Description

  The present invention relates to a riser card when an add-on card is mounted on a motherboard of a communication device or a personal computer, for example.

  Electronic circuit mounting boards used in communication equipment and personal computers are intended to realize the desired configuration with a motherboard on which main components such as a common circuit and central processing unit are mounted even if the final targeted configuration is different. The add-on card is selected according to the purpose and added to the motherboard, and the add-on card is mounted vertically on the motherboard so that the add-on card is installed on the motherboard so that the add-on card is installed. If the height dimension in the vertical direction of the add-on card motherboard mounted on the motherboard is equal to or greater than the same dimension of the chassis in the chassis where these boards are mounted An add-on card cannot be mounted perpendicular to the motherboard, Mounting method add-on card is mounted is employed in a motherboard with a riser card is redirecting tool for plugging in parallel form Te. The riser card is also used in office and home computers, but is prominently required when it is necessary to configure servers, industrial and industrial high-performance personal computers with limited dimensions.

  The riser card is a structure in which one side of a substantially rectangular printed board and one or more plugs are mounted on the same board surface or a plurality of the plugs, and the plugs mounted on one side of the board are connected to the motherboard. The add-on card is inserted into the riser card vertically into one or more of the plugs inserted into the add-on card mounting plug.

  The advancement and development of communication equipment and computer technology is remarkable, and add-on cards that meet new demands appear every day, and functions that are not included in the motherboard are required to be able to be freely added to the motherboard.

  At the same time, technological advances have brought new connection technologies one after another to realize higher performance and convenience in the connection method between the motherboard and the add-on card. A plug is required. In equipment where the mounting dimensions in the height direction of the add-on card mounted on the motherboard in the housing are limited, a different riser card is required each time a request for mounting the add-on card to the motherboard with a new plug shape appears. Riser cards equipped with multiple add-on card attachment plugs require many types of combinations, so new combinations of riser cards, including existing plug types, increase in a factorial manner. Development takes a lot of time and money.

Furthermore,
When the conventional riser card is realized by integrating different types of plugs on the board, the riser card must be developed as a separate one even if the positions of the plugs are interchanged. If there are restrictions on the riser card or the riser card of the desired configuration does not exist, it will hinder the realization of the main unit itself such as a device or personal computer with the desired configuration. There is inconvenience that the main unit must be configured by using an add-on card of a different plug type from the essential requirement while mounting restrictions, or mounting the add-on card at a different mounting position from the essential requirement. There was also a need to give up the realization of equipment with the desired housing dimensions.

Furthermore,
In order to use a printed circuit board method suitable for mass production, the riser card is often required to be manufactured in a quantity suitable for the method. For this reason, the combination types of plugs may become obsolete due to changes in market requirements before the riser card inventory is used up, and conventional riser cards cannot be diverted to other combination types. In addition, there was a problem that a large amount of riser cards would be discarded. These inconveniences are a major problem to be solved especially in industrial computers that want to realize the main unit with a configuration suitable for the purpose in a small variety of products.

  In view of the above circumstances, the present invention

  (1) By using a riser card as an element for each add-on card attachment plug and configuring it as a set, there is no need to develop a new riser card each time the combined plug configuration changes. Different combination types can be configured,

At the same time,
(2) Since the riser card is configured as a set of elements that are made into common parts, the types of components of the riser card can be reduced.

Furthermore,
(3) There is no need to dispose even if the shape of some of the plugs in the motherboard or riser card or the combination of riser card plugs changes.

  (4) By devising a mechanism that is compatible with conventional riser cards and can be used without changing the motherboard, add-on card, or housing side, it is possible to quickly and economically use various configurations of riser cards. The purpose is to provide.

