Definitions
- the invention is based on an overload protection for electrical machines according to the preamble of claim 1.
- An interference choke is often used for this purpose, which is designed in two parts and is soldered together at a connection point to be separated with a solder of a certain melting temperature, that is to say forms a solder point.
- a solder of a certain melting temperature that is to say forms a solder point.
- the windings of the interference choke exert a certain pretension on the interference choke and thus on the connection point, so that this connection should be separated when the solder point softens.
- the electrical circuit of the electrical machine should then be permanently interrupted and the electrical machine should be protected against destruction. Often, however, the pretension is not high enough so that the soldering point is not safely separated when the suppressor choke is heated.
- the overload protection according to the invention for electrical machines has the advantage over the fact that an electrical machine is protected from destruction or fire in a simple manner.
- connection lug is a coil spring.
- FIG. 1 shows an interference choke according to the prior art
- 2 shows a suppressor choke of an overload protection according to the invention arranged in a brush holder
- FIG. 3 shows a partial section of an overload protection according to the invention.
- Figure 1 shows an interference choke according to the prior art, which is designed in two parts, and consists of a first part 2 and a second part 4.
- the first part 2 and the second part 4 are connected to a solder at a separation point 7.
- the solder melts at a certain temperature. Depending on the application, the solder is selected according to its melting temperature.
- the interference choke also has a first electrical connection element 5 and a second electrical one
- Connection element 6 for an electrical connection in an electrical circuit.
- FIG. 2 shows the interference choke 1 of an overload protection according to the invention in the partially installed state in a brush holder 9.
- the first connection element 5 is connected to a first electrical connection lug 11 which is integrated in the brush holder 9.
- the connection lug 11 forms the connection to the electrical circuit of an electrical machine.
- the first connection lug 11 does not, for example, exert any mechanical tension on the first connection element 5 and its connection point.
- the second connection element 6 of the interference choke 1 is also connected electrically and mechanically to a second electrical connection lug 13.
- the second connecting lug 13 is connected to a further electrical line in the brush holder 9.
- the free end 14 of the second connection lug 13 must be moved in the direction of the second connection element 6 with the application of a force so that it can be attached to the second connection element 6.
- FIG. 3 shows how the second connection lug 13 is connected to the second connection element 6.
- connection lug 13 is bent in the direction (parallel to 18) of the second connecting element 6 with the application of a mechanical force, the connection being established, for example, by soldering while maintaining the force .
- the connection point 15 has been established, for example after the solder has cooled, the force on the second connecting lug 13 can be reduced.
- the second connecting lug 13 then exerts a mechanical tension in the axial direction 18 on the connection point 15.
- both connection lugs 11, 13 can be used to exert a mechanical tension on the respective connection points 15.
- the connection lugs 11, 13 can also be coil springs.
- connection point 15 of the connection lugs 11, 13 and connection element 5, 6 takes over the function of the separation point 7 of the interference choke according to the prior art.
- This separation point 7 is omitted in the overload protection according to the invention. Instead, a connection point 15 is used, which is also present in the prior art.
- This separation point 7 projecting beyond the dimensions of the interference choke often causes a short to ground in the pole housing when the connection point 7 is separated. This disadvantage does not apply to the overload protection according to the invention.
- connection points of connection lugs and connection elements both can also be designed as connection points to be separated in the event of an overload.
