Description

Ink box chip, ink box and ink-jet printing equipment

Technical Field

The present invention relates to the technical field of inkjet printing, and in particular, to an ink cartridge chip, an ink cartridge having the same, and an inkjet printing apparatus mounted with the same.

Background

The printing equipment is used as common office equipment, great convenience is provided for modern office, the common printing equipment is divided into ink-jet printing equipment and laser printing equipment, and the ink-jet printing equipment uses an ink box containing ink as a consumable container to jet the ink to paper so as to form characters or patterns to be printed on the paper; the laser printing device uses a toner cartridge containing toner as a consumable container to form text or patterns on a medium to be printed.

Referring to fig. 1, a conventional color inkjet printing apparatus has a housing 11, and the inkjet printing apparatus shown in fig. 1 omits a pallet of the housing 11. The housing 11 is provided with a movement 12 of the ink jet printing apparatus and with a slide along which a carriage 14 reciprocates under the drive of a motor (not visible in fig. 1). A main control circuit board (not visible in fig. 1) is provided in the carriage 14, and communicates with the movement 12 through the flat cable 13.

The carriage 14 is detachably provided with a plurality of ink cartridges 15, and different ink cartridges 15 contain different colors of ink. The structure of the ink cartridge 15 is shown in fig. 2. The ink cartridge 15 has a cartridge body 16, the cartridge body 16 encloses a chamber for accommodating ink, an ink outlet 17 is provided at the lower end of the chamber, and ink in the chamber flows out through the ink outlet 17 and is supplied to an ink supply needle of the carriage 14.

A chip 18 is mounted on the outer wall of the case 16 of the ink cartridge 15, the chip 18 having a substrate provided with a plurality of connection terminals 19 on one side thereof for electrical connection with contact pins on the carriage 14. The other side of the substrate is provided with a memory (not visible in fig. 2), typically a non-volatile memory, such as an EEPROM or FLASH, which stores information related to the ink cartridge, including variable information, which is information that is continuously variable with the printing operation, such as information of the ink margin, the printing duration, the number of printing sheets, etc., and invariable information, which is information that is not variable with the printing operation, such as the type of the ink cartridge, the type of the applicable inkjet printing device, the color of the ink, etc.

After the ink cartridge 15 is mounted to the carriage 14 of the ink jet printing apparatus, the ink jet printing apparatus powers up the chip 18 and reads data stored in the memory of the chip 18 to determine whether the type of the ink cartridge 15 is appropriate, whether the amount of ink remaining in the ink cartridge 15 is sufficient, and the like. The ink jet printing apparatus can execute a print job only after it is judged that the type of the ink cartridge 15 is proper and that there is sufficient ink in the ink cartridge 15.

Referring to fig. 3, a conventional ink cartridge chip 18 has 5 connection terminals 21, 22, 23, 24, 25,5 connection terminals including a power terminal, a ground terminal, a clock terminal, a data terminal, and a chip select terminal, respectively, provided on one surface of a substrate 20, and typically, the distance between the ground terminal 25 and the other connection terminals is large.

Referring to fig. 4 and 5, the carriage 14 has a plurality of carriage units, for example, one carriage unit 51, each of the ink cartridges 15 of each color corresponds to one carriage unit, and the plurality of carriage units have the same configuration, and a carriage unit 51 will be described as an example. The carriage 14 is further provided with a plurality of stylus holders 36, and the carriage unit 51 is provided with a plurality of styli, for example, 5 styli, arranged in two rows, namely, upper and lower, on the stylus holder 36, two styli at both ends of the upper first row being styli 41, 44, respectively, and two styli at both ends of the lower second row being 45, 49, respectively. The plurality of contact pins of the carriage unit 51 are in one-to-one correspondence with the plurality of connection terminals on the chip 18, and each contact pin is in contact with and electrically connected to a corresponding connection terminal.

