Description

[Detailed Description of the Invention] Technical Field of the Invention The present invention relates to a jack board on which a plurality of jacks are arranged.

PRIOR ART AND PROBLEMS When changing connections in audio recording and reproducing devices, various electronic devices, etc., or when connecting to microphones, a jack board with a plurality of jacks arranged thereon is provided. The jack and the plug inserted into the jack generally have a configuration specified by, for example, broadcasting technology standards.
The contacts open and close when the plug is inserted. For example, as shown in FIG. 1, insert the sleeve 3 of the jack 2 into a hole formed in the insulating substrate 1, and insert the sleeve 3 into the base of the sleeve 3 (the part that protrudes perpendicularly to the drawing and is not shown). ) is fixed to the back of the board 1 with screws or the like. Note that 4 is a frame, 5 is a ring spring, 6 is a tip spring, 7, 8
9 is a contact, 9 is an insulating spring bushing, 10 is an insulating plate, 11a to 11e are terminals, and 12 is a tightening screw.

In this jack 2, the terminals 11a to 11e are insulated from each other by an insulating plate 10, and the terminal 11e is connected to the frame 4 by a tightening screw 12 to serve as a ground terminal. Furthermore, by inserting the plug through the hole in the sleeve 3, the ring spring 5 and the tip spring 6 are moved and the contacts 7 and 8 are opened.
d is opened, and the ring spring 5 and the tip spring 6 come into contact with the contact piece of the plug, thereby establishing a connection between the conductive wires connected to the terminals 11b and 11d and the cord of the plug.

In such a jack board, even if plugs are inserted repeatedly, poor contact will occur within a relatively short period of time, for example, about one year, and only the jack with poor contact will be replaced.
However, since the conductive wires are connected to the terminals 11a to 11e by soldering and are on the back side of the board 1, it is not easy to remove the conductive wires from the terminals 11a to 11e, and it is also difficult to remove the jack 2 from the board 1. It was not easy. Therefore, there was a drawback that it was not easy to replace a defective jack.

Purpose of the invention The purpose of the invention is to protect the jack and to facilitate the replacement of a jack with poor contact. Examples will be described in detail below.

Embodiment of the invention FIG. 2 is a partially sectional side view of an embodiment of the invention, in which the jack 2 has the same structure as the jack shown in FIG. If the jack 2 is shown in a front view, FIG. 2 is a side view. Further, 4a is a mounting part integral with the frame 4, 21 is an insulator mounting board, 22 is a front plate of an insulating plate, 23 is a holding plate, 2
4 is a socket, 25 is a fixing metal fitting, and 26, 27 are screws, and the same reference numerals as in the other figures in FIG. 1 indicate the same parts. The holding plate 23 is fixed to the mounting board 21 with screws 27, the socket 24 is fixed to the fixing metal fitting 25, and the fixing fitting 25 is fixed to the holding plate 23 with screws 26.

Connect terminals 11a to 11 of jack 2 to socket 24.
e, insert the sleeve 3 of the jack 2 into the hole of the front plate 22, sandwich the mounting part 4a of the jack 2 between the front plate 22 and the mounting board 21, and then
By fixing the front plate 22 with screws etc.,
The jack 2 is inserted into the socket 24 and fixed. Therefore, the jack 2 is placed in the space formed between the holding plate 23 and the mounting board 21, and this space is surrounded by the holding plate 23, the fixture 25, the socket 24, and the mounting board 21. In this way, the jack 2 can be protected from the outside. The terminal of socket 2 is used to connect the conductor wire to the terminal of a conventional jack by soldering, etc., and by simply inserting jack 2 into socket 24, a connection with the desired circuit is established. .

When replacing a jack with poor contact, etc., remove the front plate 22, pull out the jack 2 from the socket 24, and then insert the new jack into the socket 24.
It can be easily replaced by inserting the front plate into the front plate and attaching the front plate 22.

In FIG. 3, a is a top view of the mounting board 21, and b is a side view, showing a square hole 30 into which the frame 4 of the jack 2 is inserted and a protrusion 31 which is inserted into the mounting hole of the mounting portion 4a of the jack 2. It is formed.

In FIG. 4, a is a top view of the front plate 22, and b is a sectional view of the hole 32 into which the sleeve 3 of the jack 2 is inserted.
The hole 32 is tapered to facilitate insertion of the sleeve 3. In Figures 3 and 4, 10 holes 30 and 32 are provided so that 10 jacks can be attached.
This shows the case where 3 holes are formed, but even more holes 3 are formed.
Of course, it is also possible to increase the number of jacks to be attached by forming the number 0,32.

FIG. 5 is an explanatory diagram of the socket 24, in which c is a bottom view, a partial sectional view taken along line A-A' is a, and b is a partial sectional view taken along line B-B'. This is shown below. In the figure, 41a to 41e are terminals corresponding to terminals 11a to 11e of jack 2;
42 is a contact spring into which the terminals 11a to 11e of the jack 2 are inserted and brought into contact; 43 is a groove around the socket 24; The socket 24 is fixed by fitting the fixing metal fitting 25 into this groove 43.

FIG. 6 is a top view of the hole 30 of the mounting board 21 and the case where the jack 2 is inserted into the hole 30. This indicates that the position is fixed.

FIG. 7 is a top view of an example of how the socket 24 is attached.
Both ends are fixed to the holding plate 23 with screws 26. Note that 28 is a side plate provided on both sides of the holding plate 23. It is possible to adopt other shapes for the fixing fitting 25, but in order to facilitate the insertion of the jack 2, it is preferable to fix it so that the socket 24 can move slightly.

Effects of the Invention As explained above, the present invention provides a mounting board 21 that has a plurality of holes 30 into which the jack 2 is inserted, and a projection 31 that fits into the hole of the mounting portion of the jack, and a terminal of the jack 2. 11a to 11e, a holding plate 23 which surrounds the jack 2 with the socket 24 attached thereto, and a plurality of holes 32 into which the sleeve 3 of the jack 2 inserted into the socket 24 is inserted. and a front plate 22 which is fixed to the front surface of the mounting board 21 so as to sandwich the mounting part of the jack 2. If the jack 2 has poor contact, etc., it is easy to remove the front plate 22. jack 2 can be replaced. Further, the jack 2 can be inserted into the socket 24 and its position can be fixed by fitting the protrusion 31 into the hole of the mounting portion 4a of the jack 2, and the front plate 22 can prevent the jack 2 from slipping out. Since the jacks 2 can be easily replaced from the front in this way, there is an advantage that handling of a jack board to which a large number of jacks are attached becomes easier. Further, since the jack 2 inserted into the socket 24 is surrounded by the holding plate 23 and the like, it is possible to prevent dust from adhering to the socket 24 from the outside, and there is also the advantage that reliability can be improved.

It should be noted that the present invention is not limited to the above-mentioned embodiments, but can be modified in various ways. For example, the jack 2 may have other configurations.
