Definitions
- the invention relates to a method for connecting a rigid contact body to a flexible conductor piece consisting of partial conductors, the contact body and the flexible conductor piece forming an assembly of a current path of a switching device.
- Modules of the type mentioned are part of many electrical switching devices, in particular those in which the rigid contact body is arranged to be movable and can be actuated by an anti-mechanical device to switch the switching device on and off (EP 0 756 752 B1).
- the rigid contact body provided with a contact pad interacts with a relatively fixed counter contact.
- a relatively stationary arrangement is understood to mean that a component designated herewith is part of a switching device to which the movable contact arrangement belongs.
- the switching devices considered here include multi-pole low-voltage circuit breakers with a rated current 1 up to several 1000 A, which have several or a large number of contact cores per pole. With such circuit breakers, the costs for connecting the contact bodies to the flexible conductors represent a not inconsiderable part of the total production costs. Based on this, the object of the invention is to create a method of the type mentioned at the outset which compares the manufacture of the above-mentioned assemblies enables low costs.
- a first part-length of a section of a semi-finished product used to produce the flexible conductor piece can be brought into contact with a contact surface of the contact body provided for the connection, and the part-length mentioned can be mechanically compressed by a pressing force acting against the contact surface.
- Contact bodies are produced by mechanical compression of a first partial length of a section of a semifinished product used to manufacture the flexible conductor piece, while the flexible conductor piece is formed by a second partial length of the section of said semifinished product excluded from compression.
- the advantage of this method is that the assembly consisting of a contact body and a flexible conductor is made of Finally, the semi-finished product is needed, which is used for the production of the flexible conductor pieces.
- a further advantageous embodiment of the above method makes it possible to facilitate the integration of the modules considered here into a switching device.
- a connection piece serving for connection to a relatively fixed conductor of the switching device is formed by mechanical compression of a third part of the section of the semi-finished product.
- the method in which the use of a finished contact body is assumed can be carried out using a compression mold with a chamber for receiving an end part of the contact body and the first part length of the semi-finished product, and with an opening for the first part length, the pressing force being exerted by means of an associated ram.
- the method can advantageously be carried out using a press mold with a chamber corresponding to the contact body and an opening for opening the first part of the section of the semi-finished product.
- Both of the aforementioned types of method can also be used to produce a contact arrangement with two or more flexible conductor pieces.
- a press mold with an exit opening dimensioned according to the entire cross section of the conductor pieces can be used.
- the rigid contact bodies are provided with a contact pad which is dimensioned accordingly for the respective switching contacts.
- a contact pad can be at least partially embedded in the semi-finished product during the compression of the semi-finished product.
- the Contact pad be provided with at least one extension intended for embedding the semi-finished product.
- the semi-finished product used in the invention e.g. strands of copper wire, which has a clean and uniform quality which is customary for electrical engineering purposes
- the semi-finished product used may be locally contaminated and / or partially oxidized during storage or during manufacture. If such material is processed in the course of automated production, parts that deviate from the specified quality standard can be produced without this being externally recognizable. The cause can e.g. Inclusions and insufficient bonding.
- quality deviations of the type described can be avoided by carrying out the mechanical compression in the presence of a flux.
- a further advantage is that a lower pressure is sufficient and the material and mold are thus less stressed.
- FIG. 1 uses a press mold to illustrate a method for connecting rigid contact bodies with flexible conductor pieces.
- FIG. 2 a method is illustrated on the basis of another mold, in which rigid contact bodies are produced from a semifinished product used for flexible conductor pieces.
- FIG. 3 shows the press mold according to FIG. 2 m in a top view after completion of the contact body and after removal of the press die.
- FIG. 4 illustrates the shaping of end parts of flexible conductors into a solid connection piece by means of another compression mold.
- FIG. 5 shows the press mold corresponding to FIG. 4 in ⁇ er
- the method illustrated in FIG. 1 is used to attach flexible conductor pieces 1 to a rigid contact body 2 made of copper, which in the example shown forms the movable contact bolt of a vacuum switching tube 3.
- the method is carried out by means of a press mold 4, to which a central full mandrel 5 belongs, which connects to the contact body 2 and continues its profile.
