An electrical connector includes an insulative housing, a number of terminals retained in the insulative housing and a shell surrounding around the insulative housing. The insulative housing includes a base and a mating tongue extending forwardly therefrom. The mating tongue includes two opposite mating faces and two opposite side faces. The shell includes a holding portion and a mating portion. The mating portion of the shell includes two short-walls facing to the two side faces of the mating tongue and at most a long-wall facing to one of the mating faces of the mating tongue so that at least one of the mating faces of the mating tongue could be exposed to exterior in a vertical direction.

An electrical connector system including a connector having a terminal cavity within. The cavity has a rigid floor with a lock nib extending into the cavity, a first flexible beam extending into a rearward portion of the cavity and a second flexible beam extending into a forward portion. The first and second beams both overlie the floor. The system further includes a terminal having a top surface and a bottom surface defining a rigid lock edge. The terminal is received in the cavity such that the first beam engages a rearward portion of the top surface of the terminal and the second beam engages a forward portion of the top surface, thereby biasing the terminal towards the floor. The lock edge engages the lock nib, thereby preventing the terminal from being inadvertently withdrawn from the terminal receiving cavity. The connector may be formed by an additive manufacturing process.

A board connector includes terminal fittings (60) including board connecting portions (62), and a housing (10) made of synthetic resin containing a fibrous filler (80), disposed on a circuit board (90) and including a wall (18) rising in a vertical direction intersecting a surface of the circuit board (90). The wall (18) has a terminal mounting region (21) in which the terminal fittings (60) are mounted. The wall (18) includes elongated recesses (31) with a longitudinal direction aligned with the vertical direction and arranged side by side in a width direction in a distant region (22) located on a side of the terminal mounting region (21) distant from the circuit board (90).

A connector assembly and system assembling an electric connector assembly are provided. The connector assembly includes a connector housing having a plurality of terminal cavities greater than the predetermined number of electric connections so as to define an empty terminal cavity and a filled terminal cavity. The connector housing further includes a blocking member. The blocking member is the blocking member disposed within each of the empty terminal cavities. Accordingly, the blocking member closes off each of the empty terminal cavities so as to prevent fluid transfer between the terminal positioning assurance member and the connector positioning assurance member so as to prevent fluid and debris transfer between the terminal positioning assurance member and the connector positioning assurance member, or stated in another way, prevents fluid and debris transfer between the first open end and the second open end.

An enhanced safety serial bus connector (100) is provided. The enhanced safety serial bus connector (100) includes a shell (110) with a first end (110a) and a second end (110b), the first end (110a) being a terminal end of the shell (110) and having a terminal centerline (CL), and the second end (110b) being the lead end of the shell (110). The enhanced safety serial bus connector (100) also includes an insulating body (120) disposed inside the shell (110) and extending from approximately the first end (110a) to the second end (110b) and a plurality of conductors (130) substantially disposed in the insulating body (120) and extending from the first end (110a) to the second end (110b). The plurality of conductors (130) include contacts (132) that are proximate the first end (110a) and have contact centerlines (X, Y) that are substantially parallel to the terminal centerline (CL), wherein each conductor (130a-130d) of the plurality of conductors (130) are spaced apart from an adjacent conductor (130a-130d) with a distance that substantially conforms to spacing requirements of a serial bus standard that defines a voltage on the plurality of conductors (130) and is equal to or greater than a minimum enhanced safety distance requirement for the voltage defined by the serial bus standard.

An electrical connector assembly which has a housing formed of a first photocurable polymer composition. Signal contacts are positioned in the housing for transmitting signals at a determined signal speed. A dielectric constant of the photocurable polymer composition is tuned to have a higher or lower dielectric constant to be compatible with the desired signal performance characteristics of the signals transmitted over the signal contacts in the housing.
