DETAILED DESCRIPTION

[0023] The following description provides many different embodiments or examples for implementing different features of the present invention. The components and arrangements described in the following specific examples are only used to simplify the present invention and are only examples, not to limit the present invention.

[0024] The embodiment of the present application provides a connector mounting structure, which is applied to an endoscope. The mounting structure includes a handle housing 200 of the endoscope and a connector adapter shell 100. Figures 1 to 8 As shown. The handle housing 200 is used by the operator to hold and facilitate operation of the endoscope. The adapter housing 100 is the outer shell of the connector, and the connector terminal module 500 is installed inside the adapter housing 100. When the connector is connected to the corresponding connector 710, the corresponding connector 710 is inserted into the adapter housing 100 and connects with the terminal module 500 inside the adapter housing 100, completing the docking of the corresponding connector 710 with the connector.

[0025] refer to Figure 1 As shown, the handle housing 200 of the endoscope includes two parts, a first housing 210 and a second housing 220, which are butt-jointed and assembled to form the handle housing 200. In addition, during the butt-jointed assembly process of the first housing 210 and the second housing 220, the adapter shell 100 can be pressed and fixed between the first housing 210 and the second housing 220, thereby fixing the adapter shell 100 in the handle housing 200.

[0026] The handle shell 200 is divided into two parts, a first shell 210 and a second shell 220, which is convenient for installing multiple components in the endoscope handle. After the components in the handle are installed, the first shell 210 and the second shell 220 are docked and assembled together to complete the assembly of the handle.

[0027] In the prior art, the installation process of the adapter shell 100 includes: placing the adapter shell 100 at a preset position in the first shell 210 or the second shell 220, and then using glue or other fixing methods to fix the position of the adapter shell 100 and its corresponding shell. After the other components in the handle are installed, the first shell 210 and the second shell 220 are docked to complete the assembly of the handle.

[0028] Compared with the prior art, the embodiment of the present application directly places the adapter shell 100 at a preset position in the first shell 210 or the second shell 220. During the subsequent docking process of the first shell 210 and the second shell 220, the installation of the adapter shell 100 can be completed, and the adapter shell 100 can be fixed in the handle shell 200, saving the steps of gluing or other fixing methods on the adapter shell 100, thereby improving the assembly efficiency of the adapter shell 100.

[0029] refer to Figure 2 As shown, during the installation of the adapter shell 100 , it is necessary to first place the adapter shell 100 at a preset position in the first shell 210 or the second shell 220 , and then assemble the other shell to complete the assembly of the adapter shell 100 .

[0030] Moreover, in the embodiment provided by the present application, when the connector and the handle housing 200 are assembled, the adapter shell 100 of the connector is in contact with the handle housing 200, and the terminal module 500 of the connector is installed inside the adapter shell 100. The terminal module 500 is protected by the adapter shell 100, which can avoid damage to the terminal module 500 during the assembly process of the connector.

[0031] refer to Figure 1 and Figure 2 As shown, the adapter shell 100 has an insertion port 130, and the insertion port 130 of the adapter shell 100 is used to plug and mate with the corresponding connector 710. The corresponding connector 710 is inserted into the insertion port 130 and connected to the terminal module 500 inside the adapter shell 100. Figure 1 As shown, the handle housing 200 has a docking port 230 , which connects the interior of the handle housing 200 with the external environment. The docking port 230 is used for the corresponding connector 710 to pass through, so that the corresponding connector 710 can be plugged into the connector in the handle housing 200 .

[0032] In the embodiment provided in the present application, when the adapter shell 100 is fixed in the handle shell 200, the plug-in interface 130 of the adapter shell 100 and the docking interface 230 of the handle shell 200 are correspondingly connected to expose the plug-in interface 130 of the adapter shell 100 to the external environment, thereby facilitating docking with the corresponding connector 710.

[0033] The connector inside the handle housing 200 can be a female connector, and the corresponding connector 710 that cooperates with the connector is a male connector; the connector inside the handle housing 200 can also be a male connector, and the corresponding connector 710 that cooperates with the connector is a female connector.

[0034] The adapter shell 100 is inside the handle shell 200 and is pressed and fixed by the first shell 210 and the second shell 220. In some embodiments of the present application, the assembly direction of the first shell 210 and the second shell 220 is set as the first direction. Figures 2 to 8 The z-axis direction is shown. When the adapter housing 100 is installed in the handle housing 200, the adapter housing 100 is limited in position with the handle housing 200 in the first direction. In the first direction, the two ends of the adapter housing 100 are the first housing 210 and the second housing 220, which are limited in position with the adapter housing 100 to limit the position of the adapter housing 100 in the first direction.

