Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0042] See also Figures 1 to 10 The present invention provides a re-pluggable electrical connector and an endoscope system used therein. For ease of understanding, in the following embodiments, the endoscope system as a whole is described as having vertical, horizontal and longitudinal directions arranged in pairs. In specific applications, the vertical direction may correspond to the direction of gravity, with an upward direction and a downward direction arranged relatively.

[0043] Specifically, see Figures 1 to 3 The re-pluggable electrical connector provided by the present invention comprises an electrical connection plug 100, an electrical connection socket 200 and a protective structure. The electrical connection plug 100 comprises a first shell 110 and an electrical connection protrusion 120 protruding from one end of the first shell 110; the electrical connection socket 200 comprises a second shell 210 and a circuit board assembly arranged in the second shell 210, the circuit board assembly is arranged in the second shell 210, and comprises a circuit board body 220 and a protrusion 230 protruding from the circuit board body 220, and an electrical connection slot 232a is arranged on one side of the protrusion 230; the protective structure is arranged on the first shell 110 and / or the second shell 210, and in the process of the electrical connection protrusion 120 and the electrical connection slot 232a being plugged in, the protective structure is at least arranged on the side of the electrical connection slot 232a facing away from the circuit board body 220.

[0044] In the technical solution provided by the present invention, during the process of multiple plugging and unplugging between the electrical connection protrusion 120 and the electrical connection slot 232a, the electrical connection protrusion 120 may be skewed relative to the insertion direction of the electrical connection slot 232a, causing the electrical connection protrusion 120 to drive the protrusion 230 to tilt in the direction away from the circuit board body 220; and the present invention provides a protective structure on the side of the electrical connection slot 232a facing away from the circuit board body 220. On the one hand, the protective structure can effectively block the electrical connection protrusion 120 from tilting the protrusion 230 by virtue of the relatively stable connection relationship between the protective structure and the first shell 110 and / or the second shell 210, thereby helping to ensure good electrical plugging between the electrical connection protrusion 120 and the electrical connection slot 232a; on the other hand, the protective structure can form a shield on the outside of the electrical connection slot 232a, and then play a certain auxiliary reinforcement role in terms of waterproofing, dustproofing, shielding, etc., which helps to improve the overall reliability of the electrical connection plug 100 and the electrical connection socket 200 during repeated plugging and unplugging.

[0045] In view of the above, it can be known that when the protective structure is disposed at the first housing 110, when the electrical connection protrusion 120 and the electrical connection slot 232a are not plugged in, the protective structure mainly acts on the electrical connection protrusion 120. Only during the plugging process of the electrical connection protrusion 120 and the electrical connection slot 232a, the protective structure is driven to move to the side of the electrical connection slot 232a facing away from the circuit board body 220, and acts at least on the side of the electrical connection slot 232a facing away from the circuit board body 220.

[0046] When the protective structure is arranged at the second shell body 210, when the electrical connection protrusion 120 and the electrical connection slot 232a are not plugged in, the protective structure has been arranged on the side of the electrical connection slot 232a facing away from the circuit board body 220; and then during the plugging process of the electrical connection protrusion 120 and the electrical connection slot 232a, the protective structure plays its protective role on the side of the electrical connection slot 232a facing away from the circuit board body 220.

[0047] In addition, the protective structure is arranged on the side of the electrical connection slot 232a facing away from the circuit board body 220. Specifically, the protective structure can be arranged inside the protrusion 230, but located on the side of the electrical connection slot 232a facing away from the circuit board body 220; or the protective structure can be directly arranged outside the protrusion 230 and located on the side of the protrusion 230 facing away from the circuit board body 220.

[0048] In view of the above, first, when the protective structure is provided at the first housing 110, the protective structure can be specifically a convex rib 130. The convex rib 130 is provided protrudingly on the first end plate 111, and is spaced apart on one side of the electrical connection protrusion 120 in at least one dimension direction thereof, and in the dimension direction, the orthographic projection area of ​​the convex rib 130 is at least partially overlapped with the orthographic projection area of ​​the electrical connection protrusion 120. When the electrical connection protrusion 120 is in a non-plugged state, the setting of the rib 130 can shield and protect the electrical connection protrusion 120 in at least one dimensional direction of the electrical connection protrusion 120, so that when subjected to an external force applied along the dimensional direction, the rib 130 can effectively prevent the external force from damaging the electrical connection protrusion 120; and the rib 130 can also effectively prevent the external environment from polluting the electrical connection protrusion 120 in the dimensional direction, thereby ensuring that the electrical performance of the electrical connection protrusion 120 is always maintained in an optimal state; when the electrical connection protrusion 120 is plugged into the electrical connection slot 232a in the matching electrical connection socket 200, the rib 130 can also effectively block and protect the plug-in portion of the two, avoiding abnormal deformation of the plug-in portion of the two in the dimensional direction, and ensuring that external foreign matter is difficult to enter the plug-in portion of the two from the dimensional direction, thereby ultimately helping to improve the plug-in quality of the electrical connection plug 100 and the electrical connection socket 200.

