Abstract

A terminal crimping apparatus includes a terminal supply device configured to supply a terminal chain member including a plurality of crimping terminals, a first mold including a first edge portion provided at one end of a supporting surface supporting the crimping terminals, a second mold configured to crimp the crimping terminal onto a wire by sandwiching the crimping terminal between the second mold and the supporting surface, and a terminal cutting member including a second edge portion. The terminal cutting member cuts a boundary with the crimping terminal in a link portion using the second edge portion.

First claim

What is claimed is:

1. A terminal crimping apparatus comprising:
a terminal supply device configured to supply a terminal chain member including a plurality of crimping terminals arranged in parallel extending in a length direction, a joint piece extending in an arrangement direction of the plurality of crimping terminals arranged perpendicular to the length direction, and link portions linking one ends of the crimping terminals and the joint piece;
a first mold including a supporting surface supporting the crimping terminals supplied by the terminal supply device and a first edge portion provided at one end of the supporting surface;
a second mold disposed to face the supporting surface and configured to crimp the crimping terminal onto a wire by sandwiching the crimping terminal and the wire between the second mold and the supporting surface while relatively moving along a height direction with respect to the supporting surface of the first mold; and
a terminal cutting member disposed adjacently to the first mold and including a second edge portion corresponding to the first edge portion, wherein
the terminal cutting member cuts a boundary with the crimping terminal in the link portion using the second edge portion in cooperation with the first edge portion while relatively moving along the height direction with respect to the first mold,
the second mold includes a main body and a pair of wall portions protruding from the main body toward the first mold and facing each other in the arrangement direction of the crimping terminals and configured to come into contact with the crimping terminal to bend the crimping terminal when the second mold relatively moves along the height direction with respect to the supporting surface of the first mold,
the pair of wall portions include proximal end portions provided on a main body side of the main body facing the terminal cutting member and hem portions provided on a distal end side of the main body provided further from the terminal cutting member than the proximal end portions, and
the main body and the proximal end portions protrude further toward the terminal cutting member compared to the first edge portion of the first mold, and the hem portions are positioned closer to the first mold than the first edge portion of the first mold.

2. The terminal crimping apparatus according to claim 1 , wherein
the hem portions are provided in a range set according to a movement distance by which the second mold relatively moves along the height direction with respect to the terminal cutting member when the crimping terminal is crimped.

3. The terminal crimping apparatus according to claim 2 , wherein
the terminal cutting member includes a protruding portion to be inserted into a hole portion included in the joint piece to position the crimping terminal.

4. The terminal crimping apparatus according to claim 3 , wherein
a surface on the terminal cutting member facing the first mold includes a groove portion being a pathway of the joint piece, and
a guide portion configured to guide the joint piece to adjust a position of the crimping terminal is provided in an opening portion on a side of the groove portion facing the first mold.

5. The terminal crimping apparatus according to claims 2 , wherein
a surface on the terminal cutting member facing the first mold includes a groove portion being a pathway of the joint piece, and
a guide portion configured to guide the joint piece to adjust a position of the crimping terminal is provided in an opening portion on a side of the groove portion facing the first mold.

6. The terminal crimping apparatus according to claim 1 , wherein
the terminal cutting member includes a protruding portion to be inserted into a hole portion included in the joint piece to position the crimping terminal.

7. The terminal crimping apparatus according to claim 6 , wherein
a surface on the terminal cutting member facing the first mold includes a groove portion being a pathway of the joint piece, and
a guide portion configured to guide the joint piece to adjust a position of the crimping terminal is provided in an opening portion on a side of the groove portion facing the first mold.

8. The terminal crimping apparatus according to claim 1 , wherein
a surface on the terminal cutting member facing the first mold includes a groove portion being a pathway of the joint piece, and
a guide portion configured to guide the joint piece to adjust a position of the crimping terminal is provided in an opening portion on a side of the groove portion facing the first mold.
