Description

Technical Field

[0001] The utility model relates to the technical field of endoscopes, and specifically, to a sunken connector, an endoscope and an endoscope system. Background Art

[0002] The working principle of the existing endoscopes is to insert them into the human body through the natural body cavity or the artificially constructed cavity for examination or treatment. When the endoscope extends into the human body, it needs to rely on the lens and the light source system to observe the internal situation, or needs to introduce liquid (such as normal saline) through the instrument channel for washing, or suck liquid and tissue samples through the suction device. In order to achieve the above functions, the endoscope and the related host equipment are docked through various functional connectors to form an endoscope system, so as to obtain a light source, a water source, a negative pressure source and a power source, and transmit signals.

[0003] For some endoscopes in the related art, in order to reduce the number of plugs of the connector, simplify the structure and improve the convenience of plugging, the electrical connector and other functional connectors are usually integrated on one plug. For example, it is integrated with the light guide rod on one plug, or integrated with the air path head and the light guide rod on one plug, so that the docking of multiple connectors can be completed by one plugging. In these connectors, the electrical connector protrudes out of the shell of the connector, and usually a pin connector composed of multiple pin needles is used. The pin needles are relatively fragile, and usually a protective sleeve is sleeved outside the pin connector to play a role in protecting and guiding the pin needles, so as to prevent the pin needles from being damaged by collision or extrusion. However, this will increase the number of parts and the assembly process, resulting in problems such as heavier weight and higher cost of the connector. Summary of the Utility Model

[0004] The purpose of the utility model is to design a sunken connector, an endoscope and an endoscope system to solve the problems of heavier weight and higher cost of the connector.

[0005] The utility model is realized through the following technical solutions:

[0006] The utility model provides a sunken connector for an endoscope, which includes a shell, an electrical connector and other functional connectors; the shell has a docking end face perpendicular to the axis of the shell, and a sink is arranged on the docking end face; the electrical connector is composed of multiple pin needles parallel to the axis of the shell, the electrical connector is connected to the shell, is accommodated in the sink, and is below the docking end face; the other functional connectors are connected to the position on the side of the docking end face of the shell and protrude from the docking end face along the axis of the shell.

[0007] When the above-mentioned setting structure is adopted, the sinking connector is provided with a sunken groove on its mating end face, and the electrical connector is accommodated in the groove and submerged under the mating end face without protruding from the groove. In this way, the groove surrounds the protruding part of the electrical connector as a whole, replacing the role of the protective sleeve in the related art, providing protection for the circumference of the electrical connector, so that the electrical connector is not easily damaged by objects coming from the side. It can be seen that the method of providing a sunken groove at the mating end face on the outer shell that is sunken relative to the mating end face can provide similar protection and guiding effects for the electrical connector without adding additional parts, compared with the method of adding a protective sleeve in the related art. Therefore, the sinking connector will reduce the weight and cost while providing a certain protection effect for the electrical connector.

[0008] At the same time, since the electrical connector is located below the mating end face, the electrical connector will be located entirely on the inner side of the outer shell, with no part protruding from the outer shell. This means that the electrical connector is no longer protected solely by a circle of wall shell located on its periphery, but can be further protected by the surrounding wall of the outer shell. This will make the damage resistance of the fragile electrical connector in the sunken connector more prominent, and can more effectively prevent damage to the connector.

[0009] In order to further better realize the present utility model, the following setting structure is particularly adopted: the sink groove and the butt end surface are integrally formed.

[0010] When the above-mentioned structure is adopted, the recessed groove and the butt end face are integrally formed parts on the housing, and no additional assembly process is required, and thus there is no need to use adhesives or set up a connection structure, which can reduce the weight and cost of the connector.

[0011] In order to further better realize the present utility model, the following setting structure is particularly adopted: the other functional joints include an air path head and / or a light guide rod.

[0012] In order to better realize the present invention, the following configuration is particularly adopted: the sink, the gas path head and the light guide rod are arranged in a straight line along the symmetry axis of the butt end surface.

[0013] When the above-mentioned setting structure is adopted, the electrical connector, the gas circuit head and the light guide rod can make full use of the available setting space on the docking end surface, so that the setting gap between the electrical connector, the gas circuit head and the light guide rod can be more ample, so that a larger electrical connector can be set to obtain richer functions.

