The third contact portion 2061 may be provided at an end portion closer to the surface 203, and the second contact portion 2061 is closer to the contact needle 4. With such a structure, better contact between the tip 1 and the contact needle 4 can be further guaranteed, and the stability and reliability of use of the tip 1 are improved.

Further combined with FIGS. 5a-5b, the present embodiment provides another type of chip 1. The chip 1 is electrically connected to the contact needle 4 in the printer holding portion, and the contact needle 4 has different heights and is arranged in a staggered pattern with the first group of contact needles 401 and the second group of contact needles.

A plurality of grooves 205 are provided, the second through groove 205 penetrates the first surface 201 and the second surface 202, and a part of at least one second through groove 205 is at least a part of the first contact portion 1061. Covered by.

However, since the chip structure in this embodiment is the same as the chip structure corresponding to FIGS. 3a1 to 3c2 and 4a to 4b, the above description may be referred to for details. It will not be explained repeatedly here.

Further, as can be seen with reference to FIGS. 5a to 5b regarding the structure of the contact needle 4, the contact needles 4 are arranged in a staggered manner in a direction perpendicular to the Z-axis direction, and the contact needles 401 of the first group and the first group. Two groups of contact needles 402 may be provided, and the contact needles 401 of the first group and the contact needles 402 of the second group are located at different heights in the Z-axis direction. Further, the contact needle 401 of the first group and the contact needle 402 of the second group are the rod portion 404, the horizontal portion 403 located at the upper end of the rod portion 404, and the head portion located at the lower end of the rod portion 404. 405 may be provided, the head portion 405 and the lateral portion 403 are connected via the rod portion 404, and the head portion 405 and the rod portion 404 are rotatable around the lateral portion 403. At that time, the contact needle 4 has elasticity to some extent, and when pressure is applied to the head portion 405 or the rod portion 404 of the contact needle 4, the contact needle 4 makes a corresponding rotation.

As can be seen with reference to FIGS. 6a to 6c, when the tip 1 comes into contact with the contact needle 4, the first contact portion 1061 comes into contact with the contact needle 401 of the first group, and the second contact portion 2061 In contact with the contact needle 402 of the second group, the first through groove 105 accommodates the contact needle 402 of the second group, and the second through groove 205 accommodates the contact needle 401 of the first group.

However, when the first chip portion 100 and the second chip portion 200 are installed, the first substrate 104 and the second substrate 204 may be made of the same material or may be made of different materials. Specifically, as one type of feasible method, the first chip portion 100 may be a hard plate, or the hard plate portion may be made of FR-4 material. The hard plate portion does not deform even when a force is applied, has a fixed shape and size, and does not deform. The second chip portion 200 may be a soft plate chip, and the soft plate portion may use a flexible circuit board FPC material, has a flexible feature, and is easily curved or deformed. At that time, when the second contact portion 2061 comes into contact with the contact needle 402 of the second group, the second contact portion 2061 can be deformed by the action of the contact force applied from the contact needle 4 to the second tip portion 200. is there. Specifically, as shown in FIGS. 7a to 7a1, the second chip portion 200 may be a soft plate chip, and the second chip portion 200 is a chip from a direction perpendicular to the third surface 203 of the second chip portion 200. When observing No. 1, the deformed second contact portion 2061 and the first contact portion 1061 are arranged side by side in a row, or after the second contact portion 2061 is deformed, the second terminal 206 and the first contact portion 2061 are arranged side by side. The terminals 106 are arranged side by side in a row.

Specifically, after the tip 1 is joined to the contact needle 4, the contact needle 402 of the second group is joined to the second tip portion 200. Since the contact needle 4 generates an acting force on the second contact portion 2061 in the second tip portion 200, a part of the second contact portion 2061 is deformed downward (T direction) to some extent. In this way, the second terminal 206 is also deformed downward (T direction) to some extent. As shown in FIGS. 7a to 7a1, in the mounting direction T, the position after the tip 1 comes into contact with the contact needle 4 and the second terminal 206 is deformed and the first terminal 106 exhibit a one-row arrangement. That is, both the second terminal 206 and the first terminal 106 are provided side by side with L1. The position after the second contact portion 2061 is deformed and the first contact portion 1061 exhibit a one-row arrangement. That is, the second contact portion 2061 and the first contact portion 1061 are both provided side by side on the horizontal straight line L1. At that time, the second contact portion 2061 may be provided directly below the first through groove 105 (in the direction of the −Z axis).

