The ink cartridge is a consumable in the ink jet printer, and when the ink cartridge in the ink jet printer is used up, the ink cartridge needs to be replaced by a new ink cartridge and mounted on a mounting portion of the printing apparatus. The ink box is generally provided with a chip, and a contact pin part on the printer installation part is contacted with a terminal on the ink box chip to form electric connection so as to complete the work of electric signal transmission and storage between the ink box and the printer.

Fig. 1 is a schematic diagram of prior art contact of a chip and contact pin sets of a contact pin portion. The chip comprises a first substrate 1 'and a second substrate 2'. The first substrate 1 'and the second substrate 2' are arranged in a staggered manner, and terminals are respectively arranged on the 2 substrates. The first substrate 1' comprises 4 first terminals 11' to 14 '. The second substrate 2' includes 5 second terminals 21' to 25 '. The 9 terminals on the chip are in contact with the contact pins 55' of the contact pin part to form electrical connection, and the electrical signal transmission and storage between the ink box and the printer are completed. The number of contact pins 55' corresponds to the number of terminals, and there are 9 contact pins, corresponding to 9 terminals one by one, and only 3 contact pins are shown in fig. 1 for better illustration of the contact manner.

In the prior art, among 9 terminals: the terminals 12', 13', 22', 23', 24' are connected to the dies of the chip, which are die terminals, which are given a lower voltage (e.g., 3.6V) by the printer to maintain the proper operation of the dies. Some of the second terminals 21', 25' are high voltage terminals to which a higher voltage (e.g., 42V) is applied by the printer to perform the mounting detection work. Some of the first terminals 11', 14' are short-circuit detection terminals for detecting a short-circuit condition between the terminals and preventing damage to the die due to a higher voltage applied to the die terminals. However, in the case where a part of the wafer terminals 22' to 24' is provided on the second substrate 2', particularly in the case of a part of the printer, the terminals 22' are provided as power supply terminals, and the short-circuit detection terminals 11' and 14' cannot effectively detect a short circuit between the terminals because the high-voltage terminals are too close to the wafer terminals 22' to 24' on the second substrate 2', which may easily cause a short circuit between the wafer terminals 22' to 24' on the second substrate 2', particularly between the power supply terminals 22' and the high-voltage terminals 21' and 25', and the short-circuit detection terminals 11' and 14' do not detect the occurrence of the short circuit, thereby causing a risk of damaging the chip or the printer.

For example, as ink in the ink cartridge is consumed, the ink volume information in the chip changes as the print volume changes.

Referring to fig. 4, the second substrate 2 has a substantially rectangular parallelepiped shape, and includes a first surface 201, a second surface 202, a third surface 203, a fourth surface 204, a fifth surface 205, and a sixth surface 206, the first surface 201 and the second surface 202 being arranged in parallel, the third surface 203 and the fourth surface 204 being arranged in parallel, and the fifth surface 205 and the sixth surface 206 being arranged in parallel.

The concave portion 22 is opened on the third surface 203 and penetrates the first surface 201 and the second surface 202, the first high voltage terminal 211 and the second high voltage terminal 212 are respectively arranged on the third surface 203 and extend to the first surface 201, the first high voltage terminal 211 and the second high voltage terminal 212 are located at two ends of the concave portion 22, specifically, the first high voltage terminal 211 is located on the-X axis side of the concave portion 22, and the second high voltage terminal 212 is located on the + X axis side of the concave portion 22. In the mounting direction of the chip 100 to the printing apparatus, the first high-voltage terminal 211 and the second high-voltage terminal 212 are disposed on the front end side of the first terminal 11, and at least a part of the recess 22 is located on the front end side of the first terminal 11. This application is through the design of this structure for the wafer terminal has been kept away from to the high voltage terminal, thereby makes the short circuit that the short circuit detection terminal can effectually detect between the terminal, has avoided the short circuit between especially power supply terminal of wafer terminal and the high voltage terminal, and then reduces the damaged risk of chip or printing apparatus.

Specifically, the second substrate 2 is further opened with a fourth hole 23, a fifth hole 24 and a sixth hole 25. Fourth and

fifth holes

23 and 24 penetrate the first and

second surfaces

201 and 202 for fixing the substrate to a chip carrier or an ink cartridge. The sixth hole 25 is a relief hole for avoiding a wafer or an electrical component provided on the first substrate 1. Of course, if necessary, a die or an electric component may be provided on the second substrate 2.

Further, the reset terminal 111, the clock terminal 112, the power supply terminal 113, the ground terminal 114, and the data terminal 115 may also be referred to as a die terminal for connecting with a die of the chip, the first high voltage terminal 211 and the second high voltage terminal 212 receive a higher voltage (e.g., 42V) than the die terminal, and the short detection terminal 116 is used for detecting whether a short occurs between the terminals of the chip.

Short-circuit detection terminal 116: for detecting whether a short circuit occurs between the terminals, and in particular, for detecting whether a short circuit occurs between the first and second

high voltage terminals

211 and 212 and the short detection terminal 116.
