    This application claims priority for United States Provisional Patent Application Serial Number 61 / 347,216; filed on May 21, 2010; titled "Adapter for Bushing Latch" by Paul Michael Roscizewski and David Charles Hughes; and, as such, it is incorporated as a reference here for all purposes. TECHNICAL FIELD
    The present invention generally relates to medium voltage connectors for front-end electrical equipment, and, more particularly, to an adapter for interfacing a spike-type suppressor elbow connector with a disconnectable bushing connector without 600 amp nominal class load on medium voltage electrical equipment. BACKGROUND
    In a typical power distribution network, substations deliver electrical power to consumers via interconnect cables and electrical devices, for example, transformers, switches, circuit breakers, fuses, etc. The cables end in bushings that pass through the walls of a metal enclosure equipment, such as capacitors, transformers, distribution mechanisms, etc. Increasingly, this equipment is "front without current", meaning that the equipment is configured so that an operator cannot make contact with any electrical parts with current. Chainless front systems have proven to be safer than "chain forward" systems with comparable reliability and low failure rates. Various safety codes and operating procedures for underground power systems require a visible disconnect between each cable and electrical device for safely performing routine maintenance work, such as line-up checks, grounding, troubleshooting and testing high power. An approach to suit this requirement for a front-end electrical appliance with no current is to provide a "separable connector system" including a first connector set connected to the appliance and a second connector set connected to an electrical cable. The second connector set is selectively positionable with respect to the first connector set. An operator can attach and detach the connector assemblies to obtain an electrical connection or disconnection of the device and cable.
    Generally, one of the connector sets includes a female style connector and the other of the connector sets includes a corresponding male style connector. During a typical operation for creating an electrical connection, an operator slides a female-style connector over its corresponding male-style connector. In some cases, each of the connector assemblies may include substantially parallel female-style connectors in a row, and the other of the connector assemblies may include substantially parallel male-style connectors that correspond to and are aligned with the female-style connectors.
    In general, two basic types of separable connector systems have conventionally been provided, specifically, unloadable disconnect connector systems and loaded disconnect connector systems. Loadless disconnect connector systems require a connection or cable communication device while the equipment and cables are de-energized. That is, the disconnected, unloaded connectors are combined and separated only when there is no voltage present or a load current flowing through the connectors. A screw connection is made so that the cable connector is threaded onto the bushing with a coupling screw, for example, on a 600A T-body disconnectable unloadable elbow. The unloadable unplug connector systems for equipment high voltage are typically rated for 600 ampere currents.
    To avoid power interruptions required by unplugged disconnect connector systems, unplugged disconnect connector systems have been employed, which allow connection and disconnection to equipment when an operating voltage and a load current are present. This is done with a special arc interruption probe tip on the disconnectable unloaded elbow. Unloaded disconnect connector systems, however, are typically rated for much lower currents (typically around 200 amps) than unloaded disconnect connector systems. The loaded disconnectable elbow connector comprises an insulated portion that has a recessed internal tapered opening, a threaded ear and a loaded disconnectable probe with an arc follower tip portion. The disconnected probe with load is made from a conductive material that contacts corresponding claw contacts in a disconnectable bushing connector with combination load to complete a circuit, which includes the disconnectable elbow with load and the disconnectable connector with combination load . When combined together, one end of the male-type taper-shaped bushing connector is disposed substantially within the internal tapered opening in the disconnected elbow with load. In the recessed internal tapered opening, the loaded detachable elbow includes a locking ring that is molded into the body of the detachable elbow connector with load that keeps the elbow detachable with load mechanically coextensive with the detachable male connector with load of combination (for example, a pluggable plug with load). For connection and disconnection of disconnected connectors with load, a person can manipulate the suppressor elbow to and from the male connector (for example, a disconnectable