Technical field

This utility model relates to electric connector structure technical field, more specifically, it relates to a kind of vehicle-mounted power socket.

Background technology

Development along with society, improving constantly of people's living standard, 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.

Vehicle power is again power inverter, it is a kind of DC12V unidirectional current to be converted to the AC220V alternating current identical with civil power, for general electrical equipment, it it is a kind of power supply changeover device easily, vehicle power generally uses automobile storage battery or cigar lighter is powered, first such low-voltage DC is converted to the unidirectional current of about 265V, there is vehicle power, occupant just can move all of for family small household appliances to and use, such as mobile phone, notebook computer, digital camera, vehicle refrigerator, video camera, DVD etc. on car.

Vehicle-mounted power socket mainly includes vehicle-mounted power socket body and metal contact piece, vehicle-mounted power socket is all generally in use to be welded on circuit boards by metal contact piece, then plug connector is plugged on vehicle-mounted power socket body and realizes conducting by metal contact piece, the such as Chinese patent of Application No. 201420074869.6 discloses a kind of vehicle-mounted power socket, but this vehicle-mounted power socket surface does not arrange detent mechanism, and then location it is difficult to when being welded on circuit boards by vehicle-mounted power socket, poor stability, manually hold up during welding but also there may be position skew, the position causing welding is the most accurate, affect the turn-on effect in later stage, therefore it is further improved.

Utility model content

The deficiency existed for prior art, the purpose of this utility model is to provide a kind of vehicle-mounted power socket being easy to location and welding.

For achieving the above object, this utility model provides following technical scheme: a kind of vehicle-mounted power socket, including housing and metal insert, described metal insert one end is positioned at housing, it is outer for welding that the other end is positioned at housing, described housing is provided with locating dowel, offers fluting in the middle part of described locating dowel, and described fluting runs through locating dowel sidewall.

This utility model is arranged further: described locating dowel is provided with joint end away from one end of housing, and the width of described joint end is more than the width of locating dowel.

This utility model is arranged further: described joint end is pyramidal structure, and the self-align post of width of described joint end gradually decreases to the other end.

This utility model is arranged further: described housing is provided with arch, and described upper arch sidewall is provided with groove.

This utility model is arranged further: both sides, described metal insert end are provided with chamfering, is provided with and runs through groove in the middle part of described metal insert end.

Compared with prior art, the utility model has the advantage of: by arranging locating dowel on housing, therefore in use can realize just location by the through hole of locating dowel with circuit board, and in locating dowel, offer fluting, and then make locating dowel more possess certain deformability, on the one hand more easily enter through hole to coordinate with it, even if on the other hand running into aperture situation less than normal also can realize just location in entering it by deformation, vehicle-mounted power socket behind just location does not haves position skew when welding, simultaneously without artificial by press against, welding operation is more convenient, and it is time saving and energy saving.

Accompanying drawing illustrates: 1, housing；2, metal insert；3, locating dowel；4, fluting；5, joint end；6, upper arch；7, groove；8, chamfering；9, groove is run through.

Detailed description of the invention

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

A kind of vehicle-mounted power socket, including housing 1 and metal insert 2, metal insert 2 one end is positioned at housing 1, and the other end is positioned at outside housing 1 for welding, and housing 1 is provided with locating dowel 3, offers fluting 4 in the middle part of locating dowel 3, and fluting 4 runs through locating dowel 3 sidewall.

By arranging locating dowel 3 on housing 1, therefore in use can realize just location by the through hole of locating dowel 3 with circuit board, and in locating dowel 3, offer fluting 4, and then make locating dowel 3 more possess certain deformability, on the one hand more easily enter through hole to coordinate with it, even if on the other hand running into aperture situation less than normal also can realize just location in entering it by deformation, vehicle-mounted power socket behind just location does not haves position skew when welding, simultaneously without artificial by press against, welding operation is more convenient, and time saving and energy saving.

Locating dowel 3 is provided with joint end 5 away from one end of housing 1, and the width of joint end 5 is more than the width of locating dowel 3.

And joint end 5 is pyramidal structure, width self-align post 3 to the other end of joint end 5 gradually decreases.

By so arranging, in the end of locating dowel 3, joint end 5 is set, and then when just positioning, incessantly it is positioned in circuit board, and joint end 5 passes through hole, then it can strut in elastic restoring force, it is connected on circuit board end face, so make housing 1 also can realize location along locating dowel 3 axis direction, housing 1 is realized fixing by locating dowel 3 and circuit board, and then stability is more significantly, and basic circuit plate is vertical direction placement, still it is capable of well being subjected to, more practicality.

Housing 1 is provided with arch 6, and upper arch 6 sidewall is provided with groove 7.

By arranging arch 6 on housing 1, then only the protuberance coordinated with upper arch 6 need to be set on plug connector equally, both are capable of the spacing of left and right directions after coordinating, simultaneously because the cavity for grafting is also realization of loosing core when plastic shaping in housing 1, by arranging groove 7 in upper arch 6, it is capable of cavity and outside connection, and then is more prone to during molding is loosed core, it is to avoid be internally formed the situation appearance that vacuum is difficult to loose core.

Both sides, metal insert 2 end are provided with chamfering 8, be provided with and run through groove 9 in the middle part of metal insert 2 end.

When by metal insert 2 with welding circuit board; the slot corresponding with inserted sheet would generally be set at circuit board; sheet metal end sections is made to enter in slot, it is simple to welding operation, by arranging chamfering 8 in both sides, metal insert 2 end; workman's metal insert 2 in placement process more easily enters in slot; more convenient to operate, by running through the setting of groove 9, in welding process, welding fluid can enter partly into and run through in groove 9; and then increase bonding area so that the stability of welding is more significantly.

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.
