Description

[Technical Field]

[0001] This utility model relates to a connector assembly, and more particularly to a connector assembly for connecting a chip to a circuit board. [Background Technology]

[0002] A connector assembly includes an insulating body, conductive terminals housed in the insulating body, and a cover covering the insulating body. The insulating body has a receiving cavity for housing a chip, and the cover has an opening corresponding to the receiving cavity. A fixing base is provided with multiple positioning posts, and a clamping member carrying a chip is vertically mounted on the insulating body, wherein the clamping member passes through the positioning posts for positioning.

[0003] However, when it comes to chip removal, the usual method is to manually pick up the clamp and chip together from the insulating body. But as the size of chips increases and the design trend of connectors is towards a lower and lower profile, it is no longer easy to remove large chips from the insulating body by manual picking alone.

[0004] Therefore, it is necessary to design a new connector combination to overcome the above-mentioned defects. [Utility Model Content]

[0005] The purpose of this invention is to provide a connector assembly in which an elastic element is disposed below a clamping element. After the external force is removed, the elastic element automatically springs the clamping element upward, making it easy to remove the clamping element carrying the chip.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A connector assembly, mounted on a circuit board, includes: a connector comprising multiple terminals, each terminal including a resilient contact portion for contacting a chip, such that the resilient contact portion has a compression stroke in the vertical direction; a mounting base mounted on the circuit board, the mounting base having a base plate surrounding the connector; multiple positioning posts surrounding the multiple connectors, the positioning posts protruding upward relative to the base plate; a clamping member for carrying the chip and mounting it vertically on the connector, the clamping member having a positioning hole corresponding to each positioning post, the size of the positioning hole being larger than the size of the portion of the positioning post above the base plate, such that the positioning post passes through the corresponding positioning hole vertically; multiple elastic members corresponding to the multiple positioning posts, the elastic members being disposed below the clamping member for directly or indirectly supporting the clamping member, when an external force is applied above the clamping member, the elastic members are subjected to force and elastically deform; when the external force applied above the clamping member disappears, the elastic members return to their original state and spring the clamping member upward, the positioning posts are always received in the corresponding positioning holes, and the operator can remove the clamping member carrying the chip from above the connector.

[0008] Furthermore, when the chip is fully positioned in the connector, when the elastic element is deformed by the external force applied above the clamping member, the amount of deformation of the elastic element in the vertical direction is greater than the compression stroke of the elastic contact.

[0009] Furthermore, the connector assembly further includes multiple gaskets corresponding to multiple positioning posts. The elastic element is a spring. Each positioning post includes a riveting part, a rod part, and a limiting part. The rod part connects the riveting part and the limiting part. The riveting part is riveted to the base plate, and the rod part is located above the base plate. In the direction perpendicular to the vertical direction, the limiting part expands outward relative to the rod part. Both the gasket and the elastic element are sleeved on the rod part. In the vertical direction, the gasket is located between the limiting part and the corresponding elastic element. The gasket is restricted by the limiting part to prevent it from detaching upward from the positioning post.

[0010] Furthermore, the positioning hole consists of a guide hole and a receiving hole. The guide hole is connected downward to the receiving hole, and the receiving hole expands outward relative to the guide hole in a direction perpendicular to the vertical direction. The elastic element is received in the receiving hole.

[0011] Furthermore, in the vertical direction, the height of the receiving hole is greater than the height of the guide hole.

[0012] Furthermore, the connector assembly further includes multiple gaskets corresponding to multiple positioning posts, the elastic element is a spring, the top of the receiving hole forms a stop surface around the guide hole, and in the vertical direction, the gaskets are sleeved on the positioning posts and located between the stop surface and the elastic element, wherein the gaskets abut against the stop surface and the elastic element.

[0013] Furthermore, the clamping member has a main body and at least one boss extending downward from the lower surface of the main body and corresponding to a plurality of positioning holes. The positioning holes penetrate the main body and the boss vertically. The positioning holes include a receiving hole formed in the boss, and the elastic member is received in the receiving hole.

[0014] Furthermore, in the vertical direction, the thickness of the boss is greater than the thickness of the main body.

