Patent number: 4173385Abstract: An environmentally protected connector assembly for terminating a coaxial cable includes a tubular stem insertable between the braided outer conductor and inner insulation of the cable and fixedly carrying a collar and rotatably carrying a coupling nut for connection to a compatible connector component. O-rings provide seals between the coupling nut and the compatible connector and the collar. A resilient sleeve is received over the cable and includes inner ribs adjacent to one end to provide a watertight seal with the cable and having at the other end a lip engaging a flange on the collar to provide a further watertight seal. A retaining shoulder in the sleeve cooperates with an enlarged portion of the insertion end of the stem to retain the sleeve in place and provide further sealing. A crimp ferrule around the cable serves to clamp it on the connector stem.Type: GrantFiled: April 20, 1978Date of Patent: November 6, 1979Assignee: Bunker Ramo CorporationInventors: John W.

Patent number: 4169643Abstract: A mating clip is provided for use in securing together the mated halves, i.e., a mated receptacle and plug, of a connector. The mating clip is of one piece tubular construction formed from semi-rigid plastic and incorporates inner shoulders which fit grooves of a mated connector. The clip includes a longitudinal hinge integral to the body of the clip and opposite to a slit through the body. The hinge permits the body of the clip to be opened to receive a connector and closed to retain the connector. Latching means are provided in association with the slit to hold the mating clip in its closed state. The spacing of the inner ridges of the mating clip is such that the clip cannot be closed on a connector in place unless the connector is fully assembled so that its grooves mate with the inner shoulder in the clip. The clip prevents extreme flexure or bending of a supported connector.Type: GrantFiled: August 10, 1977Date of Patent: October 2, 1979Assignee: Bunker Ramo CorporationInventor: David A. Gallagher

Patent number: 4165910Abstract: An electrical connector is disclosed comprising complementary receptacle and plug connector members, each member having a hollow shell containing an insulating insert which houses electrical contacts. A rotatable coupling ring is carried by the plug and is engageable with the receptacle for mating the connector members and holding the contacts in electrical engagement. A resilient means is interposed between the coupling ring and the plug and has a predetermined range of axial deflection relative to the plug. The receptacle is provided with a plurality of bayonet pins and the coupling ring has a corresponding plurality of pin-receiving tracks to provide a bayonet type releasable connection between the coupling ring and the receptacle. The coupling ring has limited axial movement relative to the plug so that upon mating of the connector members, the coupling ring moves axially along the plug toward the receptacle compressing the resilient means therebetween.Type: GrantFiled: October 25, 1977Date of Patent: August 28, 1979Assignee: Bunker Ramo CorporationInventor: Norman R.

Patent number: 4160574Abstract: A connector for making intimate electrical contact with plural insulated conductors of a flat wire cable which includes plural contacts each having a pair of spaced-apart jaw members with insulation piercing and electrical contact portions extending substantially parallel to and on opposite sides of the axis of an associated conductor. Slots in an inner body portion of the connector hold the contacts in two laterally spaced rows on opposite sides of a central cavity. A rigid bar member inserted into the cavity forces the conductors into engagement with the contacts in both rows to first pierce and continuously strip the insulation adjacent a longitudinal portion of each conductor and then position the stripped conductor adjacent the contact portions which thereafter exert a force normal to and make broad flat surface contact with the conductors.Type: GrantFiled: November 29, 1977Date of Patent: July 10, 1979Assignee: Bunker Ramo CorporationInventor: Robert W.

Patent number: 4160139Abstract: A pressure sensitive switch for indicating when a fluid pressure reaches a predetermined limit includes a housing having a top wall and a dielectric substrate within the housing spaced from the top wall. A metal diaphragm is hermetically bonded to the substrate to form a cavity between the top wall and the diaphragm. The diaphragm includes a major resilient portion which deforms responsive to varying fluid pressures within the cavity. A first contact is fixedly mounted relative to the substrate and a second contact, arranged for movement with the deformable diaphragm, is spaced from the first contact in juxtaposition thereto. When the fluid pressure within the cavity reaches a predetermined limit, the second contact engages the first contact to close the switch. When the fluid pressure is below the predetermined limit, the second contact moves with the diaphragm away from the first contact to open the switch.Type: GrantFiled: August 29, 1977Date of Patent: July 3, 1979Assignee: Bunker Ramo CorporationInventor: Samuel A. Johnston

Patent number: 4159156Abstract: An insulated conductor is terminated in an insulation-opening portion of an electrical contact and the contact jaws are crimped over the conductor to secure the conductor therein. A tool includes a pair of cutting edges and crimping surfaces for cutting and folding over sections of the contact jaws as the tool presses an insulated conductor into an insulation-opening notch formed by the contact jaws. The tool includes a forward end having a surface for engaging and pressing the conductor into the notch, the surface acting against the conductor as a stop to limit the depth of cut of the cutting edges. The tool may also be used after conductor insertion by other techniques to perform the crimping operation. The side surfaces of the tool slidingly engage the cut edges of the contact jaws and prevent an inward movement of the jaws during cutting and crimping.Type: GrantFiled: February 7, 1978Date of Patent: June 26, 1979Assignee: Bunker Ramo CorporationInventor: John P.

Patent number: 4156965Abstract: Apparatus is shown for use in loading contacts in contact receiving bores of a resilient insert body. The insert body is provided with internal shoulders and bores forming restrictive passages for holding the contacts and for holding wires attached to the contacts. The apparatus includes an adapter associated with a breech loading assembly for accepting and holding the insert body. An assembly including a bullet within a barrel is pushed into the insert body to gently enlarge the shoulders and the bores. The bullet is then retracted to a stop position, leaving the barrel in place in the bore. The breech lock is then opened and contacts are loaded by hand, or other means, into the bore to the stop position. The barrel is then retracted from the bore permitting the internal shoulders of the resilient insert body to expand and grip the contacts. Thereafter, the resilient insert body, with its contacts and appropriate leads in place, is removed from the apparatus.Type: GrantFiled: January 12, 1978Date of Patent: June 5, 1979Assignee: Bunker Ramo CorporationInventors: Bruno C.
