DETAILED DESCRIPTION

[0036] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0037] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0038] In each embodiment of the present application, "proximal end" and "distal end" refer to the position of each component relative to the user in the use environment, wherein the end closer to the user is designated as the "proximal end" and the end farther from the user is designated as the "distal end".

[0039] An endoscope is a commonly used medical device used to directly enter the human body's natural cavities for examination, providing doctors with sufficient diagnostic information. An endoscope typically includes an insertion portion for insertion into the human body, a handle for easy operation, and a display device for displaying the internal environment of the human body's natural cavities. The insertion portion and handle are collectively referred to as the operating portion. The operating portion and the display device establish a communication connection via a pluggable plug and socket; the coordination of these three parts enables the endoscope to peer into the human body, explore lesions, and treat them.

[0040] In the prior art, plugs and sockets are typically connected by a snap-fit connection. Unplugging requires applying force to overcome the snap-fitting force. This makes the plug difficult to pull out, and the socket tends to loosen after prolonged use. Furthermore, over time, the reliability of the cable connection decreases significantly, shortening the cable's lifespan.

[0041] In order to solve the above technical problems, the present application embodiment provides a plug 100, please refer to Figure 1 The plug 100 may include a plug connector 110 , a housing 120 and a driving member 130 . The housing 120 is sleeved on the plug connector 110 and slidably fits with the plug connector 110 , and the driving member 130 is connected to the plug connector 110 .

[0042] Please continue reading Figure 1 as well as Figure 2 The connector 110 has a mounting end 110a and an insertion end 110b that are spaced apart from each other. The mounting end 110a is used to mount a cable, and the insertion end 110b is used to insert into the socket 200 and electrically connect. Exemplarily, the connector 110 includes, but is not limited to, one or more pins. One end of the pin is used to mount a cable and transmit a signal or current to the pin through the cable. The end of the pin away from the mounting end 110a extends to the insertion end 110b, which is used to insert into the socket 200. The pins of the connector 110 can be electrically connected to the pins of the socket 200, thereby achieving signal transmission or power supply.

[0043] The cable may be an optical fiber or an electric wire or a combination thereof, for example, the cable may be a combination of electric wire and optical fiber, and the connector 110 is correspondingly provided with a pin needle and an optical fiber pin, which is not limited in this embodiment.

[0044] Please continue reading Figure 1The connector 110 may be provided with a snap-fitting portion 111. The protruding snap-fitting portion 111 facilitates snapping with other components. More specifically, the snap-fitting portion 111 has an inclined surface, the thickness of which gradually increases from the insertion end 110b to the mounting end 110a. This inclined surface not only serves as a guide for the mating of other components, but also makes it easier to accommodate minor deformations during assembly, reduces assembly resistance, and makes the assembly process smoother.

[0045] Please also refer to Figure 2 as well as Figure 3 The housing 120 has a mounting hole 121 corresponding to the snap-fit portion 111. For example, the diameter and shape of the mounting hole 121 can be configured to correspond to the snap-fit portion 111. The snap-fit portion 111 extends into the mounting hole 121 to form a first snap-fit assembly 140. In other words, the mounting hole 121 and the snap-fit portion 111 combine to form the first snap-fit assembly 140. The first snap-fit assembly 140 is configured to snap-fit with the second snap-fit assembly 210 of the socket 200. The first snap-fit assembly 140 can cooperate with the second snap-fit assembly 210 of the socket 200 to snap-fit and secure the plug 100 and the socket 200.

[0046] Among them, see Figure 4 The mounting hole 121 has a first area 121a and a second area 121b that are interconnected. Exemplarily, the first area 121a is located on a side of the second area 121b close to the insertion end 110b. This embodiment does not limit the volume ratio and shape of the first area 121a and the second area 121b.

