Description of the invention: - [Technical field to which the invention pertains] - The present invention relates to an electrical component, and more particularly to an elastic conductive terminal for achieving electrical connection between electronic components. [Prior Art] The host and battery of an electronic device such as a mobile phone are usually connected by a chip connector, and the printed circuit board and the printed circuit board are usually connected by wires between the printed circuit board and other electronic components. . The chip connector is bent by a metal sheet, and its elasticity is not strong. After a period of use, the elasticity is insufficient and the contact is unstable, which affects the use of electronic devices such as mobile phones. Moreover, the chip electronic connector occupies a large space, which is not conducive to the development of electronic devices such as mobile phones in the direction of miniaturization, which deviates from the development direction of market demand. The connection method of the electric wire is limited by the length of the electric wire, so it is easy to be entangled during use, which is inconvenient to use; in addition, at the time of installation, it is necessary to fix the two ends of the electric wire to the printed circuit board or the electronic component by welding or the like. On the other hand, it is more complicated, and the wire connection has problems such as complicated structure and beautiful appearance. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a conductive terminal that is easy to install and has good contact and stability. A conductive terminal comprising a sleeve, an elastic member, a contact member and an abutting member. The sleeve is cylindrical and has one end closed and an opening at the other end. The elastic member is received in the sleeve, and one end of the elastic member abuts against the closed end of the sleeve. 1289376 The contact element portion is housed within a sleeve that is movable relative to the sleeve. The abutting member is received in the sleeve between the elastic member and the contact member, and the abutting member and the contact member respectively comprise a contact surface abutting each other, and the elastic force of the abutting member by the elastic member Push the contact element diagonally. Compared with the prior art, the abutting component of the conductive terminal is pushed against the contact component, so that the sleeve and the contact component are in good contact, so that the electronic components connected by the conductive terminals or between the printed circuit boards are maintained. Good electrical ι connection. [Embodiment] The conductive terminal of the present invention is mainly applied to electronic products such as mobile phones, game machines, and broadcasters (e.g., MP3). Referring to FIG. 2 and FIG. 2, the conductive terminal 2〇 according to the first embodiment of the present invention can be used for electrically connecting two electronic components, including a sleeve 22, an elastic member 24, a contact member 26, and an Catch the ball 28. The sleeve 22 is cylindrical and includes a plurality of cylinders having different outer diameters. The sleeve 22 is made of a metal material, and its inner and outer surfaces are gold plated. The sleeve 22 includes a first end 222 and a second end 224 opposite the first end 222. The first end 222 of the sleeve 22 is closed and the second end 224 defines an opening 226. The sleeve 22 further includes a flange portion 228. After the conductive terminal 20 is mounted on an electronic device or the like, the flange portion 228 functions as a limit when the conductive terminal 2 is mounted to an electronic device or the like. The sleeve 22 is hollowed out to form a receiving cavity 229' in the sleeve 22. The receiving cavity 229 communicates with the outside of the sleeve 22 through the opening 226. The receiving cavity 229 is for receiving the elastic member 24, the abutting ball 28 and the contact member 7 J289376 26. The contact member 26 is partially received in the accommodating chamber 229, and is movable relative to the sleeve 22 such that another portion can extend out of the sleeve 22 or be received in the sleeve -22, and the abutting ball 28 is located at the elastic member 24. Between the contact element 26. The elastic member 24 is a columnar compressed magazine whose end face is a flat end surface, and includes a plurality of coils. In the present embodiment, all the coils have the same size. One end of the elastic member 24 abuts against the bottom of the accommodating cavity 229 of the sleeve 22, i.e., near the first end 222, and the other end of the elastic member 24 abuts against the abutting ball 28. When the conductive terminal 0 20 is assembled, the elastic member 24 is in a compressed state. The contact element 26 includes a base 262 and a contact portion 264. The base portion 262 and the contact portion 264 are cylindrical, and the base portion 262 has a diameter larger than the diameter of the contact portion 264, so that a shoulder portion 266 is formed at the junction of the base portion 262 and the contact portion 264. The base 262 is slightly smaller in diameter than the inner diameter of the sleeve 22. The base 262 has a contact surface 268 opposite to the contact portion 264. In the present embodiment, the contact surface 268 is a sloped surface, and the contact surface 268 abuts against the abutting ball 28. The abutment ball 28 is urged obliquely against the contact portion 264 of the contact member 26 by the elastic force of the elastic member 24, so