Description

  The present invention relates to a technique for electrically and mechanically connecting objects such as a plurality of circuit boards.

  FIG. 11 is a diagram illustrating an example of a case where a plurality of circuit boards are stacked (stacked) in the thickness direction of the circuit boards. In this example, the plurality of circuit boards 61 and 62 are laminated in a state where at least a part thereof overlaps. A connector (stacking connector) 65 is provided in an area of the circuit boards 61 and 62 that overlap each other. The connector 65 mechanically combines the circuit boards 61 and 62 and electrically connects the electric circuits 63 and 64 formed on the circuit boards 61 and 62, respectively.

  FIG. 12 is a model diagram illustrating a configuration example of the connector 65 (see, for example, Patent Document 1). The connector 65 has a male part 66 and a female part 67.

  The male part 66 has a housing 70, a connection pin 71, and a mounting pin 72 shown in the side view of FIG. The mounting pin 72 protrudes from the housing 70. The mounting pin 72 is made of a conductor material. A through-hole (or via hole) corresponding to the mounting pin 72 is formed in the circuit board 61 to be mounted to which the male part 66 is to be mounted. The mounting pin 72 is configured to be fitted into the through hole (via hole) by being press-fitted (press fit) into the through hole (via hole). For this reason, the attachment pin 72 may be called a press-fit pin or a press-fit terminal.

  The male component 66 can be fixed to the circuit board 61 by press-fitting the mounting pins 72 into the through holes of the circuit board 61. A conductor film that is electrically connected to the electric circuit 63 of the circuit board 61 is formed on the inner wall surface of the through hole of the circuit board 61 into which the mounting pin 72 is press-fitted. From this, the mounting pin 72 is electrically connected to the electric circuit 63 of the circuit board 61 by press-fitting the mounting pin 72 into the through hole of the circuit board 61 as described above.

  The connection pins 71 are provided in one-to-one correspondence with the mounting pins 72. The connection pin 71 is made of a conductive material and is electrically connected to the corresponding mounting pin 72 by connection means provided inside the housing 70. In the configuration shown in Patent Document 2, the members corresponding to the connection pins 71, the connection means inside the housing 70, and the mounting pins 72 are integrated.

  As shown in FIGS. 12 and 13, the female part 67 has a housing 74 and a mounting pin 76. The housing 74 is formed with a fitting hole 75 corresponding to the connection pin 71 of the male part 66 on a one-to-one basis. A conductor member is provided inside the fitting hole 75. The fitting hole 75 has a size that allows the connection pin 71 to be inserted, and can maintain a state in which the inserted connection pin 71 is in contact with the internal conductor member. For this reason, by inserting the connection pin 71 of the male part 66 into the fitting hole 75 of the female part 67, the connection pin 71 is electrically connected to the conductor member in the fitting hole 75.

  The mounting pin 76 protrudes from the housing 74. The mounting pins 76 correspond one-to-one with the fitting holes 75. The mounting pin 76 is made of a conductor material. The mounting pin 76 is electrically connected to a conductor member inside the corresponding fitting hole 75 by a connecting member provided inside the housing 74.

  Similar to the mounting pin 72, the mounting pin 76 is a pin called a press-fit pin or a press-fit terminal. That is, the circuit board 62 to be attached to which the female part 67 is attached has through holes corresponding to the attachment pins 76 on a one-to-one basis. The female part 67 can be fixed to the circuit board 62 by press-fitting the mounting pins 76 into the through holes.

  A conductive film that is electrically connected to the electric circuit 64 of the circuit board 62 is formed on the inner wall surface of the through hole of the circuit board 62 into which the mounting pin 76 is press-fitted. For this reason, the mounting pin 76 is electrically connected to the electric circuit 64 of the circuit board 62 by press-fitting the mounting pin 76 into the through hole. That is, the conductor member inside the fitting hole 75 is electrically connected to the electric circuit 64 of the circuit board 62 via the mounting pin 76.

