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 insert 2, metal insert 2 one end is positioned at housing 1, and it is outer for welding that the other end is positioned at housing 1, and housing 1 is provided with locating dowel 3, and locating dowel 3 sidewall is evenly distributed with fin 4 thus forming cross locating dowel 3.

By arranging locating dowel 3 on housing 1, therefore in use can pass through locating dowel 3 and realize first location with the through hole of circuit board, and the sidewall of this locating dowel 3 is provided with fin 4 and forms cross locating dowel 3, more than horizontal linear direction is capable of spacing, and circumference also can realize spacing, cross structure also can increase contact area greatly simultaneously, increasing friction force, the first location making housing 1 is more stable, vehicle-mounted power socket behind just location does not have position skew when welding, simultaneously without artificial by press against, welding operation is more convenient, and it is time saving and energy saving.

And the top of wherein fin 4 is equipped with radius 5, radius 5 can play good importing effect when cross locating dowel 3 inserts the through hole of circuit board so that the end of cross locating dowel 3 is more prone to aligned through holes and enters through hole, and alignment function is more laborsaving.

Further, housing 1 side is provided with inserting groove 7, and inserting groove 7 is internal is provided with clamping block 6, and clamping block 6 height is gradually increased to opposite side from inserting groove 7 opening.

By so arranging the inclined-plane making clamping block 6 upper surface have importing, only need at the groove with setting on the plug connector of inserting groove 7 grafting with clamping block 6 clamping, therefore when plug connector inserts in inserting groove 7, first pass around the deformation of the guiding on clamping block 6 to slip into, move to groove and clamping block 6 to the time in of corresponding plug connector recovers under restoring force effect and then realizes buckling, and then plug connector cannot occur from the situation that inserting groove 7 is deviate from, and connects more firm.

Inserting groove 7 inwall is provided with the gathering sill 8 of strip, gathering sill 8 can play guide effect, the sliver coordinated with gathering sill 8 only need to be set on plug connector, so plug connector when grafting can more precisely with metal insert 2 grafting, it is to avoid the situation appearance not being directed at slotting askew metal insert 2.

Further, the diapire of inserting groove 7 is provided with through groove 9.

It is capable of, by running through the setting of groove 9, the connection that inserting groove 7 is internal with outside, and then is more prone in process is loosed core in molding, 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 10, and metal insert 2 is provided with groove 11 in the middle part of 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 10 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 the setting of groove 11, in welding process, welding fluid can enter partly in groove 11; 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.
