* Explanation of symbols for the main parts of the drawings

1: Keyboard 1a: Upper case

1b: lower case 2, 10: cord

3, 7: connector 4: groove-shaped recess

5: block part 6: jamming protrusion

8: code fixing protrusion 9: opening

The present invention relates to a holding structure of an external drawing code of a key board used in a personal computer, a word processor, or the like.

Conventional cord holding structures of such keyboards include Japanese Patent Application Laid-Open No. 61-12131.

6 and 7 are cross-sectional views taken along the line C-C of FIG. 6 and a bottom view of the keyboard showing the code holding structure of the keyboard.

As shown, the cord 10 drawn out from the inside of the keyboard 1 to the bottom center is guided to the side of the keyboard 1 by the U-shaped groove 11, and the cord 10 is U-shaped. The code 10 is prevented from falling out of the U-shaped groove by the code drop preventing projection 12 protruding inward from the front end of the magnetic groove 11.

However, in the above-described conventional example, there is provided a means for the code 10 to drop out of the U-shaped groove 11, that is, a means for suppressing the code 10 from moving in the vertical direction of the keyboard 1. There was no means for suppressing the movement of the cord 10 in the transverse direction of the keyboard 1.

Therefore, when the cord 10 is pulled in the horizontal direction, the cord 10 is deviated laterally, and the cord 10 is pulled out inside the keyboard 1.

On the contrary, when the cord 10 is pushed in from the side of the keyboard 1, the problem has arisen that the cord 10 is pushed into the inside of the keyboard 1.

Therefore, when the code | column 10 falls out from the connector (not shown) which connects the printed board (not shown) and the code | coin 10 inside the keyboard 1, or the connector falls out of a printed board. A defect such as this occurred.

It is an object of the present invention to provide a code holding structure of a keyboard which can eliminate the above-mentioned drawbacks of the prior art and can suppress the movement of the code not only in the vertical direction of the keyboard but also in the horizontal direction.

In order to achieve the above object, the present invention provides a keyboard having a top case and a bottom case, and installs a plurality of cord engaging protrusions to hang the cord on the upper surface of the lower case, and arranges the catching protrusions so that a part of the cord is bent at an acute angle. The bottom surface of the upper case is in contact with the upper portion of the cord and pressed down on the bottom surface of the lower case is provided that the fixing projection between the engaging projection.

The above technical means function as follows.

A portion of the cord is bent at acute angles between the plurality of locking projections that hang the cord on the upper case of the lower case to suppress the transverse movement of the cord, and the cord pressed between the lower case of the upper case and the upper case of the lower case It is also possible to suppress even movement in the up and down direction of the cord by the cord fixing protrusion for fixing the gap between the protrusions formed in the lower case.

EXAMPLE

Next, an embodiment of the present invention will be described with reference to the drawings of FIGS. 1 to 5.

In addition, the same code | symbol is attached | subjected to the component which has the same function as a prior art example, and detailed description is abbreviate | omitted.

In the figure, reference numeral 1 denotes a keyboard, which includes a case made of an upper case 1a and a lower case 1b.

In addition, the keyboard 1 is provided with a cord 2 for connecting to a main body (not shown) and a connector 3 mounted at an end thereof.

2 is a bottom view of the keyboard, and the cord 2 drawn out from the inside of the keyboard to the bottom is accommodated in the groove-shaped recess 4 of the bottom of the lower case 1b and drawn out to the side of the keyboard. .

FIG. 3 and FIG. 4 are top views of the lower case showing the inside of the keyboard, in particular, FIG. 4 is an enlarged view of the portion of FIG. 3 and (A), and the convex formed in the wall shape on the top of the lower case 1b. In the region surrounded by the section 5, a plurality of locking projections 6 are formed.

In addition, the cord 2 having the connector 7 connected to the printed circuit board at the front end is introduced into the area surrounded by the convex portion 5 at the bottom of the lower case, and at the same time between the plurality of engaging projections 6. It is wound in a zigzag shape to bend at an acute angle.

FIG. 5 is a bottom view of the upper case showing the inside of the keyboard, and the upper part of the cord 2 which is in contact with the upper part of the cord on the bottom of the upper case 1a and is wound between the engaging projections 6 on the upper surface of the lower case 1b. The cord fixing protrusion 8 which abuts on is formed.

Therefore, when the upper case 1a is attached to the lower case 1b, this cord fixed frame 8 abuts on the part indicated by (B) in FIG.

In other words, a plurality of locking projections 6 are disposed on the upper surface of the lower case so that the lower surface of the upper case 1a is in contact with the upper portion of the cord and the cord pressed on the lower surface of the lower case 1b is interposed between the protrusions 6. To be fixed in place.

As described above, the present invention is to install a plurality of cord locking projections to hang the cord on the upper surface of the lower case, and at the same time to fix the code pressed on the bottom of the lower case abuts on the bottom of the upper case between the locking projections on the bottom of the upper case Since the code fixing protrusions are disposed, it is possible to prevent the code from moving when the cord is tensioned or pushed in.

Claims (1)

In the keyboard 1 having an upper case 1a and a lower case 1b, a plurality of cord engaging protrusions 6 are provided on the upper surface of the lower case 1b, and a part of the cord is acute. Position the locking projection (6) to be bent and the cord fixed to contact the top of the cord to the bottom of the upper case (1a) and to press the cord pressed on the bottom of the lower case (1b) between the locking projection (6) A code holding structure for a keyboard, characterized in that a projection (8) is provided.