  The male part 66 and the female part 67 are configured as described above. Therefore, the circuit boards 61 and 62 are combined with each other by fitting the connection pins 71 of the male part 66 fixed to the circuit board 61 and the fitting holes 75 of the female part 67 fixed to the circuit board 62. The electric circuits 63 and 64 can be electrically connected. In other words, the circuit boards 61 and 62 can be stacked.

  By the way, when the electric circuit 63 of the circuit board 61 operates normally, but the electric circuit 64 of the circuit board 62 has a defect, the circuit board on one side of the circuit boards 61 and 62 has a problem. There is. In such a case, a repair technique may be used in which a defective circuit board is removed from a normal circuit board and another normal circuit board is attached to the normal circuit board in place of the defective circuit board. is there. In consideration of this, the connection pin 71 of the male part 66 and the fitting hole 75 of the female part 67 are designed to be freely fitted and unfitted. In this design, it is considered that electrical connection between the connection pin 71 and the conductor member inside the fitting hole 75 (more specifically, connection that can transmit a high-frequency signal satisfactorily) is realized. The connection strength between the connection pin 71 and the fitting hole 75 is designed.

  Further, when the fitting between the connection pin 71 and the fitting hole 75 is canceled, the male component 66 and the female component 67 have a force in the direction of removing the components 66 and 67 from the circuit boards 61 and 62. Works. This force is a force having a magnitude corresponding to the connection strength between the connection pin 71 and the fitting hole 75 described above. In order to prevent the components 66 and 67 from coming off the circuit boards 61 and 62 even when such a force is applied, the mounting pins 72 and 76 of the male part 66 and the female part 67 and the circuit boards 61 and 62 The connection strength is designed.

  When the housings 70 and 74 in the male part 66 and the female part 67 are designed in consideration of the design matters as described above, in order to support the pins 71, 72 and 76 well, There is a problem that thinning is difficult. This causes a problem that it is difficult to reduce the distance between the circuit boards 61 and 62 that are stacked (stacked) using the male part 66 and the female part 67.

  The present invention has been made to solve such problems (problems). That is, the main object of the present invention is to provide a technique that facilitates narrowing the interval (gap) between circuit boards to be connected.

In order to achieve the above object, the connecting component of the present invention comprises:

  Embodiments according to the present invention will be described below with reference to the drawings.

(First embodiment)
FIG. 1 is a diagram schematically showing the connection component of the first embodiment according to the present invention. The connection component 1 according to the first embodiment includes a first conductor pin 2, a second conductor pin 3, and a support member 4. The first conductor pin 2 is a pin that is connected to the object 6 by being press-fitted into the object 6 to be connected. The second conductor pin 3 is a pin that is connected to the object 7 by press-fitting into a different connection target object 7 different from the connection target object 6.

  The support member 4 is a member that supports the first conductor pin 2 and the second conductor pin 3. The support member 4 includes a first surface 9 from which the first conductor pin 2 protrudes, a second surface 10 from which the second conductor pin 3 protrudes, and a connection member 11. The connection member 11 is a member that electrically connects the first conductor pin 2 and the second conductor pin 3.

  The connection component 1 according to the first embodiment having the above-described configuration is configured such that the first conductor pin 2 and the second conductor pin 3 are connected to the corresponding connection target objects 6 and 7 by press-fitting, so that the object 6 , 7 are electrically and mechanically connected.

  The connecting component 1 according to the first embodiment is a component having a simple configuration in which the first conductor pin 2 and the second conductor pin 3 protrude from the support member 4. As a result, the support member 4 of the connection component 1 according to the first embodiment has, for example, the total thickness of the housings 70 and 74 of the connector 65 having the male component 66 and the female component 67 as shown in FIG. Can also be thinned. For this reason, the connection component 1 can be made smaller (thinner) than the connector 65.