- the flexible conductor pieces 1 are preferably produced from a strand-shaped or rope-shaped semi-finished product made of copper, from which sections 8 of a suitable length are first divided. First partial lengths 9 of sections 8 are introduced through chamber 6 of die 4 through opening opening 6. With regard to the mechanical compression provided, the partial lengths 9 are dimensioned such that they can be laid around the contact body 2 in two layers. Since m the present example three flexible conductor pieces 1 for
- a tubular press die 12 e is now inserted into the press mold 5 and a pressing force is applied in the direction of an arrow 13.
- the pressing force is chosen so that the material of the rope or strand-shaped semi-finished product is stressed up to the yield point and thereby comes into intimate contact with the contact surface 11 of the contact body 12.
- the high pressing force results in a flat connection between the material of the semifinished product of the sections 9 and the contact body 2.
- the material of the sections 9 is compressed to the dimension shown to the right of the dash-dotted line 10.
- the total of six layers of the partial lengths 9 now have a somewhat lower height than that of the contact body 2.
- a second partial length 14 of the sections 8 forms the flexible conductor pieces 1.
- the method illustrated in FIG. 1 can also be used in the same way for differently designed contact bodies.
- this method can also be used to understand rigid contact bodies in the form of contact levers for low-voltage circuit breakers with flexible conductor stuck.
- an arrangement of the partial lengths of the semi-finished product lying in the plane of the contact lever is recommended if more than one flexible conductor piece is provided per contact lever.
- the connection between flexible conductor pieces 1 and a rigid contact body arises in that both parts are produced together.
- a mold 15 with a chamber 16 and an exit opening 17 leading the chamber is provided.
- a partial length 19 of a gate 18 of a semi-finished product of the type described, which is dimensioned in this way, is introduced into the chamber 16, its mass corresponds to the contact body to be manufactured.
- the press mold is provided with a mandrel 20.
- a press die 21 has a recess 22 corresponding to the mandrel 20.
- FIG. 2 is divided by a dash-dotted line 23 m, a left and a right part, the left part showing the state before the action of a pressing force according to an arrow 24 and the right part showing the state after the pressing operation has ended.
- FIG. 3 builds on the state according to the right part of FIG. 2 and shows the mold 15 m from the top view with the press die 21 removed and a finished contact body 25.
- This is designed as a contact lever of an air-switching low-voltage circuit breaker and has one by means of the mandrel 22 (FIG. 2) bearing opening 26. Due to the pressing pressure reaching to the yield point of the material of the semifinished product, the contact body 25 has a uniform, solid nature, such as that of a contact body stamped, for example, from sheet metal material.
- Remaining second partial lengths 27 of section 18 form the flexible conductor pieces 1, by means of which the contact body 25, which is pivotably mounted in a switching device, can be connected to a stationary conductor. Because the contact body 25 and the flexible conductor pieces 1 are manufactured in one piece without the use of heat, the flexibility of the semi-finished product used is fully retained.
- the pressing process explained with reference to FIG. 2 is also used to connect a contact pad 30 to the contact body 25.
- the contact pads 30 have a profiled extension 31 on their rear side for anchoring in the material of the semi-finished product of the partial lengths 19.
- the sections 18 of the semi-finished product can be dimensioned in such a way that a third part length 32 remains, which m ner further mold 33 according to Figure 4 to be formed into a connector 34.
- a press ram 35 m is pressed in the manner already described in the direction of an arrow 36 with a pressing force. It is advisable to ensure that the thickness of the connecting piece 34 corresponds approximately to the thickness of the non-compressed conductor pieces 1 by means of a double-layer arrangement of the partial lengths m of the compression mold.
- the semi-finished product to be processed can be treated with the flux in question before the m is introduced.
- a lower consumption of flux can, however, be achieved by introducing a suitably chosen dose of the flux together with the semi-finished product to be compressed m into the mold 4, 15, 33 or 37 that is used in each case.
- the flux When pressing, the flux first penetrates all the voids between the fine wires of the semi-finished product and is intensively touched with the material of the semi-finished product as the pressure increases. brings. If the transformation to a solid body has been carried out, excess flux is deposited on the outside and can therefore, for. B. in a water bath.
