FURTHER DESCRIPTION OF THE INVENTION

(11) FIG. 1 and FIG. 2 depict a connecting-conductor 10 that may be used within the housings of a plug and socket to place a resistor between two EE Conductors. In FIG. 1 and FIG. 2 there is a shown a first conductor-element 100 in the shape of a pin, a second conductor-element 300 in the shape of a socket, and these conductor-elements 100, 300 are joined together by a resistor-element 200. The overall length L and diameter D of the connecting-conductor 10 may be selected to be the same or very similar to the length and diameter of the existing pin or socket that is brought together in a conductive relationship when the plug housing is mated with the socket housing.

(12) The resistor-element 200 depicted in FIG. 1 as having an electrical-insulating substrate 210 and a resistive material 230 that is annularly disposed on at least part of the electrical-insulating substrate 210. A first end 110 of the first conductor-element 100 is mechanically-connected to the resistor-element 200, and electrically-conductively connected to the resistive material 230 via a first conductive material 250A that is annularly disposed on at least part of the electrical-insulting substrate 210. In a similar manner, a first end 310 of the second conductor-element 300 is mechanically-connected to the resistor-element 200, and electrically-conductively connected to the resistive material 230 via a second conductive material 250B that is annularly disposed on at least part of the electrical-insulting substrate 210. In this manner, the first conductor-element 100 does not touch the second conductor-element 300, and an electrical pathway is created via the resistive material 230 from one of the conductor-elements 100, 300 to the other of the conductor-elements 300, 100. And, the second ends 120, 320 of the conductor-elements 100, 300 are depicted as being available for joining to other components. For example, the second end 320 of conductor-element 300 may be joined to an EE Conductor, and the second end 120 of the conductor-element 100 may be mated with a socket conductor that resides within one of the plug or socket housings. For clarity, if the connecting-conductor 10 shown in FIGS. 1 and 2 is associated with a plug housing, then the corresponding socket housing would contain a socket that mates with the second end 120 of conductor-element 100 when the plug housing and the socket housing are mated. Alternatively, if the connecting-conductor 10 shown in FIGS. 1 and 2 is associated instead with a socket housing, then the corresponding plug housing would contain a socket that mates with the second end 120 of conductor-element 100 when the plug housing and the socket housing are mated.

(13) The conductive material 250A, 250B is shown in FIGS. 1 and 2 annularly disposed on at least part of the electrical-insulating substrate 210. Each of the conductive materials 250A, 250B is also shown in FIGS. 1 and 2 electrically-conductively and mechanically-connected to one of the conductor-elements 100, 300 as well as to the resistive material 230. In this manner, an electrical pathway is created via the resistive material 230 from one of the conductor-elements 100, 300 to the other of the conductor-elements 300, 100.

(14) It should be noted that the word annularly is used herein to identify not only rings of material that are substantially circular, but other shapes as well. For example, if the electrical-insulating substrate 210 is triangular, or square, or oval shaped, then the annularly disposed conductive material 250A, 250B as well as the resistive material 230 may have a corresponding triangular, or square, or oval shape too. Thus, the word annularly is used herein in a manner that is broader than its tradition definition to refer to shapes other than circular rings.

(15) The mechanical and electrical connection between the conductor-elements 100, 300 and the conductive material 250A, 250B of the resistor-element 200 may be achieved by placing beads 400A, 400B (such as that shown in FIG. 1) of conductive solder or conductive epoxy where the conductor-elements 100, 300 are close to their corresponding conductive-material 250A, 250B, and allowing that bead to harden. However, the mechanical connection between the conductor-elements 100, 300 and the resistor-element 200 may be achieved or augmented in other ways. For example, a non-conductive epoxy may be used to join the conductor-elements 100, 300 directly to the electrical-insulting substrate by applying the epoxy to those surfaces of the conductor-elements 100, 300 and/or to the electrical-insulating substrate 210 that are placed in close proximity to each other during formation of the connecting-conductor 10.

