    KNOWLEDGE Field
    [0001] The disclosed concept generally refers to circuit breakers and more particularly to circuit breaker sets such as, for example, circuit breaker panels for a number of circuit breakers. Knowledge Information
    [0002] Circuit breakers are used, for example, in aircraft electrical systems where they not only provide overcurrent protection, but also serve as switches to turn equipment on and off. Subminiature or aircraft circuit breakers, for example, typically are relatively small to accommodate the relatively high density design of aircraft circuit breaker panels, which make up circuit breakers for multiple circuits accessible to a user. Aircraft electrical systems can consist, for example, of hundreds of circuit breakers, each of which is used for a circuit protection function as well as a circuit disconnect function via a push-pull handle.
    [0003] The push-pull handle of the circuit breaker is moved from the inside to the outside in order to open the corresponding load circuit. This action can be either manual or even automatic in the event of a fault or overload condition. If the push-pull handle is moved from the outside to the inside, then the load circuit is energized again. If the load circuit was automatically de-energized, then the outside-in operation of the push-pull handle corresponds to a reset action of the circuit breaker.
    [0004] Such circuit breakers typically include a threaded bezel. A suitable fastener, such as a nut and washer, mounts the circuit breaker in a corresponding opening of an aircraft circuit breaker mounting panel. The push-pull handle passes through the bezel to the user side of the mounting panel. The circuit breaker also typically includes load and line screw terminals disposed on the opposite maintenance side of the mounting panel.
    [0005] US Patent No. 8,094,436 discloses a circuit breaker assembly, such as a plug switch panel, including a housing, a busbar structure coupled to the housing, and a number of first plug members coupled to the housing. busbar structure. A number of circuit breakers include a first surface and a second plug member disposed opposite the first surface. The second plug member of each of the number of breakers is matched with a corresponding one of the number of first plug members. A plate member is detachably coupled to the housing. The plate member includes a first surface and an opposite second surface. The first surface of the number of breakers engages the opposite second surface of the plate member so as to match each of the number of breakers with the corresponding one of the number of first plug members.
    [0006] If the plug breaker panel is desired to be mounted in an overload configuration with the push-pull operating handle of breakers that are generally arranged downwards, then a retention problem for the plug breakers may result whether the plate member, such as a face plate or cover member, is removed, for example, for maintenance or problem diagnosis or correction.
    [0007] There is room for improvement in breaker sets. SUMMARY
    [0008] These and other needs are satisfied by the modalities of the disclosed concept in which a number of insulating retainers is arranged around a corresponding number of a number of first plug members, so as to isolate the corresponding number of the number of first members of plug, and to retain a number of second plug members from a number of circuit breakers which electrically engage the corresponding number of the number of first plug members.
    [0009] According to an aspect of the disclosed concept, a circuit breaker assembly comprises: a housing; a busbar structure within the housing; a number of first plug members coupled to the busbar structure; a number of insulating retainers coupled to the electrical bus structure, a corresponding number of insulating retainers which is operatively associated with a corresponding number of the number of first plug members; and a number of circuit breakers, each of the number of circuit breakers comprising a manual operator and a number of second plug members disposed opposite the manual operator, the number of second plug members electrically engaging a number of the number of first plug members plug, wherein the corresponding one of the number of insulating retainers is arranged around the corresponding number of the number of first plug members, so as to isolate the corresponding number of the number of first plug members, and to retain the number of second members which electrically engage the corresponding number of the number of first plug members.
    [00010] The corresponding one of the number of insulating retainers can be structured to protect the corresponding number of the number of first plug members when they do not electrically engage the number of second plug members.
    [00011] Each of the number of first plug members can be a number of male terminals; the number of second plug members can be a number of female sockets; each of the number of insulating retainers may comprise, for one of the number of male terminals and one of the number of female sockets, an insulator comprising a base and an elongated portion extending from the base, the base having a first opening therein. the elongated portion having a second opening therein and a conduit extending therethrough from the first opening to the second opening; and the one of a number of male terminals may extend through the first opening and only partially through the conduit.
