The present application is described below in conjunction with the accompanying drawings and with reference to specific embodiments:

In the related art, a self-destruction device is usually provided in the handle of the endoscope. After the endoscope is used once, the self-destruction device is automatically activated, causing the handle of the endoscope to lose part or all of its functions, thereby causing the endoscope to fail. Cannot be reused. However, how to determine that the endoscope has been used and enable the endoscope to self-destruct is a technical problem that those skilled in the art can solve.

Normally, as shown in FIGS. 1 and 2 , before the endoscope is used, the endoscope 20 needs to be plugged into the socket 11 on the image display 10 through the harness connector 21 to realize the connection between the endoscope 20 and the image display 10 . The signals between the image displays 10 are connected, and the image captured by the camera module at the far end of the insertion section of the endoscope 10 is transmitted to the image display through the wiring harness connector 21 for real-time display. Furthermore, the wire harness connector 21 of the endoscope is unplugged from the socket of the image display only when the endoscope is used.

It can be seen from this that when the wire harness connector 21 of the endoscope 20 is separated from the socket 11, it means that the endoscope has been used. Based on this point, the present application provides a wire harness connector 21, which is connected to the wire harness 23. It can then be used as a plug of the endoscope 20 and be connected to the socket 11 of the image display 10 during use. After the wire harness connector 21 is pulled out of the socket 11, at least part of the signal transmission lines inside the wire harness connector 21 will be broken, making the endoscope to which the wire harness connector 21 belongs unable to be used again, thus achieving the purpose of making the endoscope unable to be reused.

As shown in FIGS. 2 to 11 , the structure of the wire harness connector 21 includes a connector body 100 , a sliding member 200 , a first elastic member 300 and a second elastic member 400 .

As shown in Figure 3, the connector body 100 is the installation basis of the wire harness connector 21. A plurality of terminals 110 are provided on the connector body 100. The length direction of the terminals 110 is arranged along the axial direction of the connector body 100, and both ends of the terminals 110 are respectively protruding. to the outside of both axial ends of the connector body 100, so that the two ends of the terminal 110 form a mating end 111 and a connecting end 112 respectively. Among them, the docking end 111 is used to insert into the socket hole in the socket 11 of the image display 10 , and the connecting end 112 is used to connect the wires in the wiring harness 23 on the endoscope handle 22 to realize the connection between the image display 10 and the endoscope 20 There is electrical conduction between them, thereby transmitting the electrical signals and/or optical signals required for the use of the endoscope.

As shown in FIGS. 4 to 6 , a first slide groove 120 and a first slot 130 are provided on the side wall of the joint body 100 . The first slide groove 120 is provided along the axial direction of the joint body 100 so that the first slide groove 120 is disposed on the side wall of the joint body 100 . The two ends of the groove 120 in the length direction are respectively facing the direction of the butt end 111 and the direction of the connecting end 112 . The end of the connector body 100 where the butt end 111 is located is the distal end of the connector body 100, and the end of the connector body 100 where the connecting end 112 is located is the active proximal end of the connector. In the various embodiments of this application, the "proximal end" and "distal end" refer to the far and near position of the endoscope and its accessories relative to the user in the use environment, where the end closer to the user It is designated as the "near end", and the end farther away from the user is designated as the "far end". The first slot 130 is disposed radially along the connector body 100 . The first slot 130 can be disposed inside the first slide groove 120 or outside the first slide groove 120 . As shown in Figure 5, the connector body 100 is also provided with a connecting channel 140. One end of the connecting channel 140 is connected to the first chute 120, and the other end of the connecting channel 140 penetrates to the proximal end of the connector body 100. The connecting channel 140 It can be either a slot channel or a hole channel.

