Connector

Abstract

The present disclosure provides a connector that comprises a housing and wafers. The housing comprises a top wall and a bottom wall separated from each other in a mounting direction. The wafers are mated to the housing in a mating direction and supported by the housing. A first wafer is configured to be limited in the mounting direction. A second wafer is configured to be limited in the mating direction. A possible benefit from a match between a limiting block of the first wafer and a limiting groove of the housing and a match between the limiting block of the first wafer and a limiting opening of the housing is that the first wafer is less easy to move between the top wall and the bottom wall of the housing along the mounting direction and can be more firmly supported by the housing.

The first mate limiting structure 130 is configured to be matched with the first limiting structure 30 of the housing 10 so as to limit the first wafer 100 in the mounting direction Z1-Z2.

(35) Specifically, the first mate limiting structure 130 includes a limiting block 135. When the first wafer 100 is mated to the housing 10, the limiting block 135 of the top portion 112 of the first wafer 100 and the limiting groove 35 of the top wall 12 of the housing 10 are matched with each other, and the limiting block 135 of the bottom portion 114 of the first wafer 100 and the limiting opening 36 of the bottom wall 14 of the housing 10 are matched with each other. The top portion 112 and the bottom portion 114 of the first wafer 100 are not easy to move in the mounting direction Z1-Z2 respectively relative to the top wall 12 and the bottom wall 14 of the housing 10. Therefore, the first wafer 100 is less easy to shake between the top wall 12 and the bottom wall 14 of the housing 10 along the mounting direction Z1-Z2 and can be more firmly supported by the housing 10. In addition, the first wafer 100 and the second wafer 200 are retained with each other, so the second wafer 200 is similarly less easy to shake between the top wall 12 and the bottom wall 14 of the housing 10 along the mounting direction Z1-Z2, and can be more firmly supported by the housing 10.

(36) Referring to FIG. 15 and FIG. 16, each of a top portion 212 and a bottom portion 214 of the second wafer 200 includes a second mate limiting structure 220.
