Technical Field
[0001] The utility model relates to the technical field of spring pins, in particular to a corrosion-resistant data transmission spring pin. Background Art
[0002] A spring pin is a precision connector applied to electronic products such as mobile phones, widely used in various electronic products to play a role in signal transmission connection.
[0003] Existing spring pins generally consist of a barrel, a needle shaft and a spring. By connecting the barrel and the needle shaft to different components, data transmission between different components is completed. However, since the spring pin is exposed to the external environment, the surface of the spring pin is easily oxidized and corroded by the outside world, affecting its use. And since the barrel and the needle shaft on the spring pin are generally cylindrical, the contact area between the needle shaft and the barrel is small, resulting in an increase in the resistance between the two, affecting data transmission. Therefore, we propose a corrosion-resistant data transmission spring pin. Summary of the Utility Model
[0004] The purpose of the utility model is to solve the above-mentioned disadvantages in the prior art and propose a corrosion-resistant data transmission spring pin.

Specific embodiments
[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.
[0026] Refer to Figures 1-4 , a corrosion-resistant data transmission spring needle, including a syringe 7 with openings at both ends. Inside the syringe 7, there is a first needle shaft 13. One end of the first needle shaft 13 is installed with a second needle shaft 14. The first needle shaft 13 and the second needle shaft 14 are arranged in a stepped manner, and the second needle shaft 14 extends to the outside of the syringe 7. The first needle shaft 13 and the second needle shaft 14 can form an electrical connection with the syringe 7 to complete data transmission between two devices.
[0027] As Figure 2 shown, at the bottom of the syringe 7, there is a support sleeve 3 with an opening at one end. On the side surface of the bottom of the syringe 7, there is a first thread groove 6. The support sleeve 3 is sleeved on the first thread groove 6 and is in threaded cooperation with the first thread groove 6. Inside the syringe 7, there is a spring 5. The bottom end of the spring 5 abuts against the bottom of the support sleeve 3, and the top end of the spring 5 abuts against the bottom of the first needle shaft 13. During actual use, the spring 5 can support the first needle shaft 13, so that the first needle shaft 13 and the second needle shaft 14 can be telescoped along the syringe 7, thereby ensuring the normal use of the first needle shaft 13, the second needle shaft 14, and the syringe 7.
[0028] It should be noted that the support sleeve 3, the syringe 7, the first needle shaft 13, and the second needle shaft 14 are all made of metal copper. Copper has good electrical conductivity, and good data transmission performance is maintained between the support sleeve 3 and the syringe 7 and the first needle shaft 13 and the second needle shaft 14.
[0029] As Figure 1 and Figure 4As shown, a first protective sleeve 1 is sleeved on the outer surface of the syringe barrel 7. A fixing ring 2 is extended and provided at the inner top end of the first protective sleeve 1. A second thread groove 8 is opened on the top side of the syringe barrel 7. The fixing ring 2 extends to the bottom of the second thread groove 8. The outer surface of the syringe barrel 7 can be wrapped by the first protective sleeve 1, so that the outer surface of the syringe barrel 7 will not be exposed to the external environment, and thus the syringe barrel 7 can be prevented from being corroded.
[0030] As Figure 1 and Figure 4 shown, a second protective sleeve 15 is sleeved on the side of the second needle shaft 14. A peripheral edge 16 is extended and provided at the bottom of the second protective sleeve 15. The bottom of the peripheral edge 16 is in contact with the top of the syringe barrel 7. During actual use, when the second protective sleeve 15 is sleeved on the second needle shaft 14, the second needle shaft 14 can be separated from the external environment, so that the second needle shaft 14 will not be corroded by the external environment, and the use effect is improved.
[0031] It should be noted that the first protective sleeve 1 and the second protective sleeve 15 are made of conductive rubber materials. In this way, while protecting the syringe barrel 7 and the second needle shaft 14, the first protective sleeve 1 and the second protective sleeve 15 can also electrically connect the syringe barrel 7 and the second needle shaft 14 to external devices, without affecting the functions of the syringe barrel 7 and the second needle shaft 14. And the second protective sleeve 15 will also contract along with the contraction of the second needle shaft 14, without hindering the contraction of the second needle shaft 14.
[0032] As Figure 1 and Figure 2 shown, a limit ring 11 is coaxially provided at the top of the syringe barrel 7. The limit ring 11 is sleeved on the second needle shaft 14. A threaded sleeve 10 is installed at the bottom edge of the limit ring 11. The threaded sleeve 10 is sleeved on the second thread groove 8. When the threaded sleeve 10 is tightened, the bottom of the limit ring 11 abuts against the top of the peripheral edge 16, and at the same time the bottom of the threaded sleeve 10 abuts against the top of the fixing ring 2. After the first protective sleeve 1 and the second protective sleeve 15 are installed, the staff can sleeve the limit ring 11 on the second needle shaft 14, and then screw the threaded sleeve 10 into the second thread groove 8 and tighten it. In this way, the limit ring 11 can press and fix the peripheral edge 16, and at the same time the threaded sleeve 10 also presses and fixes the fixing ring 2, so that the first protective sleeve 1 and the second protective sleeve 15 can be fixed, and the fixing is convenient.
