ABSTRACT:
FIELD OF THE INVENTION
This invention relates to a method for manufacturing an insulation displacement connector and a structure thereof, and more particular to a method for manufacturing an insulation displacement connector and a structure thereof which can accelerate the production speed thereof.
BACKGROUND OF THE INVENTION
Generally, IDCs (Insulation Displacement Connectors) utilize double rows of terminals to connect to the conducting wires. The double rows of terminals are fixed in two terminal seats, wherein the terminal seats can be perpendicular or parallel to the printed circuit board for respectively applied to a relatively larger space located in one of a back end and an upper end of a pedestal of a keystone jack. Please refer to FIG.
1
. It illustrates a three-dimensional assembling view of the insulation displacement connector in the prior art. The method for manufacturing the IDC
10
in
FIG. 1
includes the steps described as follows: respectively injection molding a plastic case
11
and an inner scoop
12
, affixing eight terminals
13
to the inner scoop
12
by an artificiality or an auto-equipment, putting the inner scoop
12
into the plastic case
11
through aiming the eight terminals
13
pf the inner scoop
12
at eight pre-kept holes
14
of the plastic case
11
, and holding the inner scoop
12
in the plastic case
11
via fixing a tenon
15
of the plastic case
11
in a cavity
16
of the inner scoop
12
. When the terminals
13
proceed a high-frequency signal transmission, the conductors of terminals
13
and the atmosphere therearound will form a capacitance.
Please refer to FIG.
2
. It illustrates a three-dimensional assembling view of the IDC in
FIG. 1 and a
printed circuit board in the prior art. In this situation, the IDC
10
formed by the steps described above is perpendicularly assembled with a printed circuit board
20
. Because the IDC is assembled as one unity by fixing and assembling the inner scoop
12
and the plastic case
11
, the manufacturing processes are complicated as shown above. Particularly, the affixing way of the eight terminals
13
to affix to the inner scoop
12
not only is inconvenient but also causes an unstable disadvantage while the eight terminals
13
are fixed in the plastic case
11
.
Because of the technical defects described above, the applicant keeps on carving unflaggingly to develop a “method for manufacturing insulation displacement connector and structure thereof” through wholehearted experience and research which.
