Abstract

The invention provides a DB9 type bus joint. The DB9 type bus joint comprises a shell, a circuit board and a plug, a containing cavity is formed in the shell, the circuit board is transversely installed in the containing cavity, and the distance between the circuit board and the inner bottom wall of the containing cavity is equal to the distance between the circuit board and the inner top wall ofthe containing cavity; and the plug is arranged on the shell, and one end of the plug is electrically connected with the circuit board. According to the DB9 type bus joint provided by the invention, by using the novel wiring terminal and redesigning the structure of the circuit board, the wiring terminal is prevented from being contacted with the inner wall of the joint shell, and the safety performance of the DB9 type bus joint is improved.

Description

technical field [0001] The invention relates to the joint field, in particular to a DB9 type bus joint. Background technique [0002] The DB9 connector of the train bus is an indispensable device in the train network system. It is used as the terminal of the train bus cable to realize the connection between various equipment and cables. Its stability and reliability are related to the performance of the entire train network system, and play a decisive role in the safe operation of trains. [0003] At present, in the internal structure of the existing DB9 type bus connector, the circuit board is installed on one side close to the DB9 plug shell, and the circuit board is fixed by self-made retaining rings and screws. [0004] However, the circuit board inside the existing plug uses high-height terminals and switches, so that all devices can only be placed on the same side of the circuit board, and the circuit board must be placed close to the side of the plug shell. Reliabil...