To achieve the above object, the riser card of the present invention is mounted by converting the insertion direction of an add-on card for expanding the function into the motherboard by 90 degrees with respect to the insertion direction of the plug for mounting the add-on card on the motherboard. In the riser card that does not need to be prepared separately for each combination type of plug-on for the added add-on card

In FIG. 1, the respective contacts of the respective plugs are connected to each other in a one-to-one relationship within the substrate, and a pair of connecting portions rising from the both ends in the longitudinal direction of the printed circuit board at an angle of 90 degrees are integrally disposed. In the printed circuit board having a substantially U-shaped basic element portion having an opening in the upward direction when mounted and (2) one plug-on plug for add-on card and one plug for flat cable, each contact is A base board that is connected to each other in the printed circuit board in a one-to-one relationship and has a pair of connecting parts integrally arranged at both ends in the longitudinal direction of the printed circuit board, and a plug that is inserted into the add-on card mounting plug of the motherboard. One end plug and one flat cable plug are connected to each other, and the insertion board portion arranged on one board is connected to the board. An additional element portion of the assembly connected by one flat cable attached to both ends of the plug,
(3) A pair of joint portions is provided for each additional element portion used together with the screw nut in order to arrange the substrate surfaces of the connecting portions of the basic child portion and the additional element portion on the same plane,
(4) The basic element portion and the additional element portion configured as independent elements for each shape of the plug-on for the add-on card mounting plug are used together with the above screw nuts even if they are replaced with ones having different plug-on plug mounting shapes. The riser card can be constructed without any trouble by the joint portion.

Here, the basic element portion is
(5) The flat cable plug may not be mounted in some embodiments,

(6) The plug-on for mounting the add-on card may not be mounted in some embodiments,

(7) The board end plug portion for insertion into the motherboard may not be provided in some embodiments.

The additional element section is
(8) When fixed to the basic element part with a screw nut and a joint part, the dimension may be such that a gap through which the flat cable can pass is formed above and below the additional element part.

(9) One end is connected to the flat cable plug of the plug board part, and the other end of the flat cable having the plug for the board attached to both ends thereof is connected to the flat cable plug of the basic element part. Good.

Still further, the additional element portion includes:
(10) One end is connected to the flat cable plug of the plug board part, and the plug for the board is attached to both ends, and the flat cable is attached by adding the plug for the board to the middle. The plug for substrate may be coupled to the flat cable plug of the plug substrate portion of the other additional element section, and the other end may be coupled to the flat cable plug of the basic element section.

Still further, the additional element portion includes:
(11) One end is connected to the flat cable plug of the plug board part, and the plug for the board is attached to the both ends. The plug for substrate may be coupled to the flat cable plug of the plug substrate portion of another additional element portion, and the other end may be inserted and coupled to the flat cable plug of the substrate portion.

Furthermore, the basic element portion is
(12) A screw for fixing a riser card mounting bridge having a basic element part fixed to the housing with a spacer or a column in addition to a hole for fixing the additional element part to the connecting part with a screw nut and a joint part. A hole may be provided.

  In the riser card of the present invention, independent components having add-on card plugs of shapes required for the basic element part and the additional element part can be prepared as a common member, and the shapes of the add-on card attachment plugs can be prepared with each other. May be replaced with different ones, and the joint part can be a common member that can be used even when one element part is connected and coupled to each other, so the types of members can be reduced and these members can be combined. Many kinds of riser cards can be realized in various combinations. For example, when two types of sockets A and B are required and a riser card into which three add-on cards can be inserted is configured, a combination of riser cards that may be required The total number of types is (insert number of sockets = 2) in which three add-on cards are arranged in the order of AAA, BBB, AAB, ABA, BAA, BBA, BAB, ABB in the order of the upper, middle and lower stages, respectively. The number of add-on cards that can be inserted = 3) Eight types of powers are conceivable. In the case of a conventional type riser card, it was necessary to prepare these eight types of riser cards separately. However, in the riser card according to the present invention, two types A and B are used as basic element units, and additional element units are used. 2 types for A and B, 1 type for joint part, that is, 5 types in total (number of types for basic element part = 2), (number of types for additional element part = 3) and (number of types of joint part = 1) By preparing the portion, riser cards equivalent to eight types of conventional riser cards can be realized freely.

Further here,
Assuming a case where C increases as the number of types of required plugs and the two types become three types, a greater effect is produced. In the conventional riser card, 19 types of riser cards of CCC, AAC, ACA, CAA, ACC, CCA, CAC, BBC, BCB, CBB, CBB, BBC, BCB, ABC, BCA, CAB, CBA, BAC, ACB are newly added. The total of 27 types of (socket type number = 3) (number of add-on cards that can be inserted = 3) is a riser card of individual combination types. In the riser card, the existing basic element part, the additional element part, and the joint part can be used as they are, and each of the basic element part and the additional element part has one type for C, two types of element parts in total. Riser cards equivalent to a total of 27 combinations of conventional riser cards can be realized simply by preparing them. In this case, the existing joint can be shared.

