DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1-3, an electrical connector 100 includes an elongated insulative housing 30 extending along a longitudinal direction, a plurality of contacts 40 secured to the housing 30, an upper/first shell 10 attached to the housing 30, and a lower/second shell 20 attached to the housing 30 and connected to the upper shell 10. The electrical connector 100 may further include a cable or cable wires 50 linked respectively to the corresponding contacts and extending along a front-to-back direction perpendicular to the longitudinal direction, and located between the upper shell 11 and the lower shell 20 in the vertical direction perpendicular to both the longitudinal direction and the front-to-back direction.

Referring to FIGS. 4-7, the housing 30 has a thickened portion/divider 31 at a middle thereof, and the contacts 40 are arranged in a longitudinal direction at two sides of the thickened portion/divider 31. The thickened portion 31 has a front protrusion 32. The upper shell 10 has a planar main portion 11, a vertical latching piece 12 bent downward from the main portion 11, and a horizontal connecting piece 13 bent from the latching piece to overlay the lower shell 20. The latching piece 12 and the connecting piece 13 commonly forms an L-shaped securing tab (not labeled) for securing to both the housing 30 and the lower shell 20. The latching piece 12 has a hole 120 for receiving the protrusion 32 of the thickened portion 31. The connecting piece 13 has a soldering hole 130 so that solder may be applied in the hole as well as on the lower shell. The lower shell 20 has a planar main portion 21 and a middle protruding piece 22 bent upward from the main portion 21. The protruding piece 22 is received in a hole 33 of the thickened portion 31 for reinforcing securement of the lower shell 20 to the housing 30.

The upper shell 10 further includes a side wall 14 perpendicular to the main portion 11. The side wall 14 has fingers 140 at two ends thereof. Outwardly of the fingers 140 are U-shaped legs 15 each having holes 150 for engaging a mating connector. The housing 30 includes two end portions 34 each having a respective front slot 340. When the upper shell 10 is attached to the housing 30, the fingers 140 interference fit with a wall of the housing and the U-shaped legs 15 are partly received in the slots 340. The end portion 34 has a stand 341 and the lower shell 20 has hooks 23 at two ends thereof for engaging the stands 341.

The contacts 40 are insert molded at a wall 35 of the housing 30. Each contact 40 has a first contacting portion 41, a connecting portion 43, a second contacting portion 42, and a soldering tail 44. The first contacting portion 41, the connecting portion 43, and the second contacting portion 42 form a U-shaped structure and are exposed to an exterior surface of the wall 35. The tail 44 is exposed to another side of the housing 30 for soldering connection to cable wire 50.

The feature of the invention is to provide the securing tab of one of the upper shell and the lower shell around the middle region of the housing 30 for securing to both the housing and the other of the upper shell and the lower shell, thus assuring reliable rigidity of the whole shell assembly including the upper shell and the lower shell. It is noted that the upper shell 10 has the latching piece 12 to secure to the protrusion 32 of the housing, and the connecting section 13 to secure to the lower shell 20 for dual-fixation. Correspondingly, the lower shell 20 has the protruding piece 22 to be secured within the hole 33 of the housing 30, and a middle region to be secured/soldered to the connecting section 13 of the upper shell 10 for dual-fixation too. In other words, either upper shell 10 or the lower shell 20 has its own dual-fixation thereof.
