[0054] Please see Figures 1 to 4 The PCB adapter board mounting box 10 of this utility model embodiment is used to mount the PCB adapter board 20. The PCB adapter board 20 is provided with fixing ears 21 on both sides. The PCB adapter board mounting box 10 includes:

[0055] The shielding upper shell 11 includes a first long sidewall 111 and a second long sidewall 112 disposed opposite to each other; and

[0056] The shielding lower shell 12 is configured to cooperate with the shielding upper shell 11. The shielding lower shell 12 includes a third long side wall 121 and a fourth long side wall 122 that are disposed opposite to each other. The first long side wall 111 and the fourth long side wall 122 are connected and fixed together, and the second long side wall 112 and the third long side wall 121 are connected and fixed together.

[0057] A first mounting groove 1111 is provided on the first long sidewall 111 and a second mounting groove 1121 is provided on the second long sidewall 112, and / or a third mounting groove 1211 is provided on the third long sidewall 121 and a fourth mounting groove 1221 is provided on the fourth long sidewall 122.

[0058] The first mounting groove 1111 and / or the fourth mounting groove 1221 constitute a first fixing port 13 for fixing one fixing ear 21, and the second mounting groove 1121 and / or the third mounting groove 1211 constitute a second fixing port 14 for fixing another fixing ear 21.

[0059] In the PCB adapter board mounting box 10 of this utility model embodiment, the upper shielding shell 11 and the lower shielding shell 12 are set as the mounting structure of the PCB adapter board 20, which can achieve better anti-interference and anti-radiation effects, and ensure that the normal function of the PCB adapter board 20 is not affected by interference and radiation.

[0060] Furthermore, since the PCB adapter board 20 is provided with fixing ears 21 on both sides, according to the actual structure of the PCB adapter board 20, a first mounting groove 1111 is provided on the first long sidewall 111 and a second mounting groove 1121 is provided on the second long sidewall 112, and / or a third mounting groove 1211 is provided on the third long sidewall 121 and a fourth mounting groove 1221 is provided on the fourth long sidewall 122. This makes the first mounting groove 1111 and / or the fourth mounting groove 1221 form a first fixing port 13 for fixing one fixing ear 21, and the second mounting groove 1121 and / or the third mounting groove 1211 form a second fixing port 14 for fixing another fixing ear 21. The structure of the PCB adapter board mounting box 10 is simple, and no additional fasteners or other installation structures are required to achieve stable installation of the PCB adapter board 20 in the PCB adapter board mounting box 10, further ensuring the stability of signal transmission and conversion.

[0061] Specifically, the PCB adapter board mounting box 10 in this embodiment is roughly in the shape of a relatively flat rectangle, which can stably mount the PCB adapter board 20 while controlling its own size and reducing the space occupied by the endoscope 1000.

[0062] Both the upper shielding shell 11 and the lower shielding shell 12 can be made of metal materials with anti-interference and anti-radiation properties, such as SUS304 metal materials. These materials can not only achieve good electromagnetic shielding, but also have good strength and hardness, which can extend the service life of the PCB adapter board mounting box 10.

[0063] Moreover, the upper shielding shell 11 and the lower shielding shell 12 are both integrally formed, which can simplify the production process of both, reduce production costs, and ensure the integrity and consistency of the structure.

[0064] In one embodiment, both the upper shielding shell 11 and the lower shielding shell 12 are integrally stamped from SUS304 thin sheet metal.

[0065] Both the upper shielding shell 11 and the lower shielding shell 12 are roughly rectangular in shape. Therefore, the upper shielding shell 11 includes a first long sidewall 111 and a second long sidewall 112 that are arranged opposite to each other, and the lower shielding shell 12 includes a third long sidewall 121 and a fourth long sidewall 122 that are arranged opposite to each other. The first long sidewall 111 and the fourth long sidewall 122 correspond to each other, and the second long sidewall 112 and the third long sidewall 121 correspond to each other, which facilitates the connection and fixation between them, realizing the assembly of the upper shielding shell 11 and the lower shielding shell 12. The two together form a board mounting space for mounting the PCB adapter board 20.

