Abstract

The utility model relates to an automobile power supply converter, which comprises a square casing, wherein a circuit board, a transformer and an aluminum case thereof are arranged in the square casing, the left side and the right side of the casing are communicated, the square casing consists of a bottom wall, an upper wall, a front side wall and a back side wall which are formed into a whole body, a plurality of heat radiation grooves with the communicated left and right sides are arranged on the outer surfaces of the upper wall, the front side wall and the back side wall, the bottom wall extends towards the left side and the right side, an installation seat hole is arranged on the extending end, a flat-plate-shaped sealing plate is respectively arranged at both ends of the casing, and the sealing plates are fixedly connected with the end surfaces of the upper wall, the front side wall and the back side wall of the casing. The installation seat hole in the utility model is arranged on the bottom wall which is formed into the whole body with the upper wall, and the front side wall and the back side wall of the casing, the sealing plates are in independent flat plate shapes, so the installing seat hole with the installation fixation effect and installation screw holes of the sealing plates with the opening sealing effect become independent, and the vibration at the installation seat hole can not influence the installation fastness of the sealing plates. Thereby, the use safety of the power supply converter can be ensured.

Description

The automobile power source transducer

Technical field:

The utility model relates to a kind of power supply changeover device, particularly a kind of automobile power source transducer.

Background technology:

The housing of automobile power source transducer generally all is to adopt aluminum alloy materials to make.In order to cut down finished cost, commonplace is to adopt drawing process to process the box-shaped aluminum hull of two break-through, the wiring board that electric elements will be installed then is nested with behind square aluminum hull internal fixation, two ends are fixed with the sealing cover of square bending again, this sealing cover is to be installed on the both ends of the surface of aluminum hull by screw, also being provided with installing hole on the bottom surface of sealing cover is used for this transducer is installed in automobile, because the wall thickness of aluminum hull is limited, therefore its size of mounting screw of sealing cover and aluminum hull is also less, the intensity of installing is also very limited, so in use occur waving, during the vibration situation, thereby the vibration in mount pad hole can directly cause the vibration of the mounting screw of sealing cover and aluminum hull its easy pine is unloaded, therefore can cause sealing cover and aluminum hull to break away from, cause potential safety hazard.

The utility model content:

The purpose of this utility model provides a kind of automobile power source transducer reliable, that cost is also low that uses.

The utility model is realized above-mentioned purpose of the present utility model by following technical solution: a kind of automobile power source transducer, include square casing, wiring board is installed in square casing, transformer and aluminum hull thereof, the left side of this housing, right both sides communicate, this square casing by constitute one diapire, upper wall and before, rear wall constitutes, before upper wall reaches, respectively be provided with many left sides on the outer surface of rear wall, the radiating groove that the right side communicates, it is characterized in that: described diapire left, extend right both sides, on elongated end, be provided with the mount pad hole, two ends at housing respectively are provided with the tabular shrouding, this shrouding by screw and housing upper wall and before, the end face of rear wall is fixedly connected.

Described transformer is encapsulated in the aluminum hull with heat-conducting glue, and aluminum hull is sticked by screw and is fixed on the upper wall.。

Mount pad hole on the elongated end of described each side is 2, and this mount pad hole is a U-shaped, and its openend is respectively towards front and rear direction.

The utlity model has following beneficial effect: the mount pad hole in the utility model is arranged on the diapire with the upper wall of housing and forward and backward sidewall one, shrouding then is tabular independently, the mount pad hole of working the effect of installing and fixing like this is just independent with the installation screw of the shrouding that works the effect of sealing, the vibration that place, dress hole is installed just can not influence the installation tightness of shrouding, thereby guarantees the safe in utilization of power supply changeover device.

Description of drawings:

Fig. 1 is the structural representation of the embodiment of a kind of automobile power source transducer of the utility model.

Fig. 2 is the explosive view of the embodiment of a kind of automobile power source transducer of the utility model

Embodiment:

The utility model is described in further detail below in conjunction with accompanying drawing:

By Fig. 1, shown in 2, the embodiment of a kind of automobile power source transducer of the utility model, include square casing 1, wiring board 6 is installed in square casing 1, transformer and aluminum hull 2 thereof, the left side of this housing 1, right both sides communicate, this square casing by constitute one diapire 11, upper wall 12 and before, rear wall 13,14 constitute, before upper wall 12 reaches, rear wall 13, respectively be provided with many left sides on 14 the outer surface, the radiating groove 3 that the right side communicates, described diapire 11 left, extend right both sides, on elongated end 111, be provided with mount pad hole 1111, mount pad hole 1111 on the elongated end 111 of each side is 2, this mount pad hole 1111 is a U-shaped, and its openend is respectively towards preceding, the rear to.

In the present embodiment, described transformer is encapsulated in the aluminum hull 2 with heat-conducting glue, and aluminum hull 2 is sticked by screw 5 and is fixed on the upper wall 12.Aluminum hull 2 is sticked and is fixed on the upper wall 12, and the heat of transformer 2 can distribute from aluminum hull and housing fast in the use, thereby helps improving the serviceability of transformer.

In the diagram, respectively be provided with tabular shrouding 4 at the two ends of housing 1, this shrouding 4 is fixedlyed connected with the upper wall 12 of housing 1 and the end face of forward and backward sidewall 13,14 by screw 5.

The utility model is in the course of processing, utilize the stretched square casing 1 of drawing process earlier, at this moment a housing left side, right both sides are flat mouth, and then with the left side of housing 11, the part at right two ends is carried out Milling Process to the bottom surface, bottom surface under this is remaining promptly constitutes elongated end 111, and then on the bottom surface, mill out mount pad hole 1111, stretch to wiring board 6 after housing 1 inner chamber is screwed installation by left side or right side this moment, seal at the two ends that are installed in housing 1 with flat shrouding 4 again, just can realize the processing of power supply changeover device, the device program, since mount pad hole 1111 be arranged on the upper wall 12 of housing 1 and before, rear wall 13, on the diapire 11 of 14 one, shrouding 4 then is tabular independently, the mount pad hole 1111 of working the effect of installing and fixing like this is just independent with the installation screw 5 of the shrouding 4 that works the effect of sealing, the vibration that place, dress hole is installed just can not influence the installation tightness of shrouding 4, thereby guarantee the safe in utilization of power supply changeover device, and the housing cost that the mode of employing cold stretch is processed is low, good looking appearance.
