The spring connector is widely used in electronic products such as mobile phones, and the main connection mode is to arrange a convex hull at the contact part of the spring and the PAD to realize electric connection. The different contact forms of the convex hull and the PAD can influence the quality of electric signal transmission and the contact reliability, and the point contact is most beneficial to high-frequency signal transmission. However, in the related art, a point contact effect is obtained by adopting a mode of contacting the circular convex hull with a plane, and in the matching process of the circular convex hull of the elastic sheet and the PAD, the technical problems of small contact range and insufficient stability exist.
The present disclosure provides a dome connector. Fig. 1 is a schematic perspective view of a spring connector according to an exemplary embodiment of the present disclosure, and fig. 2 is a schematic perspective view of a spring contact according to an exemplary embodiment of the present disclosure, where, as shown in fig. 1 and fig. 2, the spring connector 1 includes a spring 11 and a spring contact 12. The spring plate 11 includes an abutment structure 111 and a first protrusion 112 disposed on a surface of the abutment structure 111, and the first protrusion 112 includes a first linear abutment 1121. The spring contact 12 includes a main structure 121 and a second protrusion 122 disposed on the main structure 121, the second protrusion 122 includes a second linear abutting portion 1221, and the first linear abutting portion 1121 and the second linear abutting portion 1221 intersect during a dynamic matching process of the spring 11 and the spring contact 12 and form a point contact fit.
Since the above-mentioned elastic sheet 11 and the elastic sheet contact 12 obtain the point contact effect through the intersection of the first linear abutting portion 1121 on the first protrusion 112 and the second linear abutting portion 1221 on the second protrusion 122, the first linear abutting portion 1121 and the second linear abutting portion 1221 form a longer contact path by using their own linear structures in the dynamic matching of the elastic sheet 11 and the elastic sheet 11 connection, and are continuously in a stable point contact matching state, thereby improving the reliability of conductive connection and the transmission quality and stability of high-frequency signals.
In some embodiments, as shown in fig. 2, the first protrusion 112 includes a bar-shaped structure disposed on a surface of the abutment structure 111, and the second protrusion 122 includes a bar-shaped structure disposed on a surface of the main body structure 121. The strip-shaped structure not only can provide a structural foundation for the first linear abutting portion 1121 and the second linear abutting portion 1221, but also can reduce the space occupation of the first protrusion 112 on the spring plate 11 and the space occupation of the second protrusion 122 on the spring plate contact 12, and simplify the structural arrangement of the spring plate connector 1.
In the above-described embodiment, the first line-type abutment portion 1121 may be a line structure provided along the length direction of the bar-shaped structure, and the second line-type abutment portion 1221 may be a line structure provided along the length direction of the bar-shaped structure. The main structure 121 may be a plate-like structure, and the direction of relative movement of the spring piece 11 and the spring piece contact 12 may be the same as the longitudinal direction of the plate-like structure, and the bar-like structure as the second protrusion 122 may be disposed obliquely with respect to the longitudinal direction of the plate-like structure, so that the second linear abutting portion 1221 and the first linear abutting portion 1121 may form an intersecting positional relationship, and thus a point-contact connection effect may be obtained. The dashed line in fig. 2 may represent the longitudinal direction of the plate-like structure, and the dashed line may represent the extending direction of the bar-like structure of the second protrusion 122, and the bar-like structure as the second protrusion 122 has an inclination angle α with respect to the longitudinal direction of the plate-like structure.
The longitudinal direction of the abutment structure 111 may be parallel to a normal plane parallel to the longitudinal direction of the plate-like structure, and the stripe-like structure as the first protrusion 112 may extend along the longitudinal direction of the abutment structure 111 on the surface of the abutment structure 111. When the surface of the abutting structure 111 is a plane, the first protrusions 112 form a linear bar-shaped structure parallel to the longitudinal direction of the plate-shaped structure. When the surface of the abutting structure 111 is a curved surface, the first protrusion 112 forms a curved strip-shaped structure.
In the above embodiment, the second protrusion 122 may extend from one end of the main body structure 121 to the other end of the main body structure 121 to increase the size of the second protrusion 122 on the main body structure 121. The second protrusion 122 may extend from one end of the main body structure 121 to the other end in the length direction, or may extend from one end of the main body structure 121 to the other end in the width direction, and may be selected according to the arrangement scheme of the second protrusion 122 and the second linear abutment 1221 thereon, which is not limited in this disclosure.
