Is the same as that shown in. The connector section 203 includes connectors 203a, 203 to which the cords 201, 202 are connected.
b. The groove portions 204 and 205 are cords 20 respectively.
1, 202 for holding.

A plurality of sets of cord holding pieces 206 facing the both side walls of the groove portions 204 and 205 are the cords 20.
1, 202 are held in the groove portions 204 and 205, and the groove portion 20
This is to prevent the 4,205 from falling off. The cord holding piece 206 is provided so as to project from the groove portions 204 and 205. Two cord holding pieces 20 facing each other
Six gaps S are provided, and the width T of the groove portions 204 and 205 is slightly larger than the width L of the major axis of the cord.

The groove portion 204 is straight, and the groove portion 205 is L-shaped, but the shapes of both grooves are different, but the structure relating to attachment / detachment / holding of the cord is the same, so the following description will be made only for the groove portion 204. As can be seen from FIGS. 15, 16 (a) and 16 (b), the cord 201 is pushed into the groove portion 204 with almost no gap.

Conventionally, as shown in FIG. 16 (b), the groove portion 204 provided on the bottom surface of the telephone body has a width T having a length substantially the same as the thickness L of the cord 206 in the major axis direction, and holds the cord. The depth from the rear surface 211 of the piece 206 to the groove bottom surface 212 is formed to be substantially the same as the thickness e of the cord in the minor axis direction. With such a structure, the cord 201 is hard to rotate inside the groove portion 204. Then, in order to insert the cord 201 into the groove portion 204, the cord 201 is applied with a strong force from the gap S between the two opposing cord holding pieces 206 by utilizing the plastic deformation of the cord itself (see the figure). 16 (b) arrow B direction). Once pushed, since the thickness L in the major axis direction of the cord is larger than the gap S, the cord 201 is held in the groove portion 204. Also, by pulling the cord upward in the direction vertical to the bottom surface of the telephone body (direction opposite to the arrow B direction), the cord is pulled out from the gap S, and the cord 20
1 was detached and removed from the groove.

It is characterized by having.

In the groove, the depth from the surface of the cord holding piece facing the groove bottom to the groove bottom is deeper than the height of the modular jack, and the width of the groove is wider than the width of the modular jack. desirable.

It is also desirable that the cord holding piece has a tapered portion.

A second aspect of the invention is a cord attaching / detaching structure in an electronic device having a groove portion for inserting and holding a cord, wherein the groove bottom surface has an interval of a major axis of the cord in the groove width direction. One or more pairs of holes with holes are drilled, and the elongated cord holding plate that can be attached to and detached from the groove has a locking leg that can hold the cord and can be locked in the hole. The legs are characterized by having flexible parts.

[0014]

With the above structure, the cord can be easily inserted into the groove by pressing the cord against the cord holding piece by utilizing the bending of the cord holding piece instead of utilizing the deformation of the cord. Also, when removing the cord with the modular jack from the groove, it is sufficient to simply pull it out through the groove.
