Abstract

A universal serial bus connector includes a plastic housing sandwiched between a lower casing and an upper casing. The lower casing has a hollow cartridge in its front section for accommodating the plastic housing. The upper casing is placed upon the lower casing to close the opening of the hollow cartridge. A stopper plate upwardly projecting from the bottom of the cartridge and a stopper plate downwardly projecting from a face board of the upper casing prevent inadvertent displacement of the plastic housing. A resilient sensing protuberance projects from the bottom of the cartridge to engage a dent on the bottom of the plastic housing and to generate a distinct sound which indicates that the plastic housing is in its proper position. Projecting plates of tapered slope walls of the upper casing engage corresponding slits of the base board of the lower casing, facilitating in keeping the lower and upper cases in proper mutual disposition and preventing the connector from being deformed by high pressure during formation of the external insulative layer. A clip lever formed on a cable seat of the upper casing tightly clips a ground lead to the connector.

Claims

1. A universal serial bus connector, comprising:

a lower casing having a hollow cartridge provided with an entrance thereto,

an upper casing adapted to be disposed on said lower casing, thereby closing said entrance into the cartridge, and

a plastic housing sandwiched between said lower and upper casings, a cable being terminated within said plastic housing;

said lower casing comprising;

a base board,

a cable seat at a rear end thereof, the cable seat having a ground lead fixing section, a clip lever being formed thereon,

a pair of first lateral walls, each extending upwardly along a respective side of the base board, at least one latch hole being disposed on each of said first lateral walls,

an upper side of the cartridge extending between said first lateral walls and spaced from the base board, thereby providing room for said plastic housing therebetween, at least one lug upwardly extending from the upper side of the cartridge substantially at the entrance thereto, and

a pair of slits on said base board, each slit being positioned between a respective one of said first lateral walls and said cable seat;

said upper casing comprising;

a face board,

a coupling latch plate at a front end of the face board, said coupling latch plate having at least one through hole engaging said at least one lug on the upper side of the cartridge,

a clip seat extending from a rear end of the face board and cooperating with said clip lever for clipping the ground lead,

a pair of second lateral walls, each extending downwardly along a respective side of the face board, at least one latch hook extending inwardly from each of said second lateral walls and engaging said at least one latch hole on a respective first lateral wall of the lower casing, and

a pair of slope side walls, each extending downwardly from the face board between a respective one of said second lateral walls and said clip seat, a projecting plate being formed at a lower edge of each of said slope side walls, said projecting plate engaging a respective one of said slits on the base board of the lower casing;

a first stopper plate projecting downwardly from the face board of the upper casing,

a second stopper plate projecting upwardly from the base board of the lower casing,

said first stopper plate engaging a rear end of said plastic housing, said second stopper plate engaging a front end of said plastic housing, thereby preventing said plastic housing from being inadvertently displaced from a proper position thereof within said lower and upper casings; and

said base board of the lower casing further having a sensing protuberance upwardly extending therefrom, and said plastic housing further having a dent formed on a bottom thereof and engaging said sensing protuberance, once said plastic housing has been disposed in said proper position thereof.

2. The universal serial bus connector of claim 1, further including an outer insulated layer wrapping assembled said upper and lower casings and said plastic housing sandwiched therebetween.