  As a result, when the objects 6 and 7 that are at least partially overlapped are connected using the connection component 1 of the first embodiment in the overlapping part, the distance between the objects 6 and 7 is further increased. It becomes easy to narrow. That is, when connecting (stacking) in the state where the objects 6 and 7 to be connected are stacked, it is easy to narrow the interval between the objects 6 and 7. Thereby, the connection component 1 can contribute to size reduction of an apparatus provided with the connected objects 6 and 7. Further, in the device including the objects 6 and 7, the connection component 1 creates a space that can reduce the interval between the objects 6 and 7 to be connected without increasing the size of the device. As a result, it is possible to use bulky parts depending on the space, and to develop such as adding parts. Therefore, the connecting part 1 contributes to the enhancement of the function of the device including the objects 6 and 7. It is also possible to do.

  FIG. 2 is a diagram illustrating an example of a circuit board having the connection component 1. The circuit board 15 is configured to be electrically and mechanically connected to another circuit board 16 using the connection component 1.

  The circuit board 15 uses the connection component 1 as compared with the case where the circuit board 15 is connected to the circuit board 16 using a connector 65 having a male part 66 and a female part 67 as shown in FIG. Thus, the distance from the circuit board 16 can be reduced. Thereby, the circuit board 15 can contribute to size reduction of the apparatus provided with the circuit boards 15 and 16. In addition, the circuit board 15 can contribute to the enhancement of the function of the apparatus without increasing the size of the apparatus including the circuit boards 15 and 16.

(Second Embodiment)
The second embodiment according to the present invention will be described below.

  FIG. 3 is a side view schematically showing the connection component of the second embodiment according to the present invention. The connection component 20 includes a first conductor pin 21, a second conductor pin 22, and a support member 23.

  The support member 23 is a solid body made of an insulating material such as resin. The support member 23 has a shape (for example, a rectangular parallelepiped shape) having a flat surface 24 that is a first surface and a flat surface 25 that is a second surface facing each other. FIG. 4 is a perspective view showing the support member 23 together with the conductor pins 21 (22). As shown in FIGS. 3 and 4, in the second embodiment, a plurality of openings 28 are formed in the planes 24 and 25 of the support member 23. In the example of FIG. 4, the openings 28 are arranged in a matrix.

  Inside the support member 23, a through hole 30 is formed that connects the opening portion 28 of the flat surface 24 and the opening portion 28 of the flat surface 25 corresponding to the opening portion 28 on a one-to-one basis. A conductor film 31 is formed on the inner wall surface of the through hole 30. That is, the through hole 30 has a form of a through hole.

  In the second embodiment, the first conductor pin 21 is fixed by being press-fitted into the through hole 30 from the opening portion 28 of the plane (first surface) 24. Further, the second conductor pin 22 is fixed to the through hole 30 by press-fitting from the opening 28 of the flat surface (second surface) 25. The first conductor pin 21 and the second conductor pin 22 thus fixed to the through hole 30 are electrically connected via the conductor film 31 by abutting against the common conductor film 31. That is, the conductor film 31 has a function as a connection member that electrically connects the first conductor pin 21 and the second conductor pin 22.

  In the second embodiment, the first conductor pin 21 and the second conductor pin 22 have the same shape and the same size. That is, the first conductor pin 21 and the second conductor pin 22 are the same component. Therefore, hereinafter, the first conductor pin 21 and the second conductor pin 22 may be collectively referred to as conductor pins 21 and 22. As described above, since the first conductor pin 21 and the second conductor pin 22 are the same component, the number of components constituting the connection component 20 can be suppressed.

  The conductor pins 21 and 22 are press-fitted into the through holes 30 of the support member 23 as described above, and at least a part thereof is fixed to the support member 23 in a form protruding from the flat surfaces 24 and 25 of the support member 23. .

