Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a stable BNC connector. Background Technology

[0002] BNC connectors are a common type of radio frequency connector, widely used in video, audio, wireless communication, security monitoring, broadcasting and television, and other fields. They are mainly used to transmit radio frequency signals. BNC connectors mainly consist of a male and a female connector. The male connector has a bayonet groove, and the female connector has a protrusion. When connecting the male and female connectors, align the bayonet groove with the protrusion, insert the male and female connectors together, and then rotate the male connector to connect them. To disconnect, rotate the male connector in the opposite direction to separate them.

[0003] When existing BNC connectors are accidentally rotated by external force, the male and female ends are easily separated, causing connection failure and making the connection unstable. Utility Model Content

[0004] The purpose of this invention is to provide a stable BNC connector to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stable BNC connector, comprising a connector body, a bayonet groove and a circular groove on the outer side wall of the connector body, a notch at one end of the connector body, the notch, the bayonet groove and the circular groove being connected, a locking ring being slidably mounted on the outer side of the connector body, a stop block integrally formed on one side of the locking ring, a transverse groove on the outer side of the connector body, the transverse groove being connected to the bayonet groove, the stop block being slidably mounted in the transverse groove, a spring piece being mounted on the outer side of the connector body, a plurality of elastic feet distributed in a ring at equal intervals on one side of the spring piece, one end of the elastic feet abutting against the locking ring.

[0006] As a preferred embodiment of this utility model, the side of the stop block away from the circular groove is provided with an inclined surface.

[0007] As a preferred embodiment of this utility model, a limiting block is provided on the outer side of the connector body.

[0008] As a preferred embodiment of this utility model, the connector body is provided with a clearance groove corresponding to the elastic foot.

[0009] As a preferred embodiment of this utility model, the outer side of the locking ring is provided with anti-slip texture.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: the locking ring and the stop block of this utility model can block the protrusion on the female head, prevent the connector body from being accidentally rotated, causing the connector body to separate from the female head, and ensure the stable connection between the connector body and the female head. In addition, the elastic foot of the utility model applies a pushing force to the locking ring, so that the stop block is always in the bayonet groove, which plays a blocking role against the protrusion on the female head and improves reliability.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1 to 6This utility model provides a technical solution: a stable BNC connector, including a connector body 1, which is the male connector of the BNC connector. The female connector is existing technology and will not be described in detail. The outer side wall of the connector body 1 has a bayonet groove 2 and a circular groove 4. One end of the connector body 1 has a notch 3. When the connector body 1 is connected to the female connector, the protrusion on the female connector enters the bayonet groove 2 through the notch 3. Then, the connector body 1 rotates a certain angle so that the protrusion on the female connector enters the circular groove 4, thus realizing the connection between the connector body 1 and the female connector. The notch 3, the bayonet groove 2, and the circular groove 4 are connected. A locking ring 6 is slidably installed on the outer side of the connector body 1. A stop 8 is integrally formed on one side of the locking ring 6. The stop 8 is used to block the protrusion on the female connector, preventing it from moving from the circular groove 4. Within the bayonet groove 2, the connector body 1 separates from the female head, ensuring a stable connection between the connector body 1 and the female head. A transverse groove 12 is provided on the outer side of the connector body 1. If it is necessary to separate the connector body 1 from the female head, simply push the locking ring 6. The locking ring 6 drives the stop block 8 to move until the stop block 8 moves completely into the transverse groove 12. Then, the connector body 1 can be rotated to separate it from the female head. The transverse groove 12 is connected to the bayonet groove 2. The stop block 8 is slidably installed in the transverse groove 12. A spring piece 5 is installed on the outer side of the connector body 1. One side of the spring piece 5 is provided with multiple elastic feet 7 distributed in a ring at equal intervals. The elastic feet 7 have a certain elasticity to apply a pushing force to the locking ring 6, so that the stop block 8 is always in the bayonet groove 2 without external force, which plays a blocking role against the protrusion on the female head. One end of the elastic foot 7 abuts against the locking ring 6.

[0020] The stop block 8 has an inclined surface 13 on the side away from the circular groove 4. When the protrusion on the female head enters the bayonet groove 2, the protrusion presses against the inclined surface 13, causing the stop block 8 to move away from the bayonet groove 2. This allows the connector body 1 to be connected to the female head without having to push the locking ring 6, thus improving the ease of operation.

[0021] The connector body 1 has a limiting block 9 on its outer side. The limiting block 9 is used to limit the locking ring 6, preventing the locking ring 6 from moving to the outside of the bayonet groove 2, and also preventing the stop block 8 from completely separating from the transverse groove 12, which would cause the locking ring 6 to rotate.

[0022] The connector body 1 has a relief groove 10 corresponding to the elastic foot 7. The relief groove 10 is used to avoid the elastic foot 7, so that the elastic foot 7 can deform normally and will not be blocked by the connector body 1.

[0023] The locking ring 6 has anti-slip texture 11 on its outer side. The anti-slip texture 11 is used to increase friction so that it is not easy to slip when the locking ring 6 is turned.

[0024] Specifically, when the connector body 1 is connected to the female head, the notch 3 is aligned with the protrusion on the female head, allowing the connector body 1 to be inserted into the female head. The protrusion on the female head enters the bayonet groove 2 along the notch 3. Then, the connector body 1 is rotated so that the protrusion on the female head enters the circular groove 4, thus achieving the connection between the connector body 1 and the female head. When the connector body 1 is accidentally touched and tends to rotate, the protrusion on the female head is blocked by the stop block 8, so the connector body 1 cannot rotate, thereby ensuring a stable connection between the connector body 1 and the female head. When it is necessary to separate the connector body 1 from the female head, the locking ring 6 is pushed to move away from the bayonet groove 2. The locking ring 6 drives the stop block 8 to move. When the stop block 8 completely leaves the bayonet groove 2, the protrusion on the female head is no longer blocked by the stop block 8. The connector body 1 is rotated so that the protrusion on the female head is aligned with the notch 3, and then the connector body 1 can be separated from the female head.
