Definitions
- the invention relates to an electromagnetic relay with the following features:
- a bobbin carries a winding between two coil flanges made of insulating material and further magnetic circuit parts;
- coil connection elements and contact connection elements are anchored in plug-in shafts standing perpendicular to the base plane.
- Such relays are known in many configurations, for example from EP-A-0 281 950.
- the problem with such relays is to connect the coil and the base including the functional parts of the relay attached to them as well and as simply as possible.
- contact elements can be fastened in the base or in the coil body by plugging in, which also enables automated assembly without further ado.
- a possibility is already given to a.
- Contact element form an additional holding arm to form the rinsing body on the base. Otherwise, the connection of the coil and base is essentially secured by welded-on winding connections and finally by a housing cap.
- Relays are also known, in which winding support points anchored in the coil flanges are simultaneously provided with integrally formed connecting elements which can optionally also be inserted through recesses in a base.
- the aim of the invention is to improve the connection of the bobbin and base in a relay of the type mentioned, with as few individual parts as possible enabling automated assembly, ropes.
- the connection elements should be designed in such a way that the winding ends of the winding ends can be wound easily and without additional winding elements, the electrical ones. Circuit of the coil rope as few connection points as possible.
- a method for producing a cer-like relay is to be specified. According to the invention, this aim is achieved with a relay of the type mentioned at the outset, which has the following additional features:
- At least one of the coil flanges has at least one plug-in channel parallel to the coil axis for a fastening leg, which is integrally formed on a coil connecting element;
- the coil connection elements each have hook-shaped mounting legs which are parallel to the coil axis and oamit to the base plane and which engage in corresponding plug-in channels on at least one coil flange, but expediently, however, on both coil flanges.
- the coil connection elements By anchoring the coil connection elements in the base, the coil body is thus held in a form-fitting manner on the base. Since these fastening legs also have molded-on winding pieces, which of course protrude from the respective plug-in channel, no additional winding support points are required for winding the winding ends; in the coil circuit, there is also no need for additional electrical connection points.
- An expedient method for producing a relay according to the invention is that the coil connection elements are first inserted with their fastening legs into a corresponding plug-in channel of a coil flange, that the winding is then applied to the coil body and the winding ends are each connected to a winding piece of a connection element and that finally the coil is connected to the base, the coil connecting elements being anchored in plug-in shafts of the base.
- the Eefestiguncsschenkel each from the outside of the winding facing away from a coil flange in direction on the winding inserted into the flange, the winding pieces each lying outside the plug-in channel.
- the fastening legs and the associated plug-in channels are each designed so that they can be fixed both in an intermediate position and in an end position, the respective winding piece being closer to the winding in the end position than when the intermediate position is taken.
- the fastening legs are only inserted up to the intermediate position into the plug-in channels of the respective coil flange before the winding is applied, and that after winding, but before mounting the coil former on the base, they continue into the plug-in channels until Reaching their end position. This results in additional strain relief for the winding ends.
- the winding pieces and / or the connecting elements themselves protrude into the winding area in their end position, while they are still outside in the intermediate position mentioned.
- formings for example embossings, can be provided which ensure sufficient stability between the connecting element and the coil former during winding.
- each coil connecting element has in each case a fastening section lying parallel to the base plane of the base, with the one or more horizontal fastening legs, from each of which a flat plug is bent vertically downward.
- the flat plugs are used not only to anchor the coil or the coil assembly in the base, but also for the direct plug connection of both winding ends in a mounting base.
- the contact is made from the respective attachment piece to the plug-in contact via the one-piece coil connecting element, without any connecting parts in the form of a welding point or a solder joint being located therebetween.
- this holding pin does not have a flat plug or connecting pin, but only serves to connect the coil body and base, while the electrical current path goes directly from the fastening section to a component connected to it and only from there to a flat plug (or else anchored in the base) Solder connection) is performed.
- FIG. 1 shows a coil body for a relay according to the invention and two associated coil connection elements in an exploded view
- FIG. 2 shows the coil body from FIG. 1 with winding and with inserted coil connection elements
- FIG. 3 shows the coil former from FIG. 2 mounted on a base in a sectional view
- Figure 4 shows a detail from Figure 2 with a modified embodiment of a connecting element.
- FIG. 1 to 3 does not show a complete relay, but only parts essential for the invention, such as coil cores, screws and coil connection elements, are shown in more detail.
- the missing parts of the relay like anchors,
- the yoke and contact elements, if not shown in FIG. 3, can be designed in the same way as, for example, in the case of a relay according to DE-A-34 26 595 or EP-A-0 281 950.
