This manuscript concerns safety outlets.

Conventional outlets always have a current that flows even when the plug is not plugged in. As a means of preventing electric shocks caused by children inserting chopsticks or nails into the plug insertion holes, a separate cover is plugged when the outlet is not used. Preventing such electric shock by inserting into the insertion port is the applicant's utility model registration application No. 91-1540 "outlet safety cover" devised by the applicant, but it is inconvenient to have the safety cover separately and it is not lost or inadvertently inserted. In order to solve such problems, there is a shortcoming that is not sufficient as a means of preventing electric shock accidents of children because it is inadequate in case of the case. In Utility Model Registration Application No. 193-14058 "Safety Outlet" designed by the applicant, To prevent current from flowing It was designed to prevent electric shock even when a child inserts chopsticks or nails by inserting the plug into the outlet and at the same time, but in this case, the connecting plate connecting the two separate terminals is connected to the top connection of the terminal by the seesaw method. Since the tip and the interruption of the plate did not come into contact with the top connection of both terminals at the same time, the defect that could not be correctly connected was overcome.

The present invention is invented to correct such a problem and described in detail by the accompanying drawings as follows.

This manuscript divides the upper surface of the rectangular outlet board 1 into partitions 1 '(1 ") (1'") (1 ""). The storage compartment 4 and the plug compression plate storage chamber 5 are arranged symmetrically with each other, so that the box upper terminal 6 with the inner wall opened and the connection part 6 'formed on the bottom of the terminal storage chamber 4 is screwed. (7) and the plug inserting portion (10, 10 ') is staked in the box upper terminal (9) in which the inner wall is opened and the connecting portion (9') is formed at the bottom of the compression plate storage chamber (5). The plug compression plate 8 is accommodated, and the connection plate storage chamber 3 has a round bar 14 having a flange 15 at the upper end and an connecting plate fixing body 16 which is an insulator at the lower end thereof on the support 11. On both sides of the connecting plate fixture (16). The connecting plate support 13 on which the conductor connecting plates 17 and 18 formed with the "shaped vanes 17 ', 17, 18' and 18" is formed at the distal end thereof is provided. The lower end of the round bar (14) is attached to the support portion (11) on the bottom of the coil spring (22) and tangled over the outlet top (2) to cover the top of the yellow bar (14) out of the perforation (19), the action of the spring in normal When the terminal is disconnected and the plug is plugged in, the bottom of the plug pushes down the round bar so that the blades are energized to the bottom connection.

The effect of this manuscript is explained as follows.

The outlet in this manuscript is normally plugged by using the box upper terminal 6 and the box upper terminal 9 connected to the wiring by the partition wall 1 'in a state where electricity does not flow. Is inserted into the plug insertion hole (21) (21 ') installed in the upper outlet plate (2), while the plug bottom surface (20) is maintained by the flange (15) while maintaining the proper position of the upper outlet plate (2) As the connecting plate support 13 descends by pressing down the upper end of the round bar 14 protruding outward, the blades 17 ', 17 ", 18' (18 ') ( 18 ") abuts on the bottom connecting portion of the terminals 6 and 9 to connect both terminals to allow electricity to flow therethrough.

That is, the plug bottom surface 20 'presses down the upper end of the round bar 14, and the connecting plate support 13 coupled to the lower end of the round bar 14 and supported by the coil spring 22 is pushed down accordingly to the connecting plate support 13. The staked conductor connecting plates 17 and 18 are also lowered, while the blades 17 ', 17 ", 18' and 18" of the conductor connecting plates 17 and 18 are connected to the terminal 6 as well. The contact portion 6 'and the contact portion 9' of the terminal 9 are brought into contact with each other so that current flows to enable operation of the plug. On the other hand, when the plug is discontinued and the plug is removed, the blades 17 ', 17 ", 18", 18 "and 18" of the conductor connecting plates 17 and 18 are connected to the terminals 6 due to the elasticity of the coil spring 22. (9) It is released from the connection part 6 'and 9' of the bottom surface and is restored to its original position, so that the electric current is cut off, and even if a child inserts chopsticks or nails into the plug insertion hole 21, 21 ', the electric shock may be caused. There is no safety. On the other hand, the connecting portion of the terminal should be leaned slightly higher so that the wings of the conductor connecting plates 17 and 18 touch when the connecting plate support 13 descends.

As such, the present invention is a very useful design that can prevent an unexpected electric shock of a child by using a normal plug by making a slight change in the electrical outlet.

Claims (1)

The rectangular outlet board 1 is divided into partitions 1 ', 1 ", 1'", and 1 "" by the top surface of the rectangular outlet board 1, and the terminal storage chamber 3 and the terminal storage chamber on both sides in the longitudinal direction. 4) and the plug compression plate storage chamber 5 are arranged symmetrically with each other, and the terminal housing chamber 4 has a box upper terminal 6 having an inner wall open and a connection part 6 'formed at the bottom thereof, and having a screw 7 And the plug compression plate 8 having the plug inserting portion 10, 10 ′ staked in the box upper terminal 9 formed on the bottom of the compression plate storage chamber 5. In the connecting plate storage chamber 3, a round bar 14 having a flange 15 at the upper end and an connecting plate fixing body 16 which is an insulator at the lower end is mounted on the supporting parts 11 and 11 '. 16) on both sides " A connecting plate support 13 on which conductor connecting plates 17 and 18 formed with "shaped wings 17 ', 17", 18' and 18 "is formed at the distal end thereof is provided. Reattach the lower end of the round bar (14) to the support section (11) and squeeze it with the coil spring (22) and cover the outlet top plate (2) so that the top of the round bar (14) comes out of the hole (19). When the connection of the terminal is cut off by the action of the plug, the bottom of the plug pushes the round bar so that the blades of the connecting plate are connected to each of the connecting parts so that they are energized.
