MICRO USB straight insertion with crimped edges

Micro USB Straight Insertion with Crimped Edges

The Micro USB straight insertion with crimped edges is a vertical-mount Micro USB receptacle that combines a straight (180°) mating direction with a crimped-edge shell design. The "crimped edges" refer to the mechanically folded or pressed rim of the metal shell, which is formed by crimping rather than leaving a plain cut edge or a rolled lip.

Design and Construction

This connector is a standard 5-pin Micro USB Type-B female receptacle designed for vertical mounting on a PCB, meaning the cable plugs in straight down from above the board. The distinguishing feature is its crimped-edge shell, where the metal housing is folded or compressed at the edges to create a reinforced, interlocked rim.

Crimping serves both structural and functional purposes. First, it increases the mechanical strength of the shell, making the connector more resistant to deformation from repeated insertion and withdrawal. Second, the crimped geometry locks the shell seams together, improving shielding integrity and reducing the risk of the shell opening or loosening over time. Third, the folded edges can provide better grip and guidance during mating, helping to align the plug smoothly into the receptacle. Compared with rolled-edge designs, crimped edges tend to offer a tighter, more rigid structure at the rim.

The connector is typically available in both SMT (surface-mount) and through-hole (DIP) versions, often with locating pegs or board locks to withstand vertical insertion forces. The housing is commonly made of high-temperature LCP or PA9T plastic, while the shell is made of copper alloy or stainless steel with tin or nickel plating.

Key Characteristics

• Contact Count: 5 pins (standard Micro USB pinout)

Applications

The crimped-edge straight-insertion design is well suited to applications requiring enhanced mechanical durability and reliable shielding in a vertical-mount format. Typical applications include power banks, portable chargers, Bluetooth speakers, industrial control boards, POS terminals, and compact consumer electronics where the connector must withstand frequent plugging and unplugging while maintaining a secure, space-saving vertical profile on the PCB.