plug with load) by using a live line tool or "hot pin" on a look of operation of the disconnectable elbow with load to push to or remove the disconnectable elbow with load from the disconnectable bushing with load. The different mechanical and electrical combination interfaces of the 600 A pluggable disconnectable and 200 amp pluggable connectors are not compatible with each other; however, both use similar isolated mechanical conical portions of the male bushing and the female elbow. Transformers used in wind farm applications are generally equipped with 600 A unloadable disconnect bushings. To obtain overvoltage protection for the system, elbows having built-in surge arresters or surge suppressors ("suppressor elbows") are attached to the transformer bushings. Traditionally, companies have only suppressors offered on detachable elbows with a load of 200 A, which, as stated above, cannot be coupled directly to the disconnectable bushings without a load of 600 A. To compensate for this, companies have coupled intermediate connector adapters, such as as an extender in combination with a pluggable disconnectable reduction bypass plug (LRTP), between standardized 600A unpluggable disconnect bushings and 200A suppressor load disconnectable elbows. This approach is not desirable, at least, because the extra parts require an increased installation cost and increase the spacing requirements without chain for this type of 600 A bushing configuration - LRTP adapter - 200 A suppressor elbow. SUMMARY
    Therefore, what is needed is a less expensive and more compact adapter to have a 600A unloadable plug-in interface with a push or pull suppressor elbow when used for applications normally not carrying current, for example, surge arresters and surge suppressors. This can be accomplished, according to the teachings of this exhibition, by the provision of an adapter for connecting a disconnected unloadable elbow specially designed to the 600 amp unloadable disconnect bushing, configured in a similar factor to a disconnected unloaded elbow 200 amps. This adapter comprises a separable assembly in two parts that has first and second ends. The first end is threaded to match a threaded opening in the unloadable disconnect bushing and the second end is threaded to match a threaded opening in an unloadable unloadable elbow ear. The two-part separable assembly is coupled together with the first part of the assembly that is threaded on the disconnectable bushing without load and has a groove that fits with pressure (engages) on a corresponding engagement ring on a molded insertion of the disconnectable elbow without load that surrounds the second part of the threaded assembly in the ear inside the disconnectable elbow without load. Other engagement mechanisms can be used to mechanically and electrically couple the first and second parts of the adapter assembly together, for example, burr and groove, engagement ring, etc. The adapter set can also be spring loaded for increased electrical contact pressure (lower connection resistance).
    According to a specific example of this exhibition, an adapter for coupling a disconnectable bushing without load together and a detachable suppressor elbow without a push / pull combination load comprises: a probe that has a threaded end and an end contact opposite the threaded end thereof; and a socket having a threaded end and a contact end opposite the threaded end thereof; where: the threaded end of the probe is threaded into a connector on an unloadable disconnectable suppressor elbow, the threaded end of the socket is threaded into a threaded opening on an unloadable disconnectable bushing, and when the unloadable unloadable suppressor elbow is positioned on the disconnectable bushing without load and forced on it, the probe and socket contact ends create an electrical and mechanical connection between them.
    According to another example specific to this exhibition, an adapter for coupling together an unloadable disconnectable bushing and an unloadable unloadable suppressor elbow includes: an unloadable disconnectable probe that has a threaded end and an end of contact opposite the threaded end thereof; and a socket having a threaded end, a contact end opposite the threaded end thereof and an engagement ring groove in an outer circumference of the socket and substantially coextensive with the contact end thereof; where: the threaded end of the unloadable unloadable probe is threaded into a connector on an unloadable unloadable suppressor elbow, the threaded end of the socket is threaded into a threaded opening on an unloadable unplugged bushing, when the unplugged suppressor elbow unloaded is positioned on the disconnected and unloaded bushing and forced on it, the contact ends of the probe and socket create an electrical connection between them, and in which the engagement ring groove fits into an engagement ring at one end of a conical opening of the unloadable disconnectable suppressor elbow, whereby the unloadable disconnect bushing and the unloadable disconnectable suppressor elbow are thus kept mechanically in contact.