[0015] Furthermore, the clamping member includes a through hole extending vertically to expose a portion of the chip, and the connector assembly further includes a pressure cap that covers the clamping member. The pressure cap has an opening corresponding to the through hole and a plurality of clearance holes corresponding to the plurality of positioning posts. The positioning posts pass through the corresponding clearance holes, and the pressure cap provides external force to press against the clamping member.

[0016] Furthermore, in the front-rear direction, the rear end of the gland is pivotally connected to the fixed seat, causing the gland to rotate around the fixed seat, so that the width of the positioning hole in the front-rear direction is greater than the width in the left-right direction.

[0017] Furthermore, a heat sink is installed on top of the connector assembly. The heat sink is used for heat dissipation of the chip. The heat sink includes a substrate. Multiple clearance grooves are formed by recessing from the bottom surface of the substrate to correspond to multiple positioning posts. The positioning posts pass upward through the corresponding clearance holes and the corresponding positioning holes and extend into the corresponding clearance grooves.

[0018] Furthermore, the connector assembly further includes multiple locking mechanisms for securing the gland to the mounting base, wherein the multiple locking mechanisms correspond one-to-one with multiple elastic elements and are arranged adjacent to each other.

[0019] Furthermore, a heat sink is installed on top of the connector assembly. The heat sink is used for heat dissipation of the chip. The heat sink includes a substrate and multiple clearance grooves formed by recessing upward from the bottom surface of the substrate, corresponding to multiple positioning posts. When the heat sink is pressed against the chip, each positioning post extends upward and is received in the corresponding clearance groove.

[0020] Furthermore, the chip includes a base and a protrusion extending upward from the base, and the heat sink includes at least one protrusion extending downward from the lower surface of the substrate. When the protrusion is pressed against the protrusion, the width of the protrusion is greater than the width of the protrusion in the left-right direction and the front-back direction.

[0021] Compared with the prior art, the connector assembly of this utility model has the following beneficial effects:

[0022] Multiple elastic elements are fitted onto multiple positioning posts. The elastic elements are located below the clamping member to directly or indirectly support it. When the chip is fully positioned in the connector, the elastic elements are subjected to force and deform elastically. The amount of deformation in the vertical direction is greater than the compression stroke of the elastic contact. When the external force applied above the clamping member disappears, the elastic elements recover and spring the clamping member upward. The positioning posts are always received in the corresponding positioning holes. The operator can remove the clamping member carrying the chip from above the connector together, which improves the convenience of chip removal and ensures that the terminals are not easily damaged in case of accidents during chip removal.

Detailed Implementation Methods

[0038] To facilitate a better understanding of the purpose, structure, features, and effects of this utility model, the present utility model will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0039] For ease of understanding, we define the Z-axis extension direction as the up-down direction (where the positive Z-axis direction is the up direction), the Y-axis extension direction as the left-right direction (where the positive Y-axis direction is the right direction), and the X-axis direction as the front-back direction (where the positive X-axis direction is the front direction).

[0040] like Figures 1 to 13 The diagram shown is a related illustration of the connector assembly 100 of this utility model. Figure 1 As shown, connector assembly 100 is mounted to a circuit board 200 for connection to a chip 300, and a heat sink 400 is locked above connector assembly 100 for heat dissipation of chip 300.

[0041] like Figure 2 As shown, the connector assembly 100 includes a connector 1 mounted on the upper surface of the circuit board 200. The connector 1 is electrically connected to the circuit board 200. The connector 1 includes an insulating body 11 and a plurality of terminals 12 housed in the insulating body 11. The insulating body 11 has a housing cavity 111 for housing the chip 300. The housing cavity 111 extends upward through the insulating body 11. The plurality of terminals 12 are located in the portion of the insulating body 11 located below the housing cavity 111. Each terminal 12 includes an elastic contact portion 121. A portion of the elastic contact portion 121 protrudes upward into the housing cavity 111. In the vertical direction, when the elastic contact portion 121 contacts the chip 300 and is subjected to downward pressure from the chip 300, the elastic contact portion 121 has a compression stroke H.

[0042] like Figure 2 As shown, the connector assembly 100 includes a fixed base 2 surrounding the connector 1, a plurality of positioning posts 3, a plurality of elastic elements 4, a plurality of gaskets 5, a pressure cover 6 covering the connector 1 and pivotally connected to one end of the fixed base 2, a clamping member 7 carrying a chip 300 mounted on the connector 1, a plurality of locking mechanisms 8, and a plurality of locking members 9.