[0014] In order to further better realize the utility model, the following setting structure is particularly adopted: the sink groove is located between the gas path head and the light guide rod, and is arranged at the eccentric position of the butt end face. Compared with the light guide rod, the sink groove is arranged closer to the gas path head.

[0015] When the above - mentioned setting structure is adopted, the electrical connector is located between the air - path head and the light - guiding rod. The air - path head and the light - guiding rod can be further used to protect the object approaching the electrical connector from a specific direction, which can improve the protection ability of the electrical connector.

[0016] Furthermore, to better implement the present utility model, the following setting structure is particularly adopted: on the docking end face, on the opposite sides of the air - path head in the radial direction perpendicular to the symmetry axis, two first vertical walls are respectively arranged. The first vertical walls extend around the air - path head along the circumferential direction of the docking end face. The outer side surfaces of the two first vertical walls and the connection line between the opposite sides in the circumferential direction of the air - path head between the outer side surfaces enclose a first protection area, and the air - path head is located within the first protection area.

[0017] When the above - mentioned setting structure is adopted, the two first vertical walls arranged on the opposite sides of the air - path head protect the air - path head through the protection area enclosed by their outer side surfaces, which can effectively reduce the possibility of the air - path head colliding with external objects, reduce the damage risk of the air - path head, and further reduce the damage risk of the connector. The air - path head is protected by two independently arranged first vertical walls at its periphery, which can reduce the weight and manufacturing difficulty of the housing while ensuring a certain protection ability for the air - path head.

[0018] Furthermore, to better implement the present utility model, the following setting structure is particularly adopted: the length by which the first vertical wall protrudes from the docking end face along the axial direction of the housing is greater than the length by which the air - path head protrudes from the docking end face along the axial direction of the housing.

[0019] When the above - mentioned setting structure is adopted, the two first vertical walls can provide better protection for the end of the air - path head.

[0020] Furthermore, to better implement the present utility model, the following setting structure is particularly adopted: on the docking end face, on the opposite sides of the light - guiding rod in the radial direction perpendicular to the symmetry axis, two second vertical walls are respectively arranged. The second vertical walls extend around the light - guiding rod along the circumferential direction of the docking end face. The outer side surfaces of the two second vertical walls and the connection line between the opposite sides in the circumferential direction of the light - guiding rod between the outer side surfaces enclose a second protection area, and the light - guiding rod is located within the second protection area.

[0021] When the above - mentioned setting structure is adopted, the two second vertical walls arranged on the opposite sides of the light - guiding rod protect the light - guiding rod through the protection area enclosed by their outer side surfaces, which can effectively reduce the possibility of the light - guiding rod colliding with external objects, reduce the damage risk of the light - guiding rod, and further reduce the damage risk of the connector. The light - guiding rod is protected by two independently arranged second vertical walls at its periphery, which can reduce the weight and manufacturing difficulty of the housing while ensuring a certain protection ability for the light - guiding rod.

[0022] Furthermore, to better implement the present utility model, the following structural arrangement is particularly adopted: An annular space for accommodating a pin shaft is formed between the inner peripheral wall of the sinking groove and the electrical connector. The pin shaft is provided with an electrical connection structure for mating with the pin. The inner peripheral wall of the sinking groove is composed of two inner arc surfaces and two flat surfaces that surround the electrical connector and are sequentially and alternately connected. The curvatures and arc lengths of the two arc surfaces are the same and are symmetrically arranged along the radial direction of the electrical connector.

[0023] When the above structural arrangement is adopted, during the mating process of the sinking connector with the female seat of the host device, the sinking groove can cooperate with the pin shaft provided on the female seat to achieve the effect of preventing rotation and anti-fooling of the sinking connector, so as to improve the mating efficiency.

[0024] Furthermore, to better implement the present utility model, the following structural arrangement is particularly adopted: The housing includes a cover shell and an end cover. One end of the cover shell is detachably connected with the end cover. Wherein, the sinking groove is arranged on the end cover, and the electrical connector and the other functional connectors are both detachably connected to the end cover.

