Technical Field

[0001] The utility model relates to the technical field of electronic components, in particular to a spring bakelite thimble assembly with high-precision positioning. Background Technique

[0002] The spring bakelite thimble is a thimble component made of a spring and bakelite material. Bakelite is a material with good insulation performance and mechanical strength. The spring bakelite thimble is usually used in fields such as electronic devices and mechanical devices. The function of the spring is generally to provide an elastic force so that the thimble can stretch or apply pressure within a certain range, and the bakelite part plays roles such as insulation, wear resistance, and high temperature resistance.

[0003] In the prior art, the spring thimble is generally directly inserted into the hole of the bakelite without too many restrictions, resulting in a relatively loose assembly effect and a poor positioning effect. Therefore, those skilled in the art propose a spring bakelite thimble assembly with high-precision positioning to solve the above problems. Content of the Utility Model

[0004] In order to make up for the above deficiencies, the utility model provides a spring bakelite thimble assembly with high-precision positioning, aiming to improve the problem that in the prior art, the spring thimble is generally directly inserted into the hole of the bakelite without too many restrictions, resulting in a relatively loose assembly effect and a poor positioning effect.

[0005] To achieve the above object, the utility model provides the following technical solution: A spring bakelite thimble assembly with high-precision positioning, including a bakelite block, an annular groove is opened inside the bakelite block, a thimble cylinder is slidably connected to the inner side of the bakelite block, a rubber ring is fixedly connected to the outer side of the thimble cylinder, a base is fixedly connected to the bottom of the thimble cylinder, a connecting column is fixedly connected to the bottom of the base, a sliding disk is slidably connected to the inside of the thimble cylinder, a thimble head is fixedly connected to the top of the sliding disk, and a lubrication assembly is arranged inside the thimble cylinder, and the lubrication assembly is used to add lubricating oil to the outer side of the thimble head.

[0006] Further, the lubrication assembly includes two through slots, and the through slots are opened on the inner side of the top end of the thimble cylinder.

[0007] Further, two receiving grooves are opened on the outer side of the top of the sliding disk.

[0008] Further, a conductive column is fixedly connected to the top of the base, and a spring is sleeved outside the conductive column.

[0009] Further, one end of the spring is fixedly connected to the top of the base, and the other end of the spring is fixedly connected to the bottom of the sliding disk.

[0010] Furthermore, the outer side of the top needle head is slidably connected to the through port of the top needle barrel.

[0011] Furthermore, the outer part of the rubber ring fits with the inner side of the annular groove.

[0012] Furthermore, the top of the base fits with the bottom of the phenolic block.

[0013] The utility model has the following beneficial effects:

[0014] 1. In the utility model, by assembling the top needle barrel into the inner side of the phenolic block, the rubber ring is snapped into the inner side of the annular groove, so that the assembled top needle barrel has better stability, and the top of the base will fit with the bottom of the phenolic block, making the overall structure have a better positioning effect.

[0015] 2. In the utility model, by injecting a small amount of lubricating oil at the positions of the two through port grooves, it will flow into the interior of the two receiving grooves for storage when the top needle head slides. In this way, the top needle head can be smeared with lubricating oil when sliding, making the sliding of the top needle head smoother and the sensitivity of the overall mechanism higher.

[0022] 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Referring to Figures 1 - 3 , an embodiment provided by the present invention: a spring bakelite thimble assembly with high-precision positioning, including a bakelite block 1. An annular groove 2 is opened inside the bakelite block 1. A thimble barrel 3 is slidably connected to the inner side of the bakelite block 1. A rubber ring 4 is fixedly connected to the outer side of the thimble barrel 3. A base 5 is fixedly connected to the bottom of the thimble barrel 3. A connecting column 6 is fixedly connected to the bottom of the base 5. A sliding disk 9 is slidably connected to the inside of the thimble barrel 3. A thimble head 10 is fixedly connected to the top of the sliding disk 9. A lubricating assembly is arranged inside the thimble barrel 3. The lubricating assembly is used to add lubricating oil to the outer side of the thimble head 10. The thimble barrel 3 is assembled into the inner side of the bakelite block 1, so that the rubber ring 4 is engaged into the inner side of the annular groove 2. In this way, the thimble barrel 3 has better stability after assembly, and the top of the base 5 will be in contact with the bottom of the bakelite block 1, so that the overall structure has a better positioning effect.

[0024] Referring to Figures 2 - 4 , the lubricating assembly includes two through slots 11. The through slots 11 are opened inside the top end of the thimble barrel 3. Two receiving grooves 12 are opened on the outer side of the top of the sliding disk 9. A conductive column 7 is fixedly connected to the top of the base 5. A spring 8 is sleeved outside the conductive column 7. One end of the spring 8 is fixedly connected to the top of the base 5, and the other end of the spring 8 is fixedly connected to the bottom of the sliding disk 9. The outer side of the thimble head 10 is slidably connected to the through hole of the thimble barrel 3. The outer side of the rubber ring 4 is in contact with the inner side of the annular groove 2. The top of the base 5 is in contact with the bottom of the bakelite block 1. A small amount of lubricating oil is injected at the positions of the two through slots 11. When the thimble head 10 slides, it will flow into the inside of the two receiving grooves 12 for storage. In this way, the thimble head 10 can be smeared with lubricating oil when it slides, making the sliding of the thimble head 10 smoother and the sensitivity of the overall mechanism higher.

[0025] Working principle: First, the ejector barrel 3 is assembled inside the electrically conductive block 1, so that the rubber ring 4 is engaged inside the annular groove 2, thus making the ejector barrel 3 have better stability after assembly. And the top of the base 5 will be in contact with the bottom of the electrically conductive block 1, making the overall structure have a better positioning effect. By pressing the ejector head 10, the bottom of the ejector head 10 is in contact with the top of the conductive column 7, and then the connecting column 6 is in contact with the pad of the PCB board to conduct electricity. In addition, a small amount of lubricating oil is injected at the positions of the two through ports 11 and will flow into the inside of the two receiving grooves 12 for storage when the ejector head 10 slides. In this way, the ejector head 10 can be smeared with lubricating oil when it slides, making the sliding of the ejector head 10 smoother and the sensitivity of the overall mechanism higher.

[0026] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
