ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an electrical connector, more particularly to an electrical connector having a plurality of terminals each of which has a contacting portion and an inserting portion that is substantially perpendicular to the contacting portion.
2. Description of the Related Art
FIGS. 1 and 2
show a conventional electrical connector
10
which is so-called a “Box Header Connector”. The conventional electrical connector
10
includes an elongated plastic housing
100
which is formed with two rows of terminal-receiving cavities. Each of the terminal-receiving cavities of the upper row receives a contacting portion
111
of an upper row terminal
11
which has an inserting portion
112
that is substantially perpendicular to the contacting portion
111
. Each of the terminal-receiving cavities of the lower row receives a contacting portion
121
of a lower row terminal
12
which has an inserting portion
122
that is substantially perpendicular to the contacting portion
121
. Each of the terminals
11
,
12
is solid and is square in cross-section.
The terminals
11
,
12
of the conventional electrical connector
10
illustrated in
FIGS. 1 and 2
have the following drawbacks:
1. The length of each of the terminals
11
,
12
that extends out of the housing
100
is relatively long so that it is easy to be bent or damaged by an external force. It is especially true for the terminal
11
since the length between points a and b is much longer.
2. In order to prevent to be bent or damaged by an external force, the terminals
11
,
12
must be strengthened by being solid and square in cross-section. Therefore, the manufacturing material for the terminals is increased and thus, the manufacturing cost is increased.
3. The alignment of the inserting portions
112
,
122
of the terminals
11
,
12
of the same row is difficult to be achieved since there is no reference point for the terminals
11
,
12
.
SUMMARY OF THE INVENTION
Therefore, the object of the present invention is to provide an electrical connector which can overcome the drawbacks that are associated with the prior art.
According to the present invention, an electrical connector includes a housing which is formed with at least one row of terminal-receiving cavities, and a plurality of terminals. Each of the terminals has a horizontal terminal part which is received in a corresponding one of the cavities and a vertical terminal part which is perpendicular to the horizontal terminal part. The housing has a rear wall which is formed with a horizontally extending supporting rib that is located below the cavities and that has a free end. The vertical terminal parts of the terminals abut against the free end of the supporting rib so as to ensure the vertical terminal parts of the terminals to be coplanar.
