In an exemplary embodiment, as illustrated in
A load terminal screw 26a and common terminal screws 28a and 28b are disposed on a first side of the bottom housing 14. Similar load terminal screws 26b and 26c are disposed on the opposing side of the bottom housing 14, along with a ground screw 30, as is shown in
The components of the combination device 10 include receptacle outlet components 34, switch components 36, and an assembly screw bore 38.
The receptacle outlet and switch components 34, 36 are described with reference to exemplary embodiments shown in
The switch components 36 include the toggle 24, common terminal 42, a cradle 56, a flipper 58, a spring 60, and switch terminals 62a, 62b. Load terminals 64a, 64b, including backwire clamps 50c, 50d and the load terminal screws 26a, 26b, electrically communicate with the switch terminals 62a, 62b.
The cradle support post 68a includes a low wall 76 forming a gap at one side of the boundary level 70 that allows a portion of the cradle 56 to extend to and interface with the common terminal 42, as is described further below. Adjacent the cradle support post 68b, the housing includes a portion formed as rubber bumpers 78 configured to dampen and cushion movement of the toggle 24.
Turning now to
The outlet portion 80 includes the second receptacle contacts 52 described above. It should be noted however, that other configurations of the second receptacle contacts 52, as well as the first receptacle contacts 46, are contemplated. The switch portion 82 includes a main wall 86, a slip receiver 90, and a bend (not shown) connecting the main wall and the slip receiver. In this embodiment, the main wall 86, the bend, and the slip receiver 90 are all formed of a single conductive sheet, stamped and formed to create the common terminal 42. The main wall 86 includes an upper edge 92, a side edge 94, and a screw receiving portion 96, such as an aperture or a slot, for receiving the common terminal screw 28a. In the embodiment shown, the slip receiver 90 connects to the main wall 86 at the bend and extends at an angle between 70° and 90° from the main wall 86. Accordingly, the bend may form up to a right angle. In other embodiments, other angles both larger and smaller are contemplated. In this embodiment, the main wall side edge 94 extends less than the total height of the main wall 86, with the side edge 94 ending at the bend. The slip receiver 90 is configured to cooperate with the cradle 56 to form a slip connection. In this embodiment, the slip receiver 90 is U-shaped and includes a first wall 98 connected to the bend and a second wall 100 configured to lie adjacent the first wall 98. The first and second walls 98, 100 may be formed of a single plate and bent to form the U-shaped slip receiver 90, thereby forming an integral bridge 99 between the first and second walls 98, 100. Accordingly, the second wall 100 is not attached at its sides to the main wall, but instead connects to the first wall 98 only at the bridge 99. In this embodiment, the second wall 100 is disposed closer to the screw receiving portion 96 than the first wall 98, and the second wall includes a first portion 101 and a second portion 102. The first portion 101 is formed to be substantially parallel to the first wall 98 and is spaced a first distance from the first wall 98. The second portion 102 extends from the first portion 101 and also is substantially parallel to the first wall 98. The second portion 102 is spaced a second distance from the first wall 98, with the distance from the first portion 101 to the first wall 98 being greater than distance from the second portion 102 to the first wall 98. Upper edge portions 103a, 103b of the first and second walls 98, 100 diverge and are flared to receive a connecting component, such as a portion of the cradle 56, as is described below.
An exemplary embodiment of the cradle 56 is shown in greater detail in
The connecting portion 106 is a plate-like, rectangular-shaped conductor configured to interface with the common terminal 42. It extends downwardly, well below the level of the body portion 104, so that it extends away from the body portion 104 and the transition portion 108. The transition portion 108 extends from an upper portion 122 of the connecting portion 106 to one side of the body portion 104. When in the bottom housing 14, the transition portion 108 extends through the gap formed over the low wall 76 in the cradle support post 68a (
Inserting the connecting portion 106 within the U-shaped slip receiver 90 provides electrical communication between the common terminal 42 and the cradle 56. This arrangement allows displacement of the connecting portion 106 relative to the common terminal 42, while still maintaining the electrical connection. The connecting portion 106 can be moved in any direction along its plane relative to the slip receiver 90, including longitudinally and laterally. Because the connection is not fixed, the cradle 56 may be oriented and manipulated to fit properly within the outer housing 14 on the cradle support posts 68 while still maintaining a solid mechanical and electrical joint with the common terminal 42. This also gives leverage to adjust the cradle 56 in the bottom housing 14.
In other embodiments, the common terminal includes the connecting portion and the cradle includes the slip receiver. In some such embodiments, the slip receiver may be flipped so that the receiving portion is introduced into the slip receiver from a bottom portion, rather than from a top portion, as described. Other arrangements are contemplated.
The bridge 128 includes a centrally disposed electrical contact 134. It extends through the bridge 128 and is configured to make an electrical connection on either the front side of the flipper 58 or the opposing back side (not shown). In the embodiment shown, the electrical contact 134 is a double-sided silver contact rivet. The bridge 128 includes a spring interface portion 136 protruding upwardly between the arms 126. The spring interface portion 136 has a width W1 at a base 138 and a width W2 at a central region 140. The flipper is configured to rock within the cradle to move into and out of contact with the switch terminals 62a, 62b. This is explained in greater detail below.
The spring 60 interfaces with the flipper 58 and the toggle 24. One end 142 attaches over the spring interface portion 136. The spring 60 has a diameter that elastically deforms to fit over the central region 140 and that fits closely over the base 138. Accordingly, the spring 60 may be placed over the spring interface portion 136 during assembly and held in place by the central region 140 by interference.
