And Figure 4 (a) and (b) is a view showing a plug separation process of the safety outlet according to an embodiment of the present invention.

The safety outlet according to an embodiment of the present invention is electrically connected to an indoor wiring to supply power by connecting with a plug pin, so that the power supply terminal through which electricity flows is not exposed to the outside to prevent an electric shock accident and at the same time, a power supply terminal It is characterized in that the inflow of water to the power supply terminal is blocked to prevent an electric leakage accident caused by water by blocking the inflow of water into the furnace.

To this end, the safety outlet according to the present embodiment includes a main body portion 10 having a receiving groove 11 , a connection unit 20 having a power contact terminal 21 , and a power supply having a power supply terminal 31 . Including the supply unit 30, the gender unit 40 inserted and accommodated in the receiving groove 11 in a state coupled with the plug, and a spacer unit 50 for spacing the connection unit 20 and the power supply unit 30 from each other. can be configured.

Referring to FIG. 1 in more detail, the main body 10 of the safety outlet according to the present embodiment has a receiving groove 11 . The connection unit 20 and the power supply unit 30 are disposed in the receiving groove 11 , and a plug combined with the gender unit 40 may be inserted and accommodated. The connection unit 20 is disposed in the receiving groove 11 to form a waterproof space (s) inside the receiving groove (11), and the power supply unit 30 is disposed in the waterproof space (s). That is, in the power supply unit 30 according to the present embodiment, exposure to the outside may be blocked by the connection unit 20 and the inflow of water from the outside may be blocked.

The power supply unit 30 is connected to the plug pin (pi) and provided with a power supply terminal 31 for supplying power to apply power. As such, the safety outlet according to this embodiment is a power supply terminal for supplying power. 31 is disposed in the waterproof space (s) formed by the connection unit 20, so that exposure to the outside is blocked and the inflow of water from the outside is blocked, so that a child is curiously connected to the power supply terminal 31 with a conductive object It is possible to prevent electric shock accidents such as those caused by connecting the

On the other hand, the gender part 40 is formed to be coupled to the plug pl, and may be inserted and received in the receiving groove 11 together with the plug pl in a coupled state. The gender part 40 may include a pin contact terminal 41 to which the plug pin pi is press-fitted. The connection unit 20 is provided with a power contact terminal 21 in which electricity flows in contact with the power supply terminal 31 , and the pin contact terminal 41 has a gender part 40 in the receiving groove 11 . In the inserted and accommodated state, it may be in a state in which electricity flows by contacting the power contact terminal 21 . That is, the plug pin pi is connected to the pin contact terminal 41, the pin contact terminal 41 is connected to the power contact terminal 21, and the power contact terminal 21 is connected to the power supply terminal 31, Finally, a connection between the plug pin pi and the power supply terminal 31 may be made.

However, in the safety outlet according to this embodiment, as shown in FIG. 2 , the power supply terminal 31 is not exposed to the outside, but instead comes in contact with the power supply terminal 31 to allow electricity to flow. Since the power contact terminal 21 is exposed to the outside, an electric shock accident or an electric leakage accident may occur due to the power contact terminal 21 through which electricity flows. In order to prevent an electric shock or electric leakage accident caused by the power contact terminal 21, the safety outlet according to this embodiment is an initial stage in which the plug pl combined with the gender part 40 is not inserted and accommodated in the receiving groove 11. In the state, electricity does not flow to the power contact terminal 21, and in the state in which the plug pl combined with the gender part 40 is inserted and accommodated in the receiving groove 11, the power contact terminal so that power is applied to the plug pin pi (21) can be made to flow.

To this end, as shown in FIG. 1 , in the initial state in which the gender part 40 is not inserted and accommodated in the receiving groove 11, the power contact terminal 21 and the power supply terminal 31 do not contact each other so that the connection unit ( 20) and the power supply unit 30 are spaced apart from each other, and in a state in which the gender unit 40 is inserted and accommodated in the receiving groove 11 (that is, the plug is coupled to the outlet), the power contact terminal 21 and power supply The connection unit 20 and the power supply unit 30 may be arranged in close contact with each other so that the terminals 31 are in contact with each other.

Referring to FIGS. 3 (a) and (b), in the initial state, the separation unit 50 separates the connection unit 20 and the power supply unit 30 from each other. An elastic spring interposed between the 20 and the power supply unit 30 may be applied. The power supply unit 30 includes a first magnetic body 32 , the gender unit 40 includes a second magnetic body 42 , and the power supply unit 30 is formed to be movable in the direction of distance with the connection unit 20 . can be The power supply unit 30, which is formed to be movable in the near-near direction of the connection unit 20, is disposed to be spaced apart from the connection unit by the elastic restoring force of the elastic spring in the initial state. At this time, as shown in (a) of FIG. 3, when the gender part 40 approaches the connection unit 20 within a predetermined distance, an attractive force is generated between the first magnetic body 32 and the second magnetic body 42, This attractive force moves the power supply unit 30 in the direction of the connection unit 20 as shown in (b) of FIG. 3 , so that the power supply terminal 31 and the power contact terminal 21 are connected to each other. . Therefore, when the gender part 40 is inserted into the receiving groove 11 and the pin contact terminal 41 and the power contact terminal 21 are connected to each other, the power supply terminal 31 is also the power contact terminal 21 and Since it is in a connected state, the plug pin pi coupled to the pin contact terminal 41 and the power supply terminal 31 are connected to each other, and the plug pin pi can receive power from the power supply terminal 31 . do.

