  • the invention relates to a connection device for connecting an electrical conductor to a spring-cage terminal, the connection device having an output body, a conveyor device and a fixing device.
  • the dispensing body comprises a dispensing opening for dispensing the electrical conductor, the dispensing body having an elongate tube segment through which runs a guide path for the electrical conductor, and the dispensing opening being formed on the elongate tube segment and the elongate tube segment terminating at the end and immediately above a connection opening of the spring terminal can be positioned.
  • the conveying device is set up to convey the electrical conductor through the dispensing opening of the dispensing body.
  • the fixing device is set up to fix the electrical conductor, the fixing device having clamping means for clamping the electrical conductor.
  • the invention relates to a method for connecting an electrical conductor to a spring-loaded terminal by means of a connecting device.
  • the method includes receiving the electrical conductor to be connected by a connection unit of the connection device.
  • the method also includes conveying the electrical conductor by means of a conveying device of the connecting device, so that a contacting section of the electrical conductor protrudes from a dispensing opening of a dispensing body of the connecting unit, with the electrical conductor being moved along a guide path when conveyed by the conveying device, which is in an elongate tube segment of the dispensing body, the connection unit is moved by means of a positioning device of the connection device or the electrical conductor is conveyed out of the dispensing opening by means of the conveying device, so that the contacting section of the electrical conductor is pressed into a connection opening of the spring-cage terminal in order to connect the electrical conductor to the spring-cage terminal, and the fixing of the electrical conductor by means of a fixing device of the connection device.
  • spring-loaded terminals are increasingly being used, in which a contacting section of the electrical conductor is to be pressed into a connection opening of the spring-loaded terminal in order to provide a mechanically resilient and electrically conductive cable connection.
  • connection devices are known, for example, in which an end section of a cable to be connected is held by gripper fingers and pressed into a connection opening of a spring-loaded terminal.
  • connection devices are not suitable for laying the connected cable on a mounting plate, since due to the construction of the gripping fingers, there is an increased risk of the cable and the gripping fingers coming out of contact in some laying directions.
  • the object on which the invention is based is therefore to enable automated connection of an electrical conductor to a spring-loaded terminal by means of a controllable connection device and to avoid connection and laying errors as far as possible.
  • connection device of the type mentioned at the outset, the clamping means being arranged within the elongated pipe segment.
  • the invention makes use of the knowledge that the elongate tube segment of the dispensing body serves as a guide tube for the electrical conductor.
  • the electrical conductor is guided on all sides in the radial direction and thus circumferentially through the elongated tube segment. Since the surrounding tube segment, unlike lateral gripping fingers, does not have a lateral gap, the electrical conductor cannot become detached from the output body during laying, regardless of the laying direction, so that laying errors are effectively avoided.
  • the electrical conductor can, for example, be in the form of a cable and/or comprise one or more wires, cores and/or strands.
  • the electrical conductor preferably has a wire-end ferrule or an ultrasonically welded end region, which extends through the connection device into a connection opening of the spring-loaded terminal can be pushed in.

