Furthermore, the present invention may repeat reference numerals and/or letters in the various examples, such repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. In addition, the present invention provides examples of various specific processes and materials, but one of ordinary skill in the art may recognize applications of other processes and/or uses of other materials.

Referring to fig. 1 and 2, an input device 100 according to an embodiment of the present invention includes a touch panel 10, a bezel 20, and a fingerprint chip package structure 30.

The input module 100 of the embodiment of the invention can be applied to the terminal 1000, and the terminal 1000 is an electronic device such as a mobile phone or a tablet computer. It is understood that terminal 1000 includes but is not limited to the examples of the present embodiments.

Specifically, the touch panel 10 includes an upper surface 12 and a lower surface 14. The upper surface 12 is opposite the lower surface 14. It is understood that the upper surface 12 of the touch panel 10 is an appearance surface of the input assembly 100, facing the user. A user can perform a gesture operation on upper surface 12, such as clicking or sliding, to control terminal 1000 to implement a corresponding function.

The material of the touch panel 10 may be made of a light-transmitting material such as glass, ceramic, or sapphire. Since the touch panel 10 is an input part of the terminal 1000, the touch panel 10 is often contacted by a collision or scratch or the like. For example, when the user puts the terminal 1000 in a pocket, the touch panel 10 may be scratched by a key in the pocket of the user and damaged.

Therefore, a material having a relatively high hardness, such as the sapphire material described above, may be used as the material of the touch panel 10. Of course, a protective cover plate may be attached to the upper surface 12 of the touch panel 10 to prevent the touch panel 10 from being scratched.

Further, the touch panel 10 includes a display area 15 and a non-display area 16. Generally, the middle area of the touch panel 10 serves as a display area 15, and a non-display area 16 is disposed around the display area 15. For example, the non-display area 16 is disposed on the top side or the bottom side of the display area 15.

Since the touch panel 10 is made of a light-transmitting material, a user can view contents displayed on the screen of the terminal 1000 through the display area 15.

To make terminal 1000 more aesthetically pleasing, ink can be sprayed on lower surface 14 of non-display area 16, wherein the ink can be white, black or blue, for example, and the specific case can be set according to actual requirements. The ink can not only meet the requirements of users on the terminal 1000 with different colors, but also cover the structure inside the terminal 1000 to achieve the effect of beautifying the terminal 1000.

It is understood that the shape of touch panel 10 can be specifically designed according to the shape of terminal 1000, such as a rounded rectangle.

Further, the touch panel 10 is opened with a mounting hole 17. In the present embodiment, the mounting hole 17 is a through hole penetrating the upper surface 12 and the lower surface 14. In other embodiments, the mounting hole 17 may be a blind hole formed in the lower surface 14.

In the present embodiment, the mounting hole 17 has an oblong shape. Of course, in other embodiments, the mounting hole 17 may be designed to have a different shape, such as a circular or oval shape, according to specific requirements. Therefore, the example of the shape of the mounting hole 17 of the present embodiment is not to be construed as limiting the present invention.

In some embodiments, the bezel 20 is disposed through the mounting hole 17 and is fixedly connected to the touch panel 10. The fingerprint chip package structure 30 is accommodated in the decoration ring 20 and is fixedly connected with the decoration ring 20.

Generally, the receiver of terminal 1000 is arranged in the top area of terminal 1000. Therefore, in order to prevent the mounting hole 17 from interfering with the receiver, it is preferable that the mounting hole 17 is opened at a bottom area of the touch panel 10, thereby providing a large design space for the mounting hole 17. Further, the mounting hole 17 is opened in the non-display area 16 of the touch panel 10.

Preferably, the mounting hole 17 is opened at a middle position of the bottom area of the touch panel 10, so that the touch panel 10 has a substantially symmetrical structure. Therefore, the terminal 1000 is more attractive and convenient for the user to operate.

When the mounting hole 17 is a through hole, in manufacturing the input assembly 100, the bezel 20 may be first installed into the mounting hole 17 from below the touch panel 10, and then glue may be applied to a gap between an inner wall of the mounting hole 17 and the bezel 20, so as to fixedly connect the bezel 20 to the touch panel 10.

Then, the fingerprint chip package structure 30 is installed into the decoration ring 20 from the top of the touch panel 10, and the fingerprint chip package structure 30 and the decoration ring 20 are fixedly connected by using glue.

