ABSTRACT:
BACKGROUND
1. Field of the Invention
The present invention relates to electrical connectors in which terminals are arranged in multiple rows.
2. Description of the Related Art
FIG. 7
shows such an electrical connector as described above. A housing body
51
is made from an insulative material so as to extend in the direction perpendicular to the sheet. It has a support plate
52
extending forwardly from a vertically middle portion thereof. It also has upper and lower grooves
53
and
54
extending forwardly on the upper and lower surfaces of the support plate
52
and upper and lower apertures
55
and
56
communicating with the upper and lower grooves
53
and
54
, respectively. Strip-like terminals
57
and
58
are inserted into the apertures
55
and
56
from the back or right-hand side of the housing body
51
or held in the molding of the housing body
51
such that the front contact sections
57
A and
58
A are in the grooves
53
and
54
.
The terminals
57
and
58
each have a bent section
57
B or
58
B such that the rear connection sections
57
C and
58
C are aligned linearly on a circuit board P. The connection sections
57
C and
58
C are soldered to the corresponding traces of the circuit board P.
In use, a mating connector (not shown) is guided into the front section
59
A of a rectangular casing
59
which surrounds the housing body
51
such that the terminals
57
and
58
are connected to the corresponding terminals.
However, the rear ends of the two types of terminals for the above electrical connector are disposed at two different positions, presenting the following disadvantages.
(1) A large mounting space is necessary to accommodate the two types of terminals, hindering miniaturization of the equipment.
(2) It is difficult to provide planarity of the circuit at a junction between the circuit and connection portions.
(3) The circuit tends to warp, applying a high stress to either of the connection portions and separating the soldering.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the invention to provide an electrical connector having a small connection area with a circuit, realizing miniaturization of the equipment and easing the requirement for planarity of the circuit, thus proving reliable soldering.
An electrical connector relative to the invention comprises an insulating housing having a plurality of arranging surfaces; a plurality of first and second terminals having at an end contact sections placed on said arranging surfaces and at the other end connection legs projecting from the arranging surfaces to form connection portions situated in a plane.
According to the invention, the electrical connector is characterized in that at least one first terminal in an arranging surface has a plurality of connection legs spaced laterally and at least one second terminal in another arranging surface has a connection leg placed between the plurality of connection legs such that the connection portions are aligned substantially in a lateral line.
In such a structure, the connection portions of terminals on the arranging surfaces are aligned substantially in a line in a plane so that the terminals are connected to a circuit board, etc., in a short distance in the longitudinal direction of the terminals.
According to an embodiment of the invention, the first and second terminals are power and signal terminals, respectively. The power terminal has two or more connection legs with connection portions soldered to traces of a circuit board.
