Abstract
Description
Technical Field
[0001] This patent relates to the field of electrical equipment technology, specifically to a conductive spring and a conductive connection structure. Background Technology
[0002] Atomizers are common consumer electronics products. They typically contain a vaping sensor that records the number of inhalations during operation. This sensor requires power to function, necessitating a spring-loaded contact on the atomizer's circuit board to engage with it and supply power. Currently, commonly used springs are simple sheet-like structures, usually soldered to the circuit board. This method results in unstable fixation, a tendency for the spring to detach, and a lack of restraint. Consequently, the spring is prone to inelastic deformation under stress and cannot return to its original shape, leading to damage and ultimately rendering the entire atomizer unusable. Utility Model Content
[0003] To solve the above-mentioned technical problems, this patent discloses a conductive spring and a conductive connection structure.
[0004] The conductive spring includes a spring mounting mechanism, a spring limiting mechanism, a spring elastic contact mechanism, and a connecting body. The spring mounting mechanism, spring limiting mechanism, and spring elastic contact mechanism are all disposed on the connecting body. The spring limiting mechanism limits the elastic movement range of the spring elastic contact mechanism. The spring mounting mechanism includes a plug-in part and a support part, both of which are disposed on the connecting body. The plug-in part is used for plugging and fixing the spring, and the support part is used for supporting the spring.
[0005] The conductive connection structure includes a conductive spring, a conductive connecting piece, a first circuit board, and a second circuit board. The conductive spring is the aforementioned conductive spring. The conductive spring is inserted into the first circuit board through a plug-in part, and the conductive spring is supported and mounted on the first circuit board through a support part. The conductive connecting piece is disposed on the second circuit board, and the conductive spring and the conductive connecting piece abut against each other to achieve electrical connection.

[0019] See Figures 1-3 A conductive spring 1 is used for conductive connections in electronic products. The conductive spring 1 includes a spring mounting mechanism 11, a spring limiting mechanism 12, a spring elastic contact mechanism 13, and a connecting body 14. The connecting body 14 is the main structure of the conductive spring. The spring mounting mechanism 11, the spring limiting mechanism 12, and the spring elastic contact mechanism 13 are all disposed on the connecting body 14, connecting them into a whole to form the conductive spring 1. The spring mounting mechanism 11 is used to mount the conductive spring 1 onto structures such as circuit boards. The spring mounting mechanism 11 includes a plug-in part 111 and a support part 112, both disposed on the connecting body 14. The plug-in part 111 is used for positioning and plugging in the spring, and the support part 112 is used for supporting the spring. When the conductive spring 1 is used in the atomizer, it can be inserted and fixed onto the first circuit board 3 via the insertion part 111, and supported on the solder pads of the first circuit board 3 by the support part 112, so that the conductive spring 1 is stably fixed on the circuit board and is not easy to fall off. The spring limiting mechanism 12 limits the elastic movement range of the spring elastic contact mechanism 13, so that the elastic contact mechanism 13 of the conductive spring moves within the elastic limit range and will not undergo inelastic deformation and be unable to return to its original shape, ensuring the long-term stable use of the conductive spring, ultimately ensuring the reliability of the atomizer and extending its service life.
[0020] See Figure 1 and Figure 2The insertion part 111 is an outwardly extending insertion pin on the connector 14. When the conductive spring 1 is installed on the first circuit board 3, the insertion part 111 is inserted into the slot provided on the first circuit board 3, thereby achieving the positioning of the conductive spring 1. It is preferable to provide two sets of insertion parts 111. By positioning and fixing the conductive spring 1 on the first circuit board 3 with two sets of insertion parts 111, the stability of fixing the conductive spring 1 on the first circuit board 3 can be improved. In addition, the insertion part 111 can be further glued to the slot of the first circuit board 3 by adhesive, which further improves the stability of the conductive spring 1 installed on the first circuit board 3 and prevents the conductive spring 1 from falling off the first circuit board 3. The support part 112 is a support piece formed by bending on the connector 14. When the conductive spring 1 is installed on the first circuit board 3, the support part 112 is fixed to the pad of the first circuit board 3 by soldering, which can mechanically fix the conductive spring 1 on the first circuit board 3, and at the same time realize the electrical connection between the conductive spring 1 and the circuit on the first circuit board 3.
