Definitions
- Power socket for a detachable connection to a power plug and power coupling consisting of such a power socket and an associated power plug
- the invention relates to a power socket for a detachable connection to a power plug, with a base body made of electrically conductive material with a hole for receiving a substantially cylindrical bolt of the power plug and with a device for connection to a power cable, with a helical shape in the base body Groove is arranged to receive a locking lug of the power plug, the base body having a sleeve with the helical groove and a receptacle for the sleeve.
- the present invention also relates to a power coupling consisting of such a power socket and an associated power plug.
- the term "essentially cylindrical" is intended to clarify that the hole in the base body of the power socket as well as the bolt of a matching power plug can also deviate slightly from the rotationally symmetrical shape and, for example, be designed slightly eccentric.
- Such power sockets together with suitable power plugs, represent power couplings which are designed to transmit high currents of up to several hundred amperes.
- power couplings are used in welding systems to conduct high welding currents from the welding power source to the welding torch and to the workpiece.
- the standard DIN EN 60974-12 “Plug connections for welding cables” exists for these connections, which are common in welding technology.
- power sockets can also be used in other applications, for example photovoltaic systems or battery chargers, as part of corresponding power couplings for transmitting the direct current from solar modules or the charging current to the Charging batteries can be used.
- connectors from DINSE Ges. are often used for power cable couplings and hose package couplings.
- m. b. H . which are known to those skilled in the field of welding technology as so-called DINSE® plugs, DINSE® sockets or DINSE® connectors.
- DINSE® Connector With the DINSE® Connector, a plug with a locking lug is inserted into a socket with a helical groove of approx. 270° rotation angle and a pitch of around 4 mm per 360°.
- the thread-like interaction between plug and socket results in a certain preload force. a tightening torque of the connection or a corresponding axial force that holds the plug connection in its connected state.
- the plugs and sockets have different cross-sections.
- the inert gas or plasma-compatible medium is also guided through appropriate channels in the center of the power coupling.
- the relatively high pitch of the helical groove in current sockets of the prior art together with a small preload length (that length of the plug connection which extends from the power contact surface between the power plug and the power socket and the locking lug of the power plug) and a high preload surface (that area of the Power socket or the bolt cross section of the power plug, which is loaded with a force) of the connection result in an extremely steep preload characteristic, i.e. a high gradient in the force-path curve of the plug connection.
- power sockets have been further developed by using a spring-loaded locking lug on the plug to reduce the release energy or the release torque of the connection is significantly increased.
- a power coupling is described, for example, in WO 2016/128557 A1, wherein the power plug of the power coupling has a displaceably mounted locking bolt which is held in a basic position by means of a spring device.
- the disadvantage of this plug is that due to the construction in the center of the power plug, a hole or a cavity in the axial direction for guiding a gas cannot or cannot be easily realized.
- the solution complexity is located in the power plug, which is usually exposed to harsher environmental conditions than the socket and is also located in the more price-sensitive part of the power coupling.
- FR 2 270 695 Al discloses a power socket of the present type, the base body having a sleeve with the helical groove and a receptacle for the sleeve.
- the object of the present invention is to create an above-mentioned power socket for couplings for transmitting high currents of up to several 100 A, as can occur, for example, in welding systems, photovoltaic systems or battery chargers, which ensures the lowest possible contact resistance and thus optimal current transfer the risk of local overheating of the power socket and the power plug ckers prevented or at least minimized by impermissibly high current densities.
- the power socket should be as simple and cost-effective as possible to produce and also contain a protective gas or the like. enable in the center. Disadvantages of known power sockets should be avoided or reduced.
- the object according to the invention is achieved by an above-mentioned power socket, the helical groove having at least two areas with a positive gradient, and at the end of each area with a positive gradient, areas with a negative gradient are arranged to form a locking step, the receptacle being made of Metal or a metal alloy with a coating made of electrically insulating material and the sleeve is made of harder material than the receptacle.
- the operator can be given haptic feedback when the respective locking level is reached.
- a higher release torque than the tightening torque can be achieved, which means that the power coupling can no longer be released unintentionally as easily.
- the contact resistance can also be reduced and the risk of destruction or impairment of the power socket, the power plug, the power cable or the devices connected to it as well as the risk of injury due to excessive temperature and a negative influence on the respective process, for example the welding process, be reduced.
- the measures on the power socket allow connection to conventional power sockets. ckers, for example the above-mentioned DINSE® connectors, and do not require the replacement of the connectors of conventional components, such as welding components.
- a further advantage of the present power socket is that the space around the central axis of the power socket can be kept free of structural measures, whereby a hole or a cavity is created in the center of the power socket, for example for guiding a protective gas, a plasma-capable medium, a welding wire or the like. can be easily provided. Because the technical features for solving the problem according to the invention are arranged in the power socket, the costs required for this can be shifted from the more cost-sensitive part of the power coupling, the power plug, into the power socket. In addition, the power socket is usually located in the respective device, for example in the welding power source, and is less exposed to harsh environmental conditions than the power plug. But the necessary design measures on the power socket can also be implemented relatively easily and inexpensively.
