A terminal block (1) with an elastic retracting fixation member, including an insulation base (10) having a cavity (13) and a cable insertion slot (14) communicating with the cavity (13), a cover member (20) covering the insulation base (10) and having a tool access hole (23), a conductive assembly (30) arranged in the cavity (13) and having a carrying member (32), and an elastic retracting fixation member (40) arranged corresponding to the tool access hole (23) and having an elastic element (41) and a fixation element (42), the elastic element (41) arranged between the fixation element (42) and the cover member (20), the fixation element (42) being operatively disengaged from the cover member (20) to attach to the carrying member (32) and retracting into the cover member (20) via a recovery force of the elastic element (41). Accordingly, it is able to prevent disengagement of the fixation member effectively.

A system and method for monitoring rotation of a nut or bolt. The system comprises an indicator for mounting to the nut or bolt and which is configured to rotate with the nut or bolt. The system further comprises a detector configured to detect a rotational position of the indicator, and a transmitter (242) configured to transmit data indicative of the detected rotational position of the indicator.The method comprises mounting an indicator to the nut or bolt such that the indicator rotates therewith, detecting, by a detector, a rotational position of the indicator - (442), and transmitting, by a transmitter, data indicative of the rotational position of the indicator.

A captive fastener attachable to a panel along a fastener axis is provided. The captive fastener includes a fastener having a head portion and a shaft extending from the head portion and along the fastener axis. The captive fastener also includes a knob having a proximal end portion engaged to the head portion of the fastener and an annular portion extending radially around the fastener axis and the shaft of the fastener. A ferrule is associated with the knob, the ferrule defining an opening extending along the fastener axis and receiving the shaft of the fastener. The ferrule has a proximal end portion configured to prevent separation of the knob from the ferrule along the fastener axis and a distal end portion configured for engagement to the panel. A spring is positioned to bias the knob or the fastener proximally relative to the ferrule and to inhibit tilting of the knob or the fastener relative to the fastener axis. The proximal end portion of the ferrule having been positioned to be associated with the knob in an insertion direction along the fastener axis, and the head portion of the fastener having been inserted within the knob for engagement to the knob in the insertion direction. The engagement between the proximal portion of the knob and the head portion of the fastener is configured to resist axial movement of the knob relative to the fastener along the fastener axis, rotational movement of the knob relative to the fastener about the fastener axis, and pivotal movement of the knob relative to the fastener axis.

An example device in accordance with an aspect of the present disclosure includes a grip to secure the device to an expansion card. The grip includes an upper grip portion to receive a fastener, and a standoff formed by a lower grip portion. The standoff is to establish a standoff distance between the expansion card and the mainboard when the device is secured to the expansion card and fastened to the mainboard.

A fence panel coupler 10 comprises a first clamping member 12, a second clamping member 14 and clamping means to connect the first clamping member 12 to the second clamping member 14. The clamping means is arranged to enable the first clamping member 12 to be moved towardsor away from the second clamping member 14 in order for the fence panel coupler 10 to be releasably clamped to a fencing structure. In particular, the fence panel coupler 10 is arranged to secure a fence post (or pole) 20 of a first fence panel to an adjacent second post (or pole) 22 of a second fence panel. The present invention provides a fence panel coupler which can be operated by a single person located on one side of the perimeter fencing. The fence panel coupler 10 comprises a first clamping member 12 which is permanently attached to the second clamping member 14 such that the two clamping members 12, 14 cannot be released from each other. The fence panel coupler is therefore a self contained element with no detachable components. The fence panel coupler 10 is preassembled and the first clamping member 12 is inseparable from the second clamping member 14.

A fastening system includes a fastener having a shank with a threaded portion and a head region disposed at an end of the shank and defining a retaining cavity in an end thereof. A clip includes a base region snap fit in the retaining cavity of the fastener and an anchor region for anchoring a wire harness, hose, cable sheath or other component.

A grooved rotatably fastening structure includes, in top-to-bottom sequence, a head, a shaft connected to the head, and a fastening portion connected to the shaft. The fastening portion has a first groove and a second groove. The first groove is concavely disposed on a lateral surface of the fastening portion and extends upward from a bottom of the fastening portion. The second groove is concavely disposed on the lateral surface of the fastening portion and extends from the first groove transversely or obliquely. The first groove and the second groove are in communication. The rotatably fastening structure enables users to connect two objects together quickly without compromising the structural strength of the two objects and is applicable to thin objects.

A retaining feature incorporated into a mounting surface of a plasticized article which is adapted to receive and retain a fastener prior to final assembly. The retaining feature exhibits an irregular and three dimensional shaped closed profile defined along an interior perimeter configured within the mounting surface and which establishes a degree of flex or bend upon insertion of the fastener with minimal loss of material. The insertion force can be any of lesser, equal to or greater than the extraction force, in combination with providing a rated side load breaking/shearing strength of the bolt from the material defined retaining feature.

A compression fitting is provided. The compression fitting may include a body, a follower, and a pin, and a cap nut. The follower may be disposed within an axial cavity of the body. The pin may be coupled with the follower. The cap nut may be coupled with the body. An internal edge of the cap nut radially overlaps at least a portion of a forward edge of the pin.

The invention relates to a lighting height corrector for a motor-vehicle headlamp with a reflector, comprising an adjustment element (9) capable of modifying the tilt of said reflector (3), a threaded rod (10), and a means for actuating the translation (7) of said threaded rod (10), said adjustment element (9) being translatably movable by being screwed or unscrewed on said threaded rod (10), said adjustment element (9) including for this purpose at least one thread (92) shaped such as to engage with the threading of said threaded rod (10), characterised in that the threading of said threaded rod (10) includes, at the distal end thereof, at least one abutment (104a) shaped to limit the translation of the adjustment element (9) away from the threaded rod (10), by engaging with said thread (92).
