[0031] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application.

[0032] In order to deepen the understanding of this application solution, it is necessary to elaborate on the technical issues in detail in combination with relevant technologies. The specific contents are as follows:

[0033] At present, the filter sockets of most endoscope products are connected to the chassis only through a plug-in, and the structure is easy to loosen, affecting the plug-in and unplug experience of the filter. In addition, the main metal part of the filter socket is generally in direct contact with the chassis. After the filter is electrically plugged into the filter socket, the filter and the chassis are indirectly electrically contacted, which causes the static charge on the chassis to easily cause electromagnetic interference to the filter, and the structure's ability to resist electromagnetic interference becomes poor, which may affect the normal use of the filter.

[0034] Further, refer to Figure 1 , Figure 2 and Figure 5 The upper and lower parts of the filter socket 300 are provided with raised metal springs 340, the front end of the filter socket 300 is provided with a limiting annular step 330, and the side wall of the chassis 100 is provided with a socket 110, and the edge of the socket 110 is clamped between the metal spring 340 and the limiting annular step 330 to complete the fixing of the filter socket 300. The filter socket 300 is clamped with the socket 110 of the chassis 100, and the whole is easy to loosen, which affects the plug-in experience of the filter, and the filter socket 300 is not easy to disassemble and assemble, which increases the difficulty of assembly or maintenance. The metal spring 340 of the filter socket 300 is in direct contact with the chassis 100. After the filter is electrically plugged into the filter socket 300, the filter is indirectly electrically contacted with the chassis 100, which causes the electrostatic charge on the chassis 100 to easily cause electromagnetic interference to the filter, and the anti-electromagnetic interference ability of the structure is deteriorated, which may affect the normal use of the filter.

[0035] In order to alleviate the above technical problems, the present application provides a floating structure of an endoscope camera system filter. Figures 3 to 7 The embodiments of the present application are described in detail.

[0036] First, refer to Figure 4The floating structure of the filter of the endoscope camera system provided in the present application includes a chassis 100, an insulating component 200 and a filter socket 300. Among them, a jack 110 is provided on the side wall of the chassis 100. The insulating component 200 is fixed inside the chassis 100, and a mounting cavity is provided inside the insulating component 200. The filter socket 300 is provided in the mounting cavity, and a slot 310 is provided at the front end of the filter socket 300, and the slot 310 corresponds to the jack 110.

[0037] It should be noted that, refer to Figure 1 , Figure 3 and Figure 5 In this application, the end of the chassis 100 with the jack 110 is the front end, and the other end opposite to the front end is the rear end; correspondingly, the end of the filter socket with the slot 310 is the front end, and the other end opposite to the front end is the rear end. In addition, the thickness direction of the chassis is the up-down direction.

[0038] Specifically, in this solution, the insulating component 200 is fixed inside the chassis 100, and the insulating component 200 separates the main metal part of the filter socket 300 from the chassis 100, so that the filter socket 300 and the chassis 100 are prevented from electrical contact, and then after the filter is electrically plugged into the filter socket 300, the filter also avoids electrical contact with the chassis 100, reducing the risk of electrostatic charge on the chassis 100 to interfere with the filter electromagnetically, improving the product qualification rate, and further ensuring the normal use of the filter; in addition, the insulating component 200 wraps the filter socket 300, the connection is firm and not easy to loosen, so that the filter has a good user experience when plugging and unplugging the filter and the filter socket 300; in addition, the filter socket 300 does not need to protrude from the outside of the chassis 100 due to the card connection with the jack 110. The filter socket 300 is stored in the chassis 100 through the insulating component 200, and the overall space occupied is small, avoiding interference with external components.

[0039] It should be noted that the filter is a frequency selection device that can effectively filter out a specific frequency point in the power line or frequencies other than this frequency point to obtain a power signal of a specific frequency, or eliminate a power signal after eliminating a specific frequency. It is an important functional component in the endoscope camera system.

