Description

  The present invention relates to a connector, and more particularly to a connector including a fixed housing, a connection terminal, and a movable housing that is displaceable relative to the fixed housing by the connection terminal.

As an example of a conventional connector, a connection terminal (contact) provided with an elastic portion at an intermediate portion thereof is attached to a fixed housing (housing) and a movable housing (block) so that the movable housing floats with respect to the fixed housing. There is known a connector disposed in (see, for example, Patent Document 1). FIG. 14 is a perspective view of a connector disclosed in Patent Document 1. FIG.
Japanese Patent Laid-Open No. 2003-45525 (pages 2 to 4, FIG. 1)

  As shown in FIG. 14, the connector 1 is a male connector for board-to-board connection, and includes a plurality of connection terminals 2 arranged in two rows and a plurality of contact terminals 2 a for accommodating the connection portions 2 a. The movable housing (block) 3 in which the contact portion accommodating chamber 3a is formed, and the fixed housing (housing) 4 in which the connection portion 2b of the connection terminal 2 is fixed.

  In the connector 1, the connection portion 2b of the connection terminal 2 is electrically connected to a land (not shown) of the conductive pattern of the electric circuit board by soldering or the like, and the fixed housing 4 is connected to the electric circuit board (not shown). Fixed. The connector 1 is fitted with a mating connector (not shown) at the movable housing 3.

  The inner size of the substantially box-shaped fixed housing 4 is larger than the outer size of the movable housing 3, and an annular gap 5 is formed between the movable housing 3 and the fixed housing 4. The movable housing 3 and the fixed housing 4 are connected only by the plurality of connection terminals 2, and the elastic portion 2 c of the connection terminal 2 can be elastically deformed, so that the movable housing 3 is floated to be displaceable with respect to the fixed housing 4. ing.

  Therefore, when the connector 1 is mated with a mating connector (not shown), the movable housing 3 is displaced by elastic deformation of the connection terminal 2 even if an external force acts on the movable housing 3 from a direction other than the normal mating direction. Therefore, the fitting is performed reliably. Therefore, the error in the mounting position of the connector 1 on the electric circuit board (not shown) is substantially absorbed, and the connector 1 and the counterpart connector (not shown) are securely connected.

  By the way, in order to meet the recent demand for connector miniaturization, it is necessary to set the pitch between the connection terminals narrow. However, when the connector 1 is simply miniaturized, the connection terminal 2 is being energized, for example, a mating connector (not connected). When the displacement of the movable housing 3 is excessive particularly in the direction in which the rows of the connection terminals 2 are arranged, the elastic portions 2c of the adjacent connection terminals in each row of the connection terminals 2 come into contact with each other. Then, there is a possibility of electrical short-circuit (ie, short-circuit). Therefore, in order to realize a small connector that requires a narrow pitch between the connection terminals, it is important to take measures to prevent the connection terminals from being short-circuited.

  In addition, since the elastic deformation of the connection terminals 2 in the direction substantially orthogonal to the direction in which the rows of the connection terminals 2 are arranged is restricted by the opposing side wall portions of the fixed housing 4, the amount of displacement of the movable housing 3 in this direction is sufficient. I can't get it. Therefore, there is a possibility that the mating with the counterpart connector (not shown) is not performed smoothly.

  The present invention has been made in view of the above-described circumstances, and an object of the present invention is to provide a connector in which connection terminals do not come into contact with each other when the movable housing is displaced with respect to the fixed housing, and further downsize the connector. Even if it does, it is providing the connector from which the displacement amount with respect to the fixed housing of a movable housing is fully obtained (in other words, regulation of the elastic deformation of the connection terminal by the side wall part of a fixed housing can be reduced).