  As shown in FIG. 4, the conductor pins 21 and 22 have a fitting portion 33, a protruding portion 34, and an overhang portion 36. The fitting portion 33 is a portion that fits (press-fits) into the through hole 30 of the support member 23. The protruding portion 34 is a portion protruding from the flat surfaces 24 and 25 of the support member 23. In the second embodiment, the fitting portion 33 and the protruding portion 34 have the same shape (press-fit type pin shape).

  That is, the fitting part 33 and the protruding part 34 each have an elastic deformation part 35. A slit 37 is formed in the elastic deformation portion 35 in such a manner as to extend in the press-fitting direction of the conductor pins 21 and 22 (direction in which the conductor pins 21 and 22 are press-fitted into the through holes 30). With this slit 37, the elastic deformation portion 35 can be elastically deformed in the direction in which the slit 37 becomes narrower. The elastically deforming portion 35 has a width that is slightly larger than the diameter of the through hole 30. For this reason, the elastically deforming portion 35 is configured to be elastically deformed in a direction in which the slit 37 is narrowed in a state where the elastic deforming portion 35 is press-fitted into the through hole 30, thereby pressing the inner wall surface of the through hole 30 with an elastic force.

  When the force in the direction of press-fitting into the through hole 30 acts on the conductor pins 21 and 22, the overhanging portion 36 is engaged with the opening edge of the through hole 30, so that the conductor pins 21 and 22 are brought into the through hole 30. It has a stopper function that regulates the length of entry.

  The connection component 20 of the second embodiment is configured as described above. As shown in FIG. 6, the connection component 20 of the second embodiment can electrically and mechanically connect the circuit boards 40 and 41 that are objects to be connected. That is, through holes 43 and 44 for connection are formed in the circuit boards 40 and 41, as shown in the perspective view of FIG. These through holes 43 and 44 are electrically connected to an electric circuit formed in the circuit boards 40 and 41. In the example of FIG. 6, the first conductor pin 21 of the connection component 20 is press-fitted into the through hole 43 of the circuit board 40. Further, the second conductor pin 22 of the connection component 20 is press-fitted into the through hole 44 of the circuit board 41. Thereby, the circuit boards 40 and 41 are electrically and mechanically connected by the connection component 20 in a state where at least a part thereof is overlapped. As described above, the protruding portions 34 of the conductor pins 21 and 22 have the same shape as the fitting portion 33, that is, a press-fit type pin shape, so that they are firmly pressed into the circuit boards 40 and 41. Fixed.

  In the connection component 20 of the second embodiment, the circuit boards 40 and 41 are connected (stacked) by one component having a simple configuration in which the conductor pins 21 and 22 protrude from the support member 23. For this reason, the connection component 20 can narrow the space | interval between circuit boards compared with the case where circuit boards are connected by the connector which has a male type | mold part and a female type | mold part. As a result, as in the first embodiment, the connection component 20 has an effect that, for example, the device including the circuit boards 40 and 41 can be downsized, and the device can be enhanced without increasing its size. Can be obtained.

  Incidentally, FIGS. 7A, 7B, and 7C are plan views of circuit boards, respectively. Assume that a new request for mounting the component 48 is made on the circuit board 50 on which the components 46 and 47 as shown in FIG. 7B are mounted. In this case, when there is no space for mounting the new component 48 in the circuit board 50, for example, the shape of the circuit board 50 is changed to a shape as shown in FIG. It is conceivable to change the design to an expanded shape in order to provide However, if the electrical circuit formed on the circuit board 50 is complicated and the number of circuit boards (laminated boards) 50 is large, the price of the circuit board 50 increases when the circuit board 50 is expanded.

