Description
Technical field
The utility model is related to appliance field, more particularly to a kind of easy plug for replacing pin.
Background technology
The use of present electronic product is more and more extensive, and the use of electronic product be unable to do without power supply, and power supply is provided
Electron product must just be connected electronic product and power supply using plug, it is well known that metal material is carried on plug
Pin, during the use of plug, because the effect of external force can be deformed upon or because caused in moist environment
Pin gets rusty, so as to cause the damage of pin, and after plug base pin on the market is broken now can only integral replacing plug, and
Except pin portion is all intact in plug, the waste of plug can be so caused, is particularly wall-mounted on power supply adaptor
After pin is broken, can only the entire power supply adaptor of integral replacing, cause unnecessary waste.
Utility model content
Based on this, it is necessary to for after the pin damage of plug must integral replacing entire plug the problem of, one kind is provided
The plug of pin is easily replaced, including：Housing, including the upper shell and lower housing being vertically connected with, the upper shell and the lower casing
Body is formed with an accommodating cavity；Jack is arranged on the upper shell, and the jack is from top to bottom through the upper shell, institute
The inner wall for stating jack is provided with internal thread；Wiring hole is arranged on the lower housing, under the jack runs through described from top to bottom
Housing is interconnected between the jack, accommodating cavity, wiring hole；Conducting wire, the conducting wire is through the wiring hole with being arranged on
Connector on the inside of the lower housing is connected with each other；Pin, the pin are provided with the internal thread phase with being set in the jack
The external screw thread of cooperation, the lower end of the pin offset with the connector, and the upper end of the pin passes through the jack toward extension
It stretches.
Pin is screwed in through the jack on upper shell in the accommodating cavity that upper shell is cooperatively formed with lower housing, is threaded directly into
Until pin lower end and connector offset, and pin offsets with connector and can be connected by connector with conducting wire, plug
At work, electric current passes to conductive connector by pin and passes to conducting wire again.The external screw thread on pin is arranged on setting
The internal thread put in jack is engaged, and pin is fixed on upper shell.By rotating pin, it may be convenient to install and tear open
Unload pin.
As one of which embodiment, connector is located at immediately below the jack.
Pin is straight, and pin is screwed in after jack, and the lower end of pin is also set immediately below jack, by connector
It puts immediately below jack, after pin screws in jack, pin can directly offset with connector so that plug interior structure is simple.
As one of which embodiment, fixed block is further included, the fixed block is arranged in the accommodating cavity, described solid
Determine to correspond to the jack position on block and be provided with the through hole for running through the fixed block from top to bottom, the pin is through described logical
Hole.
Pin through jack and then insertion fixed block in, pass through the cooperation between the through hole and pin on fixed block
Further fixed piece on earpiece so that the connection of pin and plug is more secured.
As one of which embodiment, through hole is internally provided with and the matched internal thread of external screw thread on the pin.
The jack on through hole and upper shell on fixed block on the same line, after pin screws in jack, continues to screw in logical
Kong Zhong, pin are connected through a screw thread with jack and through hole so that pin stronger can be connected on plug.
As one of which embodiment, pin is cylindrical-shaped structure.
Pin is cylindrical-shaped structure, so, pin side does not have sharp edges, will not be because of side when being inserted into socket
The friction of sharp edges and socket generates resistance, and pin can be made to be easier to be inserted into socket.
The setting of pin upper surface is fluted, and the groove extends transversely through the pin.
As one of which embodiment, pin lower face is cambered surface.
Pin lower face is cambered surface, so, pin surface does not have sharp edges, will not be because of surface when being inserted into socket

As one of which embodiment, the setting of pin upper surface is fluted, and the groove extends transversely through the pin.
Pin is cylinder, therefore pin surface is curved surface, when dismantling or pin be installed, when clamping pin, and stress
Area is small, is not easy to clamp, and therefore, a groove for extending transversely through pin is set on pin, and the bottom surface of pin is plane, this
Sample when clamping pin, can clamp on this plane, increase forced area, clamping when facilitating rotation pin to pin.
As one of which embodiment, connector is elastic piece.
Connector is for connection to pin and conducting wire, plays conductive effect, and connector with pin by offseting realization
Being electrically connected between pin and connector, if connector is elastic piece, after pin offsets with connector, elasticity occurs for elastic piece
The distance of connector and pin, is set smaller than the distance of pin insertion accommodating cavity by deformation, is so existed in pin and is processed
In the case of error, pin is long or too short can offset with connector.
As one of which embodiment, pin includes being accommodated in the connecting pin in the accommodating cavity with being located at outside housing
Insertion end, the area of section of the insertion end are more than the area of section of the connecting pin, are provided between connecting pin and insertion end
Step.
Insertion end area of section is more than connecting pin area of section, and when screwing in jack, only insertion section can screw in slotting pin
Hole so can guarantee the length that pin screws in, will not it is long will not be too short, not only can guarantee that pin can arrive to connection sheet, but also not
Pin can be should be to screw in long and damage connection sheet.
The principle, effect of the utility model are further illustrated with reference to above-mentioned technical proposal：
1. being provided with tapped jack on upper shell, it is arranged on the fixed block inside receiving cavity and corresponds to jack position
