Abstract: An electrical connector includes an insulative housing, metal terminals, and a metal shell. The terminals may be disposed in the housing such that contact portions of the terminals are exposed in openings of the housing and are arranged to contact conductive portions of a mating connector when the electrical connector and the mating connector are mated. The shell may surround external surfaces of the housing and may include a first and second portions separated by a third portion. The third portion may a width that is less than those of the first and second portions, such that a shape of the shell may include at least one recess positioned between the first and second portions. Portions of the shell may be spaced apart from the housing to define plugging spaces configured to receive legs of the mating connector.

Abstract: An electrical connector includes an insulative housing, metal terminals, and a shell surrounding the housing. Contact portions of the metal terminals are exposed in openings of the housing and are arranged to contact conductive portions of a mating connector when the electrical connector and the mating connector are mated. The shell includes a first portion having a first length and a first width, and a second portion having a second length and a second width different from the first width. The first and second portions of the shell may have heights that are different from each other, such that a step is positioned between the first and second portions of the shell. The housing may have first and second portions having different heights, such that a shoulder is positioned between the first and second portions of the housing.

Abstract: An electrical connector includes an insulative housing, metal terminals, and a shell. The metal terminals are being disposed in the housing such that contact portions of the terminals are exposed in openings of the housing and arranged to contact conductive portions of a mating connector when the electrical connector and the mating connector are mated. The shell surrounds external surfaces of the housing and includes first and second portions having first and second widths, respectively, and a third portion positioned between the first and second portions and having a third width less that each of the first and second widths. The shell also includes multiple protrusions extending outward from an external surface of the shell. The protrusions limit an insertion distance of the mating connector relative to the electrical connector when the mating connector is misaligned with the electrical connector during a mating operation.

Abstract: An electrical connector includes: an insulating housing; a first terminal assembly disposed at least partially in the housing; a plurality of guide holes disposed in the housing and extending in an insertion direction; a guide groove disposed in the housing and extending in the insertion direction; at least one mating groove disposed in the housing and extending in the insertion direction; and, optionally, a first vent hole disposed in the housing. The guide holes, the guide groove, and the mating groove may each include an inclined wall to facilitate mating with a mating connector. The guide holes may extend from a mating surface of the housing or may extend from guide posts protruding from the mating surface of the housing. The mating groove may have a plurality of heights.
