Definitions

  • the present invention relates to an hermaphrodite electrical contact.
  • Such contacts have particularly advantageous application in many fields, for example, for electrically coupling vehicles to each other.
  • hermaphrodite contacts it is no longer necessary to consider the orientation of the contact when the vehicles are coupled together.
  • hermaphrodite electric contact in which the contact-making parts are made of a fiat metal piece which has an elongated indentation in its middle with two hooks directed toward the middle of the indentation.
  • These known hermaphrodite contacts are coupled together by rotating one contact by 90 and inserting it into the other contact.
  • the object of the present invention to provide an hermaphrodite electrical contact in which the contact-making parts slide resiliently over each other throughout a relatively long path.
  • each flat leaf spring has its end longitudinally slit, and each flat spring comprises two individual springs positioned one above the other.
  • FIGURE 1 is a perspective view of one hermaphrodite electrical contact of this invention.
  • FIGURE 2 is a vertical cross-sectional view of two hermaphrodite electrical contacts of FIGURE 1.
  • FIGURE 3 is a front view of another hermaphrodite electrical contact of this invention.
  • FIGURE 4 is a side view of another embodiment of a contact arrangement according to the present invention, the same including two contact-making leaf springs in contact with each other.
  • a conductor 1 is secured to an elongated housing 3 by means of a set screw 2 threaded into a sleeve 11 which surrounds a reduced portion 3a of the housing 3 so as to be electrically conductively connected with the housing 3.
  • a recess 4 At the front end of elongated housing 3, there is a recess 4 in which two flat contact-making springs 5 are punched out, the ends of these flat springs being angled so as to extend in the longitudinal direction of the housing.
  • the two flat springs slide against each other when the two contacts are slipped one into the other, for example when railway cars are being coupled, and assume the position shown in phantom lines in FIGURE 2, It will be seen that even if the mutual distance between the two contacts is changed, as can often happen in operation, the two contacts will still be in continuous engagement with each other.
  • a sleeve 6 not shown in FIGURE 1 but illustrated in FIGURE 2 is slidably arranged in the front part of housing 3. In rest condition, this sleeve projects beyond the edge of the housing. In operating condition, the sleeve is pushed into the interior of the housing against the action of a compression spring 7, this spring being interposed between a solid head 6a of sleeve 6 and an abutment 12. As shown in FIGURE 2, the head 6a of sleeve 6 is provided with grooves 6b into which project tabs 3b bent inwardly from housing 3.
  • each fiat spring 5 has their ends slitted longitudinally so as to make better contact, while in the embodiment of FIGURE 4, each fiat spring 5 consists of two individual springs 8 and 9 arranged one above the other.
  • the contact-making spring 9 is adidtionally provided with a projection 10 extending toward the contact side which serves as a detent point.
  • hermaphrodite contact can be used not only with a similar contact, but with a differently configured contact element. All that is necessary is that the contact element be capable of being introduced into the cross section of the sleeve 6. For example, a simple plug-type contact of appropriate dimensions can constitute the suitable cooperating contact element.
  • the contact according to the present invention is suitable for use not only in conjunction with vehicle couplings and especially railroad car couplings, but can always be used to advantage whenever a reliable resilient contact is to be made over a relatively long path.
  • An hermaphrodite electrical contact comprising, in combination (a) an elongated housing; and
  • first and second contact-making springs each extending out of said elongated housing and diagonally into the interior thereof, said two flat springs being positioned on opposite sides of said housing and being inclined toward each other, said two flat springs being crossed within said housing.
  • each of said flat springs has its end longitudinally slit.
  • An hermaphrodite electrical contact comprising, in combination:
  • first and second contact-making springs each extending out of said elongated housing and diagonally into the interior thereof, each of said flat springs comprising two individual springs positioned one above the other.
