Description
~L2~59134 \
This invention relates to a telecommunications interface with protector modules, and in particular is concerned with an interface mounted at a subscribers premises for interconnection between the incoming telephone lines and the customers equipment.
It is becoming desirable, and in some instances a requirement, that there be demarcation between the telephone lines of the telephone company and the wiring for telephones at a customers premises. Also, the telephone company at least prefers access to all of its l~nes, up to the demarcation position, at all times. The present invention provides an interface, which can be mounted externally at a customers premises, or at a readily accessible position, and which provides for ready interconnection by providing modular jacks into which modular plugs at the end of the customers wiring can be plugged. The customers wiring can be connected by directly plugging in if modular pl~gs are attached to the wiring, or if spade terminals are on the ends of the conductors of the wiring, an intermediate connection to a short length of cab7e with a plug can be made. The interface is normally in sections, whereby only an outer cover need be removed by the customer for connection~
The invention broadly provides an interface having a base for mounting on a support surface and having terminals for connection of incoming telephone lines, plug-in modules connecting to the terminals, the modules having modular jacks, protector means in the modules, an intermediate cover attached to the base and having apertures for access to the modular jacks and an outer cover extending over the intermediate cover and any plugs entered in the jacks.

The invention will be readily understood by the following description of certain embodiments, by way of example, in conjunction with the accompanyiny drawings, in which:-Figure 1 is an exploded perspective view of one form ofinterface;
Figure 2 is an exploded perspective view of another form of interface;
Figure 3 is a view on the back surface of the base top,`
with contact members removed, of the interface of Figure 2;
Figure 4 is a cross-section on the line IV-IV of Figure 3, with contact members in place;
Figure 5 is a cross-section on the line V-V o~ Figure 3, illustrating a seal;
Figure 6 is a perspective view of the interface of Figure 2 with the intermediate cover on the base; and Figure 7 is a perspective view of the interface of Figure 2 with the outer cover in place.
Figure l illustrates an interface assembly composed of a base 10, an intermediate cover 11 and an outer cover 12. The base is mounted on a support surface, for example a wall, and comprises a back wall 13 with a forward projeoting web 14 along the bottom edge and a further forward projecting web 15 at an intermediate position between the top and bottom of the back wall. The intermediate web 1 has two three-pin plug-in positions at 16 and 17. Each position has two line terminals 18 and a ground terminal 1~. Only one line terminal is shown for clarity, but a line terminal is positioned in each line terminal aperture 20. The ground terminals 19 are formed ~5~3~
at the ends of a continuous strip 21, with the terminals 19 pos~tioned in ground terminal apertures 22. The strip 21 is positioned in a slot or groove 23 joining the apertures 22.
Line studs 25 are inserted into the back wall 13 being connected to the line terminals 18 by means of holes 26 in the terminals. A ground stud 27 is inserted in the intermediate wall 15, making contact with the ground terminal strip 21 via a hole 28 in the strip~ The studs 25 and 27 are threaded, having nu~s and washers indicated generally at 29 for attachment of incoming telephone company lines.
Plugging-in to the positions 16 and 17 on the intermediate web 15 are two modules 35. The modules have forward facing jacks 36 and contain line protection devices. Typical modules are described in co-pending application Serial No. 463,814, entitled "INTERFACE MODULE WITH MODULAR JACK FOR TELECOMMUNICATIONS SYSTEMS", Case PM-1l5, filed 21 September 1984, in the name of the present assignee. The incoming telephone lines are hrought in through holes 37 in the bottom web 14, and then attached to the studs 25, with a ground connection to stud 27. Two sets of telephone lines can be brought in, one set connected to one plug position 16 and the other set connected to plug position 17. However only one set of lines need be brought in and only one plug position used. It is also possible to bring in one set of lines, connected to one plug position, and interconnect conductors positioned to connect in ~he other plug position.
The intermediate cover 11 fits over the base 10. The intermediate cover has a front wall which is in two parts, the lower part 40 being further forward than the upper part 41, In the upper ~ t,,~
~ ~20~3~
part two apertures 42 are provided, through which project very slightly the jacks 36. The front face of the jacks can be flush with the front face of the part 41, or even recessed, provided easy plugging-in if a modular plug is available.
The studs 25 do not extend through the intermediate cover but are contained within the lower part of the intermediate cover. In the example, stud 2-/ extends through the intermediate cover, via hole 43 at the upper edge of the lower part 401 Nut 44 holds the intermediate cover in place. A web 45 extends forward at the bottom edge of the intermediate cover and slots 46 provide for entry of customers wiring.
Normally, the base is mounted on the support surface, the telephone companies lines connected to the studs 25 and 27 and the intermediate cover placed in position and fastened. The customer does not need access behird the intermediate cover as the customers connection is by plugging in to the jacks 36 accessible through the apertures 42. If the customers wiring ends in modular plugs then these are inserted directly into the jacks 36. If the customers wiring ends with spade terminals, studs can be inserted into bosses 47 on the front of portion 40. The spade terminals are first connected to the studs and then a short length of interconnect oable also attached at one end to the studs, with the other end of the cable having a plug. This is illustrated in Figure 6.
Once the customers wiring has been connected, to one or both jacks 36, the front cover 12 is put over the intermediate cover.
The front cover is held in position by a hollow screw 48 which screws on to the end of the stud 27.

