Abstract

A connector is provided which includes a main body, terminals mounted in the body, and a reinforcing metal fitting mounted in the body. The fitting includes a body secured to the mating guide portion, a pair of left and right connecting arm portions connected to the base end of the body, and a pair of left and right contact arm portions connected to the base end of the connecting arm portions. The fitting further includes a first connecting leg portion connected to a connecting pad on a board being connected at the upper end of the first connecting leg portion to the lower end or base end of each contact arm portion so as to have a substantially L-shaped profile when viewed from a side of the connector.

First claim

The invention claimed is:

1. A connector comprising:
a connector main body, the connector main body including mating guide portions formed at both ends longitudinally;
terminals mounted in the connector main body; and
a reinforcing metal fitting mounted in the connector main body, the reinforcing metal fitting including
a main body portion secured to one of the mating guide portions,
a pair of left and right connecting arm portions connected to a base end of the main body portion on both left and right ends of the main body portion,
a pair of left and right contact arm portions, the left and right contact arm portions being connected at base ends thereof to the left and right connecting arm portions, respectively, and
a barrier portion formed on at least a portion of one or more of the main body portion, the left connecting arm portion and the right connecting arm portion, wherein the barrier portion is formed to prevent solder or flux to rise.

2. The connector assembly according to claim 1 , wherein the main body portion and the pair of left and right connecting arm portions are plated with nickel undercoating, and wherein the main body portion and the pair of left and right connecting arm portion are plated with gold, and wherein the barrier portion is formed by melting at least a portion of the gold with a laser beam to expose the nickel undercoating.

3. The connector assembly according to claim 1 , wherein the reinforcing metal fitting further includes a pair of left and right connecting leg portions, the left and right connecting leg portions having upper portions which are connected to the left and right connecting arm portions, respectively, the left and right connecting leg portions having lower portions which are configured to connect to one or more connection pads on a board, the barrier portion not being formed on the lower portions of the left and right connecting leg portions.
