Referring now, in detail, to the various views of the drawings and in particular to Figures 1 to 3, there is illustrated a protective module for the voltage rise of the present invention, which is designated, generally, with the number 10. to protect the telecommunications equipment from the voltage surges that occur in the tip and / or ring conductors of the transmission lines connected to it. The surge protector module 10 is used to protect sensitive telecommunications equipment from up to 4 pairs of cables (8 conductors) of the transient energy drivers for each pair of cables. The surge protector module is uniquely designed to comply with the maximum transmission loss allowed due to the internal wiring of the structure and connectors according to the TIA specification for Category 5 (specification No. 568A for connectors). The surge protector module 10 has a substantially box-shaped configuration, although other forms of construction can be used. The surge protector module includes a molded housing 12 that is made of a suitable plastic material, such as a non-polycarbonate material and the like, comprising a base member, which engages 14, and a cover member 15. The cover member 16 can be suitably secured to the base member 14, in any number of conventional means known in the art. The base member 14 has a generally rectangular configuration and has a flat surface that conforms to the sub-assembly of the printed circuit board 18. The cover member 16 has opposite side walls 20 and opposite end walls 22, respectively . The end and side walls 20 and 22 define a cavity 24 for receiving and housing the sub-assembly of the printed circuit board 18 mounted on the base member 14. The sub-assembly of the printed circuit board 13 includes a printed circuit board. printed circuit 26, a plurality (4) of surge protection devices of the circuit 28a-28d, an input connector mechanism 30, an output connector mechanism 32 and a ground shield 34. The mechanism of the input conductor 30 is disposed, preferably adjacent to the upper end of the printed circuit board 26, and the mechanism of the output connector 32 is disposed, preferably adjacent to the lower end of the printed circuit board 26. The mechanism of the input connector can be any number of commercially available connectors, and well known in the art. For example, for telecommunications equipment the input connector mechanism preferably comprises a pair of AT &amp terminal connectors.; T 110 36, each has a 4 position so that up to 4 pairs of incoming telephone lines of a common telephone cable (not shown) can be placed together from each exit to the central office of the service area or from the distribution panel inside the building. Similarly, the output connector mechanism can be a number of different types and is preferably a normal modular connector 38 which is referred to as an 8-position RJ-45 connector, to terminate a telephone line cable with 4 pairs of cables . The modular connector 38 is adapted to receive a normal modular connector that is connected to an individual telephone equipment. The mechanism of the input and output connector has easy and fast mechanical connections for four sets of voltage protection devices in the circuit 28a-2d located on the printed circuit board 26. In order to facilitate the operation of the device protector for the voltage rise in the circuit 28a-28d arranged on the printed circuit card 26, as well as to provide a discharge path to ground for the voltage surges in the power and in the transient, the ground wire 40 has one end operatively connected to the protective devices and the other end connected to the bus, terrified, external common (not shown). The ground cable 40 is preferably arranged so that it extends through one of the side walls 20 of the housing 12. The present invention relates to the structure of the module for the protection of voltage surges 10 containing four sets of surge protection devices in the circuit 28a-28d mounted on the printed circuit board 26 together with the method of manufacturing the plurality of conductive tracers on the printed circuit board in order to comply with the TIA specification for Category 5. A schematic circuit diagram of one of the sets of surge protection devices in circuit 28a-28 is illustrated in Figure 4 of the drawings. Since each set of circuit protective devices is the same in their construction, they believe that it is sufficient to describe only one of them in detail. As can be seen in Figure 4, the protective devices of the voltage rise in the circuit 28a comprises four banks 42, 44, 46 and 48 of rectifying diodes and a pair of voltage suppressors 50, 52. The input side of the protective device 28a is connected between the wires of the incoming telephone transmission lines applied through the terminal of the input tip 54 and the input ring terminal 56 defining an unprotected side. The output side of the protective device 28a is connected between the two cables of the individual telephone equipment to apply protection through the output tip terminal 58 and the output ring terminal 60 defining a protected side. Each of the four banks 42-48 of diodes comprises three (3) low capacitance diodes connected in parallel. The first diode bank 42 is formed with three DI diodes connected in parallel with their common cathodes connected together at the node A and also connected to the first lead conductor. The first lead conductor in the present invention takes the physical form of a tip or a first