- the figures show a coil body 1 made of insulating material, the hollow of which Coil tube is used to hold a core, not shown.
- the coil former 1 has a flange 11 and 12 at each end.
- the fully wound and equipped coil former is placed on a base 2 (FIG. 3), which is also made of insulating material.
- each coil flange has plug-in channels which run parallel to the coil axis or parallel to the base plane of the relay.
- the coil flange 11 has a laterally open plug-in channel 13 and a closed plug-in channel 14 and also a non-visible plug-in channel 15.
- In the coil flange 12 is a laterally open
- Plug-in channel 16 is provided next to a closed plug-in channel 17.
- the coil connecting element 3 forms a flat plug 31, which is perpendicular in the normal installation position, and a fastening part 32 bent at right angles on the upper side.
- three fastening legs 33, 34 and 35 are cut free, which are inserted horizontally into the corresponding plug-in channels 13, 14 and 15 (not visible ) serve.
- a winding piece 36 is formed on the side, which, even when the fastening legs 33, 34 and 35 are inserted into the corresponding plug-in channels of the coil flange 11, remains outside of the plug-in channel 13 and is thus suitable for winding on a WichHunosende.
- Embossments 38 are formed on the fastening legs 34 and 35 and are used for temporarily fixing the respective fastening leg in the associated plug-in channel.
- connection element 3 In a similar manner to that of the connection element 3, a vertical flat plug 41 and a fastening part 42 bent at right angles to it are also formed in the coil connection element 4.
- Fastening legs 43 and 44 are in turn formed on this fastening part, which can be inserted into corresponding plug-in channels 16 and 17 of the bobbin flange 12.
- a winding piece 46 is formed on the side, which always protrudes laterally out of the open plug-in channel 16 even when it is inserted into the coil former, in order to serve for winding a winding end.
- a retaining web 47 with a clamping slot 47a for fastening and contacting an additional component is formed on the fastening leg 43.
- An embossing 48 corresponding to the embossing 38 is also formed in each of the fastening legs 43 and 44.
- the coil connecting elements 3 and 4 are inserted into the bobbin 1, and the fastening legs 33, 34 and 35 are inserted into the plug-in channels 13, 14 and 15 up to an intermediate position in which the respective fastening legs and the flat plug 31 are not yet over the Project the inner wall of the coil flange 11 facing the winding area.
- the coil connecting element 4 with its fastening legs 43 and 44 is inserted into the coil flange 12 up to a corresponding intermediate position. In this intermediate position, the respective fastening legs are temporarily locked by the embossments 38 and 46.
- the winding 10 is applied, the winding ends 10a and 10c ar being appropriately wound and soldered or welded to the corresponding winding pieces 36 and 46, respectively.
- the coil connection elements 3 and 4 are pushed inwards to the winding space up to their end position.
- the embossments 38 and 48 come out of the area of the plug-in channels 13, 14, 15 or 16 and 17, so that the parts are easily movable again. This means that they can be adapted to the specified spacing when they are subsequently plugged into the socket slots of the base.
- the coil connection elements By pushing the coil connection elements into their end position, the winding ends 10a and 10b of the coil wire are relieved of the tensile stress created during winding.
- Figure 2 shows this state.
- FIGS. 1 to 3 show an application example in which the winding ends are led out of the relay directly via the two coil connection elements 3 and 4 and their tabs 31 and 41, respectively. In this case, it is already possible to connect a component, such as a resistor or a diode, parallel to the coil between the two connection elements, which is done via the holding webs 37 and 47 described.
- a component such as a resistor or a diode
- FIG. 4 shows a section of the coil flange 11 from FIG. 2.
- the coil connection element 3 is replaced by a modified connection element 130, which, however, as in the case described above, has a fastening section 132 with fastening legs 133 and 134 and with these in the plug-in channels 13 and 14 the coil flange 11 is attached.
- the corresponding winding end is fastened to the winding piece 136, and the holding web 137 with the clamping slot 137a serves to clamp a connecting wire for the component mentioned.
- the coil connection element 130 does not have a flat plug, but only a holding pin formed vertically downwards, the length of which extends only far enough into the base and to the underside thereof, that an anchoring, for example by notching, in the base is possible.
- the current path thus leads from the winding end in question via the coil connection element 130 and the holding web 137 to the component (not shown), the end of the component opposite the holding web 137 being connected in a suitable manner to a separate connector plug (not shown) (or a soldering pin), which is anchored on its side, electrically separate from the coil connection element 130, in the base or in the coil body.
