The terminal 1 includes a main body 11, an elastic arm 12 and a first support arm 13. The main body 11 is used for the corresponding terminal to be plugged in. One end of the elastic arm 12 is fixed to the main body 11, and the elastic arm 12 extends into the main body 11. The elastic arm 12 and the main body 11 are used together to provide a retaining force to connect the corresponding terminal plugged into the main body 11 with the terminal 1. One end of the first support arm 13 is fixed to the main body 11, and the first support arm 13 extends into the main body 11. The other end of the first support arm 13 is used to support the other end of the elastic arm 12.

[0028] In some embodiments, the terminal 1 is made of metal.

[0029] For the above subject 11, see Figure 2 The main body 11 is provided with a slot 111, a plurality of first contact portions 112, a plurality of third contact portions 113, an opening 114 and a clamping portion 115. The slot 111 is provided at one end of the main body 11, and the slot 111 is used for plugging in the corresponding terminal 1. A plurality of first contact portions 112 are protruding from the third side wall of the slot 111, and the plurality of first contact portions 112 are arranged at intervals, and the first contact portions 112 are used to abut against the corresponding terminals. A plurality of third contact portions 113 are protruding from the third side wall of the slot 111, and the plurality of third contact portions 113 are arranged at intervals, and the third contact portions 113 are located on one side of the first contact portion 112, and the third contact portions 113 are close to the notch of the slot 111, and the third contact portions 113 are used to abut against the corresponding terminals. The opening 114 is provided on the first side wall of the slot 111, and the first side wall is opposite to the third side wall, and the opening 114 is connected to the slot 111. The clamping portion 115 is disposed at one end of the main body 11 , and the clamping portion 115 is used to clamp with the clamping arm 23 of the insulating body 2 .

[0030] In some embodiments, the height b of the third contact portion 113 is greater than the height a of the first contact portion 112, so that when the corresponding terminal is tilted and inserted into the slot 111, the corresponding terminal can abut against the multiple first contact portions 112 and the multiple third contact portions 113, thereby allowing the corresponding terminal to maintain good contact with the multiple first contact portions 112 and the multiple third contact portions 113.

[0031] For the above-mentioned elastic arm 12, see Figure 2 The elastic arm 12 has elastic force and extends into the slot 111. The elastic arm 12 is formed by bending and extending the main body 11. The other end of the elastic arm 12 is provided with a second contact portion 121. The second contact portion 121 protrudes from the surface of the other end of the elastic arm 12 facing the third side wall. The second contact portion 121 is opposite to the first contact portion 112 and the third contact portion 113. The second contact portion 121 is used to abut the corresponding terminal.

[0032] In some embodiments, the second contact portion 121 is produced by a stamping process, so that the second contact portion 121 protrudes from the surface of the other end of the elastic arm 12 facing the first side wall.

[0033] For the first support arm 13, see Figure 2 One end of the first support arm 13 is fixed to the second side wall of the opening 114.
