Definitions
- a relay of the type mentioned is in WO 94/22156 described.
- a Cap placed over the bobbin is with the base Formation of a closed housing connected.
- This well-known Structure is designed for conventional solder connection technology; for stronger mechanical or thermal loads is the connection structure of the base and the bobbin not designed.
- the aim of the present invention is to build a relay of the type mentioned at the outset in such a way that the insulation strength between the magnetic circuit and the winding improved and at the same time the mechanical stability of the relay if possible small volume is increased; different should Connection techniques, in particular also SMT connections and press-in handles can be used without changing the other construction be.
- this goal is achieved with the relay structure mentioned achieved in that a basic body by all sides Wrapping the coil with insulating material is formed, which together forms a cuboid housing with the base, the Coil together with the core in the upper area of the base body embedded and isolated at the bottom by a partition and with the base body molded all around downwards Has side walls that enclose the base in a chess-like shape and form a closed control room with it.
- a basic body produced by extrusion-coating the coil with insulating material the rigidity and stability of the Relay construction. The adjustments made during production are safely maintained in this way, even if by mechanical or thermal loads on the outside The main body and base act on the relay housing.
- This stable structure then has a particularly advantageous effect out if the body has a paragraph on either side of the anchor has, under which are each arranged in a row Contact pins are located and if necessary as Support area for these pins is suitable.
- solder pins from one in the base injected printed circuit board are bent down.
- the stable structure according to the invention is effective then when connecting pins are used, which differ from the Base vertically up to the respective support area extend the body.
- the connection pins each in grooves of the base body are arranged in the support area and there by means of curable Potting compound to be fixed. So it is possible that after installing the anchor on the base and making the precise adjustment of the contact spacing of the base body pushed onto the base with the magnet system until the armature lies exactly against the magnet system or has reached the specified air gaps to the yokes.
- the Base body By pouring adhesive or potting compound, the Base body to be sealingly connected to the base, wherein the pins in the aforementioned grooves in a previous or cast and fixed at the same time become.
- the polarized relay shown in Figures 1 to 3 essentially has two assemblies, namely a base body 1, which contains a magnet system, and a base 2 with an anchor and a contact arrangement.
- the basic body 1 has essentially a cuboid shape on the outside, due to the extrusion coating of the magnet system is formed.
- This magnet system contains a coil consisting of a coil body 3 and a winding 4.
- a coil-shaped core 5 is arranged on the coil former.
- the ends of the respective protruding from the coil body 3 Kerns 5 are coupled to two yokes 6 and 7, which in the case of; game of Figures 1 to 3 also in the material of the Base body 1 are embedded.
- the bobbin has recesses made of the material of the Base body 1 are filled, so this is production-related interruptions of this coil form; but it could also be a conventional bobbin with a continuous insulating tube as winding support be used. In any case, however, encloses the plastic material of the base body 1, the coil winding at all Sides, so that good insulation from the metal parts of the magnetic circuit and - by a partition 18 on the Underside of the coil - especially opposite the contact elements is guaranteed.
- the magnet system also contains a permanent magnet 8 shown in Figure 1, the three-pole magnetized and is inserted between the two yokes 6 and 7 is that its two end poles of the same name (N) each are coupled to one of the yokes 6 and 7. In this For example, the permanent magnet with crush ribs 9 of the base body be attached. But there are also other mounting options conceivable.
- the base body 1 also has molded on the underside, all-round side walls 11 with which the Base body 1 can be plugged onto the base 2. Reach around the side walls 11 form the base 2 box-shaped a closed between the magnet system and the base Control room 10. Also are inside the main body 1 two longitudinal webs 12 parallel to the coil axis or provided the long sides of the base body. These form together with the parallel side walls 11 each have a longitudinal groove 13 with a support surface 14 on its top, the-at Need - to support and stabilize the still serve descriptive contact connections.
- center contact springs 24 are in a known manner with a Anchor 25 connected, also via the bearing strips 23 in is known to be kept in storage.
- connections 21 and 22 each have the top of the base projecting support portions 21a and 22a, respectively when placing the base body 1 on the base 2 in the groove 13 between the respective side wall 11 and the respective Longitudinal web 12 come to rest.
- these grooves 13 each after assembly with potting compound to fill the connecting elements after curing reliably stabilized and supported.
- For the rest is the structure of the relay, apart from the new basic shape, in terms of function largely similar to that Relay according to WO 94/22156 mentioned at the outset, so that thereupon is not to be discussed further.
- FIG. 4 and 5 are in the same representation as seen in Figure 2 modifications of the main body. So FIG. 4 shows an embodiment in which the permanent magnet 8 already in the manufacture of the base body 1 with the yokes 6 and 7 is embedded.
- FIG. 5 shows another embodiment, in which the embedding of the base body 1 only the coil with bobbin 3 and winding 4 and the Core 5 includes, while special pockets for the yokes 16 and 17 are recessed, into which they are subsequently inserted can be.
- the permanent magnet 8 is also in this Case, as already shown with reference to Figure 2, retrospectively inserted and fixed by crush ribs 9.
- connection 21 and 22 depending on the type of used Connection technology can be varied.
- press-in handles with high press-in pressure be pressed into contact holes in a printed circuit board and thereby result in a solderless connection.
- support of the support sections 21a and 22a in Basic body particularly important, because in this way over the Base body transfer the press-in forces to the connections can be.
- the relay structure is also for other connection technologies applicable. So instead of the press handles shown also normal solder pins or laterally bent SMT connection lugs are provided. In these cases the support in the base body is not required to the same extent. It can be used to stabilize the overall structure be provided anyway. It is in the case of these connection techniques but also possible that shown in Figure 1 To make support sections 21a and 22a shorter or omitted allow.
- the coil connecting pins anchored in the base body 15 are always in accordance with the contact connection elements educated.