[0035] The outer surface of the adapter shell 100 is provided with at least one first positioning member, and the inner wall of the handle shell 200 is provided with at least one second positioning member. When the adapter shell 100 is assembled into the handle shell 200, the first positioning member and the second positioning member are limitedly matched, so that the adapter shell 100 is limitedly matched with the handle shell 200 in the second direction and the third direction. The second direction and the third direction are both arranged perpendicular to the first direction, wherein the second direction is the plugging direction of the connector and the corresponding connector 710. During the process of plugging and unplugging the corresponding connector 710 and the handle, the position of the connector can remain stable in the handle shell 200 to avoid accidental movement of the connector, which may cause unstable plugging with the corresponding connector 710. The third direction is arranged to intersect with the second direction. Reference Figures 2 to 8 As shown, the second direction is the y-axis direction shown in the figure, and the third direction is the x-axis direction shown in the figure.

[0036] It should be explained that, in the embodiment of the present application, the adapter shell 100 is limited in the first direction with the handle housing 200, which means that the handle housing 200 can limit the adapter shell 100 in the forward or reverse movement along the first direction. The position of the adapter shell 100 relative to the handle housing 200 in the first direction is fixed, and the adapter shell 100 cannot move in the first direction relative to the handle housing 200. The same applies to the second and third directions. The first, second and third directions are intersected, and the adapter shell 100 is limited in these three directions with the handle housing 200, and the adapter shell 100 is fixed in the handle housing 200.

[0037] The first positioning member and the second positioning member cooperate to locate the assembly position of the adapter shell 100 when the adapter shell 100 is initially assembled to the first shell 210 or the second shell 220, so that the adapter shell 100 can be accurately assembled to the preset position. In addition, the first positioning member and the second positioning member cooperate to form a limit between the adapter shell 100 and the handle shell 200. The second positioning member contacts the first positioning member, and the two mutually limit each other. At the same time, the second positioning member can also contact and cooperate with the adapter shell 100 provided with the first positioning member, thereby forming a limit between the adapter shell 100 and the handle shell 200 provided with the second positioning member.

[0038] The second direction is the direction of insertion between the connector and the corresponding connector 710. During the insertion and removal of the two connectors, the force applied to the contact portion of the adapter shell 100 and the handle housing 200 is parallel to the second direction, preventing the adapter shell 100 from shifting. The second direction is perpendicular to the first direction. During the insertion and removal of the connectors, the force applied to the contact portion of the adapter shell 100 and the handle housing 200 in the first direction is avoided, thereby ensuring the stability of the adapter shell 100 within the handle housing 200 to a certain extent.

[0039] In some embodiments of the present application, the adapter shell 100 is a closed structure along its circumference. The circumference of the adapter shell 100 refers to the direction around its plug-in port 130. The closed structure means that, in the circumference of the adapter shell 100, the adapter shell 100 is connected end to end without any gaps. The adapter shell 100 is a closed structure, and the overall strength of the adapter shell 100 is stronger. When it is limited with the handle shell 200 and plugged in and out with the corresponding connector 710, the adapter shell 100 is not prone to deformation, etc., and the protection effect on the terminal module 500 is better, and the overall structure of the connector is more stable.

[0040] In other embodiments of the present application, the adapter shell 100 may also be an open structure along its circumference. The open structure means that there is a notch in the adapter shell 100 in the circumference of the adapter shell 100. The adapter shell 100 is an open structure. Under the action of external force, the notch can be expanded or shrunk, thereby changing the overall size of the adapter shell 100. When the adapter shell 100 is plugged into the corresponding connector 710, the adapter shell 100 can adaptively deform to accommodate the corresponding connector 710, thereby reducing the difficulty of plugging and unplugging the corresponding connector 710. At the same time, the outside of the adapter shell 100 is limited by the handle shell 200, which limits the deformation of the adapter shell 100 within a certain range, thereby ensuring the tightness of the connection between the adapter shell 100 and the corresponding connector 710.

[0041] refer to Figures 3 to 8As shown, in some embodiments of the present application, the distal end of the adapter housing 100 is further provided with an extension 110. The extension 110 extends toward the distal end of the handle housing 200 and is positioned opposite the terminal module 500 connected to the adapter housing 100, thereby forming a first glue storage space 610 between the extension 110 and the terminal module 500. The first glue storage space 610 is used to store glue and secure the terminal module 500 to the extension 110. The extension 110 extends toward the distal end of the handle, thereby increasing the area where the extension 110 and the terminal module 500 are positioned relative to each other, thereby increasing the capacity of the first glue storage space 610 and improving the stability of the connection between the terminal module 500 and the adapter housing 100. Furthermore, the extension 110 is located only on one side of the terminal module 500, providing a foolproofing feature. When placing the adapter housing 100 into the first housing 210 or the second housing 220, the position of the extension 110 can be used to determine the placement direction of the adapter housing 100.

