As shown in fig. 7, the cartridge body 30 of the consumable cartridge is provided with a front end wall 301 on the front side in the mounting direction of the consumable cartridge, and the walls intersecting the front end wall 301 have a top wall 303, a bottom wall 304, a left side wall 305 and a right side wall 306, and a rear end wall 302 opposite to the front end wall 301. It should be noted that the cartridge 30 of the embodiment of the present invention is the same as the cartridge in the prior art.

As shown in fig. 7 and 8, the chip mounting structure 20 of the consumable cartridge is disposed on the front end wall 301 of the cartridge body 30, and the chip mounting structure 20 is substantially in the shape of a rectangular parallelepiped. The chip mounting structure 20 may be fixed to the front end wall 301 of the case 30 by soldering, bonding, or the like.

The surface of the chip mounting structure 20 in contact with the case 30 is a rear end surface 202, the surface opposite to the rear end surface 202 is a front end surface 201, and the surfaces intersecting the front end surface 201 are a left side surface 203, a right side surface 204, a bottom surface 205, and a top surface 206, respectively. The left side 203 and the right side 204 are collectively referred to as sides.

As shown in fig. 7 and 9, the connection portion 11 is fixed on the front end surface 201 of the chip mounting structure 20 of the consumable cartridge, the bent portion 12 is fixed on the side surface of the chip mounting structure 20, and the bent portion 12 extends along the chip mounting direction. When the consumable chip 1 is in contact with the contact element, the second terminal 124 on the bending part 12 is clamped by the two contact pins 401 which are farthest away from the contact element, and due to the interaction force between the two contact pins which are farthest away from the contact element and the second terminal 124, the contact of the second terminal 124 and the contact pins 401 is stable, the consumable box is not easy to displace, and therefore the contact point of the consumable chip and the contact pins of the contact element can form stable electric connection.

Specifically, the connection portion 11 may be fixed on the front end surface 201 of the chip mounting structure 20 by means of adhesion, soldering, or the like. The bent portion 12 may be fixed on the side surface of the chip mounting structure 20 by means of adhesion, soldering, or the like.

Since the front end surface 201 and the side surface of the chip mounting structure 20 are not in the same plane, the first terminal 111 on the connection portion 11 and the second terminal 124 on the bent portion 12 are not in the same plane.

When the consumable chip 1 is mounted, the connection portion 11 is fixed to the front end surface 201 of the chip mounting structure 20, the bent portion 12 on the left side of the connection portion 11 is bent toward the left side surface 203 of the chip mounting structure 20 and fixed to the left side surface 203, and the bent portion 12 on the right side of the connection portion 11 is bent toward the right side surface 204 of the chip mounting structure 20 and fixed to the right side surface 204.

When the consumable chip 1 is contacted with the contact element, the contact pin in the middle position on the contact element is electrically connected with the contact point of the first contact part through point contact, the two contact pins farthest away on the contact element are electrically connected with the contact point of the second contact part through surface contact, the two contact pins farthest away clamp the second terminal 124, because the first terminal 111 and the second terminal 124 are not in the same plane and the interaction force between the second terminal 124 and the two contact pins farthest away on the contact element, the box body 30 and the chip mounting structure 20 are limited between the two contact pins farthest away, the box body 30 and the chip mounting structure 20 are not easy to displace, so that the consumable box is not easy to displace, and further the contact point of the consumable chip and the contact pin of the contact element can form stable electrical connection.

The two contact pins that are farthest from each other on the contact are the two contact pins that are farthest from each other in the left-right direction of the case 30 when the consumable chip 1 is in contact with the contact.

In order to ensure that the two farthest contact pins can hold the second terminals 124, the length of the connecting portion 11 in the left-right direction of the box body 30 is smaller than or equal to the distance between the two farthest contact pins.

The flexible circuit board 10 is further provided with a circuit module, and the circuit module includes one or more components of a controller, a memory, a capacitor, an electric energy storage device, and the like. The memory is used for storing consumable box related information, including consumable capacity information (consumption or residual amount), consumable box manufacturer information, production date, serial number and the like. The electrical energy storage device can be used to provide the memory with the voltage required for its operation when needed to maintain the operation of the memory.

Since the second terminal 124 operates at a higher voltage than the first terminal 111, when the consumable chip 1 is mounted on the chip mounting structure 20 of the consumable cartridge, the second terminal 124 and the first terminal 111 are in different planes, which can prevent a short circuit from occurring between the second terminal 124 and the first terminal 111, thereby protecting the terminals of the consumable chip that operate at a lower voltage and preventing the memory from being damaged.

