BACKGROUND OF THE INVENTION I This invention relates to terminal block assemblies and more particularly, to a terminal block assembly having snap-in electrical connector components providing an easily assembled positive connection terminal block.
Most prior art terminal blocks have been constructed from porcelain and the metallic electrical connector members are secured thereto by nuts and bolts or the electrical connectors are secured between separate sections of the terminal block by bolting the terminal block halves together around the metal electrical connectors. In thepast, many terminalblocks required that the individual wires be connected thereto by such means as soldering, brazing, riveting or by use of threadable bolt connectors.
Assembly of theprior art terminalblocks has been a time consuming and sometimes intricate operation. Additionally, connecting the wires through the terminal block has also been a time consuming process and has required special tools at the installation site. The need for a terminal block which would permit both rapid assembly of the terminal block itself and which would have a facility for the rapid connection of wires through the terminal block has existed for many years particularly in such equipments as streetlighting luminaires where maintenance repair and even initial assembly may be required to be performed under inclement or otherwise undesirable weather conditions. Speed, simplicity and a minimization of the number of tools required in performing the functions of assembly and electrical connection is therefore a highly desirable characteristic not heretofore available in terminal blocks.
SUMMARY OF THE INVENTION The terminal block assembly of this invention provides for the quick and simple assembly and electrical connection of a terminal block with a minimum of tools by providing a block of insulating resinous material having a plurality of parallel tunnels extending therethrough and a plurality of apertures communicating with the tunnels, electrical connector means are releasably retained in the tunnels and clamping means is threadably mounted in the apertures and extends into the tunnels to coact with the electrical connector means to secure an electrical conductor therebetween. The electricalconnectors combine into one piece a primary terminal and a plurality of secondary terminals without the need for soldered, brazed, riveted or contact junctures between the primary and secondary terminals which could cause high resistance locations.
BRIEF DESCRIPTION OF THE DRAWING side of the terminal block of this invention;
FIG. 2 is a top plan view of the terminal block assembly of FIG. 1;
FIG. 3 is a sectional view taken along the line III-III of FIG. 1; i
FIG. 4 is a sectional view taken along the line IV--IV of FIG. 3;
FIG. 5 is a sectional view taken along the line VV of FIG. 2; and
FIG. 6 is an exploded view of the terminal block as sembly of this invention illustrating the various parts and their relationships.
DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now in detail to the drawing wherein like reference characters represent like parts throughout the several views, there is illustrated in the exploded view of FIG. 6 the parts incorporated in the terminal block assembly of this invention. The terminalfblock assemblygenerally designated 10 includes a block 12 constructed from a resinous insulating material such as- As best illustrated in-FIGS. l, 3 and 4, the tunnels l4 7 in a front view have a T-shaped configuration, the top a slot of which extends for approximately half the depth of the tunnel and is constructed to dimensions which receive and retain the speed nut 16 therein. As seen in FIG. 3, when the speed nut 16 is fully received within the top portion or cross slot of the T, the threaded aperture of the speed nut is axially aligned with the center of the intersecting counterbored aperture 20. At approximately the same point, in the tunnel where the counterbored passage 20 intersects the tunnel, there are reduced diameter wall portions 24 in the form of ini ternal ribs which serve to coact with the lances 26 and tabs 28 on the exterior sides of the U-shaped conversion terminal 18 to releasably retain the U-shaped conversion terminal at a predetermined position within the tunnel 14. The interaction of the lances 26 and tabs 28 with the reduced diameter wall portions or ribs 24 of the tunnel 14 is best illustrated in FIG. 4.
The terminal block 12 also includes a pair of side flange members 30 which are utilized to mount the terminal block assembly 10 to a suitable structural portion of the equipment in which the terminal block assembly is employed. Securing of the terminal block to the equipment may be accomplished by bolting through the holes 32 in the flanges 30. The flanges 30 also may carry, where desired, auxiliary terminals. Auxiliary terminals such as the U-shaped auxiliary terminals 34 may be snapped into and releasably retained by the square apertures 36 in the flange 30. The U-shaped auxiliary terminals 34 include tabs 38 and lances 40 which serve to retain the auxiliary terminal in the aperture 36 as best illustrated in FIG. 5.
As will be apparent, the terminal block assembly of this invention can be simply and quickly assembled by hand without the use of any tools and connecting the wires to the terminal block assembly can also be performed with only the use of a simple screw driver. The
quick and simple toolless assembly can be performed because the plastic insulating material, such as for example .asbestos filled polyester, is slightly deformable unlike the rigid ceramic or porcelain material commonly used in terminal block assemblies and when combined with the resilient metal tabs on the components snap-in retention is accomplished.
In assembling each of the terminals in the tunnels 14, the speed nut 16 is slid into the top slot of the T-shaped opening until the edge of the nut abuts the back wall of the slot and the threaded aperture of the speed nut is aligned with the counterbored aperture 20. The U- shaped conversion terminal is then pushed into the tunnel until the tabs 28 slip beyond the reduced diameter portion 24 and the lances 26 abut the reduced diameter portion, thus retaining the conversion terminal 18 securely in the tunnel 14. The slotted set screw or machine screw 22 is then threaded into the speed nut 16 until the rounded end approaches the bottom of the U-shaped conversion terminal 18.
Similarly, the auxiliary terminals 34 are slipped into the apertures 36 in the flange 30 by inserting the open pronged end of the U-shaped terminal through the slot until the tabs 38 clear the upper surface of the flange and the lances 38 abut the bottom of the flange. The shape of the tabs 38 prevent the auxiliary terminal from coming out of the aperture 36. As best seen in FIG. 6, the U-shaped auxiliary terminal presents two male blade members 42 for the quick connection of two female line connectors slip-on clamps.
The U-shaped triple conversion terminal 18 includes a knurled surface on the interior bottom surface as shown at 44 in FIG. 4. The primary line supply wire is brought into the terminal block assembly and clamped between the oval end of the screw 22 and the knurled surface 44. The knurled area acts as a friction grip against the wire surface with which it is in contact and prevents the line supply wire from slipping out when the wire is clamped against that surface by the oval end of the set screw 22. Each of the conversion terminals 18 are able to deliver the primary supply to up to three secondary lines through the secondary male blade terminals 46 on the conversion terminal 18. The secondary terminals 46 are adapted, as the auxiliary terminals 34, to receive female slip-on clamp connectors from secondary electrical distribution lines.
Although three primary conversion terminals have been illustrated in the preferred embodiment, it will be apparent that more or less than three terminals may be employed in the terminal block assembly of this invention as dictated by individual situation needs. It will be further apparent that the terminal block assembly of this invention can be quickly and simply assembled without the use of tools in that the speed nut 16 is simply and easily slipped into the top slot of the T- shaped tunnel or cavity and retained therein, aligned with the counterbored aperture by the internal configuration of the tunnel 14. The U-shaped conversion terminal is quickly and simply slipped into the lower portion of the tunnel l4 and retained in a predetermined position therein by the reduced diameter portion 24 of the interior surface of the tunnel thereby retaining the U-shaped conversion terminal in alignment with a threaded machine screw or set screw 22 which is threaded through the speed nut 16. The addition of auxiliary terminals 34 in the flanged portion of the terminal block assembly adds additional versatility to the terminal block assembly of this invention.
