Claims
I claim:
1. An electrical connector comprising: a faceplate; a housing
having a hole therethrough; a first plurality of contacts fixedly
disposed on the sides of said hole; a first plurality of terminals
disposed on a first side of said faceplate; said housing being
disposed on a second side of said faceplate; means connecting said
contacts to respective ones of said terminals; an individual
perforation for each of said contacts, said perforation piercing
said sides and communicating with said contacts; a second
faceplate; a member secured to a first side of said second
faceplate; a second plurality of terminals disposed on a second
side of said second faceplate; a plurality of contacts disposed on
a first and second side of said member; said first and second sides
of said member being parallel and intersecting with said second
faceplate; means joining said first plurality of terminals to
respective ones of said second plurality of terminals and means
encapsulating said means for joining said first plurality of
terminals to respective ones of said second plurality of terminals.
Description
DEDICATORY CLAUSE
The invention described herein may be manufactured, used, and
licensed by or for the Government for governmental purposes without
the payment to me of any royalty thereon.
BACKGROUND OF THE INVENTION
Routine maintenance of missile systems requires that certain
voltages or signals be checked. It is necessary to check the
majority of these points inside the chassis. Many of these points
are hard to get to or identify quickly. Others are precariously
placed, making them difficult to reach without physical harm to the
technician or danger of shorting the test point to another point
within the chassis.
SUMMARY OF THE INVENTION
The present invention provides for a simple and direct manner in
which any contact within a connector may be contacted with a test
probe. The female part of the connector is fabricated such that a
small opening is provided through which a test probe may be
inserted to make contact with the contact of the connector. A
numbered opening is provided for each contact.
DESCRIPTION OF THE DRAWING
FIG. 1 is a perspective view of a female connector plug, partly cut
away.
FIG. 2 is a perspective view, partly cut away, of an adapter having
a male and female portion.
DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIG. 1, contacts 2 are numbered from 1--6 on one side
and from, 7--12 on the other side. Holes 4 are positioned in
housing 6 such that one hole is immediately adjacent each contact.
The hole may be any particular size to accommodate a particular
test probe or may be made to have a rubber grommet through which
the probe may be forced to engage contacts 2. The conductors of
cable 8 are connected to terminals 14 on the back of faceplate 10
and encapsulated to form moldform connector 12. Each terminal of
the back of faceplate 10 is connected to respective ones of
contacts 2, numbered 1--12.
FIG. 2 discloses a connector adapter which may be inserted into an
existing connector and thus provide convenient test points without
having to replace any existing cabling. Adapter 20 may be made to
coordinate with any connector design. Basically, adapter 20
provides a male portion having the desired number of contacts 32
and a female portion also having the desired number of contacts 22.
Test holes 24 are positioned adjacent each contact of the female
portion. Contacts 22 and 32 are connected to respective terminals
36 on the back of faceplates 26. The area between faceplates 26 is
then filled with molding compound 28. The adapter may be
permanently inserted into any existing connector to provide
convenient and accurate access to any contact for test purposes and
to maintain circuit continuity. Guide pins 30 and guide pin holes
34 provide orientation for the adapter of FIG. 2 or the connector
of FIG. 1.
It will be apparent to those skilled in the art that changes may be
made in the form of the apparatus disclosed without departing from
the spirit of the invention as set forth in the appended claims,
and that in some cases certain features of the invention may
sometimes be used to advantage without a corresponding use of the
other features. As examples, the female portion of the adapter
disclosed in FIG. 2 could be filled in with potting material to
provide a device that could be used only during a desired test. The
device could be inserted into a chassis to conveniently present the
test points and removed after the points have been tested. In many
cases the connector of FIG. 1 may be better utilized if the cable
conductors and the terminals on the back of faceplate 10 are not
encapsulated in a molding compound.