[0049] Please combine Figures 4 to 6 The electrical connection plug 100 extends approximately in the longitudinal direction and includes a first housing 110 and a connection cable connected in sequence in the longitudinal direction. One section of the connection cable is inserted and connected in the first housing 110, and the other section extends to connect with a machine body. The shell wall of the first housing 110 at one end away from the connection cable in the longitudinal direction constitutes a first end plate 111, and the first end plate 111 can specifically extend in the vertical direction and the horizontal direction respectively.

[0050] It can be understood that the electrical connection plug 100 is used in conjunction with the electrical connection socket 200. The electrical connection socket 200 includes a second shell 210, and the electrical connection socket 200 defines an electrical connection slot 232a. The electrical connection slot 232a is plugged and unplugged with the electrical connection protrusion 120. At this time, in order to achieve a tight connection during the repeated plugging and unplugging process of the electrical connection slot 232a and the electrical connection protrusion 120, in a specific application, a buckle can be provided on one of the first shell 110 and the second shell 210, and a buckle hole can be provided on the other. When the electrical connection slot 232a and the electrical connection protrusion 120 are plugged in place, the buckle and the buckle hole are buckled and fixed, and the electrical connection slot 232a and the electrical connection protrusion 120 are locked in the current plugged in state.

[0051] Specifically, one section of the electrical connection protrusion 120 is housed in the first housing 110 and connected to the connecting cable. Another section of the electrical connection protrusion 120 passes through the first end plate 111 and protrudes in the longitudinal direction. It is understood that the specific form of the electrical connection protrusion 120 is not limited, for example Figures 4 to 6 As shown, it can be roughly extended in the transverse direction to be in the shape of a plate or a sheet.

[0052] The dimension direction of the electrical connection protrusion 120 mentioned above refers to the length direction, width direction, thickness direction, etc. of the electrical connection protrusion 120. Specifically, when used in the electrical connection plug 100, the dimension direction of the electrical connection protrusion 120 includes the above-mentioned horizontal, longitudinal and vertical directions. The rib 130 can be selectively arranged on any side of the electrical connection protrusion 120 in the horizontal, longitudinal and / or vertical directions, and the rib 130 functions in this direction. The rib 130 is spaced apart from the electrical connection protrusion 120, so as to form a avoidance at the space, so that the electrical connection protrusion 120 and the electrical connection slot 232a can be smoothly plugged in and out.

[0053] Specifically, the convex rib 130 can firstly shield and protect the electrical connection protrusion 120. In particular, when the electrical connection plug 100 is in an idle state, that is, not plugged into the electrical connection socket 200, the convex rib 130 can effectively protect the electrical connection protrusion 120, prevent the electrical connection protrusion 120 from being damaged by external impact, and prevent the electrical connection protrusion 120 from being contaminated by external environment, such as impurities, water vapor, sweat stains caused by operators when grasping, etc.

[0054] Next, if the second housing 210 or other structure in the electrical connection socket 200 is preset with an escape space at the position corresponding to the convex rib 130, then when the electrical connection plug 100 and the electrical connection socket 200 are used together, and the electrical connection protrusion 120 and the electrical connection slot 232a are plugged in, the escape space can accommodate the convex rib 130. At this time, the convex rib 130 is located beside the plugging position of the electrical connection protrusion 120 and the electrical connection slot 232a, and can simultaneously play a role in strengthening and protecting the structure of the plugging position of the electrical connection protrusion 120 and the electrical connection slot 232a. The structural strengthening effect can be specifically, for example, through the mutual contact between the convex rib 130 and other components at the escape space, the plugging strength of the electrical connection protrusion 120 and the electrical connection slot 232a can be strengthened.

