Description
A device for seamless gold plating of inner conductors Technical Field
[0001] This utility model relates to the field of internal conductors, and in particular to a device for seamless gold plating of internal conductors. Background Technology
[0002] The inner conductor usually refers to the central conductor in transmission lines such as coaxial cables and coaxial lines. Taking a coaxial cable as an example, it consists of an inner conductor, an insulation layer, an outer conductor (shielding layer), and a sheath from the inside out. The inner conductor is generally a round metal wire, such as copper wire or copper-clad steel wire, and its function is to carry the transmitted electrical signals.
[0003] In many fields such as electronics and communications, inner conductors are widely used in various transmission lines, electronic components and other equipment. In order to improve the performance of inner conductors, such as conductivity, corrosion resistance and wear resistance, gold plating is a common surface treatment process.
[0004] In traditional gold plating, the inner conductor is manually placed directly into the gold plating bath, and then its surface is gold-plated through a chemical reaction. However, the inner conductor is not restrained in the gold plating bath, which leads to poor gold plating results in some areas. Moreover, the inner conductor still needs to be manually removed after gold plating, but chemical residues from the gold plating bath remain on the surface of the inner conductor, which may affect health. Therefore, a traceless gold plating device for inner conductors is proposed to solve the above problems. Summary of the Invention
[0005] To overcome the above shortcomings, this utility model provides a traceless gold plating device for inner conductors, which aims to improve the existing technology where the inner conductor is not limited in the gold plating bath. This results in poor gold plating effect in some parts of the inner conductor, and the inner conductor still needs to be manually removed after gold plating. However, the surface of the inner conductor will still have chemical residues from the gold plating bath, which may affect health.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Referring to Figures 1-5, one embodiment of this utility model is provided: a traceless gold plating device for inner conductors, including a gold plating pool 1, a mounting frame 2 fixedly installed on the surface of the gold plating pool 1, a partition 3 fixedly installed inside the gold plating pool 1, a pulling component 4 for pulling the gold-plated inner conductor inside the mounting frame 2, and a limiting component 5 for limiting the inner conductor inside the gold plating pool 1. First, the inner conductor to be gold-plated can be placed inside the gold plating pool 1, and then the inner conductor can be limited by the limiting component 5 inside the gold plating pool 1. After the inner conductor is gold-plated, each group of inner conductors can be taken out by pulling component 4, thereby achieving the advantage of gold plating the inner conductor.
[0032] Referring to Figures 1-5, the pulling assembly 4 includes a mounting sleeve 41. A first electric push rod 42 is fixedly mounted on the top of the inner wall of the mounting sleeve 41. A double-sided toothed plate 43 is fixedly mounted on the telescopic end of the first electric push rod 42. Two sets of gears 44 are arranged inside the mounting sleeve 41, and the double-sided toothed plate 43 meshes with the gears 44. Two sets of grippers 45 are arranged inside the mounting sleeve 41. The grippers 45 are fixedly mounted inside the sleeve by a shaft pin and the front and rear sides of the gears 44. Through the mutual cooperation of the mounting sleeve 41, the first electric push rod 42, the double-sided toothed plate 43, the gears 44, and the grippers 45, when... When the gold-plated inner conductor needs to be removed, the first electric push rod 42 can be activated. The telescopic end of the first electric push rod 42 drives the double-sided toothed plate 43 to move to the bottom. The movement of the double-sided toothed plate 43 to the bottom drives the gear 44 to rotate. The rotation of the gear 44 drives the gripper 45 to rotate inward or outward, thereby clamping the inner conductor. Then, the mounting sleeve 41 can be pulled upward to remove the gold-plated inner conductor. The pulling assembly 4 also includes a screw 46. The left end of the screw 46 is rotatably mounted on the left side of the inner wall of the mounting bracket 2 through a bearing, and the right end of the screw 46 passes through to the mounting sleeve 41. On the right side of mounting bracket 2, a motor 47 is fixedly installed. The output end of the motor 47 is fixedly installed to the right end of the screw 46. A screw block 48 is threaded onto the surface of the screw 46. A second electric push rod 49 is fixedly installed at the bottom of the screw block 48. The telescopic end of the second electric push rod 49 is fixedly installed to the bottom of the mounting sleeve 41. Through the cooperation of the screw 46, motor 47, screw block 48, and second electric push rod 49, when the motor 47 is started, the output end of the motor 47 drives the screw 46 to rotate. The rotation of the screw 46 drives the screw block 48 to the left or right. The movement of the screw block 48 causes the second electric push rod 49 and the mounting sleeve 41 to move, thereby adjusting the position of the mounting sleeve 41 and allowing the inner conductor at different positions in the gold plating pool 1 to be removed. A limit rod 6 is fixedly installed inside the mounting frame 2. The right end of the limit rod 6 extends through to one side of the screw block 48. The limit rod 6 and the screw block 48 are threaded together. The limit rod 6 can limit the movement of the screw block 48, preventing it from being affected by the screw rod 46 during movement, which would cause the screw block 48 to shake and fail to effectively clamp the inner conductor with the gripper 45.