At least a part of the sliding member 200 is located in the first sliding groove 120 , so that the sliding member 200 can slide in the first sliding groove 120 along the length direction of the first sliding groove 120 without being subjected to other resistance. The sliding member 200 has a connecting portion 210. The connecting portion 210 of the sliding member 200 can be fixedly connected to the wire 24 or the connecting end 112 of the terminal 110 through the connecting channel 140, so that the sliding member 200 slides along the first slide groove 120 toward the connector. When the main body 100 slides in the distal direction, the connected wire 24 or terminal 110 can be pulled. The wires 24 here refer to the wires in the wiring harness 23 . Normally, the wire 24 and the terminal 110 are connected by soldering. When the slider 200 connects the wire 24, the slider 200 pulls the wire 24 into the connection channel, causing the welding point between the wire 24 and the terminal 110 to fall off. , causing the terminal 110 to be disconnected from the wire. Of course, if other connection methods are used between the terminal 110 and the conductor 24, when the sliding member 200 provides sufficient pulling force for the conductor 24, pulling the conductor 24 can still disconnect the conductor 24 from the connecting end 112 of the terminal 110. . When the sliding member 200 connects the terminal 110, the sliding member 200 pulls the terminal 110 in the direction of the connecting channel 140 and bends the connecting end 112 of the terminal 110, so that the connecting end 112 of the terminal 110 itself breaks, thereby causing the terminal 110 to break. Disconnect from wire 24.

In addition, it should be noted that the connecting part 210 may be a component integrally formed with the slider 200 , or may be a component formed after being fixedly connected to the slider 200 . The connecting part 210 may be a rigid component, for example, the connecting part 210 Integrated with the sliding part 200 or fixedly connected by bonding, snapping, etc., the connecting part 210 may also be a flexible part, for example, the connecting part 210 may be a rope. When the sliding member 200 is connected to the wire 24, depending on the length of the connecting portion 210, the body portion of the wire 24 can be inserted into the connecting channel 140 and fixedly connected to the connecting portion 210 of the sliding member 200, or the sliding member can be connected to the connecting portion 210 of the sliding member 200. The connecting portion 210 of 200 penetrates into the connecting channel 140 and is fixedly connected to the wire 24 . The fixed connection methods of the wires 24 here include but are not limited to knotting, perforation, bonding, etc. When the sliding member 200 is connected to the terminal 110, the connecting portion 210 of the sliding member 200 can be fixedly connected to the connecting end 112 of the terminal 110 after passing through the connecting channel. The fixed connection method for the terminal 110 here includes but is not limited to bonding, snapping, bolting, etc. In order to make the connecting end 112 of the terminal 110 easier to break under the pull of the slider 200, the structure of the connecting end 112 can be configured to make it easier to break. For example, the connecting end 112 is made of pins with smaller diameters. The connecting end 112 is provided with cuts, holes, etc. that facilitate fracture; the material of the terminal 110 can also be configured to make it easier to fracture, such as using a material that is more prone to ductile fracture or brittle fracture. In this regard, this embodiment does not limit the specific structure or material of the connecting end 112 .

The first elastic member 300 is a component capable of elastic deformation, and may be a sheet-shaped elastic piece or a spiral spring. The first elastic member 300 has a fixed end and an elastic end. The fixed end of the first elastic member 300 is disposed on the sliding member 200 and is connected to the sliding member 200. The fixed end may be detachable through bolts, buckles, etc. The connection can also be connected through one-piece molding. The elastic end of the first elastic member 300 can elastically deform relative to the fixed end when subjected to external force, and the directions of elastic deformation of the first elastic member 300 include at least two opposite directions: close to the joint body 100 and away from the joint body 100 . direction, that is, the first elastic member 300 has one side facing toward the joint body 100 and another side facing away from the joint body 100 . The elastic end of the first elastic member 300 is provided with an outwardly protruding first insertion portion 320 and abutment portion 310 . The contact portion 310 and the first plug-in portion 320 are both located on a side of the first elastic member 300 facing the connector body 100 . When the first elastic member 300 is in a natural state without being affected by external force, the first plug-in part 320 is plugged into the first slot 130 so that the first plug-in part 320 blocks and restricts the sliding part 200 . The sliding member 200 slides, so that when the wire harness connector 21 is not connected to the socket of the image display, the sliding member 200 causes the terminal 110 to disconnect from the wire. When the first plug-in part 320 is plugged into the first slot 130 , the contact part 310 and the connector body 100 are relatively fixed. The contact portion 310 is configured to move in the radial direction away from the connector body 100 after the contact portion 310 contacts the socket. Specifically, when the wire harness connector 21 is plugged into the socket, the contact portion 310 can contact the socket. , and is subject to the contact force of the socket against the contact portion 310 , at least a part of the contact force is parallel to the radial direction of the connector body 100 and extends away from the connector body 100 . Therefore, the socket has an extrusion force on the contact portion 310 to move the contact portion 310 away from the connector body 100 , thereby causing the elastic member of the first elastic member 300 to elastically deform and bend to the other side, driving the first plug-in portion. 320 leaves the first slot 130, and the first plug-in part 320 releases the fixation of the first elastic member 300.