A main control circuit board 33 is arranged behind the carriage 14, a plurality of contacts 34 are arranged on the main control circuit board 33, a plurality of contact pins 38 are also arranged on one side of the contact pin frame 36 close to the main control circuit board 33, the contact pins on two sides of the contact pin frame 36 are in one-to-one correspondence, and two contact pins corresponding to each other are electrically connected. The contact pins 38 near the main control circuit board 33 abut against the contacts 34 on the main control circuit board 33 and make electrical connection. The main control circuit board 33 also has a control chip and a detection circuit (not shown) for communicating with the chips 18 on the plurality of cartridges of different colors.

However, since all the connection terminals on the cartridge chip are disposed on the same surface and are in electrical contact with the plurality of contact pins on the side of the contact pins holder 36 of the carriage 14 near the cartridge, including one ground terminal, the distance between the ground terminal and the other four connection terminals is large, and the ground terminal is disposed on the substrate 20 near the ink outlet 17, when the cartridge is mounted or removed, a large equivalent resistance is generated between the ground contact pins on the ink jet printing apparatus and the ground terminal of the substrate 20 once ink or other foreign matter falls on the ground terminal, thereby causing the voltage of the other connection terminals on the substrate 20 except the power terminal to float down.

For example, before no ink drops to the ground terminal, the low level of the clock terminal CLK is 0V, the high level is 3.3V, once the ink drops to the ground terminal, the equivalent resistance formed by the ink is very large, and the voltage division to other connection terminals may be as high as 0.5V, at this time, the low level of the clock terminal CLK becomes-0.5V, the high level becomes 2.8V, and since the memory directly receives the signal output by the clock terminal CLK, the memory will be damaged after the signal after the voltage reduction is input to the memory. Similarly, if the high and low signals of the data terminal DAT do not coincide with the standard level signals, an error in the communication data may be caused, affecting the communication between the inkjet printing apparatus and the memory.

On the other hand, since the distance between the ground terminal and other connection terminals is large, the area of the substrate 20 is large, increasing the production cost of the substrate 20.

In addition, the contact pins on the contact pin frame may extend into the shell of the ink box, so that the situation has various reasons, namely the size of the ink box chip is not matched with the shell of the ink box, and the distance from the lower edge of the ink box chip to the shell is too large; or because the shell of the ink box is cooled and contracted excessively after injection molding, a gap appears between the lower positioning column of the ink box chip and the ink box shell, or the welding of the ink box chip is poor, the ink box chip falls off during installation, and the like. Because the lower edge of the contact pin is perpendicular to the pulling-out direction of the ink box, the situation occurs that the user can not pull out the ink box any more, and when the ink box needs to be replaced or the ink jet printing equipment needs to be maintained, the ink box is difficult to be singly taken out, but the contact pin frame fixing plate, the contact pin frames with all colors and the ink box need to be simultaneously taken out, the chip main control board is taken out, and then the buckle of the contact pin frame is released, so that the ink box and the contact pin frames can be simultaneously taken out. If the ink box is forcibly pulled out of the printing carriage, the contact pin and the contact pin frame can be easily carried out of the printing carriage at the same time, and the ink-jet printing equipment is damaged. Once the stylus holder or stylus is damaged, the inkjet printing device will not work, affecting inkjet printing operation.

Detailed Description

First embodiment:

the ink jet printing apparatus of this embodiment is provided with an organism, a print carriage is formed in the organism, referring to fig. 6 and 7, the ink cartridges 100 are detachably mounted in the print carriage, each ink cartridge 100 has a cartridge body 110, the cartridge body 110 encloses a cavity for containing ink, an ink outlet 118 communicating with the cavity is provided below the cavity, and the ink in the cavity can flow out through the ink outlet 118. A handle 112 is provided at the upper end of the case 110, and preferably, the handle 112 is an elastic handle that can be pressed and elastically deformed. Further, an ink cartridge chip 130 is detachably mounted on one front wall of the lower end of the cartridge body 110.

The carriage is provided with a stylus holder 160, and the main control circuit board 150 and the ink cartridge 100 are respectively disposed on both sides of the stylus holder 160. The contact pins are provided at both sides of the contact pin holder 160, respectively, so that the ink cartridge chip 130 is in contact with the contact pins 161 at the first side of the contact pin holder 160, and the main control circuit board 150 is in contact with the contact pins at the second side of the contact pin holder 160. The contact pins on two sides of the contact pin holder 160 are arranged in a one-to-one correspondence, and the corresponding two contact pins are electrically connected with each other.

