Technical Field
[0001] This invention relates to the field of wire cutting equipment technology, and more specifically, to a wire sheath cutting device and a wire sheath cutting method. Background Technology
[0002] A conductor consists of a sheath and the conductor inside the sheath. When circumferentially cutting the conductor sheath, a cutting tool is used to make multiple circumferential cuts to cut through the conductor sheath.
[0003] Because the sheath of the conductor has a certain degree of rigidity, excessive cutting force applied by the cutting tool to the sheath can easily damage the cutting tool. In related technologies, judging the cutting force of the cutting tool on the sheath relies on the operator's feel and experience, making it difficult to detect the cutting force and easily leading to damage to the cutting tool. Summary of the Invention
[0004] The main objective of this invention is to provide a wire sheath cutting device and a wire sheath cutting method to solve the problem in related technologies that it is inconvenient to detect the cutting force of the cutting head on the sheath, which easily leads to damage to the cutting head.
[0005] To achieve the above objectives, according to one aspect of the present invention, a wire sheath cutting device is provided for cutting the sheath of a wire. The wire sheath cutting device includes: a clamping structure clamping the outside of the wire and capable of rotating relative to the wire in the circumferential direction; a mounting frame disposed on the clamping structure; a mounting shell movably disposed on the mounting frame and engaging with a stop at one end of the mounting frame opposite to the clamping structure, the mounting shell having a mounting cavity; a cutting element retractably disposed within the mounting cavity, the cutting end of the cutting element extending into the clamping structure and abutting against the sheath of the wire; and a first sensing element disposed between the mounting frame and the mounting shell; wherein, when the cutting element abuts against the sheath, the mounting shell engages with and abuts against the stop at the end of the mounting frame opposite to the clamping structure, and the first sensing element senses the abutting force between the mounting shell and the mounting frame to detect the cutting force of the cutting element.
[0006] Furthermore, the mounting frame includes a base, a guide rail disposed on the base, and a stop plate disposed on one end of the guide rail away from the clamping structure.

[0007] Furthermore, the cutting component includes a screw and a cutting part connected to the first end of the screw. The cutting part extends downward through the bottom of the mounting housing.

[0014] Furthermore, the clamping structure includes a first arc-shaped plate, a second arc-shaped plate, and a locking member. The clamping structure is disposed on the first arc-shaped plate. The first arc-shaped plate and the second arc-shaped plate are openable and closable. The first arc-shaped plate and the second arc-shaped plate are fixedly connected by the locking member and form a receiving space for accommodating the wire. The wire is rotatably disposed in the receiving space relative to the clamping structure.
[0015] Furthermore, the clamping structure also includes a first roller, which is rotatably disposed on the first arc plate and extends into the receiving space to abut against the wire, and the wire rotates relative to the clamping structure and drives the first roller to roll; and / or, the clamping structure also includes a second roller, which is rotatably disposed on the second arc plate and extends into the receiving space to abut against the wire, and the wire rotates relative to the clamping structure and drives the second roller to roll.
[0016] Furthermore, the first end of the first arc-shaped plate is hinged to the first end of the second arc-shaped plate. The second end of the first arc-shaped plate is provided with a first flange, and the second end of the second arc-shaped plate is provided with a second flange. A locking member can connect the first flange and the second flange. The locking member includes a stud, a receiving hole, a communicating notch, and a locking head.

The locking head is sleeved on the stud so that the filling section extends into the receiving hole, and the stop section mates with another stop in the first flange and the second flange.
[0017] According to another aspect of the present invention, a method for cutting a conductor sheath is provided, implemented by the aforementioned conductor sheath cutting device. The method includes the following steps: using a clamping structure to clamp the outside of the conductor to fix the conductor; using a cutting element to abut against the conductor, wherein the conductor can apply a reaction force to the cutting element and the mounting housing, so that a first sensing element located on the mounting frame detects the reaction force; controlling the clamping structure to rotate circumferentially along the conductor, and controlling the cutting element to cut the conductor sheath according to the magnitude of the reaction force detected by the first sensing element; and adjusting the cutting depth of the cutting element when the reaction force is not within a preset force range during the cutting process of the cutting element cutting the conductor sheath.
