Detailed Description
In order to facilitate understanding of the present invention, the present invention will be described in more detail with reference to the accompanying drawings and embodiments.
The embodiment of the utility model provides a spring conductive pin, can be used for realizing the conductive contact of two electrical parts, its structure is seen in fig. 2 to 4, including a barrel 10, and part hold in barrel 10 and can be along the telescopic gliding electrical contact 20 of barrel 10 axial direction; the inside of the barrel 10 is also provided with a coil spring 30 for providing an elastic force in the telescopic sliding of the electrical contact 20.
In the above preliminary structure, the conductive path of the spring conductive pin is mainly formed by the cylinder 10 and the electrical contact 20. Compared with the structure of the existing pogo pin, the difference of the above pogo pin lies in the combination manner of the electrical contact 20 and the coil spring 30, which can be seen in fig. 3.
The cylinder 10 includes a base 11 and a cylindrical portion 12 extending from one surface of the base 11, and a conductive connecting portion 13 is provided on the other surface of the base 11 opposite to the cylindrical portion 12. Wherein the content of the first and second substances,
the conductive connection portion 13 is used for the function of conductive connection with the electrical parts, and is represented by a commonly used cylindrical pin shape in fig. 2 and 3, which can facilitate the connection manner such as plugging, welding, etc., and in other embodiments, it can be designed to be suitable for the shape of the specific electrical parts.
The cylindrical portion 12 has a first end 121 and a second end 122 opposite to each other in the axial direction, the second end 122 is connected to the base portion 11, and the first end 121 is a closed end, thereby forming an inner closed space. Meanwhile, in order to facilitate the installation and elastic connection of the electrical contacts 20, the first end 121 is provided with holes through which the electrical contacts 20 penetrate to the outside (the pin holes are filled with the electrical contacts 20 in fig. 3, and no separate numeral indicates).
The cylindrical body 10 itself constitutes a conductive portion of an electrical connection path, and is formed of a conductive material in practice. Meanwhile, the base part 11 and the cylindrical part 12 are directly fixedly mounted inside the electronic product (such as a circuit board), so that the idea that high heat generation quantity after conduction generates high-temperature damage to other parts is avoided; in a more preferable mode, the cylinder 10 is made of a conductive material with low resistivity, such as a metal material, e.g., copper, silver, gold, etc.; on the other hand, there is a great possibility that the surface of the cylinder 10 may contact other parts during assembly and use, the conductive connection of the outer surface of the cylinder may be interfered by other parts, and the surface may be coated with an insulating layer, such as glass glaze.
Further, the electrical contact 20 includes a slide holder 21 accommodated in the cylindrical portion 12, the slide holder 21 being adapted to the sectional shape of the cylindrical portion 12, and the peripheral side wall of the slide holder 21 being in abutting contact with the inner wall of the cylindrical portion 12 after mounting, whereby electrical conduction can be established while also being able to slide reciprocally in the axial direction of the cylindrical portion 12. The sliding seat 21 has a first surface 211 opposite to the base 11, and a second surface 212 opposite to the first surface 211; the first surface 211 is provided with a connecting portion 23 for connecting with the coil spring 30, and the second surface 212 is provided with a contact portion 22 penetrating the first end 121 of the cylindrical portion 12.
Further, the coil spring 30 is disposed between the sliding seat 21 and the base seat 11 in the embodiment shown in the drawings, and one end thereof is connected to the base seat 11 and the other end thereof is connected to the sliding seat 21, so as to provide an elastic damping force during the extension and retraction of the electrical contact 20. The elastic damping force is applied to the electrical contact 20, so that the electrical contact can be biased toward the radial direction of the cylindrical part 12 during the sliding process along the axial direction of the cylindrical part 12, and the requirement of stable conduction in the sliding process of the electrical contact 20 is met. Since the outer diameter of the sliding seat 21 must be smaller than the inner diameter of the cylindrical portion 12 with a slight clearance in order to ensure smooth assembly and sliding of the electrical contact 20 within the cylindrical portion 12 in design and installation; these gaps cause rattling during sliding, which results in poor contact between the electrical contact 20 and the cylindrical portion 12. The side wall of the electrical contact 20 along the bias direction can always abut against the inner wall of the cylindrical part 12 when sliding through the bias of the elastic damping force, and the electrical contact 20 is prevented from shaking when sliding telescopically, so that the problem of poor contact is solved.
