Abstract

Claims (34)

1. A soldering tip fastening device for releasable attachment to a soldering device, the soldering device having a heating element, the soldering tip fastening device comprising:

a soldering device fastener configured to fasten the soldering tip fastening device on the soldering device;

a soldering tip fastener comprising a sleeve and an elastic element; the soldering tip fastener configured to releasably fasten a soldering tip on the soldering device by sliding the sleeve longitudinally over both the heating element and the soldering tip, and tightening the soldering device fastener on the soldering device;

wherein the soldering tip fastener and the soldering device fastener form opposite ends of the soldering tip fastening device, and wherein the soldering device fastener and the sleeve are longitudinally collinear;

wherein the sleeve and the soldering device fastener are interconnected by the elastic element with the elastic element interposed between and longitudinally separating all of the sleeve from all of the soldering device fastener, the sleeve being configured such that the elastic element is tensioned during the fastening of the soldering tip on the soldering device by the soldering tip fastening device;

wherein the sleeve is configured to releasably abut the soldering tip to press the soldering tip longitudinally toward the soldering device with the soldering tip releasably held by the sleeve in a fixed position relative to the sleeve and the sleeve peripherally surrounding the heating element of the soldering device.

2. The soldering tip fastening device of claim 1 , wherein a tension of the elastic element is adjustable by rotating the soldering device fastener.

3. The soldering tip fastening device of claim 1 , wherein the soldering device fastener comprises a thread configured to fasten the soldering tip fastening device on the soldering device.

4. The soldering tip fastening device of claim 3 , wherein the elastic element and the thread are connected to one another in an inseparable manner.

5. The soldering tip fastening device of claim 4 , wherein the elastic element and the thread are connected to one another in an inseparable manner by a welded connection.

6. The soldering tip fastening device of claim 1 , wherein the soldering device fastener has an engagement surface.

7. The soldering tip fastening device of claim 6 , wherein the elastic element and the engagement surface are connected to one another in an inseparable manner.

8. The soldering tip fastening device of claim 7 , wherein the elastic element and the engagement surface are connected to one another in an inseparable manner by a welded connection.

9. The soldering tip fastening device of claim 1 :

wherein the soldering device fastener comprises an engagement surface disposed longitudinally opposite the sleeve relative to the elastic element;

wherein the soldering tip fastening device further comprises a shell having a complementary surface which is configured for complementary engagement with the engagement surface of the soldering device fastener, the shell comprising two interlockable half-shells.

10. The soldering tip fastening device of claim 9 , wherein the shell includes an integral hinge.

11. The soldering tip fastening device of claim 9 , wherein the shell has a snap connector.

12. The soldering tip fastening device of claim 9 , wherein the shell has a knurled outer circumference.

13. The soldering tip fastening device of claim 1 , wherein the elastic element is a coil spring.

14. The soldering tip fastening device of claim 1 , wherein the elastic element and the sleeve are connected to one another in an inseparable manner.

15. The soldering tip fastening device of claim 14 , wherein the elastic element and the sleeve are connected to one another in an inseparable manner by a welded connection.

16. A soldering device, comprising:

an axially extending heating element;

a soldering tip fastening device configured to releasably attached to the soldering device; the soldering tip fastening device comprising:

a soldering device fastener configured to fasten the soldering tip fastening device on the soldering device;

a soldering tip fastener comprising a sleeve and an elastic element; the soldering tip fastener configured to releasably fasten a soldering tip on the soldering device by sliding the sleeve longitudinally over both the heating element and the soldering tip, and tightening the soldering device fastener on the soldering device;

wherein the soldering tip fastener and the soldering device fastener form opposite ends of the soldering tip fastening device;

wherein the sleeve and the soldering device fastener are interconnected by the elastic element with the elastic element interposed between and longitudinally separating all of the sleeve from all of the soldering device fastener; the sleeve being configured such that the elastic element is tensioned during the fastening of the soldering tip on the soldering device by the soldering tip fastening device;

wherein the sleeve is configured to releasably abut the soldering tip to press the soldering tip longitudinally toward the soldering device with the soldering tip releasably held by the sleeve in a fixed position relative to the sleeve and the sleeve peripherally surrounding the heating element of the soldering device, with the heating element and the soldering tip being longitudinally collinear.

17. The soldering device of claim 16 , wherein a tension of the elastic element is adjustable by rotating the soldering device fastener.

18. The soldering device of claim 16 :

wherein the soldering device fastener has an engagement surface disposed longitudinally opposite the sleeve relative to the elastic element;

wherein the soldering tip fastening device further comprises a shell having a complementary surface which is adapted for complementary engagement with the engagement surface of the soldering device fastener, the shell comprising two interlockable half-shells.
