Description

ASSEMBLY OF AUTOMATIC CIRCUIT SWITCHES WITH INHIBITOR ASSEMBLY BACKGROUND OF THE INVENTION The invention is generally directed to circuit breakers, and in particular, to an improved circuit breaker assembly designed to prevent two circuit breakers cooperating from simultaneously being in the ON position. The present invention also addresses techniques for modifying a circuit breaker load center to accommodate a variety of circuit breaker configurations. Finally, the invention is directed to an improved box, and in particular to a rainproof housing construction and a method for manufacturing it. Circuit breaker assemblies comprising, for example, two main automatic feedback switches (one line from a standard service and one line from a generator) are well known in the art. At least one attempt has been made to construct an assembly so that it is impossible for the circuit breakers to be in the ON position at the same time. This inhibition assembly is typically constructed to allow both circuit breakers to be in the OFF position, while ensuring that only one of the two circuit breakers is always in the OFF position when the other of the two circuit breakers be in the ON position. However, the known circuit breaker assembly is less than desirable because of its lack of adaptation to an assembly in which the two circuit breakers are in front alignment. That is, the known assembly uses an inhibition assembly that can only be applied when the circuit breakers are in a side-by-side arrangement in which the switches of the same move in the SAME direction to be both ON or OFF. both OFF. The circuit breaker assembly of the art is also deficient in its inability to provide a load center assembly that can easily accommodate a plurality of circuit breaker arrangements with only minor modifications thereto. This is, for example, to modify an assembly of eight circuit breakers of the state of the art so that only accepts six circuit breakers, it is now necessary to machine cut a portion of the terminal assembly of holes to avoid inadvertent coupling of additional automatic switches. Due to the different needs of different users, it is desirable to incorporate a reject array during the molding process from a load center assembly to a customer-adapted design to accept variant circuit breaker arrangements and eliminate difficult machining processes for carry out this result. To date there is no technique to provide this feature in the field. Also deficient in the technique of circuit breakers is the ability to build a rainproof housing that overcomes the problem of water runoff. Currently, the known accommodations that are typically of a three-piece construction, will allow the water to get into the banks. This is due to the construction of the same accommodation. In accordance with the foregoing, it is desirable to provide automatic circuit breaker assemblies and circuit breaker housings that overcome the aforementioned deficiencies. In particular, it is desirable to provide an inhibition assembly which can be easily incorporated into an automatic circuit breaker assembly where the circuit breakers are in front alignment and which inhibits the circuit breakers from simultaneously being ON. It is also desirable to mold a saddle-shaped assembly that meets the needs of an end user in a more economical and efficient manner. By last, it is desirable to provide a rainproof housing construction that eliminates water filtration. The invention described herein accomplishes the aforementioned objectives as well as those mentioned below.

COMPENDIUM OF THE INVENTION In general, in accordance with the present invention, an automatic circuit breaker assembly is provided. In the preferred embodiment, the assembly (10) comprises a first circuit breaker (12) having a pivoting switch assembly (24, 26, 30) movable between a first position and a second position, the movement of the toggle switch assembly from the first position to the second position is in a first direction, a second circuit breaker (14) having a swiveling switch assembly (25, 27, 30) movable between a first position and a second position, the movement of the assembly of the rocker switch from the first position to the second position is in the same direction as the first direction and the inhibitor connectors (40, 42) to prevent the rocker switch assembly of the first circuit breaker from being in the second position when the toggle switch assembly of the second circuit breaker is in the first position. In another aspect of the present invention, a process for molding a saddle-shaped base (105) is provided. In the preferred embodiment, the process includes the steps of providing a mold to form a saddle-shaped base (105) capable of releasably securing n automatic circuit breakers therein, determining an undesirable number of circuit breakers of the circuit breaker (105). circuit for which it is undesirable to mount on the saddle-shaped base, where the undesirable number is less than n, and integrally mold a selected number of rejection blocks (167, 168) to the base in the form of a saddle assemble during molding the base in the form of a saddle to prevent the undesirable number of circuit breakers from being secured to the base in the form of a saddle. Finally, in another aspect of the present invention, an improved rainproof housing is provided. In the preferred embodiment, the housing comprises a first (201), a second (202), third (203) and fourth (206) side walls, and a lower (207) and upper side. The first, second and third side walls and the bottom side are integrally formed and the first and second walls include overlapping sides (205, 204). The housing is formed by defining a single slot configuration (230, 231) which defines the first and second side walls and the two overlapping sides therethrough, bending the first and second walls along previously determined fold lines (A, E ), by folding the first and second overlapping sides along other previously determined bending lines (B, D) and folding the third side wall along a previously determined third bending line (C), securing the walls together side and overlapping sides as well as the fourth side wall and a top portion to the housing and providing that the overlapping sides, which will include the respective overlapping areas (Z), overlap any voids formed between the side walls.

