Abstract
The invention provides a magnetic roller electrifying structure. The magnetic roller with the electrifying structure is composed of a magnetic core, an aluminum sleeve, and a magnetic roller support. The structure is characterized in that: a segment of a relatively thin prolonged aluminum pipe is arranged on a conductive terminal of the aluminum sleeve; the edge of the prolonged aluminum pipe is provided with a recessed annular slide way; the prolonged aluminum pipe communicates with a conductive steel piece through a conductive contact pin. In the magnetic roller electrifying structure provided by the invention, the aluminum sleeve of the magnetic roller contacts the conductive contact pin through the prolonged aluminum pipe, the conductive contact pin contacts the conductive steel piece, and finally the aluminum sleeve communicates with a magnetic roller power supplying interface on a printer controlling panel. The magnetic roller electrifying structure is advantaged in simple structure, low production cost, lasting and stable application, and easy installation.
Description
Technical field
The present invention relates to Se drum for laser printer structural design field, be specially a kind of magnetic roller energized structural.
Background technology
At present, traditional magnetic roller mainly is comprised of magnetic core, aluminium cover, magnetic roller support and conductive filament with the frosted coating.The aluminium cover is enclosed within on magnetic core, and magnetic roller support is arranged on the conducting end of aluminium cover.One end of conductive filament is stuck between aluminium cover and magnetic roller support, and the tinsel that the other end is spring-like with the conduction steel disc, contact, and the conduction steel disc is communicated with the magnetic roller power supply interface on the printer control panel.
Can find out, tradition magnetic roller is powered by conductive filament, there is following shortcoming in this magnetic roller energized structural of using conductive filament: 1) unstable: conductive filament is thinner, and in installing and using process, easily distortion even fractures, and causes and conducts electricity steel disc and contact unstable; 2) be difficult for to install: because of conductive filament more fragile, when conductive filament or magnetic roller are installed, must be very careful, indeformable to guarantee conductive filament, this has just brought inconvenience to installment work.
Summary of the invention
The objective of the invention is for tradition is the deficiency that magnetic roller aluminium overlaps power supply mode by conductive filament, proposes a kind of new magnetic roller energized structural.
To achieve these goals, developed a kind of magnetic roller energized structural.Adopt the magnetic roller of this energized structural only to be formed by magnetic core, aluminium cover, magnetic roller support, and in aluminium cover conducting end the prolongation aluminum pipe with a section slightly thin, extend the edge of aluminum pipe with recessed circular slideway; Magnetic roller support Design is with the plastic tube at major diameter edge slightly.Extend aluminum pipe and be communicated with the conduction steel disc by conductive pin, conductive pin is made by the elastic conduction metal material, and an end is with the collar.In addition, for fixing conductive pin, the draw-in groove place that special design is installed the magnetic roller at the toner cartridge baffle plate reserves conductive pin jack and conductive pin collar stationary shaft, and the conductive pin of installing by the conductive pin jack just with tangent contact of recessed circular slideway of prolongation aluminum pipe.
While assembling this magnetic roller, at first magnetic core is injected to the aluminium cover, magnetic core " D " word end overlaps conducting end towards aluminium; Then magnetic roller support is arranged on to aluminium cover conducting end.When the magnetic roller is installed, at first magnetic roller conducting end is aimed to the magnetic roller draw-in groove place of toner cartridge baffle plate by entering, then conductive pin is injected to the conductive pin jack on baffle plate, and press by tweezers the recessed circular slideway that the conductive pin collar pushes the conductive pin bending to extend aluminum pipe afterwards, finally by tweezers, the conductive pin collar is enclosed within on conductive pin collar stationary shaft.
In this magnetic roller energized structural, magnetic roller aluminium cover contacts with conductive pin by extending aluminum pipe, and conductive pin contacts with the conduction steel disc again, finally with the magnetic roller power supply interface on the printer control panel, is communicated with.
That magnetic roller energized structural provided by the invention has advantages of is simple in structure, low cost, use lasting stability, easily install.

Embodiment
The present invention proposes a kind of magnetic roller energized structural, adopt the magnetic roller of this energized structural only to be formed by magnetic core, aluminium cover, magnetic roller support (2).As shown in Figure 2, aluminium cover conducting end, with the prolongation aluminum pipe (1) of a section slightly thin, extends the edge of aluminum pipe (1) with recessed circular slideway (11).As shown in Figure 3, magnetic roller support (2) is designed to the plastic tube at major diameter edge slightly.Extend aluminum pipe (1) and be communicated with conduction steel disc (5) by conductive pin (3), as shown in Figure 4, conductive pin (3) is made by the elastic conduction metal material, and an end is with the collar (31).In addition, as shown in Figure 5, for fixing conductive pin, the draw-in groove place that special design is installed the magnetic roller at toner cartridge baffle plate (4) reserves conductive pin jack (41) and conductive pin collar stationary shaft (42).And proper tangent contact of recessed circular slideway (11) with extending aluminum pipe (1) of the conductive pin (3) of installing by conductive pin jack (41).
As shown in Figure 1, Figure 7 shows, when the magnetic roller is installed, at first magnetic roller conducting end is aimed to the magnetic roller draw-in groove place of toner cartridge baffle plate (4) by entering, then conductive pin (3) is injected to the conductive pin jack (41) on baffle plate (4), and press after the collar (31) makes conductive pin (3) crooked and push the recessed circular slideway (11) that extends aluminum pipe (1) by tweezers, finally by tweezers, the collar (31) is enclosed within on conductive pin collar stationary shaft (42).
As shown in Fig. 1, Fig. 6 and Fig. 7, in this magnetic roller energized structural, magnetic roller aluminium cover contacts with conductive pin (3) by extending aluminum pipe (1), and conductive pin (3) contacts with conduction steel disc (5) again, finally with the magnetic roller power supply interface on the printer control panel, is communicated with.
