Abstract

The utility model relates to a power inserting apparatus, particularly an automatic pull-up power plug which can automatically separate from a socket. The utility model comprises a plug pin seat, a casing and plug pins, and is characterized in that an elastic mechanism which is composed of an electromagnet and a push rod is arranged in the casing which is positioned above the plug pin seat. When electric appliances are cut off by the remote control, direct current is input into the electromagnet in the plug to generate electromagnetic force which prompt a push rod press the plug to separate from the plug. The utility model has the advantages of simple structure, reasonable design, easy production, low cost, safety and easy use, and realizes the remote control of the power cut-off of the electric appliances with the remote control apparatus.

Description

Automatic pull-up power plug

The utility model relates to electric power connecting device, especially a kind of attaching plug that can break away from socket automatically.

At present, various types of plugs are a lot of on the market, these plugs with being used of socket in, all need remove to pull up plug with hand, just can cut off the electricity supply, it is suitable for most electrical appliances.But for the electric equipment products of the higher band remote control of automaticity, just seem not ideal enough, made things convenient for inadequately, the electric equipment products that are provided with remote control can realize the machine that opens or closes of remote control apparatus product by hand-held remote controller, and the control of other project, but can not realize attaching plug is pulled up from socket, fundamentally cut off the electricity supply.And must go plug is pulled away socket with hand.

The purpose of this utility model is the deficiency that exists at above-mentioned common pin, and what a kind of electric equipment products that are suitable for being provided with remote control were provided pulls out attaching plug automatically.

The utility model pulls out attaching plug automatically and comprises pin base, shell and pin, it is characterized in that being provided with in the shell of pin base top one by T shape movable core, the fixing ejecting mechanism that constitutes of magnetic conduction iron, electromagnet coil and push rod and return spring, two lead C, D of electromagnet coil, lead C directly is connected to pin lead A, lead D directly draw and another pin lead B between the string establish a direct current relay, push rod is located in the pin base central through hole.

The utility model pulls out attaching plug automatically when the electric equipment products that are used to remote control, as long as this plug is inserted supply socket, two pins of plug are about to power supply by lead A, B imports electric equipment products, at this moment electric equipment products can operate as normal, but in the time of need shutting down and cut off the electricity supply, as long as click the shutdown button of remote controller, the shutdown circuit of electric equipment products is started working, output dc voltage, make the direct current relay adhesive conducting that is serially connected between lead D and the B, produce electromagnetic force behind the electromagnet coil power, adhesive T shape movable core, the montant of T shape movable core pushes push rod, and the front end of push rod is withstood in the supply socket, produce reaction force and impel plug to extract, realize cutting off the electricity supply from socket.The utility model pulls out automatically that electrical prong structure is simple, reasonable in design, easy to manufacture, and cost is low, and is especially safe and reliable, easy to use, has realized the straighforward operation of band remote control electric equipment products dumps.This plug is applicable to all kinds of electric equipment products with remote control.

The concrete structure that the utility model pulls out attaching plug is automatically provided in detail by the following drawings and embodiment.

Fig. 1 is the structural representation that pulls out attaching plug automatically;

Fig. 2 pulls out attaching plug to use circuit diagram automatically.

Embodiment:

Can be clear that from Fig. 1, automatically pull out attaching plug and comprise pin base 2, shell 1, pin 3 and 4, it is characterized in that: be provided with one in the shell 1 of pin base 2 tops by T shape movable core 5, fixedly magnetic conduction iron 6, be located at the electromagnet coil 7 in the fixing magnetic conduction iron 6, and the ejecting mechanism of push rod 8 and return spring 13 formations, fixedly magnetic conduction iron 6, the center of pin base 2 all has through hole, push rod 8 is arranged in the central through hole, the upper end of push rod 8 is provided with boss, the boss upper surface contacts with the montant end face of T shape movable core 5, the boss of push rod 8 and fixedly between the central through hole of magnetic conduction iron 6 return spring 13 is set, an end of push rod 8 is exposed to pin base 2 central through holes.Two lead C, D of electromagnet coil 7, lead C directly is connected to pin 4 lead A, lead D directly draw in the plug and pin 3 lead B between string establish a direct current relay 11(and see Fig. 2), three lead A, B, D and the direct current relay 11 of being drawn by plug all insert in electric equipment products 12, and remote control receives the on/off circuit of electrical equipment.

For prevent bullet from supply socket pull out the attaching plug damage of falling automatically, drawing of plug a hook 10 is set on the lead 9.

Push rod 8 adopts insulating material to make.
