Description
Technical field
The present invention relates to the technical field of electrical equipment, specifically a kind of socket and plug.
Background technology
The connection of the plug and socket of prior art, generally by being arranged in pairs in the inserted sheet and socket on plug
Connection sheet grafting.I.e. the two sides of inserted sheet are close to two connection sheets, when two connection sheet deformations loosen and cause inserted sheet and two
When individual connection sheet is changed into a contact or linear contact lay, it will cause the resistance of transient state excessive and catch fire, therefore the two of prior art
Spacing between individual connection sheet is often below the thickness of inserted sheet, so as to ensure that inserted sheet with two connection sheets is always that face contacts.
But this is in the prior art, because the spacing between two connection sheets is small, therefore the dynamics needed for inserted sheet insertion
Greatly, and to its installation accuracy require high, when two between connection sheet and inserted sheet because assembly precision is poor or long-term use of
And when causing deformation, it will cause inserted sheet to misplace and can not normally insert with two connection sheets, this is also the socket of prior art
The technical problem of generally existing.
In addition, easily come off when by larger external force effect after the plug insertion socket of above-mentioned prior art, example
Such as the computer mains plug of office space, being stumbled when people's pin can then cause plug to depart from socket due to the kicking power of pin, so as to
Computer accident power-off is shut down, thus may result in the loss of computer information.In addition, electrical equipment also holds in moment accident power-off
Easily cause the damage of electrical equipment.
The content of the invention
