The utility model is described in further detail below in conjunction with drawings and Examples.
The specific embodiment
Following examples introduce in process for concrete structure or parts, only understand referential illustration of the present utility model as those skilled in the art, those skilled in the art can also design or patterning obtains not exceeding the technical scope of the utility model or technical spirit various being equal to or similar technical characterictic under the enlightenment of embodiment description technique scheme.Thus, be unfavorable if limit with this exemplary illustration the protection domain that the utility model claim includes.Be equal to or be similar to the protection domain that the technical solution of the utility model still belongs to the utility model claim.
As shown in Figure 1, existing print cartridge 2 is dismountable to be arranged on the mounting portion 1 of printer, print cartridge 2 comprises the housing 21 that holds ink, the chip 22 that is used for the storage relevant information, for the elastic portion 23, latch 20 and the connecting portion 24 that print cartridge 2 are fixed on mounting portion 1, and the ink supply port 25 that is used for the supply ink; Wherein, housing 21 has roof 211, diapire 212 and sidewall 213 and sidewall 210.Chip 22 is arranged on the corner region between diapire 212 and sidewall 213.Printer mounting portion 1 comprises the ink channel 12 that docks with ink supply port 25, and the electric contact 11 that contacts with chip 22.
As shown in Figures 2 and 3, the print cartridge 3 of the utility model embodiment comprises housing 31, mainboard 32, elastic portion 33, latch 30 and connecting portion 34 and ink supply port 35; Wherein, housing 31 comprises roof 311, diapire 312, the first side wall 313, inwall 314 and the second sidewall 310, and the housing parts between the first side wall 313 and inwall 314 also is provided with for the locating part 315 that prevents that mainboard 32 from deviating from from housing 31.Connecting portion 34 is arranged on the first side wall 313, and mainboard 32 is arranged between the first side wall 313 and inwall 314.
As shown in Figure 4 and Figure 5, mainboard 32 comprises substrate 321, the dismountable chip 322 that is equipped with in the front side, top of substrate 321, the dismountable FPC 323 with conductive strips that is equipped with in the bottom of substrate 321.Conductive strips upper end on FPC 323 is connected with chip 322, the lower end of substrate 321 is walked around at the middle part of conductive strips, the lower end of substrate 321 is wrapped up fully, the other end of FPC 323 buckles on the buckle 327 of substrate 321 dorsal parts by fixing hole 326, thereby flexible cord wiring board 323 is fixed on substrate 321.The top of substrate 321 is provided with a pair of buckle 324 and pin 329, is used for fixed chip 322; The bottom of substrate 321 is provided with one group as the pressing plate 325 of pressing plate, makes FPC 323 be close to front side and the dorsal part of substrate 321.The top of substrate 321 is provided with elastic component 328, and elastic component 328 is the elastic sheet with substrate 321 integrated pair of curved.The sidepiece of substrate 321 is provided with a pair of recess 330.When mainboard 32 was arranged between the first side wall 313 and inwall 314, elastic component 328 tops were resisted against on roof 311, and locating part 315 agrees with in recess 330, allowed mainboard 32 to move up and down within the specific limits, but were unlikely to deviate from from housing 31; Simultaneously, locating part 315 has certain elasticity, can allow mainboard 32 to disassemble in the first side wall 313 of housing 31 and the gap between inwall 314 to locating part 315 application of forces.
Review Fig. 2, when mainboard 32 was arranged in print cartridge 3, mainboard 32 moved up and down along the direction that is parallel to the first side wall 313 under the guiding that is formed at the guide (not shown) between the first side wall 313 and inwall 314.Because the height of the aspect ratio inwall 314 of the first side wall 313 is little, it is all exposed outside housing 31 that part and mainboard 32 lower ends of chips 322 are installed on mainboard 32 tops; At this moment, mainboard 32 lower ends, namely the part that is in substrate 321 lower ends of the conductive strips on FPC 323 forms chip contacts; And the part of mainboard 32 tops installation chips 322 is exposed, is convenient to observation and replacing to chip.Referring to Fig. 6, because mainboard 32 can move up and down, chip contacts also can move up and down.In process on print cartridge 3 being installed to printer mounting portion 1, the chip contacts of mainboard 32 lower ends contacts and is subject to the power that electric contact 11 makes progress with electric contact 11, along with print cartridge 3 continue move down, elastic component 328 conflict roofs 311 also produce elastic deformation, chip contacts moves up with the relative box body of mainboard 32, thereby prevent that chip contacts from contacting with electric contact 11 rigidity, reduced the frictional force between chip contacts and electric contact 11; On the other hand, under the downward thrust of elastic component 328, chip contacts keeps stable electrical to be connected with electric contact 11.By the physical parameter of elastic component 328 is set, can regulate the size of pressure between chip contacts and electric contact 11, thereby on the basis that guarantees the stable electrical connection, reduce the frictional force between chip contacts and electric contact 11 as far as possible, thereby effectively reduce the wearing and tearing of chip contacts.
Obviously, guide is not limited to be molded over the guide rail of the 3rd sidewall 316 and the 4th sidewall 317 inboards, can be also the groove that self is surrounded by the first side wall 313, inwall 314, the 3rd sidewall 316 and the 4th sidewall 317.
In a further embodiment, chip substrate and mainboard substrate are one-body molded, and at this moment, the mainboard substrate does not just need to arrange buckle 324 and pin 329, thereby simplify the structure of mainboard substrate.In addition, the conductive strips that FPC 323 also can directly be fixed on the mainboard substrate replace, and like this, although conductive strips are non-removable, have simplified the structure of mainboard, thereby have facilitated the installation and removal of mainboard.
More than to embodiment of the present utility model and the explanation carried out around the dependency structure conversion of embodiment.But the utility model is not limited to technique scheme, for example, elastic component also can be arranged on spring, the block rubber between mainboard and print cartridge roof or have flexible sponge, and perhaps the part of mainboard installation chip can be not exposed outside housing yet, etc.Within these changes and equivalent transformation all should be included in the described scope of claim.
In above each embodiment, under the prerequisite that guarantees print cartridge ink storage chamber capacity, the corner part between the first side wall and diapire occupied space is far smaller than space occupied between the first side wall and inwall.Therefore, be arranged in mainboard between the first side wall and inwall and that can move within the specific limits and can design relatively largerly, thereby both can require to make lower mainboard and the associated components of production cost with lower processing technology; Can make again the parts such as mainboard have higher intensity and durability.On the other hand, the parts overwhelming majority such as mainboard and chip are disposed in housing between the first side wall and inwall, and chip contacts also can inside contract to housing receiving when pressing; Therefore, the appurtenances such as mainboard and chip can be effectively protected, and avoid breaking.If only mainboard is arranged in corner part between the first side wall and diapire or the first side wall outside, the appurtenances such as mainboard and chip are easily fallen the damage such as touches.