When the mounting hole 17 is a blind hole, the fingerprint chip package structure 30 may be first installed in the decoration ring 20, and then the decoration ring 20 with the fingerprint chip package structure 30 may be installed in the mounting hole 17, and the decoration ring 20 and the touch panel 10 may be fixed by using glue.

Referring to fig. 3-5, in some embodiments, the decorative ring 20 includes a decorative ring 21 and a supporting rim 22. The support rim 22 extends inwardly from the inner wall 211 of the decorative ring 21.

The support edge 22 of the decoration ring 20 of the embodiment of the invention can support and position the fingerprint chip packaging structure 30, thereby improving the assembly efficiency of the fingerprint chip packaging structure 30 and the decoration ring 20.

That is, the fingerprint chip package 30 is supported on the support rim 22. When the fingerprint chip package structure 30 is installed in the decoration ring 21, the fingerprint chip package structure 30 can be pressed from top to bottom, and if the position of the fingerprint chip package structure 30 can not be moved any more, it indicates that the fingerprint chip package structure 30 is abutted against the support edge 22 and is installed at a predetermined position.

It will be appreciated that the trim ring 21 is formed with a receiving aperture 212 and the support rim 22 is located within the receiving aperture 212. The receiving hole 212 may have a straight column shape, or the inner wall 211 may have a straight line shape, so that the fingerprint chip package 30 can be quickly installed in the receiving hole 212.

The receiving hole 212 and the supporting edge 22 may be formed by removing material from the component by cutting, or may be formed by casting or the like.

In order to ensure the strength of the bezel 20, the bezel 20 is preferably made of metal, such as stainless steel, so as to meet the strength requirement of the bezel 20, and also has corrosion resistance, thereby prolonging the service life of the bezel 20. Of course, the bezel 20 may be made of other materials such as plastic.

In some embodiments, further, the fingerprint chip package 30 is received in the decoration ring 21 and supported on the supporting rim 22.

In some embodiments, the support rim 22 is perpendicular to the inner wall 211 of the trim ring 21.

Thus, the support edge 22 is easily formed, and the manufacturing cost of the trim ring 21 can be reduced. In addition, when the input assembly 100 is manufactured, the supporting rim 22 is located in a horizontal position, and the inner wall 211 of the decoration ring 21 is located in a vertical position, so that the surface of the fingerprint chip package 30 engaged with the supporting rim 22 is a horizontal surface, which can simplify the structure of the fingerprint chip package 30 supported on the supporting rim 22.

In some embodiments, the trim ring 21 includes a first bottom surface 213 coupled to the inner wall 211, and the lower surface 221 of the support rim 22 is flush with the first bottom surface 213.

In the decoration ring 21 with the same height, as above, a larger accommodating space may be formed in the decoration ring 21 to ensure that the fingerprint chip package structure 30 may be accommodated in the decoration ring 21.

Or, under the condition that the thickness of the fingerprint chip package structure 30 is not changed, the height of the decoration ring 21 is smaller, so that the thickness of the input assembly 100 can be reduced, and a design basis can be provided for the thickness reduction of the terminal 1000.

In some embodiments, the trim ring 21 includes a top wall 214. The top wall 214 is connected to the inner wall 211. The top wall 214 includes a guide ramp 2142 facing into the bezel 20.

Thus, the guiding inclined plane 2142 can guide the finger of the user to smoothly enter the decoration ring 21 for fingerprint identification operation, and the accuracy of the fingerprint identification operation performed by the user can be improved. Further, a shiny metal layer (e.g., chrome layer) may be plated on the guide slope 2142 to make the decoration ring 21 more beautiful.

It is understood that the guiding inclined surface 2142 is a ring-shaped surface, which facilitates a user to insert a finger into the decoration ring 21 from various directions to press the fingerprint chip package 30 for fingerprint recognition operation.

In some embodiments, support rim 22 is formed with relief holes 222.

In this way, the avoiding hole 222 facilitates the trace layout of the first flexible circuit board 40 connected to the fingerprint chip package structure 30. For example, the first flexible circuit board 40 may pass through the avoiding hole 222 to be connected with the fingerprint chip package structure 30 (as shown in fig. 2).

