Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and in particular to a camera connector. Background Art

[0002] A connector is a device used to connect two active devices, which can transmit current or signals. Its function is to establish an electrical connection between different electronic devices, components or systems so that they can work together. Connectors usually include contacts, insulators, shells and accessories. The contacts are the core parts of the connector to complete the electrical connection function. They are usually composed of positive contacts and negative contacts. The positive contacts are generally pins, and the negative contacts are generally jacks. The conduction of current or signals is achieved through the close fit between them; the insulator mainly plays an insulating role to prevent short circuits between adjacent contacts; the shell is the outer protective layer of the connector, which can provide mechanical protection to prevent the connector from being physically damaged, and can also play an electromagnetic shielding role to reduce the impact of external electromagnetic interference on internal signal transmission; accessories include various auxiliary components, such as locking devices, sealing devices, etc. The locking device can ensure that the connector will not loosen easily after connection, and the sealing device is used in some special environments (such as environments with waterproof and dustproof requirements) to prevent foreign substances from entering the connector and affecting its performance. In the related art, a dust cap is usually provided on the socket to prevent dust from entering the socket. The dust cap includes a split dust cap and an integrated dust cap. The split dust cap is easy to be lost when the socket is unplugged, and the integrated dust cap usually falls beside the plug and the socket when the plug is inserted into the socket. After long-term use, the dust cap itself is easily attached with dust, resulting in reduced dust prevention effect.

[0003] The Chinese patent application with application publication number CN115911974A discloses an anti-loosening and waterproof electrical connector with a secondary locking structure, which includes a socket, a plug, and a tail accessory. The front end of the plug is locked with the socket through a bayonet connection, and the end of the plug is fixedly connected with the tail accessory. The plug includes a plug housing, and an anti-loosening arc swivel and an anti-loosening step are provided on the outer wall of the plug housing. A connecting nut assembly is provided on the outer sleeve of the front end of the plug housing, and the connecting nut assembly includes a connecting nut, and an anti-loosening slider structure that matches the anti-loosening arc swivel and the anti-loosening step is processed on the inner wall of the rear end of the connecting nut, and an arc swivel groove that matches the socket is processed on the inner wall of the front end of the connecting nut. The connecting nut, the anti-loosening slider structure, the anti-loosening arc swivel, and the anti-loosening step cooperate to form a secondary locking and anti-loosening structure.

[0004] The above patent application adopts a bayonet method to connect the plug and the socket. On the one hand, by designing a connecting nut on the plug housing, adding anti-loosening mechanisms, anti-loosening arc rotation, waterproof sealing grooves and other structures, the product can achieve quick connection, secondary anti-loosening and waterproof functions. In addition, by designing the tail accessories with threaded anti-loosening holes, O-ring grooves, gaskets, and rubber ring structures, it is easy to prevent the tail accessories from loosening, seal and fix the wires during use.

[0005] However, the waterproof and dustproof performance of the above patent application is insufficient when the connector is in the unconnected state. When the connector is in the unconnected state, dust and water easily enter the socket, resulting in poor contact between the plug and the socket when connected. Therefore, it is necessary to provide a connector that can prevent dust and water from entering the socket in both the connected and unconnected states. Summary of the invention

[0006] The present invention provides a camera connector, aiming to solve the problem in the related art that dust and water are easily intruded into a socket in an unconnected state.

[0007] The camera connector of the present invention comprises: a plug, a socket and a sealing assembly;

[0008] The plug comprises a plug housing and a plug pin, wherein the plug pin is arranged in the plug housing;

[0009] The socket comprises a socket shell and a socket contact, the socket has a matching hole for the plug shell to be plugged into, and the socket contact is arranged in the matching hole;

[0010] The sealing assembly includes a plurality of flexible blades, each of which is arranged at the opening of the mating hole, and is continuously distributed along the circumference of the mating hole. The flexible blades are spliced ​​together to seal the mating hole. When the plug is plugged into the socket, each flexible blade can be folded inwardly under the top pressure of the plug shell and is located between the plug shell and the inner wall of the mating hole, and the two sides of the flexible blades are tightly fitted with the plug shell and the hole wall of the mating hole respectively.

