The tenth wall portion 1312a2 is located at the distal end of the transit terminal 1. In other words, the tenth fourth wall portion 1312a2 is located at an end of the fourth substrate 1312 remote from the fixing portion 12.

The sixth elastic piece 1322 extends from the thirteenth wall portion 1312a1 to the fourteenth wall portion 1312a2, and an end of the sixth elastic piece 1322 near the fourteenth wall portion 1312a2 is a free end. When the transit terminal 1 is abutted to a conductive terminal (e.g., the first conductive terminal 2), the free end of the sixth elastic piece 1322 can move along the first direction A1-A1 due to the abutment in the fourth frame-shaped piece 1312a.

Referring to fig. 5, the second spring portion 132 further includes an eighth spring 1324.

The eighth spring 1324 is located in the fourth frame-shaped member 1312 a. The eighth elastic piece 1324 extends from the fourth substrate 1312 along the second direction A2-A2, and the extending direction of the eighth elastic piece 1324 is opposite to the extending direction of the sixth elastic piece 1322.

Along the third direction A3-A3, the eighth elastic piece 1324 and the sixth elastic piece 1322 at least partially overlap.

In the illustrated embodiment, the number of the sixth elastic pieces 1322 is two. Along the third direction A3-A3, a fourth yielding space S4 exists between the two sixth elastic sheets 1322. The fourth space S4 is substantially V-shaped when viewed from one end of the first direction A1-A1. The eighth elastic piece 1324 extends into the fourth yielding space S4, and correspondingly, the eighth elastic piece 1324 includes a seventh inclined edge 1324b and an eighth inclined edge 1324c.

The eighth spring piece 1324 extends from the tenth wall portion 1312a2 to the thirteenth wall portion 1312a 1. One end of the eighth elastic piece 1324 near the thirteenth wall portion 1312a1 is a free end thereof. When the transit terminal 1 is abutted to a conductive terminal (e.g., the first conductive terminal 2), the free end of the eighth elastic piece 1324 can move along the first direction A1-A1 due to the pressing in the fourth frame-shaped piece 1312 a.

The eighth elastic piece 1324 includes an eighth elastic contact portion 1324a. The eighth elastic contact portion 1324a extends in the first direction A1-A1 to protrude from the fourth substrate 1312 in a direction away from the third substrate 1311.

Referring to fig. 7, the eighth elastic contact portion 1324a extends along the second arc-shaped surface β.

Referring to fig. 6, the eighth elastic contact portion 1324a includes a fourth abutting portion 1324a1 and a fourth guide section 1324a2.

The fourth abutment 1324a1 is configured to abut against an abutting conductive terminal (e.g., the first conductive terminal 2).

Along the second direction A2-A2, the fourth guiding section 1324A2 is located at one side or both sides of the fourth abutting portion 1324a 1. When the fourth guide section 1324a2 is located at a side of the fourth abutment 1324a1, the fourth guide section 1324a2 is located at a side of the fourth abutment 1324a1 near the distal end of the transit terminal 1.

The fourth guide section 1324a2 extends smoothly from the fourth abutment 1324a1 to the fourth substrate 1312 along the second arc-shaped surface β.

The sixth elastic sheet 1322 and the eighth elastic sheet 1324 are oppositely staggered, and have identical radians, so that the sixth elastic sheet and the eighth elastic sheet can protect each other, and the possibility of deformation in the transportation or use process is reduced.

Referring to fig. 4 and 6, the first guide section 1321a2, the second guide section 1322a2, the third guide section 1323a2, and the fourth guide section 1324a2 are first guides 1326 in the second butt joint 13. The first guide piece 1321a3 and the second guide piece 1322a3 are second guide portions 1327 in the second butt portion 13. The first contact portion 1321a1, the second contact portion 1322a1, the third contact portion 1323a1, and the fourth contact portion 1324a1 are contact portions 1325 in the second abutting portion 13.