As can be seen by continuing to refer to FIGS. 7b to 7b1 based on the above embodiment, the difference from the embodiment corresponding to FIGS. 7a to 7a1 is that the second chip portion 200 in this embodiment is a hard plate chip. Yes, the material may be FR-4 material, and in the normal case, the hard plate tip does not deform as a default. At that time, when the first chip portion 100 is connected to the second chip portion 200, when the chip 1 is observed from the direction perpendicular to the third surface 203 of the second chip portion 200, the second contact portion after deformation is observed. The 2061 and the first contact portion 1061 are provided so as to exhibit a two-row arrangement. That is, the first contact portions 1061 are provided side by side on the horizontal straight line L2, and the second contact portions 2061 are provided side by side on the horizontal straight line L3. Alternatively, the second terminal 206 and the first terminal 106 are provided so as to exhibit a two-row arrangement. That is, the first terminal 106 is provided side by side on the horizontal straight line L2, and the second terminal 206 is provided side by side on the horizontal straight line L3.

Specifically, when the second surface 102 of the first chip portion 100 comes into contact with the second surface 202 of the second chip portion 200, the first terminals 106 and the second terminals 106 and the second provided on the first substrate 104 and the second substrate 204, respectively. Since the terminal 206 may be formed by plating the substrate with copper, the position of the second terminal 206 and the position of the first terminal 106 are set after the chip 1 comes into contact with the contact needle 4 in the mounting direction T. Shows a two-row arrangement, and the position of the second contact portion 2061 and the first contact portion 1061 exhibit a two-row arrangement. Further, the second contact portion 2061 may be provided inside the first through groove 105.

As can be seen by continuing to refer to FIGS. 7c to 7c1 based on the above embodiment, the difference between the examples corresponding to FIGS. 7a to 7a1 and 7b to 7b1 is that the first chip portion 100 in this embodiment is used. And the second chip portion 200 are connected via the intermediate portion 5. However, the intermediate portion 5 may have a connection structure provided independently, or may be provided in the first chip portion 100 or the second chip portion 200. After the first chip portion 100 and the second chip portion 200 are connected via the intermediate portion 5, a gap is formed between the first chip portion 100 and the second chip portion 200. A first terminal 106 and a second terminal 206 are provided in the gap. At that time, with respect to the intermediate portion 5, the intermediate portion 5 is provided between the first chip portion 100 and the second chip portion 200, and the first chip portion 100 intersects the first surface 101 and the second surface 102. When the chip 1 is further provided with the three surfaces 103 and the chip 1 is observed from the direction perpendicular to the third surface 103 of the first chip portion 100, the height of the intermediate portion 5 is the copper plating thickness of the first terminal 106 and the copper plating thickness of the second terminal 206. It is the sum of the copper plating thickness. Further, when the chip 1 is observed from the direction perpendicular to the third surface 103 of the first chip portion 100, the intermediate portion 5, the first terminal 106 and the second terminal 206 exhibit a one-row arrangement. That is, the intermediate portion 5, the first terminal 106 and the second terminal 206 exhibit a one-row arrangement in the horizontal straight line L4. Alternatively, the first contact portion 1061 and the second contact portion 2061 exhibit a one-row arrangement. That is, the first contact portion 1061 and the second contact portion 2061 exhibit a one-row arrangement in the horizontal straight line L4.

Specifically, the first surface 101 of the first chip portion 100 is provided so as to face the second surface 202 of the second chip portion 200, and an intermediate portion is provided between the first chip portion 100 and the second chip portion 200. The length of the intermediate portion 5 in the direction T is the sum of the copper plating thicknesses of the first terminal 106 and the second terminal 206. Therefore, due to the presence of the intermediate portion 5, the intermediate portion 5, the first terminal 106 and the second terminal 206 may exhibit a one-row arrangement. Since the first contact portion 1061 is at least a part of the first terminal 106 and the second contact portion 2061 is at least a part of the second terminal 206, the first contact portion 1061 and the second contact portion 2061 are in the direction T. Also, a one-row array may be exhibited. Further, the second contact portion 2061 is provided directly below the first through groove 105 (in the direction of the −Z axis). With such a structure, since the intermediate portion 5 is provided between the first chip portion 100 and the second chip portion 200, the first chip portion 100 and the second chip portion 200 do not come into direct contact with each other. In this structure, it is possible to avoid damage to the chip due to the unevenness between the first surface 201 of the first chip portion 100 and the second surface 202 of the second chip portion 200, and the rigid contact between the two. ..