[0033] Referring to Figures 1-5, the limiting assembly 5 includes four sets of first retaining rings 51 and four sets of second retaining rings 52. Limiting blocks 53 are fixedly installed on the back of the first retaining rings 51 and the front of the second retaining rings 52. Stoppers 54 are fixedly installed on the front and rear sides of the inner wall of the gold plating pool 1. Springs 55 are fixedly installed on the outer ends of the limiting blocks 53. The outer ends of the springs 55 and the inner sides of the stoppers 54 are fixedly installed. Through the mutual cooperation of the first retaining rings 51, second retaining rings 52, limiting blocks 53, stoppers 54, and springs 55, when the inner conductor is placed inside the gold plating pool 1, and the inner conductor is located inside the first retaining rings 51 and second retaining rings 52, the stoppers 54, first retaining rings 51, and second retaining rings 52 are constantly subjected to the elastic force of the springs 55, thereby allowing the first retaining rings 51 and second retaining rings 52 to move towards each other. The inner conductor is moved closer to one side to limit its movement and prevent it from shaking during gold plating. A stabilizing rod 7 is fixedly installed on the outer side of the limiting block 53. The back of the stabilizing rod 7 extends through to the outer side of the stop block 54 and slides with the stop block 54. A spring 55 is sleeved on the surface of the stabilizing rod 7. The stabilizing rod 7 limits the spring 55 and prevents it from deforming under pressure, which would cause the first retaining ring 51 and the second retaining ring 52 to be unable to stably limit the inner conductor. A round block 8 is fixedly installed on the outer end of the stabilizing rod 7. The inner side of the round block 8 contacts the outer side of the stop block 54. The round block 8 limits the stabilizing rod 7 and prevents the spring force on the stabilizing rod 7 from being too large, which would cause the stabilizing rod 7 to detach from the stop block 54.
[0034] Working principle: First, the inner conductor to be gold-plated is placed inside the gold plating bath 1, with the inner conductor located inside the first retaining ring 51 and the second retaining ring 52. Because the stop block 54, the first retaining ring 51, and the second retaining ring 52 are constantly subjected to the elastic force of the spring 55, the first retaining ring 51 and the second retaining ring 52 can move closer to each other, thus limiting the inner conductor. At this time, the chemicals inside the gold plating bath 1 can be used to perform the gold plating reaction on the inner conductor. After the inner conductor is gold-plated, the motor 47 can be started. The output end of the motor 47 drives the screw 46 to rotate. The rotation of the screw 46 drives the screw block 48 to move to the left or right. The second electric push rod 49 and the mounting sleeve 41 are moved by the motor. When the mounting sleeve 41 is at the top of the inner conductor, the second electric push rod 49 can be activated. The telescopic end of the second electric push rod 49 moves the mounting sleeve 41 and the gripper 45 to the bottom. Then the first electric push rod 42 can be activated. The telescopic end of the first electric push rod 42 moves the double-sided toothed plate 43 to the bottom. The movement of the double-sided toothed plate 43 to the bottom drives the gear 44 to rotate. The rotation of the gear 44 drives the gripper 45 to rotate inward or outward, thereby clamping the inner conductor. Then the reverse steps can be repeated to remove the gold-plated inner conductor, thus achieving the advantage of gold plating the inner conductor.
[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
