And a mounting end 921c installed so as to be mounted. The terminal module 92 and the shield housing 94 are insulated by bending the contact part 921b with respect to the fastening part 921a and forming a bent part 921d protruding outside the front end face of the insulating block 920 between the two. After being attached to the main body 90, only the air layer is used as an electrical insulating layer between the bent portion 921d of the conductive terminal 921 and the top wall 940 of the shield housing 94.

[0003]

[Problems to be solved by the invention]

 However, when the usage environment of the electrical connector changes (for example, when lightning strikes), when a high potential difference is generated between the shield housing 94 and the conductive terminal 921, the distance between the bent portion 921d and the top wall 940 of the shield housing 94 decreases. Since it is small, the electrical insulation impedance of the air layer makes it difficult to prevent a large current (high piezoelectric arc) from being generated between the bent portion 921 d of the conductive terminal 921 and the shield housing 94, and also damages the connector 9. Therefore, it is necessary to enhance the high-voltage breakdown prevention function of the conventional connector.
