Definitions
- ABSTRACT A terminal block assembly wherein the electrical connection is broken, and the blocks are separated, by pivoting or rolling one block apart from the other.
- the terminal block assembly includes first and second terminal blocks, each block having one side adapted to engage and mate with one side on the other block.
- One edge on one block defines a roll axis.
- An opposing surface on the other (usually mounted) block defines a fulcrum. The fulcrum surface engages the roll axis when the one block is rolled or pivoted apart from the other block to pivot its mating side away from electrical connection with the other block.
- the present invention relates to a new and improved terminal block assembly wherein the blocks are separated by rolling one block apart from the other block.
- terminal block assemblies comprised of first and second terminal blocks having mating terminal connectors mounted on one side of each of the blocks.
- terminal connectors on one side of one block are female terminal connectors and the terminal connectors on one side of the other block are male terminal connectors adapted to frictionally engage the female terminal connectors.
- the terminal blocks are held together in assembled position by reason of the frictional engagement between the respective terminal connectors thereon.
- one of the blocks is fastened inside a metal cabinet or other type of junction box and wire conductors are connected to each one of the terminal connectors on the mounted block. Then wire conductors are connected to each of the terminal connectors on the other block and the other block is forced into mating frictional engagement with the mounted block.
- wire conductors are connected to each of the terminal connectors on the other block and the other block is forced into mating frictional engagement with the mounted block.
- the present invention provides for the rolling apart of one terminal block from a mounted terminal block. In this way a rolling or torque force is utilized in separating the terminal blocks as opposed to a linear pulling force and, accordingly, it is a primary object of the present invention to provide such a roll-apart terminal block assembly.
- It is another object of the present invention to provide a roll-apart terminal block assembly including first and second terminal blocks with each block having one side thereof which is adapted to mate with the one side of the other block, the respective mating sides extending between two edges of the respective blocks with one edge on the first block defining a roll axis and the surface areas adjacent the complementary opposite edge on the second block defining fulcrum surface areas on which the one edge defined in the roll axis pivots and slides when the first block is rolled apart from the second block.
- It is a further object of the present invention to provide a roll-apart terminal block assembly including the two blocks with each block having one side thereof which is adapted to mate with the one side of the other block, one edge on one block defining a roll axis and the marginal surface areas on the mating side of the other block adjacent the edge complementary and opposite the roll axis defining a surface which engages the roll axis when the other block is rolled apart from the one block having the edge defining the roll axis.
- FIG. 1 is an end elevational view of a prior art pullapart terminal block assembly
- FIG. 2 is an end elevational view of the roll-apart terminal block assembly of the present invention
- FIGS. 3a, 3b and 3c are end elevational views of the roll-apart terminal block assembly of the present invention as one block is being rolled apart from the other block;
- FIG. 4 is an enlarged end elevational view of the separated terminal blocks of the roll-apart terminal block assembly of the present invention
- FIG. 5 is a side elevational view of the separated terminal blocks of the roll-apart terminal block assembly of the present invention.
- FIG. 6 is a plan view of the mating sides of the terminal blocks of the roll-apart terminal block assembly of the present invention placed side-by-side;
- FIG. 7 is a vertical sectional view of the terminal block assembly of the present invention taken generally along the line 7-7 of FIG. 5 when the separated terminal blocks in FIG. 5 are brought together in mating engagement.
- a pior part pull-apart terminal block assembly is generally indicated at 3 in FIG. I and includes first and second terminal blocks 5 and 7 which are adapted to be pulled apart in a direction indicated by the arrows 8 and 9.
- first and second terminal blocks 5 and 7 which are adapted to be pulled apart in a direction indicated by the arrows 8 and 9.
- one block, such as the block 5 is fixed and only the block 7 is pulled apart from the block 5 in the direction indicated by the arrow 9.
- Each of the terminal blocks, such as terminal blocks 5 and 7 includes mating contact means which frictionally engage each other when the terminal blocks are brought together to form the terminal block assembly. Then when it is desired to disconnect one block from the other block, one of the blocks such as the block 7 is pulled apart from the other block 7, against the frictional force holding the blocks together.
- the present invention overcomes these deficiencies by providing a terminal block assembly .which is adapted to be rolled or pivoted apart.
- the roll-apart terminal block assembly of the present invention is generally indicated at 10 in FIG. 2 and includes first and second blocks 12 and 14.
- the block 12 is mounted on a surface 16 which is typically a panel of a cabinet or junction box.
- the terminal block assembly can be mounted in a reverse or opposite manner by mounting the terminal block 14 to the panel or other surface as indicated by broken lines at 18.
- the mounting of the first terminal block 12 to a surface such as the surface 18 is preferred.
- FIGS. 3a-3c show block 12 in various positions with respect to block 14 as it is rolled apart from or pivoted with respect to the second block 14, and of course, either block 12 or 14 could be attached, the other block being rolled or pivoted for separation.
