Description

Unidirectional attaching plug

The utility model relates to the appliance switch technical field, particularly a kind of unidirectional attaching plug.

In the daily life, employed single detachable plug, owing to the heterogeneity of producing and other reason pin be not loosening be exactly tension, no matter and wiring inconvenience was pine or tension, they all have a lot of drawbacks.If pin is loose excessively, can make that insert 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 by the following scheme.It comprises pin left and right sides inserting handle; Inserting handle lid and spring.The through hole that it is characterized in that pin one end embeds on the interior fixed leg of inserting handle, and is fixing simultaneously inserting handle lid and pin by screw.Middle part at inserting handle is provided with support arm, link together by axle or universal joint between the support arm, inserting handle can drive pin by the cooperation between the support arm and rotate front and back together, change the width between two pins, be provided with the spring that is used to limit the pin width in the upper and lower of 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 unidirectional attaching plug.

As shown in Figure 1, this unidirectional attaching plug, it comprises pin 1 left and right sides inserting handle 2; Inserting handle lid 3 and spring 4, the through hole that it is characterized in that pin 1 one ends embeds on the fixed leg in the inserting handle 2, fixing simultaneously by screw 5 inserting handle lid 3 and pin 1, be provided with support arm 6 at the middle part of inserting handle 2, link together by axle or universal joint between the support arm 6, inserting handle 2 can drive pin 1 by the cooperation between the support arm 6 and rotate front and back together, changes the width between two pins 1, is provided with the spring 4 that is used to limit pin 1 width in the upper and lower of two inserting handles 2.

Claims

1, a kind of individual event attaching plug is characterized in that 1, inserting handle branch left and right sides two parts, and the front portion of inserting handle is established pin respectively, the inboard, middle part is established support arm respectively, connect with axle or universal joint between two support arms, left and right sides inserting handle inside lower end is established spring base, and spring base is established spring.

2, the individual event attaching plug of saying according to claim 1 is characterized in that, at the inner top side equipment spring base of left and right sides inserting handle.

3, according to claim 1 or 2 said individual event attaching plugs, it is characterized in that: on spring base, establish convex, on spring base, can open a suitable longitudinally ditch, so that the spring of other type is installed.
