ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to an electrical connector, and more particularly to an elongate electrical connector with warpage-detention device such that the coplanarity of terminal tails thereof can be ensured.
DESCRIPTION OF THE PRIOR ART
Warpage or banana effect of a housing is inevitable during making an elongate connector. Warpage of the connector will damage coplanarity of terminal tails, especially for the terminal tails are soldered to the printed circuit board through surface mount technology.
U.S. Pat. No. 5,658,154 issued to Bumsted et al on Aug. 19, 1997 discloses the use of a recess
40
and a rib
50
to overcome the warpage of the housing. Providing the ribs
50
and recesses
50
does reduce the warpage of the housing, however, when the connector is vertically attached to the printed circuit board, there is limited space to provide the ribs under the housing, especially the terminal tails extend therefrom.
In addition, because of the property of the plastic housing, it seems to be impossible to completely eliminate the warpage of the housing of the elongate connector. Accordingly, it would be more practical to provide a device which can effectively reduce the warpage of the housing when attaching the connector to the printed circuit board, while ensure coplanarity of the terminal tails.
SUMMARY OF THE INVENTION
It is an objective of this invention to provide an electrical connector with warpage-detention device such that the coplanarity of terminal tails thereof can be ensured.
In order to achieve the objective set forth, an electrical connector in accordance with the present invention comprises a dielectric elongate housing defining upper and lower faces. A plurality of discrete mating portions is spaced along the upper face of the housing. Each mating portion includes a plurality of passageways extending between the upper and lower faces. A plurality of terminals is received in the passageways. Each terminal includes a mating portion accessible in the mating portion, and a tail portion extending beyond the lower face of the housing. Warpage detention means formed in the housing includes a standoff formed on the lower face of the housing, and locking devices extending downward from opposite ends of the housing.
According to one aspect of the present invention, wherein the standoff includes a pair of wings extending from the housing.
These and additional objects, features, and advantages of the present invention will become apparent after reading the following detailed description of the preferred embodiment of the invention taken in conjunction with the appended drawings.