[0043] like Figure 2 As shown, the mounting base 2 is mounted on the circuit board 200. The mounting base 2 has a flat base plate 21 and a window 22 that runs vertically through the base plate 21. The base plate 21 is made of metal and is located on the upper surface of the circuit board 200. The connector 1 is installed in the window 22. The mounting base 2 is also provided with a first pivot part 23. In this embodiment, the first pivot part 23 is located behind the window 22 and above the base plate 21. In other embodiments, the first pivot part 23 can also be located at other positions of the mounting base 2 as needed.

[0044] like Figure 2 As shown, multiple positioning posts 3 are arranged around the window 22 and protrude upward relative to the base plate 21. Specifically, there are four positioning posts 3, which are located around the window 22 and are roughly distributed near the four corners of the base plate 21.

[0045] like Figure 5As shown, the positioning post 3 is made of metal. Each positioning post 3 includes a riveting part 31, a rod part 32, and a limiting part 33. The rod part 32 connects the riveting part 31 and the limiting part 33. The riveting part 31 is connected to the bottom end of the rod part 32, and the limiting part 33 is connected to the top end of the rod part 32. The riveting part 31 is riveted to the base plate 21, and the rod part 32 is located above the base plate 21. In the direction perpendicular to the up and down direction, the limiting part 33 expands outward relative to the rod part 32. In this embodiment, the riveting part 31, the rod part 32, and the limiting part 33 are all cylindrical structures and are coaxially arranged. The diameter of the riveting part 31 is smaller than the diameter of the rod part 32, and the diameter of the rod part 32 is smaller than the diameter of the limiting part 33.

[0046] like Figure 5 As shown, each positioning post 3 is equipped with an elastic element 4 and a washer 5. In this embodiment, the elastic element 4 is a spring, and the washer 5 is made of stamped metal sheet and has a ring structure. In other embodiments, the elastic element 4 can also be other elastically deformable elements. The elastic element 4 and the washer 5 are both sleeved on the rod portion 32 of the corresponding positioning post 3. The washer 5 is located above the corresponding elastic element 4, and the elastic element 4 abuts downward against the base plate 21. The outer diameter of the washer 5 is larger than the outer diameter of the elastic element 4, and the inner diameter of the washer 5 is smaller than the diameter of the limiting portion 33, so as to prevent the washer 5 and the corresponding elastic element 4 from disengaging upward from the corresponding positioning post 3.

[0047] like Figure 2 and Figure 8 As shown, the pressure cap 6 is made of metal and includes a flat plate portion 61 and a second pivot portion 62. The flat plate portion 61 has a through opening 611 extending vertically. The flat plate portion 61 has multiple clearance holes 612 and multiple avoidance holes 613. Each avoidance hole 77 corresponds to each locking member 9. In this embodiment, the number of clearance holes 612 is the same as the number of positioning pins 3, which is four. The width of the clearance holes 612 in the front-back direction is greater than the width in the left-right direction. The width of the avoidance holes 613 in the front-back direction is also greater than the width in the left-right direction so that when the pressure cap 6 is closed on the connector 1, the positioning pins 3 do not interfere with the pressure cap 6, and the structural strength of the pressure cap 6 is guaranteed. Of course, in other embodiments, other shapes are also possible. The second pivot portion 62 is connected to the rear end of the flat plate portion 61. The second pivot portion 62 is pivotally connected to the first pivot portion 23, so that the cover 6 can rotate relative to the fixed seat 2 and cover the connector 1. In this embodiment, the second pivot portion 62 is located at the rear end of the cover 6. In other embodiments, the second pivot portion 62 can also be provided at other ends of the cover 6 as needed.

