Technical Field

The present invention relates to an electrical plug, and more particularly, to an electrical plug that can be applied to various types of sockets.

Background

Generally, an electric device or an electric product is provided with a plug at an end of a power supply to be inserted into a power outlet for supplying the power.

The plug is formed to be used at 110V or 220V according to the corresponding difference of the power supply used in the common household. Generally 110V power supplies have access means in-line and 220V power supplies have access means in circular form.

Therefore, in order to use electric devices or electric products that are standardized for distribution from a household power supply of 110V or 220V as described above at these two voltages, an adapter is attached to one power supply plug so as to be used as a different power supply.

Fig. 1 shows an example of this.

Fig. 1 is a perspective view showing the configuration of an existing 110/220V-compatible separation type plug.

As the number of households using 220V increases, the conventional plug is used at 110V by attaching a 110V adapter (20) to a 220V plug (10) connected to a cord. Specifically, a 220V plug (10) having a circular insertion member (12) is directly inserted into a 220V receptacle (not shown) and used, while a 110V receptacle is used by attaching a 110V adapter (20) to the front of the plug (10) and inserting a straight insertion member (22) provided in the adapter (20) into the receptacle.

The circular insertion member (12) of the plug (10) is inserted into an insertion hole (24) formed in the rear surface of the adapter (20), whereby the circular insertion member (12) and the linear insertion member (22) of the adapter (20) are electrically connected.

Generally, the 220V access member is formed in a cylindrical shape, and the 110V access member is formed of a straight plate member.

Of course, there is a product in which a 220V adapter is mounted on a 110V plug connected to a cord.

As described above, since the conventional separable plug requires the adapter to be attached or detached when used in place of 110V or 220V, it is not only troublesome to use it, but also it is necessary to store the detached adapter, which makes it highly likely that the adapter will be lost.

In addition, the adapter is installed at the front part of the plug, so the adapter obviously protrudes from the wall surface where the power socket is located, thereby not only the plug is caught by passing people and is frequently fallen off, but also the adapter has the defect that the adapter is not easy to be accessed in a narrow gap space.

Further, since the two-piece structure is made of two parts, there is a problem that the volume is large and the manufacturing cost is increased.

And, the one-side 2-1 st pin (461a) and the one-side 2-2 nd pin (462a) protrude to the outside of the access plug main body portion (410, 420) so as to be inserted into a socket, and the other-side 2-1 st pin (461b) and the other-side 2-2 nd pin (462b) are located inside the access plug main body portion (410, 420).

The access plug main body portion (410, 420) includes: a first connection wiring (401a) connecting the other side 1 st-1 st pin (451b) and the other side 2 nd-1 st pin (461 b); and a second connection wiring (401b) connecting the other side 1-2 st pin (452b) and the other side 2-2 nd pin (462b), the other side 1-1 st pin (451b) and the other side 2-1 st pin (461b) being electrically connected through the first connection wiring (401a), and the other side 1-2 nd pin (452b) and the other side 2-2 nd pin (462b) being electrically connected through the second connection wiring (401 b).

Referring next to fig. 14-19, the access plug (400) of the present invention comprises: a first slot portion (471) located on a first side of the access plug body portion (410, 420); and a second slot portion (472) located on a second side of the access plug body portion (410, 420).

More specifically, the first groove section 771 includes: a 1-1 st slot (471a) located on a first side of the access plug body (410, 420) and disposed adjacent to the first pin portion (450); and a 1-2 slot (471b) located on a first side of the access plug body portion (410, 420) and disposed adjacent to the second pin portion (460), and the second slot portion (772) includes: a 2-1 slot (472a) located on a second side of the access plug body portion (410, 420) and disposed adjacent to the first pin portion (450); and a 2 nd-2 nd slot (471b) located on a second side of the access plug body portion (410, 420) and disposed adjacent to the second pin portion (460).

Here, the number of slots of the first slot portion and the second slot portion is two, respectively, but in the present invention, the number of slots may be one or more, respectively, and the present invention does not limit the number of slots.

However, when the access plug is coupled to one side of the body plug portion (200, 300), the pressing portion constitutes a slot into which the slot portion must be inserted. This will be explained later.

In addition, the slot of the present invention is located on the first side surface of the access plug main body portion (410, 420) or the second side surface of the access plug main body portion (410, 420), and is continuously arranged from the access plug first main body portion (410) to the access plug second main body portion (420).

The structure of the slot portion will be described later.

Referring next to fig. 14 to 19, the access plug first body portion (410) of the present invention includes a first coupling groove (481) at a designated area of the access plug first body portion (410), and the access plug second body portion (420) of the present invention includes a second coupling groove (482) at a designated area of the access plug second body portion (420).