The first elastic contact portion 1121a and the third elastic contact portion 1123a each extend along the third arc surface γ; the second elastic contact portion 1122a and the fourth elastic contact portion 1124a each extend along the fourth arc surface δ; the fifth elastic contact portion 1321a and the seventh elastic contact portion 1323a each extend along the first arc surface α; and the sixth elastic contact portion 1322a and the eighth elastic contact portion 1324a each extend along the second arc-shaped surface β. This form of extension along the arcuate surface in the illustrated embodiment allows the elastic contact portion to have a larger area of contact with the conductive terminal (the first conductive terminal 2 or the second conductive terminal 3) than if the elastic contact portion were provided in a form of extension along the spherical surface, which is more suitable for the case of conducting a large current.

Referring to fig. 3 and 5, the fixing portion 12 includes a first fixing wall 121, a second fixing wall 122 opposite to the first fixing wall 121, a first connecting wall 123 connecting one end of the first fixing wall 121 and one end of the second fixing wall 122, and a second connecting wall 124 connecting the other end of the first fixing wall 121 and the other end of the second fixing wall 122.

One end of the first fixing wall 121 is connected to the first substrate 1111, and the other end of the first fixing wall 121 is connected to the third substrate 1311 along the second direction A2-A2; one end of the second fixing wall 122 is connected to the second substrate 1112, and the other end of the second fixing wall 122 is connected to the fourth substrate 1312.

The first fixing wall 121 and the second fixing wall 122 are spaced apart from each other by a distance along the first direction A1-A1. This makes the fixing portion 12 more solid and easy to fix inside the connector (e.g., an insulating body fixed inside the connector).

In other words, referring to fig. 5, in the second direction A2-A2, the fixing portion 12 includes a first end surface 126 and a second end surface 127 opposite to the first end surface 126. The fixed part 12 further comprises a through cavity 125. The through cavity 125 extends through the first end face 126 and the second end face 127 in the second direction A2-A2.

Referring to fig. 7, a plane M exists between the third substrate 1311 and the fourth substrate 1312, and the transit terminal 1 is symmetrical with respect to the plane M.

The adapter terminal 1 according to the present utility model can be integrally formed by multiple stamping. The material of the transfer terminal 1 can be copper alloy. Referring to fig. 2, the adapter terminal 1 is connected to the second conductive terminal 3 by a flat first base 111 and a first spring piece 112 protruding outward from the first base 111; the adapter terminal 1 is connected with the first conductive terminal 2 through a flat second base 131 and a second spring piece part 132 protruding outwards from the second base 131, and has a simple structure. Further, referring to fig. 2 and 7, the entire transit terminal 1 may be spread substantially along the plane M (referring to fig. 2, the fixing portion 12 is spread along the zigzag fitting line A4). The entire process of stamping the adapter terminal 1 is easily known to those skilled in the art by unfolding the adapter terminal 1. The transit terminal 1 can be obtained by only punching for a plurality of times, which makes the manufacturing process of the transit terminal 1 simple and the manufacturing cost low.

The first abutment wall 211, the second abutment wall 212, the third connection wall 213 and the fourth connection wall 214 surround the first docking space 215.

The first connector portion 21 further has a first escape groove 216 and a second escape groove 217. The first avoidance groove 216 penetrates the third connecting wall 213 along a direction perpendicular to the third connecting wall 213, and the first avoidance groove 216 extends along the third direction A3-A3 and penetrates the first butt end surface 210. The second avoidance groove 217 penetrates the fourth connecting wall 214 along a direction perpendicular to the fourth connecting wall 214, and the second avoidance groove 217 extends along the third direction A3-A3 and penetrates the first butt end surface 210.

In the illustrated embodiment, the first conductive terminal 2 is plugged into the adapter terminal 1 in the third direction A3-A3. The first avoidance groove 216 and the second avoidance groove 217 avoid the second base 131. After plugging, the first abutting wall 211 and the second abutting wall 212 are pressed and buckled on the outer side of the second elastic piece portion 132 to realize electrical connection with the switching terminal 1.