- the block 12 has one side 18 which is adapted to mate with one side 20 of the block 14 and in this respect the sides 18 and 20 have mating configurations as now will be defined in detail. From a consideration of the illustration of block 14 in the drawings, it will be apparent that the one side 20 extends between two edges 22 and 24 and that there are marginal surface areas 26 and 28 which extend along and inwardly of the block 14 from the edges 22 and 24. In the illustrated embodiment these marginal surface areas 26 and 28 are shown as lying in the same plane although this is not essential.
- the second block 14 has at least one projection 30 extending outwardly from the plane containing the marginal surface areas 26 and 28.
- the projection 30 has a top side 32 and first and second inclined side walls 34 and 36.
- the side wall 34 inclines upwardly to the top side 32 from the marginal surface area 26 along a line spaced from and parallel to edge 22 and forms an obtuse angle with the plane of the marginal surface area 16.
- the side wall 36 extends from the plane containing the marginal surface area 28 along a line parallel to and spaced from the edge 24 to the top side 32. This side wall 36 also forms an obtuse, but smaller, angle with the plane containing the marginal surface 28.
- the junction between the sidewall 36 and the top side 32 is rounded as indicated at 38.
- the projection 30 has a rib 40 extending from the top side 32.
- the block 14 is provided with a guide pin 42 which extends from the marginal surface area 28.
- the block 12 includes at least one recess 50 which is defined by a bottom wall 52 and side walls 54 and 56 which are inclined so that the recess 50 has a configuration which is complementary to the configuration of the projection 30 and so that the recess 50 is adapted to receive the projection 30 therein as best shown in FIG. 2.
- the mating side 18 of the first block 50 extends between two edges 62 and 64 on the first block and the mating side 18 of the first block 12 has marginal surface areas 66 and 68 which lie in the same plane and which extend inwardly of the first block 12 from the edges 62 and 64 thereof.
- the side wall 54 extends inwardly from the marginal surface area 66 along a line parallel to and spaced from the edge 62 with the junction between the side wall 64 and the marginal surface areas 66 defining an edge 69.
- the first terminal block 12 has at least one male terminal connector 74 which is adapted to mate with at least one female terminal connector which is hidden from view in FIG. 4 and which is generally indicated at 76 in FIG. 6. Also the block 12 has a guide pin receiving opening 80 which is hidden from view in FIG. 4 and which is best shown in FIG. 7. Additionally the bottom of the recess 50 has a slot therein hidden from view in FIG. 4 which is shown at 82 in FIG. 7 and which is adapted to receive the rib 40 therein.
- one edge 62 of the terminal block 12 is characterized as the first roll axis, i.e., the roll axis for block 12 when it is pivoted to be separated from mounted block 14, and edge 22 is a second roll axis, i.e., the axis about which block 14 rolls when block 14 is pivoted to separate it from mounted block 12.
- the marginal surface area 26 on the second block 14 can be characterized as a sliding fulcrum surface against which axis 62 bears, and marginal surface 66 can be considered a fulcrum against which axis edge 22 can bear.
- Block 12 can be rolled or pivoted away from the block 14 by pivoting about roll axis 62. Then as the block 12 is rolled apart from the block 14 the roll axis 62 will usually slide as well as pivot on the fulcrum surface area 26 as best shown in FIG. 3b. Then, as and when the frictional engagement between the male contact 74 and the female contact 76 is broken the marginal extending portion 48 will usually engage and slide against the inclined side wall 34 as best shown in FIG. 3c.ln this way a smooth roll-apart disconnection between the first and second terminal blocks 12 and 14 is obtained with the terminal block assembly 10 of the present invention.
- the particular configuration of the sides 18 and 20 of the first and second blocks 12 and 14 facilitate this smooth roll-apart disconnection.
- the inclining of the side wall 36 of the projection 30 and the side wall 56 of the recess 50 plus the rounding of the junction between the top side 32 and the side wall 36 as well as the junction between the side wall 56 and the bottom wall 52 provides for a smooth mating and separating of the terminal blocks 12 and 14.
- FIGS. 3a, 3b and 30 An important aspect of the mating engagement between the blocks 12 and I4 is the cooperation between the roll axis 62 and the fulcrum surface area 26 which is readily apparent in FIGS. 3a, 3b and 30. Of secondary importance is the sliding engagement between the extending portion 48 and the inclined side wall 34 of the projection 30. In this respect it will be apparent from FIG. 3 that there are two points of sliding and pivoting engagement between the blocks 12 and 14 as complete separation is effected. Namely, there is sliding and pivoting engagement between the roll axis 62 and the marginal surface area 26 and between the first secondary roll axis 69 and the side wall 34. This preferred provision of two points of sliding and/or pivoting engagement between the blocks 12 and 14 facilitates the smooth roll-apart separation of the blocks 12 and 14 in the manner just described.