    [00012] The conduit can have a generally cylindrical shape and comprise a plurality of internal grooves; and the one of a number of female sockets may have a cylindrical shape within the generally cylindrical shape of the conduit and be engaged by the internal grooves therein.
    [00013] The number of insulating retainers can be structured to retain the number of circuit breakers with the manual operator which usually faces down.
    [00014] As another aspect of the disclosed concept, a circuit breaker assembly comprises: a housing; a busbar structure within the housing; a number of first plug members coupled to the busbar structure; a number of insulating retainers coupled to the electrical bus structure, a corresponding number of insulating retainers which is operatively associated with a corresponding number of the number of first plug members; a number of circuit breakers, each of the number of circuit breakers comprising a manual operator disposed from a first surface and a number of second plug members disposed from a second surface opposite the first surface, the number of second plug members that electrically engage a number of the number of first plug members; and a cover member removably coupled with the housing, the cover member comprising a third surface and a number of openings disposed through the third surface; wherein the corresponding one of the number of insulating retainers is arranged around the corresponding number of the number of first plug members, so as to isolate the corresponding number from the number of first plug members, and to retain the number of second plug members electrically engaging the corresponding number of the number of first plug members, wherein the first surface of the number of circuit breakers engages the third surface of the cover member, and wherein the manual operator passes through a corresponding number of openings.

    [00025] As used here, the term “number” must mean one or an integer greater than one (ie, a plurality).
    [00026] As used here, the statement that two or more parts are "connected" or "coupled" must mean that the parts are joined either directly or joined through one or more intermediate parts. Additionally, as used here, the statement that two or more parts are “attached” must mean that the parts are directly joined.
    [00027] As used herein, the term "fastener" refers to any fastening or connection mechanism that expressly includes, but is not limited to, screws, nails, nuts (for example, without limitation, fastening nuts) and combinations of the same.
    [00028] The disclosed concept is described in association with aircraft or subminiature circuit breakers, although the disclosed concept can be applied to a wide range of different circuit breakers for a wide range of different applications. Such circuit breakers can be employed, for example, and without limitation, in aircraft alternating current (AC) systems having a typical frequency of around 400 Hz, but can also be used in direct current (DC) systems. It will also be evident that the disclosed concept is applicable to other types of circuit breaker panels including those used in AC systems operating at other frequencies; for larger circuit breakers, such as miniature commercial or residential circuit breakers; and for a wide range of circuit breaker applications, such as, for example, residential, commercial, industrial, aerospace, and automotive. As additional non-limiting examples, both AC operation (eg without limitation, 120, 220, 480-600 VAC) in a large 'frequency range' (eg without limitation, 50, 60, 120, 400 Hz, and higher or lower frequencies) and DC operation (eg, without limitation, 42 VDC) is possible.
    [00029] Referring to Figure 1, a circuit breaker assembly such as the example circuit breaker panel 2 is shown. The circuit breaker panel 2 includes a housing 4 (partially shown in Figure 1), a busbar structure, such as the example multiple layers (for example, without limitation, four conductive layers) of the bottom plane 6 within the housing 4 , and a number of first plug members, such as example pins 8 (six example pins 8 are shown, although any number may be employed) coupled to the background 6. Breaker panel 2 additionally includes a number of insulating retainers 10 (three example retainers 10 are shown for the six example pins 8, although any suitable number may be employed) are coupled to the background 6. A corresponding number of insulating retainers 10, such as 10A, is operatively associated with a corresponding number of pin number 8, such as 8A and 8B. Circuit breaker panel 2 also includes a number of circuit breakers 12 (an example circuit breaker 12 is shown, although any suitable number may be employed).