[0048] like Figure 2 and Figure 6As shown, the clamping member 7 is made of plastic material and includes a main body 71, a through hole 72, multiple snap-fit ​​parts 73, multiple positioning parts 74, multiple bosses 75, multiple positioning holes 76, and multiple clearance holes 77. The through hole 72 extends vertically through the main body 71 and is generally rectangular. The snap-fit ​​parts 73 extend downward from the main body 71 and surround the through hole 72. The snap-fit ​​parts 73 are located on the left and right sides of the through hole 72. In other embodiments, snap-fit ​​parts 73 may be provided on the left and right sides and the front and rear sides, or on the front and rear sides. The positioning parts 74 extend downward from the main body 71 and surround the through hole 72. In this embodiment, there are four positioning parts 74, which are generally located at the four corners of the through hole 72, corresponding to the adjacent outer positions. The positioning parts 74 are generally L-shaped. A boss 75 extends downward from the main body 71, and multiple bosses 75 surround the through hole 72. In the vertical direction, the thickness of the boss 75 is greater than the thickness of the main body 71. Each positioning hole 76 penetrates the main body 71 and one of the bosses 75 vertically. In this embodiment, four bosses 75 are provided, approximately located at the four corners of the through hole 72, corresponding to the adjacent outer positions. The boss 75 corresponding to the same corner is located further away from the through hole 72 relative to the positioning part 74, and the boss 75 is connected to the corresponding positioning part 74. A clearance hole 77 penetrates the main body 71 vertically, and multiple clearance holes 77 are located on the left and right sides of the through hole 72. Multiple clearance holes 77 can also be located on the front and rear sides of the through hole 72.

[0049] like Figure 4 As shown, the positioning hole 76 consists of a guide hole 761 and a receiving hole 762. Specifically, the guide hole 761 is formed in the main body 71, and the receiving hole 762 is formed in the boss 75. The guide hole 761 communicates downward with the receiving hole 762. The receiving hole 762 expands outward relative to the guide hole 761 in a direction perpendicular to the vertical direction. In the vertical direction, the height of the receiving hole 762 is greater than the height of the guide hole 761. For the same positioning hole 76, the top of the receiving hole 762 forms a stop surface 763 around the corresponding guide hole 761.

[0050] like Figure 8 and Figure 9 As shown, multiple locking mechanisms 8 fix the pressure cap 6 and the fixing base 2 together. The multiple locking mechanisms 8 correspond one-to-one with multiple elastic elements 4 and are arranged adjacent to each other. In this embodiment, the locking mechanism 8 consists of a bolt 81 and a nut 82. The bolt 81 is positioned on the pressure cap 6 and the nut 82 is fixed on the base plate 21 of the fixing base 2. In other embodiments, the nut 82 can also be positioned on the pressure cap 6 and the bolt 81 can be fixed on the base plate 21 of the fixing base 2.

[0051] like Figure 2As shown, the chip 300 includes a base 301 and a protrusion 302 formed upward from the base 301. In this embodiment, the protrusion 302 is in a stepped shape.

[0052] like Figure 2 and Figure 10 , Figure 4 As shown, the heat sink 400 includes a base plate 401, a protrusion 402, a plurality of clearance grooves 403, and a plurality of locking holes 404. The protrusion 402 extends downward from the lower surface of the base plate 401, the clearance grooves 403 are recessed upward from the lower surface of the base plate 401, and the locking holes 404 penetrate the base plate 401 vertically. A portion of the positioning post 3 protrudes into the clearance groove 403, and the locking member 91 passes through the locking hole 404. Figure 5 As shown, the gasket 5 and the elastic element 4 are first fitted onto the rod 32 from the riveting part 31, and then the riveting part 31 of the positioning post 3 is riveted and fixed to the base plate 21. In this way, the gasket 5 and the elastic element 4 are limited between the limiting part 33 and the base plate 21. The nut 82 in the locking mechanism 8 and the locking element 91 in the locking member 9 are fixed to the base plate 21 of the fixing seat 2, and the second pivot part 62 of the pressure cover 6 is pivotally connected to the first pivot part 23 of the fixing seat 2.

[0053] like Figure 1 and Figure 3 As shown, multiple locking components 9 fix the heat sink 400 together with the fixing base 2, locking the heat sink 400 above the connector 1. The locking component 9 includes a locking member 91 and a locking member 92 with threaded engagement. The locking member 91 is fixed to the base plate 21 of the fixing base 2, and a portion of the multiple locking members 91 passes through multiple clearance holes 77 one by one. In this embodiment, the locking member 91 is a screw and the locking member 92 is a nut. Of course, in other embodiments, the locking member 91 can also be a nut and the locking member 92 can be a screw.

