Abstract
Abstract The specification describes a front-facing terminal block 10 for mounting to a support bracket 12 that is affixed to telecommunication main distribution frame for interconnecting telephone equipment. The front facing terminal block 10 has a generally rectangular housing 14 with a top panel 16, rear panel 18, bottom panel 20 that extend between side panels 22 and 24 defining a front opening 28. A terminal field assembly 38, having an insulative panel 40 with an array of electrical terminal pins 50 formed therein, is pivotally mounted adjacent the forward end of the housing 18 for pivotal movement from a down position projecting into the front opening 28 to an upward position away from the front opening 28. The terminal pins 50 connected by wires to either 50-pin female receptacle ribbon connectors 98 or 64-pin female receptacle ribbon connectors 104 or a combination of the two. Such connectors 98 and 104 are adapted to be mounted within 50-pin apertures 98 and 64-pin apertures 88 that are interconnected and overlapping to form a generally enlarged rectangular multiple connector opening 76 illustrated in FIGS. 4 and 5.

Claim 1
Independent Claim
316 words
A front facing connectorized terminal block for mounting to a support bracket affixed to the telecommunication main distribution frame, comprising: a terminal block housing having a rear panel that is releasable mountable to the support bracket for supporting the connectorized terminal block on the main distribution frame; the terminal block housing having a bottom panel extending between the side panels forward of the rear panel for receiving and supporting a plurality of multi-pin ribbon connectors; a terminal field assembly having an insulative panel with an array of electrical terminal pins having first extending from a front face of the insulative panel and second portions extending from a rear face of the insulative panel in which the second portions are adapted to be electrically connected to a plurality of multi-pin female ribbon connectors; said terminal field assembly having a fanning strip adjacent the front face of the insulative panel for routing cross connecting electrical wires to the first portions of the array of electrical terminal pins; said terminal field assembly being operatively pivotally mounted to the housing for movement between a down pivot position in which the insulative panel projects into the front opening of the housing with the first portions of the array of electrical terminal pins projecting forward for direct frontal access and an up pivot position in which the insulative panel is removed from the front opening of the housing with the second portions of the array of electrical terminal pins projecting forward for direct frontal access; a front cover pivotally attached to the housing and operative to enclose the front opening when the terminal field assembly is in the down pivot position; and connector mounting means associated with the housing bottom panel capable of receiving and supporting both 50-pin female miniature ribbon connectors and 64-pin female miniature ribbon connectors in a downward orientation to connect to respective upward oriented male miniature ribbon connectors.

A front facing connectorized terminal block for mounting to a support bracket affixed to the telecommunication main distribution frame, comprising: a terminal block housing having a rear panel that is releasable mountable to the support bracket for supporting the connectorized terminal block on the main distribution frame; the terminal block housing having a bottom panel extending between the side panels forward of the rear panel for receiving and supporting a plurality of multi-pin ribbon connectors; a terminal field assembly having an insulative panel with an array of electrical terminal pins having first extending from a front face of the insulative panel and second portions extending from a rear face of the insulative panel in which the second portions are adapted to be electrically connected to a plurality of multi-pin female ribbon connectors; said terminal field assembly having a fanning strip adjacent the front face of the insulative panel for routing cross connecting electrical wires to the first portions of the array of electrical terminal pins; said terminal field assembly being operatively pivotally mounted to the housing for movement between a down pivot position in which the insulative panel projects into the front opening of the housing with the first portions of the array of electrical terminal pins projecting forward for direct frontal access and an up pivot position in which the insulative panel is removed from the front opening of the housing with the second portions of the array of electrical terminal pins projecting forward for direct frontal access; a front cover pivotally attached to the housing and operative to enclose the front opening when the terminal field assembly is in the down pivot position; and connector mounting means associated with the housing bottom panel capable of receiving and supporting both 50-pin female miniature ribbon connectors and 64-pin female miniature ribbon connectors in a downward orientation to connect to respective upward oriented male miniature ribbon connectors.
Claim 3
Dependent Claim
37 words
The front facing connectorized terminal block as defined in claim 1 wherein the connector mounting means includes two sets of mounting apertures, one set for receiving the 50-pin connectors and the second set for receiving the 64-connectors.
Claim 4
Dependent Claim
33 words
The front facing connectorized terminal block as defined in claim 2 wherein the mounting apertures of the two sets are interspersed to enable the 50-pin connectors to be interspersed with the 64-pin connectors.
Claim 5
Dependent Claim
54 words
The front facing connectorized terminal block as defined in claim 1 wherein the connector mounting means includes a plurality of 50-pin connector apertures formed in the bottom panel to receive a plurality of 50-pin connectors and a plurality of 64-pin connector apertures formed in the bottom panel to receive a plurality of 64-pin connectors.
Claim 6
Dependent Claim
33 words
The front facing connectorized terminal block as defined in claim 4 wherein each of the 64-pin connector apertures have a length greater than a corresponding length of each of the 50-pin connector apertures.
Claim 7
Dependent Claim
23 words
The front facing connectorized terminal block as defined in claim 4 wherein the 50-pin connector apertures are interspersed between the 64-pin connector apertures.
Claim 8
Dependent Claim
35 words
The front facing connectorized terminal block as defined in claim 4 wherein the 50-pin connector apertures and the 64-pin connector apertures are interconnected to define a combined in the bottom panel to receive the connectors.
Claim 9
Dependent Claim
36 words
The front facing connectorized terminal block as defined in claim 7 wherein the enlarged opening has two opposing mounting side edges that are serrated with 50-pin mounting tabs extending into the enlarged opening at preselected intervals.
Claim 10
Dependent Claim
38 words
The front facing connectorized terminal block as defined in claim 8 wherein the inward projecting 50-pin mounting tabs have mounting holes formed therein to enable 50-pin connectors to be mounting between corresponding mounting tabs of the opposing edges.
Claim 11
Dependent Claim
