The camera module 10 includes a camera module 11 and a first female connector 12 electrically connected to the camera module 11. The camera module 11 can capture an image of the position to be detected.

[0031] The adapter assembly 20 includes a second female connector 22 electrically connected to the first male connector 21, the first male connector 21 can be docked with the first female connector 12, and the second female connector 22 is electrically connected to the pipeline assembly 30. The adapter assembly 20 is electrically connected to the camera module 10 by docking the first male connector 21 with the first female connector 12, and transmits the image captured by the camera module 10 to the pipeline assembly 30, and then to the host.

[0032] The present application sets a camera module 10, an adapter assembly 20 and a pipeline assembly 30. The camera module 10 and the adapter assembly 20 are detachably connected. The camera module 10 includes a camera module 11 and a first female connector 12 electrically connected to the camera module 11. The adapter assembly 20 includes a first male connector 21 and a second female connector 22 electrically connected to the first male connector 21. The second female connector 22 is electrically connected to the pipeline assembly 30. The user can disassemble and replace the entire camera module 10 according to different imaging requirements, thereby meeting different imaging requirements to a greater extent. In addition, during the process of replacing the camera module 10, the adapter assembly 20 can connect the first female connector 12 of the camera module 10 through the first male connector 21 to achieve quick connection between the camera module 10 and the adapter assembly 20, thereby achieving connection between the camera module 10 and the host connected to the pipeline assembly 30.

[0033] Among them, the user can quickly replace the camera module 10 according to different imaging requirements, such as different depths of field, different imaging angles, different resolutions, different contrasts, etc.

[0034] In a specific implementation, the first female connector 12 may include a main connector 121 and a plurality of electrical connection spring pins 122. The main connector 121 is provided with a plurality of docking holes, and the electrical connection spring pins 122 are correspondingly provided in one of the docking holes. The number of the electrical connection spring pins 122 may be two or more, and the number may be set according to the number of signal lines between the camera module 10 and the pipeline assembly 30. Correspondingly, the number of the docking holes may be two or more.

[0035] The electrical connection spring pin 122 can provide a reliable electrical connection, so that stable data transmission or power transmission can be carried out between the camera module 10 and the adapter assembly 20; the electrical connection spring pin 122 can transmit various types of signals, including digital signals, analog signals and power signals, thereby realizing communication and energy transmission between the camera module 10 and the adapter assembly 20; the electrical connection spring pin 122 has a certain elasticity, providing mobile connection elasticity, thereby ensuring that the electrical connection stability is maintained when the camera module 10 and the adapter assembly 20 vibrate or move.

When the second male connector 32 is docked with the first female connector 12, the electrical connecting spring pin 122 of the second male connector 32 is inserted into the docking hole of the first female connector 12, and electrically connected with the electrical connecting spring pin 122 of the first female connector 12 in a one-to-one correspondence.

[0037] The second female socket connector 22 may have the same structure as the first female socket connector 12 .

[0038] refer to Figure 5In this embodiment, the camera module 11 includes a lens 111 and a circuit board 112 electrically connected to the lens 111. The circuit board 112 is provided with electrical connection contacts, and the electrical connection end of the first female connector 12 is welded to the electrical connection contacts.

[0039] The electrical connection end of the first female connector 12 is directly welded to the electrical connection contact of the circuit board 112 by welding, without the need to use a connecting wire or FCP (Flexible Printed Circuit Board) soft board to achieve the connection. Compared with the method in which the first female connector 12 is connected to the circuit board 112 via an FPC board, the direct welding method of the present application reduces the number of connecting components, reduces the failure rate, and makes the overall structure simpler, occupies less space, and has a more compact structure; the welding connection method is relatively simple and more convenient for maintenance, which can reduce the time and cost of repairing and replacing parts; it provides a more stable connection, reduces the contact resistance between the connecting components, helps to improve the reliability and stability of the connection, and reduces the problems caused by failures of the connecting wires or flexible circuit boards.