[0066] Furthermore, the upper shielding shell 11 can be slightly larger or slightly smaller than the lower shielding shell 12, and the heights of the first long sidewall 111, the second long sidewall 112, the third long sidewall 121, and the fourth long sidewall 122 can be the same or similar, so that the upper shielding shell 11 and the lower shielding shell 12 can be directly nested and fixed. In this way, the stability of the upper shielding shell 11 and the lower shielding shell 12 can be guaranteed when they are connected and fixed without the need for screws or other fasteners, thus reducing structural complexity, installation complexity, and structural cost.

[0067] In this embodiment, the first mounting groove 1111 and the second mounting groove 1121 are notches opened on the first long sidewall 111 and the second long sidewall 112, respectively. They extend along the length direction of the first long sidewall 111 and the length direction of the second long sidewall 112, and occupy a certain height of the first long sidewall 111 and the second long sidewall 112. They can be roughly rectangular to ensure a sufficiently large installation area.

[0068] Similarly, the third mounting groove 1211 and the fourth mounting groove 1221 are notches opened on the third long sidewall 121 and the fourth long sidewall 122, respectively. They extend along the length direction of the third long sidewall 121 and the length direction of the fourth long sidewall 122, and occupy a certain height of the third long sidewall 121 and the fourth long sidewall 122. They can be roughly rectangular to ensure a sufficiently large installation area.

[0069] Additionally, please combine Figures 1 to 3 The mounting ears 21 on both sides of the PCB adapter board 20 are respectively located near both ends of the board body. Therefore, the first mounting groove 1111 and the second mounting groove 1121 are located at different ends of the shielding upper shell 11, that is, they are respectively located near both ends of the shielding upper shell 11. Similarly, the third mounting groove 1211 and the fourth mounting groove 1221 are located at different ends of the shielding lower shell 12, that is, they are respectively located near both ends of the shielding lower shell 12. In this way, when the PCB adapter board 20 is installed on the shielding upper shell 11 and / or the shielding lower shell 12, both ends of the PCB adapter board 20 can be fixed, making the installation more stable and further improving the structural stability.

[0070] In this embodiment, the PCB adapter board 20 can be fixed in the upper shielding shell 11 and / or the lower shielding shell 12, specifically:

[0071] 1. When the PCB adapter board 20 is fixed in the shielding upper shell 11, a first mounting groove 1111 is provided on the first long side wall 111, and a second mounting groove 1121 is provided on the second long side wall 112. The fixing ears 21 on both sides of the PCB adapter board 20 are respectively engaged in the first mounting groove 1111 and the second mounting groove 1121, thereby fixing the PCB adapter board 20. Then, the shielding lower shell 12 is embedded into the shielding upper shell 11, or the shielding upper shell 11 is embedded into the shielding lower shell 12, to further press the PCB adapter board 20.

[0072] At this time, the first fixing port 13 is formed by the first mounting groove 1111, and the fourth long sidewall 122 can limit the fixing ear 21 that is engaged in the first mounting groove 1111, so that the fixing ear 21 can be pressed into the first mounting groove 1111 without obstructing the first fixing port 13 / first mounting groove 1111. The second fixing port 14 is formed by the second mounting groove 1121, and the third long sidewall 121 can limit the fixing ear 21 that is engaged in the second mounting groove 1121, so that the fixing ear 21 can be pressed into the second mounting groove 1121 without obstructing the second fixing port 14 / second mounting groove 1121.

[0073] 2. When the PCB adapter board 20 is fixed in the lower shielding shell 12, a third mounting groove 1211 is provided on the third long side wall 121, and a fourth mounting groove 1221 is provided on the fourth long side wall 122. The fixing ears 21 on both sides of the PCB adapter board 20 are respectively engaged in the third mounting groove 1211 and the fourth mounting groove 1221, thereby fixing the PCB adapter board 20. Then, the lower shielding shell 12 is embedded into the upper shielding shell 11, or the upper shielding shell 11 is embedded into the lower shielding shell 12, to further press the PCB adapter board 20.

