Specific implementation mode
As shown in the figure, specific implementation mode is as follows:
A kind of insurance triangle plug seat, including upper cover 3 and lower cover 1, upper cover 3 are bolted on lower cover 1, upper cover 3
Wiring hole 2 is offered between lower cover 1, and jack is offered in upper cover 3, contact is provided on lower cover 1, contact is matched with jack and set
It sets, and is connected with the power cord across wiring hole 2, the jack includes firewire hole 10, null line hole 11 and ground string holes 9, institute
The contact stated includes firewire contact 8, zero curve contact 13 and ground wire contact 4, and the height of the firewire contact 8 is equal to zero curve contact
13 height, the height of firewire contact 8 and the height of zero curve contact 13 are less than the height of ground wire contact 4, firewire contact 8 and zero curve
Safety device is additionally provided between contact 13, the safety device includes:Safeguard 5, safeguard guide holder 7 and resetting apparatus
6, safeguard guide holder 7 is fixed on lower cover 1, and safeguard 5 is slidably arranged on safeguard guide holder 7, and the setting of resetting apparatus 6 exists
For making safeguard 5 reset between safeguard 5 and safeguard guide holder 7.
The ground wire contact 4 is made of two symmetrically arranged contacts 12, and the bottom end of contact 12 is connect with ground wire.
The safeguard 5 includes that guide plate 501, substrate 504 and two block protection plates 503, guide plate 501 are fixed on vertically
The middle part of substrate 504, guide plate 501 and substrate 504 are in integral structure, and guide plate 501 is located at firewire contact 8 and zero curve contact 11
Between, and one end of guide plate 501 is stretched between 4 two contacts 12 of ground wire contact, two block protection plates 503 are separately positioned on guiding
The both sides of plate 501, and positioned at 11 top of firewire contact 8 and zero curve contact so that protection board 503 is in lucky energy when guard mode
Enough block firewire contact 8 and zero curve contact 11, to play a protective role, guide plate stretch into 4 two contacts 12 of ground wire contact it
Between part set there are one lead-in chamfered, lead-in chamfered can guide plug to push guide plate 501 when bearing plug active force
It is mobile so that guide plate 501 drives protection board 503 to leave guard mode, and firewire contact 8 and zero curve contact 11 can connect with plug
It touches, 503 guard mode of safeguard refers to protection board 503 when socket does not work, and protects the receptacle connector of corresponding protection board 503 not
The state being exposed, in the case where resetting apparatus 6 is in reset state, the lead-in chamfered position opposite with ground string holes 9 is higher than guarantor
The upper surface of backplate 503, the lead-in chamfered being arranged so not only can guide plug to facilitate insertion, while avoiding plug and inserting
It is fashionable to be expressed to protection board 503, to cause to use problem, offered for 6 one end of fixating repositor on guide plate 501
Reseting groove I502.
The angle of inclination of the lead-in chamfered is 30-80 °, and angle of inclination is unspecified angle between 30-80 °, and
Angle be when being 45 ° it is best, at this time plug be inserted into when it is most light, be least susceptible to problem.
The safeguard guide holder 7 includes guide pad 702 and the pedestal 701 for fixed guide block 702, pedestal 701
It is connected through a screw thread and is fixed on lower cover 1, the sliding slot 704 for guiding guide plate 501 is offered on guide pad 702 and be used for solid
Determine the reseting groove II703 of 6 other end of resetting apparatus.
The resetting apparatus 6 is spring.
The height of firewire contact 8 in the present invention is equal to the height of zero curve contact 13, and the height and zero curve of firewire contact 8 are touched
First 13 height is less than the height of ground wire contact 4, therefore is first grounded again with electric appliance during socket use, can effectively discharge
Electrostatic.
When socket does not use in the present invention, protection board 503 be located at firewire contact 8 and zero curve contact 13 just on
Side, the underface of corresponding jack, efficiently solves the problems, such as that contact is exposed, one end of guide plate 501 is in ground wire at this time in this way
Between 4 two contacts 12 of contact.
The socket use of time in the present invention, a promotion guide plate 501 of plug earthed is so that one of ground connection can
To be inserted into jack and contact release electrostatic with ground wire contact 4, while guide plate 501 drives protection board 503 to slide, and firewire touches at this time
First 8 and zero curve contact 13 it is exposed and and Plug contact, while guide plate 501 can between firewire contact 8 and zero curve contact 13
Electric spark is generated with effective barrier, when use finishes, resetting apparatus 6 pops into position guide plate 501.
