Abstract

Improved electric cable swivel assemblies and related fabrication methods are provided. More particularly, the present disclosure provides improved electric cable swivel assemblies configured to reduce entanglement of swimming pool cleaner power cables, and related cable swivel fabrication methods. In exemplary embodiments, the present disclosure provides for a electric cable swivel assembly including a swivel body/housing that is configured and dimensioned to mount with respect to a first cable and a second cable. The swivel body/housing is configured to provide a continuous electrical contact between the first and second cables, wherein the first and second cables are generally axially rotatable relative to each other. Methods of overmolding and/or otherwise fabricating the swivel are disclosed herein.

Claims23

Dependent claims

An electric cable swivel assembly comprising:

a housing that extends from a first end to a second end;
a seal member configured to mount with respect to the second end of the housing, the seal member extending from a first end to a second end and having an aperture that extends from the first end to the second end;
a shaft assembly having an outer member extending from a first end to a second end and having the second end of the outer member mounted with respect to a shaft member and to a first cable assembly associated with a first cable, the shaft member configured to be at least partially housed within the aperture of the seal member and rotatable relative to the seal member and to the housing when the seal member is mounted with respect to the housing;
an electrical contact assembly extending from a first end to a second end, the second end of the electrical contact assembly mounted with respect to the first end of the outer member;
a support member extending from a first end to a second end and having:
(i) the first end of the support member mounted with respect to a second cable assembly associated with a second cable, and (ii) the second end mounted with respect to the first end of the electrical contact assembly;
and
an overmold member positioned over at least a portion of the housing and the support member, the overmold member configured to hermetically secure the housing and the support member;
wherein the electrical contact assembly provides a continuous electrical contact between the first cable and the second cable;
and
wherein the first cable can rotate axially relative to the second cable.

8 more elements

A method for fabricating an electric cable swivel assembly for a swimming pool cleaner power cable comprising:

providing a housing that extends from a first end to a second end;
providing a seal member, the seal member extending from a first end to a second end and having an aperture that extends from the first end to the second end;
mounting the seal member with respect to the second end of the housing;
providing a shaft assembly having an outer member extending from a first end to a second end;
mounting the second end of the outer member with respect to a shaft member and to a first cable assembly associated with a first cable;
housing at least a portion of the shaft member within the aperture of the seal member so that the shaft member is rotatable relative to the seal member and to the housing after the seal member is mounted with respect to the housing;
providing an electrical contact assembly extending from a first end to a second end;
mounting the second end of the electrical contact assembly with respect to the first end of the outer member;
providing a support member extending from a first end to a second end;
mounting the first end of the support member with respect to a second cable assembly associated with a second cable;
mounting the second end of the support member with respect to the first end of the electrical contact assembly;
and
overmolding an overmold member over at least a portion of the housing and the support member to hermetically secure the housing and the support member;
wherein the electrical contact assembly provides a continuous electrical contact between the first cable and the second cable;
and
wherein the first cable can rotate axially relative to the second cable.
