Abstract

It is aimed to prevent a reduction in connection reliability. A terminal fitting is to be mounted into a housing having a board accommodation space and is provided with a connection terminal including a resilient contact piece to be brought into contact with a circuit board inserted into the board accommodation space and a protection terminal separate from the connection terminal and attached to the connection terminal. The connection terminal is movable with respect to the protection terminal between a protection position where the resilient contact piece is accommodated in the protection terminal and a connection position where the resilient contact piece is exposed to outside of the protection terminal to be contactable with the circuit board.

First claim

What is claimed is:

1. A terminal fitting to be mounted into a housing having a board accommodation space, comprising:
a connection terminal including a resilient contact piece to be brought into contact with a circuit board inserted into the board accommodation space; and
a protection terminal separate from the connection terminal, the protection terminal being attached to the connection terminal,
the connection terminal being movable with respect to the protection terminal between a protection position where the resilient contact piece is accommodated in the protection terminal and a connection position where a contact portion of the resilient contact piece is exposed to outside of the protection terminal to be contactable with the circuit board,
the protection terminal including a guide surface for receiving a forward surface of the contact portion in the protection position and is configured to prevent the connection terminal from moving forward to the connection position when the forward surface of the contact portion is brought into contact with the guide surface of the protection terminal.

2. The terminal fitting of claim 1 , wherein:
the protection terminal is formed with a protecting portion, the resilient contact piece being brought into contact with the protecting portion from inside of the protection terminal when the connection terminal is at the protection position, and
the protecting portion is formed to hold the connection terminal not to move to the connection position by bringing the resilient contact piece into contact with the protecting portion.

3. The terminal fitting of claim 2 , wherein the protecting portion is so formed that the resilient contact piece is brought into surface contact with the protecting portion.

4. The terminal fitting of claim 2 , wherein:
the protecting portion has a guide surface, the resilient contact piece being brought into sliding contact with the guide surface, and
the protecting portion has the guide surface, the resilient contact piece being brought into sliding contact with the guide surface, and
the resilient contact piece slides in contact with the guide surface, thereby moving in a path where the resilient contact piece does not interfere with an inserting end part of the circuit board inserted into the board accommodation space, in the process of moving the connection terminal from the protection position to the connection position.

5. The terminal fitting of claim 1 , wherein the protection terminal is formed with a recess for preventing a contact point portion of the resilient contact piece from contacting the protection terminal when the connection terminal is at the protection position.

6. The terminal fitting of claim 1 , wherein:
one of the connection terminal and the protection terminal is formed with a guide groove parallel to a moving direction of the connection terminal, and
the other of the connection terminal and the protection terminal is formed with a guide projection to be brought into sliding contact with the guide groove in the process of moving the connection terminal between the connection position and the protection position.