In order to achieve the object described above, the connector according to the present invention is characterized by the following (1) and (2) .
(1) comprises a stationary housing fixed to the substrate, a plurality of connecting terminals, and a movable housing that is movably supported relative to the stationary housing by the plurality of connection terminals,
The fixed housing has opposing side wall portions;
Each of the connection terminals can come into contact with the connection terminal of the counterpart connector when the leg portion fixed to the side wall portion of the fixed housing is fitted to the counterpart connector in a state where a part protrudes outside the fixed housing. A contact portion fixed inside the movable housing in a state, and an elastic portion formed integrally with the leg portion and the contact portion between the leg portion and the contact portion,
The movable housing is disposed between the opposing side wall portions of the fixed housing, and is movable between the side wall portions by displacement of the elastic portion of the connection terminal;
The side wall portion of the fixed housing communicates the elastic portion accommodating chamber partitioned by a plurality of partition walls for individually accommodating the elastic portions of the plurality of connection terminals, and the elastic portion accommodating chamber to the outside of the fixed housing. Having a through hole,
An elastic displacement toward the outside of the fixed housing is allowed by the through hole with respect to the elastic portion of the connection terminal accommodated in the elastic portion accommodating chamber .
(2) The fixed housing can be fixed to one electric circuit board, the legs of the plurality of connection terminals can be electrically connected to the one electric circuit board, and the movable housing can be connected to the other electric circuit board. It can be fitted with a mating connector that can be fixed to the electric circuit board.

  According to the present invention, the fixed housing includes a side wall portion, and a plurality of partition walls formed in the side wall portion and partitioning the side wall portion so as to form a plurality of elastic portion accommodating chambers in the side wall portion, and the fixed housing Since the elastic portions of the plurality of connection terminals are respectively accommodated in the elastic portion accommodating chamber, the elastic portions of the plurality of connection terminals can be individually separated by the partition walls and arranged in the elastic portion accommodating chamber. Therefore, there is no possibility that the connection terminals come into contact with each other when the movable housing is displaced with respect to the fixed housing, and a measure for preventing the connection terminals from being short-circuited is ensured. Therefore, the connector can be downsized.

Since the side wall portion of the fixed housing has a through hole formed so as to allow elastic displacement from the elastic portion accommodating chamber to the outside of the fixed housing and to allow the elastic portion to move outside the fixed housing. The elastic portion of the terminal does not interfere with the side wall portion of the fixed housing and the elastic deformation is not hindered, and the degree of freedom of the elastic deformation is increased. That is, since the through hole is formed in the side wall portion of the fixed housing so as to penetrate the elastic portion of the connection terminal in the elastic displacement direction, even if the connector is downsized, the displacement amount of the movable housing relative to the fixed housing is sufficient. (In other words, the restriction of elastic deformation of the connection terminal by the side wall portion of the fixed housing can be reduced).

  Further, according to the present invention, the fixed housing can be fixed to one electric circuit board, the leg portions of the plurality of connection terminals can be electrically connected to the one electric circuit board, and the movable housing includes: Since it can be fitted to a mating connector that can be fixed to the other electric circuit board, a connector suitable for board-to-board connection can be provided.

  The present invention has been briefly described above. Furthermore, the details of the present invention will be further clarified by reading through the best mode for carrying out the invention described below with reference to the accompanying drawings.

  As shown in FIGS. 1 to 13, a connector 10 according to an embodiment of the present invention is a board-to-board male connector, and includes a fixed housing 11, a movable housing 12, and a plurality of connection terminals 13. . Each of the plurality of connection terminals 13 is mated with a mating connector 30 which is a female connector for board-to-board connection, and a leg portion 13b fixed to the fixed housing 11 so as to partially protrude out of the fixed housing 11. The contact portion 13a fixed in the movable housing 12 so as to be in contact with and electrically connected to the connection terminal 31 of the connector 30, and the leg portion 13b so as to be provided between the leg portion 13b and the contact portion 13a, and It has the elastic part 13c formed integrally with the contact part 13a. The movable housing 12 is disposed so as to be displaceable with respect to the fixed housing 11 by these connection terminals 13. The fixed housing 11 includes a side wall portion 11a and a plurality of partition walls 11e that are formed in the side wall portion 11a and partition the inside of the side wall portion 11a so as to form a plurality of elastic portion accommodating chambers 11f in the side wall portion 11a. . The elastic portions 13c of the connection terminals 13 are accommodated in the elastic portion accommodating chambers 11f of the fixed housing 11, respectively.

  Further, the side wall portion 11a of the fixed housing 11 communicates from the elastic portion accommodating chamber 11f to the outside of the fixed housing 11 and is an elongated hole formed so as to allow elastic displacement of the elastic portion 13c toward the outside of the fixed housing 11 (that is, , Through-hole) 11d.