In some embodiments, the avoiding hole 222 has a rounded rectangular shape, and the sidewall 2221 of the avoiding hole 222 is formed with an avoiding groove 2222 along the axial direction of the avoiding hole 222, and the avoiding groove 2222 communicates with the avoiding hole 222.

For example, as shown in fig. 2, after the first flexible circuit board 40 is connected to the fingerprint chip package structure 30, it first extends in the direction of the avoiding groove 2222, and then bends to make a detour. Therefore, the avoiding groove 2222 can prevent the first flexible circuit board 40 from interfering with the side wall 2221, which is beneficial to the wiring of the first flexible circuit board 40.

It can be understood that the first flexible circuit board 40 is electrically connected to the fingerprint chip package structure 30.

In some embodiments, the fingerprint chip package 30 is fixedly disposed on the first flexible circuit board 40. For example, the fingerprint chip package 30 is fixed on the first flexible circuit board 40 by adhesive bonding.

In some embodiments, bezel 20 includes a flange 23 extending outwardly from the outer wall of bezel 21.

In this way, the flange 23 can abut against the lower surface 14 of the touch panel 10, so that the connection area of the bezel 20 and the touch panel 10 can be increased, and the reliability of the fixed connection of the bezel 20 and the touch panel 10 is improved.

In addition, when the flange 23 abuts against the lower surface 14 of the touch panel 10 when the bezel 20 is fitted into the fitting hole 17 from below to above, it indicates that the bezel 20 has been fitted to a predetermined position. Thus, the provision of the flange 23 also improves the assembly efficiency of the input assembly 100, reducing the manufacturing cost of the input assembly 100.

In some embodiments, a sealing sheet may be provided between flange 23 and lower surface 14 to prevent water from entering terminal 1000 from a gap between bezel 20 and mounting hole 17, thereby enhancing the water resistance of terminal 1000.

As in the embodiment of fig. 3-5, the flange 23 is of unitary construction with the trim ring 21. In contrast, as in the embodiment of fig. 6 and 7, the flange 23 and the trim ring 21 are formed as separate bodies. Specifically, the trim ring 21 includes a socket 24, and the socket 24 is connected to the support rim 22. The flange 23 is fitted over the socket 24. The flange 23 and the bezel 21 are separately molded to reduce the difficulty in manufacturing the bezel 20, so that the uniformity of each bezel 20 can be improved when the bezels 20 are mass-produced.

It is noted that in some embodiments, the socket 24 may be formed with a via 24a for the first flexible circuit board 40 to pass through.

Specifically, the socket 24 includes a connecting edge 241 and a carrier plate 242. The connecting edge 241 connects the supporting edge 22 and the carrier 242, and the connecting edge 241 is substantially perpendicular to the supporting edge 22. The carrier plate 242 is substantially perpendicular to the connecting edge 241. The connecting edge 241 is provided with a via hole 24 a.

The socket 24 is hollow to partially or completely receive the fingerprint chip package 30. It is noted that in some embodiments, the fingerprint chip package 30 may be supported on the carrier plate 242.

Referring again to fig. 3-5, in some embodiments, the flange 23 is perpendicular to the outer wall 215 of the trim ring 21.

Thus, the bezel 20 is manufactured by a simple process, and a contact area with the touch panel 10 can be increased.

In some embodiments, the flange 23 includes a first protrusion 231 and a second protrusion 232 connected to the first protrusion 231, the first protrusion 231 includes a first portion 2311 and a second portion 2312, the second portion 2312 is connected to the first portion 2311 and the second protrusion 232, and the second portion 2312 is protruded from the first portion 2311 and the second protrusion 232.

After the bezel 20 is fitted into the mounting hole 17, the first portion 2311 and the second protrusion 232 extend in the longitudinal direction of the touch panel 10, and the second portion 2312 extends in the lateral direction of the touch panel 10.

Since the accommodating space in the lateral direction of the touch panel 10 is large, the second portion 2312 is protruded from the first portion 2311 and the second protrusion 232, so that the connection area between the flange 23 and the touch panel 10 can be increased.

In addition, the widths of the first portion 2311 and the second protruding portion 232 are small, so that the longitudinal length of the non-display region 16 of the touch panel 10 can be prevented from being increased due to the widths of the first portion 2311 and the second protruding portion 232, the ratio of the area of the display region 15 to the area of the touch panel 10 can be reduced, and the appearance of the terminal 1000 can be prevented from being affected.

