A card edge connector includes an insulative housing with a pair of opposite side walls extending along a longitudinal direction with a central slot therebetween in the transverse direction perpendicular to the longitudinal direction. A pair of towers are located at two opposite ends of the housing in the longitudinal direction. The housing is essentially obliquely mounted upon a printed circuit board. Each tower has a lower/first part and an upper/second part in the vertical direction perpendicular to the longitudinal direction and the transverse direction. The width dimension in the transverse direction of the upper part is smaller than that of the lower part.

The present invention provides a flexible printed circuit board (FPCB) plug-in jig, comprising a fixture part for clamping an FPCB, wherein the fixture part comprises a first clamping element and a second clamping element which are arranged oppositely; the first clamping element and the second clamping element are configured such that an opening is formed at one end of the fixture part and a pressing portion is formed at the other end of the fixture part; a signal matching board is arranged on a surface of the first clamping element facing the second clamping element; the signal matching board is used for electrically connecting to the FPCB at one end close to the opening of the fixture part; and an additional signal port is provided at another end of the signal matching board close to the pressing portion of the fixture part.

A dual connector system includes a host circuit board with first and second electrical connectors. The first electrical connector has a housing with a card slot, first contacts and a latching feature. The second electrical connector has a housing with second contacts. The dual connector system includes a dual connector module having a module circuit board having contact pads. The dual connector module has a latch movable between a latched position and an unlatched position. The latch engages the latching feature of the first electrical connector in the latched position to hold the dual connector module in a mated position. A release mechanism is operably coupled between the dual connector module and at least one of the first electrical connector and the second electrical connector. The release mechanism forces the dual connector module to an unmated position after the latch is moved from the latched position to the unlatched position.

A battery management unit provided with a structure for preventing separation of a card edge connector and a structure for preventing separation of a card edge connector are provided. A battery management unit provided with a structure for preventing separation of a card edge connector includes a main circuit board and a sub-circuit board assembled to the main circuit board in an upright position, in which the main circuit board includes a slot block configured for insertion of the sub-circuit board, a first pivoting member including a first pivoting lever pivotably arranged around the slot block, a catching protrusion at a side of the first pivoting lever and insertable into a recess in the sub-circuit board, and a stepped portion at another side of the first pivoting lever, and a second pivoting member pivotably arranged around the slot block to press-contact the stepped portion.

An electrical connector includes an insulative housing with a plurality of contacts therein. The housing includes an elongated base extending along a longitudinal direction, and a pair of deflectable latches extending forwardly from two opposite ends of the base. The base includes a first side wall and a second side wall commonly define a receiving slot is therebetween in a vertical direction to receive a memory module therein. Each latch forms an inner face confronting a corresponding side edge of the memory module. The inner face is recessed around a bottom/root section of the latch so as to be spaced from the side edge of the memory module for not potentially damaging the side edge of the memory module during rotational installation of the memory module into the connector.

A card edge connector forms a plurality of passageways in the elongated housing to receive the corresponding contacts. Each contact has a retaining section secured to the housing, a resilient arm extending from an upper part of the retaining section with a contacting section exposed in the central slot, a soldering section extending from a lower part of the retaining section and out of the housing. A width of the passageway around the contacting section in the longitudinal direction is smaller than that around the soldering section.
