Abstract

The present invention provides a fuel transporter having a drive motor (16), which is installed in a metal shell (20) and having a grounding line (38) of the motor. The grounding line (38) connects to the shell (20) by a contact member (42). The contact member (42) is designed to be ring shape, and surrounding at least a part of the shell (20). The contact (42) is fixed on the outside of the contact (42), and glues to the shell (20) at least along a part of the circumference. Thus, the contact member (42) can conveniently be arranged on the shell (20), and activates the shell (20) contact to the grounding line (38) by great area, thus the drive motor (16) has excellent anti-jamming ability.

Description

Fuel hauling equipment

The present invention relates to a kind of fuel hauling equipment by the described type of claim 1.

By known this class A fuel A conveying equipment of DE-U9200625.This fuel hauling equipment has a pump and a drive motor, and the ground wire that has a drive motor at least.Ground wire is communicated with a joint contact of fuel hauling equipment, and joint has a contact, and contact abuts on the casing made from conductive material.Require fuel hauling equipment and casing that special structure is arranged in this case, so as ground wire can fuel hauling equipment inner with the casing contacting, and this contacting must have been finished when the assembling fuel hauling equipment.In addition, this contact only has the contacting of small size with casing, and therefore drive motor does not have enough antijamming capabilities in some cases.

Has fuel hauling equipment by the present invention by the described feature of claim 1, such advantage is arranged by contrast, that is, contact can be with simple method, need not fuel hauling equipment and special structure is arranged and after fuel hauling equipment assembling, also it can be installed on its casing.

Illustrated in the dependent claims by the design of fuel hauling equipment of the present invention and further improvement.By the described design of claim 2 contact is reclined along bigger area, thereby can make drive motor obtain enough antijamming capabilities.Can easily contact be fixed on the casing by the described design of claim 5, need not casing and have special fastening piece.

Represented two kinds of embodiments of the present invention in the accompanying drawings, and described in detail in the following description.

Fig. 1 perspective representation fuel hauling equipment;

Fig. 2 is at the fuel hauling equipment that has along expression in the cross section of the line II-II among Fig. 1 by first kind of embodiment's contact;

Fig. 3 represents to have the fuel hauling equipment of modified contact form of implementation in cross section; And,

Fig. 4 represents to have the fuel hauling equipment by second kind of embodiment's contact in cross section.

The fuel hauling equipment 10 of expression is used for from the internal-combustion engine transfer the fuel of fuel reserve tank to automobile in Fig. 1 to 4.This fuel hauling equipment 10 for example is contained in the dust collector 12 that is located in the fuel reserve tank as shown in Figure 1, and from the fuel reserve tank suction of fuel.This fuel hauling equipment 10 has a pump 14 and a drive motor 16, and they are contained in the public casing 18, and casing 18 is local at least to be made with conductive material especially metal.Casing 18 for example can have the part casing 20 of a tubulose, and it is made with conductive material especially metal, and each seals with a

lid

22 or 24 at its two ends.Wherein, lid 22 is at that end sealing casing 20 at pump 14 places.

Lid 24 is at drive motor 16 place end sealing casings 20.Lid 24 for example can be by the plastics manufacturing, and is provided with a pressure tap 26 on lid 24, is discharged from fuel hauling equipment 10 by pressure tap 26 by the fuel that pump 14 is carried, and arrives internal-combustion engines through fuel pipe 28.In addition, also be provided with two

electrical connectors

30,32 on lid 24, they are connected with the brush of drive motor 16.

Joint

30,32 can for example be designed to latch, and plug 34 can be inserted on the latch, and

elastic cable paper

36,38 is connected with plug 34, and

elastic cable paper

36,38 leads to power supply.Wherein, the elastic cable paper 36 that leads to positive source is connected with joint 30, and the elastic cable paper 38 that leads to power cathode that is ground connection is connected with joint 32.

Tell a lead 40 from ground wire 38, it leads to contact 42, and contact 42 is fixed on casing 20 outsides and this casing 20 that reclining.Lead 40 can be connected with ground wire 38 by means of curling connection set 44, or by means of other known link.Lead 40 can have a plug 46 in its end, and it can engage with a plug connector 48 of contact 42.

Shown in Fig. 2 and 3, contact 42 for example can be designed to the ring of a sealing, and it is enclosed within on the casing 20, and thereby round the whole circumference of casing 20.Plug connector 48 is stretched out from contact 42 in a place at its circumference, and it for example can be arranged to generally along tangentially, and can be designed to flat pin.Yet plug connector 48 also can be arranged as other any form, so that the concrete installation conditions of its based on fuel conveying equipment 10 is arranged in the dust collector 12.Contact 42 especially metal manufacturings of usefulness conductive material, and be clamped on the casing 20, so can abut on the outside of casing 20 along its whole circumference.

Contact 42 can be for example as is known cramp frame have one or more like that and as shown in Figure 2 to overhanging projection 50, after being enclosed within contact 42 on the casing 20, can projection be squeezed and close by means of clamp, reduce the girth of contact 42 thus, and contact 42 is clamped on the casing 20.Fuel hauling equipment 10 can be fixed in the dust collector 12 by means of a fixed block 60 as shown in Figure 1, and fixed block 60 for example has an arm 62 that is fixed on fuel hauling equipment 10 casings 18 at least.Contact 42 can be contained on the part casing 20 so in this case, that is, the arm 62 of fixed block 60 passes projection 50.

By another kind of alternative plan, contact 42 also can be designed to the cramp frame of a band screw as shown in Figure 3, wherein be provided with a clamping screw 52, its head rest supporting is on a circumferential end of contact 42, and be screwed in a section of another circumferential end with internal thread, or screwing on a nut 54 that is bearing on another circumferential end on the screw 52.In this case, at first contact 42 has a circumference bigger than casing 20, and it is enclosed within on the casing 20, then, tightens clamping screw 52, the girth of contact 42 is reduced, thereby it is clamped on the casing 20.By another kind and the different scheme of top these forms of implementation, contact 42 also can be the energy elastic dilatation, in its reset condition the girth littler than casing 20 arranged, make it elastic dilatation when being enclosed within contact 42 on the casing 20, the elastic forepressure by contact 42 is fixed on the casing 20.

By be the different scheme of above-mentioned design of the contact 42 of closed loop in form, contact 42 can be second kind of embodiment of a ring section by shown in Figure 4 being designed to also in form, in this case, contact no longer extends along the whole circumference of casing 20, and only extends along the part of circumference.Need only the circumferential extension 1/2nd or more of contact 42 along casing 20 this moment, it just can directly be clamped on the casing 20, and contact itself is fixed on the casing 20 by suitable elastic forepressure in this case.This contact 42 also can be along the circumferential extension of smaller portions of casing 20, and for it is fixed on additional fastening piece 56 can be set also on the casing 20, and it for example can be designed to a clamping ring in form.Contact 42 also can have random appearance, and wherein, contact element surface matches towards that side of casing 20 and the circumference of casing 20, so contact 42 can abut on the casing 20 in large area.

Illustrated in the above by means of clamping connector contact 42 is fixed in the various possibilities on the casing 20, casing 20 itself need not to take any special measure for fixed contact therefor 42.If desired, contact 42 can be contained on the casing 20 afterwards.
