Electrical connector with regulation means

1. An electrical connector comprising:

a first connector having a plurality of substantially L-shaped first contact elements;

a second connector having a plurality of second contact elements that are brought into contact with said first contact elements when said first and second connectors are plugged to each other in a plugging direction;

at least one arranging section provided on said first connector and extending in both said plugging direction and a longitudinal direction that is perpendicular to said plugging direction so as to support said first contact elements thereon;

at least one fitting cavity provided on said second connector and extending backwardly in said plugging direction and in said longitudinal direction so as to support said second contact elements on a wall thereof at positions corresponding to those of said first contact elements;

a plurality of first projections and recesses provided along on a first longitudinal side wall and an second longitudinal side wall opposite to the first longitudinal side wall of said arranging section in said longitudinal direction, with each of said first contact elements being disposed adjacent to or in contact with a side wall of each of said first projections to form a larger projection; and

a plurality of second projections and recesses provided on said wall of said fitting cavity so as to mesh with said first projections and recesses, with said first contact elements being held between said first and second projections within said second recesses, when said first and second connectors are plugged to each other.

2. The electrical connector according to claim 1 , wherein said first contact elements are provided adjacent to or in contact with said arranging section at a side thereof and said second contact elements are provided adjacent to or in contact with said wall of said fitting cavity at a side thereof.

3. The electrical connector according to claim 1 , wherein said first contact elements are provided adjacent to or in contact with said arranging section on opposite sides thereof and said second contact elements are provided in said fitting cavity on opposite sides thereof.

4. The electrical connector according to claim 1 , which further comprises at least one first slope provided on said arranging section for guiding said second connector and at least one second slope provided on a wall of said fitting cavity for guiding said first connector.

5. A first connector to be plugged to a second connector in a plugging direction, comprising:

at least one arranging section extending in both said plugging direction and a longitudinal direction that is perpendicular to said plugging direction;

a plurality of substantially L-shaped first contact elements provided on said arranging section and brought into contact with a plurality of second contact elements provided on a wall of a fitting cavity in said second connector when said first and second connectors are plugged to each other; and

a plurality of first projections and recesses provided along on a first longitudinal side wall and an second longitudinal side wall opposite to the first longitudinal side wall of said arranging section in said longitudinal direction, with each of said first contact elements being disposed in each of said recesses adjacent to or in contact with a side wall of each of said projections to form a larger projection to mesh with a plurality of second projections and recesses provided on said wall of said fitting cavity so that said first contact elements are held between said first and second projections within said second recesses when said first and second connectors are plugged to each other.

6. The first connector according to claim 5 , wherein said first contact elements are provided adjacent to or in contact with said projects at a side thereof.
