An electrical connector system for electrically and mechanically connecting with a component in a motor vehicle is disclosed. The connector system includes a motor vehicle component and a male connector assembly with a male housing that receives a male terminal. This terminal includes a receiver and side walls with a contact arm that extends across an aperture in the side wall. An internal spring member with at least one spring arm resides within the male terminal receiver. A female connector assembly includes a female terminal with a receptacle that receives both the male terminal and the spring member. A female housing receives the female terminal and an extent of the male connector assembly. When the connector system moves from the partially assembled state to a connected position for connection of the vehicle component, the male connector assembly is inserted into female housing, the contact arm is brought into sliding engagement with an angled internal segment of the female housing, and the contact arm is inwardly displaced as the contact arm slidingly engages with the angled internal segment.

A first hold-down includes a hold-down elastic piece supported like a cantilever beam by a reinforcing plate part. The hold-down elastic piece includes an elastic piece body extending from the reinforcing plate part, and a curve contact part formed at an end of the elastic piece body and projecting toward a CPU board beyond a CPU board opposed surface. A housing is formed in such a way that the curve contact part does not come into contact with the housing when the curve contact part no longer projects toward the CPU board beyond the CPU board opposed surface as a result of the curve contact part being elastically displaced toward an input-output board.

A spring connector includes: an insulating housing having a through hole; a conductor disposed on one end side of the through hole; and a conductive external contact pin disposed on another end side of the through hole. The housing has an opening portion on the other end side of the through hole. A part of the through hole and a part of the conductor form an internal space. The external contact pin includes a tip end portion configured to protrude from the opening portion and a main body portion positioned in the through hole. The external contact pin and the conductor are configured to be switched between a non-conductive state and a conductive state by moving the tip end portion of the external contact pin in a backward direction opposite to a protruding direction in which the tip end portion protrudes from the opening portion.

An electrical element holder includes a printed circuit board having a receiver. A resilient holder is electrically engaged with the receiver. The resilient holder includes a holding portion that is defined within an outward surface of the resilient holder and between opposing resilient arms. An electrical element is secured within the holding portion between the opposing resilient arms.

An electrically conductive contact element for an electrical connector comprises a body and a layer of electrically conductive material provided on the body. The body includes a first face having at least one depression forming a reservoir defined therein. The layer of electrically conductive material is provided on the first face of the body and fills the at least one depression. The layer defines a contact surface adapted to be brought into contact with a surface of a connecting part of a mating electrical connector mated with the electrical connector. The contact surface is formed by a surface of the layer of electrically conductive material facing away from the body.
