ABSTRACT:
BACKGROUND OF THE INVENTION
1. The Field of the Invention
The present invention relates to a board to board connector, and particularly to terminals for a board to board connector.
2. Brief Description of the Prior Art
U.S. Pat. No. 5,224,866 (shown in
FIG. 6
) discloses a protrusion-type board-to-board connector
5
. The connector
5
includes an elongate dielectric housing
51
which defines a plurality of chambers
511
extending in pairs vertically and equidistantly through the housing
51
along a length thereof, and a plurality of contacts
53
received in the chambers
511
. Each contact
53
is generally J-shaped and has a base
531
, a connecting portion
532
vertically projecting from the base
531
, a curved portion
533
downwardly continuing the connecting portion
532
, and an engaging portion
535
which forms a protrusion
534
at a tip thereof. The protrusion
534
fits within a concave portion of a contact of a complementary connector when it is mated with the connector
5
. The contact
53
further comprises a fit portion in a form of barbs extending sideward for having an interference fit with the housing
51
of the connector
5
. Furthermore, to increase the compliance of the contact
53
, an arcuated recess
537
is defined between the base
53
and the connecting portion
532
.
As the profile of the contact is getting lower and the thickness of the contact is getting thinner, the conventional contact has the following disadvantages.
When mounting the contact
53
into a corresponding chamber
511
of the housing
51
, a buckling of the base
531
may occur, which causes the contact
51
to be improperly positioned in the chamber
511
. Furthermore, the compliance of the contact
53
is not enough to ensure that the contact
53
have a proper engagement with the contact of the mated complementary connector.
Hence, an improved electrical connector contact is required to overcome the disadvantages of the prior art.
BRIEF SUMMARY OF THE INVENTION
A first object of the present invention is to provide a connector with a plurality of half bellow shaped terminals.
A second object of the present invention is to provide a connector with a plurality of terminals each forming a neck between a base and a soldering tail and a plurality of embossments on opposite side surfaces of the base.
To achieve the above objects, a board to board connector includes an elongated housing and a plurality of terminals received in the housing.
The housing has a main body between a pair of opposite side walls whereby a pair of slots are defined between the side walls and the main body. A plurality of dividers depends laterally from a central wall which extends along the central line of the main body thereby defining a plurality of chambers for receiving the terminals therein.
Each terminal includes a base, a soldering tail extending outwardly from the base, a spring beam angularly extending from the base, a curved beam and a contacting beam. The base comprises a plurality of embossments in a middle thereof for preventing the base from buckling during assembly, a plurality of barbs for interferentially fit with the central wall and the side wall, and a pair of recesses beside the spring beam for improving the compliance of the contacting beam mating with a mating contact of a complementary connector. The base further has a neck at the juncture between the base and the soldering tail so that ensuring the coplanarity of the soldering tails. The spring beam, the curved beam and the contacting beam cooperatively form a half bellow shape.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description of the present embodiment when taken in conjunction with the accompanying drawings.