[0011] The beneficial effect is that when the plug is not connected to the socket, the multiple flexible blades fit together to form a circular structure, and the two adjacent flexible blades fit closely together, so that the circular structure formed by the multiple flexible blades can close the matching hole, preventing dust, water and other impurities from entering the matching hole. When the plug is connected to the socket, the plug shell can push the flexible blades to flip inward when it extends into the matching hole, so that the flexible blades are sandwiched between the plug shell and the socket shell, and the flexible blades can fill the gap between the plug shell and the matching hole, preventing dust, water and other impurities from entering the matching hole through the gap between the plug shell and the matching hole, resulting in poor contact between the plug and the socket. The camera connector of the present invention can prevent dust and water from entering the socket in both the connected state and the non-connected state, thereby preventing the plug and the socket from having poor contact when connected.

[0012] Preferably, the plug shell is a circular tubular structure, the matching hole is a circular hole, the flexible blades are a fan-shaped structure, the arcuate edges of each flexible blade are fixed at the opening of the matching hole, and the flexible blades are spliced ​​together to form a circular dustproof pad.

[0013] Preferably, the outer wall of the plug shell is provided with sliding grooves evenly spaced along the circumferential direction, the number of the sliding grooves is the same as the number of flexible blades, each sliding groove is provided with a limit block, and an elastic sealing gasket is fixed on the outer end face of each limit block, the shape of the sealing gasket is adapted to the shape of the gap between two adjacent flexible blades folded inwardly, and an adjusting mechanism that can drive each limit block to extend outward or retract into the sliding groove is also provided in the plug shell, when the plug shell is plugged into the mating hole, the limit block extends outward to press the sealing gasket against the hole wall of the mating hole, and the sealing gasket is stuck between the two adjacent flexible blades.

[0014] The effect is that after the socket shell is inserted into the matching hole, the limit block extends out of the plug shell and is stuck between the two flexible blades. The limit block is respectively stopped by the two flexible blades, thereby limiting the rotation of the plug shell relative to the socket shell, and preventing the plug shell from being pulled out of the matching hole, achieving the clamping connection between the plug shell and the socket shell, and preventing the plug from being disconnected from the socket. At the same time, the sealing gasket can be assembled with the flexible blades to form an annular sealing ring, further preventing impurities from entering the matching hole.

[0015] Preferably, the limit block is a triangular structure, each of the limit blocks can be stuck between two adjacent flexible blades, and the two side walls of the limit block can fit with the two flexible blades respectively.

[0016] The effect is that the limit block is set to a triangular structure, so that the limit block is adapted to the shape of the gap between two adjacent blades, preventing a gap from being generated between the limit block and the flexible blades, and the socket shell can rock relative to the plug shell, thereby preventing poor contact due to rocking when the plug and the socket are connected.

[0017] Preferably, the adjusting mechanism comprises a rotating shaft, a push rod, a rotating ring and a connecting rod, the rotating shaft and the rotating ring are coaxially arranged, the rotating shaft is fixedly connected to the inner wall of the rotating ring through the connecting rod, the number of the push rods is the same as the number of the limit blocks, the push rods are evenly spaced and fixed on the rotating shaft along the circumference of the rotating shaft, and the push rods are perpendicular to the rotating shaft; the bottom wall of each slide groove of the plug shell is also provided with an avoidance hole connecting the slide groove and the internal space of the plug shell, and the outer circumferential surface of the plug shell near the rear end is also provided with a mounting hole, the rotating shaft and each push rod are rotatably inserted in the plug shell, the rotating shaft and the plug shell are coaxially arranged, the push rods are respectively located in each avoidance hole, and the push rods respectively correspond to each limit block one by one, the rotating ring is rotatably mounted on the plug shell, and the connecting rod is located in the mounting hole; when the rotating ring rotates, it can drive the connecting rod and the push rod to rotate synchronously, and when the rotating shaft rotates clockwise, the push rod can gradually approach the limit block and stop with the inner end of the limit block, and can push the limit block out of the slide groove.

