Description

The present invention relates to a multiplex communication connector having a noise elimination function.

2. Description of the Related Art Conventionally, a multiplex communication connector is used to connect communication lines routed to control a plurality of electrical components mounted on a vehicle by communication.
This connector for multiplex communication has ferrite as a magnetic material for removing noise inside the connector housing.

For example, in Patent Document 1, a second housing assembled to the rear of the first housing has a plurality of ferrites attached to each ferrite at positions corresponding to a plurality of connector fitting portions provided on the first housing. A multiplex connector is described which is held by a pair of biasing arms on each side.

JP 2012-69270 A

However, in the connector for multiplex communication described in Patent Document 1, the pair of biasing arms bias and hold the ferrite from both sides of the ferrite, so the size of the second housing is reduced to one pair. There is a problem that the size of the connector as a whole is increased due to the increase in size in the opposite direction of the urging arm.
Further, in the connector for multiplex communication described in Patent Document 1, the mounting position of the ferrite is displaced due to elastic deformation or dimensional crossing of the urging arm, and the terminal contacts the through-hole of the ferrite, resulting in wear of the ferrite. Therefore, there is a problem that the noise removal performance is degraded, and as a result, the communication reliability is degraded.
