Definitions
- the invention relates to a plug connection for water-cooled, current-carrying lines, in particular for two-pole high-frequency power lines for induction heating on tools.
- the induction energy caused by induction coils when AC is flowing through is used to heat up electrically conductive or ferromagnetic components.
- An example of an application is the induction welding torch.
- inductive heating it is necessary to continuously cool the live cables to avoid overheating during the operation of the devices. In addition to air cooling, water cooling has prevailed.
- Each of the retaining bolts to be processed consists of a bolt shaft, one end of which is firmly connected to a collar of plates.
- the end face of the plate collar is coated with a dry hot-melt adhesive that can be reactivated by the action of heat.
- the retaining bolts are fed to the tool from a supply via a separating device through a laterally opening feed channel and, when the tool is actuated, are individually conveyed from a kind of waiting position into its mouthpiece such that the end face of the plate collar carrying the hot-melt adhesive faces forward and the retaining bolt by a pneumatic Actuatable plunger on the bolt shaft can be detected, centered and acted upon when the mouthpiece of the tool is pressed flat against a support surface with which the retaining bolt is to be connected.
- An induction coil is accommodated in the mouthpiece of the tool, which surrounds the retaining bolt and in particular the collar of the disc, and is fed with a relatively strong, high-frequency alternating current at the same time as the plunger pressing the retaining bolt against the carrier surface is pneumatically applied.
- the lines carrying the strong, high-frequency induction current must be constantly cooled with water during operation.
- the water-cooled power lines of the induction coils have repeatedly proven to be special problem areas. Because they have to meet particularly high requirements for tightness and dielectric strength. Such tools should also have a high overall impact resistance to external mechanical influences and withstand strong temperature fluctuations without showing any malfunctions. Connection points that are to be provided on the tool must survive the greatest possible number of tool changes without damage.
- the object of the invention is to provide a connector for water-cooled, current-carrying lines on tools and in particular on automated tools to create, which is able to concentrate the power consumption of the induction generator on the inductor and which is quick and easy to operate and meets all requirements for safety, tightness and dielectric strength.
- the plug connection thus ideally ensures the routing of the coolant of the power lines in two separate ways, furthermore a close merging of the two poles to minimize harmful parasitic fields and the use of the coolant to cool the electrical plug connection to minimize the thermal load.
- the inflowing cooling water rinses the electrical lines and flows through the passages provided in the housing and the chambers, so that the electrical plug connections arranged in the housing are also cooled before they reach the Cooling of the induction coil is passed on. Since the chambers and passages provided for cooling are bridged for the return flow, the cooling water flowing back cannot mix in the plug-in connection with the cooling water flowing in and can thus cool down again quickly.
- the chamber in the mother part and the father part is formed in each case by a cup-shaped recess in the housing, which is closed to the outside by a closure piece which is sealed off from the housing wall; in this two openings are provided, into which two metal sleeves are inserted in a sealing manner, one of which, shorter, opens into the chamber and the other, longer extends through the chamber into a bore aligned with the relevant opening in the housing section adjoining the chamber .
- Hoses for the inflow and outflow of the cooling water are pushed onto the ends of the metal sleeves protruding from the closure piece and held by clips.
- the longer metal sleeve extends into the inner bore section of the aligned bore, which is determined by a gradation, and on the father part, the longer metal sleeve protrudes by a certain amount from the smooth, continuous bore; this protruding end fits when the plug connection is joined in a sealed manner into the outer bore section of the aligned bore in the nut part which is determined by a gradation and is sealed therein against the wall by a sealing ring.
- a tubular extension is formed over the end of the metal sleeve protruding from the end face and the contact pins also protruding from the end face, which, when the plug connection is assembled, fits onto the end section of the housing of the mother part facing away from the closure piece and is sealed against it by sealing rings. In this way, a secure connection between the mother and father part of the plug connection can be achieved, which is also absolutely leak-tight.
- three passages for the incoming cooling water are provided, which are offset from one another by 120 °, the passages of the female part being aligned with the passages of the male part in the assembled state of the plug connection; two bores for the electrical contact sleeves or the electrical contact pins and are each offset between the passages by 120 ° to one another drilled a hole for the connections of the water return. This ensures good cooling of the electrical lines and connections.
- the electrical lines routed within the water hoses that supply and transfer the cooling water and the shorter metal sleeves that open into the chambers preferably consist of six wires each, which are divided into two groups of three wires at the level of the mother and father part chambers are then connected to the contact sleeves or the contact pins.
- connection between the mother and father part can be secured by a locking ring with a bayonet or screw lock.
- a mounting ring is fitted in an annular groove on the circumference of the housing of both the mother part and the father part, with the aid of which both parts can be firmly mounted on carrier plates.
