Description

TECHNICAL FIELD

[0001] The utility model relates to vehicle technical field, concretely relates to connecting terminal, circuit board subassembly and vehicle. BACKGROUND

[0002] The vehicle usually uses the PCB board to realize the effective communication between each device inside the vehicle, and the PCB board is connected with each device inside the vehicle through the connector terminal and the connecting wire. In the related art, after the connector terminal is inserted into the through hole, the position of the connector terminal needs to be adjusted to ensure the electrical connection between the connector terminal and the PCB board, and the installation process is very inconvenient.

[0003] The prior art CN114914724A discloses a conductive terminal and an electrical connector, and the conductive terminal can form electrical contact with the PCB board through the first elastic arm and the elastic force generated when being compressed. However, the installation process of connecting the conductive terminal and the PCB board is still inconvenient. UTILITY MODEL CONTENTS

[0004] The application provides a connecting terminal, a circuit board subassembly and a vehicle to solve the problem of inconvenient installation of the connector terminal and the PCB board. The technical scheme adopted by the utility model is as follows:

[0005] According to a first aspect of the application, a connecting terminal is provided for connecting with a circuit board, and the circuit board is provided with a through hole. The connecting terminal includes a main body part and a limiting part. The main body part has a first connecting end and a second connecting end, and the first connecting end is used for connecting to the through hole. The limiting part is connected to the main body part and located between the first connecting end and the second connecting end. In the case where the first connecting end is connected to the through hole, the limiting part is used for contacting the side surface of the circuit board facing the second connecting end.

[0006] Through the above arrangement, the connecting terminal can be connected with the through hole through the first connecting end, and then the connection between the connecting terminal and the circuit board is realized. In the process of connecting the connecting terminal and the circuit board, part of the first connecting end can be inserted into the through hole first, and then the limiting part is pushed to move towards the circuit board, until the limiting part contacts the circuit board. At this time, the circuit board can limit the movement of the limiting part towards the circuit board, and then limit the movement of the connecting terminal, so as to position the connecting terminal.

[0007] In this way, through the positioning effect of the limiting part on the first connecting end, in the process of connecting the connecting terminal and the circuit board, only the first connecting end needs to be inserted into the through hole and the first terminal needs to be pushed, until the limiting part contacts the circuit board, and then the connection between the connecting terminal and the circuit board can be connected. It is not necessary to adjust the position of the connecting terminal, so as to simplify the connection process of the connecting terminal and the circuit board, and facilitate the connection of the connecting terminal and the circuit board.

[0008] In a possible implementation, the connecting terminal comprises a plurality of limiting portions, which are arranged around the arrangement direction of the first connecting end and the second connecting end.

[0009] Through the above arrangement, the plurality of limiting portions can simultaneously contact the circuit board and position the first connecting end, so that the stability of the contact between the limiting portions and the circuit board can be improved, the part of the connecting terminal extending into the through hole is prevented from being too much, and the positioning effect of the limiting portions on the first connecting end is ensured, and the connection between the connecting terminal and the circuit board is further facilitated.

[0010] In a possible implementation, the first connecting end comprises a body and a supporting portion. The supporting portion is connected to one side of the body in a first direction, and the first direction is perpendicular to the arrangement direction of the first connecting end and the second connecting end. The supporting portion is used for clamping the through hole.

[0011] Through the above arrangement, since the supporting portion is connected to one side of the body in the first direction and clamps the through hole, the body can be in interference fit with the through hole through the supporting portion, so that the connection between the first connecting end and the through hole is realized. Compared with the case where the shape of the first connecting end is a cylinder, when the first connecting end comprises the body and the supporting portion, the material required for machining the first connecting end can be reduced, and thus the machining cost of the connecting terminal is reduced.

[0012] In a possible implementation, the supporting portion is provided with a guide surface at an end away from the second connecting end. The distance between the guide surface and the body gradually increases in the direction of the body towards the second connecting end.

[0013] Through the above arrangement, in the process of connecting the connecting terminal and the circuit board, since the distance between the guide surface and the body gradually increases in the direction of the body towards the second connecting end, when the guide surface contacts the edge of the through hole away from the second connecting end, the guide surface can guide the body, so that the body can be installed and positioned to ensure the accuracy of the position of the body installation.

