referring now to the drawing , fig3 through 9 depict the present invention , wherein fig3 a through 4 depict the operative principles , fig5 and 6 depict a preferred embodiment of the present invention , and fig7 through 9 depict an alternative preferred embodiment of the present invention . at fig3 a and 3b , a pair of electrical connectors 100 are shown in the form of single terminal mating male and female connectors 102 , 104 . the mutually closest tips 102 t , 104 t of the terminals 102 , 104 are separated by an air gap g which is within the terminal proximity zone z , the length of the zone being that which is most prone to involve electrical arcing and may vary depending , for example , upon circuit load and atmospheric conditions . an electrical arc 106 leaps between the terminals 102 , 104 . however , because a magnet 108 provides a magnetic field b in the terminal proximity zone z , as the electrons span the air gap g between the tips , the magnetic field subjects them to a force f which is perpendicular to their direction of movement . accordingly , the electrons cannot take a most direct path ( straight line ) between the tips 102 t , 104 t , but rather must take a curved path ( see fig3 b ). because a curved path is longer than a direct ( straight line ) path , a higher arc voltage is required to sustain the arc and the arc energy is diminished , thus suppressing ( quenching ) the arc 106 . fig4 is a graph of arc energy versus opening ( separation ) speed for two pairs of terminals , one pair of terminals , identified by curve a has magnetic field electrical arc suppression , while the other pair of terminals , identified by curve b , does not . curve a clearly indicates electrical arc suppression as compared to curve b , wherein the magnetic field has a value of 0 . 215t in the terminal proximity zone . the pair of terminals of curve a benefits from the magnetic field lengthening the arc and therefore increasing the necessary voltage to sustain the arc . this , in turn , shortens both arc duration and arc energy which reduces erosion of the terminals of curve a . fig5 and 6 depict a preferred example of a magnetic field electrical arc suppression assembly 110 integrated into an electrical connector 112 , collectively providing an arc suppressed connector 114 . fig5 shows merely by way of example two male terminals 116 , 118 located in the electrical connector 112 , which is female as defined by a shroud 120 . the shroud 120 , in turn , defines an interior space 122 . the terminal proximity zone z ( see fig6 ) is located generally at a mid - section of the interior space 122 . the terminals 116 , 118 are isolated by outer arc walls 124 and an inner arc wall 126 . the magnetic field arc suppression assembly 110 has a counterpart at each terminal 116 , 118 , each counterpart including a magnet 128 and a yoke 130 . the magnet 128 is of the permanent type and is located by the shroud 120 so as to laterally overlie the respective terminal across the terminal proximity zone z . the yoke 130 is composed of a high permeability ( ferromagnetic ) material , as for example iron , and includes a pole piece 132 which is positioned via the shroud diametrically opposite the magnet 128 . the facing pole 134 of the magnet 128 provides a magnetic field b across an air gap g to the pole piece 132 . the yoke 130 provides a u - shaped return flux path to the opposing pole 136 of the magnet so that a majority of reluctance the magnetic circuit is located at the terminal proximity zone . fig6 depicts a male mating connector 140 having female terminals 142 , 144 , shown mated with the arc suppressed connector 114 and its respective terminals 116 , 118 . in operation , should the mating connector 140 be separated from , or joined to , the arc suppressed connector 114 and the circuit connected with the terminals have a voltage applied across the terminals , an arc would tend to form across the terminal proximity zone , except that the magnetic field will suppress ( quench ) the arc because the path taken by the electrons between the terminals must be curved , as opposed to straight , as detailed and explained hereinabove . it will be understood that two permanent magnets could alternatively be utilized , wherein the second magnet is located where the pole piece is shown in fig5 ( that is , it replaces the pole piece ), and wherein the yoke would be u - shaped so as to provide a return flux path between the opposing poles of each of the magnets . further , the magnetic circuit can be designed to suit size , weight , cost and other criteria , in which , for example , a single magnet may provide a magnetic field for a number of terminal proximity zones . turning attention now to fig7 though 9 , an alternative example of a magnetic field electrical arc suppression assembly 210 integrated into an electrical connector 212 , collectively providing an arc suppressed connector 214 . fig7 shows merely by way of example two male terminals 216 , 218 located in the electrical connector 212 , which is female as defined by a shroud 220 . the shroud 220 , in turn , defines an interior space 222 . the terminal proximity zone ( see fig8 ) is located generally at a mid - section of the interior space 222 . the terminals 216 , 218 are isolated by outer arc walls 224 and an inner arc wall 226 . the magnetic field arc suppression assembly 210 has a counterpart at each terminal 216 , 218 , each counterpart including a magnet 228 and a yoke 230 . the magnet 228 is of the electromagnet type , which may advantageously include a ferromagnetic core , and is positioned via the shroud 220 so as to laterally overlie the respective terminal across the terminal proximity zone z . the yoke 230 is composed of a high permeability ( ferromagnetic ) material , as for example iron , and includes a pole piece 232 which is located in the shroud diametrically opposite the magnet 228 . the facing pole 234 of the magnet 228 provides a magnetic field b across an air gap g to the pole piece 232 . the yoke 230 provides a u - shaped return flux path to the opposing pole 236 of the magnet so that a majority of reluctance the magnetic circuit is located at the terminal proximity zone . current to energize the windings 238 of each of the magnets 228 is provided by a separate circuit 246 ( see the wiring diagram of fig9 ). fig8 depicts a male mating connector 240 having female terminals 242 , 244 , shown mated with the arc suppressed connector 214 and its respective terminals 216 , 218 . in operation , should the mating connector 240 be separated from , or joined to , the arc suppressed connector 214 and the circuit connected with the terminals have a voltage applied across the terminals , an arc would tend to form across the terminal proximity zone , except that the magnetic field will suppress ( quench ) the arc because the path taken by the electrons between the terminals must be curved , as opposed to straight , as detailed and explained hereinabove . the current to power the magnet 228 may alternatively be provided by the terminal circuit 248 , itself , as depicted by the wiring diagram of fig1 . it is believed in this regard , that when the terminals separate , the magnetic field collapse is momentarily postponed by electrical arcing . accordingly , the magnetic field will serve to suppress ( quench ) the arc before and during its collapse . on the other hand , it is believed that when the terminals approach contact , in order for an arc to be present , a current must be flowing in the windings , whereupon the magnetic field will serve to quench the arc . of course , in either case , any electromotive force due to inductance of the windings should be considered in designing the magnets 228 . it will be understood that two electromagnets could alternatively be utilized , wherein the second magnet is located where the pole piece is shown in fig7 ( that is , it replaces the pole piece ), and wherein the yoke would be u - shaped so as to provide a return flux path between the opposing poles of each of the magnets . further , the magnetic circuit can be designed to suit size , weight , cost and other criteria , in which , for example a single magnet may provide a magnetic field for a number of terminal proximity zones . to those skilled in the art to which this invention appertains , the above described preferred embodiment may be subject to change or modification . such change or modification can be carried out without departing from the scope of the invention , which is intended to be limited only by the scope of the appended claims .
