Abstract

A compensating nut fastener assembly includes a first nut, a second nut, and a torque clip. The second nut receives the first nut. The torque clip is received in the first passage of the first nut and is configured to have a generally triangular cross-section. The torque clip includes a first retaining wall, a second retaining wall, and a third retaining wall. The second retaining wall is connected with the first retaining wall through the first connecting wall and forms a pair of first bending protrusions. The third retaining wall is connected with the second retaining wall through the second connecting wall, and forms a pair of second bending protrusions. The third retaining wall is separate from the first retaining wall and forms a first free end and a second free end, respectively. The three retaining walls are configured to collectively form a fastener channel in contact with a fastener inserted into the fastener channel to retain the fastener in the fastener channel. The two pairs of bending projections contact the inner walls of the two free end first nuts to retain the torque clip in the first channel.

Description

Compensation nut fastening assembly and torque clamp thereof Technical Field The present application relates generally to fastener assemblies, and more particularly to a compensating nut fastener assembly configured to be adapted for compensating for a gap between components (e.g., panels) and torque clips thereof. Background In various industrial applications, components are joined together by use of fasteners. In some applications, there may be gaps between the components. For example, two panels may be separated by a clearance zone or gap in which portions of other components may reside. When the panels are connected together, the fastener assembly may rattle or slip within the gap, thereby creating undesirable noise and providing a loose connection or causing the panels to be compressively deformed by the locking force. Some fastener assemblies employ at least two intermeshing nuts and employ torque clips that are inserted into the innermost nuts and are configured to retain the fasteners (e.g., bolts or screws) as they are inserted into the nuts and cause the nuts to rotate as the fasteners are turned, thereby adjusting the length of the nuts and filling the gap between the panels. Disclosure of Invention According to a first aspect of the present application, there is provided a compensating nut tightening assembly comprising a first nut, a second nut and a torque clip. The first nut defines a first passage through an inner wall thereof. The second nut receives the first nut. The torque clip is received in the first channel of the first nut, the torque clip being configured to have a generally triangular cross-section. The torque clip includes a first retaining wall, a second retaining wall, and a third retaining wall. The second retaining wall is connected with the first retaining wall through a first connecting wall, and the first connecting wall forms a pair of first bending bulges with the first retaining wall and the second retaining wall. The third retaining wall is connected to the second retaining wall by a second connecting wall and is separated from the first retaining wall. The second connecting wall forms a pair of second bending protrusions with the second holding wall and the third holding wall. The first and third retaining walls form a first and second free end, respectively. The first retaining wall, the second retaining wall, and the third retaining wall are configured to collectively form a fastener channel and are configured to contact a fastener inserted into the fastener channel to retain the fastener in the fastener channel. The pair of first bending bosses, the pair of second bending bosses, the first free end and the second free end contact an inner wall of the first nut to retain the torque clip in the first channel of the first nut. In the compensation nut fastening assembly in accordance with the first aspect described above, the first and second connection walls have a gap between them and the fastener received in the fastener passage. In the compensation nut fastening assembly according to the first aspect described above, the ratio of the lengths of the first connecting wall and the second connecting wall to the lengths of the first retaining wall and the second retaining wall is 10% to 50%. In the compensation nut fastening assembly according to the first aspect described above, the first retaining wall, the second retaining wall, and the third retaining wall are straight walls. In the compensation nut fastening assembly in accordance with the first aspect described above, the top portions of the first, second and third retaining walls are provided with guide flares. In the compensation nut tightening assembly according to the first aspect described above, the torque clip is provided with a hollowed-out portion that penetrates the torque clip in a thickness direction of the torque clip. In the compensation nut fastening assembly according to the first aspect, the hollow portion includes a first hollow portion and a second hollow portion. The first hollowed-out part extends from the first connecting wall to the first retaining wall and the second retaining wall. The second hollowed-out part extends from the second connecting wall to the second retaining wall and the third retaining wall. In the compensation nut tightening assembly according to the first aspect described above, the torque clip is integrally made of metal. According to a second aspect of the present application, there is provided a torque clip for compensating a nut tightening assembly comprising a first retaining wall, a second retaining wall and a third retaining wall.
