FIELD OF THE INVENTION The present invention relates to crosslinking assemblies, and more particularly to jack assemblies for digital crosslinking systems.

The digital cross link system (hereinafter referred to as DSX) provides a line that interconnects two digital transmission lines.

Devices for DSX are usually installed in one or more frames or compartments at the telephone central control station. The DSX device also provides a jack to access the transmission line.

DSX jacks are known and include a number of spring contacts that accept a tip-ring plug. The jacks are gathered as a copopulation in a common housing mounted on the frame. Typically the jack is connected to a lead terminal pin mounted opposite the plug access hole in the housing.

Conventional DSX devices typically required practical space allowing the operator access to the rear of the housing to perform the required cross-connect wiring. Also, the conventional device was inflexible in shape, and failed to provide any important electronic circuitry such as signal augmentation network between the spring and the terminal pin.

The present inventors have thought that the conventional electronic component surface mounting technique can be embodied as a jack design that increases the adaptability of the DSX jack electronics and network. It was also contemplated that the jack design could include a means for the operator to perform the required cross-connected wiring without having to access the rear end of the assembly. Finally, we considered a design that would allow for greater user flexibility.

A jack assembly is described according to a preferred embodiment of the present invention. The assembly includes a mount having a plurality of exposed electrical contact members and a plurality of jacks with means for releasably attaching each jack to the mount. Each jack includes a jack body of an insulator. The body has an interior chamber in communication with a number of bores extending through the front wall of the body. The bore is sized to receive a tip-ring plug of predetermined dimensions. The plurality of conductive spring contacts are disposed in the chamber with the first end fixed to the body. The circuit board has means for connecting the circuit board to the body. The circuit board includes a network having a plurality of first circuit contact points arranged to be in electrical contact with the spring contact when the circuit board is attached to the nonconductive body. The circuit board also includes a plurality of first circuit contact points arranged to make electrical contact with the exposed electrical contact members of the mount when the jack is attached to the mount.

The jack assembly of the present invention will now be described with reference to the preferred embodiments with respect to several figures in which like parts are shown with like numerals throughout.

In FIG. 1, the jack assembly includes a housing or jack mount 10 and a plurality of jacks 12. In a preferred embodiment eight jacks 12 will be associated with each jack mount 10. Since each jack 12 is identical, it will be sufficient to describe one jack. In FIG. 1 only two jacks 12 are shown to facilitate the description of jack 12 and jack mount 10.

Similarly, the intermediate post 42 also has a protruding member 149 having a hole 169a arranged to align with the hole 169. With the circuit board 18 properly aligned with the body 14 and with the holes 166-169 aligned with the holes 166a-169a, the rivets 199 (shown in FIG. 1) are aligned. The circuit board 18 can be firmly fixed to the body 14 through the hole.

la. Lead sheath terminal pin

As shown in FIG. 1, five conductor sheath terminal pins 141 to 145 protrude through the front wall of the intermediate post 42 and are flat in a plane generally parallel to the spring contacts 124 to 138. Arranged as. The wire sheath terminal pins 141 to 145 have a 90 ° bend ending at the first ends 141 'to 145' facing the circuit board 18. As shown in FIG.

The plurality of third circuit board contact points 191 to 195 are aligned to receive the first ends 141 ′ to 145 ′ of the conductor sheath terminal pins 141 to 145. The first ends 141'-145 'are welded to the contact points 191-195. Since the circuit board 18 is flat and the circuit contacts 150 to 164 are in substantially the same plane as the contact points 191 to 195, the first ends 141 'to 145' of the terminal pins 141 to 145 are It is generally coplanar with the exposed tip of the trailing tab of the spring contacts 124-138.

hemp. network

The circuitry of circuit board 18 includes a number of circuit paths 500 that connect various combinations of contact points 150-164,601-612,191-195. The network includes resistors and other circuit mounting components 502 to provide known DSX jack functionality.

The circuitry of the circuit board 18 is schematically shown in FIG. As shown in FIG. 13, the network is adapted to receive an OUT signal having a tip line and a ring line respectively connected to one of the contact points 601 to 612. In the state where the plug is not inserted into the jack, the signal is transmitted to the terminal pins 142 and 143, and may be cross-connected to another jack as described below.

As schematically shown in FIG. 13, only seven contact points 601 to 612 are required for conventional DSX jack operation. The choice of seven is a matter of choice as long as certain seven are known and are in constant use. The remainder of the contact points 601-612 can be used for the signal augmentation function as described below. Seven DSX contact points include OUT signal tips and ring contacts (OUT, T and R), IN signal tips and ring contacts (IN T and R), sleeve ground contact points (GND), LED ground contact points (LG), and LEDs (118) The energized contact point (-48V) for light emission.

The cross connection from another jack arrives as an IN signal from the cross connecting lead terminal pins 144 and 145. With the plug not inserted into the jack, the signal is the output at IN T and IN R. In FIG. 13, the letters "R" and "T" represent "ring" and "tip", "GND" represents "ground", "TN" represents "standard tip", and "RN" represents " Standard ring ", and" TL "stands for" tracking light ".

By inserting the plug into the IN bore 106, the IN signal from the cross-connected jack can be cut off and the signal from the inserted plug can be output at points IN T and IN R. Similarly, by inserting the plug into the OUT bore 105, signals from points OUT T and OUT R can be interrupted and transmitted to the tip and ring contacts 110, 112 of the plug.

