## Abstract

A connection terminal includes a conductive terminal main body having a female connection body, and a contact member arranged to oppose an inner circumferential surface of the female connection body in one region of an internal space. A first bulging body and a second bulging body protruding from the inner circumferential surface and electrically connected to a male connection body by sandwiching the male connection body with the contact member are provided in the other region of the internal space. The second bulging body has a first guide portion guiding the male connection body while sliding the male connection body, and a second guide portion guiding the contact member while sliding the contact member. Each of the first and second guide portions is formed in a tapered shape.

## Claims

### Claim 1

A connection terminal comprising:
a conductive terminal main body that includes a female connection body provided with a columnar internal space into which a male connection body of a mating male terminal is inserted, and a wire connection body to which a conducting portion of an electric wire is electrically connected; and
a contact member that is arranged to oppose an inner circumferential surface of the female connection body in one region of the internal space partitioned into two regions along an insertion/removal direction of the male connection body, is electrically connected to the female connection body on the inner circumferential surface of the female connection body, and is electrically connected to the male connection body inserted into the internal space from a first opening of the female connection body, wherein
a first bulging body and a second bulging body each of which protrudes from the inner circumferential surface of the female connection body and is electrically connected to the male connection body by sandwiching the male connection body, completely accommodated in the internal space, with the contact member are provided, respectively, on a side of the first opening and a side of a second opening in the other region of the partitioned internal space,
the second bulging body has a first guide portion capable of guiding the male connection body while sliding the male connection body in a process of inserting the male connection body into the internal space, and a second guide portion capable of guiding the contact member while sliding the contact member in a process of inserting the contact member into the internal space from the first opening, and
each of the first guide portion and the second guide portion is formed in a tapered shape so as to have an interval with respect to the one region of the partitioned internal space that is larger on the first opening side than on the second opening side.

### Claim 2 (depends on 1)

The connection terminal according to claim 1, wherein
the first bulging body and the second bulging body are arranged two by two at intervals in a circumferential direction of the inner circumferential surface of the female connection body.

### Claim 3 (depends on 1)

The connection terminal according to claim 1, wherein
the contact member includes first and second female-side contact portions which are arranged to be spaced apart from each other in the insertion/removal direction and are electrically connected to the inner circumferential surface of the female connection body, and a male-side contact portion that couples the first and second female-side contact portions and is electrically connected to the male connection body inserted into the internal space.

### Claim 4 (depends on 2)

The connection terminal according to claim 2, wherein
the contact member includes first and second female-side contact portions which are arranged to be spaced apart from each other in the insertion/removal direction and are electrically connected to the inner circumferential surface of the female connection body, and a male-side contact portion that couples the first and second female-side contact portions and is electrically connected to the male connection body inserted into the internal space.
