[0048] The first conductive elastic sheet 315 and the second conductive elastic sheet 324 are electrically connected to the first conductive part 313 and the second conductive part 314 respectively. The first conductive part 313 and the second conductive part 314 are electrically connected to the first conductive element 57 and the second conductive element 58 respectively, so that the first conductive elastic sheet 315 and the second conductive elastic sheet 324 are electrically connected to the first conductive element 57 and the second conductive element 58 respectively, avoiding direct thermal processing on the battery 21, and the first conductive elastic sheet 315 and the second conductive elastic sheet 324 can realize elastic extrusion installation of the battery 21, having the advantages of firm structure and good axial connection of the battery 21.

The first connecting pieces 331 can be in sheet structure or linear structure, for example, the first connecting pieces 331 are plastic hard sheets or soft sheets or metal sheets. The installation space of the connecting piece 33 in the radial direction is reduced.

[0051] In combination Figure 4 As shown in Embodiment 2, the first conductive element 57 and the second conductive element 58 are arranged on both sides of the battery 21. The first connecting part 51 of the first conductive element 57 is fixed to the side of the first fixed sheet 31 away from the battery 21, and the first connecting part 51 of the second conductive element 58 is fixed to the side of the second fixed sheet 32 away from the battery 21.

[0053] A structure of the conductive spring, the conductive spring comprises a spring body, and a circular arc spring part 352 protruding from the spring body to the direction of the battery 21. The metal element 312 forms the spring body, and the spring body extends along the electrode side of the battery 21, or the end of the spring body is fixedly connected with the end of the third connecting piece 333.

[0055] In combination Figure 5 As shown, further, the capsule endoscope mainly consists of two parts: a shell 1 and a core assembly arranged in the shell 1.

The shell 1 comprises a cylindrical part 11 and two arc parts 12 arranged at the two ends of the cylindrical part 11, and the battery assembly 2, the PCB board 4 and the camera 6 are arranged in the cylindrical part 11, and the magnet 7 is arranged in one arc part 12.

[0056] The PCB board 4 is arranged on one side or both sides of the battery 21 and connected with the battery 21. The PCB board 4 is closer to the battery assembly 2 than the camera, and the camera 6 and the magnet 7 are arranged on opposite sides of the battery 21. Specifically, the camera 6 is arranged in the region close to the arc part 12 in the cylindrical part 11, and the arc part 12 close to the camera 6 is generally defined as the front, that is, the magnet 7 is arranged in the arc part 12 on the rear side. Since the density and total weight of the magnet 7 are large, the influence on the overall center of gravity of the capsule endoscope is large. When the magnet 7 is fixed in the arc part 12 on the rear side, the space is fully utilized, and the overall center of gravity is close to the region of the magnet. This makes the arc part 12 on the front side easy to tilt at a certain angle in the liquid, rather than lying flat on the stomach wall or intestinal wall. In the prior art, the magnet 7 is generally fixed in the middle region of the cylindrical part 11. Compared with the prior art, it has been proved in practice that the field of view of the capsule endoscope of the present application is wider, and the observation of the structure of the digestive tract cavity is clearer and more complete.

[0057] Further, the magnet 7 has a circular-arc-shaped outer wall which is in close contact with the inner wall of the circular-arc part 12, wherein the magnet 7 fills the circular-arc-shaped inner cavity of the circular-arc part 12 and is fixed to the inner wall of the circular-arc part 12 by glue. In this way, the front circular-arc part 12 is more easily tilted by a certain angle, and the field of view is wider.

[0058] Further, the inner diameter of the shell 1, the outer diameter of the battery compartment 34 and the outer diameter of the battery 21 are of the same size, the difference between the inner diameter of the shell 1 and the outer diameter of the battery compartment 34 is within 1mm, and the difference between the inner diameter of the battery compartment 34 and the outer diameter of the battery 21 is within 1mm. In this way, it can be ensured that the connecting assembly 3 and the battery 21 will not be obviously displaced along the radial direction of the shell 1.

[0059] In combination Figure 6 As shown, the second connecting part 52 is a buckle which is formed by extending the first connecting part 51 towards the PCB board.

Preferably, the buckle body 521 is perpendicularly connected with the first connecting part 51. It can be understood that the length of the first connecting part 51 is greater than the width of the mounting hole 41.

[0060] The first and second elastic clamping parts are respectively provided as elastic clamping pieces which are connected to the buckle body 521. The first and second elastic clamping parts can be provided on one side of the buckle body 521, or on both sides of the buckle body 521, or can be radially outwardly extended along the circumferential direction of the buckle body 521.

