Description

Technical Field

[0001] The present invention relates to the technical field of endoscope camera systems, and in particular to a connecting device for endoscope camera systems. Background Art

[0002] The endoscopic camera system collects images from the surgical process and transmits them to the display for the doctor to make clinical judgments. The key to image transmission is to ensure reliable signal connection. Usually, the camera plug and host socket used for signal transmission are positioned by snaps or positioning columns. Limited by the level of technology, it is often impossible to determine whether the connector is inserted in place after assembly, which affects the reliable transmission of the signal, and the connector connection is prone to instability after frequent plugging and unplugging. While the camera system is lightweight in design, the large insertion and extraction force of the connector causes fatigue in the user's operation, and also causes excessive wear of the connector fixing structure, which affects the service life of the product. In addition, the wear of the shielding structure will cause the impedance of the camera system to increase, further affecting the anti-interference ability of the entire camera system. Summary of the invention

[0003] The technical problem to be solved by the present invention is: to provide a connecting device for an endoscopic camera system, which solves the problem that the connector used in the camera system cannot identify whether it is inserted in place by triggering a mechanical locking device and utilizing the friction self-locking principle. After identifying that it is inserted in place, the connecting device can be automatically locked, and the connector can be automatically unlocked when it is pulled out without an additional triggering device. Secondly, after the camera plug is unplugged, the mechanical locking device will automatically reset, and when it is inserted again, it can be smoothly inserted without overcoming the friction of other unnecessary parts, reducing operational fatigue; when it is pulled out, the friction movement stroke is reduced by reasonably setting the position of the card slot, reducing the wear of the connecting device, thereby increasing the service life. Thirdly, the two-way staggered arrangement of the shielding structure and the loop connection method at different angles improve the anti-interference ability of the camera system and reduce the failure risk of the unidirectional shielding structure.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] Furthermore, the shielding member is provided with spring sheets, the bending directions of the spring sheets are bidirectionally staggered, the spring sheets are arranged at different angles along the circumferential direction, the spring sheets are in elastic contact with the host housing and the camera plug, and the shielding member is fixed between the fixed seat assembly and the front guide seat.

[0007] Furthermore, the sliding mechanism moves through the first locking mechanism and the second locking mechanism and is fixedly connected to the rear fixing seat.

[0008] Furthermore, the limiting mechanism includes a limiting claw that is integrally processed with the first locking mechanism and the second locking mechanism, and the limiting claw abuts against the camera plug slot.

Through a mechanical locking mechanism and the principle of friction self-locking, the limiting mechanism will only execute an action when the trigger component recognizes that the camera plug is fully inserted into place, thereby avoiding the phenomenon of poor signal due to incomplete insertion, thereby interrupting the operation. When the camera plug is unplugged, it can be automatically unlocked without the need for other auxiliary mechanisms, reducing the complexity of the use process and operating fatigue. At the same time, the limiting mechanism will automatically reset after the camera plug is unplugged, and the next time the camera plug is inserted, it can be easily inserted without overcoming the friction of the limiting mechanism. In addition, the two-way staggered arrangement of the shielding plates and the loop connection method at different angles improve the anti-interference ability of the camera system and reduce the failure risk of the unidirectional shielding structure.

[0025] In order to keep the following description of the embodiments of the present invention clear and concise, the present invention omits detailed descriptions of some known functions and known components.

[0026] Please refer to the accompanying drawings, an embodiment of the present invention is:

[0027] A connection device for an endoscope camera system includes a host socket 1 and a camera plug 2 embedded in an image processing host. The host socket 1 includes an elastic locking component 11, a rear fixing seat 12, a second circuit board 13, a shielding member 14, and a front guide seat 15. The host socket 1 is arranged on a host housing 3, and a connector 16 connected to a conductive terminal 223 at a plug end is provided on the second circuit board 13.

[0028] The elastic locking assembly 11 includes a first elastic member 111, a second elastic member 112, a first locking mechanism 113, a second locking mechanism 114, a trigger member 115, a sliding mechanism 116, and a limiting mechanism 117. The elastic locking assembly 11 is fixedly connected to the rear fixed seat 12 through the sliding mechanism 116, and the limiting mechanism 117 is fixed to the first locking mechanism 113 and the second locking mechanism 114. The first locking mechanism 113 and the second locking mechanism 114 are respectively provided with a first slide rail 1131 and a second slide rail 1141, and the sliding mechanism 116 is provided with a slide groove 1161 corresponding to the position of the first slide rail 1131 and the second slide rail 1141. The first slide rail 1131 and the second slide rail 1141 are slidably connected in the slide groove 1161, and two fixing columns are fixedly connected to the sliding mechanism 116 for fixed connection with the rear fixed seat. The first locking mechanism 113 and the second locking mechanism 114 are respectively provided with long holes for positioning the fixing column. When the limiting mechanism 117 and the sliding mechanism 116 are slidably connected, the fixing column can slide freely forward and backward in the long holes.

