Problems solved by technology

However, since the contact portions 64, 65 are relatively large and have circular arcs, when an unexpected pull-out force acts on the flat circuit board F, it is easy to fall off sometimes.

Embodiment Construction

[0030] Based on the following Figure 1 to Figure 5 Examples of the present invention will be described.

[0031] exist figure 1 In the shown embodiment, the cross-section of the housing 1 made of electrical insulating material is horizontally long and extends in a direction perpendicular to the paper, and its overall shape is roughly cuboid. In addition, the terminal 10 held by this case 1 is obtained by performing press work of a metal plate, for example.

[0032] The above housing 1 such as figure 1 As shown, there is an upper wall 2 and a lower wall 3, and the upper wall 2 and the lower wall 3 are connected by side walls on the near side and the far side of the paper, with left and right openings. On the left side, a first opening 4 into which a flat type circuit board is inserted is formed, and on the right side, a second opening 5 into which a terminal 10 is inserted and a pressing member 20 moves is formed. The second opening 5 also opens upward on the right end s...

Abstract

The invention provides an electric connector for a flat circuit board capable of obtaining terminals (10) by working a metal plate while maintaining the plate surface of the metal plate. The plurality of terminals are held by a housing (1) at intervals in the direction right-angled to the plate surface. The terminals (10) include protrusions (11A, 12A) formed at opposed edges of two substantially parallel arm bodies (11, 12). A flat circuit board (F) is nipped between the protrusions by elastically narrowing the distance between the protrusions of the two arm bodies by application of an external force to the terminal, whereby the flat circuit board is connected to the terminals (10). The invention is characterized in that the protrusion (12A) of at least one arm body includes a sharpened part, the sharpened part is respectively formed at the front edge and the rear edge in front and at the rear of an insertion direction of the flat circuit board, the surface of the flat circuit board at the rear edge makes an acute angle with the front edge. The electric connector for the flat circuit board of the invention can surely prevent accidental separation of the flat circuit board.

Description

technical field [0001] The present invention relates to an electrical connector for a flat circuit board. Background technique [0002] As flat circuit boards, flexible printed circuit boards (FPC), flat cables, and the like are known. As an electrical connector for connecting this flat circuit board to a member to be connected, for example, another circuit board, for example, a connector disclosed in Patent Document 1 is known. [0003] The connector of this patent document 1, such as Figure 6 As shown, the terminal 60 held by the housing 50 is given a shape by performing stamping and other processing on a metal plate while maintaining its plate surface, and has two parallel arms 61 and 62, and these arms are in the middle position The connected portion 63 is integrally connected. The two wrists 61, 62 have protruding contact portions 64, 65 on one end side. The protruding contact portions 64, 65 have circular arcs facing each other. The connecting portion 66 that protr...