  After that, even if the number of sockets increases in the same manner, each type of combination of all plug shapes can be obtained by newly preparing one type each of the basic element part and the additional element part, that is, a total of two kinds of element parts. A riser card can be realized. Each element part can be used as a common component for riser cards with various plug-shaped combinations, and new development costs can be greatly reduced compared to conventional riser cards. Even if required, it can be realized economically, and at the same time, the stockability is greatly improved, so it is very easy to respond quickly to any combination type request.

In addition, the riser card of the present invention can be arranged on the same surface having no step by using a joint part for connecting the basic element part and the additional element part, and an add-on mounted on each element part. Since the card mounting plug can secure a mutual positional relationship equivalent to that mounted on a single substrate, it can be used in place of a conventional riser card without any modification to the motherboard, add-on card or casing.

Furthermore,
Even if an add-on card to be inserted into the riser card needs to be inserted into the back side with respect to the riser card, it can be added as a new type of member, and it is mounted on the back in combination with each of the above element parts A riser card for use or double-sided mounting can also be realized relatively easily.

Furthermore,
In reality, there are many more plug shapes than the two types and three-week type of plug shapes. Therefore, according to the present invention, there are many types of riser cards that can be freely combined with members that are made into a common part with fewer types of members. By becoming feasible, it has become possible to easily combine many add-on card combinations that have been abandoned in the past due to the need for new development of riser cards, which are difficult to realize in terms of cost and time, and are small in size. Optimal communication devices and personal computers can be easily realized, and it has a great effect on realization of industrial computers used in manufacturing apparatuses and inspection apparatuses that require high reliability and performance in a small variety and a variety of products, and a short delivery time.

Furthermore,
The flat cable connection plugs can be mounted on either the back or front of each printed circuit board, and can be manufactured from a small amount by specifying the flat cable length or the plug to be combined. By being combined, it is possible to economically add a combination type riser card suitable for the configuration of the main unit more freely without increasing the types of printed circuit boards.

Furthermore,
If the mounting position of the basic element part of the riser card in the housing is limited, if there is no basic element part that matches the plug-on part for mounting the add-on card on the motherboard, By using the omitted basic element part, the additional element part can be used. In this case, the add-on card mounting plug of the basic element section cannot be connected to the add-on card mounting plug of the basic element section of the motherboard with an electrical signal, but can be connected to the plug of another position with the connected flat cable. . In addition, when the add-on card mounting plug is not mounted on the basic part, it can be shared by any shape of the add-on card mounting plug on the motherboard.

FIG. 12 is a circuit board end plug (FIG. 12) that is inserted into a plug for mounting an add-on card on the motherboard into the basic element 23 ′. 4 shows a state in which a riser card without (corresponding to 23b of 4) is mounted on the riser card mounting bridge. FIG. 13 shows a state in which the riser card mounting bridge on which the basic element portion 23 'from which the board end plug is omitted is fixed to the housing.

  For example, if a plug with a shape that is rarely used is an add-on card mounting plug on the motherboard on the main unit corresponding to the fixed position of the riser card, economic resistance arises in the development of the corresponding basic element part, When it is not necessary to mount an add-on card in the lowermost stage (a contact element generally called a gold finger is lined up), a simple basic element portion 23 ′ in which a board end plug portion is omitted can be used. The simple basic element portion 23 'does not require any plug mounting, and as a result, it may be composed of a printed circuit board material without board wiring, or the board end plug portion of the basic element section used in other embodiments. It is also possible to use a material in the shape of a basic element part without a substrate end plug using an iron plate as a material.

  The simple basic element portion 23 ′ is not inserted into the add-on card mounting plug of the motherboard on the main unit because there is no board end plug portion. For this reason, the riser card fixing bridge portion is fixed to the main body housing, and the simple basic element portion 23 ′ is fixed to the bridge portion by the columns 62 a, 62 b, 62 c, 62 d.