    [00030] Each of the number of circuit breakers 12 includes a manual operator 14 and a number of second plug members, such as example sockets 16 (two example sockets 16A and 16B are shown, although any suitable number may be employed ) disposed opposite the manual operator 14. The number of second sockets 16 electrically engages a number of pin number 8, as shown with pins 8A and 8B. The corresponding 10A of the number of insulating retainers 10 is arranged around the corresponding number of the number of pins 8A and 8B, so as to isolate the corresponding number of the number of pins 8A and 8B, and to retain the number of sockets 16A and 16B that electrically engage the corresponding number of pin numbers 8A and 8B, respectively.
    [00031] Example plug breaker 12 includes the two built-in example plug sockets 16A and 16B, which are received by respective portions 10AA and 10AB of insulating retainers 10A. Pins 8A and 8B electrically engage sockets 16A and 16B within portions 10AA and 10AB, respectively. This serves to retain sockets 16A and 16B and thus the plug breaker 12 for overload applications and prevents breaker 12 from falling out (eg if a cover or face plate (not shown, but see cover or plate of face 48 of Figure 7) is removed). The insulating retainers 10 also provide electrical insulation between the conductors (eg pins 8A, 8B, 8C, 8D, 8E and 8F) for severe applications (eg through the provision of a moisture barrier), protect the pins ( eg pins 8C, 8D, 8E and 8F) in unused positions, and protect the user from electrical conductors (eg pins 8C, 8D, 8E and 8F) in unused positions.
    [00032] Figures 2-4 show a 10A of the insulating retainers 10 of Figure 1 including the two example portions 10AA and 10AB. This provides a single insulating retainer for the two example pins 8A, 8B for the example 12 single pole circuit breaker which has an 18 line terminal and a 20 load terminal. Example 1
    [00033] As shown with insulating retainers 10B, 10C of Figure 1, insulating retainers 10 are structured to protect corresponding pins 8C, 8D, 8E and 8F when they do not electrically engage sockets such as 16A and 16B, of a plug breaker, such as 12. As shown, pins 8C, 8D, 8E, and 8F are recessed into portions 10BA, 10BB, 10CA, 10CB, respectively. Example 2
    [00034] Each of the number of first plug members is a plurality of 8A-8B, 8C-8D, 8E-8F male terminals. The number of second plug members is a plurality of female sockets 16A-16B. Each of the number of insulating retainers 10A, 10B, 10C is operatively associated with a plurality of the plurality of male terminals, such as pins 8A and 8B, and a plurality of the plurality of female sockets, such as sockets 16A-16B , as shown with circuit breaker 12 in Figure 1. Example 3
    [00035] As best shown with the insulating retainer 10A of Figures 2-4, the insulating retainers 10 (Figure 1) include, for one of the two 8 male terminals and one of the two female sockets 16, an insulator as shown by the 10AA portion or 10AB, having a base 22 and an elongated portion 24 extending from the base 22. The base 22 has a first opening 26 therein. The elongated portion 24 has a second opening 28 therein and a conduit 30 (shown in the hidden line drawing in Figure 3) extending therethrough from the first opening 26 to the second opening 28. A pin such as 8A or 8B, extends through the first opening 26, into and partially through the conduit 30. A female socket, such as 16A or 16B, extends through the second opening 28 and partially through the conduit 30. The pin, such as 8A or 8B , electrically engages the female socket, such as 16A or 16B, into conduit 30. Example 4
    [00036] As best shown in Figures 1 and 3, the conduit 30 has a generally cylindrical shape and includes a plurality of internal grooves 32. The female socket, such as 16A or 16B, has a cylindrical shape within the generally cylindrical shape of conduit 30 and is engaged by internal grooves 32 therein. The internal grooves 32 within the insulating retainer portions 10AA, 10AB are for the retention and relief of air, as there is a need for a space for air to pass when inserting the circuit breaker sockets 16. Example 5