The first chip portion 100 and the second chip portion 200 in this embodiment may be in contact with each other, or may be connected via an intermediate portion 5. Further, the first chip portion 100 and the second chip portion 200 may be made of the same material or different materials. The feasible form of the structure of the chip 1 is effectively expanded, the structure of the chip 1 becomes flexible and diverse, and it becomes convenient for the user to install the corresponding structure of the chip 1 according to the specific design demand. , The applicable range of the chip 1 is further expanded.

Based on the above embodiment, as can be seen by continuing to refer to FIGS. 10a to 10b, the first chip portion 100 and the second chip portion 200 may be combined and connected by another method. Specifically, the second chip portion 200 may include a joint portion 6. The second terminal 206 is connected to one side end of the joint portion 6, and the second chip portion 200 is connected to the first chip portion 100 via the joint portion 6.

However, the joining portion 6 may be a joining mechanism provided between the first chip portion 100 and the second chip portion 200, or may be a joining mechanism provided between the second terminals 206. However, the second terminal 206 may be a copper piece. The second terminal 206 may communicate with the first chip portion 100 via the joint portion 6. As shown in FIGS. 10a to 10b, since the second terminal 206 is suspended on the joint portion 6, the second terminal 206 has a constant moving space with respect to the joint portion 6. Since the second contact portion 2061 is at least a part of the second terminal 206, the second contact portion 2061 also has a constant moving space with respect to the joint portion 6. Therefore, when the tip 1 comes into contact with the contact needle 4, the contact needle 402 of the second group gives a contact force to the second tip portion 201 to some extent, and the second tip portion 200 moves by the action of the contact force. Specifically, the second chip portion 200 is movable with respect to the first chip portion 100. Further, when the chip 1 is observed from the direction perpendicular to the third surface 203 of the second chip portion 200, the second contact portion 2061 and the first contact portion 1061 after the movement may exhibit a one-row arrangement. Alternatively, after the second contact portion 2061 has moved, the second terminal 206 and the first terminal 106 may exhibit a one-row arrangement.

Specifically, FIG. 11 shows a schematic diagram in which the tip 1 comes into contact with the contact needle 4. When the contact needle 402 of the second group is joined to the second terminal 206, the second terminal 206 moves in the −T direction / −Z axis direction by the acting force of the contact needle 402 of the second group, and the second terminal 206 The two contact portions 2061 also move in the −T direction / −Z axis direction due to the acting force of the contact needle 402 of the second group. Thereby, the effect that the first contact portion 1061 exhibits a single row arrangement in the direction T can be achieved.

Since the second chip portion 200 in this embodiment is connected to the first chip portion 100 via the joint portion 6, the stable reliability of the connection between the first chip portion 100 and the second chip portion 200 is guaranteed, while the stability and reliability of the connection are guaranteed. The connection method between the first chip portion 100 and the second chip portion 200 is also expanded, and the processing and manufacturing of the chip 1 becomes convenient.

As can be seen by continuing to refer to FIG. 12 based on the above embodiment, the difference from the embodiment corresponding to the above FIGS. 10a to 10b is that the first chip portion 100 and the second chip portion 200 in this embodiment are different. Is movably connected via the joint portion 6. Preferably, the first chip portion 100 and the second chip portion 200 are hinged to each other via the joint portion 6. After the first chip portion 100 is connected to the second chip portion 200, the second chip portion 200 can move (including a moving method such as rotation, rotation, movement, etc.) with respect to the first chip portion 100. At that time, for the first chip portion 100 and the second chip portion 200, the first chip portion 100 cannot move or rotate with respect to the second chip portion 200, and the second chip portion 200 becomes the first chip portion 100. On the other hand, it can rotate and move. For example, by adjusting the angle formed between the second chip portion 200 and the first chip portion 100, the first chip portion 100 becomes perpendicular, intersecting, or parallel to the second chip portion 200. When the first chip portion 100 is parallel to the second chip portion 200, the plurality of contact portions 109 provided on the first chip portion 100 come into contact with the plurality of contacted portions 209 provided on the second chip portion 200. To do.