[0040] In addition, the floating ground structure is explained: First, the ground is defined as an equipotential point or plane that is the reference of a circuit or system. "Ground" in the field of electronic equipment usually refers to "the earth." In practice, "grounding" generally refers to connecting the housing of the device to the earth, using the earth as the grounding reference point of the device. "Floating ground" means that the target circuit is connected to the earth without a conductor. The advantage is that the circuit is not affected by the electrical properties of the earth and has a certain ability to resist electromagnetic interference. In this solution, the filter socket 300 is separated from the chassis 100 by an insulating component 200. When the filter is electrically plugged into the filter socket 300, a floating ground structure is formed to avoid electromagnetic interference, further ensuring that the filter can be used normally after being electrically plugged into the filter socket 300.

[0041] In some embodiments, reference Figure 3 The insulating assembly 200 includes a first cover body 210 and a second cover body 220 that are interlocked and detachably connected, and an installation cavity is formed between the first cover body 210 and the second cover body 220.

[0042] Specifically, in some embodiments, the first cover body 210 and the second cover body 220 are interlocked to form an installation space therebetween. Compared with the first cover body 210 and the second cover body 220 being integrally formed, this embodiment is more convenient for assembling and disassembling the filter socket 300, which helps to save the assembly and maintenance costs of the filter socket 300.

[0043] In particular, the first cover body 210 and the second cover body 220 can be arranged correspondingly up and down, or can be arranged correspondingly left and right, or can be arranged diagonally, all of which can achieve the purpose of forming an installation space inside after being buckled together. The above schemes all fall within the protection scope of this application.

[0044] In some embodiments, reference Figure 3 The first cover 210 is detachably connected to the bottom wall of the chassis 100 via a first fastener 230 , and the second cover 220 is detachably connected to the top of the first cover 210 via a second fastener 240 .

[0045] Specifically, in some embodiments, the first cover body 210 is connected to the bottom wall of the chassis 100 through the first fastener 230, and the connection is firm. The first cover body 210 and the second cover body 220 are buckled together and connected through the second fastener 240. This makes it easy to disassemble and assemble the filter socket 300 above the chassis 100 after removing the top cover of the chassis 100. The operation is simple and practical.

[0046] In some embodiments, reference Figure 3 , Figure 6 and Figure 7The first cover body 210 includes a bottom plate 211 and a plurality of first connecting columns 212 extending upward from the bottom plate 211; the second cover body 220 includes a top plate 221 and a plurality of second connecting columns 222 extending downward from the top plate 221; when the first cover body 210 and the second cover body 220 are buckled together, the plurality of first connecting columns 212 and the plurality of second connecting columns 222 are staggered with each other.

[0047] In some embodiments, there are four first connecting columns 212, which are evenly divided into two groups, and the two groups of first connecting columns 212 are respectively distributed on the two side edges of the bottom plate 211; similarly, there are four second connecting columns 222, which are also evenly divided into two groups, and the two groups of second connecting columns are respectively distributed on the two side edges of the top plate 221.

[0048] In some embodiments, reference Figure 3 , Figure 6 and Figure 7 A plurality of first mounting holes 213 are formed on the bottom plate 211, and a plurality of first fasteners 230 are respectively penetrated through the first mounting holes 213 and locked to the bottom wall of the chassis 100; a connecting hole 214 is formed from the top of the first connecting column 212 and extends along the length direction of the main body and penetrates the main body; an outward folding plate 223 is formed at the bottom of the second connecting column 222, and a plurality of second mounting holes 224 are formed on the outward folding plate 223, and a plurality of second fasteners 240 are respectively penetrated through the second mounting holes 224 and locked to the connecting holes 214.

[0049] Specifically, this solution further discloses the specific connection method of the first cover body 210, the second cover body 220 and the chassis 100, and has a reasonable structure and a reliable connection.

[0050] More specifically, there are two outward folding plates 223, and the two outward folding plates 223 correspond to the first connecting columns 212 on both sides of the bottom plate 211 respectively; in addition, in some embodiments, the first fastener 230 and the second fastener 240 are bolts or screws, and the connecting hole 214 is a screw hole.

[0051] In some embodiments, reference Figure 3 , Figure 6 and Figure 7 A positioning block 215 protruding upward is provided at the top of the first connecting column 212 , and a positioning groove 225 is provided on the outward folding plate 223 , and the positioning groove 225 matches the positioning block 215 .