DETAILED DESCRIPTION OF THE PREFERRED MODALITIES Reference is generally made to Figure 1 which illustrates an automatic circuit breaker assembly, indicated generally as 10, constructed in accordance with the present invention. In particular, there is shown a two pole circuit breaker, generally indicated as 12, and a second two pole circuit breaker, generally indicated as 14. The circuit breakers 12 and 14 are in front alignment with each other. It should be noted that the exemplary embodiment represents two circuit breakers of two poles in frontal alignment, but it should be understood that the present invention is equally applicable to two single-pole circuit breakers accommodated in facing alignment, or to a multitude of circuit breakers where there are at least two circuit breakers in frontal alignment. The circuit breakers 12 and 14 are mounted in front alignment in a load center of multiple circuit breakers 16, the details of which do not need to be discussed as they would be understood by a technician with ordinary experience in the field. A plurality of perforated terminals 19 are provided to receive the first terminal ends of the respective circuit breakers. The circuit breaker 12, being a two-pole circuit breaker, includes a toggle switch assembly which includes a first rocker switch 24 and a second rocker switch 26 for at least essentially simultaneously setting the circuit breaker 12 in the ON position or in the OFF position. Similarly, the two-pole circuit breaker 14 includes a rocker switch assembly that includes a first rocker switch 25 and a second rocker switch 27 for at least essentially simultaneously setting the circuit breaker 14 to the ON position. OFF position. Hereinafter, reference will sometimes be made to the construction of the present invention as applied with respect to the circuit breaker 12, being similarly applicable to the circuit breaker 14. Each switch assembly may also include a busbar of switch, generally indicated as 30, which comprises a front plate 32, a rear plate 34 and an integrally formed connecting member 36. The bar 30 couples each of the respective pairs of rocker switches. In the preferred embodiment, each of the switches 24-27 may also be formed in some hollow manner (see Figure 2) so as to receive outwardly extending arms 37 extending from the member 36 of the bar 30. That is, the extension arms 37 (see Figure 2) of the bar 30 can be inserted into the internal region of the switches 24-27 to add rigidity to the rocker switch assembly of each circuit breaker and facilitate tilting at least substantially simultaneous of each pole of the respective two-pole circuit breaker 12, 14. In assembly 10 it also includes a first inhibitor connector 40 and a second inhibitor connector 42, the constructions thereof being identical. Therefore reference will be made to the connector 40, the details of which are identical for the connector 42. The preferred embodiment of the inhibitor connectors 40, 42 is illustrated in Figures 3 and 4. The connector 40 is preferably of a unitary plastic construction. . The connector 40 includes a head 43 and a tail 44. For added rigidity, the head 43 is preferably square or rectangular in shape and may include an internal wall 46 (shown in dotted lines in Figure 3). The tail 44 includes at least one lower surface 48, an upper surface 50 and an integrally formed fin 55. The tail 44 may also include an inner wall 56 which adds stability thereto. It will be seen from Figure 3 that the tail 44 generally has a trapezoidal cross-section so that it cooperates more easily with the track 57, 58 formed between each of the circuit breakers comprising two-pole circuit breakers 12. , 14. However, the cross-sectional shape of the tail 44 is a matter of design choice limited only by the shape of the track 57, 58.