The purpose of biasing is achieved by means of elastic damping force and force applied to the electrical contact 20, and the two ways can be combined to achieve an optimal design. Wherein the content of the first and second substances,
one way is to mount the coil spring 30 in such a manner that it is inclined from the axial direction of the cylindrical portion 12 toward the radial direction, as shown in fig. 4 and 5, the direction in which the electrical contact 20 receives the elastic damping force does not coincide with the sliding direction, as shown by the force receiving direction F and the moving direction v in the force diagram of fig. 5; based on the mechanics knowledge, the electrical contact 20 tends to be biased as shown by the arrow r in fig. 5, so that the upper and lower side walls are kept in close and stable contact with the inner wall of the cylindrical portion 12, thereby eliminating the problem of poor contact.
In another embodiment, the point of application of the damping force to the cylindrical portion 12 by the coil spring 30 is provided at a position radially offset from the axis line of the force applied when the electrical contact 20 receives an external force. Specifically, after the electrical contact 20 abuts against an external component that needs to be electrically conductive, a stress diagram of the electrical contact 20 can be shown in fig. 6, where a stress part in fig. 6 is a connection part 23; the axial lead of the electrical contact 20 stressed when bearing external force is FOuter coverShown, the spring force is FBulletWhen the force-receiving portions to which the two forces are applied by the electrical contact 20 are biased, a bias tendency in the moving direction occurs naturally, as indicated by an arrow r in fig. 6, so that the upper and lower side walls are held in close and stable contact with the inner wall of the cylindrical portion 12, thereby eliminating the problem of poor contact.
Meanwhile, in combination with the above design of the position of the connecting portion 23, the coil spring 30 may also be designed in a corresponding structure, and in the preferred embodiment shown in fig. 3, the coil spring 30 is adopted, and the extending direction (the dotted line a in fig. 3) of the coil spring 30 and the axial direction (the dotted line B in fig. 3) of the cylindrical portion 12 have a certain inclination angle α; the force bias of the electrical contact 20 is formed by the direction of deformation of the coil spring 30 being at an angle to the direction of sliding of the electrical contact 20.
Further in the preferred embodiment of fig. 3, the diameter of the coil spring 30 is gradually reduced in a direction approaching the connecting portion 23 for ease of assembly and biasing effect. Meanwhile, the connection portion 23 is a boss extending from the first surface 211 of the sliding seat 21 toward the coil spring 30, and the boss is directly inserted into the central hole of the coil spring 30 during assembly, as shown in fig. 3 and 7.
The coil spring 30 having the above shape is a preferable component for providing the biasing elastic damping force, and an elastic member such as an elastic damper that can achieve the same function may be used instead in other embodiments.
With the spring conductive pin with the structure, after the helical spring 30 is compressed or extended, the electric contact 20 is pressed and attached to the inner wall of the cylindrical part 12 under the action of the bias elastic damping force, and the electric contact is pressed and attached more closely, so that stable and overlarge current can be ensured to be electrically connected, and the spring is not burnt. And the sliding is smooth without components and structures for generating blockage.
The embodiment of the present invention further provides an electronic cigarette including the above spring conductive pin, for example, the electronic cigarette is used in the electronic cigarette product shown in fig. 8, which includes an atomizer 100 and a power supply device 200 for supplying power to the atomizer 100, and the power supply device 200 is provided with the above spring conductive pin; in fig. 6, the contact portion 22 of the electrical contact 20 in the spring conductive pin is exposed on the surface of the power supply device 200, and the conductive connection portion 13 is connected to the main control circuit board inside the power supply device 200. So that when the atomizer 100 is assembled with the power supply device 200, the contact part 22 is contacted to conduct electricity, and the power supply device 200 supplies power to the atomizer 100.
Of course, in another modification, the spring conductive pin may be changed to be disposed on the atomizer 100, and the contact portion 22 of the spring conductive pin is exposed on the surface of the atomizer 100, and is contacted with the electrode on the power supply device 200 for conducting electricity during assembly, so that the power supply device 200 can supply power to the atomizer 100.
It should be noted that the preferred embodiments of the present invention are shown in the specification and the drawings, but not limited to the embodiments described in the specification, and further, it will be apparent to those skilled in the art that modifications and variations can be made in the above description and all such modifications and variations should fall within the scope of the appended claims.
