Abstract

A combination terminal (1) has a first terminal (10) overlapping a second terminal (110) in a plate thickness direction. The first terminal (10) includes a base (41) and two inclined walls (20) intersecting surfaces of the base (41) from both lateral ends of the base (41) and forming an insertion/accommodation space (C) having a trapezoidal shape. The second terminal (110) includes an inserting piece (132) that overlaps the base (41) when inserted into the insertion/accommodation space (C). A locking claw (132A) on the inserting piece (132) locks the base (41) by overlapping the inserting piece (132) on the base plate (41). An external force absorbing tapered portion (133) projects laterally from the inserting piece (132) and comes into surface contact with one of the inclined walls (42) with the locking portion (132A) locked to the base (41).

First claim

What is claimed is:

1. A combination terminal formed by overlapping a first terminal and a second terminal in a plate thickness direction, wherein:
the first terminal includes a base plate and two inclined walls extending obliquely away from one another in directions intersecting plate surfaces of the base plate from both lateral ends of the base plate and forming an insertion/accommodation space having a trapezoidal shape together with the base plate; and
the second terminal includes an inserting piece defining a plate with a plate surface arrangeable to overlap on the base plate by inserting the inserting piece into the insertion/accommodation space, a lock projecting from the plate surface of the inserting piece and to be locked to the base plate by the inserting piece being arranged to overlap on the base portion, and two external force absorbing tapered surfaces laterally extending obliquely from the plate surface of the inserting piece so that a plate thickness of the inserting piece gradually thins along the external force absorbing tapered surfaces, the two external force absorbing tapered surfaces being disposed and configured for coming into surface contact respectively with the two inclined walls when the lock is locked to the base plate.

2. The combination terminal of claim 1 , wherein:
the first terminal further includes two first flat plates coupled to the inclined walls and laterally extending;
the second terminal further includes two second flat plates having a plate shape and arrangeable to overlap on the first flat plates in a direction opposite to an overlapping direction of the inserting piece on the base plate;
the base plate is provided with a locking hole communicating with the insertion/accommodation space; and
the inserting piece is provided with a locking claw configured to project into the locking hole when the inserting piece is arranged to overlap on the base plate and lockable to the locking hole in a front-rear direction.

3. The combination terminal of claim 2 , wherein:
the second terminal further includes the coupling plate, coupling the second flat plates to each other and arranged behind the inclined walls, the inserting piece has a tab shape extending forward from the coupling plate and a separating slit is formed between the external force absorbing tapered portion and the coupling plate.

4. The combination terminal of claim 3 , wherein the first terminal includes a wire connecting portion provided on one of the first flat plates and extending laterally farther out than an outer side edge of one of the second flat plates and a rotation stop provided on the other of the first flat plates and extending laterally farther out than an outer side edge of the other of the second flat plates.
