[0033] Reference Figure 1 and Figure 2The present invention relates to a developing cartridge, comprising: a housing frame 100; and an electrode 200, including a mounting portion 210 connected to the housing frame 100. A deformable connecting portion 220 extends from the side of the mounting portion 210 away from the housing frame 100 along the Y-axis direction, and the deformable connecting portion 220 is suspended in mid-air.

[0034] The application of the above-mentioned developing cartridge has at least the following beneficial effects: the electrode 200 is connected to the housing frame 100 through the mounting part 210, and a deformable connecting part 220 extends out of the outer side of the housing frame 100. The deformable connecting part 220 is suspended, so that the deformable connecting part 220 can deform. When the developing cartridge is installed into the printing device, the rigid contact between the deformable connecting part 220 and the electrical contact part of the printing device is changed to a flexible contact, which avoids the wear or damage of the electrical contact part caused by rigid contact during the installation process, and ensures the printing quality of the printing device.

[0035] According to some embodiments of this utility model, the deformable connecting part 220 is designed in the shape of a "7", with the long side of the "7" suspended in the air, such as... Figure 2 As shown, in this embodiment, the electrode 200 is made of an elastic conductive material. The elastic conductive material can be a conductive metal, such as platinum, palladium, silver, copper, etc., or it can be a composite conductive plastic. In the composite conductive plastic, the plastic itself does not have conductivity and only acts as an adhesive. The conductivity is obtained by mixing conductive substances such as carbon black and metal powder into it. This elastic conductive material itself has a certain elasticity. After extending into a "7" shape, when the long side of the "7" is suspended, the deformable connecting part 220 can produce a certain deformation. When it comes into contact with the electrical contact part, it deforms, avoiding direct rigid contact with the electrical contact part and forming a certain buffer. At the same time, under the action of the elasticity of the motor 200 itself, the deformable connecting part 220 can always abut against the electrical contact part to ensure stable power supply.

[0036] In some other embodiments, the deformable connection 220 may also be made of a plastic conductive material, such as conductive clay. When it comes into contact with the electrical contact part, the deformable connection 220 deforms accordingly with the shape of the electrical contact part. During the process, the deformable connection 220 can always be in contact with the electrical contact part to ensure stable power supply.

[0037] According to some embodiments of the present invention, the housing frame 100 is provided with a positioning post 110 along the X-axis direction, and the mounting part 210 is provided with a mounting hole 230 that matches the positioning post 110. The positioning post 110 and the mounting hole 230 are used to cooperate for installation, and the positioning and assembly are carried out simultaneously, eliminating the separate positioning process and saving assembly time.

[0038] According to some embodiments of the present invention, it also includes a powder feeding roller and a conductor 300. The powder feeding roller is disposed inside the housing frame 100, and the conductor 300 is disposed on the housing frame 100 along the Y-axis direction with its first end 310 connected to the powder feeding roller. The second end 320 of the conductor 300 is connected to the mounting part 210. The power supply of the electrical contact part can be conducted to the powder feeding roller on the other side of the housing frame 100 through the conductor 300.

[0039] According to some embodiments of the present invention, the mounting part 210 is U-shaped, the first side of the U-shape extends into a deformable connecting part 220 along the Y-axis direction, the second side of the U-shape is connected to the second end 320 of the conductor 300, and the bottom edge of the U-shape is connected to the housing frame 100. In some other embodiments, other shapes can also be adopted according to the shape of the housing frame 100 to adapt to different specifications of the housing frame 100.

[0040] According to some embodiments of this utility model, the conductor 300 is a metal component.

[0041] According to some embodiments of the present invention, the electrode 200 and the conductor 300 are integrally formed components. By making the electrode 200 and the conductor 300 integrally formed components, assembly steps are reduced, assembly efficiency is improved, and assembly operations are simplified.

[0042] According to some embodiments of the present invention, it also includes a developing roller 400, which is hinged to the housing frame 100. The housing frame 100 is provided with side covers 500 on both sides along the Y-axis direction, and the two ends of the developing roller 400 are hinged to the side covers 500.

[0043] According to some embodiments of the present invention, the deformable connecting part 220 is suspended on the side of the side cover 500 away from the housing frame 100.

[0044] It should be noted that in this specification, terms such as "one embodiment", "some embodiments", "basic embodiment", and "extended embodiment" may be used to describe several embodiments of the present invention, and the specific features, structures, materials or characteristics of the several embodiments may be combined in accordance with the principles and spirit of the present invention.

[0045] Although some embodiments of the present invention have been shown and described in this specification, the present invention should not be limited to the above embodiments. As long as they achieve the technical effects of the present invention by the same or equivalent means, any changes, modifications, equivalent substitutions and equivalent variations of these embodiments within the spirit and principles of this disclosure, without departing from the principles and purpose of the present invention, should be included within the scope of protection of this disclosure and should be considered to fall within the protection scope of the present invention.
