Detailed Description

Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar functions throughout.

The orientation shown in the drawings is not to be considered as limiting the scope of the invention, but merely as providing a reference to the preferred embodiments for an understanding of changes in the location or addition of numbers or structural simplifications to the product parts illustrated in the drawings.

The relation of "connected" between the components shown in the drawings and described in the specification can be understood as fixedly connected or detachably connected or integrally connected; may be directly connected or connected through an intermediate, and those skilled in the art will understand that the connection relation may be substituted in a suitable manner for the different embodiments according to the specific situation, and the orientations shown in the drawings may be direct contact or contact through another feature therebetween; above may be directly above and obliquely above, or it simply means above the other; other orientations may be understood by analogy.

The technical scheme and the beneficial effects of the invention are clearer and clearer by further describing the specific embodiment of the invention with the accompanying drawings of the specification; and are intended to be illustrative of the invention and not to be construed as limiting the invention.

As shown in fig. 1-2, it is preferable to provide a toner cartridge contact wire structure for the embodiment of the present invention, which includes a cavity formed by combining a main body 1 and a cover body 2; one side of the main body 1 is provided with a gear set 3, and the gear set 3 is connected with and drives each roller body 4; the roller body 4 is connected to a contact wire 5, and the contact wire 5 includes a spiral elastic contact portion 51, an intermediate lever 52, and a curved elastic printer contact portion 53.

The contact lead 5 is formed into a whole by bending an elastic lead. A buffer curved hook 54 is provided between the intermediate lever 52 and the spiral elastic contact portion 51. The buffer bent hook 54 effectively relieves the swing influence of roller rotation on the middle rod 52 during printing, so that the contact is dynamically stable.

The curved resilient printer contact portion 53 includes a first contact arm 531 and a second contact arm 532, the second contact arm 532 being connected to one end of the intermediate lever. The number of the contact wires 5 is plural. The utility model discloses can effectively improve contact stability and commonality, stable connection under the contact developments, simple structure, equipment are swift, and effectively reduce the cost of manufacture. Therefore, the product has excellent economical and technical properties.

While the invention has been described in terms of the preferred embodiments described above, there may be alterations, permutations, and equivalents, which fall within the scope of this invention; there may be many alternative ways of implementing the invention. It is therefore intended that the following appended claims be interpreted as including all such alterations, permutations, and equivalents as fall within the true spirit and scope of the present invention; it will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and modifications and substitutions based on the known art are intended to fall within the scope of the present invention, which is defined by the claims.
