Receptacle and Plug Structure {RECEPTACLES AND PLUG STRUCTURE}

The present invention relates to an outlet and a plug structure, and more particularly, a power outlet inside the outlet is covered with a separate insulator, which blocks the inflow of foreign substances and simultaneously restricts physical access of the back of the hand, and overcomes the physical access limitation of the outlet. It relates to an outlet and a plug structure consisting of a plug.

Plugs and outlets are used to power home appliances and appliances. The physical form of the outlet and the plug structure is a buried type electrically connected to an indoor wiring embedded in a wall, and an exposed type connected to an embedded type outlet by extending a plurality of power terminals. It is largely divided into (露 出 形).

Of these, the outlet forming the terminal of the power source is physically open to the outside in any form, and the safety of the outlet is determined by the opening width thereof.

That is, although the inlet of the outlet into which the plug is inserted may be formed in various ways according to the voltage and the shape of the terminal, the structure in which the plug is inserted into the inlet of the outlet is almost the same.

The outlet uses a 110V or 220V power source, and if there is a foreign substance inflow, there is a risk of electric shock if a fire or a short circuit occurs due to discharge or short-circuit, or if a child enters the hand with a curiosity of immature infants or inserts a metallic material. .

Conventionally, as a shielding structure for preventing the inflow of foreign substances and electric shock, a technique for forming a separate shield on the outside of the outlet has been proposed, but when the external force is applied to a predetermined time or more, it is mostly opened.

For example, even if the outlet's power terminal is visually shielded, the plug's inlet must be opened to connect the plug, and the physical access is not completely restricted.

Therefore, if a physical structure restricting the inflow of foreign matters and the body's access to the outside and providing an outlet and a plug structure to which the power is easily connected, both conditions such as safety and ease of connection may be accommodated.

The present invention has been made in view of the above problems, an object of the present invention is to wrap the power terminal inside the outlet with a separate insulator to block the inflow of foreign substances and restrict the body access of the back of the hand, and physical access restriction of the outlet It is to provide a plug that overcomes.

Another feature of the present invention is that the safety door that can be opened and closed by a hinge on the inlet of the outer case.

Another feature of the present invention is that inclined surfaces are formed on both front sides of the insulator so that a pair of plug power terminals are separated from each other upon insertion.

When described in detail with reference to the accompanying drawings an embodiment of the present invention that can realize the above objects and features in the most preferred form.

1 is a perspective view showing the overall configuration of the present invention in an intuitive manner, and simultaneously shows an outlet and a plug structure, which are main components of the present invention.

As shown in the figure, the present invention consists of an outlet 100 forming a terminal of a power connection device and a plug 200 coupled thereto.

Among them, first, the outlet 100 will be described.

Although the shape of the outlet case 110 is illustrated as a recess in the drawing, as an embodiment of the structural modification, the outlet case 110 may be formed of a structure forming the external shape of the power strip.

The insulator 140 is positioned and fixed to the housing 120 formed at the rear of the outlet case 110. The insulator 140 has a box-shaped structure that spatially partitions the inside and the outside.

Inside the insulator 140, an outlet terminal 141 is provided as in FIG. 2, and the outlet terminal 141 is electrically connected to the indoor wiring 143 again.

On both sides of the insulator 140, a locking groove 142 for restricting opening of the inside and the outside of the insulator 140 is formed. The locking groove 142 has a slot shape having a predetermined width and height.

Meanwhile, an inlet 111 for inleting the plug 200 is formed in front of the outlet case 110 described above. The inlet 111 is formed in a size and shape into which the plug 200 can be inserted, and a safety door 130 rotatably supported at an inlet thereof is formed.

The support structure of the safety door 130 is elastically rotatably supported by the hinge both the upper end of the safety door 130 and the inlet 111 and the elastic means is a general torsion spring or can be given elasticity Other elastic members (not shown) are provided between them.

On the other hand, the plug 200 according to the present invention is introduced into the outlet 100 to make an electrical connection as follows.

The external shape of the plug case 210 of the present invention is formed within a range not leaving the shape of a rectangular parallelepiped or a rectangular parallelepiped as shown in FIG. 3, and the locking jaw 200a and the non-slip groove 200b are external to the plug case 210. It is formed in.

