A linear actuator system comprising a linear actuator having a housing and an outer tube, which with a rear end is secured to a side of the housing at a front end thereof. The outer tube surrounds an electric motor driven spindle unit and an activation element. The linear actuator system further comprises a control box having a control, where the control box is arranged in the angle between the housing and the outer tube on the linear actuator. The control box is fastened with a mounting bracket to the outer tube on the linear actuator. The mounting bracket comprises a tubular portion, whereby it can be pushed in over the outer tube and the mounting bracket and the control box are also designed with interacting fastening means for fastening the control box to the mounting bracket. The tubular portion of the mounting bracket has an axially extending slit and the interacting fastening means between the mounting bracket and the control box are constituted on both sides of the slit. The interacting fastening means are designed such that when the control box is fastened onto the mounting bracket, the slit contracts so that the tubular portion of the mounting bracket tightens around the outer tube on the linear actuator. The construction is characterized in that the control box is only fastened to the mounting bracket on the outer tube of the linear actuator. This simplifies the fastening quite considerably while simultaneously simplifying the design.
A linear actuator system comprising a linear actuator with a housing, an electric motor with a transmission a spindle unit an activation element in connection with the spindle unit and wherein the electric motor via the transmission drives the spindle unit by means of which the activation element moves back and forth depending on the direction of rotation of the electric motor, and an outer tube which protrudes from a side of the housing at a front end thereof, and comprising a control box with a guide, and wherein the control box is arranged in the angle between the housing of the linear actuator and the outer tube and a mounting bracket and wherein the control box with the mounting bracket is secured to the outer tube of the linear actuator, and wherein the mounting bracket comprises a tubular portion that can be slid over the outer tube and that the mounting bracket and the control box have interacting fastening means for fastening the control box to the mounting bracket, wherein the tubular portion of the mounting bracket has an axially extending slit and that the part of the interacting fastening means between the mounting bracket and the control box is formed on both sides of the slit, and in that the interacting fastening means are designed such that when the control box is secured to the mounting bracket, the slit contracts such that the tubular portion of the mounting bracket tightens around the outer tube on the linear actuator.
