The plug of the utility model is advantageous in structural simplicity, convenience, durability, and excellent insulation performance; and the plug is provided with the protection device, so the plug is further advantageous in high safety performance.

Description

A kind of plug

Technical field

The utility model relates to appliance field, refers to a kind of plug especially.

Background technology

At present, socket is requisite electrical equipment in production and family life, and supply socket is the electric equipment that power interface is provided for household electrical appliance, also is to use more electric accessories in the residential electricity design, and it and people's life have ten close relationships.Socket mainly is divided into portable supply socket, embedded wall power sockets, rack supply socket, desktop supply socket, intelligent power socket, functional electric supply socket, commercial power supply socket, power pack supply socket etc. according to structure and purposes different.Traditional socket comprises socket box, and socket box has plug surface, and plug is in plug surface inserts socket box.The pin of plug is sandwiched in the jack of socket, thereby plug is remained on the socket, guarantees to conduct.Yet, influenced by external factors, plug gets loose or drops from socket easily, and influence is normally used.Present countermeasure is to dwindle the jack of socket, tightens up the metal clips in the jack, the dynamics of clamping pin with increase.Yet the inconvenience of this method and pulling the plug out of the socket, and use the elastic force of metal clips in a period of time to weaken gradually can't prevent that the most at last plug from deviating from from socket.More existing electric outlet structure complexity, degree of safety is not high, the defective that the socket mouth is few, inconvenience when producing installation, when in use, because of some security incidents that in contact, give off sparks and cause.

The utility model content

At the deficiency that prior art exists, it is a kind of simple in structure that the purpose of this utility model is to provide, and uses simple, safety durable, double plug design and be suitable for industrial plug.

The technical solution of the utility model is achieved in that a kind of plug comprises socket head, interface and plug base; Described plug base passes interface by power line and socket head is connected; Described socket head is provided with first inserted sheet, second inserted sheet and grounding insert-pin; Described socket head is provided with protective device.

Further, described plug base one end is provided with insulating joint, be provided with in the described plug base for the hollow channel that is communicated with power line.

Further, described plug comprises first power line, second source line and the 3rd power line; Described first inserted sheet, second inserted sheet and grounding insert-pin are connected with first power line, second source line and the 3rd power line respectively.

Further: described protective device comprises the first protection convex body and the second protection convex body; The described first protection convex body is arranged on the upper end of socket head, and the second protection convex body is arranged on the lower end of socket head.

Further, described interface comprises first buckle and second buckle; Described interface is respectively arranged with first buckle and second buckle in two ends up and down.

A kind of plug construction of the present utility model is simple, and is convenient durable, good insulation preformance and be provided with protective device security performance height.
