Electrical connector for flat conductor

1. An electrical connector for a flat conductor, said connector comprising a housing formed with a receptacle into which a connecting portion provided on a front end side of the flat conductor is inserted forward, a plurality of terminals made of sheet metal and arranged on and supported by the housing at a right angle to an upper wall and a bottom wall of the housing, and a pressurizing member disposed on an opposite end of the front end side of the flat conductor that is movably supported by the housing and that increases the contact pressure between the flat conductor and the terminals;

the housing comprising the upper wall and the bottom wall that protrudes rearward with respect to the upper wall, and the receptacle is open rearward and upward at a rear portion of the housing;

a fixing groove formed at a rear end of the bottom wall that protrudes rearward, the fixing groove formed towards the rear portion of the housing that is open rearward and upward;

wherein at least some of the plurality of terminals each have a lower arm that is supported by the bottom wall of the housing and is formed with a lower striking portion that strikes the lower face of the flat conductor, and an upper arm that is linked via a linking portion to the lower arm, receives force from the pressurizing member, presses on the upper face of the flat conductor, and is formed with an upper striking portion that increases the contact pressure between the flat conductor and the lower striking portion, the upper striking portion positioned below the upper wall;

the lower arm comprising at least one lower flexible arm that is elastically displaceable and wherein at least one of the at least one lower flexible arm extends forward from the fixing groove and forward from the rear portion of the housing that is open rearward and upward to position the lower striking portion below the upper wall; and

the upper arm comprising at least one upper flexible arm that is elastically displaceable.

2. The electrical connector for a flat conductor according to claim 1 , wherein the at least one lower flexible arm comprises at least a first lower flexible arm and a second lower flexible arm that are elastically displaceable independently of each other,

the lower striking portions each have a first lower striking portion formed on the first lower flexible arm and a second lower striking portion that is formed on the second lower flexible arm at a position that is offset in the longitudinal direction with respect to the first lower striking portion,

wherein the at least one upper flexible arm comprises at least a first upper flexible arm and a second upper flexible arm that are elastically displaceable independently of each other, and

the upper striking portions each have a first upper striking portion formed on the first upper flexible arm and a second upper striking portion that is formed on the second upper flexible arm at a position that is offset in the longitudinal direction with respect to the first upper striking portion.

3. The electrical connector for a flat conductor according to claim 2 , wherein the lower striking portions are provided at positions where the first lower striking portions are opposite the first upper striking portions of the upper striking portions in the up and down direction, and the second lower striking portions are opposite the second upper striking portions in the up and down direction.

4. The electrical connector for a flat conductor according to claim 2 , wherein the lower flexible arms and/or the upper flexible arms of the terminals are in a two-ply structure obtained by bending a single sheet of metal.

5. The electrical connector for a flat conductor according to claim 3 , wherein the lower flexible arms and/or the upper flexible arms of the terminals are in a two-ply structure obtained by bending a single sheet of metal.
