Filed:

Jan 5, 2000

Appl. No.:

09/477670

Inventors:

Ping Chen - Mundelein IL
Takashi Iida - Anjo, JP

Assignee:

Japan Solderless Terminal Mfg. Co., Ltd. - Osaka-fu

International Classification:

H01R 424

US Classification:

439422, 439877

Abstract:

An FPC crimp terminal comprising a bottom plate being formed from a flat plate and a fixing part rising from an edge of the bottom plate, said FPC crimp terminal being formed in such a way that when a core or a lead wire is brought into direct contact with a conductor of an FPC, the fixing part is made to pierce the FPC from its back or front and the top end of the fixing part coming out of the FPC is bent towards the bottom plate, the core or the lead wire and the FPC will be pinched between the top end of the fixing part and the bottom plate. As the fixing part is used to effect the piercing process and the connecting process at the same time, the FPC crimp terminal can be compactified and the work efficiency can be enhanced through reduction in the number of processes.

Appl. No.:

09/392582

Inventors:

Ping Chen - Mundelein IL

Assignee:

Japan Solderless Terminal Mfg. Co., Ltd. - Osaka

International Classification:

H01R 1122

US Classification:

439852, 439451

Abstract:

A female terminal for a connector wherein a leaf spring is provided inside the terminal proper. The front half of the terminal proper is provided with a bottom wall, side walls rising from both ends, in the direction of width, of the bottom wall, an outer upper wall and an inner upper wall extending from the upper edges of side walls to the upper edges of the opposing side walls. A leaf spring is formed by separating said rear inner upper wall from said side walls, with the rear end of said rear inner upper wall being left intact. A bead with a curved section is formed on the leaf spring to increase the flexural rigidity. The female terminal can be compactified, and a sufficient contacting force can be provided reliably. The contacting part of the leaf spring can be shifted forward. The developed shape can be made smaller.

Appl. No.:

11/634269

Inventors:

Byung Yong Kim - Hainesville IL, US
Ping Chen - West Bloomfield MI, US

Assignee:

J.S.T. Corporation - Farmington Hills MI

International Classification:

H01R 13/627

US Classification:

439352, 439353, 439357

Abstract:

A connector position assurance device includes a base panel member and a latch assembly connected to and extending generally perpendicularly from the base panel member. The latch assembly has a tongue part and a pair of rails disposed apart from and extending parallel to one another. The tongue part is positioned between and disposed apart from the pair of rails to define a pair of open-ended stop-receiving channels. The tongue part is formed with a slot and a follower projection is connected to the tongue part forward of the slot. The tongue part is movable, in an upward direction, to and between a relaxed normal position and an upward flexed position and, in a downward direction, to and between the relaxed normal position and a downward flexed position. The tongue part is resiliently biased to the relaxed normal position. A connector assembly incorporates the connector position assurance device.

Appl. No.:

9/348393

Inventors:

Ping Chen - Mundelein IL

Assignee:

Japan Solderless Terminal Mfg. Co., Ltd. - Osaka

International Classification:

H01R 1122

US Classification:

439852

Abstract:

A female terminal for a connector comprising a terminal body that is fixed by a retainer of a housing, a leaf spring that extends forward in the terminal body, and a stabilizer that is fixed by a lance of the housing. At the root end of the leaf spring, a round part that bends lengthwise into an approximately circular arc is formed. A bead having a curved section to increase flexural rigidity of the leaf spring is formed ahead of the round part on the top end side. A stabilizer having a face directed in the width direction is erected in the height direction from the top end of the terminal body.