Referring to fig. 8 to 12, the cartridge chip 130 has a substrate 131, the substrate 131 being substantially rectangular, four communication terminals 132 being provided on a first surface of the substrate 131, and a ground terminal 136 being provided on a second surface of the substrate 131. In this embodiment, the first surface and the second surface are respectively located on two opposite sides of the substrate 131. As can be seen from fig. 11 and 12, the first surface of the substrate 131 is a surface substantially parallel to the front wall 111 of the ink cartridge 100, and is exposed to the front wall 111 of the ink cartridge 100 after the ink cartridge chip 130 is mounted to the cartridge body 110. The second surface of the substrate 110 is a surface closer to the rear wall of the ink cartridge 100, and is not exposed to the front wall 111 of the ink cartridge 100 after the ink cartridge chip 130 is mounted to the cartridge body 110, and thus, the ground terminal 136 is not exposed to the surface of the ink cartridge 100.

The four communication terminals 132 on the first surface are a power supply terminal VCC, a clock terminal CLK, a data terminal DAT, and a chip select terminal CS, respectively, the four communication terminals 132 are arranged in two rows up and down, and the four communication terminals 132 are each in direct contact with the contact pins 161 of the first side of the contact pin holder 160, i.e., the contact pins 161 abut on the four communication terminals 132. In addition, a memory is further disposed on the substrate 131, and the four communication terminals 132 and the ground terminal 136 are electrically connected to the memory, so as to provide power and clock signals for the operation of the memory. It should be noted that, in this embodiment, fewer or more communication terminals may be provided on the first surface, for example, a battery may be provided on the cartridge chip 130, or power may be taken from the clock terminal CLK and the chip selection terminal CS, so that the power supply terminal VCC may be removed; alternatively still, the cartridge chip 130 may recognize whether the current communication session has ended based on the content of the communication, so that the chip select terminal CS may be removed, and the present embodiment does not limit the number of communication terminals on the first surface. In addition, as can be seen from fig. 10, after the cartridge chip 130 is mounted on the cartridge 100, as can be seen from fig. 8, all the communication terminals 132 and the ground terminals 136 of the substrate 131 are located on the same side of the center line L1 of the ink outlet 118, so that the area of the substrate 131 can be made smaller.

The base plate 131 is disposed below the handle 112, a plurality of limiting members 138 are disposed on the front wall 111 of the ink cartridge 100, and a plurality of limiting grooves 133 are correspondingly disposed on the base plate 131, and each limiting member 138 is matched with one of the limiting grooves 133. When the cartridge chip 130 is mounted to the cartridge body 110, the substrate 131 is fixed at a position designated by the front wall by the matching of the plurality of stopper pieces 138 and the plurality of stopper grooves 133, and displacement of the substrate 131 on the front wall is avoided, thereby ensuring accurate contact of the four communication terminals 132 with the contact pins 161.

Since the ground terminal 136 is disposed on the second surface of the substrate 131, the ground terminal 136 does not directly contact the contact pins of the contact pin holder 160. In order to solve the problem that the ground terminal 136 receives the ground level output from the inkjet printing apparatus, the present embodiment provides a conductive connecting member 140, and the conductive connecting member 140 is made of metal and has a certain elasticity. Referring to fig. 12, the conductive connection member 140 includes a first abutting section 141, a connection section 142, and a second abutting section 143, wherein the connection section 142 is located between the first abutting section 141 and the second abutting section 143.