[0018] The effect is that the rotating shaft is driven to rotate by the adjusting mechanism, and when the rotating shaft rotates clockwise, the push rod gradually approaches the limit block until it stops with the limit block. At this time, the rotating shaft continues to rotate clockwise so that the push rod pushes the limit block to overcome the pulling force of the first elastic member and extend out of the plug shell and fit between the two flexible blades. When the rotating shaft rotates counterclockwise, the push rod gradually moves away from the limit block, and the limit block is retracted into the plug shell under the pulling force of the first elastic member. When the plug shell is extended into the matching hole, the limit block is controlled by the adjusting mechanism to be retracted into the plug shell to prevent the limit block from stopping with the socket shell, causing the limit block to hinder the plug shell from extending into the matching hole. When the plug shell is completely extended into the matching hole, the adjusting mechanism controls the limit block to extend out of the plug shell, and the limit block is engaged with the flexible blades to fix the plug shell. When the connection needs to be disconnected, the adjusting mechanism controls the limit block to be retracted into the socket shell, and the limit block is disengaged from the flexible blades, thereby releasing the limit on the plug shell and facilitating the plug shell to be pulled out of the matching hole.

[0019] Preferably, a first elastic member is also provided in the slide groove, one end of the first elastic member is fixedly connected to the inner end surface of the limit block, and the other end of the first elastic member is fixedly connected to the bottom wall of the slide groove, and when the first elastic member is in a normal state, the limit block is located in the slide groove.

[0020] The effect is that when the limit block is located in the slide groove, the first elastic member is in a natural state. When the first elastic member extends out of the slide groove, the first elastic member is stretched. When the connection between the plug and the socket needs to be disconnected, the adjusting mechanism is rotated to make the push rod disengage from the limit block. The limit block can be retracted into the slide groove and reset under the pulling force of the first elastic member.

[0021] Preferably, it also includes a limit assembly, which includes a limit rod, a second elastic member and a limit groove provided on the inner end face of the limit block, the outer end of the push rod is a hollow structure, the limit rod is slidably installed in the hollow structure of the push rod, the limit rod can move along the radial direction of the rotating shaft and extend the push rod, the limit rod is elastically connected to the push rod through the second elastic member, the limit groove is an arc-shaped groove, the outer end of the limit rod is an arc-shaped structure adapted to the arc-shaped groove, and the second elastic member is in a compressed state when the limit rod is located in the hollow structure of the push rod; when the rotating ring drives the push rod to rotate so that the push rod is perpendicular to the inner end face of the limit block, the limit rod can extend outward from the push rod under the elastic force of the second elastic member and extend into the limit groove.

[0022] The effect is that the second elastic member is always in a compressed state. When the push rod is perpendicular to the inner end surface of the limit block, the limit groove is aligned with the limit rod. The limit rod extends into the limit groove under the elastic force of the second elastic member, thereby achieving a clamping connection between the push rod and the limit block, preventing the plug and the socket from being disconnected during the connection process. When the plug housing is pulled out, it is only necessary to rotate the rotating ring with a little force, and the rotating shaft drives the push plate to rotate. During the rotation of the push plate, the limit rod is squeezed out of the limit groove. At this time, the second elastic member is compressed, and the limit rod is re-entered into the push rod.

[0023] Preferably, the plug shell includes a coaxially arranged large diameter section and a small diameter section, the outer diameter of the large diameter section is larger than the outer diameter of the small diameter section, the small diameter section is fixedly arranged at the front end of the large diameter section, the outer diameter of the small diameter section is smaller than the aperture of the matching hole, and the small diameter section is used to be inserted into the matching hole; a positioning mechanism is also provided on the plug shell and the socket shell, the positioning mechanism includes a positioning protrusion and a positioning groove, the positioning protrusion is arranged on the front end surface of the large diameter section, and the positioning groove is arranged on the rear end surface of the socket shell, the positioning protrusion can be extended into the positioning groove one by one, and when the positioning protrusions are extended into the positioning groove one by one, the limit block extends outward to press the sealing gasket against the hole wall of the matching hole, and the sealing gasket is just stuck between two adjacent flexible blades.

[0024] The effect is that when the small diameter section is completely inserted into the matching hole, the large diameter section stops against the socket shell. At this time, the positioning protrusion can be extended into the positioning groove by rotation. When the positioning protrusion extends into the positioning groove, the limit block extends outward to press the sealing gasket against the hole wall of the matching hole. The sealing gasket is just stuck between the two adjacent flexible blades, which facilitates the positioning of the limit block during the connection process.

