Summary of the invention

[0005] The present invention provides an antenna connector, aiming to solve the problem in the related art that it is difficult to avoid the phenomenon that a male head and a female head connected to each other become loose or even fall off from each other.

[0006] An antenna connector comprises a male head and a female head, wherein the female head comprises a shell 2, a protective layer 2 arranged in the shell 2 and a jack, wherein the male head comprises a shell 1 threadedly connected to the shell 2, a protective layer 1 rotatably arranged in the shell 1 and a pin arranged in the protective layer 1, wherein a sealing member and an outer gear ring are arranged on the inner side of the connecting end of the shell 2, and a piston rod for expanding the sealing member is slidably arranged on the connecting end of the shell 2; an inner gear ring is slidably arranged on the inner side of the connecting end of the shell 1 along its axial direction through an elastic member 1, an unlocking member is slidably arranged on the shell 1 along its axial direction through an elastic member 2, a driving member is slidably arranged in the shell 1 along the vertical direction, and the shell 1 is provided with a plurality of locking members, wherein the locking member ...

[0007] The present invention cooperates with the inner gear ring and the outer gear ring so that when shell one and shell two are firmly connected, shell one and shell two will not become loose or fall off from each other, thereby improving the stability of the connection between the male head and the female head. In addition, the inner gear ring and the outer gear ring can be locked or unlocked by toggling the unlocking piece, which is more convenient to operate.

[0008] Preferably, a slide groove 1 for sliding of the unlocking member and a slide groove 2 for sliding of the driving member are provided in the shell 1, and the storage slot is connected to the slide groove 1 and the slide groove 2.

[0009] Preferably, the magnetic attraction member is made of a neodymium magnet and is located directly above the second slide slot. The use of a neodymium magnet can ensure that the magnetic attraction member can stably adsorb the driving member.

[0014] Preferably, the guide member has an inclined driving surface and a blocking surface. When the ball stops downward against the driving surface, the inner gear ring can move away from the outer gear ring. The blocking surface helps to prevent the ball from escaping from the second slide groove.

[0015] Preferably, when shell one and shell two are in a locked state, the driving member abuts against the unlocking member under the action of the magnetic member, and the ball is restricted in the storage groove by the driving member; when shell one and shell two are in an unlocked state, the ball is located below the driving member.

[0016] Preferably, the piston rod is connected to the shell two via an elastic member three.

[0017] By adopting the above technical scheme, the present invention enables shell one and shell two to be connected more firmly through the cooperation of the inner gear ring and the outer gear ring, and when shell one and shell two are connected in place, shell one and shell two will be detached from each other; when the male head and the female head need to be separated, the unlocking piece can be used, and when shell one and shell two are in the locked state and when shell one and shell two are in the unlocked state, the dial ring is in a state of abutting against the end face of shell one, which is beneficial to avoid accidental unlocking of shell one and shell two due to accidental touching of the dial ring.

[0031] refer to Figure 2 , Figure 5 , Figure 6 as well as Fig. 9 A seal 23 and an outer gear ring 24 are fixedly provided on the inner side of the connecting end of the shell 20. The seal 23 is an annular airbag. The seal 23 is located between the protective layer 21 and the outer gear ring 24, and the inner ring side of the seal 23 is elastic. A piston rod 25 for expanding the seal 23 is slidably provided at the connecting end of the shell 20. The piston rod 25 is connected to the shell 20 through an elastic member 3 251. The elastic member 3 251 is specifically a spring. In the initial state and when the shell 10 does not stop against the piston rod 25, a certain amount of gas is stored in the seal 23.

[0032] refer to Figure 2-Figure 7 , Fig. 9 as well as Fig.10 The inner side of the connecting end of the shell 10 is provided with an annular slide plate 130 sliding along its axial direction. The end of the slide plate 130 facing the shell 20 is coaxially fixed with an inner gear ring 13 cooperating with the outer gear ring 24. The end of the slide plate 130 away from the shell 20 is connected to the shell 10 through an elastic member 131. The elastic member 131 is specifically a spring. The outer gear ring 24 has a plurality of teeth 1 241 along its circumference. The teeth 1 241 have a guide surface 1 2411. The inner gear ring 13 has a plurality of teeth 1 241 along its circumference. The tooth 132 has a guide surface 1321 matched with the guide surface 1 2411. The shell 10 is provided with an annular unlocking member 14 slidingly provided along its axial direction through an elastic member 141. The elastic member 141 is specifically a spring. The unlocking member 14 has a dial ring 142 at one end away from the shell 20. The shell 10 is provided with a slide groove 101 for sliding the unlocking member 14. In the initial state, under the action of the elastic member 141, the dial ring 142 stops against the end surface of the shell 10.

