USB socket and injection molding method thereof

Abstract

The invention discloses a USB socket and an injection molding method thereof. The USB socket comprises a plurality of conductive terminals, and an insulating body which is integrally formed on the conductive terminals; the insulating body comprises a base part, and a butt tongue part extending from the forward direction of the base part; each of the conductive terminals comprises a contact part molded on the butt tongue part, a fixing part which extends backwards from the contact part and is molded inside the base part, and a welding part which extends backward from the fixing part; the first side of the contact part is embedded in the butt tongue part, and the second side of the contact part is exposed out of a first tongue part; the first side of the base part is provided with an open slot at the position corresponding to the fixing part of the conductive terminal; the second side of the base part is provided with a locating slot at the position corresponding to the fixing part of the conductive terminal; and the open slot and the locating slot are at least partially overlapped in the vertical direction. The USB socket provided by the invention can reduce the manufacturing cost of the USB socket.

Description

technical field [0001] The application relates to the field of electrical connectors, in particular to a USB socket and an injection molding method thereof. Background technique [0002] Generally, a USB socket includes a plurality of conductive terminals and an insulating body integrally formed with the plurality of conductive terminals. The conductive terminal includes a contact portion, a holding portion extending backward from the contact portion, and a welding portion extending backward from the holding portion, and the contact portion is exposed on the outer surface of the mating tongue. During the injection molding process, due to the relatively long length of the contact part, it is necessary to fix the upper and lower ends of the contact part through positioning pieces, so that a hole for fixing the contact part will be formed on the butt tongue The gap, in practical application, needs to be injection molded again to fill the gap. If the gap is not filled, the appe...

AI Technical Summary

Problems solved by technology

In the injection molding process, due to the long length of the contact part, it is necessary to fix the upper and lower ends of the contact part through positioning pieces, so that a hole for fixing the contact part will be formed on the butt tongue part. The gap, in practical application, needs to be injection molded again to fill the gap, if the gap is not filled, the appearance of the product will be poor, and the gap will also accumulate dirt such as dust, which will affect the performance of the product
