[0019] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0020] Please see Figure 1The elastic terminal 1 includes a first base 2, a second base 3, an elastic part 4, a contact part 5, a fixing part 6, a straight part 7, and an abutment part 8. The second base 3 and the first base 2 are disposed opposite to each other. The two ends of the elastic part 4 are respectively connected to the first base 2 and the second base 3. The elastic part 4 is bent and is used to supply elastic force. The contact portion 5 is fixed to the side of the first base 2 away from the elastic portion 4, the fixing portion 6 is fixed to the side of the second base 3 away from the elastic portion 4, one end of the straight portion 7 is fixed to the first base 2, and the other end of the straight portion 7 extends toward the second base 3, one end of the abutting portion 8 is fixed to the second base 3, and the other end of the abutting portion 8 extends toward the first base 2. When the elastic portion 4 is in an uncompressed state, the ends of the other end of the straight portion 7 and the other end of the abutting portion 8 are spaced apart. When the elastic portion 4 is in a compressed state, the other end of the straight portion 7 abuts against the other end of the abutting portion 8. The straight portion 7 and the abutting portion 8 form a straight conductive path.

[0021] The elastic portion 4 described above has elastic deformation properties. When compressed, it undergoes compressive deformation, and when uncompressed, it recovers its original shape. In some embodiments, there may be two elastic portions 4. One end of each elastic portion 4 is connected to both ends of the first base 2, and the other end of each elastic portion 4 is connected to both ends of the second base 3. The straight section 7 and the abutment portion 8 are both located between the two elastic portions 4. The abutment portion 8 is located in the middle of the first base 2. When the elastic terminal 1 is inserted into an external device, the abutment portion 8 evenly distributes the pressure to the two elastic portions 4, which helps maintain the overall compression of the elastic terminal 1, reduces the risk of lateral bending of the elastic terminal 1, and helps improve the reliability of the elastic terminal 1.

[0022] In some embodiments, the number of elastic portions 4 is one, the straight portion 7 and the abutting portion 8 are located on one side of the elastic portion 4, and the elastic portion 4 is compressed when pressed.

[0023] For the aforementioned abutment part 8, please refer to... Figure 2 and Figure 3 The abutting part 8 includes a first bending arm 81, one end of which is connected to the second base 3, and the other end of which is provided with a first bending part 811. When the elastic part 4 is in a compressed state, the first bending part 811 abuts against the straight part 7.

[0024] In some embodiments, the abutment portion 8 further includes a second bent arm 82, one end of which is connected to the second base portion 3, and the other end of which is provided with a second bent portion 821. The second bent portion 821 and the first bent portion 811 bend in the same direction. The first bent portion and the second bent portion 821 together form a flared opening. The flared opening is aligned with the straight section portion 7 and is used for the straight section portion 7 to be inserted. The first bent portion 811 and the second bent portion 821 abut against both sides of the straight section portion 7, which helps to maintain the abutment against the straight section portion 7.

[0025] In some embodiments, the abutting portion 8 further includes a third bent arm 83, one end of which is connected to the second base portion 3, and the other end of which is provided with a third bent portion 831. The third bent portion 831 is located between the first bent portion 811 and the second bent portion 821. The third bent portion 831 abuts against one side of the straight portion 7, and the first bent portion 811 and the second bent portion 821 abut against the other side of the straight portion 7, thereby achieving three-point abutment and a better abutment effect.

[0026] In some embodiments, the abutting portion 8 includes only a first bent arm 81 and a third bent arm 83. The first bent portion 811 of the first bent arm 81 and the third bent portion 831 of the third bent arm 83 form a scissor cut. The straight portion 7 is inserted into the scissor cut, and the first bent portion 811 and the third bent portion 831 abut against both sides of the straight portion 7.

[0027] Please see Figure 5 In some embodiments, the abutment portion 8 further includes a straight arm 84, one end of which is connected to the second base portion 3. One end of the first bent arm 81, the second bent arm 82, and the third bent arm 83 are all connected to the other end of the straight arm 84. By providing the straight arm 84, the length of the first bent arm 81, the second bent arm 82, and the third bent arm 83 can be minimized so that the transmission path remains as straight as possible.

[0028] Furthermore, the straight arm 84 has opposing first surfaces 841 and second surfaces (not shown), a portion of the first surface 841 being recessed toward the second surface to form a first groove 8411 on the first surface 841 and a first protrusion (not shown) on the second surface; and / or, a portion of the second surface being recessed toward the first surface 841 to form a second groove (not shown) on the second surface and a second protrusion 8412 on the first surface 841. The straight section 7 has opposing third surfaces 71 and fourth surfaces 72. A portion of the third surface 71 is recessed toward the fourth surface 72 to form a third groove 711 on the third surface 71 and a third protrusion 712 on the fourth surface 72; and / or, a portion of the fourth surface 72 is recessed toward the third surface 71 to form a fourth groove 721 on the fourth surface 72 and a fourth protrusion 722 on the third surface 71. The opposing first, second, third, and fourth grooves and the opposing first, second, third, and fourth protrusions help to disperse the stress generated when the resilient terminal 1 is inserted into the insulating body 91.

[0029] In this embodiment of the invention, the elastic terminal 1 includes a first base 2, a second base 3, an elastic portion 4, a contact portion 5, a fixing portion 6, a straight portion 7, and an abutment portion 8.

A base 2, the other end of the straight section 7 extends toward the second base 3, one end of the abutting part 8 is fixed to the second base 3, and the other end of the abutting part 7 extends toward the first base 2. When the elastic part 4 is in an uncompressed state, the end of the other end of the straight section 7 and the end of the other end of the abutting part 8 are spaced apart. When the elastic part 4 is in a compressed state, the other end of the straight section 7 abuts against the other end of the abutting part 8.
