An electrical contact pad for electrically contacting a connector includes a first region having a first length in a longitudinal direction, and a second region having a second length in the longitudinal direction that is greater than the first length. The first region is arranged to contact a first arm of the connector and the second region is arranged to contact a second arm of the connector. The first length being smaller than the second length results in an increase in the impedance of the electrical contact pad as compared to typical contact pads which tend to correspond to low impedance regions.

An electrical connector includes a housing. The housing defines a terminal cavity that extends along a connector axis. The terminal cavity has a height that is perpendicular to the connector axis. The terminal cavity has a width that is perpendicular to the connector axis and also perpendicular to the height. The width is greater than the height. The terminal cavity adapted to accommodate a flat cable inserted in an insertion direction parallel to the connector axis. The electrical connector also includes a polarizer that extends parallel to the height. The polarizer is located within the width. The polarizer is adapted to prevent insertion into at least part of the terminal cavity.

Disclosed is a board connector including a board connector body, conductive terminals of upper and lower rows inserted inside the board connector body and a docking housing wrapped outside the board connector body, wherein a front end of the board connector is used for docking with a cable connector, the docking housing including a top wall, a bottom wall and two side walls, a docking slot is provided between the top wall and a top surface of the board connector body, and the bottom wall is provided with a blocking element that protrudes downward. As compared with the prior art, interference may occur between a front end of a blocking element and a front end of a cable connector when the cable connector is reversely inserted, thereby preventing occurrence of a reverse inserting phenomenon.

A connector includes a plurality of contacts each including first and second contact pieces provided with first and second contact portions at distal end sides, respectively, that come into contact with conductor portions of two insertable/removable connection objects when the connection objects are inserted, and a connection portion to be connected and secured to a board. The connector further includes a housing that holds the contacts in an array and includes an insertion opening of a shape that allows insertion of the connection objects and a battery from a same direction, and a terminal is arranged in the housing and spaced apart from the contacts in a width direction of the housing, the terminal including third and fourth contact pieces provided with third and fourth contact portions on distal end sides, respectively, configured to come into contact with the conductor portion of one of the connection objects and the battery.

An electrical connector includes an insulative housing, a plurality of conductive terminals retained in the insulative housing and two grounding members. The insulative housing defines an upper sidewall, a lower sidewall and two end walls connected to both ends of the upper and lower sidewalls to form a mating cavity. Each grounding member defines a body portion fixed to the insulative housing and a plurality of contacting arms extending forward from the body portion. Each contacting arm defines a pair of wing portions located on both sides thereof, and the upper and lower sidewalls define a plurality of channels and a plurality of receiving slots. The contacting arms of the grounding member are running through the channels and projecting into the mating cavity, and the wing portions are abutted against the bottom surfaces of the receiving slots to form a pre-pressure to the contacting arms.

The insulative housing defines an upper sidewall, a lower sidewall and two end walls connected to both ends of the upper and lower sidewalls to form a mating cavity. Each grounding member defines a body portion fixed to the outside of the insulative housing and a plurality of contacting arms. Each contacting arm defines a connecting portion extending forwardly from the body portion and a contacting portion bent inwardly from the connecting portion, and the upper and lower sidewalls of the insulative housing defines a plurality of channels and a plurality of ribs, the contacting portion of the grounding member protrudes into the mating cavity and the connecting portion abuts against the top surface of the rib to form a certain pre-pressure to the contacting arm.

A memory card adaptor is provided herein. The memory card adaptor may include a housing having a slot configured to accommodate a memory card. The memory card may include a signal terminal and non-signal terminals. For example, the signal terminal may be a high-speed and/or data transfer terminal, and the non-signal terminal may be a power or voltage terminal. The signal terminal may be at least partially exposed via a signal terminal opening in the housing when the memory card is accommodated in the slot. The memory card adaptor may also include at least one card-side terminal arranged so as to be capable of contacting at least one of the non-signal terminals. The at least one card-side terminal may be electrically connected, for example via a wiring line, to at least one socket-side terminal arranged so as to be capable of contacting terminals of a host socket

A connector assembly allows a conductive terminal to provide shielding to reduce any effect of external interference on signal transmission of the connector assembly so as to meet signal transmission requirements for the connector assembly, and with the use of a jumper conductor, at least partial conductive terminals on the connector assembly can be electrically interconnected with no need of any additional jumper, such that an electronic device using such connector assembly can be made compact in size desirably.