In some embodiments, the top surface 231a of the first protrusion 231 is flush with the top surface 232a of the second protrusion 232, and the thickness of the first portion 2311 is greater than the thickness of the second protrusion 232.

It is understood that the second protrusion 232 is closer to the display area 15 than the first portion 2311 after the bezel 20 is fitted into the fitting hole 17. In other words, the first portion 2311 is disposed away from the display region 15, and the second protrusion 232 is disposed close to the display region 15.

Since there are many parts of the input unit 100 near the display region 15, the thickness of the second protrusion 232 is small, so that the second protrusion 232 can avoid interference with other parts near the display region 15 (as shown in fig. 2).

As shown in fig. 2, there is an overlapping portion between the bezel 20 and the orthographic projection of the second flexible circuit board 50 and other parts connected to the screen of the terminal 1000 on the lower surface 14 of the touch panel 10, and the thickness of the second protrusion 232 is thinner to avoid interference with the second flexible circuit board 50 and other parts, so that the bezel 20 can be disposed closer to the display region 15, and the bezel 20 can be disposed even partially or completely within the display region 15 of the touch panel 10 to reduce the ratio of the area of the non-display region 16 to the area of the touch panel 10 and increase the ratio of the area of the display region 15 to the area of the touch panel 10.

In some embodiments, the trim ring 21 is oblong, the outer wall 215 of the trim ring 21 includes two parallel straight segments 2151 and two curved segments 2152 connecting the two straight segments 2151, the first portion 2311 is disposed on one of the straight segments 2151, and the second portion 2312 is disposed on the two curved segments 2152.

Thus, the decoration ring 21 is beautiful. Specifically, the two curved sections 2152 are aligned in the lateral direction of the touch panel 10 (left and right directions in fig. 1), and the two straight sections 2151 are aligned in the longitudinal direction (perpendicular to the lateral direction) of the touch panel 10.

In some embodiments, the shape of the second portion 2312 matches the shape of the curved segment 2152.

For example, the outer profile of the second portion 2312 is also circular arc-shaped and is disposed substantially concentric with the curved section 2152. This makes the bezel 20 more compact.

Referring to fig. 8-10, in some embodiments, the fingerprint chip package structure 30 includes a package body 31 and a fingerprint identification chip 32.

The package 31 includes a second bottom 311 and a side 312 connected to the second bottom 311, and a recess 33 is formed at a connection between the second bottom 311 and the side 312. The fingerprint recognition chip 32 is disposed within the package body 31.

In the fingerprint chip package structure 30 according to the embodiment of the present invention, the concave portion 33 may be matched with the supporting edge 22 in the decoration ring 20, so as to position the fingerprint chip package structure 30, thereby improving the assembling efficiency of the fingerprint chip package structure 30.

In addition, the concave portion 33 and the supporting edge 22 cooperate to reduce the thickness of the fingerprint chip package 30, which is beneficial to miniaturizing the terminal 1000 using the fingerprint chip package 30.

Specifically, when the user performs an operation of unlocking the terminal 1000 by using a fingerprint, the user may place a finger at a position corresponding to the fingerprint identification chip 32. The signal of the fingerprint identification chip 32 penetrates through the package 31 to collect and identify the fingerprint pattern of the user, the fingerprint pattern of the user is matched with the pre-stored fingerprint pattern, and if the matching is successful, the terminal 1000 is unlocked.

It will be appreciated that the surface of the fingerprint identification chip 32 facing the user's finger is provided with an array of sensing pixels to capture the user's fingerprint pattern. The package 31 encapsulates the fingerprint identification chip 32, so that the influence of other interference signals on the sensing pixel array during fingerprint pattern collection can be reduced, and the identification accuracy can be improved.

It should be noted that the recess 33 is used to cooperate with the supporting edge 22 so that the fingerprint chip package 30 is supported on the supporting edge 22 through the recess 33.

The recess 33 cooperates with the support rim 22, i.e. the support rim 22 is received in the recess 33.

In the present embodiment, the recess 33 has a ring-shaped configuration, and accordingly, the support rim 22 has a ring-shaped configuration so that the recess 33 can receive the support rim 22.

