The invention discloses a communication module based on an ejector pin communication mode, which comprises a module body and a communication guide rail. The module body comprises a housing base and acircuit board module; an accommodating cavity for accommodating the circuit board module is formed in the housing base; a shell cover is mounted on the housing base; ejector pins re arranged at the bottom of the housing base; the circuit board module is connected with the ejector pins; and a first connection portion and a second connection portion are arranged at the edge of the housing base. According to the invention, communication between the modules is carried out by utilizing the ejector pins of the module body and the communication guide rail, cost of wires is greatly reduced, the problem of connection fault of signal lines does not need to be worried about, a fault rate is effectively reduced, and the communication module is safe and reliable. Moreover, according to the invention, when the module is installed, only the first connection portion and the second connection portion need to be buckled between the modules, so that the communication module is convenient to use and is tidy and attractive. The communication module can be widely applied to the field of the communication module.
Description
technical field [0001] The invention relates to a communication module, in particular to a communication module based on a thimble communication mode. Background technique [0002] In the use of existing modules, the communication method between modules is to connect the power cord to the socket jumper. When the number of modules that need to communicate increases, the required power cord More and more, more and more sockets are needed. On the one hand, the cost of the wire increases, and the communication signal will also be weakened. On the other hand, the installation method is untidy and unattractive, and the wiring is prone to errors. Once the wiring goes wrong, it will cause system failure. If the signal line and the power supply line are accidentally reversed, the communication port of the entire system module may be burned. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the object of the present invention is to provi...
