Definitions
- the invention relates to a method for fastening a flat plug in the base of an electrical component, for example a relay, which is made of insulating material, the flat plug being inserted through an opening in the flat base until it is at least one integrally formed shoulder on a first The surface of the base base is supported, and is then clamped to the opposite second surface of the base base by means of at least one projection formed from the plug.
- an electrical component for example a relay, which is made of insulating material
- the flat plug being inserted through an opening in the flat base until it is at least one integrally formed shoulder on a first
- the surface of the base base is supported, and is then clamped to the opposite second surface of the base base by means of at least one projection formed from the plug.
- the invention relates to a base produced according to this and the use of such a base in an electromagnetic relay.
- Such a fastening of a flat plug can be seen, for example, from EP-A-0 281 950.
- the flat plugs are each provided with obliquely flared locking tabs which yield somewhat resiliently when the plug is pushed through the base and then brace on the underside of the base in the manner of barbs.
- Such fastening tabs set up against the direction of insertion can also be pressed out of the plug material after insertion.
- Such a latching does not always result in a sufficiently stable tight fit, while the possibility of attacking tools is unfavorable for subsequent pressing out. Tension can also be caused in this case.
- This type of attachment also requires elasticity of the base plastic; brittle plastics are unsuitable for this.
- the plug elements In the case of such flat plugs, it is also customary for the plug elements to be jagged after they have been inserted, in each case to the Narrow sides of the connector notches are hammered in and the notched notches are pressed outwards. Even with this method, a reliable tight fit cannot always be achieved, particularly when strong forces occur counter to the direction of insertion. In addition, the notching causes tension in the opening in the base, as a result of which plastic material easily breaks out, particularly on the edges of the opening.
- the known methods lead to deformation or even tearing of the plastic material at the base edge, or at least because of the plastic's evasion, there is none good tightness achievable for the connector.
- the aim of the invention is to provide a method for fastening a flat plug in the base of an electrical component, as mentioned at the beginning, with which a reliable tight fit of the respective flat plug in the base can be ensured in a relatively simple manner in terms of production technology.
- the term “flat connector” is generally understood to mean a connection element consisting of flat sheet metal.
- a preferred application are the flat plugs or Faston plugs used for plug connections in relays and the like, but the invention can also be used for flat connecting elements which are intended for other types of contacting, such as soldering and the like, for which purpose they can be cut into any shape at the ends, for example.
- At least one rib which is elongated in the direction of insertion is embossed from at least one of the two flat sides of the plug before being inserted into the base, and which is at least partially beyond the opening after insertion, and b) the part of the rib protruding from the opening is peeled off from its distal end in the direction of the base from the plug body and deformed towards the second surface of the base base.
- a rib previously embossed from the sheet metal material is deformed in a combined peeling and upsetting process against the direction of insertion and is braced against the second surface of the base base, that is to say against the underside of the base.
- the peeling process does not result in compression or tension in the opening itself, as in previous methods, but rather the part of the rib lying outside the opening is lifted off in the form of a chip and compressed and bent towards the underside of the base.
- a retaining lug is formed which reaches over the edge of the opening and forms a secure form fit with the underside of the base.
- a particularly advantageous embodiment of the method provides that the rib is provided at its distal end with a projection over its remaining part, in particular over the part lying in the area of the base edge.
- the rib has a step-like shape with an embossed nose or a thickening at the distal end. Then there is a particularly favorable peeling with unwinding of the peeled material to the outside, since the peeling tool with the protruding nose grips a large contact surface, while the rib tapering towards the base can be peeled off easily, without a strong compression deformation in the area of the socket opening acts in there, which could lead to the mentioned tension.
- a base obtained according to the invention with one or more flat plugs is characterized according to the invention in that at least one holding lug protruding from a flat side of the plug and bent against the direction of insertion rests on the second surface of the base base.
- the opening in the base corresponds in each case to the cross section of the inserted flat plug and has guide channels for the embossed ribs on its side walls.
- additional sealing lugs are preferably stamped on it, which seal the full cross section of the guide channels.
- FIG. 1 shows a schematically illustrated relay base with a flat plug to be inserted in a perspective representation
- FIGS. 2 and 3 each show a detail view of the flat plug inserted in the base, in section and in plan view,
- FIG. 1 shows a schematic relay base 1, the base base 2 of which has several openings 3 for receiving flat cores 4 (only one shown).
- additional support ribs 5 can be integrally formed on the side of the openings in order to increase the insertion length for the flat connector 4 and thus to increase the stability.
- the flat connector 4 can be cut and bent at the top; it is used, for example, for welding contact elements or wires to conduct contact or coil current.
- this plug 4 has one or two shoulders 6 with which it is supported on the first side, ie the top of the base base 2, after it has been inserted into the base 1.
- the flat plug in the present case has two ribs 7 which are embossed on a flat side and extend in the plugging direction. At their distal ends 7a, ie at the ends directed towards the free plug end 4a, they have a step-like raised nose 8. To insert the ribs 7, guide channels 9 are formed in the side walls of the openings 3, the depth of which corresponds to the height of the lugs 8 .
- the flat connector 4 can be inserted with its end 4a into an associated opening 3 during assembly until the shoulders 6 stand on the base base 2 and the lugs 8 and part of the ribs 7 protrude on the underside of the base.
- FIGS. 2 and 3 show the state after the flat plug 4 has been plugged into the base 2 of the socket.
- the rib 7 is the material of the flat plug 4 approximately over half the thickness - shaped.
- a height of the rib of roughly approximately half the material thickness has proven to be expedient, with the nose being additionally shaped accordingly.
- deviating conditions are also conceivable, in particular with other dimensions of the plug material.
- the guide channel 9 must be correspondingly deep for the nose 8 to be pushed through, there remains between the remaining ribs pe 7 and the wall of the channel 9, an air gap 10.
- a sealing nose 11 is formed at the rear end 7b of the rib, the height of which corresponds to that of the nose 8, so that the cross section of the guide channel 9 is filled.
- Figure 3 shows the inserted flat connector 4 in plan view.
- the guide channels 9 of the opening 3 and the flat plug 4 with the ribs 7 stamped out on one side can be seen.
- a rib 7 1 could also be stamped out on the other side and inserted into a guide channel 9 ' become.
- the fixation of the tab connector is shown in Figure 4.
- the flat plug 4 is seated with a shoulder 6 on the upper side 2a of the base base 2 after it has been inserted into the base in the direction of the arrow 12.
- the flat connector is supported on its upper edge 4b by a counter support 13.
- this nose 8 with the subsequent part of the rib 7 is now peeled off from the tab 4, compressed and bent outwards.
- the material deformation creates a retaining lug 17 which bears against the underside 2b of the base base 2, its direction of action being indicated by the arrow 18. Due to the air gap 10 there is practically no tension and no side pressure in the opening, but the tab is fixed in a form-fitting manner on the base by the retaining lug 17.
