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
Upper and lower, left and right shown in refer to the attached drawing；" inside and outside " refers to the inside and outside of the profile relative to each part in itself.
As shown in Figure 7, according to a kind of ground structure of preferred embodiment of the invention, ground terminal 1, ground connection are included
Body 2, and sequentially pass through ground connection body 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 body 2 and for through ground connection body 2 and with outer
The screw rod 31 of screw thread.So as to because the nut 30 of ground terminal 1 and screw 3 is connected as bearing against in ground connection originally by the present invention
The both sides of body 2, can save the parts such as nut, and can be using nut 30 with being grounded body 2 during attachment screw 3
Rub and remove face coat, be easy to improve production efficiency, save material cost.
As shown in Figure 3, above-mentioned ground terminal 1 can include the connection end 10, Yi Jijuan electrically connected with ground connection body 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 with connection end 10
Extend away from ground connection body 2, and screw thread 101 can be provided with the inner hole wall of the first flanging bore 102.Normally, ground terminal 1
Connection end 10 and exit 11 there is less thickness, to set structure etc. of winding ground wire 4.In this case, it is 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 setting
First flanging bore 102, enhances effective connection with screw 3, relative with the nut 30 of screw 3 thus, it is possible to be disposed at
Side so that nut 30 can be contacted directly and friction grounding body 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 electing screw 3 as tapping screw, thus in tapping screw precession installation process
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 ease of screw 3 is connected into ground terminal 1, one end of the direction ground connection body 2 of the first flanging bore 102 is also set up
There is interior chamfering 104.
The side against ground connection body 2 of connection end 10 is provided with projection 100, and the quantity of projection 100 is not limited to Fig. 3 extremely
Four shown in Fig. 5, its quantity can be one or more, and each projection 100 is around the circle for being arranged at the first flanging bore 102
Circumferential direction, and set in the direction around the first flanging bore 102 from as little as high dip, in this way, the extending end of projection 100 is formed
There is the seamed edge 103 for being resisted against ground connection body 2.Thus, when ground terminal 1 is connected into ground connection body 2, its seamed edge 103 can
By compression, the pretightning force of the axial direction of the first flanging bore 102 can be produced, so as to prevent screw 3 from loosening.In this case, may be used
To save spring washer, part needed for further reducing.
Also, form is preferably implemented as one kind, projection 100 should be arranged in the neighboring of connection end 10.Connection end
The first flanging bore 102 is provided with 10, projection 100 is arranged in neighboring, projection 100 can be made to be arranged as with bigger
Size, thus, it is possible to by being provided larger elastic force by compression, substitute spring washer and produce pretension effect.
Preferably, as shown in Figure 6, the side that dorsad ground terminal 1 is set on ground connection body 2 is provided with the second flanging bore
20.With reference to 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.Screw 3 and the downside that nut 30 is enabled in the connection procedure of ground terminal 1
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 body 3
Electrical connection.
Ground connection body 2 can be the metal shell of the household electrical appliance such as the class of galvanized sheet one, and the metal shell of such as micro-wave oven will
The ground structure of the present embodiment description is used in the metal shell of household electrical appliance, you can reduce the ground structure of metal shell zero
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 is similar to the removing coating operation on metal shell.Although it should be appreciated that being stated upper
Mainly it is described in bright with being grounded body in connection status, but the ground structure of the present invention can be unassembled loose mail shape
State, as long as its each several part can correspond to each technical characteristic that technical solution of the present invention is limited, belongs to the protection of the present invention
Scope.
In addition, the present invention a kind of household electrical appliance, such as micro-wave oven are also provided, the household electrical appliance have the present invention provide it is upper
State ground structure.
The preferred embodiment of the present invention is described in detail above in association with accompanying drawing, still, the present invention is not limited thereto.At this
In the range of the technology design of invention, a variety of simple variants can be carried out to technical scheme.But these simple variants and
Combination should equally be considered as content disclosed in this invention, belong to protection scope of the present invention.
