Description

Adapter {Adapter}

The present invention relates to an adapter, and more particularly to an adapter that can minimize the thickness.

In general, an adapter refers to a relay device that interconnects two or more electronic devices, or a power supply device that converts and supplies alternating current into direct current.

The adapter for a computer is one of a power supply device, and a circuit board on which a power conversion element such as a transformer is mounted is disposed in a case. In addition, one side of the case is formed with a connector, for example, a cable connection (ie, inlet) for electrically connecting with an external cable.

However, such a conventional adapter has a problem that its volume is large and inconvenient to use or carry. Therefore, modifications have been made in various forms to reduce the volume of the adapter.

However, since the conventional adapter includes an inlet to which the cable is connected, it is disadvantageous in that the volume cannot be reduced below the size (ie, thickness) of the inlet. In addition, since the inlet manufactured separately from the case is standardized, it is difficult to arbitrarily change the shape and size of the inlet. Therefore, the size of this inlet is a barrier to slipping the adapter.

Prior art document 1 is difficult to form the thickness of the adapter anymore because the inlet is manufactured separately from the case and coupled to the case.

1 to 6, the adapter 100 according to the present embodiment may be a power supply device used in a notebook computer or the like, and may include a case 10 and a circuit board 1.

The circuit board 1 may be installed in the internal space of the case 10. The circuit board 1 may perform a function of rectifying and outputting an AC voltage applied through the power pins 34 of the cable connection unit 30, which will be described later, to a DC voltage having a desired level.

To this end, a number of electronic components such as transformers (not shown) may be mounted on the circuit board 1. In addition, the circuit board 1 according to the present embodiment may be electrically connected to the power pins 34.

The case 10 may be formed of an insulating resin material, and protects the components accommodated therein from the outside. The case 10 according to the present exemplary embodiment may include a lower case 21 and an upper case 11.

The lower case 21 may have a circuit board 1 seated therein and fixed thereto. To this end, the lower case 21 may be formed in a box shape in which one surface (for example, the upper surface) is open. In addition, although not shown, at least one protrusion or groove may be formed therein so that the circuit board 1 may be easily coupled.

The combination of the lower case 21 and the circuit board 1 may be made by various methods. For example, a separate fixing member such as a screw or a fixing pin may be used, and the circuit board 1 may be interposed between the lower case 21 and the circuit board 1 by an adhesive member such as an adhesive or an adhesive tape. It is also possible to join to (21).

In addition, the lower case 21 according to the present exemplary embodiment may have a cable connection part 30 (eg, an inlet) formed on a side surface thereof. The cable connection part 30 according to the present embodiment is manufactured separately from the case 10 as in the related art, and is not coupled to the case 10, and is integrally formed with the lower case 21. That is, the cable connection part 30 may be manufactured as part of the lower case 21 in the lower case 21 manufacturing process.

Accordingly, the lower case 21 according to the present embodiment may be formed by first placing the power pin 34 in a mold (not shown) in the manufacturing process and then injecting resin into the mold.

The cable connection part 30 formed integrally with the lower case 21 partially forms the side surface of the lower case 21.

The cable connection part, that is, the inlet manufactured separately from the case 10 as in the related art, includes a cable insertion groove forming a '∞' shape and a flange extending from an inlet of the cable insertion groove and exposed to the outside. This conventional inlet has the disadvantage that the overall appearance of the inlet is greatly increased by the flange.

However, in the adapter 100 according to the present embodiment, since the cable connection part 30 is integrally formed with the lower case 21, the space occupied by the conventional flange may be reduced. That is, the peripheral space of the cable insertion groove 32 can be minimized arbitrarily as needed. Accordingly, the thickness of the case 10 may be formed to be close to the size (ie, height) of the cable insertion groove 32.

In addition, the cable insertion groove 32 of the cable connection portion 30 according to the present embodiment may be formed in a form in which the upper portion is partially open. That is, the cable connection part 30 may not be formed in a perfect shape but may be formed in a form in which a part is omitted.

And the omitted portion may be closed by the upper case 11 to be described later. That is, the cable connection part 30, in particular, the cable insertion groove 32, according to the present embodiment forms a complete shape as the lower case 21 and the upper case 11 are coupled to each other.

As such, when the cable insertion groove 32 is configured to be completed by using the upper case 11, the thickness of the cable connection part 30 may be minimized to form the cable insertion groove 32. Therefore, the adapter 100 can be formed thinner.

The upper case 11 covers the lower case 21 and forms an inner space. To this end, the upper case 11 may be formed to have an appearance similar to that of the lower case 21. That is, the upper case 11 according to the present embodiment may be formed in a box shape in which one surface (for example, the lower surface) is open.

At least one cable groove 13 may be formed at a side of the upper case 11. The cable groove 13 may be used as a hole into which a cable for electrically connecting the adapter 100 to an external electronic device such as a computer is inserted. Accordingly, the adapter 100 according to the present embodiment may also include a connection cable (not shown) for electrically connecting the circuit board 1 and an external electronic device. However, the present invention is not limited thereto, and various applications are possible such that the connection cable is detachable from the adapter 100.

Meanwhile, in the present embodiment, the case in which the cable groove 13 is formed in the upper case 11 is taken as an example, but the present invention is not limited thereto. That is, the cable groove 13 is formed on the side of the lower case 21, or the cable groove 13 is formed on both the upper case 11 and the lower case 21, and various applications are possible as necessary.

In addition, the upper case 11 according to the present embodiment may be formed with an inlet groove 14 on the side. The inlet groove 14 is a place where the cable connection portion 30 of the lower case 21 described above is inserted. As the cable connection portion 30 is inserted into the inlet groove 14 and coupled, the cable of the cable connection portion 30 is connected. The insertion groove 32 has a completed shape. Thus, the inlet groove 14 may be formed corresponding to the size of the cable connection portion 30.

In addition, at least one inlet protrusion 16 may be formed in the inlet groove 14 to complete the cable connection part 30. Inlet protrusion 16 is provided to complete the shape of the cable insertion groove 32 is formed in the '∞' shape as shown in the figure.

Therefore, the inlet protrusion 16 is formed to protrude on the inner surface of the upper case 11, and may be formed at a position corresponding to the inlet protrusion 16 formed on the cable connection portion 30 of the lower case 21. have. Also, the inlet protrusion 16 may protrude long to a length corresponding to the depth of the inlet groove 14.

The lower case 21 and the upper case 11 configured as described above may be combined by various methods. For example, a separate fixing member such as a screw or a fixing pin may be used, and the circuit board 1 may be interposed between the lower case 21 and the circuit board 1 by an adhesive member such as an adhesive or an adhesive tape. It is also possible to join to (21). In addition, it may be configured to be fitted without an adhesive member or a fixing member using a hook-type locking projection.

In the adapter 100 according to the present embodiment configured as described above, the cable connection part 30 is manufactured integrally with the case 10. Therefore, the cost of manufacturing the cable connection unit 30 separately, and the process and manufacturing time required to assemble it can be reduced.

In addition, the adapter 100 according to the present embodiment may be easily set in size or position because the cable connection part 30 is manufactured separately and is not coupled to the case 10, but is integrally manufactured with the case 10. have. Therefore, since the thickness of the cable connection portion 30 can be minimized, the thickness of the adapter can be minimized accordingly.
