Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of anti-tin creeping connectors, in particular to a connector component with an anti-tin creeping function applied to electronic cigarettes. Background Art
[0002] Since the Pogopin rivet mouth is exposed to the outside facing upward, some Pogopin connectors used in electronic cigarettes are prone to dust accumulation and the influence of smoke oil at the contact point of the needle and needle tube when they are in a smoke and smoke oil environment for a long time. At this time, conventional hollow, beveled, mushroom head and other structures are prone to contact problems, which is reflected in the product that it is easy to produce no smoke or intermittent smoke. In the prior art, common electronic cigarette Pogopin connectors usually have the following three structures:
[0003] The first type is the coaxial plus welding wire hole type. Due to the limitation of space size, the welding wire hole is too small to meet the application of large current, that is, the product application is limited;
[0004] The second is the common coaxial type, where the wire is manually soldered at the tail of the Pogopin. Since the welding diameter is circular, the welding is the most difficult, and poor soldering is likely to occur, resulting in the inability of the Pogopin to retract and connect;
[0005] The third type is the conventional coaxial type with a tail ring. Although the tail ring can prevent solder creep during manual soldering and cause product defects, the tail ring is prone to product displacement and failure due to thermal expansion and contraction.
[0006] Therefore, in the prior art, the Pogopin connector used in the electronic cigarette has the problem of tin creeping when the welding wire is welded. In addition, in some Pogopin connectors with anti-tin creeping tail ring settings, when the tail ring welding wire is at a high temperature, the tail ring is easily heated and expanded, resulting in poor welding effect.
[0007] Therefore, we propose a connector assembly with anti-tin creeping function for electronic cigarettes to solve the above-mentioned technical problems. Utility Model Content
[0008] In view of this, the main purpose of the present invention is to provide a connector assembly with anti-tin creeping function for electronic cigarettes, which is used to solve the above problems.
[0009] To achieve the above purpose, the utility model adopts the following technical solution: it includes a needle tube, a needle slidably arranged inside the needle tube, and a spring sleeved on the outside of the needle and located inside the needle tube, and the tail end of the needle tube is provided with an anti-climbing tin component.
[0010] As a preferred solution, the anti-tin creeping assembly includes a tail ring, and the tail ring is arranged at the tail end of the needle tube.
[0011] As a preferred solution, the cross-section of the tail ring is T-shaped, and a circular through hole is opened in the middle of the tail ring.
[0012] As a preferred solution, the tail ring is slidably fitted and connected to the tail end of the needle through a circular through hole opened in the middle.
[0013] As a preferred solution, a chip removal groove is provided on the inner side of one end of the tail ring close to the needle tube.
[0014] As a preferred solution, the length of the tail ring is greater than the telescopic length of the needle inside the needle tube.
[0015] As a preferred solution, the upper end of the needle tube has a rivet opening that is recessed and extends inward, and the needle tube restricts the needle from escaping from the interior of the needle tube through the rivet opening.
[0016] Compared with the prior art, the utility model has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that it mainly has the following advantages:
[0017] Through the superposition of the tail ring and the chip removal groove, the device effectively solves the shortcomings of existing products such as small charging current, easy tin creeping, and easy thermal expansion and displacement failure without increasing product costs or affecting assembly efficiency, and has strong practicality.

[0026] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below with reference to the accompanying drawings and implementation examples. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0027] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.
[0028] See also Figures 4 to 6 The embodiment of the utility model provides a connector assembly with anti-tin creeping function for electronic cigarettes, including a needle tube 1, a needle 2 slidably arranged inside the needle tube 1, and a spring 4 sleeved on the outside of the needle 2 and located inside the needle tube 1. The upper end of the needle tube 1 has a rivet opening concavely extending inward, and the needle tube 1 limits the needle 2 from leaving the inside of the needle tube 1 through the rivet opening. The needle 2 is movably arranged inside the needle tube 1, and is limited by the rivet opening arranged on the needle tube 1, so that the needle 2 can only move up and down inside the needle tube 1. The tail end of the needle tube 1 is provided with an anti-tin creeping assembly, and the anti-tin creeping assembly includes a tail ring 3, which is arranged at the tail end of the needle tube 1, and the length of the tail ring 3 is greater than the telescopic activity length of the needle 2 inside the needle tube 1, and the cross-section of the tail ring 3 is T-shaped, and a circular through hole is opened in the middle of the tail ring 3;
[0029] Through such an arrangement, a welding wire hole is formed between the tail ring 3 and the needle tube 1, so that soldering can be performed through the welding wire hole. Compared with the existing three common structures, the characteristic of tin climbing during high-temperature wire welding can be utilized to allow the solder to climb all over the outside of the tail ring 3 to complete the soldering process, and the welding wire hole formed inside can be used to weld the wires that need to be soldered, and during the wire welding process, the solder can prevent the needle head 2 and the tail ring 3 from being fixed together, and the movement of the needle head 2 after the soldering is completed can be reduced, thereby improving the product's molding rate and subsequent use effects, and at the same time increasing the product's service life. The design of the welding wire hole reduces the processing difficulty during wire welding, improves the stability of the connection between the wire and the needle head 2 after the wire welding process, and avoids shaking, displacement failure, and loose fixation when the overall structure shakes under high-temperature conditions of soldering.
[0030] See also Figures 4 to 6 The tail ring 3 is slidably fitted and connected with the tail end of the needle 2 through a circular through hole opened in the middle. Through this arrangement, the needle 2 can be limited and the up and down movement of the needle 2 is smoother, reducing shaking during movement.
[0031] See also Figure 5 A chip discharge groove 5 is provided on the inner side of one end of the tail ring 3 close to the needle tube 1. The chip discharge groove 5 is used for discharging the electronic cigarette oil during the use of the electronic cigarette to avoid blockage.
[0032] In summary, the device, through the combined effect of the tail ring 3 and the chip groove 5, effectively solves the shortcomings of existing products such as small charging current, easy tin creeping, and easy thermal expansion and displacement failure without increasing product costs and without affecting assembly efficiency, and is highly practical.
[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the principles of the present invention should be included in the protection scope of the present invention.
