4. When the fixing strip does not enter the cavity, the convex angle of the cam is propped against the supporting piece, so that the convex angle of the cam can be prevented from falling under the action of gravity, the convex angle of the cam is prevented from reversing when the fixing strip is inserted again, the fixing strip is guaranteed to be propped against and fixed by the convex angle, and the stability of the electric connection of the first connecting piece and the second connecting piece is improved.
5. The cam and the fixed strip are internally provided with magnetic parts, the cam and the fixed strip are attracted through the magnetic action of the first magnetic part and the second magnetic part, the first magnetic part is arranged on the convex corner of the cam, when the fixed strip enters the cavity, the magnetic action can drive the cam to rotate, the convex corner of the cam rotates to be close to the fixed strip, and accordingly the fixed strip is abutted and fixed, and the electric connection stability of the first connecting piece and the second connecting piece is improved.
6. The fixed strip is a magnetic action piece, a first magnetic piece is arranged on the convex angle of the cam, the convex angle of the cam is rotated to be close to the fixed piece through the magnetic action of the magnetic action piece and the first magnetic piece, so that the cam is abutted against the fixed piece, the electric connection stability of the first connecting piece and the second connecting piece is further improved, and poor contact is avoided.
7. The contact terminal can transmit electric signals between the first connecting piece and the second connecting piece, the contact terminal is arranged on the protrusion and the groove, the contact terminal is attached after the protrusion is matched with the groove, and therefore the electric signals can be transmitted between the first connecting piece and the second connecting piece, and the attaching degree of the first connecting piece and the second connecting piece is increased.
8. The fixing piece is matched with the slot in shape, the fixing piece is made of flexible materials, and can be pressed into the slot, so that the first connecting piece and the second connecting piece can be fixed close to one end far away from the fixing strip, the degree of fit between the contact terminals is higher, and poor contact of the contact terminals is avoided.
9. The first connecting piece, the fixed strip is supported through the cam and then fixed hugs closely to the second connecting piece, the fixed strip is when getting into the opening, stay one end time in the open position, can be under the magnetic action, the lobe rotation of cam is close to the fixed strip, the fixed strip is inserting the cavity gradually, under the magnetic action, the lobe of cam rotates gradually and is close to the fixed strip, after fixed strip and lobe contact, the fixed strip drives the lobe to go deep into the cavity, the lobe is tightly supported and held the fixed strip gradually, thereby it is fixed to support the fixed strip, keep laminating closely between first connecting piece and the second connecting piece, the electric connection stability between reinforcing first connecting piece and the second connecting piece, guarantee that the electrical signal is steadily transmitted, prevent information transmission's in-process from losing, guarantee that the user has good use experience, further, when passing through multiple plug, the position that fixed strip and cam contact appears wearing and tearing, when the fixed strip inserts, the cam rotates more angles under the effect, thereby support and hold on the fixed strip continuously to keep being held by the state, can avoid the condition that the plug leads to contact failure to appear many times.
