An end portion of the jack holder 3 is inserted and clamped in the hole 5, and the other end portion is fastened and fixed to the boss 7 of the cabinet 4 by the screw 6 together with the main board 2.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a jack mounting device used in a cassette tape recorder and other electric devices.

[0002]

[Prior Art]

 An example of a conventional jack mounting device will be described with reference to FIG. A main board 9 and a jack 10 are connected and fixed to the main board 9 by soldering. The rear cabinet 11 has a hole 12 through which the jack 10 is exposed. Reference numeral 13 is a front cabinet provided with ribs 14. The rib 14 holds the jack 10 when the rear cabinet 11 and the front cabinet 13 are integrally joined.

[0003]

[Problems to be solved by the device]

 However, in the conventional jack mounting device as described above, when the jack 10 is arranged in the back of the rear cabinet 11, the rib 14 is required to be retained by the rib 14 of the front cabinet 13. It had to be very long, which made the front cabinet 13 difficult to mold. Further, since the rib 14 projects from the main body of the front cabinet 13, there is a possibility that the rib 14 may be broken due to vibration during transportation. Furthermore, since the ribs 14 are long and weak, when an external force is applied to the jack 10, the external force is also applied to the connecting and fixing portion by soldering the main board 9 and the jack 10, and the foil cracks and the main board 9 at this portion. There was a problem that cracks occurred.

Further, the amount of protrusion of the jack 10 from the hole 12 of the rear cabinet 11 to the outside is determined by how the main board 9 and the jack 10 are attached, so that a plurality of jacks are connected and fixed to the main board 9. In this case, there is also a problem that the variation becomes large. The object of the present invention is to solve the above problems, connect and fix a plurality of jacks to the main board, position them with a jack holder, and attach them to the cabinet together with the main board. An object of the present invention is to provide a jack mounting device which can prevent the main board from cracking and can keep the amount of the jack protruding from the jack holder constant.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention comprises a main board to which a plurality of jacks are connected and fixed by solder, a jack holder for positioning and fixing the jacks, and a cabinet having a hole for exposing the jacks to the outside. An end portion of the jack holder is inserted and held in the hole, and the other end portion is fastened together with the main board to a cabinet to be a fixed jack attachment device.

[0006]

[Action]

 According to the present invention, as described above, the jack holder is provided on the main board to which a plurality of jacks are connected and fixed, and the jacks are pre-positioned and fixed. Therefore, the amount of each jack protruding from the jack holder to the outside is constant. You can Also, since the end of the jack holder is inserted and pinched in the hole of the cabinet and the other end is fastened and fixed to the cabinet together with the main board, external force applied to the jack is prevented and soldering between the jack and the main board is performed. As a result, foil cracks and main board cracks did not occur in the connection and fixing parts.

[0007]

【Example】

 Hereinafter, a jack mounting apparatus as an embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a sectional view of the jack mounting device of this embodiment taken along the line AA in FIG. 2, where 1 is a jack, 2 is a main board, and 1 is a main board 2 connected to the main board 2 by soldering. It is fixed. 3 is a jack holder, which fixes and fixes the jack 1. A cabinet 4 has a hole 5 for exposing the jack 1 to the outside.

In this embodiment, the end portion of the jack holder 3 is inserted and pinched in the hole 5, and the other end portion is fastened and fixed to the boss 7 of the cabinet 4 with the screw 6 together with the main board 2. For this reason, the connection fixing portion by soldering the jack 1 and the main board 2 is always stable, and it is possible to prevent the connection fixing portion from peeling off even when an external force is applied to the jack 1.

In addition, in the example shown in FIG. 2, in addition to inserting and holding the jack holder 3 in the hole 5, ribs 8 and 8 are provided in the vicinity of the hole 5 of the cabinet 4 to hold the side surface of the jack holder 3. ing. FIG. 3 is a perspective view of the jack holder 3 and the cabinet 4. The end portion of the jack holder 3 is moved in the arrow direction to be inserted and clamped in the hole 5 of the cabinet 4, and the side surfaces of the jack holder are clamped by the ribs 8 and 8. ..

FIG. 4 is a front view of the jack holder 3, in which two jacks 1 are separated at the center, and the center portion is inserted and clamped in the hole 5 of the cabinet.

[0011]

[Effect of the device]

 As described above, according to the present invention, since a plurality of jacks are connected and fixed to the main board and the positions of the jacks are fixed by the jack holder, the amount of protrusion of each jack from the jack holder to the outside is fixed when the cabinet is mounted. You can now Also, the end of the jack holder is inserted and sandwiched in the hole provided in the cabinet, and the other end is clamped and fixed to the cabinet together with the main board. It was possible to provide a stable jack mounting device without any risk of occurrence of

Further, unlike the conventional case, there is no need to provide a rib for holding the jack in the front cabinet, and the structure is easy to mold and easy to use.