[0025] Preferably, a filling pad is further provided on the side wall of the limit block, and a filling pad is further provided on the side wall of the limit block. The filling pad has good deformation ability and is used to prevent a gap from being generated between the limit block and the flexible blade.

[0026] The effect is that when the limit block extends out of the plug shell and fits with the two flexible blades on both sides thereof, the filling pad is located between the limit block and the corresponding flexible blades, further preventing a gap from being generated between the limit block and the flexible blades, causing the limit block to move relative to the flexible blades, the plug shell to shake relative to the socket shell, and the plug and the socket to shake and cause poor contact.

[0027] Preferably, an insulating layer is provided on the outer circumference of the plug housing and the socket housing.

[0028] The effect is that the insulating layer acts as a physical barrier to protect the plug shell and the socket shell, and produces a buffering effect when the plug shell and the socket shell are impacted by external force, thereby preventing the plug shell and the socket shell from being damaged due to external force impact. At the same time, the insulating layer can isolate the plug shell and the socket shell from the outside world, thereby preventing the plug shell and the socket shell from being electrically connected to the outside world and causing a short circuit.

[0029] By adopting the above technical solution, the beneficial effects of the present invention are:

[0030] When the plug is not connected to the socket, the multiple flexible blades fit together to form a circular structure, and two adjacent flexible blades fit closely together, so that the circular structure formed by the multiple flexible blades can close the matching hole and prevent dust, water and other impurities from entering the matching hole. When the plug is connected to the socket, the plug shell can push the flexible blades to flip inward when it extends into the matching hole, so that the flexible blades are sandwiched between the plug shell and the socket shell, and the flexible blades can fill the gap between the plug shell and the matching hole, preventing dust, water and other impurities from entering the matching hole through the gap between the plug shell and the matching hole, resulting in poor contact between the plug and the socket. The camera connector of the present invention can prevent dust and water from entering the socket in both the connected state and the non-connected state, thereby preventing the plug and the socket from having poor contact when connected.

DETAILED DESCRIPTION

[0043] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0044] The camera connector of the present invention comprises: a socket, a sealing assembly, a plug, a limit block 4, an adjustment mechanism and a positioning mechanism. The socket and the plug can be electrically connected, the socket has a matching hole 102 for the plug to be plugged in, the sealing assembly is arranged on the socket, and the sealing assembly is used to seal the matching hole 102 when the plug and the socket are not connected to prevent impurities from entering the matching hole 102. The sealing assembly can also prevent impurities from entering the matching hole 102 along the gap between the plug and the socket when the plug and the socket are connected. The adjustment mechanism is used to drive the limit block 4 to move to achieve locking and fixing after the plug and the socket are plugged in, and prevent the plug and the socket from being disconnected during the connection process. The positioning mechanism is used for positioning during the plug-in process of the plug and the socket.

[0045] like Figures 1 to 3As shown, the socket includes a socket shell 101 and a socket contact 103. The socket shell 101 is a cylindrical structure. The socket contact 103 is fixed in the socket shell 101, and the socket contact 103 is coaxially arranged with the socket shell 101. A matching hole 102 is formed between the outer peripheral surface of the socket contact 103 and the inner wall of the socket shell 101. The front end of the socket contact 103 is used to electrically connect with the wire, and the rear end surface of the socket contact 103 is provided with a slot 104 for electrical connection. An insulating layer is provided on the outer peripheral surface of the socket shell 101. The insulating layer is made of rubber. The insulating layer forms a physical barrier on the outer peripheral side of the socket shell 101, thereby preventing the socket shell 101 from being electrically connected to other conductors, and can also protect the socket shell 101 and prevent the socket shell 101 from being damaged when it is impacted.

[0046] like Figure 2 As shown, the sealing assembly includes four flexible blades 2, which are fan-shaped structures. The arc edges of the four flexible blades 2 are fixedly connected to the opening of the matching hole 102, and the four flexible blades 2 are continuously distributed along the circumference of the matching hole 102. The flexible blades 2 are made of rubber and have good deformation ability. The four flexible blades 2 are assembled together to form a circular dustproof pad. At this time, the side walls between adjacent flexible blades 2 fit each other, thereby ensuring that the circular dustproof pad formed by the four flexible blades 2 can seal the matching hole 102 and realize the dustproof and waterproof function of the matching hole 102.

