As a preferred embodiment：The positioning clamping pin includes base portion and is set to the inserting part of base portion front end, this is inserted The portion of putting be inserted between core wire and insulating base gap and with the close clamping of base rear end that insulate, base portion is blocked on the outside of insulating base.

As a preferred embodiment：The crust is acetic acid cloth.

As a preferred embodiment：The acetic acid cloth is coated in oblique outside core wire.

As a preferred embodiment：The bending angle of the curved bend folding part is less than 90 degree.

The utility model has clear advantage and advantageous effect compared with prior art, specifically, by above-mentioned technology Scheme on the pair plug of left control line and right control line it is found that by setting positioning clamping pin, and using positioning, the enhancing of the card tip is secondary to insert Head and the pulling force at core wire riveting position, prevent core wire from coming off from secondary plug；In addition, in left control line and the core wire of right control line Tail end setting curved bend folding part, the personnel that are convenient to operation carry out the layout designs of harness according to entrucking angle, avoid traditional line Break phenomenon caused by the multiple bending of profile and wire, improves product qualification rate.

More clearly to illustrate the structure feature and effect of the utility model, come below in conjunction with the accompanying drawings with specific embodiment pair It is described in detail.