conductor tracer 62. The common anodes of the DI diodes are also connected together B and further they are joined to the second lead conductor. The second lead conductor has the physical form of a second conductor plotter 63. The second bank 44 is formed with three diodes D2 connected in parallel with their common cathodes connected together at node C and further linked to the third lead conductor. In the present invention, the third lead conductor has the physical form of a third conductor or ring tracer 64. The common anodes of the diodes D2 are also connected together at the node B and the second conductor tracer 63. Similarly, the third bank 46 is formed with three diodes D3 connected in parallel with their common anodes connected together at the node D and further connected to the first conductor plotter 62. The common cathodes of the diodes D3 are also connected together at the node E and also they join the fourth leading driver. The fourth lead conductor takes the physical form of a fourth conductor tracer 65. The fourth bank 48 is formed with three diodes D4 connected in parallel with their common anodes connected together at the node F and further linked to the third conductor tracer 64. The common cathodes of the diodes D4 are also connected together in the node E and in the fourth conductor plotter 65. Each of the diodes D1-D4 in the respective banks 42-48 may be similar to the type 1N5408 or CSS02003 having a low capacitance. The first voltage suppressor 50 has a first end connected to the second conductor plotter 63 and its other end is connected to the ground source GND via a grounding conductor. In the present invention, the ground conductor leads to the physical form of a common elongated ground conductor zone 66. Similarly, the second voltage arrester 52 has its end connected to the fourth conductor tracer 65 and its other end also connected to the ground conductor. the conductive zone, common to ground, elongated 66. Each of the voltage suppressors 50 and 52 can be formed with a silicon avalanche suppressor (SAS), didactor, gas tube, or Zener diode. In the preferred embodiment, the voltage suppressors 50, 52 are silicon avalanche suppressors similar to the 1.5KE type. The manufacturing technique for conductor plotters 62-65 on the printed circuit board for mounting the surge protector 28a is best understood by reference in Figures 5 to 7 of the drawings. In order to comply with the TIA specification for Category 5, the inventors have determined that the impedance circuit (series) of the surge protective device should be made as small as possible, so that the width is extended band of the transmission line connected to it and to minimize attenuation. In other words, the series of resistance and inductive reactance at the tip of the first conductor tracer 62 and in the third conductor or ring tracer 64 must be made very small. It has been found that this can be achieved by increasing the width of the conductor plotters 62 and 64, keeping the length of these tracers as short as possible, and keeping the conductor plotters relatively straight. In addition, the inventors determined that line-to-line (parallel) impedance must be made as long as possible, in order to extend, in the same way, the width of the band of the transmittance lines connected to it. In other words, the line-to-line capacitance between the lead conductor plotter 62 and the ring conductor plotter 64 must be made very small. This can be achieved by adding low capacitance diodes (ie DI, D4) in series with capacitance due to voltage suppressors 50, 52. While each bank of diodes is shown with three diodes, they can have any number of diodes dependent on the amount of capacitance that is added, as well as the amount of current for the voltage rise that is experienced. As can be seen from Figures 5 to 7, the tip driver plotter 62 was located on the upper side 68 of the printed circuit board 26 and that the ring driver 64 was placed on the lower side 70 of the card of the printed circuit. The conductor plotters 62 and 64 are placed, preferably as close as possible to each other, but not so that they overlap each other. If the distance between the plotters 62 and 64 is very far apart, an excessive amount of inductive reactance will occur. If the conductor plotters 62 and 64 have to overlap each other, an excessive amount of capacitance reactance will occur. In each instance, the width of the guard band will be reduced. it should be apparent to those skilled in the art that the criterion established above with respect to the conductor plotters 62 and 64 for the first set of voltage surge protective devices 28a applies equally, as well as to the corresponding plotters for the second, third and fourth voltage surge protective devices 28b-28d. Accordingly, the pattern of the conductor plotters 62 and 64 for each set of surge protection devices is formed on a printed circuit board 26 as illustrated in FIGS. 5 through 7, so that they cooperate with each other. the electrical components mounted on it, with the aim of complying with the TIA specification for Category 5.
