Detailed Description

The following description provides many different embodiments, or examples, for implementing different features of the utility model. The elements and arrangements described in the following specific examples are presented for purposes of brevity and are provided only as examples and are not intended to limit the utility model.

In the embodiments of the present application, "proximal" and "distal" refer to the endoscope and its accessories in the use environment, with respect to the user's near-far position, wherein the end closer to the user is designated as "proximal" and the end farther from the user is designated as "distal".

Some embodiments of the present application provide a connector 100 for connection with a handle of an endoscope, the connector 100 including a first snap-in structure 110 and an unlocking mechanism 300 as shown in connection with fig. 1-11. The first clamping structure 110 is movably disposed on the connector 100, and a relative position between the first clamping structure 110 and the connector 100 can be changed, so that the first clamping structure 110 is switched between a first state and a second state. In the case that the first clamping structure 110 is in the first state and the connector 100 is plugged into the mating connector 200 on the host, the first clamping structure 110 is in clamping fit with the second connector 100 of the mating connector 200, so that the connector 100 is firmly connected with the mating connector 200. Under the condition that the first clamping structure 110 is in the second state, and the connector 100 is plugged with the mating connector 200 on the host, the first clamping structure 110 is separated from the second clamping structure 210, the clamping fit between the first clamping structure 110 and the second clamping structure 210 is released, and the second clamping structure 210 cannot prevent the first clamping structure 110 from being pulled out in the process of pulling out the connector 100 from the mating connector 200.

The unlocking mechanism 300 is movably disposed in the connector 100, when the first clamping structure 110 is in the first state, the first clamping structure 110 is located on a moving path of the unlocking mechanism 300, and the unlocking mechanism 300 is configured to be driven by a user to move to push against the first clamping structure 110 in the first state, so as to change the position of the first clamping structure 110, so that the first clamping structure 110 is switched from the first state to the second state.

After the first clamping structure 110 and the second clamping structure 210 are released from the clamping fit, in the process of pulling out the connector 100 from the butt connector 200, the first clamping structure 110 and the second clamping structure 210 are not contacted, the butt connector 200 and the connector 100 are smoothly separated, the first clamping structure 110 cannot damage the second clamping structure 210, the second clamping structure 210 on the host can be maintained intact, and the service life of the host is not affected.

In some alternative embodiments, referring to fig. 2, the connector 100 includes an outer sleeve 160 and an inner connecting body 170, a plurality of signal pins 180 are disposed on the connecting body 170, the signal pins 180 are plugged with the docking connector 200 to implement signal interaction, and the outer sleeve 160 is sleeved outside the connecting body 170 to enclose the plurality of signal pins 180 and protect the signal pins 180. The first locking structure 110 may be disposed on the connecting body 170 or the inner peripheral wall of the outer sleeve 160, and the unlocking mechanism 300 is generally disposed on the outer sleeve 160, so that a user can operate the unlocking mechanism 300 conveniently.

The connector 100 provided in some embodiments of the present application may be used on other electronic devices other than an endoscope, where the electronic device is plugged and matched with other devices through the connector 100. In the process of separating the connector 100 from other devices, the connector 100 is damaged, thereby avoiding damage to other devices.

In some alternative embodiments, the first locking structure 110 is rotatably disposed with the connector 100, and the unlocking mechanism 300 pushes the first locking structure 110 to rotate, so that the first locking structure 110 is switched from the first state to the second state. Specifically, a limiting structure is disposed on the connector 100 to limit the position of the first clamping structure 110, so that under the condition that the first clamping structure 110 is in the first state, the position of the first clamping structure 110 on the connector 100 is stable, the clamping fit of the first clamping structure 110 and the second clamping structure 210 is stable, under the condition that the first clamping structure 110 is in the second state, the first clamping structure 110 cannot return to the first state again, and under the process that the connector 100 is separated from the docking connector 200, the first clamping structure 110 can be in the second state all the time and can be separated from the second clamping structure 210 smoothly.

In other alternative embodiments, the first clamping structure 110 may be slidably connected to the connector 100, and the first clamping structure 110 slides on the connector 100 to change its relative position to the connector 100. The unlocking mechanism 300 pushes the first clamping structure 110 to slide, so that the first clamping structure 110 is switched from the first state to the second state. Specifically, a limiting member 130 is disposed on the sliding path of the first clamping structure 110, where the limiting member 130 is used to stop the first clamping structure 110 at the position where the first clamping structure is in the first state. Under the condition that the unlocking mechanism 300 does not push against the first clamping structure 110, the first clamping structure 110 is in the first state due to the stop of the limiting member 130, and the relative position of the first clamping structure 110 and the connector 100 can be maintained stable, so that the first clamping structure 110 and the second clamping structure 210 are clamped stably. Meanwhile, the limiting component can also stop the first clamping structure 110 in the second state, so as to prevent the first clamping structure 110 from being switched from the second state to the first state.

