Detailed Description

Specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the disclosure, are not intended to limit the disclosure.

In the present disclosure, unless otherwise stated, "inner", "outer" are with respect to the own outline of the corresponding parts, and furthermore, the terms "first", "second", etc. are used in the present disclosure to distinguish one element from another, without having order or importance. In the present disclosure, when the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements unless otherwise indicated.

Referring to fig. 1 to 4, the present disclosure provides a female terminal for plugging with a male terminal, where the female terminal may include a female terminal body 1, opposite sides of a connection end of the female terminal body 1 are respectively provided with a first elastic piece 21 and a second elastic piece 22 extending along a plugging direction, the first elastic piece 21 and the second elastic piece 22 are respectively in a cantilever structure, a side edge of the first elastic piece 21 is connected with a first bending portion 31 bending toward the second elastic piece 22, and a side edge of the second elastic piece 22 is connected with a second bending portion 32 bending toward the first elastic piece 21.

In some embodiments, referring to fig. 3, a gap is provided between the first bending portion 31 and the second elastic piece 22, and a gap is provided between the second bending portion 32 and the first elastic piece 21. In this way, the first elastic piece 21 is disconnected from the second elastic piece 22, so that the insertion force of the male terminal can be reduced, and the difficulty in installation can be reduced.

Specifically, referring to fig. 3, the first bending portion 31 and the second bending portion 32 may be disposed on opposite sides of the female terminal body 1, respectively, so that the first elastic sheet 21, the second elastic sheet 22, the first bending portion 31 and the second bending portion 32 can cover respective sides of the male terminal, so as to achieve better electrical connection.

As an exemplary embodiment of the present disclosure, referring to fig. 3, the cross sections of the first bending portion 31 and the second bending portion 32 may be gradually increased along the insertion direction of the male terminal, such that the distance between the head of the bending portion and the elastic piece is large, so that the male terminal is easily inserted at the beginning; the distance between the tail part of the bending part and the elastic piece is smaller, so that the contact pressure between the elastic piece and the male terminal can be increased.

According to some embodiments, referring to fig. 1, the female terminal may further include a housing 4 sleeved outside the female terminal body 1, and the female terminal body 1 and the housing 4 may be detachably connected through a locking structure. The locking structure can restrict the displacement of the female terminal body 1 with respect to the housing 4.

Wherein, referring to fig. 2, the locking structure may include a locking groove 11 formed on the female terminal body 1 and a buckle 41 disposed on the housing 4 for cooperating with the locking groove 11, wherein the buckle 41 is disposed at an end of the housing 4 away from the contact 23 of the spring. The female terminal body 1 can be stably fixed in the housing 4 by the snap 41 being snapped into the snap groove 11 to clamp the female terminal body 1.
