Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present utility model, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0017] Example 1

[0018] According to an embodiment of the utility model, Figure 1The structure of a toner cartridge of the utility model is schematically shown. As shown in the figure, the toner cartridge 1 mainly includes a power receiving end 11 located at one end of the toner cartridge, which is used to receive the power of the printer; a drive receiving end 12 located at the other end of the toner cartridge, which is used to receive the driving force of the printer; and a developing roller 13, which is located at the front end of the toner cartridge along the installation direction of the toner cartridge and cooperates with the printer to complete the developing operation. There is a chip mounting position 2 on the right side of the upper surface of the toner cartridge, which can be used to install and fix the chip. The chip mounting position 2 is located on the right side of the middle position 15 of the toner cartridge, that is, the chip mounting position is located on the surface of the toner cartridge near the drive receiving end. The electrical connection area and the chip mounting position are connected by conductive material, and there is a chip mounting position terminal 21 in the chip mounting position. The chip has contacts and a memory, and the memory stores information related to consumables. After the chip is successfully installed in the chip mounting position, the chip contacts can be electrically connected to the chip mounting position terminals 21 in sequence. The chip mounting position terminals 21 are arranged along the installation direction of the toner cartridge. The chip installation method is to install the chip in an inverted manner, from the upper surface of the toner cartridge to the lower surface of the printer, to the chip installation position. When the toner cartridge is placed horizontally to install the chip, the chip contacts are downward. The left position at the rear end of the toner cartridge contains an electrical connection area 3, and the electrical connection area 3 is located on the left side of the middle position 15 of the toner cartridge. The electrical connection area contains contact points, which are located at the rear end of the toner cartridge near the power receiving end. After the toner cartridge is installed to the printer along the direction shown in the figure, the contact points of the electrical connection area are used to contact the contact pin structure on the rear cover of the printer to achieve electrical connection. The electrical connection area 3 can be a substrate with contacts, or it can be other structures such as conductive iron sheets, conductive plastics, etc. where each terminal is independently set. A conductive material 14 is laid between the chip installation position 2 and the electrical connection area 3 on the upper surface of the toner cartridge to achieve electrical connection between the chip installation position terminal 21 and the contact points of the electrical connection area. The conductive material can be a conductive iron sheet, conductive plastic, etc.

[0019] When the conductive material 14 is a conductive iron sheet, Figure 2 The structure in the chip mounting position 2 is given as an example. As shown in the figure, the chip mounting position is a slot-shaped structure that can accommodate and fix the chip. There is a chip mounting position terminal 21 in the mounting position. The terminal is a conductive iron sheet 14 with a tilting portion 22, and the terminal 21 is connected to the electrical connection area 3 on the box body through the conductive iron sheet 14. The tilting portion 22 of the terminal has a certain elasticity and can be pressed downward. In the non-pressure state, the tilting portion 22 is in a normal tilting state, such as Figure 2As shown in the figure, under pressure, the tilting portion 22 will move downward, stick to the bottom surface of the chip mounting position 2, and maintain an upward elastic force. There is also a cover structure (not shown in the figure) above the chip mounting position 2 to protect and fix the chip. When installing the chip, the chip is placed on the chip mounting position 2, and the contacts of the chip correspond to the tilting portions 22 of the mounting position terminals 21. After closing the cover of the chip mounting position 2, the cover will squeeze the chip, and the chip will further squeeze the tilting portion 22 of the terminal. The tilting portion 22 of the mounting position terminal 21 is in close contact with the contacts of the chip to ensure the stability of the electrical connection.

[0020] The conductive material 14 for electrical connection between the chip mounting position 2 and the electrical connection area 3 may be conductive plastic. A groove is left on the surface of the toner cartridge 1 manufactured by the injection molding process between the chip mounting position 2 and the electrical connection area 3, and then the conductive plastic is filled in the groove to achieve electrical connection between the chip mounting position terminal 21 and the contact point of the electrical connection area. In this embodiment, one of the chip mounting position terminal 21 and the chip may be a resilient structure to ensure good contact between the chip and the mounting position during installation.

