Connector production method, female connector, and interface-equipped device

Abstract

The application relates to a connector production method, a female end connector and a device with an interface, and the connector production method comprises the following steps: performing one-time injection encapsulation on a first terminal piece to form a limiting part; under the limiting action of the limiting part, a second terminal piece keeps a predetermined position relative to the first terminal piece; and performing two-time injection encapsulation on the second terminal piece and the limiting part. After the first terminal pieces are arranged in a first predetermined form, one-time injection material is injected into a space containing the first terminal pieces, and the first terminal pieces are covered to a certain extent. After the shape of the one-time injection material is fixed, the limiting part can limit the second terminal piece, so that the second terminal piece keeps a predetermined position relative to the first terminal piece. Two-time injection material covers the second terminal piece and the limiting part, thereby reducing the injection times and the overall thickness of the injection part, and providing space for increasing the thickness of the first terminal piece or the second terminal piece.

Description

Technical Field

[0001] This invention relates to the field of connector technology, and in particular to a method for manufacturing a female connector, a female connector, and an interface device. Background Technology

[0002] Connectors are required in mobile phones, laptops, chargers, power banks, or other devices with interfaces to transmit electrical energy or signals. For example, mobile phones have a female connector. When the male connector of the charging cable is inserted into the female connector of the mobile phone, the mobile phone and the charger can communicate to match the appropriate charging protocol and input the appropriate charging voltage or charging current to the mobile phone.

[0003] Devices with interfaces primarily transmit electrical energy or signals to external devices such as chargers through the terminals of connectors. The injection-molded portion of the connector provides positioning and insulation protection for the terminals. To handle larger charging currents, the terminals need to be thicker to reduce resistance. Since the size of the connector housing is generally limited by specifications, increasing the terminal thickness necessitates reducing the thickness of the injection-molded portion. However, reducing the thickness of the injection-molded portion can negatively impact the quality of the molding process, leading to a lower product yield for the connector. Summary of the Invention

[0004] Therefore, it is necessary to provide a connector manufacturing method, a female connector, and an interface device to address the problem that the injection molding process limits the thickness of the terminals.

[0005] A connector manufacturing method includes the following steps:

[0006] The first terminal component is encapsulated by a single injection molding process to form a defined portion.

[0007] The second terminal piece maintains a predetermined position relative to the first terminal piece under the limiting action of the limiting part;

[0008] The second terminal component and the defined portion are then subjected to secondary injection molding encapsulation.

[0009] In the aforementioned connector manufacturing method, after the first terminal pieces are arranged in a first predetermined configuration, a primary injection molding material is injected into the space accommodating the first terminal pieces, thus covering them to a certain extent. Under the shaping action of the accommodating space, the primary injection molding material is molded into a limiting portion. After the shape of the primary injection molding material is fixed, the limiting portion can limit the second terminal piece, maintaining it in a predetermined position relative to the first terminal piece. After the second and first terminal pieces are accommodated in another space, a secondary injection molding material is injected into that space, simultaneously covering the second terminal piece and the limiting portion. After the secondary injection molding material is formed, the second terminal piece can maintain a fixed positional relationship relative to the first terminal piece. Since the encapsulation and fixation of the second and first terminal pieces are achieved through only two injection molding processes, the number of injection molding operations is reduced, the overall thickness of the injection-molded portion is decreased, and space is provided for increasing the thickness of either the first or second terminal piece.

[0010] In one embodiment, during the secondary injection molding encapsulation of the second terminal and the defined portion, the molded part in the primary injection molding encapsulation is also encapsulated.

[0011] In one embodiment, during the primary injection molding of the first terminal piece to form the defined portion, a portion of the primary injection molding material is injected into a position that can be surrounded by the centering clip.

[0012] In one embodiment, the second terminal piece maintains the predetermined position relative to the first terminal piece under the mating action of the limiting portion, the second terminal piece and the limiting portion are mutually restrained by form fit, and / or the second terminal piece is maintained on the other side of the partition portion relative to the first terminal piece.