[0055] Furthermore, if the above-mentioned avoidance space is specifically set as a guide groove that can be slidably connected or roll-connected with the rib 130, then when the electrical connection plug 100 is used in conjunction with the electrical connection socket 200, the electrical connection protrusion 120 and the electrical connection slot 232a are driven to be plugged in. Through the sliding connection or rolling connection between the rib 130 and the guide groove, the plugging process of the electrical connection protrusion 120 and the electrical connection slot 232a can be accurately guided, and the plugging direction of the electrical connection protrusion 120 and the electrical connection slot 232a can be limited to a certain extent, thereby avoiding structural damage to the electrical connection protrusion 120 or the electrical connection slot 232a due to the deviation of the plugging direction during the plugging process.

[0056] In view of the above, the protruding height of the rib 130 determines to a certain extent the effective area of ​​the rib 130 on the electrical connection protrusion 120 in the corresponding dimension direction, such as the shielding area. Therefore, in this embodiment, in order to achieve complete shielding of the electrical connection protrusion 120 in the dimension direction as much as possible, the protruding height of the rib 130 relative to the first end plate 111 can be set to be not less than the protruding height of the electrical connection protrusion 120. Figures 4 to 6 As shown, the protruding height of the rib 130 can be substantially the same as the protruding height of the electrical connection protrusion 120, that is, the rib 130 can completely cover the electrical connection protrusion 120, and the free end surface of the rib 130 is substantially flush with the free end surface of the electrical connection protrusion 120, which helps to save material for the rib 130.

[0057] Of course, according to actual needs, in other applications, the protruding height of the rib 130 can be specifically set to be greater than the protruding height of the electrical connection protrusion 120, so that the rib 130 can completely cover the electrical connection protrusion 120 while also forming a certain extended rib segment. The extended rib segment can play other roles according to actual needs. For example, when a guide groove is preset as described above, the extended rib segment can make the movable matching surface between the rib 130 and the guide groove larger, which helps to optimize the guiding effect.

[0058] It should be noted that the rib 130 and the first end plate 111 can be integrally formed, or can be separately formed and then connected in a detachable or non-detachable manner. The detachable connection is, for example, one or more of the following methods: screw fixation, snap fixation, adhesive fixation, adsorption fixation, etc. The non-detachable connection is, for example, welding fixation, thermal compression fixation, etc.

[0059] Based on one or more of the above embodiments, the convex rib 130 may be provided as one or more in only one dimension direction of the electrical connection protrusion 120 ; or, the convex rib 130 may be provided as one or more in at least two dimension directions of the electrical connection protrusion 120 .

[0060] Specifically, in one embodiment, the electrical connection protrusion 120 has a first dimension direction and a second dimension direction that are arranged crosswise. The first dimension direction is, for example, Figures 4 to 6 In the horizontal direction, the second dimension direction is, for example, Figures 4 to 6In the vertical direction. At this time, the convex rib 130 may 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 protrusion 120 in the first dimension direction, and extends along the second dimension direction. In the first dimension direction, the orthographic projection area of ​​the first rib plate 131 is at least partially overlapped with the orthographic projection area of ​​the electrical connection protrusion 120, which can at least play the above-mentioned shielding and protection role for the electrical connection protrusion 120 in the first dimension direction; the second rib plate 132 is located on one side of the electrical connection protrusion 120 in the second dimension direction, and extends along the first dimension direction, and the second rib plate 132 is connected to the first rib plate 131. Specifically, in the second dimensional direction, the orthographic projection area of ​​the second rib 132 can be set to at least partially overlap with the orthographic projection area of ​​the electrical connection protrusion 120, so as to shield and protect the electrical connection protrusion 120 in the second dimensional direction; or, the orthographic projection area of ​​the second rib 132 can be set to be staggered with the orthographic projection area of ​​the electrical connection protrusion 120, so that the second rib 132 only plays a guiding role such as mentioned above, and at the same time, the structural strength of the first rib 131 can be strengthened with the help of the second rib 132.

[0061] The first rib plate 131 and the second rib plate 132 as described above can also be integrally formed, or can be separately formed and then connected in a detachable or non-detachable manner. The detachable connection can be, for example, one or more of the following methods: screwing, snapping, bonding, adsorption, etc. The non-detachable connection can be, for example, welding, hot pressing, etc.

[0062] Since the first dimension direction roughly corresponds to the horizontal direction, and the second dimension direction roughly corresponds to the vertical direction, the two are roughly perpendicular, that is, the first rib plate 131 and the second rib plate 132 are roughly perpendicular, forming an angle of about 90°. At this time, the connection between the first rib plate 131 and the second rib plate 132 can be made to have a smooth transition, for example, a circular chamfer is made at the connection between the two, or a straight inclined transition connection is made at the connection between the two, so as to avoid forming a sharp structure at the connection between the two.

