Right-angle electrical connector

1. A right-angle electrical connector comprising:

a guiding portion configured to insert and extract a counterpart connector formed in a front portion of a housing holding blades that retain multiple electroconductive elongated members in place in array form by insulating plates, and has a mounting surface for mounting to a circuit board on a bottom face of the housing making an angle to a front face of said housing, and in which the electroconductive elongated members retained in place by the insulating plates have arm portions extending in a rectilinear configuration in a forward-backward direction along a direction of connector insertion and extraction, and

leg portions coupled to the rear ends of said arm portions via bend portions and extending downwardly toward the bottom portion, the arm portions comprising contact portions configured to corresponding terminals in a counterpart connector formed in the front end portions thereof,

wherein the leg portions have connecting portions solder-connected to corresponding circuits on a circuit board formed at the lower ends thereof, wherein the blades are formed such that the portions of the electroconductive elongated members are retained in place by the insulating plates, the housing has formed therein holding portions allowing for the blades to be inserted from the rear, said holding portions have formed therein guiding portions guiding the insertion of the blades from the rear by guiding grooves extending in the forward-backward direction, and movement of the blades in an up-down direction within the guiding grooves is restricted;

wherein there is provided multiple types of the blades and, in said multiple types of blades, the arm portions and the leg portions of the electroconductive elongated members of the multiple types of blades are set to different lengths such that the arm portions of the electroconductive elongated members are positioned successively so as to be spaced apart from one another in an up-down direction and the leg portions of the electroconductive elongated members are positioned similarly in the forward-backward direction.

2. The right-angle electrical connector according to claim 1 , wherein the guiding portions are formed at both ends of the holding portions in the array direction of the electroconductive elongated members, and movement of the blades in the above-mentioned array direction within the guiding grooves of said guiding portions is restricted.

3. The right-angle electrical connector according to claim 1 , wherein a plurality of the holding portions are formed in alignment with the multiple types of blades.

4. The right-angle electrical connector according to claim 1 wherein the blades have formed therein protrusions projecting from the major faces of the insulating plates and the amount of insertion of the from the rear into the above-mentioned holding portions is restricted by said protrusions.

5. The right-angle electrical connector according to claim 1 , wherein the holding portions have formed therein stopper portions used to restrict the amount of insertion of the blades from the rear at locations different from the guiding portions in the array direction, and the above-mentioned protrusions are abuttable against the rear faces of said stopper portions at locations corresponding to the stopper portions in the above-mentioned array direction.

6. The right-angle electrical connector according to claim 5 , wherein the stopper portions are formed protruding from the interior wall surface of the holding portions.

7. The right-angle electrical connector according to claim 4 , wherein the protrusions of the blades are abuttable against the rear faces of the guiding portions at locations corresponding to said guiding portions in the array direction.
