Description

  The present invention relates to a clip fixing structure for fixing a clip to an electronic device such as a microphone and a portable wireless communication device.

  As a clip fixing structure for fixing the clip to an electronic device such as a microphone and a portable wireless communication device, for example, there is one shown in (Patent Document 1) of FIG. In this case, as shown in FIG. 7, the clip part 3 is inserted into the attachment portion 2 formed on the case surface 1 of the device.

  That is, the mounting portion 2 of the case surface 1 includes a concave portion 4 and a U-shaped locking portion 5. The locking portion 5 has an inverted L-shaped protrusion on the case surface 1 and a U-shaped opening. And a U-shaped groove for insertion between the case surface 1 and the case surface 1 (hereinafter referred to as a rail portion). On the other hand, the clip part 3 is a base 7 having slide insertion portions 6 formed on both sides, and is attached with a shaft 8 so that a hook 9 can be opened and closed, and urges the shaft 8 in a closing direction. A spring is inserted. Further, a tongue piece 10 is provided at the front portion of the base 7, and a hook-like locking piece 11 is provided at the tip of the tongue piece 10.

  Therefore, in such a fixing structure, as shown in FIG. 8, the base 7 of the clip part 3 to which the hook 9 is attached is inserted into the slides on both sides from the opening of the U-shaped rail portion 5 provided on the case surface 1. The part 6 is fitted into the rail parts 5 on both sides of the U-shape and is slid to fit. Then, the locking piece 11 provided on the tongue piece 10 fits into the concave portion 4 of the case surface 1 and fixes the clip part 3 as shown in FIG.

  However, in the fixing structure as described above, when the fixed clip part 3 is used as a clip, the clip part 3 is sandwiched between the case surface 1 and the stress corresponding to the sandwiching force (holding force) is applied to the case. In addition, the rail portion 5 formed on the case surface is always added and damaged. As a result, there is a problem that a (large) clip having a strong holding force cannot be attached.

  As one method for solving this problem, for example, it is conceivable to use a clip unit as in the embodiment of the present application shown in FIG.

  The clip unit 20 is attached so as to be openable and closable via a spring that biases the fixed plate member 21 and the movable clip member 22 in the closing direction. Thus, since it was made the structure provided with the clamping piece up and down, since it can clamp by only the clip unit 20, it can reduce the stress added to the case surface 1 and the rail part 5 of the case surface 1. FIG.

  By the way, the most conceivable fixing structure for attaching the clip unit 20 capable of reducing such stress to the case surface of the device or the case surface 1 is to screw it to the case body. The following two methods can be considered for this screwing.

  One is a method of fastening together with a screw 14 for fixing the rare (rear) panel 12 and the front panel 13 of the case body as shown in FIG. The other is a method of fixing using a screw 15 different from the fixing screw 14 of the case body as shown in FIG.