- a spring element is arranged in the receptacle for the sleeve of the base body for resilient mounting of the sleeve in the axial direction of the receptacle of the base body, a further improvement in the connection between the power socket and a corresponding power plug and thus a lower contact resistance of the power coupling can be achieved.
- the spring force allows the loosening torque to be further increased compared to the tightening torque of the plug connection, thus further reducing the risk of the power plug being unintentionally released from the power socket. Thermal cycles, vibrations and impacts can no longer loosen the plug connection.
- the contact force of the power connection and thus the contact resistance can be influenced.
- the force effect on the contact surface can be adjusted in the respective locking level via the spring element. A force effect on the contact surface of 5 to 50 N/mm 2 is preferred.
- the spring element is formed by at least one wire spring washer.
- a wire spring washer is very cost-effective because it is arranged in a corrugated manner Flat wire can be produced and can be arranged in the power socket in a particularly space-saving manner without the central area of the socket being required and thus for the conduction of a protective gas or the like. can be available.
- the spring element is advantageously formed by two wire spring washers and a spacer ring arranged between the wire spring washers.
- the spacer ring prevents the spring travel of the wire spring washers arranged on both sides of it from being reduced by twisting the wire spring washers relative to one another and the entire spring force of the wire spring washers can therefore be utilized.
- the sleeve has positioning elements, in particular axial locking lugs, to prevent rotation relative to the receiving base body of the power socket.
- positioning elements on the sleeve are easy to implement and do not significantly increase the manufacturing costs.
- the receptacle for the sleeve of the base body of the power socket can consist of two parts that can be connected to one another. This means that the power socket can be assembled very quickly and easily by simply placing the necessary components, the sleeve and all the necessary spring elements, at designated locations in the parts of the receptacle of the base body of the power socket and then connecting the parts to one another.
- the two parts of the receptacle of the base body can preferably be connected to one another via a press fit.
- the parts of the receptacle of the base body can also be releasably connected to one another, for example via a screw connection with a left-hand or right-hand thread.
- the receptacle of the base body can in particular be made of steel or a steel alloy or of brass or a brass alloy.
- the sleeve of the power socket is preferably made of steel or a steel alloy. This has the advantage that wear occurs primarily on the softer power plug and not on the harder sleeve of the power socket.
- the holder of the base body has a flat end face for contacting for optimal current transfer to the power plug. Due to the flat design of the end face of the holder, a uniform low contact resistance can be achieved over the entire contact surface. This prevents areas on the contact surface with higher contact resistance, which can lead to local overheating due to particularly high current densities. If a protective gas or the like passes through the power socket. is guided, the area around the central axis is left out and therefore the end face is preferably annular.
- the end face of the receptacle of the base body can have a coating, for example a silver coating.
- Coatings made of zinc or gold are also possible for low contact resistance.
- Coatings made of phosphate only in combination with other chemical substances protect the contact surface from corrosion.
- the groove in the sleeve extends over a rotation angle of 90° to 270°. Such angles of rotation are suitable for handling the power coupling.
- the pitch of the positive pitch areas of the groove is ideally between 1mm and 8mm per 360°. These values are suitable for a suitable connection of the power socket to a suitable power plug with the locking lug.
- the gradient of the areas of the helical groove with a positive gradient does not necessarily have to be constant, but can also be graded, for example increasing or flattening.
- the pitch of the areas of the groove with a negative pitch to form the locking steps is between 0.1 mm and 20 mm, preferably between 1 mm and 20 mm, particularly preferably between 5 mm and 20 mm per 360 °.
- the pitch of the areas of the helical groove in the sleeve can also be graded with a negative pitch.
- the helical groove after the areas with a negative slope, can also have areas without or without any significant gradient.
- grading between the areas with a negative gradient and the areas without a gradient a smooth transition between these areas of the helical groove can be achieved. Such transitions can positively influence the user's haptic perception.
- the device for connecting to a power cable can be formed by a screw connection. This represents a simple and cost-effective implementation of the connection between the power cable and the power socket.
- the base body of the power socket has a continuous hole or the like in the axial direction.
- a protective gas or plasma-compatible medium can be passed through the power contact.
- a rotationally symmetrical bore it can be used to guide the protective gas or the like.
- a differently shaped cavity can also be provided in the receptacle of the base body in the axial direction.
- the object according to the invention is also achieved by a power coupling consisting of a power socket described above and an associated power plug with a substantially cylindrical bolt. Please refer to the above description of the power socket for the advantages that can be achieved in this way.
- the sleeve of the power socket is made of harder material than the cylindrical bolt of the power plug, wear occurs preferably on the softer power plug and not on the harder sleeve of the power socket.