The second elastic member 400 is disposed in the first slide groove 120. One end of the second elastic member 400 is connected to the joint body 100, and the other end is connected to the sliding member 200. The second elastic member 400 is configured to provide a pushing force to the sliding member 200 away from the proximal end of the joint body 100 . When the first insertion part is inserted into the first slot 130 , the second elastic member 400 is in an elastic deformation state, and the second elastic member 400 has a pushing force on the sliding member 200 . After the first insertion part leaves the first slot 130, the pushing force of the second elastic member 400 on the sliding member 200 can push the sliding member 200 to move in the direction away from the connection channel in the first slide groove 120, that is, the sliding member 200 moves away from the connection channel. The direction of the connection end 112 of the terminal 110 moves. The second elastic member 400 may be a sheet-shaped elastic piece or a spiral spring.

Through the above-mentioned wire harness connector 21 having the connector body 100, the sliding member 200, the first elastic member 300 and the second elastic member 400, as shown in the above-mentioned Figures 1-7 and Figures 8 and 9, the wire harness connector 21 and the corresponding During the socket docking process, the socket body 12 and the connector body 100 on the socket are close to each other, and the butt ends 111 of the terminals 110 on the connector body 100 can be inserted into the wire harness connectors in the socket corresponding to the corresponding terminals 110 along the insertion direction. 21 Electrical connection to socket. Moreover, during this process, the socket body 12 will contact the contact portion 310 on the first elastic member 300, and push the contact portion 310 outward to cause the first elastic member 300 to elastically deform, and the first elastic member 300 will elastically deform. During the elastic deformation of the component 300, the first plug-in part 320 can be separated from the first slot 130. After the terminals 110 on the connector body 100 and the insertion holes on the socket body 12 are inserted into place, the contact portion 310 and the socket body 12 are kept relatively fixed by friction. The friction force is greater than the sliding force of the second elastic member 400 . Piece 200 thrust. After the endoscope is used, it is necessary to separate the wire harness connector 21 from the socket. During this process, the socket body 12 moves in the reverse direction. At the same time, the first elastic member 300 and the sliding member 200 are pushed by the second elastic member 400. Move downward toward the distal direction of the connector body 100 so that the sliding member 200 and the first elastic member 300 can follow the movement of the socket body 12. Then, after the wire harness connector 21 is completely separated from the socket, the sliding distance of the sliding member 200 can be enough to remove the wire 24. Pull to separate from the connecting end 112 or break the connecting end 112 so that the terminal 110 cannot be conducted. Furthermore, even if the wire harness connector 21 is reconnected to the socket, the terminal 110 cannot be connected, which may cause signal transmission problems between the wire harness connector 21 and the image display 10 , making the endoscope unable to be reused.

It should be noted that while the sliding member 200 is sliding in the first chute 120 , the first chute 120 can restrict the sliding member 200 from moving in a direction away from the joint body 100 , that is, the first chute 120 has a direct impact on the sliding member 200 . The first elastic member 300 prevents the sliding member 200 from being separated from the first slide groove 120 in this direction when receiving the contact force of the socket body 12 .