The plug terminal 230 (see FIG. 1) is fixed inside the plug case 210. The plug terminal 230 is fixed to a fixture 220 structurally integrated with the plug case 210, and the fixture 220 fixes both sides between the lower portions of the pair of plug terminals 230, and maintains them at a predetermined interval. It also has the function to

Thus, the shape of the plug terminal 230 fixed to the fixture 220 is made of a conductive metal having a predetermined width or diameter, and has a structure in which a bent portion 231 having a predetermined inclination angle is formed at one side in a longitudinal direction thereof. The upper portions of the pair of plug terminals 230 are not fixed to the structure, thereby enabling elastic bending.

Meanwhile, a tension pad 240 that moves in a straight line with respect to the longitudinal direction of the plug terminal 230 is provided between the plug terminals 230.

The tension pad 240 moving in a straight line is elastically connected to the fixture 220 by the spring 250 and has a function of providing a restoring force and tension by elasticity according to the position of the tension pad 240.

4 and 5 show the electrical and physical connection of the outlet and the plug structure of the present invention configured as described above, as shown in Figure 4 plug 200 located outside the outlet 100 to the outlet 100 When pushed in, the plug case 210 enters the inlet 111 of the outlet case 110 first.

As such, when the plug case 210 is pulled in and reaches a certain position, the tension pad 240 therein comes into contact with the front surface of the insulator 140 inside the outlet 100, thereby further restricting further progress.

When the plug 200 is continuously pushed in the state in which the progression of the tension pad 240 is limited as described above, the upper end of the plug terminal 230 elastically supported on both sides thereof is released, so that both ends of the insulator 140 of the outlet 100 are released. The inclined surface 144 is formed on both sides.

The unplugged plug terminal 230 slides on both sides of the insulator 140 while maintaining elasticity as the plug 200 progresses to reach the locking grooves 142 of both sides, and reach the locking grooves 142. The elasticity of the instantaneous plug terminal 230 is released and the end thereof enters into the locking groove 142 to make an electrical connection with the outlet terminal 141.

Such a state provides a battery connection and at the same time provides a very stable locking structure, and the holding force of the locking is determined by the elastic force according to the opening degree of the plug terminal 230.

Here, the outlet terminal 141 wrapped into the insulator 140 is shielded against the outside but is partially opened by the locking groove 142, thereby restricting the inflow of foreign substances and access of the body. The electrical connection provides a structure that can be performed.

On the other hand, the safety door 130 is rotatably supported at the inlet 111 of the outlet 100 is to open the inlet elastically at the first entry of the plug 200, the end is located on the plug case 210 upper surface do.

At this time, the safety door 130 is always generated by the spring connected to both ends to generate a restoring force to be directed downward and when the user removes the plug 200 from the outlet 100 to the original position by the restoring force again By returning, the inlet 111 is blocked from the outside.

Of course, the user can open the safety door 130 directly, not the opening and closing by the plug 200, but the blocking state of the outlet inlet 111 is maintained unless it is opened with any intention.

The inflow of foreign matter through the outlet inlet 111 is primarily blocked by the safety door 130 as described above, and the foreign matter once introduced into the outlet terminal 141 is secondarily blocked by the insulator 140. to be.

In addition, when a curious infant inserts a conductive metal material such as chopsticks or the like into his or her hand around the outlet 100 around the outlet 100, the outlet terminal 141 inside the outlet 100 is exposed to the outside. An insulating insulation structure can provide a secure power supply terminal that restricts access to the body.

As described above, the present invention wraps the terminals inside the outlet with a separate insulator, and provides an outlet that blocks the entry of foreign substances and restricts the body access of the back of the hand, and provides a plug that overcomes the physical access limitation of the outlet. It can prevent electric shock or short circuit caused by the inflow of foreign substances.

In other words, the outlet terminal is mostly wrapped around the outside by an insulator formed inside the outlet, thereby restricting the access of the body such as the back of the hand and inflow of foreign substances, which is the main cause of the short circuit, is primarily in the insulator in the safety door. It is effective to provide a double blocking film by blocking by.
