Abstract

The utility model relates to a safety connector for a power source, which is divided into a socket part and a connector pin part. The root part of a metal plug on the connector pin is wrapped with one layer of insulation film, and the head of the metal plug is bare. The depth of a hole on an upper panel of the socket which is matched with the connector pin is greater than the length of the bare part of the metal plug of the connector pin, and the upper panel is provided with the hole. The utility model has the advantage of safe and reliable operation.

Description

A kind of mains connection safe in utilization

The utility model relates to a kind of mains connection safe in utilization, particularly a kind ofly mates the connector that connects with socket, plug mode safe in utilization.

At present, in the mains connection that uses, with socket, connect in the majority and various in style that the pin mode connects, the specification pattern differs, but total connected mode all is in the conducting metal reed in the conducting metal plug insertion socket on the latch, so that circuit is coupled together.The shortcoming of this connected mode is that the latch metallic plug is all exposed on its total length, if careless in the use, during conducting metal reed in metallic plug has contacted socket, the root of its metallic plug does not insert in the socket as yet fully, at this moment hand or other conducting objects promptly have Danger Electric shock risk as running into, even if in use, latch is inserted socket to have suffered, as be not seated, still have outside one section conductive metal contact is exposed to, if any conducting objects, run into as iron wire etc., still have to make people's Danger Electric shock risk.

The purpose of this utility model is to improve the shortcoming of prior art and a kind of mains connection safe in utilization is provided, and that is to say provides a kind of socket safe in utilization, latch connector of mating.

The purpose of this utility model is to realize like this, mains connection is designed to socket, latch two parts, metallic plug radicle branch on its latch is surrounded by one deck dielectric film, its head is exposed, with the degree of depth in the hole of the top panel with holes of the socket of the latch coupling exposed part length greater than the latch metallic plug.Be preferably greater than 2 millimeters-6 millimeters.Like this, when latch is installed on socket, no matter how careless the user is, even finger contacts the exposed part of the metallic plug of latch, can not get an electric shock, because this moment, metallic plug failed to be inserted in the live metal reed in the socket, if the interior live metal reed of the metallic plug of latch and socket has contacted yet, that part that is exposed at the outer metallic plug of socket then is to have had the part of dielectric film, and people or other conducting objects are run into also and can not got an electric shock.

The utility model can be designed to the socket and plug of the one-tenth coupling use of different specification size.But specification whatsoever, the exposed length part of metallic plug that all should guarantee latch is less than the hole depth of socket top panel with holes, and such mains connection production is simple, safe in utilization.

Quote embodiment below, details are as follows in conjunction with the accompanying drawings.

Embodiment 1

The utility model is designed to socket 1 and latch 2 two parts, the radicle branch of the metallic plug 3 on its latch is surrounded by one deck dielectric film 4, its head is exposed, with the degree of depth in hole 6 on the top panel with holes 5 of the socket of the latch coupling exposed part 3-14 millimeter greater than the latch metallic plug.Like this, when having only exposed part when metallic plug all to insert in the hole of socket, metallic plug just can snap in the conducting metal reed 7 of socket.

Claims

1, a kind of mains connection safe in utilization, be divided into socket, latch two parts, metallic plug radicle branch on the latch is surrounded by one deck dielectric film, it is characterized in that and the degree of depth in the hole of the top panel with holes of the socket of the latch coupling exposed part length greater than the latch metallic plug.

2, a kind of mains connection safe in utilization as claimed in claim 1, it is characterized in that with the degree of depth in the hole of the top panel with holes of the socket of latch coupling greater than 2 millimeters-6 millimeters of the exposed part length of latch metallic plug.