[0074] At this time, the first fixing port 13 is formed by the fourth mounting groove 1221, and the first long sidewall 111 can limit the fixing ear 21 that is engaged in the fourth mounting groove 1221, so that the fixing ear 21 can be pressed into the fourth mounting groove 1221 without obstructing the first fixing port 13 / fourth mounting groove 1221. The second fixing port 14 is formed by the third mounting groove 1211, and the second long sidewall 112 can limit the fixing ear 21 that is engaged in the third mounting groove 1211, so that the fixing ear 21 can be pressed into the third mounting groove 1211 without obstructing the first fixing port 13 / third mounting groove 1211.

[0075] 3. When the PCB adapter board 20 is fixed to the upper shielding shell 11 or the lower shielding shell 12, a first mounting groove 1111 is provided on the first long sidewall 111, a second mounting groove 1121 is provided on the second long sidewall 112, a third mounting groove 1211 is provided on the third long sidewall 121, and a fourth mounting groove 1221 is provided on the fourth long sidewall 122. The fixing ears 21 on both sides of the PCB adapter board 20 can be first engaged with the first mounting groove 1111 and the second mounting groove 1121, or the third mounting groove 1211 and the fourth mounting groove 1221, to fix the PCB adapter board 20. Then, the lower shielding shell 12 is embedded into the upper shielding shell 11, or the upper shielding shell 11 is embedded into the lower shielding shell 12, to further compress the PCB adapter board 20.

[0076] At this time, the first fixing port 13 is composed of the first mounting groove 1111 and the fourth mounting groove 1221, and the second fixing port 14 is composed of the second mounting groove 1121 and the third mounting groove 1211. The first mounting groove 1111 and the fourth mounting groove 1221, along with the second mounting groove 1121 and the third mounting groove 1211, not only form a compact and effective limit for the two fixing ears 21, but also make the nesting between the upper shielding shell 11 and the lower shielding shell 12 tighter and deeper, which can further improve the stability when the upper shielding shell 11 and the lower shielding shell 12 are connected, and further reduce the volume of the PCB adapter board mounting box 10.

[0077] It is understandable that, since the PCB adapter board 20 also has components for signal transmission and conversion, and the shielding lower shell 12 is the part corresponding to the endoscope's related structures when the PCB adapter board mounting box 10 is installed on the endoscope, in actual implementation, the PCB adapter board 20 can be installed in the shielding lower shell 12, with the two fixing ears 21 respectively snapped into the third mounting slot 1211 and the fourth mounting slot 1221, and the components on the PCB adapter board 20 facing the shielding upper shell 11 (i.e., facing upwards).

[0078] Thus, when the shielding shell 11 is removed, the PCB adapter board 20 faces the operator, making it easier to perform maintenance, disassembly and other operations. This reduces the need to flip the shielding shell 11 to make the PCB adapter board 20 face the operator when installing it on the shielding shell 11.

[0079] exist Figure 4 In the illustrated embodiment, the first mounting slot 1111 and the fourth mounting slot 1221 constitute a first fixing port 13 for fixing one fixing ear 21, and the second mounting slot 1121 and the third mounting slot 1211 constitute a second fixing port 14 for fixing another fixing ear 21. The PCB adapter board 20 is mainly located in the lower shielding shell 12, with its front side (i.e. the side with components) facing the upper shielding shell 11. The PCB adapter board 20 is pressed against the lower shielding shell 12 by the upper shielding shell 11.

[0080] Please see Figures 1 to 4 Furthermore, the first long sidewall 111 is also provided with a fifth mounting groove 1112 spaced apart from the first mounting groove 1111; and / or

[0081] The fourth long sidewall 122 is also provided with a sixth mounting groove 1222 that is spaced apart from the fourth mounting groove 1221;

[0082] Among them, the fifth mounting slot 1112 and / or the sixth mounting slot 1222 correspond to the button interface on the PCB adapter board 20.