[0013] A female connector, comprising:

[0014] First terminal piece, a plurality of first terminal pieces arranged in a first predetermined pattern;

[0015] A first molded part is used to encapsulate the first terminal piece; the first molded part is provided with a limiting portion;

[0016] A second terminal piece is connected to the limiting portion; a plurality of second terminal pieces are arranged in a second predetermined pattern under the limiting effect of the limiting portion; and

[0017] The second molded component is used to encapsulate the first molded component and the second terminal component.

[0018] In the aforementioned female connector, the first molded part connects with the first terminal pieces, maintaining the arrangement of the first terminal pieces along a first predetermined pattern. The first molded part has a limiting portion that can mate with the second terminal pieces. Before the second terminal pieces are covered by secondary injection molding material, the multiple second terminal pieces are arranged along a second predetermined pattern under the limiting action of the limiting portion. After the secondary injection molding material is molded into the second molded part, the second molded part maintains a fixed positional relationship between the first and second terminal pieces. Because the female connector utilizes the first and second molded parts to achieve the encapsulation and fixation of the second and first terminal pieces, the number of injection molding processes can be reduced, the overall thickness of the injection-molded portion can be reduced, and space can be provided for increasing the thickness of the first or second terminal pieces.

[0019] In one embodiment, a first groove is formed on the defining portion; the first depth direction of the first groove is parallel to the baseline; the second terminal is partially accommodated in the first groove.

[0020] In one embodiment, the second terminal member has a first protrusion that is accommodated in the first groove.

[0021] In one embodiment, the second terminal member has a strip-shaped portion; the strip-shaped portion is accommodated between two adjacent defining portions.

[0022] In one embodiment, the first molded part has a barrier portion; the barrier portion is disposed on the side of the first molded part opposite to the first terminal member; the barrier portion is used to keep two adjacent second terminal members separated.

[0023] An interface device includes: a female connector. Attached Figure Description

[0042] The technical solutions provided by the embodiments of the present invention are described below with reference to the accompanying drawings.

[0043] This invention provides a device with an interface.

[0044] In some implementations, combined Figure 2 and Figure 3 As shown, the interfaced device has a female connector 100. The female connector 100 is capable of mating with a male connector. The interfaced device is a device that can input electrical energy, output electrical energy, input signals, or output signals through the female connector 100. Specifically, the interfaced device includes a mobile phone, a laptop, a charger, a power bank, or other device with a female connector 100. Further, the female connector 100 is electrically connected to a circuit board within the interfaced device to transmit signals or electrical energy. More specifically, the female connector 100 is fixed relative to the circuit board within the interfaced device by soldering.

[0045] Combination Figures 2 to 11 As shown, the present invention provides a female connector 100.

[0046] In some implementations, the female connector 100 is a Type-C female connector.

[0047] In some implementations, combined Figure 4 , Figure 5 and Figure 9 As shown, the female connector 100 includes a first terminal piece 20, a first molded piece 30, a second terminal piece 40, and a second terminal piece 40. A plurality of first terminal pieces 20 are arranged in a first predetermined configuration. The first molded piece 30 encapsulates the first terminal pieces 20 and has a limiting portion 31. The second terminal pieces 40 are connected to the limiting portion 31. A plurality of second terminal pieces 40 are arranged in a second predetermined configuration due to the limiting effect of the limiting portion 31. The second molded piece 50 encapsulates the first molded piece 30 and the second terminal pieces 40.

[0048] Specifically, the first molded part 30 is connected to the first terminal part 20, so that the first terminal parts 20 are arranged in a first predetermined pattern. The first molded part 30 is provided with a limiting part 31, which can mate with the second terminal part 40. Before the second terminal part 40 is covered by the secondary injection molding material, the multiple second terminal parts 40 are arranged in a second predetermined pattern under the limiting action of the limiting part 31. After the secondary injection molding material is molded into the second molded part 50, the second molded part 50 maintains a fixed positional relationship between the first terminal part 20 and the second terminal part 40. Since the female connector 100 uses the first molded part 30 and the second molded part 50 to achieve the encapsulation and fixation of the second terminal part 40 and the first terminal part 20, the number of injection molding processes can be reduced, the overall thickness of the injection molded part can be reduced, and space can be provided for increasing the thickness of the first terminal part 20 or the second terminal part 40.

[0049] Specifically, the injection-molded portion includes any structure formed by injection molding.

