This kind of connector is designed for high-end microphone such as condenser microphone, and is also suitable for the connection of other professional audio equipment. In the structure of card nong connector, the female head is clamped by the sliding friction of the button and the partial surface of the grounding sheet spring. However, due to the defects of the sliding surface process of the button and the shell, the sliding may not be smooth, which may cause the problem of button jamming.

[0003] In view of the above problems, in the prior art, for example, the card nong connector female head disclosed in Chinese utility model patent (authorized publication number CN211829406U) has the structure including a shell, a button is arranged on the shell, both ends of the button extend into the shell, wherein the left end of the button is movably connected with the shell, and the right end is mutually buckled with the shell. In particular, the right lower end of the button is designed as a circular arc surface to optimize the motion trajectory. In addition, an inner core is inserted on one side of the shell, and a grounding spring sheet is arranged on the inner core. The patent increases the circular arc of the grounding spring sheet, so that the grounding spring sheet and the button are connected by circular arc transition, so that the motion trajectory of the button has a forward inclination, which improves the clamping efficiency, reduces the additional friction, and makes the disassembly and maintenance more convenient.

[0004] However, although the prior art has improved in avoiding button jamming, there is still a problem that the wire connected to the connector female head is easy to be damaged. In the use process, the part of the wire will be constantly bent, and after long time use, the wire core inside the wire is easy to break, which affects the transmission quality of the signal. Since the cost of replacing the wire core is high, this not only increases the maintenance cost, but also may adversely affect the continuous use of the equipment. UTILITY MODEL CONTENTS

DETAILED DESCRIPTION

[0024] In order to further understand the characteristics, technical means and specific purposes and functions achieved by the utility model, the utility model will be described in further detail below in combination with the drawings and specific embodiments.

[0025] Referring to Figures 1-7 The utility model provides a cardon connector female head structure, including plug body 1, main body 3 and shell 4, plug body 1 is the core part of connector, is usually used to insert into the corresponding male head, realizes the transmission of electric signal. One end of main body 3 is connected with plug body 1, and the other end of main body 3 is provided with external thread, and the inner wall of shell 4 is provided with internal thread, and main body 3 is connected with shell 4 through thread, and one end of main body 3 away from plug body 1 is provided with wire fixing device 7.

[0026] Wire fixing device 7 includes a plurality of wire pressing blocks 71 installed on main body 3, a wire hole 711 is formed in each wire pressing block 71, and a wire pressing bolt 712 is rotatably arranged on the wire pressing block 71, when the wire core of the wire is inserted into the wire hole 711, the wire pressing bolt 712 is used to fix the wire in the wire pressing block 71.

[0027] The shell 4 is removed from the connector female head, then the wire core of the broken wire is accurately inserted into the wire hole 711, then the wire is firmly fixed by rotating the wire pressing bolt 712 and using the pressure generated by the wire pressing bolt 712. After this series of operations are completed, the reconnection of the wire is successfully realized. Therefore, the user does not need to replace the entire cardon connector female head due to the wire breakage, thereby reducing the maintenance cost and improving the operation convenience.

[0028] A clamping sleeve 5 for fixing the wire is slidably arranged in the shell 4, the clamping sleeve 5 is a sliding component arranged inside the shell 4, for clamping and fixing the wire. One end of the clamping sleeve 5 is provided with a plurality of elastic clamping claws 51, the elastic clamping claw 51 is a key component on the clamping sleeve 5, the elastic clamping claw 51 has a certain elasticity and restoring force. When the wire is inserted into the clamping sleeve 5, the elastic clamping claw 51 detects the outside of the wire, each elastic clamping claw 51 tilts towards the center of the clamping sleeve 5, the elastic clamping claw 51 is connected with a connecting block 52, and the side surface of the connecting block 52 close to the elastic clamping claw 51 is inclined, the shell 4 is further provided with a stop ring 41, the position close to the connecting block 52 is inclined, when the inclined surface of the connecting block 52 contacts with the inclined surface of the stop ring 41, the connecting block 52 makes the elastic clamping claw 51 tighten towards the center of the clamping sleeve 5.

[0029] When the user inserts the wire into the clamping sleeve 5, the elastic clamping claws 51 will be opened outward due to their elasticity, adapting to the diameter of the wire. The user continues to pull the clamping sleeve 5, making it slide along the inside of the shell 4. When the clamping sleeve 5 slides to a certain position, the inclined surface of the connecting block 52 will be in contact with the inclined surface of the stop ring 41. Due to the design of the inclined surface, the connecting block 52 will be pushed by the stop ring 41, moving towards the center of the clamping sleeve 5. The movement of the connecting block 52 towards the center will cause the elastic clamping claws 51 to tighten, thereby clamping the wire. At this time, the wire is firmly fixed in the clamping sleeve 5, achieving stable clamping of the wire.

[0030] The shell 4 is fixed with a sliding block 42 near one end of the clamping sleeve 5, and the clamping sleeve 5 is also provided with a sliding groove 53 that slides with the sliding block 42. The clamping sleeve 5 is clamped with a clamping piece 6 for fixing the clamping sleeve 5 between the shell 4 and the clamping sleeve 5. Through the cooperation of the sliding groove 53 and the sliding block 42, the clamping sleeve 5 can slide smoothly inside the shell 4.

[0031] The clamping piece 6 is elastic to facilitate clamping between the shell 4 and the clamping sleeve 5. The joint of the plug body 1 and the main body 3 is slidingly provided with a buckle 2, and the plug body 1 and the main body 3 are also provided with a spring for making the buckle 2 rebound.

[0032] The plug body 1 is also provided with a plurality of insertion holes 11, and a limiting groove 12 is formed along the length direction at the edge of the plug body 1.

[0033] Working principle: first, the shell 4 is taken off from the main body 3, for the next wire connection preparation. Then, the wire to be connected is inserted into the shell 4, and the wire core is accurately inserted into the preset wire hole 711 position of the wire pressing block 71. Then, by rotating the wire pressing bolt 712, the wire core is firmly fixed on the wire pressing block 71 by the pressure generated by the wire pressing bolt 712, thereby completing the wire connection work. This design enables users to repair the wire connection by themselves after the wire is broken, without replacing the entire female connector, greatly reducing the maintenance cost. After completing the connection, the user needs to reinstall the shell 4 back to the main body 3. At this time, by pulling the clamping sleeve 5, the elastic clamping claw 51 and the connecting block 52 on it cooperate with the stop ring 41 in the shell 4 to further fix the wire. Specifically, since the stop ring 41 and the connecting block 52 are designed as inclined surfaces, when the clamping sleeve 5 moves in the shell 4, the inclined surface of the connecting block 52 will contact and interact with the inclined surface of the stop ring 41. With the continuous movement of the clamping sleeve 5, the connecting block 52 will push the elastic clamping claw 51 to tighten towards the center of the clamping sleeve 5, thereby achieving firm clamping of the wire. In order to ensure the stable fixation of the wire, the user also needs to clamp the clamping piece 6 between the shell 4 and the clamping sleeve 5. This step further enhances the fixation effect of the wire, effectively avoiding the problem of wire separation caused by wire pulling. Finally, the female connector with completed connection and fixation work is inserted into the corresponding equipment, and normal use can be started. The entire operation process is simple and convenient, without the need for professional tools or skills, greatly improving the operation experience of the user and the reliability of the equipment.
