A connector assembly is provided. The connector assembly includes a connector body, a movable component selectively movable between an uninstalled state and an installed state, a digital tag, and a digital blocker. When the movable component is moved from the uninstalled state to the installed state, the digital blocker is moved relative to the digital tag from a position where the digital tag is blocked by the digital blocker to a position where the digital tag is unblocked by the digital blocker, thereby providing a digital indication of a successful connection between the connector body and the movable component.

A fixing system for a rocker arm of a vehicle suspension has a threaded rod having a first thread, a second thread and a locking cavity. The fixing system has a first cam, integral for rotation with the threaded rod by shape-fitting coupling, a second cam integral for rotation with the threaded rod by shape-fitting coupling, a first nut, screwed onto the first thread to lock position of the first cam, and a second nut, screwed onto the second thread to lock position of the second cam and having a locking portion having a circumferential groove and a positioning hole passing through the circumferential groove. An elastic clip shaped as an open ring is accommodated in the circumferential groove for retaining a pin in the positioning hole. In a screwed position of the second nut, the pin fits into the locking cavity and locks the position of the second nut.

A fastening device includes a male member having a head portion at a proximal end along a first central axis, an impact retention stem protruding from the head portion along the first central axis towards a distal end, and a tooth portion. A female member, having a first cavity, extends along a second central axis to guidingly receive the impact retention stem, a periphery of the female member having a lip portion extending towards the second central axis and adapted to lockably engage with the tooth portion, and a second cavity, extending perpendicular to and intersecting the second central axis. A locking member is configured to be guidingly received by the second cavity and is adapted to retainingly receive the impact retention stem and provide a biasing force along the first central axis towards the head portion in cooperation with the tooth portion when operably engaged with the lip portion.

A fitting includes a screw portion that is rotatable around an axis extending in one direction, an operating portion that applies a torque around the axis to the screw portion, and a rotation auxiliary member that is configured to be engageable with the operating portion. A slot extending from a first end to a second end is provided in the rotation auxiliary member, and also a first projection that protrudes outward is provided on the rotation auxiliary member. A positional relationship of the first projection is set such that an engaging force between the rotation auxiliary member and the operating portion is increased due to a change in width of the slot in a case where a force is applied to the first projection in the first rotation direction with the rotation auxiliary member engaging with the operating portion.

A ratchet fitting includes a screw portion and an operating portion. One of the screw portion and the operating portion has an engaging member, and the other one of the screw portion and the operating portion has an elastic member and a holding member formed separately from the elastic member. The elastic member and the engaging member are fitted such that a rotational force is transmittable to each other due to engagement of the projection and the protrusion and engagement between the projection and the protrusion is releasable due to deformation of the elastic member. The elastic member has a first fitting portion, the holding member has a second fitting portion, and the holding member and the elastic member are fitted such that the first fitting portion and the second fitting portion are fitted to each other in a rotation direction.

A connector includes a connector body having a hollow channel, and a retainer configured to prevent a pipe inserted into the hollow channel from being removed using a stopper piece. The retainer body lies along the outer peripheral surface of the retainer attachment portion. A bearing allows the retainer body to rotate from a temporary locking position to a main locking position. A detection piece passes through a detection hole and projects into the hollow channel when located in the temporary locked position, so as to be pushed in an axial direction by a bulge of the pipe. An inclined surface of the detection piece inclines with respect to the axial direction such that a pushing force can be converted to a radially outward force. A first energy conversion mechanism serves to convert the energy converted by the inclined surface to the rotational energy in the locking direction.

In one embodiment, a fastener includes a flexible head and a shank coupled to the flexible head. The flexible head includes a center head portion and a plurality of wing portions coupled to the center head portion. Each of the plurality of wing portions includes a contact area configured to contact a first surface of a part to be fastened. The shank includes a clip groove configured to hold a retainer clip against a second surface of the part to be fastened. The second first surface of the part to be fastened is opposite the first surface of the part to be fastened.

A retention ring is configured to retain components within a transmission assembly. The retention ring has an annular main body defining an opening through a center thereof. The annular main body defines an outer curved surface and an inner curved surface, the annular main body having a distal face disposed in a distal plane and a proximal face disposed in a proximal plane. A first set of retention features extend from the inner curved surface, and a second set of retention features from the outer curved surface. One of the sets of retention features is configured to engage a backing plate or an outer member, and at least one of the sets of retention features is entirely disposed between the proximal plane and the distal plane. A transmission assembly includes the retention ring and an adjacent external snap ring.

An arrangement for a shifting brake device. The arrangement includes a housing, a reaction plate and a snap ring. The housing and the reaction plate are mechanically connected to each other and the snap ring is arranged in a groove of the housing for locking the reaction plate to the housing such that displacement of the reaction plate relative to the housing in an axial direction is prevented. The groove is arranged on an outside surface of the housing.

A C-clip includes a C-shaped clip body and two peripherally open holes. The clip body can be opened and closed elastically. The peripherally open holes are provided on two lateral sides of the clip body respectively and are adjacent to or located at the two ends of the clip body respectively. The peripherally open holes are provided in the clip body and each have a communication opening and a closed end. A wall between the communication opening and the closed end of each peripherally open hole forms a stop edge for preventing a tip of a retaining ring plier from moving out of the peripherally open hole. The outer diameter of the clip body can be changed by applying forces to the clip body via the peripherally open holes respectively. As the clip body does not have any particularly protruding portion, the C-clip can be used in various situations.
