Description

A kind of vehicle power signal plug

Technical field

This utility model relates to a kind of electric connection structure, more specifically, it relates to a kind of vehicle power signal plug。

Background technology

Along with the development of society, improving constantly of the living standard of people, motor vehicles are increasingly entering family, have been the transport that people's daily life is necessary。For convenience of the use of each class of electronic devices such as mobile phone, MP3, notebook computer, in automobile, it is provided with vehicle power。

At present, on market application number be 201420074848.4 Chinese patent disclose a kind of vehicle power signal plug, it includes vehicle-mounted power socket body, and the structure of vehicle-mounted power socket is the hollow rectangular structure of recording quantity；The one side of vehicle-mounted power socket is provided with mounting groove, installing hole and crosses terminal；Vehicle-mounted power socket is respectively arranged with positioning baffle in the two sides adjacent with being provided with mounting groove；It is provided with die cavity and draw-in groove in vehicle-mounted power socket, the sidewall of die cavity is provided with standoff tab；Being additionally provided with metal contact piece in die cavity, one end of metal contact piece is arranged in die cavity, and the other end stretches out vehicle-mounted power socket。

In such scheme, installing hole is coordinated to be fixed in the circuit board by vehicle power body, and the upper surface of outer cover extension area of installing hole correspondence position is bigger, after moulding, fixed half and moving half is likely to result in upper surface of outer cover and is adsorbed when separating, it is impossible to separating in time, the flatness that so can cause upper surface of outer cover is relatively low, also the axially vertical degree of installing hole can be affected, insecure after causing vehicle power body to be fixed on wiring board。

Utility model content

For the deficiency that prior art exists, the purpose of this utility model is in that the vehicle-mounted power socket providing a kind of demoulding rear casing upper surface flatness higher。

For achieving the above object, this utility model provides following technical scheme: a kind of vehicle power signal plug, including housing and metal contact, described housing is provided with installing hole, and described housing is circumferentially with some de-hoppers along installing hole。

Pass through technique scheme, after press mold molding, de-hopper decreases adsorption area in dynamic model with cover half separation process, therefore de-hopper ensure that the outer surface of housing will not be adsorbed by dynamic model when separating, corresponding installing hole is not easy the deformation that is stretched, it is ensured that the axial location accuracy of installing hole；Decrease the use of material simultaneously on the other hand, provide cost savings。

This utility model is further arranged to: be provided with reinforcing plate in described de-hopper。

By technique scheme, reinforce plate and improve the structural strength of housing, decrease the trend of de-hopper deformation。

This utility model is further arranged to: described metal contact is provided with groove。

By technique scheme, the structure of groove adds the area being welded and fixed, it is provided that more fixed position, and the corresponding metal contact area that is welded and fixed in the circuit board increases, it is achieved that stability higher after assembled formation。

This utility model is further arranged to: housing is provided with groove of loosing core。

By technique scheme, groove of loosing core is arranged at the dorsal part of housing cavity corresponding to pin, and its effect is pressure release effect after press mold molding, it is to avoid after fixed half and moving half separates, housing itself cannot take off due to atmospheric pressure, groove of loosing core arrange simple and effect is obvious。

This utility model is further arranged to: housing is provided with gathering sill。

By technique scheme, the effect that when gathering sill provides plug grafting, guiding coordinates, be equivalent to provide guide rail during grafting, decrease maloperation during grafting, the guide rail of gathering sill both sides also has the effect of clamping, has therefore reached higher cooperation tightness。

Fig. 2 is the three-dimensional view of this utility model embodiment。

Accompanying drawing labelling: 1, housing；2, metal contact；3, installing hole；4, de-hopper；5, plate is reinforced；6, groove；7, loose core groove；8, gathering sill。

Detailed description of the invention

Referring to figs. 1 through Fig. 2, this utility model embodiment is described further。

A kind of vehicle power signal plug, including housing 1 and metal contact 2, housing 1 is provided with installing hole 3, and housing 1 is circumferentially with some de-hoppers 4 along installing hole 3；By such setting, after press mold molding, de-hopper 4 decreases adsorption area in dynamic model with cover half separation process, therefore de-hopper 4 ensure that the outer surface of housing 1 will not be adsorbed by dynamic model when separating, corresponding installing hole 3 is not easy the deformation that is stretched, it is ensured that the axial location accuracy of installing hole 3；Decrease the use of material simultaneously on the other hand, provide cost savings。

Preferably, it is provided with reinforcing plate 5 in de-hopper 4；By such setting, reinforce plate 5 and improve the structural strength of housing 1, decrease the trend of de-hopper 4 deformation。

Preferably, metal contact 2 is provided with groove 6；By such setting, the structure of groove 6 adds the area being welded and fixed, it is provided that more fixed position, and corresponding metal contact 2 area that is welded and fixed in the circuit board increases, it is achieved that stability higher after assembled formation。

Preferably, housing 1 is provided with groove 7 of loosing core；By such setting, groove 7 of loosing core is arranged at the dorsal part of pin corresponding housing 1 inner chamber, and its effect is pressure release effect after press mold molding, it is to avoid after fixed half and moving half separates, and housing 1 itself cannot take off due to atmospheric pressure, groove 7 of loosing core simple and effect is set substantially。

Preferably, housing 1 is provided with gathering sill 8；By such setting, the effect that when gathering sill 8 provides plug grafting, guiding coordinates, be equivalent to provide guide rail during grafting, decrease maloperation during grafting, the guide rail of gathering sill 8 both sides also has the effect of clamping, has therefore reached higher cooperation tightness。

The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to above-described embodiment, and all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model。It should be pointed out that, for those skilled in the art, without departing from the some improvements and modifications under this utility model principle premise, these improvements and modifications also should be regarded as protection domain of the present utility model。