[0083] Specifically, the first mounting slot 1111 is located closer to the end of the upper shielding shell 11, the fifth mounting slot 1112 is located closer to the middle of the upper shielding shell 11, the fourth mounting slot 1221 is located closer to the end of the lower shielding shell 12, and the sixth mounting slot 1222 is located closer to the middle of the lower shielding shell 12. The structure of the fifth mounting slot 1112 and / or the sixth mounting slot 1222 is similar to that of the first mounting slot 1111 and / or the fourth mounting slot 1221. The fifth mounting slot 1112 and / or the sixth mounting slot 1222 can form an exposed opening for the button interface on the PCB adapter board 20 (the button interface is located on the back of the PCB adapter board 20), which facilitates the connection between the button interface and the corresponding trigger button.

[0084] In one embodiment, when the PCB adapter board 20 is disposed on the shielding upper shell 11, a fifth mounting groove 1112 can be provided only on the first long sidewall 111 to correspond to the button interface on the PCB adapter board 20, and the fourth long sidewall 122 will not cover the fifth mounting groove 1112.

[0085] In another embodiment, when the PCB adapter board 20 is disposed on the shielding lower shell 12, a sixth mounting slot 1222 can be provided only on the fourth long sidewall 122 to correspond to the button interface on the PCB adapter board 20, and the first long sidewall 111 will not cover the sixth mounting slot 1222.

[0086] In another embodiment, when the PCB adapter board 20 is disposed on the shielding upper shell 11 or the shielding lower shell 12, a fifth mounting groove 1112 is provided on the first long sidewall 111, and a sixth mounting groove 1222 is provided on the fourth long sidewall 122. Both the fifth mounting groove 1112 and the sixth mounting groove 1222 correspond to the button interface on the PCB adapter board 20. The first long sidewall 111 and the fourth long sidewall 122 will not structurally interfere with the PCB adapter board 20, thus promoting the nesting of the shielding upper shell 11 and the shielding lower shell 12.

[0087] Please see Figure 1 and Figure 4Furthermore, the inner side of the first long sidewall 111 is fitted with the outer side of the fourth long sidewall 122, and the inner side of the second long sidewall 112 is fitted with the outer side of the third long sidewall 121; or

[0088] The outer side of the first long sidewall 111 is attached to the inner side of the fourth long sidewall 122, and the outer side of the second long sidewall 112 is attached to the inner side of the third long sidewall 121.

[0089] It is understandable that the first long sidewall 111, the second long sidewall 112, the third long sidewall 121, and the fourth long sidewall 122 are long enough. By making the inner / outer side of the corresponding first long sidewall 111 fit with the outer / inner side of the fourth long sidewall 122, and the inner / outer side of the second long sidewall 112 fit with the outer / inner side of the third long sidewall 121, it is beneficial to the stable nesting of the upper shielding shell 11 and the lower shielding shell 12, and to ensure the structural stability and airtightness of the PCB adapter board 20 during installation.

[0090] If the inner side of the first long sidewall 111 is attached to the outer side of the fourth long sidewall 122, and the inner side of the second long sidewall 112 is attached to the outer side of the third long sidewall 121, then the lower shielding shell 12 is nested in the upper shielding shell 11; if the outer side of the first long sidewall 111 is attached to the inner side of the fourth long sidewall 122, and the outer side of the second long sidewall 112 is attached to the inner side of the third long sidewall 121, then the upper shielding shell 11 is nested in the lower shielding shell 12.

[0091] In this embodiment, the inner side of the first long sidewall 111 is attached to the outer side of the fourth long sidewall 122, and the inner side of the second long sidewall 112 is attached to the outer side of the third long sidewall 121. That is, the lower shielding shell 12 is nested in the upper shielding shell 11. This method will be used as the basic implementation in the following text.

[0092] Please see Figures 1 to 5 Furthermore, the shielding lower shell 12 also includes a first short end wall 123 and a second short end wall 124 disposed opposite to each other, and a third long side wall 121, the first short end wall 123, the fourth long side wall 122 and the second short end wall 124 forming a plate mounting space.