  The fixed housing 11 is fixed to one printed circuit board (that is, one electric circuit board) 14. The leg portions 13 b of the plurality of connection terminals 13 are electrically connected to one printed circuit board 14. The mating connector 30 is fixed to the other printed circuit board (that is, the other electric circuit board) 24. The movable housing 12 is fitted with the counterpart connector 30.

  Details of the connector 10 thus configured will be described below.

  The fixed housing 11 is for holding the movable housing 12 inside thereof, and is formed by injection molding a synthetic resin having electrical insulation.

  The fixed housing 11 has a hollow, substantially square frame-shaped main body that includes a side wall 11a, a side wall 11a, a side wall 11b, and a side wall 11b, and is provided with a rectangular through hole 11c at the center. A long hole 11d is formed in the upper part of both side wall portions 11a in the longitudinal direction, and a plurality of partition walls 11e are vertically extended from the side wall portions 11a at predetermined intervals along the side wall portion 11a. As a result, a large number (for example, 30 at 0.8 mm intervals) of the elastic portion accommodating chambers 11f are formed between the adjacent partition walls 11e so as to be separated from each other at a predetermined interval. A part (upper part in FIG. 1) of each elastic part accommodating chamber 11 f communicates with the long hole 11 d and opens to the outside of the fixed housing 11. In addition, a large number of slits 11k are provided in the lower portion of the side wall portion 11a so as to correspond to the elastic portion accommodating chamber 11f. And the one end part of the connection terminal 13 is inserted and accommodated in the elastic part accommodating chamber 11f and the slit 11k.

  As shown in FIGS. 1 to 4, 11, and 13, four rectangular fitting holes 11 g are formed in the lower portions at both ends of the side wall portion 11 a so as to penetrate the side wall portion 11 a. The fitting hole 11g engages with the protrusion 12a of the movable housing 12 to limit the movable distance δ1 in the Y direction and the movable distance δ2 in the Z direction. An uneven surface is formed on the lower surface. The movable displacement distance δ1 in the Y direction and the movable distance δ2 in the Z direction of the movable housing 12 are determined by a gap between the fitting hole 11g and the protrusion 12a fitted to the fitting hole 11g. Is approximately 0.5 mm, and the displaceable distance δ2 in the Z direction is set to approximately 0.1 mm.

  Note that the upper and lower surfaces of the fitting hole 11g are uneven. The ribs are provided on a mold (not shown) for removing the fitting hole 11g when the fixed housing 11 and the movable housing 12 are simultaneously formed. This is to increase the mechanical strength of the mold. Further, when the movable housing 12 is displaced with respect to the fixed housing 11, the contact area between the fitting hole 11g and the protrusion 12a is reduced to reduce the sliding resistance, and the displacement of the movable housing 12 is smoothed. Have.

  As shown in FIGS. 2, 4, and 5, two positioning pins 11 h are protruded from the lower surface of the fixed housing 11, and are fitted into positioning holes 14 a provided in the printed circuit board 14. The printed circuit board 14 is positioned. Further, a slot 11i for mounting the fixing bracket 16 is formed in the side wall portion 11b of the fixed housing 11 from the lower surface to the upper surface of the fixing housing 11. The fixing bracket having an L-shaped cross section is formed in the slot 11i. 16 is inserted and mounted. The lower surface of the fixing bracket 16 is the same surface as the lower surface of the fixed housing 11, and the fixed housing 11 can be firmly fixed to the printed circuit board 14 by soldering to the printed circuit board 14.

  As shown in FIGS. 1, 3, and 5, the movable housing 12 is disposed in the rectangular through hole 11 c of the fixed housing 11 and is fitted with the mating connector 30 fixed to the other printed circuit board 24. And is disposed so as to be displaceable with respect to the fixed housing 11. The movable housing 12 is formed by injection molding a synthetic resin having electrical insulation.

  Further, referring to FIG. 6, the movable housing 12 is provided with a separation wall portion 12b along the longitudinal direction at the center in the short side direction, and the separation wall portion between the separation wall portion 12b and the side wall portion 12c. Two slit-shaped chambers partitioned by 12b are formed. And the connection terminal (male connection terminal) 31 of the other party connector 30 is received in a slit-shaped chamber.

