Problems solved by technology
[0003] The jumper connection method is simple and clear, the volume is small, and it is easy to change the wiring mode. However, the MVB electrical connector using the jumper connection method is close to irreversible. After the jumper is cut, it needs to be restored. Welding; and the cut jumper wires are easy to fall between the printed board assembly and the shell, which is difficult to remove and is more likely to be ignored, causing a short circuit; when the jumper wires are cut, the splashed jumper wires are also likely to hurt human eyes

Embodiment Construction
[0018] The present invention will be further elaborated below in conjunction with the accompanying drawings.
[0019] Such as figure 1 , figure 2 As shown, an embodiment of the present invention can repeatedly switch the MVB electrical connector of the wiring mode, which includes a housing assembly 1, such as figure 1 As shown, the appearance component 1 of the MVB electrical connector in this embodiment can repeatedly switch the wiring mode, and the appearance of the appearance component can be perceived intuitively and beautifully.
[0020] The specific internal structure is as figure 2 As shown, the shell assembly 1 is provided with a printed board assembly 2; a dial switch 3 is arranged on the printed board assembly; in this embodiment, the dial switch can have many models to choose from, and there are in-line type according to the pin position. (DIP) and SMD (SMD) are optional. According to the way of dialing, there are flat dial type and side dial type. According to...

The invention discloses an MVB electric connector with wiring modes capable of being switched repeatedly. The MVB electric connector comprises a shell assembly. A printed board assembly is arranged in the shell assembly. A dial switch is arranged on the printed board assembly. A circuit system is arranged on the printed board assembly. The circuit system controls switch-on and switch-off of the circuit system through switch-off and switch-on of the dial switch, so that switching of the wiring modes of the electric connector is achieved. According to the MVB electric connector, the wiring mode is changed from a traditional jumper wire connection mode to the connection mode of the dial switch with the wiring modes capable of being switched repeatedly; the MVB electric connector achieves switching of the wiring modes by controlling switch-off and switch-on of the switch. According to the scheme, the MVB electric connector with the wiring modes capable of being switched repeatedly solves the problem that an existing electric connector is unrecoverable after being dismounted through the traditional wiring mode and avoids short circuits, product insulation, degradation of withstand voltage performance and other faults caused in the dismounting process; moreover, since the novel wiring mode is adopted, the whole circuit connection makes appearance be more attractive, and operation is easier; the dismounting operation is omitted, the production efficiency is improved, and the MVB electric connector conforms to the environmental protection concept.
Description
technical field [0001] The invention relates to the field of electrical connectors, in particular to rail transit, communication electrical connectors inside and between vehicles, and in particular to an MVB electrical connector capable of repeatedly switching wiring modes. Background technique [0002] Multifunctional Vehicle Bus (MVB) is a serial data communication bus mainly used (but not exclusively) for interconnected devices requiring interoperability and interchangeability. Multifunction Vehicle Bus (Multifunction Vehicle Bus), which is a part of the train communication network TCN, and the TCN network is composed of MVB+WTB. MVB type electrical connectors are widely used in the communication circuits of rail transit, but due to the many wiring methods of the same electrical connector and the strict volume requirements, multiple jumper wires are usually set on the printed board to realize the function. convert. [0003] The jumper connection method is simple and cle...