Referring to fig. 13, the lower end of the first abutting section 141 is a free end, and an elastic portion 145 is disposed on the free end, wherein the elastic portion 145 is a first end of the conductive connecting member 140, that is, the first end of the conductive connecting member 140 is the free end of the first abutting section 141, and the elastic portion 145 abuts against the ground terminal 136. As can be seen from fig. 13, the elastic portion 145 is curved, and the elastic portion 145 can be elastically deformed, so as to facilitate the installation of the conductive connecting member 140. In addition, the first abutting section 141 is further provided with an extension section 146, and the extension section 146 is located above the elastic portion 145 and between the connection section 142 and the elastic portion 145. In the present embodiment, the extension section 146 extends in a horizontal direction, that is, the extension direction of the extension section 146 is perpendicular to the first surface of the substrate 131.

When the conductive connecting member 140 is mounted to the ink cartridge 100, the first abutting section 141 is inserted into the side of the substrate 131 near the front wall of the ink cartridge 100, and in order to facilitate the mounting of the first abutting section 141, a recess groove 115 is provided in the front wall 111, the recess groove 115 is recessed from the surface of the front wall 111 into the cartridge body 110 to form a recessed groove, and the lower end of the first abutting section 141 is inserted into the recess groove 115. In this way, the lower end of the first abutment section 141 is not exposed to the outer surface of the ink cartridge 100.

Referring to fig. 14 and 15, a main control circuit board 150 of the inkjet printing apparatus is disposed on a second side of the stylus holder 160, a plurality of contacts 151, such as ground contacts, are disposed on a surface of the main control circuit board 150 adjacent to the stylus holder 160, and the second abutting section 143 is electrically connected to the ground contacts. Specifically, the lower end of the second abutting section 143 is a free end, and forms a second end of the conductive connecting member 140, and the second end is provided with an elastic portion 147, the elastic portion 147 is curved, and the elastic portion 147 can elastically deform, and the elastic portion 147 abuts against the ground contact. In this way, the conductive connection member 140 realizes electrical connection between the ground terminal 136 on the substrate 131 and the ground contact of the main control circuit board 150, so that the level of the ground terminal 136 on the substrate 131 and the level of the ground contact of the main control circuit board 150 are kept identical, thereby keeping the ground level of the ink cartridge chip 130 and the ground level of the inkjet printing apparatus identical. In addition, in the present embodiment, there is no electrical connection between the first surface of the substrate 131 and the ground contact pin of the inkjet printing apparatus, that is, the first surface of the substrate 131 is electrically insulated from the ground contact pin of the inkjet printing apparatus.

In this embodiment, the conductive connecting member 140 spans the first side and the second side of the stylus holder 160, specifically, the first abutting section 141 is located on the first side of the stylus holder 160, the second abutting section 143 is located on the second side of the stylus holder 160, and the connecting section 142 is located above the stylus supporting portion 162 of the stylus holder 160. The stylus holder 160 is provided with a connection part 163 at one side of the stylus supporting part 162, the connection part 163 is close to the second side of the stylus holder 160, and the main control circuit board 150 is located below the connection part 163. In this way, the ground terminal 136 does not make electrical contact with any contact pin on the carriage on the side facing the substrate 131 when the ink cartridge is mounted to or removed from the ink jet printing apparatus, and the ground terminal 136 makes electrical contact with only a contact pin on the carriage on the side facing away from the substrate 131 or directly with a ground contact on the ink jet printing apparatus main control circuit board 150 by the connection action of the conductive connection member 140.

A mounting gap 164 is formed between the stylus supporting portion 162 and the connecting portion 163, and the second abutting section 143 may pass through the mounting gap 164 and be inserted between the main control circuit board 150 and the stylus supporting portion 162. Since the contact pins on both sides of the contact pin holder 160 are mounted on the contact pin supporting part 162, the contact pins on the second side of the contact pin supporting part 162 can be connected with the contacts on the main control circuit board 150. When the second abutment section 143 is inserted between the main control circuit board 150 and the stylus support 162, the second abutment section 143 will be clamped between the stylus and the ground contact. Since the contact pins protrude outward from the contact pins on the second side of the contact pin supporting portion 162, the contact pins support the elastic portion 147 and firmly abut the elastic portion 147 against the ground contact, in conformity with the shape of the elastic portion 147.

