Definitions
- a tubelike cartridge for mounting an electrical assembly on a panel having an opening therein.
- the cartridge comprises a. pair of telescoping inner and outer sleeves, and a clamping mechanism which is yieldably biased to clamp the edge of the panel opening between the sleeves against the bias thereon.
- One object of the present invention is to provide a small tubelike cartridge of this nature which can be installed in a panel opening and clamped to the edge of the opening by a process conducted on the front side of the panel. Another object is to provide a cartridge of this nature which is self-adjusting when it is clamped to the panel, so as to allow for differences in thickness from one panel to another, caused for example, by differences in mill tolerances or the presence of a paint coating on the panel. A further object is to provide a cartridge of this nature which cannot be overtightened when it is clamped to the panel so as to risk damaging the clamping components which, of necessity, are small and delicate in miniature devices of this nature. Other objects include the provision of a cartridge of this nature which is highly durable in construction and has a relatively small number of readily interchangeable parts that are cheaply manufactured and easily assembled with one another. Still further objects will become apparent from the description of the invention which follows hereafter.
- a small tubelike cartridge of our invention which comprises a pair of telescoping inner and outer sleeves, and a clamping mechanism which is yieldably biased to clamp the edge of the panel opening between the sleeves against the bias thereon.
- the clamping mechanism comprises a pair of relatively shiftable stops which are yieldably biased in the opposite endwise directions of the sleeves, and an adjustable clamping means which is operative to clamp the edge of the opening between the sleeves against the bias on the stops.
- the stops are coaxially aligned with the sleeves and are yieldably biased at a plurality of peripherally distributed points thereon which are symmetrically disposed about the cross-sectional area of the sleeves so as to balance the clamping forces on the edge of the opening.
- one of the stops is rigidly carried on the inner sleeve and the other is slidable therein; and the clamping means is operatively interconnected with the slidable stop and the outer sleeve to apply the clamping forces in the opposite endwise directions thereof, there being an outtumed flange on the projecting forward end portion of the inner sleeve which is coopetable with the outer sleeve to clamp the edge of the panel opening therebetween.
- the slidable stop comprises a floating compression block which is adapted for mounting electrical components of the assembly in the sleeves.
- the block is slidably engaged in the inner sleeve and yieldably biased in the open end direction of the cartridge by a plurality of peripherally distributed resilient compression elements caged between the block and an equal number of rigid stops on the sleeve.
- the base is detachably connected with the rear end portion of the outer sleeve, and in the clamping process, the rotation of the screw operates to clamp the base against the end of the sleeve, when the edge of the opening is clamped between the flange on the inner sleeve and the adjacent forward end of the outer sleeve.
- the travel of the block is limited by a pair of stops on the screw and the inner sleeve, between the block and the base, and the block and the open end of the cartridge, respectively.
- the clamping screw has an Allen head socket therein, and the socket has a circumferential lip formed about the mouth thereof to cooperate with the latch mechanism of a pushbutton cap such as is disclosed in our copending application Ser. No. 826,962 filed on even date herewith.
- FIG. I is a part cross-sectional view of the cartridge in mounted position on a panel
- FIG. 2 is a part cross-sectional view of the cartridge in mounted position on a panel of greater thickness
- FIG. 3 is an exploded perspective view of the cartridge illustrating the various components therein.
- the cartridge 2 comprises a pair of rectangular metal sleevelike tube sections 4 and 6 which are telescopically engaged in one another.
- the inner sleeve 4 has an out-tumed flange 7 on the open forward end portion 4' thereof, and several cutouts 8 and I0 and crimpings 12 in the rear end portion 4 thereof.
- One of the cutouts takes the form of a short axially extending slotlike indentation 8- in the rear end of the sleeve; while the other two are in the form of U-shaped corner cutouts I0 which form bendable tabs 14 in the sidewalls of the sleeve.
- the crimpings are also developed at the rear end of the sleeve, where the corners are inwardly crimped to form a set of stops I2 the function of which shall be explained shortly.
- the outer sleeve 6 has a rectangular opening 16 in one of the larger dimension sidewalls thereof; and a pair of wide groovelike recesses I8 in the rear end edges of its narrower sidewalls.
- the cartridge also comprises a floating insulative ceramic compression block 20 which is slidably guided in the inner sleeve 4 and yieldably biased in the direction of the open end 4' of the cartridge.
- the block has three spaced, mutually parallel and transversely aligned bores 22 therethrough, the outer two 22 of which have a pair of spring loaded electrical contacts posts 24 mounted therein.