[0018] According to the technical solution of this invention, a conductor sheath cutting device is used to cut the sheath of a conductor. The conductor sheath cutting device includes: a clamping structure, a mounting frame, a mounting shell, a cutting element, and a first sensing element. The clamping structure is clamped around the conductor and can rotate relative to the conductor along its circumference. The mounting frame is mounted on the clamping structure. The mounting shell is movably mounted on the mounting frame and engages with a stop at one end of the mounting frame opposite to the clamping structure; a mounting cavity is provided inside the mounting shell. The cutting element is retractably mounted within the mounting cavity, with its cutting end extending into the clamping structure and abutting against the conductor sheath. Thus, when the clamping structure rotates relative to the conductor, the cutting element can cut the sheath. The cutting element retracts and extends within the mounting cavity to adjust the cutting depth of the cutting element on the sheath. The first sensing element is disposed between the mounting frame and the mounting shell. When the cutting element abuts against the sheath, the mounting shell engages with and abuts against the stop at the end of the mounting frame opposite to the clamping structure; the first sensing element senses the abutting force between the mounting shell and the mounting frame to detect the cutting force of the cutting element. When the cutting element cuts the sheath, it experiences a reaction force from the sheath, which in turn causes the mounting shell outside the cutting element to also experience a force from the sheath. The mounting shell tends to move away from the conductor on the mounting bracket, increasing the contact force between the mounting shell and the mounting bracket. This allows the first sensor to detect the cutting force of the cutting element on the sheath by sensing the contact force between the mounting shell and the mounting bracket. Thus, the first sensor enables timely and quantitative measurement of the cutting force, allowing for timely stopping when the cutting force is excessive, reducing the risk of damage to the cutting head. Therefore, the technical solution of this application effectively solves the problem in related technologies where it is difficult to detect the cutting force of the cutting head on the sheath, easily leading to damage to the cutting head.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.
[0044] like Figures 1 to 7As shown, applying the technical solution of this embodiment, the wire sheath cutting device is used to cut the sheath of the wire 70. The wire sheath cutting device includes: a clamping structure, a mounting frame 20, a mounting shell, a cutting element, and a first sensing element. The clamping structure is clamped on the outside of the wire 70 and can rotate relative to the wire 70 along its circumference. The mounting frame 20 is disposed on the clamping structure. The mounting shell is movably disposed on the mounting frame 20 and cooperates with a stop at one end of the mounting frame 20 opposite to the clamping structure, and a mounting cavity is provided inside the mounting shell. The cutting element is retractably disposed in the mounting cavity, and the cutting end of the cutting element extends into the clamping structure and abuts against the sheath of the wire 70. The first sensing element is disposed between the mounting frame 20 and the mounting shell. Wherein, when the cutting element abuts against the sheath, the mounting shell cooperates with and abuts against the stop at the end of the mounting frame 20 opposite to the clamping structure, and the first sensing element senses the abutment force between the mounting shell and the mounting frame 20 to detect the cutting force of the cutting element.
[0045] Thus, when the clamping structure rotates relative to the conductor 70, the cutting element can cut the sheath. The cutting element extends and retracts within the mounting cavity, allowing the cutting depth of the cutting element on the sheath to be adjustable. A first sensor is positioned between the mounting bracket 20 and the mounting shell. When the cutting element abuts against the sheath, the mounting shell engages with and abuts against the end of the mounting bracket 20 away from the clamping structure. The first sensor senses the contact force between the mounting shell and the mounting bracket 20 to detect the cutting force of the cutting element. When the cutting element cuts the sheath, it experiences a reaction force from the sheath, causing the mounting shell outside the cutting element to also experience a force from the sheath. The mounting shell tends to move away from the conductor 70 on the mounting bracket 20, increasing the contact force between the mounting shell and the mounting bracket 20. This allows the first sensor to detect the cutting force of the cutting element on the sheath by sensing the contact force between the mounting shell and the mounting bracket 20. Thus, the first sensor allows for timely and quantitative measurement of the cutting force, enabling timely stopping when the cutting force is excessive, reducing the risk of damage to the cutting head 422. Therefore, the technical solution of this embodiment effectively solves the problem in the related art that it is inconvenient to detect the cutting force of the cutter head on the sheath, which easily leads to damage to the cutter head.