[0040] In a specific implementation, the electrical connection end of the first female socket connector 12 corresponds to the electrical connection spring pin 122 , and one end of the electrical connection spring pin 122 is directly welded to the electrical connection contact of the circuit board 112 , so that the first female socket connector 12 is electrically connected to the circuit board 112 .

[0041] The circuit board 112 is provided with relevant circuits, such as a power supply circuit, which is electrically connected to the lens 111 to provide a working voltage for the lens 111 .

[0042] Further, refer to Figure 5 The camera module 11 also includes an image processing chip 113 and a mounting bracket 114. The mounting bracket 114 is provided with a lens 111 mounting hole and an avoidance hole. The lens 111 is at least partially accommodated in the lens 111 mounting hole. The image processing chip 113 is electrically connected to the lens 111 and the circuit board 112 respectively, and the image processing chip 113 is arranged on the end of the circuit board 112 close to the lens 111 and accommodated in the avoidance hole.

[0043] By setting a lens 111 mounting hole and an avoidance hole on the mounting bracket 114 to accommodate the mounting lens 111 and the image processing chip 113, the lens 111 is installed and positioned, so that the overall structure of the camera module 10 is stable and compact, and the entire camera module 10 is easy to replace to meet different imaging requirements.

[0044] The image processing chip 113 can convert optical signals into electronic signals for digital processing and transmission. Specifically, the image processing chip 113 converts the optical signals captured by the lens 111 into electronic signals, and processes the electronic signals, including operations such as contrast enhancement, color adjustment, and noise reduction, to improve the image quality and clarity, and transmits the processed electronic signals to the circuit board 112, and then transmits them to the host through the adapter component 20 and the pipeline component 30, and is connected to a display screen or other device for real-time observation or recording.

[0045] refer to Figures 4 to 6 In this embodiment, the camera module 10 also includes a first shell 13, the camera module 11 and the first female socket connector 12 are arranged in the first shell 13, and an internal thread 131 is provided on the inner wall of the first shell 13.

[0046] By means of the first external thread 231 and the second external thread 232 which are arranged at intervals along the axial direction of the connecting shell 23 on the outer periphery of the connecting shell 23, the first outer shell 13 can be connected to the connecting shell 23 through the internal thread 131 and the first external thread 231 or the second external thread 232. In practical application, the first external thread 231 is arranged away from the camera module 11 of the camera module 10, and the second external thread 232 is arranged close to the camera module 11 of the camera module 10. When the camera module 10 is assembled with the adapter assembly 20, the internal thread 131 of the first outer shell 13 is connected with the first external thread 231. During use of the endoscope device, the first outer shell 13 of the camera module 10 may rotate relative to the connecting shell 23, thereby causing the internal thread 131 of the first outer shell 13 to detach from the originally connected first outer thread 231. Since the second outer thread 232 is also provided on the outer periphery of the connecting shell 23, the internal thread 131 of the first outer shell 13 can also be connected to the second outer thread 232, thereby preventing the first outer shell 13 from detaching from the connecting shell 23 to a certain extent.

[0047] Furthermore, a first limiting boss 233 is provided on the outer periphery of the connecting shell 23 along its own circumferential direction, and the first limiting boss 233 and the second external thread 232 are provided on both sides of the first external thread 231. After the connecting shell 23 is connected to the first outer shell 13 through the cooperation of the internal thread 131 and the first external thread 231, the first limiting boss 233 abuts against the rear end of the first outer shell 13.

[0048] The first limiting boss 233 on the outer periphery of the connecting shell 23 can limit the depth of the first housing 13 sleeved on the connecting shell 23, and can ensure effective electrical connection between the first female connector 12 and the first male connector 21. When the camera module 10 needs to be replaced, the first housing 13 can be rotated to separate the first housing 13 from the connecting shell 23, and the first female connector 12 and the first male connector 21 are disconnected electrically, which is very convenient to operate.