[0025] When the above structural arrangement is adopted, the end cover is detachably connected to the cover shell, and the sinking groove, the electrical connector and the other functional connectors are arranged on the end cover, so that the end cover, the electrical connector and the other functional connectors can be assembled with the cover shell after forming a connector module, which can reduce the assembly difficulty of the sinking connector and improve the production efficiency.

[0026] The present utility model also provides an endoscope, and the endoscope includes the above-mentioned sinking connector.

[0027] The present utility model also provides an endoscope system. The endoscope system includes the above-mentioned endoscope and a host device adapted to the endoscope. The host device includes a female seat adapted to the sinking connector of the endoscope. The female seat includes a power supply and signal interface and other functional interfaces that are respectively docked with the electrical connector and other functional connectors provided on the sinking connector of the endoscope.

[0028] The present utility model has the following advantages and beneficial effects:

[0029] In the present utility model, the sunken connector is provided with a sunken groove on its docking end face. The electrical connector is accommodated in the sunken groove and is below the docking end face without protruding from the sunken groove. In this way, the sunken groove entirely surrounds the protruding part of the electrical connector, replacing the function of the protective sleeve in the related art, providing circumferential protection for the electrical connector, and making the electrical connector not easily damaged by being knocked by objects coming from the side. It can be seen that the method of setting a sunken groove relative to the docking end face on the outer shell compared with the method of adding a protective sleeve in the related art can provide a similar protective effect and guiding effect for the electrical connector without additionally increasing components. Therefore, the sunken connector can reduce the weight and cost while providing a certain protective effect for the electrical connector.

[0030] Meanwhile, since the electrical connector is below the docking end face, the electrical connector will be entirely inside the outer shell without any part protruding outside the outer shell. This will enable the electrical connector to be protected not only by the surrounding wall shell but also by the peripheral wall of the outer shell, making the anti-damage ability of the vulnerable electrical connector in the sunken connector more prominent and more effectively avoiding damage to the connector.

[0048] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other implementation manners obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope protected by the present utility model.

[0049] In the description of the present utility model, it should be noted that unless otherwise specified, the meaning of "a plurality of" is two or more; the orientation or positional relationships indicated by the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present utility model. In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0050] In the description of the present utility model, it should also be noted that, unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0051] To solve the related technical problems, the inventors also found in their research that integrating the electrical connector with one or both of the gas path connector and the light guide rod on a plug makes these integrated connectors overly concentrated in a limited area and all protrude from the housing of the connector without exception, increasing the risk of damage to the connector. For example, if one of the connectors on the connector is damaged, the entire connector is damaged. Therefore, the inventors wondered if there is a connector that can solve the problem of high risk of damage to the connector integrating multiple structures while solving the problems of weight and cost. Thus, the inventors provided the following arrangement.

[0052] On the one hand, the present application provides a sunken connector 10, which can reduce the weight and cost of the connector, as Figures 1-8 shown, and is specifically configured as the following structure:

[0053] The sunken connector 10 in this embodiment is used for an endoscope to connect the endoscope to a host device (an integrated or split device that can provide power, light source, and gas source for realizing the functions related to the endoscope) to realize related functions.

[0054] In this embodiment, the sunken connector 10 integrates the electrical connector 12 with other functional connectors 13, and the other functional connectors 13 include one or both of the gas path connector 13a and the light guide rod 13b, so that the sunken connector 10 can realize the on-off of electricity, gas, or light of the endoscope through one plugging and unplugging.

[0055] As Figure 1 and Figure 2 shown, the sunken connector 10 includes a housing 11, an electrical connector 12, and other functional connectors 13. The other functional connectors 13 include one or both of the gas path connector 13a and the light guide rod 13b.

[0056] The electrical connector 12 is used to dock with the power supply and signal interfaces adapted on the host device to enable the endoscope to realize the functions of power-on and signal transmission; the gas path connector 13a is used to dock with the gas source interface adapted on the host device to enable the endoscope to realize the gas supply function; the light guide rod 13b is used to dock with the light source interface adapted on the host device to enable the endoscope to realize the light guiding function.

