Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connector block support assembly with a support module for interconnecting two or more sets of cables. More particularly, the present invention relates to a connector block support assembly suitable for interconnecting feeder cables, inbuilding distribution cables, telephone equipment and set cables.

In telecommunications systems, the need for interconnections between power feed cables coming from switching centers and embedded power distribution cables, and between telephone set cables and business communication equipment, is increasing over the years. Quick clip connectors to avoid time-consuming and cumbersome wire connections.
clip cannectors) were developed. But besides the act of actually connecting the wires to the connector, the entire organization of the interconnection system remains.

To be truly useful, connector blocks must be organized into an easily accessible and expandable interconnect system. 1973
Caveney et al. in U.S. Pat.
A wire termination and splicing system is disclosed in which a bi-sided, multi-contact connector is rotatably mounted between a pair of rotating mounts. Ellis et al. in U.S. Pat. No. 3,798,587 discloses a connector that engages a protruding receptacle attached to a back panel. The wire to be connected must be placed in the receptacle prior to the connector that engages it.

The system disclosed in the above-mentioned US Pat. No. 3,778,750 must be free standing to allow access to all four sides of the frame, which may be disadvantageous under certain circumstances. Become.

No. 3,798,587 does not teach an organized system for interconnection.

There is a need for an assembly that is easy to install, relocate, and expand. It is an object of the present invention to provide such an improved interconnect assembly.

A feature of the invention is that it is constructed in a simple modular unit that is relatively compact.

When fully installed, the assembly consists of four basic modular components: the support module;
Includes connector block, indicator strip and power distribution ring. The support module is of novel design and holds multiple connector blocks and indicator strips.

The connector block is removably held by a support module such that a first set of wires can be connected to the connector block along one side, and the connector block is removable for connection of a second set of wires. It can be released from and reinserted into the mounting depending on the other possible side. The fitting optionally also provides separate paths for incoming and outgoing cables and for jumper wires, thus allowing for clever placement and easy identification of the cables.

The power distribution ring is used as a spacer between rows of support modules and as a guide for jumper wires.

In accordance with the present invention, an assembly is provided that includes a support module for supporting a connector block;
The support module includes a groove-shaped cross-section base member adapted to removably retain each of a plurality of connector blocks at opposing U sides; and It has fanning apertures on at least one of the two opposite sides for inserting wires for connection to the connector block.

In an assembly according to the invention, the support modules are arranged in rows and adapted to be mounted on a flat surface such as a back panel or wall. The rows are spaced any distance apart to allow the running of jumper wires connecting to the connector block through the fan-shaped openings. Incoming and outgoing cables are preferably connected to the connector block through a gap between the bottom of the module and the connector block.

For organization purposes, two separate sets of modules are used, which are connected to and exited by incoming cables;
Preferably, the other set has modules adapted to be taken in and out by means of outgoing cables.
The interconnection between the two sets is achieved by jumper wires connected to the front side of the connector block after the installation and connection of the supply and distribution cables. Since the jumper wires run freely in the gaps between the module runs and are optionally retained by a distribution ring, they are easy to reorganize.

Typically, the most frequent entry and exit will be to reorganize jumper wires that change the designation of incoming versus outgoing pairs. However, access to change the feed and distribution connections can still be accomplished, although not easily, by releasing the connector block, redirecting it and releasing or changing the connections.

The assembly shown in FIG. 1 includes a support module, generally designated 100, a series of connector blocks 200, a series of indicator strips 300, and a power distribution ring 4.
00, and the latter three are indicated by constant chain lines.

The support module 100 includes a base member 110
and the opposing fan-shaped terminal plate, that is, the support member 12
0 and 120' pairs. Base member 110 as shown in FIG.
20' is a rectangular metal sheet with edges 111 oriented upwardly to form a U-shaped groove-shaped cross-section member to which 20' is attached. Insert appropriate mounting holes and stiffening ridges as necessary into base member 1.
It can be added to 10.

The connector block 200 has an indicator strip 300
(See FIG. 1) between two support members 120 and 120'. There is one marking strip 300 for each of the two connector blocks 200.

Power distribution ring 400 serves the following basic purpose. That is, this means that the adjacent support module 10
0 and provides a gap between adjacent support modules 100 for ease of installation. Although only one power distribution ring 400 is shown in FIG.
Can be used for all four corners of 00.

