Abstract

A female terminal fitting (F) has a terminal main body (10) with an inserting portion (11) that has two opposed resilient contacts (17) for receiving a male terminal fitting (M). A mounting member (30) is mountable sideways onto the inserting portion (11). The mounting member (30) has a base (31) and two supports (32) that extend in a widthwise direction from opposite ends of the base (31). The supports (32) are located to support the outer surfaces of the resilient contacts (17) opposite from contact surfaces (17a) with the male terminal fitting (M).

Claims

1. A female terminal fitting extending along a longitudinal direction and defining opposite front and rear ends, the female terminal fitting comprising:

a substantially tubular portion between the front and rear ends;

first and second substantially opposed resilient contacts extending from the tubular portion substantially to the front end of the female terminal fitting, the resilient contacts having opposed inner surfaces substantially facing one another and opposite outer surfaces facing away from one another, the inner surface of each of said resilient contacts having a contact surface for contacting a mating male terminal fitting;

opposed sidewalls angularly aligned to the resilient contacts and extending forward from the tubular portion, each sidewall being joined to at least one of the resilient contacts substantially at the front end of the female terminal fitting; and

a substantially U-shaped mounting member formed separately from the resilient contacts and having a base extending substantially transverse to the longitudinal direction at a location substantially aligned with the contact surfaces of the resilient contacts, the base contacting an outer surface of one of the sidewalls, the mounting member further having first and second supports projecting from the base and substantially transverse to the longitudinal direction, the supports engaging and supporting the outer surfaces of the resilient contacts substantially opposite the contact surfaces so that the supports enhance resilient forces of the resilient contacts.

2. The female terminal fitting of claim 1, wherein the resilient contacts are formed on a terminal main body, and wherein the terminal main body includes at least one positioning portion engageable with the mounting member to position the mounting member.

3. The female terminal fitting of claim 2, wherein:

a substantially box-shaped cover is mounted on a portion of the terminal main body where the resilient contact is provided.

4. The female terminal of claim 3, wherein the cover has an insertion hole into which the mounting member is insertable and a filling hole into which a leading end of the supporting piece is fittable.

5. The female terminal fitting of claim 1, wherein each of the resilient contacts includes a bent portion projecting inward, the contact surfaces being on the bent portions, and the supports being on outer sides of the bent portions.

6. The female terminal of claim 1, wherein each of the opposed sidewalls comprise first and second resilient reinforcements spaced from one another and extending forward from the tubular portion.

7. The female terminal fitting of claim 6, wherein the first reinforcement of each of said sidewalls is joined unitarily to the first resilient contact substantially at the front end of the terminal filling and the second reinforcement of each of the opposed sidewalls is joined unitarily to the second resilient contact substantially at the front end of the female terminal filling.

8. The female terminal fitting of claim 7, wherein the resilient contacts and the sidewalls comprise at least part of a terminal main body, the female terminal fitting further comprising fixing means for fixing the mounting member to the terminal main body.

9. The female terminal fitting of claim 1, wherein the sidewalls are spaced from resilient contacts at all locations between a substantially tubular portion and the connection of the sidewalls to the resilient contacts substantially at the front end of the terminal fitting.

10. The female terminal fitting of claim 1, wherein the supports of the mounting member are substantially planar.

11. The female terminal fitting of claim 1, wherein the mounting member is between the substantially tubular portion and the contact surfaces.
