Abstract

In an electrical connector to be connected to a mating connector in a predetermined direction, an insulator defines an accommodating space and an opening communicating the accommodating space in the predetermined direction. A contact as a base portion held by the insulator and a spring portion connected to the base portion. The spring portion has a first portion extending from the base portion in the accommodating space to intersect with the predetermined direction, a second portion turned opposite to the opening from the first portion and extending in the accommodating space to intersect with the predetermined direction, and a third portion extending from the second portion to pass through the opening. The third portion has a contact portion located outside the accommodating space to be elastically contacted with the mating connector.

Claims

1. An electrical connector to be connected to a mating connector in a predetermined direction, wherein said electrical connector comprises a conductive contact and an insulator holding said contact, wherein said insulator defines an accommodating space and an opening communicating with said accommodating space in said predetermined direction, and wherein said contact includes a base portion held by said insulator and a spring portion connected to said base portion, said spring portion comprising:

a first portion extending from said base portion in said accommodating space along a direction intersecting with said predetermined direction;

a second portion which extends from said first portion away from said opening and extends in said accommodating space along a direction intersecting with said predetermined direction, and which comprises an extended end that is a free end; and

a third portion which extends from said second portion to pass through said opening, and which comprises a contact portion located outside said accommodating space to be elastically contacted with said mating connector.

2. The connector according to claim 1, wherein said second portion comprises a U-shaped portion connected to said first portion.

3. The connector according to claim 1, wherein said extended end is in contact with said insulator.

4. The connector according to claim 1, wherein a combination of said first and said second portions serves as a first spring portion, said insulator comprises a wall part defining said opening, and said third portion comprises:

a connecting part connected to said second portion and extending in parallel to said second portion in a first direction substantially perpendicular to said predetermined direction;

an intermediate part extending from said connecting part towards said wall part in a direction intersecting with both said predetermined direction and a third direction which is perpendicular to said predetermined direction and said first direction; and

an extending part extending from said intermediate part to pass through said opening, said contact portion being formed on said extending part;

wherein a combination of said connecting part, said intermediate part, and said extending part serves as a second spring portion.

5. The connector according to claim 4, wherein said intermediate and said extending parts make an angle with respect to each other.

6. An electrical connector to be connected to a mating connector in a predetermined direction, wherein said electrical connector comprises a conductive contact and an insulator holding said contact, wherein said insulator defines an accommodating space and an opening communicating with said accommodating space in said predetermined direction, and wherein said contact includes a base portion held by said insulator and a spring portion connected to said base portion, said spring portion comprising:

a first portion extending from said base portion in said accommodating space along a direction intersecting with said predetermined direction;

a second portion which extends from said first portion away from said opening and extends in said accommodating space along a direction intersecting with said predetermined direction, and which comprises an extended end that is a free end; and

a third portion which extends from said second portion to pass through said opening, and which comprises a contact portion located outside said accommodating space to be elastically contacted with said mating connector;

wherein said first portion comprises a pair of spring plates spaced from each other and extending to intersect with said predetermined direction, and said third portion passes between said spring plates.

7. The connector according to claim 6, wherein said second portion comprises a pair of spring plates spaced from each other and respectively connected to said spring plates of said first portion, and said third portion comprises a connecting part which is placed between said spring plates of said second portion and connected to said spring plates of said second portion.

8. The connector according to claim 6, wherein said third portion comprises an extending part facing a space between said spring plates of said first portion, and said contact portion is formed on said extending part.
