Embodiment
Hereinafter, will describe the utility model in detail.
The utility model provides a kind of signal terminal structure of phono connector, extremely shown in Figure 7 as Fig. 3, this phono connector comprise as shown in Figure 7 several be laminated to each other together insulating body 4, and a plurality of confessions as shown in Figure 4 be plugged in terminal group in the insulating body 4, described terminal group comprises two pairs of signal terminals 5, is used for being plugged in jointly the earth terminal (not shown) in the insulating body 4.
As shown in Figures 3 and 4, signal terminal 5 comprises a first terminal 51 and one second terminal 52, first and second terminal 51,52 respectively has the extension 511,521 that protrudes out, wherein the extension 511 of the first terminal gives the integral type bending and forms a contact flat spring 512, and extension 511 itself further is formed with the interference piece 514 of a deviation shape by one " " shape cut 513; Wherein extension 521 free ends of second terminal then form a breach 522 that is suitable for contact flat spring 512 movable usefulness.
This first terminal 51 can earlier gold-platedly carry out required punching press again when preparation is gold-plated, therefore can be gold-plated to select the plating mode, so can save gold-plated amount.
As shown in Figure 5, when two pairs of signal terminals 5 be inserted in symmetric mode one have in the insulating body 4 of jack 41 after, the contact flat spring 512 of its each the first terminal 51 is relative each other, and the part of each contact flat spring 512 just by the breach 522 of each second terminal, contacts and make each contact flat spring 512 get freely to bring in each second terminal 52 with it.The interference piece 514 of each the first terminal 51 is then in order to interfering in the inwall of described insulating body 4, thereby realizes the function of each the first terminal 51 of strong fix.
As shown in Figure 6, when in the jack 41 (seeing Fig. 5 for details) that a plug 6 is inserted insulating bodies 4, can strut the contact flat spring 512 of its left and right sides relatively, and realize the purpose of contact conducting, and two contact flat springs 512 of this moment are no longer contacted with each second terminal 52 owing to strut relatively.
Please consult Fig. 5, shown in Figure 6 again, when the insertion of described plug 6 or withdraw from jack 41 and two contact flat springs 512 are strutted relatively or when resetting relatively, each contact flat spring 512 utilizes the corresponding breach 522 of each second terminal 52, is used as each contact flat spring 512 activity space of knee springing back and forth.
As shown in Figure 7, several insulating bodies 4 formula that is laminated to each other is combined, and respectively plugs two pairs of terminal group in each insulating body 4, and is inserted with an earth terminal (not looking among the figure) more jointly between all insulating bodies 4, so forms this phono connector with structure.
In sum, the utlity model has following characteristics and advantage:
(1) because the first terminal 51 direct one have described contact flat spring 512, need not secondary operations thereby realize, manufacture process simply and the effect that is easy to assemble.
(2) because described contact flat spring 512 and 51 of the first terminals are the pattern of one, so and make the performance that the elastic force of this contact flat spring 512 can be tangible and stable, have preferable electric contact performance relatively, and no longer come in contact bad defective.
(3) because described contact flat spring 512 and the first terminal 51 and Nonseparation and integral type, thus gold-plated punching press more earlier aspect gold-plated, thus can be gold-plated to select the plating mode to come to contact flat spring 512, so can save consumption gold amount and reduce cost.
Be understandable that; for the person of ordinary skill of the art; can make other various corresponding changes and distortion according to the technical solution of the utility model and technical conceive, and all these changes and distortion all should belong to the protection range of the utility model accompanying Claim.
