In a further arrangement, a support body is arranged at the joint of the middle main body and the pin, which is perpendicular to the direction of the first opening.

So set up, the shell fragment that makes has better stability, does not make the shell fragment not hard up and lead to contact failure because of the effort of participating in the grafting in-process to the shell fragment.

The first opening is provided with a first opening, and the first opening is provided with a second opening; and the second main body and the middle main body are provided with protrusions in a direction vertical to the first opening on mutually opposite planes.

So set up, be provided with the protrusion on corresponding surface, this protrusion can play the guide effect to participating in, has also increased the frictional force of participating in when contact shell fragment, makes to participate in and the shell fragment contact is more stable.

Furthermore, the connection place of the first connecting part and the first main body and the middle main body is in round angle transition; the second connecting part is in transition with the second main body and the middle main body through a fillet.

So set up for participate in when carrying out the effort to the shell fragment, have better buffering and extension to the deformation of shell fragment, make each part not cause contact failure because of the deformation of shell fragment.

Further, the first main body, the middle main body, the second main body, the first connecting portion, the second connecting portion, the pins, the protrusions and the supporting body are integrally formed.

So set up, increase the intensity of whole shell fragment.

(III) advantageous effects

Compared with the prior art, the utility model provides a pair of two-way shell fragment on adapter possesses following beneficial effect:

the utility model discloses a two-way shell fragment on the adapter, through first main part, intermediate main body and second main part and between them through connecting portion interconnect to corresponding first opening and second opening have been formed. The first opening and the second opening are different in size so as to be convenient for the jack matching with the size of the corresponding opening to use. When the two elastic pieces are installed, different combination arrangements can be formed to adapt to different pins for insertion and matching, so that the applicability of the adapter is improved; according to the structure, the pins are formed by extending outwards at the middle of one end of each main body far away from the connecting part. Therefore, the pins can form triangular distribution and can be matched with the PCB more stably.
