を図る。The present invention is provided with an FBT holding claw for suppressing the forward movement of the FBT by an external impact force, a guide boss for suppressing the upward, downward, leftward, rightward and backward movements.
BT upper screw tightening boss outer diameter and guide boss inner diameter and FBT
The appropriate space provided between the holding claw and the FBT absorbs dimensional variations of components and assembly work variations, so that the FBT solder terminals can be placed on the printed circuit board without stress.
The purpose is to firmly hold BT. further,
The number of members required to hold the FBT is reduced and the workability of assembly is improved.

上がり、ＦＢＴとの嵌合が外れる。In order to achieve the above object, after the movable part and the fixed part of the FBT holding device are bent from the hinge part, a gap is provided between the movable part and the fixed part and the back cover, and the fitting mating claw is used. Attach it to the back cover. This clearance causes the movable part to bend in the direction opposite to the bending, and the FBT
The holding claws are open. In this state, move the back cover from the rear of the set and set the FBT upper screw tightening boss to F
Insert into the guide boss of the BT holding device. At this time, FB
An appropriate space is secured between the outer diameter of the T upper screw fastening boss and the inner diameter of the guide boss, and the FBT solder terminal is structured so that excessive stress is not applied. Next, in order to hold the FBT, the movable part is screwed to the screw tightening boss of the fixed part, thereby eliminating the gap X between the movable part and the fixed part.
Tighten the T-holding claw to the FBT upper screw tightening boss. By fitting the FBT holding claw on the upper part of the FBT where the amount of movement of the FBT due to the external impact force is the largest, the forward movement of the FBT can be suppressed and the FBT can be firmly held.
At the same time, FB is provided by the guide bosses provided on the movable part and the fixed part.
Because the T upper screw tightening boss can be held,
It also restrains the movement to the left and right and to the rear. To release the holding of the FBT, by loosening the screw, the movable portion bends in the direction opposite to the bending, so that a clearance is obtained, the FBT holding claw is lifted, and the fitting with the FBT is released.