[0093] At least one first wire passage 1231 is provided on the first short end wall 123 and at least one second wire passage 1241 is provided on the second short end wall 124, and / or, the two ends of the shielding upper shell 11 are respectively provided with a third wire passage 1131 and a fourth wire passage 1141.

[0094] The first cable port 1231 and / or the third cable port 1131 constitute the first signal line port 15, and the second cable port 1241 and / or the fourth cable port 1141 constitute the second signal line port 16.

[0095] Specifically, the first short end wall 123 and the second short end wall 124 are located at both ends of the lower shielding shell 12, and the first wire passage 1231 and the second wire passage 1241 are notches provided on the first short end wall 123 and the second short end wall 124, respectively. The upper shielding shell 11 has partial end walls at both ends. The end wall corresponding to the first short end wall 123 has a third wire passage 1131, which is a notch provided on the end wall at that location. The fourth wire passage 1141 is a notch provided on the other end of the upper shielding shell 11.

[0096] By providing a first cable pass 1231 and a second cable pass 1241 on the first short end wall 123 and the second short end wall 124 respectively, and / or providing a third cable pass 1131 and a fourth cable pass 1141 on both ends of the shielding upper shell 11 respectively, the corresponding signal lines can pass through the first cable pass 1231 and / or the third cable pass 1131 (i.e., the first signal line pass 15), and the second cable pass 1241 and / or the fourth cable pass 1141 (i.e., the second signal line pass 16) respectively from both ends of the PCB adapter board mounting box 10 into the PCB adapter board mounting box 10 and connect to the signal interface on the PCB adapter board 20.

[0097] The third long sidewall 121, the first short endwall 123, the fourth long sidewall 122, and the second short endwall 124 are connected end to end to form a board mounting space for installing the PCB adapter board 20. That is, the PCB adapter board 20 is inserted into the lower shielding shell 12. At this time, the lower shielding shell 12 is nested in the upper shielding shell 11. That is, the inner side of the sidewall of the lower shielding shell 12 is connected and fits against the outer side of the upper shielding shell 11, so as to avoid the situation where the sidewall of the upper shielding shell 11 is inserted into the lower shielding shell 12 and is blocked by the PCB adapter board 20.

[0098] In addition, the outer sides of some end walls at both ends of the upper shielding shell 11 are also connected and fitted to the inner sides of the first short end wall 123 and the second short end wall 124 respectively, further improving the stability when the upper shielding shell 11 and the lower shielding shell 12 are nested and assembled.

[0099] In this embodiment, at least one first cable pass 1231 is provided on the first short end wall 123 and at least one second cable pass 1241 is provided on the second short end wall 124, and / or, a third cable pass 1131 and a fourth cable pass 1141 are respectively provided at both ends of the shielding upper shell 11, and the first cable pass 1231 and / or the third cable pass 1131 constitute a first signal line pass 15, and the second cable pass 1241 and / or the fourth cable pass 1141 constitute a second signal line pass 16, which can be understood as:

[0100] 1. When the PCB adapter board 20 is fixed in the shielding lower shell 12, the first wire passage 1231 can be provided only on the first short end wall 123, and the second wire passage 1241 can be provided on the second short end wall 124.

[0101] At this time, the first signal line port 15 is composed of the first cable port 1231, and the second signal line port 16 is composed of the second cable port 1241. The signal line passes through the first signal line port 15 and the second signal line port 16 at both ends of the shielded lower shell 12 and enters the PCB adapter board mounting box 10, and connects with the signal interface on the PCB adapter board 20.

[0102] 2. When the PCB adapter board 20 is fixed in the shielding upper shell 11, the third cable port 1131 and the fourth cable port 1141 can be provided only at both ends of the shielding upper shell 11.

