Description
Technical field
The present invention relates to socket protective door, more particularly, to a kind of five spring hole scoket protection doors preventing the insertion of probe dystopy.
Background technology
Protection door in socket is also safety door, and the socket with protection door is usually said safety socket.Safety socket
Sleeve above be provided with insulator, need during use plug could be inserted with larger power, plug extract after in back-moving spring
In the presence of insulator automatically reset to gear above sleeve so that object can not be strayed into sleeve, thus play to prevent from touching
The effect of electricity.The safety socket meeting national requirements all has anti-one pole insertions function, i.e. either double-pole socket（It is provided only with
L pole sleeve and the socket of N pole sleeve）Or three pole sockets（It is provided with L pole sleeve, N pole sleeve and E pole sleeve（Insert also known as earth polar
Set）Socket）, when object only inserts from one of both jacks of the jack of corresponding L pole sleeve and corresponding N pole sleeve,
Safety door can not be unlocked.
Five spring hole scokets（Also known as Universal Socket, that is, there is inserting of three pole sockets and a double-pole socket and double-pole socket
The socket of the earth polar jack both sides in three pole sockets for the pore size distribution）.The protection door being arranged in five spring hole scokets referred to as five spring hole scokets are protected
Shield door.
China Patent No. be 2011203606585, authorized announcement date be on May 30th, 2012, a kind of entitled " five holes
Disclose in the patent documentation of the protection door of socket " a kind of five spring hole scokets protection doors, the protection door in this patent document include every
Piece, panel and the double-pole socket being located between partition and panel protect door, three pole sockets protection doors and back-moving spring, reset
Spring is connected to the middle part of two protection doors.This five hole protection door has double-pole socket protection door and three pole sockets protection door can
The independent advantage opened, but have the following disadvantages：Probe can penetrate into from the jack of the L pole sleeve of corresponding two pole sleeves
The N penetrating in three pole sleeves in L pole sleeve in three pole sleeves, from the jack of the N pole sleeve of corresponding two pole sleeves is extremely slotting
The L pole sleeve neutralization penetrating in set, from the jack of the L pole sleeve of corresponding three pole sleeves in two pole sleeves is extremely slotting from corresponding three
In the L pole sleeve penetrating in two pole sleeves in the jack of L pole sleeve of set, namely it is hidden to there is the safety that anti-probe is inserted into
Suffer from（Hereinafter referred to as probe dystopy insertion defect）.
It is that 2010201880896, authorized announcement date is on December 15th, 2010, entitled " a kind of uses in China Patent No.
Another kind of five spring hole scoket protection doors, five spring hole scokets in this patent are disclosed in the patent documentation of the protection door in five spring hole scokets "
Protection door includes base, partition, protection door, back-moving spring and cover, and one end of back-moving spring abuts cover, the other end abuts
Live protection door, a protection door keeps off the sleeve in the sleeve in the double-pole socket in five spring hole scokets and three pole sockets simultaneously（I.e.
Five sleeves）On.Although five spring hole scoket protection doors in this patent overcome probe dystopy insertion defect, there is following lacking
Fall into：When one of two sockets are opened, another also can open simultaneously, namely there is the safety that two sockets are opened simultaneously
Hidden danger（Hereinafter referred to as open defect simultaneously）.
Content of the invention
The invention provides a kind of do not have the prevented probe dystopy opening defect and probe dystopy insertion defect simultaneously
Five spring hole scoket protection doors of insertion, solve existing five spring hole scoket protection doors and can not eliminate unlatching defect and probe simultaneously simultaneously
Dystopy inserts the problem of defect.
