Description

Technical Field

[0001] The utility model relates to the technical field of charging spring pieces, and specifically relates to an inserted SMT three-pin angle positioning patch vertical charging spring piece. Background Art

[0002] In the current field of electronic device charging, the charging spring piece, as a key component connecting the power supply and the battery, its stability and reliability directly affect the charging efficiency and usage safety. However, the existing charging spring piece designs often only have one pin angle (for example, the previously applied two-position contact U-shaped side-connected conductive multi-functional spring piece, with the publication number CN218867436U). This design has significant limitations when welding and fixing with the PCB board. Specifically, due to the limited number of pin angles, it is difficult to ensure a firm connection between the spring piece and the PCB board during the welding process, easily leading to unstable welding and then the phenomenon of spring piece deflection. When the charging spring piece deflects, uneven force will occur when it contacts the charging terminal, which will not only affect the charging efficiency but also may cause safety hazards such as overheating and short circuit due to poor contact. Therefore, we propose an inserted SMT three-pin angle positioning patch vertical charging spring piece. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides an inserted SMT three-pin angle positioning patch vertical charging spring piece, which solves the problems raised in the above background art.

[0004] To achieve the above purposes, the utility model is realized through the following technical solutions: An inserted SMT three-pin angle positioning patch vertical charging spring piece includes a main body support plate one and a main body support plate two. A force arm is commonly connected between the main body support plate one and the main body support plate two. The bottoms of the main body support plate one, the main body support plate two, and the force arm are bent correspondingly to form a pin angle one, a pin angle two, and a pin angle three, and the pin angle one, the pin angle two, and the pin angle three are distributed in a triangle.

[0005] Further, a reinforcing rib is arranged inside the force arm, and the support strength of the force arm can be increased through the reinforcing rib.

[0006] Further, the top end of the force arm is bent multiple times to form a first elastic arm and a second elastic arm, and the force arm, the pin angle three, the first elastic arm, and the second elastic arm are an integral body.

[0007] Further, the first elastic arm is set in an "S" shape, and the second elastic arm is set in a "U" shape.

[0008] Further, the second elastic arm is bent to tilt upward as a whole, and a contact point is arranged at the highest point of the tilt.

[0009] Further, the angle at which the second elastic arm tilts obliquely upward is 45°.

[0010] Further, a constraint portion is formed after the top end of the first main body support plate is bent. The end of the constraint portion facing away from the first main body support plate extends towards the second main body support plate and forms a buckle after being bent again. The buckle is engaged with the top end of the second main body support plate.

[0011] Further, the bending angles between the first main body support plate and the third insertion angle, between the second main body support plate and the first insertion angle, between the second main body support plate and the second insertion angle, between the first main body support plate and the constraint portion, and between the constraint portion and the buckle are all 90°.

[0012] The utility model provides an insert type SMT three-insertion-angle positioning patch vertical charging elastic sheet. Compared with the prior art, it has the following beneficial effects:

[0013] The insert type SMT three-insertion-angle positioning patch vertical charging elastic sheet has three insertion angles, and the three insertion angles are integrally distributed in a triangular shape, forming a stable triangular support structure. This structure is the most stable form geometrically, which can greatly enhance the stability of the charging elastic sheet when welding with the PCB board, effectively prevent the yaw phenomenon during the welding process, and ensure that the elastic sheet always maintains the correct position during use.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1-6 The utility model provides a technical solution: an inserted SMT three-angle positioning patch vertical charging spring, composed of a main support plate 1, a main support plate 2, and a force arm 3, wherein the main support plate 1, the main support plate 2, and the force arm 3 are subjected to a first stamping and bending process, and the overall structure is a "U"-shaped structure, and the main support plate 1, the main support plate 2, and the bottom end of the force arm 3 are subjected to a second stamping and bending process to form a plug angle 1 4, a plug angle 2 5, and a plug angle 3 6, and when the charging spring is connected to the PCB board 13, the plug angle 1 4, the plug angle 5, and the plug angle 6 are formed. The second corner 5 and the third corner 6 are both welded in the holes reserved in the PCB board 13, wherein the second corner 5 and the third corner 6 are oppositely distributed, and the first corner 4, the second corner 5 and the third corner 6 are triangularly distributed, which can be an equilateral triangle distribution or an isosceles triangle distribution. Compared with the structure in the prior art in which only one corner is welded and fixed to the PCB board 13, the structure with three corners and triangular distribution makes the charging spring piece not deflect in the SMT patch after being welded to the PCB board 13, and the force is evenly distributed when in contact, and the contact is more stable;

[0023] In addition, in order to improve the supporting strength of the force arm 3, a reinforcing rib 7 is arranged inside the force arm 3, so that the strength of the entire charging spring will be higher. In order to enable the charging spring to have a higher elastic ability after contacting the charger terminal 14, the top of the force arm 3 is bent multiple times to form a first elastic arm 8 and a second elastic arm 9, wherein the first elastic arm 8 is set to an "S" shape, and the second elastic arm 9 is set to a "U" shape. After bending, the second elastic arm 9 is tilted upward as a whole, and the tilting angle is 45°. A contact 10 is set at the highest point of the tilting, and the contact 10 can contact the charger terminal 14.

[0024] Finally, in order to improve the integrity of the charging spring piece, the top of the main support plate 1 is bent to form a constraint portion 11, and the top of the constraint portion 11 is set to a plane. In this way, when the charging spring piece is welded to the PCB board 13, the external manipulator can more easily adsorb the charging spring piece. The end of the constraint portion 11 away from the main support plate 1 extends toward the main support plate 2, and is bent again to form a buckle 12. The buckle 12 is engaged with the top of the main support plate 2. After engagement, the tops of the main support plate 1 and the main support plate 2 will constrain each other, and the integrity will be stronger.

[0025] It should be noted that the bending angles between the main support plate 1 and the insertion angle 3, the main support plate 2 and the insertion angle 1, the main support plate 2 and the insertion angle 2, the main support plate 1 and the constraint part 11, and the constraint part 11 and the buckle 12 are all 90°. A bending angle of 90° means that the connection between each component is more stable. In mechanics, a right-angle connection can effectively disperse and resist forces from all directions, reducing the risk of structural deformation and damage. This design makes the entire support structure more stable when bearing weight and less likely to tilt or collapse.
