Abstract
Description
Technical Field
[0001] This utility model relates to the field of USB technology, and in particular to a mold structure for a USB 3.1 10GA female connector spring-loaded fixing structure. Background Technology
[0002] With the widespread use of electronic devices, various electronic devices rapidly transfer data, typically using different connection methods of USB 3.1A female connectors to achieve electrical connections and signal transmission. Currently, the spring height of USB 3.1A female connectors is suspended. While the spring height of the plastic can be controlled before high temperatures, it easily deforms at higher temperatures, causing the spring height tail to protrude above the plastic surface, leading to brittle pins during insertion or the spring height falling below the control target. The current market for USB 3.0 and 3.1 connectors uses a suspended mold design, making spring height control unstable. To accommodate the sealing of the terminal structure, previous mold sealing relied on mold core to mold core. However, existing mold structures often prevent the terminal from being demolded because it hooks onto the plastic mold. Therefore, the upper mold design first presses down on the terminal, and the lower mold presses down on the terminal tip for sealing. This is structurally difficult to control and implement. Therefore, a mold structure for fixing the spring height of a USB 3.1 10GA female connector was designed. Utility Model Content
[0003] The purpose of this utility model is to provide a mold structure for fixing the spring height of a USB 3.1 10GA female connector, which addresses the shortcomings of the existing technology. This mold structure for fixing the spring height of a USB 3.1 10GA female connector has a novel design, simple structure, good demolding effect, and overcomes the instability of the mold sealing point.
[0004] To achieve the above objectives, this utility model is implemented through the following technical solution.
[0005] A mold structure for fixing the spring height of a USB 3.1 10GA female connector includes a female connector body, with an upper mold stop block at the upper end and a lower mold stop block at the lower end. The upper end of the female connector body is provided with spring-loaded high points arranged in a row. The lower end face of the upper mold stop block is provided with a terminal cavity arranged in a concave shape. The upper end face of the lower mold stop block is provided with a terminal pressing block arranged in a convex shape and corresponding to the terminal cavity. The upper end of the terminal pressing block is provided with a clearance cavity corresponding to the spring-loaded high points.
[0006] The upper end of the female base body is provided with a spring height stop block that corresponds to and matches the spring height tang.
[0007] The upper end of the upper mold stop is provided with a convex upper mold limiting block.
[0008] The terminal pressure block has a concave lower mold limiting groove at its upper end.
[0009] The beneficial effects of this utility model are as follows: The mold structure for fixing the spring height of a USB 3.1 10GA female connector according to this utility model includes a female connector body, and an upper mold block is installed at the upper end of the female connector body and a lower mold block is installed at the lower end. The upper end of the female connector body is provided with spring-loaded high points arranged in a row. The lower end face of the upper mold block is provided with a terminal cavity arranged in a concave shape. The upper end face of the lower mold block is provided with a terminal pressing block arranged in a convex shape and corresponding to the terminal cavity. The upper end of the terminal pressing block is provided with a clearance cavity corresponding to the spring-loaded high points. This invention features an upper mold stop at the top and a lower mold stop at the bottom of the female body. A convex terminal pressure block, corresponding to and matching the terminal cavity, is provided on the upper surface of the lower mold stop. An anti-cavity cavity, corresponding to and matching the spring-loaded terminal, is provided on the upper end of the terminal pressure block. This protects the spring-loaded terminal during injection molding. The cooperation between the upper and lower mold stops facilitates the molding of the spring-loaded terminal and overcomes the instability of the mold sealing point. During demolding, the upper and lower mold stops facilitate demolding with good demolding effect. This invention has the advantages of novel design, simple structure, good demolding effect, and overcoming the instability of the mold sealing point. Attached Figure Description
