Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette accessories technology, and in particular to a solderless electronic cigarette connector. Background Technology

[0002] In the assembly and production of electronic cigarettes, the PCB board, as a core control component, needs to be electrically connected to the power supply module, atomization module, etc. through connectors.

[0003] Traditional electronic cigarette connectors are mostly fixed to the PCB board by soldering, and the soldering operation is mostly done manually. For example, in the patent application CN114223956A, a cartridge and electronic cigarette, the first electrical connector and the detection electrode are electrically connected through a first intermediate connector. The first intermediate connector is electrically connected to the first electrical connector (such as the PCB board of this application) by soldering. The detection electrode is located at the mouthpiece of the cartridge and is used to detect whether the user's lips are in contact with or close to the mouthpiece. However, manual soldering is prone to problems such as cold solder joints and missing solder joints, resulting in poor circuit contact and affecting the normal operation of the electronic cigarette. At the same time, whether it is manual or mechanical soldering, the soldering temperature and time must be controlled to avoid high temperature damage to the PCB board or surrounding components, making the process complicated.

[0004] In addition, if the connector or PCB board fails, the soldered structure is difficult to disassemble and replace, requiring the entire component to be replaced, which increases maintenance and labor costs. Utility Model Content

[0005] The purpose of this invention is to provide a solderless electronic cigarette connector that replaces the traditional soldering method with a plug-in structure, achieving a fast and stable connection with the PCB board, while simplifying the assembly process and reducing maintenance costs.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A solderless electronic cigarette connector for electrical connection to an internal PCB board of an electronic cigarette includes an L-shaped connector terminal that is electrically connected to the PCB board via an insertion method. The bottom of the L-shaped connector terminal has a flexible hook portion bent downwards, and a flexible connecting portion bent to one side. The PCB board has an opening through which the flexible hook portion passes, and a conductive portion that is electrically connected to the flexible connecting portion. The top of the flexible hook portion also extends to form an L-shaped abutment portion that abuts against the inner wall of the opening. The top of the L-shaped connector terminal has an inspection portion for detecting contact between human lips and the electronic cigarette cartridge.

[0008] Preferably, there are two elastic connecting parts, which are located at opposite ends of the elastic hook part.

[0009] Preferably, the elastic connection part has an overall "semi-circular" curved structure, with the arc surface facing the conductive part, and has elastic force.

[0010] Preferably, the elastic hook portion is "hook-shaped" and has an elastic force toward the opening side.

[0011] Preferably, the cross-section of the L-shaped connecting terminal is flat or circular.

[0012] Preferably, the inspection part is a conductive contact piece that can generate an electrical signal feedback through human contact.

[0013] Preferably, the L-shaped abutment portion has a horizontal abutment surface and a vertical abutment surface, the vertical abutment surface forming an elastic abutment with one side of the inner wall of the opening, and the horizontal abutment surface forming an elastic abutment with the bottom surface of the PCB board.

[0014] Compared with the prior art, the solderless electronic cigarette connector provided by this utility model has the following advantages:

[0015] This utility model achieves a quick and stable connection between the L-shaped connector and the PCB board by inserting the elastic hook and L-shaped abutment part into the opening of the PCB board, replacing the traditional soldering method. It also simplifies the assembly process and reduces maintenance and labor costs. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0023] like Figures 1-4 As shown, a solderless electronic cigarette connector is used for electrical connection of the internal PCB board 2 of an electronic cigarette. It includes an L-shaped connection terminal 1 that is electrically connected to the PCB board 2 by insertion. The L-shaped connection terminal 1 is integrally formed by stamping and bending processes, and the overall cross-section is flat, which is suitable for the internal space of a thin electronic cigarette.

[0024] Specifically, the bottom of the L-shaped connecting terminal 1 is bent downwards to form a "hook-shaped" elastic hook portion 11, and two elastic connecting portions 12 with a "semi-circular" bending structure are bent to one side at opposite ends of the elastic hook portion 11. The top of the L-shaped connecting terminal 1 extends to an inspection portion 14, which is a conductive contact piece that can generate an electrical signal feedback through human contact to realize the detection of contact recognition between human lips and electronic cigarette cartridges. The top of the elastic hook portion 11 also extends to an L-shaped abutment portion 13 that abuts against the inner wall of the opening 21. The L-shaped abutment portion 13 has a horizontal abutment surface 131 and a vertical abutment surface 132.

[0025] The PCB board 2 has an opening 21 for the elastic hook part 11 to pass through. The opening 21 is rectangular, and its diameter is slightly larger than the width of the elastic hook part 11 (difference of 0.2mm) to facilitate insertion. The vertical abutment surface 132 forms an elastic abutment with one side of the inner wall of the opening 21, and the horizontal abutment surface 131 forms an elastic abutment with the bottom surface of the PCB board 2. The side of the elastic hook part 11 facing the opening 21 has an elastic force, so that the vertical abutment surface 132 and the horizontal abutment surface 131 are firmly and elastically abutted with the inner wall of the opening 21 and the bottom surface of the PCB board 2, respectively, making the insertion tight and not easy to loosen, ensuring stable conductive connection.

[0026] The PCB board 2 also has a conductive part 22 that is electrically connected to the elastic connection part 12. The arc surface of the elastic connection part 12 faces the conductive part 22 and has a certain elastic force on the conductive part 22, so that the elastic connection part 12 is firmly and elastically abutted against the conductive part 22, thereby achieving the stability of electrical conduction and further ensuring conductivity.

[0027] Assembly process:

[0028] like Figure 3 As shown, align the elastic hook 11 of the L-shaped connector 1 with the opening 21 of the PCB board 2, and press the L-shaped connector 1 downwards. The elastic hook 11 is deformed by the pressure of the inner wall of the opening 21, and returns to its original shape after passing through the opening 21; at this time, as Figure 4As shown in the enlarged view at point A, the horizontal contact surface 131 of the L-shaped contact part 13 is attached to the bottom surface of the PCB board 2, and the vertical contact surface 132 is attached to one side of the inner wall of the opening 21, forming a tight elastic contact, thus completing the assembly of the L-shaped connecting terminal 1 and the PCB board 2.

[0029] Meanwhile, the semi-circular arc surface of the elastic connection part 12, under its own elastic force, fits tightly with the conductive part 22 of the PCB board 2, forming a stable electrical connection circuit to realize signal and current transmission.

[0030] If the L-shaped connector 1 or PCB board 2 needs to be replaced, simply press the hook-shaped end of the elastic hook part 11 lightly to deform it into the opening 21, and at the same time pull the L-shaped connector 1 upward to disengage the elastic hook part 11 from the opening 21 to complete the disassembly; after replacing the new part, repeat the above assembly steps to restore its use.

[0031] Working principle: The assembled components are installed into the e-cigarette shell, and the inspection part 14 (conductive contact piece) is aligned with the contact area of ​​the e-cigarette cartridge. The e-cigarette shell is made of metal and is electrically connected to the ground terminal of the PCB board. When the human lips touch the e-cigarette cartridge, the contact piece forms a conductive circuit through the human body and the e-cigarette shell (grounded), generating an electrical signal and transmitting it to the PCB board 2. After receiving the signal, the PCB board 2 starts the atomization module to realize the "contact start" function.

[0032] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
