Abstract: A communication device includes a case, a cover, a signal processing module and a signal switching module. The cover whereon the signal processing module is disposed is detachably assembled with the case. The signal switching module is disposed on the case and includes a connection component and a conductive component. The connection element includes a switching element, a chamber, a device port and a module port. The device port is connected to external devices. The switching element is movably disposed inside the chamber. The conductive component is located inside the case, and is spaced from the device port by the switching element when a signal transmission terminal of the signal processing module is inserted into the module port, and further contacts against the device port when the signal transmission terminal is removed from the module port, so as to maintain signal transmission between external devices.

Abstract: A coaxial cable connector includes a metal sleeve, a metal clamping sleeve, a coupling sleeve and an elastic ring. The metal sleeve jackets an insulation layer of a coaxial cable and is coupled to a metal fence layer of the coaxial cable when the coaxial cable connector jackets the coaxial cable. The metal clamping sleeve jackets a first end portion of the metal sleeve for tightly clamping the coaxial cable. The coupling sleeve is detachably connected to a device connector and rotatably jackets a second end portion of the metal sleeve. The elastic ring is disposed in the coupling sleeve and fixedly jackets the second end portion. The elastic ring has a thick portion at least partially protruding from the second end portion relative to the metal sleeve and an abutting structure extending toward the first end portion axially for pushing the coupling sleeve against the metal clamping sleeve tightly.