[0046] It should be noted that the ability of the clamping structure to rotate relative to the conductor 70 in the circumferential direction means that: the conductor 70 is fixed and the clamping structure rotates in the circumferential direction of the conductor 70; or, the clamping structure is fixed and the conductor 70 rotates within the clamping structure along its axis. This facilitates the circumferential cutting of the sheath by the cutting element.
[0047] like Figures 1 to 7As shown, the mounting bracket 20 includes a base 21, a guide rail 22 disposed on the base 21, and a stop plate 23 disposed on the end of the guide rail 22 away from the clamping structure. The mounting shell includes a housing 31 and a guide block 32 connected to the housing 31. A mounting cavity is formed inside the housing 31. The guide block 32 is sleeved on the guide rail 22 and guides the guide rail 22, and the guide block 32 stops the stop plate 23. A first sensing element is disposed between the guide block 32 and the stop plate 23. The arrangement of the guide block 32 and the guide rail 22 facilitates the restriction of the movement direction of the cutting part by the mounting shell, so that the cutting part can move along the guiding direction of the guide rail 22. The arrangement of the stop plate 23 allows the guide block 32 to stop the stop plate 23 when the cutting part abuts against the sheath, thereby limiting the movement distance of the guide block 32 and allowing the first sensing element to better sense the contact force between the mounting bracket 20 and the mounting shell, so as to detect the cutting force of the cutting part on the sheath.
[0048] In this embodiment, the first sensing element is disposed on the surface of the stop plate 23 facing the guide block 32. The housing 31 and the guide block 32 are detachably connected by fasteners to facilitate the assembly of the wire sheath cutting device. There are two guide blocks 32, which are respectively disposed on opposite sides of the housing 31. There are two bases 21, and the guide rails 22 of the two bases 21 are respectively guided and engaged with the two guide blocks 32.
[0049] In this embodiment, when the cutting element performs circumferential cutting on the sheath, if the cutting force detected by the first sensing element changes significantly, it indicates that the cutting of the sheath by the cutting element is unstable, and the cutting element needs to be adjusted in time to protect the cutting element.
[0050] like Figures 1 to 7 As shown, the cutting component includes a screw 41 and a cutting section 42 connected to the first end of the screw 41. The cutting section 42 extends downward through the bottom of the mounting housing, and the top of the mounting housing has a threaded hole 33 that engages with the screw 41. The second end of the screw 41 extends upward through the threaded hole 33 and out of the mounting housing. When the screw 41 moves, the cutting section 42 extends and retracts within the mounting cavity. The screw 41 and the threaded hole 33 facilitate the adjustment of the cutting section 42 within the mounting housing, allowing the length of the cutting section 42 extending out of the mounting housing to be adjustable, thus adjusting the cutting depth of the cutting section 42 on the sheath. When the first sensing element detects excessive cutting force, the length of the cutting section 42 extending out of the mounting housing can be adjusted by turning the screw 41, retracting the cutting section 42 back into the mounting housing to reduce the cutting depth, decrease the cutting force, and reduce the possibility of damage to the cutter head 422.
[0051] like Figures 1 to 7As shown, the cutting section 42 includes a cutter holder 421 connected to the first end of the screw 41 and a cutter head 422 rotatably mounted on the cutter holder 421, with the cutting end being the aforementioned cutter head 422. The cutting component also includes a connecting block 43 disposed at the first end of the screw 41 and an elastic member 44 connecting the connecting block 43 and the cutter holder 421. The connecting block 43 is rotatable relative to the screw 41, allowing the screw 41 to rotate and drive the connecting block 43 to move within the mounting housing, thereby applying a contacting force to the elastic member 44. The elastic member 44 allows the cutter head 422 to float within a certain range relative to the mounting housing. Furthermore, the elastic member 44 acts as a buffer when the cutter head 422 cuts the sheath, further protecting the cutter head 422. Under the elastic force applied by the elastic member 44 to the cutter head 422, the cutter head 422 maintains contact with the sheath, facilitating the circumferential cutting operation of the wire sheath cutting device. The elastic element 44 allows the cutter head 422 to automatically and gradually increase the cutting depth, making operation simple.