[0014] In a possible implementation, the supporting portion is connected with the limiting portion.

[0015] Through the above arrangement, the limiting portion can support the supporting portion, so that the supporting portion can be more stably connected to the body. In this way, the structural strength of the connecting terminal as a whole can be improved, and thus the stability of the connection between the connecting terminal and the circuit board is further improved.

[0016] In a possible implementation, the first connecting end comprises a plurality of supporting portions, and the plurality of supporting portions are connected with the body.

[0017] Through the above arrangement, the plurality of support portions can be jointly clamped in the through hole. Compared with the first connecting end including only one support portion, when the number of support portions is multiple, the first connecting end and the through hole can be more stably interference-fitted together. In this way, the stability of the connection between the first connecting end and the through hole can be improved, and the stability of the connection between the connecting terminal and the circuit board can be improved.

[0018] In a possible implementation, the first connecting end further includes a guide portion connected to the side of the body opposite to the second connecting end. In the direction of the body toward the second connecting end, the area of the cross section of the guide portion perpendicular to the direction of the body toward the second connecting end gradually increases.

[0019] Through the above arrangement, in the process of connecting the connecting terminal and the circuit board, in the direction of the body toward the second connecting end, the radial dimension of the area of the cross section of the guide portion perpendicular to the direction of the body toward the second connecting end gradually increases. Therefore, when the guide portion contacts the end edge of the through hole close to the second connecting end, the guide portion can guide the body, so that the body can be positioned and installed, to further ensure the accuracy of the position of the installation of the body.

[0020] In a possible implementation, the end edge of the guide portion close to the body contacts the end edge of the body away from the second connecting end. And / or, the end edge of the guide surface away from the second connecting end contacts the body.

[0021] Through the above arrangement, in the process that the guide portion contacts the end edge of the through hole close to the second connecting end, the end edge of the through hole close to the second connecting end can slide along the outer surface of the guide portion relative to the guide portion until sliding to the end edge of the guide portion close to the second connecting end. And because the end edge of the guide surface away from the second connecting end contacts the body, in the process of connecting the connecting terminal and the circuit board, the support portion will not contact the side surface of the circuit board toward the second connecting end, that is, in the process of connecting the connecting terminal and the circuit board, the support portion will not block the movement of the connecting terminal, so that the normal connection of the connecting terminal and the circuit board is ensured.

[0022] According to a second aspect of the present application, a circuit board assembly is provided, including a circuit board and the above-described connecting terminal, and the connecting terminal is connected to the circuit board.

[0023] According to a third aspect of the present application, a vehicle is provided, including the above-described circuit board assembly.

[0024] Therefore, the above technical features of the present application have the following beneficial effects:

[0025] (1) The application sets the main body and the limiting part, the connecting terminal can be connected with the through hole through the first connecting end, and then connected with the circuit board. Through the positioning effect of the limiting part on the first connecting end, during the connection of the connecting terminal and the circuit board, only the first connecting end needs to be inserted into the through hole and the first terminal is pushed until the limiting part contacts the circuit board to connect the connecting terminal and the circuit board. It is not necessary to adjust the position of the connecting terminal, so as to simplify the connection process of the connecting terminal and the circuit board, and facilitate the connection of the connecting terminal and the circuit board.

[0026] (2) The application sets multiple limiting parts, which can improve the stability of the contact between the limiting part and the plate body, avoid too much part of the connecting terminal inserted into the through hole, and ensure the positioning effect of the limiting part on the first connecting end, thereby facilitating the connection of the connecting terminal and the plate body.

[0040] In order to make the ordinary people in the art better understand the technical solutions of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings.

[0041] It should be noted that the terms "first", "second", and the like in the specification and claims of the present application and the above-described drawings are used to distinguish similar objects, and do not necessarily have to be used to describe a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of devices and methods consistent with some aspects of the present application, as detailed in the appended claims.

[0042] The vehicle usually uses the PCB board to realize the effective communication between various devices inside the vehicle, and the PCB board is connected with various devices inside the vehicle through the connector terminal and the connecting line. In the related art, after the connecting terminal is inserted into the through hole, the position of the connecting terminal needs to be adjusted to ensure the electrical connection between the connecting terminal and the PCB board, and the installation process is very inconvenient.

