Definitions

  • the present invention relates to terminal blocks and more particularly to fastening means for securing terminal blocks to mounting strips or boards.
  • terminal blocks for effecting electrical connection.
  • These blocks each of which comprise an insulating body usually made of plastic material and provided with cavities or recesses for receiving the terminal posts, are stacked on mounting strips in order to occupy a minimal amount of space.
  • each individual block may be easily removed from the mounting strip without disturbing those lying adjacent thereto and accordingly, one of the objects of the invention is to solve this problem which has not up to the present time received any satisfactory solution.
  • the terminal block is provided, on one lateral side of its base, with a projection which engages under the flange member of a substantially C-shaped mounting strip and, on the other lateral side of its base, with a resilient metal glide (often associated with a ball or roller push-piece) slidably engageable under the other flange member of the strip so as to fasten the block thereon.
  • the present invention relates to a terminal block provided with fastening means which avoid these drawbacks.
  • the aforesaid metal glide is replaced by a simple projection of the insulating body which latter is made of a flexible plastic, said projection being formed with a slot allowing a resilient deformation upon mounting of the terminal block on a mounting strip or board.
  • the invention has also for an object to provide a new and improved terminal block which is easy to manufacture and at a low cost.
  • the invention is generally directed to a terminal block provided with fastening means for enabling it to be mounted in an apertured mounting board characterized in that said terminal block comprises an insulating body made of flexible material and is provided with a base beneath which are positioned offstanding lateral projections, a slotted kerf being formed between the projections to allow the latter to be engaged under the oppositely disposed flanged edge portion of the mounting board.
  • the lateral face of the projection is provided with a slot which is convex or cam-faced so that during the mounting operation the lips of the slot are drawn at first, closer and closer together, and then, after passing over the point of 3,430,190 Patented Feb. 25, 1969 maximum extent, thereupon separate and at which time the cam-faced projection is still in locking contact with the edge of the aperture.
  • the aforesaid slot extends along the greater part of the height of the projection and opens at the top thereof, said pro jection being thus only joined to the body of the terminal block by a narrow strip forming its base.
  • the body of the terminal block is provided with an abutment cooperating with the edge of the aperture and preventing the cam-faced projection, provided with the slot, from fully engaging under the edge of the aperture.
  • FIG. 1 is a side elevational view of a terminal block according to the invention
  • FIG. 2 is a side elevational view of a glide which protects one of the lateral projections of the terminal block of FIG. 1;
  • FIG. 3 is a partial end elevational view with the block turned and also showing the glide;
  • FIG. 4 is a side elevational view showing the terminal block tilted preparatory to its assembly with the mounting strip;
  • FIG. 5 is a side elevational view showing the terminal block fully assembled with the strip
  • FIG. 6 is a side elevational view of another embodiment incorporating the principles shown in FIG. 5;
  • FIG. 7 is a side elevational view of the alternative embodiment fully assembled with its strip member.
  • an insulating plate made of flexible plastic material and constituting the body of a terminal block is denoted at 10.
  • the details of the electrical connections have not been shown and need not be described since they do not form part of the invention and it is to be understood that the connections may be of any conventional type.
  • the body 10 is provided with right and left lateral projections 14 and 18 respectively.
  • the projection 18 forms a flexible arm extending substantially parallel to the side of the base of the body and is connected at its lower end by a narrow strip to a depending rib 18' and separated from the base of the body by a slightly flared slot 20 opening at the top of arm portion 18.
  • the lateral face of projection 18 is convex or camfaced, the apex of the convexity being shown at 24.
  • the projection 18 with a protection piece or glide 26, shown in FIG. 2.
  • This glide is preferably metallic and has one of its ends fitted in the slot 20 and its other end inserted in a recess or kerf means 28 provided in the base of body 10.
  • a groove 30 (FIG. 3) is formed in the base of the body 10 for receiving said glide.
  • the base of body 10 is narrower than the upper portion thereof so that a constriction 16 is formed between projections 14 and 18 and the upper portion to prevent the latter from passing through an aperture after the projections have been engaged therein.
  • the upper portion of body 10 also comprises an abutment 32 extending outwardly above the projection 18, said abutment thus preventing projection 18 from fully engaging under the edge of the aperture by cooperating gvith the edge as shown in the assembled position of FIG.
  • the fastening of the terminal block on a mounting strip is very easily executed (see FIG. 4).
  • the projection 14 is first engaged under the flange 34 of the mounting strip 12 and thereafter by pushing downwardly the glide 26 is caused to slide against the inturned edge or flanged extension 36 of strip 12 whereupon the projection 18 is retracted or forced backwardly until its apex 24 passes over the edge of extension 36.
  • the abutment 32 thus preventing the projection 18 from fully engaging under the horizontal inturned flange or extension 36.
  • This construction is particularly advantageous in that it facilitates the removal of block from the mounting strip 12.
  • FIGS. 6 and 7 relate to another embodiment of the invention which is particularly adapted in case the mounting strip is a C-shaped sectional iron or when the terminal block is intended to be mounted in an aperture provided in a mounting board.
  • FIG. 6 which may also utilize a C-shaped sectional iron member such as 12 or an apertured board 54, there is shown a terminal block 40 which is canted to the ight as viewed in the drawing preparatory to insertion in the board 54.
  • an angular projection 42 which defines thereabove a shoulder 44 and at the left side of its base it is provided with an integral oflstanding V-shaped flexible arm 46 connected to the body of the terminal block at the top of the inner leg of the V.
  • the outer leg of the V projects laterally and upwardly from the base of the terminal block 40, and the junction of the inner leg of the V is located below the base as shown.
  • This shape of the projecting arm 46 carried by the rib 48 is advantageous for particular types of installations since it provides even a greater flexibility.
  • the laterally extending face of the projecting arm 46 is convex, the apex of the convexity having been designated in the drawing at 50.
  • a downwardly projecting abutment means 52 analogous to abutment 32 of the terminal block of FIG. 1 is provided on block 40 and is of sufi'lcient length to prevent the projecting arm 46 from fully engaging under the edge of the aperture and preventing removal.
  • a thrust exerted along the line indicated 'by the arrow F6 after the projection 42 has engaged under the edge of the aperture causes the projecting arms 46 to retract until its apex 50 has passed over the opposite edge of the aperture thus engaging lip 52 with the upper surface of the board.
  • a thrust exerted as indicated in the direction of arrow F 7 results in a resilient deformation of the projecting arm 46 and in the subsequent disengagement of the projection 42 out of the aperture.
  • a terminal block assembly comprising, a channelshaped metallic mounting bar having opposed flanges, a terminal block having a base and upstanding side and end walls and a first integral rigid projection depending beneath one side wall, a bight portion between the side wall and said projection about which the terminal block is rotated into assembly with one flange of the mounting bar, said terminal block further including an integral horizontally disposed abutment merging with another side wall, and a second integral projection secured to said terminal body by a depending rib and having an upwardly extending flexible arm portion, said arm portion including a camming surface adapted to lock said arm portion in engagement with another flange of said mounting bar.
