rib 53 b is the wing portion 13. When the terminal body 1 after being attached to the terminal attachment frame 5 is rotated on the axis of the output connector 12, it is rotated while a frictional resistance is generated. At this time, since the projecting ribs 53a and 53b are provided so as not to overlap the front and back surfaces of the bottom plate of the terminal mounting frame 5 by shifting the installation position, the projecting ribs 53a are in contact with the front surface of the terminal body 1. On the other hand, the protruding rib 53b is floated by the height of the protruding rib 53a, and the bottom plate of the terminal mounting frame 5 bends when the wing 13 abuts on the protruding rib 53b, so that an appropriate frictional resistance is provided. 13 and the protruding rib 53b, and the force applied during assembly can be reduced. Therefore, the antenna terminal device of the present invention can obtain an appropriate frictional resistance when rotating without using an O-ring. Here, the structure of the protruding rib 53 is not particularly limited as long as the protruding rib 53b and the wing 13 are slid. For example, the output connector insertion hole 51 has a circular arc shape, a straight line shape, a hemispherical shape at the base periphery. It is good also as the protrusion rib 53 which consists of convex parts of the shape. Further, as shown in FIG. 10, the protruding ribs 53 a and 53 b are provided on the front surface and the back surface of the bottom plate of the terminal mounting frame 5.

Thus, a wedge-shaped protrusion structure is formed in which the rear end is a step portion of a steep slope. Since the end (the elongated groove side) of the elastic rotation angle limiting projection 55 is a stepped portion of a steep slope, the wing part 13 gets over the elastic rotation angle limiting projection 55 from the opposite side and returns to the notch 52. Is prevented, the rotation angle is limited, and the terminal body 1 is prevented from falling off from the terminal mounting frame 5. Here, when the terminal body 1 is rotated on the output connector shaft after the wing portion 13 is inserted into the notch portion 52, the wing portion 13 comes into contact with the inclined surface of the elastic rotation angle limiting projection 55 and rotates. When the wing 13 is pushed down and passes through the step portion of the steep slope at the end of the elastic rotation angle limiting projection 55, the elastic rotation angle limiting projection 55 returns to the original position (see FIG. 12). After the wing 13 passes through the step portion of the steep slope at the end of the elastic rotation angle limiting projection 55, the wing portion 13 comes into contact with the step portion of the steep slope when the terminal mounting frame 5 is rotated in the reverse direction. In addition to restricting the rotation of the output connector 12 on the axis, the wing 13 returns to the direction of the notch 52 and prevents the terminal body from dropping off. Thereby, the terminal body 1 can be rotated only between the rotation angle limiting projection 54 and the elastic rotation angle limiting projection 55. The shape of the elastic rotation angle limiting projection 55 may be any structure as long as it can limit the rotation angle after the wing portion 13 gets over the projection, prevent the terminal body 1 from returning, and prevent the drop off. Although not limited to this structure, it is preferable to use a curved surface that matches the sliding surface of the wing part 13 because the wing part 13 can easily get over.

By rotating the wing portion 13 on the output connector shaft, the elastic rotation angle limiting projection 55 provided on the terminal mounting frame 5 is pushed down to the die casting case 14 side of the terminal body 1, and the wing portion 13 is elastically rotated. When passing through the step portion of the steep slope at the end of the moving angle limiting projection 55, the elastic rotation angle limiting projection 55 returns to the original position before the terminal body 1 is connected (see FIG. 12). As a result, the terminal body 1 having the wing 13 can be rotated only between the rotation angle limiting projection 54 and the elastic rotation angle limiting projection 55 provided on the terminal mounting frame 5.
