Abstract

An electric connector (6) to be attached to a plate-like connection member (4; 100) having an edge portion (402; 102), a plurality of insertion convex portions (12; 103) formed sideways at the edge portion (402; 102), and a conductive portion (8; 8B; 103a, 103b) formed on at least one of the front surface (4a; 103a). The back surface (4b; 103b) of each insertion convex portion (12; 103) includes an insulating housing (13) and a contact forming member (14; 14A; 14B; 14B'; 14C; 14C'; 14D; 14E; 14F; 14G; 14H; 14J) made of a metal and held in the housing (13). The contact forming member (14; 14A; 14B; 14B'; 14C; 14C'; 14D; 14E; 14F; 14G; 14H; 14J) includes a box-like portion (33; 33D) having four.walls (41, 42, 43, 44; 41D, 42D, 43D, 44D) and a connection member connecting contact (34; 34B) extended from at least one of the walls of the box-like portion (33; 33D). The four walls (41, 42, 43, 44; 41D, 42D, 43D, 44D) define an insertion concave portion (45) into which the insertion convex portion (12; 103) corresponding thereto is inserted along a predetermined insertion direction (P1). The connection member connecting contact (34; 34B) includes a contact portion (475; 475A; 475B; 475C; 475D; 475E; 475F; 475G; 475J) that makes contact with the conductive portion (8; 8B; 103a, 103b) of the corresponding insertion convex portion (12; 103) inserted into the insertion concave portion (45).

Description

technical field [0001] The present invention relates to an electrical connector and a connection structure of the electrical connector. Background technique [0002] Generally, an electrical connector has a synthetic resin housing and metal contacts held in the housing (see, for example, Document 1 below). [0003] Document 1: JP-A-2000-331732 (published date: November 30, 2000). [0004] The contact has a base portion fixed to the housing, an elongated bent portion extending in an S-shape from the base portion, and a protruding contact portion provided at a tip of the bent portion. The contact portion contacts and presses a conductor pattern formed on the surface of the circuit board. Accordingly, the bent portion elastically deforms, and an elastic repulsive force is applied to the conductor pattern from the bent portion. According to this, a contact pressure is generated between the contact portion and the conductor pattern. [0005] A receiving portion facing the con...
