Electrical connector having a centering member

A connector system having a first substrate in which at least one perpendicularly projecting guide pin is attached on which a coding key is mounted, and having a second substrate having a coding box arranged thereon for receiving the guide pin during the mating operation, the coding box having a complementary coding key inserted therein from a mating end and an electrical spring contact being formed on the coding box rearward of the complementary coding key, said electrical spring contact clampingly retaining the inserted guide pin in the coding box, the connector system comprising a centering member for pre-aligning the guide pin during insertion, the centering member being positioned inside the coding box between the complementary coding key and the spring contact so that the guide pin is received in the centering member before the coding key cooperates with the complementary coding key.

An electrical connector system for forming an electrical connection between a pair of substrates comprising:

• a guide pin fastened to the first substrate, the guide pin having a pre-engagement guide section and a fastening section, the fastening section having a fastening zone and a guide zone, said fastening zone having a predetermined diameter and configured as a sturdy press fit zone to be mounted in a mounting hole of the first substrate;
• a female connector fixed to the second substrate having a coding box, the coding box having a contact disposed at a rear end thereof, a coding key disposed within the coding box at a mating end thereof, and a centering member disposed inside the coding box between the contact and the coding key, the centering member positioned to receive the guide pin and pre-align the guide pin before the guide pin engages the contact to prevent stubbing of the contact.