The tab 55 is positioned respectively between the switches 24, 26 and the switches 25, 27 and between the front plate 32 and the rear plate 34 of the bar 30 thereof.

As can be seen in Figure 2, as switches 24 and 26 swivel together between the OFF and ON in the direction indicated by the arrow "x" in the Figure 1, the plate 32 engages a rear surface of the head 43. Similarly, as the switches 24 and 26 together swing from the ON to OFF positions in the direction indicated by the arrow "and" in Figure 1 , the fin 55 engages on the inner surface of the faceplate 32. Similarly, the circuit breaker 14 is in the OFF position when the switches 25 and 27 move in the direction of arrow "b" (Figure 1) and in the ON position when tilting in the "a" direction.

(Figure 1) . The plate 32 similarly engages with the rear surface of the head 43 when moving in the "a" direction and will engage the fin 55 when moving in the "b" direction. The connector 40 is disposed in position by placing the switches 24 and 26 in the OFF position as illustrated in Figure 2 and the sliding tail 44 within the track 57 and under the bar 30. The pressure placed on the wing 55 will cause the flex and snap under the front plate 32. The connector 42 is also placed, it being understood that each connector is placed before the respective circuit breakers are mounted on the saddle-shaped base 16. With the above construction, it is now It will be appreciated that both circuit breakers 12 and 14 are inhibited from simultaneously being placed in the ON position with the connectors 40, 42 respectively mounted on the respective rocker switch assemblies. That is, as the connector 40 moves in the "x" direction, its contact with the connector 42 (assuming that the connector 42 is in the ON position) causes the switch assembly of the assembly 14 to move to the OFF position. Also, as the connector 42 moves in the "a" direction, its contact with the connector 40 (assuming that the connection 40 is in the ON position) causes the switch assembly of the assembly 12 to move to the OFF position. However, because the connectors 40 and 42 do not interconnect with each other, it is possible, if desirable, for both circuit breakers 12 and 14 to be simultaneously placed in the OFF position. This can be achieved by the switches 25, 27 moving them in the "b" direction and the switches 24, 26 tilted in the "y" direction. Reference is now made to Figure 5, which represents an alternative embodiment of the present invention. The equal parts in Figure 5 have reference numerals equal to the equivalent parts of Figures 1-4. In this alternative embodiment, the circuit breakers 12 and 14 are similarly mounted and are at least partially covered by a plate 18. The plate 18 includes an opening through which a fastener 72 can be inserted. The fastener 72 is secured to the plate 18. An inhibiting plate 74 (preferably in a triangular shape although this is a design choice) is provided in place of the connectors 40, 42 to inhibit both the circuit breaker 12 and the circuit breaker 14 are placed in the ON position simultaneously. A spacer 75 can be provided on the bottom surface of the plate 74 for proper alignment. The plate 74 will rotate with respect to the fastener 72. In this alternative embodiment, there is no need for the connectors 40, 42 since the rotational nature of the plate 74 achieves the desired result. That is, by virtue of the engagement of a bank 81 of the plate 74 with the switch assembly of the circuit breaker 12 and the engagement of a bank 82 of the plate 74 with the switch assembly of the circuit breaker 14., both circuit breakers 12 and 14 can not be inadvertently placed in their respective ON positions simultaneously. However, it will be appreciated that one of the two circuit breakers 12 or 14 may be in the ON position as long as the other circuit breaker is in the OFF position, while maintaining the possibility that both circuit breakers of circuit are placed in the OFF position simultaneously. Another advantageous feature of the present invention is the ability to add a cover, similar to plate 18, to the invention as illustrated in Figure 1. This cover is installable and removable when the toggle switch assemblies of both circuit breakers 12, 