Specific embodiment
In the present invention, in the case where being not specifically noted, the noun of locality used such as " upper and lower, left and right " is typically referred to
With reference to upper and lower, left and right shown in the drawings；" inside and outside " refers to the inside and outside of the profile relative to each component itself.
As shown in Figure 7, a kind of ground structure of preferred embodiment according to the present invention includes ground terminal 1, ground connection
Ontology 2, and sequentially pass through ground connection ontology 2 and ground terminal 1 and the screw 3 being spirally connected with ground terminal 1.
Wherein, screw 3 is generally included against the nut 30 of ground connection ontology 2 and for across ground connection ontology 2 and with outer
The screw rod 31 of screw thread.To be grounded this since the nut 30 of ground terminal 1 and screw 3 is connected as bearing against by the present invention
The two sides of body 2 can save the components such as nut, and using nut 30 and can be grounded ontology 2 during attachment screw 3
It rubs and removes surface covering, convenient for improving production efficiency, saving material cost.
As shown in Figure 3, above-mentioned ground terminal 1 may include the connecting pin 10, Yi Jijuan being electrically connected with ground connection ontology 2
Around the exit 11 for being connected with ground wire 4.The first flanging bore 102, the free end of first flanging bore 102 are formed on connecting pin 10
Extend away from ground connection ontology 2, and screw thread 101 can be set on the inner hole wall of the first flanging bore 102.Normally, ground terminal 1
Connecting pin 10 and exit 11 have lesser thickness, so as to be arranged winding ground wire 4 structure etc..In this case, traditional
The ground terminal 1 of structure can not substitute nut attachment screw 3 as described above.The present invention on ground terminal 1 by being arranged
First flanging bore 102 enhances effective connection with screw 3, opposite with the nut 30 of screw 3 thus, it is possible to be disposed at
Side enables nut 30 directly to contact simultaneously friction grounding ontology 2.
It should be pointed out that screw thread 101 is not limited in advance, this one kind of tapping adds on the inner hole wall of the first flanging bore 102
Work form can also utilize screw rod 31 by the way that screw 3 is selected as tapping screw in tapping screw precession installation process as a result,
With the relative rotation of the inner hole wall of the first flanging bore 102, screw thread 101 can be formed on the inner hole wall of the first flanging bore 102.
For convenient for screw 3 is connected to ground terminal 1, one end of the direction ground connection ontology 2 of the first flanging bore 102 is also set up
There is inner chamfer 104.
The side against ground connection ontology 2 of connecting pin 10 is equipped with protrusion 100, and the quantity of protrusion 100 is not limited to Fig. 3 extremely
Four shown in Fig. 5, quantity can be one or more, and each raised 100 around the circle for being set to the first flanging bore 102
Circumferential direction, and be arranged in the direction around the first flanging bore 102 from down to high dip, in this way, the extending end of protrusion 100 is formed
There is the seamed edge 103 for being resisted against ground connection ontology 2.As a result, when ground terminal 1 is connected to ground connection ontology 2, seamed edge 103 can
By compressive deformation, the axial pretightning force of the first flanging bore 102 can be generated, to prevent screw 3 from loosening.In this case, may be used
To save spring washer, it is further reduced required part.
Also, form is preferably implemented as one kind, protrusion 100 should be arranged in the neighboring of connecting pin 10.Connecting pin
It is provided with the first flanging bore 102 on 10, protrusion 100 is arranged in neighboring, protrusion 100 can be made to be arranged as with bigger
Size, thus, it is possible to provide larger elastic force and by compressive deformation, substitution spring washer generates preload effect.
Preferably, as shown in Figure 6, it is grounded on ontology 2 and the side that ground terminal 1 is arranged is provided with the second flanging bore
20.In conjunction with Fig. 6 and Fig. 7, (free end herein is interpreted as the end of the flange of the second flanging bore 20 for the free end of the second flanging bore 20
End) away from the link position setting of ground terminal 1.The downside of nut 30 is enabled in screw 3 and 1 connection procedure of ground terminal
The flange upper end of the second flanging bore 20 of face friction, thus removes removing coating, is easy to implement between ground terminal 1 and ground connection ontology 3
Electrical connection.
Ground connection ontology 2 can be the metal shell of the household electrical appliance such as galvanized sheet one kind, will such as the metal shell of micro-wave oven
The ground structure of the present embodiment description is used in the metal shell of household electrical appliance, can reduce zero of the ground structure of metal shell
Number of packages amount.Also, during rotation screw 3 is spirally connected to it with the screw thread 103 on ground terminal 1, the friction of nut 30 second is turned over
Lateral opening 20 top edge, this process are similar to the removing coating operation on metal shell.It should be understood that although being stated upper
It is mainly described in bright with being grounded ontology in connection status, but ground structure of the invention can be unassembled loose mail shape
State belongs to protection of the invention as long as its each section can correspond to each technical characteristic that technical solution of the present invention limits
Range.
In addition, the present invention also provides a kind of household electrical appliance, such as micro-wave oven, the household electrical appliance have on provided by the invention
State ground structure.
It is described the prefered embodiments of the present invention in detail above in conjunction with attached drawing, still, the present invention is not limited thereto.At this
It, can be with various simple variants of the technical solution of the present invention are made in the range of the technology design of invention.But these simple variants and
It should also be regarded as the disclosure of the present invention for combination, all belongs to the scope of protection of the present invention.