[0057] As Figure 1 andFigure 2 As shown, the housing 11 has an outer peripheral surface that encloses around its axis, and the direction of this axis is the docking direction for the housing 11 to dock with the female socket of the host device. The housing 11 also includes a docking end face 111 that is perpendicular to its axis and is provided at its docking end, and a tail sleeve provided at one end far from the docking end face 111. Each cable and pipeline connected to the sunken connector 10 finally passes through the tail sleeve provided at one end of its housing 11 and is connected to the relevant devices provided in the operation part and the insertion part of the endoscope.

[0058] As Figure 1 and Figure 2 shown, the housing 11 is provided with a sunken groove 112 at its docking end face 111, and the sunken groove 112 has a depth and width sufficient to accommodate the electrical connector 12.

[0059] The electrical connector 12 is accommodated in the sunken groove 112 and fixed to the housing 11. One end of the electrical connector 12 passes through the bottom of the sunken groove 112 for connection to the cable provided inside the housing 11, and the other end of the electrical connector 12 extends axially outward from the sunken groove 112 but does not extend out of the sunken groove 112, so that the electrical connector 12 as a whole is below the docking end face 111.

[0060] Generally, the electrical connector 12 and the sunken groove 112 are in a coaxial relationship.

[0061] The electrical connector 12 is composed of multiple pin needles arranged parallel to the axis of the housing 11 and a seat body for mounting the pin needles.

[0062] The other functional connectors 13 are fixedly connected to the housing 11 at a position on the side of the docking end face 111. The other functional connectors 13 are arranged axially along the housing 11, are arranged parallel to the electrical connector 12, and the other functional connectors 13 protrude axially from the docking end face 111.

[0063] According to different host devices, the housing 11 can be a housing that is roughly flat-columnar as in Figure 1 , and of course it can also be a housing that is roughly cylindrical. The flat-columnar housing 11 belongs to a flattened structure, which can make the size smaller and the structure lighter on the premise of realizing the functions, but it puts forward more requirements for the internal device layout than the cylindrical housing.

[0064] In this embodiment, the sunken connector 10 is provided with a sunken groove 112 on its docking end face 111. The electrical connector 12 is accommodated in the groove 112 and is below the docking end face 111 without protruding from the groove 112. In this way, the groove 112 surrounds the protruding part of the electrical connector 12 as a whole, replacing the function of the protective sleeve in the related art, providing protection to the circumference of the electrical connector 12, and making the electrical connector 12 not easily damaged by being knocked by objects coming from the side. It can be seen that the method of setting the groove 112 sunken relative to the docking end face 111 on the housing 11 can provide a similar protection effect and guiding effect for the electrical connector 12 without adding extra parts compared with the method of adding a protective sleeve in the related art. Therefore, the sunken connector 10 can reduce the weight and cost while providing a certain protection effect for the electrical connector 12.

[0065] At the same time, since the electrical connector 12 is below the docking end face 111, the electrical connector 12 will be entirely inside the housing 11 without any part protruding outside the housing 11. This will enable the electrical connector 12 to be protected not only by the surrounding wall shell but also by the peripheral wall of the housing 11, making the anti-damage ability of the vulnerable electrical connector 12 in the sunken connector 10 more prominent and more effectively avoiding damage to the connector.

[0066] According to some optional embodiments, as Figures 1-8 shown, the other functional connectors 13 in the sunken connector 10 include an air passage head 13a and a light guide rod 13b at the same time. The electrical connector 12, the air passage head 13a, and the light guide rod 13b are integrated on the housing 11 and arranged parallel to each other. The electrical connector 12, the air passage head 13a, and the light guide rod 13b are distributed on the docking end face 111 of the housing 11 without interfering with each other, so that the docking of the electrical connector 12, the air passage head 13a, and the light guide rod 13b can be completed by one plugging, reducing the number of plug settings of the connector, simplifying the structure, and improving the convenience of plugging. Specifically:

[0067] The electrical connector 12 is fixedly connected to the housing 11 and is located in the space of the groove 112 below the docking end face 111, and the electrical connector 12 extends along the axial direction of the housing 11 at the same time.

[0068] The air passage head 13a is fixedly connected to the housing 11 and is located inside the docking end face 111, and extends along the axial direction of the housing 11 to protrude from the docking end face 111 at the same time.

[0069] The light guide rod 13b is fixedly connected to the housing 11 and is located inside the docking end face 111, and extends along the axial direction of the housing 11 to protrude from the docking end face 111 at the same time.