[0021] See Figure 1 and Figure 2 The spring-loaded limiting mechanism 12 includes two limiting frames 121 and one limiting rod 122. The connecting body 14 is a quadrilateral sheet structure. When the connecting body 14 is placed vertically, it has four sides: top, bottom, left, and right. The two limiting frames are arranged on the left and right opposite sides of the connecting body. The spring-loaded elastic contact mechanism 13 and the mounting mechanism 11 are respectively arranged on the top and bottom opposite sides of the connecting body 14. The two limiting frames are located between the spring-loaded elastic contact mechanism and the mounting mechanism. The limiting rod 122 is located at the end of the spring-loaded elastic contact mechanism 13. The limiting rod 122 is limited and installed within the limiting frame 121, so that the limiting rod 122 can only move within the limiting frame 121. The spring-loaded elastic contact mechanism 13 can only move within a certain range. The size of the range of motion of the limiting rod 122 within the limiting frame 121 is set according to the size of the elastic range of motion of the spring-loaded elastic contact mechanism 13. The spring-loaded elastic contact mechanism 13 of the conductive spring moves within the elastic limit range and will not undergo inelastic deformation and be unable to return to its original shape. Preferably, two sets of limiting frames 121 are provided, and the two sets of limiting frames 121 are arranged on the left and right opposite sides of the connecting body 14, with the two ends of the limiting rod 122 respectively limited within one set of limiting frames 121. The two sets of limiting frames 121 can better limit the range of motion of the limiting rod 122, thereby better limiting the range of motion of the elastic contact mechanism 13 within the elastic limit range.
[0022] See Figures 1-3The spring-loaded elastic contact mechanism 13 is a semi-enclosed frame structure extending from the connecting body 14. The semi-enclosed frame structure has included angles on adjacent sides, at least one of which is an acute angle. Setting one corner of the semi-enclosed frame structure as an acute angle allows the spring-loaded elastic contact mechanism 13 to make more complete contact with another component to be electrically connected. Figure 3 In the semi-enclosed frame structure, the included angles α and β formed by the adjacent two sides are as follows: included angle α is an acute angle, and the vertex outside included angle α can make more full contact with another component to be electrically connected, thereby improving the reliability of the conductive connection of the conductive spring 1.
[0023] See Figure 1 and 2 The spring-loaded elastic contact mechanism 13 is a sheet-like structure with a protruding rib 131 in the middle. The protruding rib 131 in the middle of the spring-loaded elastic contact mechanism 13 increases its strength, preventing inelastic deformation, and also ensures sufficient contact between the spring-loaded elastic contact mechanism 13 and another component to be electrically connected, thus improving the reliability of the electrical connection of the conductive spring 1.
[0024] See Figure 1 and 2 The spring plate mounting mechanism 11, the spring plate limiting mechanism 12, the spring plate elastic contact mechanism 13, and the connecting body 14 are integrally stamped structures. They are formed by stamping metal sheets. During stamping, the outer shapes of the spring plate mounting mechanism 11, the spring plate limiting mechanism 12, and the spring plate elastic contact mechanism 13 are first punched on a whole sheet of metal, and then the spring plate mounting mechanism 11, the spring plate limiting mechanism 12, and the spring plate elastic contact mechanism 13 are formed by stamping and bending.
[0025] See Figures 1-7 This embodiment also discloses a conductive connection structure for electrical connection between an atomizer inhalation sensor and a circuit board. The conductive connection structure includes a conductive spring 1, a conductive connecting piece 2, a first circuit board 3, and a second circuit board 4. The conductive spring 1 is the aforementioned conductive spring, which is inserted into the first circuit board 3 via a plug-in portion 111. The conductive spring 1 is supported by a support portion 112 and soldered to the pads of the first circuit board 3, thereby fixing and electrically connecting the conductive spring 1 to the first circuit board 3. The conductive connecting piece 2 is soldered and fixedly disposed on the second circuit board 4, and the conductive spring 1 abuts against the conductive connecting piece 2 to achieve electrical connection.
[0026] See Figures 4-7The conductive connection structure also includes a first bracket 5 and a second bracket 6. The first circuit board 3 is disposed on the first bracket 5, and the second circuit board 4 is disposed on the second bracket 6. The first bracket 5 and the second bracket 6 are detachable and installable. When the first bracket 5 and the second bracket 6 are installed together, the conductive spring 1 and the conductive connecting piece 2 abut against each other to achieve electrical connection. When the first bracket 5 and the second bracket 6 are separated, the conductive spring 1 and the conductive connecting piece 2 separate to achieve electrical disconnection.
[0027] See Figures 4-7 As a detachable installation method for the first bracket 5 and the second bracket 6, one of the first bracket and the second bracket is provided with a slot, and the other of the first bracket and the second bracket is provided with a plug. In this embodiment, the first bracket 5 is provided with a slot 51, and the second bracket 6 is provided with a plug 61. The plug 61 is inserted into the slot 51. When the first bracket 5 is inserted into the second bracket 6, the conductive spring 1 and the conductive connecting piece 2 abut against each other, realizing electrical conductivity between the conductive spring 1 and the conductive connecting piece 2. The size, shape, and position of the plug 61 are consistent with the size, shape, and position of the slot 51, so that the plug 61 can be inserted into the slot 51 exactly. When the plug 61 is inserted into the slot 51, the conductive spring 1 and the conductive connecting piece 2 abut against each other and are electrically conductive; when the plug 61 is pulled out of the slot 51, the conductive spring 1 and the conductive connecting piece 2 separate and are electrically disconnected. While the first bracket 5 and the second bracket 6 are plugged in or separated, the conductive spring 1 and the conductive connecting piece 2 are simultaneously electrically connected or electrically disconnected, eliminating the need for additional electrical connection steps and facilitating the production and assembly of electronic products.
