Recently, a large number of electronic components or sensors have been used for automotive electronics. Electrical signals are generated simultaneously by multiple electronic components or sensors. The signals generated in this way are transmitted to a control device or a driving device through a plurality of signal lines. In this process, electromagnetic waves generated by electrical signals may be irregularly generated. When the electromagnetic wave is transmitted directly or indirectly to the signal line or the electronic device, the electronic device may be abnormally operated and the driver may be in a dangerous situation.

In order to prevent this, a shield cable is generally used for a harness of an automobile, and the shield cable is a center line made of a conductor, an inner shell surrounding the center line, a shield layer formed by wrapping a braided line outside the inner shell, and an outer portion of the shield layer.

Here, the shield layer made of a conductive material is prevented from absorbing noise generated from the outside and penetrating to the center line for transmitting a signal.

In addition, when the shielded cable is connected to an electric device or a cable of a different type by using a connector having no separate shielding member, noise generated from the outside may affect the connection point. Therefore, in order to connect the shielded cable with an electric device or a cable of a different type, it is necessary to use a shield connector having a structure that can prevent noise from outside from penetrating into the connection point.