[0047] See also Figure 2 as well as Figure 4 The driving member 130 is connected to the mounting end 110a of the plug connector 110, and the driving member 130 is used to drive the plug connector 110 to move between the first position and the second position. The first position and the second position are along the insertion direction of the plug 100 (eg Figure 2 ) are distributed in sequence. Relative to the housing 120, the driving member 130 can drive the connector 110 to move along the insertion direction or the removal direction of the plug 100. The insertion direction and the removal direction are opposite. When the connector 110 moves from the first position to the second position, the snap connection between the first snap assembly 140 and the second snap assembly 210 is released. The driving member 130 can drive the connector 110 to slide relative to the housing 120, and release the snap connection between the first snap assembly 140 and the second snap assembly 210 during the sliding process of the connector 110, so as to facilitate the subsequent removal of the plug 100 from the socket 200. The removal method is easier and will not damage its own structure and cable. The reliability and service life of the cable connection are significantly increased.

[0048] It is understood that the connector 110 and the drive member 130 have a certain limiting effect on the housing 120. For example, the connector 110 and the drive member 130 combine to form a certain limiting space, which is used to allow at least a portion of the housing 120 to slide relative to each other. This arrangement can prevent the housing 120 from sliding excessively and causing the plug 100 to disassemble. Therefore, this arrangement can limit the relative sliding of the connector 110 and the housing 120 within a specified path, and the first position and the second position are located within this path.

[0049] In this example, see Figure 5 The plug connector 110 may include a base shell 112, a connection seat 113, and a tail tube 114. The connection seat 113 is provided with one or more pins, and the buckle portion 111 is provided on the base shell 112. The tail tube 114 has a first through hole 1141 for the cable to pass through. The first through hole 1141 allows the cable to pass through the tail tube 114 smoothly. One end of the connection seat 113 is inserted into the base shell 112, and the other end abuts against the tail tube 114 and is electrically connected to the cable inserted into the first through hole 1141, so that the cable inserted into the first through hole 1141 can be electrically connected to the pins, ensuring smooth transmission of current in the plug 100. The driving member 130 is connected to the base shell 112 and is sleeved on the tail tube 114. This arrangement not only ensures the stability of the tail tube 114, but also enables the driving member 130 to effectively constrain and fix the tail tube 114, so that it can fix the cable.

[0050] More specifically, see Figure 6 , the base shell 112 is provided with a second through hole 1121. In other words, the base shell 112 forms an installation cavity 1122, the connecting seat 113 is installed in the installation cavity 1122, and the second through hole 1121 penetrates to form the cavity wall of the installation cavity 1122. The snap-fit portion 111 may include a snap-fit block 111a and an elastic arm 111b, and the snap-fit block 111a cooperates with the installation hole 121. One end of the snap-fit block 111a away from the elastic arm 111b extends into the installation hole 121 of the outer shell 120. Through this arrangement, the connection between the base shell 112 and the outer shell 120 can become more secure, and it is also convenient for disassembly and maintenance. The snap-fit block 111a is located in the second through hole 1121, one end of the elastic arm 111b is connected to the snap-fit block 111a, and the other end is connected to the hole wall of the second through hole 1121. The elastic arm 111b has a certain elasticity. The deformed elastic arm 111b can change the positional relationship between the snap-fit block 111a and the connecting seat 113, so as to change the connection relationship between the snap-fit portion 111 and the second snap-fit component 210 of the socket 200, thereby unlocking or limiting the first snap-fit component 140 and the second snap-fit component 210.

[0051] In one embodiment, see Figure 6The elastic arm 111b may include a first connecting segment 1111, a second connecting segment 1112, and an intermediate segment 1113. The intermediate segment 1113 is connected between the first connecting segment 1111 and the second connecting segment 1112. The end of the first connecting segment 1111 away from the intermediate segment 1113 is connected to the buckle block 111a, and the end of the second connecting segment 1112 away from the intermediate segment 1113 is connected to the hole wall of the second through hole 1121. The cross-sectional area of the intermediate segment 1113 is smaller than that of the first connecting segment 1111 and the second connecting segment 1112. Under the action of the same magnitude of force, the deformation of the intermediate segment 1113 with a smaller area is greater than that of the first connecting segment 1111 and the second connecting segment 1112, further improving the elastic performance of the elastic arm 111b, thereby increasing the displacement of the buckle block 111a and ensuring the normal operation of the connector 110.