[0070] Generally, between the gas path head 13a and the light guide rod 13b, in the length protruding from the butt end surface 111, the light guide rod 13b is longer, and the diameter of the light guide rod 13b is also larger.

[0071] According to some optional embodiments, reference Figure 2 and Figure 8 On the housing 11, the recessed groove 112 and the butt end face 111 are set as two clearly distinguishable structural features on an integrally formed part. In this way, the recessed groove 112 and the butt end face 111 are integrally formed parts on the housing 11, and a structure for protecting the electrical connector 12 can be obtained without an additional assembly process, and there is no need to use adhesives or set connection structures, which can reduce the weight and cost of the connector.

[0072] According to some optional embodiments, on the housing 11, reference Figure 1 , Figure 2 and Figure 5 The sink 112, the gas path head 13a and the light guide rod 13b are arranged in a straight line along the symmetry axis of the docking end face 111, so that the electric connector 12, the gas path head 13a and the light guide rod 13b can make full use of the available space on the docking end face 111, so that the setting gap between the electric connector 12, the gas path head 13a and the light guide rod 13b can be more sufficient, so that a larger electric connector 12 can be set to obtain richer functions.

[0073] If the housing 11 is as Figure 1 In the case of the flat cylindrical housing shown, in order to fully utilize the space in the butt end face 111 , the sink 112 , the gas path head 13 a and the light guide rod 13 b should be arranged along the long axis of the butt end face 111 .

[0074] Preferably, Figure 5 As shown, the sink 112 is further arranged between the gas circuit head 13a and the light guide rod 13b, so that the electric connector 12 is located between the gas circuit head 13a and the light guide rod 13b. In this way, the electric connector 12 is located between the gas circuit head 13a and the light guide rod 13b, and the gas circuit head 13a and the light guide rod 13b can be further used to protect objects passing from a specific direction toward the electric connector 12, so as to improve the protection capability of the electric connector 12. At the same time, the sink 112 (that is, the electric connector 12) is arranged closer to the center of the docking end face 111 than the gas circuit head 13a or the light guide rod 13b, which makes the protection space outside the electric connector 12 more sufficient, which can improve the protection effect of the electric connector 12 and reduce the risk of damage to the electric connector 12.

[0075] Preferably, the sink groove 112 is disposed at an eccentric position of the butt end surface 111, that is, the setting gap between the sink groove 112 and the gas path head 13a is smaller than the setting gap between the sink groove 112 and the light guide rod 13b. Figure 5Look, the sinking groove 112 and the electrical connector 12 are arranged close to the gas path head 13a.

[0076] According to some alternative embodiments, such as Figure 1 , Figure 2 and Figure 5 shown, the housing 11 is preferably arranged as a flat columnar shell, so that the docking end face 111 is a substantially rectangular face, and its major axis is perpendicular to the minor axis.

[0077] According to some alternative embodiments, such as Figures 1-8 shown, the housing 11 is provided with a protective structure on the docking end face 111, providing a certain degree of protection for the side of the gas path head 13a. Specifically, the protective structure includes two first vertical walls 14a, and the two first vertical walls 14a are respectively arranged on the opposite sides in the radial direction perpendicular to the symmetry axis of the docking end face 111 of the gas path head 13a, so that the gas path head 13a is limited in the space between the two first vertical walls 14a.

[0078] The root of the first vertical wall 14a is fixedly connected to the docking end face 111, and it is preferably connected and fixed by an integral injection molding method.

[0079] Preferably, in order to ensure that the two first vertical walls 14a have a good protective effect on the gas path head 13a, as Figure 5 shown, the first vertical wall 14a extends along the circumferential direction of the docking end face 111 for a certain distance, and its extension trajectory also surrounds the gas path head 13a, so that the outer sides of the two first vertical walls 14a and the first connection line L1 on the opposite sides in the circumferential direction of the gas path head 13a between the outer sides can enclose a first protection area D1, and the area covered by the first protection area D1 is such that the gas path head 13a can be completely located within the first protection area D1 without any excess part.