  On the other hand, as shown in FIG. 7A, a circuit board 51 on which a simple circuit on which components 48 are mounted is formed separately from the circuit board 50, and the board 51 is connected to the circuit board 50. By doing so, it is conceivable to incorporate the component 48 into the electric circuit of the circuit board 50. Such a configuration (a multi-stage circuit board 50) can suppress an increase in price as compared with the case where an expanded circuit board 50 as shown in FIG. 7C is used. However, in this case, since the circuit board 51 is laminated on the circuit board 50, the circuit board 50 becomes bulky. For this reason, there exists a possibility that the problem that the circuit board 50 of such a multistage structure cannot be arrange | positioned in the space which should arrange the circuit board 50 may generate | occur | produce.

  In the connection component 20 of the second embodiment, when the circuit board 51 is stacked on the circuit board 50, the distance between the circuit boards 50 and 51 is smaller than when a connector having a male part and a female part is used. Can be narrowed. From this, the connection component 20 can realize the use of the circuit board 50 having a multistage structure as shown in FIG. 7A even when the space for arranging the circuit board 50 is limited. To do. That is, the connection component 20 facilitates a design change that suppresses an increase in price in the electric circuit of the circuit board 50. In other words, the connection component 20 can relax restrictions on the design change of the electric circuit of the circuit board 50.

  Further, the connection component 20 of the second embodiment is configured to connect (fix) the conductor pins 21 and 22 to the object to be connected and the support member 23 by press-fitting. That is, in the connection component 20, since it is not assumed that the fitting state between the conductor pins 21 and 22 and the object to be connected or the support member 23 is eliminated, the connection component 20 includes the conductor pins 21 and 22. Is firmly fixed to the object to be connected and the support member 23. Thereby, the connection component 20 can satisfactorily perform the electrical connection between the conductor pins 21 and 22 and the object to be connected, and the electrical connection between the conductor pins 21 and 22 and the support member 23. That is, the connection component 20 can suppress the deterioration of the noise ratio (SN (Signal-Noise) ratio) in the high-frequency signal in the electrical connection portion of the circuit board by the connection component 20, thereby reducing the quality of the high-frequency signal. Can be prevented.

  Further, in the second embodiment, the conductor pins 21 and 22 are fixed to the support member 23 by press fitting, instead of being integrally molded to the support member 23 by a resin molding technique. On the other hand, for example, if the conductor pins 21 and 22 are integrated (fixed) by the resin molding technique on the support member 23, if the arrangement position of the conductor pins 21 and 22 is changed, the support member 23 Therefore, it is necessary to change the design of the mold for manufacturing the 23. Changing the design of the mold requires a great deal of labor and a large amount of money, so it is not easy to change the design of the arrangement positions of the conductor pins 21 and 22.

  On the other hand, the connection component 20 of the second embodiment has a configuration in which the conductor pins 21 and 22 are fixed to the support member 23 by press fitting as described above. For this reason, if the through hole 30 is provided in the support member 23 at a position where the conductor pins 21 and 22 are supposed to be installed, the conductor pins 21 and 22 can be installed without changing the design of the support member 23. It is easy to change the position and number of installations. For example, the connecting component 20 may be configured to fix the conductor pins 21 and 22 to all of the through holes 30 shown in FIG. 4 without changing the design of the support member 23, or to the left end row of through holes 30. It is possible to easily change the configuration in which the conductor pins 21 and 22 are not fixed.

  Further, in the second embodiment, the conductor pins 21 and 22 have an overhang portion 36. With this configuration, when the conductor pins 21 and 22 are press-fitted into the object to be connected, the length that the conductor pins 21 and 22 enter the through hole 30 of the support member 23 due to the reaction force of the press-fitting can be limited. it can. Thus, the conductor pins 21 and 22 can be prevented from being pushed into the through-hole 30 instead of the object to be connected during the press-fitting. Can be press-fitted reliably. For this reason, the connection component 20 can improve the reliability with respect to the connection with the object of connection object. Further, as described above, since the connection component 20 can more reliably connect the conductor pins 21 and 22 and the object to be connected, there is no need to provide spare conductor pins 21 and 22 for ensuring connection. Can be obtained.

