The following description of the embodiments of the present invention is provided for illustrative purposes, and other advantages and effects of the present invention will become apparent to those skilled in the art from the present disclosure.

It should be understood that the structures, ratios, sizes, and the like shown in the drawings are only used for matching the disclosure of the present disclosure, and are not used for limiting the conditions that the present disclosure can be implemented, so that the present disclosure is not limited to the technical essence, and any structural modifications, ratio changes, or size adjustments should still fall within the scope of the present disclosure without affecting the efficacy and the achievable purpose of the present disclosure. In addition, the terms "upper", "lower", "left", "right", "middle" and "one" used in the present specification are for clarity of description, and are not intended to limit the scope of the present invention, and the relative relationship between the terms and the terms is not to be construed as a scope of the present invention.

As shown in fig. 1, 2, 3 and 4, the present invention provides an insulator electroplating method, including the following steps:

s1, pouring the insulator 1 to be electroplated and a material mixing part for conductive connection into a material mixing container 3, wherein the material mixing container 3 is electrically connected with a cathode of a direct current power supply 4, the insulator 1 comprises a shell 11 and a central needle 12 which are both conductive, the central needle 12 penetrates through the shell 11, the central needle 12 is connected with the shell 11 through an insulating connecting piece 13, the material mixing part is bent, and the size of the material mixing part is matched with that of the insulator 1;

s2, the mixing container 3 is put into the plating solution to immerse the insulator 1 in the plating solution, and during the plating process, the mixing container 3 mixes the insulator 1 and the mixing parts mixed in the insulator 1 to touch the electrical connection center pin 12 and the housing 11 or the electrical connection center pin 12 and the mixing container 3.

Since the center pin 12 of the present invention is relatively small and the center pin 12 is connected to the housing 11 through the insulating connector 13, the center pin 12 is difficult to be electrically conducted directly or indirectly with the mixing container 3, thereby making it difficult to electroplate the center pin 12. In the insulator electroplating method of the present invention, the mixing container 3 mixes the insulator 1 and the mixing part, the mixing part having a curved shape so as to be able to touch the electrical connection center pin 12 and the housing 11 or touch the electrical connection center pin 12 and the mixing container 3 when mixed in the insulator 1, thereby facilitating the electroplating of the center pin 12.

In order to simplify the structure of the mixing part and facilitate touching the electric connection center pin 12 and the shell 11 or touching the electric connection center pin 12 and the mixing container 3, the mixing part can be an arc-shaped rod, a T-shaped rod or a bent rod 2. Through tests, when the material mixing part is the bending rod 2, the electroplating effect of the central needle 12 is the best.

As shown in fig. 3, further, when the material mixing part is a bending rod 2, in order to simplify the structure of the material mixing part, the bending rod 2 includes a first bending section 21 and a second bending section 22, and an included angle between the first bending section 21 and the second bending section 22 is one of an obtuse angle, a right angle, and an acute angle. When the included angle between the first bending section 21 and the second bending section 22 is a right angle, the electroplating effect of the central needle 12 is the best.

The material mixing part can be formed by fixedly connecting (for example welding) a plurality of rod pieces; the mixing part can also be integrally formed, for example, for the convenience of manufacturing, the mixing part is formed by bending a metal wire.

As an embodiment of the above-described housing 11: the housing 11 is made of a pipe, the insulating connector 13 is disposed in the housing 11, and one end of the center needle 12 extends into the inner cavity of the housing 11 through the opening of the housing 11.

As shown in fig. 1 and 2, the pipe member has a stepped shaft shape, and the insulating connector 13 is filled in a small diameter portion of the housing 11.

Furthermore, the central needle 12 is fixed on the insulating connector 13, one end of the central needle 12 extends out of the housing 11, and the other end of the central needle 12 extends into the large diameter portion of the housing 11.

The mixing container 3 can be a vibrating disc, a roller or other structures. Through tests, when the mixing container 3 is a vibrating disk, the electroplating effect of the central needle 12 is optimal.

In order to facilitate immersion of the insulator 1 in the plating solution, the mixing container 3 is provided with a through hole for allowing the plating solution to flow therethrough.

In conclusion, the insulator electroplating method provided by the invention is convenient for electroplating the center pin of the insulator. Therefore, the invention effectively overcomes various defects in the prior art and has high industrial utilization value.