[0052] like Figure 2 As shown, the number of the second through holes 1121 can be multiple, such as 2, 3, etc., which is not limited in this embodiment. And the multiple second through holes 1121 are spaced apart from each other. For example, the multiple second through holes 1121 are all opened in the shell 120, and the multiple second through holes 1121 are distributed along the circumference of the shell 120. Figure 6 As shown, the number of snap-fitting portions 111 is multiple, for example, two, three, etc., but this embodiment is not limited thereto. The multiple second through-holes 1121 correspond one-to-one with the multiple snap-fitting portions 111. The interplay of the second through-holes 1121 and the snap-fitting portions 111 can enhance the connection between the first and second snap-fitting components, prevent stress concentration on a single snap-fitting portion 111, and improve the safety of plug 100.

[0053] Please refer again Figure 2 During the installation or removal of the plug 100, the snap-fitting portion 111 will be deformed, and the deformed snap-fitting portion 111 may be separated from the shell 120, causing the plug 100 to disintegrate. Preferably, the distance between the shell 120 and the connecting seat 113 in this embodiment is less than the thickness of the snap-fitting portion 111. The thickness of the snap-fitting portion 111 can be understood as the dimension of the snap-fitting portion 111 along the radial direction of the base shell 112. In other words, the snap-fitting portion 111 is driven to deform, but it cannot be fully accommodated in the gap between the shell 120 and the connecting seat 113. Therefore, the connecting seat 113 will hinder the snap-fitting portion 111, preventing the deformed snap-fitting portion 111 from separating from the shell 120, thereby improving the structural stability of the plug 100.

[0054] It is understood that during the assembly of the plug 100, the connection base 113 will also block the snap-fit portion 111, preventing the base shell 112 from entering the outer shell 120. In this embodiment, the installer can prioritize assembling the base shell 112 into the outer shell 120. At this point, the connection base 113 is not connected to the base shell 112. This allows the installer to easily install the base shell 112 into the outer shell 120 and extend the snap-fit portion 111 into the mounting hole 121. The snap-fit portion 111 will not interfere with the subsequent installation of the connection base 113. Furthermore, the installer sequentially inserts the connection base 113 and tail pipe 114, and connects the driver 130 to the base shell 112 to complete the assembly of the plug 100.

[0055] In one embodiment, see Figure 2 , the buckle portion 111 extends out of the mounting hole 121 and extends toward the outside of the housing 120. In other words, the buckle portion 111 can be inserted into the mounting hole 121 from one side and extended from the other side, thereby protruding from the housing 120. Figure 7 As shown, the snap-fit portion 111 is configured to engage with the retaining hole 211 of the second snap-fit assembly 210, thereby securing the first snap-fit assembly 140 and the second snap-fit assembly 210. The second snap-fit assembly 210 may be a slot or hole, for example. When the plug 100 is inserted into the receptacle 200, the snap-fit portion 111 protruding from the housing 120 engages with the second snap-fit assembly 210, securing the two components, and securing the plug 100 and the receptacle 200.

[0056] When the connector 110 moves from the first position to the second position, the snap-fit portion 111 is received within the mounting hole 121 of the housing 120, releasing the snap-fit connection between the first snap-fit assembly 140 and the second snap-fit assembly 210. Exemplarily, the snap-fit portion 111 abuts against the inner wall of the housing 120. During the movement of the connector 110 from the first position to the second position, the housing 120 forces the snap-fit portion 111 to deform, causing the deformed snap-fit portion 111 to be received within the mounting hole 121, thereby releasing the positional engagement between the snap-fit portion 111 and the second snap-fit assembly 210. Furthermore, the snap-fit connection between the first snap-fit assembly 140 and the second snap-fit assembly 210 is released during the sliding movement of the connector 110. Subsequently, the installer can grasp the connector 110 and the housing 120 and remove them both from the socket 200.

[0057] In addition, in some other cases, the installer can directly pull out the shell 120. During this process, the shell 120 can also force the buckle part 111 to deform, and the deformed buckle part 111 is received in the mounting hole 121, thereby releasing the limiting fit between the buckle part 111 and the second snap-fit assembly 210.