[0043] Based on this, as Figure 1 shown, Figure 1 is the external structure schematic diagram of the vehicle, and the present application provides a vehicle 100, which comprises a circuit board assembly, and the circuit board assembly is used to connect with the devices in the vehicle 100 to realize the communication between the devices.

[0044] As shown in Figure 2 , Figure 2 is Figure 1 the external structure diagram of the board on the vehicle and the connecting terminal, the circuit board assembly includes a circuit board 20 and a connecting terminal 10, and the connecting terminal 10 is connected with the circuit board 20.

[0045] Specifically, as shown in Figure 2 , Figure 3 , Figure 3 is Figure 2 the external structure diagram of the connecting terminal, the circuit board 20 is provided with a through hole 21, and the connecting terminal 10 includes a main body part 1, the main body part 1 has a first connecting end 11 and a second connecting end 12, and the first connecting end 11 is used for connecting to the through hole 21.

[0046] Exemplarily, the circuit board 20 can be a PCB board, and can also be a backboard, a sub-board of a device.

[0047] It can be understood that the circuit board 20 can be provided with only one through hole 21, or can be provided with a plurality of through holes 21, and correspondingly, the circuit board assembly also includes a plurality of connecting terminals 10, and one connecting terminal 10 is connected with one through hole 21.

[0048] It can be understood that the material of the connecting terminal 10 can be a metal capable of conducting electricity, such as copper, iron, aluminum, etc.

[0049] Through the above arrangement, the connecting terminal 10 can be connected with the through hole 21 through the first connecting end 11, and then the connection between the connecting terminal 10 and the circuit board 20 is realized.

[0050] In some examples, the connecting terminal 10 is welded with the through hole 21, so that the connecting terminal 10 and the circuit board 20 can be stably connected together.

[0051] In some examples, the connecting terminal 10 is clamped with the through hole 21, so that when the connecting terminal 10 is installed on the circuit board 20, only the first connecting end 11 needs to be inserted into the through hole 21, and when the connecting terminal 10 is removed from the circuit board 20, only the connecting terminal 10 needs to be pulled out of the through hole 21. Compared with welding the connecting terminal 10 with the circuit board 20, the installation and disassembly of the connecting terminal 10 and the circuit board 20 can be facilitated.

[0052] At the same time, compared with welding the connecting terminal 10 with the circuit board 20, clamping the connecting terminal 10 with the circuit board 20 can avoid the short circuit, open circuit, poor contact and other faults of the circuit board 20 caused by virtual welding, welding slag and other faults in the welding process, thereby ensuring the normal use of the circuit board 20, and further ensuring the normal use of the vehicle 100.

[0053] In some examples, the circuit board 20 further comprises a mounting sleeve, which is arranged in the through hole 21 and connected with the circuit board 20, and the axial direction of the mounting sleeve is consistent with the axial direction of the through hole 21. The first connecting end 11 is arranged in the mounting sleeve and is clamped with the mounting sleeve.

[0054] Exemplarily, the material of the mounting sleeve can be silica gel, plastic or the like.

[0055] Through the above arrangement, the mounting sleeve can be clamped with the first connecting end 11 to realize the connection between the connecting terminal 10 and the circuit board 20. Moreover, the mounting sleeve can protect the through hole 21, so as to ensure that the current will not be disturbed when passing through, thereby improving the working performance and reliability of the circuit board 20.

[0056] In some examples, the second connecting end 12 is used to be connected with a connecting wire, one end of the connecting wire is connected with the second connecting end 12, and the other end of the connecting wire is used to be connected with a device, a power supply or the like, so as to realize the signal transmission and power transmission between the circuit board 20 and the device, the power supply or the like.

[0057] As shown in Figure 3 , Figure 4 , Figure 4 is Figure 2 the assembly structure diagram of the connecting terminal and the board body, the connecting terminal 10 further comprises a limiting part 2, which is connected with the main part 1 and located between the first connecting end 11 and the second connecting end 12. In the case that the first connecting end 11 is connected with the through hole 21, the limiting part 2 is used to be in contact with the side surface of the circuit board 20 which is towards the second connecting end 12.