[0061] In combination Figure 7 And Figure 8 As shown, the first elastic clamping part is a first clamping piece 53 which is laterally protruded from the buckle body 521, and the first clamping piece 53 can be provided as one or more than one, and can be provided on one side or both sides of the buckle body 521 or can be radially outwardly extended along the circumferential direction of the buckle body 521. The first clamping piece 53 is formed with an abutting part 54 which abuts against the inner wall 42 of the mounting hole.

[0062] Specifically, one part of the first clamping piece 53 is connected with the buckle body 521, and the other part is not connected with the buckle body 521. The other part of the first clamping piece 53 is formed with the abutting part 54 which abuts against the inner wall 42 of the mounting hole. The abutting part 54 can be pressed under the action of an external force, and can be outwardly opened without the external force, and has good strength and freedom.

[0063] In the embodiment 3 of the present application, one end of the first clamping piece 53 is connected with the buckle body 521, and the other end opposite to the one end is a first free end, and the first free end forms the abutting part 54. The number of the abutting parts 54 can be one or more than one.

[0064] In combination Figure 9 As shown, further, in embodiment 3, the first card 53 is arranged on one side of the buckle body 521, and when the buckle 52 is not inserted into the mounting hole 41, the distance L1 between the first free end and the other side of the buckle body 521 is greater than the width D of the mounting hole 41, so that the mounting hole inner wall 42 can press the abutting portion 54, so that the electrical connection between the abutting portion 54 and the mounting hole inner wall 42 is stable. The distance H2 between the abutting portion 54 and the first connecting portion 51 is less than the depth T of the mounting hole 41, H2

[0065] By reasonable structure, d

[0066] Further, in embodiment 3, the second elastic clamping portion is a second card 55 arranged on one side of the buckle body 521 and spaced apart from the first card 53, and the second card 55 has a second free end 551. The second card 55 can be provided as one or more than one, preferably, the second card 55 is provided as two. In the depth direction of the mounting hole 41, the abutting portion 54 is closer to the first connecting portion 51 than the second free end 551. The distance H1 between the second free end 551 and the first connecting portion 51 is greater than the depth T of the mounting hole 41, H1

[0067] Furthermore, in embodiment 3, the buckle body 521 is provided with through holes 522 having the same shape as the first card 53 and the second card 55. One end of the first card 53 and the second card 55 are respectively fixed to the edge of the through hole 522, and the other ends of the first card 53 and the second card 55 are respectively designated as the first free end and the second free end 551. The first card 53 and the second card 55 are connected to the buckle 52 by the edge of one end, while the remaining parts are cut off from the buckle 52, causing the remaining parts of the first card 53 and the second card 55 to open outward. This has the advantages of simple processing and easy implementation.

[0068] Combination Figure 10 As shown, in embodiment 4, both ends of the first card 53 are connected to the buckle body 521, and the middle positions of the two first cards 53 respectively protrude to form two opposing abutment portions 54. When the buckle 52 is not inserted into the mounting hole 41, the distance L2 between the two abutment portions 54 is greater than the width D of the mounting hole 41. L2 > D allows the inner wall 42 of the mounting hole to press against the abutment portion 54, thus maintaining a stable electrical connection between the abutment portion 54 and the inner wall 42 of the mounting hole. The distance H4 between the abutment portion 54 and the first connecting portion 51 is less than the depth T of the mounting hole 41. H4 < T ensures that the abutment portion 54 will not pass through the mounting hole 41 during installation, and the abutment portion 54 maintains good electrical contact with the inner wall 42 of the mounting hole.

[0069] Preferably, in embodiment 4, the second elastic snap-fit ​​portion is a third card 56 formed by extending the snap-fit ​​body 521 to one side and having a third free end 561. The third card 56 is offset from the first card 53. It can be understood that the function of the third card 56 is the same as that of the second card 55 in embodiment 3. In the depth direction of the mounting hole 41, the abutment portion 54 is closer to the first connecting portion 51 than the third free end 561.

[0070] In embodiment 4, the distance H3 between the third free end 561 and the first connecting part 51 is greater than the depth T of the mounting hole 41. H3 > T ensures that the third card 56 can pass through the mounting hole 41. The two first cards 53 are symmetrically arranged with the center line between one side and the other side of the buckle body 521. The distance L3 between the third free end 561 and the aforementioned center line is greater than 1 / 2 of the width D of the mounting hole 41. This allows the third card 56 to open outward after passing through the mounting hole 41, with the third free end 561 extending beyond the edge of the mounting hole 41, so that the PCB board 4 does not detach from the third card 56. This achieves the purpose of the PCB board 4 being snapped between the first connecting part 51 and the second elastic snap-fit ​​part.

Then, the first connecting part 51 and the second connecting part 52 of the conductive element 5 are respectively electrically connected with the conductive springs and the PCB 4, and the purpose of electrically connecting the electrodes of the battery 21 with the PCB 4 is achieved. The application has the advantages of convenient installation, stable and reliable structure, and stable electrical connection.