In the case where the first clamping structure 110 is slidably engaged with the connector 100, there are a plurality of sliding structures of the first clamping structure 110 and the connector 100. In some alternative embodiments, a sliding protrusion is disposed on the connector 100, a corresponding sliding groove is disposed at an end of the first clamping structure 110, the sliding protrusion and the sliding groove are in sliding fit, and the limiting member 130 is disposed on the sliding protrusion to limit the first clamping structure 110. In other alternative embodiments, the connector 100 is provided with a movable cavity 120, and as shown in fig. 6 and 10, the end of the first clamping structure 110 is movably disposed in the movable cavity 120, and the limiting member 130 is disposed on an inner sidewall of the movable cavity 120 to limit the first clamping structure 110. In some embodiments, the first clamping structure 110 may be disposed at an end of the connecting body 170 of the connector 100 or disposed on a side wall of the connecting body 170, and the position of the first clamping structure 110 on the connecting body 170 is not limited in this application.

In some alternative embodiments, the first clamping structure 110 may deform under an external force. One end of the first clamping structure 110 is movably connected with the connector 100, the other end of the first clamping structure 110 extends outwards, the first clamping structure 110 is provided with a clamping part 112, the clamping part 112 is of a protruding structure, the second clamping structure 210 is of a groove structure, and under the condition that the first clamping structure 110 is matched with the second clamping structure 210 in a clamping mode, the first clamping structure 110 needs to be partially deformed to enable the clamping part 112 to be clamped into the groove, so that the clamping matching of the first clamping structure and the second clamping structure is achieved. Moreover, the user drives the unlocking mechanism 300 to move, so that the unlocking mechanism 300 is pushed against the first clamping structure 110 in the first state, and the unlocking mechanism 300 needs to push against the first clamping structure 110 beyond the limiting piece 130 to switch the first clamping structure 110 to the second state because the first clamping structure 110 is limited by the limiting piece 130. In the process of passing over the limiting member 130, the first clamping structure 110 needs to be deformed to pass over the limiting member 130. In addition, the stopper 130 may be configured to be deformed by an external force.

During the sliding process of the unlocking mechanism 300 pushing against the first locking structure 110, care should be taken to avoid the first locking structure 110 from being separated from the connector 100 during the sliding process. In the case that the movable cavity 120 is disposed on the connector 100 and the end portion of the first clamping structure 110 is movably disposed in the movable cavity 120, the inner dimension of the movable cavity 120 is larger than the opening dimension of the movable cavity 120 to limit the position of the first clamping structure 110, as shown in fig. 4 and 5, in fig. 4, the first clamping structure 110 extends out of the movable cavity 120, and in fig. 5, the end portion of the connector 100 is cut into a portion so as to observe the inner structure of the movable cavity 120. Meanwhile, for easy assembly, a mounting port is provided on the connector 100, through which an end of the first clamping structure 110 enters the movable cavity 120.

When the first clamping structure 110 is slidably engaged with the connector 100, the sliding direction of the first clamping structure 110 may have various situations. In some embodiments, the sliding direction of the first clamping structure 110 may be parallel to the moving direction of the unlocking mechanism 300. When the unlocking mechanism 300 moves, the first clamping structure 110 can be pushed to move along the same path. Referring to fig. 6, the unlocking mechanism 300 has an abutting end 310 that is in abutting engagement with the first clamping structure 110, the abutting end 310 is provided with a limiting portion 311, the limiting portion 311 is used for limiting engagement with a surface of the first clamping structure 110, which is away from the clamping portion 112, that is, the limiting portion 311 is clamped to a top surface of the first clamping structure 110, and it should be noted that, when the first clamping structure 110 is clamped to the second clamping structure 210, a surface of the first clamping structure 110, which is away from the second clamping structure 210, is the top surface of the first clamping structure 110. In the case that the pushing end 310 pushes against the first clamping structure 110, the limiting portion 311 is attached to the top surface of the first clamping structure 110. Because the first clamping structure 110 deforms when passing over the limiting member 130, the limiting portion 311 can stabilize the contact between the first clamping structure 110 and the pushing end 310. Specifically, when the first clamping structure 110 abuts against the limiting member 130 and the first clamping structure 110 deforms, the limiting portion 311 can limit the middle portion of the first clamping structure 110 to deform unnecessarily, so that the first clamping structure 110 can be smoothly switched to the second state under the action of the unlocking mechanism 300, and the unnecessary deformation includes the situation that the middle portion of the first clamping structure 110 is tilted upwards, so that the pushing end 310 cannot push the first clamping structure 110.

