  The capacitor 102 with a lead wire built in the conventional shielded connector with built-in electronic element needs to change the capacitance depending on the in-vehicle system, and has a capacitor with a different capacitance for each system. However, once a capacitor is incorporated into such a shield connector with built-in electronic elements, the capacitor cannot be seen from the outside. Therefore, if a terminal (terminal + shielded wire) is mixed due to some assembly error, There was a problem that the capacity could not be visually confirmed.

  Therefore, the problem to be solved by the present invention is to provide an electronic element built-in shield connector that can visually recognize the built-in electronic elements.

For example, if the electronic element is a capacitor, even if mixing with other connectors with different capacitances, the difference in capacitance can be confirmed in appearance, so it can be divided appropriately and workability Will improve. Moreover, the presence or absence of an electronic element can also be confirmed.

  Further, in the shielded connector with built-in electronic element, an identification display of the electronic element is provided on the outer surface of the dielectric element including the inner conductor terminal connected to the core wire of the shielded wire through the electronic element together with the electronic element. According to the shielded connector with built-in electronic element in which the first opening that makes the portion visible is formed, even in the state of the dielectric assembly in the middle of the connector assembly, for example, when the electronic element is a capacitor, Even when mixing with other dielectric assemblies having different capacities occurs, the difference in electrostatic capacity can be confirmed in appearance, so that they can be appropriately separated. Moreover, the presence or absence of an electronic element can also be confirmed.

  In this case, the identification display portion of the electronic element can be visually recognized through the first opening on the outer surface of the outer conductor terminal that is connected to the shield conductor of the shielded electric wire and encloses the dielectric. If the second opening is formed, even in the state of the outer conductor terminal assembly in the middle of the connector assembly, for example, when the electronic element is a capacitor, other outer conductor terminal assemblies with different capacitances can be used. Even if mixing occurs, since the difference in capacitance can be confirmed in appearance, it can be divided appropriately.

Further, on the outer surface of the connector housing that encloses the outer conductor terminal, a third opening that makes the identification display portion of the electronic element visible through the first opening and the second opening. If the structure is formed, even when the assembly is completed after the connector assembly is completed, for example, when the electronic element is a capacitor, even if mixing with other connector assemblies with different capacitance occurs, Since the difference in capacitance can be confirmed, it can be appropriately divided. Moreover, the presence or absence of an electronic element can also be confirmed.