[0047] like Figures 3 to 6 As shown, the plug includes a plug shell 301 and a pin 302. The plug shell 301 is a cylindrical structure, and the pin 302 is fixedly inserted into the plug shell 301, and the pin 302 is coaxially arranged with the plug shell 301. The plug shell 301 includes a large diameter section 3011 and a small diameter section 3012 that are coaxially arranged. The outer diameter of the large diameter section 3011 is larger than the outer diameter of the small diameter section 3012, and the small diameter section 3012 is fixedly arranged at the front end of the large diameter section 3011. The outer diameter of the small diameter section 3012 is smaller than the aperture of the matching hole 102, and the small diameter section 3012 is used to be inserted into the matching hole 102. The front end of the pin 302 is used to be plugged into the slot 104 of the socket contact 103 to achieve electrical connection between the plug and the socket. The rear end of the pin 302 is used to be electrically connected to the plug wire. Four mounting holes 30111 are also provided on the outer circumferential surface of the large diameter section 3011 near the rear end, and the mounting holes 30111 are evenly spaced along the circumference of the large diameter section 3011, and each mounting hole 30111 extends along the radial direction of the large diameter section 3011. An insulating layer is provided on the outer surface of the plug housing 301, and the insulating layer is made of rubber.

[0048] When the plug is connected to the socket, the small diameter section 3012 is extended into the matching hole 102. The small diameter section 3012 pushes the flexible blades 2 to fold inward, thereby opening the circular structure formed by the four flexible blades 2. The flexible blades 2 are located between the small diameter section 3012 and the inner wall of the matching hole 102. One side of the flexible blades 2 is in close contact with the hole wall of the matching hole 102, and the other side is in close contact with the outer wall of the small diameter section 3012, thereby sealing the gap between the small diameter section 3012 and the matching hole 102, preventing dust and water from entering through the gap between the small diameter section 3012 and the hole wall of the matching hole 102, thereby causing poor contact between the pin 302 and the slot 104.

[0049] like Figures 4 to 7 As shown, four slide grooves 30121 are evenly spaced and distributed along the circumference of the small diameter section 3012 on the outer side wall of the small diameter section 3012 near the large diameter section 3011, and each slide groove 30121 is a triangular structure. The shape of the limit block 4 is adapted to the shape of the slide groove 30121, and a limit block 4 is slidably arranged in each slide groove 30121, and the side wall of the limit block 4 is in contact with the corresponding groove wall of the slide groove 30121, and the limit block 4 can move radially along the small diameter section 3012 to extend or retract into the slide groove 30121. The inner end of the limit block 4 is elastically connected to the bottom wall of the slide groove 30121 through the first elastic member 9, and the first elastic member 9 is a spring. When the first elastic member 9 is in a normal state, the limit block 4 is located in the slide groove 30121. An avoidance hole 30122 connecting the slide groove 30121 and the internal space of the small-diameter section 3012 is also provided on the bottom wall of each slide groove 30121 .

[0050] like Figures 4 to 6 , Figures 8 to 10As shown, the adjustment mechanism includes a rotating ring 71, a rotating shaft 72, a push rod 73, a connecting rod 10 and a limit assembly. The outer wall of the rotating ring 71 is provided with a plurality of grooves spaced apart along its circumference, and the grooves can increase the friction between the rotating ring 71 and the hands of the staff, so as to facilitate the staff to rotate the rotating ring 71. The rotating shaft 72 is coaxially arranged with the rotating ring 71, and the rotating shaft 72 is fixedly connected to the inner wall of the rotating ring 71 through the connecting rod 10, and four connecting rods 10 are evenly spaced along the circumference of the rotating shaft 72. Four push rods 73 are provided, and the four push rods 73 are fixedly connected to the front end of the rotating shaft 72, and each push rod 73 is arranged perpendicular to the rotating shaft 72, and each push rod 73 is evenly spaced along the circumference of the rotating shaft 72. The rotating shaft 72 and the four push rods 73 are rotatably inserted in the plug housing 301. The rotating shaft 72 is coaxially arranged with the plug housing 301. The four push rods 73 are respectively located in the four avoidance holes 30122. The four push rods 73 correspond to the four limit blocks 4 one by one. The rotating ring 71 is rotatably mounted on the large diameter section 3011, and the four connecting rods 10 are respectively located in the four mounting holes 30111. When the rotating ring 71 rotates, the rotating ring 71 can drive the connecting rods 10 and the push rods 73 to rotate synchronously. When the rotating shaft 72 rotates clockwise, the push rods 73 gradually approach the limit block 4 and stop against the inner end of the limit block 4. The push rods 73 can push the limit block 4 to overcome the pulling force of the first elastic member 9 and extend out of the slide groove 30121. When the rotating shaft 72 rotates counterclockwise, the push rods 73 gradually move away from the limit block 4. The limit block 4 is retracted into the slide groove 30121 under the action of the reset force of the first elastic member 9.

