Description

Six-flap mouth MMCX micro-expansion contact pin structure

Technical Field

The utility model relates to a MMCX contact pin technical field specifically is a six lamella mouth MMCX micro-expansion contact pin structures.

Background

At present, many middle-high-end earphones are designed by adopting MMCX interfaces, so that free matching of different wires and earphones can be realized, and the earphone is really a design which is most convenient for earphone fever sufferers who like the wire of the; meanwhile, the MMCX interface also has the advantages of good shielding effect and the like. Specifically speaking, the earphone wire rod sets up MMCX radio frequency terminal contact pin, the earphone main part sets up the female seat of MMCX, makes and realizes convenient free plug between earphone wire rod and the earphone main part.

But the current market has the design of standard non-slotted traditional MMCX radio frequency terminal contact pin and two-valve mouth, three-valve mouth and four-valve mouth expansion type MMCX radio frequency terminal contact pin, the traditional MMCX radio frequency terminal contact pin is inserted into the MMCX female seat and then realizes the positioning and contact of the negative pole by means of the internal clamping groove of the female seat to shrink the clamping ring, but because a gap is easy to generate unstable shake between the outer barrel body without the slotted pin and the inner hole of the female seat, and the expansion type MMCX radio frequency terminal pin with the valve mouth, the three-valve mouth and the four-valve mouth is designed, because the valve mouths are fewer in number, the elastic force generated by the single valve mouth when the single valve mouth deforms with the same amplitude is overlarge, and the pressure on the inner wall of the inserted female seat is overlarge, the female socket is easy to wear and cause poor contact after long-term use, and the plug is also easy to have the problem that the plug cannot be restored and rebounded to cause poor contact because the deformation is too large and exceeds the elastic limit. Meanwhile, the elastic sheet is easy to break due to the contraction and shaking of the elastic sheet in the using process. To this end, we have designed a six-lobed MMCX micro-expansion structure pin.
