Description

Technical Field

[0001] This utility model relates to a spring needle, and more particularly to a conductive spring needle suitable for electronic tags, and further designs an electronic tag assembly including the conductive spring needle. Background Technology

[0002] In the field of electronic tags, existing technologies typically involve mounting electronic tags on corresponding wire troughs, with the connection to the trough establishing their power receiving structure, also known as the power supply structure. In practical applications, electronic tags need to be installed and removed according to different requirements. However, during installation and removal, electronic tags are inevitably subjected to non-perpendicular forces, such as lateral forces. Therefore, conductive springs are usually used to connect the electronic tag to the wire trough. However, existing conductive springs for electronic tags have two drawbacks: firstly, the lack of a positioning structure hinders rapid soldering during actual production; secondly, after soldering, insufficient solder or excessive deformation of the spring can cause the solder joint to lift, leading to unstable connections and affecting the normal operation of the electronic tag and the reliability and stability of the product. Summary of the Invention

[0003] The technical problem this invention aims to solve is to provide a conductive spring pin suitable for electronic tags. The design optimizes the structure to achieve welding positioning, increases the deformation that the conductive spring pin can withstand, and reduces the stress at the welding position, thereby improving product manufacturing efficiency and stability. Furthermore, this invention provides an electronic tag assembly including this conductive spring pin.

[0019] The preferred embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0020] like Figures 1 to 10 As shown, this embodiment provides a conductive spring needle, including: a welding part 1, a positioning part 2 and a deformation part 3. The welding part 1 and the deformation part 3 are respectively disposed at the left and right ends of the conductive spring needle, and the welding part 1 is elastically connected to the deformation part 3 through the positioning part 2.

[0021] In this embodiment, the welding part 1 refers to a welding structure used to fix and weld to the PCB circuit board 8, which can be a welding pillar or a welding pad, etc. The positioning part 2 refers to a positioning structure disposed between the welding part 1 and the deformation part 3. This positioning part 2 adopts a positioning structure with elastic deformation function. Therefore, it not only plays a good positioning role, helping to improve product production efficiency, but also increases the deformation that the conductive spring pin can withstand through the intermediate positioning part 2. That is, a two-stage spring structure is added to the end of the deformation part 3 near the welding part 1, making the overall deformation that can be withstood larger, effectively preventing the deformation of the deformation part 3 from being transmitted to the welding part 1, effectively reducing the stress at the welding position (i.e., the location of the welding part 1), eliminating the need for a large amount of solder, and also effectively preventing the problem of warping, effectively improving the stability and reliability of the product. The deformation part 3 refers to the elastic deformation structure of the conductive spring pin, used to pass through the bottom of the electronic tag and make elastic contact with the external wire groove.

[0022] Preferred, such as Figures 1 to 4 As shown, the deformation part 3 in this embodiment includes a first V-shaped elastic structure or a first U-shaped elastic structure. That is, the shape of the deformation part 3 in this embodiment preferably adopts a V-shaped or U-shaped structural design. This design can better achieve contact between the bottom and the wire groove, and can also better assemble the conductive spring pin into the electronic tag assembly.

[0023] like Figures 1 to 4 As shown, in this embodiment, the two ends of the positioning part 2 are connected to the welding part 1 and the deformation part 3 respectively through the first bent connecting part 4 and the second bent connecting part 5, forming an integral metal conductive spring needle. That is to say, the conductive spring needle in this embodiment adopts an integral metal spring needle structure, rather than a split structure, to ensure its reliability. Furthermore, the first bent connecting part 4 and the second bent connecting part 5 are located on the same horizontal line, which facilitates ensuring that the two ends of the positioning part 2 are at the same height when assembled to the electronic tag assembly, thus avoiding interference with other structures. Figure 3 , Figure 4 as well as Figures 7 to 10 As shown.

[0024] The optimized structure of the conductive spring pin described in this embodiment includes two types, one of which is as follows: Figure 1 and Figure 2 As shown, the positioning part 2 includes a second V-shaped elastic structure or a second U-shaped elastic structure. That is, in this optimized structure, the structural design of the positioning part 2 is similar to that of the deformation part 3, also employing a V-shaped or U-shaped elastic metal structure. However, since the positioning part 2 does not need to pass through the bottom of the electronic tag assembly, its height can be lower than the height of the deformation part 3, and its included angle can be greater than the included angle of the deformation part 3, thereby reducing the volume while ensuring a two-stage rebound (also known as a two-stage deformation structure). At this time, the first bent connecting part 4 and the second bent connecting part 5 at both ends of the positioning part 2 are located on the same straight line so that the direction of the deformation force is kept as much as possible on this straight line.

