[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] like Figure 1-6 As shown, a radio frequency cable adapter includes a cable;

[0029] A female head 1 is fixedly provided at the first end thereof, and a plurality of boring holes are opened on the female head 1;

[0030] A male head 2 is fixedly arranged at the second end thereof, and a plurality of easily deformable arc plates 22 are fixedly arranged on the male head 2. The easily deformable arc plates 22 are bent as the female head 1 and the male head 2 approach each other. In the bent state, the clamping piece 25 arranged on the easily deformable arc plates 22 is clamped with the boring hole.

[0031] Wherein: a plug pin 21 is arranged in the male connector 2, and an equidistant spring is arranged on the plug pin 21; a socket 11 which is plugged and matched with the plug pin 21 is arranged in the female connector 1.

[0032] Specifically, the male connector 2 and the female connector 1 are both insulating plastic parts to avoid leakage during use. The pin 21 of the male connector 2 corresponds to the socket 11 of the female connector 1 and is plugged in, so that the deformable arc plate 22 moves along the axial direction of the female connector 1 to the inside of the female connector 1, as shown in FIG. Figure 5 As shown, at this time, the clamp 25 is abutted by the inner wall of the female head 1, and will not affect the movement of the male head 2, until the end of the easily deformable arc plate 22 abuts against the socket 11, and the easily deformable arc plate 22 is bent under the force, as shown in FIG. Figure 6As shown, at this time, the clamp 25 is located in the boring, and the clamp 25 extends outward along the tangent direction of the bent portion of the easily deformable arc plate 22, so that the clamp 25 and the boring are engaged with each other. At the same time, the easily deformable arc plate 22 is still in a bent state and has a certain deformation potential energy. The deformation potential energy is transmitted along the end of the easily deformable arc plate 22 to the socket 11, so that the socket 11 has a reaction force on the pin 21 and the easily deformable arc plate 22. Combined with the elastic potential energy of the equidistant spring on the pin 21, the socket 11 and the pin 21 are tightly attached to each other to avoid loosening; when the adapter needs to be removed, the male head 2 continues to be moved axially along the female head 1, and the pin 21 still remains engaged with the socket 11. The equidistant spring contracts, and the easily deformable arc plate 22 is further deformed. The clamp 25 is impacted by the edge of the boring and disengaged from the boring, and the clamp 25 is no longer engaged with the boring, and the male head 2 and the female head 1 are disengaged from each other.

[0033] In the above technology, the deformable arc plate 22 moves along the axial direction of the female head 1 to the inside of the female head 1, and bends under the action of force, so that the clamp 25 and the boring hole are engaged with each other and will not slip. At the same time, the deformable arc plate 22 is still in a bent state and has a certain deformation potential energy. The deformation potential energy is transmitted along the end of the deformable arc plate 22 to the socket 11, so that the socket 11 has a reaction force on the pin 21 and the deformable arc plate 22. The socket 11 and the pin 21 are tightly attached to each other to avoid looseness, which is conducive to the stable transmission of signals.

[0034] As an embodiment further provided by the present invention, a protrusion is provided on the insertion hole 11, and a guide sliding surface 23 that contacts the protrusion is provided on the first end of the easily deformable arc plate 22.

[0035] Specifically, the first end of the easily deformable arc plate 22 is in conflict with the socket 11, and the position of the first end of the easily deformable arc plate 22 is limited by the setting of the protrusion, and the guide surface 23 slides along the surface of the protrusion. At this time, the force of the protrusion on the easily deformable arc plate 22 is transmitted along the normal direction of the protrusion, so that the easily deformable arc plate 22 is bent as shown in FIG. Figure 6 As shown, the middle part of the deformable arc plate 22 swells and abuts against the inner cavity of the female head 1 .

[0036] As another embodiment further provided by the present invention, a hollow groove 24 is provided on the deformable arc plate 22 , and the first end of the clamp 25 is fixedly disposed in the hollow groove 24 .

[0037] Specifically, the hollow groove 24 is conducive to air circulation inside the male head 2, allowing the retained moisture to evaporate, while making the deformable arc plate 22 easier to bend, and the hollow groove 24 can accommodate the clamping member 25 when the clamping member 25 is resisted by the inner wall of the female head 1.

[0038] As another embodiment further provided by the present invention, an elastic member 26 for driving the second end of the clamping member 25 to pop outward is disposed in the hollow groove 24 .

