The opening and closing disc 156 of the insertion hole 151 'having the return torsion spring 155, which is relied on by 154, is inserted into the slot 157 to open and close the insertion hole 151' by the knob 158.

The connection accommodating part 16 may include a frame including a connection inserting agent 273 and an insertion holder 163 of the remote extension outlet 200 in the body 109 and the hook extension part 164 in the holder 163. The connection terminal 161 of 101 is configured, and the ground spring terminal 162 extending the frame 102 and configured the locking bent portion 164 is configured.

The continuous extension outlet 200 comprises a plug connection portion 25 and a connection receiving portion 26 to the connection receiving portion body 209, the plug connection portion 25 'and the connection insertion portion 27 to the connection insertion portion body 209 ', the two bodies 205, 209' are connected by a remote conductor means 12 'such as a sheathed wire, and a double power frame 201, 201' and a ground frame 202, 202 'are connected to each other. Built into the two bodies (209, 209 ') and connected to the power and ground wires to the remote conductor means (212).

The plug connection portion 25 is inserted between the insertion hole 251 'for inserting the expansion plug 17 and the terminal 171 into the body 209, 209' and the double power frame 201, 201 '. It is composed of a spring crepe 251 for elastically holding the terminal 171 in an arc and a contact bullet piece 252 projected to the ground frame 202, 202 'to elastically contact the ground terminal 172. , The opening and closing disc 256 of the insertion hole 251 ', which is supported by the support shaft 254 of the bodies 209 and 209' and has the return torsion spring 255, is inserted into the slot 257 to the knob 258. The insertion hole 251 'was opened and closed.

The connection accommodating part 26 may include a power supply frame including a connection inserting agent 273 and an insertion holder 263 of the remote extension outlet 200 on the body 209 and a hook extension 264 in the holder 263. The connecting terminals 261 and 262 of 201 were formed, and the frame 202 was extended to constitute a ground spring terminal 262 having a locking bent portion 264 '.

The connection inserting portion 27 extends the body 209 'to form a connection insert 273 fitted to the connection receiving portion 16 or 26, and the connection inserting portion 275 and the engaging portion in the insert 273. The spring creeps 271 and 272 having the bent portion 274 were formed, and the frame 202 was extended to constitute the ground spring terminal 262 having the latched bent portion 264 '.

The terminal cover 300 constitutes a connection insert 363 fitted to the holder 163 or 263 of the connection receiving portion 16 or 26 and covers the connection terminal 161 or 261 on the connection insert 363. The receiving hole 361 and the spring terminal 262 was configured to accommodate the receiving groove 362.

The use of this design configured as described above is used to extend the extension outlet 100 by plugging it into a wall outlet, by inserting the insertion portion 27 of the remote extension outlet 200 into the connection receiving portion 16 of the extension outlet 100. Connect the outlet, and if necessary, connect the outlet 27 of the secondary remote extension outlet 200 to the connection receiving portion 26 of the primary remote extension outlet 200 to connect the outlet as necessary. In this case, the outlet should be connected within the range not to overload the power consumption. When the outlet is connected to the required number, the terminal cover 300 is used to close the opening of the last connection receiving portion 16 or 26 and plug the plug 17 into the plug connection portion 15 or 25.

In the plug connection portion 15 or 25, the opening and closing disc 256 blocks the insertion holes 251 ′ and 252 ′ before use. In this state, the power is concealed to prevent a short circuit or an electric shock by the insert.

To insert the plug 17, force the knob 158 or 258 to rotate the opening and closing disc 156 or 256 to open the insertion hole 151 'or 251' and insert the terminal 171 of the plug 17 into the insertion hole. (151 'or 251'). When the plug 17 is pulled out, the opening and closing disc 256 is closed as before use by the force of the torsion spring 255 to prevent the occurrence of danger.

In the state where the outlet is extended, the current passes through the plug 11, the conductor means 12 and the overcurrent protection device 13, and opens and closes the power supply state of the extension outlet according to the state of the lamp built-in switch 14, In accordance with the lamp to turn on or turn on to indicate the power supply state of the extension outlet, when the overcurrent is applied to protect the electrical appliance by blocking the current in the overcurrent protection device (13). The power frame 101 connected to the switch 14 of the extension outlet 100 is connected to the power frame 201 'of the remote extension outlet 200 to supply current to the remote conductor means 12' and the power frame 201. In addition, the power frame of the primary continuous expansion outlet 200 is connected to the secondary remote extension outlet 200 to achieve a continuous power supply.

On the other hand, when the ground terminal 112 is connected, the ground terminal 112 is connected to the ground frame 102 of the extension outlet 100 through the conductor means 12 and again the ground frame of the primary remote extension outlet 200. 202, the conductor means 12 'and the ground frame 202 is connected continuously.

In the connection state of the connection receiving portion 16 or 26 and the connection inserting portion 27, the connection insert 273 is inserted into the insertion holder 163 or 263 to make mechanical connection between extension outlets, and the connection terminal ( 161 or 261 is inserted into the spring creep 271 through the connection inserting portion 275 and is connected smoothly, the ground spring terminal 162 or 261 is to overlap the ground spring terminal 272 with an elastic pressure, In the connected state, the hook extension part 164 or 264 is coupled to the hooked bending part 164 'or 264' to the hooked bending part 274 or 274 ', respectively, so that both the power frame and the ground frame form a stable connection state.

When the extension plug 17 is plugged into the plug connector 15, the power supply terminal 171 penetrates the insertion hole 151 'or 251' and is in contact with the arc spring creep 151 or 251 to be connected to the power source. The terminal 172 is also elastically in contact with the contact ball piece 252 to achieve a stable electrical connection state.

The terminal cover 300 has a connection insert 363 fitted to the insertion holder 163 or 263 of the connection receiving portion 16 or 26 of the final extension outlet 100 or 200 and the terminals 161, 162 or 261, 262. ) Is accommodated in the accommodating hole (361) and the accommodating groove (362) to prevent external contact to prevent an electric shock accident.

For example, the extension outlet may be configured to directly protrude the power terminal and the ground terminal to the electrical insulation body 109 to omit the plug 11 and the conductor means 12, and overcurrent protection device and Inclusion of the lamp built-in open / close switch 14 can be selected commercially according to the state of the product.

As described above, this design can extend the number of outlets to the same number or more as necessary, and it is possible to ground the electrical appliances by including the grounding terminal in the extension outlet. It is possible to exclude the failure, and the connection part of the insulator is composed of the connection insertion part and the power receiving part, so that the mechanical connection state is stabilized, and the connection part is formed in the sprinkled form by constructing the power frame or the ground frame in two layers. The insertion or detachment operation of the connected terminal is flexible and the connection part maintains the elasticity of the spring, so that the electrical connection state of the connection part is good. The extension plug into the extension outlet When you turn on the terminal insertion holes it remains closed because it is possible to prevent a short circuit or electric shock.
