Definitions

  • Another object of this invention is to provide an improved plug contactor of the type described above, which can be readily and easily changed to a semi-permanent, reusable type, or one which cannot be withdrawn from the plugboard either by push pressure on the nose of the plug contactor, or by pulling on the wire to which the plug contactor is attached, but can be easily withdrawn from the plugboard by manually, or with a suitable tool, depressing the spring elements by which the plug is retained in the plugboard while independently pushing on the plug.
  • Another object of this invention is to provide a plug contactor constructed of several basic parts, a simple alteration of which results in the plug contactor being either a manual or semi-permanent device, above described, as desired.
  • Another object of the present invention is to provide a positively-acting latch element which will not damage the plugboard or panel during its normal life when being inserted and withdrawn.
  • Still another object of this invention is that of providing a plug contactor which makes, between the wire to which it is attached and the plugboard contact, an electrical connection of low resistance, which is relatively invulnerable to the adverse effects of corrosive action, etc.
  • a further object is the provision of such a plug which is simple and economical in construction, and which may be easily assembled, but which is sufliciently rugged to withstand even careless use, and has a long useful life.
  • FIGURE 1 is a perspective view of a plug embodying the features of the present invention.
  • FIGURE 2 is a longitudinal sectional view of the plug of FIGURE 1, with the plug being shown in fully-inserted position in one of the openings of a plugboard;
  • FIGURE 3 is a longitudinal sectional view, generally similar to that of FIGURE 2, but showing the plug in partially-withdrawn position with respect to the plugboard;
  • FIGURE 4 is a fragmentary sectional view similar to that of FIGURE 2, but showing the plug fully withdrawn from the hole in the plugboard;
  • FIGURE 5 is a fragmentary transverse sectional view, taken along the lines 5-5 of FIGURE 2, and showing the latch detail;
  • FIGURE 6 is a fragmentary transverse sectional view, taken along the lines 66 of FIGURE 3, and showing the latch detail in depressed condition for releasing the lug;
  • p FIGURE 7 is a longitudinal sectional view, generally 3,134,633 Patented May 26, 1964 similar to that of FIGURE 2, but showing the plug locked into the plugboard by a rearward push on the nose of the plug; and
  • FIGURE 8 is a fragmentary sectional view of another form of plug embodying the features of the present invention.
  • the plug includes an outer sleeve 2, and the central portion 2a which is cylindrical and is adapted to be slidably received in one of the openings 4a of the plugboard 4, as shown in FIGURE 2.
  • the rear central portion of the sleeve 2 projects from a forwardly-directed face 4b of the plugboard, and is provided in the present embodiment with a circumferential ridge 2b which serves as a stop to limit the longitudinal movement of the plug in the plugboard.
  • the rearmost portion of the sleeve 2 which projects from a forwardlydirected face 4b of the plugboard 4 to a region of access, is provided with a wire barrel 20 adapted to receive a wire conductor, and to withstand a crimp or radial reduction in diameter onto the wire conductor, thus resulting in coldforging the wire barrel and the stranded wire conductor 6a into a substantially solid mass, thereby producing a good mechanical and electrical connection.
  • the wire barrel 2c is integrally joined to the central portion 2a by a cylindrical portion 2a.
  • an insulating shroud or jacket 8 of plastic or the like which also serves as a fingergrip to facilitate grasping of the rear end of the sleeve for inserting the plug into or withdrawing it from the plugboard.
  • the insulating jacket 8 extends a substantial distance rearwardly from the point of connection between the wire 6a and wire barrel 20 to support the wire 6, and increase the resistance of the connection to fatigue caused by bending of the wire.
  • a nose portion 2e Extending forwardly from the central portion 2a of the outer sleeve 2 is a nose portion 2e, the forward end of which is rounded to facilitate insertion into a plugboard.
  • the nose portion 2e is adapted for electrically conductive engagement with a spring contact 14 in the electrical device with which the plugboard is associated so as to form an electrical connection between the wire 6 and contact 14 and complete a selected circuit.
  • the nose portion 22 is joined to the sleeve by a tapered transition piece 2g.
  • nose member 10 which floats axially to the position shown in FIGURE 7.
  • the central section 10b of nose member 10 is cylindrical and the forward end 10a is generally conical or rounded as shown. Integral with the central section 10b, on its rearward end, is an enlarged head which tapers up to a ridge with a rearwardly disposed tapered surface 10d on its rear end, as can be seen in the drawings. This arrangement permits limited longitudinal movement of the nose member 10 relative to the nose portion 2e of the sleeve, and prevents accidental withdrawal of the nose member 10 from the sleeve itself.
  • a spring member 12 Disposed in the central portion 2a of the sleeve is a spring member 12 which contains the latch elements used to hold the plug in the plugboard.
