A connector that is mounted on an external mount substrate and in or from which an external pluggable substrate is inserted or extracted in an insertion-extraction direction Die includes: pin groups each including a plurality of aligned contact pins; an outer housing holding the pin groups and a frame attached to the outer housing. The outer housing has a main body and a protruding part which protrudes in the insertion-extraction direction Die from the main body and in which a slot opening in or from which the pluggable substrate is inserted or extracted is formed. The frame surrounds the whole circumference of the protruding part and is installed on an installation surface of the main body substantially orthogonal to the insertion-extraction direction Die.

A circuit board assembly includes a circuit board and an electrical connector having a connector housing holding contacts in a contact array. The connector housing has a mating end configured to be mated with a mating electrical connector in a mating direction. The electrical connector has cables terminated to the contacts and extending from a cable end. A connector mount is used to locate the electrical connector relative to the circuit board. A bracket is coupled to the mounting surface of the circuit board. A biasing member is coupled to the bracket and the mounting feature and is compressible along a compression axis parallel to the mating direction to allow the electrical connector to float in the mating direction relative to the circuit board.

A universal serial bus type-C (USB-C) plug includes a barrel, signal contacts, retention latches, and a surface mounting assembly. The barrel has an insertion end, a contact end opposite the insertion end, and a pair of long sides and a pair of short sides between the contact end and the insertion end. The signal contacts and retention latches are arranged within the barrel, the signal contacts along the long sides, and the retention latches along the short sides. The surface mounting assembly is connected to the contact end of the barrel and includes surface mount contact points each connected to a respective signal contact, and retention latch contact points each connected to a respective retention latch. Each surface mount contact point extends substantially perpendicular to the signal contacts, and each retention latch contact point extends substantially perpendicular to the retention latches and to the surface mount contact points.

A high frequency electrical connector including a plastic housing and a plurality of contacts retained by the plastic housing. The contacts include a plurality of differential pair signal contacts and a plurality of grounding contacts beside the signal contacts, respectively. The plastic housing includes the insulative plastic portion and the conductive plastic portion to which the insulative plastic portion is assembled. The signal contacts are retained in the insulative plastic portion while the grounding contacts are retained in the conductive plastic portion wherein the signal contacts are isolated from the conductive plastic portion via the insulative plastic portion.

An electrical connector assembly including a first connector and a second connector mated with each other. The first connector includes an insulative housing with a mating cavity sounded by opposite top wall and bottom wall, two opposite side walls and a rear wall. The rear wall forms opposite inner surface and outer surface. A plurality of contacts are retained to the housing and include the contacting sections exposed in the mating cavity and soldering sections exposed outside of the housing and behind the rear wall. A plurality of inner partitions are formed on the interior surface of the rear wall and extend into the mating cavity to separate the contacting sections of the neighboring contacts, respectively. A plurality of outer partitions are formed on the exterior surface of the rear wall to separate the soldering sections of the neighboring contacts.

A plurality of pairs of contact terminals accommodated in a card edge connector include back surface members having one ends to which lead wires are connected and another ends being folded to form movable members. Until a circuit board of a control unit is inserted, end portions of the movable members are held in conductive contact with each other. When the circuit board is inserted, the movable members are separated and brought into contact with copper foil terminals. When the circuit board is removed, the movable members plastically deform and are opposed to each other with an initial gap smaller than a thickness dimension of the circuit board. With this arrangement, wiring inspection may be performed with opposed movable members shorted to one another, but for subsequent circuit board insertion at the second or subsequent insertion and removal of the circuit board, the movable members will be slightly separated by a gap to suppress slide abrasion during insertion.

An electrical connector includes a housing having a first end and a second end with a mating slot formed between the first and second ends configured to receive a mating connector having contact pads. A leadframe assembly is disposed in the housing. The leadframe assembly has a contact array including ground contacts and signal contacts interspersed between corresponding ground contacts. The leadframe assembly has an overmold body supporting the ground and signal contacts. The overmold body has lossy ground absorbers coupled to corresponding ground contacts. The lossy ground absorbers are manufactured from lossy material absorbing electrical resonance propagating through the leadframe assembly.

An improved broadside coupled, open pin field connector. The connector incorporates lossy material to selectively dampen resonance within pairs of conductive members connected to ground when the connector is mounted to a printed circuit board. The material may also decrease crosstalk and mode conversion. The lossy material is selectively positioned to substantially dampen resonances along pairs that may be connected to ground without unacceptably attenuating signals carried by other pairs. The lossy material may be selectively positioned near mating contact portions of the conductive members. Multiple techniques are described for selectively positioning the lossy material, including molding, inserting lossy members into a housing or coating surfaces of the connector housing. By using material of relatively low loss, loss when the conductive members are used to carry signals is relatively low, but an appreciable attenuation of resonances is provided on pairs connected to ground.