[0054] like Figure 7 As shown, the chip 300 is mounted on the clamping member 7. The base 301 is located below the main body 71. Multiple latching parts 73 are fastened to the bottom of the base 301. A portion of the protrusion 302 extends upward through the through hole 72 above the clamping member 7. A portion of the main body 71 is located around the through hole 72 and is directly above the base 301. Thus, the base 301 can be positioned vertically by the main body 71 and the latching parts 73, thereby positioning the chip 300 on the clamping member 7.

[0055] like Figure 8 and Figure 12As shown in Figure a, when the clamping member 7 carrying the chip 300 is vertically mounted on the connector 1 in the vertical direction and the cover 6 is not rotated to close, a portion of the multiple locking members 91 passes upward through the multiple clearance holes 77 in a corresponding manner. In the direction perpendicular to the vertical direction, since the size of the positioning hole 76 is larger than the size of the portion of the positioning post 3 above the base plate 21, that is, the size of the positioning hole 76 is larger than the size of the limiting part 33 and the size of the rod part 32, the positioning post 3 passes upward through the positioning hole 76. Specifically, the positioning post 3 passes through the receiving hole 762 and the guide hole 761 sequentially from bottom to top. Since the receiving hole 762 expands outward relative to the guide hole 761 in the direction perpendicular to the vertical direction, and the outer diameter of the gasket 5 is smaller than the diameter of the receiving hole 762, the gasket 5 and part of the elastic member 4 are both received in the receiving hole 762. The gasket 5 abuts against the stop surface 763 and the elastic member 4 from the top and bottom. In this way, the elastic member 4 indirectly supports the clamping member 7 through the gasket 5. In the embodiment without the gasket 5, the elastic member 4 can also abut against the bottom plate 21 and the stop surface 763 from the top and bottom, and directly support the clamping member 7. At this time, the elastic contact portion 121 of the chip 300 and the terminal 12 does not make contact.

[0056] like Figure 4 and Figure 9 , Figure 12As shown in b, after the pressure cap 6 rotates to cover the connector 1, the protrusion 302 of the chip 300 passes upward through the opening 611, the protrusion 402 is exposed above the pressure cap 6, the positioning post 3 passes upward through the corresponding clearance hole 612, the locking member 91 passes upward through the corresponding clearance hole 613, the pressure cap 6 provides a downward external force to press against the main body 71 of the clamping member 7 and the step of the stepped protrusion 302 of the chip 300, and the pressure cap 6 is fixed together with the fixing seat 2 by multiple locking mechanisms 8. Specifically, the bolt 81 positioned on the pressure cap 6 is locked to the nut 82 fixed on the fixing seat 2. During the locking process of the pressure cap 6 and the fixing seat 2, the chip 300 and the clamping member 7 move downward together, and the stop surface 763 pushes the pad 5 downward, so that the pad The sheet 5 further compresses the elastic element 4 downwards. Since the height of the receiving hole 762 is greater than the height of the guide hole 761, another part of the elastic element 4 is further received in the receiving hole 762, which reduces the overall height of the connector assembly 100. The positioning part 74 moves downwards and is received between the connector 1 and the fixing seat 2, so that the clamping part 7 is accurately positioned on the connector 1, that is, the chip 300 is completely positioned on the connector 1, so that the chip 300 is accurately connected to the multiple terminals 12. Because an external force is applied above the clamping part 4 (that is, the downward pressure applied to the clamping part 7 after the pressure cover 6 is closed on the connector 1), the elastic element 4 is subjected to force and elastically deformed. In the vertical direction, the deformation amount D of the elastic element 4 is greater than the compression stroke H of the elastic contact part 121. The multiple locking mechanisms 8 correspond one-to-one with the multiple elastic elements 4 and are arranged adjacently, which can enhance the pressing force of the pressure cover 6 on the elastic element 4, and at the same time make the pressure on each elastic element 4 uniform and dispersed, preventing any elastic element 4 from being subjected to excessive pressure and causing plastic deformation.

