When such an external antenna connector 51 is locked to the mounting plate 41, as shown in FIGS. 1 and 2, the projections 55a, 5a of the small-diameter portion 54 of the connector 51 are used.
The small diameter portion 54 of the connector 51 is inserted into the insertion hole 43 of the mounting plate 41 with the 5b aligned with the grooves 42a and 42b of the insertion hole 43, and the distal end side of the small diameter portion 54 of the connector 51 and the projection 55a. , 55b are positioned inside the mounting plate 41. At this time, the protrusions 55a and 55b are
b, the distal end side of the small-diameter portion 54 of the connector 51 having the protrusions 55a and 55b is inserted into the insertion hole 43.
And can be positioned inside the mounting plate 41. At this time, the step 52 at the middle of the connector 51
Abuts against the outer surface of the mounting plate 41, so that the connector 51 stops with only the small-diameter portion 54 of the connector 51 inserted into the insertion hole 43. Thereafter, the connector 51 is rotated 90 ° as shown in FIG. Then, the protrusions 55 a and 55 b at the tip of the small diameter portion 54 of the connector 51 are inserted into the grooves 42 of the insertion hole 43.
The connector 51 is shifted from the portions a and 42b to the inner surface of the mounting plate 41 and is hooked on the inner surface of the mounting plate 41. As a result, the connector 51 is locked to the mounting plate 41. Thereafter, when the connector 51 is turned back by 90 °, the protrusion 55 is again returned as shown in FIG.
Since a and 55b match the grooves 42a and 42b, the distal end of the small-diameter portion 54 and the projections 55a and 55b of the connector 51 can be pulled out from the insertion hole 43, and the connector 51 can be removed from the mounting plate 41.

As shown in FIG. 1, a first projection 44 is provided on the inner surface of the mounting plate 41. This first projection 44
Is provided such that when the connector 51 is rotated by 90 ° in the direction of arrow A in FIG. 2, the protrusion 55b on the other side comes into contact as shown in FIG. Therefore, by providing the first projection 44, the connector 51 is accurately stopped at a predetermined position rotated by 90 °, and the connector 51 is attached to the mounting plate 41.
Can be securely locked, and the direction of the cable 61 can also be specified. Here, assuming that the connector 51 rotates in the direction opposite to the arrow A from the state of FIG. 2, the one protrusion 55 a contacts the first protrusion 44 in a state where the connector 51 does not rotate 90 °, and the connector 51 is rotated. It stops. Therefore, it is preferable to combine the regulation of the rotation direction with the second projection 45 and the inhibition of the rotation with the first projection 44.

As shown in FIG. 1, a protrusion 46 is provided on the inner surface of the mounting plate 41 in a bar shape. This raised portion 46
When the connector 51 is rotated by 90 ° in the direction of the arrow A in FIG. 2, the protrusion 55a on one side abuts, the protrusion 55a gets over, and the connector 51 is rotated by 90 ° as shown in FIG. 3. The connector 51 is provided in front of the protrusion 55a so as to function as a stopper for preventing the connector 51 from returning. Therefore, this raised portion 46
By preventing the connector 51 from returning, the connector 51 can be securely locked to the mounting plate 41 and the direction of the cable 61 can be specified.

Here, as shown by t1 and t2 in FIG. 4, the thickness of the pair of projections 55a and 55b can be changed to optimize the extent to which one of the projections 55a abuts on the raised portion 46. . That is, when the protrusion 55a on one side comes into contact with the protrusion 46, the rotation of the connector 51 stops, and when the connector 51 is rotated strongly, the protrusion 55a rides over the protrusion 46 and the connector 51 rotates again, and the connector 51 is rotated. 90 °
Although it is in a rotated state, how much force should be applied to the connector 51 when the protrusion 55a comes into contact with the protrusion 46 is determined by the amount of contact between the protrusion 55a and the protrusion 46. This contact amount can be set to an optimum value by changing the thickness of the pair of protrusions 55a and 55b.

Also, as shown in FIG. 5, if the inside of the projection 55a is a slope 551 and the slope 551 contacts the raised portion 46 of FIG. The rotational force required for the connector 51 when the 55a climbs over the raised portion 46 can be reduced, and at the same time, the vertical side surface 552 of the projection 55a comes into contact with the raised portion 46 at the time of reversing, so that the reversing can be surely performed. Thus, the connector 51 can be securely locked at a position rotated by 90 °, and the direction of the cable 61 can be designated.
