Description

Connector assembly

Technical Field

The present invention relates to a connector assembly, and more particularly to a connector assembly having a plurality of insertion spaces.

Background

Generally, connectors like CXP, SFP, QSFP, ZSFP, etc. series are also available with metallic shielding cages for shielding electromagnetic interference, which can be of all-sheet-metal construction, or of all-metal die-cast construction, or of a combination of sheet-metal and metal die-cast construction, depending on the application and requirements.

For example, chinese patent publication No. CN1192462C (corresponding to U.S. patent No. US6,095,862) discloses a frame assembly (mask assembly) that is a combination of sheet metal and metal die cast construction. The frame subassembly includes the metal body of a metal die-casting to and the metal of a stamping forming covers the piece, the metal covers the piece and installs the top of metal body. In detail, in this patent, the metal body is a main body of the whole frame assembly, and therefore occupies a large structural ratio, and thus, the manufacturing cost is high when the metal body with a large volume is manufactured by metal die casting. Especially in the application of the shade assembly with a plurality of inserting spaces, the increase of the manufacturing cost is more remarkable.

Further, chinese patent publication No. CN103201911B (corresponding to US patent No. US9,325,100) discloses a connector assembly that is a combination of a metal sheet and a metal die-cast structure. The connector assembly includes an adapter frame formed by metal die casting from a solid metal die casting material, and a base plate and inner wall member formed from sheet metal. The adapter frame likewise serves as the main body of the entire connector assembly and therefore occupies a relatively large structural proportion, which likewise results in a relatively high production cost. Although the inner wall part formed by the metal sheet can reduce the cost slightly compared with the structure that the whole body is made by metal die casting, the inner wall part formed by the metal sheet is easy to deform, and the inner wall part formed by the metal sheet and the bottom plate can be combined only by the buckling mode of the bent convex sheet and the hole when being assembled, and the buckling structure has large assembly clearance, so the inner wall part is easy to loosen.
