Description

Technical Field

[0001] The utility model relates to the technical field of spring pins, in particular to a new type of signal transmission spring pin. Background Art

[0002] As a basic electrical connection component, the spring pin has the characteristics of stable structure and excellent electrical performance.

[0003] The spring pin generally consists of a barrel, a pin shaft arranged inside the barrel and a spring. During use, the barrel is fixed on the component, and then the pin shaft is connected to another component to enable signal transmission. However, when the barrel and the pin shaft are used in a vibrating environment, the pin shaft will be affected by the vibration and be briefly separated from the barrel, resulting in unstable signal transmission and poor use effect. Moreover, since the barrel and the pin shaft are directly fixed together by riveting, it is not convenient for disassembly and maintenance. For this reason, we propose a new type of signal transmission spring pin. Content of the Utility Model

[0004] The purpose of the utility model is to solve the above-mentioned disadvantages existing in the prior art, and to propose a new type of signal transmission spring pin.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: Design a new type of signal transmission spring pin, including a barrel with an opening at the top. Inside the barrel is a pin shaft, the top of the pin shaft extends outside the barrel, and at the bottom end inside the barrel is a spring. The bottom end of the spring abuts against the bottom end inside the barrel, and the top of the spring abuts against the bottom end of the pin shaft.

[0006] A connecting sleeve is provided at the top of the barrel. The connecting sleeve sleeves on the side of the top of the pin shaft, and a fixing ring is installed on the side of the top of the connecting sleeve. The bottom of the fixing ring is in contact with the top of the barrel.

[0007] A number of conductive sheets are equidistantly installed at the bottom of the connecting sleeve. The conductive sheets are located inside the barrel, and the side of the conductive sheet is in contact with the side of the pin shaft. One side of each conductive sheet is provided with an elastic gasket, and one end of the elastic gasket abuts against the inner wall of the barrel.

[0008] An annular groove is opened on the side of the top of the barrel. Arc-shaped through grooves are opened on both sides of the annular groove. A limiting block is provided inside each arc-shaped through groove. One end of the limiting block extends outside the arc-shaped through groove, and one end of each limiting block away from each other is connected with an elastic connecting block. One end of the elastic connecting block is fixed on the side wall of the annular groove. A threaded sleeve is sleeved in the annular groove, and an external thread matching the threaded sleeve is provided on the side wall of the annular groove. The threaded sleeve is in threaded cooperation with the external thread. When the threaded sleeve is located at the top of the annular groove, one end of the limiting block extends into the barrel.

[0009] A limit ring is installed on the bottom side of the connecting sleeve. When one end of the limit block close to the inside of the syringe barrel extends into the syringe barrel, one end of the limit block is located above the limit ring, and the bottom of the limit block is in contact with the top of the limit ring.

[0010] Preferably, the needle shaft is stepped, and the diameter of the bottom end of the needle shaft is larger than the inner diameter of the connecting sleeve.

[0011] Preferably, the elastic gasket is made of an elastic conductive metal material.

[0012] Preferably, the conductive sheet is arc-shaped.

[0013] Preferably, positioning grooves are symmetrically formed at the top of the syringe barrel, and positioning blocks are installed on both sides of the bottom of the fixing ring. When the bottom of the fixing ring is in contact with the top of the syringe barrel, the bottom of the positioning block extends into the corresponding positioning groove, and the outer surface of the positioning block is in clearance fit with the inner wall of the positioning groove.

[0014] Preferably, when the needle shaft moves to the topmost end of the syringe barrel, the stepped part of the needle shaft is in contact with the bottom of the connecting sleeve.

[0015] Preferably, a fillet is provided at the inner top end of the threaded sleeve.

[0016] The beneficial effects of the design scheme proposed by the present utility model in the application process are as follows:

[0017] 1. The elastic force of the elastic gasket can make the conductive sheet closely adhere to the needle shaft. The needle shaft is electrically connected to the syringe barrel through the conductive sheet and the elastic gasket, and it will not be open-circuited when used in a vibrating environment, improving the use effect.

