Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, and in particular to a terminal, an electrical connector, and an electronic device. Background Technology

[0002] As a key component in electrical connectors, the technological development of terminals is related to the performance and reliability of electrical connectors. As the performance requirements of electrical connectors increase, the requirements for terminals also become higher.

[0003] However, the inventors of this utility model have discovered in practice that most electrical connectors on the market currently include an insulating body and a single-arm terminal disposed on the insulating body. The single-arm terminal includes a soldering part, an elastic arm, and a contact part connected in sequence. The soldering part is used to solder to the circuit board, and the contact part is located at the end of the elastic arm away from the soldering part. When the electrical connector needs to be connected to an external device, the contact part is first pressed against the external device, and then the electrical connector is pressed down towards the external device to bend the elastic arm. The bent elastic arm provides elasticity, so that the contact part can remain in contact with the external device. However, the conductivity between the contact part and the soldering part is transmitted through the elastic arm, and its conductivity path is equivalent to the length of the entire elastic arm, which is a relatively long conductivity path. Utility Model Content

[0004] In view of the above problems, the present invention provides a terminal, an electrical connector and an electronic device that overcome the above problems.

[0005] According to one aspect of the present invention, a terminal embodiment is provided. The terminal includes: a contact portion, a connecting portion, an elastic arm, a base, and a welding portion.

The base is connected to the end of the connecting portion away from the elastic arm. The base extends to have a straight section in the direction of the contact portion. The welding portion is connected to the base. When the contact portion is subjected to an external force to press down in the direction of the base, the elastic arm bends and deforms, and the abutment portion moves in the direction of the base. When the abutment portion abuts against the straight section, the abutment portion and the straight section form a conductive path.

[0006] In some embodiments, the abutment portion is formed by tearing the elastic arm toward the base from the side near the contact portion.

[0007] In some embodiments, the abutting portion is bent toward the connecting portion.

[0008] In some embodiments, the elastic arm is provided with a window, and one end of the abutment is connected to the inner wall of the window near the contact portion.

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.

[0019] Please see Figure 1 and Figure 2 The terminal includes a contact portion 1, a connecting portion 2, an elastic arm 3, a base portion 4, and a welding portion 5. The two ends of the elastic arm 3 are connected to the contact portion 1 and the connecting portion 2, respectively. The elastic arm 3 extends to have an abutment portion 31. The base portion 4 is connected to the end of the connecting portion 2 away from the elastic arm 3. The base portion 4 extends to have a straight strip portion 41 in the direction of the contact portion 1. The welding portion 5 is connected to the base portion 4. The welding part 5 is used to weld to the circuit board. When the welding part 5 is fixed and the contact part 1 is subjected to an external force toward the welding part, the contact part 1 is pressed down toward the base 4, the elastic arm 3 bends and deforms, and the abutment part 31 moves toward the base 4. When the abutment part 31 abuts with the straight bar part 41, the abutment part 31 and the straight bar part 41 form a conductive path. The conductive signal of the contact part 1 is transmitted to the base 4 through the abutment part 31 and the straight bar part 41, and then transmitted to the welding part 5 from the base 5. Compared with the conductive method of the elastic arm 3, the conductive path of this application is shorter.

[0020] The aforementioned abutting portion 31 is formed by tearing the elastic arm 3 towards the base 4 from the side near the contact portion 1. When the contact portion 1 is pressed down, the abutting portion 31 abuts against the straight strip portion 41. In some embodiments, the abutting portion 31 is bent towards the connecting portion 2, for example, the abutting portion 31 is curved.

[0021] Regarding the contact portion 1 described above, when the terminal abuts against the processor (not shown), the contact portion 1 abuts against the contact area of ​​the processor. In some embodiments, the contact portion 1 is bent toward the direction of the connecting portion 2. For example, the contact portion 1 is curved, and the curved back of the contact portion 1 is used to abut against the contact area of ​​the processor.

[0022] For the base 4 mentioned above, please refer to Figure 2 and Figure 3 The base 4 extends to one end away from the connecting part 2, and the extension 42 is bent and connected to the welding part 5.

[0023] In some embodiments, a notch (not shown) is provided at the end of the base 4 away from the connecting portion 2. The notch is adjacent to the extension portion 42. By adding the notch, it is beneficial for the extension portion 42 to bend. There are two notches, and the two notches are located on both sides of the extension portion 42. The two notches make it easier for the extension portion 42 to bend.

[0024] The elastic arm 3 described above is made of a material with elastic deformation capability, such as copper, aluminum, iron, etc. In some embodiments, the elastic arm 3 is pre-set to have a small bending radius, and the shape of the bending radius can be arc-shaped or V-shaped, etc.

[0025] Please see Figure 3 In some embodiments, the abutment portion 31 is formed by tearing a portion of the elastic arm 3 toward the contact portion 1. The elastic arm 3 is provided with a window (not shown). One end of the abutment portion 31 is connected to the inner wall of the window near the contact portion 1. After the terminal is pressed down, the abutment portion 31 abuts against one end of the straight strip portion 41 to form a conductive path.

[0026] In this embodiment of the utility model, the terminal includes a contact portion 1, a connecting portion 2, an elastic arm 3, a base 4, and a welding portion 5. The two ends of the elastic arm 3 are respectively connected to the contact portion 1 and the connecting portion 2. An abutment portion 31 extends from the side of the elastic arm 3 near the contact portion 1. The base 4 is connected to the end of the connecting portion 2 away from the elastic arm 3. A straight strip portion 41 extends from the base 4 toward the contact portion 1. The welding portion 5 is connected to the base 4. When the contact portion 1 is subjected to an external force, causing the contact portion 1 to be pressed down toward the base 4, the elastic arm 3 bends and deforms, and the abutment portion 31 moves toward the base 4. When the abutment portion 31 abuts against the straight strip portion 41, the abutment portion 31 and the straight strip portion 41 form a conductive path. A shorter conductive path is beneficial to improving the signal transmission performance of the terminal.
