Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1

[0023] See also Figures 1 to 3 As shown, the utility model provides an MMCX type straight cable connector, including a shell 1, a solder tail 2 and a pin 3. A supporting medium 14 is provided inside the shell 1 for supporting and fixing the pin 3. The pin 3 is arranged inside the supporting medium 14. A screw sleeve 16 is provided at the end of the shell 1 away from the solder tail 2 through a clamping ring 15. The inner wall of the solder tail 2 is connected to a cable body 17 by soldering. The core wire end of the cable body 17 is soldered to one end of the pin 3.

[0024] A first arc-shaped clamp 4 is provided at the top of the surface of the housing 1, and a second arc-shaped clamp 5 is provided at the bottom of the surface of the housing 1. A clamp rod 6 is fixedly connected to the inner side of each of the first arc-shaped clamp 4 and the second arc-shaped clamp 5. The clamp rod 6 passes through the housing 1 and extends to the interior of the solder tail 2. The first arc-shaped clamp 4 is fixedly connected to the second arc-shaped clamp 5 via a clamping assembly.

[0025] The clamping assembly includes two fixing rods 7 arranged above the second arc-shaped clamp 5. The front and rear sides of the second arc-shaped clamp 5 are both provided with protrusions. The fixing rods 7 are fixed to the top of the protrusions. A through slot 8 is opened inside the fixing rod 7, and baffles 9 are slidably connected on both sides of the inner wall of the through slot 8. The baffles 9 can prevent the spring 10 from popping out of the through slot 8. A spring 10 is fixedly connected between the two baffles 9. A protrusion 11 is fixedly connected to the opposite side of the two baffles 9. The protrusion 11 can enter and exit the through slot 8 under the elastic force of the spring 10, so as to facilitate the assembly and disassembly between the first arc-shaped clamp 4 and the second arc-shaped clamp 5.

[0026] The top and the bottom of the shell 1 and the solder tail 2 are both provided with through holes 12 adapted to the clamping rod 6. The front and rear sides of the first arc-shaped clamp 4 are fixedly connected with extension blocks 13. The surface of the extension block 13 is provided with a fixing hole adapted to the fixing rod 7. The top of the fixing rod 7 passes through the outside of the extension block 13, and the bottom of the protrusion 11 is movably connected to the top of the extension block 13.

[0027] Through the setting of the above structure, the clamping assembly fixes the first arc clamp 4 and the second arc clamp 5 to the outside of the shell 1, and the clamping rod 6 enters the solder tail 2, which can fix the shell 1 and the solder tail 2. Conversely, the protrusion 11 is pressed into the through groove 8 to separate the first arc clamp 4 and the second arc clamp 5, thereby facilitating the separation of the solder tail 2 from the connector shell 1. The operation is simple and quick, and no external special tools are required, which saves time and effort, improves the efficiency of disassembly and assembly, and is beneficial to subsequent maintenance.

[0028] Example 2

[0029] Based on Example 1, please refer to Figure 1 and Figure 4 As shown, a plurality of heat conducting plates 18 are fixedly connected to the surface of the shell 1, and the plurality of heat conducting plates 18 are distributed in a ring shape on the surface of the shell 1, and a plurality of heat absorbing rods 19 that penetrate into the interior of the shell 1 are fixedly connected to the inner side of the heat conducting plates 18. The heat conducting plates 18 and the heat absorbing rods 19 are made of graphite material, which has good thermal conductivity and is convenient for absorbing and releasing the heat inside the shell 1. A heat dissipation channel 20 is opened inside the heat absorbing rods 19.

[0030] Through the above-mentioned structural setting, the heat dissipation channel 20 can conduct the heat inside the shell 1 to the heat conducting plate 18, and the external heat conducting plate 18 is convenient for dissipating the heat, thereby cooling and dissipating the temperature inside the cable connector and extending the service life of the device.

[0031] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0032] When in use, the first arc clamp 4 and the second arc clamp 5 are fixed to the outside of the shell 1, and the clamping rod 6 enters the through hole 12 on the surface of the solder tail 2. When the first arc clamp 4 and the second arc clamp 5 are assembled, the protrusion 11 is pressed into the through groove 8 of the fixing rod 7, and then the fixing rod 7 passes through the extension block 13 on the first arc clamp 4. Under the reaction force of the spring 10, the protrusion 11 pops out of the fixing rod 7, which can fix the shell 1 and the solder tail 2. On the contrary, after the protrusion 11 is pressed into the through groove 8, the first arc clamp 4 and the second arc clamp 5 are disassembled, so that the clamping rod 6 is moved out of the solder tail 2, and the shell 1 and the solder tail 2 can be disassembled, which is convenient for maintenance of the internal pins 3 and cables. During use of the cable connector, the heat absorbing rod 19 absorbs the heat generated in the shell 1 and conducts the heat to the heat conducting plate 18 through the heat dissipation channel 20. The external heat conducting plate 18 dissipates the heat, thereby cooling and dissipating the heat in the cable connector.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