In other embodiments, the recessed portion 33 may be a plurality of recessed portions 33 circumferentially spaced around the junction of the second bottom surface 311 and the side surface 312, and correspondingly, the supporting edge 22 is also a plurality of supporting edges 22 circumferentially spaced around the junction, and the plurality of recessed portions 33 are correspondingly matched with the plurality of supporting edges 22.

For example, the number of the recessed portions 33 is 3, two adjacent recessed portions 33 are arranged at an interval of 120 degrees around the circumferential direction, and the number of the support edges 22 is also 3, and corresponds to the 3 recessed portions in the structural position.

It should be noted that the shape and number of the recessed portions 33 are not limited to the above-discussed case, as long as the recessed portions 33 cooperate with the supporting edge 22 so that the supporting edge 22 can support the fingerprint chip package 30, and therefore, the above-mentioned examples should not be construed as limiting the present invention.

Of course, in other embodiments, when the thickness of the fingerprint chip package 30 is relatively thin, the recess 33 of the fingerprint chip package 30 may be omitted.

In some embodiments, the package body 31 includes a first package portion 313 and a second package portion 314 connected to the first package portion 313, the first package portion 313 includes a second bottom surface 311, and the second package portion 314 includes a side surface 312.

As such, the first encapsulant 313 and the second encapsulant 314 may form the recess 33. The package 31 may be formed by cutting off the material of the package 31 to form the recess 33, or may be formed by connecting the first package portion 313 and the second package portion 314.

It is understood that, in order to form the recess 33, the cross-sectional area of the first encapsulation 313 is smaller than that of the second encapsulation 314.

In some embodiments, the first encapsulation portion 313 passes through the avoiding hole 222, and the second encapsulation portion 314 is supported on the supporting edge 22.

In some embodiments, the fingerprint identification chip 32 is disposed within the first package 313.

Thus, the circuit contacts of the fingerprint identification chip 32 are easily exposed for connection with the first flexible circuit board 40.

In some embodiments, the shape and size of the first packaging portion 313 matches the shape and size of the fingerprint identification chip 32.

Alternatively, the shape of the fingerprint identification chip 32 is similar to or the same as that of the first package portion 313, for example, the fingerprint identification chip 32 has a rectangular parallelepiped shape, and the first package portion 313 has a rectangular parallelepiped shape or a rounded rectangular parallelepiped shape.

The first packaging part 313 has a size slightly larger than that of the fingerprint identification chip 32 to achieve the effect of packaging the fingerprint identification chip 32. Therefore, the structure of the fingerprint chip package structure 30 can be made more compact.

In some embodiments, the first encapsulant 313 is shaped as a rounded rectangular parallelepiped.

Thus, the first package 31 and the fingerprint identification chip 32 can be well matched. Further, the shape of the first encapsulation portion 313 matches the shape of the avoiding hole 222, that is, the shape of the avoiding hole 222 is also a rounded rectangular parallelepiped.

In some embodiments, the second package portion 314 includes a top surface 3141 coupled to the side surface 312, and the fingerprint chip package structure 30 includes a cover plate 34 secured to the top surface 3141 of the second package portion 314. For example, the cover plate 34 is fixed to the top surface 3141 of the second package portion 314 by glue.

The user may press a finger on the overlay 34 while performing a fingerprint recognition operation. The cover plate 34 can protect the package body 31 from damage, so as to improve the reliability of the fingerprint chip package structure 30.

The cover plate 34 may be made of a material having a relatively high hardness, such as the sapphire material mentioned above, since the cover plate 34 is often touched.

In some embodiments, the cover plate 34 is shaped and sized to mate with the shape and size of the top surface 3141 of the second package portion 314.

For example, the top surface 3141 is oblong in shape, and the cover plate 34 is also oblong in shape. The area of the cover plate 34 is slightly larger than the area of the top surface 3141 of the second package portion 314. Thus, the cover plate 34 may completely cover the second encapsulation 314.

In some embodiments, a seal 60 is disposed between the second encapsulant 314 and the support rim 22, the seal 60 sealing a gap between the second encapsulant 314 and the support rim 22. The seal 60 is made of, for example, silicone (as shown in fig. 2).

Thus, the sealing member 60 can prevent foreign matters such as water and dust from entering the terminal 1000 from the gap between the fingerprint chip package structure 30 and the bezel 20, thereby improving the waterproof and dustproof effects of the terminal 1000.

