[0038] Please refer to Figures 1 to 5 The utility model provides a kind of plug 100 for endoscope and the endoscope system applied by it. Among them, in addition to plug 100 for endoscope, endoscope system can also include endoscope socket matched with plug 100 for endoscope and at least two bodies. Among them, plug 100 for endoscope and endoscope socket are one-to-one corresponding to be arranged at two bodies. The specific type of two bodies is not limited to, can be but not limited to: one of the bodies is endoscope, and the other body is external control host computer, by the insertion of endoscope socket and plug 100 for endoscope, the electrical signal intercommunication between endoscope and control host computer can be realized. Or one of the bodies is endoscope, and the other body is external light source device, by the insertion of endoscope socket and plug 100 for endoscope, the light emitted by external light source device can be guided to endoscope via optical fiber and inserted into the head end structure of main body.

[0039] For the convenience of understanding, in the following embodiments, the endoscope system as a whole is taken as an example for illustration, which has vertical, horizontal and longitudinal directions arranged in a cross manner. In specific applications, the vertical direction can correspond to the direction of gravity, and has upward and downward directions arranged oppositely.

[0040] In view of this, specifically, the endoscope plug 100 includes a connection housing 110, an electrical connection protrusion, and a protruding rib 130. The connection housing 110 includes a connection end plate 111; the electrical connection protrusion 120 is protrudingly arranged on the connection end plate 111, and is used for pluggable cooperation with an electrical connection slot of an endoscope socket; the protruding rib 130 is protrudingly arranged on the connection end plate 111, and is arranged at a side of the electrical connection protrusion 120 in at least one dimension direction, and in the dimension direction, a projection area of the protruding rib 130 at least partially overlaps with a projection area of the electrical connection protrusion 120.

[0041] In the technical scheme provided by the utility model, when the electrical connection protrusion 120 is in a non-plugging state, the protruding rib 130 can shield and protect the electrical connection protrusion 120 in at least one dimension direction, so that when an external force is applied along the dimension direction, the protruding rib 130 can effectively prevent the external force from damaging the electrical connection protrusion 120; and the protruding rib 130 can also effectively prevent the external environment from polluting the electrical connection protrusion 120 in the dimension direction, so as to ensure that the electrical performance of the electrical connection protrusion 120 is always maintained in the best state; when the electrical connection protrusion 120 is plugged with the electrical connection slot in the matched endoscope socket, the protruding rib 130 can also effectively shield and protect the plugging parts of the two, avoid abnormal deformation of the plugging parts in the dimension direction, and ensure that external foreign matters are difficult to enter the plugging parts of the two in the dimension direction, so as to ultimately help improve the plugging quality of the endoscope plug 100 and the endoscope socket.

[0042] Please specifically combine Figures 1 to 5 The endoscope plug 100 extends in the longitudinal direction, and includes the connection housing 110 and a connection cable connected in sequence in the longitudinal direction. One section of the connection cable is arranged in the connection housing 110, and the other section extends to be connected with a machine body. The shell wall of the connection housing 110 away from the connection cable in the longitudinal direction constitutes the connection end plate 111, which can specifically extend along the vertical and horizontal directions, respectively.

[0043] It can be understood that the endoscope plug 100 is matched with the endoscope socket. The endoscope socket includes a docking shell, and the endoscope socket defines an electrical interface slot. The electrical interface slot is connected to the electrical interface protrusion 120 through plugging. At this time, in order to achieve tight connection during repeated plugging of the electrical interface slot and the electrical interface protrusion 120, a buckle can be provided on one of the connection shell 110 and the docking shell, and a buckle hole is provided on the other. When the electrical interface slot and the electrical interface protrusion 120 are plugged into place, the buckle and the buckle hole are buckled and fixed, and the electrical interface slot and the electrical interface protrusion 120 are locked in the current plugged-in state.

[0044] Specifically, a part of the electrical interface protrusion 120 is accommodated in the connection shell 110 and connected with the connection cable. Another part of the electrical interface protrusion 120 protrudes along the longitudinal direction and passes through the connection end plate 111. It can be understood that the specific form of the electrical interface protrusion 120 is not limited, for example Figures 1 to 5 As shown, it can be roughly plate-shaped or sheet-shaped along the transverse direction.

