Description

Wire rod waterproof construction and power shell who has this wire rod waterproof construction

Technical Field

The present invention relates to a waterproof structure for an electronic device, and more particularly to a waterproof structure for a wire and a power supply housing having the same.

Background

Due to the rising of energy saving and environmental protection awareness, Light-Emitting Diode (LED) lighting has the advantages of energy saving, high Light-Emitting efficiency, long service life, environmental protection, no mercury, small volume and the like, so that the LED lighting lamp has largely replaced the traditional bulb which is fragile and consumes power, and is widely applied to the daily life of human beings. However, whether using LED lamps or using conventional lamps, users want the lighting lamps to have good waterproof effect and long service life. Most of the time, the waterproof effect of the LED driving power supply directly influences the waterproof effect of the whole LED lamp; and the structure of the LED power supply shell and the design of the waterproof wire directly influence the waterproof effect of the whole power supply. Therefore, how to develop a housing and a wire of an LED power supply with good waterproof effect and durability has been a subject of active development and development of related industries.

Referring to fig. 1, a perspective view of a conventional LED power supply housing is shown. As shown in fig. 1, a conventional wire waterproof structure 1 ' is disposed at a mounting hole of a power supply case 2 ' through a circular elastic ring 11 '. And, the outer side of the circular elastic ring 11 ' is formed with a tabling part, through which the wire waterproof structure 1 ' is arranged at the mounting hole of the power supply housing 2 '. Although the conventional wire waterproof structure 1 'has a waterproof effect, the circular elastic ring 11' is soft and is easily deformed by an external force. It is conceivable that when the circular elastic ring 11 'is deformed by an external force, a gap is formed between the wire and the circular elastic ring 11', so that water drops easily penetrate into the power supply housing 2 ', and damage and failure of the power supply housing 2' are caused. On the other hand, since the wire waterproof structure 1 'is fastened to the power supply housing 2' through an engaging portion of the circular elastic ring 11 ', it is conceivable that the engaging portion is easily detached from the power supply housing 2' when the wire is pulled by an external force. As can be seen from the above, the conventional waterproof structure 1' for wire rod has not only a poor waterproof effect but also a small external force to be borne by the wire rod portion.

With reference to fig. 1, fig. 1 further includes another conventional wire waterproof structure 3 ', as can be seen from fig. 1, the conventional wire waterproof structure 3' is fixed to the power supply housing 2 'by a fixing member 13', and is formed with an internal thread by a locking member 14 ', and is further locked to an external thread of the fixing member 13' by the internal thread. Since the fixing member 13 'and the locking member 14' are made of Polyvinyl Chloride (PVC) for preventing deformation, it is conceivable that one or more elastic washers must be disposed between the components of the wire waterproof structure 3 'to achieve a good waterproof effect, which results in a lot of components of the wire waterproof structure 3'. Although, the above-mentioned existing wire rod waterproofing structure 3' has a good waterproofing effect; however, the complex structure leads to high cost, and the assembly is time-consuming, which results in increased time cost and reduced manufacturing yield.

As can be seen from the above, the conventional power supply housing 2' has a waterproof design, which is still insufficient. In view of the above, the inventor of the present invention has made research and creation as much as possible, and has finally developed a wire waterproof structure of the present invention.
