    The present invention relates to a power supply technology capable of preventing a short circuit even under stormy weather such as outdoor rainy weather, snowfall, and the like, and in particular, a rectifier that can supply power to an outdoor LED decoration more safely. From the field of providing and selling equipment and equipment necessary for its transportation, storage, assembly and installation, as well as the field of manufacturing and providing products, materials necessary for those materials, machinery and parts, for example, , Wood, stone, various fibers, plastics, various metal materials, etc., electronic components incorporated in them, control-related equipment that integrates them, fields of various measuring instruments, power to move the equipment and instruments Fields generally called industrial machinery such as the field of machinery, electric power that is energy, and electricity and energy that are energy sources, as well as testing these facilities and equipment, Research, field related to display, sales, import / export, general or related to the results of their use and the collection and transportation of garbage debris generated by the operation of equipment and equipment There are not many technical fields that are not related to the fields, such as the recycling field that efficiently recycles garbage waste, and new fields that cannot be envisaged at this time.

(Points of interest)
Illumination using LED (light emitting diode: hereinafter omitted) illumination lamps are generally supplied from a commercial AC power source through a rectifier circuit and supplied with a DC current converted into a daisy chain. It is designed to light up a plurality of connected LED lighting lamps. Especially, in the case of outdoor installation, rainwater or the like enters each part of the power plug, power cord, rectifier circuit, string, connector, etc. In particular, the connector part that connects the LED lighting string and the rectifier circuit is high so that the male and female connectors are completely fitted together during installation work. Although designed and manufactured to ensure hermeticity, if male and female connectors are not properly tightened, the gap between male and female connectors There is a risk of intrusion of rainwater, snowmelt, and other water. Also, if LED lighting is wired and installed during rainy weather or snowfall, rainwater or snow will enter between the male and female connectors. In such a case, even if it is possible to ensure stable lighting of the lighting at the beginning of installation, for example, until the start of use after the second year or during use The metal contained in the electrode gradually ionizes due to rusting on the electrode part of the male / female connector, etc., heat due to humidity and current, and the electric field generated between the positive and negative electrodes. Even if it does not completely short-circuit, such as when an ion migration phenomenon occurs in which it moves between electrodes along the bonding interface between resin molded parts and reduces again to metal and precipitates, etc. Ten Ω resistance In such a failure, even if the rectifier circuit is equipped with a large current protection fuse that is effective when the rated current is greatly exceeded, the fuse may be damaged. The circuit will not open, current will continue to flow between the positive and negative electrodes and heat will be generated, and the resin part forming the outer shell of the connector will be heated, ignited, smoked, etc., leading to connector damage, and further due to connector damage There was concern that a large current would flow due to a short circuit, leading to damage to the rectifier circuit.

(Conventional technology)
In light of this situation, proposals that can be used to overcome this situation are not uncommon.
For example, as typified by those proposed in the following Patent Document 1 (1) and Patent Document 1 (2), a female connector in a male / female connector that is detachable in a pair is shown. A technology for preventing a short circuit between the electrodes by extending a creeping distance between both electrodes in a connected state by providing a partition wall between the electrodes and providing a groove portion between the electrodes of the male connector so that the partition wall can be inserted. Alternatively, an LED composed of a rectifier circuit that rectifies and outputs an AC input of a commercial AC voltage, and a plurality of LEDs connected in series with the output as input, as shown in Patent Document 1 (3), is used. In this image display device, a varistor is connected between the AC input lines, and an overheat protection circuit is connected in series with the plurality of LEDs, and the varistor prevents inflow of a surge voltage from a commercial AC power source. Image display equipment Disruption while preventing the, such as the image display apparatus is it possible to provide an image display apparatus using the LED to prevent that generates heat above a predetermined temperature is scattered by the overheat protection circuit.

However, the thing which provided the partition wall between the electrodes of the connector as shown in the former patent document 1 (1) and the patent document 1 (2) and extended the creepage distance is caused by the ion migration phenomenon and the phenomenon. Although it is possible to effectively prevent the occurrence of a partial short, it is still possible to cause a partial short in the connection part of the male / female connector, or in the middle part of the string or in the connecting part. In such a case, there is a possibility that the occurrence of a partial short circuit or the heating, ignition and smoke of the rectifier circuit cannot be surely prevented. Furthermore, each male / female connector, for example, the male connector has its own wall thickness. Molded parts in the case of two or more molded parts combined to have a coupling interface between the positive and negative wires placed inside There is a risk that an ion migration phenomenon will occur between the positive and negative wirings along the bond interface between the conductors, resulting in a partial short, and an image display device represented by Patent Document 1 (3) For example, the AC power supply is provided to the side of the rectifier circuit with a fuse and varistor, and a heating protection circuit comprising a resistance element having positive temperature characteristics such as Posister (registered trademark) or polyswitch (registered trademark) The LED and the varistor can prevent the inflow of a large current into the rectifier circuit, but the heating protection circuit protects the LED from abnormal heating. It is not intended to protect the rectifier circuit, and what are these fuses, varistors, rectifier circuits, and heat protection circuits? However, it does not have a positive waterproof structure, and it can protect the image display device from large currents such as surge currents caused by lightning strikes, etc., and can prevent heat generation due to light emission of LED and damage under high temperature environment. It is possible to reliably prevent the occurrence of ion migration phenomenon that can occur anywhere in the wiring circuit due to moisture ingress or heating, and the failure of the partial short mode due to it. It wasn't.

(Awareness of problems)
As described above, the various connectors that have been proposed so far can prevent the ion migration phenomenon and the partial short circuit caused by it from occurring in the wiring part other than the connection part between the male and female connectors. In addition, for image display devices using LEDs that have a heating protection circuit in the LED gap (DC gap) rather than the rectification circuit, use the rectification circuit etc. outdoors. It is not a premise, and if the water enters any part of the range from the AC input to the rectifier circuit, there is a risk of failure in the partial short mode due to the ion migration phenomenon. The applicant has left the shortcomings, and the applicant of the present application has been engaged in the development, manufacture, and sale of LED lighting for many years, and continues to provide it to various customers. Based on various knowledge obtained from them and information from users, it is possible to repeat the trial production and experiment, and more reliably prevent the ion migration phenomenon inside the male / female connector wall thickness.

Can be.

    As shown in FIGS. 14 and 15, the outdoor LED electrical rectifier 1 according to the present invention without the fuse 6 as the large current protection circuit 6 is provided with the polyswitch 5 (registered trademark) shown in FIG. 14. When an overcurrent of 1A to 6A occurs, the polyswitch 5 (registered trademark) trips to suppress the rated current and prevents a partial short circuit. When a large current exceeding 6A occurs The circuit is opened due to either damage to the polyswitch 5 (registered trademark) or the fusing of the resistors 83, 83, 83 of the connected LED extended string 8 for LED lighting. When the circuit protector 50 shown in FIG. 15 is provided (on the performance of the circuit protector 50 currently on the market) 1 To when an overcurrent of 2A occurs, it can not prevent the partial short, if the 3A to overcurrent exceeding 6A occurs, circuit protector 50, automatically becomes the circuit open.
