Electrical connector

An electrical connector, comprising:

• an insulative housing defining a front mating face and a rear mounting face, and provided with a receiving cavity and two rows of passageways both recessed backwards from the mating face, the receiving cavity extending along a transverse direction to form a strip-like shape and sandwiched between the two rows of passageways;
• and
• a retainer having a plurality of first latching portions and a plurality of second latching portions on both an upper surface and a lower surface;
• wherein the first latching portions are closer to an insertion end of the retainer than the second latching portions, the retainer is inserted into the receiving cavity until the first latching portions passing across a rear surface of a limiting wall to make the retainer be fixed in a temporary locking position, when the second latching portions passing across the rear surface, the retainer is fixed in a final locking position.

An electrical connector, comprising:

• an insulative housing having a mating face and a mounting face opposite to each other, and comprising a plurality of passageways passing through thereof along a front-and-back direction for receiving corresponding contacts, a receiving cavity recessed backwards from the mating face and two rows of elastic walls extending forwards;
• and
• a retainer assembled into the insulative housing;
• wherein the retainer is of a tongue shape and provided with a plurality of first latching portions and a plurality of second latching portions, the first latching portions and the second latching portions are staggered along the front-and-back direction, the retainer is assembled and locked in the insulative housing without dropping out of the insulative housing via the first latching portions;
• after the contacts assembled into the insulative housing, the retainer is pushed towards the mounting face by an external force and an inserting portion of the retainer enters into an plugging space formed between the two rows of elastic walls, until the second latching portions locked in receiving cavity and the inserting portion pressing against the two rows of elastic walls on both sides thereof to move in opposite directions.