[0050] Specifically, according to the requirements of a single injection molding process, the thickness of the injection molding material coverage cannot be too thin; otherwise, the injection molding material will not be able to flow to narrow areas, resulting in gaps or incomplete coverage after the injection molding material is formed. When the thickness of the injection molding material coverage cannot be reduced, this invention reduces the number of injection molding processes, thereby preventing the first terminal 20 or the second terminal 40 from being covered by more than two layers of injection molding material, thus reducing the coverage thickness of the first terminal 20 or the second terminal 40. Furthermore, by increasing the thickness of the first terminal 20 or the second terminal 40, the quality of the molding process is prevented from being affected, ensuring the product qualification rate of the female connector 100.

[0051] Specifically, the encapsulation of the first molded component 30 on the first terminal component 20 can be understood as the first molded component 30 fixing the first terminal component 20 while maintaining insulation between the first terminal components 20. Specifically, the encapsulation of the first molded component 30 and the second terminal component 40 by the second molded component 50 can be understood as the second molded component 50 fixing the first molded component 30 and the second terminal component 40 together, while maintaining insulation between the non-conductive portions of the first terminal component 20 and the second terminal component 40 and the external environment.

[0052] In some implementations, combined Figures 4 to 7 As shown, the first terminal piece 20 has a first contact surface and a first inner cladding surface. A portion of the first contact surface of the first terminal piece 20 is used for electrical contact with the male connector, enabling the female connector 100 to transmit electrical energy or signals with the male connector. Another portion of the first contact surface of the first terminal piece 20 is used for connection with internal components of an interface device, more specifically, for soldering to the circuit board of the interface device.

[0053] In some implementations, combined Figure 6 , Figure 9 and Figure 11 As shown, the first terminal piece 20 has a first outer end portion 21 and a first inner end portion 22. Specifically, the first inner end portion 22 and the first outer end portion 21 each have a first contact surface. More specifically, the first outer end portion 21 is used for electrically connecting to a male connector, and the first inner end portion 22 is used for electrically connecting to internal components of an interface device.

[0054] In some implementations, combined Figure 6 As shown, for an arrangement along a first predetermined form, it can be understood that the main body portion of each first terminal piece 20 coincides with a reference plane or a plane parallel to the reference plane. Further, the first inner end portion 22 is located at a baseline. Specifically, when the male connector is inserted into the female connector 100, the insertion direction of the male connector is parallel to the centerline of the female connector 100. The distances from both ends of the female connector 100 to the centerline in the width direction are the same. Specifically, the reference plane is parallel to the centerline and also parallel to the female connector 100 in the width direction. In other embodiments, the first predetermined form can also be any arrangement that reduces the space occupied by the multiple first terminal pieces 20 while maintaining mutual insulation. In one embodiment, the main body portion of the first terminal piece 20 includes a first outer end portion 21.

[0055] In some implementations, combined Figure 7 , Figure 9 and Figure 10 As shown, the second terminal piece 40 has a second contact surface and a second inner surface. A portion of the second contact surface of the second terminal piece 40 is used for electrical contact with the male connector, enabling the female connector 100 to transmit electrical energy or signals with the male connector. Another portion of the second contact surface of the second terminal piece 40 is used for connection with internal components of an interface device, more specifically, for soldering to the circuit board of the interface device.

[0056] In some implementations, combined Figure 9 and Figure 10 As shown, the second terminal 40 has a second outer end portion 43 and a second inner end portion 44. Specifically, the second inner end portion 44 and the second outer end portion 43 each have a second contact surface. More specifically, the second outer end portion 43 is used for electrically connecting to a male connector, and the second inner end portion 44 is used for electrically connecting to internal components of an interface device. In one embodiment, the first inner end portion 22 and the second inner end portion 44 are used for soldering and fixing to the internal circuit board of the interface device.

