Connecting the mounting portion of the housing to a mounting component can provide the normal force. The contact tail is thinner and narrower than the intermediate portion and can have extensions, which reduces the risk of permanently deforming the contact tail by the normal force and improves signal integrity performance.

The thermal plate may be rotated to press against components of a subassembly inserted into a port of the connector and fixed in this position. Protrusions on legs extending from the thermal plate may engage slots in sides of the connector.

Free ends of the first pin and the second pin are separated from each other, and are both bent and protruded toward an inner side of the insertion end portion, so as to form a first contact point and a second contact point at the free ends of the first pin and the second pin, respectively.
A high density edge connector that provides robust operation and good signal integrity. The connector is configurable to have sections tailored for high speed signals, which may be differential, or low speed signals. The connector may be assembled from signal terminals and ground terminals, either of which may be mounted within an insulative housing of the connector at any location along a row aligned with a slot of a mating interface. Shield members or lossy members may optionally be included for high speed segments, either or both of which may be electrically coupled to the ground terminals. Insertion and retention force may be limited, despite a dense array of contacts pressing on a card inserted into the connector by shaping the portions of the signal or ground contacts that act as beams generating that force. Such force may be limited with twists in the beams and/or splitting the beam portions.

A high-speed plug-in card connector comprising two terminal assemblies with reversely arranged internal structure and a housing. Each terminal assembly includes a metal sheet, a conductive plastic, and an injection-molded terminal strip. The conductive plastic is formed on the side of the metal sheet by injection molding and connects the metal sheet with a ground terminal of the terminal strip. The conductive plastics of the two terminal assemblies are located in the very middle of the connector. The conductive plastics fix the two terminal assemblies together with a snap-in connection. The housing is clamped at the end on the side where the two terminal assemblies are snapped together.

The application discloses a large current transmission connector including the pallet assembly and the socket assembly. The pallet assembly includes the pallet and the guide pillar. The socket assembly includes a socket. The socket includes mounting holes and pins. The locking structure is arranged in the mounting hole. The locking structure is used for fixing the guide pillar on the socket and for conveying a current between the pallet assembly and the socket assembly. When the guide pillar and the locking structure are fixed together, the two guide pillars not only play the role of guiding, but also can carry the large current of 50 A. Thus, this connector does not need to set aside a lot of space for mounting the power supply pins. The space of the connector is saved effectively. The miniaturization trend of the connector is met.