As shown in fig. 9 and 10, the first fitting portion (310) of the main body of the inlet plug portion includes a coupling hole (315) located in the first space (312) region of the first base plate (311) and penetrating the first base plate (311).

As described above, the electrical plug (100) of the present invention includes: a body plug portion (200, 300); and an access plug part (400) which is attached to and detached from one side of the body plug part (200, 300).

That is, since the inlet plug part (400) of the present invention is attached to and detached from one side of the main body plug part (200, 300), the inlet plug part (400) is coupled to the main body plug part (200, 300), or the inlet plug part (400) is detachable from the main body plug part (200, 300).

Here, in a state where the inlet plug part (400) is coupled to one side of the body plug part (200, 300), the coupling hole (315) and the first coupling groove (481) are coupled by a fixing mechanism, thereby preventing the inlet plug part (400) from being arbitrarily separated from one side of the body plug part (200, 300).

In contrast, in a state where the inlet plug part (400) is coupled to one side of the body plug part (200, 300), the coupling hole (315) and the second coupling groove (482) are coupled by a fixing mechanism, thereby preventing the inlet plug part (400) from being arbitrarily separated from one side of the body plug part (200, 300).

Here, the fixing means may be a well-known bolt, that is, the coupling hole (315) and the first coupling groove (481) are fixed by the bolt, or the coupling hole (315) and the second coupling groove (482) are fixed by the bolt, whereby the inserting plug part (400) can be prevented from being arbitrarily separated from one side of the body plug part (200, 300).

In addition, when the bolt penetrates the first body part 410 of the inlet plug, the bolt contacts with the inner structure of the inlet plug part 400, so that an electric shock accident occurs due to the bolt, and therefore, the bolt should not penetrate the first body part 410 of the inlet plug, and thus the first coupling groove 481 should be formed in a groove form rather than a hole form.

For the same reason, when the bolt penetrates the second body part 420 of the access plug, the bolt contacts the structure inside the access plug part 400, and an electric shock accident occurs due to the bolt, and therefore the bolt should not penetrate the second body part 420 of the access plug, and thus the second coupling groove 482 should be configured in a groove form instead of a hole form.

Referring next to fig. 14 to 19, the first coupling groove (481) includes: a 1 st-1 st coupling groove (481a) disposed adjacent to the first pin portion (450); and a 1 st-2 nd coupling groove (481b) disposed adjacent to the second pin portion (460) and spaced apart from the 1 st-1 st coupling groove (481a) by a predetermined interval.

And, the second coupling groove (482) includes: a 2-1 th coupling groove (482a) disposed adjacent to the first pin portion (450); and a 2 nd-2 nd coupling groove (482b) disposed adjacent to the second pin portion (460) and spaced apart from the 2 nd-1 th coupling groove (482a) by a predetermined interval.

Here, the drawings show that the number of the first coupling groove and the second coupling groove is two, but the number of the grooves may be one or more in the present invention, and the present invention does not limit the number of the grooves.

However, in the present invention, when the access plug is coupled to one side of the body plug part (200, 300), the coupling hole (315) and the first coupling groove should be located at a corresponding region, and the coupling hole (315) and the second coupling groove should be located at a corresponding region.

For example, in the case where the number of the first coupling groove and the second coupling groove is two as shown in the drawing, when the first pin part (450) of the inlet plug part (400) is inserted into the body plug part (200, 300), the coupling hole (315) and the 1 st-1 st coupling groove (481a) should be located in a corresponding region, or the coupling hole (315) and the 2 nd-1 st coupling groove (482a) should be located in a corresponding region.

In the case where the number of the first coupling groove and the second coupling groove is two, respectively, and the second pin portion (460) of the inlet plug portion (400) is inserted into the body plug portion (200, 300), the coupling hole (315) and the 1-2 coupling groove (481b) should be located in a corresponding region, or the coupling hole (315) and the 2-2 coupling groove (482b) should be located in a corresponding region.

More specifically, the first groove section 771 includes: a 1-1 st slot (471a) located on a first side of the access plug body (410, 420) and disposed adjacent to the first pin portion (450); and a 1-2 slot (471b) located on a first side of the access plug body portion (410, 420) and disposed adjacent to the second pin portion (460), and the second slot portion (772) includes: a 2-1 slot (472a) located on a second side of the access plug body portion (410, 420) and disposed adjacent to the first pin portion (450); and a 2 nd-2 nd slot (471b) located on a second side of the access plug body portion (410, 420) and disposed adjacent to the second pin portion (460).

