Problems solved by technology

[0008] In addition, since the base 42 is provided with the receiving hole 42a through which the contact portion 43 passes, it is impossible to make the width of the base 42 and the groove 33 small so that the connector cannot be made into a desired smaller size.

Embodiment Construction

[0039] Refer to the following Figures 4A to 8A , to further describe the electrical connector of the preferred embodiment of the present invention. Such as Figures 4A to 5 As shown, the connector 1 includes a plurality of contact pieces 2 arranged oppositely in two rows and an insulator 3 accommodating the contact pieces 2 .

[0040] Such as Figure 6 As shown, each contact member 2 includes a base 21, a contact portion 22, a U-shaped protruding portion 2a protruding obliquely upward at the free end of the contact portion, and a generally U-shaped elastic portion 2b, which connects the base 21 One end and the opposite end of the contact portion 22.

[0041] In detail, the shape of the contact portion 22 is bent upwardly at the bent portion 22a to form an inclined portion, which is bent into a U shape to form an inclined U-shaped protruding portion 2a.

[0042] The base portion 21 is provided adjacent to its opposite ends as press-fit portions 2c with two laterally projec...

Abstract

In an electrical connector having at least one contact (2) held in at least one contact accommodating groove (3a) formed in an insulator (3), the contact (2) comprises a base portion (21) press-fitted in the contact accommodating groove (3a), a contact portion (22) projecting (2a) from the contact accommodating groove (3a) upward, and a U-shape spring portion (2b) connecting the base portion (21) and the contact portion (22). The contact accommodating groove (3a) comprises a relatively large width section (3a-1) adjacent to the end wall (3e) and a relatively small width section (3a-2) adjacent to the open end. Opposite side walls at the relatively small width section (3a-2) are formed with press-fit grooves (3d) adjacent to the bottom wall (3c). The base portion (21) of the contact (2) is formed with lateral projections (2c) laterally projecting from the opposite sides of the base portion (21), and the lateral projections (2c) are press-fit in the press-fit grooves (3d) respectively. The base portion (21) of the contact (2) has a slender part which extends between the U-shape spring portion (2b) and the lateral projections (2c) and which is smaller in width than the width of the relatively small width section (3a-2) of the contact accommodating groove (3a).

Description

technical field [0001] The present invention relates to electrical connectors for connecting a printed circuit board to another printed circuit board, flex printed circuits, liquid crystal displays and the like. Background technique [0002] refer to figure 1 , 2 and 3, general electrical connectors will be described. Such a conventional electrical connector is described in Japanese Unexamined Patent Publication (JP-A) No. 102758 (1999). [0003] The connector main body 31 is generally a rectangular parallel tubular insulator molded by resin. The main body 31 has a plurality of slots 33 parallel to each other. Thus, each groove is defined by a bottom wall 32, an upper wall 35 facing the bottom wall 32 and opposite side walls. The upper wall 35 is provided with a plurality of openings 34 . The bottom wall 32 defines an accommodating space 36 connected to the groove 33 . Press-fit grooves 37 are respectively provided on the side wall along both sides of the groove 33 . ...