[0033] refer to Figure 2-Figure 5 , Figure 7 as well as Figure 8 A driving member 15 is provided in the shell 10 for sliding along the vertical direction, and a second slide groove 102 for sliding the driving member 15 is provided in the shell 10. A magnetic member 16 capable of attracting the driving member 15 is provided on the outer ring side of the unlocking member 14 on the shell 10. The magnetic member 16 adopts a neodymium magnet and is located directly above the second slide groove 102. A storage groove 103 is provided obliquely in the shell 10, and a freely movable ball 17 is provided in the storage groove 103. A guide member 18 cooperating with the ball 17 is fixedly provided on the outer ring side of the slide plate 130. In this embodiment, the storage groove 103 is connected with the first slide groove 101 and the second slide groove 102, and the storage groove 103 is away from the end of the second slide groove 102. Located on the side of the magnetic attraction member 16 away from the shell 20 and inclined toward the outside of the shell 10; the lower end of the driving member 15 has a fitting surface 151 that cooperates with the ball 17, and the upper end of the driving member 15 has an extrusion surface 152. The end of the unlocking member 14 close to the shell 20 has a fitting surface 143 that cooperates with the extrusion surface 152 of the driving member 15. In this embodiment, the fitting surface 151 and the extrusion surface 152 are respectively arc-shaped, and the guide member 18 has an inclined driving surface 181 and a blocking surface 182. When the ball 17 stops downward against the driving surface 181, the inner gear ring 13 can move in a direction away from the outer gear ring 24, so that the inner gear ring 13 and the outer gear ring 24 can be separated from each other.

[0034] Specific working principle: Reference Figure 1-Figure 10Taking the state where the magnetic member 16 is located directly above the shell 10 as an example, in the initial state and when the shell 10 is not connected to the shell 2 20, the unlocking member 14 is under the action of the elastic member 2 141, and the dial ring 142 on the unlocking member 14 stops against the end surface of the shell 10, and the unlocking member 14 blocks the upper end of the slide groove 2 102. Under the action of the magnetic member 16, the extrusion surface 152 of the driving member 15 stops upward against the inner ring side of the unlocking member 14, and the ball 17 is restricted in the storage groove 103 by the driving member 15.

[0035] Next, dock the connecting ends of shell 10 and shell 2 20, then hold shell 2 20 still with one hand, and rotate shell 10 clockwise (from right to left along the axial direction of unlocking piece 14) with the other hand to connect shell 10 and shell 2 20. During this process, the inner gear ring 13 gradually approaches the outer gear ring 24, shell 10 gradually stops against the piston rod 25, and the pin 12 can be inserted into the socket 22. When the inner gear ring 13 stops against the outer gear ring 24, as shell 10 continues to rotate clockwise, the elastic member 1 131 will be compressed, and when the tooth 2 132 is in contact with the two adjacent teeth 2 When the gaps between the inner and outer gear rings 13 and 24 correspond to each other, the elastic member 131 can push the inner gear ring 13 and the outer gear ring 24 to engage with each other. At this time, the shell 10 cannot rotate counterclockwise. Due to the cooperation between the guide surface 1 2411 and the guide surface 2 1321, the shell 10 can continue to rotate clockwise, so that the shell 10 and the shell 20 can be connected more firmly. The piston rod 25 can also be stopped by the shell 10, so that the seal 23 can expand and the inner ring side of the seal 23 can be tightly attached to the outer peripheral surface of the protective layer 11, thereby realizing the isolation of the connection part between the pin 12 and the jack 22 from the outside world.

[0036] When the shell 10 rotates clockwise to the limit position, it can stop. At this time, the shell 10 and the shell 2 20 are connected very firmly, and the inner gear ring 13 and the outer gear ring 24 are engaged with each other, so that the shell 10 and the shell 2 20 cannot be separated from each other.

[0037] When the male and female heads need to be separated, the male and female heads are rotated as a whole so that the magnetic member 16 is located directly above the shell 10, and then the dial ring 142 is pushed away from the shell 20 to make the unlocking member 14 break away from the cover on the upper end of the second slide groove 102. At this time, the magnetic member 16 can attract the driving member 15, so that the driving member 15 and the magnetic member 16 stop. At this time, the driving member 15 is free from the restriction on the ball 17 in the storage groove 103. The ball 17 will enter the second slide groove 102 under the action of gravity and be located below the driving member 15. At this time, the ball 17 is in contact with the driving surface 181. Then, the ring 142 is pushed toward the shell 20 so that the ring 142 and the end face of the shell 10 are stopped again. During this process, the unlocking member 14 can stop the extrusion surface 152 through the matching surface 143, so that the driving member 15 moves downward, so that the driving member 15 can squeeze the ball 17 through the fitting surface 151, so that the ball 17 can be smoothly pressed down, and then squeeze the driving surface 181, so that the inner gear ring 13 can move away from the outer gear ring 24 and disengage from the outer gear ring 24, and then the shell 10 can be rotated counterclockwise to separate the male head and the female head.

[0038] After the male head and the female head are separated, under the action of the elastic member 3 251, the piston rod 25 and the sealing member 23 return to their initial state.

[0039] Then, the male head is rotated so that the magnetic member 16 is located directly above the shell 10, and then the dial ring 142 is pushed outward so that the dial ring 142 and the end face of the shell 10 are disengaged from the stop, and the unlocking member 14 is free from blocking the upper end of the slide groove 102. At this time, the magnetic member 16 can attract the driving member 15, so that the driving member 15 and the magnetic member 16 are stopped, and then the connecting end of the shell 10 is adjusted to a vertically upward state. At this time, the ball 17 will move into the storage groove 103 again under the action of gravity, and then the dial ring 142 is pushed so that the dial ring 142 and the end face of the shell 10 are stopped again. At this time, under the action of the magnetic member 16, the extrusion surface 152 of the driving member 15 is stopped upward against the inner ring side of the unlocking member 14, and the ball 17 is restricted in the storage groove 103 by the driving member 15 and returns to its initial state.

[0040] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
