3 CLOSURE HEAD FOR A BALLOON

The invention relates to a closure head for the elastically expandable

Balloon neck of a balloon, with a cup-shaped housing which has a &igr;

open end and one end closed by a base and with ;

sealing its open end by elastic expansion of the balloon neck |

can be inserted into it, and one arranged in the open end of the housing |

net light reflector, which surrounds a lamp holder that has two I

electrical cables that are sealed and lead out through the housing base |

are provided with a g located on or near the outside of the housing bottom

f electromechanical coupling for electrical connection of the lamp *

socket is connected to an external power source, i<

Such a locking head is known from DE-GM 85 22 395. There is )

The electromechanical coupling is designed as a lamp screw base. This j

However, in addition to the metal screw sleeve of the screw base, it requires a * separate fastening of the wire ends of the cables to the screw sleeve.

In contrast , the invention solves the problem of providing a closure |

head of the type mentioned above in such a way that the manufacturing and |

Assembly effort for the locking head is reduced. I

&iacgr; This is achieved according to the invention in that the electromechanical $

Coupling is designed as a plug-in socket through which the cables axially |

which are guided through with their exposed, bent wire ends | ⁽

■&igr; in the free end of the plug socket, rest on its outside. |>

The invention therefore eliminates the need for an additional component such as the metallic
Screw sleeve of the screw base of the known locking head, to which

the lead wires must be connected separately. In the case of the closure head according to the invention, the leads only need to be led through the plug-in base and the stripped wire ends be bent towards the outside of the plug-in base.

If necessary, it is possible to seal the cable ends when molding the closure head housing and the plug base with the plastic:

injection molding material. However, it is also possible to

through axial holes formed in the plug-in base, which on the inside of the housing base, widened in a funnel shape and are sealed there with a sealing compound surrounding the cables.

Preferably, the sections of the cables between the lamp holder and the housing base are longer than the distance between them. This allows the cable wires to be connected to the lamp holder outside the housing of the closure head, after which the assembly comprising the reflector and the lamp holder attached to it is introduced into the housing. This subsequent assembly option of the assembly comprising the reflector and the lamp holder attached to it, to which the cables are already electrically connected, also enables access to the inside of the housing base of the closure head in order to apply the sealing compound to close the holes through which the cables are led out of the closure head using a spray head.

To further simplify assembly, a design of the locking head is preferred in which the lamp holder is clamped into a central hole of the reflector and the reflector is clamped or locked into the open housing end.

The invention is explained using a preferred embodiment of the locking head, which can be seen in the figure of the drawing in the axial section through the locking head.

The closure head 2 shown in the drawing consists of a hollow cylindrical housing 7 made of a plastic material, the housing base 7' of which is hollow-conical and has a central plug-in base 20 on its outside. A lamp holder 13 with a reflector 15 for screwing in a lamp J4 is arranged in the open end of the cup-shaped housing 7. To supply power to the lamp J4 , electrical lines 18 are connected to the holder 13, which are led out of the interior of the housing 7 through axial holes 21 in the plug-in base 20 and whose stripped free wire ends 13 are bent back against the outside of the plug -in base 20. The funnel-shaped, widened inner end of the holes 21 is sealed by a sealing compound 22 surrounding the lines 18.

The closure head 2 is inserted with its cup-shaped housing 7 into the balloon neck la of a balloon 1, so that its balloon neck la and the edge bead l'a present thereon are held sealingly on the outer circumference of the housing 7 and the interior of the balloon 1 is illuminated after the lamp J4 is switched on.

At the lower end of the housing 7, a filling nipple 16 is formed, which can be closed with a plug 17 and serves to inflate the balloon after it has been placed on the housing 7. The reflector 15 has at least one air passage opening 19 so that the air for inflating of the balloon 1 can pass the reflector 15.

As can be seen from the drawing, the lamp holder 13 is clamped into a central hole of the reflector 15, whereby the wire end of one line 16 is also clamped in at the same time. The wire end of the other line 18, however, is soldered to the central pole of the lamp holder 13. The reflector 15 is locked in the open end of the housing 7 by means of locking projections 23. The sections of the lines 18 within the closure head housing 7 are considerably longer than the distance between the

2Ö lamp holder 13 and the part of the housing base 7 furthest from it, whereby the lead wires of the cables 18 can be connected to the lamp holder 13 outside the housing 7 and the sealing compound 22 can be introduced unhindered , after which the assembly consisting of the reflector 15 and the lamp holder 13 is inserted into the open end of the housing.