    According to yet another specific example of this exhibition, a method of coupling together an unloadable disconnectable bushing and an unloadable unloadable suppressor elbow comprises the steps of: threading an unloadable disconnectable probe into a connector on an unloadable disconnectable suppressor elbow; threading an unloadable disconnectable socket into a threaded opening in an unloadable disconnect bushing; and push the unloadable disconnectable suppressor elbow over the unloadable disconnect bushing, in which the unloadable disconnect probe and the unloadable disconnect socket create an electrical and mechanical connection between them.

    Although the present exhibition is susceptible to several modifications and alternative forms, the specific examples of it have been shown in the drawings and are described here in detail. It should be understood, however, that the description here of specific example modalities is not intended to limit exposure to the particular forms exposed here, but, on the contrary, this exposure is to cover all modifications and equivalents, as defined by the claims in appendix. DETAILED DESCRIPTION
    Referring now to the drawings, details of specific exemplary embodiments of the present invention are illustrated schematically. Similar elements in the drawings will be represented by equal numbers, and similar elements will be represented by equal numbers with a different lowercase suffix.
    With reference to figure 1, an exploded view in schematic elevation of a cross section of a 600 A unloadable plug-in sleeve, a disconnectable unloadable suppressor elbow with a push / pull load and an adapter between them, according to an embodiment, is described specific example of this exhibition. A conventional unloadable plug-in male connector commonly known in the industry as a "600 A unloadable plug-in bushing" is represented by the number 128. Bushing 128 includes an opening 126 that has an internal 5 / 8-11 thread, which is configured for mechanical connection to a corresponding threaded screw of a combination connector (not shown), for example, a T-body elbow or T-head, whereby bushing 128 and the combination T-body connector (not shown) are mechanically and electrically linked on call. For the connection and disconnection of these types of disconnectable connectors without a load of 600 A, the set of threaded screw on the T-body elbow (not shown) is rotated until the threaded screw is unscrewed from the threaded opening on bushing 128. Then, the T-body elbow (not shown) can be removed from the 600 A 128 unloadable disconnect bushing that is normally mounted on a front-facing electrical equipment panel (not shown).
    An unloadable unloadable suppressor elbow is represented by the number 102. This unloadable unloadable suppressor elbow 102 comprises a molded EPDM insulation body 126 surrounding an electrical connector 110 that has a threaded hole at an end opposite a surge suppressor or attached lightning rod 106, an isolated pull eye 104 is attached to the outside of the body 136. The conical shape opening 112 of the unloadable disconnectable suppressor elbow 102 is adapted to fit over the conical shape bushing 128 The bushing coupling adapter, according to the teachings in this exhibition, allows a coupling of the voltage sensor 192 to the 600 A standardized unloadable bushing 128 without requiring a disconnectable reduced bypass plug (LRTP) (no shown). The surge suppressor or surge arrestor 106 is connected to the ground via a grounding wire 108. The bushing coupling adapter of figure 1 comprises a non-disconnectable short-load probe 116 and a combination socket 118. Probe 116 has a threaded end 122 which is threaded into connector 110, and socket 118 has a threaded end 124 which is threaded into opening 126 of bushing 128. It is contemplated and within the scope of this exposure that socket 118 may or may not be spring loaded, and probe 116 may be of a burr design to be better maintained in socket 118, or smooth to slide easily into socket 118.
    Probe 116 can be pre-assembled with connector 110 on the unloadable unloadable suppressor elbow 102 at the factory or in the field, and socket 118 installed in the field on an existing 600A bushing 128. Socket 118 can have a groove of engagement ring 120 on an outer circumference of the end opposite the threaded end 124, and be adapted to match an engagement ring 114 molded into a semiconductor insert 138 located within the disconnectable suppressor elbow without isolated load 102. The engagement ring 114 and engagement ring groove 120 mechanically engage and hold probe 116 and socket 118 firmly together.
