Definitions

  • This invention relates to electrical connectors and a connector to which a cam member is attached.
  • it relates to connectors with cam members whose housings can be completely engaged by little force with the housing of a mating connector by manipulating the slide-type cam member.
  • 6-54255 for example, so that the housing can be completely engaged with the housing of a mating connector by sliding or moving the cam member from a first and open position, from which the cam member can be connected with the housing of the mating connector that is in a temporarily engaged position, to the closed position, whereby the cam member is moved into a position at which it completely engages with the housing of the mating connector.
  • the object of this invention is to provide a connector with a cam member that enables the worker to quickly and correctly verify that the slide-type cam member was moved to the completely closed or connected position and that the connection with the mating connector was properly made.
  • a connector assembly with a cam member of the present invention comprises connectors whose housings can be completely engaged by sliding a slide-type cam member attached to one of the housings from a first position to a closed position, wherein the cam member is provided with a resilient latch, which is positioned outside of the housing.
  • the latch member When the cam member has been moved to the closed position, the latch member has a first surface that extends in a direction nearly parallel to the direction in which the cam member slides and is resiliently deformable in a direction nearly perpendicular to the direction of sliding.
  • the housing is also provided with a latch section, which has a second surface that extends in a direction nearly parallel to the direction of sliding.
  • the resilient latch member is provided with a protrusion, and it bends and deforms in a direction nearly perpendicular to the resilient latch member as it engages against the latch section when the cam member is slid from the first position to the closed position; the latch section is provided with a hole or aperture that receives the protrusion when the cam member is moved to the closed position, thereby causing the resilient latch member to be restored to its original state.
  • the second surface of the latch section is provided at a position where it will produce an audible sound when it comes into contact with the first surface of the resilient latch member when it has been restored to its original state.
  • Figure 1 is an exploded perspective view showing an embodiment of a disassembled connector with cam member and a mating connector.
  • Figure 2 is a view similar to Figure 1 showing the assembled connectors and the connector with the cam member in a first position.

  • the sliding cam member 30 is attached to the housing 12 in such a way that the cam member can slide in the A and B directions shown in the drawings, i.e. between the first position shown in Figure 2 and the closed position as shown in Figure 3.
  • Latch member 40 which extends in the B direction from the upper end of the side wall section 33 and extends from a position above the upper wall section 31 in a direction nearly parallel to the upper wall section 31, is located on the cam member 30, as shown clearly in Figure 1, and forms a unit with the cam member 30.
  • Latch member 40 has a first surface 41 that faces upwards, a protrusion 42, which has a bevelled surface 42a formed on the edge of that first surface 41, and a protrusion 43 formed at the back of the first surface 41.
  • a plate-shaped latch section 50 that extends in a direction nearly parallel to the upper surface 12a of the housing 12 is located on the upper part of the housing 12 and forms a unit with the housing 12.
  • This latch section 50 is joined to the housing 12 on three of the four surrounding sides by the front wall 51, which extends upwards from the front edge of the housing 12; the back wall 52, which faces to front wall 51; and the joining wall 53, which joins the front wall 51 and the back wall 52.
  • a hole or aperture 54 is located in the central part of the latch section 50 and receives the protrusion 42 on the latch member 40 of the cam member 30.
  • a second surface 55 is located on the latch section 50. Second surface 55 comes into contact with the first surface 41 of the latch member 40 and makes an audible sound when the protrusion 42 of the latch member 40 and the aperture 54 are engaged as shown in Figure 5.
  • the cam member 30 that has moved into the closed position can be slid in the A direction to return it back to the first position by pushing the protrusion 43 of latch member 40 down thereby bending the latch member 40 downward and undoing the connection between the protrusion 41 of the latch member 40 and the aperture 54 of the latch section 50; and with that movement the two completely engaged connectors 10 and 20 can be disconnected.
  • connector 10A of this embodiment differs from the configuration of the latch member 40A of the cam member 30A, and the latch section 50A of the housing 12A.
  • the latch member 40A of the cam member 30A extends in the B direction from the upper edge of the side wall section

Abstract

Pour permettre à un ouvrier de vérifier rapidement et sûrement si un élément de came du type coulissant s'est déplacé vers une position fermée pour permettre à un logement d'un connecteur correspondant de venir dans une position d'engagement complet, un élément de verrouillage élastique (40), qui s'étend vers un logement (12) depuis une extrémité supérieure d'une section (33) de la paroi latérale d'un élément de came (30), se trouve sur l'élément de came (30). Une section de verrouillage (50), qui a une ouverture (54) pour recevoir une saillie (42) de l'élément de verrouillage (40), se trouve sur une partie supérieure du logement (12). A mesure que l'élément de came (30) se déplace d'une première position vers une position fermée, l'élément de verrouillage (40) est poussé vers le bas par l'effet de la saillie (42) se déplaçant suivant une seconde surface (55) de la section de verrouillage (50). Lorsque l'élément de came (30) arrive à la position fermée, la saillie (42) vient se loger dans l'ouverture (54) et, en conséquence de cela, l'élément de verrouillage reprend sa forme initiale, par l'effet de son élasticité. Lorsque cela se produit, une première surface (41) de l'élément de verrouillage (40) est amenée en contact avec la seconde surface (55) de la section de verrouillage (50), ce qui produit un bruit audible indiquant un engagement complet entre les connecteurs correspondants.
