ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to protector panels for telecommunications equipment.
DESCRIPTION OF THE RELATED ART
A protector panel containing a plurality of plug-in protectors may be installed in a telephone central office or other location. The plug-in protectors protect telecommunications equipment against sneak currents and voltage surges.
FIGS. 7A-7C
show a conventional design for a protector panel
700
. The protector panel
700
includes a substrate
710
having a plurality of holes
722
organized in clusters
720
, each cluster accommodating a plug-in protector
790
. Each hole has a respective conductive socket
730
installed in it. The sockets
730
are typically gold-plated and are quite expensive. The sockets are individually installed in the holes
722
. This installation is labor intensive and expensive.
A plug-in protector
790
can be plugged into each cluster
720
of sockets
730
. Typically, a plug-in protector is
790
installed in one of two positions. In a partially inserted position (not shown), the plug-in protector
790
forms the necessary connections to protect incoming wires from voltage surges and sneak currents, but the customer's service is disconnected. In the fully inserted position (shown in FIG.
7
B), the plug-in protector
790
protects the incoming wires and also provides connectivity to connect the customer's telephone lines. The sockets
730
must be able to grip the pins of the plug-in protector
790
while the protector is inserted or pulled out. To ensure that the sockets
730
(and the protectors) do not fall out, they are wedged into the panel substrate
710
tightly. It is essential that the protectors do not fall out; otherwise there would be no protection.
A plurality of grounding conductors
737
connect the ground lead
736
of each socket cluster
720
to a ground strip
714
on the side of the panel
700
. Each socket
730
has a wire wrap terminal
731
projecting from the bottom side of the panel
700
. Incoming wires (not shown) are individually wrapped around the wire wrap terminals
731
. This is labor intensive, and is thus an expensive process.
A simpler protector panel that can be fabricated with less labor is desired.
SUMMARY OF THE INVENTION
The present invention is a printed wiring board having resilient members for forming an electrical connection with a pin or electrode. The printed wiring board has wiring on at least one surface. The printed wiring board has at least one hole. The printed wiring board has at least one resilient elongated member adjacent to the hole. The elongated member has a conductive material on it. The conductive material forms an electrical connection between the wiring and a pin or electrode while the pin or electrode is at least partially inserted into the hole.
