An insulation removal contact (not shown) on 2 engages within the assembly and becomes electrically connected to conductor 32, thereby
is in electrical continuity with a discrete portion of the contact termination portion 22, which is arranged for an electrical connection to the outside, ie, to a contact within the plug 12.

The present invention will be explained with reference to FIGS. 4 to 8. Insert 50 is used to accommodate a set of contact elements.

Each contact includes one end of the termination 22 and a central region 54 (FIG. 7) electrically coupling the ends to one end of the insulation stripping contact termination 52. Consisting of On one side thereof (FIG. 5), the insert 5° includes a groove 56 having a first pitch (PI in FIG. 4) spacing corresponding to the pinch of the contact termination 22. Ribs 58 define the groove.

The ribs extend outwardly beyond the bend 60.

On the bottom surface (Fig. 6), insert 5o is pinched 1-1.
A group of grooves 62 is defined with a pitch change corresponding to the required transition from to pitch P2 of the insulated through contact termination 52. At the end opposite the bend, insert 5o

When the plug north 2'4 is retracted into the jack opening 20', the contact termination 22 flexes elastically as it enters electrical engagement with the plug contact.

Although the structure of the jack 14 has been described in Section 5, it will be understood that according to the present invention, the plug 12 can also be assembled in the same manner. However, in the case of the plug 12, the contact termination is used for connection to an external liquid jack contact, so that the plug is in a fixed position in a modular arrangement opposite the elastically deflectable state of the jack contact. It is retained so that it can be inserted into the housing and supported.

When adapted to terminate cables consisting of several conductors, the plug or jack of the present invention includes a housing having contacts arranged in a modular telephone arrangement and having an aperture for receiving an insert member. A contact means is provided which comprises a plurality of contacts having a first end for external electrical connection and a second end of insulation removal type for internal connection with a corresponding electrical conductor. The insert part that holds the contact means and is housed in the housing has contacts arranged at the first and second ends of the common side of the insert part, respectively. 11.
A contact is provided at the first end of the telephone array. The body support element fixes the four bodies in the housing, and places the four bodies in a connected state with insulation removed from the second end of the contact means.

In FIG. 12, connector 78 is shown in its open, unassembled arrangement for use with a 25-pair multi-conductor cable. The connector 78 connects to a base 79 having six compartments, one of which is attached to a base 80. The housing 82 has a latch (third
This corresponds to the jack housing described above, except that 44) in the figure is omitted. A conductive wiring kite or support element 84 is installed in the isolation chamber 80 and includes a set of protrusions 86 through which the conductive wire 88 is connected to the strain relief post 92.
It is routed through the medium heat channel in the folded section 90. During assembly, a downward force is applied to the housing 82 toward the isolation chamber 80 . Electrical contact is made between conductor 88 of cable 94 and contact termination 520 supported by housing 82 as described above.

To facilitate handling and assembly of the connector 78, a semicircular collar 95 is preferably attached to the folding recess 90 as one piece, extending in the 111II+ direction and having the woofer 94 placed therein. It is formed to do so. A detent cable strap 97 or other suitable securing means is wrapped tightly around collar 95 and cable 94 to hold cable 94 in a fixed position relative to connector 78. cable 9
In addition to avoiding direct tension on the cables 9 and 4, the arrangement of the collar/'straps allows the individual conductors 88 to be freely attached to the assembly within the respective isolation chambers 80 and the cables 9.
4 and connector 78 are held together to allow for subsequent electrical connections. In the actual tally shown in Figure 12, 25 pairs of cables are shown, distributed between 8 individual conductors or each of 6 connector compartments1, each half of the connector being connected to posts 96 and 98.

It is positioned by bending and closing the half-circle around t-μ and defines a central channel. At the point of contact, the screw 100 enters the post and engages the thread groove on the inner surface of the post below to provide a securely fixed connector assembly, as shown in FIG. As you can see, the shack housings are arranged in abutting pairs (=
The jack housing and the latches individually associated with it can be dispensed with since the J-keel 1 (designated 12) serves in the assembly as a retainer for the other one.

