[0033] Based on the problem that existing endoscopes can only achieve electrostatic shielding of the imaging module but cannot avoid electrostatic interference in other locations, the present application provides an endoscope camera that can achieve comprehensive electrostatic shielding of the endoscope.

[0034] For details, please refer to Figures 1 to 6 The endoscope camera head includes a housing 11, an imaging module 12, a cable assembly 13, a first conductive seal 14, and a second conductive seal 15. A lens mounting port 112 is provided at the front end of the housing 11, and a cable mounting port 113 is provided at the rear end of the housing 11. The imaging module 12 is mounted on the lens mounting port 112 and the cable assembly 13 is mounted on the cable mounting port 113. The cable assembly 13 has a shielding layer. The first conductive seal 14 is interference-mounted on the lens mounting port 112 to connect the imaging module 12 and the housing 11 to form a first shielding path. The second conductive seal 15 is interference-mounted on the cable mounting port 113 to connect the cable assembly 13 and the housing 11 to form a second shielding path connected to the first shielding path, and the second shielding path is connected to the shielding layer.

[0035] It can be understood that the imaging module 12 is connected to the housing 11 through the first conductive seal 14, thereby forming a first shielding path, the cable is connected to the housing 11 through the second conductive seal 15, thereby forming a second shielding path, the first shielding path and the second shielding path are connected through the housing 11, and the second shielding path is connected to the shielding layer of the cable assembly 13. In this way, the electrostatic interference received by the endoscope on the imaging module 12, the housing 11 and the cable assembly 13 can be transmitted to the shielding layer of the cable assembly 13 through the first shielding path and the second shielding path, thereby avoiding the electrostatic interference from affecting the imaging effect of the endoscope. In addition, the first conductive seal 14 and the second conductive seal 15 can serve as both electrostatic shielding elements and sealing elements to ensure the sealing performance of the lens end and the cable end of the endoscope, so that the endoscope camera can simplify the structure of the endoscope.

[0036] Alternatively, if Figure 2 , Figure 3 and Figure 4 As shown, in one embodiment, the imaging module 12 includes a module body 121 and a first mounting groove 122 provided in the module body 121, and the first conductive seal 14 is installed in the first mounting groove 122. It is easier to process and assemble the first conductive seal 14 by arranging the first mounting groove 122 on the module body 121. When assembling the imaging module 12 and the housing 11, the first conductive seal 14 is first installed in the first mounting groove 122, and then the module body 121 is installed in the lens mounting port 112 of the housing 11.

[0037] Alternatively, if Figure 2 , Figure 3 and Figure 5 As shown, in one embodiment, the housing 11 includes a housing body 111 and a cable installation portion 114 protruding from the housing body 111, the cable installation opening 113 is opened in the cable installation portion 114, the cable assembly 13 includes a cable body 131 and a locking ring 132 sleeved on the cable body 131, one end of the cable body 131 is inserted into the cable installation opening 113, and the locking ring 132 cooperates with the cable installation portion 114 to lock the cable body 131 to the cable installation portion 114. By locking or unlocking the locking ring 132, the cable body 131 can be disassembled.

[0038] Preferably, if Figure 2 , Figure 3 and Figure 5As shown, in one embodiment, the cable body 131 includes an insertion section 1311 inserted into the cable installation port 113, and the second conductive seal 15 is disposed on the insertion section 1311 to compress the second conductive seal 15 when the locking ring 132 is locked.

[0039] Preferably, if Figure 2 , Figure 3 and Figure 5 As shown, in one embodiment, the cable body 131 includes a second mounting groove 1312 opened on the outer side of the insertion section 1311, and the second conductive seal 15 is installed in the second mounting groove 1312. It is easier to process and assemble the second conductive seal 15 by arranging the second mounting groove 1312 on the insertion section 1311. When assembling the cable assembly 13 and the housing 11, the second conductive seal 15 is first installed in the second mounting groove 1312, and then the insertion section 1311 of the cable body 131 is inserted into the cable installation port 113 of the housing 11, and finally the locking ring 132 is locked with the cable installation portion 114.

[0040] Preferably, if Figure 5 As shown, in one embodiment, the outer side of the cable installation portion 114 is provided with an external thread, and the inner side of the locking ring 132 is provided with an internal thread that matches the external thread. By rotating the locking ring 132 forward or reverse, locking or unlocking can be achieved.

[0041] Alternatively, if Figure 6 As shown, in one embodiment, the first conductive seal 14 and the second conductive seal 15 are O-shaped conductive seal rings. The O-shaped conductive seal ring can seal the lens installation port 112 and the cable installation port 113, and the O-shaped conductive seal ring has conductive properties and can connect the first shielding path and the second shielding path.

[0042] Preferably, in one embodiment, the material of the first conductive seal 14 and the material of the second conductive seal 15 are conductive rubber materials. The conductive rubber materials can be carbon nickel rubber, silver nickel rubber and other elastic conductive rubber materials that can be used for manufacturing sealing elements.

[0043] It is worth noting that the contact surfaces of the first conductive seal 14 and the second conductive seal with the imaging module 12, the housing 11 and the cable assembly 13 are all exposed, so as to ensure that the imaging module 12, the housing 11 and the cable assembly 13 form a complete first shielding path and a second shielding path.

[0044] Furthermore, if Figure 1 and Figure 2As shown, in one embodiment, the endoscope camera head further includes a button assembly 16, an endoscope support 17 and a conductive fixing member 18, a button installation port 115 is provided on the side of the housing 11, the endoscope support 17 is fixed in the housing 11, the button assembly 16 is installed in the button installation port 115, and the conductive fixing member 18 fixes the button assembly 16 to the endoscope support 17 to connect the button assembly 16 and the endoscope support 17, thereby forming a third shielding path connected to the first shielding path and the second shielding path. In this way, the button assembly 16 and the endoscope support 17 are connected through the conductive fixing member 18 to form the third shielding path, and the endoscope support 17 is connected to the housing 11, so that the third shielding path is connected to the first shielding path and the second shielding path, thereby realizing a more comprehensive electrostatic shielding full path, so that the electrostatic interference to the button assembly 16 can also be transmitted to the shielding layer of the cable assembly 13.

[0045] It is worth noting that the button assembly 16 can be a silicone member. Since the silicone member itself has elasticity, the button assembly 16 can seal the button installation port 115, thereby improving the sealing performance of the endoscope.

[0046] Optionally, in one embodiment, the endoscope support 17 is provided with a threaded hole, the button assembly 16 is provided with a through hole, and the conductive fixing member 18 is a bolt, which passes through the through hole and is screwed with the threaded hole to fix the button assembly 16. The bolt can connect the button assembly 16 and the endoscope support 17 to form the third shielding path.

[0047] The technical features of the above embodiment can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above embodiment are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The above embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
