Description

The fixing means of charger and socket and charger thereof

Technical field

The present invention relates to the fixing means and the charger thereof of a kind of charger and socket, particularly relate to and a kind ofly the charger of digital products such as mobile phone, MP3, MP4 or digital camera can be securely fixed in the charger on the socket and the fixing means and the charger thereof of socket.

Background technology

Disclose among the disclosed Chinese patent bulletin CN2403133Y on October 25th, 2000 a kind of " inserting the wall type charger for mobile phone ", mainly comprise the insertion slot that is opened in the top, and the plug of being located at a side wall surface, wherein this insertion slot is an inner concavity, inside is available puts in order to do charge or discharge for mobile phone or battery, flat the establishing of this plug protrudes from the side wall surface, and this charger body inside is provided with electronic circuit; Charger (portable round) directly is inserted in the socket on the wall and can locatees and use, exempt puzzlement and inconvenience that the known charge device need extend electric wire.The shortcoming of this charger is: charger for mobile phone is insecure with being connected of wall during use; Because mobile phone (mobile phone) is inserted in the insertion slot when using, the weight of mobile phone that has been equivalent to be inserted in charger extra duty on the wall, and charger for mobile phone is to be fixed by the friction between the jack on power pin and the wall socket, as long as it is excessive to be subjected to less external force effect or mobile phone weight, then fall down from wall easily, and the charger slot interpolation of working as on being fixed on wall is gone in the process of mobile phone, may make also that charger is stressed to be moved or fall down, so, when the slot interpolation is gone into mobile phone, must use extremely inconvenient with the hand steered firmly charger of another.

Summary of the invention

The objective of the invention is for solve exist in the existing charger be connected insecure, inconvenient problem with use with socket, and provide a kind of simple in structure, easy to use, the charger that can firmly be connected with socket and the fixing means and the charger thereof of socket.

The object of the present invention is achieved like this: the fixing means of a kind of charger and socket, wherein said socket is the Three-hole socket of band single phase poaer supply jack and ground wire jack, be fixed with the power pin that matches with described single phase poaer supply jack on the shell of described charger, it is characterized in that having on the described charger case size and screw rod external diameter quite and over against the through hole of the ground wire jack of described Three-hole socket, screw front end be provided with "T"-shaped head or

The shape head, with the "T"-shaped head on the screw rod or

The shape head stretches into described ground wire jack inward turning and turn 90 degrees, make "T"-shaped head or

The card base that the shape cephalic par crosses out is stuck in the inboard of described socket panel, the clamp nut of screwing on the end of screw rod outside described through hole stretches out charger.

Another technical scheme is: the fixing means of a kind of charger and socket, wherein said socket is the Three-hole socket of band single phase poaer supply jack and ground wire jack, be fixed with the power pin that matches with described single phase poaer supply jack on the shell of described charger, it is characterized in that having on the described charger case size and screw rod external diameter quite and over against the through hole of described ground wire jack, screw front end be provided with "T"-shaped head or

The shape head, with the "T"-shaped head on the screw rod or

The ground wire jack inward turning that the shape head stretches into socket turn 90 degrees, make "T"-shaped head or

The card base that the shape cephalic par crosses out is stuck in the inboard of described socket panel, on screw rod, screw on preposition nut then and described screw rod is fixed in the ground wire jack of described socket, again the power pin on the charger case is inserted in the described supply hub clamp nut of on the end of screw rod outside described through hole stretches out charger, screwing on.

A kind of charger, comprise electronic circuit board and shell, wherein in the electronic circuit board charging circuit is set, be fixed with two power pins that the single phase poaer supply jack with Three-hole socket matches on the described shell, two power pins are electrically connected with described charging circuit respectively, it is characterized in that having on the described shell size and screw rod quite and over against the through hole of the ground wire jack of described Three-hole socket, the "T"-shaped head of front end band or

The screw rod outer end of shape head is stretched out the shell outside through described through hole and is matched with the clamp nut screw thread, the "T"-shaped head of described screw front end or

The shape head can stretch in the ground wire jack of described socket.Socket of the present invention (Three-hole socket) is existing reference power supply socket on the market, so the manufacturer uses when of the present invention, does not need to be equipped with separately Three-hole socket, and the user can directly use the Three-hole socket in the family.

Described charger is characterized in that described screw rod front portion is furnished with preposition nut, and this nut is fixed on described screw rod in the ground wire jack of described socket.

Socket of the present invention (Three-hole socket) is existing supply socket on the market.So the manufacturer when use is of the present invention, can be unworthy of the stand-by power source socket in the charger of selling.

Owing to adopted technical solutions according to the invention, by be with "T"-shaped head or

The retention mechanism that the screw rod of shape head and clamp nut constitute, directly use the fastener hole of the ground wire jack of socket as retention mechanism, and do not need in addition on the wall or perforate promptly can be fixedly locked in socket with charger on the socket panel, have advantage simple in structure, easy to use, also can not destroy socket simultaneously.Charger can guarantee after placing several mobile phones on the charger, also can not fall, so can charge to several mobile phones simultaneously from socket.