[0029] A first positioning column 1132 and a second positioning column 1142 are respectively provided on the first locking mechanism 113 and the second locking mechanism 114 on a side facing away from the limiting mechanism 117, and the second elastic member 112 is connected to the first positioning column 1132 and the second positioning column 1142, wherein the first positioning column 1132 and the second positioning column 1142 are respectively provided on the first locking mechanism 113 and the second locking mechanism 114, so as to realize the linkage between the first locking mechanism 113 and the second locking mechanism 114, and the size of the plugging and unplugging force of the camera plug 2 can be adjusted by changing the elastic coefficient of the second elastic member 112.

[0030] The trigger member 115 is slidably connected to the sliding mechanism 116, and the first elastic member 111 is movably built into a side of the trigger member 115 close to the top surface. One end of the first elastic member 111 is higher than the top surface of the trigger member 115, and is used to provide movable displacement for the trigger member 115. The bottom surface of the trigger member 115 is placed toward the side of the camera plug 2.

[0031] The trigger member 115 has two side surfaces with a first end surface 1151 and a second end surface 1152 for abutting against the first locking mechanism 113 and the second locking mechanism 114 . When the camera plug 2 does not contact the trigger member 115 , the limiting mechanisms 117 at both ends are limited by the trigger member 115 .

[0032] The camera plug 2 includes a non-metallic shell 21 and a metal shell 22 . The metal shell 22 is provided with a card slot 222 , which is located at the front end of the metal shell 22 . A first circuit board 222 is provided inside the metal shell 22 , and a conductive terminal 223 is provided on the first circuit board 222 .

[0033] The shielding member 14 is provided with spring pieces 141, the bending direction of the spring pieces 141 is bidirectionally staggered, the spring pieces 141 are arranged at different angles along the circumferential direction, the spring pieces 141 are in elastic contact with the host housing 3 and the camera plug 2, and the shielding member 14 is fixed between the rear fixing seat 12 and the front guide seat 15. The bidirectional staggered arrangement of the shielding piece 14 and the loop connection at different angles improve the anti-interference ability of the camera system and reduce the failure risk of the unidirectional shielding structure.

[0034] The limiting column 1171 on the limiting mechanism 117 and the sleeve 1172 sleeved on the limiting column 1171 can also be limiting claws that are respectively integrally processed with the first locking mechanism 113 and the second locking mechanism 114. The limiting claw abuts against the slot 221, and the limiting claw is squeezed until the trigger member 115 is reset, and the first locking mechanism 113 and the second locking mechanism 114 are reset synchronously.

[0035] The limiting mechanism 117 includes a limiting column 1171 and a sleeve 1172 sleeved on the limiting column 1171 . The limiting column 1171 and the sleeve 1172 are clearance-matched to reduce the wear of the sleeve 1172 .

[0036] The material of the first elastic member 111 includes at least one of a spring, a rubber body, and an elastic plastic.

[0037] The working process of an embodiment of the present invention is as follows: the camera plug 2 is inserted, and before it contacts the trigger member 115, it does not need to overcome the friction force of the limiting mechanism 117. The camera plug 2 is corrected and guided by the front guide seat 15 when it does not contact the connector 16 provided on the second circuit board 13. When the camera plug 2 is not recognized as being inserted in place by the trigger member 115, the first locking mechanism 113 and the second locking mechanism 114 are always in contact with the first end face 1151 and the second end face 1152 of the trigger member 115, and the limiting mechanism 117 will not act.

[0038] When the camera plug 2 contacts the trigger member 115 and continues to be inserted, the first elastic member 111 is compressed and displaced until the trigger member 115 contacts the rear fixing seat 12 . At this time, the limiting mechanism 117 is displaced under the pulling force of the second elastic member 112 and is clamped in the card slot 221 .

[0039] When the camera plug 2 is unplugged, the limiting mechanism 117 is squeezed and displaced by the slot 221, and the trigger member 115 is reset under the action of the first elastic member 111, and the first locking mechanism 113 and the second locking mechanism 114 are respectively in contact with the first end face 1151 and the second end face 1152 of the trigger member 115 again.

[0040] The working principle is: when the camera plug 2 is not connected to the host socket 1, the trigger 115 is not triggered, and the limit mechanism 117 is limited at the maximum distance by the trigger 115. At this time, there is no need to overcome the friction of the limit mechanism 117 before the camera plug 2 contacts the trigger 115. After the trigger 115 is triggered, the camera plug 2 will not move when it is not fully inserted into place. The limit mechanism 117 will only act when the trigger 115 is compressed to contact the rear fixing seat 12. At this time, the limit mechanism 117 locks the camera plug 2. When the camera plug 2 is pulled out, the friction of the limit mechanism 117 needs to be overcome. After the limit mechanism 117 is squeezed out of the card slot 221, the trigger 115 resets and waits for the next insertion action of the camera plug 2. The next time the camera plug 2 is inserted, because the trigger 115 is in the reset state, it can be smoothly inserted without overcoming the friction of the limit mechanism 117.

[0041] The connection device for the endoscope camera system provided by the present invention can effectively solve the problem that the existing camera plug and host socket cannot recognize that the connection is in place, thereby improving the reliability of signal connection, the comfort of use, the product life and other issues.