[0045] The size direction of the electrical interface protrusion 120 described above refers to the length direction, width direction, thickness direction, etc. of the electrical interface protrusion 120. Specifically, when applied to the endoscope plug 100, the size direction of the electrical interface protrusion 120 includes the transverse direction, longitudinal direction and vertical direction described above. The protruding rib 130 can be selectively arranged on any side of the electrical interface protrusion 120 in the transverse direction, longitudinal direction and / or vertical direction, and the function of the protruding rib 130 in this direction is achieved. The protruding rib 130 is spaced apart from the electrical interface protrusion 120, so that a gap is formed for smooth plugging of the electrical interface protrusion 120 and the electrical interface slot.

[0046] Specifically, the protruding rib 130 can first shield and protect the electrical interface protrusion 120. Especially when the endoscope plug 100 is in an idle state, that is, not plugged with the endoscope socket, the protruding rib 130 can effectively protect the electrical interface protrusion 120 from being damaged by external impact, and can also prevent the electrical interface protrusion 120 from being contaminated by impurities, water vapor, sweat stains brought by the operator when grabbing, etc. in the external environment.

[0047] Then, if the docking shell or other structure in the endoscope socket is pre-provided with a clearance space at the position corresponding to the protruding rib 130, when the endoscope plug 100 is used in combination with the endoscope socket, the clearance space can accommodate the protruding rib 130 during the plugging process of the electrical contact protrusion 120 and the electrical contact slot. At this time, the protruding rib 130 is located beside the plugging position of the electrical contact protrusion 120 and the electrical contact slot, and can simultaneously play a structure reinforcing and protecting role for the plugging position of the electrical contact protrusion 120 and the electrical contact slot. The structure reinforcing role is specifically, for example, the mutual abutment of the protruding rib 130 and other components at the clearance space can strengthen the plugging strength of the electrical contact protrusion 120 and the electrical contact slot.

[0048] Further, if the above-mentioned clearance space is specifically provided as a guide groove that can be connected with the protruding rib 130 in sliding or rolling manner, when the endoscope plug 100 is used in combination with the endoscope socket, the sliding or rolling connection between the protruding rib 130 and the guide groove can accurately guide the plugging process of the electrical contact protrusion 120 and the electrical contact slot, and to some extent, limit the plugging direction of the electrical contact protrusion 120 and the electrical contact slot, so as to avoid the structure damage of the electrical contact protrusion 120 or the electrical contact slot due to the deviation of the plugging direction during the plugging process.

[0049] In view of the above, the protruding height of the protruding rib 130 determines to some extent the effective area, for example, the shielding area of the electrical contact protrusion 120 in the corresponding size direction. Therefore, in the present embodiment, in order to achieve as much as possible the complete shielding of the electrical contact protrusion 120 in the size direction, the protruding height of the protruding rib 130 relative to the connecting end plate 111 can be set to be not less than the protruding height of the electrical contact protrusion 120. For example Figures 1 to 5 As shown, the protruding height of the protruding rib 130 can be substantially the same as the protruding height of the electrical contact protrusion 120, that is, the protruding rib 130 can completely shield the electrical contact protrusion 120, and the free end surface of the protruding rib 130 and the free end surface of the electrical contact protrusion 120 are substantially flush, which helps to save the material of the protruding rib 130.

[0050] Of course, according to actual needs, in other applications, the protruding height of the protruding rib 130 can be set to be greater than the protruding height of the electrical contact protrusion 120, so that the protruding rib 130 can completely shield the electrical contact protrusion 120 and also form an extended rib segment. The extended rib segment can play other roles according to actual needs. For example, when the guide groove is pre-provided as mentioned above, the extended rib segment can make the movable matching surface between the protruding rib 130 and the guide groove larger, thereby helping to optimize the guiding effect.

[0051] It should be noted that the convex rib 130 and the connecting end plate 111 can be integrally formed, or can be connected after being separately formed, in a detachable or non-detachable manner. The detachable connection can be one or more of, for example, screwing, buckling, bonding, and adsorption. The non-detachable connection can be, for example, welding or hot pressing.