[0049] Further, Figure 1 , Figure 5 and Figure 6 The endoscope device also includes a sealing member 40 , which is sleeved on the outer periphery of the connecting shell 23 , and after the connecting shell 23 is connected to the first outer shell 13 , the sealing member 40 is clamped between the first limiting boss 233 and the rear end of the first outer shell 13 .

[0050] By providing the sealing member 40 , the gap between the first shell 13 and the connecting shell 23 can be sealed, thereby ensuring the sealing between the first shell 13 and the connecting shell 23 and preventing dust or water droplets from entering through the gap between the first shell 13 and the connecting shell 23 .

[0051] refer to Figure 5 In this embodiment, the camera module 10 also includes a first positioning shell 14 and a second positioning shell 15 fixedly connected to the first positioning shell 14, the first female socket connector 12 is installed on the first positioning shell 14, the second positioning shell 15 is covered on the outer periphery of the camera module 11, and a second limiting boss 132 is provided on the inner wall of the first outer shell 13. After the first outer shell 13 is connected to the connecting shell 23, the second limiting boss 132 abuts against the front end of the second positioning shell 15 to limit the first positioning shell 14 and the second positioning shell 15 in the first outer shell 13.

[0052] The first female socket connector 12 is positioned and installed by setting a first positioning shell 14, and the second positioning shell 15 is covered on the outer periphery of the camera module 11. After the first outer shell 13 is connected to the connecting shell 23, the second limiting boss 132 abuts against the front end of the second positioning shell 15, and the first positioning shell 14 and the second positioning shell 15 are limited in the first outer shell 13 to prevent them from moving or misaligning during use, thereby limiting the camera module 11 and the first female socket connector 12 in the first outer shell 13, so that the first female socket connector 12 and the first male connector 21 of the adapter assembly 20 remain electrically connected.

[0053] Furthermore, an outer edge protrusion 1211 is convexly provided on the outer periphery of the first female socket joint 12, a first limiting protrusion 141 is convexly provided on the inner wall of the first positioning shell 14, and the outer edge protrusion 1211 is clamped between the first limiting protrusion 141 and the rear end of the second positioning shell 15.

[0054] By clamping the outer edge protrusion 1211 of the first female socket connector 12 between the first limiting protrusion 141 and the rear end of the second positioning shell 15, the first female socket connector 12 is further positioned, so that the first female socket connector 12 is not easily displaced and loosened along its own axial direction, thereby ensuring the firmness of the connection.

[0058] The sealing member 40 is specifically a sealing ring. An accommodating groove is provided on the outer periphery of the connecting shell 23, and the sealing ring is confined in the accommodating groove.

[0059] The number of the second limiting protrusions 1212 can be one, two, or more than two. Preferably, in this embodiment, the first female connector 12 is provided with three second limiting protrusions 1212 along its own axial direction, and the three second limiting protrusions 1212 are arranged at intervals along the circumference of the first female connector 12. Correspondingly, three limiting grooves 151 corresponding to the positions are arranged on the second positioning shell 15, and each second limiting protrusion 1212 is correspondingly accommodated in a limiting groove 151. The second limiting protrusions 1212 form a three-point limit to limit the circumferential rotation of the first female connector 12, thereby ensuring a stable electrical connection between the first female connector 12 and the first male connector 21.

[0060] In specific configuration, the second limiting protrusion 1212 is disposed on the main seat 121 .

In addition, the second outer shell 31 can be inserted between the outer wall of the inner shell 24 and the inner wall of the connecting shell 23, and can limit the docking of the second male connector 32 and the second female connector 22, which can help users quickly dock the second male connector 32 with the second female connector 22.

[0063] In other embodiments, the second female socket connector 22 of the adapter assembly 20 may also be electrically connected to the pipeline assembly 30 in other ways. For example, the electrical connection line of the pipeline assembly 30 is directly electrically connected to the second female socket connector 22 of the adapter assembly 20 .

[0064] The docking method between the second male connector 32 and the second female connector 22 is the same as the docking method between the first male connector 21 and the first female connector 12, and will not be described in detail here.