    For connection of bushing 12 8 and unloadable unloadable suppressor elbow 102 together, an electrician pushes the unloadable unloadable suppressor elbow 102 to bushing 128 with a hot pin or live line (not shown) (through the operation or pull 104), so that groove 120 fits into engagement ring 114. An interference fit or "engagement force" between groove 120 and engagement ring 114 securely and mechanically combines the bushing 128 and the unloadable unloadable suppressor elbow 102 together, when the bushing 128 and the unloadable unloadable suppressor elbow 102 are electrically connected together. For disconnection of bushing 128 and disconnectable unloadable suppressor elbow 102, the electrician removes the disconnectable unloadable suppressor elbow 102 from bushing 128 with the hot pin or live line (not shown) (through the operating eye 104) strong enough to overcome the engagement force between groove 120 and engagement ring 114. A person of ordinary skill in the art and having the benefit of the present disclosure will recognize that many other alternative engagement mechanisms can be used and are contemplated here.
    With reference to figure 2, a schematic elevation view of a cross section of a 600 A bushing is described, a disconnectable suppressor elbow without pushing / pulling load and an adapter between them, shown in figure 1, according to with the specific example of this exhibition. The bushing 128 and the elbow 102 are coupled together as shown, and remain securely together with the mechanical cooperation of the groove 120 and the engagement ring 114.
    With reference to figure 3, an exploded view in schematic elevation of a cross section of a 600 A bushing is described, a disconnectable suppressor elbow with no push / pull load and an adapter between them, according to another example modality this exhibition. Bushing 128 and elbow 102 are the same as those described in figure 1 here above. The bushing coupling adapter of figure 3 comprises a short disconnectable probe 316 and a combination socket 318 that has a sliding electrical contact 317 and a loading spring 340 therein. Probe 316 has a threaded end 322 that is threaded into connector 110, and socket 318 has a threaded end 324 that is threaded into opening 126 of bushing 128. Loading spring 340 is used to guide the sliding electrical contact 317 toward to a contact end of probe 316 to reduce the electrical contact resistance between them.
    Probe 316 can be pre-assembled with connector 110 on the unloadable unloadable suppressor elbow 102 at the factory or in the field, and socket 318 installed in the field on an existing 600A bushing 128. Socket 318 can have a engagement ring 320 on an outer circumference of the end opposite the threaded end 324, and be adapted to match an engagement ring 114 molded into a semiconductor insert 138 located within the disconnectable suppressor elbow without isolated load 102. engagement ring 114 and thermistor 320 mechanically fit together and hold probe 316 and socket 318 together. Referring to figure 4, a schematic elevation view of a cross section of a 600 A bushing, a disconnectable suppressor elbow, is described no push / pull charge and an adapter between them, as shown in figure 3, according to the other specific example of this exhibition. Bushing 128 and elbow 102 are coupled together as shown and remain securely together with the mechanical cooperation of the groove 320 and the engagement ring 114. In addition, the loading spring 340 guides the sliding electrical contact 317 towards a contact end of probe 316 to reduce the electrical contact resistance between them.

Bushing 128 and elbow 102 are the same as those described in figure 1 here above. The bushing engagement adapter of figure 5 comprises a non-disconnectable short-load probe 516. Probe 516 has a threaded end 522 which is threaded into the opening 126 of bushing 128. Probe 516 is configured in a burr shape at one end 532 which mechanically cooperates with an internal engagement ring 530 within the opening of socket 518 to mechanically hold probe 516 and socket 518 together when elbow 102 is forced on bushing 128.
    Probe 516 can be pre-assembled with connector 110 on the unloadable unloadable suppressor elbow 102 at the factory or in the field, and socket 518 installed in the field on an existing 600A bushing 128. Socket 518 has a snap ring 530 on an inner circumference of the end opposite the threaded end 524, and is adapted to match a burred portion of the probe 516. The engagement ring 530 and the burred portion of the probe 516 fit mechanically and securely hold the probe together 516 and socket 518. An orientation collar 528 can be additionally used to increase the compression force between the engagement ring 530 and the burr portion of the probe 516.