[0057] In some implementations, combined Figure 8 and Figure 10As shown, the second terminal member 40 is provided with a strip-shaped portion 42. The strip-shaped portion 42 is accommodated between two adjacent limiting portions 31. Specifically, a plurality of limiting portions 31 are distributed along a direction parallel to the baseline, and a gap is provided between adjacent limiting portions 31. Since the strip-shaped portion 42 is accommodated between two adjacent limiting portions 31, the strip-shaped portion 42 passes through the gap between the two limiting portions 31. In the direction parallel to the baseline, the position of the strip-shaped portion 42 is restricted by the two adjacent limiting portions 31, thereby keeping the position of the second terminal member 40 stable. Furthermore, by restricting the strip-shaped portion 42 by the limiting portions 31, a portion of the second inner end portion 44 can maintain the required spacing distance with the adjacent first inner end portion 22. More specifically, the width of the strip-shaped portion 42 corresponds to the size of the gap between the two adjacent limiting portions 31, thereby ensuring that the strip-shaped portion 42 can be stably maintained between the two adjacent limiting portions 31.

[0058] In some embodiments, for an arrangement along a second predetermined form, it can be understood that the main body portion of each second terminal 40 coincides with a reference plane or with a plane parallel to the reference plane. Further, the second inner end portion 44 is located at a baseline.

[0059] In some implementations, combined Figure 6 and Figure 7 As shown, the first molded part 30 also has a partition part 32 connected to the limiting part 31. When the female connector 100 mates with the male connector, the partition part 32 is inserted into the male connector. The first outer end part 21 and the second outer end part 43 are respectively arranged on both sides of the partition part 32. Further, the first outer end part 21 is partially covered by the first molded part 30, and the first contact surface of the first outer end part 21 is exposed outside the partition part 32.

[0060] In some implementations, combined Figure 9 and Figure 11 As shown, a first groove 311 is formed on the limiting portion 31. The first depth direction of the first groove 311 is parallel to the baseline. The second terminal 40 is partially accommodated in the first groove 311. Specifically, a plurality of first inner ends 22 and a plurality of second inner ends 44 are located at the baseline to effectively control the volume. Since the first depth direction of the first groove 311 is parallel to the baseline, and the opposite direction of the first depth direction points to another limiting portion 31, after the second terminal 40 is partially accommodated in the first groove 311, the movement of the second terminal 40 in the direction perpendicular to the baseline can be restricted by the abutment between the second terminal 40 and the inner wall of the first groove 311, thereby keeping the second inner ends 44 of the second terminal 40 aligned with the baseline. During the secondary injection molding process, the displacement of the second inner ends 44 in the direction perpendicular to the baseline can be avoided.

[0061] In some implementations, combined Figure 8 and Figure 10 As shown, the second terminal piece 40 is provided with a first protrusion 41 that is accommodated in the first groove 311. Specifically, the first protrusion 41 abuts against the inner wall surface of the first groove 311, thereby restricting the movement of the second terminal piece 40 in a direction perpendicular to the baseline. More specifically, in a direction perpendicular to the baseline, the limiting portion 31 forms the inner wall surface of the first groove 311. Furthermore, there is an interference fit between the first protrusion 41 and the inner wall of the first groove 311, so that the inner wall surface of the first groove 311 exerts pressure on the first protrusion 41, causing the first protrusion 41 to be restricted within the first groove 311 under pressure, making it difficult for the second terminal piece 40 to detach from the limiting portion 31, and ensuring the positional stability of the second terminal piece 40 before the secondary injection molding and encapsulation is completed.

[0062] Furthermore, for the portion of the second molded part 50 near the first outer end 21 and the second outer end 43, in order to avoid affecting the thickness of this portion of the second molded part 50, combined with... Figure 9 and Figure 11 As shown, the limiting portion 31 is disposed on the first molded member 30 near the second inner end portion 44, so as not to affect the insertion of the partition portion 32 into the male connector. Furthermore, combined with... Figure 8 and Figure 11 As shown, the limiting part 31 is provided with an expansion surface 312, which is disposed at the opening edge of the first groove 311. The expansion surface 312 causes the opening of the first groove 311 to expand in the opposite direction along the second depth direction, so as to facilitate the first protrusion 41 to enter the first groove 311 along the second depth direction. Specifically, the expansion surface 312 is a straight surface or an arc surface.

[0063] In one implementation, combined Figure 10 As shown, the first protrusion 41 is connected to the strip 42, and the first protrusion 41 and the strip 42 cooperate to form a T-shaped structure parallel to the reference plane, thereby effectively ensuring the directional stability of the second terminal 40. Furthermore, the length of the first protrusion 41 in the direction parallel to the baseline is not less than 50% of the width of the strip 42, thereby forming a more stable limiting fit between the second terminal 40 and the limiting portion 31 with the first groove 311, ensuring the directional stability of the second terminal 40.

