The present invention relates to a connector. The connector includes: a housing; a plurality of the terminals arranged thereon for electrically contacting with a board; a pair of arms extending from two ends of the housing, respectively; a first projection and a second projection formed on each of the arms; and a metal member arranged along the length direction of each of the arms, having a hold-down portion and a first recess for engaging with the first projection with a first buffer space existing therebetween. The metal member is spaced from the second projection by a second buffer space. When the hold-down portion is soldered to a board, the first projection or the second projection may remedy overwarp of the board or the housing.
1. A connector comprising:
a housing having two ends;
a plurality of terminals arranged on the housing for electrically contacting with a board;
a pair of arms extending from each of the ends of the housing;
a first projection and a second projection formed on each of the pair of arms; and
a metal member including: a hold-down portion and a first recess; wherein when the metal member is detachably disposed along each of the arms, the first recess is capable of accommodating the first projection with a first buffer space existing therebetween and the metal member is spaced from the second projection by a second buffer space, such that when the hold-down portion is soldered to the board, the first projection or the second projection may prevent the board or the housing from being overwarpped, wherein the housing further includes a pivot portion and the metal member further includes a second recess for engaging with the pivot portion.
2. The connector according to claim 1 , wherein the metal member further includes a stopper portion for preventing the arm from being over-deflected.
3. The connector according to claim 1 , wherein the first buffer space is 0.2 mm.
4. The connector according to claim 1 , wherein the second buffer space is 0.2 mm.