[0103] At this time, the first signal line port 15 is formed by the third signal line port 1131, and the second signal line port 16 is formed by the fourth signal line port 1141. The signal line passes through the first signal line port 15 and the second signal line port 16 at both ends of the shielded upper shell 11 and enters the PCB adapter board mounting box 10, and connects with the signal interface on the PCB adapter board 20.

[0104] 3. When the PCB adapter board 20 is fixed in the lower shielding shell 12 or the upper shielding shell 11, a first wire passage 1231 is provided on the first short end wall 123, a second wire passage 1241 is provided on the second short end wall 124, and a third wire passage 1131 and a fourth wire passage 1141 are provided at both ends of the upper shielding shell 11.

[0105] At this time, the first signal line port 15 is formed by the first cable port 1231 and the third cable port 1131, and the second signal line port 16 is formed by the second cable port 1241 and the fourth cable port 1141. The signal line passes through the first signal line port 15 and the second signal line port 16 at both ends of the shielding upper shell 11 and the shielding lower shell 12 and enters the PCB adapter board mounting box 10, connecting with the signal interface on the PCB adapter board 20;

[0106] The first cable pass 1231, the third cable pass 1131, the second cable pass 1241, and the fourth cable pass 1141 not only allow signal lines to pass through without obstruction, but also make the nesting between the upper shield 11 and the lower shield 12 tighter and deeper, which can further improve the stability when the upper shield 11 and the lower shield 12 are connected, and further reduce the size of the PCB adapter board mounting box 10.

[0107] In this embodiment, the PCB adapter board 20 is fixed in the shielding lower shell 12. The first cable pass 1231 and the third cable pass 1131 constitute the first signal cable pass 15 for signal cables to pass through, and the second cable pass 1241 and the fourth cable pass 1141 constitute the second signal cable pass 16 for signal cables to pass through.

[0108] Please see Figures 1 to 4 Furthermore, a first fixing part 125 and a second fixing part 126 are respectively provided on the first short end wall 123 and the second short end wall 124, and a third fixing part 115 and a fourth fixing part 116 are respectively provided at both ends of the shielding upper shell 11, with the first fixing part 125 and the second fixing part 126 corresponding to the third fixing part 115 and the fourth fixing part 116 respectively.

[0109] Specifically, the first fixing part 125 and the second fixing part 126 are located at the edges of the first short end wall 123 and the second short end wall 124, respectively, and are in the form of thin plates extending outward. The third fixing part 115 and the fourth fixing part 116 are located at both ends of the bottom wall of the upper shielding shell 11, respectively, and extend outward. When the upper shielding shell 11 and the lower shielding shell 12 are nested, it can be ensured that the first fixing part 125 and the third fixing part 115 are correspondingly connected, and the second fixing part 126 and the fourth fixing part 116 are correspondingly connected.

[0110] In addition, the first fixing part 125, the second fixing part 126, the third fixing part 115 and the fourth fixing part 116 are all provided with through holes, and screws and other fasteners can be passed through the first fixing part 125, the third fixing part 115, the second fixing part 126 and the fourth fixing part 116 respectively to fix the two ends of the shielding upper shell 11 and the shielding lower shell 12 respectively. The fasteners can also install the PCB adapter board mounting box 10 at the corresponding position of the endoscope 1000, which facilitates the installation and removal of the PCB adapter board mounting box 10.

[0111] Please see Figures 1 to 4 Furthermore, there are two first wire passages 1231 and two third wire passages 1131. The first fixing part 125 is located between the two first wire passages 1231, and the third fixing part 115 is located between the two third wire passages 1131.

[0112] The second fixing part 126 is adjacent to the second wire passage 1241, and the fourth fixing part 116 is located at the opening of the fourth wire passage 1141 and avoids the second wire passage 1241.

[0113] Specifically, two first cable ports 1231 are located on both sides of the first fixing part 125, and two third cable ports 1131 are located on both sides of the third fixing part 115. The two first cable ports 1231 and the two third cable ports 1131 can accommodate two signal lines. The two signal lines are located on both sides of the first fixing part 125 and the third fixing part 115, and are spaced a certain distance apart from each other to avoid interference.

