Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is incorporated into a substrate made by integrally molding a resin onto a metal plate (hereinafter referred to as outsert molding).
Figure 2 shows a locking device used in a conventional digital audio diffuser player during transportation. Figure 1 A, B
, 1 is an optical pickup, 1a is a protruding piece thereof, 2
is a base into which the optical pickup 1 is installed, 3 is a guide shaft that supports the optical pickup 1, 4 is a housing, and 6 is a housing 4 during transportation.
The locking material 6 inserted into the elongated hole 4a is movably held by the arms 4b, 4b of the housing 4, and has a screw 6 at the tip.
A is a lock member, and 7 is a spring.

The operation of the conventional locking device configured as described above will be described below.

In FIG. 1, during transportation, a b-tuck material 6 is inserted from the outside of the casing 4 through a long hole 4a made in the casing 4, and is fixed between the Hikari Pino Quag 10 and its protruding piece 1a. The optical pickup 1o is fixed and released by pulling out the locking material 6 from the elongated hole 4a.

In addition, in f, Figure 1B, the screw 6a was grouted at the tip. The optical pickup 1 is fixed by rotating the locking material 6 from the outside of the housing 4 with a lever or the like and tightening the screw 6a to a part of the optical pickup 1o. - This is done by removing the optical big ag 1 with the force of the spring 7.

However, in such a conventional configuration, the opening material 6
, 6 and spring 7 are separate parts, increasing the number of parts. Also, in the example shown in Fig. 1A, the locking material 6 is not built-in, making it difficult to store the parts until they are locked during re-transportation. , had the problem of being lost.

OBJECT OF THE INVENTION The present invention solves these conventional problems, and provides a locking device that does not require an increase in the number of parts and eliminates problems such as loss by incorporating the parts into the device. The purpose is to

Structure of the Invention The present invention uses a base plate made by outsert molding a resin on a metal plate as a base into which parts to be locked are assembled, and a clamp member which is outsert molded so that one end becomes a free end is also outsert molded. By rotating the locked locking member, the clamping member is swung out around a certain fulcrum and the parts to be locked are sandwiched and locked, and only members that are outsert molded on the same metal plate are used. This allows locking during transportation without increasing the number of parts.

DESCRIPTION OF THE EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 2 to 6.

In FIGS. 2 to 6, parts having the same functions as those in FIG. 1 are denoted by the same reference numerals, and explanations thereof will be omitted.

Reference numeral 8 denotes a metal plate substrate, 9 a clamp member formed by outsert molding on the substrate 8, and 10 a locking member also formed by outsert molding on the substrate 8, as shown in FIG. 3A.

As shown in B, the boss 11 on the back side is inserted through the round hole of the board 8.
It is integrated with. Center of locking member 10 and boss 11
The locking member 10 and the boss 11 constitute an eccentric shaft. Further, the tip of the boss 11 has a slot in the shape of a Phillips-head so that it can be hit with a screwdriver. Then, as shown in FIG.
Extend a part of the tip yjM part to the vicinity of the housing 4, and
2 is formed. Further, in order to make the protrusion 12 more visible, a small hemispherical protrusion 13 is provided at the tip of the protrusion 12. Then, as shown in FIG. 6, a [LockJ "Fre.
e The letter J and arrow 14 are stamped.

The operation of the locking device of this embodiment configured as described above will be described below.

First, from the state shown in FIG. 3A, the boss 11 is rotated using a screwdriver. Then, the locking member 1o is swung by the eccentricity with respect to the boss 11, and the clamping member 9 is moved to a position where the optical pickup 1 is sandwiched therebetween, as shown in FIG. A stopper (not shown) is attached to the post 11 side of the board 8 to prevent the boss 11 from rotating beyond this position, and to release the zero lock in which the optical pickup 1 is locked at this position, Rotate the boss 11 in the opposite direction. Then, the lock part 10 returns to its original position, and the clamp member 9 returns to its original position by its own elasticity.
The lock will be released. At this time, in case the clamp member 9 does not return completely by its own elasticity, a part of the clamp member 9 is extended and the lock member 1 is rotated to the release position.
A return member 9a is added to a part of the clamp member 9 so as to forcibly return the clamp member 9 at the outer periphery of the clamp member 9.

In addition, in order to be able to determine from the outside whether the current state is a locked state or a free state, a part of the tip of the boss 11 is extended to form a protrusion 12 as shown in FIG. It would be more convenient if r LockJ and r FreeJ were engraved on the outside of the casing 4 in correspondence with the +itl protrusions 12 shown in FIG. In the example of FIG. 6, the protrusion 12
is located at [LockJ, indicating that the optical pickup 1 is currently locked. When the lock is released, the protrusion 12 is engraved [It goes without saying that it will be attached to the FreeJ.0 If you do the above, the lock members 5 and 6 and the spring 7 as shown in Figure 1 will be prepared as separate parts. A built-in locking device can be obtained without increasing the number of parts.

Effects of the Invention The present invention incorporates parts to be locked into a board formed by outsert molding, and provides a shift lamp member on the board by outsert molding, thereby achieving a built-in method without increasing the number of parts. This realizes an excellent locking device.