Conversely, as shown in (a) of FIG. 4 , when the gender part 40 together with the plug pl is separated from the receiving groove 11, the attractive force between the first magnetic body 32 and the second magnetic body 42 is weak. As shown in (b) of FIG. 4 (b), the power supply unit 30 moves as far as possible from the connection unit 20 by the elastic restoring force of the elastic spring, and the power supply terminal 31 and the power contact terminal 21 It is possible to return to the initial state in which the connection between the two is disconnected.

For this reason, in the safety outlet according to the present embodiment, electricity does not flow to the power contact terminal 21 exposed to the outside in a state in which the plug pl is removed, and accordingly, an electric shock accident and an electric leakage accident through the power contact terminal 21 . It can also be prevented.

Preferably, the safety outlet according to this embodiment has a first magnetic body 32 and a second magnetic body 32 so that the power supply unit 30 moves toward the connection unit 20 in a state in which the gender unit 40 is in contact with the connection unit 20 . The attractive force between the magnetic bodies 42 is configured to act stronger than the elastic restoring force of the spacing unit 50, and when the user pulls the plug pl inserted and accommodated in the receiving groove 11, the gender part 40 together with the plug pl. The force-fitting force between the plug pl and the gender part 40 so as to be removed from the receiving groove 11 as well is the first magnetic body 32 and the second magnetic body 32 in the state where the gender part 40 and the connection unit 20 are in contact. It may be configured to act stronger than the attraction between the magnetic bodies 42 .

In particular, the attractive force between the first magnetic body 32 and the second magnetic body 42 has a relatively relaxed binding force compared to a typical binding force between a plug and an outlet. Therefore, when a passer-by is caught on the power line of the plug pl, the plug pl and the gender part 40 can be relatively easily separated from the receiving groove 11, so that the safety outlet according to the present embodiment is a power line It can prevent a person caught in the trap from falling or damaging electrical appliances.

Preferably, the main body 10 guides the insertion of the receiving groove 11 of the plug pl combined with the gender part 40 by chamfering the inlet periphery of the receiving groove 11 or combined with the gender part 40. The plug pl may be more easily detachable from the receiving groove 11 .

Figure 5 is a view showing one side of the power supply according to an embodiment of the present invention, Figures 6 (a) and (b) are the gender part rotation guide when the plug is connected to the safety outlet according to an embodiment of the present invention. It is a drawing showing the process.

In the safety outlet according to the present embodiment, the plug can receive power from the power supply terminal 31 only when the pin contact terminal 41 of the gender part and the power contact terminal 21 of the connection unit contact each other. Therefore, when the gender part 40 is inserted into the receiving groove 11, the circumferential arrangement of the gender part 40 must be adjusted in the forward direction so that the pin contact terminal 41 and the power contact terminal 21 can come into contact with each other, The safety outlet according to this embodiment can be naturally adjusted in the forward direction without the user particularly concerned about the circumferential arrangement of the gender part 40 when the receiving groove 11 of the gender part 40 is inserted.

To this end, in the safety outlet according to the present embodiment, when the gender part 40 is inserted into the receiving groove 11 , the pin contact terminal 41 is connected to the power contact terminal 21 in the circumferential direction of the gender part 40 . It may be provided with a guide unit 60 to guide the.

Specifically, the guide unit 60 may include a third magnetic body 61 for guiding the circumferential arrangement of the gender part 40 by pushing the second magnetic body 42 through a magnetic force. The third magnetic body 61 may be disposed in the main body 10 or the connection unit 20 or the power supply unit 30 to push the second magnetic body 42 when the circumferential arrangement of the gender part 40 is incorrect. have. That is, the third magnetic body 61 is arranged to form a magnetic force that pushes the second magnetic body 42, unlike the first magnetic body 32, and when the receiving groove 11 of the gender part 40 is inserted, the insertion angle is wrong and the pin contact When the terminal 41 and the power contact terminal 21 are not in contact with each other, by pushing the second magnetic body 42 , the gender part 40 rotates a predetermined angle and can be guided to be inserted at the correct angle.

Preferably, in order to prevent the third magnetic body 61 from affecting the first magnetic body 32 to prevent the power supply unit 30 from rotating or moving, the third magnetic body 61 is first The magnetic body 32 may be disposed on the power supply unit 30 , and the third magnetic body 61 may be disposed to be spaced apart from the first magnetic body 32 by a predetermined distance from the power supply unit 30 . If two or more first magnetic bodies 32 are disposed as shown in FIG. 5 , the third magnetic bodies 61 may be alternately disposed with the first magnetic body 32 in the circumferential direction.

The third magnetic body 61 has a groove 11 for receiving the gender part 40 at an incorrect angle that the pin contact terminal 41 does not contact the power contact terminal 21 as shown in FIG. 6 (a). When inserted into the, the second magnetic body 42 and close to generate a repulsive force by the magnetic force. And the repulsive force generated between the second magnetic body 42 and the third magnetic body 61 is a gender part so that the distance between the second magnetic body 42 and the third magnetic body 61 is as far as possible as shown in FIG. 40 is rotated by a predetermined angle, and the gender part 40 rotated by a predetermined angle is disposed at a positive angle at which the pin contact terminal 41 can contact the power contact terminal 21 . When the gender part 40 is disposed at a forward angle in this way, the second magnetic body 42 and the first magnetic body 32 are disposed closest to each other, so that between the first magnetic body 32 and the second magnetic body 42 . It can be the angle at which the force of attraction can act at its maximum.

As described above, the safety outlet according to this embodiment is by rotating the circumferential arrangement of the plug so that the pin contact terminal 41 is connected with the power contact terminal 21 of the connection unit naturally without the user's awareness when connecting the plug to the outlet. , it can make it easy to connect the plug to the outlet.
