摘要:
The described embodiments relate generally to methods of assembly of electronic devices. In particular, a rotationally induced pressure is used to activate a securing mechanism positioned between a component and an enclosure. The component and the securing mechanism may be located in an inaccessible region of the enclosure such that traditional, direct, assembly processes may not be feasible. The securing mechanism may take the form of a layer of pressure sensitive adhesive or a fastener between the component and an interior surface of the enclosure.

Disclosed are a high-density fiber connector and an assembly method thereof. The connector, adapted for use with a fiber adapter, comprises a connector casing, a ferrule, a spring and a boot, wherein the connector casing has a cross width of 2.5 mm to 4.5 mm. The connector casing comprises a front casing and a rear casing, which lock up one another to form a cavity. The tail of the connector casing is connected with a boot. On the connector casing are sequentially arranged a guide block and an elastic arm from the front toward the back. A fixed end of the elastic arm is oriented toward the tail of the connector, while a free end faces an insert end of the connector and includes a retaining bump. The ferrule 2 is fastened with the ferrule tailstock 3 and penetrates through a through hole at the front of the connector casing. The spring is compressed between the ferrule tailstock and a thrust block formed by inner walls of the connector casing. The provided fiber connector has a significantly reduced cross width of between 2.5 mm and 4.5 mm at the engaging surface without, however, compromising the structural strength and utility functions, such that the fiber connector may be more densely installed.

The invention provides a bracket 1 for attaching an electrical cable 6 to a vehicle, the bracket comprising a vehicle attachment portion 11, 31 for attaching the bracket to a vehicle attachment surface of the vehicle, and a cable securing portion 13, 33 for securing the cable to the bracket 1, the cable securing portion 13, 33 comprising a cable abutment portion 4, 8 against the front surface of which the cable 6 can be secured by a cable-tie 7 forming a closed loop around the cable 6 and cable abutment portion 4, 8, and a non-planar rear surface which at least partially defines the path of the closed loop of the cable-tie 7 behind the cable abutment portion 4, 8, the path passing a first region on one side of the non-planar rear surface and a second region on the opposite side of the non-planar rear surface, wherein, in use, the non-planar rear surface directly supports the cable-tie 7 at a third region along the path of the closed loop, the third region being positioned, along the path, between the first and second regions. The invention also provides an aircraft fuel tank comprising a plurality of such brackets 1 and an electrical cable 6, secured to each of the brackets with a cable-tie 7.

A connector body includes upper and lower housings. The lower housing defines a locking structure, a cable channel and a retention channel adjacent the cable channel. The upper housing defines a complementary locking structure for interlocking the housings, and a retention projection for registering with the retention channel. The connector body may be assembled by moving the housings along a first direction into a mated position in which upper and lower housings register with one another but are not interlocked, and then moving the housings along a second direction transverse to the first direction until the locking structures interlock and the retention projection is in registration with the retention channel with the strength members pinched therebetween. A cable connector assembly includes a terminated fiber optic cable received in the connector body, with the ferrule retained between the housings and the strength members pinched between the retention projection and retention channel.

A method and system for installing rivets is disclosed. The method involves positioning a rivet through a structure to be joined. The method further involves positioning a first rivet gun on a first side of the rivet and positioning a second rivet gun on a second side of the rivet. The method also involves synchronizing firing of the first and second rivet guns, so as to cancel forces that otherwise would propagate into the structure during installation of the rivet.
