Description
Technical field
A kind of spring formula of the utility model power current docking apparatus belongs to colliery power cable plug assembly technical field.
Background technology
What the electric equipment of China's coal-mine down-hole generally adopted at present is the attached cable interconnection system, in case the generator electric fault, difficult treatment; The queueing problem time is long, changes to be difficult for, and has increased downtime; Serious restriction the High-efficient Production in colliery, and be with into potential safety hazard; The tie point of cable or electric wire and electric equipment adopts cable connector usually; Be commonly called as the line nose; Again line nose and link terminal are linked together through bolt after cable and line nose be cold-pressed into one; The characteristics of doing like this are to connect reliably, connect the back electric equipment and promptly fix with cable, but wiring, the trouble of taking out stitches, time-consuming; This can't use in the occasion that much needs to connect fast; Particularly in the middle of the electric equipment of some blocking, assemblyization; Binding post is many and it is frequent to connect, tear open; Be sought after a kind of termination that can realize that lead connects fast, for the colliery minute to calculate output, every bull point clock functional failure of electromechanical time all is to the waste of output and the hidden danger of safety.
The utility model content
The utility model overcomes the deficiency that prior art exists, and technical problem to be solved is: the docking apparatus that provides a kind of power cable that is applied to the colliery electric equipment to connect fast.
For solving the problems of the technologies described above; The technical scheme that the utility model adopted is: a kind of spring formula power current docking apparatus comprises: female connectors and public connector, said female connectors are the tubular metal tube of hollow; The front end aperture of female connectors metal tube is littler than middle aperture; The inwall of female connectors metal tube is equipped with the sheet spring, and said spring is for being converted into jagged elastic sheet metal, and the sheet spring bends to tubulose along the female connectors inner wall of metal tube and installs; Said public connector is the cylindrical metal rod, and the public connector front end is the small cylinder that adapts with the female connectors inner wall of metal tube, and public connector rear end end face has axial hole.
Be provided with internal thread in the axial hole of said public connector rear end end face.
The material of said female connectors and public connector is the oxygen-free copper that electroplate is handled.
The beneficial effect that the utility model compared with prior art has is: the syndeton of the utility model through a kind of spring formula is ingenious to have realized that a power large current plug-in type connects; Have that volume is little, the conducting electric current is big, it is reliable, easy for installation, quick to connect; Be specially adapted to all kinds of cabinets or often need the electric equipment of connection, dismounting fast to use, greatly improve Safety of Coal Mine Production efficient.
Description of drawings
Below in conjunction with accompanying drawing the embodiment of the utility model is done further detailed explanation:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation of female connectors 1 in the utility model;
Fig. 3 is the structural representation of public connector 2 in the utility model;
Among the figure: 1 is that female connectors, 2 is that public connector, 3 is the sheet spring.
Embodiment
Shown in Fig. 1 to 3; A kind of spring formula of the utility model power current docking apparatus comprises: female connectors 1 and public connector 2, and said female connectors 1 is the tubular metal tube of hollow; The front end aperture of female connectors 1 metal tube is littler than middle aperture; The inwall of female connectors 1 metal tube is equipped with sheet spring 3, and said spring 3 is for being converted into jagged elastic sheet metal, and sheet spring 3 bends to tubulose along female connectors 1 inner wall of metal tube and installs; Sheet spring 3 also can be employed in the method that installs protrusion on female connectors 1 inner wall of metal tube additional and realize, sheet spring 3 can make female connectors 1 be connected reliably with public connector 2.
Said public connector 2 is the cylindrical metal rod; Public connector 2 front ends are the small cylinder that adapts with female connectors 1 inner wall of metal tube; Public connector 2 rear end end faces have axial hole; Be provided with internal thread in the axial hole of public connector 2 rear end end faces, cable heart yearn the end of a thread and line nose are fixed by bolts to the line nose in the axial hole of public connector 2 rear end end faces after being cold-pressed into one again, also can cable heart yearn the end of a thread directly be welded in the axial hole of public connector 2 rear end end faces.
The material of said female connectors 1 and public connector 2 is the oxygen-free copper that electroplate is handled, and has both satisfied external condition abominable under the coal mine, can reach big conducting electric current again.
When mounted; Above-mentioned female connectors 1 can be through bolt to the connection copper bar of contactor; Above-mentioned public connector 2 connects cable; The power connecting portion tap of an electric component in the mining like this electric equipment just can directly connect through plugging, and the fast and reliable that can realize cable connects or pulls down.
Combine accompanying drawing that the embodiment of the utility model has been done detailed description above; But the utility model is not limited to the foregoing description; In the ken that those of ordinary skills possessed, can also under the prerequisite that does not break away from the utility model aim, make various variations.For example, other modes can be adopted with being connected also of cable heart yearn the end of a thread in 2 rear ends of the public connector in the utility model.
