  • Patent number: 4913665
    Abstract: In a multi-pole plug connector assembly including pin and socket housings having contact carrying inserts connected therewith, the fastening screws used to connect the inserts with the respective housings have three different head configurations to serve as coding elements for indicating proper orientation of the housings for plugging connection therebetween. One of the three different head configurations can be combined only with itself while the remaining two head configurations can be combined only with each other. A large number of coding possibilities can be obtained for a plurality of adjacent connector assemblies without increasing the space requirement of the assembly and without decreasing the number of poles or pins being connected.

  • Patent number: 4825735
    Abstract: A pliers-type tool with two handles has a parallel mechanism carrying two carrier members for working jaws. The mechanism comprises two cross-wise arranged guide lever means and one of the carrier members or one of the guide lever means is merged with one of the handles to a rigid tool body. A resilient member may be interposed, also in tools not having a parallel mechanism, between a link connecting the two handles and a counter-element in order to compensate for inaccuracies and/or to enable an extra push at the end of a closing movement of the handles.

  • Patent number: 4726266
    Abstract: In a pair of pliers where at least one of two shanks which carry jaws is built up of two spaced side-plates, is in at least one of the shanks a tapered section arranged rearwardly of a pivot point where the shank is attached to the other one. By the rearward location, which also allows a less steep taper, the tapered section is more spaced from the pivot point, whereby the danger of rupture upon heavy loading is diminished. Also the handles may be built up of spaced side-plates between which a stem portion of a protective grip with T-shaped cross-section is inserted.

  • Patent number: 4685887
    Abstract: An electrical double plug and socket connector includes a socket component, a plug component and a short-circuit bridge. Each of the socket and plug components includes an insulating material housing. Metallic contacts are arranged in the socket component housing, and associated metallic connecting elements are arranged in the plug component housing. The plug component housing bounds a receiving space located between the connecting elements. The short-circuit bridge includes a U-shaped spring accommodated in the receiving space but having two arms which project axially out of the receiving space toward associated insulating material lugs of the socket component housing to such an extent that the connecting elements project beyond the arms by more than the distance by which the lugs extend beyond the contacts.

  • Patent number: 4637242
    Abstract: A locator device for a tool with crimping dies for cable shoes has at least one track for accommodating the contact portion of the cable shoe, a stationary stop at the end of the track and a movable stop at a selected location along the track. For treating cable shoes with longer contact portions, the movable stop is lifted from the track so that the stationary stop is operative, and when treating cable shoes with shorter contact portions the movable stop is put in place. The device is preferably made as a readily mountable accessory to the crimping tool.

  • Patent number: 4630462
    Abstract: A tool for crimping cable shoe terminals having an affixing part and a contact part onto the ends of electrical conductors has a pair of jaws provided with at least one pair of co-operating crimping dies and hinged together by a pivot pin. On the same pivot pin is mounted a rocker arm carrying for each pair of crimping dies a chamber accommodating the contact part of a terminal to be crimped. The rocker arm is affected by a position-controlling force such as friction at the location of mounting, and by suitably located dog means so that it makes a move, after the crimping operation has been terminated, by which the terminal, now crimped on a conductor, is lifted from the crimping die so that it readily can be removed from the tool.

  • Patent number: 4627314
    Abstract: The stripping device comprises a pair of jaws of which each is provided with a cutting knife. For secure positioning of an inserted conductor, and in order to strip off a severed portion of its insulation layer, a resilient positioning element with a tapering recess is provided adjacent one cutting knife. The positioning element grasps and guides the conductor already when the cutting edge of the cutting knife begins to penetrate into the insulation layer, and yields thereupon resiliently without releasing the conductor. Said cutting edge is preferably provided with a semicircular recess which may be produced by a plurality of blanks fixed in a sloping position being worked by a metal removing tool having at the periphery the profile shape of said recess.

  • Patent number: 4616533
    Abstract: A stripping device for coaxial cables comprises a handle member and a guiding track member for a predetermined end length of a cable, rotarily mounted in the handle member. Knife means, mounted in a knife holder which is pivotally attached to the guiding track member, are provided to perform at least two spaced incisions in the cable. A locking means connects temporarily an inserted cable non-rotarily with the handle member. By pivoting the knife holder towards the guiding track member and at the same time rotating the guiding track member with the attached knife holder about the cable locked in the handle member, a first incision is made and extended along the whole periphery of the cable by the knife means which is closest to the end of the knife holder remotest from the handle member.
