A probe card module including a probe card assembly and a strengthening structure is provided. The probe card assembly includes a first surface, a second surface opposite to the first surface, and a plurality of probes protruding from the first surface. The second surface includes a central zone and a peripheral zone surrounding the central zone. Projections of the probes on the second surface are located at the central zone. The strengthening structure is disposed on the second surface and includes two support bases which protrude from the peripheral zone and are away from each other, and the strengthening structure also includes an arc-shaped reinforcement assembly connected to the two support bases, where the arc-shaped reinforcement assembly protrudes toward and leans against the central zone.

An electrical connector includes a body having an accommodating hole. The body has a protruding block and a platform protruding into the accommodating hole. The platform is located below the protruding block. A conductive terminal is accommodated in the accommodating hole. The conductive terminal has a base, which bends to form an accommodating space to accommodate the protruding block. The base has a through slot, and first and second branches located at two sides of the through slot. A lower section of the first branch is limited between the first protruding block and the platform. A method for manufacturing the electrical connector includes inserting the conductive terminal with the accommodating space opening upward into the accommodating hole by the strip, and rotating the conductive terminal with the protruding block as an axis, until the lower section of the first branch is located between the platform and the first protruding block.

A plug auxiliary fitting includes a plug side-wall facing portion facing a side surface of a plug housing. The plug side-wall facing portion includes a plug electrical connecting portion capable of coming into electrical contact with a receptacle auxiliary fitting, and a plug mating lock portion that cooperates with the receptacle auxiliary fitting to prevent a mating state between a plug connector and a receptacle connector from being released. The plug electrical connecting portion and the plug mating lock portion are, in a direction parallel to a plug-connector mounting surface of a plug-side board, adjacent to each other with a notch opened toward the plug-connector mounting surface of the plug-side board interposed therebetween. The plug mating lock portion is provided with a soldering portion solderable to the plug-connector mounting surface of the plug-side board.

An electrical module is electrically conducted with an electronic component, and includes multiple conductors having a first row of conductors arranged in a left-right direction and an insulating body fixing the first row of conductors. Each conductor has a contact portion in contact with the electronic component. A distance between each two adjacent contact portions of the conductors in the left-right direction is defined as a contact interval. The first row of conductors have at least one pair of signal conductors and at least two ground conductors. Each two adjacent sides of the pair of signal conductors has one ground conductor. The contact interval from one signal conductor to its adjacent ground conductor is defined as a first contact interval. The contact interval from the other signal conductor to its adjacent ground conductor is defined as a second contact interval. The first and second contact intervals are not equal.

An electronic assembly with a first substrate and electrical connector terminals mounted on the first substrate. The electrical connector terminals have contact fingers and tracks. A bus bar may be aligned by the tracks such that contact surfaces on the contact fingers press against contact surfaces on the bus bar. The bus bar may slide in the tracks such that, when the bus bar is mounted in an electronic system including the electronic assembly, the electrical connector terminals enable the electronic assembly to slide relative to the bus bar. The electronic system may be implemented as a rack, and the electronic assembly may be or include a printed circuit board on which the electrical connector terminals are mounted. The printed circuit board may be slid in and out of the rack while power is supplied from the bus bar to components on the printed circuit board.
