Abstract:
1. An electrical connector for being mounted onto and orthogonal to a printed circuit board comprising: an insulative housing including a base and a tongue plate protruding from and upwardly beyond an upper face of the base; a plurality of contacts having contacting portions arranged in one row along one side of the tongue plate, retaining portions extending from lower ends of the contacting portions and retained in the base, and tail portions bending forwardly from lower ends of the retaining portions for being mounted directly onto a surface of the printed circuit board; and a metal shell covering the insulative housing and including a front wall, a back wall opposite to the front wall, and a pair of side walls connecting the front and back walls, the front wall having a depressed wall depressed backwardly and forming a hollow space for the tail portions forwardly extending thereinto for inspection purpose; wherein the base has a plurality of protrusions protruding downwardly from a lower face opposite to the upper face and facing the printed circuit board, and forms a plurality of retaining slots exposed to exterior and located between each two adjacent protrusions for retaining the tail portions respectively; wherein the base has a set of stoppers formed on the lower face of the base and expanding outwardly beyond the base for upwardly resisting the metal shell and downwardly standing on the printed circuit board; wherein wherein the first and second legs form an isosceles trapezoid in condition that the second legs are located at interior of the first legs; wherein the depressed wall includes a pair of engaging walls defining dovetail slots and dovetail blocks for mating with each other, and a pair of inclined walls connecting the engaging walls and the connecting walls, all of the tail portions extend forwardly over the engaging wall, a first space measured between the engaging walls and the tongue plate is greater than a second space measured between the back wall and tongue plate; wherein the contacts comprise a grounding contact, a pair of first differential contacts for unidirectionally transmitting data, two grounding contacts, and a pair of second differential contacts for bi-directionally transmitting hybrid data arranged in sequence along a transverse direction of the electrical connector.
