A connecting assembly for connecting a first body and a second body. The first body includes multiple grooves formed on an outside of the first body near a connecting end. The connecting assembly includes a connector. The connector includes multiple connecting segments arranged circumferentially around a central longitudinal axis; and a first jaw formed on an inside of the segments. The first jaw includes multiple teeth. Each tooth includes: a leading side facing an axial center of the connector; a top side; and a trailing side opposite the leading side. A tooth height is measured between a base of the tooth and an intersection between the leading side and the top side of the tooth. At least two of the tooth/groove pairs have a difference between tooth height and groove depth that are different from each other.

Collet-type wellhead connector system

A connecting assembly for connecting a first body and a second body includes a connector having a plurality of segments and a main piston positioned around at least a portion of the connector. The connector includes: a channel that extends longitudinally through the connector from a first end to a second end; a plurality of teeth formed on an inside of the connector near the first end and near the second end; a first jaw formed of at least one teeth near the first end; and a second jaw formed of at least one teeth near the second end and axially spaced apart from the first jaw. Each of the plurality of teeth has a leading side facing an axial center of the connector, a top side, a contact point at a transition between the leading side and the top side, and a trailing side opposite the leading side. The teeth of the second jaw include: a first tooth axially closer to the axial center of the connector than the remaining teeth of the second jaw and an end tooth axially farther from the axial center of the connector than the remaining teeth of the second jaw.
