Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an earphone storage device that can be used in audio equipment such as radio receivers, tape recorders, and radio equipment.

Conventional configurations and their problems In recent years, as devices have been required to be smaller, lighter, and more portable, the handling of earphones and earphone cords has become a serious problem when devices are carried around. . In other words, when carrying a device in a pocket of clothing, the cord of the earphone is rolled up and placed in the pocket at the same time, or the cord is wrapped around the device and the device is placed in the pocket. However, if the earphones are used under these conditions, the cords may become knotted or put under abnormal stress, which can easily lead to defects such as breakage of the earphone cords, and the risk of losing the earphones. I had a problem.

Purpose of the invention The present invention solves the above-mentioned conventional problems.
To provide an earphone storage device that allows earphones and their cords to be easily taken in and out of a device body.

Structure of the Invention In order to achieve the above object, the earphone storage device of the present invention includes an earphone with a cord, an earphone storage section, a cord winding reel biased in the winding direction of the earphone cord, and a cord winding reel that is biased in the winding direction of the earphone cord. A rotatable cord connecting terminal consisting of a concentric circular terminal centered around the rotation axis of the take-up reel and a pressure contact terminal that contacts the concentric circular terminal, and a locking claw formed on the cord winding reel. , a releasably locking plate biased in the direction of engagement with the locking pawl, and a knob for operating the locking plate, which allows the earphones and cord to be easily attached to the main body of the device. It has the advantage of being able to be stored in a large area and easily pulled out for use.

DESCRIPTION OF EMBODIMENTS FIG. 1 is a perspective view of a radio receiver using an embodiment of the present invention, FIG. 2 is a front view thereof, FIG. 3 is an enlarged sectional view taken along the line A-A in FIG. The figure is a back view. Here, 1 is a front cabinet of the radio receiver, 2 is a rear cabinet, 3 is an earphone storage section formed by the front cabinet 1 and the rear cabinet 2, 4 is an earphone, and 5 is a cord for the earphone 4. Reference numeral 32 denotes a reel portion, which has a reel body 6 and a reel lid 7 made of resin, and the reel lid 7 is fitted onto the reel body 6 and fixed by a claw 8 formed integrally with the reel body 6. 9 is a boss formed on the front cabinet 1, and 10 is a reel shaft, which is fixed by a protrusion 11 formed on the boss 9 so as not to rotate. A spiral spring 12 has one end fixed to the reel shaft 10 in a groove 13 and the other end fixed to the reel body 6. 14
1 is a printed wiring board, and concentric terminals 15 and 16 with a boss 9 at the center are formed of copper foil. 17 and 18 are pressure contact terminals welded and fixed to the reel body 6 so as to correspond to the circular terminals 15 and 16, and are configured so that they are always pressed against the concentric circular terminals 15 and 16 even when the reel body 6 rotates. has been done. The tip of the cord 5 is fixed to pressure contact terminals 17 and 18 by soldering. 19 is a screw.
20 is a locking pawl formed integrally with the reel body 6;
21 is a locking plate whose groove 22 engages with a rib 23 formed on the front cabinet 1 and is slidably attached. 24 is a compression coil spring attached between a rib 25 provided on the front cabinet 1 and the locking plate 21. 26 is a knob,
It is slidably fitted into the cabinet 1 by an integrally formed pawl 27, and abuts against the locking plate 21 so as to operate the locking plate 21. 28 is a lid of the earphone storage section, which is slidably fitted.
This lid 28 is provided with a groove 29 that serves as an outlet for the cord 5. 30 is a volume knob, and 31 is a tuning knob, which are configured to drive the variable capacitor and dial pointer 37 by rope drive.

Here, to explain the assembly procedure, first, the reel unit 32 connects the pressure contact terminals 17 and 18 to the reel body 6.
Next, the reel shaft 10 is inserted, and then one end of the spring spring 12 is fixed to the reel shaft 10 and the other end is fixed to the reel body 6, and then the lid 13 is fixed.
Insert. Next, connect the tip of cord 5 to pressure terminal 1.
7 and 18 by soldering, then attach code 5.
Prepare it by winding it onto a reel. Next, the locking plate 21 is inserted into the front cabinet 1, the compression coil spring 24 is assembled, and the knob 26 is fitted.
Next, the reel portion 32 prepared earlier is fitted onto the boss 9. At this time, the reel shaft 10 is rotated several times to bias it in advance. Next, the printed wiring board 14
Attach and secure with screw 19. Next, the rear cabinet 2 is attached, the earphones 4 are stored, and the lid 28 is fitted.

The operation of the earphone storage device of this embodiment configured as described above will be described below. First, the reel portion 32 is always urged in the direction a by the spiral spring 12, and the cord 5 is wound up. At this time, the locking plate 21 is urged in the direction c by the compression coil spring 24 and is engaged with the locking pawl 20 of the reel body 6. In this state, open the lid 28,
When you hold the earphone 4 and pull it out, the reel part 32 rotates in the d direction against the biasing force of the spring spring 12, and the locking plate 21 moves in the b direction over the locking pawl 20, and when it crosses over the locking plate 21, it engages again. It engages with the pawl 20. In this way, the length of the earphone cord 5 can be set freely. When storing the earbud 4, operate the knob 26 in the b direction to move the locking plate 21 in the b direction and release the engagement with the locking pawl 20. rotates in the direction a, the cord 5 can be wound up, and the earphone 4 can be stored in the earphone storage section 3.

As described above, according to this embodiment, the cord 5 is wound around the reel portion 32 that is biased in the direction a, and the cord 5 is secured by locking the locking plate 21 and the locking pawl 20 at any position. You can freely set the length, and the earphone 4
Earphones can be easily stored inside the cabinet when not in use.

Effects of the Invention As is clear from the above description, according to the present invention, an earphone with a cord, an earphone storage section, a cord winding reel biased in the winding direction, and a cord winding reel rotating shaft are provided. A rotatable cord connecting terminal composed of a central concentric terminal and a pressure contact terminal corresponding to the concentric terminal, a locking claw formed on a cord winding reel, and a locking claw that engages with the locking claw. Equipped with a locking plate that is biased in a direction that can be released and a knob that operates the locking plate, the earphones can be easily stored in the device, and the length of the earphone cord can be freely set and used. You can get excellent results.