[0052] Based on the above one or more embodiments, the convex rib 130 can be provided in one or more in the single size direction of the electrical connection bump 120. Alternatively, the convex rib 130 can also be provided in one or more in at least two size directions of the electrical connection bump 120.

[0053] Specifically, in an embodiment, the electrical connection bump 120 has a first size direction and a second size direction arranged in a cross manner. The first size direction is, for example, the lateral direction of the electrical connection bump 120, and the second size direction is, for example, the vertical direction of the electrical connection bump 120. Figures 1 to 5 Figures 1 to 5 At this time, the convex rib 130 can include a first rib plate 131 and a second rib plate 132. The first rib plate 131 is located on one side of the electrical connection bump 120 in the first size direction and extends in the second size direction. In the first size direction, the projection area of the first rib plate 131 at least partially overlaps the projection area of the electrical connection bump 120, and at least can shield and protect the electrical connection bump 120 in the first size direction. The second rib plate 132 is located on one side of the electrical connection bump 120 in the second size direction and extends in the first size direction. The second rib plate 132 is connected to the first rib plate 131. Specifically, in the second size direction, the projection area of the second rib plate 132 can be arranged to at least partially overlap the projection area of the electrical connection bump 120, so as to shield and protect the electrical connection bump 120 in the second size direction. Alternatively, the projection area of the second rib plate 132 can be arranged to be staggered with the projection area of the electrical connection bump 120, so that the second rib plate 132 only plays a guiding role as described above, and at the same time, the structural strength of the first rib plate 131 can be enhanced by means of the second rib plate 132.

[0054] The first rib plate 131 and the second rib plate 132 as described above can also be integrally formed, or can be connected after being separately formed, in a detachable or non-detachable manner. The detachable connection can be one or more of, for example, screwing, buckling, bonding, and adsorption. The non-detachable connection can be, for example, welding or hot pressing.

[0055] ​Since the first size direction generally corresponds to the transverse direction and the second size direction generally corresponds to the vertical direction, the two directions are generally perpendicular, that is, the first rib plate 131 and the second rib plate 132 are generally perpendicular, forming an included angle of about 90°. At this time, further, the connection of the first rib plate 131 and the second rib plate 132 can be smoothly transitioned, for example, an arc chamfer is provided at the connection of the two, or a straight bevel transition connection is provided at the connection of the two, to avoid forming a sharp structure at the connection of the two.

[0056] The first rib plate 131 and the second rib plate 132 can be arranged in groups on one side of the electrical connection protrusion 120 in the first size direction, or in an embodiment, two first rib plates 131 are arranged on opposite sides of the electrical connection protrusion 120 in the first size direction. At this time, the second rib plate 132 can be arranged one-to-one with the two first rib plates 131 respectively; or the second rib plate 132 is arranged as one, and the second rib plate 132 extends along the first size direction to connect with the two first rib plates 131.

[0057] Then, the first rib plate 131 is generally arranged to be connected and fixed with the connecting end plate 111, which can be integrally formed as described above, or can be detachably connected or non-detachably connected after being separately formed. At this time, the second rib plate 132 can also be arranged to be connected and fixed with the connecting end plate 111, or can be arranged to be connected and fixed only with the two first rib plates 131, while being spaced apart from the connecting end plate 111. A first visible window is formed between the second rib plate 132 and the connecting end plate 111. The first visible window is closer to the connection between the electrical connection protrusion 120 and the connecting end plate 111, and can be used to visually check the part of the electrical connection protrusion 120 to confirm that it is in a relatively good installation state; or the first visible window can also be used to clean the connection between the electrical connection protrusion 120 and the connecting end plate 111.

