Electrical connector assemblies are provided that include electrical connectors having electrical contacts that have receptacle mating ends are provided. The connector housings of the provided electrical connectors include alignment members that are capable of performing staged alignment of components of the electrical connector assemblies. The provided electrical connector assemblies and the electrical connectors provided therein are capable of operating at a data transfer rate of forty gigabits per second with worst case multi-active cross talk that does not exceed a range of about two percent to about four percent.

The present invention discloses a holder carrying thereon a sensor to measure a physiological signal of an analyte in a biological fluid, wherein the sensor has a signal detection end and a signal output end, and the holder includes an implantation hole being a channel for implanting the sensor and containing a part of the sensor, a fixing indentation containing the sensor, a filler disposed in the fixing indentation to retain the sensor in the holder, and a blocking element disposed between the implantation hole and the fixing indentation to hold the sensor in the holder and restrict the filler in the fixing indentation.

An electrical connector includes a housing, a signal contact, and a ground shield. The housing includes a base having a front side and an opposite rear side. The signal contact is received in the base and has a mating segment that extends forward of the front side. The ground shield is received in the base and extends forward of the front side. The ground shield surrounds the signal contact on at least one side thereof. The ground shield includes a deflectable spring tab extending from an inner surface of the ground shield towards the signal contact without engaging the signal contact. The spring tab is positioned forward of the front side of the base. The spring tab is configured to be deflected outward by a mating connector in a direction away from the signal contact during a mating operation.

A circuit board module including a circuit board body, a connector, and a release component is provided. The connector is disposed on the circuit board body and includes a base body and a rotating button rotatably disposed on the base body. The release component is disposed on the circuit board body and includes a linking member. The linking member is movably disposed beside the rotating button and does not contact the rotating button under normal conditions. When an external force triggers the release component, the linking member is driven to contact the rotating button, so that the rotating button rotates relative to the base body. In addition, a release component is also mentioned.

A card edge connector with members configured to secure a mating component so as to improve the connector’s reliability. The connector housing may have a slot configured to receive the mating component. The slot has a first portion configured to receive a front edge of the mating component, and second portions extending from opposite ends of the first portion and configured to receive side edges of the mating component. Members are disposed in the housing and have beams curving into respective second portions of the slot. The beams of the members are configured to restrain movement of the mating component when the mating component is inserted into the slot. Such a configuration enables more reliable connections and improves the connector’s shock resistance while being compatible with mating components having a variety of sizes.

A high speed connector assembly is disclosed in this invention, which includes a receptacle connector and a plug connector. Each differential signal terminal of the receptacle connector has an L-type body, a front mating portion and a bottom mounting portion. The front mating portion includes two L-type arms having unequal length. A front end of each L-type arm disposes a resilient contact finger being perpendicular to a vertical plane. The resilient contact fingers of the two L-type arms can respectively and electrically contact with two opposite sides of one plug terminal of the plug connector, thereby forming double-sided contact. The present invention can suppress the short pile effect and reduce signal crosstalk and signal loss during transmitting the high speed signal by this double contact.

Apparatus and methods of arranging ground pins and signal pins in a card connector includes arranging a signal pins and ground pins in a card connector into at least six (6) columns divided between a primary side and a secondary side of the connector.

A high speed connector assembly is disclosed in this invention, including a receptacle connector and a plug connector. Each receptacle terminal of the receptacle connector disposes a first L-type contact piece, and each plug terminal of the plug connector disposes a second L-type contact piece. When the receptacle connector and the plug connector are electrically engaged, an extension section of the first L-type contact piece is pressed on a straight part of the second L-type contact piece, and an extension part of the second L-type contact piece is pressed on a straight section of the first L-type contact piece. So this engagement can form a double-contacts structure to restrain the short pile effect and reduce the crosstalk and loss at high speed signal transmission. A receptacle connector and a plug connector are also disclosed in this invention.

A circuit board includes: a first surface and a second surface opposite to the first surface; a through hole extending between the first surface and the second surface; a conductor covering an inner wall surface of the through hole, a first end and a second end of the conductor being terminated inside the through hole; and a wire connected to the conductor, wherein a sum of a length from a contact portion where the conductor contacts a connector pin inserted in the through hole to the first end of the conductor, and a length from a wire connecting portion where the conductor is connected to the wire to the second end of the conductor is 0.5 mm or less.

An angled circuit board connector includes a unitary connector block having first and second board-contacting faces. The first and second board-contacting faces are arranged relative to each other at an operative angle. The connector block includes a block body. The first and second board-contacting faces face outward from the block body. A first connector port is located on the first board-contacting face. A second connector port is located on the second board-contacting face. A connector trace extends through at least a portion of the block body between the first and second board-contacting faces. The connector trace electrically connects the first and second connector ports.
