The present invention relates to a case for electronic equipment.
The present invention relates to a DIN connector mounting structure in which an IN connector is mounted using ring solder.

[0002]

2. Description of the Related Art DI mounted on a case for electronic equipment
As shown in FIG. 6, the N-connector usually has an insertion portion 43 inserted into a circular insertion through-hole 32 formed in the electronic device case 30 and an upper end of the insertion portion 43 to form the insertion portion. A circular fitting portion 42 fitted into the through hole 32,
A large-diameter portion 41 is formed at the upper end of the fitting portion 42, and the ring solder 35 attached to the fitting portion 42 is melted to be attached to the surface of the electronic device case 30. Have been.

[0003] At the lower end of the DIN connector 40,
Three terminal portions 44 are provided which are inserted into contact portions provided on a circuit board provided in the electronic device case, and two of them (for grounding) are opposed to each other. Is disposed at an intermediate position between the two terminal portions.

[0004]

In the above-described DIN connector mounting structure, when the ring solder mounted on the DIN connector is melted, the molten solder flows from the gap between the insertion through hole 32 and the fitting portion 42 to the back of the case. In some cases, the case may flow out or may not sufficiently rotate around the outer periphery of the DIN connector, which may result in poor connection between the case and the DIN connector.

In addition, since the insertion hole of the case and the fitting portion of the DIN connector are both circular, it is difficult to position the DIN connector with respect to the case in the rotational direction, and the DIN connector is difficult to rotate.
There is also a problem that the terminal cannot be inserted into the circuit board even when the IN connector is inserted.

In view of the above, the present invention can reduce the situation where the molten solder flows out to the back side of the case and does not sufficiently reach the outer periphery of the DIN connector. It is another object of the present invention to provide a DIN connector mounting structure that can easily position the DIN connector with respect to the case in the rotational direction.

[0007]

In order to achieve the above-mentioned object, a DIN connector mounting structure according to the present invention includes an insertion portion inserted into an insertion hole formed in a case for an electronic device, and the insertion portion. And a large-diameter portion formed at the upper end of the fitting portion. The ring solder attached to the fitting portion is melted. Thereby, a DIN connector adapted to be attached to the surface of the electronic device case is used, and the shape of the insertion through hole formed in the electronic device case is made oval, and at least one It is characterized in that a concave portion is formed, and the cross-sectional outer shape of the fitting portion of the DIN connector is an oval shape corresponding to the insertion through hole.

[0008]

The DIN according to the present invention having the structure described above is provided.
In the connector mounting structure, when the ring solder mounted on the DIN connector is melted, the molten solder slightly flows out to the front surface of the case, but does not flow out too much to the back surface of the case, and circulates around the outer periphery of the DIN connector. For this reason, there is no possibility that poor connection between the case and the DIN connector occurs. In addition, since the cross-sectional shape of the fitting portion of the DIN connector is an oval shape corresponding to the insertion through hole, the DIN connector can be easily positioned in the rotational direction with respect to the case. There is no problem that it cannot be inserted into the substrate.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a DIN connector, a ring solder, and a case for an electronic device used in the DIN connector mounting structure according to the present invention.

The DIN connector 20 has an insertion portion 23 inserted into an insertion hole 12 described later formed in the electronic device case 10, and is formed at an upper end of the insertion portion 23 and fitted into the insertion hole 12. The fitting portion 22 and the fitting portion 22
And a large-diameter portion 21 formed at the upper end of the case. The ring solder 35 mounted on the fitting portion 22 is melted to be attached to the surface of the electronic device case 10.

The case for an electronic device is, for example, for an RF modulator, and two cases are provided at both ends of the upper surface thereof.
The two insertion through holes 12, 12 are formed at regular intervals.

As shown in detail in FIG. 2, the shape of the insertion through-hole 12 is formed in an oval shape, and a pair of narrow sides of the oval-shaped insertion through-hole 12 are formed in a side peripheral portion having a narrower width. The concave portions 14 are formed to face each other, and the cross-sectional shape of the fitting portion of the DIN connector 20 is formed in an oval shape corresponding to the insertion through hole 12 as shown in detail in FIG.

In this embodiment, a C-shaped groove 15 is formed around each of the insertion holes 12, 12.

The DIN of this embodiment having such a configuration is
In the connector mounting structure, the insertion through hole 12 has an oval shape, a concave portion 14 is formed on the outer periphery thereof, and the cross-sectional outer shape of the fitting portion 22 of the DIN connector 20 is in the insertion through hole 12. When the ring solder 35 attached to the DIN connector 20 is melted, the molten solder H flows from the recess 14
Of the DIN connector 2
It goes around the circumference of 0 well. As a result, a proper amount of the molten solder H can be provided on the front and back surfaces of the case 10, and the DIN connector 20 can be fixed on the front and back surfaces of the case 10, so that the joint failure between the case 10 and the DIN connector 20 is reduced. it can.

Further, the fitting portion 22 of the DIN connector 20
Is formed in an oval shape corresponding to the insertion through-hole 12, the DIN connector 20 can be easily positioned relative to the case 10 in the rotational direction.
The problem that the terminal portion 24 cannot be inserted into the circuit board does not occur.

In addition, when the ring solder 35 mounted on the DIN connector 20 is melted, as shown in FIG.
In this example, the molten solder H slightly flows out of the surface of the case 10 as shown in FIG. 15 is provided, the flow destination of the molten solder H stops in the concave groove 15.

Therefore, the molten solder H is transferred between the case 10 and DI.
It is possible to avoid a situation in which the connection portion and the N connector 20 are greatly spread, and as a result, poor appearance and poor connection are reduced.

Further, since the molten solder does not flow out significantly, there is an advantage that the joining strength and the assembling strength between the case 10 and the DIN connector 20 are improved.

[0019]

As is apparent from the above description, according to the DIN connector mounting structure according to the present invention, the insertion through hole has an oval shape, a concave portion is formed on the outer periphery thereof, and the DIN connector is provided. When the ring solder attached to the DIN connector is melted, some of the molten solder flows out to the case surface because the cross-sectional shape of the fitting portion of the connector is an oval shape corresponding to the insertion through hole. It does not flow too much to the side and goes around the outer periphery of the DIN connector well, so that there is no danger of poor connection between the case and the DIN connector. In addition, since the cross-sectional shape of the fitting portion of the DIN connector is an oval shape corresponding to the insertion through hole, the DIN connector can be easily positioned in the rotational direction with respect to the case. The problem that it cannot be inserted into the substrate does not occur.
