Definitions

  • ABSTRACT This invention relates to an electric plug connection with a hermetically sealed housing having a housing base member and a housing cover member, each of the members containing one of a pair of mating electric plug connectors.
  • the invention encompasses a closure which, in a closed position elastically urges the two housing members together in a sealing relationship.
  • the closure is in the form of a plate pivotally mounted on a shaft in the base housing member and is rotatable thereon until the rounded end portion of the closure is elastically secured to a shaft in the cover housing member.
  • the closure has a gripping tongue which extends substantially ise'rpefidicuiafid the plane ofthe closure to provide ready access to the closure member for manipulation by an operator.
  • the closure may be adjustable in grip length or the distance between the shafts secured by the closure may be adjustable.
  • the closure cooperating with shafts disposed in the two housing members holds the shaft members against the biasing action of a resilient means in order to maintain the closure in a closed position and to maintain a hermetic seal between the two housing members.
  • This invention relates to an electric plug connection, and in particular plug connectors in which two mating plug members are brought to togetherer in a hermetically sealed relationship.
  • hermetically sealed connectors are of significant value for use in electrical installation and on electrically controlled machines where it is required to mechanically couple the pinsof a plug into the recess of a receptacle while further providing substantial mechanical integrity and protection against contamination in the environment.
  • tric plug connectors in which the members engageable by the closure are adjustable in position to accommodate manufacturing tolerances and wear of the closure and/or corresponding structure on the connectors engageable by the closure.
  • a closure movably supported on one of the housing members andengageable with a closure element mounted on the other of the housing members, the engagement between the closure and the closure element being secured by the biasing action of an elastic means.
  • closures could be operatively mounted for effecting a hermetic seal between two mating plug connectors and housing members or that a single closure could be used in conjunction with a hinge or other means of securing the portions of the housing opposite the closure.
  • a single closure is described, together with its associated parts on the housing members. It is to be understood, however, that two or more of the closures are contemplated to be uti- To simplify manual fastening of the closure, it is advantageous to provide the closure with a gripping tongue protruding outwardly from the housing members and extending substantially perpendicular to the same.
  • a particularly space-saving arrangement is realized if thepositioning and the mounting of the closure element is counter-sunk into the housing, in such a manner that in the closed position of the closure only the gripping tongue extends out of the housing surface. In this arrangement, the danger of damage to the critical portions of the closure and associated parts on the housing is avoided.
  • an elastic means is provided to maintain a sufficient and reliable hermetic seal between the housings.
  • the elastic means is in the form of an elastic sealing ring mounted between the joining housing members, thereby tending to force the housing members apart against the gripping action of the closure.
  • the elastic means may also exist in the closure itself, the closure being constructed from elastic material.
  • a seal may be provided for the two housing members for the purposes of sealing the same, by the tensioning forces to maintain a reliable seal is accomplished by the elasticity of the closure member tending to force the two housing members together.
  • the housing closure is rotatably mounted on a shaft in the base housing member, while an end portion of the closure embraces another shaft disposed in the cover housing member, the end portion of the closure being rounded in construction to embrace the shaft in the cover housingmember about a circumference of the shaft greater than and preferably about
  • the closure may be provided with means for adjusting the grip length of the closure.
  • Such an arrangement is implemented by providing the closure in two parts, the two parts .being slidable with respect to one another, yet maintainable in a fixed desired relative position, such that the grip length of the composite closure is set at a desired or predetermined amount.
  • One means of producing such a construction of the closure is to provide on the mutually contacting surfaces of the two parts, a plurality of grooves which interengage, the two parts being held together at a predetermined grip length by the provision of a tightening screw.
  • the housing closure may be profitably constructed from a single piece of material, such as sheet material, it may be advantageous to provide an adjusting means for effectively adjusting the grip length by providing a means for varying the distance between the shaft upon which the closure is mounted and the shaft embraced by the rounded portion of the closure.
  • closure member may, in an alternative embodiment, be rotatably mounted on a shaft in the housing cover member rather than in the base housing member.
  • direction of movement of the gripping tongue of the closure corresponds to the direction of movement of the housing cover upon opening and closing of the closure. In this manner, both operation of the closure and the motion to remove the housing cover member is easily accomplished by the operator.

  • the cable ends may be held in position by means of screw clamps and suit able seals.
  • the housing base member 2 Upon closure of the housing, the housing base member 2 engages in the housing cover member 1 until, as shown in FIG. 2, the base member comes into position in a step-like relationship with the housing cover member 1. a a
  • FIG. 1 shows a pair of closure elements 6 disposed on opposite side walls of the housing 1,2.
  • the closures are constructed from a basic sheet material such as sheet metal and shaped at one edge in the form of a cylindrical tube 13.
  • the radius of the tubular portion of the closure is chosen to be pivotally mountable on a shaft 7 which is fixedly anchored in recess 8 of the housing base member 2.
  • the housing cover member 1 is provided with corresponding recesses 9 in which a shaft 10 is supported.
  • the closure 6 rotates about shaft 7 until a rounded portion 11 of closure 6 mates with and engages shaft 10 which acts as a mating closing element for the closure 6.
  • the closure 6 has two extended portions, one of which is disposed in the area of shaft 10 and is provided with a curved rounded portion 11 which is formed to partially surround shaft 10 by an angle of more than and preferably about
  • the other extension of closure 6 is shown as a gripping tongue 12 which projects outwardly from the general plane of the closure 6, and when the closure is in a closed position, the gripping tongue 12 extends outwardly from the exterior of housing members 1 and 2.