[0080] In this embodiment, the two first vertical walls 14a arranged on the opposite sides of the gas path head 13a protect the gas path head 13a through the protection area enclosed by their outer sides, which can effectively reduce the possibility of the gas path head 13a colliding with external objects, reduce the damage risk of the gas path head 13a, and further reduce the damage risk of the connector. And the gas path head 13a is protected by two first vertical walls 14a independently arranged at its periphery. The first protection area D1 enclosed by the two first vertical walls 14a is open, which can reduce the weight and manufacturing difficulty of the housing 11 while ensuring a certain degree of protection for the gas path head 13a.

[0081] According to some alternative embodiments, such as Figure 3 , Figure 4 and Figure 8As shown, the length by which the first vertical wall 14a protrudes axially from the docking end face 111 of the outer shell 11 is greater than the length by which the gas path head 13a protrudes axially from the docking end face 111 of the outer shell 11, such that the two first vertical walls 14a can provide better protection for the end of the gas path head 13a.

[0082] According to some alternative embodiments, as Figures 1-8 shown, the outer shell 11 is provided with a protective structure on the docking end face 111 to provide a certain degree of protection for the side of the light guide rod 13b. Specifically, the protective structure includes two second vertical walls 14b, which are respectively arranged on the opposite sides in the radial direction perpendicular to the symmetry axis of the docking end face 111 of the light guide rod 13b, such that the gas path head 13a is limited within the space between the two first vertical walls 14a.

[0083] The root of the second vertical wall 14b is fixedly connected to the docking end face 111, and it is preferably connected and fixed by an integral injection molding method.

[0084] Preferably, in order to ensure that the two second vertical walls 14b have a good protective effect on the light guide rod 13b, as Figure 5 shown, the second vertical wall 14b extends along the circumferential direction of the docking end face 111 for a certain length, and its extending trajectory also extends around the light guide rod 13b, such that the outer sides of the two second vertical walls 14b and the second connecting line L2 on the opposite sides in the circumferential direction of the light guide rod 13b between the outer sides can enclose a second protective area D2, and the area covered by the second protective area D2 is such that the light guide rod 13b can be completely located within the second protective area D2 without any excess part.

[0085] In this embodiment, the two second vertical walls 14b arranged on the opposite sides of the light guide rod 13b protect the light guide rod 13b through the protective area enclosed by their outer sides, which can effectively reduce the possibility of the light guide rod 13b colliding with external objects, reduce the risk of damage to the light guide rod 13b, and further reduce the risk of damage to the connector. The light guide rod 13b is protected by two second vertical walls 14b independently arranged around it, which can reduce the weight and manufacturing difficulty of the outer shell 11 while ensuring a certain degree of protection for the light guide rod 13b.

[0086] It can be seen that according to some alternative embodiments, as Figures 1-8As shown, a protective structure is provided on the docking end face 111 of the outer shell 11 to provide a certain degree of protection for the side of the gas circuit head 13a. The protective structure also includes the two first vertical walls 14a and the two second vertical walls 14b described in the above embodiments, and the two first vertical walls 14a and the two second vertical walls 14b are also arranged in accordance with some of the setting methods described in the above embodiments. This can reduce the risk of damage to the connector integrating the three types of connectors: the electrical connector 12, the gas circuit head 13a, and the light guide rod 13b.

[0087] Preferably, when the sink 112, the gas circuit head 13a, and the light guide rod 13b are arranged in a straight line, referring to Figure 1 , Figure 2 and Figure 5 , the gas circuit head 13a and the light guide rod 13b are arranged along the circumference of the docking end face 111 close to it. Specifically, as long as the first vertical wall 14a and the second vertical wall 14b can respectively provide sufficient protection for the gas circuit head 13a and the light guide rod 13b, the gas circuit head 13a and the light guide rod 13b are arranged as close as possible to the circumference of the docking end face 111. This can make the space around the electrical connector 12 large enough to accommodate a larger and more functional electrical connector 12, so as to expand more application scenarios.

[0088] According to some alternative embodiments, as shown in Figure 2 and Figure 5 , an annular space is formed between the inner peripheral wall of the sink 112 and the electrical connector 12. The annular space is used to accommodate the pin shaft of the electrical connection structure provided on the female seat for installing and docking with the pin when the down - type connector 10 is inserted into the female seat of the host device. The inner peripheral wall of the sink 112 is composed of two inner arc surfaces 1121 and two flat surfaces 1122 that surround the electrical connector 12 and are sequentially and alternately connected. The curvatures and arc lengths of the two arc surfaces 1121 are the same and are symmetrically arranged along the radial direction of the electrical connector 12, so that the sink 112 forms a pin hole matching the pin shaft.