- the center bore 22" is disposed on the axis of the block and is adapted to receive a specially devised Allen head screw 26 which has an elongated, stepped cylindrical head 26' thereon, that in turn, has a stepped deeply recessed socket 28 therein.
- the screw is inserted in the block until the wider diameter shoulder 30 thereon abuts the upper end face 20' of the block; whereupon the threaded tip 32 of the screw projects well below the lower end face 20" of the block for interengagement with the base 34 of the cartridge as shall be explained.
- One of the posts 24 also has a projecting tip 24' thereon which makes contact with an apertured printed circuit board 36 in the base, there being a bus bar connection (not shown) between the posts which enables them to be conjointly energized from the board.
- the compression block is also structurally developed in two other regards.
- An axially extending groove 38 is formed in one sidewall of the block from the rear end thereof; and each of the corner portions 39 of the block is relieved well along the axial length of he block from the rear end thereof, so that the comer shoulders 40 of the end are deeply inset therefrom.
- a set of peripheral cages 42 are formed in the corners of the sleeve which can house an equal number of coiled springs 44 that are inserted therein on capped guide pins 46.
- the caps of the pins rest on the erimped stops 12 formed at the lower end of the sleeve, and thus interengage the springs between the stops and the shoulders 40 of the block.
- the base 34 of the cartridge has a large rectangular recess 48 in the body thereof, and the periphery of the recess is rabbetted to form a supporting shoulder 50 for the circuit board 36 at approximately midway into the recess.
- the larger dimension sidewalls of the base and the adjoining corners of the narrower walls are also relieved to form a pair of broadly dimensioned tongues 52 which project from the end edges of the base.
- the tongues are sized to interengage with the groovelike recesses 18 in the end edges of the outer sleeve; and in addi-- tion, an axially extending rib S4 is formed within the recess 48 of the base, on one of the tongued walls of the same.
- the rib is sized to interengage with the groove 38 and the slot 8 in the compression block and the inner sleeve.
- a raised cylindrical column 56 At the center of the recess, on the axis of the base, there is a raised cylindrical column 56, and the column in turn has a cylindrical bore 58 therein which passes through the base.
- the bore is adapted to receive a flanged clamping nut 60 which is inserted into the bore 58 from the rear of the base until the flange 60' abuts against the end face 34' thereof.
- a rectangular terminal plate 62 is secured over the face, as by means of a set of fixed terminal posts which are omitted from the drawing as not being material to the invention described herein.
- terminal posts are connected with the circuit board 36 and the assembly is retained on the shoulder of the recess by passing the nut through an aperture 64 in the board and flaring the unthreaded forward end 60" of the nut 60 until it flanges over the board and clamps it against the top of the column 56.
- the bottommost portion 28' of the socket 28 in the screw 26 has a characteristic Allen head cross section therein, for purposes of engaging the longer arm of an Allen head wrench therewith.
- the inner sleeve is passed through the opening 72 therein from the front side 70' of the panel, and the outer sleeve 6 is then slipped over the inner sleeve 4 from the other side 70" of the panel and abutted thereagainst.
- the base 34 it is interengaged in tongue and groove fashion with the grooved end 18 of the outer sleeve, and the tip 32 of the screw is interengaged with the clamping nut 60.
- thercon--the difference in thickness is taken up in the compression of the springs 44 as seen by a comparison of H65. 1 and 2.
- H0. 2 the greater thickness of the panel requires that the block disengage from the tabs 44 and move deeper into the cartridge from the flange, against the bias on the springs.
- a tubelike cartridge for mounting an electrical assembly on a panel having an opening therein comprising a pair of telescoping inner and outer sleeves, and a clamping mechanism comprising a pair of relatively shiftable stops which are rigidly carried on and slidable in the inner sleeve, respectively, and yieldable biased in the opposite endwise directions of the sleeves, and an adjustable clamping means which is operative to clamp the edge of the panel opening between the sleeves against the bias on the stops.
- stops are coaxially aligned with the sleeves and are yieldably biased at a plurality of peripherally distributed points thereon which are symmetrically disposed about the cross sectional area of the sleeves so as to balance the clamping forces on the edge of the opening.
- clamping means is operatively interconnected with the slidable stop and the outer sleeve to apply the clamping forces in the opposite endwise directions thereof, there being an out-turned flange on the projecting forward end portion of the inner sleeve which is cooperable with the outer sleeve to clamp the edge of the opening therebetween.
- the slidable stop comprises a floating compression block which is adapted for mounting electrical components of the assembly in the sleeves.
- the cartridge according to claim 6 having a base carried on the rear end portion of the outer sleeve, and wherein the clamping means includes a clamping screw which is rotatably mounted at a central location in the block, and interengaged with a threaded bore in the base.