  The support member 23 may have the following configuration. That is, when a high-frequency signal differential signal is passed between objects to be connected, the support member 23 has a configuration for shielding the differential signal. That is, as shown in FIG. 8, the support member 23 is provided with conductor pins 21 and 22 that function as ground corresponding pins to be grounded. The support member 23 is provided with conductor pins 21 and 22 that function as differential signal corresponding pins corresponding to the differential signals. Further, the support member 23 is provided with a shield portion 54 that shields the conductor pins 21 and 22 as the differential signal corresponding pins by being electrically connected to the conductor pins 21 and 22 as the ground corresponding pins. .

(Third embodiment)
The third embodiment according to the present invention will be described below. In the description of the third embodiment, the same reference numerals are given to the same components as the components constituting the connection component 20 of the second embodiment, and the overlapping description of the common portions will be omitted.

  FIG. 9A shows the connection component 56 in the third embodiment. The connection component 56 in the third embodiment has the same configuration as the connection component 20 except that the second conductor pin 22 of the connection component 20 in the second embodiment is omitted.

  In this connection component 56, since the second conductor pin 22 is omitted, one opening portion of both ends of the through hole 30 in the support member 23 is open. As shown in FIG. 9B, the connection component 56 in the third embodiment press-fits one of the conductor pins 21 and 22 of the connection component 20 from the opening where the through hole 30 is opened. Thus, the connection part 20 can be connected. Thereby, the connection component 56 takes the aspect as the one connection component 57 with the connection component 20. FIG.

  As described above, the connection component 56 according to the third embodiment becomes one connection component 57 together with the connection component 20, whereby the following effects can be obtained. That is, as shown in the side view of FIG. 10, the overlapping area of the circuit boards 40 and 41 to be connected (stacked) overlaps with the thickness (height) of the support member 23 of the connection component 20. Assume that a high part 58 is arranged. In such a case, since the distance between the circuit boards 40 and 41 cannot be made smaller than the height of the tall component 58, the circuit boards 40 and 41 cannot be connected by the connecting component 20 alone. In such a case, as shown in FIG. 9B, by connecting the connection component 56 to the connection component 20, it is possible to obtain the connection component 57 that matches the distance between the circuit boards 40 and 41. The connection component 57 enables connection between the circuit boards 40 and 41.

(Other embodiments)
In addition, this invention can take various embodiment, without being limited to the aspect shown to the 1st-3rd embodiment. For example, in the third embodiment, the connection component 57 is configured by connecting the connection component 56 to the connection component 20. On the other hand, for example, when the interval between the circuit boards 40 and 41 is wider than the interval shown in FIG. 9B, for example, another circuit is provided above the connection component 56 shown in FIG. 9B. The connection component 56 may be further connected. Thereby, the connection component comprised by connecting the some connection component 56 to the connection component 20 can respond to the wider space | interval between the circuit boards 40 and 41. FIG. Further, as shown in FIG. 9C, the first conductor pin 21 of the connection component 20 and the connection component 56 are connected, and the second conductor pin 22 of the connection component 20 and another connection component 56 are connected. One connection component 60 may be configured by connection. Furthermore, the connection component may be configured by connecting three or more connection components 56 to the connection component 20.

  Furthermore, the connection component including such connection components 20 and 56 may be configured such that a plurality of types of connection components 56 having different thicknesses of the support member 23 are connected to the connection component 20. That is, a plurality of types of connection components 56 having different thicknesses of the support member 23 are prepared, and the connection components including the connection components 20 and 56 are selected according to the interval between the objects to be connected. It may be configured by connecting 56 to the connection component 20. This connection component can have a more appropriate thickness in the interval between objects to be connected.

  Furthermore, in the second and third embodiments, the conductor pins 21 and 22 are electrically connected by the conductor film 31 of the through hole 30. On the other hand, the connection member that electrically connects the conductor pins 21 and 22 may be a member other than the conductor film 31.