In other alternative embodiments, the sliding direction of the first clamping structure 110 is disposed intersecting the moving direction of the unlocking mechanism 300. In order to enable the unlocking mechanism 300 to push the first clamping structure 110 more conveniently, the end face of the pushing end 310 of the unlocking mechanism 300 is provided with a first guiding surface 312, the first guiding surface 312 is obliquely arranged, and the oblique direction is obliquely arranged along the moving direction of the first clamping structure 110 from the first state to the second state, and is from the first clamping structure 110 to the unlocking mechanism 300, as shown in fig. 10. In the process that the unlocking mechanism 300 pushes the first clamping structure 110 to slide, the first clamping structure 110 can slide along the first guiding surface 312, and the position of the first clamping structure 110 is lifted so that the first clamping structure 110 can slide smoothly along the sliding direction.

In some embodiments, the sliding direction of the first clamping structure 110 and the moving direction of the unlocking mechanism 300 are disposed perpendicular to each other, as shown in fig. 10. The first clamping structure 110 is directly lifted under the pushing of the unlocking mechanism 300, and is far away from the second clamping structure 210 in the lifting process. It should be noted that, in order to smoothly raise the first clamping structure 110, at least a portion of the pushing end 310 is located on a side of the first clamping structure 110 in the first state away from the limiting member 130, that is, a portion of the pushing end 310 is located below the first clamping structure 110 in the illustrated direction. In the case where the first clamping structure 110 and the second clamping structure 210 are in clamping engagement, a portion of the pushing end 310 needs to be inserted between the first clamping structure 110 and the mating connector 200. Along with the movement of the unlocking mechanism 300, the first guiding surface 312 can push the first clamping structure 110 to be lifted smoothly. In some alternative embodiments, to make the first clamping structure 110 smoothly switch from the first state to the second state, the height of the pushing end 310 is limited. Along the sliding direction of the first clamping structure 110, the sum of the height of the first clamping structure 110 and the height of the limiting member 130 is less than or equal to the height of the pushing end 310. In the process of lifting the first clamping structure 110 by the pushing end 310, the first clamping structure 110 can be smoothly lifted to the other side of the limiting member 130, and can be smoothly switched to the second state.

In addition, in some alternative embodiments, a side of the pushing end 310 near the first clamping structure 110 in the second state is provided with an avoidance gap 313, where the first clamping structure 110 may be clamped in the avoidance gap 313 when the first clamping structure 110 is in the second state, and the avoidance gap 313 may accommodate the first clamping structure 110 in the second state. In the process of pushing the first clamping structure 110 to lift by the pushing end 310, the resistance force applied to the unlocking mechanism 300 by the advancing movement of the unlocking mechanism 300 is larger, so that the external force applied to the unlocking mechanism 300 is larger, and in the process of separating the first clamping structure 110 from the first guiding surface 312 and clamping the avoidance notch 313, the resistance force applied to the advancing movement of the unlocking mechanism 300 is smaller, so that the external force applied to the unlocking mechanism 300 is smaller. When a user operates the unlocking mechanism 300, the user can obviously feel the change of the resistance born by the unlocking mechanism 300, and the operation hand feel can be changed, so that the user can conveniently judge whether the first clamping structure 110 is propped against in place. In addition, the avoidance notch 313 may limit the unlocking mechanism 300. After the avoidance notch 313 is in clamping fit with the first clamping structure 110, the unlocking mechanism 300 cannot move, so that an operator is further assisted in judging whether the first clamping structure 110 is propped in place.

In the process of switching the first clamping structure 110 from the first state to the second state, the surface of the limiting member 130, which is close to the first clamping structure 110 in the first state, is a second guiding surface 131, as shown in fig. 6 and 10, where the second guiding surface 131 has a guiding function, and the second guiding surface 131 is used for guiding the first clamping structure 110 to pass over the limiting member 130, and switch from the first state to the second state. Specifically, the second guiding surface 131 may have a slope structure or a smooth curved structure, so that the first clamping structure 110 passes over the limiting member 130.

The first clamping structure 110 needs to deform to pass through the limiting member 130, so as to complete the switching from the first state to the second state. The end portion of the first clamping structure 110, which is in sliding fit with the connector 100, is provided with a cavity 111, as shown in fig. 6 and 10, the structural strength of the first clamping structure 110 is changed by using the cavity 111, so that the structural strength of the end portion of the first clamping structure 110, which is in sliding fit with the connector 100, is reduced, the first clamping structure 110 is beneficial to being deformed under the condition that the first clamping structure 110 is pushed by the unlocking mechanism 300 and interacts with the limiting piece 130, and smoothly passes through the limiting piece 130, and the switching from the first state to the second state is completed. In some preferred embodiments, the cavity 111 is disposed at a portion of the first clamping structure 110 near the limiting member 130, so that the structural strength of a portion of the first clamping structure 110 contacting the limiting member 130 is reduced, which is more beneficial to deformation.

