Embodiment
Refer to Fig. 1 to Fig. 5.The antiseepage electric connection terminal 2 that electronic installation of the present invention comprises plastic body 1 and is connected on 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 connecting portion 213 that comprises external electrical contact end 211, internal electrical contact end 212 and be connected between external electrical contact end and internal electrical contact end.External electrical contact end 211 is mainly used in exposing to be electrically connected with other accessories, and internal electrical contact end 212 is mainly used in being connected with the internal circuit of electronic installation.The number of metal terminal 21 is arranged according to the concrete condition of concrete electronic installation.External electrical contact end, internal electrical contact end expose described plastic body, and described connecting portion is wrapped up by described plastic body.
Connecting portion 213 is provided with through hole 2131.The setting of through hole 2131 mainly in order to metal terminal when making injection moulding contact with moulding tightr, simultaneously, increase water when making the injection moulding of antiseepage electric connection terminal on plastic body and entered the resistance of internal electrical contact end from external electrical contact end by connecting portion, thus make the better effects if that prevents water penetration.Through hole can arrange one, also can arrange multiple, and in this specific embodiment, through hole is provided with two.
The outward flange of connecting portion 213 in described through hole towards the outward flange formation protuberance 2132 protruding outside connected.In this specific embodiment, protuberance 2132 is in circular arc.Protuberance is mainly used in increasing the area of connecting portion in through hole, to ensure the intensity of connector in through hole, simultaneously, increase water when protuberance also can make the injection moulding of antiseepage electric connection terminal on plastic body and entered the resistance of internal electrical contact end from external electrical contact end by connecting portion, thus make the better effects if that prevents water penetration.
Connecting portion 213 connecting portion is also horizontally arranged with the impression 2133 of at least one depression.Increase water when impression is equally for making the injection moulding of antiseepage electric connection terminal on plastic body and entered the resistance of internal electrical contact end from external electrical contact end by connecting portion, thus make the better effects if that prevents water penetration.
In order to make metal terminal when injection moulding and Contact more tight of moulding, strengthening bonding strength between the two, connecting portion 213 also scribbles one deck silane glue before injection moulding.
Please also refer to Fig. 6 and Fig. 7.Because metal terminal is smaller, and general antiseepage electric connection terminal has multiple metal terminal, for the ease of manufacturing, usually first multiple metal terminal 21 is produced on a metalwork 3, its length is selected according to the metal terminal number that injection moulding needs, and then metal terminal and moulding are linked together by injection moulding, finally just metal terminal is cut off from metalwork.
The present invention by arranging through hole on the connecting portion of antiseepage electric connection terminal, due to the setting of through hole, make the connecting portion of metal terminal tightr when being connected with moulding, and, increase water enters internal electrical contact end by connecting portion resistance from external electrical contact end when making the injection moulding of antiseepage electric connection terminal on plastic body, thus make the better effects if that prevents water penetration.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