14 are in the OFF position. Reference is now made to Figure 6, which represents an assembly (load center) of eight circuit breakers, generally indicated as 100 and similar to the load center construction 16 shown in Figure 1. The center assembly 100 preferably includes a base made of unitary plastic 105 comprising a plurality of integrally formed ribs 101-105. The ribs 101-105 provide electrical spaces for the circuit breakers (not shown) mounted between them. As shown in Figure 7 (but omitted for simplicity in Figure 6), the base 105 may also include a plurality of integrally-punched terminals 120 disposed between the ribs 101-105. As can be appreciated well now, the prior art constructions needed that in order to ensure that an eight-circuit load center base could have only six circuit breakers mounted therein, it was necessary to cut portions of the punched terminals. This process was expensive and complicated. The base 105 also includes a first sub-assembly extending 160 and a second sub-assembly 162 extending. The subassembly 160 includes a first top surface 161 and the sub-assembly 162 includes a first top surface 163. Integrally extending from the subassembly 160 and 162 and on top surfaces 161, 163 are respective elongate members 141 and 142. Orthogonally extending from the upper edge of elongate member 141 is a plurality of horizontally extending tabs 106-109 and extending orthogonally from the upper edge of elongate member 142 there is a plurality of horizontally extending tongues 110-113. It can be seen in Figures 6-7 that a space is therefore created between the respective upper surfaces 161, 163 and the tabs extending orthogonally. Figure 7 is a cross-sectional view of Figure 6 but with the addition of certain parts, including two circuit breakers which are illustrated for easy understanding of the present invention. Figure 7 illustrates two circuit breakers designated by the reference numerals 166 and 169. A rear hinge 165 of the circuit breaker 166 can be placed in the space provided between the tongue 113 and the top surface 161. In this way, the circuit breaker 166 it is releasably secured to the base 105 in a manner of engagement with the tongue 113 and its line terminal (not shown) connected to its pierced terminal respectively placed. In the case where it is desirable to prohibit a circuit breaker from being electrically connected to the assembly 100, either the perforated terminal placed respectively can be removed (as was done in the prior art discussed above) or the switch is prevented from being secured by the rear tongue respectively placed. The tabs that are closely seen 108 and 109 clearly illustrate these preferred rejection means. The rejection element is preferably an integrally molded block 167, 168 molded into the respective bottom surface of the tabs 108 and 109. As illustrated in Figure 7, a rear hinge 170 of the circuit breaker 169 is prevented from being inserted into the base of the subassembly 105. The process for modeling a plurality of saddle-shaped base configurations for a saddle-shaped assembly of a saddle-shaped base mold, wherein the saddle-shaped assembly includes n perforated terminals for coupling with each first respective end of n automatic circuit breakers (where n in the exemplary arrangement is hatred (8)) and the saddle-shaped base mold is configurable to mold, integrally with the saddle-shaped base, n rear securing elements (in the exemplary example being the rear securing element the tabs in combination with the upper surfaces of the sub-assemblies) to ensure respectively The second respective end of the n circuit-breakers to the saddle-shaped base includes the steps of providing a mold to form the saddle-shaped base of the eight circuit breakers, determining whether it is desirable. ensure that less than eight circuit breakers are mounted therein, and thereafter, integrally mold a selected number of reject elements such as blocks 167, 168 to either the respective tabs or top surfaces of the subassemblies during the molding the base in the form of a saddle to prevent certain circuit breakers from being secured to the base in the form of a saddle. The actual molding process should be well understood by one of skill in the relevant art.