[0021] Figure 3 , Figure 4 The schematic diagram of the arrangement of the contacts after the chip is installed and the contacts in the electrical connection area of ​​the toner cartridge in the first embodiment. Figure 3 , Figure 4 As shown, there is a connection line 33 between the electrical connection area 3 and the chip 4, the contact points in the electrical connection area 3 are arranged along the length direction of the toner cartridge 1, and the chip contacts are arranged along the installation direction. The leftmost contact point in the electrical connection area 3 along the toner cartridge installation direction 16 is the data terminal 31, and the rightmost contact point is the ground terminal 32. The chip contacts are arranged as follows: Figure 3 , Figure 4 Two situations, Figure 3 The front end of the middle chip along the toner cartridge installation direction 16 is a data terminal 41, and the rear end is a ground terminal 42; Figure 4 The front end of the middle chip along the carbon powder installation direction is a ground terminal 42, and the rear end is a ground terminal.

[0022] The chip contacts and the electrical connection area 3 shown in the diagram of the present invention have four contact contacts, namely a data terminal, a ground terminal, a power terminal and a clock terminal. However, the number of terminals does not limit the present invention. Cases where the number of terminals is less than or more than four should also be within the protection scope of the present invention.

[0023] In addition, it should be noted that Figure 3 , Figure 4 It is only for illustrating the arrangement direction of the chip contacts and the contact points of the electrical connection area 3 after the chip is successfully installed. On the actual toner cartridge, the chip and the electrical connection area 3 are not in the same plane.

[0024] By setting the chip on the upper surface of the toner cartridge 1 on the right side along the installation direction 16, after the chip is successfully installed, the chip does not protrude from the upper surface of the toner cartridge, which can solve the problem of inconvenience in chip operation caused by placing the chip on the left side of the toner cartridge. It is beneficial for the operator to install and remove the chip, and the chip installation position 2 prevents the chip from protruding from the upper surface of the toner cartridge and being exposed, and can also protect the chip.

[0025] Example 2

[0026] Figure 5 This is a schematic diagram of the second embodiment. As shown in the figure, the difference between this embodiment and the first embodiment lies in the electrical connection method between the chip mounting terminal 21 and the contact contact of the electrical connection area. In this embodiment, no conductive iron sheet and conductive plastic are laid between the electrical connection area on the surface of the toner cartridge and the chip mounting position, but they are connected by a cable 17. The two ends of the cable 17 are connected to the contacts at both ends by welding or other connection methods. The chip mounting terminals are arranged along the width direction of the toner cartridge.

[0027] Using the cable 17 to electrically connect the contacts at both ends is more conducive to cost saving and does not require complicated processing and manufacturing processes.

[0028] Example 3

[0029] In this embodiment, Figure 6 As shown, the difference from the above embodiment is that the chip mounting position 2 is on the surface of the toner cartridge 1. The chip mounting position terminals 21 are arranged along the length direction of the toner cartridge. The specific arrangement of the chip contacts and the contact contacts in the electrical connection area 3 is as follows: Figure 7 shown. Figure 7 There is a connecting line 33 between the electrical connection area 3 and the chip 4. The left contact of the electrical connection area 3 along the toner cartridge installation direction is the data terminal 31, and the right contact is the ground terminal 32; the left contact of the chip along the toner cartridge installation direction is the ground terminal 42, and the right contact is the data terminal 41.

[0030] Since the length of the toner cartridge in the length direction 18 is relatively long and the width of the toner cartridge in the installation direction 16 is relatively narrow, arranging the chip contacts along the toner cartridge length direction 18 can make it more convenient to place the chip.

[0031] For the above embodiments, it should be noted that the middle position 15 of the toner cartridge is located between the power receiving end and the drive receiving end. It is an auxiliary line made to conveniently display the position of the chip on the toner cartridge and may not be present in the actual object.

[0032] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
