ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Present Invention
The present invention relates to an electrical connector adapter assembly for electrically connecting one electronic device to another.

comprising a first connector
20
, a second connector
30
, a first and a second printed circuit boards (PCB)
13
,
12
and a plurality of conductive poles
11
. The first connector
20
comprises a first housing
21
and three sets of first terminals
22
,
23
,
24
retained in the first housing
21
. Each of the first terminals
22
,
23
,
24
has a contact end
221
,
231
,
241
. The second connector
30
comprises a second housing
31
and two sets of second terminals
32
retained in the second housing
31
. Each of the second terminals
32
has a contact end
33
. The first PCB
13
has a set of first circuit pads
131
and a set of second circuit pads
132
on each of an upper and a lower surfaces
134
,
135
and defines a plurality of through holes
133
each connected with conductive devices
136
. The second PCB
12
has a set of third circuit pads
121
on an upper surface
124
thereof and defines a plurality of through holes
122
each connected with conductive devices
123
.
In assembly, the first connector
20
is mounted to the second PCB
12
and the first and the second connectors
20
,
30
are mounted to the first PCB
13
. The contact ends
221
of the uppermost set of the three sets of first terminals
22
are soldered to the set of third circuit pads
121
on the second PCB
12
using Surface Mounted Technology (SMT). The contact ends
231
,
241
of the other two sets of first terminals
23
,
24
are respectively soldered to the two sets of first circuit pads
131
of the first PCB
13
using SMT. The contact ends
33
of the two sets of second terminals
32
are respectively soldered to the two sets of second circuit pads
132
of the first PCB
13
. Opposite ends of the conductive poles
11
are respectively soldered into the through holes
122
of the second PCB
12

133
of the first PCB
13
and electrically connect with the conductive devices
123
,
136
in the through holes
122
,
133
.
The conventional electrical connector adapter assembly
10
has many disadvantages. First, the conventional electrical connector adapter assembly
10
has two PCBs
12
,
13
, which results in an expensive material cost. Second, soldering the conductive poles
11
into the through holes
122
,
133
is relatively complex, thereby increasing the manufacturing cost of the conventional electrical connector adapter assembly
10
. Third, it is difficult to find which of the inner set of first terminals
23
is not securely soldered to a corresponding first circuit pad
131
of the first PCB
13
and to repair it. Hence, an improved electrical connector 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 an electrical connector adapter assembly manufactured at a lower cost;
A second object of the present invention is to provide an electrical connector adapter assembly which allows bad soldered joints to be easily found and repaired.
To fulfill the above objects, an electrical connector adapter assembly of the present invention comprises a first dielectric housing, three sets of first terminals retained in the first dielectric housing, a printed circuit board (PCB), a set of conductors, a second dielectric housing and two sets of second terminals retained in the second dielectric housing. The PCB has two sets of first circuit pads and two sets of second circuit pads on an upper and a lower surfaces thereof and a number of conductive devices in the upper surface. Each conductor has a first end and a second end electrically connecting a corresponding one of the uppermost set of the three sets of first terminals and a corresponding one of the conductive devices of the PCB, respectively. The other two sets of first terminals are soldered to the two sets of first circuit pads of the PCB, respectively and the two sets of second terminals are soldered to the two sets of second circuit pads of the PCB, respectively.
In a first embodiment of the present invention, the first ends of the conductors are soldered to contact ends of the uppermost set of first terminals and the conductive devices of the PCB are positioned in through holes defined in the PCB and the second ends of the conductors are soldered into the through holes.
In a second embodiment of the present invention, the conductive devices are plated in an upper surface of the PCB and the second ends of the conductors are soldered to the conductive devices using Surface Mounted Technology (SMT).
In a third embodiment of the present invention, the first ends of the conductors are laterally soldered beside the corresponding contact ends of the uppermost set of first terminals.
In a fourth embodiment of the present invention, the first ends of the conductors are coaxial with and confront the contact ends of the uppermost set of first terminals when they are soldered thereto.
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.
