In another specific embodiment, electric connection plug provided by the invention, header body includes support portion 2 and divides
The first support arm 3 and second support arm 4 not extended outward to form by the top and lower part of 2 side of support portion, including multiple set side by side
The contact terminal 1 set, multiple contact terminals 1 are embedded in 3 inside of first support arm.In this embodiment, main it is emphasised that plug sheet
Another concrete structure of body, the structure of contact terminal 1 and the form etc. of magnetic element 7 please refer to foregoing embodiments, herein not
It repeats again.
In this embodiment, header body includes support portion 2, first support arm 3 and second support arm 4.It is propped up based on support portion 2
Support structure, first support arm 3 and second support arm 4 are extended outward to form by the side upper and lower part of support portion 2 respectively.Contact terminal
1 be set side by side with it is multiple, and multiple contact terminals 1 respectively be embedded in first support arm 3 and inside.It should be noted that herein interior
Side, which refers to, is electrically connected plug under 180 ° of axis overturning and another electric connection plug fastening state, 3 inside of first support arm.With
One support arm 3 is located at the top of 2 side of support portion, second support arm 4 is located at for the lower part of 2 homonymy of support portion, then first support arm 3
Inside is the lower face of first support arm 3.Specifically, multiple contact terminals 1 can be evenly distributed in first support arm 3.
In the embodiment, after one is electrically connected plug and another electric connection plug axis is aligned along longitudinal direction, wherein one
A electric connection plug is on the inside of the first support arm 3 of an electric connection plug and another electrical after transverse axis rotates 180 °

Portion, and the distance between the upper surface of the first support arm and the top surface of support portion 2 are equal to the thickness of second support arm 4.And then two is electric
Property connection plug to insert after, second support arm 4 is parallel with the end face of support portion 2, and overall structure is more regular, also avoids due to two
Person's difference in height and be easy by other structures hook etc. cause two electric connection plugs surprisingly to disconnect.
In the above embodiments, contact terminal 1 includes flat segments and the tip-angled shape raised section for being connected to straight g. slice header,
It is electrically connected plug and overturns 180 ° under another electric connection plug fastening state around axis, two are electrically connected the raised section of plug
It abuts.Specifically, flat segments are an integral structure with raised section, by the setting of flat segments, convenient for consolidating contact terminal 1
Due in header body.The head setting tip-angled shape raised section of flat segments, the raised section of two electric connection plugs offset, on the one hand
It provides in electrical contact to transmit audio signal, while engaging can be played the role of, it is further provided be electrically connected inserting for plug
Pull out force so that two are electrically connected the electrical of plug and are mechanically connected more reliable.
In the above embodiments, the top of clamp 6 is fixed with magnetic element 7, and the slot bottom of card slot 5 is fixed with magnetic element
7.In turn, one be electrically connected plug and another electrics connection plug axis be directed at along longitudinal direction after, one of them electric connection is slotting
For head after transverse axis rotates 180 °, the clamp 6 and card slot 5 of one are opposite with the card slot of another one 5 and clamp 6 respectively, are formed
Two groups of engagings, meanwhile, the magnetic element 7 of 5 slot bottom of magnetic element 7 and another one card slot on 6 top of clamp of one is attracted, and preceding
The magnetic element 7 of 5 slot bottom of card slot of person and the magnetic element 7 on 6 top of clamp of the latter are attracted, and are formed two groups of magnetic attractings and are made
With.Certainly, those skilled in the art it is conceivable that the magnetic element 7 of the magnetic element 7 and 5 slot bottom of card slot on 6 top of clamp choosing
It selects and magnetic pole setting should be able to provide magnetic attracting power.Such as the magnetic element of the magnetic element 7 and 5 slot bottom of card slot on 6 top of clamp
7, one of the two is permanent magnet, and another one is ferrimagnet part, or both for permanent magnet, and the magnetic pole phase in outside
It is different, or both for electromagnet, and the magnetic field formed be located at outside magnetic pole it is different, to ensure magnetic attracting.