[0063] The first rib plate 131 and the second rib plate 132 can be arranged in a group on one side of the electrical connection protrusion 120 in the first dimension direction, or in one embodiment, two first rib plates 131 are provided, and the two first rib plates 131 are respectively provided on the opposite sides of the electrical connection protrusion 120 in the first dimension direction. In this case, the second rib plates 132 can be provided in two corresponding to the two first rib plates 131; or the second rib plate 132 is provided as one, and the second rib plate 132 extends along the first dimension direction to connect with the two first rib plates 131.

[0064] Next, the first rib 131 is generally configured to be connected and fixed to the first end plate 111, which can be specifically integrally formed as described above, or a detachable connection or a non-detachable connection after split molding. At this time, the second rib 132 can also be configured to be connected and fixed to the first end plate 111, or it can be selected to be connected and fixed only to the two first ribs 131, while maintaining a gap with the first end plate 111. A first visual window is formed at the gap between the second rib 132 and the first end plate 111. The first visual window is closer to the connection between the electrical connection protrusion 120 and the first end plate 111, and this part of the electrical connection protrusion 120 can be visually checked to confirm that it is in a relatively good installation state; or the connection between the electrical connection protrusion 120 and the first end plate 111 can be cleaned based on the first visual window.

[0065] Of course, when the second rib 132 is also connected and fixed to the first end plate 111, or the aperture of the above-mentioned first visible window is small, further, in one embodiment, the second rib 132 is provided with a through hole 132a along the second dimension direction, and in the second dimension direction, the orthographic projection area of ​​the through hole 132a is at least partially overlapped with the orthographic projection area of ​​the electrical connection protrusion 120. At this time, the connection and fixation of the second rib 132 and the first end plate 111 helps to enhance the structural strength of the second rib 132. The setting of the through hole 132a is equivalent to forming a second visible window. The through hole 132a is opposite to at least a part of the electrical connection protrusion 120, and the structural state and installation state of the electrical connection protrusion 120 can be viewed based on the through hole 132a, and operations such as cleaning and wiping can be performed on the electrical connection protrusion 120 based on the through hole 132a.

[0066] Furthermore, the through hole 132a is provided at a portion of the second rib plate 132 away from the first end plate 111. That is, the through hole 132a is sufficiently close to the free end of the electrical connection protrusion 120. In this way, on the one hand, it can be ensured that the second rib plate 132 reserves enough plate surface to be connected and fixed with the first end plate 111; on the other hand, it can be ensured that the second rib plate 132 can at least focus on shielding and protecting the connection between the electrical connection protrusion 120 and the first end plate 111 in the second dimension direction. In addition, the second visible window defined by the through hole 132a can only be for a section of the electrical connection protrusion 120 close to its free end, which does not affect the visual viewing effect, and also limits the cleaning and wiping area to a certain extent, avoiding the cleaning and wiping operation from affecting the installation between the electrical connection protrusion 120 and the first end plate 111. In actual application, the through hole 132a can specifically pass through the end of the second rib plate 132 away from the first end plate 111.

[0067] In addition, it should be noted that when the guide grooves are provided at the second housing 210 of the electrical connection socket 200 as described above, the guide grooves include a first guide groove corresponding to the first rib plate 131 and a second guide groove corresponding to the second rib plate 132. The first guide groove and the second guide groove are connected.

[0068] In view of the above, the first dimension direction corresponds to the length direction of the electrical connection protrusion 120, and the second dimension direction corresponds to the width direction of the electrical connection protrusion 120. In this way, the electrical connection protrusion 120 forms a larger extended plate surface in the first dimension direction, especially when the above-mentioned through hole 132a is opened, so that based on the through hole 132a, almost the entire plate surface of the electrical connection protrusion 120 in the length direction can be visually inspected and cleaned.