[0114] A second wire passage 1241 is provided on the second short end wall 124 of at least one side of the left and right sides of the second fixing part 126, and a fourth wire passage 1141 is provided on at least one side of the left and right sides of the fourth fixing part 116. The second fixing part 126 and the fourth fixing part 116 will not block the second wire passage 1241 and the fourth wire passage 1141, ensuring unobstructed passage of the signal line.

[0115] In this embodiment, there are also two second cable ports 1241 and four cable ports 1141. Of the two second signal cable ports 16 formed, one can be used to pass signal cables through, and the other can be a spare cable port for use when needed.

[0116] Please see Figures 1 to 3 Furthermore, a clearance opening 1132 is provided between the two third cable passage openings 1131, the third fixing part 115 corresponds to the clearance opening 1132, and the first fixing part 125 is engaged in the clearance opening 1132.

[0117] The fourth fixing part 116 is in the shape of a through groove, and the second fixing part 126 is embedded in the fourth fixing part 116.

[0118] It is understood that the first fixing part 125 is locked in the clearance opening 1132, and can be directly aligned with the third fixing part 115, making the alignment more accurate. Furthermore, the first fixing part 125 will be locked between the two third wire passages 1131, and the end walls of the two third wire passages 1131 can be used to limit the first fixing part 125, thereby improving the alignment stability of the first fixing part 125 and the third fixing part 115, and thus improving the assembly stability of the shielding upper shell 11 and the shielding lower shell 12 at one end of the PCB adapter board mounting box 10.

[0119] The fourth fixing part 116 is in the shape of a through groove, such as Figure 2 As shown, the fourth fixing part 116 has upwardly extending sidewalls on both sides, which can be used to accommodate the second fixing part 126 so that it can be embedded, thereby improving the stability of the alignment between the two and improving the assembly stability of the shielding upper shell 11 and the shielding lower shell 12 at the other end of the PCB adapter board mounting box 10.

[0120] Furthermore, the side wall of the fourth fixing part 116 can also form the fourth cable passage 1141 together with the bottom wall, side wall and part of the end wall of the shielding upper shell 11, providing a certain limiting effect for the passage of signal lines.

[0121] Please see Figures 5 to 8 The adapter board module 100 of this utility model embodiment includes:

[0122] PCB adapter board 20, with outwardly protruding fixing ears 21 on both sides; and

[0124] In the adapter board module 100 of this utility model embodiment, the upper shield 11 and the lower shield 12 are used as the mounting structure of the PCB adapter board 20, which can achieve better anti-interference and anti-radiation effects, and ensure that the normal function of the PCB adapter board 20 is not affected by interference and radiation.

[0125] Furthermore, since the PCB adapter board 20 is provided with fixing ears 21 on both sides, according to the actual structure of the PCB adapter board 20, a first mounting groove 1111 is provided on the first long sidewall 111 and a second mounting groove 1121 is provided on the second long sidewall 112, and / or a third mounting groove 1211 is provided on the third long sidewall 121 and a fourth mounting groove 1221 is provided on the fourth long sidewall 122. This makes the first mounting groove 1111 and / or the fourth mounting groove 1221 form a first fixing port 13 for fixing one fixing ear 21, and the second mounting groove 1121 and / or the third mounting groove 1211 form a second fixing port 14 for fixing another fixing ear 21. The structure of the PCB adapter board mounting box 10 is simple, and no additional fasteners or other installation structures are required to achieve stable installation of the PCB adapter board 20 in the PCB adapter board mounting box 10, further ensuring the stability of signal transmission and conversion.