The conductive connection 140 needs to be secured to the ink cartridge 100 before the ink cartridge 100 is mounted to a printer carriage. In order to achieve the fixation of the conductive connecting member 140, the present embodiment is provided with a protrusion 120 on the front wall 111 of the ink cartridge 100, the protrusion 120 being located below the handle 112 but above the substrate 131. The protruding portion 120 protrudes outwards from the front wall 111 of the case 110, and a fastening portion 121 is provided on an outer wall of the protruding portion 120, and the fastening portion 121 includes two fasteners 122. Referring to fig. 13, each fastener 122 has a cantilever 123, and a catch 124 is provided at the free end of the cantilever 123, in this embodiment, the catches 124 of two fasteners 122 are oriented differently, wherein the catch 124 of one fastener 122 is disposed downward and the catch 124 of the other fastener 122 is disposed upward. The connection section 142 of the conductive connector 140 is fixed in the buckling part 121, specifically, the connection section 142 is buckled by the buckles 124 of the two buckling parts 122 from two different directions, so that the connection section 142 is attached to the outer wall of the protruding part 120.

In addition, the extension section 146 of the conductive connecting member 140 is located below the protruding portion 120 and is attached to the lower surface of the protruding portion 120, the protruding portion 120 has a protective effect on the extension section 146, and other components of the ink jet printing apparatus can be prevented from scratching the extension section 146 during the installation of the ink cartridge 100.

Referring to fig. 11, a chip mounting surface 116 is provided on the front wall 111 of the case 110, and the chip mounting surface 116 is located below the boss 120. Since only four communication terminals 132 are disposed on the first surface of the ink cartridge chip 130, the four communication terminals 132 and the ground terminal 136 on the second surface are all located on the left side of the center line L1 of the ink outlet 17, the area of the ink cartridge chip 130 can be made small, so that the area of the ink cartridge chip 130 is smaller than the area of the chip mounting surface 116, and thus the production cost of the ink cartridge chip 130 can be reduced.

Since the present invention provides the ground terminal 136 on the second surface of the cartridge chip 130, the ground terminal 136 is not visible on the outer surface of the cartridge 100 when the cartridge chip 130 is mounted to the case 110. In this way, even if ink drops onto the substrate 131, the ink drops only onto the communication terminal 132 and does not easily drop onto the ground terminal 136, so that the ground terminal 136 is not easily contacted with ink, the ground level received by the memory is ensured not to be divided, damage caused by the fact that the memory receives a negative voltage signal can be effectively avoided, the problem that the memory erroneously recognizes a signal sent by the inkjet printing device due to too low voltage of a clock signal, a data signal and the like is avoided, and meanwhile, the ground terminal 136 on the second surface of the ink cartridge chip 130 is directly contacted with the ground contact of the contact pin 161 on the first side of the contact pin frame 160 through the conductive connecting piece 140 and is not contacted with the ground contact pin of the contact pin 161 on the first side of the contact pin frame 160, and damage to the memory is not caused even if the ink drops onto the ground contact pin of the contact pin 161 on the first side of the contact pin frame 160. Because of the shielding effect of the stylus holder 160, the ink is hard to fall onto the ground contact of the rear main control circuit board 150 through the stylus holder 160, so that the problem caused by overlarge ground resistance of the memory of the ink cartridge chip 130 can be greatly reduced.

In this embodiment, the elastic portion 145 of the conductive connecting member 140 contacts the ground terminal 136 on the back surface of the substrate 131, so that the elastic portion 145 of the conductive connecting member 140 needs to be pressed downward a distance against the elastic force of the conductive connecting member 140 when the ink cartridge chip 130 is mounted to the ink cartridge 100 in order to ensure the contact stability between the elastic portion 145 of the conductive connecting member 140 and the ground terminal 136. However, the cartridge chip 130 is pushed up by the elastic force of the elastic portion 145, and if the thermal welding strength of the stopper 138 is insufficient, the cartridge chip 130 is at risk of falling off from the cartridge 100.