[0069] In addition, the rib 130 is generally configured to extend straight along the longitudinal direction. However, this does not constitute a limitation on the specific forms of expression such as the extension direction and extension shape of the rib 130. According to actual needs, the rib 130 can also be configured to have a certain inclination relative to the longitudinal direction, for example, the rib 130 gradually extends in a direction toward the electrical connection protrusion 120 in the direction away from the first end plate 111 in the longitudinal direction, and the rib 130 has a certain elastic deformation ability in the direction close to and away from the electrical connection protrusion 120. As mentioned above, the rib 130 is specifically two first ribs 131 respectively arranged on both sides of the electrical connection protrusion 120. In this way, when the electrical connection plug 100 is in an idle state, the two first ribs 131 are in a natural undeformed state, and their free sections are closer to the electrical connection protrusion 120, which can play a certain role in retracting and protecting the side of the electrical connection protrusion 120 away from the first end plate 111. When the electrical connection plug 100 is plugged into the electrical connection socket 200, the first rib 131 is expanded and deformed in the direction away from the electrical connection protrusion 120 under the guidance of the above-mentioned avoidance space or guide groove. On the one hand, it helps to make way for the electrical connection protrusion 120 and the electrical connection slot 232a to be plugged in smoothly. On the other hand, when the electrical connection protrusion 120 and the electrical connection slot 232a are successfully plugged in, the two first ribs 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 ribs 131 can be clamped and limited to the plug-in position of the electrical connection protrusion 120 and the electrical connection slot 232a, which helps to enhance the locking strength of the electrical connection protrusion 120 and the electrical connection slot 232a in the current plug-in state, so that the electrical connection protrusion 120 and the electrical connection slot 232a are plugged in place and firmly.

[0070] In addition, in one embodiment, the convex rib 130 (including the first rib plate 131 and the second rib plate 132) can be arranged so that when the electrical connection protrusion 120 and the electrical connection slot 232a are plugged together, the first rib plate 131 is sufficiently close to the lateral side wall of the protrusion 230, and the second rib plate 132 is sufficiently close to the side wall of the protrusion 230 that is vertically away from the circuit board body 220. Furthermore, the first rib plate 131 can slide and abut against the lateral side wall of the protrusion 230, and the second rib plate 132 can slide and abut against the side wall of the protrusion 230 that is vertically away from the circuit board body 220. In this way, the convex rib 130 can be directly stopped and limited at the outer side of the protrusion 230 to prevent the protrusion 230 from being driven by the electrical connection protrusion 120 and lifting off the circuit board body 220.

[0071] Of course, in view of one or more of the above embodiments, when the protective structure is arranged at the second housing 210, the protective structure can be specifically a stopper structure 240. The stopper structure 240 is fixedly arranged on the circuit board body 220, and at least the stopper is arranged on the side of the protrusion 230 facing away from the circuit board body 220. By arranging the stopper structure 240 on the side of the protrusion 230 facing away from the circuit board body 220, the electrical connection protrusion 120 can be effectively blocked from tilting the protrusion 230 by means of the stable connection between the stopper structure 240 and the circuit board body 220, thereby helping to ensure good electrical connection between the electrical connection protrusion 120 and the electrical connection slot 232a; in addition, the stopper structure 240 can also form a shield on the outside of the electrical connection slot 232a, and then play a certain auxiliary reinforcement role in, for example, waterproofing, dustproofing, shielding, etc., which helps to improve the reliability of the electrical connection plug 100 and the electrical connection socket 200 in the repeated plugging and unplugging process.

[0072] Please combine Figures 7 to 9 , a mounting cavity is formed inside the second shell 210. The circuit board assembly is at least partially accommodated in the mounting cavity. Specifically, the second shell 210 extends approximately in the longitudinal direction. The shell wall at one longitudinal end of the second shell 210 constitutes a second end plate 211. The second shell 210 also includes a base plate, and the base plate and the second end plate 211 are connected and fixed after being integrally formed, or the base plate and the second end plate 211 are detachably or non-detachably connected and fixed after being separately formed. The base plate extends approximately in the longitudinal and transverse directions. The circuit board body 220 in the circuit board assembly also extends approximately in the longitudinal and transverse directions, and is fixed to the base plate by column feet.

[0073] Among them, one or more column feet may be provided between the bottom plate and the circuit board body 220 to ensure the stable support of the circuit board body 220 at the bottom plate. The column feet can generally be fixed with the bottom plate by integral molding. In this case, a detachable connector may be further provided between the column feet and the circuit board body 220, for example, threaded holes are provided at corresponding parts of the column feet and the circuit board body 220, and then two threaded holes are sequentially connected by a screw connector to achieve the purpose of limiting the circuit board body 220 on the column feet.

[0074] Next, at least one of the two longitudinal sides and the two transverse sides of the circuit board body 220 can abut against the inner wall of the second shell 210, and the lateral position limitation of the circuit board body 220 is realized by the second shell 210. Of course, at least one of the two longitudinal sides and the two transverse sides of the circuit board body 220 can also be spaced from the inner wall of the second shell 210 to form a gap, so that the gap is connected with the space formed between the circuit board body 220 and the bottom plate, forming an annular heat dissipation path for the hot air generated at the circuit board body 220 to circulate.