[0058] Of course, when the second rib plate 132 is also connected and fixed with the connecting end plate 111, or the caliber of the first visible window described above is small, further, in an embodiment, a through hole 132a is provided in the second rib plate 132 along the second size direction, and in the second size direction, the projection area of the through hole 132a at least partially overlaps with the projection area of the electrical connection protrusion 120. At this time, the connection and fixation of the second rib plate 132 and the connecting end plate 111 can help to enhance the structural strength of the second rib plate 132. The through hole 132a constitutes a second visible window. The through hole 132a is opposite to at least part of the electrical connection protrusion 120, and can be used to check the structural state and installation state of the electrical connection protrusion 120, and can be used to clean and wipe the electrical connection protrusion 120, etc.

[0059] Further, the through hole 132a is arranged at a portion of the second rib plate 132 away from the connecting end plate 111. That is, the through hole 132a is arranged close to the free end of the electrical contact protrusion 120. In this way, on the one hand, the second rib plate 132 can reserve sufficient plate surface for connecting and fixing with the connecting end plate 111; on the other hand, the second rib plate 132 can at least focus on shielding and protecting the connecting portion of the electrical contact protrusion 120 and the connecting end plate 111 in the second dimension direction, in addition, the through hole 132a can define a second visual window only for a portion of the electrical contact protrusion 120 close to the free end, which does not affect the visual viewing effect, and to a certain extent, limits the cleaning and wiping area, so as to avoid the cleaning and wiping operation affecting the installation between the electrical contact protrusion 120 and the connecting end plate 111. In actual application, the through hole 132a can specifically penetrate through one end of the second rib plate 132 away from the connecting end plate 111.

[0060] In addition, it needs to be noted that when the guide groove is arranged at the docking shell of the endoscope socket as described above, the guide groove includes a first guide groove corresponding to the first rib plate 131 and a second guide groove corresponding to the second rib plate 132. Among them, the first guide groove and the second guide groove are communicated.

[0061] In view of the above, the first dimension direction corresponds to the length direction of the electrical contact protrusion 120, and the second dimension direction corresponds to the width direction of the electrical contact protrusion 120. In this way, the electrical contact protrusion 120 forms a larger extension plate surface in the first dimension direction, and especially when the through hole 132a is arranged, based on the through hole 132a, almost all the plate surface of the electrical contact protrusion 120 in the length direction can be visually viewed and cleaned.

[0062] In addition, the above-mentioned protruding ribs 130 are generally arranged to extend straight along the longitudinal direction. However, this does not constitute a limitation on the specific forms of the extension direction and extension shape of the protruding ribs 130. According to actual needs, the protruding ribs 130 can also be arranged to be inclined relative to the longitudinal direction, for example, to extend gradually in the direction away from the connecting end plate 111 and inclined toward the electrical connection protrusion 120. In addition, the protruding ribs 130 have a certain elastic deformation capacity in the direction close to and away from the electrical connection protrusion 120. Taking the two first rib plates 131 arranged respectively on the two sides of the electrical connection protrusion 120 as an example, as described above. In this way, when the endoscope plug 100 is in an idle state, the two first rib plates 131 are in a natural undeformed state, and the free sections thereof are closer to the electrical connection protrusion 120, which can play a certain folding protection role on the side of the electrical connection protrusion 120 away from the connecting end plate 111. When the endoscope plug 100 is inserted into the endoscope socket, the first rib plates 131 are guided by the above-mentioned avoiding space or guide groove to expand and deform in the direction away from the electrical connection protrusion 120. On the one hand, this helps to provide space for the electrical connection protrusion 120 and the electrical connection slot to be smoothly inserted, and on the other hand, after the electrical connection protrusion 120 and the electrical connection slot are smoothly inserted into position, the two first rib plates 131 both form a deformation recovery force in the direction close to the electrical connection protrusion 120. With the help of the deformation recovery force, the two first rib plates 131 can clamp and limit the insertion part of the electrical connection protrusion 120 and the electrical connection slot, which helps to enhance the locking strength of the electrical connection protrusion 120 and the electrical connection slot in the current insertion state, so that the electrical connection protrusion 120 and the electrical connection slot are inserted into position and firmly.

[0063] The above-mentioned preferred embodiments of the utility model only serve as an example, and do not limit the patent range of the utility model. Any equivalent structural transformation, direct / indirect application in other related technical fields, or the like, which is made according to the utility model specification and the attached drawings, is included in the patent protection range of the utility model.
