Abstract

The utility model relates to a single-phase power source plug which comprises pins, inserted handles, inserted handle covers and springs. The utility model is characterized in that the plug is divided into a left part and a right part, namely, a left inserted handle and a right inserted handle. The front ends of the two inserted handles are connected through a thin wall structure, the two pins are arranged at the front ends of the left inserted handle and the right inserted handle, spring seats are arranged at the inner sides of the middle part and the back part of the left inserted handle and the right inserted handle of the plug correspondingly, and the springs are arranged on the spring seats. The inner sides of the left inserted handle and the right inserted handle are also provided with column bodies.

Description

The single phase poaer supply plug

The utility model relates to the appliance switch technical field, particularly a kind of single phase poaer supply plug.

In the daily life, the employed one-time formed different detachable plugs that together bring with the power line of purchasing power line or electrical equipment are because one-time formed production, two pins are fixing dead, and the pin tension will be loose excessively but used of a specified duration, no matter be pine or tension, they all have a lot of drawbacks.If pin is loose excessively, can make that to insert the back insecure, thereby with the sheet metal loose contact of socket, easily produce sparking, or virtual connection is touched and is formed excessive resistance; Time has been grown the coupled lead of pin is fractureed in addition, thereby produces short circuit or sparking.If pin tension, loosening with the pin that can make of a specified duration, in addition when the shared socket of several plugs, when some plugs insert or extract, other plug generation temporarily or is fully opened circuit, be usually said " scintillation " phenomenon, " scintillation " this phenomenon harm is very big, and especially the picture tube harm to television set is bigger.For fear of the loosening drawback of being brought of pin, metal contact in a lot of sockets on the market, design very tightly, especially a kind of socket of " travelling contact type " that cries is tighter, though this has overcome the loosening drawback of pin to a certain extent, but it is because too tight, it all is very hard making when inserting and pulling up, have in addition can not insert fully, this has brought difficulty and dangerous to use, especially use and electrical equipment breaks down suddenly when needing emergency power off as child, more dangerous and inconvenient.In addition, because tension, the easier plug that makes damages, thereby produces series of malpractice.

The purpose of this utility model provides a kind of socket of different spacing jack that is applicable to and uses and contact single phase poaer supply plug closely.

The utility model is achieved in that it comprises pin, discloses handle, spring, it is characterized in that inserting handle branch left and right sides two parts, and pin is embedded in the inserting handle, connects together by the thin-wall construction that is provided with between two inserting handles.Be provided with spring between two inserting handles, inserting handle can drive pin by cooperatively interacting of thin-wall construction and spring, and front and back are movable together, change the width between two pins, also are provided with to be used to limit the movable within the specific limits cylinder of pin between two inserting handles.

The utility model has the advantages that: the pin width-adjustable, and when plug pine, it is tight to insert the back, thereby tight with the binding of socket, safe and reliable, is difficult for sparking and short circuit take place, alternative existing attaching plug also has characteristics simple in structure, easy to use.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is the structural representation of single phase poaer supply plug.

As shown in Figure 1, this unidirectional attaching plug comprises pin 1, inserting handle 2, spring 3, it is characterized in that 2 fens left and right sides two parts of inserting handle, and pin 1 is embedded in to be disclosed in the handle 2, links together by the thin-wall construction 4 that is provided with between two inserting handles 2.Be provided with spring 3 inserting handles 22 of two inserting handles and can drive pin 1 front and back activity together by cooperatively interacting of thin-wall construction 4 and spring 3, change the width between two pins 1, disclose also to be provided with between the handle 2 at two and be used to limit the movable within the specific limits cylinder 5 of pin 1.

Claims

A kind of single phase poaer supply plug is characterized in that: plug is divided into left and right two parts, two inserting handles promptly, the front end of two inserting handles is connected by thin-wall construction, two pins are contained on the inserting handle, in the left and right handle of plug, the posterior medial correspondence establishes spring base, shock mount on the spring base, about the inboard of two inserting handles, also be provided with the movable within the specific limits cylinder of restriction pin.