[0075] The protrusion 230 is accommodated in the second housing 210, and can be specifically arranged on the side of the circuit board body 220 facing away from the bottom plate. It can be understood that the protrusion 230 defines an electrical connection slot 232a. The second end plate 211 is provided with a plug-in channel 211a in the longitudinal direction, and the plug-in channel 211a is connected to the installation cavity of the second housing 210, and is directly opposite to and connected to the notch of the electrical connection slot 232a. In this way, when the electrical connection protrusion 120 in the electrical connection plug 100 used in conjunction with the electrical connection socket 200 moves along the plug-in channel 211a, it can be inserted into the electrical connection slot 232a under the accurate guidance of the plug-in channel 211a.

[0076] Specifically in one embodiment, the protrusion 230 is provided with a mounting groove 231 on one side facing the insertion channel 211a, and the notch of the mounting groove 231 is directly opposite to and connected with the channel opening of the insertion channel 211a. The protrusion 230 is provided with at least two rows of electrical terminals 232 spaced vertically in the mounting groove 231, and each row of electrical terminals 232 extends in the horizontal direction. An electrical connection slot 232a is defined between each two adjacent rows of electrical terminals 232. When the electrical connection protrusion 120 is inserted into the electrical connection slot 232a, the electrical connection protrusion 120 is in contact with the electrical connection terminal 232, completing the electrical connection.

[0077] Furthermore, the bump 230 may be provided with an opening 231a connected to the mounting groove 231 on one side facing the circuit board body 220. The opening 231a allows at least a portion of the electrical terminal 232 to be exposed, so that the electrical terminal 232 can be electrically connected to a preset contact on the circuit board body 220 through the opening 231a.

[0078] The specific form of the projection 230 is not limited. According to actual needs, the projection 230 can present different shapes, sizes and materials. For example, the projection 230 can be directly made of a hard insulating material. Or in one embodiment, the projection 230 can be made of an elastic material as a whole; or at least the portion of the projection 230 where the mounting groove 231 is provided is made of an elastic material. In this way, when the plugging direction of the electrical connection protrusion 120 is deflected and a force is applied to the projection 230, the projection 230 can offset the force applied by the electrical connection protrusion 120 by generating a certain degree of elastic deformation, thereby preventing the projection 230 from being driven by the electrical connection protrusion 120 and moving away from the circuit board body 220 in the vertical direction. In addition, under the action of the electrical connection protrusion 120, the notch of the mounting groove 231 is deformed to expand, which can also assist in guiding the electrical connection protrusion 120 to be inserted into the electrical connection slot 232a.

[0079] Based on one or more of the above embodiments, further, the stop structure 240 is at least arranged on the side of the protrusion 230 facing away from the circuit board body 220. That is, the stop structure 240 is externally disposed on the protrusion 230, and directly stops and limits the protrusion 230 in the vertical direction, so that when the electrical connection protrusion 120 applies a force to the electrical connection slot 232a in the vertical direction away from the circuit board body 220 during the plugging and unplugging process, the stop structure 240 can effectively prevent the protrusion 230 from being driven away from the circuit board body 220, thereby ensuring that the electrical connection between the electrical connection terminal 232 and the circuit board body 220 as described above is stable and effective.

[0080] Specifically, the stop structure 240 can maintain a certain distance from the outer wall of the protrusion 230 in the vertical direction, that is, it does not completely abut the protrusion 230. If a first spacing is formed between the stop structure 240 and the protrusion 230, when the protrusion 230 is driven vertically away from the circuit board body 220 without exceeding the first spacing, the stop structure 240 will not abut the protrusion 230, and it is assumed that the lifting of the protrusion 230 within this range is not enough to destroy the electrical connection between the electrical terminal 232 and the circuit board body 220.

[0081] Specifically in this embodiment, the stop structure 240 can vertically abut against the outer wall of the protrusion 230. In this way, as long as the electrical connection protrusion 120 drives the protrusion 230 to have a vertical stroke away from the circuit board body 220, it can be stopped and limited by the stop structure 240.

[0082] In this design, the stop structure 240 is arranged as close to the notch of the electrical connection slot 232a as possible. In this way, when the electrical connection protrusion 120 is just inserted into the electrical connection slot 232a, the stop structure 240 can play its role of stopping and limiting until the electrical connection protrusion 120 and the electrical connection slot 232a are plugged into place.

