Abstract:
A single-piece optical fibre coupling (1) is specified which has a housing (2) with at least two holder openings (3a, 3b), which are arranged coaxially and run towards each other, for the optical fibre ends (4a, 4b) to be connected, the holder openings (3a, 3b) each having an outer section (3c, 3d) with a threaded crimp (3g) and an inner section (3e, 3f) with a thread (3h) of lower depth.
Abstract:
The method consists in aligning a printed-circuit board 2 with respect to an insertion die 4 containing grooves 8, and an anvil 3 containing grooves 6 of a manually operated press, in order for at least one electronic component 1, which is provided with projecting contact pins 7 with elastic attachment zones, to be inserted into a selected insertion zone in the PCB 2, the insertion die 4 and the anvil 3 always being aligned with respect to one another along an insertion centre line c, and the printed-circuit board being attached to a manually displaceable X-Y table. the position of the centre point p of the selected insertion zone being respectively defined by means of a Y-coordinate and an X-coordinate with respect to the insertion centre line c, the table being moveable within a first tracking zone, the area of which extends over a great distance with respect to the insertion centre line c, and within a second tracking zone, the area of which extends over a limited distance with respect to the insertion centre line c.
Abstract:
Electrical connector provided with a casing having a front face and a rear face and having at least one row of cavities, accommodating female contact terminals, provided with first holes (30) emerging in the front face of the casing, and at least one of the walls of which has at least one elongate thin region forming a column (34) separated form the rest of the wall by slots parallel to the direction of insertion of the contact terminals into the cavities, this thin region being provided with an internal lug (36) to be engaged in a window in the terminals, the connector being furthermore provided with secondary locking means for the contact terminals, these secondary locking means consisting of studs (41) that can be moved perpendicular to the direction of insertion of the terminals between a parted position of the columns and a bearing position of the columns.
Abstract:
A hydraulically powered tool (10) having a motor (14), a pump (18), and a hydraulic directional flow control valve (20). The valve (20) has a frame (12) and a rotatable spool with flow channels. The valve is provided as a four position, six way valve to provide four operational conditions for the tool including NEUTRAL, DRILL, RETRACT and FAST FORWARD.
Abstract:
A card edge connector having a housing 10, first contacts 18a, and second contacts 18b. The first and second contacts each have mounting sections 28, 34 and cantilevered flexible sections 32, 38. The mounting sections of the first and second contacts have different lengths. The cantilevered flexible sections of the first and second contacts have the same length and shape. The first and second contacts 18a, 18b are inserted into the housing 10 at the same time on a single carry strip 26 to form multilevel contact areas 44, 48.
Abstract:
An electric connector (1) for connecting cables (2, 3), and which includes a connecting element (4) made of conductive sheet metal and connectable electrically to the cables (2, 3); and an enclosure (36) defined by an insulating covering (5) applied to an outer surface of the connecting element (4), and by a shielding cover (30) applied to the insulating covering (5).
Abstract:
The connector (1) consists of a printed-circuit board (4) connected to the conductors of the cable (2). The connector (1) carries a generally U-shaped spring (5), the arms (5a) of which have, at their ends, means (6) which engage with complementary means (7) in order to lock the connector (1) to a socket (18). The connector (1) has a pivoting lever carrying a member (10) which engages with the base (5b) of the generally U-shaped spring (5), this member being able to move, when the lever pivots, between a position in which this member is inactive with respect to the base (5b) of the spring (5) and the arms (5a) of the spring (5) are locked to the socket (8) and a position in which this member (10) exerts a force on the base (5b) of the spring (5) in order to unlock the arms (5a) of the latter from the socket (8).
Abstract:
An electric connector (1) presenting an insulating casing (2) with a number of axial cavities (3); a number of electric terminals (4) housed in the cavities (3); primary retaining means (18) for retaining the terminals (4) inside the cavities (3); secondary retaining means (25) in turn presenting a first movable element (26) connectable in a closed position to the casing (2); and a second element (33) interposed between the first element (26) and the casing (2) and movable between a disabling position preventing connection of the connector (1) to a complementary connector (1'), and an enabling position permitting such connection; the first element (26) presenting a pair of cam tabs (31) cooperating with the second element (33) so as to move it into the enabling position when the first element (26) is in the closed position.