[0064] In some implementations, combined Figure 7 and Figure 9As shown, the first molded part 30 has a barrier portion 33. The barrier portion 33 is disposed on the side of the first molded part 30 facing away from the first terminal member 20. The barrier portion 33 is used to maintain a separation between two adjacent second terminal members 40. Specifically, the barrier portion 33 is connected to the partition portion 32 on the side facing away from the first terminal member 20. After the second terminal member 40 is mated with the limiting portion 31, before the secondary injection molding is completed, since the barrier portion 33 is between adjacent second terminal members 40, short circuits between adjacent second terminal members 40 can be avoided, thus preventing the function of the female connector 100 from being affected.

[0065] In some implementations, combined Figure 4 and Figure 5 As shown, a second molded member 50 perpendicular to the centerline surrounds the first molded member 30 and the second terminal member 40. More specifically, the second molded member 50 also extends partially into the gap between adjacent second terminal members 40.

[0066] In some implementations, combined Figure 2 and Figure 3 As shown, the female connector 100 also includes a housing 60, in which the second molded part 50 is housed. A gap is provided between the housing 60 and the partition portion 32 for accommodating the male connector.

[0067] In some implementations, combined Figure 7 and Figure 9 As shown, the female connector 100 also includes a center clip 70. The center clip 70 is fixedly connected to the first molded part 30. The second molded part 50 simultaneously surrounds and covers both the center clip 70 and the first molded part 30, thereby making the installation of the center clip 70 more reliable. Specifically, when the female connector 100 mates with the male connector, the center clip 70 provides a locking support, placing the female connector 100 and the male connector in a releasable mating locked state. More specifically, the center clip 70 includes a main piece 71 and an extension 72 connected to the main piece 71, the extension 72 being located on the side of the main piece 71 away from the centerline. Further, the female connector 100 forms a groove 73 on the side of the extension 72 away from the male connector, the groove 73 accommodating the elastic locking portion of the male connector, while the extension 72 creates a snap-fit ​​effect on the locking portion, thereby enabling a snap-fit ​​mating. The center clip 70 reinforces the edge of the female connector 100 near the slot 73. More specifically, the edge of the slot 73 is formed after the center clip 70 is subjected to secondary injection molding. Furthermore, the center clip 70 also serves to shield and increase overall strength.

[0068] This invention provides a connector manufacturing method.

[0069] In some implementations, combined Figure 1As shown, the connector manufacturing method includes the following steps:

[0070] S10: Perform a one-time injection molding encapsulation on the first terminal piece 20 to form the limiting part 31;

[0071] S20: The second terminal 40 is kept in a predetermined position relative to the first terminal 20 under the limiting action of the limiting part 31;

[0072] S30: Perform secondary injection molding encapsulation on the second terminal 40 and the limiting part 31.

[0073] Specifically, after the first terminal pieces 20 are arranged in a first predetermined pattern, primary injection molding material is injected into the space accommodating the first terminal pieces 20, thus covering the first terminal pieces 20 to a certain extent. Under the shaping action of the accommodating space, the primary injection molding material is shaped into the limiting portion 31. Combined with... Figure 7 As shown, after the shape of the primary injection molding material is fixed, the limiting part 31 can limit the second terminal 40, keeping the second terminal 40 in a predetermined position relative to the first terminal 20. After the second terminal 40 and the first terminal 20 are housed in another space, secondary injection molding material is injected into that space, simultaneously covering the second terminal 40 and the limiting part 31. After the secondary injection molding material is formed, the second terminal 40 can maintain a fixed positional relationship relative to the first terminal 20. Since the encapsulation and fixation of the second terminal 40 and the first terminal 20 are achieved through only two injection molding processes, the number of injection moldings can be reduced, the overall thickness of the injection-molded part can be reduced, and space can be provided for increasing the thickness of the first terminal 20 or the second terminal 40.