that the contact portion 264 projects from the opening 226 of the sleeve 22 to the sleeve 22. The contact element 26 is made of a metallic material and its surface is gold plated. The abutment ball 28 is a spherical body having a diameter slightly larger than the inner diameter of the coil of the elastic member 24, so that the abutting ball 28 abuts against the end of the elastic member 24 without being completely rolled into the space formed by the coil. The abutment ball 28 has a contact surface that abuts the contact surface 268 of the contact element 26, and the contact surface is a spherical surface. During assembly, the elastic member 24, the abutting ball 28 and the contact portion 264 of the contact member 26 are sequentially placed in the accommodating cavity 229 of the sleeve 22, and the second end 224 of the sleeve 22 is bent inwardly. Thus, the opening 226 of the sleeve 22 is smaller than the base 262 of the contact member 26 of the 8 1289376, whereby the shoulder 266 of the contact member 26 - against the edge of the opening 226 of the sleeve 22 prevents the base 262 from extending out of the sleeve - 22 outside. The contact element 26 and the abutment ball 28 are urged by the elastic force of the elastic member 24 to generate a tendency to move in the axial direction of the sleeve 22 in the accommodating cavity 229 of the sleeve 22. Since the contact surface of the abutting ball 28 is a spherical surface, and because the inclined surface of the contact member 26 is present, even if the end surface of the elastic member 24 is a flat end surface, the contact member 26 can be tilted under the abutment of the abutting ball 28, so that The sleeve 22 _ is in good contact with the base 262 of the contact element 26 to maintain a good electrical connection between the electronic components connected by the conductive terminals 20 or between the printed circuit boards. When the conductive terminal 20 is applied, the flange portion 228 of the sleeve 22 is locked into a casing of an electronic product such as a mobile phone, and is movable in the axial direction of the conductive terminal 20 in the casing, and the sleeve of the conductive terminal 20 The first end 222 slidably abuts a member, and the end of the contact portion 264 of the contact member 26 slidably abuts the other member to electrically connect the two members. Referring to FIG. 3 and FIG. 4, the conductive terminal 40 of the second embodiment of the present invention includes a sleeve 42, an elastic member 44, a contact member 46 and an abutment post 48. The conductive terminal 40 is identical to the conductive terminal 20 except for the abutment post 48, i.e., the sleeve 42 is identical to the sleeve 22, the resilient member 44 is identical to the resilient member 24, and the contact member 46 is identical to the contact member 26. The abutment post 48 includes an abutment portion 482 and a set of segments 484. The abutting portion 482 is composed of a cylinder and a half sphere. The plane of the hemisphere is attached to the end surface of the cylinder, and the diameter of the hemisphere is the same as the diameter of the cylinder. The hemisphere of the abutting portion 482 of the abutting post 48 is a contact surface with the contact member 46 abutting 9 and 1289376, and the contact surface is a spherical surface. The nesting section 484 has a cylindrical shape, and one end thereof is in contact with the other end surface of the cylindrical body of the abutting portion 482. The cross-sectional diameter of the splicing section 484 is smaller than the inner diameter of the coil of the elastic member 44, and the cross-sectional diameter of the cylinder of the abutting portion 482 is larger than the inner diameter of the coil of the elastic member 44. The hemispherical portion of the abutment portion 482 abuts the contact member 46, and the sleeve portion 484 fits into the coil of the elastic member 44. Like the conductive terminal 20, since the contact surface of the abutting portion 482 is spherical, and due to the existence of the inclined surface of the contact member 46, even if the end surface of the elastic member 44 is the I flat end surface, the contact member 46 can still abut the post 48. Pushing down the tilt causes the sleeve 22 to make good contact with the base 262 of the contact element 26, thereby maintaining a good electrical connection between the electronic components connected by the conductive terminals 20 or between the printed circuit boards. It can be understood that the abutting elements abutting the contact elements 26, 46 are not limited to the spherical abutment balls 28 in the first embodiment and the abutment posts 48 in the second embodiment, and the contact elements 26, 46 The abutting contact faces are not limited to the spherical faces in the first and second embodiments, and may be other smooth convex or tapered faces to be inclined against the contact members 26, 46. The contact surface shapes of the contact elements 26, 46 and the abutting elements are mutually replaceable, i.e., the contact faces of the contact elements 26, 46 are said smooth convex or tapered faces, and the contact faces of the abutting elements are beveled. The contact faces of the contact elements 26, 46 and the abutting elements may be both beveled or smooth convex. Here, only the contact surfaces of the contact elements 26, 46 and the abutment elements are engaged so that the contact elements 26, 46 can be pushed obliquely against the abutment element. In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law. However, the above is only a preferred embodiment of the present invention.
