Description

  The present invention relates to a power connector and a safety cap using the power connector, and more particularly to a safety cap capable of extending a lighting duration by connecting a power connector that prevents detachment and a large-capacity battery.

  In general, people entering and leaving industrial sites such as construction sites, shipyards, and mines are legally required to wear safety caps. In Japan, where earthquakes occur frequently, they are used in schools and subway station buildings. It has a proper number of safety caps.

  Such a safety cap is provided with a light that illuminates the front when the safety cap is worn so that the field of view can be secured even in a dark place in case of a disaster such as a fire or an earthquake.

  This is to make it possible to search for a retreat path in an environment where the power supply to the building or mine is cut off and not illuminated when a disaster occurs.

  In addition, there are those in which a safety cap is lighted for workers who work in a dark place. When lighting is added to the safety cap in this way, a battery for supplying power to the lighting is essential.

  As conventional techniques for supplying power to the illumination in this way, there are Patent Literature 1 and Patent Literature 2 in which a battery is housed inside the safety cap for driving the blower fan, although it is not illumination.

  The conventional technology as described above is to use a safety cap with a battery attached, and considering that the safety cap is to be worn on a person's head, the weight increases, and thus there are various problems. It is easily predicted that dots are likely to occur.

  Due to the increase in weight, workers wearing safety caps may feel inconvenience when working and may be relatively difficult to evacuate when a disaster occurs. In consideration of this, when the weight of the battery is reduced, there is a problem that the duration of illumination is shortened and the effectiveness is lost.

  For this reason, when the battery is attached to the waist or another position separated from the safety cap and the battery and the safety cap are connected by electric wires, the wires are hung up during work, which is inconvenient. It is expected that there will be a problem that the wire connecting the wire is often detached.