[0089] In this embodiment, during the process of inserting the down - type connector 10 into the female seat of the host device, the sink 112 can cooperate with the pin shaft provided on the female seat to achieve the anti - rotation and anti - misalignment effects of the down - type connector 10, so as to improve the insertion efficiency. In addition, the sink 112 arranged in this way forms an anti - misalignment and anti - rotation structure, and there is no need to provide an anti - misalignment and anti - rotation structure on the outer peripheral surface of the outer shell 11, which can effectively simplify the outer shell structure and reduce costs. In addition, since the sink 112 arranged in this way forms an anti - misalignment and anti - rotation structure, there is no need to separately provide a relevant anti - misalignment and anti - rotation structure on the outer peripheral surface of the light guide rod 13b, which can reduce the axial dimension of the light guide rod 13b.

[0090] According to some alternative embodiments, as shown in Figures 6-8As shown, the housing 11 includes a cover 11a and an end cap 11b, and the cover 11a and the end cap 11b are two independently produced components. One end of the cover 11a is provided with a tail sleeve, and the other end is provided with an opening. The end cap 11b is detachably mounted on the end with the opening provided on the cover 11a. A sealing ring is connected to the edge of the cover 11a and is sealed with the inner peripheral wall of the cover 11a through the sealing ring.

[0091] The cover 11a provides the outer peripheral surface of the housing 11, and the end cap 11b provides at least a part but mainly the central part of the docking end face 111 of the housing 11. The remaining part of the docking end face 111 is provided by the part of the cover 11a that is not blocked by the end cap 11b at the docking end face.

[0092] As Figure 8 shown, a sunk groove 112 is provided in the end cap 11b, and the electrical connector 12 and other functional connectors 13 are both detachably connected to the end cap 11b to form a connector module.

[0093] Preferably, the sunk groove 112 is integrally formed on the end cap 11b, and the first vertical wall 14a and the second vertical wall 14b are integrally formed on the end cap 11b.

[0094] In this embodiment, the end cap 11b is detachably connected to the cover 11a, and the sunk groove 112, the electrical connector 12 and other functional connectors 13 are provided on the end cap 11b, so that the end cap 11b, the electrical connector 12 and other functional connectors 13 can be assembled with the cover 11a after forming the connector module, which can reduce the assembly difficulty of the down - type connector 10 and improve the production efficiency.

[0095] On the other hand, the present application provides an endoscope, especially adopting the following setting structure:

[0096] In this embodiment, the endoscope includes the down - type connector 10 in any of the above - mentioned embodiments.

[0097] The down - type connector 10 is connected to the operation part of the endoscope through a cable to be connected to the relevant devices inside the operation part and the insertion part.

[0098] The mirror body of the endoscope can be a mirror body with optical fibers or a mirror body without optical fibers. The mirror body with optical fibers is preferably used in combination with the down - type connector 10 integrated with a light guide rod 13b.

[0099] According to some alternative embodiments, the down - type connector 10 is detachably connected to the operation part of the endoscope.

[0100] On the other hand, the present application provides an endoscope, especially adopting the following setting structure:

[0101] In this embodiment, the endoscope system includes the endoscope in any of the above embodiments and a host device adapted to the endoscope. The host device includes a female socket adapted to the sunken connector 10 of the endoscope. The female socket includes a power supply and signal interface and other functional interfaces respectively docked with the electrical connector 12 and other functional connectors 13 provided on the sunken connector 10 of the endoscope. For example, when the sunken connector 10 integrates an electrical connector 12, a gas path head 13a and a light guide rod 13b, the host device includes a processor, a gas pump and a light source device. The power supply and signal interfaces, gas source interfaces and light source interfaces of these devices are integrated on a single female socket.

[0102] According to some alternative embodiments, in the host device, the processor, the gas pump and the light source device are integrated within the housing of a single device.

[0103] As described above, the above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention.