[0051] like Figure 3 , Figures 6 to 8 As shown, a sealing gasket 5 is fixedly arranged on the outer end surface of the limit block 4. The sealing gasket 5 is made of rubber and can fit with the inner wall of the matching hole 102. The shape of the sealing gasket 5 is adapted to the shape of the gap between the two adjacent flexible blades 2 folded inward. The cross section of the sealing gasket 5 is a triangular structure. The sealing gasket 5 has the same cross section as the limit block 4. Each side wall of the sealing gasket 5 is flush with the corresponding side wall of the limit block 4. When the limit block 4 extends out of the slide slot 30121, the sealing gasket 5 is located between the limit block 4 and the hole wall of the matching hole 102. The limit block 4 applies a thrust to the sealing gasket 5, thereby squeezing the sealing gasket 5 against the hole wall of the matching hole 102, so that the sealing gasket 5 is always in close contact with the matching hole 102. At the same time, when the small diameter section 3012 extends into the mating hole 102, the outer wall of the small diameter section 3012 squeezes the flexible blade 2 against the hole wall of the mating hole 102, so that the sealing gasket 5 is stuck between two adjacent flexible blades 2. The sealing gasket 5 cooperates with the flexible blade 2 to prevent a gap from being generated between the small diameter section 3012 and the mating hole 102, thereby preventing impurities such as dust and water from entering the mating hole 102 through the gap between the small diameter section 3012 and the mating hole 102 during the connection process, resulting in poor contact between the plug and the socket.

[0052] like Figures 6 to 8As shown, a long strip of filling pad 6 is fixed on the side wall of the limit block 4. The filling pad 6 is made of rubber and has good deformation ability. When the limit block 4 extends out of the slide slot 30121 and fits the flexible blades 2 on both sides thereof, the filling pad 6 is located between the limit block 4 and the corresponding flexible blade 2, and the filling pad 6 is deformed by squeezing, thereby preventing a gap from being generated between the limit block 4 and the flexible blade 2, preventing the limit block 4 from moving relative to the flexible blade 2, and thereby preventing the plug and the socket from shaking during the connection process.

[0053] When the small diameter section 3012 extends into the matching hole 102, the rotating ring 71 is rotated to drive the stopper 4 to extend out of the slide slot 30121, and the sealing gasket 5 is pressed against the hole wall of the matching hole 102. The two side walls of the stopper 4 can respectively fit with the two adjacent flexible blades 2, so that the stopper 4 can fit between the two flexible blades 2, thereby realizing the clamping connection between the socket housing 101 and the small diameter section 3012, thereby preventing the plug housing 301 from rotating relative to the socket housing 101, and preventing the small diameter section 3012 from moving backward and being withdrawn from the matching hole 102. At this time, the front end of the large diameter section 3011 abuts against the rear end of the socket housing 101, and can also prevent the plug housing 301 from moving forward, thereby realizing the fixation between the socket housing 101 and the plug housing 301.

