Embodiment
See also Fig. 1 to Fig. 5.The utility model electronic installation comprises plastic body 1 and the antiseepage electric connection terminal 2 that is connected on the plastic body.In this specific embodiment, antiseepage electric connection terminal 2 is connected by quadric injection mould with described plastic body.
Antiseepage electric connection terminal 2 comprises metal terminal 21 and moulding 22.Moulding 22 is connected with metal terminal by injection moulding.Wherein, metal terminal 21 comprise the outside electrically contact the end 211, internal electrical contact jaw 212 and be connected to the outside electrically contact the end and the internal electrical contact jaw between connecting portion 213.The outside electrically contacts end 211 and is mainly used in exposing to be electrically connected with other accessories, and internal electrical contact jaw 212 is mainly used in being connected with the internal circuit of electronic installation.The number of metal terminal 21 arranges according to the concrete condition of concrete electronic installation.The outside electrically contacts end, the internal electrical contact jaw exposes described plastic body, and described connecting portion is wrapped up by described plastic body.
Be provided with through hole 2131 on the connecting portion 213.Arranging of through hole 2131 mainly is tightr that metal terminal contacts with moulding when making injection moulding, simultaneously, increase water when making the injection moulding of antiseepage electric connection terminal on plastic body and electrically contact end from the outside and enter the resistance of internal electrical contact jaw by connecting portion, thus so that the better effects if of waterproof infiltration.Through hole can arrange one, also can arrange a plurality ofly, and in this specific embodiment, through hole is provided with two.
The outward flange of connecting portion 213 is given prominence to formation protuberance 2132 in described through hole towards the outward flange outside that connects.In this specific embodiment, protuberance 2132 is circular arc.Protuberance is mainly used in increasing connecting portion at the area of through hole, to guarantee that connector is in the intensity of through hole, simultaneously, increase water when protuberance also can make the injection moulding of antiseepage electric connection terminal on plastic body and electrically contact end from the outside and enter the resistance of internal electrical contact jaw by connecting portion, thus so that the better effects if of waterproof infiltration.