  The present invention relates to a riser card when an add-on card is mounted on a motherboard of a communication device or a personal computer, for example.

  Electronic circuit mounting boards used in communication equipment and personal computers are intended to realize the desired configuration with a motherboard on which main components such as a common circuit and central processing unit are mounted even if the final targeted configuration is different. The add-on card is selected according to the purpose and added to the motherboard, and the add-on card is mounted vertically on the motherboard so that the add-on card is installed on the motherboard so that the add-on card is installed. If the height dimension in the vertical direction of the add-on card motherboard mounted on the motherboard is equal to or greater than the same dimension of the chassis in the chassis where these boards are mounted An add-on card cannot be mounted perpendicular to the motherboard, Mounting method add-on card is mounted is employed in a motherboard with a riser card is redirecting tool for plugging in parallel form Te. The riser card is also used in office and home computers, but is prominently required when it is necessary to configure servers, industrial and industrial high-performance personal computers with limited dimensions.

  The riser card is a structure in which one side of a substantially rectangular printed board and one or more plugs are mounted on the same board surface or a plurality of the plugs, and the plugs mounted on one side of the board are connected to the motherboard. The add-on card is inserted into the riser card vertically into one or more of the plugs inserted into the add-on card mounting plug. The plugs provided on one side of the substrate and the plugs provided on the substrate surface are provided to be integrated with the substrate so as to face each other at right angles, and each of the plurality of contacts included in both plug portions is Connected one-to-one.

  Due to recent advances in circuit technology, new connection specifications between the motherboard and add-on cards have been proposed one after another, and a new plug-on shape for mounting an add-on card is used for each method, and at the same time a riser that mounts multiple different plugs Cards require different riser cards for different combinations of plug shapes, and many riser cards must be prepared for each combination type in order to meet a variety of add-on card mounting requirements. There is an economic problem and a development time problem for preparing a wide variety of products. In addition, the progress of the motherboard is fast, and the combination of the plug-on plugs mounted on the motherboard often changes at the same time, resulting in the problem of having to prepare a riser card that matches the motherboard change. Yes.

Patent Publication 2001-15942

  The advancement and development of communication equipment and computer technology is remarkable, and add-on cards that meet new demands appear every day, and functions that are not included in the motherboard are required to be able to be freely added to the motherboard.

  At the same time, technological advances have brought new connection technologies one after another to realize higher performance and convenience in the connection method between the motherboard and the add-on card. A plug is required. In equipment where the mounting dimensions in the height direction of the add-on card mounted on the motherboard in the housing are limited, a different riser card is required each time a request for mounting the add-on card to the motherboard with a new plug shape appears. Since many types of combinations are required for riser cards equipped with multiple add-on card attachment plugs, the number of new combinations of riser cards including existing connector types will increase exponentially. Development takes a lot of time and money.

Furthermore,
When the conventional riser card is realized by integrating different types of plugs on the board, the riser card must be developed as a separate one even if the positions of the plugs are interchanged. If there are restrictions on the riser card or the riser card of the desired configuration does not exist, it will hinder the realization of the main unit itself such as a device or personal computer with the desired configuration. There is inconvenience that the main unit must be configured by using an add-on card of a different plug type from the essential requirement while mounting restrictions, or mounting the add-on card at a different mounting position from the essential requirement. There was also a need to give up the realization of equipment with the desired housing dimensions.

Furthermore,
In order to use a printed circuit board method suitable for mass production, the riser card is often required to be manufactured in a quantity suitable for the method. For this reason, the combination types of plugs may become obsolete due to changes in market requirements before the riser card inventory is used up, and conventional riser cards cannot be diverted to other combination types. In addition, there was a problem that a large amount of riser cards would be discarded. These inconveniences are a major problem to be solved especially in industrial computers that want to realize the main unit with a configuration suitable for the purpose in a small variety of products.

  In view of the above circumstances, the present invention

  (1) A riser card is made into an element for each add-on card attachment plug, and it is configured as a set so that even if the combined plug configuration changes, there is no need to develop a new riser card each time and it can be freely varied Different combination types can be configured,

At the same time,
(2) Since the riser card is configured as a set of elements that are made into common parts, the types of components of the riser card can be reduced.