[0058] Through the above arrangement, in the process of connecting the connecting terminal 10 and the circuit board 20, part of the first connecting end 11 can be firstly inserted into the through hole 21, and then the limiting part 2 is pushed to move towards the circuit board 20 until the limiting part 2 is in contact with the circuit board 20. At this time, the circuit board 20 can limit the movement of the limiting part 2 towards the circuit board 20, and further limit the movement of the connecting terminal 10, so as to position the connecting terminal 10.

[0059] In this way, through the positioning effect of the limiting part 2 on the first connecting end 11, in the process of connecting the connecting terminal 10 and the circuit board 20, only the first connecting end 11 needs to be inserted into the through hole 21 and the first terminal needs to be pushed until the limiting part 2 is in contact with the circuit board 20, so as to realize the connection between the connecting terminal 10 and the circuit board 20. The position of the connecting terminal 11 does not need to be adjusted, so as to simplify the connection process of the connecting terminal 10 and the circuit board 20, and facilitate the connection of the connecting terminal 10 and the circuit board 20.

[0060] In some embodiments, the connecting terminal 10 comprises a limiting part 2, which is arranged on one side of the main body part 1 and is in contact with the circuit board 20 to position the connecting terminal 10.

[0061] In some embodiments, the connecting terminal 10 comprises a limiting part 2, which is arranged around the main body part 1.

[0062] In some other embodiments, as shown in Figure 3 the connecting terminal 10 comprises a plurality of limiting parts 2, which are arranged around the arrangement direction of the first connecting end 11 and the second connecting end 12.

[0063] Exemplarily, the plurality of limiting parts 2 can be arranged at intervals or not.

[0064] Exemplarily, the number of the limiting parts 2 can be one, two, three, etc.

[0065] Exemplarily, the plurality of limiting parts 2 can be evenly distributed or not around the main body part 1.

[0066] Through the above arrangement, the plurality of limiting parts 2 can be in contact with the circuit board 20 at the same time and position the first connecting end 11, so as to improve the stability of the contact between the limiting part 2 and the circuit board 20, avoid the excessive insertion of the connecting terminal 10 into the through hole 21, and thus ensure the positioning effect of the limiting part 2 on the first connecting end 11, and further facilitate the connection between the connecting terminal 10 and the circuit board 20.

[0067] Exemplarily, the limiting part 2 comprises a limiting sheet, a limiting rod, etc.

[0068] Exemplarily, the limiting part 2 comprises a limiting block.

[0069] Through the above arrangement, compared with the limiting part 2 comprising a limiting sheet, a limiting rod, etc., when the limiting part 2 comprises a limiting block, the limiting part 2 has higher structural strength, so that the limiting part 2 can be more stably in contact with the circuit board 20 when the limiting part 2 is in contact with the circuit board 20, avoiding the continuous movement of the first connecting end 11, and thus further ensuring the positioning effect on the first connecting end 11.

[0070] Meanwhile, when the limiting part 2 comprises a limiting block, the processing of the limiting part 2 can be facilitated, and thus the processing and manufacturing of the connecting terminal 10 can be facilitated.

[0071] Exemplarily, the limiting part 2 and the main body part 1 can be a split structure, and the limiting part 2 and the main body part 1 are connected after being processed respectively.

[0072] Exemplarily, the limiting part 2 and the main body part 1 can be integrally formed, so as to improve the structural strength of the whole connecting terminal 10.

[0073] In some embodiments, the first connecting end 11 is in the shape of a cylinder, the through hole 21 is in the shape of a circle, and the diameter of the first connecting end 11 is slightly larger than the diameter of the through hole 21 (for example, the diameter of the first connecting end 11 is 3 mm, and the diameter of the through hole 21 is 2.9 mm, or the diameter of the first connecting end 11 is 2.5 mm, and the diameter of the through hole 21 is 2.3 mm).

[0074] In this way, the first connecting end 11 can be in interference fit with the through hole 21, so as to realize the clamping of the first connecting end 11 and the circuit board 20, and further realize the connection of the connecting terminal 10 and the circuit board 20.