- the block 14 can pivot about the edge 62 (and finally, possibly around edge 69) as the block 14 is rolled apart from the block 12.
- the marginal surface area 26 will ordinarily slide on and about the roll axis 62 and the side wall 34 will slide on and about the roll axis 69.
- the electrical connectors 74, 76 slide in an arcuate path with respect to each other, and the adjacent structures in blocks l2, 14 must be of such a configuration that the arcuate relative motion of theconnector means is not obstructed.
- the invention is not to be limited as to the provision of only one roll or pivot axis, or only one means for rolling or pivoting the blocks apart 'to separate the sliding connectors.
- the block 14 has at least one projection 36 and the block 12 has at least one recess 50.
- each block 12 and 114 is generally rectangular in shape and has several-projections and/or recesses as best shown in FIGS. 5-7.
- FIG. 5 it will be apparent that in the illustrated embodiment the second block 14 has four of the projections 30 which are separated and equally spaced apart by three identical cavities 84 in the block 14.
- Each of the cavities 84 opens ontothe one side 18 of the block 14 and in the illustrated embodiment also opens onto a second side 86 of the block 114 which is adjacent to the side 20 and which intersects the plane of the marginal surface areas 26 to form the edge 62.
- each of the female connectors 76 also includes a lug and set screw assembly 90 as best shown in FIG. 5. It will be apparent from FIG.
- the block 14 is provided with three openings 92 which open onto the second side 86 of the block 14 which are adapted to receive and hold each one of the lug and set screw assemblies 96 and which provide access means for wire conductors so that wire conductors can be inserted into the block and secured to the lug and set screw assemblies of each of the terminal connectors 75.
- the marginal surface area 28 is continuous and is not interrupted by the cavities 84.
- the areas between the projections 30 and upwardly from the continuous marginal surface area 28 is open to provide a space to accomodate wire conductors connected to the male terminal connectors 74 mounted on the block 12 when the blocks 12 and 14 are in assembled position.
- the recesses 50 are spaced apart and separated by channels 96 each of which extends between opposite sides 98 and of the block 12 which extend to the mating side 18 and intersect the plane of the surface areas 66 and 68. Also since the channels 96 extend completely across the one side 18 of the block 12 the surface areas 66 and 68 are discontinuous and are in effect surface area sections.
- each of the male connectors 74 is mounted in one of the channels 96 and as best shown in FIGS. 5 and 6 each of the male connectors 74 is generally box-shaped with a set screw 104 threadedly received within the box portion of the male connector 74. It will be apparent from FIGS. 5 and 6 that a wire conductor can be inserted into the channel 96 for being received and secured to the male connector 74 from either side 98 or 100 of the terminal block 12.
- the channels 96 extend completely across the block 12 and open onto the sides 98 and 100 of the block 12.
- the frictional engagement of connectors 74, 76 should be firm enough to assure that the connectors wont separate until manually pivoted or pulled apart.
- two counterbored through bores 108 are provided in the block 12 and for securing the blocks 12 and 14 together after they have been pressed together into assembled position.
- two counterbored through bores 108 are provided in the block 12 and capitad through bores llltl are provided in the block 14. If the block 14 is to be mounted on a panel or surface the through bores 110 can be counterbored for receiving the heads of mounting screws or nuts on a stud which extends through both blocks 12 and 14.
- a roll-apart connect-disconnect terminal block assembly including separable first and second blocks, at least one first electrical contact means on one side of said first block, mating second contact means on one side of said second block for frictionally engaging said first contact means on said first block when said blocks are brought together, said one side of said first block having a recess configuration adapted to mate with a projection on said one side of said second block, said one side of said first block extending between two edges of said first block, one of said edges defining a roll axis, said one side of said second block extending between two edges and having marginal surface areas thereon adjacent one edge thereof between said edge and said projection, said surface areas defining a fulcrum surface which engages said one edge of said first block defining said roll axis when said blocks are in a fully engaged position, said edge and said surface remaining in contact when one of said blocks is pivoted with respect to said other block around said axis, said first and second contact means being moved in an arcuate path with respect to each other as they disengage as said first
- said projection has a side wall which faces generally toward said one edge of said second block and which lies in a plane of said marginal surface area, said recess in said first block being defined in part by a side wall which extends into said one side of said first block along a line parallel to and spaced from said one edge and which forms an obtuse angle with said one side of said first block, the junction between said one side of said first block and said recess side wall along said line defining an edge of said recess which slidingly engages said side wall of said projection when one of said blocks is being rolled apart from the other of said blocks.
- one of said blocks has a guide pin extending from said one side thereof and said other block has a guide pin receiving opening in said one side thereof which is slightly larger than said guide pin and which is adapted to receive said guide pin therein.
- said projection has a blunt end defined by a top wall and has a rib extending from said top wall, and said recess has a bottom wall with a slot therein adapted to receive said rib.
