[ detailed description ] embodiments
Referring to fig. 1, the present embodiment provides a connector adapter, which includes a first connector 10, a second connector 20, and a connecting wire 40 connected between the first connector 10 and the second connector 20.
The connecting wire 40 includes a body 42. The body 42 includes a first stress relief portion 422, a flat connecting portion 424, and a second stress relief portion 426. The first stress relief portion 422 is connected between the first connector 10 and the connection portion 424, and the second stress relief portion 426 is connected between the second connector 20 and the connection portion 424. The first stress relief portion 422, the connecting portion 424 and the second stress relief portion 426 are integrally formed. Through this kind of structure, connecting portion 424 adopts the platykurtic structure, cylindrical connecting portion relatively current, its compliance is good, and it can only buckle towards two directions to have injectd connecting portion 424, and the thickness of being buckled department is thin consequently be difficult to the rupture, simultaneously with first stress relief portion 422, connecting portion 424 and second stress relief portion 426 integrated design, can make whole body 42 can both be used for releasing to drag the produced stress of the in-process of dragging connecting wire 40, the ability of release stress has been improved, thereby the bending resistance and the mechanical properties of bending resistance of connecting wire 40 have been improved, the risk of rupture has been reduced, long service life, the number of times of average bending resistance can reach more than 10000 times.
Further, the first stress relief portion 422 has a flat shape, one end of which matches the size and shape of the first connector 10, the other end of which matches the size and shape of the connection portion 424, and one end of the second stress relief portion 426 matches the size and shape of the second connector 20, and the other end of which matches the size and shape of the connection portion 424. With such a structure, the connection portion 424 and the first stress relief portion 422 and the connection portion 424 and the second stress relief portion 426 are not easily broken.
The thickness of the first stress relief portion 422 at the end near the connection portion 424 gradually increases in the direction near the first connector 10, and the thickness of the second stress relief portion 426 at the end near the connection portion 424 gradually increases in the direction near the second connector 20.
With the above structure, the flat connecting portion 424 is limited to be bent in two directions, and the bent portion is thinner and thus is not easily broken, compared to the conventional cylindrical stress relief portion having a step, and the thicknesses of the first stress relief portion 422 and the second stress relief portion 426 at the end close to the connecting portion 424 are gradually changed, so that the number of times of bending tolerance can be further increased.