Frequently, it requires that the signal be monitored on the OUT line without blocking the OUT line signal. To accomplish this, the plug is simply inserted into the monitor bore 104. If this occurs, the ring contact 134 is transferred as shown in FIG. When the ring contact 134 has been transferred, the sleeve 146 acts on the spring contact 135 to electrically contact the contact point 135b and the contact point 136b of the spring contact 136. As can be seen in FIG. 13, the electrical connection of the spring contacts 134, 136 connects the LED circuit to ground, thereby causing the LED to emit light. Circuit mounting component 502 (including integrated circuit IC) controls the light emission of the LED. Examples of LED light emission control networks can be found in US Pat. No. 4,618,194.

In addition to activating the LED, inserting the plug into the monitor bore 104 also grounds the tracking light line TL at the lead terminal pin 141. This causes the LED to fire at the jack where the current jack is cross-connected.

It will be appreciated that the above description of DSX jack network and its electronic construction is known in the art and does not form part of the present invention. The above description is merely an illustration to aid in understanding the present invention.

In the described device, the operator can connect to the mounting 10 by pulling the cable from the frame chamber 321 and passing the cable between the horizontal support plates 324, 326. The conductors from the cable may be individually connected to the conductor sheath terminal pins 302 extending from the rear wall 300.

To assist the conductor control, the conductor mounting bracket is connected to the rear wall 200. The mounting bracket 400 is shown in FIGS. 15 and 18 and basically constitutes a first member 401 connected to the rear wall 200 with a number of screws 402. The first member 401 has a vertical surface 401 ′ spaced from the pin 302. The flanged u-shaped bracket 403 is connected to the first member 401. After terminating the lead at pin 302, the operator can simply wind the cable around the bracket 403 to ensure that the cable is not pushed or otherwise to prevent the lead from peeling off the pin 302. .

With the pins 302 of the mount 10 fully connected, the mount 10 is inserted into the frame 320 while the clips 340 are received in the holes 330 and 336 to thereby frame the mount 10. It is determined by 320. When the mounting table 10 is installed, the inclined surface 341a engages with the tab 328, and the tab 340 is bent to pass under the tab 328. When the clip 341 arrives at the hole 330, the clip 341 is inserted into the hole 330 and the clasping surface 342 acts on the tab 328 to hold the clip 341 to the hole 330. do. Similarly, the lower tab 340 locks the mount 10 to the second horizontal support plate 326.

The operator installs each jack 12 by capturing the jacks and pressing the tabs 34 and 36 towards each other. The operator aligns the rails 20 and 22 with the slots 204 and 206 and slides the jack 12 into the mount until the locking blocks 30 and 32 are aligned with the holes 205 and 207. Once this alignment is complete, the operator can release the tabs 34 and 36, and the locking blocks 30 and 32 are pushed into the holes 205 and 207 by the completion of the members 26 and 28 to push the jack 12. It is locked in the mounting table 10.

When jack 12 is inserted into mount 10, a number of second circuit board contact points 601-612 are moved to make electrical contact with clip 303 in slot 208. Therefore, electrical communication is made between the lead terminal pin 302 and the required contact points 601 to 612.

The operator performs the required cross-connect wiring by terminating the lead at the conductor sheath terminal pins 141 to 145 and cross-connecting it to another jack or another device. A lead terminated at pins 141-145 can pass through hole 370 into trough 349a to lead control clip 347.

As can be seen from the above description, the operator does not have to approach the rear of the frame to make the cross connection wiring. In fact, the operator never goes to the rear of any wiring frame. When desired to change the wiring at the rear of the mount 10, the mount 10 can be simply removed to achieve rewiring at the front of the frame. Once the mount 10 is connected and installed, all cross connect wiring is done at the front wall of the frame. Once the jacks 12 have been so installed and cross-connected, the jacks 12 are conventional for DSX jacks in that the plugs 108 can be inserted into the IN, OUT or monitor bores as required for all intended purposes. Can be used for this purpose.

In a telephone company, telephone lines are primarily connected from the DSX compartment to other parts of the signal consolidation facility. A common signal intensifier is a loss-correcting iterator network that may otherwise obscure the digital signal. In the prior art the operator would connect the leads from the DSX compartment to the compartment of the repeater. Using the present invention, the jack 12 can be manufactured to have a circuit board 18 that includes circuit elements to achieve repeater functions. Thus, jack 12 may perform cross-connect and repeater functions in a single piece of equipment. As shown, jack 12 includes twelve contact points 601-612. Only seven points are required for conventional DSX functionality. The rest can be used for signal enhancement.

In case additional circuit components are added to the circuit board 18, it is desirable to add slits or holes for air circulation to the top wall 201, the back wall 200 and the bottom wall 202.

From the above description of the invention it has been shown how the object of the invention has been achieved in a good way. The present invention provides a jack assembly that does not require access to the rear of the DSX frame, and provides an efficient cross connection since cross connection terminals are provided in front of the jack. The shape also provides additional functionality to the adaptability and DSX jacks. The frame, together with the assembly, provides efficient lead control.

Although the foregoing description describes the present invention as a preferred embodiment, it will be understood that the present invention includes all modifications and equivalent shapes. Accordingly, the scope of the present invention is to be limited only by the appended claims.
