Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a printed board with a cable fixing device that can fix a cable (including various wire materials) inside a telephone or the like by using a print board.

[0002]

[Prior art]

 Many cables are arranged inside a housing forming an electric or electronic product such as a telephone. In order to arrange these cables neatly inside the housing, it is necessary to use a cable fixing tool to prevent the cables from changing inside the housing. For this reason, conventionally, as shown in FIG. 3, a cutout 21 having a tongue portion 21a for holding a cable is formed in a printed board 20 incorporated in a housing so that a cable 22 is sandwiched via the tongue portion 21a. The fixing method (conventional example 1) or the cable insertion groove 23 is formed continuously from the plate end of the printed board 20 and fixed by inserting the cable 24 from the end of the printed board 20 into the cable insertion groove 23. Method (conventional example 2), or a cable holding groove 25 is formed at the end of the printed board 20, a cable 26 is positioned in the cable holding groove 25, and the cable 26 is held by the housing surface. A method of fixing so as not to come off from 25 (conventional example 3) is used.

Further, as shown in FIG. 4A, a method of fixing a plurality of pins 28 by arranging a plurality of pins 28 in a case 27 itself which forms a housing and inserting a cable 29 between the pins 28, and FIG. 4B. As shown, a method (prior art example 4) in which a rib 30 having a plurality of notches 30a is attached to the case 27 itself and the cable 29 is sandwiched between the notches 30a and fixed is used.

[0004]

[Problems to be solved by the device]

 However, in the above-mentioned conventional example 1, there is a fear that the tongue portion 21a for pinching the cable may be chipped, the cable is not sufficiently fixed, and the tongue portion 21a for pinching the cable and the cutout portion around the tongue portion 21a are not provided. Since a large space is occupied inside the board surface, there is a problem that the space for other mounted components is limited. Further, in the conventional example 2, since the cable insertion groove 23 is formed near the plate end of the printed board 20, the problem of space as in the conventional example 1 is improved, but the cable 24 comes off. There is also a fear that the disconnected cable 24 may be caught between the upper case and the lower case when the device is assembled. Further, in the conventional example 3, although the problem of occupying the board space is further improved, the case is assembled while holding the cable 26, and the assembly work is performed while avoiding the cable 26 being caught on the switch or the like. Therefore, the work was complicated. Further, in Conventional Example 4, when the cable 29 is formed narrow between the pins 28 and the notch 30a of the rib 30 so that the cable 29 is easily detached, while the cable 29 is not easily detached, the cable 29 is notched between the pins 28 and the rib 30. There is a problem that it is not possible to smoothly perform the work of being sandwiched between.

The present invention has been proposed to solve the above problems, and it is an object of the present invention to provide a printed board with a cable fixture that can easily fix a cable and can maintain a stable fixed state. It is intended.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides a printed board with a cable fixture, which is arranged and fixed in a case and is provided with various circuit parts, cables, etc., from the board end of the printed board to the screw hole for fixing the printed board. A printed board with a cable fixing tool, in which a groove for a cable guide is formed, and a groove for fixing the cable is continuously formed from the screw hole for fixing the printed board. Further, the printed board has a cable fixing tool in which the cable guide groove, the printed board fixing screw hole, and the cable fixing groove are continuously formed in a straight line in the printed board surface. Further, the printed board with a cable fixing tool is formed by continuously forming the cable fixing groove with respect to the cable guide groove at a required angle within the surface of the printed board.

[0007]

[Action]

 In this way, the cable guide groove, printed board fixing screw hole, and cable fixing groove are formed continuously, so the cable can be pulled into the cable fixing groove and the cable can be easily fixed at the same time as the print plate is fixed. At the same time, a stable fixed state can be maintained.

[0008]

【Example】

 Hereinafter, embodiments will be described with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of the present invention. As shown in the figure, a first printed board 2 is arranged inside a case 1 forming a housing, and a second printed board 3 is provided therein with a screw 4a and a screw receiver 5a fixed to the case 1, Further, it is fixed by the screw 4b and the screw receiver 5b. In this embodiment, the fixing of the cable 7 of the microphone unit 6 attached to the housing will be described as an example.

A hole 8 for inserting the screw 4a is formed in the second printed board 3, and a cable guide groove 9a and a cable fixing groove 9b are formed so as to be continuous with the hole 8. . One cable guide groove 9a is formed from the plate end of the printed board 2, and the other cable fixing groove 9b is continuously formed on the extension line of the cable guide groove 9a via the hole 8. There is. Further, the cable fixing groove 9b formed through the hole 8 is not limited to the extension of the cable guiding groove 9a, and is not limited to the cable guiding groove 9a within the plane of the printed board. You may form in a direction. FIG. 2 shows a modification in which the cable fixing groove 9b is formed in a direction perpendicular to the cable guiding groove 9a. This is to properly and reasonably attach and fix the cable to the printed circuit board under different cable attachment conditions. Needless to say, no other groove is formed in the hole 10 into which the screw 4b that does not need to fix the cable is inserted.

With this configuration, in order to fix the cable 7 of the microphone unit 6, first, before fixing the second printed board 3 to the case 1, insert the cable 7 from the cable guiding groove 9a. After moving to the cable fixing groove 9b and adjusting the mounting posture of the cable 7, the second printed board 3 is screwed into the screw receivers 5a and 5b with the screws 4a and 4b to fix each member to the case 1. To do. It goes without saying that the same applies when fixing other cables not shown.

[0011]

[Effect of device]

 As described above, according to the present invention, the cable guide groove is formed from the plate end of the printed board to the printed board fixing screw hole, and the cable fixing groove is continuously formed from the printed board fixing screw hole. The cable can be fixed at the same time by pulling it into the cable fixing groove and screwing the print plate to the case. Therefore, it is possible to eliminate the disadvantage that the space for the plate surface is required because two or more notches for fixing the cable are provided and fixed or the cable is temporarily fixed as in the past. Moreover, the stable fixed state of the cable can be maintained. Also, no separate parts are needed to secure the cable. Also, since the cable is pulled into the board surface rather than the board end of the printed board, the cable is not caught between the printed boards and the assembly work can be performed efficiently. In addition, the cable guide groove, the printed board fixing screw hole, and the cable fixing groove are continuously formed in a straight line in the surface of the print board, so that the groove can be easily formed and the cable is fixed to the cable. The work of pulling it into the work groove can be done easily. Also, since the cable fixing groove is formed continuously with respect to the cable guide groove at the required angle within the printed board surface, pull the cable into the cable fixing groove that is formed according to the cable installation conditions. You can fix the cable comfortably.
