[0002] Connectors are also often called circuit coaxial connectors, electrical connectors, and conductor devices that bridge two conductors on a loop so that current or signals can flow from one conductor to another. Connectors are motor systems that can provide a separable interface for connecting two sub-electronic systems. Simply put, the components used to complete the electrical connection between circuits or electronic machines become connectors, which are bridges between the two. Coaxial connectors refer to the parts used to connect the ends of two shafts to ensure that the center lines of the two shafts are on the same axis.

As shown in the figure, the present invention discloses a coaxial connector 1, which includes an outer shell 10, an inner shell 11, an outer core 12, an inner core 13, a pressure ring 14, a plurality of PIN pins 15 and a plurality of connectors 16. The outer shell 10 has a first accommodating space 100 and a second accommodating space 101 that are connected to each other. The inner diameter of the second accommodating space 101 is larger than that of the first accommodating space 100. Thus, a platform 103 is provided at the connection between the first accommodating space 100 and the second accommodating space 101. The inner shell 11 is built into the first accommodating space 100, and the inner shell 11 has an installation space 110. The outer core 12 is disposed in the installation space 110, one end of the outer core 12 abuts against the platform 103, and the outer core 12 has a plurality of PIN pin installation holes 120. The inner core 13 is built into the second accommodating space 101, and the inner core 13 has a plurality of connector installation holes 130 corresponding to the plurality of PIN pin installation holes 120. The pressing ring 14 is disposed in the first accommodating space 100, and the pressing ring 14 abuts against the outer core 12. The pressing ring 14 fixes the outer core 12 to prevent the outer core 12 from being separated from the installation space 110, causing the coaxial connector 1 to be powered off or damaged. In addition, the use of the pressing ring 14 to fix the outer core 12 reduces the use of fixing screws or fixing glue, making the coaxial connector 1 easy to disassemble and assemble, and not easy to cause the internal parts of the coaxial connector 1 to loosen, thereby extending the service life of the coaxial connector 1 and reducing the production cost of the coaxial connector 1. One end of a plurality of PIN pins 15 is fixed to a plurality of PIN pin mounting holes 120; a plurality of connectors 16 are fixed to a plurality of connector mounting holes 130, and a plurality of connectors 16 are connected to one end of a plurality of PIN pins 15 via cables.

The fixing plate 104 has four screw holes 105. After the coaxial connector 1 is connected, four screws are used to pass through the four screw holes 105 to fix the coaxial connector 1, which is simple and fast, easy to disassemble and assemble, and not easy to cause the internal parts of the coaxial connector 1 to loosen, thereby extending the service life of the coaxial connector 1.

[0037] In order to prevent the outer core 12 from rotating, the outer core 12 is fixed to the installation space 110. Figure 6 The side wall of the inner shell 11 has a first clamping block 111, and the outer core 12 has an outer core clamping groove 121 corresponding to the first clamping block 111. When the outer core 12 is arranged in the installation space 110, the first clamping block 111 is clamped with the outer core clamping groove 121, which reduces the use of fixing screws or fixing glue, makes the coaxial connector 1 easy to disassemble and assemble, and is not easy to cause the internal parts of the coaxial connector 1 to loosen, thereby extending the service life of the coaxial connector 1 and reducing the production cost of the coaxial connector 1.

[0038] In order to fix the coaxial connector 1 and prevent the coaxial connector 1 from loosening, refer to Figure 3 and Figure 4 The housing 10 of the present invention has four fixing screws 106, and the four fixing screws 106 surround the second accommodation space 101 in a circumferential manner, and the four fixing screws 106 correspond to the inner core 13. When the coaxial connector 1 is in use, another coaxial connector is connected to the coaxial connector 1 of the present invention, and the other coaxial connector is fixed by the four fixing screws 106. The fixing of the coaxial connector 1 is simple and fast, and the disassembly and assembly are convenient. It is not easy to cause the internal parts of the coaxial connector 1 to loosen, and the service life of the coaxial connector 1 is extended.
