Abstract:
L'invention concerne un connecteur blindé du type comprenant une embase (1) fixée à une plaque de circuit imprimé (CI) et une fiche (7) destinée à être accouplée mécaniquement et électriquement à l'embase (1). Un premier organe de blindage (2, 4) est prolongé par des languettes élastiques de verrouillage (22) munies de harpons (24). Le blindage (9a) de la fiche (7) comporte des orifices (90a) dans lesquels s'engagent ces harpons (24). Les languettes (22) frottent sur le blindage (9a) de la fiche (7) et établissent un contact galvanique entre les blindages (9a, 2-4) de la fiche (7) et de l'embase (1). Elles assurent un verrouillage de celle-ci dans l'embase (1). La première languette (22) comporte une pièce rapportée (3) en matériau isolant formant levier qui permet de déverrouiller la fiche (7) et l'embase (1), lorsque l'on exerce une force de poussée (F 1 ) sur la languette (3) et une force d'extraction (F 2 ) sur la fiche (7).
Abstract:
Le connecteur comprend une série de tiges de contact métallique (1) espacées et coudées, noyées dans une matière électriquement isolante (2) qui est elle-même entourée par un blindage métallique (3). La matière électriquement isolante (2) est surmoulée autour des tiges de contact (1), le blindage (3) est constitué par deux blocs métalliques (4a) superposés comportant sur leurs faces en contact des canaux coudés (5a, 5b, 5c) recevant les tiges de contact (1) entourées par la matière électriquement isolante (2), ces canaux étant conformés de telle sorte que le blindage (3) soit interrompu dans une partie rectiligne du coude formé par les canaux, cette interruption de blindage mettant en contact la matière isolante (2) entourant les tiges de contact, sans créer aucun espace vide dans les zones (7a, 7b) où le blindage est interrompu.
Abstract:
An electric connector (1) presenting an insulating casing (2) with at least one axial cavity (3); an electric terminal (4) retained inside the cavity (3) by primary retaining means (18); and a secondary retaining device (25) in turn presenting a first movable element (26) which snaps on to the casing (2) for ensuring correct engagement and preventing release of the terminal (4) by the primary retaining means (18); the secondary retaining device (25) also presenting a second movable element (44) interposed between the first movable element (26) and the terminal (4), and which, when subjected to thrust by the first movable element (26), cooperates with the terminal (4) for at least partially expelling it from the cavity (3) in the event the terminal (4) is not correctly engaged by the primary retaining means (18); the first movable element (26) presenting an elastically deformable portion (36) which is released from the second movable element (44) in the event the terminal (4) is correctly engaged by the primary retaining means (18).
Abstract:
A hydraulic drive system for a battery operated portable compression tool (10). The tool (10) has an electric motor (26). The drive system has a self-regulating variable displacement pump (24) with a rotatable conduit frame (44) having radial conduits (80), pistons (46) reciprocally located in the conduits (80), and a ring bearing (48) surrounding the conduit frame (44) in an eccentric adjustable location. Ends of the pistons (46) are located against the inside of the ring bearing (48). A valve plate (60) located against a front end of the rotatable conduit frame (44) to control entry and exit of fluid into and out of the conduit frame (44) as it is rotated.
Abstract:
The electronic components, provided with a series of contact pins, are picked up out of a feed unit (50) by a pickup-and-insertion head (20) which travels along the Y axis to above a table (12) on which is mounted the printed circuit board, and which can travel along the X axis. The series of contact pins are pushed into the corresponding holes in the board after a visual inspection of the position of the contact pins and holes has been carried out. This visual inspection is carried out by a camera (70) which is fixed-mounted between the feed unit and the table (12), and by a camera (80) which is mounted in the vicinity of the head (20) and which can travel with said head.
Abstract:
The invention relates to a plug connector in which the cables are led out at an angle and having secondary locking, comprising a plug part (1) on which there are disposed at least two opposite tongues (2a, 2b) disposed parallel to the plug axis (3) and having outwardly pointing catches (4a, 4b), and a socket part with correspondingly arranged slots to receive the tongues (2a, 2b) and for the engagement of the catches (4a, 4b) on correspondingly disposed shoulders. The tongues (2a, 2b) in the plug part (1) extend towards the back wall (5). The surfaces (6a, 6b) of the tongues (2a, 2b) oriented in each case towards the plug axis (3) are bevelled away from the plug axis (3) towards the back wall (5) The tongues (2a, 2b) are arranged to pivot on the plug housing over substantially half their length. The back wall (5) is formed with slots (7a, 7b) in the region of the bevelled side surfaces of the tongues (2a, 2b) in such manner that a U-shaped yoke (8), on insertion of its limbs (8a, 8b) into the slots, forces the tongues (2a, 2b) away from the plug axis (3) in this zone so that the opposite ends of the tongues (2a, 2b) are moved with the catches (4a, 4b) towards the plug axis (3).
Abstract:
This invention relates to a beam waveguide plug comprising: a plug casing (5) which has for each beam waveguide cable (2) a plug segment (6) and a clamping segment (7) for fixing the beam waveguide cable (2) to the plug (1). The clamping segment (7) has a socket (15) with a plurality of serrations (8) pressed by their edges into the beam waveguide sheathing and extending substantially transversely of the beam waveguide axis, and recesses (9) disposed between the serrations (8), to accommodate (15) the sheathing material displaced by the serrations.
