However, since the FPC is flexible, the gold finger connection end of the FPC needs to be inserted into the FPC connection terminal on the PCB board of the printing device body first, and then the quick-insert printer core is inserted into the printing device body, resulting in inconvenient insertion. Moreover, when removing the quick-insert printer core, the gold finger of the FPC also needs to be pulled out from the PCB additionally, which affects the insertion and removal speed of the quick-insert printer core. Therefore, this problem needs to be solved. Summary of the Utility Model

[0031] Embodiment 1

[0032] As Figures 2 to 5As shown in the figure, this embodiment discloses a quick-insert printer core, including a core body 1, an FPC positioning bracket 2, and an FPC positioning sleeve 3. It is defined that the core body 1 is inserted into the printing device in the up-down direction. The FPC positioning bracket 2 is connected (by screws 6 or other means) below the core body 1. The FPC positioning sleeve 3 is sleeved outside the FPC positioning bracket 2. The FPC 8 on the core body 1 passes through the gap between the FPC positioning bracket 2 and the FPC positioning sleeve 3, and the FPC positioning bracket 2 and the FPC positioning sleeve 3 cooperate to position the four sides of the FPC 8.

[0033] The FPC positioning bracket 2 includes a horizontal portion 21 and a vertical portion 22 connected to the bottom surface of the horizontal portion 21. A first through groove 23 is provided on the horizontal portion 21, and a second through groove 31 is provided on the FPC positioning sleeve 3. The FPC positioning sleeve 3 is sleeved outside the vertical portion 22 of the FPC positioning bracket 2 through the second through groove 31. A gap for accommodating the FPC is formed between the groove wall of the second through groove and the vertical portion 22. The FPC 8 passes through the second through groove 31 to expose the gold fingers at the bottom surface of the FPC positioning sleeve 3, so that the gold fingers of the FPC 8 can be inserted into the FPC connector 4 on the PCB board 5 of the printing device main body.

[0034] The vertical portion 22 is provided with a protruding structure that contacts the left and right sides of the FPC. Two positioning ears 9 are formed by local outward protrusion on both sides of the FPC. The protruding structure at least abuts against the upper surfaces of the two positioning ears 9. In a specific structure, the vertical portion 22 has a vertical positioning surface 24. The protruding structure includes two positioning bumps 10 provided on the positioning surface of the vertical portion 22. The FPC 8 on the core body 1 passes through the first through groove 23 and is in parallel contact with the positioning surface 24. Two positioning ears 9 are formed by local outward protrusion on both sides of the FPC 8. The FPC 8 is inserted between the two positioning bumps 10. The two side edges of the FPC 8 are respectively in contact with the two positioning bumps 10 to achieve left-right positioning of the FPC. The two positioning bumps 10 are respectively located above the same-side positioning ears 9 and respectively abut against the upper surfaces of the same-side positioning ears 9. The two positioning bumps 1 perform left-right positioning on the FPC 8 and are also used to apply a downward thrust to the FPC 8 to prevent the FPC 8 from retreating when the gold fingers of the FPC 8 are inserted into the printing device main body. When the quick-insert printer core is inserted into the printing device main body, the positioning bumps 10 push down the FPC 8 to insert the gold fingers into the FPC connector 4 on the PCB board of the printing device main body, and the positioning bumps 10 prevent the gold fingers of the FPC 8 from retreating.

[0035] The width of the second through groove 31 is adapted to the width of the FPC 8. The second through groove 31 is a rectangular groove. Three groove walls of the second through groove 31 cooperate with the positioning surface 24 on the FPC positioning bracket 2 to perform contact positioning on the four surfaces (front, back, left, and right) of the FPC 8.

[0036] In this embodiment, both the positioning bump 10 and the positioning ear 9 are square. One side of the positioning bump 10 is parallel to and in contact with the side of the FPC 8, and the bottom surface of the positioning bump 10 is used to push the positioning ear 9 downward. In other embodiments, the shapes of the positioning bump 10 and the positioning ear 9 are not limited to this. For example, the positioning bump 10 and the positioning ear 9 can also be triangular.

Specifically, the surface of the FPC positioning sleeve 3 is provided with a protruding snap block 32, and the FPC positioning bracket 2 is provided with a snap 25 (specifically installed on the bottom surface of the horizontal portion 21). The snap 25 snaps the snap block 32 from top to bottom. In this way, the cooperation between the snap 25 and the snap block 32 realizes the clamping connection between the FPC positioning sleeve 3 and the FPC positioning bracket 2. The snap block 32 on the FPC positioning sleeve 3 can also be changed to a slot, or the slot can be provided on the FPC positioning bracket 2, and the snap 25 can be provided on the FPC positioning sleeve 3.

[0038] In order to improve the assembly accuracy of the FPC positioning sleeve 3, vertical guiding columns 26 are provided on both sides of the vertical portion 22, and vertical positioning holes 33 are provided on both sides of the FPC positioning sleeve 3. The positioning holes 33 and the guiding columns 26 are in one-to-one correspondence for hole-shaft fit. The cooperation between the guiding columns 26 and the positioning holes 33 realizes the assembly positioning of the FPC positioning sleeve 3 and the FPC positioning bracket 2, ensuring the installation accuracy of the FPC positioning sleeve 3 and enabling the gold fingers of the FPC 8 to smoothly pass through the FPC positioning sleeve 3. In order to facilitate the insertion of the guiding column 26 into the positioning hole 33, a chamfer is provided at the lower end of the guiding column 26. Preferably, the positioning hole 33 is a side-opening hole, which has a clamping effect on the guiding column 26, and the FPC positioning sleeve 3 is not easily detached from the FPC positioning bracket 2 after being installed. The guiding column 26 and the positioning hole 33 are preferably circular, but are not limited to this.

[0039] In this embodiment, the snap 25 is provided on the front side and / or the rear side of the FPC positioning bracket 2, and the two guiding columns 26 are respectively provided on the left and right sides of the FPC positioning bracket 2. In other embodiments, the snap 25 can also be provided on the left side and / or the right side of the FPC positioning bracket 2, and the two guiding columns 26 can also be respectively provided on the front side and the rear side of the FPC positioning bracket 2.

The quick-insert printer core is detachably inserted into the printing device main body. The printing device main body includes a PCB board 5, on which an FPC connector 4 (i.e., an electrical connection terminal) is installed. The FPC connector 4 performs precise positioning with the gold fingers of the FPC 8 on the quick-insert core. On the PCB board 5, one alignment hole 7 is provided on each side of the FPC connector 4, and the two alignment holes 7 cooperate with the two alignment posts 26 on the quick-insert printer core for precise positioning. The alignment posts on the FPC positioning bracket 2 are used for precise positioning with the printing device main body and at the same time for precise positioning with the FPC positioning sleeve 3.

[0041] This embodiment also provides another printing device, which includes a quick-insert printer core and a printing device main body. The quick-insert printer core is detachably inserted into the printing device main body. The printing device main body includes an FPC and a PCB board. One end of the FPC is connected to the PCB board through gold fingers, and the other end of the FPC is provided with an FPC connector 4 for plugging and connecting with the gold fingers of the FPC on the quick-insert printer core. The FPC connector 4 is inserted into the lower end interior of the FPC positioning sleeve 3 to achieve positioning around.
