Description

[Detailed explanation of the invention] (a) Industrial application field This invention is applicable to video tape recorders (VTR),
This article relates to the mounting structure of audio jacks and video jacks for audio equipment, etc.

(b) Prior Art Figure 4 shows an example of a mounting structure for a small jack such as a microphone jack or a headphone jack. One example of this is designed such that a plug (not shown) is inserted perpendicularly to the board 24. In FIG. 4, 10 is a bracket. Bracket 10 is a plastic molding. 1
2, 12, 12 are positioning bosses, and 14 is a mounting hook. Reference numeral 16 denotes a through hole, into which the connecting portion 22 of the jack 20 is inserted.
Bracket 10 serves to house and attach jack 20 to substrate 24. 26,2
6, 26, 26 are holes into which the bosses 12, 12, 12 are inserted, and 28, 28 are holes into which the hook portion 14 is inserted. Numerals 30, 30, and 30 are holes into which electrical connection legs (not shown) of the jack 20 are inserted.

(c) Problems to be solved by the invention When a plug or the like is actually inserted into the jack 20, it is likely to receive force in directions A and B shown in FIG. A problem in which the wiring pattern (not shown) of the substrate 24 is likely to peel off due to the force in this direction is likely to occur. still,
This problem can be solved by firmly fixing the bracket 10.

However, this method increases the size of the bracket 10. Furthermore, in the mounting method shown in Utility Model Application Publication No. 56-110692 (H05K7/14), the jack becomes larger and a dedicated jack must be specially ordered. Also, the jack cannot be mounted perpendicularly to the main board.

(d) Means for solving the problems The present invention provides the hook portion 34 that engages with the board 50;
34 and housing the jack 64; an auxiliary board 60 connected to the legs 66 of the jack 64 and electrically connected to the board 50; and an engagement member that engages the storage bracket 32. It is characterized by comprising a lid 40 having a hole 42 and a through hole 44 through which a connecting portion 68 of a jack 64 passes.

(E) Effect Since the present invention has the above structure, the jack 6
4 is attached to the substrate 50 by a lid 40 and a storage bracket 32. Further, electrical connection between the jack 64 and the board 50 is made via the auxiliary board 60.

(F) Embodiment An embodiment of the present invention will be described with reference to FIGS. 1 to 3. FIG. 1 is a side view. FIG. 2 shows the lid 40 and the housing bracket 32. FIG. 3a is a plan view before attaching the lid 40;
FIG. 3b is a sectional view taken along the line CC' of a, and FIGS. 3c and 3b are side views, respectively.

In FIG. 2, 32 is a storage bracket made of plastic. This bracket 32
is U-shaped, and one of the side walls 32a, 32b, and 32c is widened. This bracket 32 is
In this embodiment, two jacks are stored. 34 is a hook portion. 36, 36 are notches for increasing the elasticity of the hook portion 34. 38 is a projection for fixing the lid 40. This protrusion 3
8 are provided on the side walls 32a, 32b, and 32c, respectively.

40 is a lid made of a steel plate material and provided with elasticity.
42 is an engagement hole into which the protrusion 38 is fitted. By fitting the protrusion 38 into the engagement hole 42, the lid 4
0 is attached to bracket 32. 44 is a through hole through which the connection portion 68 of the jack is passed.
46 is a guide bend, and this guide bend is provided to smoothly insert the lid 40 into the bracket 32.

Note that this lid 40 is expanded in the same direction as the bracket 32. Moreover, the bottom part 32d of the bracket 32
A positioning boss 37 is provided as shown in FIG. 3b. Further, the substrate 50 is provided with a positioning hole 52 into which the boss 37 is inserted.

In FIG. 3a, 50 is a substrate and 60 is an auxiliary substrate. 64 is a jack. 66 is a leg protruding from the side of the jack;
is electrically connected to the connection portion 68 of the jack 64 as usual. The legs 66 are electrically connected to the wiring pattern of the auxiliary board 60 by soldering or the like.

A connector 70 electrically connects the wiring pattern of the auxiliary board 60 and the wiring pattern of the board 50. This connector 70 can be divided into a board-side connector 70a and an auxiliary board-side connector 70b.

In the above-mentioned jack mounting structure, first, the legs 66 of the jack 64 are attached to the auxiliary board 60 by soldering, and electrical connections are made. Further, the auxiliary board side connector 70b is attached to this auxiliary board 60 by soldering.

On the other hand, regarding the board 50, a bracket 32 is attached to the board 50. At this time, as shown in FIG. 3b, the boss 37 is inserted into the positioning hole 52, and the hook portion 34 is engaged with the hole 54. Further, the board side connector 70a is also attached to the board 50.

Next, the jacks 64, 64 are placed within the attached bracket 32. At this time, the board side connector 70a and the auxiliary board side connector 70b are connected at the same time.
Connect. By connecting this connector 70, the jacks 64, 64 are temporarily held within the bracket 32. Then, as shown in FIGS. 3c and 3d, the lid 40 is inserted from the direction D, the protrusion 38 is fitted into the engagement hole 42, and the lid 40 is fixed to the bracket 32.
At this time, the through holes 44, 44 of the lid 40 are inserted into the jack 6.
Connecting portions 68, 68 of No. 4, 64 penetrate therethrough. By fixing the lid 40, the jacks 64, 64 are mounted within the bracket 32.

After this, a cabinet outer frame (not shown) having holes through which the connecting parts 68, 68 are exposed to the outside is attached to the board 5.
Just set it to 0. In this embodiment, the jacks 64, 64 are attached to an auxiliary board 60, and the auxiliary board 60 is attached to the board 50 with a separable connector 70. Therefore,
If the jacks 64, 64 are damaged, they can be easily repaired by removing the jacks 64, 64 and the auxiliary board 60.

Furthermore, the legs 66 of the extremely thin jacks 64, 64 protrude from the sides as in this embodiment for reasons such as installation safety. It can be attached to.

Further, in this embodiment, two jacks 64, 64 are arranged inside the bracket 32, but any number of jacks 64, 64 may be provided. Further, in order to securely hold the plurality of jacks 64, jacks 64 are provided on the inner wall of the bracket 32.
4.Protrusions for positioning or the like may be provided to hold individual jacks.

(g) Effects of the invention As described above, according to the invention, the jack 64 can be stably attached to the substrate 50 without requiring much space.
