The following text will describe a ground wire installation structure in conjunction with the drawings of the specification.
Referring to fig. 1 and 2, in some embodiments, the ground wire mounting structure 10 includes a ground terminal 100, a mounting element 200, and a connecting element. It should be noted that the terms "ground wire mounting structure", "ground terminal hole", and "ground wire mounting hole" in the present invention do not necessarily have to have a ground wire present. It is understood that "ground wire mounting structure" and "ground wire terminal" are only provided with a mounting structure that can be used for mounting a ground wire without a ground wire, or only provided with a terminal that can be used for realizing electrical connection of a ground wire without a ground wire, and the present invention is also within the protection scope of the present invention.
The ground terminal 100 includes a fixing portion 110 and a crimping portion 120, the fixing portion 110 has a ground terminal hole 130, and the crimping portion 120 extends from one end of the fixing portion 110 to a direction away from the ground terminal hole 130. The crimping portion is arranged to arrange and fix the ground wire on the ground wire terminal, and the fixing portion is arranged to mount the ground wire terminal on the corresponding mounting element.
Specifically, as shown in fig. 1 and 2, the fixing portion 110 has a circular ring shape, and the center of the circular ring is the ground terminal hole 130, that is, the ground terminal hole 130 is also circular. The ground terminal hole 130 is a through hole; the crimping part 120 extends from one side of the fixing part 110 to a direction away from the ground terminal hole 130, the crimping part 120 is cylindrical, or the cross section of the crimping part 120 is C-shaped (the ground may be wrapped by the C-shaped crimping part 120), or the crimping part 120 is long. Fig. 1 shows that the surface of the crimping portion 120 is approximately flush with the surface of the fixing portion 110. The fixing portion 110 is used for electrical connection with a ground wire (not shown in the drawings), and the crimping portion 120 is used for press-fixing the ground wire to the crimping portion 120 after being press-deformed, thereby achieving crimping of the ground wire.
It is understood that, in order to electrically connect the ground terminal 100 to the ground wire, the ground terminal 100 may be made of a material having a conductive property, such as a metal material.
Specifically, the mounting member 200 is a metal plate member, and the ground wire mounting hole 210 is a screw hole. The mounting element is provided with a ground wire identification 240. The connecting element can be a threaded connecting element such as a screw. The threaded connection element passes through the ground terminal aperture 130 and the ground mounting aperture 210 in sequence and forms a threaded connection with the ground mounting aperture 210. The ground terminal 100 is mounted to the mounting member 200 by tightening the threaded connection member. It is understood that the aperture of the ground terminal hole 130 is not smaller than the aperture of the ground mounting hole 210. Since the outer diameter of the screw-coupling member is substantially equal to the inner diameter of the ground mounting hole 210, in order to ensure that the screw-coupling member can pass through the ground terminal hole 130 and the ground mounting hole 210, the design should ensure that: the aperture of the ground terminal hole 130 is not smaller than the aperture of the ground mounting hole 210.
Fig. 1 also shows that the mounting element 200 is provided with a positioning hole 220, and the ground terminal 100 is provided with a positioning member 140, wherein the positioning member 140 can extend into the positioning hole 220.
After the positioning piece extends into the positioning hole, the relative position relationship between the ground terminal and the mounting element is basically fixed. The ground terminal hole is positioned on the ground terminal and the ground terminal hole is positioned on the mounting element, so that the relative position relationship between the ground terminal hole and the ground mounting hole is also determined, the ground terminal hole and the ground terminal hole are conveniently aligned, and the assembly operation efficiency is improved.
Specifically, the positioning hole 220 is an elongated through hole. It is understood that the positioning hole 220 may be selected from a circular hole or a polygonal hole (including a triangular hole) as desired. The shape of the positioning member 140 is not limited, and it is sufficient to ensure that it can be inserted into the positioning hole 220 to position the ground terminal with respect to the mounting member.
Fig. 1 also shows that in some embodiments, the positioning member 140 is integrally formed with the ground terminal 100, and the positioning member 140 is formed by bending a portion of the ground terminal 100. The positioning piece and the ground terminal are integrally formed, so that parts do not need to be additionally arranged as the positioning piece, and the number of the parts is reduced.
Specifically, the positioning element 140 is formed by bending and extending one side of the fixing portion 110 (the direction shown in fig. 1 is downward), and the bending angle is 90 °. Other angles of bending may be selected as desired. It is understood that the positioning member 140 may also be formed by extending one side of the fixing portion 110 along a direction substantially parallel to the axis of the ground terminal hole 130, or by extending one side of the fixing portion 110 along a direction forming an angle with the axis. It is understood that the positioning member 140 may also be formed by bending and extending one side of the crimping portion 120, and the positioning member 140 may also be formed by extending one side of the crimping portion 120 in a direction substantially parallel to the axial direction of the ground terminal hole 130 or in a direction forming an angle with the axial direction.
In some embodiments, the positioning member 140 is a separate element that is removably mounted to the ground terminal 100. After the ground terminal hole is aligned with the ground terminal hole, the positioning piece can be detached, and the compactness of the whole ground wire mounting structure and the relative flatness of the surface are kept.
Referring to fig. 3 and 4, in some embodiments, the mounting element 200 is further provided with a stop 230, the stop 230 protrudes from a surface of the mounting element 200, and the stop 230 is located at a position such that the stop 230 can prevent the ground terminal 100 from rotating in a screwing direction of the connecting element.