Alternatively, as shown in fig. 6, the second terminal 124 is a protrusion in a direction perpendicular to the bent portion 12. The protrusion may be formed in a convex manner by copper-clad.

The second terminals 124 may be elastic protrusions or protrusions without elasticity.

In an alternative embodiment, the second terminal 124 is a protrusion formed in a convex manner by copper plating, leaving some clearance from the left side 203 of the chip mounting structure 20. When the protrusion is in contact with the contact pin 401 of the contact of the printing apparatus, the protrusion can be compressed for a certain distance and deformed after being pressed by contact due to a certain hardness, and the deformation is recovered after the force is removed, so that the protrusion has a certain elasticity and is therefore an elastic protrusion. With the arrangement, after the consumable chip 1 is mounted on the box body 30, the second terminal 124 is elastically deformed after being contacted with the contact pin 401 of the contact element, so that the contact stability can be ensured, and the problem that the contact pin 401 of the contact element is easily damaged when the consumable box is mounted on a printing device can be solved.

Further, the second terminals 124 are circular arc-shaped elastic protrusions. So set up, when this convex elastic bulge contacts with the contact pilotage 401 of printing apparatus's contact, this convex elastic bulge can take place deformation by the compression certain distance, and this deformation makes bellied circular arc end extruded and forms a plane, compares in the point contact that contact pilotage and plane go on, the utility model discloses the contact pilotage of printing apparatus's contact has formed surface contact with second terminal 124, has increased area of contact, has consequently formed more stable electricity and has connected.

Alternatively, the side surface of the chip mounting structure 20 is provided with a positioning post (not shown), and the bent portion 12 is provided with a positioning hole (not shown), into which the positioning post can be inserted. With this arrangement, the bent portion 12 can be positioned on the side surface of the chip mounting structure, so that the second terminal 124 can be brought into stable electrical connection with the contact pin 401 of the contact.

The side surface of the chip mounting structure 20 includes a left side surface 203 and a right side surface 204, and positioning columns are disposed on the left side surface 203 and the right side surface 204.

Fig. 10 is a schematic structural diagram of a chip mounting structure of another consumable cartridge according to an embodiment of the present invention; FIG. 11 is a schematic structural diagram of a consumable chip of the consumable cartridge of FIG. 10.

The first end 121 of the bending portion 12 may be fixed on the side surface of the chip mounting structure 20 by means of adhesion, welding, or the like.

The connecting portion 11 is provided with bent portions 12 at both ends thereof. The chip mounting direction is a direction in which the front end wall 301 of the case 30 is directed toward the rear end wall 302.

Alternatively, as shown in fig. 10, a support member 40 is disposed between the hanging portion 123 and the side surface of the chip mounting structure 20, and the support member 40 supports the second terminal 124 on the bending portion 12, so that the second terminal 124 is arched by the support member 40. With this arrangement, stable contact between the second terminals 124 and the contact pins of the contact can be achieved. Note that, in this example, the second terminal 124 is not formed with a protrusion on the bent portion 12.

The supporting member 40 may or may not have elasticity, and is not specifically provided herein.

In an alternative embodiment, the support 40 is a resilient support, such as a spring. With the arrangement, after the consumable chip is mounted on the chip mounting structure 20, the second terminal 124 is elastically deformed after being contacted with the contact pin of the contact element through the support piece 40, so that the contact stability can be ensured, and the problem that the contact pin of the contact element is easily damaged when the consumable box is mounted on the printing equipment can be solved.

Further, the support 40 is a circular arc-shaped solder. Specifically, the support 40 is an arc-shaped protrusion formed on the side surface of the chip mounting structure 20 in a protruding manner by solder, a gap is left between the top end of the arc-shaped protrusion and the side surface of the chip mounting structure 20, when the arc-shaped protrusion abuts against the contact pin of the contact of the printing apparatus, the arc-shaped protrusion can be compressed for a certain distance to deform after being pressed against the contact pin, and after the acting force is removed, the deformation is recovered, so that the arc-shaped protrusion has a certain elasticity, and thus, the arc-shaped solder is an elastic support.

When the second terminal 124 is arched by the supporting member 40, the second terminal 124 contacts with the contact pin of the contact element of the printing apparatus, the supporting member 40 can be compressed for a certain distance to generate elastic deformation, the elastic deformation enables the protruding arc end formed by the supporting member 40 to be pressed to form a plane, compared with the point contact of the contact pin and the plane in the prior art, the contact pin of the contact element of the printing apparatus of the embodiment of the invention forms surface contact with the second terminal 124, thereby forming more stable electric connection.
