Correspondingly, the first wire pressing assembly further comprises a third elastic element, a first hook plate is arranged at the first end of the first wire pressing plate, a second hook plate is arranged at the first end of the first vertical groove, the first end of the third elastic element is connected with the first hook plate, and the second end of the third elastic element is connected with the second hook plate. The third elastic element can achieve the same technical effects as the fourth elastic element 53, and will not be described in detail herein.

Optionally, a second end of the second wire pressing plate 52 is provided with a second locking tooth 522, and in a case that the second wire 6 is provided in the second wire inlet hole 311, the second locking tooth 522 abuts against the second wire 6.

Wherein the second end of the second tension plate 52 is provided with a second locking tooth 522. The second locking tooth 522 may increase friction between the second tension plate 52 and the conductive wire, so that contact between the conductive wire and the second conductive plate 32 may be secured. The second locking tooth 522 may be a triangular tooth surface or other tooth surface having a concave-convex structure, and may satisfy a requirement that a friction force between the second tension plate 52 and the wire may be increased, and a specific locking tooth structure is not limited herein.

Correspondingly, the second end of the first wire pressing plate can be provided with a first locking tooth, and under the condition that the first wire inlet hole is provided with a first wire, the first locking tooth is abutted to the first wire. The first locking tooth can achieve the same technical effect as the second locking tooth 522, and is not described in detail herein.
