Embodiment Construction

[0028] Refer below Figure 1 to Figure 6 Each embodiment of the present invention will be described.

[0029] (Embodiment 1)

[0030] figure 1 and figure 2 An electrical connector according to Embodiment 1 of the present invention is shown.

[0031] figure 1 main view, figure 2 for along figure 1 Sectional view of line A-A.

[0032] The present electrical connector is composed of an insulating case 1 molded from resin into a rectangular parallelepiped block elongated in the width direction, and a plurality of terminals 10 respectively attached to the case 1 by fixing portions 5 . The terminal 10 has a joint portion 13, and is joined to a circuit board (not shown) by lead-free soldering or the like.

[0033] The casing 1 is formed by molding an insulating resin into a box shape, and an internal cavity 18 is formed on the upper surface by a partition wall 9 that connects an opening 16 serving as a connection hole and a wall 17 extending inwardly from the partition w...

Abstract

The objective is to provide an electric connector free from short-circuit between adjacent electrodes even a whisker is grown by the stress added at all time when holding FFC or FPC on which, lead-free plating is applied. Insulation parts 11 of an FFC, FPC base 3 and an extension separating walls 6 are made to closely contact with each other, and contacts 8 of respective terminals are constructedso as to exist in a space of which, all quarters are closed, by forming an extension separating wall 6, extending in such a direction that the separation wall 9 located between terminals 10 get near to a wall part 17 of a housing 1, so as to become slightly narrower than the thickness of an FFC, FPC base 3. By the above, a whisker 15 growing from the contact 8 is prevented from reaching adjacent contact beam 2 or the contact 8 by the extension separating wall 6, and the short-circuit is prevented.

Description

technical field [0001] The present invention relates to an electrical connector for a flexible flat cable (hereinafter referred to as FFC) or a flexible printed circuit board (hereinafter referred to as FPC). Background technique [0002] Figure 7 In order to show the front view of the traditional connector inserted with FFC or FPC state, Figure 8 for along Figure 7 Cutaway view of C-C. [0003] This conventional electrical connector has a housing 1 and a contact post (Contaketobiimu) 2 of a terminal fixedly supported in a terminal installation space formed from the connecting surface toward the inside of the housing, and the housing 1 is provided with The separation wall 9 does not intersect or contact with the aforementioned contact column 2 . 5 is a fixing part of a terminal. [0004] The height dimension of this separation wall 9 is set to ensure a gap larger than the thickness of the substrate 3 of FFC and FPC between the wall portion 17 of the terminal installati...