[0018] 2. By rotating the threaded sleeve, the elastic connecting block can be squeezed, so that one end of the limit block moves above the limit ring. Under the action of the limit block and the limit ring, the connecting sleeve can be fixed inside the syringe barrel, and then the needle shaft can be fixed. The fixing is simple and the disassembly and assembly are convenient. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation mode

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0025] Refer to Figures 1 - 4 , a new type of signal transmission spring pin, including a syringe barrel 1 with an opening at the top. A needle shaft 8 is arranged inside the syringe barrel 1. The top of the needle shaft 8 extends to the outside of the syringe barrel 1. And a spring 9 is arranged at the bottom end inside the syringe barrel 1. The bottom end of the spring 9 abuts against the bottom end inside the syringe barrel 1, and the top of the spring 9 abuts against the bottom end of the needle shaft 8. In the actual use process, the syringe barrel 1 and the needle shaft 8 are respectively connected to different devices. In this way, under the action of the syringe barrel 1 and the needle shaft 8, the two devices can be electrically connected together, facilitating signal transmission.

[0026] As Figure 1 and Figure 2 shown, a connection sleeve 7 is arranged at the top of the syringe barrel 1. The connection sleeve 7 is sleeved on the side of the top of the needle shaft 8. A fixing ring 16 is installed on the side of the top of the connection sleeve 7. The bottom of the fixing ring 16 is in contact with the top of the syringe barrel 1. The needle shaft 8 can be limited by the fixing ring 16 and the connection sleeve 7 to prevent the needle shaft 8 from detaching from the syringe barrel 1.

[0027] It should be noted that the needle shaft 8 is arranged in a stepped manner, and the diameter of the bottom end of the needle shaft 8 is greater than the inner diameter of the connection sleeve 7. And when the needle shaft 8 moves to the topmost end of the syringe barrel 1, the stepped part of the needle shaft 8 is in contact with the bottom of the connection sleeve 7. In this way, the needle shaft 8 will not fall out of the syringe barrel 1 during use.

[0028] As Figure 3 shown, a plurality of conductive sheets 10 are equidistantly installed at the bottom of the connection sleeve 7. The conductive sheets 10 are located inside the syringe barrel 1, and the side of the conductive sheet 10 is in contact with the side of the needle shaft 8. One side of each conductive sheet 10 is provided with an elastic gasket 5. One end of the elastic gasket 5 abuts against the inner wall of the syringe barrel 1. In the actual use process, when the needle shaft 8 is inserted into the syringe barrel 1, the elastic gasket 5 will be squeezed by the conductive sheet 10. Then, under the elastic force of the elastic gasket 5, the conductive sheet 10 will tightly adhere to the side of the needle shaft 8. In this way, during vibration, the needle shaft 8 will not separate from the syringe barrel 1.

[0029] It should be noted that, as Figure 3As shown, the conductive sheet 10 is arranged in an arc shape, which can increase the contact area between the conductive sheet 10 and the surface of the needle shaft 8, reduce the resistance of the contact part, and improve the use effect.

[0030] It should be noted that the elastic gasket 5 is made of an elastic conductive metal material, so that the elastic gasket 5 electrically connects the syringe barrel 1 and the conductive sheet 10 together, and further enables the needle shaft 8 to be electrically connected to the syringe barrel 1 without open circuit.

[0031] As Figure 1 and Figure 2 As shown, an annular groove 11 is formed in the top side of the syringe barrel 1, arc-shaped through grooves 13 are formed on both sides of the annular groove 11, a limiting block 12 is arranged inside each arc-shaped through groove 13, one end of each limiting block 12 extends outside the arc-shaped through groove 13, and an elastic connecting block 4 is connected to one end of each limiting block 12 away from each other. One end of the elastic connecting block 4 is fixed on the side wall of the annular groove 11. During actual use, the elasticity of the elastic connecting block 4 will pull the limiting block 12, so that one end of the limiting block 12 close to the inside of the syringe barrel 1 is located in the arc-shaped through groove 13, so that during the installation process, it will not interfere with the installation of the connecting sleeve 7.

