Definitions

  • pin-type conductors e.g., hermetically sealed electrical motors
  • wires connected to the motor be equipped with receptacle-type, electrical connectors in an insulated housing.
  • a standard form of motor having a series of pins projecting from the shell is adapted to be secured to an equal number of electrical conductors by means of terminals on the conductors.
  • FIGURE 9 is a perspective view of the block of FIG- URE 1.
  • the assembly may be considered as being comprised of two components, i.e., the block B and the connector T.
  • the block is of thermosetting plastic insulating material of suflicient strength to withstand shock. It consists of three cavities 10, 12 and 14, each adapted to receive a connect-or therein.
  • cavities are identical, only one will be described. They are formed by the base 16 of the block B, a side wall 18, a top wall 20, an inside wall 22, and an end wall 24 (FIGURES 1, 5 and 6).
  • An aperture 26 extends through the base 16 of the block at right angles to the passageway in the tubular cavity member 10.
  • a recessed portion 28 (FIGURE 6) is undercut at the junction of the aperture 26 and the cavity.
  • FIGURE 1 is a perspective view of a block with a plurality of connectors therein, the block being partially cut away to illustrate the connector;
  • FIGURE 2 is a perspective view of a connector embodying the principles of the invention as secured to a wire;
  • FIGURE 3 is a view similar to FIGURE 2 illustrating the opposite side of the connector
  • FIGURE 4 illustrates the connector of FIGURE 1 to 3 stamped out of sheet metal prior to forming
  • FIGURE 5 is a bottom View of the block with connectors therein;
  • FIGURE 6 is a view taken through plane 6 -6 of FIGURE 7;
  • FIGURE 7 is a view taken through plane 7-7 of FIGURE 6;
  • FIGURE 8 is a view taken through plane 88 of FIG- URE 7;
  • the cavities 10 and 12 are parallel to each other, with cavity 14 therebetween in staggered relationship. As shown in FIGURE 5, the apertures extending into the cavities are triangularly disposed.
  • the preferment is illustrated in conjunction with a trio of header pins 30 (FIGURE 6), which emanate from a cup-shaped memher or .shell 3-2 which forms part of the shell of a herrnetically-sealed motor.
  • the assembly may be secured to the outside of the shell (FIGURE 6) and/ or the inside of the shell (FIGURE 8).
  • a pair of walls 34, 36 extend from the base 16 of the block B at each edge, so that conductors C disposed in the cavities 10 and 12 are guided therein.
  • the connector T (FIGURES 2, 3 and 4) is comprised of a ferrule-forming portion 40 adapted to grasp the bare end of the conductor, and an insulation-securing portion 42 adapted to be formed around the insulation on the conductor.
  • the pin-receiving portion comprises a pair of U-shaped members 44 and 46 which are resilient and engage the pin therebet ween.
  • An aligning and retaining ring 48 is secured to the members 44 and 46 by root portions 50, 52. Ring 48 is adapted to fit over a header pin 30, and a pro-be 31 on the ring projects into the undercut portion 28 (FIG- URE 3) to retain the connector T in the cavity.
  • a post 54 (FIGURE 7) is molded in the end wall 24 of each of the cavities and projects a distance inwardly so that it tits between the U-shaped members 44, 46 of the connector T.
  • the connector T may be stamped out of sheet metal on a progressive die to from a stamping as shown in FIGURE 4.
  • the ferrule-forming portions 40 and insulation-securing portion 42 are stamped at one end of the terminal, and the ring 48 and U-shaped members 44, 46 comprise the other portion of the stamping.
  • the stamped connector is severed on score lines 56 and 58 (indicated by dotted lines in FIGURE 4) to form a tab 59.
  • the ring 48 is out along the score line 60 and bent downwardly to provide the probe 3 1 which fits into the recess 28 (FIGURE 6).
  • the members 44 and 46 are then folded inwardly to provide the U-shaped contour, and then are rolled upwardly so that they are parallel.
  • the rbight of each U-shaped contour is beveled, 64, 66, to match the front wall of the block.
  • the pin-engaging sides are slightly beveled, as at 68 and 70, to permit easy insertion of the pin.
  • a connector T is crimped onto each of the conductors.
  • the ring 48 is bent slightly downwardly, and one of the terminals (FIG- URE 2) is forced into the cavity 10 (FIGURE 1). In this position, the side wall of the cavity supports the outer arms of members 44, 46.
  • the ring 48 bears against the bottom wall of the cavity until it passes the undercut portion 28.
  • the ring 48 then springs downwardly so that the probe 31 engages the undercut portion and locks the terminal in the cavity.
  • the tab 59 engages the end Wall 24 to prevent upward movement of the connector.
  • Identical terminals are situated in cavities 12 and 14 in the same manner.
  • the block With the terminals in the cavities, the block may be snapped onto the header pins 30 (FIGURES 6 and 8). If the block is secured to the inside of the shell (FIG- URE 8), then the block will be tilted slightly to provide more secure engagement between the connector and the pins. In this position, each of the rings 48 guides the pins into alignment in the connectors. The posts 54 in the end wall 24 prevent the header pin 30 from deforming the b ight of the U-shaped members 44, 46 which would impair resiliency. Each of the connectors engages each pin with a secure fit; however, the block may be forced in a direction away from the header pin 30 to disengage the connectors from the pins. Also, the connector may be withdrawn from the cavity by inserting a thin blade against the probe 31 to force it above the bottom wall of the cavity. In this position, the connector may be withdrawn easily.
  • this invention provides a simplydesigned, insulating block which cooperates with a connector to engage a plurality of pins. Excellent electrical connection is maintained throughout the life of the assembly, and it is so designed as to preclude damage through misuse.
  • An electrical connector adapted to receive a pintype conductor, comprising: a pair of U-shaped members, disposed parallel to each other, each of said memhers having an inside leg and an outside leg connected by a bight, the inside legs of said members extending in the same direction and arranged to receive a pin in resilient frictional engagement, a ring-shaped member resiliently secured to said U-shaped members adjacent the bights thereof by root portions, the opening of the ring being in alignment with the pin-receiving axis of said inside legs, a probe means on one side of said ring-shaped member, and means for securing said U-shaped members to an electrical conductor.
