ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention is related to an electrically connector, particularly to an electrical receptacle connector with press-fit terminals which can be firmly fitted on a spacer separated from a housing of the receptacle connector.
2. Description of the Related Prior Art
Terminals with press-fit tail have been horizontally used due to the advantages of steady orientation and causing no breakage to a printed circuit board. U.S. Pat. No. 6,083,060 discloses an electrical connector as shown in
FIG. 7
which comprises an insulating housing
11
and a plurality of terminals
12
each having a press-fit tail
125
. A bottom of the housing
11
forms a plurality of positioning poles
110
and each pole has a crossed through hole
111
. A positioning portion
120
of the terminal
12
has a pair of shoulders
121
, a protrusion
123
and an engaging portion
124
. In assembly, the terminals
12
are interference fitted in the through holes
111
through the shoulders
121
and the protrusions
123
.
However, during inserting the press-fit tail of the terminal
12
into the printed circuit board, the resistance encountered by the printed circuit board will cause the terminal
12
to move along the direction of inserting a mating connector (not shown). Furthermore, if above-mentioned terminals
12
are receptacle terminals, or the engaging portions
124
of the terminals
12
which will be inserted through the through hole
111
are broader than the positioning portion
120
, the terminals
12
can not be inserted upwardly into the through hole
111
and position the shoulders
121
in the through hole
111
.
Hence, an improved connector assembly 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 receptacle electrical connector with a plurality of terminals having a press-fit tail which can be inserted into an insulated housing of the electrical connector upward or downward selectively, and the terminal are secured therein.
To achieve the above-mentioned object, a receptacle electrical connector comprises an insulated housing having a number of passageways, a spacer and a number of terminals received in the insulated housing. The insulating housing having an engaging face and a connecting face. The passageways extend through the engaging face and the connecting face. The spacer has a first face facing the connecting face, an opposite second face and a plurality of though holes corresponding to the passageways, the second face has a pair of recesses in communication with each through hole. Each of the through holes defines a wide portion which is parallel to the recesses and is wider than the shoulders, a narrow portion which is vertical to the recesses and narrower than the shoulders. The shoulders define a width less than a width of the narrow portion plus lengths of the two recesses.
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.