[0075] In some embodiments, as shown in Figure 3 , Figure 5 , Figure 5 is a cross-sectional view of the connecting terminal and the board body in Figure 4 , the first connecting end 11 includes a body 111 and a supporting part 112. The supporting part 112 is connected to one side of the body 111 in a first direction (the X direction shown in Figure 5 ), and the first direction is perpendicular to the arrangement direction of the first connecting end 11 and the second connecting end 12. The supporting part 112 is used for clamping the through hole 21.

[0076] Exemplarily, the shape of the body 111 can be a cylinder, a prism, etc.

[0077] Exemplarily, the supporting part 112 and the body 111 can be a split structure, and the limiting part 2 and the main body part 1 are connected together after being processed respectively.

[0078] Exemplarily, the supporting part 112 and the body 111 can be integrally formed, so as to improve the structural strength of the whole first connecting end 11.

[0079] Through the above arrangement, since the supporting part 112 is connected to one side of the body 111 in the first direction and clamps the through hole 21, the body 111 can be in interference fit with the through hole 21 through the supporting part 112, so as to realize the connection of the first connecting end 11 and the through hole 21.

[0080] Compared with the case that the shape of the first connecting end 11 is a cylinder, when the first connecting end 11 includes the body 111 and the supporting part 112, the material required for processing the first connecting end 11 can be reduced, so as to reduce the processing cost of the connecting terminal 10.

[0081] In some examples, along the first direction, the maximum size of the whole of the supporting part 112 and the body 111 is slightly larger than the radial size of the through hole 21 (for example, the maximum size of the whole of the supporting part 112 and the body 111 is 3.2 mm, and the diameter of the through hole 21 is 3 mm).

[0082] In this way, the first connecting end 11 can be interference-fitted with the through hole 21 through the support portion 112 and the body 111, so as to realize clamping of the support portion 112 and the through hole 21.

[0083] Exemplarily, the first connecting end 11 can include only one support portion 112.

[0084] Exemplarily, as shown in Figure 3 , the first connecting end 11 includes a plurality of support portions 112, and each of the plurality of support portions 112 is connected with the body 111.

[0085] Through the above arrangement, the plurality of support portions 112 can be clamped in the through hole 21 together. Compared with the first connecting end 11 including only one support portion 112, when the number of support portions 112 is more than one, the first connecting end 11 and the through hole 21 can be more stably interference-fitted together. In this way, the stability of the connection between the first connecting end 11 and the through hole 21 can be improved, and the stability of the connection between the connecting terminal 10 and the circuit board 20 can be further improved.

[0086] Exemplarily, the number of support portions 112 can be two, three, four, etc.

[0087] Exemplarily, the plurality of support portions 112 can be arranged at intervals around the body 111, or can be arranged without intervals around the body 111.

[0088] Exemplarily, the plurality of support portions 112 can be uniformly distributed around the body 111, or can be arranged non-uniformly around the body 111.

[0089] On this basis, in some embodiments, the support portion 112 is connected with the limiting portion 2.

[0090] Through the above arrangement, the limiting portion 2 can support the support portion 112, so that the support portion 112 can be more stably connected on the body 111. In this way, the structural strength of the connecting terminal 10 as a whole can be improved, and the stability of the connection between the connecting terminal 10 and the circuit board 20 can be further improved.

[0091] Specifically, in some examples, as shown in Figure 3 , Figure 4 , along the arrangement direction of the first connecting end 11 and the second connecting end 12, one end of the support portion 112 is connected with the limiting portion 2, and the other end of the support portion 112 is located on the side of the circuit board 20 away from the limiting portion 2.

[0092] Through the above arrangement, since the limiting portion 2 is located on the side of the circuit board 20 facing the second connecting end 12, and one end of the support portion 112 is connected with the limiting portion 2, the support portion 112 can be arranged in the through hole 21.

[0093] In this way, the support portion 112 has a longer length along the arrangement direction of the first connecting end 11 and the second connecting end 12, and is in contact with the inner wall surface of the through hole 21, so that the support portion 112 can be more stably supported between the body 111 and the inner wall surface of the through hole 21, thereby further improving the stability of the connection between the connecting terminal 10 and the circuit board 20.

[0094] In some embodiments, as shown in Figure 5 the support portion 112 is provided with a guide surface 1121 away from one end of the second connecting end 12. Along the direction of the body 111 towards the second connecting end 12, the distance between the first guide inclined surface and the body 111 gradually increases.