    [00037] The insulating retainers 10 are preferably made from liquid silicone rubber (LSR). LSR is a high purity platinum cure silicone. It is typically supplied in two parts with one part containing a platinum catalyst. These two parts are mixed together with any desired color and/or desired ingredients, and are extruded into the disclosed insulating retainer 10. Alternatively, the insulating retainers 10 can be made from a thermoplastic elastomer (TPE) or a rubber molding transference (thermal set). Example 6
    [00038] Insulating retainers 10, as shown at 10A, are structured to retain circuit breakers 12, as shown at 12A, with the manual operator 14 generally facing downwards (eg upwards with respect to Figure 1). Example 7
    [00039] As shown in Figure 1, each of the insulating retainers 10 includes the base 22 and is coupled to the multi-layer background 6 by a retaining layer 34 that engages the bases 22. The retaining layer 34 is coupled to manner suitable for the background 6. The retaining layer 34 is made of a thermally conductive thermoplastic or other suitable type of thermoplastic. The retaining layer 34 may be secured to the background 6 using a suitable adhesive (for example, without limitation, a Bond-Ply® 660 adhesive layer marketed by The Bergquist Company of Chanhassen, Minnesota, or by a suitable fastener (by example, without limitation, mechanical hardware; rivet) (not shown)). Example 8
    [00040] Figure 1 shows an insulating retainer 10A having two insulating portions 10AA,10AB for a single pole circuit breaker 12 having two sockets 16A,16B. If a three-pole circuit breaker (not shown) is employed, then three of the example 10 insulating retainers are employed. Example 9
    [00041] Figures 5 and 6 show another circuit breaker assembly, such as the example circuit breaker panel 36. The circuit breaker panel 36 can be the same as or similar to circuit breaker panel 2 in Figure 1 except the retaining layer of example 34 is not employed. Instead, insulating retainers 10 are coupled to a busbar structure, such as the multi-layer example background 38, by a suitable adhesive to bond retainers 10 thereto. Example 10
    [00042] Although Figures 1, 5 and 6 show circuit breaker panels 2, 36 where insulating retainers 10 have two insulating portions, such as 10AA, 10AB, for a single pole circuit breaker 12, the disclosed concept can be applied to other insulating retainers in which one of the rows 40 or columns 42 of Figure 6 is formed of a single insulating retainer (not shown) having relatively many insulating portions for multiple breakers (not shown); the entire background 38 employs a single insulating retainer (not shown) having relatively many very insulating portions for all breakers (not shown); a single insulating retainer (not shown) employs multiple portions of insulation for all poles of a multi-pole circuit breaker (not shown); or a single insulating retainer (not shown) employs multiple insulating portions for multiple breakers (not shown). Example 11
    [00043] Figure 7 shows another circuit breaker assembly, such as example breaker panel 44. Breaker panel 44 may be the same as or similar to breaker panel 2 in Figure 1 except the example retaining layer 34 is not employed, and may be the same as or similar to breaker panel 36 of Figures 5 and 6 except that a housing 46 including a cover member, such as the face plate or example cover 48, is shown. Circuit breaker panel 44 includes housing 46, a busbar structure, such as a multilayer backplane 50, a number of first plug members 52 coupled to the backplane 50, a plurality of coupled insulating retainers 10 to the background 50, and a plurality of the plug breakers 12. Each of the breakers 12 includes the manual operator 14 disposed from a first surface 54 and a number of second plug members, such as the two example sockets 56 , disposed from a second surface 58 opposite the first surface 54. The example sockets 56 electrically engage a number of the number of first plug members 52.