Furthermore,
(3) There is no need to dispose even if the shape of some of the plugs in the motherboard or riser card or the combination of riser card plugs changes.

  (4) By devising a mechanism that is compatible with conventional riser cards and can be used without changing the motherboard, add-on card, or housing side, it is possible to quickly and economically use various configurations of riser cards. The purpose is to provide.

In order to achieve the above object, the riser card of the present invention converts the insertion direction of the add-on card for expanding the function into the mother board by 90 degrees with respect to the insertion direction of the plug for mounting the add-on card on the motherboard. In the riser card that does not need to be prepared separately for each combination type of plug-on for mounting add-on card,

In FIG. 1, the respective contacts of the respective plugs are connected to each other in a one-to-one relationship within the substrate, and a pair of connecting portions rising from the both ends in the longitudinal direction of the printed circuit board at an angle of 90 degrees are integrally disposed. Printed with a substantially U-shaped basic element having an opening in the upward direction when mounted on a horizontally arranged motherboard, and (2) one add-on card plug and one flat cable plug Each of the contacts on the board is connected to each other in the printed board in a one-to-one relationship, and a substantially rectangular plug board having a pair of connecting portions integrally disposed at both ends of the printed board in the longitudinal direction. Inserts that are placed on a single board with one contact of each of the plugs of the board end plug and one flat cable plug inserted into the plug for attaching the card. And an additional element portion of the assembly connected together by a single flat cable having a plug for the substrate mounted on both ends,
(3) A pair of joint portions is provided for each additional element portion used together with the screw nut in order to arrange the substrate surfaces of the connecting portions of the basic child portion and the additional element portion on the same plane,
(4) The basic element portion and the additional element portion configured as independent elements for each shape of the plug-on for the add-on card mounting plug are used together with the above screw nuts even if they are replaced with ones having different plug-on plug mounting shapes. The riser card can be constructed without any trouble by the joint portion.

Here, the basic element portion is
(5) The flat cable plug may not be mounted in some embodiments,

(6) The plug-on for mounting the add-on card may not be mounted in some embodiments,

(7) The board end plug portion for insertion into the motherboard may not be provided in some embodiments.

The additional element section is
(8) When the basic element part is fixed with a screw nut and a joint part, the additional element part may be of a size that can form a gap through which a flat cable can pass between adjacent element parts,

(9) One end is connected to the flat cable plug of the plug board part, and the other end of the flat cable having the plug for the board attached to both ends thereof is connected to the flat cable plug of the basic element part. Good.

Still further, the additional element portion includes:
(10) One end is connected to the flat cable plug of the plug board part, and the plug for the board is attached to both ends, and the middle part of the flat cable is attached by adding the plug for the board to the middle. The plug for substrate may be coupled to the flat cable plug of the plug substrate portion of the other additional element section, and the other end may be coupled to the flat cable plug of the basic element section.

Still further, the additional element portion includes:
(11) One end is connected to the flat cable plug of the plug base plate part. The plug for the board is attached to both ends of the flat cable, and the flat cable is attached by adding the counter plug for the middle. The plug for substrate may be coupled to the flat cable plug of the plug substrate portion of another additional element portion, and the other end may be inserted and coupled to the flat cable plug of the substrate portion.

Furthermore, the basic element portion is
(12) A screw for fixing a riser card mounting bridge having a basic element part fixed to the housing with a spacer or a column in addition to a hole for fixing the additional element part to the connecting part with a screw nut and a joint part. A hole may be provided.