In the preferred form, the cantilevered spring retainer 121 comprises two spring legs 123 and 124 defining the slot 122, which are interconnected by a web 124' to close the slot 122 at their ends. has been done. To facilitate installation of connector block 200, web 124' has a beveled edge 125.

The indicator strip 300 is held in place by a cantilevered spring retainer 126 having a single leg 127. Slot 128 receives indicator strip 300. Retainer 126 has a beveled leading edge 129 to facilitate insertion.

Support member 1 shown in detail in FIGS. 4 to 9
20 is formed from a thermoset plastic material. Support member 120 is attached to base member 110 by attachment hole 130. The mounting block 131 (fifth block) surrounds the mounting hole from the inside.
(FIG.), into which self-tapping screws are inserted to hold the support member 120 to the base member 110. Upward edge 11 of base member 110
1 (FIG. 2) and outer surface 132 (FIG. 2).
) is recessed to provide accurate alignment of the support member 120 on the base member 110.

Movement of cantilever spring retainer 121 is limited by stop 135, which is supported by legs 136 and 137 (FIGS. 4 and 7). There is one stop 135 for two retainers 121. The fan-shaped opening 138 is connected to the adjacent stop 1.
35 between legs 136 and 137. A wire can be inserted through the gap 139 between adjacent stops 135.

A latching hook 140 (FIG. 5) is provided at each end of support member 120 for cooperation with hook 301 (FIG. 10) of power distribution ring 400. Locking ribs 141 contact surface 302 to lock power distribution ring 400 in place (FIGS. 5 and 11). Alignment grooves 142 are arranged on adjacent support members 120 when multiple modules are used. A similar groove 142 is provided on each latching hook 140 to cooperate with the latching hook 140.

The power distribution ring 400 of FIGS. 10, 11, and 12 is a thermoplastic ring that has a gap 303 at its leading edge for inserting a wire or cable into the ring. Mounting lugs 304 are provided for mounting the ring on the packing board. A groove 305 is provided on the surface of the power distribution ring 400. This is in part to provide a ring with less flexibility, and also to reduce the amount of material needed to form power distribution ring 400.

As shown in FIGS. 13 and 14, the identification strip 300 is an essentially flat extrusion having a slightly recessed front surface 401 to receive an adhesive strip containing the necessary identification information. It is a strip that has been painted.
Ribs 402 run along the front surface 401 at each edge. A stiffening rib 403 is provided on the rear surface 40.

FIG. 15 illustrates one installation of a connector block support assembly for interconnecting multiple insulated wires in accordance with the present invention. Eight support modules 100 are shown in the figure.

The eight support modules 100 are shown in two vertical directions of four support modules 100 each. In the preferred embodiment, each support module 100 supports ten connector blocks 200 and five indicator strips 300. Power distribution ring 400 acts as a spacer between adjacent rows of support modules 100 forming wire channel 410 . Similarly, power distribution ring 40
0' is used as a cable guide for the incoming cable 500.

The incoming cable 500 is connected to the base member 11
0 and the connector block 200 from the rear through a channel formed in the space between the connector block 200 and the connector block 200. Outgoing cable 510 also enters and exits connector block 200 from the rear.

Incoming cables 500 enter and exit the upper group of support modules 600, while outgoing cables enter and exit the lower group of support modules 600'. In this way an organized method of interconnection is possible.

The jumper wire 550 is connected to the wire channel 41
0 and into and out of the support module 100 through the fan-shaped opening 138 from the support module 1
00 extends from the connector block 200 in the upper group 600 to the connector block in the lower group 600'.

Connect to the jumper via the block to complete the connection.

The advantages of the present invention are achieved by a support module having a channel-section base member which can be secured to a flat surface such as a wall. The advantage is that the connector block 200 is fully accessible from only one side of the support module. The support module includes plastic support members 120, 120' on each side of the base member which permit releasability of the connector block 200 by means of a pair of opposing cantilever spring retainers 121.

An important feature of each of the support members is that they include sector openings for insertion of jumper wires for connection to connector blocks. This is,
A unique configuration is provided that allows interconnection of multiple insulated wires as shown in FIG. This arrangement allows, for example, the incoming cable 500 to approach the connector block 200 from above and the outgoing cable 510 to approach the connector block 200 from below, and allows the upper and lower groups 600 The interconnection between connector blocks 200 of