[0052] like Figures 7 to 13 As shown, the bottom of the mounting housing has an opening to allow the cutter holder 421 to pass through, allowing the cutter head 422 to extend into the clamping structure. An inwardly flanged edge 34 is provided at the opening of the mounting housing, and a stop protrusion 423 is provided on the cutter holder 421. When the cutting end abuts against the sheath, a preset distance exists between the inwardly flanged edge 34 and the stop protrusion 423, which engages to limit the distance the cutter head 422 extends into the clamping structure. The inwardly flanged edge 34 and the stop protrusion 423 ensure that the cutting piece is fixed within the mounting housing when not in contact with the wire 70, reducing the possibility of the cutting piece detaching from the mounting housing when not in contact with the wire 70. When the cutting end abuts against the sheath, the preset distance between the inwardly flanged edge 34 and the stop protrusion 423 prevents the extension and retraction of the cutting end, facilitating the adjustment of the cutting depth.
[0053] The inventors discovered that in the related technology, when the cutter head cuts the sheath, the skewness of the cutter head can easily cause uneven force on the cutter head, thereby reducing the cutting accuracy and easily damaging the cutter head.
[0054] Therefore, in this embodiment, the clamping structure is further provided with a clearance notch 14 to avoid the cutting end, and a sensing cantilever 60 is provided on the side wall of the clearance notch 14 to abut against the side of the cutting end. The sensing cantilever 60 is set at an angle to the cutting end of the cutting workpiece, and the sensing cantilever 60 is used to detect the amount of deviation of the cutting end of the cutting workpiece. When the cutting end deviates, the sensing cantilever 60 abutting against the side of the cutting end can sense the change in the abutting force, so as to prompt the operator that the cutting end has deviated, so that the cutting of the sheath can be stopped in time when the cutting end deviates, reducing the possibility of damage to the cutter head 422 and improving the cutting accuracy. The sensing cantilever 60 is set at an angle to the cutting end of the cutting workpiece, so that the sensing cantilever 60 can detect the amount of deviation of the cutting end more accurately.
[0055] In this embodiment, there are two sensing arms 60, which are arranged opposite each other on the sidewall of the clearance notch 14. The cutting end of the cutting piece extends between the two sensing arms 60 and abuts against them. Each sensing arm 60 is provided with a second sensor 62. When the values detected by the second sensors 62 on the two sensing arms 60 are equal, it indicates that the cutting end is not skewed. When the values detected by the second sensors 62 on the two sensing arms 60 are not equal, it indicates that the cutting end is skewed. When the values detected by the second sensors 62 on the two sensing arms 60 differ significantly, the cutting piece needs to be adjusted in time to protect it.
[0056] like Figures 7 to 13 As shown, the sensing cantilever 60 includes a suspension rod 61 and a second sensing element 62 disposed on the suspension rod 61. The first end of the suspension rod 61 is fixed to the wall of the clearance notch 14, and the second end of the suspension rod 61 abuts against the side of the cutting end. The suspension rod 61 is positioned to facilitate contact with the side of the cutting end, and the second sensing element 62 is positioned to sense changes in the force acting on the suspension rod 61, thereby detecting the deflection of the cutting end.
[0057] In this embodiment, both the first sensing element and the second sensing element 62 are preferably strain gauges. The strain gauge is subjected to force to produce bending deformation, causing a change in its resistance value. The greater the change in resistance value of the first sensing element, the greater the cutting force of the cutting element on the sheath. The greater the change in resistance value of the second sensing element 62, the greater the deflection of the cutting end of the cutting element. By calibration, the resistance change range of the strain gauge can be correlated with the cutting force or deflection, making it easier to determine whether the cutting force or deflection is within a reasonable range.
