Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) FIG. 1 shows a side view of a soldering tip fastening device, according to one or more embodiments of the invention, assembled to a soldering device.

(2) FIG. 2 shows an exploded perspective view representation of a soldering device as well as of a soldering tip fastening device according to one or more embodiments of the invention.

DETAILED DESCRIPTION

(3) FIG. 1 shows a soldering device 1. A soldering tip fastening device 2 is mounted on the soldering device 1. Due to the mounted state, not all components of the soldering tip fastening device 2 are visible; these will be explained later with reference to FIG. 2. The soldering tip fastening device 2 includes a soldering tip fastener 3. The soldering tip fastener 3 holds a soldering tip 4 at the soldering device 1 in the state shown in FIG. 1. The soldering tip fastening device 2 further includes a sleeve 5 having an elastic element 6. Both may facilitate holding the soldering tip 4. In the variant shown in FIG. 1, a shell 7 is additionally provided. It may comprise two half shells 7a and 7b as in the present embodiment. In the present embodiment, the shell 7 has a knurled outer circumference 8.

(4) In FIG. 2, further parts of the soldering device 1 are visible. The soldering device 1 has a heating element 9. The soldering tip 4 is brought in contact with the heating element 9 in order to heat the soldering tip 4. At the end of the heating element 9 facing the soldering tip 4, a temperature sensor 10 is provided. The temperature sensor 10 may facilitate an open-loop and/or closed-loop temperature control.

(5) FIG. 2 further shows components of the soldering tip fastening device 2 not visible in FIG. 1. A soldering device fastener 11 is visible. The soldering device fastener 11 can have a thread 12, which may be an internal thread or an external thread. Thread 12 may be screwed to a corresponding thread (not shown) on the soldering device 1 in order to connect the soldering tip fastening device 2 with a soldering device 1. The soldering device fastener 11 may have an engagement surface 13. The engagement surface 13 may be adapted for engagement with a tool, for example an open end wrench. The engagement surface 13 may be a multi-sided surface, e.g., square cut or hexagonal. Using a tool for screwing the soldering tip fastening device 2 to the soldering device 1 may serve the purpose of increasing and/or more accurately adjusting the associated tightening torque.

(6) In some embodiments, the thread 12, the engagement surface 13, the elastic element 6, and the sleeve 5 are inseparably connected with one another. Alternatively, each individual connection between these parts may also be provided in a separable manner. Particular preferred variants of inseparable connections are positive substance joints, especially welded connections.

(7) As shown better in FIG. 2, shell 7 may be implemented in a multipart way. The parts of the shell 7 are shown in the form of the first and second half shell 7a,7b, respectively. A complementary surface 14 is visible on the second half shell 7b. The complementary surface may be brought into complementary engagement with the engagement surface 13. A snap connector 15 is shown on the first half shell 7a. The half shells 7a and 7b may be interlocked using such a snap connector 15.

(8) In order to fasten the soldering tip 4 on the soldering device 1, the soldering tip 4 may be put onto the heating element 9. In this state, the soldering tip fastening device 2 may be put over the soldering tip 4 and the heating element 9. For secure fastening, the soldering tip fastening device 2 may be screwed to the soldering device 1 using the thread 12. By attaching the half shells 7a and 7b, a manual assembly is facilitated. By tightening as required, the tension of the elastic element 6 may be adjusted. Thereby, the contact pressure between the soldering tip 4 and the heating element 9 and/or the temperature sensor 10 may be adjusted as well. In the fastened state, the elastic element 6 may prevent an inadmissible increase of the contact pressure, which may be caused by thermal expansion of the components.

(9) The present invention may, of course, be carried out in other ways than those specifically set forth herein without departing from essential characteristics of the invention. The present embodiments are to be considered in all respects as illustrative and not restrictive, and all changes coming within the meaning and equivalency range of the appended claims are intended to be embraced therein.