[0054] like Figures 7 to 9 As shown, the limiting assembly includes a limiting rod 741, a second elastic member 11, and a limiting groove 742 provided on the inner end surface of the limiting block 4. The outer end of the push rod 73 is a hollow structure, and the limiting rod 741 is slidably mounted in the hollow structure of the push rod 73. The limiting rod 741 can move along the radial direction of the rotating shaft 72 and extend out of the push rod 73. The limiting rod 741 is elastically connected to the push rod 73 through the second elastic member 11, and the second elastic member 11 is a spring. The limiting groove 742 is an arc-shaped groove, and the outer end of the limiting rod 741 is an arc-shaped structure, and its curvature is the same as that of the limiting groove 742. When the limiting rod 741 is located in the hollow structure of the push rod 73, the second elastic member 11 is in a compressed state. When the rotating ring 71 drives the push rod 73 to rotate so that the push rod 73 is perpendicular to the inner end surface of the limiting block 4, the limiting rod 741 corresponds to the position of the limiting groove 742. At this time, the limiting rod 741 can extend outward from the push rod 73 under the elastic force of the second elastic member 11 and extend into the limiting groove 742, which can prevent the push rod 73 from continuing to rotate, and further prevent the push rod 73 from excessively rotating and losing contact with the limiting block 4, resulting in the limiting block 4 being retracted into the slide groove 30121 during the connection process, causing the connection between the plug and the socket to loosen. When disconnecting, first rotate the rotating ring 71 with force. The rotating ring 71 drives the rotating shaft 72 to rotate through the connecting rod 10, and the rotating shaft 72 drives the push rod 73 to rotate and move away from the limit block 4. During this process, the outer end of the limit rod 741 moves along the arc surface of the limit groove 742 and is squeezed out of the limit groove 742 under the action of external force.

[0055] like Figure 2 and Figure 5 As shown, the positioning mechanism includes positioning protrusions 81 and positioning grooves 82. The front end surface of the large diameter section 3011 is provided with a plurality of positioning protrusions 81, and the plurality of protrusions are evenly spaced along the circumference of the plug housing 301. The rear end surface of the socket housing 101 is provided with a plurality of positioning grooves 82, and the number of the positioning grooves 82 is the same as the number of the positioning protrusions 81, and the plurality of positioning grooves 82 are evenly spaced along the circumference of the socket housing 101. When all the positioning protrusions 81 extend into the positioning grooves 82, each stop block 4 is located between two adjacent flexible blades 2. The positioning protrusions 81 and the positioning grooves 82 enable the staff to accurately rotate the stop block 4 between the two flexible blades 2, thereby facilitating positioning.

[0056] The implementation principle of the camera connector of the embodiment of the present invention is: in the unconnected state, the four flexible blades 2 fit together to form a circular dustproof pad, which can close the mating hole 102 to prevent dust, water and other impurities from entering the mating hole 102, thereby blocking the slot 104 and causing poor contact between the pin 302 and the slot 104.

[0057] When the plug is connected to the socket, the staff holds the plug housing 301 and extends the small diameter section 3012 into the matching hole 102. During this process, the small diameter section 3012 squeezes the flexible blade 2 and pushes the flexible blade 2 forward, so that the flexible blade 2 flips and is located between the small diameter section 3012 and the inner wall of the matching hole 102. At this time, the flexible blade 2 can prevent the small diameter section 3012 from generating a gap between the small diameter section 3012 and the inner wall of the matching hole 102, and prevent dust, water and other impurities from entering the matching hole 102 through the gap between the small diameter section 3012 and the inner wall of the matching hole 102. After the small diameter section 3012 is extended into the matching hole 102, the pin 302 is inserted into the slot 104, so that the plug and the socket are electrically connected.

[0058] When the front end of the plug shell 301 stops contacting with the rear end of the socket shell 101, the plug shell 301 is rotated to make the positioning protrusion 81 extend into the positioning groove 82, and then the rotating ring 71 is rotated to make the rotating shaft 72 rotate clockwise, and the rotating shaft 72 drives the push rod 73 to rotate, and the push rod 73 gradually approaches the limit block 4 until it stops contacting with the limit block 4, and then the push rod 73 pushes the limit block 4 to extend out of the slide groove 30121, and the limit block 4 moves outward until the sealing gasket 5 is tightly attached to the inner wall of the matching hole 102. At this time, the push rod 73 is perpendicular to the inner end face of the limit block 4, and the limit block 4 is flush with the limit groove 742. Under the elastic force of the second elastic member 11, the limit rod 741 extends into the limit groove 742, thereby realizing the clamping connection between the push rod 73 and the limit groove 742. At the same time, when the limiting block 4 extends out of the sliding groove 30121 , the filling pad 6 is located between the limiting block 4 and the flexible blade 2 , thereby preventing a gap from being generated between the limiting block 4 and the flexible blade 2 .