Further, in this embodiment, the sliding member 200 is annular with a through hole in the middle. The first slide groove 120 is an annular groove opened in the circumferential direction of the joint body 100. The sliding member 200 is sleeved in the annular groove to realize sliding. The connection between the member 200 and the first slide groove 120 enables the joint body to have a radial limiting function for the annular member. On the other hand, the annular structure of the slider 200 and the end of the slider 200 can also guide the socket body 12, so that the docking position of the socket body 12 and the connector body 100 is more accurate, and the terminal 110 can be inserted more accurately. into socket 11.

It should be noted that setting the circumferential side wall of the joint body 100 into a cylindrical shape is also equivalent to opening an annular groove on the side wall of the joint body 100 . When the first chute 120 is an annular groove, the second elastic member 400 is preferably a spring, so that the elastic force generated by the second elastic member 400 can act more uniformly on the annular groove by sleeved on the joint body 100 . on the sliding piece 200.

Of course, in some optional ways, if the first chute 120 is a strip groove, the first chute 120 can be configured as a dovetail groove or a T-shaped groove or other structure capable of radial limiting, and the sliding member 200 is configured as a dovetail body adapted to the dovetail groove or the first sliding member 200 is configured as a T-shaped body adapted to the T-shaped groove, so that the sliding member 200 does not move along the joint body 100 in the first slide groove 120 Radial movement.

Furthermore, an annular boss is provided at the proximal end of the connector body 100 , and one end of the spring used in the second elastic member 400 can abut against the boss to realize the connection between the second elastic member 400 and the connector body 100 . When the second elastic member 400 adopts a spring, the connecting channel is a groove, one end of the connecting channel is disposed at the bottom of the first slide groove 120 , and the other end of the connecting channel penetrates to the proximal end of the connector body 100 . This arrangement allows the connection channel to be located inside the spring, and when the sliding member 200 is connected to the wire through the connection channel, the interference of the spring on the wire can be reduced.

In this embodiment, a relief groove 220 is provided on the side wall of the sliding member 200. The relief groove 220 penetrates the side wall of the sliding member 200. The relief groove 220 is a non-linear groove, and the beginning and end of the relief groove 220 are not connected. Therefore, the first elastic member 300 is defined in the area enclosed by the relief groove 220 . With this arrangement, the sliding member 200 and the first elastic member 300 can be integrally formed, making processing easier. At the same time, the first elastic member 300 is a sheet-shaped elastic piece, and it is easier to provide the contact portion 310 and the first plug-in portion 320 on the elastic piece. Of course, in some optional implementations, the first elastic member 300 may also use other elastic structural members such as springs, and other elastic structural members may be disposed at the end of the sliding member 200 .

Optionally, in this embodiment, the relief groove 220 is U-shaped, the first elastic member 300 is elongated, and the length direction of the first elastic member 300 is parallel to the length direction of the sliding member 200 . The elongated first elastic member 300 may have a larger elastic deformation amount and be more prone to deformation. Of course, in some optional implementations, the first elastic member 300 may be in a triangular, arc-shaped or other structural form.

The first slot 130 is a strip slot, the length direction of the first slot 130 is parallel to the sliding direction of the sliding member 200 in the first chute 120 , and the length of the first slot 130 is shorter than the connector body 100 axial length. With this arrangement, when the wire harness connector 21 is produced and assembled, the first plug-in part 320 can be more easily plugged into the first slot 130 .

Further, one end of the first chute 120 penetrates the distal end of the connector body, the distal end of the sliding member 200 is located outside the connector body 100, and the diameter of the through hole at the distal end of the sliding member 200 is adapted to the socket body 12. The first The elastic member 300 is spaced apart from the distal end of the sliding member 200 . With this arrangement, the distal end of the sliding member 200 can contact the socket body 12 before the abutment portion 310 , so that the distal end of the sliding member 200 can limit and guide the socket body 12 , thereby allowing the socket body to be inserted. The direction will not shift, and the socket body can maintain consistency with the action position of the contact portion 310 .

