[0030] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] like Figures 1-6 As shown, a connector includes a socket assembly and a plug assembly that mates with the socket assembly. The socket assembly includes a socket body and an anti-disengagement structure disposed on the socket body. Specifically, the anti-disengagement structure can be an anti-disengagement step 15 or an anti-disengagement groove. The plug body includes a plug outer shell 1 and a plug inner shell 2 fixedly connected to the plug outer shell 1 and having an inner cavity that mates with the socket body. The side wall of the plug inner shell 2 has a through hole communicating with its inner cavity. A locking plate 3 that mates with the anti-disengagement step 15 or the anti-disengagement groove is slidably disposed in the through hole. The locking plate 3 has a central hole through which the socket body passes. A reset component is disposed between the locking plate 3 and the plug inner shell 2. In the initial state, the central hole on the locking plate 3 is eccentrically disposed with respect to the inner cavity of the plug inner shell 2. Preferably, the reset component is a spring 6. Of course, in addition to using a spring 6, elastic rubber, elastic silicone, gas springs, etc. can also be used.

[0032] It should be noted that, in this embodiment, an anti-disengagement step 15 is preferably provided on the socket body. When the plug assembly and the socket assembly are engaged, the locking plate 3 abuts against the anti-disengagement step 15, which is equivalent to forming a barbed structure to prevent the plug assembly and the socket assembly from separating.

[0033] To facilitate the mating of the plug assembly and the socket assembly, the central hole has a guide surface that facilitates the insertion of the socket body, or the central hole is tapered. When the socket body is inserted into the inner cavity of the plug inner shell 2, the socket body slides radially through the guide surface or the tapered central hole, causing the locking plate 3 to slide into place. After it is in position, under the action of the reset assembly, the locking plate 3 resets and cooperates with the anti-disengagement step 15 to achieve locking.

[0034] For ease of operation, a pressing member 5 is slidably provided on the plug housing 1, and a pressing part that cooperates with the pressing member 5 is provided on the locking plate 3. The reset component is provided between the pressing part and the plug inner housing 2. In addition, for ease of processing, the pressing part is formed by bending the locking plate 3 or by forming the two integrally.

[0035] Preferably, a limiting structure is further arranged between the plug inner housing 2 and the socket body, by which the PIN pin female head 14 can be completely aligned with the PIN pin male head 12 when the plug assembly and the socket assembly are matched, and no misoperation phenomenon exists. In the embodiment, the limiting structure comprises a foolproof protrusion fixedly arranged in the inner cavity of the plug inner housing 2, preferably a foolproof pin 11, and a foolproof groove 13 opened on the side wall of the socket body in the axial direction of the socket body and matched with the foolproof pin 11. Specifically, the foolproof groove 13 is preferably V-shaped. In addition to this, the limiting structure can also be a first limiting protrusion arranged in the inner cavity of the plug inner housing 2 and a second limiting protrusion arranged on the socket body, when the first limiting protrusion and the second limiting protrusion are in contact, the limiting function is realized, and the same can also achieve the purpose of foolproof.

[0036] The structure of the plug assembly is as follows: the first compression ring 9 is arranged between the plug outer housing 1 and the plug inner housing 2, the PIN pin male head 12 and the rubber ring 8 are fixedly arranged in the inner cavity of the plug inner housing 2, and the plug bottom cover 10 is fixedly arranged at the end of the plug inner housing 2.

[0037] Preferably, the end of the plug bottom cover 10 is embedded with a plurality of rubber pads 4 for anti-shaking which are symmetrically arranged with respect to the inner cavity of the plug inner housing 2. After the plug is inserted into the socket, the four anti-shaking rubber pads 4 provided on the plug bottom shell are compressed to generate a reaction force to push the plug to move upward (axially). At this time, the axial gap between the locking plate 3 and the socket anti-extraction step 15 is eliminated, and the plug and socket are balanced in axial and radial directions, and cannot be shaken.

[0038] The specific structure of the socket assembly is as follows: the socket body comprises a socket outer housing 7, a PIN pin female head 14 fixedly arranged on the socket outer housing 7 and matched with the PIN pin male head 12, a second compression ring 16 arranged between the PIN pin female head 14 and the socket outer housing 7, and a rubber pad sleeve 18 arranged between the socket outer housing 7 and an endoscope 17.

[0039] Principle and operation process: the middle of the locking plate 3 is provided with a tapered center hole, the small end diameter of the tapered hole is larger than the maximum outer diameter of the socket shell, in the initial state, the center hole of the locking plate 3 deviates from the center of the inner cavity of the plug assembly under the action of the spring force, that is, when the socket assembly is inserted into the plug assembly, a block is formed, and because the center hole is tapered, when the socket shell is pushed into the socket assembly, the maximum outer diameter of the socket shell interferes with one side of the tapered hole, after the plug is inserted into the socket assembly with force, the tapered hole edge on the plug locking plate 3 is in contact with the tapered skirt of the socket shell 7 under the action of the force, under the action of the force, the locking plate 3 is displaced and slides into the anti-disengagement step 15 of the socket to realize locking, on the contrary, when unlocking, the pressing piece 5 is pressed, the reset assembly is deformed, and the locking plate 3 is separated from the anti-disengagement structure under the action of the elastic force, so that the socket assembly can be smoothly pulled out of the plug assembly.

[0040] Therefore, in order to overcome the poor contact caused by the mechanical gap, the elastic interference fitting element is arranged in the axial and radial position of the connector to offset the mechanical gap, a circular groove is arranged in the inner cavity of the plug side, a rubber ring 8 is arranged in the groove and interferes with the socket to offset the radial gap, and the anti-shaking rubber pad 4 is arranged on the plug bottom cover 10 of the plug side to offset the axial gap between the plug assembly and the socket assembly, so that the plug is prevented from being loosened from the socket, the locking plate 3 is pushed into the anti-disengagement step 15 of the socket by the reset assembly, after the plug is inserted into the socket, the anti-shaking rubber pad 4 is compressed to generate a reaction force to push the plug upward, under the action of the reaction force of the anti-shaking rubber pad 4, the axial gap between the locking plate 3 and the anti-disengagement step 15 of the socket is offset, at this time, the plug and the socket are balanced in the axial and radial directions and cannot be shaken.

[0041] No figure is shown, in addition, the embodiment also provides a portable endoscope comprising the above connector 1.

[0042] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