[0095] Exemplarily, the guide surface 1121 can be a curved surface, or a flat surface, etc.

[0096] Through the above arrangement, during the connection between the connecting terminal 10 and the circuit board 20, since the distance between the first guide inclined surface and the body 111 gradually increases along the direction of the body 111 towards the second connecting end 12, when the guide surface 1121 is in contact with the edge of the through hole 21 away from the second connecting end 12, the guide surface 1121 can guide the body 111, so as to position and install the body 111, thereby ensuring the accuracy of the installation position of the body 111.

[0097] On this basis, in some embodiments, as shown in Figure 3 , Figure 5 the edge of the guide surface 1121 away from the second connecting end 12 is in contact with the body 111.

[0098] Through the above arrangement, since the edge of the guide surface 1121 away from the second connecting end 12 is in contact with the body 111, during the connection between the connecting terminal 10 and the circuit board 20, the support portion 112 will not be in contact with the side surface of the circuit board 20 towards the second connecting end 12, i.e. during the connection between the connecting terminal 10 and the circuit board 20, the support portion 112 will not block the movement of the connecting terminal 10, thereby ensuring the normal connection between the connecting terminal 10 and the circuit board 20.

[0099] In some examples, the support portion 112 comprises a support rib, which is integrally formed with the body 111.

[0100] It can be understood that the material of the support rib can also be copper, iron, aluminum, etc.

[0101] ​It should be noted that, since the material of the connecting terminal 10 is small (for example, the maximum dimension of the body 111 along the first direction is 1 mm, and the maximum dimension of the connecting rib is 0.5 mm), even if the supporting rib is made of metal material, the supporting rib and the body 111 can be inserted into the through hole 21 during the connection of the connecting terminal 10 and the circuit board 20, and the connection of the connecting terminal 10 and the circuit board 20 will not be affected.

[0102] In some other examples, the supporting rib can also be made of elastic material. After the body 111 is processed, the supporting rib is connected to the body 111 by adhesion or clamping, etc.

[0103] In some embodiments, as shown in Figure 3 , Figure 5 The first connecting end 11 further includes a guide portion 113 connected to the side of the body 111 away from the second connecting end 12. The cross-sectional area of the guide portion 113 perpendicular to the direction of the body 111 towards the second connecting end 12 gradually increases along the direction of the body 111 towards the second connecting end 12.

[0104] Exemplarily, the shape of the guide portion 113 can be a cone, a circular truncated cone, a pyramid, a truncated pyramid, etc.

[0105] Through the above arrangement, during the connection of the connecting terminal 10 and the circuit board 20, the radial dimension of the cross-sectional area of the guide portion 113 perpendicular to the direction of the body 111 towards the second connecting end 12 gradually increases along the direction of the body 111 towards the second connecting end 12, so that when the guide portion 113 contacts the edge of the through hole 21 close to the second connecting end 12, the guide portion 113 can guide the body 111, thereby enabling the installation and positioning of the body 111, to further ensure the accuracy of the installation position of the body 111.

[0106] On this basis, in some embodiments, as shown in Figure 3 , Figure 5 The edge of the guide portion 113 close to the body 111 contacts the edge of the body 111 away from the second connecting end 12.

[0107] Through the above arrangement, during the process that the guide portion 113 contacts the edge of the through hole 21 close to the second connecting end 12, the edge of the through hole 21 close to the second connecting end 12 can slide along the outer surface of the guide portion 113 relative to the guide portion 113 until sliding to the edge of the guide portion 113 close to the second connecting end 12.

[0108] In this way, since the guide portion 113 is in contact with the end edge of the body 111 away from the second connecting terminal 12, the body 111 can continue to move to extend into the through hole 21, and the body 111 does not block the movement of the connecting terminal 10 in the process of connecting the connecting terminal 10 and the circuit board 20, so that the normal connection of the connecting terminal 10 and the circuit board 20 can be ensured.

[0109] In some examples, the circuit board 20 comprises a mounting sleeve, the support portion 112 and the body 111 are both arranged in the mounting sleeve and are in contact with the mounting sleeve. The support portion 112 is supported between the mounting sleeve and the body 111.

[0110] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any change or replacement within the technical scope disclosed in the present application should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