[0058] In another embodiment, see Figure 4 as well as Figure 8 The second clamping assembly 210 is protruded from the inner wall of the socket housing 230 of the socket 200. Figure 9 As shown, the snap-fit portion 111 extends into the first region 121a of the mounting hole 121, thereby achieving a position-limited connection between the snap-fit portion 111 and the housing 120. The second region 121b of the mounting hole 121 is used to accommodate and position-limit the second snap-fit assembly 210. When the plug 100 is snap-fitted to the receptacle 200 and the connector 110 is in the first position, the second snap-fit assembly 210 engages with the mounting hole 121 to achieve a snap-fit connection between the first snap-fit assembly 140 and the second snap-fit assembly 210, thereby securing the plug 100 and the receptacle 200.

[0059] Subsequently, when the plug connector 110 moves from the first position to the second position, the snap-fit portion 111 moves from the first region 121a to the second region 121b and pushes away from the second snap-fit assembly 210 of the socket 200 to the outside of the mounting hole 121, releasing the snap-fit connection between the first snap-fit assembly 140 and the second snap-fit assembly 210. This releases the snap-fit connection between the first snap-fit assembly 140 and the second snap-fit assembly 210, thereby unlocking the first snap-fit assembly 140 and the second snap-fit assembly 210. Subsequently, the installer can grasp the plug connector 110 and the housing 120 and remove them both from the socket 200. During the installation and removal process of the plug 100, the snap-fit portion 111 of the plug connector 110 does not directly deform, reducing fatigue of the snap-fit portion 111 and thereby increasing the service life of the plug 100.

[0060] In another embodiment, please refer to Figure 6 The buckle part 111 is provided with a clearance groove 1114, the opening of which faces the insertion direction of the plug 100. The second clamping assembly 210 may include a driven portion 212 and a limiting block 213. The clearance groove 1114 is used to give way to the limiting block 213 of the second clamping assembly 210, and the buckle part 111 is used to drive the driven portion 212 of the second clamping assembly 210. In other words, Figure 10 As shown, in the second clamping assembly 210, the driven portion 212 and the limiting block 213 are connected to each other. Figure 11 As shown, the clearance groove 1114 is configured to correspond to the stopper 213 of the second snap-fit assembly 210, and the snap-fit portion 111 is configured to correspond to the driven portion 212 of the second snap-fit assembly 210. When the plug 100 is snap-fitted to the receptacle 200 and the connector 110 is in the first position, the stopper 213 engages with the mounting hole 121 to achieve a snap-fit connection between the first snap-fit assembly 140 and the second snap-fit assembly 210, thereby snap-fitting and securing the plug 100 and receptacle 200.

[0061] Subsequently, when the connector 110 moves from the first position to the second position, the snap-fit portion 111 pushes the driven portion 212 away from the mounting hole 121, and the driven portion 212 simultaneously drives the limit block 213 to move outside the mounting hole 121, thereby releasing the snap connection between the first snap-fit assembly 140 and the second snap-fit assembly 210. Thus, the snap connection between the first snap-fit assembly 140 and the second snap-fit assembly 210 is released, thereby unlocking the first snap-fit assembly 140 and the second snap-fit assembly 210. In the subsequent process, the installer can hold the connector 110 and the housing 120 and pull them out of the socket 200 together. The snap-fit portion 111 indirectly drives the limit block 213 for limiting. This arrangement can not only improve the driving effect of the snap-fit portion 111, but also reduce the wear of the limit block 213 of the socket 200, thereby ensuring the reliability of the limit block 213.

[0062] In this example, please refer to Figure 5 , the tail pipe 114 may include a convergence portion 1142, and the convergence portion 1142 abuts against the driving member 130. When the driving member 130 is connected to the connecting seat 113, the driving member 130 can synchronously drive the convergence portion 1142. The convergence portion 1142 is used to accept the drive of the driving member 130 and tighten in the radial direction to clamp the cable inserted into the first through hole 1141. The convergence portion 1142 can accept the driving action from the driving member 130 and can perform an effective tightening action in the radial direction. The purpose of this tightening action is to firmly clamp and fix the cable inserted into the first through hole 1141, ensuring that the cable will not easily loosen or fall off during use, thereby improving the overall stability and reliability.