[0052] Specifically, in this solution, the positioning groove 225 matches the positioning block 215, so that the first cover body 210 and the second cover body 220 are more accurately positioned when they are buckled together, and before the second fastener 240 is locked, the two can also limit each other.

[0053] In particular, a positioning block 215 is provided on the outward folding plate 223, and a positioning groove 225 is provided on the first connecting column 212, which is a simple transformation of the present solution and also falls within the protection scope of the present application.

[0054] In some embodiments, reference Figure 7 A plurality of avoidance notches 226 are provided on the top plate 221 , and the avoidance notches 226 correspond to the second mounting holes 224 .

[0055] Specifically, the avoidance notch 226 in this solution enables the second fastener 240 to be tightened or loosened by a tool above the chassis 100 when the top cover of the chassis 100 is removed, thereby facilitating the disassembly and assembly of the filter socket 300 .

[0056] In some embodiments, reference Figure 4 and Figure 5 A slot 310 is provided at the front end of the filter socket 300, and a plug 320 is provided at the rear end of the filter socket 300. The slot 310 is suitable for electrically plugging into the filter, and the plug 320 is suitable for electrically plugging into the power supply module in the chassis 100; a limiting annular step 330 is provided at the front end of the filter socket 300, and the limiting annular step 330 abuts against the inner wall of the edge of the socket 110 of the chassis 100.

[0057] Specifically, this solution describes the structure of the filter socket 300 , the front end of the filter socket 300 abuts against the chassis 100 through the limiting annular step 330 , does not protrude outside the socket 110 of the chassis 100 , and occupies little space.

[0058] It should be noted that the limiting annular step 330 is made of non-conductive material, so the direct contact between the limiting annular step 330 and the chassis 100 does not destroy the anti-electromagnetic interference effect of the floating structure, and at the same time can increase the stability of the overall structure.

[0059] In some embodiments, reference Figures 4 to 7 A first limiting edge 216 extending upward is provided on the bottom plate 211, and a first plug avoidance gap 217 is opened on the first limiting edge 216. The first limiting edge 216 is covered on the rear end of the filter socket 300, and the first plug avoidance gap 217 avoids the plug 320; a second limiting edge 227 extending downward is provided on the top plate 221, and a second plug avoidance gap 228 is opened on the second limiting edge 227. The second limiting edge 227 is covered on the rear end of the filter socket 300, and the second plug avoidance gap 228 avoids the plug 320.

[0060] Specifically, in this solution, the first limiting edge 216 and the second limiting edge 227 wrap the rear end of the filter socket 300, firmly connect, increase the covering area, and enhance the ability to resist electromagnetic interference; in addition, the first socket avoidance gap 226 and the second plug avoidance gap 228 avoid the plug 320 of the filter socket 300, and the structure is reasonable.

[0061] It should be noted that the first cover 210 and the second cover 220 mainly cover the middle and rear end of the filter socket 300 but do not cover the front end of the filter socket 300 , thereby avoiding the raised metal spring 340 , the limiting annular step 330 and the slot 310 .

[0062] In some embodiments, reference Figure 4 The insulating component 200 is a flexible structure, and the filter socket 300 is plugged into the installation cavity.

[0063] Specifically, the insulating component 200 is made of a soft material, and the filter socket 300 is inserted into the installation cavity, so that the connection between the filter socket 300 and the insulating component 200 is more firm, the fit is tighter, and the covering effect is good; more specifically, the top surface of the filter socket 300 fits with the top plate 221, its bottom surface fits with the bottom plate 211, its rear end surface fits with the first limiting edge 216 and the second limiting edge 227, and its front end surface fits with the inner wall of the edge of the socket 110 of the chassis 100.

[0064] In some embodiments, the first cover 210 and the second cover 220 are plastic parts.

[0065] In addition, the floating structure of the filter of the endoscope camera system of the present solution also includes other components, and only the components related to the present solution are listed here, but it does not limit the structure of the floating structure of the filter of the endoscope camera system.

[0066] Although the embodiments of the present application are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present application, and such modifications and variations are all within the scope defined by the appended claims.
