Connector assembly for connection under voltage
First Claim
1. A connector assembly for connection under voltage, comprising:
- a first connection element provided with at least one male contact protruding out of a connection face of said first connection element;
and a second connection element provided with at least one female contact element housed in a cavity opening out on to a connection face of said second connection element so that said male contact element can be inserted into said cavity and come into contact with the corresponding female contact, wherein;
at least one male contact element has one portion of greater diameter and one portion of smaller diameter, both protruding out of the connection face of the first connection element, the portion of greater diameter being upstream to the portion of smaller diameter,at least one female contact element has a contact piece housed at the bottom of the cavity and a local narrowing of diameter, upstream of the contact piece housed at the bottom of the cavity, said local narrowing of diameter having a size smaller than or equal to the diameter of the portion of greater diameter of the male contact element, and a size strictly greater than the diameter of the portion of smaller diameter of the male contact element,so that, during a connection between the two connection elements, the portion of greater diameter of the male contact element comes into contact with the local narrowing of diameter of the female contact element in the corresponding cavity before the portion of smaller diameter of the male contact element comes into contact with the contact piece housed at the bottom of said cavity wherein, when an electrical arc is created, the electrical arc is created in a non-functional zone of the local narrowing of diameter of the female contact element and the portion of greater diameter of the male contact element.

Abstract
A connector includes a first connection element (2) provided with a portion of greater diameter (9) upstream to a portion of smaller diameter (10) and a second connection element (3) provided with a female contact element (14, 16) including a local narrowing of diameter (20), the narrowing being upstream to a contact piece (14) housed at the bottom of a cavity. During the connection between the two connection elements, the portion of greater diameter of the male contact element comes into contact with the local narrowing of diameter of the female contact element in the corresponding cavity, before the portion of smaller diameter of the male contact element comes into contact with the contact piece housed at the bottom of the cavity.