[0126] Please see Figures 5 to 7 Furthermore, the PCB adapter board 20 is provided with a first signal interface 22, a second signal interface 23, a third signal interface 24, a first button interface 25, and a second button interface 26. The adapter board module 100 also includes a first signal line 30, a second signal line 40, a third signal line 50, a first trigger button 60, and a second trigger button 70, wherein:

[0127] The first signal line 30 and the second signal line 40 pass through one end of the PCB adapter board mounting box 10 and are connected to the first signal interface 22 and the second signal interface 23, respectively; the third signal line 50 passes through the other end of the PCB adapter board mounting box 10 and is connected to the third signal interface 24; the first trigger button 60 and the second trigger button 70 pass through the same side of the PCB adapter board mounting box 10 and are connected to the first button interface 25 and the second button interface 26, respectively.

[0128] The first signal interface 22 and the second signal interface 23 are located on the same end of the PCB adapter board 20 (e.g., Figure 6 (As shown on the left end), the first signal interface 22 can be a signal input, and the first signal line 30 can be an input signal line. Its two ends are respectively connected to the first signal interface 22 and the corresponding functional module to realize the signal input of the corresponding functional module to the PCB adapter board 20.

Its two ends are respectively connected to the second signal interface 23 and the endoscope host, so as to realize the signal output of the PCB adapter board 20 to the endoscope host.

[0130] The third signal interface 24 can be an image signal output, and the third signal line 50 can be an optical fiber line, with its two ends connected to the third signal interface 24 and the endoscope host respectively, to realize the image signal transmission between the PCB adapter board 20 and the endoscope host.

[0131] For example, the CMOS image signal is transmitted to the PCB adapter board 20 via the first signal line 30 and the first signal interface 22. The PCB adapter board 20 converts the CMOS image signal into a communication signal (such as a MIPI signal). On one hand, the PCB adapter board 20 transmits the CMOS image signal to the endoscope host via the third signal interface 24 and the third signal line 50, and the endoscope host converts it into an image for display. On the other hand, the communication signal is output to the endoscope host via the second signal interface 23 and the second signal line 40, and the endoscope host performs corresponding control.

[0132] In this embodiment, the first button interface 25 and the second button interface 26 are located on the same side of the PCB adapter board 20 (e.g., Figure 6 (as shown on the lower side) so as to facilitate connection with the first trigger button 60 and the second trigger button 70.

[0133] The first button interface 25 can be the first function interface, and the first trigger button 60 can be the first function button. Its two ends are respectively connected to the first function button and the endoscope host. After the first trigger button 60 is operated, the first function interface receives the trigger action and transmits the corresponding signal to the endoscope host through the second signal line 40. The endoscope host controls and triggers the first function of the endoscope 1000 (such as performing control operation).

[0134] The second button interface 26 can be a second function interface, and the second trigger button 70 can be a second function button. Its two ends are connected to the second function interface and the endoscope host respectively. After the second trigger button 70 is operated, the second function interface receives the trigger action and transmits the corresponding signal to the endoscope host through the second signal line 40. The endoscope host controls the triggering of the second function of the endoscope 1000 (such as image freeze).

[0135] In this embodiment, the first trigger button 60 and the second trigger button 70 can be flexible printed circuit (FPC) buttons, which are convenient for user operation.

[0138] Furthermore, since the PCB adapter board 20 is provided with fixing ears 21 on both sides, according to the actual structure of the PCB adapter board 20, a first mounting groove 1111 is provided on the first long sidewall 111 and a second mounting groove 1121 is provided on the second long sidewall 112, and / or a third mounting groove 1211 is provided on the third long sidewall 121 and a fourth mounting groove 1221 is provided on the fourth long sidewall 122. This makes the first mounting groove 1111 and / or the fourth mounting groove 1221 form a first fixing port 13 for fixing one fixing ear 21, and the second mounting groove 1121 and / or the third mounting groove 1211 form a second fixing port 14 for fixing another fixing ear 21. The structure of the PCB adapter board mounting box 10 is simple, and no additional fasteners or other installation structures are required to achieve stable installation of the PCB adapter board 20 in the PCB adapter board mounting box 10, further ensuring the stability of signal transmission and conversion.

[0139] In this embodiment, the adapter plate module 100 can be installed on the side of the endoscope 1000 using fasteners such as screws, so as to reduce the space occupied by the endoscope 1000.
