Definitions

• the invention relates to a soldering tool mentioned in the preamble of claim 1.
• soldering tools in which the soldering tip is fixed with the aid of a fastening sleeve on the heating element or on the handle, it is provided in most cases that the soldering tip is pushed through the inside of the fastening sleeve or this fastening sleeve engages over the soldering tip and with one Fastening bead cooperates on the soldering tip in order to clamp it against a tubular or rod-shaped heating element.
• the fastening sleeve itself is fastened to the front end of the handle or to the rear end of the heating element using a type of union nut or the like.
• soldering tips can be used, for example, a soldering tip with a curved free end cannot be pushed through the fastening sleeve. Furthermore, only soldering tips with a predetermined diameter can be used for given dimensions of the fastening sleeve.
• the invention has for its object to provide a soldering tool of the type mentioned, in which soldering tips of any shape and external dimensions can be used despite the use of a fastening sleeve.
• the rotary engagement devices can be designed in the manner of a bayonet lock and include locking projections and locking grooves on the parts to be fastened to one another.
• the soldering tip can both be inserted into the free end of the fastening sleeve and also overlap it, the engagement devices of the fastening sleeve being correspondingly arranged on the inner circumference or on the outer circumference thereof.
• the latching groove in each case has an axially extending section and a circumferentially extending section which, starting from the axial section, is directed in such a direction that, when the fastening sleeve is tightened, an engagement of the latching projection in the circumferentially extending section the groove results.
• the latching groove can be formed on the soldering tip, in which case the fastening sleeve carries the latching projection, or the latching groove can be formed on the fastening sleeve while the soldering tip carries the latching projection.
• diametrically opposed locking grooves and locking projections are provided on the two parts to be connected.
• a different number of locking projections or locking grooves is also possible.
• FIG. 1 is a partially sectioned view of a soldering tool with an embodiment of the mounting sleeve or de soldering tip
• Fig. 2 is a perspective view of the free end of the mounting sleeve and the cooperating with it
• FIG. 3 is a partially sectioned view of the embodiment of the fastening sleeve
• Fig. 4 is a partial view of the mounting portion of the and 5 mounting sleeve, Fig. 4 is a side view
• Fig. 5 is a top plan view of the
• Fig. 6 is a partially sectioned side view of a
• Fig. 7 is a view of the rear end of the soldering tip, which shows the locking groove more clearly.
• Fig. 1 an embodiment of the soldering tool is shown with a front end of the handle (10) only partially shown, on which an ⁇ tab- or tubular heating element (11) is attached, on the front end of which a soldering tip (4) is pushed.
• the soldering tip (4) is fixed to the handle (10) or the radiator (11) with the aid of a fastening sleeve (1), the fastening sleeve using a union nut (8) on a fastening part of the handle or an external thread (12) the radiator (11.) is attached.
• Rotary engagement devices are formed, which will be explained in more detail below and which are brought into engagement with one another in the event of a relative rotation between the soldering tip (4) and the fastening sleeve (1).
• This relative rotation which leads to a locking of the parts with one another, preferably takes place in the fastening direction of the fastening sleeve (1), that is to say in a direction in which the union nut is tightened on the external thread (12).
• the fastening sleeve (1) has at its free end locking projections (2) which are formed on a locking sleeve (3), the locking projections (2 ) diametrically opposite inside the free end of the locking sleeve (3). extend.
• the soldering tip (4) has a locking groove (5) which, according to FIG. 7, has a section (5b) which extends in the axial direction and a section which extends in the circumferential direction.
• Has section (5a) which starts from the axially extending section (5b) and extends in the direction of the tightening rotation of the fastening sleeve (1), which is indicated by the arrow (13) in Fig. 2.
• the rotary engagement devices recognizable in FIG. 2 could also be designed in the opposite way, that is to say the locking sleeve (3) could have a locking groove, while the soldering tip (4) has locking projections cooperating therewith.
• the mounting sleeve (1) is shown individually to To make details more clearly recognizable.
• the fastening sleeve (1) by means of a flange in the union nut (8) is rotatable, but rigidly fastened in the axial direction and carries on its side facing the soldering tip an attached locking sleeve, which can be manufactured separately and is provided with two tabs in the form of tabs (2) bent into the interior of the fastening sleeve (1).
• This locking sleeve is shown individually in FIGS. 4 and 5.
• the separate production of the locking sleeve (3) and the fastening sleeve (1) enables simplified production.
• soldering tip (4) which can have both a straight tip (shown with solid lines) and a bent tip (shown with dash-dotted lines).
• the soldering tip (4) has an inner bore (14) for receiving the free end of the radiator (11) and it is provided at its rear end with the locking groove (5) already mentioned, which according to FIG. 7 has a section which extends in the circumferential direction (5a) or a section (5b) extending in the axial direction, which merge into one another.
• Fastening sleeve (1) engages over or inserted into this, there are no restrictions with regard to the shape and dimensions of the soldering tip due to the shape and dimensions of the mounting sleeve, so that the described mounting sleeve can be used with a variety of shapes and dimensions of soldering tips.