Second embodiment:

the ink jet printing apparatus of this embodiment is provided with a body in which a carriage is formed, and ink cartridges are detachably mounted in the carriage, and referring to fig. 16 and 17, each ink cartridge 200 has a cartridge body 210, the cartridge body 210 encloses a chamber for containing ink, and an ink outlet communicating with the chamber is provided below the chamber. A handle 212 is provided at the upper end of the case 210, and preferably, the handle 212 is an elastic handle that can be pressed and elastically deformed. Further, an ink cartridge chip 230 is detachably mounted on one front wall of the lower end of the cartridge body 210.

The cartridge chip 230 has a substrate 231, four communication terminals 232 are provided on a first surface of the substrate 231, and unlike the first embodiment, a ground terminal 236 of the present embodiment is also provided on the first surface of the substrate 231, see fig. 17 and 18. The four communication terminals 232 and the ground terminal 236 are located on the same side of the ink outlet center line L2.

In addition, the ink cartridge 200 is further provided with a conductive connecting member 240, wherein the conductive connecting member 240 is made of metal and comprises a first abutting section 241, a connecting section 242 and a second abutting section 243, and the connecting section 242 is located between the first abutting section 241 and the second abutting section 243. The lower end of the first abutting section 241 is a free end, an elastic portion 245 is provided on the free end, the elastic portion 245 is a first end of the conductive connector 240, the elastic portion 245 abuts against the grounding terminal 236, and the elastic portion 245 is curved. By providing the conductive connection 240, the ground terminal 236 does not make electrical contact with any contact pin on the side of the carriage facing the substrate 231 when the cartridge is mounted to or removed from the inkjet printing apparatus.

A boss 220 is provided on the front wall of the ink cartridge 200, the boss 220 being located below the handle 212. The boss 220 is provided with a fastening part 221, and the fastening part 221 includes two fasteners for fastening the connection section 242, so that the connection section 242 is attached to the outer wall of the boss 220.

When the conductive connector 240 is mounted to the ink cartridge 200, the first abutting section 241 is inserted into a side of the substrate 231 near the front wall of the ink cartridge 200, the second abutting section 243 is located on the second side of the stylus holder, and the connecting section 242 is located above the stylus supporting portion of the stylus holder.

Since the ink outlet of the ink cartridge is completely sealed by the film before the ink cartridge is mounted in the ink jet printing apparatus, so as to prevent leakage of ink during production and transportation, the ink dripping to the ink cartridge chip 230 mainly occurs after the ink cartridge 200 is mounted in the ink jet printing apparatus, and in this embodiment, the conductive connecting member 240 is already fixed to the cartridge body 210 before the ink cartridge 200 is mounted to the printing carriage, that is, the conductive connecting member 240 is fixed by the fastening portion 221, and at this time, the elastic portion 245 of the conductive connecting member 240 is already in close contact with the ground terminal 236. In this way, even if ink drops onto the elastic portion 245 of the conductive connector 240 and the ground terminal 236, since the elastic portion 245 of the conductive connector 240 is already in close contact with the ground terminal 236, a large resistance is not formed between the elastic portion 245 of the conductive connector 240 and the ground terminal 236 due to the presence of ink, and partial pressure to other connection terminals is not caused.

In contrast to the first embodiment, the elastic portion 245 of the conductive connector 240 of the present embodiment abuts on the first surface of the substrate 231, so that the ink cartridge chip 230 can be prevented from falling off.

In addition, the ink cartridge 300 is further provided with a conductive connecting member 340, wherein the conductive connecting member 340 is made of metal and comprises a first abutting section 341, a connecting section 342 and a second abutting section 343, and the connecting section 342 is located between the first abutting section 341 and the second abutting section 343.

By providing the conductive connection 340, the ground terminal 336 does not make electrical contact with any contact pin on the side of the carriage facing the substrate 331 when the ink cartridge is mounted to or removed from the inkjet printing apparatus.