In some embodiments, the recess 33 includes a first face 331 and a second face 332 connecting the first face 331, and the first face 331 is perpendicular to the second face 332.

Thus, the recess 33 is easily formed, and the first surface 331 is easily connected to the support rim 22. The first surface 331 and the second surface 332 are perpendicular to each other so that the package body 31 has a step shape.

Specifically, the seal 60 is disposed between the first face 331 and the support rim 22.

In some embodiments, the junction of the first and

second faces

331, 332 is rounded.

Thus, defects such as cracks are less likely to occur at the joint of the first surface 331 and the second surface 332, and the recessed portion 33 is easily formed.

Referring to fig. 2, 10 and 11, in some embodiments, the input assembly 100 includes a reinforcing plate 70 and a fixing plate 80. The stiffener 70 is formed with a first locating structure 72. The first flexible circuit board 40 is fixedly disposed on the reinforcing plate 70. The fixing plate 80 is formed with a second positioning structure 82, and the first positioning structure 72 cooperates with the second positioning structure 82 to limit the movement of the reinforcing plate 70 relative to the fixing plate 80.

Therefore, the first positioning structure 72 and the second positioning structure 82 cooperate to limit the movement of the reinforcing plate 70 relative to the fixing plate 80, so as to limit the movement of the fingerprint chip packaging structure 30, which is beneficial to the installation process of the fingerprint chip packaging structure 30.

For example, after the movement of the fingerprint chip package structure 30 is limited, glue may be applied to the gap between the fingerprint chip package structure 30 and the decoration ring 20 to fixedly bond the fingerprint chip package structure 30 and the decoration ring 20, so that the position of the fingerprint chip package structure 30 is fixed.

Specifically, the fingerprint chip package structure 30 and the stiffener 70 are respectively disposed on two opposite surfaces of the first flexible circuit board 40. The fixing plate 80 is disposed under the reinforcing plate 70. In assembling the input assembly 100, the fixing plate 80 can be fixed on the terminal 1000, and then the stiffener 70 with the fingerprint chip package 30 can be mounted on the fixing plate 80 by the first positioning structure 72 and the second positioning structure 82.

In order to secure the strength of the reinforcing plate 70, the reinforcing plate 70 may be made of a metal material, such as stainless steel.

In some embodiments, the number of first locating structures 72 is plural, and the number of second locating structures 82 corresponds to the number of first locating structures 72.

As such, the first positioning structures 72 and the second positioning structures 82 cooperate to further limit the movement of the stiffener 70, and thus the movement of the fingerprint chip package 30.

In some embodiments, the reinforcing plate 70 includes a mounting portion 74 and a connecting portion 76 connected to the mounting portion 74, the first flexible circuit board 40 is fixedly disposed on the mounting portion 74, and the connecting portion 76 is formed with the first positioning structure 72.

In this way, the connection portion 76 can protrude out of the first flexible circuit board 40, and the first positioning structure 72 formed on the connection portion 76 can be prevented from interfering with the first flexible circuit board 40. Preferably, the mounting portion 74 and the connecting portion 76 are integrally formed.

In some embodiments, the number of the connecting portions 76 is two, two connecting portions 76 are respectively connected to two opposite ends of the mounting portion 74, and each connecting portion 76 is formed with the first positioning structure 72.

The first positioning structures 72 are formed on the connecting portions 76 at the two opposite ends of the mounting portion 74, so that after the first positioning structures 72 are matched with the second positioning structures 82, the stress of the reinforcing plate 70 is more uniform, and the reliability of connection between the reinforcing plate 70 and the fixing plate 80 is improved.

In some embodiments, the first positioning structure 72 includes a bump 721, the second positioning structure 82 is formed with a card hole 821 matching with the bump 721, and the bump 721 is received in the card hole 821.

Thus, the structure of the first positioning structure 72 and the structure of the second positioning structure 82 are simple, so that the reinforcing plate 70 and the fixing plate 80 are easy to manufacture, and the manufacturing cost of the input assembly 100 can be reduced.

Note that, as in the example of fig. 12, the card hole 821 is a through hole. In other embodiments, the card hole 821 may be a blind hole.

It will be appreciated that in other embodiments, the first locating feature 72 is formed with a snap-fit aperture and the second locating feature 82 includes a projection that mates with the snap-fit aperture, the projection being received in the snap-fit aperture.
