Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a power socket that is integrally equipped with, for example, an AC and a DC jack unit.

Power sockets that are integrally equipped with AC and DC jack units are widely used in various electrical products, such as tape recorders and the like. Therefore, conventional power sockets of this type do not have AC power in the socket body.
The commercial and DC jack units were integrally formed. For example, only the size of the main parts of a DC jack unit is subject to various standards, such as EIAJ.
If the standard or DIN standard differs, the mold for molding the entire socket body will be replaced with a separate mold. For this reason, there was a problem in that the manufacturing cost increased. In order to solve this problem, recently, for example, a DC jack unit formed separately based on various standards is attached to a predetermined location of a socket body that is integrally formed with a general-purpose AC jack unit. I am planning to finish it. In this case, it is sufficient to prepare molds and the like for molding the unit body of the DC jack unit based on various standards.
This makes it possible to reduce manufacturing costs. However, when manufacturing a DC jack unit, conventionally the connection pins and connection terminals are fixed at the predetermined locations by caulking the predetermined portions of the connection pins inserted into the predetermined locations of the unit body, and these are electrically connected. I had it connected to. For this reason, a process for caulking the required portions of the connection pins is required, which increases the number of man-hours required to manufacture the DC jack unit itself, resulting in a corresponding increase in manufacturing costs.

Also, in recent years, small radio-cassette players, etc., are often equipped with only a DC socket without an AC socket, but in this case, the DC socket is usually installed near the jack board that has the signal output connectors, so the above-mentioned I had the same problem.

The present invention was developed in view of the above circumstances, and an object of the present invention is to provide a power socket equipped with a DC jack unit that can reduce manufacturing man-hours and manufacturing costs.

To this end, the present invention involves inserting a separately formed DC jack unit into a predetermined location of a socket body in which an AC jack unit is integrally formed, at right angles to the longitudinal direction of a connecting pin protruding from the unit. It is characterized in that the connecting terminal attached to the DC jack unit is covered by a cover member formed at a required portion of the socket body to prevent the connecting terminal from falling off.

The switch portion 31 of the cover member 3 is configured as follows.

The switch part 31 includes a switch contact piece 314 and a rotating member 313 into which the switch contact piece 314 is press-fitted.
and a connecting wire 312 that contacts the switch contact piece 314.
a, 312b, 312c, and a frame 311 that rotatably supports a rotating member 313.

A rectangular cylindrical frame 311 is formed on the lower side of the cover member 3 with its longitudinal direction facing forward and backward. A rotary member 313 into which a switch contact piece 314 as shown in FIG. 6 is press-fitted is rotatably supported within the frame 311. As shown in FIG.

The switch contact piece 314 is made of a conductive metal plate, and has an opening 314b in the center.
A notch 314a is provided at one corner, and has a shape resembling a digital number "9" when viewed from above. Further, the switch contact piece 314 is curved with a predetermined curvature R.

The rotating member 313 is made of an insulating material such as synthetic resin, and a switch contact piece 314 is press-fitted therein. This rotating member 313 has a press-fitted portion 313a having a substantially semicylindrical shape having a predetermined curvature R.
and a protrusion 313b extending from the back surface of the press-fit portion 313a. In addition, the rotating member 313
A pair of shafts 313d protrudes from the side surfaces of. Note that 313c is a stopper that restricts the rotation of the rotating member 313.

When the switch contact piece 314 is press-fitted into the press-fit portion 313a, the portion 313m corresponding to the opening 314b is formed flush with the surface of the switch contact piece 314, and the notch 31
The portion 313n corresponding to 4a is also the switch contact piece 31.
It is formed to be flush with 4. Moreover, protrusions are formed in the circumferential direction at both ends of the portion 313m (see FIG. 6).

Next, the operation of the switch section 31 will be explained.

When the AC jack is not inserted, the connection wires 312a and 312c contact the switch contact piece 314 on the dashed line a. Connection line 31
2b is in contact with a portion 313m of the rotating member 313 exposed from the opening 314b of the switch contact piece 314 (see FIG. 5A).

When the AC plug is inserted, the protrusion 313b is pressed at the bottom of the AC plug, and the rotating member 313 rotates about the shaft 313d. Then, the connection line 31
2a, 312b, 312c are switch contacts 314
Alternatively, the contact point with the switch contact piece 314 is moved while sliding on the surface of the rotating member 313. In other words,
The connection line 312b contacts the switch contact piece 314 on the dashed line b, and the connection line 312c contacts the rotating member 313. However, the connection line 312
a is always in contact with the switch contact piece 314 (see FIG. 5B).

That is, when the AC plug is inserted, the connecting wire 312a and the connecting wire 312b are connected via the switch contact piece 314, and when the AC plug is not inserted, the connecting wire 312a and the connecting wire 312b are connected via the switch contact piece 314.
12c is connected via a switch contact piece 314.

When the AC plug is inserted, the connection wire 312a
Since the cassette tape recorder is connected to the connection line 132b, the cassette tape recorder is driven by AC power. If the AC plug is not inserted, the connecting wires 312a and 312c are connected, and the cassette tape recorder is driven by DC power. In other words, the switch section 31 has a switch function for switching between AC power source and DC power source.

As is clear from the above description of an embodiment of the present product, according to the present invention, a DC jack unit formed separately based on various standards is installed at a predetermined location of the socket body equipped with the first jack unit. Since the unit is installed and finished, molds and the like for molding the unit body of the DC jack unit need only be prepared based on various standards, thereby reducing manufacturing costs. Furthermore, since a DC jack unit in which the connecting pin and the connecting terminal are integrally formed is attached, the manufacturing process can be reduced. Furthermore, if the size of the main parts of the DC jack unit differs based on various standards,
By making the color of the unit body different depending on the standard, the present invention has excellent effects, such as preventing confusion of products during manufacturing.

In addition, as an example of this product, we have described an example of a power socket that is integrally equipped with an AC jack unit and a DC jack unit, but it is also possible to attach a DC jack unit to a jack board that has signal input/output connectors attached. A similar effect can be obtained when they are attached integrally.
