Outer shell with metal terminal pin and processing method for same

Abstract

The invention discloses an outer shell with a metal terminal pin and a processing method for the outer shell. The processing method comprises the following steps of stamping forming, precut groove stamping, injection molding, first connecting piece cutting, proactive layer electroplating and finished product manufacturing. According to the processing method, the structure of a semi-finished product is improved, the production process is improved, production efficiency is greatly improved, meanwhile, the using amount of manpower is lowered, and meanwhile the obtained outer shell with the metal terminal pin is high in quality. Compared with a traditional production method, the processing method greatly lowers labor cost and improves unit efficiency.

Description

[0001] technical field [0002] The invention relates to an electronic component and a processing method thereof, in particular to a shell with metal lead pins and a processing method thereof. [0003] Background technique [0004] The function of the shell with metal pins of electronic products is to protect and contain the electronic and electrical components inside the shell, and the internal electrical components are connected to external circuits or other electronic products through the metal pins of the shell. Existing shells with metal pins usually include a plastic shell and external pins symmetrically fixed on both sides of the plastic shell. In the process of preparing the shell with metal pins, the external pins are usually electroplated first , and then cut off the connecting rod on the outer lead pin to become a single shell with a metal lead pin. A cross-section of the exposed metal material is formed on the lead pin. The cross-sections of the outer lead pins...

AI Technical Summary

Problems solved by technology

Due to the use of manual tinning on the outer lead pins of the product, the quality of the tin layer on the cross-section of the outer lead pins cannot be effectively controlled, resulting in fluctuations in product quality and low production efficiency; at the same time, the tin furnace itself will generate harmful gases

Moreover, when the existing shell with metal pins encounters high temperature (or reflow soldering, etc.), the external pins and internal pins (deformation) will be uneven due to the stress of the plastic, resulting in poor product quality.
