Abstract
The pump has a housing shell (12) with a connecting lid (11). The lid has an earth connection (22) which is electrically connected via a connecting element (43) to the inner wall of the housing shell. The connecting element positively engages in a contact element which is operatively connected to the inner wall of the housing shell. The contact element may be a magnet holder (40) with a contact surface (41) lying on the inner wall of the housing shell. The magnet holder comprises a receptacle (50) which clamps and partially encloses the connecting element.
Description
The present invention relates to a kind of as described in claim 1 preamble and be disclosed in electric fuel pump among the German utility model DE-GM9200625.This electric fuel pump has a shell and a link cover of FIG that links to each other with described shell, and link cover of FIG wherein has a ground wire contact, and it realizes electrically contacting through the inwall of a connecting element and described shell.Known electric fuel pump has the connecting element of a brush shape, and it links to each other with a ground wire contact of electric fuel pump.This outer bruss has the bending of one section correspondence on the wall in the enclosure, so the ground wire contact of shell can be linked to each other with the ground wire contact of electric fuel pump.The shortcoming of this structure is, the part of shell and electric fuel pump must adopt proprietary structure, so that provide corresponding free space for the brush structure on the casing wall.In addition, described connecting element can only be with very little area and housing contacts, so in some cases, the drive motor of electric fuel pump can not reach enough interference characteristics that goes.
The solution of the present invention is, described connecting element is plugged in the contact member with special-shaped Placement, exists between the inwall of this contact member and described shell effectively to be connected.
Described contact member is a magnet fixed block, has a surface of contact that is attached at least in part on the described outer casing inner wall, and described magnet fixed block has that described connecting element partly can be surrounded, as to play a clamping action socket.
Described magnet fixed block is made with thin plate, and described socket and magnet fixed block adopt deformation technique to make an integral body.
Described socket has surface of contact in a side that is positioned at the outer casing inner wall opposite, and its end position is roughly concordant with the end face of magnet fixed block on the opposite of described link cover of FIG.
Described connecting element is an arc lead.
According to the present invention, the advantage with electric fuel pump of the described structure of claim 1 characteristic is that the surface of contact that the ground wire between its connecting element and the shell connects is bigger, and reliable.This connection is to set up in the assembly technology of link cover of FIG and shell.
The further improvement of electric fuel pump of the present invention embodies in the dependent claims.
Particularly advantageous is that described contact member is a magnet fixed block, is attached on the inwall because its structure can guarantee a surface of contact.Be integrated in the magnet fixed block in relative simple mode with the socket of described connecting element contact in addition.A kind of simple especially mode of making socket is that described socket is the constituent element of magnet fixed block, and fuses with the latter.
The present invention is further illustrated for contrast accompanying drawing illustrated embodiment below.
Fig. 1 represents the local longitudinal sectional view of electric fuel pump,
Fig. 2 represents the cross-sectional view of electric fuel pump shown in Figure 1 in shell/ground wire contact segment.
In Fig. 1, electric fuel pump represents that with label 10 it is a constituent element of fuel for motor vehicle ejecting system.This electric fuel pump 10 has a link cover of FIG 11, it be essentially columnar shell 12 and be tightly connected.The sealing connection is to be inserted in shell 12 by the link cover of FIG 11 that is positioned at shell edge 13 opposites to realize, and fixes by 14 crimpings of the inclined-plane on the link cover of FIG linkage section 16.
The preferred plastics that adopt have-individual pressure tube 17 by the link cover of FIG 11 of injection technique manufacturing, and the inside is integrated with a safety check 18, by this valve, are in pressure under and are sent along the vertically mobile fuel of described electric fuel pump 10.Being parallel to pressure tube is a connector socket 19, is used for armature 20 the electrically contacting in link cover of FIG 11 in the shell 12.Connector socket contact 22 is arranged in connector socket 19, and it passes link cover of FIG 11, only can see a connector socket contact 22 in Fig. 1, and it links to each other with ground wire on the motor circuit.An arcuate segment 23 of described connector socket contact 22 is realized being electrically connected by a unillustrated lead and armature winding.This arcuate segment 23 leans against on a bearing and the bearing support 25, and the latter has a hole 26 to be used to hold the sliding bearing 27 of armature shaft 28.Described in addition bearing and bearing support 25 also have a through hole 29 of aiming at pressure tube 17, be used to the fuel that circulates, and the supporting surface 31 of a flange shape, it has correct axial position so can guarantee link cover of FIG 11 on shell 12 between an end face of the convex shoulder 32 of shell 12 and link cover of FIG 11.
On the height of the cylindrical intermediate section 34 of armature 20, on the inwall 35 of shell 12, be provided with a bar magnet 36 (Fig. 2).The cross section of this magnet 36 has the side 37 of two broads that are parallel to each other respectively, and two narrower sides 38 are arranged on its relative surface of contact, and they have the radius that the diameter with shell 12 is complementary, and have corresponding inclined-plane.Be the position of fixed magnet 36, on the inwall 35 of shell 12, be provided with a magnet fixed block 40.
In punching press/deformation technique, the magnet fixed block made from thin plate 40 is close on the curved shape surface of contact 41 on the inwall 35, and two effects have prestressed sector hypotenuse 42, they lean against respectively on the narrow side 38 of magnet 36, under its prestressed effect, magnet 36 radially is fixed on the inwall 35 of shell 12.
The above electric fuel pump 10 and function thereof all are known.Internal of the present invention improves the special contact structures that are between shell 12 and ground wire or the corresponding connector socket contact 22.For this reason, described electric fuel pump 10 has an arc connecting element 43, and it has-the individual vertical also contact-segment 46 of bending with of introducing section 45 that is parallel to longitudinal axis 44 extensions of electric fuel pump 10.The connecting element 43 of arc wire shape has the rectangular cross-section, and makes according to its shape bending with the lead bar of a respective length.The contact-segment 46 of described connecting element 43 realizes electrically contacting with the connector socket contact of ground connection 22.Stretch out from link cover of FIG 11 end 47 that is arranged in armature 20 opposites of contact-segment 46, and be inserted in this magnet fixed block 40 on the height of the magnet fixed block 40 in shell 12.Be inserted in the magnet fixed block 40 and the termination 48 of coupled contact-segment 46, its cross section has a little to dwindle, and at its front end the inclined-plane 49 of insertion is arranged.Realized with being connected by the cover 50 of pegging graft of magnet fixed block 40 termination 48.This grafting cover is that the segmentation 51 by magnet fixed block 40 forms, and its local punching press on surface of contact 41 forms, and is deformed or bends to peg graft and overlap 50.This grafting cover 50 is parts of magnet fixed block 40, and fuses with the latter.This grafting cover 50 has constituted the socket 52 of the termination 48 of connecting element 43, and the latter is clamped.