[0032] As Figure 1 and Figure 2 As shown, a threaded sleeve 2 is sleeved in the annular groove 11, and an external thread 3 matched with the threaded sleeve 2 is arranged on the side wall of the annular groove 11. The threaded sleeve 2 is in threaded cooperation with the external thread 3. When the threaded sleeve 2 is located at the top of the annular groove 11, one end of the limiting block 12 extends into the syringe barrel 1. During actual use, when the threaded sleeve 2 is rotated to the top of the annular groove 11, the threaded sleeve 2 can squeeze the elastic connecting block 4, so that the limiting block 12 moves towards the inside of the syringe barrel 1 under force.

[0033] As Figure 2 As shown, a limiting ring 6 is installed on the bottom side of the connecting sleeve 7. When one end of the limiting block 12 close to the inside of the syringe barrel 1 extends into the syringe barrel 1, one end of the limiting block 12 is located above the limiting ring 6, and the bottom of the limiting block 12 is in contact with the top of the limiting ring 6. With the cooperation of the limiting block 12 and the limiting ring 6, the connecting sleeve 7 can be fixed inside the syringe barrel 1, and further the needle shaft 8 can be prevented from coming out of the syringe barrel 1.

[0034] Specifically, when the utility model is installed, the staff sleeved the connecting sleeve 7 on the top of the needle shaft 8, so that the bottom of the connecting sleeve 7 contacts with the stepped part on the needle shaft 8. At the same time, the conductive sheet 10 contacts with the side surface of the needle shaft 8. Align the positioning block 15 at the bottom of the fixing ring 16 with the positioning groove 14 opened on the top of the syringe barrel 1, and then insert the needle shaft 8 into the syringe barrel 1. The connecting sleeve 7 is moved into the syringe barrel 1. When the bottom of the fixing ring 16 contacts with the top of the syringe barrel 1, the bottom of the needle shaft 8 contacts with the spring 9. At the same time, the positioning block 15 is moved into the positioning groove 14 to complete the positioning. And when the connecting sleeve 7 is moved into the syringe barrel 1, one end of the elastic gasket 5 installed on one side of the conductive sheet 10 abuts against the inner wall of the syringe barrel 1. The elastic gasket 5 is deformed under the extrusion of the inner wall of the syringe barrel 1, and the generated elastic force will make the conductive sheet 10 closely contact with the side surface of the needle shaft 8, and no open circuit will occur. After the needle shaft 8 is installed, the staff rotates the threaded sleeve 2. The threaded sleeve 2 moves upward along the annular groove 11 under the action of the external thread 3, and squeezes the elastic connecting block 4. The elastic connecting block 4 drives the limiting block 12 to move towards the inside of the syringe barrel 1. When the threaded sleeve 2 moves to the top of the annular groove 11, the end of the limiting block 12 close to the inside of the syringe barrel 1 moves above the limiting ring 6, and the bottom of the limiting block 12 contacts with the top of the limiting ring 6, fixing the connecting sleeve 7 inside the syringe barrel 1, which is convenient for installation.

[0035] Furthermore, as Figure 1 and Figure 3 shown, positioning grooves 14 are symmetrically opened at the top of the syringe barrel 1, and positioning blocks 15 are installed on both sides of the bottom of the fixing ring 16. When the bottom of the fixing ring 16 contacts with the top of the syringe barrel 1, the bottom of the positioning block 15 extends into the corresponding positioning groove 14, and the outer surface of the positioning block 15 has a clearance fit with the inner wall of the positioning groove 14. In the actual use process, through the cooperation of the positioning groove 14 and the positioning block 15, the fixing ring 16 and the connecting sleeve 7 can be limited to avoid the rotation of the connecting sleeve 7.

[0036] Furthermore, as Figure 4 shown, the inner top end of the threaded sleeve 2 is provided with a fillet. In this way, during the process of the threaded sleeve 2 moving along the annular groove 11, under the action of the fillet, it will guide the elastic connecting block 4 to avoid the threaded sleeve 2 being stuck.

[0037] 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.
