Description
Technical field
The present invention relates to connector art fields, and in particular to a kind of safe power supply identification device for for electrical connector
And method.
Background technique
Power connector is using extremely wide, and almost each electric appliance can all be used, and power connector generally comprises plug
And socket.But all there is certain risk for used power connector at present.When socket is vacant, in socket aperture still
So electrification easily causes electric shock or short circuit accident to occur if being mistakenly inserted conductive body.National regulation is in power outlet at present
Protection against electric shock door must be installed on jack, avoid the generation of some accidents, but bring other disadvantages again, such as plug plug
Arduously, it is easily damaged, and if protection against electric shock door still can be opened, and cause short when being inserted into simultaneously with conductive body by two holes
Road or electric shock accidents.Furthermore protection against electric shock door is simultaneously non-moistureproof, still it is easy that short circuit accident occurs because making moist, soaking, furthermore in plug
When plugging and unplugging half, finger touches plug pin accidentally and causes electric shock accidents.So the method for installation protection against electric shock door is not yet
It is a kind of good method.
For these problems, also produce the patent of some safety plug-in parts in recent years, such as application No. is
It is disclosed in 201210148779.2 with a kind of leakproof method for electrically and leakproof arrangements of electric connection, which includes to even
Two connection units connect, connection unit includes conductor and insulating unit, and on-off unit is equipped at least one of connection unit,
The insulating unit of two connection units contacts, and forms external conductive medium and is isolated with internal conductor, on-off unit and osculating element
Closed insulating space.For another example application No. is 201620764069.6 to disclose a kind of arrangements of electric connection with sealing mechanism, packet
The attachment base of electrification connecting hole is included, is equipped with conductor portion in attachment base, being electrically connected in hole makes conductor and attachment base equipped with sealing mechanism
Outside isolation；Sealing mechanism can be pushed to open connecting hole with the matched connection conductor of attachment base, make to connect conductor and conductor portion
Electrical contact.Above-mentioned two pieces patent is all, to prevent water from entering in attachment base, to guarantee that attachment base uses by the way that sealing mechanism is arranged
Safety, have stronger waterproof, the characteristic of anticreep, anti-short circuit；But above-mentioned patent is disadvantageous in that: if using
Similar to the rigid conductive body insertion electrical connection hole of connection conductor, it will be made to open and electric shock accidents occurs；And having
In the environment of water, which is also difficult to reject external water completely without leaking electricity completely, especially using certain
After time, due to the abrasion of sealing material, aging, deformation etc., it is easier to the danger of touching, electric leakage occur.
For another example application number 201620763779.7 discloses a kind of socket of tape relay, including shell, is equipped in shell
Contact portion, conductor portion, relay and trigger unit, conductor portion are isolated with hull outside；Relay respectively with contact portion and conductor portion
Connect and control whether contact portion is electrically connected with conductor portion, trigger unit be electrically connected contact relay control terminal and control relay switch
Movement.The patent is closed power transmission by a boot portion starting relay, and in no triggering boot portion, relay is in normally opened shape
State and will not be conductive in jack.But the patent is disadvantageous in that: when being not inserted into plug, once it is inserted in socket aperture
The other conductive bodies for entering a non-plug, restart boot portion, and electric shock or short circuit accident will occur.