The connectors of FIGS. 12 and 13 provide a reduction in connections between the modular telephone plug contacts and the 25-pair multi-conductor wire. Current industry standards for this internal IU connection involve as many as five connection interfaces, from cables to telephone jack contacts that can engage plug contacts. Current industry standard practice is for the conductors of telephone cables to be terminated at a secondary plug in a group of strips. This plug (IL interface) connects to a secondary jack defining a second interface. This secondary shack has a dedicated pair-to-conductor third interface therein. The secondary jack output conductor is routed to a splice that has one interface (fourth) with that conductor.
and one interface (fifth) with the contacts of the primary jack providing its output contacts to engage the primary plug contacts.

In the connector of FIGS. 12 and 13, the telephone conductor has only one interface with the modular telephone jack output contact termination 22 for engagement with the modular plug contacts. Thus, the insulation removal contact termination portion 52 is
It is the only interface between the conductor and termination 220 of a multi-conductor cable.

The ribs 122 extend into the plane of FIG. 14, ie, toward the depth of the isolation chamber, to accommodate conductor support cords 124.

and vertical i#i t in the support element 124 (FIG. 16).
A rib is inserted into the elongated hole 126.

The cooperation of the ribs 122 and the side walls of the slots 126 prevents the support element 124 from moving transversely in the direction of the isolation chamber opening 128, but from moving outwardly from the plane of FIG. is not bound, and the space 106 is in an open state during that time.

When assembling a connector using the base of FIG. 14, support elements 124 are inserted into each isolation chamber, sliding over ribs 122. The cable conductor is routed from the fold 116 through the channel 114 to the surface of the support element 1240. The support elements include a first set of re-guides or channels 114 as shown in the subassembly of FIG.

Thereafter, when wiring other conductors to other channels of the channel 138, the 211 bodies are processed without interfering with the four MiJ-wired bodies. This is because the supporting element 124 or its fixed conductors are suspended vertically due to the joint action of the ribs 122 and the elongated holes 126 described above.

25 Equally Large Conductors For adaptability for use with older telephone cables, the present invention provides a connector that includes a base with a pair of isolation chambers separated by a fold, each isolation chamber having a fold. It has an opening at the end farthest from the section and a set of guides for placing the conductors of the multi-conductor cable in a preselected pattern, and the folding section provides a place for placing the conductors outside the isolation chamber. There is. The housing has an insert with contacts residing within each isolation chamber and with a first end of the contacts supported in a modular telephone array. The base can be folded around the folding part, and the housing is fixed in the folded arrangement, and the pair of housings are installed in an abutting relationship.

In particular, in a preferred connector construction, the present invention uses its conductor support member in the form of an insert into the base, the insert defining a set of guides for positioning the cable conductors in a preselected pattern. do. The base and the conductor support rope have cooperative means for increasing the displacement of the conductor support relative to the base.

When assembling terminated 1L cables on-site, arbitrary internal connections can be made without the need for factory-assembled cables, termination sockets, or unnecessary inventory. It is also noted that the connector of the present invention can be assembled without side-by-side fixtures. In other words, the telephone installation name's passing pliers failed to fire]])j, and it was useful enough to realize the sequel.''First of all.

Changes and improvements to the composition of the gods can be made without actually departing from the scope of the A-Z. For example, see FIG. 17.

Instead of placing the connector 78 on the same side, the 11fl jacks are arranged on the same side as shown in Fig. 13, and the base 79 is flat and not folded, so that the individual jacks can be placed on the same side. It is understood that they are provided on opposite sides. The plate side 142 is suitably secured to the l\-spout 9 so as to abut the respective jack housing, thereby holding the jack in place. Suitable openings 144 are provided in the plate side 142 to permit wall mounting of flat connector assemblies or to allow the same connector assemblies to be stacked high.

It is also described in this article as having a 25-pair connector or multiple jacks electrically connected to the conductors of a telephone cable, but it is understood that one plug can be used for one pair if desired. . In particular, the illustrated embodiments and described examples are oriented toward the top and are not intended to be limiting in scope.