[0033] It should be noted that, as Figure 2 shown, the inner diameter of the limit ring 11 is smaller than the diameter of the first needle shaft 13. When the limit ring 11 is fixed on the syringe barrel 7 through the threaded sleeve 10, the bottom of the limit ring 11 will press on the top of the first needle shaft 13, fixing the first needle shaft 13 in the syringe barrel 7 to prevent the first needle shaft 13 from falling off.
[0034] As Figure 1 and Figure 3As shown in the figure, a plurality of conductive grooves 9 are provided on the inner side wall of the syringe barrel 7, and a plurality of conductive sheets 12 are equidistantly installed on the side surface of the first needle shaft 13. When the first needle shaft 13 is inserted into the syringe barrel 7, the conductive sheets 12 are located in the conductive grooves 9. With the cooperation of the conductive sheets 12 and the conductive grooves 9, the contact area between the first needle shaft 13 and the syringe barrel 7 can be increased, thereby reducing the resistance between the syringe barrel 7 and the first needle shaft 13 and improving the use effect.
[0035] It should be noted that, as Figure 2 shown in the figure, when the first needle shaft 13 moves to the topmost position inside the syringe barrel 7, there is a gap between the bottom of the conductive groove 9 and the bottom of the conductive sheet 12, and this gap is the same as the telescopic stroke of the first needle shaft 13 inside the syringe barrel 7. During the actual use process, when the first needle shaft 13 is telescopically extended or retracted under an external force, the conductive groove 9 will not interfere with the conductive sheet 12, so that the telescopic movement of the first needle shaft 13 will not be affected.
[0036] As Figure 1 and Figure 2 shown in the figure, a conductive rod 4 is installed on the top of the support sleeve 3, and a receiving groove 17 is provided at the bottom of the first needle shaft 13. When the first needle shaft 13 is inside the syringe barrel 7 and the support sleeve 3 is fixed at the bottom of the syringe barrel 7, the top of the conductive rod 4 extends into the receiving groove 17. During the actual use process, the cooperation between the conductive rod 4 and the receiving groove 17 can further increase the contact area between the syringe barrel 7 and the first needle shaft 13 and improve the electrical connection performance.
[0037] It should be noted that the diameter of the conductive rod 4 is the same as the inner diameter of the receiving groove 17, and the diameter of the spring 5 is larger than the diameter of the conductive rod 4. During the actual use process, the spring 5 will be sleeved on the conductive rod 4, and the top of the spring 5 will not get stuck in the gap between the receiving groove 17 and the conductive rod 4.
[0038] It should be noted that, as Figure 2 shown in the figure, when the first needle shaft 13 moves to the topmost position inside the syringe barrel 7, there is a gap between the top of the conductive rod 4 and the top of the receiving groove 17, and this gap is the same as the telescopic stroke of the first needle shaft 13 inside the syringe barrel 7. During the actual use process, when the first needle shaft 13 is contracted under the influence of an external force, the conductive rod 4 will not be blocked by the receiving groove 17, so that the first needle shaft 13 can normally expand and contract.
[0039] Specifically, when the utility model is in use, the staff sleeved the spring 5 on the conductive rod 4, then sleeved the support sleeve 3 on the bottom of the syringe barrel 7 and screwed the support sleeve 3 into the first thread groove 6 and tightened it. After that, the staff aligned the conductive sheet 12 on the first needle shaft 13 with the conductive groove 9 on the syringe barrel 7, and then inserted the first needle shaft 13 into the syringe barrel 7. The conductive sheet 12 was moved into the conductive groove 9. At the same time, the receiving groove 17 at the bottom of the first needle shaft 13 was sleeved on the conductive rod 4 to increase the contact area between the first needle shaft 13 and the syringe barrel 7 and reduce the resistance. After that, the staff sleeved the first protective sleeve 1 on the syringe barrel 7 from the bottom of the syringe barrel 7 so that the fixing ring 2 was located at the bottom of the second thread groove 8. Then the staff sleeved the second protective sleeve 15 on the second needle shaft 14 and made the surrounding edge 16 contact with the top of the syringe barrel 7. Finally, the limiting ring 11 was sleeved on the second needle shaft 14, and then the threaded sleeve 10 was screwed into the second thread groove 8 and tightened so that the limiting ring 11 pressed and fixed the surrounding edge 16, and at the same time, the threaded sleeve 10 pressed and fixed the fixing ring 2 in the second thread groove 8, so that the first protective sleeve 1 and the second protective sleeve 15 could be fixed. The syringe barrel 7 and the second needle shaft 14 could be wrapped by the first protective sleeve 1 and the second protective sleeve 15 to improve the anti-corrosion effect of the spring needle.
[0040] Furthermore, a tin plating layer is provided on the outer surface of the support sleeve 3, the outer surface of the syringe barrel 7, the first needle shaft 13 and the outer surface of the second needle shaft 14. The support sleeve 3, the syringe barrel 7, the first needle shaft 13 and the second needle shaft 14 can be protected by the tin plating layer, the wear resistance and anti-corrosion property of the outer surfaces of the support sleeve 3, the syringe barrel 7, the first needle shaft 13 and the second needle shaft 14 are increased, and the use effect is improved.
[0041] The above is only the preferred specific implementation manner of the utility model, but the protection scope of the utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the utility model, according to the technical solution of the utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the utility model.
