Abstract: A back plate assembly includes a base plate formed with a groove having a bottom wall and a pair of side walls opposite to each other in a first horizontal direction, and an arch plate assembled into the groove and having a pair of opposite ends in the first horizontal direction. A pair of end surfaces of the ends of the arch plate abut against the side walls and a part of a middle portion of the arch plate between the ends is not in contact with the bottom wall of the groove.

Abstract: An electronic assembly includes an interposer assembly and a cable connector module coupled to the interposer assembly. The interposer assembly includes an array of compressible interposer contacts each having upper and lower mating interfaces defining separable mating interfaces. The cable connector module includes a cable connector having a module substrate including module contacts at a bottom of the module substrate coupled to the upper mating interfaces of the corresponding interposer contacts. The cable connector module includes a backshell including a backshell cavity that receives the cable connector. The backshell includes a compression member engaging the cable connector and pressing the cable connector in the direction of the interposer assembly to compress the interposer contacts.

Abstract: A loading assembly includes a base plate configured to support a circuit board placed thereon, a pressing plate configured to press an electrical member on the circuit board, and a first connection assembly connecting the pressing plate to the base plate and pressing the electrical member on the circuit board through the pressing plate. The first connection assembly includes a first nut fixed on the base plate, a first bolt passing through the pressing plate and screwed to the first nut, and a first spring sleeved on the first bolt and compressed between a head of the first bolt and the pressing plate. A first locking part is formed on the first bolt. The first locking part is pressed against an end face of the first nut when the first bolt is screwed to an installation position to prevent the first bolt from being rotated relative to the first nut.

Abstract: A card connector is disclosed having a base and a plurality of contacts. The plurality of contacts is positioned on the base. Each of the contacts has a contacting portion electrically contacting an electrical card when the electrical card inserted into the card connector. Each contact has an outer facing surface, and a supporting portion having two elastic arms extending from the base and intersecting at the contacting portion. Each of the elastic arms has a guide arm portion extending from the contacting portion at an angle of approximately 0 to 90 degrees with respect to a card insertion direction. Each guide arm portions has a smooth, ridge-shaped convex surface extending to the contacting portion and a smooth transitional surface with the outer facing surface of the contacting portion.

Abstract: A card connector for receiving an electrical card is disclosed having a base and a plurality of contacts. The plurality of contacts is positioned on the base. Each contact has a support member with two elastic arms extending away from the base. Each elastic arm has an edge that intersects together at a vertex that is elastically flexible toward and away from the base. Each contact further includes a contact element positioned at the vertex.
