Abstract: The present invention relates to a boot and connector assembly. The boot has a through hole passing therethrough and a boot body enclosing the through hole, the boot body comprising: a neck sealing portion presenting a substantially cylindrical shape, wherein the neck sealing portion has an inner diameter maintained substantially constant; a body portion located at the proximal side of the neck sealing portion and presenting a generally cylindrical shape, wherein the body portion has an inner diameter and an outer diameter that are both greater than the inner diameter and the outer diameter of the neck sealing portion; and a gap passing portion connecting the neck sealing portion to the body portion and having a substantially frustoconical shape, wherein the gap passing portion has an inner diameter gradually increasing from the inner diameter of the neck sealing portion to the inner diameter of the body portion, and an outer diameter gradually increasing from the outer diameter of the neck sealing portion to the outer diameter of the body portion. The boot of the present disclosure effectively solves the problem that the boot interferes with other components so that the boot is unable to extend to the antenna panel when the mounting space is small, and also has the advantages of simple to manufacture, convenient to mount and high efficiency.

Abstract: A fixture for testing coaxial connectors for PIM includes: (a) an adapter connector comprising an inner contact; an outer body that circumferentially surrounds and that is spaced from the inner contact, the outer body including an inner ring and an outer ring with a gap therebetween; and a resilient member in electrical contact with the outer body; and (b) a foundation including a fixed sleeve and a biasing member, the biasing member exerting an axial force on the sleeve and the outer body, the biasing member permitting axial and radial adjustment of the outer body and inner contact relative to the sleeve. The gap between the inner and outer rings of the outer body is configured to receive an outer ring of an outer body of a coaxial connector to be tested. The inner ring of the test fixture is located to be radially outward of an inner ring of the outer body of the coaxial connector to be tested. The resilient member is positioned to apply radial pressure to the inner ring of the outer body of coaxial connector to be tested.