[0025] In another optimized structure of this embodiment, such as Figure 3 and Figure 4 As shown, the positioning part 2 includes an annular buffer ring. This annular buffer ring design allows for greater deformation compression, meaning the conductive spring needle can withstand increased deformation forces. At this time, the first bent connecting part 4 and the second bent connecting part 5 at both ends of the annular buffer ring are misaligned, as shown... Figure 3 As shown, it adopts a structure design similar to a single-coil spring, which can better meet the positioning requirements of the conductive spring needle and increase the elastic deformation.

[0026] Preferred, such as Figures 1 to 4 As shown, in this embodiment, the welding part 1 is a downwardly bent welding column, and the deformation part 3 is an upwardly opening deformation structure. That is, the bending direction of the welding part 1 is opposite to the opening direction of the deformation part 3, which can better reduce the stress on the welding part 1.

[0027] like Figures 5 to 10As shown, this embodiment also provides an electronic tag assembly, including the conductive spring pins as described above, and further including a first housing 6, a second housing 7, and a PCB circuit board 8. The PCB circuit board 8 is disposed between the first housing 6 and the second housing 7. The first housing is preferably an upper housing, and the second housing 7 is preferably a lower housing. The PCB circuit board 8 is provided with multiple sets of spring pin mounting structures 801. Each set of spring pin mounting structures 801 can be used to mount one conductive spring pin. The number of conductive spring pins to be assembled depends on the connection requirements directly between the wire slots. Therefore, it can be selected and adjusted according to actual needs. Each set of spring pin mounting structures 801 includes a welding position 8011, a positioning hole 8012, and a first through hole 8013. The bottom of the second housing 7 is provided with a second through hole 701 corresponding to the first through hole 8013. The welding part 1 is fixedly connected to the welding position 8011. The welding position 8011 is preferably a welding hole, so that the downwardly bent welding column can be directly inserted into the welding hole and welded and fixed. The positioning part 2 is disposed in the positioning hole 8012, and the deformation part 3 passes through the first through hole 8013 and the second through hole 701.

[0028] In this embodiment, the deformable part 3 passes through the first through hole 8013 and the second through hole 701 and emerges from the bottom of the second housing 7. Even if the force applied during assembly or disassembly is not in the vertical direction, the first through hole 8013 and the second through hole 701 can limit the deformable part 3, ensuring that the deformable part 3 will not be bent or broken.

[0029] In this embodiment, the spring pin mounting structure 801 includes two welding positions 8011 arranged side by side. The width of the positioning hole 8012 corresponds to the width of the two welding positions 8011 arranged side by side. Figure 9 and Figure 10 As shown, at this time, it can be used for assembly such as Figure 3 and Figure 4 The conductive spring pin is shown. Preferably, the PCB circuit board 8 can be provided with multiple sets of not entirely identical spring pin mounting structures 801, such as... Figures 7 to 10 As shown, part of the spring pin mounting structure 801 is used for adaptation. Figure 1 and Figure 2 The conductive spring pin shown, and another part of the spring pin mounting structure 801 are used for adapters. Figure 3 and Figure 4 The conductive spring pins shown enhance the product's adaptability. In actual use, different conductive spring pins can be assembled according to different needs.

[0030] Preferred, such as Figure 8 and Figure 10As shown, in this embodiment, the lengths of the first through hole 8013 and the second through hole 701 are greater than the deformation width of the corresponding position of the deformable part 3, and the length of the positioning hole 8012 is greater than the deformation width of the corresponding position of the positioning part 2. That is, the lengths of the first through hole 8013 and the second through hole 701, relative to the deformation width of the deformable part 3, reserve space; specifically, the first through hole 8013 and the second through hole 701 are preferably elongated holes, and after assembly, the width of the deformable part 3 is slightly smaller than the length of the elongated hole. Similarly, the length of the positioning hole 8012 also reserves space relative to the deformation width of the positioning part 2 to provide deformation space.

[0031] The specific embodiments described above are preferred embodiments of this utility model, and are not intended to limit the specific scope of this utility model. The scope of this utility model includes, but is not limited to, these specific embodiments. All equivalent changes made in accordance with the shape and structure of this utility model are within the protection scope of this utility model.