Since the ink dripping to the ink cartridge chip 330 mainly occurs after the ink cartridge 300 is mounted to the ink jet printing apparatus, in the present embodiment, the conductive connecting member 340 is already fixed to the cartridge body 310 before the ink cartridge 300 is mounted to the printing carriage, that is, the conductive connecting member 340 is fixed by the fastening portion 321, and at this time, the elastic portion 345 of the conductive connecting member 340 is already in close contact with the ground terminal 336. In this way, even if ink drops onto the elastic portion 345 of the conductive connector 340 and the ground terminal 336, since the elastic portion 345 of the conductive connector 340 is already in close contact with the ground terminal 336, a large resistance is not formed between the elastic portion 345 of the conductive connector 340 and the ground terminal 336 due to the presence of ink, and partial pressure to other connection terminals is not caused.

In contrast to the first embodiment, the elastic portion 345 of the conductive connector 340 of the present embodiment abuts on the top of the substrate 331, so that the ink cartridge chip 330 can be prevented from falling off the cartridge body 310.

In this embodiment, the front surface of the substrate faces the stylus holder 460, and the back surface faces away from the stylus holder 460, for example, a plurality of connection terminals 432 are disposed on the front surface of the substrate. The arrangement of the connection terminals on the back surface of the substrate can be changed according to actual requirements, for example, the connection terminals can be sequentially arranged into a straight line or can be separately arranged into a circle around the main controller; the connection terminals located on the back surface of the substrate may be disposed on the side surface of the substrate, or may be disposed on an edge where the side surface of the substrate intersects the back surface, and the arrangement and combination manner of the connection terminals on the substrate are not limited in this embodiment.

It can be seen that there are two electrically connected paths between the connection terminals on the cartridge chip 430 and the contacts of the main control circuit board 450, one path being the contact pins 462 on the contact pin supporting portion 461 and the other path being the conductive connection member 420, so that in the case that the contact pins 462 of the contact pin supporting portion 461 are damaged, the connection terminals of the cartridge chip 430 can be electrically connected with the contacts of the main control circuit board 450 through the conductive connection member 420. Of course, in other embodiments, the connection terminals on the front side of the substrate of the cartridge chip 430 may be omitted, and the connection terminals on the back side of the substrate of the cartridge chip 430 and the conductive connection member 420 are electrically connected to the main control circuit board 450, so that the short circuit caused by the ink falling between the connection terminals on the front side of the substrate may be avoided.

A fixing block 470 is disposed on the outer side of the outer wall of the case 410 near the stylus holder 460, the fixing block 470 is disposed above the ink cartridge chip 430, and as can be seen from fig. 26, two fastening members 471 are disposed on the fixing block 470. Two fastening positions 421 are provided on the outer wall of the case 410, and each fastening member 471 is fastened to one fastening position 421, so as to realize the fixed connection between the fixing block 470 and the ink cartridge 400 in the up-down, left-right directions.

A portion of the conductive connector 420 is clamped between the fixing block 470 and the outer wall of the case 410, so that the conductive connector 420 can be fixed to the ink cartridge 400. In addition, a plurality of mounting grooves 426 are formed on the outer wall of the case 410, and a section of one conductive connector 420 can be fixed in one mounting groove 426, so that the conductive connector 420 is prevented from being displaced relative to the fixing block 470, and the mounting groove 426 is also beneficial to avoiding damage of the conductive connector 420.

When the ink cartridge 400 is assembled, a plurality of conductive connectors 420 are first placed on the outer wall of the ink cartridge 400, for example, the conductive connectors 420 are mounted on corresponding mounting grooves 426, then the fixing blocks 470 are placed on the cartridge body 410, and the fixing blocks 470 are buckled on the outer wall of the cartridge body 410, so that the fixing blocks 470 limit the conductive connectors 420. Finally, the cartridge chip 430 is mounted to the outer wall of the case 410.

When the ink cartridge 400 is mounted to the ink jet printing apparatus, the second end 422 of the conductive connector 420 is automatically inserted between the stylus holder 450 and the main control circuit board 460 with the insertion of the ink cartridge, so that the second end 422 of the conductive connector 420 is electrically connected to corresponding contacts on the main control circuit board 460. In this way, the connection terminals of the cartridge chip 430 may be directly electrically connected to corresponding contacts on the main control circuit board 460 through the conductive connection member 420.