Thus, when using the present invention, it is not necessary to remove the perforated terminal portions in places where it is intended not to have circuit breakers mounted and electrically connected to the assembly 100. This advantage lends itself to considerable cost savings during operation. manufacturing since it is much easier to secure a circuit breaker that can not be inserted into an assembly by providing rejection means such as those described that remove the necessary punched terminals. In this way a load center can be modified in order to accommodate a variant number of circuit breaker configurations without the need for complicated, time consuming and expensive machining modifications. That is, by virtue of a simple modification to the base mold in the form of a saddle, various consumer needs can be efficiently obtained. Reference is now made to Figures 8-11 which represent the last aspect of the present invention, and in particular, an improved rainproof housing construction and method of manufacturing the same. The present invention overcomes the deficiencies provided in the prior art, and in particular, the inability of the state of the box constructions of the state of the art to adequately prevent moisture and other undesirable foreign particles from entering the box along the edges of the box. the same. The present invention achieves this desirable result due to a smoother interface between the edges of the box. The present rainproof housing construction is particularly suitable for housings of circuit breaker assemblies but it should be appreciated that such a housing construction is equally applicable for any other application including industrial applications. Generally speaking, reference is made first to Figure 8 in which the front end, generally indicated at 210, of a box, generally indicated as 200, is shown, constructed in accordance with the present invention. The front end 210 includes a first corner 227 and a second corner 228. The rear end, generally indicated at 220, is not constructed in accordance with the present invention but may if necessary achieve the advantages provided by it. In particular, the box 200 includes the side walls 201, 202, 203, and 206. The overlapping side walls 204 and 205 are also shown. Reference is now made to Figures 9 and 10 for a more detailed description of the present invention. As stated above, in order to build the front end 210 of the box 200 in accordance with the present invention, it is necessary to provide a metal sheet and cut a first slot 230 and a second slot 231 identical in mirror image to the slot 230 therein as indicated in Figure 10. Reference will now be made to the formation of the edges of the box in relation to the slot 230, the opposite edge being constructed identically. With the introduction of the slot 230, the overlapping side wall 205 is formed, being integral with the side 203. The overlapping wall 204 is formed in an identical manner. Reference is now made to Figure 11 for a more detailed description of the slot 230, it being understood that the slot 231 is identically defined. The slot 230 is defined by a plurality of edges, and specifically, a first edge 211, a second edge 212, an inwardly angled edge 213 which extends in an arcuate manner and forms a edge 214 that joins the edge 211. A CNTR center may be established in the arched portion of the slot 230, the arched portion having a radius R. With reference to Figures 8-10, the side walls 201 and 202 are folded up along the fold lines A and E respectively which are parallel to each other and tangent to the respective arcuate edges 214. The overlapping side walls 205 and 204 are bent inward in fold lines B and D, respectively, which are also parallel to each other and tangent to the respective arcuate edges 214. The side wall 203 is bent upwards along the fold line C. This fold is forced to occur along a length of axis with respect to a horizontal centerline to the fold line C at a point that passes through the CNTR center. After that, the overlapping walls 204 can be secured to the side wall 202 and the overlapping side wall 205 can be secured to the side wall 201 as illustrated in Figure 8 with welding, embossing or the like. An area Z (Figure 11) will extend over any hollow on the edges 227 and 228 formed by the respective overlapping side walls. To more adequately illustrate the advantageous nature of the present invention, reference is made to Figure 12. Figure 12 is a view of Figure 8 taken along lines 12-12 and for clarity, only shore 227 is depicted. from the box 200. It can be seen that as the side wall 204 overlaps the side wall 202, any gap that would form along the edge E (Figure 8) is covered by the area Z. Thus, it is prohibits the entry of moisture and other foreign particles into the housing. In the preferred embodiment, the edges 211 and 212 are essentially 0.63 centimeters apart, R is essentially 0.15 centimeters and the thickness of the preferred material is 16 gauge. To compare the present invention with the prior art, reference is made briefly to Figure 13 which illustrates the deficiency of it. That is, seeing the prior art box 300, it can be seen that as the side wall 304 overlaps the side wall 302 (the side walls 304 and 302 correspond to the side walls 204 and 202 respectively) a gap G is formed. in virt \ d of the rectangular slot currently used in building the side walls. That is, using slots 230 and 231 as defined herein, improved box construction is achieved. It will thus be seen that the objects presented above, between the apparent facts of the previous description, are efficiently achieved and, since certain changes can be made in the previous constructions without departing from the spirit and scope of the invention, it is intended that all matters contained in the above description or shown in the accompanying drawings shall be construed as illustrative and in no way limiting. It will also be understood that the following claims are intended to cover all the generic and specific characteristics of the invention described herein and all statements of scope of the invention which is a matter of language could fall between them.