In some embodiments, the first protrusion 112 and/or the second protrusion 122 comprise an arcuate surface, the first linear abutment 1121 comprises a straight line and/or a curved line disposed on the arcuate surface of the first protrusion 112, and the second linear abutment 1221 comprises a straight line and/or a curved line disposed on the arcuate surface of the second protrusion 122. The shape and positional flexibility of the first and second linear abutments 1121 and 1221 are increased by the arcuate surfaces of the first and/or second protrusions 112 and 122, and point contact can be made even if the spring pieces 11 and 12 are positionally offset during assembly.
For example, when the first protrusion 112 and the second protrusion 122 include semi-circular arc surfaces, during the abutting process of the spring 11 and the spring contact 12, a straight line formed by the first protrusion 112 protruding from the highest portion of the abutting structure 111 intersects with a straight line formed by the second protrusion 122 protruding from the highest portion of the main body structure 121 and is in point contact fit.
In some embodiments, as shown in fig. 3 and 4, the surface of the abutment structure 111 includes a curved surface, and at least a portion of the first protrusion 112 is disposed on the curved surface. The surface of the abutting structure 111 comprises a bending curved surface, so that an elastic abutting force is obtained in the elastic abutting process of the elastic sheet 11 and the elastic sheet contact 12, and the connection reliability of the elastic sheet 11 and the elastic sheet contact 12 is ensured.
In some embodiments, the spring 11 includes a base 113 and a deformation portion 114 connected to the base 113, where the deformation portion 114 is bent relative to the base 113, and one end of the abutting structure 111 is connected to the deformation portion 114. The deformation of the deformation portion 114 can drive the position of the spring 11 relative to the spring contact 12 to change, and simultaneously provide a force for the contact between the spring 11 and the spring contact 12.
The elastic sheet 11 may further include a limiting portion 115 connected to the other end of the abutting structure 111, an extending wall 116 is disposed on the base 113, and a limiting groove 1161 is disposed on the extending wall 116, where the limiting portion 115 is assembled in the limiting groove 1161, so as to limit a limiting position of the elastic sheet 11 in a dynamic matching process of the elastic sheet 11 and the elastic sheet contact 12, and avoid a failure problem caused by excessive deformation of the elastic sheet 11 in the abutting process. For example, during the abutting process of the spring 11 and the spring contact 12, the deformation portion 114 bends to provide an abutting force for the abutting structure 111 of the spring 11, and the limiting portion 115 moves in the limiting groove 1161 along with the abutting structure 111, and abuts against the bottom of the limiting groove 1161 when moving to the limiting position, so as to limit the movement of the abutting structure 111. When the spring 11 is separated from the spring contact 12, the limiting portion 115 abuts against the top of the limiting groove 1161, so that the abutting structure 111 of the spring 11 is restored to the initial position.
The present disclosure further provides an electronic device, which includes a first functional component, a second functional component, and the above-mentioned spring connector 1, where the spring 11 is assembled to the first functional component, the spring contact 12 is assembled to the second functional component, and the first protrusion 112 abuts against the second protrusion 122, so that the first functional component and the second functional component are electrically connected.
Because the elastic sheet 11 and the elastic sheet contact piece 12 obtain the point contact effect through the intersection of the first linear abutting part 1121 on the first protrusion 112 and the second linear abutting part 1221 on the second protrusion 122, the first linear abutting part 1121 and the second linear abutting part 1221 form a longer contact path by utilizing the linear structure of the elastic sheet 11 and the elastic sheet 11 connecting piece in dynamic matching, and are continuously in a stable point contact matching state, so that the reliability of conductive connection between two functional components of the electronic equipment and the transmission quality and stability of high-frequency signals are improved.
In the above embodiment, the first functional component and the second functional component include one of a main board, a center antenna, a motor, and a speaker. For example, the first functional component may be a main board, the second functional component may be a speaker, the spring 11 may be disposed on the main board and electrically connected to a circuit on the main board, the spring 11 connector may be disposed on the speaker, during a connection process between the speaker and the main board, the spring 11 is matched with the spring 11 connector, and the first linear abutting portion 1121 of the first protrusion 112 and the second linear abutting portion 1221 of the second protrusion 122 intersect and form an electrical contact.