  In the riser card according to the present invention, a basic element portion having an add-on card plug having a shape required for each of the basic element portion and the additional element portion and a component by the additional element portion are prepared as common members of independent riser cards. Can be replaced with ones with different shapes of plugs for mounting add-on cards, and the joint part can be a common member that can be used even when one of the element parts is connected and joined together. Many types of riser cards can be realized in various combinations by combining these members. For example, when two types of sockets A and B are required and a riser card into which three add-on cards can be inserted is configured, a combination of riser cards that may be required The total number of types is such that three add-on cards are arranged in the order of AAA, BBB, AAB, ABA, BAA, BBA, BAB, ABB in the order of the upper middle stage, lower (socket type number = 2). Eight kinds of power values with (number of add-on cards that can be inserted = 3) as exponents are conceivable. In the case of a conventional type riser card, it was necessary to prepare these eight types of riser cards separately. However, in the riser card according to the present invention, two types A and B are used as basic element units, and additional element units are used. 2 types for A and B, 1 type for joint part, that is, 5 types in total (number of types for basic element part = 2), (number of types for additional element part = 3) and (number of types of joint part = 1) By preparing the portion, riser cards equivalent to eight types of conventional riser cards can be realized freely.

Further here,
Assuming a case where C increases as the number of types of required plugs and the two types become three types, a greater effect is produced. In the conventional riser card, 19 types of riser cards of CCC, AAC, ACA, CAA, ACC, CCA, CAC, BBC, BCB, CBB, CBB, BBC, BCB, ABC, BCA, CAB, CBA, BAC, ACB are newly added. Are added to the above eight types, and (socket type number = 3) is low (number of add-on cards that can be inserted = 3), and a total of 27 types of exponent values are used as individual combination types. In the riser card according to the present invention, the existing basic element part, the additional element part, and the joint part can be used as they are, and a new C element is added to each of the basic element part and the additional element part. A riser card equivalent to a total of 27 types of combinations of conventional riser cards can be realized only by preparing a total of two types of element portions. In this case, the existing joint prepared before C increases can be shared.

  After that, even if the number of sockets increases in the same manner, each type of combination of all plug shapes can be obtained by newly preparing one type each of the basic element part and the additional element part, that is, a total of two kinds of element parts. A riser card can be realized. Each element part can be used as a common component for riser cards with various plug-shaped combinations, and new development costs can be greatly reduced compared to conventional riser cards. Even if required, it can be realized economically, and at the same time, the stockability is greatly improved, so it is very easy to respond quickly to any combination type request.

In addition, the riser card of the present invention can be arranged on the same surface having no step by using a joint part for connecting the basic element part and the additional element part, and an add-on mounted on each element part. Since the card mounting plug can secure a mutual positional relationship equivalent to that mounted on a single substrate, it can be used in place of a conventional riser card without any modification to the motherboard, add-on card or casing.

Furthermore,
Even if an add-on card to be inserted into the riser card needs to be inserted into the back side with respect to the riser card, it can be added as a new type of member, and it is mounted on the back in combination with each of the above element parts A riser card for use or double-sided mounting can also be realized relatively easily.

Furthermore,
In reality, there are many more plug shapes than the two types and three-week type of plug shapes. Therefore, according to the present invention, there are many types of riser cards that can be freely combined with members that are made into a common part with fewer types of members. By becoming feasible, it has become possible to easily combine many add-on card combinations that have been abandoned in the past due to the need for new development of riser cards, which are difficult to realize in terms of cost and time, and are small in size. Optimization and realization of industrial computers used in manufacturing equipment and inspection equipment that are easy to realize optimal communication equipment and personal computers, require high reliability and performance in a small variety, and require an optimal add-on card configuration In addition, it has a great effect on shortening the delivery time.

Furthermore,
The flat cable connection plugs can be mounted on either the back or front of each printed circuit board, and can be manufactured from a small amount by specifying the flat cable length or the plug to be combined. By being combined, it is possible to economically add a combination type riser card suitable for the configuration of the main unit more freely without increasing the types of printed circuit boards.

Furthermore,
When the mounting position of the basic element part of the riser card in the main unit housing is limited, if there is no basic element part that matches the plug-in for mounting the add-on card at that position on the motherboard, the plug-on for adding the add-on card By using the basic element part in which the part and the substrate end plug part are omitted, the desired additional element part can be used without developing a new basic element part each time. In this case, the add-on card mounting plug of the basic element section cannot be connected to the add-on card mounting plug of the basic element section of the motherboard with an electrical signal, but can be connected to the plug of another position with the connected flat cable. . Further, when the add-on card mounting plug is not mounted on the basic element section, the basic element section can be shared by any shape of the add-on card mounting plug on the motherboard.