Here, when the access plug is coupled to one side of the body plug part (200, 300), the pressing part constitutes a slot that must be inserted into the slot part.

More specifically, the pressing part has a partial structure in which the first catching protrusion 614 of the first pressing part 610 and the second catching protrusion 624 of the second pressing part 620 must be inserted into the groove of the groove.

For example, in the case where the first slot portion 771 includes the 1 st-1 st slot (471a) and the 1 st-2 st slot (471b) and the second slot portion (772) includes the 2 nd-1 st slot (472a) and the 2 nd-2 nd slot (471b) as shown in fig. 14 to 16, in the case where the first pin portion (450) of the access plug portion (400) is inserted into the body plug portion (200, 300), it is necessary that the first catching protrusion (614) of the first pressing portion (610) is inserted into the 1 st-1 st slot (471a), the second catching protrusion (624) of the second pressing portion (620) is inserted into the 2 nd-1 st slot (472a), or the first catching protrusion (614) of the first pressing portion (610) is inserted into the 2 nd-1 st slot (472a), and the second protrusion (620) of the second pressing portion is inserted into the 1 st-1 st slot (472a), (471b), (772) is inserted into the 1 st-1 st slot (471b) 471a) In that respect

And, in contrast, in the case where the first slot portion 771 includes the 1 st-1 st slot (471a) and the 1 st-2 st slot (471b) and the second slot portion (772) includes the 2 nd-1 st slot (472a) and the 2 nd-2 nd slot (471b) as shown in fig. 14 to 16, in the case where the second pin portion (460) of the inlet plug portion (400) is inserted into the body plug portion (200, 300), the first catching protrusion (614) of the first pressing portion (610) should be inserted into the 1 st-2 th slot (471b), the second catching protrusion (624) of the second pressing portion (620) should be inserted into the 2 nd-2 th slot (472b), or the first catching protrusion (614) of the first pressing portion (610) should be inserted into the 2 nd-2 nd slot (472b), the second catching protrusion (624) of the second pressing part (620) is inserted into the 1 st-2 nd groove gap (471 b).

With the above configuration, when the first pin portion (450) of the access plug portion (400) is inserted into the main body plug portion (200, 300), or when the second pin portion (460) of the access plug portion (400) is inserted into the main body plug portion (200, 300), the access plug portion (400) can be prevented from being separated from the main body plug portion (200, 300).

In order to separate the inlet plug part (400) from the body plug part (200, 300), the inlet plug part (400) may be separated from the body plug part (200, 300) by releasing a state in which the first hooking protrusion (614) of the first pressing part (610) and the second hooking protrusion (624) of the second pressing part (620) are inserted into the slot of the slot part by pressing the pressing plates, i.e., the first pressing plate (612) of the first pressing part (610) and the second pressing plate (622) of the second pressing part (620).

For example, referring to fig. 22, the first latching protrusion 614 of the first pressing portion 610 and the second latching protrusion 624 of the second pressing portion 620 are moved in a downward direction by a first pressing plate 612 of the first pressing portion 610 and a second pressing plate 622 of the second pressing portion 620 being pressed in the downward direction from an upper direction, and the first latching protrusion 614 of the first pressing portion 610 and the second latching protrusion 624 of the second pressing portion 620 are released from being inserted into the groove of the groove, and then the access plug portion 400 is separated from the body plug portion 200, 300.

Here, when the first pressing plate (612) of the first pressing portion (610) and the second pressing plate (622) of the second pressing portion (620) are pressed from the upper direction to the lower direction, the first elastic body (616) and the second elastic body (not shown) are compressed, and when the force of the first pressing plate (612) pressing the first pressing portion (610) and the second pressing plate (622) pressing the second pressing portion (620) from the upper direction to the lower direction is removed, the compressed first elastic body (616) and the compressed second elastic body (not shown) return to their original states, and the first pressing portion and the second pressing portion return to their original positions.

Here, the second coupling terminal (522) is connected to a wiring or a circuit, and power can be finally applied to a product connected to the wiring or the circuit.

The first pin portion second insertion portion (524) includes a 2-1 st plate (524a) extending from the other side surface in the longitudinal direction of the second base terminal (521) and arranged to be bent at a predetermined angle from the second base terminal (521).

And the second pin portion second insertion portion (523) includes: a 2-2 plate (523a) extending from one side surface in the width direction of the second base terminal (521) and bent at a predetermined angle from the second base terminal (521); and a 2-3 plate (523b) which is arranged to face the 2-2 plate (523a), extends from the other side surface of the second base terminal (521) in the width direction, and is bent at a predetermined angle from the second base terminal (521).