Another feasible method is as follows. As shown in FIGS. 13a to 13c, the first chip portion 100 and the second chip portion 200 are movably connected via the connecting portion 7, and preferably the first chip portion 100 and the second chip portion 200 are connected. It is hinged via the portion 7, and one end of the connecting portion 7 is connected to the end of the first chip portion 100, and the other end is connected to the end of the second chip portion 200. After the first chip portion 100 is connected to the second chip portion 200, the first chip portion 100 and the second chip portion 200 move relative to each other (rotation, rotation, movement, etc.) so that the first chip portion 100 can be further implemented. (Including) is possible. At that time, for the first chip portion 100 and the second chip portion 200, the first chip portion 100 is movable and rotatable with respect to the second chip portion 200, and the second chip portion 200 is also the first chip portion 100. Can rotate and move with respect to. The chip 1 is configured by combining the first chip portion 100, the second chip portion 200, and the connecting portion 7. As can be understood, the connecting portion 7 has a flexible feature and is easily curved or deformed. For example, the connection portion 7 is manufactured of a flexible circuit board FPC material. Further, the connecting portion 7 may be provided with a folding line, and the first chip portion 100 and the second chip portion 200 are folded as the chip 1 via the connecting portion 7. At that time, the chip 1 may be produced by a folding method. That is, the chip 1 is formed by folding the first chip portion 100 and the second chip portion 200 by the folding line provided in the connecting portion 7. However, the production process of this method is complicated, and a folding line is provided at the folding portion at the connecting portion 7. In this method, when the chip 1 is folded, the folding trace may deviate from a predetermined folding line, resulting in a misalignment between the terminals. In addition, the chip line may be disconnected by the folding method. Therefore, preferably, the chip 1 is produced in a non-folding manner. By adopting the chip 1 produced by the non-folding method and the production method of welding or positioning buckle and positioning hole or positioning column and positioning hole or sticking with adhesive, misalignment between terminals is less likely to occur. , Chip line disconnection does not occur.

At the time of specific application, as can be seen with reference to FIGS. 14a to 14b, the tip 1 in this embodiment may come into contact with the contact needle 4. Specifically, the chip 1 may be attached to the chip rack. However, the structure of the chip rack may be the one shown in FIG. 15, and the chip rack is attached to the ink cartridge. In this way, the tip 1 and the contact needle 4 realize an electrical connection. However, the second chip portion 200 is movable with respect to the first chip portion 100. Rather than a connection structure in which the first chip portion 100 is immovable with respect to the second chip portion 200, the chip rack also rotates with the chip 1 after the chip 1 is attached to the chip rack. Not only does it occupy space, but the structure is also complicated for ink cartridges that need to be fitted with chip racks. Therefore, in this embodiment, by making the second chip portion 200 and the first chip portion 100 a relatively movable structure, attachment / detachment between the chip 1 and the chip rack becomes convenient, and the chip 1 The whole rotation is unnecessary. Therefore, the structure is simple, the space occupied is small, and the ink cartridge and the printer can be easily miniaturized.

Based on the above embodiment, as can be seen by continuing to refer to FIG. 4a, the tip 1 in this embodiment is further provided with a third terminal 3 that does not come into contact with the contact needle 4. However, the third terminal 3 is provided in the first chip portion 100, or the third terminal 3 is provided in the second chip portion 200, or the third terminal 3 is provided in the first chip portion 100 and the second chip portion 100. It is provided on the chip portion 200.

Specifically, the third terminal 3 is used to detect whether or not there is a short circuit between the first terminal 106, the second terminal 206, or the first terminal 106 and the second terminal 206. May be done. The third terminal 3 may be used to detect whether or not water marks, black marks, or polka dots are present on the surface of the chip 1. The third terminal 3 may be used to detect something else. As shown in FIG. 4a, when the third terminal 3 is located on the first chip portion 100, the installation position of the third terminal 3 and the installation position of the first terminal 106 are the same. The details will not be repeated here because the above description may be referred to. When the third terminal 3 is located at the second chip portion 200, the installation position of the third terminal 3 and the installation position of the second terminal 206 are the same. The details will not be repeated here because the above description may be referred to. The installed third terminal 3 can more effectively detect the connection state between the first chip portion 100 and the first terminal 106 and the second terminal 206 in the second chip portion 200, and stabilize the use of the chip 1. The reliability is further improved.

The installed third through groove 108 effectively protects the first contact portion 1061 and prevents the first contact portion 1061 from being easily damaged. Further, when the tip 1 comes into contact with the contact needle 4, it is possible to perform a guiding action on the contact needle 4, the contact effect between the tip 1 and the contact portion is ensured, and the stability and reliability of using the tip 1 are ensured. Is further improved.
