Terminal, chain terminal, and connector

1. A terminal arranged in a housing, comprising:

a terminal connection part that is to be connected to a counterpart terminal and includes a bottom plate, the bottom plate having a bottom surface opposite the housing and an upper surface that is an opposite surface from the bottom surface;

a concave groove having an inclined surface extending upward from a front edge of the bottom surface;

a carrier cut part extending downward from a front edge of the upper surface; and

a projection having a basal end and a tip end, the basal end being continuous with the lower end of the carrier cut part and with the front end of the concave groove, the tip end being located above a level of the bottom surface.

2. The terminal according to claim 1 , wherein

the terminal connection part includes the bottom plate, a ceiling plate that faces the bottom plate, and a pair of side plates coupling between both side edges of the bottom plate and both side edges of the ceiling plate, the terminal connection part having a tubular shape into which the counterpart terminal can be inserted,

the side plate includes a concave part with a recessed shape at an end part on a side of the bottom plate at an edge of the side plate on a side where the counterpart terminal is inserted, and

the carrier cut part is provided at the edge of the bottom plate that projects in the concave part at the bottom plate.

3. The terminal according to claim 2 , wherein the side plate includes an elastic piece that is in elastic contact with the counterpart terminal.

4. The terminal according to claim 1 , further comprising a reinforcement part that reinforces the bottom plate in a part of the bottom plate where the carrier cut part is provided.

5. A chain terminal comprising:

a plurality of terminals each including terminal connection parts with bottom plates;

a carrier having a belt shape, the carrier including coupling parts extending from a long edge of the carrier adjacent to the plurality of terminals to the bottom plates, respectively;

cutting portions each including end portions of the bottom plates and distal end portions of the respective coupling parts with bottom surfaces each including bottom surfaces of the end portions of the bottom plates and bottom surfaces of the distal end portions of the respective coupling parts, each of the cutting portions including a concave groove in one of the bottom surfaces at a border between one of the end portions and one of the distal end portions, the concave groove extending for an entire length of the one of the distal end portions; and

a reinforcement part in the bottom plate and the carrier, the reinforcement part reinforcing a part where the concave groove is provided, the reinforcing part extending in a direction in which the terminal and the carrier are to be coupled together, the reinforcement part projecting in a thickness direction of the bottom plate.

6. The chain terminal according to claim 5 , wherein the concave groove is larger in a direction where the terminal and the carrier are coupled than a plate thickness of the bottom plate and is formed along an entire width of the border between the bottom plate and the carrier.

7. The chain terminal according to claim 5 , wherein the concave groove is smaller in a direction where the terminal and the carrier are coupled than a plate thickness of the bottom plate and is formed along an entire width of the border between the bottom plate and the carrier.

8. A connector comprising:

the terminal according to claim 1 ; and

a housing that contains the terminal.
