Definitions

  • This invention relates generally to electrical connectors and more particularly to electrical receptacle terminal assemblies.
  • a present technology electrical tab receptacle terminal connector with visually inspectable components is disclosed in copending United States patent application Serial No. 107,681, filed October 13, 1987, owned by the assignee of this application and is incorporated herein by reference.
  • the receptacle terminal connector described in application Serial No. 107,681 allows the receptacle terminal to be extracted from the connector without the use of special tools thus allowing for visual inspection of the receptacle terminal and the internals of the connector.
  • a tab receptacle terminal is inserted within a terminal connector cavity and locked in place by an internal projection in the connector cavity. If an excessive pulling force is applied to the wire connected to the tab receptacle terminal, the projecting locking tab or retaining shoulder inside the connector may be sheared off. This will then allow the receptacle terminal to be "pushed out" of the connector block when insertion of a male tab terminal is attempted. This shearing of the locking projection and resultant pushout of the terminal from the connector body is the major problem in terminal connectors of this type, hence the visually inspectable feature.
  • the present invention eliminates the pushout problem of present tab receptacle connectors by providing a locking projection or retainer in the interior walls of the connector on each side of the inserted tab receptacle terminal.
  • One of these projections is fixed, the other is part of a biased finger as in application Serial No. 107,681. This biased finger is biased toward the inserted tab receptacle terminal thus ensuring firm engagement of the tab receptacle terminal with both locking projections because the locking projections project into apertures in the opposite faces of the inserted tab receptacle terminal.
  • a tab receptacle terminal fully inserted into the connector according to the present invention is firmly held in place. Insertion of the blade of a male tab terminal within the receptacle will cause a certain amount of force to be exerted against the locking projections. However, in the present invention, this force is transmitted to both projections thus permitting twice the total force to be applied without danger of shearing off the projections. This total force capability prior to shearing of the locking projections is much greater than the force required for blade insertion. In addition, normal anticipated tugging on connected wires will not cause shearing. Therefore the pushout problem is eliminated by the additional locking projections.
  • the terminal assembly of this invention is shown in Figures 1 and 2 as comprising a hollow body 10 formed of a molded plastic material and configured with a plurality of cavities 12, illustrated as four in number, for a like number of tab receptacle terminals 16.
  • Each tab receptacle terminal cavity 12 has inwardly directed stop shoulders 14 at the forwardly terminating end of cavity 12.
  • the shoulders 14 prevent insertion of a tab receptacle terminal 16 further than the full insertion depth shown in Figure 6.
  • each shoulder 14 projects inward at right angles to the axis of terminal insertion.
  • the outer surface 13 of each shoulder 14 is sloped inward to guide the insertion of a male terminal into the corresponding cavity 12.
  • Each wall 28 includes a movable portion consisting of a finger member 22 which is integrally formed at only one end 17 with the body 10 so that it can deflect within the cavity 12 in directions toward and away from opposite shoulder 18.
  • finger 22 is cantilever supported from the sidewall 28 of cavity 12 and is separated therefrom at its sides by two parallel slits 29.
  • Each shoulder 18 is formed on a non-movable or stationary wall 26 within the body 10.
  • the tab receptacle terminal 16 has two opposing apertures 19 and 21 into which the shoulders 18 and 20 project when receptacle terminal 16 is fully inserted within cavity 12 as shown in Figure 6.
  • finger 22 is slightly biased inward toward the opposite wall 26 of cavity 12.
  • the finger 22 is deflected in a direction away from wall 26, as shown in Figure 5.
  • the engagement of forward end 23 with the inclined surface 27 on the inner side of shoulder 18 causes a similar deflection of receptacle terminal 16.
  • the forward portion of terminal 16 is deflected away from wall 26 until the shoulder 18 is aligned with aperture 19 in tab receptacle terminal 16.
  • tab receptacle terminal 16 is fully inserted with both shoulders 18 and 20 aligned with and projecting into the corresponding apertures 19 and 21 in terminal 16 and the forward end 23 of terminal 16 engaging shoulders 14. Terminal 16 is thus locked in place.
  • an applied force tending to cause terminal 16 to be withdrawn will result in no motion so long as finger 22 is not deflected away from engagement with tab receptacle terminal 16.
  • any applied withdrawal force is opposed by both projections 18 and 20 against the aperture walls in the upper and lower sides of tab receptacle terminal 16.
  • the tab receptacle terminals 16 can be individually removed.
  • the retaining shoulder 20 is deflected out of engagement with the aperture 21 in the tab receptacle terminal 16 by manually deflecting the finger 22 from its terminal retaining position shown in Figure 6 to its release position shown in Figure 5, and terminal 16 is manipulated to dislodge it from the shoulders 18 and 20.
  • Tab receptacle terminal 16 can then be withdrawn from body 10. This enables easy inspection of the body 10 and the tab receptacle terminals 16 housed within.