[0058] like Figures 7 to 13As shown, the inductive cantilever 60 also includes a rolling element 63, which is disposed at the second end of the suspension rod 61 and abuts against the cutting end of the cutting element. The rolling element 63 reduces friction between the second end of the suspension rod 61 and the cutting element, thereby improving the service life of the cutting element. The suspension rod 61 is a bent rod, with its first end fixed to the wall of the clearance notch 14, and its second end bent towards the guide wire 70. The bent rod design allows the suspension rod 61 to deform along its bending direction when subjected to force, thus guiding the bending direction of the suspension rod 61 under stress.
[0059] In other embodiments, the sensing cantilever 60 further includes a rolling element 63, which is disposed at the second end of the suspension rod 61 and abuts against the cutting end of the cutting element. Alternatively, the suspension rod 61 is a bent rod, with the first end of the bent rod fixed to the wall of the clearance notch 14 and the second end of the bent rod bent toward the wire 70.
[0060] like Figures 7 to 13 As shown, the sensing cantilever 60 also includes a slider 64 and a rod housing 65. The slider 64 is fixedly disposed between the second end of the suspension rod 61 and the rolling element 63, and the rod housing 65 is sleeved on the outside of the suspension rod 61 and has a deformation gap between it and the suspension rod 61. The deformation gap facilitates the deformation of the suspension rod 61 within the rod housing 65. The first end of the rod housing 65 is fixed to the wall of the clearance notch 14, and the second end of the rod housing 65 is provided with a groove 66 that guides and engages with the slider 64. The slider 64 slides within the groove 66 to limit the bending direction of the second end of the suspension rod 61, and the sliding direction of the slider 64 is perpendicular to the axis of the wire 70. The slider 64 and the groove 66 guide the movement of the second end of the suspension rod 61 so that the suspension rod 61 can bend in a preset direction, so that the second sensing element 62 can better receive the deformation of the suspension rod 61, and so that the second sensing element 62 can better detect the deflection of the cutting end.
[0061] In this embodiment, the extension direction of the groove 66 is perpendicular to the guide wire 70, so that the sliding direction of the slider 64 can be perpendicular to the cutting end. The rolling element 63 includes a fixed shell and a rolling ball rotatably disposed in the fixed shell. The fixed shell is fixedly connected to the slider 64, and the rolling ball abuts against the cutting end of the cutting element.
[0062] like Figures 7 to 13As shown, the clamping structure includes a first arc-shaped plate 11, a second arc-shaped plate 12, and a locking member 13. The clamping structure is mounted on the first arc-shaped plate 11, and the first arc-shaped plate 11 and the second arc-shaped plate 12 are closable. The first arc-shaped plate 11 and the second arc-shaped plate 12 are fixedly connected by the locking member 13 and form a receiving space for accommodating the wire 70. The wire 70 is rotatably disposed within the receiving space relative to the clamping structure. The arrangement of the first arc-shaped plate 11 and the second arc-shaped plate 12 facilitates clamping the wire 70 within the receiving space. The locking member 13 facilitates the connection of the first arc-shaped plate 11 and the second arc-shaped plate 12 and facilitates the entry and exit of the wire 70 within the receiving space.
[0063] like Figures 7 to 13 As shown, the clamping structure also includes a first roller 111, which is rotatably mounted on the first arc-shaped plate 11 and extends into the receiving space to abut against the wire 70. The wire 70 rotates relative to the clamping structure, causing the first roller 111 to roll. When the first arc-shaped plate 11 and the second arc-shaped plate 12 clamp the wire 70, the arrangement of the first roller 111 facilitates the rotation of the wire 70 relative to the clamping structure. The clamping structure also includes a second roller 121, which is rotatably mounted on the second arc-shaped plate 12 and extends into the receiving space to abut against the wire 70. The wire 70 rotates relative to the clamping structure, causing the second roller 121 to roll. When the first arc-shaped plate 11 and the second arc-shaped plate 12 clamp the wire 70, the arrangement of the second roller 121 facilitates the rotation of the wire 70 relative to the clamping structure.
