Definitions
- the present invention relates to a safety device for miniature decorative bulbs.
- the garlands and light curtains for illuminations consist of small electric lamps arranged at regular intervals along supply cables and mounted directly on them.
- the device is supplied from the mains voltage (generally 230 volts) by a main cable comprising branches connected in parallel and each formed of a loop on which the lamps are mounted in series so as to be supplied individually with low voltage.
- mains voltage generally 230 volts
- These lamps generally consist of a glass bulb 1 containing a filament 2 whose ends pass through the wall and are directly on the conductors of the power cable 3.
- the base of the bulb 1 and a portion of the cable 3 are trapped in a tube 4 most often made of silicone coated with a PVC sheath ( Figure 1).
- the standards in force impose that, on the one hand, the live elements cannot be touched in the event of accidental breakage of the bulb and, on the other hand, that the latter cannot be torn off unless very effort important.
- the tests Approval for this type of material is carried out by exerting 50 successive pulls of 30 newtons on a bulb.
- the purpose of the device according to the present invention is to guarantee high security for garlands and light curtains with miniature lamps by ensuring protection from tearing out of the bulbs and by preventing access to the conductive parts thereof when they are broken. .
- sleeve of transparent synthetic material enclosing the bulb and the end of the conductors of the power supply cable, said sleeve being either molded directly onto the bulb and the cable, or formed of a heat-shrinkable tubular element. whose length is determined so that it exceeds the front of the bulb enough to prevent access to live parts when it is broken, and that it grips a length of power cable large enough to ensure a solid assembly of the whole.
- FIG. 1 is an axial section of a miniature lamp for a garland not fitted with a safety sleeve
- Figures 2 and 3 show under the same conditions a lamp of the same type equipped respectively with a heat-shrinkable safety sleeve, and a molded sleeve
- FIG. 4 is an enlarged cross-section along the arrows FI of FIG. 3.
- the device consists of a sleeve 5, 6 transparent or translucent, colored or not, made of heat resistant synthetic material enclosing both the miniature bulb 1 and the end of the power supply cable 3 so as to make the assembly formed by the power cable and the bulbs integral.
- the sleeve consists of a tubular heat-shrinkable element 5 covering the end of the cable conductors
- this length must be greater than three times the diameter of the bulb 1 ( Figure 2).
- the standard imposes an extension length of 6.5 mm.
- the device consists of a molded sleeve 6 on the bulb 1 and the end of the conductors of the cable 3 ( Figure 3).
- the material constituting the sleeve 6 may be rigid and sufficiently resistant to prevent it from being crushed under the conditions of use which may be encountered when using garlands or light curtains. As an indication, it may be polycarbonate or a similar material.
- This material may, on the contrary, be flexible so as not to split or open in the event of crushing.
- the sleeve In order to obey safety standards, the sleeve, whether it is heat-shrinkable 5 or overmolded 6, will be calculated so that the pulling out of the lamp requires traction greater than 30 newtons.
- a metal or other ring 7 may advantageously be provided, tightened on the cable insulation supply 3 and crimped in the heat-shrinkable element 5 or the overmolded sleeve 6.