[0042] In some preferred embodiments, the extension portion 110 is further provided with a reinforcement protrusion 120 protruding toward the terminal module 500. Figure 4 and Figure 6 The reinforcing protrusion 120 is located within the first glue storage space 610, further increasing the contact area between the extension portion 110 and the glue, and further improving the stability of the connection between the extension portion 110 and the terminal module 500. Furthermore, the reinforcing protrusion 120 can enhance the overall structural strength of the extension portion 110, and when the extension portion 110 abuts the handle housing 200, the extension portion 110 is less likely to deform.

[0043] In some preferred embodiments of this application, reference is made to Figure 6 As shown, the first positioning member includes a first sub-positioning member 310, and the first sub-positioning member 310 is located on the surface of the extension portion 110 away from the first glue storage space 610, and the second positioning member includes a second sub-positioning member 410. When the adapter shell 100 is installed in the handle shell 200, the second sub-positioning member 410 is located on the side of the extension portion 110 away from the glue storage space, and the second sub-positioning member 410 is used to engage with the first sub-positioning member 310 so that the second sub-positioning member 410 and the first sub-positioning member 310 are engaged in the second direction.

[0044] The first sub-positioning member 310 is disposed on the surface of the extension portion 110, which facilitates the assembler to determine the assembly position of the extension portion 110. In addition, the extension portion 110 and the terminal module 500 are glued and fixed, and the overall structural strength is high. The first sub-positioning member 310 is disposed on the extension portion 110 to reduce the impact of the clamping and pulling between the first sub-positioning member 310 and the second sub-positioning member 410 on the structure of the extension portion 110, thereby reducing the probability of deformation or damage to the extension portion 110. In addition, further, when the first sub-positioning member 310 and the second sub-positioning member 410 are clamped together, the second sub-positioning member 410 can be attached to the surface of the extension portion 110, limiting the movement of the extension portion 110 toward the position of the second sub-positioning member 410, thereby limiting the position of the extension portion 110 in the third direction.

[0045] A reinforcing rib 411 may be connected between the second sub-positioning member 410 and the inner wall of the handle housing 200 to improve the connection stability between the handle housing 200 and the second sub-positioning member 410 .

[0046] In some embodiments of this application, reference Figures 3 to 8 , the first positioning member also includes a third sub-positioning member 320, and the third sub-positioning member 320 is located at the distal end of the adapter shell 100, and a second glue storage space 620 is formed between the third sub-positioning member 320 and the terminal module 500 connected to the adapter shell 100. The second glue storage space 620 is used to store glue to increase the connection stability between the terminal module 500 and the adapter shell 100. The second positioning member also includes a fourth sub-positioning member 420. When the adapter shell 100 is installed in the handle, the fourth sub-positioning member 420 is located on the side of the third sub-positioning member 320 away from the second glue storage space 620, and the fourth sub-positioning member 420 cooperates with the third sub-positioning member 320 in the third direction upper limit.

[0047] After the glue in the second glue storage space 620 solidifies, the terminal module 500 contacts the inner wall of the handle through the glue solidified in the second glue storage space 620, the third sub-positioning member 320 and the fourth sub-positioning member 420 in sequence, fully stabilizing the position of the terminal module 500 and ensuring that even during the plugging and unplugging process of the adapter shell 100 and the corresponding connector 710, even under the pulling action of the corresponding connector 710, the position of the terminal module 500 is not easily displaced.

[0048] Further preferably, the extension portion 110 and the third sub-positioning member 320 are respectively located on both sides of the terminal module 500 connected to the adapter shell 100, and correspondingly, the first glue storage space 610 and the second glue storage space 620 are respectively located on both sides of the terminal module 500, which can be referred to Figure 6 As shown, both sides of the terminal module 500 are fixed, and the connection between the terminal module 500 and the adapter housing 100 is more stable.

[0049] Furthermore, in some embodiments, in the third direction, the third sub-positioning member 320 is disposed closer to the inner wall of the handle relative to the extension portion 110. In addition to the connector, other components need to be installed in the handle housing 200 of the endoscope. Generally, the connector will not be located in the middle of the handle housing 200, but will be offset relative to the axis of the handle housing 200. Figure 7 As shown. One side of the adapter shell 100 is close to the inner wall of the handle shell 200, and the other side is close to the middle position of the handle shell 200. Compared with the extension part 110, the connection stability between the third sub-positioning member 320 and the terminal module 500 is weaker, so the third sub-positioning member 320 is set closer to the edge of the handle shell 200, and the fourth sub-positioning member 420 can be set on the inner wall of the handle shell 200. The handle shell 200 supports the fourth sub-positioning member 420 in the third direction, thereby improving the support effect on the terminal module 500. The edge of the handle shell 200 refers to the opening edge of the first shell 210 or the second shell 220.

[0050] In some embodiments, in the second direction, the length of the extension 110 is greater than the length of the third sub-positioning member 320. The size difference between the extension 110 and the third sub-positioning member 320 makes it easier for assemblers to determine the orientation of the adapter case 100, thereby accurately inserting the adapter case 100 into the handle housing 200.

[0051] refer to Figure 4 As shown, the third sub-positioning member 320 is arranged on the distal end face of the adapter shell 100. When the fourth sub-positioning member 420 contacts the third sub-positioning member 320, the fourth sub-positioning member 420 can also contact and cooperate with the distal end face of the adapter shell 100, thereby limiting cooperation with the adapter shell 100 in the second direction.

[0052] The first positioning member also includes a fifth sub-positioning member 330 and a seventh sub-positioning member 340. The fifth sub-positioning member 330 and the seventh sub-positioning member 340 are respectively located on both sides of the adapter case 100. The width of the fifth sub-positioning member 330 is different from the width of the seventh sub-positioning member 340, which facilitates the assembler to distinguish the orientation of the adapter case 100. The second positioning member includes a sixth sub-positioning member 430 and an eighth sub-positioning member 440 corresponding to the fifth sub-positioning member 330 and the seventh sub-positioning member 340.

[0053] refer to Figure 7 and Figure 8 As shown, when the adapter shell 100 is installed inside the handle, the fifth sub-positioning member 330 is engaged with the sixth sub-positioning member 430, and the seventh sub-positioning member 340 is engaged with the eighth sub-positioning member 440, so that the adapter shell 100 and the handle shell 200 are matched in the second direction and the third direction.

[0054] The snap connection can be that one of the positioning members forms a space for the other positioning member to be inserted, or one of the positioning members cooperates with the handle housing 200 to form a space for the other positioning member to be inserted. After the two positioning members cooperate with each other, they can form a limit in the second direction and / or the third direction to prevent the adapter housing 100 from moving.

[0055] Furthermore, in the third direction, the fifth sub-locator 330 is positioned away from the inner wall of the handle relative to the seventh sub-locator 340, and is closer to the middle portion of the handle housing 200. The sixth sub-locator 430, corresponding to the fifth sub-locator 330, is configured as a covering structure. The sixth sub-locator 430 covers the fifth sub-locator 330, thereby enhancing the positioning and support effect of the fifth sub-locator 330, thereby limiting and cooperating with the fifth sub-locator 330 in both the second and third directions. The sixth sub-locator 430 can be positioned near the proximal end of the handle housing 200 and fixed to the proximal portion of the handle housing 200, thereby improving the positioning stability of the sixth sub-locator 430.

[0056] Among the multiple sub-positioning members of the second positioning member provided in the embodiment of the present application, the multiple sub-positioning members can also be divided into two groups, one group is arranged on the inner wall of the first shell 210, and the other group is arranged on the inner wall of the second shell 220. In some preferred embodiments, the multiple sub-positioning members can be arranged on the inner wall of the first shell 210 or the second shell 220, and the adapter case 100 is first placed in the shell provided with the second positioning member, so as to facilitate the positioning and cooperation between the first positioning member provided on the outer surface of the adapter case 100 and the second positioning member in the handle shell 200.

[0057] An embodiment of the present application also provides an endoscope handle, comprising a terminal module 500 and a mounting structure of the connector provided in any of the above embodiments, wherein the terminal module 500 is mounted inside the adapter shell 100 .

[0058] The embodiment of the present application also provides an endoscope, including the endoscope handle provided in the above embodiment. When the endoscope is in use, a connecting line 700 is used to connect the endoscope and the endoscope host. For example, refer to Figure 9 As shown, a corresponding connector 710 is provided at one end of the connector, and the corresponding connector 710 is plugged into the connector on the endoscope handle, and the corresponding connector 710 and the connector are plugged in and matched.