  • the spring 12 has a bight section 12c, out of which protrude catches 12d which lock in behind the forward inner surface of ridge 2b so as to hold the spring in place relative to the sleeve.
  • the spring member is bifurcated with arms 12a which extend forwardly in the sleeve 2. These spring arms 12a are resilient, and near their forward ends, integrallyformed latch portions 12b project radially outwardly through slots 2f in the sleeve in position to be engaged behind a rearwardly-directed face 4c of the plugboard.
  • the slots 21 extend into the central portion 2a of the sleeve 2 sufficiently to permit longitudinal movement of the latch portions 1212 (particularly in the embodiment shown in FIGURE 8) so that the spring 2 can travel far enough to come into engagement with the rear surface 10d of nose member 10 when it is in its forward-most position.
  • the forward and rearward surfaces of the latch portions 12b are properly beveled or tapered so that, as the plug is moved for insertion into or withdrawn from the plugboard, these inclined faces will engage the front or rear face of the plugboard, as the case may be, and cause the latch portions 12b to be cammed into the opening 4a of the plugboard.
  • the inclined forward surfaces of the latch portions 12b engage the forwardly-directed face 4b of the plugboard (FIG- URE 4), and cam the latch members into the opening 4a in the plugboard against the resistance of the resilient spring arms 12a to permit the plug to be inserted into the plugboard.
  • the inner surfaces of the latch portions 12b are formed, as shown in FIGURE 5, so that the spring arms 12a will depress inwardly (FIGURE 6) to such an extent that the latch portions 12b are within the opening 4a in the plugboard, as is illustrated in FIGURE 3.
  • the latch portion 12b When the plug reaches its fully-inserted position, as shown in FIGURE 2, the latch portion 12b will spring back outwardly and engage behind the rearwardly-directed face 40 of the plugboard. With the plug in this position, a rearward pull on the jacket 8 will cam the rear tapered surfaces 12f against the front edges of hole 4a and result in the latch portions 12b entering into opening 4a, as shown in FIGURE 3. This will permit the plug to be withdrawn from the plugboard.
  • Internally-beveled surfaces 12c of the latch portions 12b extend inwardly toward the center, and at their tips bend in a transverse direction, as shown at 12g in FIGURES and 6, so as to allow enough surface at 120 for the rearwardly disposed tapered surfaces 10d of the nose member 10 to cam the latch portions 12b outwardly.
  • the bent tip sections 12g will then overlap in a scissor-like fashion when the latch portions are depressed, as shown specifically in FIG- URE 6.
  • a rearward movement on the nose member 10 relative to the sleeve 2 such as is produced by a rearward push on the front end 10a of the nose member 10, causes the rearwardly disposed tapered surface 10d on the nose member to engage the internally beveled surfaces 12c of the latch portions 12b and cam the latch portions 12b outwardly so that the latch portions are locked behind the rear face 40 of the plugboard.
  • the above-described plug can be easily adapted so as to be a semi-permanent plug, in that it cannot be pushed from or withdrawn from the plugboard without the aid of a tool or device to depress the latch portions 12b inwardly.
  • This is accomplished by shearing off catches 12d and rendering the spring free to float a limited amount inside the sleeve 2. Shearing off of the catches 12d will allow the sleeve to move a limited amount longitudinally; therefore, any push pressure on the nose member 10 will bind surface 10d of the nose member against surface 12c of the latch portion and, in turn, lock the plug into the plugboard, as described above.
  • any rearward pull exerted on the jacket 8 will cause the spring member 12 to move forward relative to the sleeve until its internally-beveled surfaces 120 engage the rearwardly-disposed tapered surfaces 10d of the nose member 10 so as to cam the latch portions 12b outwardly.
  • the sleeve is free to move a limited amount longitudinally, as shown by small arrows in FIGURE 8.
  • the plug shown in FIGURES 1 through 7 may be inserted into or withdrawn from the plugboard by movement of the sleeve; however, the plug may not be pushed from the plugboard by rear- Ward pressure on the nose member 10.
  • the plug, shown in FIGURE 8 is a variation of that shown in FIGURES 1 through 7, but this plug may neither be pushed from the plugboard by rearward pressure on the nose member 10, nor may it be pulled from the plugboard by a pull on the wire to which it is attached.
  • the plug as shown in FIGURES 1 through 8, is formed of only four basic parts: the sleeve 2, which can easily be stamped from flat conductive metal, such as brass, and rolled to the configuration shown; the spring member 12, which also can be made from a flat stamping; the nose member 10, which can easily be formed on a screw machine or the like; and the insulating plastic shroud or jacket 8, which is molded onto the assembled plug after the wire lead is crimped thereinto.