[0063] In this example, please continue to refer to Figure 5 Tail pipe 114 is provided with a first positioning block 1143. The extension direction of the first positioning block 1143 is parallel to the axial direction of the tail pipe 114, ensuring its precise alignment during installation. The base shell 112 is provided with a first positioning groove 1123, and the connecting seat 113 is provided with a second positioning groove 1131. The first positioning block 1143, the first positioning groove 1123, and the second positioning groove 1131 cooperate with each other. The first positioning block 1143 is inserted into the first positioning groove 1123 and the second positioning groove 1131 to form a stable mating relationship with the first positioning block 1143 and the first positioning groove 1123. When the first positioning block 1143 is inserted into the first positioning groove 1123 and the second positioning groove 1131, the overall stability of the plug connector 110 is significantly improved, ensuring the reliability and durability of the plug connector 110 in practical applications.

[0064] See also Figure 3 as well as Figure 4The outer shell 120 is provided with a third positioning groove 122 and a third positioning block 123. The third positioning groove 122 has a certain guiding function. The base shell 112 is provided with a second positioning block 1124. The extension direction of the second positioning block 1124 is parallel to the axial direction of the base shell 112. The second positioning block 1124 is arranged corresponding to the third positioning groove 122. The second positioning block 1124 is inserted into the third positioning groove 122. This arrangement can complete the assembly and positioning between the outer shell 120 and the base shell 112. The extension direction of the second positioning block 1124 is consistent with the axial direction of the base shell 112, ensuring that the plug 100 is accurately inserted into the socket 200, and the plug 100 and the socket 200 can be stably electrically connected.

[0065] The third positioning block 123 is inserted into the fourth positioning groove 220 of the socket 200. The third positioning block 123 is designed to mate with the fourth positioning groove 220 of the socket 200. Together with the third positioning groove 122 and the third positioning block 123, this ensures a more stable and precise positioning of the plug 100 and the socket 200 during connection. This multi-layered positioning design simplifies and makes the assembly of the plug 100 more reliable, improving its overall performance and service life.

[0066] See also Figure 12 , which is a socket 200 shown in another exemplary embodiment of the present application. The socket 200 is used to be plugged into the aforementioned plug 100. The socket 200 can be electrically connected to the plug 100 to transmit signals or current.

[0067] The socket 200 may include a socket housing 230 and a socket connector 240, which is mounted within the socket housing 230. More specifically, the socket housing 230 is provided with a second snap-fit assembly 210, which is configured to snap-fit with the first snap-fit assembly 140 of the plug 100. The socket connector 240 is configured to electrically connect to the plug connector 110. When the socket connector 240 is electrically connected to the plug connector 110, the second snap-fit assembly 210 of the socket 200 snaps into engagement with the first snap-fit assembly 140 of the plug 100.

[0068] See also Figure 13 , which is another exemplary embodiment of the present application, shows an endoscope 300, which includes an operating portion 310 and the aforementioned plug 100, and a cable connected to the operating portion 310 is electrically connected to the connector 110 of the aforementioned plug 100.

[0069] The plug 100, the socket 200, and the endoscope 300 provided in this embodiment are characterized by a connector 110 that can be inserted into the socket 200 and electrically connected thereto. The snap-fit portion 111 of the connector 110 and the mounting hole 121 of the housing 120 form a first snap-fit assembly 140. The first snap-fit assembly 140 can cooperate with the second snap-fit assembly 210 of the socket 200 to snap-fit and fix the plug 100 and the socket 200. The driving member 130 can drive the connector 110 to slide relative to the housing 120, and release the snap-fit connection between the first snap-fit assembly 140 and the second snap-fit assembly 210 during the sliding process of the connector 110, so as to facilitate the subsequent removal of the plug 100 from the socket 200. The removal method is easier and does not damage its own structure and the cable structure, thereby significantly increasing the reliability and service life of the cable connection.