Herein, the first pin portion second insertion portion (524) includes a first pin portion second insertion space (524b) between the side surfaces of the 2-2 nd and 2-3 nd plates (523a, 523b) and the plate surface of the 2-1 st plate (524a), and the second pin portion second insertion portion (523) includes a second pin portion second insertion space (523c) between the plate surface of the 2-2 nd plate (523a) and the plate surface of the 2-3 rd plate (523 b).

In addition, the one-side 1 st-1 st pin (451a) and the one-side 1 st-2 nd pin (452a) protrude to the outside of the access plug main body portion (410, 420) so as to be inserted into a socket, and the one-side 2 nd-1 st pin (461a) and the one-side 2 nd-2 nd pin (462a) protrude to the outside of the access plug main body portion (410, 420) so as to be inserted into the socket.

Here, for example, when the one-side 1 st-1 st pin (451a) and the one-side 1 st-2 st pin (452a) are inserted into the socket, the one-side 2 st-1 st pin (461a) and the one-side 2 nd-2 nd pin (462a) are coupled to the pin connecting terminal (500), more specifically, the one-side 2 nd-1 st pin (461a) is coupled to the second pin first insertion space (513c), and the one-side 2 nd-2 nd pin (462a) is coupled to the second pin second insertion space (523 c).

For example, when the one-side 2-1 st pin (461a) and the one-side 2-2 nd pin (462a) are inserted into the socket, the one-side 1-1 st pin (451a) and the one-side 1-2 nd pin (452a) are coupled to the pin connecting terminal (500), more specifically, the one-side 1-1 st pin (451a) is coupled to the first pin first insertion space (514b), and the one-side 1-2 nd pin (452a) is coupled to the first pin second insertion space (524 b).

When the one-side 1-1 st pin (451a) and the one-side 1-2 st pin (452a) are inserted into the socket, the power transmitted to the one-side 2-1 st pin (461a) and the one-side 2-2 nd pin (462a) is transmitted to the pin connection terminal (500), and the pin connection terminal is connected to a wire or a circuit, so that the power can be finally applied to a product connected to the wire or the circuit.

On the contrary, when the one-side 2-1 st pin (461a) and the one-side 2-2 nd pin (462a) are inserted into the socket, the power transmitted to the one-side 1-1 st pin (451a) and the one-side 1-2 nd pin (452a) is transmitted to the pin access terminal (500) which is connected to a wire or a circuit and can finally apply the power to a product connected to the wire or the circuit.

As described above, the one-side 1 st-1 st pin (451a) and the one-side 1 st-2 nd pin (452a) protrude to the outside of the access plug main body portion (410, 420) so as to be inserted into the socket, and the one-side 2 nd-1 st pin (461a) and the one-side 2 nd-2 nd pin (462a) protrude to the outside of the access plug main body portion (410, 420) so as to be inserted into the socket.

For example, when the one-side 1-1 st pin (451a) and the one-side 1-2 st pin (452a) are inserted into a socket, the one-side 1-1 st pin (451a) and the one-side 1-2 st pin (452a) receive power from the socket, and power applied to the one-side 1-1 st pin (451a) and the one-side 1-2 st pin (452a) can be transmitted to the one-side 2-1 st pin (461a) and the one-side 2-2 nd pin (462 a).

The power transmitted to the one side 2-1 st pin (461a) and the one side 2-2 nd pin (462a) is transmitted to the pin connection terminal, which is connected to a wire or a circuit, and to which the power can be finally applied to a product connected to the wire or the circuit.

In contrast, for example, when the one-side 2-1 st pin (461a) and the one-side 2-2 nd pin (462a) are inserted into a socket, the one-side 2-1 st pin (461a) and the one-side 2-2 nd pin (462a) receive power from the socket, and power applied to the one-side 2-1 st pin (461a) and the one-side 2-2 nd pin (462a) can be transmitted to the one-side 1-1 st pin (451a) and the one-side 1-2 nd pin (452 a).

The power transmitted to the one side 1-1 st pin (451a) and the one side 1-2 st pin (452a) is transmitted to the pin access terminal, which is connected to a wire or a circuit, and to which the power can be finally applied to a product connected to the wire or the circuit.

Therefore, according to the present invention, whether the second pin portion is inserted into the socket or the first pin portion is inserted into the socket depends on whether the first pin portion of the access plug is inserted in the inner direction of the body plug portion or the second pin portion of the access plug is inserted in the inner direction of the body plug portion, so that it is possible to provide a compatible plug applicable to sockets of various forms.
