[0017] Reference Figures 1 to 4 As shown, the utility model provides a quick-locking metal BNC connector, including: a connector body 1, an end face of the connector body 1 is provided with a plug-in slot, a plug-in pin 3 is fixedly connected in the plug-in slot, guide slots 2 are symmetrically provided on both sides of the plug-in slot, and an engaging slot 5 is provided in the middle of the side of the guide slot 2, and a spring is fixedly connected to the end of the guide slot 2 away from the opening, and a main slide slot 11 is provided on the side of the guide slot 2 away from the plug-in slot, and the two ends of the main slide slot 11 are respectively fixedly connected to a moving block 7 and a limiting plate 4, and the limiting plate 4 is slidably connected in the guide slot 2, the moving block 7 is slidably connected to the outer side of the connector body 1, and the end of the outer side of the connector body 1 away from the plug-in slot is fixedly connected to a fixing ring 10.

[0018] In this embodiment, the metal BNC connector body 1 is engaged with the corresponding connector seat (not shown in the figure), wherein the bayonet on the outer side of the connector seat is embedded in the corresponding guide groove 2. During the embedding process of the pin 3 of the connector body 1, the bayonet will gradually move along the length direction of the guide groove 2 to the opening of the fitting groove 5, and the bayonet will push the limit plate 4 at the opening of the fitting groove 5 to move, so that the limit plate 4 can squeeze the corresponding spring, and then the connector body 1 is rotated so that the bayonet of the connector seat can be smoothly embedded in the fitting groove 5. At this time, the limit plate 4 can be reset under the action of the squeezed spring after losing the obstruction of the bayonet, so the limit plate 4 can press the bayonet in the fitting groove 5. The fast locking and fixing prevents the problem of accidental disengagement of the bayonet due to external force interference on the metal BNC connector body 1, thereby ensuring the stability of the connection between the metal BNC connector body 1 and the connector base. When the connection between the connector body 1 and the connector base needs to be released, the worker only needs to clamp the two sets of moving blocks 7 at the same time and move the moving blocks 7 in the direction of the fixed ring 10, so that the moving blocks 7 can drive the limit plate 4 to move synchronously through the fixed blocks 6, and the limit plate 4 leaves the opening of the fitting groove 5 and squeezes the spring. The worker reverses the connector body 1 through the moving blocks 7 to disengage the bayonet from the fitting groove 5. At this time, the connector body 1 can be quickly pulled out to complete the disassembly of the two.

[0019] As a preferred embodiment, the fixing ring 10 is in a circular ring structure, the outer arc surface of the fixing ring 10 is in an arc-shaped structure, and the outer arc surface of the fixing ring 10 is circumferentially surrounded by multiple groups of anti-slip strips 9 fixedly connected at equal intervals, and the anti-slip strips 9 are in a fan-shaped structure.

[0020] In this embodiment, if Figure 1 and Figure 3 The setting of the arc surface structure of the fixing ring 10 can enhance the stability of the worker's grip and push the connecting head body 1 to engage with the connecting seat, and can reduce the chance of the worker's hand slipping. In addition, the setting of the anti-slip strip 9 can ensure that the worker can stably rotate the leveling head and ensure that the pin can be smoothly embedded in the engaging groove 5.

[0021] As a preferred embodiment, the two groups of guide grooves 2 symmetrically opened inside the connector body 1 are both long strip structures, and the length of the guide groove 2 is greater than the axial length of the plug-in groove. At the same time, the axial cross-section formed by the guide groove 2 and the plug-in groove together is a concave structure.

[0022] In this embodiment, if Figure 1 , Figure 2 and Figure 3 The structural setting of the guide groove 2 enables the latch to move in a directional manner in the plug-in groove, and the guide groove 2 can also be fixed with a connecting spring, so that the limit plate 4 has an automatic reset effect after being pushed.

[0023] As a preferred embodiment, the main slide groove 11 opened on the surface of the guide groove 2 has a rectangular structure, the width of the main slide groove 11 is smaller than the width of the guide groove 2, and the length of the main slide groove 11 is smaller than the length of the guide groove 2. At the same time, the cross-section formed by the guide groove 2 and the main slide groove 11 combined together has an L-shaped structure.

[0024] In this embodiment, if Figure 1 , Figure 2 and Figure 3 The size of the main slide groove 11 is smaller than that of the guide groove 2, so the probability of the spring in the guide groove 2 being stuck in the main slide groove 11 can be effectively reduced, thereby ensuring that the spring can smoothly complete the compression and reset process.

[0025] As a preferred embodiment, two sets of engaging grooves 5 are centrally symmetrically arranged inside the connector body 1, and both sets of engaging grooves 5 are fan-shaped structures, and one end of the engaging groove 5 is connected to the corresponding guide groove 2, and the engaging groove 5 and the guide groove 2 are combined to form a T-shaped structure.

[0026] In this embodiment, if Figure 1 , Figure 2 and Figure 3 The structural arrangement of the engaging groove 5 and the guide groove 2 enables the bayonet pin slidably connected in the guide groove 2 to be smoothly embedded in the engaging groove 5, thereby realizing the engaging connection between the connector body 1 and the connecting seat, and enhancing the stability of the connection between the connector body 1 and the connecting seat.

[0027] As a preferred embodiment, the limit plate 4 has a rectangular structure, the sizes of the limit plate 4 and the guide groove 2 are matched, and the surface of the limit plate 4 is fixedly connected to the fixed block 6 relative to the main slide groove 11, and the fixed block 6 has a square structure. At the same time, the limit plate 4 and the main slide groove 11 are combined together to form an L-shaped structure.

[0028] In this embodiment, if Figure 1 , Figure 2 and Figure 3 The sizes of the limit plate 4 and the guide groove 2 are adapted to each other, which can not only enhance the stability of the limit plate 4 when moving, but also prevent the limit plate 4 from accidentally embedding into the main slide groove 11. At the same time, the sizes of the fixed block 6 and the main slide groove 11 are adapted to each other, which can limit the movement range of the limit plate 4, avoid excessive extrusion of the spring, and ensure the service life of the spring.

[0029] As a preferred embodiment, the moving block 7 has a right-angled trapezoidal structure, the side of the moving block 7 close to the outer side of the connector body 1 has an arc-shaped structure, and the edges of the moving block 7 are all arc-shaped structures, and the inclined surface of the moving block 7 is fixedly connected to the friction layer 8 by a groove, and the friction layer 8 has a square structure, and a plurality of anti-skid grooves are evenly arranged on the surface of the friction layer 8, and the cross-section of the anti-skid grooves has an isosceles trapezoidal structure.

[0030] In this embodiment, if Figure 1 , Figure 2 and Figure 3 The inclined structure of the moving block 7 can enhance the comfort and stability of the workers when pushing the moving block 7, and the friction layer 8 can be made of soft rubber material. The anti-skid grooves on the surface of the friction layer 8 can further enhance the anti-skid effect, thereby ensuring that the workers can push the moving block 7 to move stably, and can also drive the connecting head body 1 to rotate through the moving block 7.

[0031] The quick-locking metal BNC connector of the utility model cooperates with the moving block 7, the fixing block 6, the spring and the limiting plate 4 so that after the connector is engaged and connected, the limiting plate 4 can effectively limit the movement of the bayonet pin, thereby realizing the quick locking and fixing of the metal BNC connector, thereby effectively avoiding the connection problems of poor contact or disconnection of the connector.