[0039] Specifically, the elastic member 26 makes the second end of the clamp 25 tend to pop outward. Figure 5 As shown, when the clamp 25 is resisted by the inner wall of the female head 1, the clamp 25 shrinks into the hollow groove 24. At this time, the elastic member 26 stores elastic energy. When the clamp 25 moves to the bottom of the boring hole, it is no longer blocked. The elastic potential energy of the elastic member 26 is released, driving the second end of the clamp 25 to engage with the boring hole.

[0040] As another embodiment further provided by the present invention, a sealing sleeve 3 is movably provided on the female head 1. The sealing sleeve 3 is a hollow frustum-shaped structure, including a wide portion and a narrow portion.

[0041] Specifically, the sealing sleeve 3 covers the boring of the female connector 1 to prevent moisture from entering the inside of the adapter through the boring, and protects the connection part. The initial position of the sealing sleeve 3 is as follows: Figure 5 As shown, at this time, the boring hole corresponds to the inner wall of the wide part, and the clamping piece 25 will not be interfered by the sealing sleeve 3 during the clamping process with the boring hole. When the connection needs to be released, the male head 2 is moved close to the female head 1 along the axial diameter direction, and the equidistant spring contracts, and the clamping piece 25 is separated from the boring hole and retracted into the hollow groove 24. Figure 6 Taking the direction shown as a reference, slide the sealing sleeve 3 to the right so that the narrow portion corresponds to the boring hole and fits closely to the boring hole, thereby preventing the clamping member 25 from sliding back into the boring hole during the rightward movement.

[0042] As another embodiment further provided by the present invention, a limiting groove 31 for retaining the clamping member 25 is provided on the inner wall of the sealing sleeve 3 .

[0043] Specifically, when the clamping member 25 is engaged with the boring hole, Figure 6 The sealing sleeve 3 is slid rightward with the direction shown as a reference, so that the limiting groove 31 corresponds to the second end of the clamping member 25, and the clamping member 25 is retained in the limiting groove 31 to prevent the clamping member 25 from sliding or being loosened by external collision.

[0044] Working principle: Both the male connector 2 and the female connector 1 are made of insulating plastic to prevent leakage during use. The pin 21 of the male connector 2 is aligned with the socket 11 of the female connector 1 and plugged in, so that the deformable arc plate 22 moves along the axial direction of the female connector 1 to the inside of the female connector 1, as shown in FIG. Figure 5 As shown, at this time, the clamp 25 is abutted by the inner wall of the female head 1, and will not affect the movement of the male head 2, until the end of the easily deformable arc plate 22 abuts against the socket 11, and the easily deformable arc plate 22 is bent under the force, as shown in FIG. Figure 6 As shown, at this time, the clamp 25 is located in the boring hole, and the sealing sleeve 3 is always located in the above process. Figure 5In the initial position shown, the boring hole corresponds to the inner wall of the wide portion. The clamping piece 25 will not be interfered by the sealing sleeve 3 during the clamping process with the boring hole. The elastic piece 26 makes the second end of the clamping piece 25 tend to pop outward, and the clamping piece 25 extends outward along the tangent direction of the bent portion of the easily deformable arc plate 22, so that the clamping piece 25 and the boring hole are clamped with each other. At the same time, the easily deformable arc plate 22 is still in a bent state and has a certain deformation potential energy. The deformation potential energy is transmitted along the end of the easily deformable arc plate 22 to the socket 11, so that the socket 11 has a reaction force on the pin 21 and the easily deformable arc plate 22. Combined with the elastic potential energy of the equidistant spring on the pin 21, the socket 11 and the pin 21 are tightly attached to each other to avoid loosening. Then, Figure 6 The sealing sleeve 3 is slid rightward with the direction shown as a reference, so that the limiting groove 31 corresponds to the second end of the clamping piece 25, and the clamping piece 25 is retained in the limiting groove 31 to prevent the clamping piece 25 from sliding or being loosened by external collision; when the adapter needs to be removed, the male head 2 is continued to be moved axially along the female head 1, the pin 21 is still connected with the socket 11, the equidistant spring contracts, the deformable arc plate 22 is further deformed, the clamping piece 25 is resisted by the edge of the boring hole and disengaged from the boring hole, the clamping piece 25 is disengaged from the boring hole and retracted into the hollow groove 24, and at this time Figure 6 Taking the direction shown as a reference, slide the sealing sleeve 3 to the right so that the narrow portion corresponds to the boring hole and fits tightly against the boring hole, preventing the clamping member 25 from sliding back into the boring hole during the movement to the right. The clamping member 25 is no longer engaged with the boring hole, and the male head 2 and the female head 1 are separated from each other.

[0045] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
