A housing is configured to receive a plug that includes an upper face, a lower face, and a front face. The housing also includes a cutout portion that traverses the upper face and the lower face, opens to the front face of the housing, extends for a length of the plug, and is formed in a direction of insertion of the plug. An opening is configured to receive the plug, which is formed on the front face of the housing and connected to the cutout so that a plug is received by the opening. A distance from the upper face to the lower face of the housing is approximately equal to a diameter of the plug.

An adaptor assembly for an OCP 2.0 form factor card for installation in a server having a side slot to accommodate OCP 3.0 form factor cards is disclosed. The adaptor assembly has an adaptor board allowing the attachment of the OCP 2.0 form factor. The adaptor board includes a socket mateable with a connector on the OCP 2.0 form factor and an edge connector mateable with a socket on the server. The assembly includes an adaptor bracket attachable to the adaptor board. The adaptor bracket has a wall that covers the side slot of the server when the adaptor assembly is inserted through the side slot.

A connector includes a flat-plate housing made of insulating resin and including a first positioning hole and a second positioning hole, a plurality of contacts held on the housing, and a first hold-down and a second hold-down made of metal and disposed to correspond to a first positioning hole and a second positioning hole, respectively. The housing includes a CPU board opposed surface to be opposed to a CPU board. The first hold-down includes a reinforcing plate part to cover the CPU board opposed surface around the corresponding first positioning hole. The second hold-down includes a reinforcing plate part to cover the CPU board opposed surface around the corresponding second positioning hole.

Systems for interfacing a printed circuit board assembly (PCBA) adapter module to a receiver housing are provided. The receiver housing may have a first interface mounted on the receiver housing via a first mount and the PCBA adapter module may have a second interface mounted on the adapter module via a second mount. One of the interfaces has a protruding feature that aligns the interfaces when matingly engaged, while the other interface has a centering hole opposite the protruding feature. The first centering hole is enlarged with respect to an axis of an insertion-angle plane such that the protruding feature substantially clears the centering hole without causing either interface to exceed a limit of free-play between that interface and its respective mount.

A housing having a height, width, and a depth direction, and cantilevered terminals having one end side secured to the housing on one side in the depth direction and having a resilient member forming a free end in an end portion on the other end side opposite to said one end side on the side opposite to the one side in the depth direction. Counterpart terminals are inserted into an insertion space within the housing from locations spaced apart in the height direction through insertion apertures occupying a predetermined area in a plane formed by the depth direction and width direction of the housing, the resilient member has contact points that contact with counterpart terminals inserted through the insertion apertures, and at least a portion of the resilient member other than the contact points, along with the contact points, is positioned within the bounds of the predetermined area in at least the plane.
