Description

Radio frequency connector shell

Technical Field

The utility model relates to a radio frequency connector field especially relates to a radio frequency connector shell.

Background

The traditional design of the radio frequency connector shell mainly comprises four types, namely a long cylindrical revolving body shell processed by a traditional machine tool such as turning or milling, a cylindrical revolving body shell rolled by a stamping or bending process, and a revolving body shell with uneven wall thickness produced by a metal casting or plastic injection molding process. And fourthly, processing the shell into a revolving body shell by adopting a deep drawing process.

The long cylindrical revolving body shell is processed by a turning or milling traditional machine tool, the raw material is a bar or a pipe, and the processed shell has the characteristic of uneven wall thickness due to the need of processing steps, clamping grooves and the like on the inner hole and the outer surface of the shell. The design consumes a lot of raw materials, and the efficiency is low by using the traditional machining modes such as turning or milling, the cost is high, and the productivity is small.

The revolving body shell which is rolled by the traditional metal sheet stamping or bending process is bent and rolled into a cylinder shape, and a splicing seam is left. This concatenation seam intensity and rigidity are relatively poor, and the concatenation seam can be bloated open when receiving the expansive force of the insulator of assembly in the casing when the part assembly, arouses dimensional change, if use in the radio frequency channel, then can direct influence radio frequency performance. Meanwhile, the retention force between the inner hole of the revolving body shell and the insulator is reduced, and the insulator is easy to loosen from the revolving body shell, so that the electrical property of the connector is invalid. The cylindrical revolving body shell which is rolled by a stamping or bending process and the clamping structure are used for locking the splicing seam, but the locking force is limited, and the splicing seam is easy to expand due to the matching of a concave fastener and a convex fastener, the dimensional tolerance and the like, and the volume is also increased. If the seams are welded or otherwise joined, the manufacturing costs of the product are greatly increased.

When the shell is produced by adopting a metal casting or plastic injection molding process, if a part is designed to be the shell with uneven wall thickness or the turned shell with uneven wall thickness is produced by adopting the metal casting or plastic injection molding process, when molten metal or plastic is cooled in a mold, different parts of the part are cooled unevenly, the shrinkage is uneven, the part can generate quality problems such as warping, twisting and the like, the part with wall thickness can generate shrinkage and shortage, the internal structure is loose, and the manufacturability is poor.

The defects of the deep drawing process are as follows: firstly, a side cutting and rotary cutting die structure is required, the die structure is complex, the production is extremely unstable, the stamping efficiency is low, and secondly, the wall thickness of a product manufactured by stamping and deep drawing is uneven, so that the elastic sheet is easy to lose effectiveness.

Therefore, a new rf connector housing with a simple structure and low manufacturing cost is needed.
