Abstract

An object of the present invention is to provide a terminal fitting with improved waterproof property. A terminal fitting (10) includes a box-shaped main portion (21), barrel portions (22, 23) to be crimped and connected to a core (91) at an end portion of a wire (90), a waterproof wall (60) to be mounted between the barrel portions (22, 23) and the main portion (21) to partition between them in a liquid-tight manner, a restricting portion (25) configured to restrict a movement of the waterproof wall (60) toward the main portion (21) by coming into contact with the waterproof wall (60) from the main portion (21) side and a heat shrinkable tube (70) to be held in close contact with the barrel portions (22, 23) and the waterproof wall (60) while surrounding the core (91).

Claims

1. A terminal fitting, comprising:

a main portion connectable to a mating terminal fitting;

a barrel portion to be crimped and connected to a core at an end portion of a wire;

a waterproof wall to be mounted between the barrel portion and the main portion to partition between the barrel portion and the main portion in a liquid-tight manner;

a restricting portion configured to restrict a movement of the waterproof wall toward the main portion by coming into contact with the waterproof wall from the main portion side; and

a tube to be held in close contact with the barrel portion and the waterproof wall while surrounding the core.

2. The terminal fitting of claim 1, wherein the restricting portion is formed by being bent from a coupling portion located between the main portion and the barrel portion.

3. The terminal fitting of claim 2, wherein the restricting portion includes a first restricting portion which comes into contact with the waterproof wall from the main portion side and a second restricting portion which comes into contact with the waterproof wall from the barrel portion side.

4. The terminal fitting of claim 3, wherein a space into which the waterproof wall is to be positioned and inserted is formed between the first and second restricting portions.

5. The terminal fitting of claim 1, wherein the restricting portion includes a first restricting portion which comes into contact with the waterproof wall from the main portion side and a second restricting portion which comes into contact with the waterproof wall from the barrel portion side.

6. The terminal fitting of claim 5, wherein a space into which the waterproof wall is to be positioned and inserted is formed between the first and second restricting portions.