[0083] The stopper structure 240 mentioned above can be spaced apart from the second end plate 211, for example, fixedly connected to the above-mentioned bottom plate, or any side plate of the second housing 210. Alternatively, the stopper structure 240 is connected and fixed to the second end plate 211, so that the stopper structure 240 is as close to the notch of the electrical connection slot 232a as possible. Specifically, the stopper structure 240 and the second end plate 211 can be fixed in an integral molding, or can be connected and fixed in a detachable or non-detachable manner after being separately molded.

[0084] Specifically, the stopper structure 240 may be provided as one on the side of the protrusion 230 away from the circuit board body 220. Specifically, when the stopper structure 240 has a first orthographic projection area on the circuit board body 220, and the electrical connection slot 232a has a second orthographic projection area on the circuit board body 220, the first orthographic projection area and the second orthographic projection area at least partially overlap. Specifically, for example, the first orthographic projection area overlaps with the area of ​​the second orthographic projection area close to the second end plate 211, and the overlapping area of ​​the two may reach one-half to two-thirds of the second orthographic projection area.

[0085] Further optionally, the first orthographic projection area can also completely cover the second orthographic projection area, including the first orthographic projection area just covering the second orthographic projection area, or the first orthographic projection area not only covers the second orthographic projection area, but also exceeds the second orthographic projection area. In this way, the stop structure 240 can effectively stop and limit at least in the entire stroke section of the electrical connection protrusion 120 inserted into the electrical connection slot 232a.

[0086] Of course, at least two stop structures 240 may be provided. In this case, the stop structures 240 are arranged in sequence along the longitudinal direction. At least one of the stop structures 240 is arranged as close as possible to the notch of the electrical connection slot 232a, and at least another of the stop structures 240 is arranged as close as possible to the bottom of the slot of the electrical connection slot 232a, and the remaining stop structures 240 may be dispersedly arranged between the two stop structures 240.

[0087] In addition, the above-mentioned stop structure 240 can also be disposed on both lateral sides of the protrusion 230. Figures 7 to 9As shown, in one embodiment, the stop structure 240 includes a first baffle 241 and two second baffles 242. The first baffle 241 is arranged on the side of the protrusion 230 facing away from the circuit board body 220; the two second baffles 242 are arranged on opposite sides of the protrusion 230 corresponding to the slot width direction of the electrical connection slot 232a, and the second baffles 242 are connected to the first baffle 241. The first baffle 241 and the two second baffles 242 are enclosed together to form a U-shape, and the protrusion 230 can be covered at the circuit board body 220. The first baffle 241 and the second baffle 242 can be integrally formed, or they can be separately formed and then connected detachably or non-detachably.

[0088] The second baffle plate 242 mentioned above may extend longitudinally to maintain a gap with the first end plate 111, or extend longitudinally to be connected and fixed with the first end plate 111. Similarly to the above, the connection and fixation between the second baffle plate 242 and the first end plate 111 may be integrally formed, or may be detachably or non-detachably connected and fixed after separate molding.

[0089] The second baffle 242 mentioned above extends vertically to directly contact the circuit board body 220. Alternatively, in one embodiment, the second baffle 242 extends vertically to be spaced apart from the circuit board body 220. In this way, the second baffle 242 does not directly contact the circuit board body 220, which can reduce the burden of the size design of the second baffle 242 and the bump 230 to a certain extent, and can effectively reduce the mutual interference between the second baffle 242 and the circuit board body 220. In this way, the second baffle 242 does not occupy additional board space of the circuit board body 220, so that the circuit board body 220 can reserve enough space for the layout and routing design of the electronic components required.

[0090] Further, when the protrusion 230 is provided with a mounting groove 231 on the side facing the insertion channel 211a as described above, and the protrusion 230 is provided with an opening 231a connected to the mounting groove 231 on the side facing the circuit board body 220, at least two rows of electrical terminals 232 are arranged in the mounting groove 231, and an electrical connection slot 232a is defined between the two rows of electrical terminals 232, and the electrical terminals 232 are electrically connected to the circuit board body 220 through the opening 231a, the spacing between the second baffle 242 and the circuit board body 220 can be specifically designed to be not less than the height of the opening 231a. It can be understood that the protrusion 230 is provided with an opening 231a on the side close to the circuit board body 220 in the vertical direction, so as to facilitate the electrical connection of the electrical terminals 232 with the preset electronic components on the circuit board body 220 through the opening 231a, or to route the wires. In order to make the space for the preset electronic components or wiring on the circuit board body 220 more sufficient, generally, at least one side wall of the protrusion 230 is provided with a notch, and the notch can be connected to the mounting groove 231. The height of the above-mentioned opening 231a is equivalent to the width of the notch in the vertical direction. When the distance between the second baffle 242 and the circuit board body 220 is not less than the height of the opening 231a, the above-mentioned notch can be fully exposed. In this way, on the one hand, the setting of the second baffle 242 does not affect the layout of the preset electronic components or wiring in the circuit board body 220, and on the other hand, the preset electronic components or wiring in the circuit board body 220 are visible, which is convenient for the user to confirm the status of the preset electronic components or wiring in the circuit board body 220 through the distance and the notch.