[0064] In other embodiments, the clamping structure further includes a first roller 111, which is rotatably mounted on the first arc-shaped plate 11 and extends into the receiving space to abut against the wire 70. The wire 70 rotates relative to the clamping structure, causing the first roller 111 to roll. Alternatively, the clamping structure further includes a second roller 121, which is rotatably mounted on the second arc-shaped plate 12 and extends into the receiving space to abut against the wire 70. The wire 70 rotates relative to the clamping structure, causing the second roller 121 to roll.
[0065] like Figure 13As shown, the first end of the first arc-shaped plate 11 is hinged to the first end of the second arc-shaped plate 12. The second end of the first arc-shaped plate 11 is provided with a first flange 112, and the second end of the second arc-shaped plate 12 is provided with a second flange 122. A locking member 13 can connect the first flange 112 and the second flange 122. The arrangement of the first flange 112 and the second flange 122 facilitates the connection and locking of the locking member 13. The locking member 13 includes a stud 131, a receiving hole 132, a communicating notch 133, and a locking head 134. The stud 131 is rotatably disposed on the second flange 122. The receiving hole 132 and the communicating notch 133 are disposed on the first flange 112, communicating with each other, and the communicating notch 133 penetrates the edge of the first flange 112. The locking head 134 is provided with a threaded inner hole that threadedly engages with the stud 131. The minimum width of the connecting notch 133 is greater than or equal to the diameter of the stud 131, so that the stud 131 can enter the receiving hole 132 through the connecting notch 133. The diameter of the receiving hole 132 is greater than the minimum width of the connecting notch 133, so that the stud 131 can be fixed in the receiving hole 132. The locking head 134 includes a filling section 135 extending into the receiving hole 132 and a stop section 136 cooperating with the stop of the first flange 112. The first flange 112 fits against the second flange 122 so that the stud 131 can enter the receiving hole 132 through the connecting notch 133 after rotation. The locking head 134 is sleeved on the stud 131 so that the filling section 135 extends into the receiving hole 132, and the stop section 136 cooperates with the stop of the first flange 112. The filling section 135 reduces the wobble of the stud 131 in the receiving hole 132, making the connection between the first flange 112 and the second flange 122 more reliable.
[0066] In other embodiments, the stud 131 is rotatably disposed on the first flange 112, and the receiving hole 132 and the communicating notch 133 are disposed on the second flange 122, the receiving hole 132 and the communicating notch 133 being connected, the communicating notch 133 penetrating the edge of the second flange 122. The locking head 134 is provided with a threaded inner hole that is threadedly engaged with the stud 131; the minimum width of the communicating notch 133 is greater than or equal to the diameter of the stud 131, the diameter of the receiving hole 132 is greater than the minimum width of the communicating notch 133, and the locking head 134 includes a filling section 135 extending into the receiving hole 132 and a stop section 136 that engages with the stop of the second flange 122. The first flange 112 and the second flange 122 fit together so that the stud 131 can enter the receiving hole 132 through the connecting notch 133 after rotation. The locking head 134 is sleeved on the stud 131 so that the filling section 135 extends into the receiving hole 132. The stop section 136 is stopped and engaged with the second flange 122.
[0067] According to another aspect of the invention, such as Figure 14As shown, a method for cutting wire sheaths is provided, implemented using the aforementioned wire sheath cutting device. The method includes the following steps: using a clamping structure to clamp the outside of the wire 70 to fix the wire 70; using a cutting element to abut against the wire 70, whereby the wire 70 can apply a reaction force to the cutting element and the mounting housing, so that a first sensing element located on the mounting bracket 20 detects the reaction force; controlling the clamping structure to rotate circumferentially along the wire 70, and controlling the cutting element to cut the sheath of the wire 70 according to the magnitude of the reaction force detected by the first sensing element; adjusting the cutting depth of the cutting element when the reaction force is not within a preset force range during the cutting process; since the aforementioned wire sheath cutting device can solve the problem in related technologies where it is inconvenient to detect the cutting force of the cutting head on the sheath, which easily leads to damage to the cutting head, the wire sheath cutting method implemented by the aforementioned wire sheath cutting device can also solve the same technical problem.
[0068] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.
[0069] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.
[0070] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.