    [00044] The face plate or cover 48 is removably coupled to the housing 46 by the fasteners 60. The face plate or cover 48 has a surface 62 and a plurality of openings 64 disposed therethrough. The first surface 54 of the circuit breakers 12 engages the surface 62 of the face plate or the cover 48. Each of the manual operators 14 passes through a corresponding one of the openings 64. Example 12
    [00045] Insulating retainers 10 are structured to retain circuit breakers 12 with manual operators 14 which generally face down (for example, up with respect to Figure 7) when the face plate or cover 48 is removed from the housing 46. Example 13
    [00046] The face plate or cover 48 includes fasteners 60 that detachably engage housing 46. Example 14
    [00047] The number of second plug members, such as the two example sockets 56, include a first socket 56A for a 66 line terminal and a second socket 56B for a 68 load terminal. Example 15
    [00048] Manual operator 14 is a push-pull operating handle. Example 16
    [00049] Figure 8 shows another breaker assembly, such as the example breaker panel 70 including an installed breaker 12. Breaker panel 70 may be the same as or similar to breaker panel 2 in Figure 1 except that the example retaining layer 34 is not employed, may be the same as or similar to breaker panel 36 of Figures 5 and 6, or may be the same as or similar to breaker panel 44 of Figure 7 except housing 46 and the face plate or cover 48 is not shown.
    [00050] Disclosed insulating retainers 10 provide electrical insulation between conductors, such as pins 8. Electrical insulation is improved by increasing the distance of a potential arc path (for example, which is taken longer than that of a flat surface), protecting against foreign objects that can cause electrical shorts from the line to the load, and protecting unused pins 8 from other conductors.
    [00051] The disclosed insulation retainer 10 protects the background pins 8 from damage and the user from energized electrical conductors in unused positions. Background pins 8 are below the retainer surface when the corresponding breaker 12 is not populated. If a user installs a circuit breaker with the power on, then insulated retainer 10 provides added electrical protection from accidental shock.
    [00052] The disclosed concept overcomes known limitations of known plug breaker panels for applications such as, for example and without limitation: (1) various vibration applications by providing additional damping; (2) severe corrosion, moisture, elevation, wet areas and unpressurized use through the provision of a moisture barrier; (3) overload (suspended) applications that require the retention of circuit breakers when removing a cover or faceplate; and (4) those applications that require relatively higher dielectric support voltages between conductors (eg, 270 VDC).
    [00053] The disclosed silicone rubber retainer 10 provides the following features: (1) retaining circuit breakers without a face plate or circuit breaker panel cover being installed; (2) protection of unused pins from damage; (3) protection of object debris driving pins (FOD) between pins; and (4) added protection for the user from accidental shock.
    [00054] Disclosed insulating retainers 10 provide vibration dampening. By checking the compression of breaker sockets 16 as installed on breaker panels 2, 36, 44, 70 this prevents relative movement which can cause wear of the contacts which can cause overheating and eventually an open circuit.
    [00055] The disclosed insulating retainers 10 also provide a relatively hermetic fit around the built-in sockets of the circuit breaker 16 and the sealing of the electrical contact interface. This prevents moisture pooling, salt build-up and freezing. This also limits corrosion on mating pins 8 and embedded sockets 16.
    [00056] The disclosed insulating retainers 10 further protect against FOD. Conventional breaker panels in pressurized areas and non-pressurized areas are susceptible to debris accumulation (eg, without limitation, sand, dust, salt and loose hardware such as cable parts, nuts or washers). Securing the load and line terminals 18, 20 of the circuit breakers 12 will increase the reliability and safety of the application.
    [00057] The 10 disclosed insulating retainers also allow overload breaker assemblies. Retainers 10 hold circuit breakers 12 in place when maintenance is being conducted, for example to add or replace a circuit breaker with the face plate or cover 48 removed.
    [00058] While specific embodiments of the disclosed concept have been described in detail, it will be appreciated by those skilled in the art that various modifications and alternatives to those details can be developed in light of the general teachings of the disclosure. Appropriately, the particular arrangements disclosed should be illustrative only and not limiting as to the scope of the disclosed concept which should be given the full breadth of the appended claims and any and all equivalents thereto.
