Specific embodiments

[0046] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0047] The core of the present utility model is to provide a capsule core, which can fix the planar mounting position of the first circuit board relative to the second circuit board, and at the same time, through the clamping member, the second circuit board can be prevented from tilting relative to the first circuit board.

[0048] Another object of the present utility model is to provide a capsule endoscope including the above-mentioned capsule core.

[0049] This specific embodiment discloses a capsule core, which includes a first circuit board 200, a second circuit board 300 and a clamping member 600. The second circuit board 300 is arranged on the upper side of the first circuit board 200 and is connected to the first circuit board 200 through an FPC flexible cable 400. The surface of the first circuit board 200 facing the second circuit board 300 is provided with protruding components, and the second circuit board 300 is provided with a limiting member for limiting the position of the components, so as to limit the planar mounting position of the first circuit board 200 relative to the second circuit board 300. The clamping member 600 is provided with a first card slot 610 and a second card slot 620. The first circuit board 200 is clamped in the first card slot 610, and the second circuit board 300 is clamped in the second card slot 620, so as to limit the distance between the first circuit board 200 and the second circuit board 300.

[0050] It should be noted that the limiting member mentioned in this specific embodiment is mainly used to limit the mounting position of the second circuit board 300 relative to the first circuit board 200 in the plane where the first circuit board 200 is located, so as to prevent the second circuit board 300 from displacing relative to the first circuit board 200 in the plane where the first circuit board 200 is located. The bonding and fixing member is mainly used to limit the mounting position of the second circuit board 300 relative to the first circuit board 200 perpendicular to the plane where the first circuit board 200 is located, so as to limit the distance between the second circuit board 300 and the first circuit board 200 in the direction perpendicular to the plane where the first circuit board 200 is located.

[0051] The component mentioned in this specific embodiment can be a CPU chip 210, or other structures that meet the requirements, which are specifically determined according to the actual situation and will not be elaborated here.

[0052] It should be noted that the number of the components mentioned in the above embodiment can be one or more. The specific setting position of the components can be located at the center position of the first circuit board 200, or can be determined according to the actual situation, which is specifically determined according to the actual situation and will not be elaborated here.

[0053] During the process of using the capsule core device provided in this specific embodiment, during the installation of the first circuit board 200 and the second circuit board 300 connected by the FPC flexible cable 400, first, align the components on the first circuit board 200 with the limiting members to limit the installation position of the first circuit board 200 relative to the second circuit board 300 in the plane where the second circuit board 300 is located; then install the clamping member 600 so that the first circuit board 200 is clamped in the first card slot 610 and the second circuit board 300 is clamped in the second card slot 620, so as to fix the installation position of the first circuit board 200 relative to the second circuit board 300 in the direction perpendicular to the plane where the first circuit board 200 is located, and prevent the second circuit board 300 from tilting relative to the first circuit board 200.

[0054] Compared with the prior art, the capsule core provided in this specific embodiment can fix the installation position of the first circuit board 200 relative to the second circuit board 300 in the plane and the vertical installation position, and can prevent the first circuit board 200 from tilting relative to the second circuit board 300.

[0055] In a specific embodiment, as Figure 1 shown, the clamping member 600 can be installed on the side of the first circuit board 200 or the second circuit board 300 opposite to the connection with the FPC flexible cable 400.

[0056] In this specific embodiment, the clamping member 600 is arranged away from the FPC flexible cable 400. After the first circuit board 200 is clamped in the first card slot 610 and the second circuit board 300 is clamped in the second card slot 620, it is equivalent to fixing the first circuit board 200 and the second circuit board 300 at the position farthest from the FPC flexible cable 400, making the size of the acting force arm of the clamping member 600 reach the maximum, which is more convenient to limit the first circuit board 200 and the second circuit board 300.

[0057] On the basis of the above embodiment, as Figure 4 shown, a limiting bottom surface 6101 can be set in the first card slot 610, and the limiting bottom surface 6101 is used to contact the surface of the first circuit board 200 on the side facing away from the second circuit board 300; due to the elastic restoring force of the FPC flexible cable 400, the first circuit board 200 has a tendency to move away from the second circuit board 300 relatively. Under the action of the elastic restoring force of the FPC flexible cable 400, the surface of the first circuit board 200 on the side facing away from the second circuit board 300 contacts the limiting bottom surface 6101 to limit the installation position of the first circuit board 200; as Figure 3As shown, the second card slot 620 is provided with a limiting top surface 6201, and the limiting top surface 6201 is used to contact the surface of the second circuit board 300 on the side away from the first circuit board 200; due to the elastic restoring force of the FPC soft flat cable 400, the second circuit board 300 has a tendency to move relatively away from the first circuit board 200. Under the action of the elastic restoring force of the FPC soft flat cable 400, the surface of the second circuit board 300 on the side away from the first circuit board 200 is brought into contact with the limiting top surface 6201, thereby limiting the installation position of the second circuit board 300.