Figures 2 to 7 illustrate an alternative form of interface having a different type of module. In the example of Figure 1, assuming the back wall of the interface assembl~ is vertical, the modules 35 plug in vertically, while the insertion of plugs into the jac~s 36 is horizontal. That is the insertion direction for the jacks is normal to the insertion direction of the module. In the arrangement of Figures 2 to 7 the modules insert in the same direction as the insertion into the jacks, this usually being horizontal.
As particularly seen in Figure 29 the interface assembly comprises a base having two parts, a base bottom 50a and a base top SOb, referred to generically as the base 50; an intermediate cover 51; and a front ~r outer cover 52. The base is mounted on a support surface, normally a wall and has two three-pin plug-in positions 53 near the top edge. Below the plug-in positions is a row of bosses 54 having bores 55, into which are mounted threaded studs 56. The rear ends of the studs 56 are connected to suitable contact members which carry terminal positions posi-tioned behind the terminal apertures 57. The incoming telephone line conductors, Tip and Ring, are attached to the front ends of the studs 56, and thus via the contact members to the terminals in apertures 57. A further stud 58 extends through a boss 59 and is connected to a ground contact member which has terminal positions behind apertures 60. A plug in module 61 can be positioned at the positions 53 and 54. The modules have forward facing jacks 62.
Figure 3 is a view on the rear or back surface of the base top 50b. The terminal apertures 57 are shown, as are also the ground apertures 60. The studs 56, Figure ~, pass through the base ~2~5~34 , ~
top, via holes in the bosses 55. Nuts on the studs sit in hexagonal portions of the bores 55 and carry contact members which extend up to the terminal apertures 57. The contact members are positioned in channels 65 defined on the back surface of the base top. This is seen clearly in Figure 4 where a contact member 80 is shown positioned in a channel 65. At its lower end the contact member is attached to a stud 56 and at its upper end the contact member has a formed terminal position 81. Somewhat similar is a transverse channel 82 at the top of the base top. A bare 83 in the boss 59 (Figure 3) communicates with this channel and a contact ~,ember extends along the channel being attached to a stud 58 extending through bore 83. At each end the contact member would have a formation similar to ~hat at 81 for contact member 80. Contact blades on a module 61 pass through the apertures 57 and 60 and make contact with the terminal formations on the contact membersD
The telephone company lines can be brought in between pairs of guide and locating ribs 63 at the bottom of the base. As an alternative they can be fed through from behind the base through apertures 64. Only one pair of lines need be connected, or two pairs. ~f one pair only is brought in only one module may be used9 or both modules used by suitable interconnection~
At the lower edge of the base there is a forwardly extending rib 85 which has a laterally extending slot 86 therein. In the slot, on assembly of the interface unit, a strip of elastomeric material is positioned, as shown at 87 in Figure 5. A similar arrangement of a rib, this time extending rearwardly, is pravided at the lower edge of the intermediate cover 51. This rib also has a ~IL2~
slot therein. On assembly of the intermediate cover to the base, the elastomeric material 87 extends into the slot in the intermediate cover. When a telephone line is brought in between a pair of guide and locating ribs 63, the elastomeric material is deformed at that position. Small semi-circular grooves are formed in the Front edges of the ribs on the base and intermediate cover to accommodate telephone lines. Alternatively, a strip of elastomeric material can be positioned in each slot and arranged to abut on assembly of the intermediate cover to the base.
The intermediate cover ~1 is fitted over the base 50, as seen in Figure 6~ with the jacks 62 projecting into apertures 65 in the intermediate cover. The studs ~6 do not extend through the intermediate cover, being contained within it. The ground stud 58 is accessible through the intermediate cover~ a hollow captive screw 66 engaging on the outer end of the stud 58 and holding the intermediate cover in place.
A row of bosses 67 near the bottom of the intermediate cover provide for mounting of studs, not shown in Figure 2, for use when the customers wiring does not end in a modular plug. This is as in Figure 1. The customers wiring is brought in, via slots 68 in a b~ttom web 69 of ~he intermediate cover. If the wiring ends in a plug it is connected directly to the jack by insertion of the plug.
If the wiring has spade terminals, then they are connected to studs in the bosses 67, and a short cable with spade terminals at one end and a plug at the other is used as an interconnection. This is illustrated in Figure 6, the customers wiring indicated at 70 and 71.
The wiring at 70 has spade terminals which are connected to studs 72.
~;~VS~3~
, A short cable 73 is connected at one end to the studs 72 and has a plùg 74 at the other end inserted into one jack 62~ The wiring 71 has a plug 75 at its end which is inserted directly in the other jack 62. A further stud 76 is mounted in a boss 77 and serves to connect the ground conductor of the wiring 70 to the ground conductor of -the cable 73. The incoming telephone company lines are indicated at 78.
A separate ground conductor is shown at 90.
The front or outer cover 52 fits over the intermediate cover 51, and is held in place by a screw 79 which engages in a boss 80 on the intermediate cover. Normally, the customer only needs to remove the outer cover to connect his wiring. Access behind the intermediate cover is normally only by telephone company personnel.
The modules 61 generally contain protectors. The completely assembled interface, with front or outer cover in place, is illustrated in Figure 7. Figure 7 illustrates an alternative arrangement of incoming telephone company lines. In Figure 7 a single four-conductor line is indicated at 78. The separate ground conductor is shown at 90.
This invention relates to a telecommunications interface with protector modules, and in particular is concerned with an interface mounted at a subscribers premises for interconnection between the incoming telephone lines and the customers equipment.
It is becoming desirable, and in some instances a requirement, that there be demarcation between the telephone lines of the telephone company and the wiring for telephones at a customers premises.
