Abstract

Claims (52)

1 . A linear actuator comprising:

a housing having a first end configured to be coupled to a first component;

a rod configured to extend from a second end of the housing and configured to be coupled to a second component;

a cable extending from the first end of the housing; and

a pivot ear coupled to the first end of the housing, the pivot ear being configured for pivotable attachment to a mounting bracket configured to couple the first end of the housing to the first component;

wherein a first shroud that is integral with the pivot ear extends past the first end of the housing and covers at least part of the cable;

wherein the pivot ear comprises a lower end connected to the first end of the housing and an upper surface opposite the lower end;

wherein a channel is formed as an indentation in the upper surface of the pivot ear and in an upper surface of the first shroud;

wherein the channel is configured to receive the cable; and

wherein as the housing pivots with respect to the mounting bracket, the cable is guided within the channel over the upper surfaces of the pivot ear and the first shroud.

2 . The linear actuator of claim 1 , wherein the housing comprises a longitudinal side surface connecting the first and second ends of the housing; and

wherein the linear actuator further comprises a second shroud that is an extension of the longitudinal side surface.

3 . The linear actuator of claim 2 ,

wherein the second shroud is aligned with the cable and the pivot ear and over the channel.

4 . The linear actuator of claim 1 , further comprising the mounting bracket, the mounting bracket comprising:

a mounting flange configured to be coupled to the first component; and

a clevis comprising a pair of forks pivotably coupled to the first end of the housing, wherein the cable is routed between the clevis forks and through an opening in the mounting flange; and

a hood that extends from the mounting flange at least partially along the clevis forks so as to cover at least part of the cable.

5 . The linear actuator of claim 4 , wherein the mounting flange comprises a first face configured to be attached adjacent to the first component and an opposite second face; and

wherein the hood extends outwardly past the second face of the mounting flange.

6 . The linear actuator of claim 1 , wherein the linear actuator is a trim tab actuator, the first component is a boat, and the second component is a trim tab.

7 . The linear actuator of claim 1 , wherein the housing is defined in a longitudinal direction extending from the first end to the second end thereof and in a lateral direction extending from a front of the housing to a rear of the housing; and

wherein the cable is guided within the channel over the upper surfaces of the pivot ear and the first shroud in both the longitudinal and lateral directions as the housing pivots with respect to the mounting bracket.

8 . The linear actuator of claim 1 , further comprising a bolt;

wherein the pivot ear comprises a hole through which the bolt is inserted so as to pivotably connect the pivot ear to the mounting bracket; and

wherein the upper surface of the pivot ear routes the cable around the bolt.

9 . A linear actuator comprising:

a mounting bracket comprising:

a mounting flange configured to be coupled to a first component; and

a clevis comprising a pair of forks;

a housing having a first end configured to be pivotably coupled to the clevis forks;

a rod configured to extend from a second end of the housing and configured to be coupled to a second component;

a cable extending from the first end of the housing and routed between the clevis forks and through an opening in the mounting flange;

a hood on the mounting bracket that extends from the mounting flange at least partially along the clevis forks so as to cover at least part of the cable;

a pivot ear pivotably coupling the first end of the housing to the clevis forks; and

a first shroud that is integral with the pivot ear and extends past the first end of the housing and covers at least part of the cable;

wherein the pivot ear comprises a lower end connected to the first end of the housing and an upper surface opposite the lower end;

wherein a channel is formed as an indentation in the upper surface of the pivot ear and in an upper surface of the first shroud;

wherein the channel is configured to receive the cable; and

wherein as the housing pivots with respect to the mounting bracket, the cable is guided within the channel over the upper surfaces of the pivot ear and the first shroud.

10 . The linear actuator of claim 9 , wherein the housing comprises a longitudinal side surface connecting the first and second ends of the housing; and

wherein the linear actuator further comprises a second shroud that is an extension of the longitudinal side surface.

11 . The linear actuator of claim 10 ,

wherein the second shroud is aligned with the cable and the pivot ear and over the channel.

12 . The linear actuator of claim 9 , wherein the mounting flange comprises a first face configured to be attached adjacent to the first component and an opposite second face; and

wherein the hood extends outwardly past the second face of the mounting flange.

13 . The linear actuator of claim 9 , wherein the linear actuator is a trim tab actuator, the first component is a boat, and the second component is a trim tab.

14 . The linear actuator of claim 9 , wherein the housing is defined in a longitudinal direction extending from the first end to the second end thereof and in a lateral direction extending from a front of the housing to a rear of the housing; and

wherein the cable is guided within the channel over the upper surfaces of the pivot ear and the first shroud in both the longitudinal and lateral directions as the housing pivots with respect to the mounting bracket.

15 . The linear actuator of claim 9 , further comprising a bolt;

wherein the pivot ear comprises a hole through which the bolt is inserted so as to pivotably connect the pivot ear to the clevis forks of the mounting bracket; and

wherein the upper surface of the pivot ear routes the cable around the bolt.