(16) The mechanical connection between the conductor-elements 100, 300 and the electrical-insulating substrate 200 may be strengthened by providing one or more legs that extend into a conductor-element. For example, FIG. 1 shows such a leg 220 (see also FIGS. 3A and 3B) extending into the first end 310 of the second conductor-element 300. The second conductor-element 300 has an internal surface 330 into which the leg 220 extends and resides.

(17) The mechanical connection between the conductor-elements 100, 300 and the electrical-insulating substrate 200 may be strengthened by providing one or more receiving holes in the electrical-insulating substrate 200, such as the partial receiving hole 270 (see FIG. 3B) that is shown in FIG. 1 accepting the first end 110 of the first conductor-element 100. Other arrangements are possible. For example, FIGS. 4A and 4B depict an embodiment of the invention in which the electrical-insulating substrate 210 has two receiving holes (each a partial hole), one receiving hole for receiving the first end 110 of the first conductor-element 110, and another receiving hole for receiving the first end 310 of the second conductor-element 310.

(18) FIG. 4C depicts another embodiment of the invention in which the electrical-insulating substrate 210 has a receiving hole 270 that extends through the electrical-insulating substrate 210. Annularly applied to the surface defining that receiving hole 270 is the resistive material 230. When assembled, the shoulders 140, 340 of the conductor-elements 100, 300 touch and/or are electrically connected to the conductive material 250A, 250B.

(19) FIGS. 5A and 5B depict another embodiment of the invention in which legs 220A, 220B of the electrical-insulating substrate 210 extend into the conductor-elements 100, 300. Note that the conductor-elements 100, 300 shown in FIG. 5B are different types. The conductor-element 300 is a tube from end 310 to end 320, whereas the conductor-element 100 is not a full tube and instead has a portion that is tubular in the vicinity of end 110. This need not be the case, for example, the connecting-conductor 100 shown in FIG. 5B may be replaced with a full-tube type so that the types of connecting-conductors are the same type. For emphasis of this idea, the conductor-elements 100, 300 may be the same type (e.g. see FIGS. 4B and 4C), or different types (e.g. FIGS. 1 and 5B). Throughout the figures, there are shown various types of conductor-elements, and it should be noted that such types are not necessarily limited to use in the particular embodiments depicted. For example, the partial-tube type shown in FIG. 5B for the conductor-element 100 could be used in the embodiment of FIG. 1 as the conductor 300.

(20) The resistor-element 200 may be formed by applying the conductive material 250A, 250B to the electrical-insulating substrate 210, for example by spraying or dipping procedures, and the resistive material may be applied to the electrical-insulating substrate 210 by similar procedures. The effective resistance of the resistor-element 200 may be selected by varying the amount of conductive material 250A, 250B and resistive material 230 used, while maintaining a desired thicknesses of those materials.

(21) It is worth noting that the particular arrangement shown in the figures are not the only viable arrangements. For example, the locations of the conductive materials and the resistive material may be reversed. That is to say for example that the area identified in FIG. 1 by 230 may be a conductive material, and the areas identified in FIG. 1 by 250A and 250B may be the resistive material.

(22) The electrical-insulating substrate 210 may be a ceramic material, a plastic material, a polymer material having the ability to electrically insulate one electrically conductive substance from another. For example, the electrical-insulating substrate 210 may be porcelain, alumina, steatite, titanate, and/or glass. The resistive material 230 may be carbon, a composition of carbon, or other materials that resist but do not prevent the transmission of electricity. The conductor-elements 100, 300 may be copper, copper alloy (such as bronze or brass), steel, aluminum, aluminum alloy, as well as other conductive substances. The conductive material 250A, 250B may be copper, copper alloy (such as bronze or brass), tin, tin alloy, aluminum, aluminum alloy, gold, nickel, and/or silver, as well as other conductive substances.

(23) Although the present invention has been described with respect to one or more particular embodiments, it will be understood that other embodiments of the present invention may be made without departing from the spirit and scope of the present invention. Hence, the present invention is deemed limited only by the appended claims and the reasonable interpretation thereof.