In addition, the inventors have determined that in order to meet the crosstalk criterion (NEXT) for Category 5, the torque-to-torque impedance must be increased. In other words, the capacitance between the adjacent pairs of the conductor plotters 62, 64 for each set of surge protection devices must be reduced to a small value. It was found that this was achieved by increasing the distance between the adjacent pairs. In addition, by providing a ground shield 34 between the second and third pairs of conductor plotters, it was found that crosstalk between them is improved. In Figure 8, a second alternative embodiment for the sub-assembly of the printed circuit board is shown. It can be appreciated that the sub-assembly of the printed circuit board 118 is substantially identical to the sub-assembly of the printed circuit board 18 of Figure 2, except that two additional ground shields are provided. A second ground shield 34a is disposed between the first and second adjacent pairs of conductor plotters. A third ground shield 34b is disposed between the third and fourth pairs of conductor plotters. In Figure 9, a third alternative embodiment for the sub-assembly of the printed circuit board is shown. It can be seen that the sub-assembly of the printed circuit board 218 is substantially identical to the sub-assembly of the printed circuit board 18 of Figure 2, except that the ground shield 34 was replaced by an elongated slot 34d defining an air gap introduced between the second and the third pair of adjacent tracers. Since the air has a lower dielectric constant than the material used to form the printed circuit board, the dielectric constant between the second and third pairs of conductor plotters will be reduced and thus, the capacitance will also be reduced, so that it is improved the crosstalk between these. Thus, from the above detailed description, it can be seen that the present invention provides a voltage surge protector module for protecting telecommunications equipment and the like from power surges that include a two-piece fitted housing that receives a printed circuit board for mounting four sets of surge protection devices, an input connector mechanism connected to the exposed side and an output connector connected to the protected side. The protective module of the voltage rise is characterized by a series of small impedances and a large line-to-line impedance. The printed circuit board has a unique pattern of conductive tracers for mounting the electrical components of the protective devices so that it complies with the specification for Category 5. In Figure 10, a second embodiment of a protective device is illustrated. the voltage rise 28b defining a hybrid circuit of the present invention. All the elements of the circuit in the second embodiment of the invention of Figure 10 are the same as those used in the protective device of Figure 4, with the addition of a second voltage suppressor of two tubes for gas connected in series GTl and GT2. In particular, the two gas tubes connected in series GTl and GT2 are also connected between the input telephone transmission lines applied through the input tip terminal 54 and the input ring terminal 56. In addition, the tubes of gas are connected in parallel with the four banks 42-48 of the rectifying diodes D1-D4 and a pair of voltage suppressors 50, 52. The junction of the gas pipes is coupled to a potential ground GND. In operation, after the occurrence of a voltage and power surge through the tip and ring terminals 54 and 56, the first voltage suppressor 50, 52 will initially block the voltage rise to ground, in just a few nanoseconds. Then, the second voltage suppressor, formed from the GTl, GT2 gas tubes, will subsequently turn on and divert the balance from the voltage rise to ground. As a result of this, when the protective device 28b is used in conjunction with the manufacturing technique for conductor plotters 62-65 on the printed circuit board 26 it will meet the AIA 568A specification for category 5 and will produce a response over a period of time. very short time, of just one nanosecond together with the ability to handle the highest voltage surges. In Figure 11, there is illustrated a third embodiment of a surge protector in a circuit 28c defining a Category 5 gas tube protector. The surge protector 28 c consists of two gas tubes connected in series at the two input tip terminals 54 and the output tip terminal 58. The other end of the gas tubes are connected to the two input ring terminals 56 and the output ring terminal 60. The connection of the gas pipes is connected to GND potential ground. Since the capacitance of the gas tubes is relatively low in a range from 1 to 2 nanofarados, the need for banks of diodes 42-48 has been eliminated, with the objective of additional capacitance. As a consequence, when the protective device 28c is used in conjunction with the manufacturing technique for the conductive tracers 62-64 on the printed circuit board 26, it will comply with the AIA 568A specification for category 5, but will produce a shorter response time (i.e. a few microseconds) than the first voltage suppressor 50, 52. While what has been described and illustrated as preferred embodiments of the present invention has been described and understood, those skilled in the art will understand that changes can be made and modifications, and the equivalents can be replaced by elements of these without departing from the true scope of the invention. In addition, many modifications can be made to adapt a particular situation or material to the teachings without departing from the central scope of the invention. Therefore, it is intended that this invention not be limited to a particular embodiment presented as the best modes considered for developing the invention, but that the invention will include all embodiments that are included within the scope of the appended claims.
