Protective sleeve for fluid connectors

Abstract

A protective sleeve for a fluid connector is integrally molded from an elastic material and includes a central section and two end sections along the axial direction. The outer and inner diameters of the end sections are smaller than those of the central section, creating internal accommodating spaces of varying sizes along the axial direction. The inner circumferential surface features a segmented inner diameter structure, including a smaller inner diameter section, a larger inner diameter section, and a transition section connecting the two, resulting in a continuously varying inner diameter. Therefore, when the sleeve is fitted onto the outer circumference of the connector, its elastic deformation and recovery properties allow it to conform to and cover the outer circumference of the connector, maintaining coverage and protection of the outer circumference and the mating area before and after connector engagement. This structure improves operational convenience, reduces the contact of external contaminants with the outer circumference of the connector, and is applicable to fluid connectors of various specifications.

Claims

1. A protective sleeve for a fluid connector, comprising: a sleeve integrally formed from an elastic material, and including a central section along the axial direction and first ends respectively disposed on both sides of the central section; wherein, Each of the first ends is integrally connected to the central section, and the outer diameter of each of the first ends is smaller than the outer diameter of the central section, and the inner diameter of each of the first ends is smaller than the inner diameter of the central section; the sleeve body has an inner circumferential surface, and the inner circumferential surface is sequentially formed along the axial direction by a first inner diameter segment at the first end, a second inner diameter segment at the central section, and a transition segment between the first inner diameter segment and the second inner diameter segment and connecting the two, such that the inner diameter of the first inner diameter segment is smaller than the inner diameter of the second inner diameter segment, and the inner diameter changes continuously along the axial direction; when the sleeve body is fitted onto the outer circumference of the joint, the first inner diameter segment and the second inner diameter segment respectively fit against the outer circumference of the joint, so that the sleeve body covers the outer circumference of the joint.

2. The protective sleeve for the fluid connector as described in claim 1, wherein, The transition section is composed of inclined or curved surfaces.

3. The protective sleeve for the fluid connector as described in claim 1, wherein, The first end has an outwardly extending annular flange.

4. The protective sleeve for the fluid connector as described in claim 1, wherein, When the sleeve body is fitted onto the joint, it applies radial holding force to the outer periphery of the joint through elastic deformation and recovery.

5. A protective sleeve for a fluid connector as described in claim 1, wherein, The sleeve body can simultaneously cover the outer periphery of both the first joint and the second joint, which are in a engaged state.
