Abstract: An avionic system for an aircraft including at least two pieces of equipment which can exchange information by means of at least one electrical bus for simultaneous bidirectional communication, in which the information can be exchanged between pieces of equipment via an optical bus that can be connected to the electrical interfaces of the equipment. The optical bus of the avionic system includes at least one optical cable having at least one optical fiber and, at each end, a connector having means for converting electrical signals into optical signals and means for converting optical signals into electrical signals. The optical bus is connected to the electrical outlets of existing equipment.

Abstract: An avionic system for an aircraft including at least two pieces of equipment (10a, 10b) which can exchange information by means of at least one electrical bus for simultaneous bidirectional communication, in which the information can be exchanged between pieces of equipment (10a, 10b) via an optical bus (20) that can be connected to the electrical interfaces (11a, 11b) of the equipment. The optical bus (20) of the avionic system includes at least one optical cable (21) having at least one optical fibre (22) and, at each end, a connector (30) having means (41, 42, 45, 46) for converting electrical signals into optical signals and means for converting optical signals into electrical signals. The optical bus (20) is connected to the electrical outlets of existing equipment.

Abstract: The invention divulges a method of installing a nut in a cage in order to make a secure connection of two elements by screwing the nut on a threaded rod, particularly in the case in which the electrical connection is made using a lug. The cage is in the form of a cylinder comprising elastic inner strips that enable blocking of the washer and the nut, and ensure a constant pressure with time.

Abstract: An anti-loosening device for locking the head of a locking screw or nut, in particular for connection of an electrical terminal to a contact lug, wherein the device essentially comprises a plate having at least one catch element rotationally stationary in relation to the contact lug when the locking means are being fastened, and comprising a toothed element interlocking at the end of the screwing process with the catch element to resist unscrewing of the locking screw or nut.

Abstract: A connector composed of two hinged subassemblies (26, 28) that enable a removable rear connector to be fitted onto a plug (10) whether or not fitted with its wiring. Subassembly (26) comprises a collar formed of at least two sections (36a, 36b) capable of being placed behind the plug (10). Subassembly (28) forms a ring formed of at least two sections (56a, 56b) designed simultaneously to encircle the rear of the plug (10) and the collar. The ring operates in conjunction with the connector by means of threads (20, 60) and with the collar by means of a assembly consisting of a throat (62) and a ring-shaped ridge (54). The subassembly (26) is also prevented from rotating relative to plug (10).

Abstract: To permit the connection of an electric cable (12) in an end element (10) having a partly frustum-shaped outer surface, a crimping tool is proposed incorporating a gripping plier (50) and a crimping die (60). When the element (10) to be crimped has Been placed in a recess (48), an actuation of the tool has the effect of the element (10) being gripped by the plier (50), the closure of the die (60) and then the application of a tension to the end element by said plier (50), so as to make the die pass through said element. The die (60) then opens automatically and remains open until the tool has returned to the inoperative position.

Abstract: The invention relates to a method of tightly electrically connecting an electric cable (12) to an end member (10) such as an electric contact, it is proposed that the partly bared or stripped end of the cable be introduced into a stepped blind hole (26) formed in a rear connection part (10b) of the member (10). More specifically, the bared cable end is received in two cylindrical sections (26a,26b) of the hole (26), in which have been inserted beforehand a transparent sleeve (30), capping an inspection hole (32), and a metal interface ring (34). The unbared part of the cable is received in a cylindrical entrance section (26c) of the hole (26). Then, by wiredrawing, the partly truncated cone-shaped, outer surface of the part (10b) is deformed in order to give it a cylindrical shape.

Abstract: In order to connect an electric cable (12) having a light metal core (14) to a standardized end element such as a connector contact, the partly bare end of the cable is introduced into a blind hole (20) formed in a connecting part (10) made from an electrically conductive, cold deformable material. More specifically, the bare cable end is introduced into a truncated cone-shaped, intermediate portion (24) and into a bottom portion (22) of the hole (20), whilst the adjacent end of the cable sleeve (16) is introduced into a larger diameter, inlet portion (26) of the hole. In view of the fact that the part (10) has a truncated cone-shaped, outer surface around the blind hole, a radial compacting of the part has the effect of embedding the cable end in said part and mechanically joining the latter both to the core and to the sleeve of the cable.