Furthermore, the distal end of the sliding member 200 is provided with a flare 150. The surface of the flare 150 is not parallel to the radial direction of the slide 200. The flare 150 can further guide the socket body, thereby making it easier for the socket body to enter. in the via hole formed by the sliding member 200 .

In addition, the length of the butt end 111 of the terminal 110 protruding from the connector body 100 is greater than the distance between the distal end of the slider 200 and the distal end of the connector body 100, so that when the wire harness connector is butt with the socket, the butt end 111 is first inserted into the jack of the socket. , so that the socket body enters the through hole of the sliding member 200 under the pre-guided action of the docking end 111 and the jack hole. Of course, if there are other pre-guided structures between the socket body and the sliding member, the length of the docking end 111 protruding from the connector body 100 can also be set to be smaller than the distance between the distal end of the sliding member 200 and the distal end of the connector body 100 .

As shown in the above-mentioned Figures 1-9 and Figures 10 to 11, the wire harness connector 21 provided in this embodiment also includes a shell 500. The shell 500 is cylindrical. The shell 500 covers the connector body 100 and the sliding member 200, and The shell 500 is fixed on the joint body 100, and the fixing method includes but is not limited to bolt fixing and clamping fixation. The sliding member 200 can slide relative to the housing 500 in the first slide groove 120 . The housing 500 can protect the sliding member 200 so that the sliding member 200 will not come into direct contact with other items before the wire harness connector 21 is used, thereby preventing the first plug portion 320 from being separated from the first slot 130. When the wire harness connector 21 is docked with the socket, the socket body 12 on the socket can contact the sliding member 200 after being inserted into the housing 500 , thereby avoiding accidental damage to the wire harness connector 21 . At the same time, the housing 500 can also protect the butt end 111 of the terminal 110 to prevent the butt end 111 from bending or breaking. The shell 500 can play a role in pre-guiding the socket body.

Further, a second slot 510 is provided on the shell 500, and the second slot 510 and the second slot 510 are respectively located on both sides of the first elastic member 300 in the elastic direction. The notches of the two slots 510 both face the first elastic member 300 . The first elastic member 300 is provided with a second plug-in part 330 that protrudes outward. The second plug-in part 330 faces the second slot 510 and is plugged into the second slot 510 at the first plug-in part 320 . When inside, the second plug portion 330 is located outside the second slot 510 . When the first elastic member 300 is abutted by the socket body 12 , the first elastic member 300 elastically deforms toward the upper direction of the housing 500 , causing the first plug portion 320 to separate from the first slot 130 , and simultaneously causing the second The plug portion 330 is inserted into the second slot 510 . After the second plug portion 330 is inserted into the second slot 510, the sliding member 200 and the housing can be relatively fixed. Since the housing and the connector body 100 are relatively fixed, the sliding member 200 can still remain between the connector body 100 and the connector body 100. are relatively fixed. This arrangement can prevent the sliding member 200 from moving under the thrust of the second elastic member 400 due to insufficient friction between the sliding member 200 and the socket body 12 after the first plug-in portion 320 is separated from the first slot 130. As a result, the terminal 110 and the conductor 24 are disconnected in advance.

Preferably, in this embodiment, along the radial direction of the connector body 100, the depth at which the first plug-in part 320 is inserted into the first slot 130 is less than the distance between the second plug-in part 330 and the second slot 510, so that The configuration can ensure that after the first plug-in part 320 is separated from the first slot 130, the second plug-in part 330 must be inserted into the second slot 510.

Further, in this embodiment, when the first plug-in part 320 is plugged into the first slot 130, along the axial direction of the connector body 100, the distal end of the second plug-in part 330 is in contact with the second slot 130. There is a gap between the distal ends of 510. Such an arrangement can enable the second plug-in part 330 to be moved away from the proximal end of the connector body 100 under the thrust of the second elastic member 400 when the second plug-in part 330 is plugged into the second slot 510 . until the distal end of the second plug-in part 330 contacts the distal end of the second slot 510. At this time, the first plug-in part 320 is misaligned with the first slot 130, so that the first plug-in part 320 is dislocated. 320 cannot go back to the first slot 130.
