Abstract
A rotator provided with two or more than two self-locking devices is arranged on a power socket. The self-locking devices are simultaneously opened making use of the maximum depth of immersion when a plug is inserted. Then a certain angle is rotated by hand. An inserting sleeve fixed on the rotator in the socket contacts a spring piece connected with electricity through a contact piece exposed outside. At this point in time the inserting sleeve is provided with electricity. A locked groove is arranged on the pin of the plug. If the locked groove is rotated, the locked groove is engaged with a locked belt in the socket. The pin of the plug can not be extracted. The pin of the plug can be extracted if the pin of the plug is reset. Simultaneously the self-locking devices on the rotator are reset. When the rotator is not rotated, any conducting body inserted from an insertion opening can not contact live parts.
Description
Appliances power source safety plug socket the utility model is a kind of safety plug socket that is used for the appliances power source of electrical engineering.Be applicable to individual event two-stage, three grades of individual events, three kinds of three-phase level Four.
Known safety socket is to load onto protective device as insulation catch or slide block and so at the spigot of socket, can play the effect that prevents from directly touching charged position.French Patent (FRP) (FR2451646) is exactly the safety socket that belongs to such type.Therefore and the safety socket of energized in addition, French Patent (FRP) (FR2517891) is a kind of mechanism that has adorned 45 ° of moving rotations can be along with the insertion of plug the time on socket, and.
The shortcoming of above safety socket is, can be only inserts in it or rotating mechanism is rotated and causes the problem of electric shock with the conductor of the similar plug latch of single shape.
Task of the present utility model is to make a kind of shortcoming that does not have above safety socket fully, the appliances power source safety plug socket of safety and reliability.
Finishing of above task is by sleeve (1) being fixed on the circulator made from insulating material (4) (seeing figure one) on the socket, forms sealing with charged part in the socket.On circulator (4), be equipped with and contain plural self-locking device (2), after plug (6) inserts (seeing figure two), utilize the maximum insertion depth of plug latch (7), finish all self-locking devices (2) on the circulator (4) all opened simultaneously, then manually with plug (6) together with circulator (4), rotate to an angle, make and connect electrical spring sheet (3), energized in the socket in sleeve contact (5) contact that is embedded on the circulator (4).In addition, on plug latch (7), have locked groove (8).Opened self-locking device (2) on the circulator (4) once the anglec of rotation at plug (6), the locked groove on the plug latch (8) just with socket internal lock band (9) engagement (seeing figure three), can not extract, must can extract by resetting.Meanwhile, along with extracting of plug, the self-locking device (2) on the circulator (4) also can reset simultaneously.
This kind appliances power source safety plug socket secure coefficient is higher.Often go deep into any conductor from spigot and can not touch charged position, therefore, profile can be art up, not can because of young age children curiosity and cause the problem of electric shock.
The manufacture method of appliances power source safety plug socket is equal to the making of ordinary plug socket.
Claims (4)
1, the safety plug socket that is used for appliances power source can be made three kinds of individual event two-stage, three grades, three level Four of individual event.A circulator made from insulating material (4) is arranged on the socket, and sleeve is fixed thereon.Two (containing) above self-locking device (2) is housed on the circulator (4).Plug is opened the self-locking device on the circulator (4) after inserting.Then, logotype circulator (4) rotates to an angle together, and the sleeve contact (5) on the circulator (4) is touched, and the electrical spring sheet (3) that connects in the socket has been connected power supply.It is characterized in that, often, sleeve (1) is not charged, probe into any conductor from spigot and can not touch charged position.
2, according to the appliances power source safety plug socket of claim 1, it is characterized in that, two self-locking devices (2) more than (containing) are housed on circulator (4), and controlled by the maximum insertion depth of plug regulation.Insertion depth excessive and not enough all can cause circulator (4) not rotate, and, must open all self-locking devices (2) on the circulator (4) simultaneously, can make its rotation.
3, according to the appliances power source safety plug socket of claim 1, it is characterized in that on the plug latch, having locked groove (8), plug together with circulator (4) once rotation, the locked groove of plug latch just with socket in lock band (9) engagement, can not extract, must can extract through resetting, meanwhile, the self-locking device (2) on the circulator (4) also will reset simultaneously.
4, according to the appliances power source safety plug socket of claim 1, it is characterized in that external form can be art up.
