The safe and reliable operation of the many switch cubicles of quality of draw out switchgear cabinet loop connector has very important effect, and whether secondary line socket connector contact terminal pressure is enough the important symbol of connector quality, it has determined that can drawer tolerate the impact of motor start-up electric current while moving, during oepration at full load, whether temperature rise is qualified, whether cause the main cause that plug burns, so adopt high reliability connector very necessary.
Summary of the invention
In order to overcome the deficiency of background technology, the utility model provides draw-out type low voltage switch cabinet secondary line plug assembly to address the above problem.
The technical solution of the utility model is: draw-out type low voltage switch cabinet secondary line plug assembly, comprise the cabinet wallboard of switch cubicle, on cabinet wallboard, by the back-up ring and the spring that are fixed on male plug headstock, male plug headstock is fixed, outside the cabinet wallboard of male plug headstock, in the end face of one end, solidify and connect some inserted sheets, male plug headstock is stretched out in inserted sheet one end, the other end is in the inner connecting secondary wire of male plug headstock, the other end of secondary wiring connects the public plug that solidifies the equal number in male plug headstock, the other end of public plug stretches out the counterbore end face of male plug headstock, the cylindrical end of stretching out of public plug is conical,
By back-up ring, be fixedly connected with female plug headstock with on the drawer panel of a relative side in cabinet wallboard, in female plug headstock, solidify the female that connects some quantity, the end face of female plug headstock counterbore is stretched out in female one end, the cylinder end face of extension has counterbore, counterbore edge is conical, female other end connecting secondary wire, and secondary wiring is solidificated in female plug headstock inside, the opposite side of secondary wiring connects the inserted sheet that is solidificated in female plug headstock other end, and the opposite side of inserted sheet stretches out the end face of female plug headstock.
The taper shape of described public plug cylindrical end, measure-alike with the conical angle at female counterbore edge, and counter bore hole diameters is greater than the conical end diameter of public plug.
Described some public plugs and some females, its quantity is with position is identical separately.
The counterbore of described male plug headstock, there is guiding groove in its edge, and its counter bore hole diameters is greater than female plug headstock outside diameter.
The utlity model has following beneficial effect: the elastic force by the contact of taper anchor ring and spring guarantees pressure, increased contact area, also guaranteed contact, and along with the increase of frequency of exposure, the conical surface of plug increases contact area and can be because of repeatedly using generation wearing and tearing and contact-making surface to contact better because repeatedly use, steel spring is avoided elastic failure and the accident of loose contact generation, tolerance overload current ability is strong, and one group of spring mechanism multiple circuits of can simultaneously pegging graft, simple in structure, dependable performance, guarantee that operational outfit quality safety is reliable.
accompanying drawing explanation:
Accompanying drawing 1 is structural representation of the present utility model.
In figure, 1-looks into sheet, 2-back-up ring, 3-cabinet wallboard, 4-spring, 5-male plug headstock, 6-secondary wiring, 7-public plug, the 8-groove that leads, 9-female plug headstock 10-female, 11-drawer panel.
embodiment:
