DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0033] The terms "first", "second", etc. in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0034] In each embodiment of the present application, "proximal end" and "distal end" refer to the position of each component relative to the user in the use environment, wherein the end closer to the user is designated as the "proximal end" and the end farther from the user is designated as the "distal end".

[0035] The host in the related art usually has multiple interfaces for the handle to be plugged in. Different types of endoscopes have different first terminal modules in the handle connectors. In order to adapt to different endoscopes, the second terminal modules in the multiple interfaces of the host are also different. Since the second terminal module is located inside the host shell and the appearance of each interface is the same, when plugging, it is difficult for the operator to directly observe whether each interface is compatible with the handle connector through the appearance of the interface, so the operator can only try to match the handle connector with the host interface one by one; on the other hand, during the plugging process of the connector and the interface, it is necessary to rotate the connector to achieve circumferential positioning of the connector and the interface, which makes the operation process cumbersome, increases the workload of the operator, and reduces the plugging efficiency.

[0036] To this end, the present application provides a plug-in assembly, which provides an identification part on the shell of the connector and the interface, and different types of connectors and interfaces can be identified based on the identification part, thereby improving the plug-in efficiency; further, the connector and the interface can also be aligned in the circumferential direction through the identification part, which can not only further improve the plug-in efficiency of the connector and the interface, but also compared to setting two groups of identification parts to respectively realize the matching identification of the connector and the interface and the circumferential alignment identification of the connector and the interface, the present application can realize two functions through one group of identification parts, and also helps to simplify the structure of the plug-in assembly.

[0037] The following is combined with Figures 1 to 9 , the plug-in assembly and endoscope system provided in the embodiments of the present application are described in detail through specific embodiments and their application scenarios.

[0038] The first aspect of this embodiment provides a detailed description of the plug-in assembly.

[0039] The plug assembly of this embodiment is applied to an endoscope system, specifically, to connect an endoscope handle to an all-in-one device 300. The plug assembly of this embodiment is particularly suitable for the case where multiple endoscope handles need to be plugged into the all-in-one device 300.

[0040] The plug-in assembly of this embodiment includes a connector 110 and an interface 120. Figure 1 to Figure 6 The connector 110 is disposed on one of the distal end of the adapter cable 210 of the handle or the housing 310 of the all-in-one device 300, and the interface 120 is disposed on the other of the adapter cable 210 and the housing 310. By plugging the connector 110 and the interface 120, the endoscope handle and the all-in-one device can be connected, thereby enabling data transmission. Figure 1 , Figure 5 and Figure 6 A schematic diagram showing a connector 110 disposed at the distal end of a transfer cable 210 of a handle is shown. Figure 1 to Figure 3 A schematic diagram showing that the interface 120 is disposed in the housing 310 of the all-in-one device 300 is shown.

[0041] The connector 110 includes a first housing 111 and a first terminal module 112. The first housing 111 can protect the first terminal module 112. Figure 5 and Figure 6 The connector 110 has at least two types, and the first terminal modules 112 of connectors 110 of different types are different, that is, the plug-in assembly has at least two connectors 110 with different first terminal modules 112. The number of connectors 110 of each type can be one, or two or more. Figure 1 and Figure 5 A schematic diagram showing one type of connector 110 having two connectors is shown.

[0042] The interface 120 includes a second housing 121 and a second terminal module 122. The second housing 121 can protect the second terminal module 122. Figure 4 The interface 120 has at least two models, and the second terminal modules 122 of different models of interfaces 120 are different, that is, the plug-in component has at least two interfaces 120 with different second terminal modules 122. The number of each model of interface 120 can be one, or two or more. Figure 1 to Figure 4 A schematic diagram showing one type of interface 120 having two interfaces is shown.

[0043] Preferably, at least two types of connectors 110 have at least two first identification portions 110a, and the first identification portions 110a are arranged on the first housing 111, such as Figure 1 and Figure 5That is, the first shell 111 of each connector 110 is provided with a first identification portion 110a, and the connectors 110 with different first terminal modules 112 have different first identification portions 110a thereon, such as Figure 1 and Figure 5 Specifically, the connector 110 has two types of first terminal modules 112, and the corresponding first identification parts 110a also have two types; the connector 110 has three types of first terminal modules 112, and the corresponding first identification parts 110a also have three types.

[0044] Preferably, at least two types of interfaces 120 have at least two types of second identification parts 120a, and the second identification parts 120a are arranged on the housing 310, such as Figure 1 to Figure 4 That is, each interface 120 corresponds to a second identification portion 120a, and different interfaces 120 of the second terminal modules 122 have different second identification portions 120a thereon, such as Figure 1 to Figure 4 Specifically, the interface 120 has two types of second terminal modules 122, and the corresponding second identification parts 120a also have two types; the interface 120 has three types of second terminal modules 122, and the corresponding second identification parts 120a also have three types.

[0045] More preferably, the type of the second identification portion 120a matches the first identification portion 110a, which can facilitate quick identification of the second identification portion 120a that matches the first identification portion 110a, thereby quickly identifying the interface 120 that matches the connector 110. Exemplarily, when the first identification portion 110a is a graphic, the second identification portion 120a is also a graphic, such as Figure 1 to Figure 5 When the first identification portion 110a is a number, the second identification portion 120a is also a number, such as Figure 7 to Figure 9 shown.

[0046] According to an optional embodiment, the first identification portion 110a and the second identification portion 120a are at least two of the graphics. Figure 1 to Figure 5 As shown, the first identification portion 110a includes two types, an arrow and a triangle. Correspondingly, the second identification portion 120a also includes two types, an arrow and a triangle. The connector 110 with an arrow identification can be matched and plugged with the interface 120 with an arrow identification, and the connector 110 with a triangle identification can be matched and plugged with the interface 120 with a triangle identification.

[0047] According to another optional embodiment, the first identification portion 110a and the second identification portion 120a are at least two of numbers. Figure 7 to Figure 9As shown, the first identification portion 110a includes three types of numbers "1", "2", and "3". Correspondingly, the second identification portion 120a also includes three types of numbers "1", "2", and "3". The connector 110 with the number "1" identification can be matched and plugged with the interface 120 with the number "1" identification, the connector 110 with the number "2" identification can be matched and plugged with the interface 120 with the number "2" identification, and the connector 110 with the number "3" identification can be matched and plugged with the interface 120 with the number "3" identification.

[0048] According to another optional embodiment, the first identification portion 110a and the second identification portion 120a are at least two of graphics and numbers. Exemplarily, the first identification portion 110a includes two types of arrows and numbers "1", and correspondingly, the second identification portion 120a also includes two types of arrows and numbers "1". The connector 110 with arrows can be matched and plugged with the interface 120 with arrows, and the connector 110 with numbers "1" can be matched and plugged with the interface 120 with numbers "1".

[0049] In the plug assembly of this embodiment, when the connector 110 and the interface 120 are plugged into each other and circumferentially aligned, the first identification portion 110a is located at a position aligned with the second identification portion 120a, so that the connector 110 and the interface 120 can be plugged into each other and circumferentially aligned based on the matching and alignment of the first identification portion 110a and the second identification portion 120a, such as Figure 1 or Figure 7 shown.

[0050] That is, the first identification portion 110a and the second identification portion 120a of this embodiment have at least the following two functions: one is that whether the connector 110 can be plugged into the interface 120 can be determined by matching the first identification portion 110a with the second identification portion 120a (such as matching arrows with arrows, and matching triangles with triangles); the second is that when the first identification portion 110a on the connector 110 matches the second identification portion 120a on the interface 120, whether the connector 110 and the interface 120 are aligned in the circumferential direction can also be determined by whether the first identification portion 110a on the connector 110 and the second identification portion 120a on the interface 120 are aligned.

[0051] The plug-in assembly of this embodiment can identify different types of connectors 110 and interfaces 120 through the first identification portion 110a and the second identification portion 120a, and can also realize the alignment of the connector 110 and the interface 120 in the circumferential direction through the first identification portion 110a and the second identification portion 120a.

[0052] Since the first identification portion 110a and the second identification portion 120a are respectively arranged on the first shell 111 and the second shell 121, they have the advantage of being easy to identify, which can improve the plug-in efficiency and solve the technical problem of the endoscope system in the related art that the connector 110 and the interface 120 are difficult to identify.

[0053] On the other hand, in the plug-in assembly of the present embodiment, the first identification portion 110a and the second identification portion 120a not only realize the identification of connectors 110 and interfaces 120 of different models, but also have the function of realizing the alignment of connectors 110 and interfaces 120 in the circumferential direction. Not only can the connector 110 and the interface 120 be quickly plugged in, but also compared to setting two groups of identification portions to respectively realize the matching identification of connectors 110 and interfaces 120 and the circumferential alignment identification of connectors 110 and interfaces 120, the present application can realize two functions through one group of identification portions, and also helps to simplify the structure of the plug-in assembly.

[0054] According to an optional embodiment, the first identification portion 110a and the first shell 111 are an integrated structure, that is, the first identification portion 110a and the first shell 111 are integrally formed, thereby simplifying the production process of the connector 110. Not limited to this, the first identification portion 110a can also be fixed to the surface of the first shell 111. Exemplarily, the first identification portion 110a can be fixed to the surface of the first shell 111 by pasting, printing, etc.

[0055] According to an optional embodiment, the second identification portion 120a and the second shell 121 are an integrated structure, that is, the second identification portion 120a and the second shell 121 are integrally formed, thereby simplifying the production process of the interface 120. Not limited to this, the second identification portion 120a can also be fixed to the surface of the second shell 121. Exemplarily, the second identification portion 120a can be fixed to the surface of the second shell 121 by pasting, printing, etc.

[0056] According to an optional embodiment, the connector 110 further includes a first positioning portion 113, and the first positioning portion 113 is disposed on the first housing 111. Figure 5 Specifically, the first positioning portion 113 is located at the portion of the first housing 111 that is plugged into the interface 120. The interface 120 also includes a second positioning portion 123, which is disposed on the inner wall of the second housing 121, as shown in FIG. Figure 4 Specifically, the second positioning portion 123 is located at the portion of the second housing 121 that is plugged with the connector 110 .

[0057] Preferably, the first positioning portion 113 is one of a protrusion or a groove, and the second positioning portion 123 is the other of the protrusion or the groove, and the shape of the protrusion matches the shape of the groove. Figure 5 FIG. 1 shows a schematic diagram in which the first positioning portion 113 is a convex block. Figure 4 1 shows a schematic diagram of the second positioning portion 123 being a groove. More preferably, the first positioning portion 113 extends along the axial direction of the joint 110, and the second positioning portion 123 extends along the axial direction of the interface 120, thereby enhancing the stability of the circumferential positioning of the joint 110 and the interface 120. Exemplarily, both the protrusion and the groove are long rectangular structures, and the protrusion can be snapped into the groove, such as Figure 4 and Figure 5 shown.

[0058] The plug-in assembly of the preferred technical solution of this embodiment can fix the connector 110 and the interface 120 in the circumferential direction through the snap connection between the first positioning portion 113 and the second positioning portion 123, thereby achieving preliminary fixation of the connector 110 and the interface 120.

[0059] Preferably, the number of the first positioning portions 113 is at least two, and at least two first positioning portions 113 are distributed along the circumferential direction of the first shell 111; the number of the second positioning portions 123 is at least two, and at least two second positioning portions 123 are distributed along the circumferential direction of the second shell 121, thereby ensuring the reliability of the circumferential positioning of the existing joint 110 and the interface 120.

[0060] According to an optional embodiment, the first identification portion 110a is disposed on the upper surface of the first housing 111, and the central axis of the first identification portion 110a is aligned with the central axis of the first positioning portion 113. Figure 5 Specifically, after the connector 110 and the interface 120 are plugged together, the first identification portion 110a is located at the upper part of the first shell 111. At the same time, when the first identification portion 110a and the first positioning portion 113 are in the same plane, the central axes of the two coincide with each other. When the first identification portion 110a and the first positioning portion 113 are in different planes, the central axes of the two are parallel to each other and coincide with each other in the vertical direction. Figure 5 shown.

[0061] Similarly, the second identification portion 120a is disposed on the upper surface of the housing 310, and the central axis of the second identification portion 120a is aligned with the central axis of the second positioning portion 123. Figure 4 Specifically, the central axis of the second identification portion 120a is parallel to the central axis of the second positioning portion 123, and the two overlap each other in the vertical direction, as shown in FIG. Figure 4 shown.

[0062] Without limitation thereto, the second identification portion 120a may also be disposed on the front side surface of the housing 310 (the side where the interface 120 is disposed), in which case the central axis of the second identification portion 120a and the central axis of the second positioning portion 123 are perpendicular to each other.

[0063] The plug-in assembly of the preferred technical solution of this embodiment is to align the central axis of the first identification portion 110a with the central axis of the first positioning portion 113, and the central axis of the second identification portion 120a with the central axis of the second positioning portion 123. When the operator plugs the connector 110 into the interface 120, the first identification portion 110a and the second identification portion 120a are aligned to ensure that the first positioning portion 113 can be aligned with the second positioning portion 123, thereby achieving circumferential positioning of the connector 110 and the interface 120. This alignment method has the advantage of being easy to identify because the first identification portion 110a and the second identification portion 120a are located outside the first shell 111 and the second shell 121, respectively. At the same time, it can also reduce the steps of rotational alignment when the connector 110 and the interface 120 are plugged in, which can further improve the plug-in efficiency of the two.

[0064] According to an optional embodiment, the connector 110 further includes a first fixing portion 114, which is disposed on the first shell 111, and the interface 120 further includes a second fixing portion 124, which is disposed on the inner wall of the second shell 121, and based on the clamping of the first fixing portion 114 and the second fixing portion 124, the connector 110 is fixedly connected to the interface 120, such as Figure 4 and Figure 5 shown.

[0065] Figure 4 and Figure 5 1 shows only one connector 110 with a first fixing portion 114 and one interface 120 with a second fixing portion 124. It is known that the other two connectors 110 may also be provided with corresponding first fixing portions 114, and the other two interfaces 120 may also be provided with corresponding second fixing portions 124.

[0066] Exemplarily, the first fixing portion 114 is one of a slot and a buckle, and the second fixing portion 124 is the other of the slot and the buckle, and the buckle can be snapped into the slot. Figure 5 A schematic diagram showing a buckle provided on the connector 110 is shown. Figure 4 A schematic diagram showing a card slot provided on the interface 120 is shown.

[0067] In the plug-in assembly of the preferred technical solution of this embodiment, the clamping connection between the first fixing portion 114 and the second fixing portion 124 can not only further achieve the limitation of the connector 110 and the interface 120 in the circumferential direction, but also achieve the limitation of the connector 110 and the interface 120 in the axial direction, thereby fixing the connector 110 in the interface 120.

[0068] According to an optional embodiment, the connector 110 further includes an anti-slip portion 115, which is disposed on the first housing 111. Figure 5As shown. Exemplarily, the anti-slip portion 115 is a convex strip, and the convex strip is arranged along the circumferential direction of the first shell 111, as shown in FIG. Figure 5 When the connector 110 is plugged into the interface 120 , the operator can hold the anti-slip portion 115 to facilitate the application of force.

[0069] The second aspect of this embodiment describes the endoscope system in detail.

[0070] The endoscope system of this embodiment includes an endoscope assembly and an all-in-one device 300. The endoscope assembly and the all-in-one device 300 are connected via a plug assembly, and the plug assembly is a plug assembly of any technical solution in this embodiment. The endoscope assembly includes an endoscope handle and an insertion part (the structure of the endoscope handle and the insertion part are not shown in the figure, and can be an existing structure), and the all-in-one device 300 includes a housing 310 and a circuit board located in the housing 310. The remaining structures of the endoscope assembly and the all-in-one device 300 can be the same as those in the prior art, and will not be repeated here.

[0071] The endoscope system of this embodiment has a plug-in component of any one of the technical solutions in this embodiment. When multiple endoscope components need to be connected to the all-in-one device 300, it is easy to identify the interface corresponding to the endoscope connector, which can achieve quick plug-in between the connector and the interface and simplify the structure of the plug-in component.