[0057] like Figure 4 and Figure 10 As shown, after the pressure cap 6 is fitted onto the connector 1 and the heat sink 400 is installed, the protrusion 402 facing the chip 300 abuts against the protrusion 302 of the chip 300. At this time, the width of the protrusion 402 is greater than the width of the protrusion 302 in the left-right and front-back directions, so as to increase the pressing force of the heat sink 400 on the protrusion 302 and also make the pressing force on the protrusion 302 evenly distributed. In this embodiment, the width of the protrusion 402 is greater than the width of the base 301 in the left-right and front-back directions. The positioning post 3, which has passed through the positioning hole 76 and the clearance hole 612, extends upward and is received in the clearance groove 403, so that the positioning of the clamping member 7, the pressure cap 6 and the heat sink 400 can be achieved by the positioning post 3 without the need for multiple positioning structures. At the same time, the locking member 91 passes through the locking hole 404 and cooperates with the locking member 92 to fix the heat sink 400 to the fixing base 2. At this time, the connector assembly 100 and the heat sink 400 are assembled.

[0058] like Figure 12 b and Figure 13 As shown, after the heat sink 400 is removed from the mounting base 2, the locking mechanism 8 is unlocked and the pressure cover 6 is opened. At this time, the external force on the main body 71 of the clamping member 7 and the protrusion 302 of the chip 300 disappears. During the recovery process of the elastic member 4, the clamping member 7 is lifted upward. The chip 300 moves upward with the clamping member 7 and disconnects from the terminal 12. Then, the operator can remove the clamping member 7 carrying the chip 300 from above the connector 1.

[0059] During the above process, the positioning post 3 always passes through the positioning hole 76 to prevent the clamping member 7 from being directly ejected from the positioning post 3 under the action of the elastic member 4, which would cause the chip 300 to be ejected as well, resulting in damage to the chip 300.

[0060] In summary, the connector assembly 100 of this utility model has the following beneficial effects:

[0061] (1) Compared with the prior art, this utility model uses multiple elastic elements 4 correspondingly sleeved on multiple positioning posts 3. The elastic elements 4 are set below the clamping member 7 to directly or indirectly support the clamping member 7. The elastic elements 4 are elastically deformed under force, and the amount of deformation D in the vertical direction is greater than the compression stroke H of the elastic contact part 121. When the external force applied above the clamping member 7 disappears, the elastic elements 4 recover and the clamping member 7 is lifted upward. The positioning post 3 is always received in the corresponding positioning hole 76. The operator can take out the clamping member 7 carrying the chip 300 from above the connector 1 together, which improves the convenience of taking out the chip 300 and ensures that the terminal 12 is not easily damaged if an accident occurs during the process of taking out the chip 300.

[0062] (2) The positioning hole 76 is composed of a guide hole 761 and a receiving hole 762. When the positioning post 3 passes through the positioning hole 76 upward, the elastic element 4 is partially received in the receiving hole 762 in the positioning hole 76. The height of the receiving hole 762 is set to be greater than the height of the guide hole 761, which reduces the height generated by the elastic element 4 lifting the clamping element 7, so that the overall height of the connector assembly 100 is reduced after assembly, which meets the current trend of connector 1 becoming lower in height.

[0063] (3) Multiple locking mechanisms 8 fix the cover 6 and the fixed seat 2 together. Multiple locking mechanisms 8 correspond one-to-one with multiple elastic elements 4 and are arranged adjacent to each other. This can enhance the pressing force of the cover 6 on the elastic element 4, while making the pressure on the elastic element 4 uniform and dispersed, preventing the elastic element 4 from being subjected to excessive pressure and causing plastic deformation.

[0064] (4) The width of the clearance hole 612 in the front-to-back direction is greater than the width in the left-to-right direction, so that when the cover 6 is closed on the connector 1, the positioning post 3 interferes with the cover 6, and the structural strength of the cover 6 is guaranteed.

[0065] (5) The protrusion 402 facing the chip 300 abuts against the protrusion 302 of the chip 300. In the left-right direction and the front-back direction, the width of the protrusion 402 is greater than the width of the protrusion 302, so as to increase the pressure of the heat sink 400 on the protrusion 302, and at the same time, the pressure on the protrusion 302 is evenly distributed.

[0066] (6) When the cover 6 is closed on the connector 1 and the heat sink 400 is installed, the positioning pin 3 passes through the positioning hole 76 and the clearance hole 612 and extends upward into the clearance groove 403. Without using multiple positioning structures, the positioning pin 3 can be used to position the clamping part 7, the cover 6 and the heat sink 400.

[0067] The above detailed description is only a description of the preferred embodiment of this utility model and is not intended to limit the patent scope of this invention. Therefore, all equivalent technical changes made using the content of this invention's specification and illustrations are included within the patent scope of this invention.