[0074] For step S10, in some embodiments, primary injection molding encapsulation involves injecting primary injection molding material into the space housing the first terminal 20. Specifically, after the first terminal 20 is housed in the first mold, primary injection molding material is injected into the first mold. Figure 11 As shown, the first mold is configured to mold a portion of one-time injection material into the shape of a limiting part 31. Combined with... Figure 9 As shown, after the primary injection molding material cools and solidifies, a first molded part 30 is formed, and a limiting portion 31 is formed. A portion of the primary injection molding material is injected between two adjacent first terminal pieces 20, so that the two adjacent first terminal pieces 20 are insulated from each other. After the primary injection molding material cools and solidifies, the position of the first terminal piece 20 is limited by the first molded part 30, so that any two first terminal pieces 20 maintain a fixed relative position.

[0075] In some embodiments, a portion of the primary injection molding material is injected into a position that surrounds the center clip 70. Specifically, the center clip 70 is also defined in the first mold. After the first terminal 20 is encapsulated by primary injection molding, the position of the center clip 70 relative to the first terminal 20 is defined, thereby avoiding the need for additional injection molding processes to fix the center clip 70 relative to the first molded part 30 and the second molded part 50. This helps to reduce the number of injection molding processes and provides space for increasing the thickness of the first terminal 20 or the second terminal 40. Since the first inner surface of the first terminal 20 does not need to make electrical contact with other devices, the primary injection molding material covers the first inner surface of the first terminal 20, thereby keeping the first inner surface insulated from other devices.

[0076] For step S20, combined with Figure 7 and Figure 9 As shown, in some embodiments, the second terminal 40 and the limiting portion 31 are positioned by a form fit. Specifically, after the injection-molded material cools into the first molded part 30, the second terminal 40 is assembled to the first molded part 30. Under the limiting effect of the limiting portion 31, the orientation of each second terminal 40 on the reference surface remains stable. Specifically, the second terminal 40 and the reference surface have a large intersection area. In one embodiment, by forming a first protrusion 41 on the second terminal 40 and a first groove 311 on the limiting portion 31, the first groove 311 can just accommodate the first protrusion 41, thereby creating a form fit between the second terminal 40 and the limiting portion 31. In another embodiment, by forming a second groove on the second terminal 40 and the limiting portion 31 being convex, the second groove can just accommodate the protruding portion of the limiting portion 31, thereby creating a form fit between the second terminal 40 and the limiting portion 31.

[0077] In some implementations, combined Figure 6 and Figure 7 As shown, for the second terminal 40 to maintain a predetermined position relative to the first terminal 20, it can be understood that the second terminal 40 is held on the other side of the partition portion 32 relative to the first terminal 20. Since the partition portion 32 is insulating, it can maintain insulation between the second terminal 40 and the first terminal 20.

[0078] For step S30, in conjunction with Figures 4 to 7As shown, in some embodiments, after the first molded part 30 and the second terminal part 40 are housed in the second mold, secondary injection molding material is injected into the second mold. The second mold is configured to mold the secondary injection material into the shape of the second molded part 50. The secondary injection material forms the second molded part 50 after cooling and solidification. A portion of the secondary injection material is injected between two adjacent second terminal parts 40, thereby insulating the two adjacent second terminal parts 40 from each other. After the secondary injection material cools and solidifies, the position of the second terminal parts 40 is fixed by the second molded part 50, maintaining a fixed relative position between any two second terminal parts 40.

[0079] In some embodiments, during the secondary injection molding encapsulation of the second terminal 40 and the limiting portion 31, the molded component from the primary injection molding encapsulation is also encapsulated; specifically, the first molded component 30 is also encapsulated. Since the first molded component 30 and the second terminal 40 are integrally covered and fixed during the secondary injection molding encapsulation, the uniformity of the secondary injection molding encapsulation is improved, resulting in a more stable overall structure.

[0080] Specifically, since the second inner surface of the second terminal piece 40 does not need to make electrical contact with other devices, the secondary injection molding material covers the second inner surface of the second terminal piece 40, thereby ensuring that the second inner surface remains insulated from other devices. Furthermore, the secondary injection molding material can also cover a portion of the first inner surface.

[0081] In the connector manufacturing process, the second molded part 50 is finally housed in the housing 60. Specifically, the second molded part 50 is inserted into the housing 60 from one end.

[0082] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0083] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