In some embodiments of the present application, the structure of the unlocking mechanism 300 may be as shown with reference to fig. 3. A sleeve 140 is provided on the connector 100, and the unlocking mechanism 300 is movably provided in the sleeve 140 so that the unlocking mechanism 300 can be moved in a preset direction. The sleeve 140 is used for limiting a moving path of the unlocking mechanism 300, so that the unlocking mechanism 300 can move in a preset direction to smoothly push against the first clamping structure 110. Illustratively, the sleeve 140 is positioned within the connector 100 as a channel structure disposed in the connector 100.

In some alternative embodiments, the first clamping structure 110 is clamped with the second clamping structure 210 due to the need. For example, the first clamping structure 110 has a protruding clamping portion 112, the second clamping structure 210 is a groove, and in the case that the clamping portion 112 is clamped in the groove, in order to make the clamping between them more stable, other portions of the first clamping structure 110 may be attached to the docking connector 200 as much as possible, so as to form a certain support for the first clamping structure 110, and the unlocking mechanism 300 has a certain wall thickness due to the need of setting the sleeve 140 to limit the movement direction, so that the unlocking mechanism 300 cannot be attached to the docking connector 200 for movement. Therefore, the abutting end of the unlocking mechanism 300 is bent towards the direction of the second clamping structure 210, so that the attaching area of the abutting end 310 and the first clamping structure 110 is as large as possible, and the abutting end 310 can be inserted under the first clamping structure 110.

In some embodiments of the present application, referring to fig. 3, the unlocking mechanism 300 includes a moving rod 330, the moving rod 330 is movably disposed in the sleeve 140, one end of the moving rod 330 is connected with a pressing portion 320, the other end of the moving rod 330 is an abutting end, a spring 340 is sleeved on the moving rod 330, and the spring 340 is also disposed in the sleeve 140. The unlocking mechanism 300 is made easier to operate by the pressing portion 320, and the pressing portion 320 is pressed to realize the movement of the unlocking mechanism 300. The spring 340 resets the unlocking mechanism 300. The connector 100 further includes a receiving groove 150 on a surface thereof, and the pressing portion 320 is disposed in the receiving groove 150 to increase a movement range of the pressing portion 320, that is, to increase a movement range of the unlocking mechanism 300. The moving direction of the moving rod 330 in the sleeve 140 may be a straight line direction or a curved line direction, which is not limited in this application.

Some embodiments of the present application further provide a connector 100 assembly, including the connector 100 provided in any embodiment, and a mating connector 200 located on a host, where the mating connector 200 is configured to be pluggable to the connector 100. The mating connector 200 includes a second clamping structure 210, and the second clamping structure 210 is configured to be in clamping engagement with the first clamping structure 110. Referring to fig. 12, a mating diagram of a mating connector 200 and a connector 100 according to one embodiment is shown. Referring to fig. 14, a mating diagram of a mating connector 200 and another embodiment of a connector 100 is provided.

In some alternative embodiments, the mating connector 200 is inserted into the outer sleeve 160 of the connector 100. For example, the first clamping structure 110 may be disposed at an end of the connecting body 170 or an inner wall of the outer sleeve 160, and the second clamping structure 210 is disposed at an end of the mating connector 200 or an outer peripheral wall thereof, so that the first clamping structure 110 and the second clamping structure 210 are in clamping fit.

In some alternative embodiments, the second clamping structure 210 is a clamping groove disposed on the surface of the mating connector 200, the surface of the mating connector 200 is further provided with a separation clamping groove 220 that is communicated with the second clamping structure 210, the separation clamping groove 220 is communicated with an end portion of the mating connector 200 for being mated with the connector 100, the second clamping structure 210 and the separation clamping groove 220 are arranged along the sliding direction of the first clamping structure 110, and the separation clamping groove 220 is distributed on one side of the second clamping structure 210 away from the unlocking mechanism 300.

In the process that the unlocking mechanism 300 pushes the first clamping structure 110 to be away from the second clamping structure 210, the first clamping structure 110 gradually slides out of the second clamping structure 210 and slides into the separating clamping groove 220, and as the separating clamping groove 220 penetrates through the end of the docking connector 200, when the connector 100 is separated from the docking connector 200, the first clamping structure 110 can smoothly slide out of the separating clamping groove 220 without damaging the docking connector 200. In some alternative embodiments, the sliding direction of the first clamping structure 110 is not perpendicular to the moving direction of the unlocking mechanism 300, and referring to fig. 13, the separating slot 220 and the first clamping structure 110 are arranged side by side, the first clamping structure 110 sliding out of the second clamping structure 210 slides into the separating slot 220, and the first clamping structure 110 is smoothly separated from the mating connector 200 by the separating slot 220.