[0058] Furthermore, the limiting bottom surface 6101 and the limiting top surface 6201 can both be planes, and the limiting bottom surface 6101 and the limiting top surface 6201 can be parallel to each other; so that the limiting bottom surface 6101 is in surface contact with the first circuit board 200, and the limiting top surface 6201 is in surface contact with the second circuit board 300, thereby improving the stability of the first circuit board 200 and the second circuit board 300 during the limiting process.

[0059] Based on the above embodiments, a first limiting side 6102 can be set in the first card slot 610, and the first limiting side 6102 is used to contact the outer peripheral side of the first circuit board 200; the second card slot 620 is provided with a second limiting side 6202, and the second limiting side 6202 is used to contact the outer peripheral side of the second circuit board 300.

[0060] During the actual assembly process, when the first circuit board 200 is inserted into the first slot 610, when the outer side surface of the first circuit board 200 contacts the first limiting side surface 6102, it indicates that the first circuit board 200 is installed in place; when the second circuit board 300 is inserted into the second slot 620, when the outer side surface of the second circuit board 300 contacts the second limiting side surface 6202, it indicates that the second circuit board 300 is installed in place.

[0061] Further, if Figure 1 As shown, the capsule core also includes a power supply 100, such as Figure 2 As shown, the first circuit board 200 is arranged at one axial end of the power supply member 100, and the clamping member 600 is provided with a supporting portion 640, the bottom surface of the supporting portion 640 is in contact with the surface of the power supply member 100 facing the first circuit board 200, and the upper surface of the supporting portion 640 is used to contact the lower surface of the first circuit board 200.

[0062] The supporting portion 640 can fill the gap between the first circuit board 200 and the power supply 100 to prevent the first circuit board 200 from being partially suspended, thereby effectively improving the installation stability of the first circuit board 200 .

[0063] Based on the above embodiments, the limiting member may include a first limiting member and a second limiting member. The first limiting member is used to limit the installation position of the first circuit board 200 relative to the second circuit board 300 in a first direction, and the second limiting member is used to limit the installation position of the first circuit board 200 relative to the second circuit board 300 in a second direction; the first direction is perpendicular to the second direction.

[0064] Specifically, the first limiting member includes a first limiting protrusion 320 and a second limiting protrusion 330 disposed on the second circuit board 300, and the second limiting member includes a third limiting protrusion 340 and a fourth limiting protrusion 350 disposed on the second circuit board 300; the first limiting protrusion 320 is provided with a first limiting surface for contacting the outer peripheral side surface of the component, and the second limiting protrusion 330 is provided with a second limiting surface for contacting the outer peripheral side surface of the component; the first limiting surface and the second limiting surface are oppositely arranged; the third limiting protrusion 340 is provided with a third limiting surface for contacting the outer peripheral side surface of the component, and the fourth limiting protrusion 350 is provided with a fourth limiting surface for contacting the outer peripheral side surface of the component; the third limiting surface and the fourth limiting surface are oppositely arranged.

[0065] As Figure 6 shown, the component is a CPU chip 210 fixedly arranged on the first circuit board 200. The outer shape of the CPU chip 210 is rectangular. As Figure 5 shown, the first limiting protrusion 320, the second limiting protrusion 330, the third limiting protrusion 340, and the fourth limiting protrusion 350 are all electrical components installed on the second circuit board 300. Among them, the first limiting surface of the first limiting protrusion 320, the second limiting surface of the second limiting protrusion 330, the third limiting surface of the third limiting protrusion 340, and the fourth limiting surface of the fourth limiting protrusion 350 are respectively in contact with the four side surfaces of the CPU chip 210 to limit the installation position of the CPU chip 210, thereby limiting the planar installation position of the second circuit board 300 relative to the first circuit board 200. As Figure 5 shown, the placement position 310 surrounded by the first limiting protrusion 320, the second limiting protrusion 330, the third limiting protrusion 340, and the fourth limiting protrusion 350 is used to accommodate the CPU chip 210.

[0066] Furthermore, guide inclined surfaces may be provided at one ends of the first limiting protrusion 320, the second limiting protrusion 330, the third limiting protrusion 340, and the fourth limiting protrusion 350 facing the first circuit board 200, so that the component enters the space surrounded by the first limiting protrusion 320, the second limiting protrusion 330, the third limiting protrusion 340, and the fourth limiting protrusion 350, thereby improving the assembly efficiency of the first circuit board 200 and the second circuit board 300.
