Definitions

  • such a housing should be capable of accommodating terminals having somewhat difierent dimensions and that the tolerances permissible in molding the housing should not be uneconomically close.
  • an electrically insulating molded synthetic plastics housing for an electrical terminal for mating with an electrical tab comprises a first and a second pair of walls defining a tubular body which is open at both ends, a first stop extending inwardly of the housing from one end of one wall of the first pair of walls, and a detent extending inwardly from the other wall of the first pair of walls at a posi tion intermediate the ends of the housing, the stop and the detent cooperating to secure in the housing, the electrical terminal when inserted into the housing from the end of the housing opposite to that at which the stop is disposed, the housing being provided with additional stops at the same end of the housing as the first stop and which extend inwardly of the housing, the additional stops being disposed one on either side of the detent to prevent the tab from being inserted into the housing so as to lie between the terminal and the other wall of the first pair, a solid internal rib extending from the detent towards the end of the housing at which the stop is disposed, to engage in a reces
  • the terminal need not fit snugly in the housing.
  • the rib need not extend up to that end of the housing at which the stops are disposed, since it is unnecessary to use the rib for preventing the tab from being inserted into the housing so as to lie between the terminal and the other wall of the first pair.
  • FIG. 1 is an enlarged perspective view of a housing for an electrical terminal for mating with an electrical tab which is shown in fragmentary form;
  • FIG. 2 is a view of one end of the molded synthetic plastic housing for the terminal
  • FIG. 3 is a view of the other end of the housing of FIG. 2;
  • FIG. 4 is a longitudinal sectional view taken on the lines 4- 4 of FIG. 3;
  • FIG. '4A is a sectional view similar to FIG. 4 but showing a terminal in the housing;
  • FIG. 5 is a longitudinal sectional view taken on the lines 5- 5 of FIG. 3;
  • FIG. 6 is a similar view to that of FIG. 2, but showing the terminal in the housing.
  • the terminal which is generally,
  • the receptacle portion 2 has a base 7 from which extends the stub 7a of a metal slug by which the terminal 1 was joined to a further and similar terminal to form part of a strip of terminals. Sidewalls 8 extending from opposite sides of the base 7 are inwardly rolled so that their free ends 9 are directed towards the base 7. A tab 10 is mateable with the terminal 1. On mating, the tab enters the receptacle portion 2 between the base 7 and the free ends of the sidewalls 8.
  • the housing which is generally referenced 11, and which is preferably made of polypropylene, comprises a first pair of walls 12a, l2bjoined by a second pair of walls 13 to form a substantially rectangular section tubular body which is open at both ends.
  • the walls 12a, 12b and 13 are of equal thickness, the walls 12a and 12b being broader than the walls 13.
  • Interiorly of the body a solid rib 14 of wedge-shaped cross section extends longitudinally of the body substantially centrally of the wall 12a, the rib 14 extending away from one end 15 of the body and overlapping a wedge-shaped detent 16 which, as shown in FIG. 5, is spaced from the walls 13.
  • a first stop 18 formed as a rudimentary wall extends between the walls 13 at the end 15 of the housing and has in its edge, a recess 17 which is slightly wider than the stub 70 of the terminal ll
  • Two spaced-parallel ribs 19 extend from the stop 18 up to the other open end 20 of the body.
  • the wall 12a of the housing has two additional stops 21, one on each side of the rib 14, at the end 15 of the body.
  • the wall 12a also has a raised or stepped portion 22, so that the orientation of the housing can be determined by feel.
  • the terminal 1 is inserted into the housing 11, with the receptacle portion 2 leading; through the open end 20 of the housing and being guided by the ribs 14 and 19 until the leading end of the receptacle portion 2 engages the stops 18 and 21.
  • the crests of the sidewalls 8 engage the detent 16 so that the walls 12a and [2b are flexed outwardly of the housing 11.
  • the detent 16 is disengaged by the sidewalls 8 so that the walls 12a and 12b of the housing snap back into their original positions so that the terminal l is restrained from axial movement with respect to the housing 11 between the stops l8 and 21 and the detent 16, the stub 7a of the portion 2 of the terminal 1 engaging in the stop 18, as shown in FIG. 6.
  • An electrically insulating molded synthetic plastics housing for an electrical temlinal for mating with an electrical tab, the housing comprising a first and a second pair of walls defining a tubular body which is open at both ends, a first stop extending inwardly of the housing from one end of one wall of the first pair of walls, and a detent extending inwardly from the other wall of the first pair of walls at a position intermediate the ends of the housing, the stop and the detent cooperating to secure in the housing, the electrical terminal when inserted into the housing from the end of the housing opposite to that at which the stop is disposed, the housing being provided with additional stops at the same end of the housing as the first stop and which extend inwardly of the housing, the additional stops being disposed one on either side of the detent to prevent the tab from being inserted into the housing so as to lie between the terminal and the other wall of the first pair, a solid internal rib extending from the detent towards the end of the housing at which the stop is disposed to engage in a recess defined
  • An electrically insulating, molded synthetic plastics, elongate housing for an electrical tenninal for mating with an electrical tab the housing comprises a first pair of walls and a second pair of parallel walls defining a tubular body whichis open at both ends, the walls being of equal thickness and the walls of the first pair being of substantially greater width than the walls of the second pair, a first stop extending inwardly of the housing from one end of one wall of the first pair of walls and a wedge-shaped detent rigidly secured to the other wall of the first pair at a position intennediate the ends of the housing serted into the housing so as to lie between the terminal and the other wall of the first pair, a solid internal rib fonned integzally with the detent extending midway between the walls of the second pair from the detent towards the end of the housing at which the stops are disposed, to engage in a central recess defined by the terminal to ensure that the tem'linal can be inserted into the housing with only one orientation with respect to the
