Abstract

An electrical protective device is described which has two PTC thermistor components which are in the form of plates and are arranged in a common housing. The housing in each case has an opening on two opposite sides, which opening corresponds to the dimensions of the PTC thermistor components such that the PTC thermistor components can be inserted into the housing through the openings. The two PTC thermistor components are electrically isolated from one another in the housing. The PTC thermistor components each have at least two connecting wires, by means of which the PTC thermistor components are locked to the housing.

Claims (31)

1. An electrical protective device, comprising:

two PTC thermistor components in the form of plates;

a common housing; and

at least two connecting wires;

wherein the PTC thermistor components are arranged in the common housing;

wherein the housing has an opening on each of two opposite sides;

wherein the openings have a size that corresponds to dimensions of the PTC thermistor components such that the PTC thermistor components can be inserted into the housing through the openings;

wherein the PTC thermistor components are electrically isolated from one another in the housing; and

wherein the PTC thermistor components are locked to the housing by the connecting wires.

2. The protective device according to claim 1 , wherein the housing is a one-piece housing.

3. The protective device according to claim 1 , wherein the housing comprises plastic.

4. The protective device according to claim 1 , wherein external dimensions of the housing project only a few millimeters beyond the dimensions of the PTC thermistor components.

5. The protective device according to claim 1 , wherein the PTC thermistor components make contact with connecting wires on two opposite base surfaces.

6. The protective device according to claim 1 , wherein the two connecting wires arranged parallel to end faces on opposite end faces of the thermistor component, wherein the connecting wires are arranged offset through 90° with respect to one another.

7. The protective device according to claim 6 , wherein the connecting wires are angled through 135° in a central area and parallel to the end surfaces of the PTC thermistor components.

8. The protective device according to claim 6 , wherein the connecting wires of the PTC thermistor components are bent through 90° at their ends.

9. The protective device according to claim 8 , wherein the ends of the connecting wires which are bent through 90° are used for locking the PTC thermistor components to the housing.

10. The protective device according to claim 1 , wherein the housing has a plurality of cutouts on its lower face.

11. The protective device according to claim 10 , wherein the cutouts hold the connecting wires of the PTC thermistor components.

12. The protective device according to claim 1 , wherein the PTC thermistor components are mounted in the openings in the housing by clamping.

13. The protective device according to claim 1 , wherein the openings in the housing have clamping ribs.

14. The protective device according to claim 1 , wherein the openings in the housing have a conical attachment in an outer area.

15. The protective device according to claim 1 , wherein the PTC thermistor components have a rectangular base surface.

16. The protective device according to claim 1 , wherein the PTC thermistor components have a round base surface.

17. The protective device according to claim 1 , wherein the protective device suitable for use in a telecommunications device.

18. An electrical protective device, comprising:

a housing having a first opening at one side of the housing and a second opening at an opposite side of the housing;

first and second PTC thermistor components arranged in the housing, dimensions of each PTC thermistor component corresponding to the size of a corresponding opening such that the PTC thermistor components can be inserted into the housing through the openings, wherein the PTC thermistor components are electrically isolated from one another in the housing;

a first connecting wire arranged adjacent the first opening and a second connecting wire arranged adjacent the second opening, the PTC thermistor components being locked to the housing by the connecting wires.

19. The protective device according to claim 18 , wherein the connecting wires are each arranged parallel to an end face of a corresponding PTC thermistor component, the first connecting wire being arranged offset through 90° with respect to the second connecting wire.

20. The protective device according to claim 19 , wherein each connecting wire is angled through 135° in a central area.
