ABSTRACT:
FIELD OF THE INVENTION
The present invention relates generally to electrical connectors, and more particularly to a new and improved insulation displacement-pin receiving type electrical connector which is able to electrically connect telephone lines to network equipment through means of a card edge type electrical connector, as well as to an assembly of the insulation displacement-pin receiving electrical connector, the card edge type electrical connector, and any one of several different types of over-voltage protection printed circuit boards, wherein all electrical connections are achieved in an entirely solderless manner.
BACKGROUND OF THE INVENTION
In the telecommunications industry, it is well-known to electrically interconnect telephone lines to network equipment through means of a card edge type electrical connector. More particularly, as best seen, for example, in
FIGS. 1 and 2
, a conventional or PRIOR ART electrical connection arrangement or assembly for achieving the aforenoted type connections within the telecommunications art is disclosed and is generally indicated by the reference character
10
. The electrical connection arrangement comprises an elongated card edge type electrical connector
12
which is provided with a plurality of electrical contacts
14
which are disposed in an elongated or serial array along the length of the connector
12
and which respectively define a plurality of upstanding pin contact portions
16
protruding externally from the upper region of the connector
12
, and a plurality of edge contact portions
18
which are disposed internally within the bottom region of the connector
12
. The edge contact portions
18
are adapted to mate in a well-known manner with a printed circuit board, not shown, which is operatively connected to network equipment, also not shown, and which is adapted to be inserted into a recessed portion
20
of the connector
12
so as to electrically engage the edge contact portions
18
. The upstanding pin contact portions
16
are adapted to be electrically engaged with telephone lines
22
through means of well-known wire-wrap type connections
24
.
The electrical connection arrangement or assembly
10
is completed by the inclusion of an over-voltage protection printed circuit board
26
which is provided with a plurality of gas tube over-voltage protection devices
28
that are designed to fail upon sensing or being exposed to over-voltage conditions so as to protect the telecommunications circuits and network equipment. The over-voltage protection printed circuit board
26
is seen to be disposed atop the card edge connector
12
and comprises a plurality of apertures for permitting passage of the pin contacts
16
therethrough. In order to complete the entire assembly
10
, it is to be appreciated that each one of the pin contacts
16
may be soldered to the over-voltage protection printed circuit board
26
as at
30
, although the printed circuit board
26
could be connected to the pin contacts
16
by means of solderless connections. In addition, each one of the wire wrap connections
24
is soldered to its respective pin contact
16
as at
32
, as best illustrated in and seen from FIG.
1
. It can thus be appreciated that the fabrication of this assembly or arrangement can be quite time consuming and labor intensive, particularly in view of the different processes or procedures involved in conjunction with the fabrication or disposition of the wire-wrapped connections
24
upon the pin contacts
16
.
A need therefore exists in the art for a new and improved electrical connector which can facilitate the simultaneous electrical connection of the telephone lines to the card edge connector, through the intermediary of the new and improved electrical connector, and wherein all electrical connections can be achieved in a solderless manner. In particular, a need exists in the art for a new and improved electrical connector wherein the telephone lines can in effect be electrically connected to the upstanding pins of the card edge connector without the need for wire-wrap connections to be defined between the telephone signal lines and the upstanding pins of the card edge connector. In this manner, all electrical connections can be readily performed in a time-efficient manner comprising minimum expenditures of manpower.
OBJECTS OF THE INVENTION
Accordingly, it is an object of the present invention to provide a new and improved electrical connector.
Another object of the present invention is to provide a new and improved electrical connector which is especially constructed for use in connecting telephone signal lines to a card edge connector.
An additional object of the present invention is to provide a new and improved electrical connector which is especially constructed for use in connecting telephone signal lines to a card edge connector, as well as to permit the attachment of an over-voltage protection printed circuit board to the pin contacts of the card edge connector such that the resulting assembly is especially useful within the telecommunications art.
A further object of the present invention is to provide a new and improved electrical connector which is especially constructed for use in connecting telephone signal lines to a card edge connector, as well as to permit the attachment of an over-voltage protection printed circuit board to the pin contacts of the card edge connector, such that the resulting assembly is especially useful within the telecommunications art, and wherein all electrical connections are able to be achieved in a relatively simple and solderless manner, especially those connections defined between the telephone signal lines and the upstanding pin contacts of the card edge connector.
SUMMARY OF THE INVENTION
The foregoing and other objectives are achieved in accordance with the teachings and principles of the present invention through the provision of a new and improved electrical connector which comprises a plurality of electrical contact members which are provided with insulation displacement contacts at first end portions thereof for connection to the telephone signal wires, and friction contacts at second end portions thereof for connection to the upstanding pin contacts of the card edge connector. The over-voltage protection printed circuit board is disposed atop the distal end portions of the upstanding pin contacts of the card edge connector by means of friction caps or sockets fixedly secured to the printed circuit board. In this manner, it is appreciated that all electrical connections are achieved in a solderless manner.