During the assembly operation of the fixed ground wire, screwing the connecting element will often cause the ground terminal 100 to rotate as well, i.e. the ground terminal 100 is caused to rotate in the direction in which the connecting element is screwed. Such a wire terminal 100 will rotate the ground wire, causing the ground wire to be pulled and thus easily damaged. Furthermore, the pulled ground wire may cut the worker. The stop prevents the ground terminal from rotating in the direction in which the connecting element is screwed, so that the ground wire is not pulled during the assembly operation of the fixed ground wire.
In particular, the coupling element is a right-hand threaded coupling element, whereby a clockwise rotation of the threaded coupling element causes it to be screwed. The stopper 230 is located at a position such that the stopper 230 can prevent the ground terminal 100 from rotating in the clockwise direction.
Referring to fig. 3 and 4, the stopper 230 is closer to the pressing portion 120 than to the fixing portion 110. The pressing portion 120 is elongated as a whole, similar to the arm of the lever principle, so that the stopper 230 prevents the pressing portion 120 from rotating in the direction of screwing the connecting element, which is more effective. It is understood that the stopper 230 may be closer to the fixing portion 110. The outline of the fixing portion 110 is circular. The circular shape is relatively smooth relative to other shapes and thus may be somewhat less effective in resisting rotation than other shapes. For this, a shape, such as a convex shape or a concave shape, etc., which is matched with the stopper 230 may be provided on the fixing part 110 to overcome the defect that the circular profile is not easily stopped. Of course, the fixing portion 110 is not provided with a shape matching with the stopper 230, and may also function to prevent rotation to some extent. Therefore, the shape of the fixing portion 110 that fits the stopper 230 is not limited.
It should be noted that fig. 3 and 4 do not show the positioning member 140 and the positioning hole 220 in fig. 1 and 2, but this does not mean: the positioning member 140 and the positioning hole 220 shown in fig. 1 and 2 cannot coexist with the stopper 230 shown in fig. 3 and 4. According to the needs, in some embodiments, there may be both the positioning member 140 and the positioning hole 220, and also the stop member 230, so as to solve the problem of how to align the ground terminal hole and the ground mounting hole conveniently, and how to prevent the ground terminal from being rotated synchronously by the rotation of the connecting element.
In some embodiments, stop 230 is a raised structure stamped from mounting member 200. The mounting elements are often formed from sheet metal and are easily stamped. The convex structure is formed by adopting a stamping process, the process is simple, and additional processing equipment is not required.
Referring to fig. 3 and 4, in some embodiments, the convex surface of the convex structure is a curved surface, and one side of the convex structure is a straight surface. As previously mentioned, round, spherical, and other curved shapes do not have the same blocking effect as non-curved shapes. One side of the convex structure is a straight surface, so that the effect of preventing the ground wire terminal from synchronously rotating is better; the convex structure with the curved surface can reduce stress concentration, so that the mechanical property is not deteriorated.
Specifically, as shown in FIG. 3, on a side generally located in the front-right direction of the projection structure is a straight side 234. The convex surface of the convex structure interfaces with the surface of the mounting element 200 to form a first profile 231 of the convex structure, the first profile 231 being substantially parabolic when viewed from a top view. The straight side 234 of the raised structure interfaces with the surface of the mounting element 200 to form a second profile 232 of the raised structure, the second profile 232 being substantially linear when viewed from above. The second profile 232 substantially closes off the parabolic opening of the first profile 231. Fig. 3 also shows that the straight side 234 of the protruding structure has a notch, the profile of which is a third profile 233, the third profile 233 also being dome-shaped or parabolic. The raised structures are raised relative to the surface of the mounting element 200, with indentations being formed on the straight sides 234 of the raised structures.
In some embodiments, the raised structure is formed by bending a portion of the mounting element 200 away from the surface of the mounting element 200. After a part of area of the mounting element is punched, the mounting element in the area is obliquely erected or vertically erected, a hole is formed in the surface of the mounting element, the obliquely erected or vertically erected mounting element part is not separated from the original mounting element only at the bottom, and the obliquely erected or vertically erected mounting element part forms a protruding structure. The raised structure formed in this way has better effect of preventing the ground wire terminal from synchronously rotating due to the inclined straight surface or the vertical straight surface.
In some embodiments, stop 230 is removably attached to mounting member 200. After the assembly work of the fixed ground wire is completed, the stopper can be removed, thereby keeping the compactness of the whole ground wire installation structure and the relative flatness of the surface.
A second aspect of the embodiments of the present invention provides an air conditioner. The air conditioner has the ground wire mounting structure in any one of the aspects of the embodiment of the first aspect described above, and the ground wire 20 is electrically connected to the ground terminal 100. The air conditioner is used as a high-power household appliance, a shell of the air conditioner is possibly charged with certain static electricity due to poor insulating performance or moisture in a use environment, and an electric shock accident of the air conditioner can happen in severe cases. One end of the grounding wire of the air conditioner is connected to the ground, and once the air conditioner leaks electricity, the grounding wire brings static electricity into the ground to be released, so that the occurrence of electric leakage accidents is effectively reduced.
Obviously, the air conditioner has the beneficial effects corresponding to the ground wire installation structure of any one of the above technical solutions, and the details are not repeated herein.
In some embodiments, at least one of the outdoor unit middle partition plate assembly, the outdoor unit terminal mounting plate assembly and the indoor unit evaporator sheet metal end plate assembly of the air conditioner is provided with a ground wire mounting structure.
