Definitions

  • This invention generally relates to the art of electrical connectors and, particularly, to an anti-vibration electrical connector which has means for relieving stress in an anti-vibration arm thereof.
  • Electrical connectors are used in a variety of applications or environments wherein it is desirable or necessary to protect the connector components or the mating connection of the connector with a complementary connector from vibrations due to the mounting of the connector.
  • the applications can range from automobiles to refrigerators and countless other environments.
  • anti-vibration means can take a wide range of forms, from fastening means for rigidly fixing the connector to its support, to more versatile means such as snap-action mounting means.
  • a connector housing can be molded with an integral anti-vibration arm which is yieldable or sufficiently flexible to bias the connector against its mount and to take up any slack therebetween which might otherwise result in rattling of the connector in response to vibrations.
  • the anti-vibration arm could engage and yield against one side of a panel, for instance, in a panel-mounted connector, or the anti-vibration arm might yieldably engage an abutment surface on a complementary connector.
  • anti-vibration arms, flanges, or the like which are integral with a molded dielectric connector housing
  • the anti-vibration means are subject to stresses, particularly when cantilevered outwardly from a substantially rigidified housing wall.
  • Dielectric housings of most connectors are fabricated of plastic material, and the cantilevered anti-vibration arms, flanges or the like too often are subject to breakage when encountering undue stress.
  • This invention is directed to solving these problems by providing a new and improved electrical connector which includes stress relief means in its anti-vibration means.
  • An object, therefore, of the invention is to provide an electrical connector with anti-vibration means in which is incorporated stress relief means.
  • the electrical connector is adapted for mounting in an aperture in a panel or the like and includes an appropriate housing.
  • a yieldable or flexible anti-vibration arm projects from the housing for engaging the panel when the connector is mounted in the aperture to prevent vibration between the connector and the panel.
  • Recess means are provided in the anti-vibration arm at a location to relieve stress in the arm during yielding thereof.
  • the anti-vibration arm is cantilevered from a rigid wall of the housing, as where the wall is thickened or rigidified by a polarizing rib.
  • the recess means is formed in the antivibration arm either at or near the portion of the arm close to the polarized rib and may be in the form of a hole or rectangular portion either partially or completely through the arm.
  • the recess means in the specific embodiment comprises at least one through hole in the anti-vibration arm immediately adjacent the polarized rib.
  • the anti-vibration arm is generally L-shaped, with one leg of the L-shaped arm projecting toward the panel for engagement therewith and with the through hole being formed in the other leg of the L-shaped arm adjacent the housing.
  • an electrical connector generally designated 10
  • a housing 12 having passages therethrough (not shown) for receiving and positioning appropriate terminals.
  • the passages communicate with apertures 14 at the front end of the connector, the apertures being provided for receiving tubular portions of a complementary electrical connector (not shown) which has terminals for mating with the terminals of connector 10.
  • a latch ramp 16 is formed integrally with the top of housing 12 for snapping engagement with a snap latch of the complementary connector.
  • the entire connector housing 12 is integrally molded of dielectric material, such as plastic or the like.
  • Electrical connector 10 is designed as a panel-mounted connector for mounting in an aperture in a panel or the like.
  • the anti-vibration means including the stress relief means of the invention, can be used in a variety of applications where the connector is provided with an anti-vibration means, such as a cantilevered arm, a flange or the like.
  • a resilient latch finger 18 projects outwardly from opposite sides of the connector (only one latch finger 18 being visible in Fig. 1).
  • the latch finger has a ramp surface 20 for positioning through the aperture in the panel to bias the finger inwardly in the direction of arrow "A" until a shoulder 22 snaps behind the side of the panel opposite the insertion direction of the connector.
  • Anti-vibration means in the form of a generally L-shaped anti-vibration arm, generally designated 24, projects outwardly from each opposite side of connector housing 12 spaced longitudinally from shoulder 22 of latch finger 18.
  • the L-shaped arm includes one leg 26 projecting toward shoulder 22 and a panel sandwiched therebetween, and the other leg 28 of the L-shaped arm projects outwardly from a side wall 30 of housing 12 in a cantilevered fashion in contact with a polarized rib 32.
  • cantilevered anti-vibration arm 24 is shown with the distal end of leg 26 engaging a back side 34 of a panel 36.
  • Latch finger 18 and its shoulder 22 are not visible in Figure 2, because the figure is a section through anti-vibration arm 24, and the arm is offset relative to the latch finger as can be seen in Figure 1.
  • the spacing therebetween is such that the arm yields in the direction of arrow "B" from its static position (shown by dotted lines) and its stressed position (shown in full lines).
  • the stress without the stress relieving means 38 would be greatest at a point on leg 28 just above the polarized rib.
  • the invention contemplates providing stress relief means in anti-vibration arm 24 to minimize stresses causes by yielding or flexing of the arm and to reduce or eliminate breakage of the arm. More particularly, recess means in the form of a through hole 38 is provided in leg 28 of the L-shaped arm. In other words, the hole is provided in the leg of the arm which is subject to flexing or bending relative to rigidified wall 30 of the connector housing.
  • through hole 38 is located immediately adjacent polarizing rib 32.
  • the hole is in direct alignment with polarizing rib 32 and may be of substantially the same cross-sectional dimensions as that of the rib. This arrangement and dimensioning is easily fabricated during integral molding of the entire electrical connector housing by a core-thru at the location of the stress relief hole.
