Bayonet clip made of engineering plastic (PBT)

Bayonet clip, superimposed the design and adjustment of micron accuracy, molding so that the smooth and strong hold feeling can be obtained in the "HPC-35SRH / HPC-62SRH". The resin for mold, excellent durability and dimensional accuracy, and so as not to wear the lock mechanism of the headphone body side in repeated attachment and detachment of, using the optimized engineering plastics was (PBT) the hardness.

This can surely hold the headphone, and can not bring wear the headphone body. In addition, the handle part, fitted with a brass cut out chrome-plated cover subjected to a fine knurled increments. As well as to facilitate the attachment and detachment of the cable, it brings the beauty of the texture to the bayonet clip. In addition, in 2.5φ3 pole pin of the bayonet clips, it has undergone a 18K gold-plated.

 

Use a high-quality headphone cable HPC-22W of PCOCC-A conductor

The cable portion of the "HPC-35SRH / HPC-62SRH", using the HPC-22W of Oyaide electricity obtained an impregnable position as a high-quality headphone cable. HPC-22W is compatible high-quality copper PCOCC-A conductor, fluorine resin insulation with excellent electrical characteristics, by TPE sheath with the flexibility and durability, the ease and excellent durability of maneuverability and high-quality sound .

Lineup two types of the length, the two types of terminal connector

To meet the user a wide range of situations, two types of length and (1.3m / 2.5m), 2 types of terminal plug (3.5 mini and 1 / 4TRS phone) of a total of four line up the pattern. 3.5 mini plug, HPC-Series proven in ELEC original silver + rhodium-plated "P-3.5SR," "to be adopted .1 / 4TRS phone, ELEC original silver + rhodium with a proven track record in the HPC-Series adopting the plating "P-240T-SR".

The material of the electrode portion of the "P-3.5SR" "P-240T-SR" has adopted a brass clearing the European RoHS directive. The main and the contact portion should be called of signal transmission, plated with silver of 1.5μ thickness to direct, it has undergone further 0.3μ rhodium plating of thickness on the surface. This prevents the corrosion of the contact, and contribute to the improvement of the transmission characteristics. Also to the outline of the outer shell, craftsmanship Oyaide electricity has been reflected. Carefully cut one by one by the NC machine training is carried out, precisely then chopped the knurled, Berri chrome plating have been made as well as the camera lens to the finish.

Using the acoustic dedicated solder "SS-47"

The soldering of wiring, use the ELEC electricity original acoustic dedicated solder "SS-47". Normal solder purity of the tin from the cost is 99.9% (3N) degree. "SS-47" further discharge the impurities increase the purity to the limit, adopt a high-purity tin that indeed 99.993% (4N) or more. Further improvement of the electric conductivity, are designed to prevent leaching of solder, was blended silver, copper. Moreover, the case of normal alloy solder, silver mixing ratio of is from 3 to 3.5 percent, but "SS-47" is an amazing unsparingly put the amount of 4.7%. In addition, 1.7% compounded the next in high conductivity copper of silver among metals.

Conductivity by this compounding ratio is dramatically improved, it succeeded in setting the eutectic point 217 degrees. Of course, the blending ratio of these, it has not determined only by numerical data and workability. To hit the solder and the inscription for the audio, the sound quality is considered to be appropriate to the highest priority. I was born that "SS-47" of the many times that there is no hearing test a proto model of a variety of blending ratio.