[0091] In view of the above, it can be understood that the rib 130 and the stop structure 240 can be set at the same re-pluggable electrical connector or at the same time. In the process of plugging the electrical connection protrusion 120 into the electrical connection slot 232a, the first rib plate 131 and the first guide groove, and the second rib plate 132 and the second guide groove are respectively slidably connected or rolled to smoothly guide the electrical connection protrusion 120 to be plugged into the electrical connection slot 232a. At this time, when the electrical connection protrusion 120 exerts a force on the protrusion 230 in the vertical direction away from the circuit board body 220, the first stop plate 241 can stop and limit the protrusion 230 as a whole; when the electrical connection protrusion 120 exerts a force on the protrusion 230 in the horizontal direction, the second stop plate 242 can stop and limit the protrusion 230 as a whole.

[0092] In addition, the stop structure 240 in any of the above embodiments can be made of shielding material, so that when the first baffle 241 and the second baffle 242 in the stop structure 240 cover the outside of the protrusion 230, they can also play their shielding role. At this time, the stop structure 240 can be extended to completely cover the protrusion 230, so as to achieve a better shielding effect.

[0093] Of course, based on any of the above embodiments, the re-pluggable electrical connector further includes a shielding shell 250, which is disposed on the outside of the protrusion 230 and has an escape opening at the notch corresponding to the electrical connection slot 232a. The escape opening can form an escape space without affecting the plugging and unplugging operation of the electrical connection protrusion 120 and the electrical connection slot 232a.

[0094] There is a connection relationship between the shielding shell 250 and the circuit board body 220, between the shielding shell 250 and the protrusion 230, and / or between the shielding shell 250 and the second shell 210. Take the connection and fixation between the shielding shell 250 and the circuit board body 220 as an example. Specifically in one embodiment, one of the shielding shell 250 and the circuit board body 220 is provided with a socket 221, and the other is provided with a leg 251, and the leg 251 is penetrated and welded to the socket 221, and the socket 221 and the leg 251 are correspondingly provided in multiple groups, and each group of the socket 221 and the leg 251 is arranged on opposite sides of the protrusion 230. Fig.10 As shown, at least two jacks 221 may be provided on both lateral sides of the circuit board body 220 located at the protrusion 230, and the jacks 221 on the same side are arranged in sequence along the longitudinal direction. Then, at least two legs 251 may be provided on both lateral sides of the shielding shell 250. During assembly, each leg 251 is plugged into each jack 221 one by one, so that after the leg 251 passes through the corresponding jack 221, it extends outward from the jack 221. Finally, by welding the extended portion of the leg 251, the circuit board body 220, and the gap between the leg 251 and the jack 221, the shielding shell 250 is stably assembled to the circuit board body 220.

[0095] The shielding shell 250 completely covers the areas on both sides of the lateral direction and both sides of the longitudinal direction (except the electrical connection slot 232a) of the protrusion 230, so as to shield the protrusion 230 as completely as possible. The shielding shell 250 can be formed by bending a shielding plate, for example. Of course, the shielding shell 250 can also be formed by at least two shell plates connected in a detachable or non-detachable manner.

[0096] Based on any of the above embodiments of the re-pluggable electrical connector, it can be understood that the endoscope system can include at least two bodies in addition to the re-pluggable electrical connector. Among them, the electrical connection plug 100 and the electrical connection socket 200 are arranged at the two bodies in a one-to-one correspondence. The specific types of the two bodies are not limited, and can be but not limited to: one of the bodies is an endoscope, and the other body is an external control host. By plugging the electrical connection socket 200 and the electrical connection plug 100, the electrical signal communication between the endoscope and the control host can be achieved. Or one of the bodies is an endoscope, and the other body is an external light source device. By plugging the electrical connection socket 200 and the electrical connection plug 100, the light emitted by the external light source device can be guided to the head end structure of the endoscope inserted into the main body through the optical fiber.

[0097] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention.