One exemplary embodiment of the toggle 24 is described with reference to
A flange 160 protrudes outwardly from the relatively long and short sides 156, 158. This flange 160 is configured to cooperate with the top housing 12 to restrict or limit visibility into the housing so that any arcing and sparking within the housing is less visible to a person flipping the toggle 24. The flange 160 protrudes outwardly from a bottom edge 159 (
The switching elements 154 interface with the top housing 12 and the switch components 36 to operate the switch 22. The switching elements 154 include pivot pins 162, a rotation limiter 164 having stop surfaces 166, side wall portions 168, and a protruding spring interface portion 170. The side wall portions 168 extend generally within a same plane as the long sides 156 of the base portion 152, along opposing sides of the spring interface portion 170. A cutout 172, extending toward the lever portion 150, is included in the side wall portions 168 and is sized to receive at least a portion of the arms 126 of the flipper 58.
The pivot pins 162 extend outwardly from the side wall portions. The pivot pins 162 are cylindrical protrusions extending from opposing sides of the toggle 24 and are configured to interface with the top housing 12 to pivotally secure the toggle 24 in its operative position. The rotation limiter 164 extends on either side of one of the pivot pins 162, and the stop surface 166 is configured to interface with the rubber bumpers 78 in the bottom housing to limit the amount of rotation of the toggle 24.
The spring interface portion 170 protrudes out of the base portion 152 away from the lever portion 150 and is configured to interface with an end 174 of the spring 60. The spring interface portion includes a center protrusion 176 and a shoulder portion 178. The end 174 of the spring 60 extends around the center protrusion 176 and rests on the shoulder portion 178. Reinforcement portions 180 extend along at least a part of the spring interface portion.
As best seen in the exemplary embodiment in
In the exemplary embodiment shown in
In use, the toggle 24 is inserted through the toggle aperture 182 in a manner to limit the visibility through the toggle aperture 182. When flipped, the toggle 24 pivots about the pivot pins 162, which are secured relative to the top housing 12, until the rotation limiter 164 stops the movement of the toggle 24. During rotation, the flange 160 moves to interface with the interfacing surface 194 of the top housing 12. In some embodiments, the flange 160 comes into contact with the top housing 12, while in other embodiments, it is disposed not in contact with the top housing 12, but still limits visibility into the top housing 12 between the toggle 24 and the top housing 12.
Along the long sides 156 of the toggle 24, the flange 160 need not interface directly with the top housing 12 to limit visibility into the combination device 10, but its location along the toggle 24 at least partially blocks the view into the housing 12 along the toggle long side 156. This occurs because the aperture length L2 and the aperture width W2 are less than the toggle length L1 and width W1. In embodiments employing the exemplary toggle in
When the toggle 24 is moved to the left as shown in
The combination device 10 may be assembled by sliding the common terminal 42 into the bottom housing 14 so that the outlet portion 80 of the common terminal 42 is in the outlet portion of the bottom housing 14 and the switch portion 82 of the common terminal 42 is in the switch portion of the bottom housing 14. The switch terminals 62a, 62b and the receptacle terminal 40 also may be inserted into the bottom housing 14 in their proper locations. The cradle 56 may then be introduced to the bottom housing 14 so that it rests on the cradle support posts 68. The cradle troughs 120 may be disposed within the receiving levels of the cradle support posts 68. The boundary levels 70 of the cradle support posts 68 assist by restricting lateral or longitudinal movement of the cradle 56 relative to the bottom housing 14. While inserting the cradle 56, the connecting portion 106 may be inserted into a top of the slip receiver 90 on the common terminal 42. This provides a secure, reliable electrical connection between the cradle 56 and the common terminal 42, but also allows the cradle 56 to be manipulated independently of the common terminal 42. Therefore, the cradle 56 may be manipulated to fit as desired relative to the cradle support posts 68 without affecting the position of the common terminal 42. This may help achieve better fits and may provide more reliability and consistency for flipper operation as it is partially dependent upon the fit of the cradle 56.
Once the cradle 56 is properly placed and connected to the common terminal 42, the spring 60 is placed over the spring interfacing portion 136 of the flipper 58. Because the spring interfacing portion 136 includes a central region 140 that is wider than the base region 138, the spring 60 may elastically deform to fit over the central region 140. The spring 60 and flipper 58 are then introduced through the central aperture 114 of the cradle 56 so that the flipper 58 is suspended by its arms, of which the cradle interfacing edges of the flipper 58 are disposed within the troughs 120. This provides the flipper 58 with the capability to rock back and forth to come into and out of contact with the switch terminals 62a, 62b.
The toggle 24 may then be placed within the upper housing 12 and the upper housing 12 and the toggle 24 may then be introduced to the bottom housing 14. During this process, the spring interface portion 170 of the toggle 24 is oriented to interface with the spring 60. Doing so, the center protrusion 176 of the spring interface portion 170 extends into the coil spring 60 and the shoulder portion 178 contacts and supports the spring 60. As the top housing 12 and toggle 24 are brought closer to the bottom housing 14, the spring 60 compresses, providing a spring force against the flipper 58 and the toggle 24. Once the top housing 12 is in place, the mounting strap 16, or other system, may be used to securely couple the top and bottom housings 12, 14 together. The terminal screws and backwire clamps may be attached at any time throughout the process.
