发明名称 ANTI-ROTATION KEY FOR CONNECTOR ASSEMBLY
摘要 In accordance with embodiments of the present disclosure, an improved anti-rotation key designed to prevent rotation of a first threaded portion of a connector assembly with respect to a second threaded portion of the connector assembly is provided. The disclosed key includes several features that facilitate easier, faster, and more accurate securing of the key within the connector. For example, the key may include features that guide, pre-load, and smooth the transition of the key from an initial position to a fully engaged and energized position. Specifically, the key may include a tapered first surface for engaging with a tapered surface of the first threaded portion, and a set of short teeth and a set of long teeth on a second surface opposite the tapered first surface for engaging with an engagement surface on the second threaded portion.

主权项 1. An anti-rotation key for preventing rotation of a first threaded portion of a connector assembly relative to a second threaded portion of the connector assembly, wherein the anti-rotation key comprises: a tapered first surface for engaging with a tapered surface of the first threaded portion; and a plurality of teeth disposed on a second surface opposite the tapered first surface for engaging with an engagement surface on the second threaded portion, wherein the plurality of teeth comprise a set of long teeth and a set of short teeth; wherein the long teeth extend further from a body of the anti-rotation key than the short teeth, and wherein the long teeth are angled with respect to a thickness dimension of the anti-rotation key to guide the anti-rotation key into an energized position against the tapered surface of the first threaded portion as the anti-rotation key is pushed into the connector assembly.