  • the dispensing opening is formed on the elongated tube segment.
  • the dispensing opening preferably closes off the elongate tube segment at the end.
  • the dispensing body is preferably inserted into a carrier device of the connection device so that it can be detached without being destroyed.
  • the dispensing body is thus exchangeable.
  • Different tube segment lengths and/or different diameters at the dispensing opening and/or in the area of the guide path within the elongate tube segment can be advantageous for connecting different electrical conductors, which can differ, for example, in terms of their cross section and/or their resilience or flexibility. Due to the interchangeability of the output body, the configuration of the output body can be adapted to an electrical conductor to be connected or to a group of electrical conductors to be connected.
  • the connecting device has a fixing device.
  • the fixing device is set up to fix the electrical conductor.
  • the fixing device is preferably actuated before the contacting section of the electrical conductor is pressed into the connection opening of the spring-loaded terminal.
  • the fixing device has clamping means for clamping the electrical conductor, with the clamping means being arranged inside the elongate tube segment.
  • the clamping means can be designed as elastically deformable gripping elements.
  • the clamping means are designed as gripping arms. Because the clamping means are within the elongate pipe segment, on the one hand the compressive forces when pressing the contact section of the electrical conductor into the connection opening of the spring-cage terminal can be absorbed and on the other hand a safe lateral guidance when laying the electrical conductor on the mounting plate after connecting the electrical conductor to the spring-cage terminal can be guaranteed.
  • the clamping means and the elongate tube segment can be moved relative to one another in the axial direction in order to actuate the fixing device.
  • the elongate tube segment preferably has an inner cone or an inner cross-sectional reduction, with the clamping means sliding along the inner cone or the cross-sectional reduction when the fixing device is actuated and being elastically bent inward by the inner cone or the cross-sectional reduction in the direction of the electrical conductor . In this way, the free cross-section between the clamping means of the fixing device is reduced when the fixing device is actuated, until the clamping means come into contact with the electrical conductor.
  • the fixing device is preferably coupled to a controllable actuating device, by means of which the relative movement of the clamping means and the elongate tube segment can be implemented in the axial direction.
  • the actuating device can comprise a mechanical, electrical, pneumatic or hydraulic actuating drive.
  • the actuating drive can be connected to a control device of the connection device, so that the fixing device is controlled in accordance with a connection routine when an electrical conductor is automatically connected to a spring-cage terminal.
  • a connection device is also advantageous in which the conveyor device has one or more conveyor rollers.
  • the one or more conveyor rollers can be driven in rotation by a conveyor drive.
  • the one or more conveyor rollers are also configured to be in contact with the electrical conductor and to move the electrical conductor longitudinally by a rotational movement.
  • the one or more conveyor rollers are preferably mounted pneumatically.
  • the one or more conveyor rollers can preferably be positioned in such a way that they exert pressure on the electrical conductor.
  • the pressure load improves the conveying precision and the conveying quality, since the tendency of the one or more conveying rollers to slip is significantly reduced.
  • the one or more conveyor rollers have a structured surface in the contact area for the electrical conductor.
  • the surface of the one or more conveyor rollers can include grooves or grooves, as a result of which the tendency to slip is further reduced.
  • the conveyor device has two conveyor rollers arranged next to one another, with a contact path for the electrical conductor running between the peripheral surfaces of the two conveyor rollers.
  • the peripheral surfaces of the two conveyor rollers are in contact with the electrical conductor when the electrical conductor is being conveyed. Reliable and precise conveying of the electrical conductor can be ensured by the contact path defined by the two conveying rollers arranged next to one another.
  • connection device is further developed advantageously in that the distance between the conveyor rollers arranged next to one another can be changed in order to adjust the width of the contact path.
  • the two conveyor rollers arranged next to one another are preferably coupled to an adjusting drive, by means of which the distance between the conveyor rollers arranged next to one another can be changed.
  • the adjustment drive is preferably connected to a control device of the connecting device, via which the adjustment drive can be controlled.
  • the adjustment drive can be a mechanical, electrical, pneumatic or hydraulic adjustment drive.
  • the dispensing body, the conveying device and/or the fixing device are part of a connecting unit, the connecting unit being movable and positionable by means of a positioning device.
  • the connection unit can be moved in a translatory and/or rotary manner, for example.
  • the positioning device thus allows the contacting section of the electrical conductor to be aligned directly in front of the connection opening of the spring-cage terminal and the contacting section of the electrical conductor to be pressed into the connection opening of the spring-cage terminal.
  • the positioning device can be an industrial robot, for example, and the connection unit can be attached to an arm of the industrial robot.
  • the industrial robot can be, for example, a multi-axis articulated arm robot, in particular a 6-axis articulated arm robot.
  • the connection device has a control device which is set up to control the conveyor drive of the conveyor device and the positioning device for laying the electrical conductor as a function of one another.
  • the control of the conveyor drive of the conveyor device and the positioning device as a function of one another takes place in particular after the electrical conductor has been connected to a spring-loaded terminal.
  • the spring-loaded terminal is preferably arranged on a mounting plate, with the electrical conductor being laid on the mounting plate after it has been connected to the spring-loaded terminal.
  • the conveyor drive of the conveyor device is then controlled as a function of the movement of the connection unit caused by the positioning device.
  • the electrical conductor is not pulled out of the connection device by a tensile force, but is actively tracked by the conveying device. In this way, a tensile load on the electrical conductor during the laying process is avoided. The risk of damage to the electrical conductor is therefore significant reduced.

  • laying in an outer area of a curve was previously not possible, since the tensile force required to pull the electrical conductor out of the connection device can only be generated when laying it along the inner area of a curve.
  • connection device in a further preferred embodiment, it comprises a detection device which is set up to determine the position of a connection opening on the spring-cage terminal, with the control device preferably being set up to use the positioning device for positioning the dispensing opening of the dispensing body on the connection opening of the spring-cage terminal in To control dependence of the signals of the detection device.

  • connection device is advantageous in which the detection device comprises a camera and is set up to determine the position of the connection opening of the spring-loaded terminal by evaluating one or more images recorded by the camera. For example, the connection unit is roughly positioned without using the detection device. After the rough positioning of the connection unit has been completed, an image recording is then generated, which is used for the fine positioning of the connection unit.

If a jam has occurred, the conveying resistance increases, so that there is an increased power consumption at the conveyor drive of the conveying device.
  • the jamming of the contact section can be determined in this case.
  • the conveying direction of the conveying device can be reversed after the contacting section has been jammed, in order to check whether the contacting section can still be pulled out of the connection opening. If the contacting section is already jammed, it is not possible to pull out the contacting section, so that the current consumption of the conveyor drive of the conveyor device increases excessively when the conveying direction is reversed. A corresponding pull-out test can be used to determine whether the jamming was successful.
