Description

[Detailed Description of the Invention] (Technical Field of the Invention) The present invention relates to a protective structure for a connecting cord, and more specifically, the present invention relates to a cord protection structure for a cord housing part suitable for an acoustically coupled terminal used in an answering machine system, etc. It's about structure.

(Prior art) In recent years, answering machine systems in which an acoustically coupled terminal is connected to a telephone transmitter and the recorded contents are listened to by transmitting an acoustic signal through the telephone line through the transmitter by dialing, and mobile phone Data entry systems and the like that transmit various data from terminals to telephone lines are widely used.

FIG. 1 is a perspective view showing a conventional acoustic coupling terminal used for this type of application, in which 1 is the terminal body, 2 is an acoustic coupling section formed of an elastic body such as rubber, and 3 is a push button. The dial part 4 is a connection code. The figure shows a terminal in which the acoustic coupling section 2 is configured separately from the terminal main body 1, and a spiral connection cord 4 is connected to the terminal.
The terminal device 1 is operated by connecting it to a handset (not shown), but when carrying the terminal device, not only does the combined size become large, but there is no housing for the connection cord 4, so it is difficult to carry the terminal device. It was very inconvenient to use. Furthermore, since there is no housing for the connection cord, there is a problem in that the cable may break due to bending stress during carrying.

(Purpose of the invention) The present invention solves the drawbacks of conventional terminals, and when carried, the acoustic coupling part and the push button dial part are integrated, and the connection cord is housed inside, so that no external force is applied. A cord protection structure in a connection cord housing part for realizing an acoustic coupling terminal in which the acoustic coupling part and the push button dial part are formed as separate bodies by pulling out the connection cord during operation. It provides:

15 is a mounting band used when attaching a handset (not shown) to the acoustic coupling part 12, 15 is a case A that serves as an assembly base for the terminal body, 15a is a receiving part of the acoustic transducer, and 15b is a mounting band on the circumference of the receiving part 15a. A ring-shaped convex portion is formed and serves as a rotation guide when housing the connecting cord 13 while rotating the reels A and B, 15c is a groove, and 16 is a ring that is housed in the case A15 and houses an acoustic transducer therein. Reel A (rotating body) is housed so as to be rotatable along a shaped convex portion 15b, 16a is a fitting recess into which the fitting protrusion of reel B is inserted, and 16b is a cord protection member 20.
The acoustic transducer 1
7 is engaged and fixed when accommodated in the holding portion 16d. 16d is a holding part that holds the acoustic transducer 17; 17 is the acoustic transducer accommodated in the reel A16; 17a is a connection terminal for the acoustic transducer 17;
8 is a reel B that is fitted into the reel A16 and becomes an integral part; 18a is a fitting protrusion that is inserted and fitted into the fitting recess 16b of the reel A16; and 18b is a recess formed on the operation surface side of the reel B18 to press the finger. This is to rotate reels A and B by hitting the ball. 18c is the flange of reel B18, 18d is a convex portion that clamps the cord protection member 20 with the peripheral wall of reel A16 when it is fitted to reel A16, and 19 is the flange of reel A1 on case A15.
6. Case B, 19a fitted into case A15 with acoustic transducer 17 and reel B18 installed
is an engaging pawl that engages with the groove 15c of the case A15. Reference numeral 20 denotes a cord protection member made of a rubber member or the like, which is engaged and held in the engagement recess 16c of the reel A16, pressed from above by the protrusion 18c of the reel B18, and held between the reel A16 and the reel B18. . 20a-1 and 20a-2 are the engagement recesses 1 of the reel A16 when engaged with the reel A16.
Both ends of 6b are the clamping parts into which they are inserted. This cord protection member 20 includes an intermediate portion 20b accommodated in the engagement recess 16b and peripheral edges 16b-1, 16b- of the reel A16 located at both ends of the engagement recess 16b.
A pair of clamping parts 20a-1 that clamp 2, respectively.
20a-2, one of the pair of clamping parts 20a-1 faces from the inner wall side of the reel A16 to the intermediate part 20b, and the other of the pair of clamping parts 20a
-2, from the outer wall side of the reel A16 to the intermediate portion 20b
It constitutes a holding and fixing guide part in which the connection cord 13 is held and fixed in a state where it is arranged so as to face.

The installation procedure will be explained with reference to the exploded configuration diagram in FIG. 3 and the configuration diagram in FIG. 4. The acoustic transducer 17 is inserted into the inside of the reel A16, held by the holding part 16d and the engaging claw 16c, and the cord protection member 20 attached to a predetermined position of the connection cord 13 connected to the connection terminal 17a is attached to the reel. A16 engagement recess 16b
At the same time, the clamping parts 20a-1, 20a-
2 is both ends 16 of the engagement recess 16b of the reel A16
The entire protection member 20 is held by sandwiching b-1 and 16b-2. The reel A16 with the acoustic transducer 17 housed inside and the cord protection member 20 held in the engagement recess 16b is moved along the ring-shaped guide protrusion 15b formed on the circumference of the receiving part 15a of the case A15. Stored so that it can be rotated.
Next, attach the fitting protrusion 18a of the reel B18 to the reel A.
16 into the fitting recesses 16a and integrated. At the same time, the cord protection member 20, which is engaged with the engagement recess 16b of the reel A16, is clamped and held from above by the collar 18c of the reel B18. Finally, case A15 has reel A16, acoustic transducer 17,
By fitting the case B19 with the reel B18 installed, the case A15 and the case B19 are fixed by the engaging claw 19a and the groove 15c. At the same time, press the flange 18c of the reel B18 from above,
This prevents the reel B18 from coming off.

In the cord housing structure of the acoustically coupled terminal configured as described above, the case A15 has a base and a reel A16 that engages and houses the acoustic transducer 17, and a reel A16 that fits into the reel A16 and is formed on the operation surface side. A reel B18 having a concave portion is fitted together and a case B19 is fixed to the case A15 to form a cord accommodating portion, and the operation surface side of the reel B18 is exposed to the surface of the terminal to expose the recess on the operation surface. By pressing your finger on 18b and rotating it, reel A16, acoustic transducer 17, reel B1
8 are rotated as one body, and the connection cord 13 is wound around the peripheral wall of the reel A16 while being rotated and housed therein. Further, it is an outlet for the connection cord 13 connected to the connection terminal 17a of the acoustic transducer 17. Since bending stress due to the rotation of the reel A16 is most likely to be applied to the engagement recess 16b of the reel A16, the engagement recess 16b is formed into an arc shape so that it can be engaged along the peripheral wall of the reel A16. A pair of clamping parts 20a-1, 20 that clamp both ends 16b-1, 16b-2 of the
If a cord holding member 20 having a shape in which each of a-2 is extended to a predetermined length and a cord lead-out portion of one end 20a-2 is further extended is used,
It is completely unaffected by bending stress caused by rotation of the reel A16, and furthermore, external force on the connection terminal 17a of the acoustic transducer 17 can be prevented.

(Effect of the invention) As described above, according to the invention, when the connection cord 13 is pulled out from the terminal part 17a, the protection member 20 is attached to both ends 20a-1 and 20a-2 of the cord fixing part 20b, respectively. by extending both sides 16b- of the engaging recess 16b of the reel A16.
1 and 16b-2 are held in place, and the cord outlet part at one end is further extended, so the cord outlet part is strong against external bending stress, has a simple structure, and is small in size. It becomes a protective member. Therefore, when used in a connection cord accommodating portion of an acoustic coupling terminal or the like, it has an excellent effect of reliably preventing bending stress applied to the connection cord.