  In the separation wall portion 12b and the side wall portion 12c, a plurality of partition walls 12d are formed along the separation wall portion 12b and the side wall portion 12c in a direction perpendicular to the side wall portion 12b. As a result, a large number of contact portion accommodating chambers 12e are formed between the adjacent partition walls 12d at a predetermined interval (for example, 30 pieces at an interval of 0.8 mm), and the connection terminals 13 are connected to the respective contact portion accommodating chambers 12e. The end portion is inserted and accommodated.

  As shown in FIGS. 3, 4, and 7, four projecting portions 12 a having a rectangular cross section are provided on both sides of the lower portion of the side wall portion 12 c of the movable housing 12 so as to protrude laterally. Are freely fitted in the fitting holes 11g. That is, the fitting hole 11g and the protrusion 12a are loosely fitted with a Y-direction gap 2 × δ1 and a Z-direction gap 2 × δ2 (see FIG. 11). When the movable housing 12 is displaced in the Y direction or the Z direction (see FIG. 1) with respect to the fixed housing 11, the protrusion 12a abuts on the fitting hole 11g to limit the amount of displacement of the movable housing 12, which is excessive. It is designed to prevent any displacement. In other words, the excessive displacement prevention mechanism 18 is configured by the fitting hole 11g and the protrusion 12a.

  As shown in FIG. 6, a plurality of hemispherical protrusions 12f are provided on the lower surface of the movable housing 12, and when the movable housing 12 is displaced, it slides on the printed circuit board 14 to reduce the resistance force. Displacement of the movable housing 12 is facilitated. Further, as shown in FIGS. 3 and 5, the fixed housing 11 and the movable housing 12 are made of synthetic resin in an integrated shape connected by the connecting portion 19 in a state where the protruding portion 12a is loosely fitted in the fitting hole 11g. It is formed by injection molding. The connecting portion 19 is later cut away so that the movable housing 12 is separated from the fixed housing 11. This is for reasons of assembly, and the assembly will be described in detail later.

  As shown in FIGS. 1, 2, and 6, the connection terminal 13 electrically connects a conductive pattern (not shown) of one printed circuit board 14 and a conductive pattern (not shown) of the other printed circuit board 24. And is formed by pressing a conductive metal plate and has a spring property. The connection terminal 13 is formed in a substantially vertical direction with respect to the contact portion 13a connected to the connection terminal 31 disposed in the counterpart connector 30, and is soldered to the conductive pattern of the printed circuit board 14. A leg portion 13b to be connected and an elastic portion 13c formed in an inverted U shape (U shape in FIG. 2) are integrally formed between the contact portion 13a and the leg portion 13b.

  As shown in FIGS. 2 and 6, the connection terminal 13 is a female connection terminal, the contact portion 13 a is formed in a tuning fork shape (that is, a bifurcated shape), and the male connector disposed in the mating connector 30. The connection terminal 31 is sandwiched between the two forks so as to make a reliable contact. In addition, the elastic portion 13c formed in an inverted U shape is provided with a spring property on the connection terminal 13 by elastic deformation of the inverted U shape portion.

  As shown in FIG. 2, the plurality of connection terminals 13 are inserted and attached in the direction of arrow C from the bottom surface side of the fixed housing 11 and the movable housing 12 that are connected by the connecting portion 19 and are integrally formed. The That is, the contact portion 13a is inserted into the contact portion receiving chamber 12e of the movable housing 12 partitioned by the partition wall 12d, and the elastic portion 13c and the leg portion 13b are respectively accommodated by the elastic portion of the fixed housing 11 partitioned by the partition wall 11e. After being inserted and attached to the chamber 11f and the slit 11k, the connecting portion 19 is cut off by an appropriate tool, and the movable housing 12 is separated from the fixed housing 11. As a result, the movable housing 12 is supported so as to be displaceable with respect to the fixed housing 11 by, for example, 60 connection terminals 13 arranged in two rows of 30 at intervals of 0.8 mm. Each connection terminal 13 is mounted in a state of being electrically insulated from each other by being separated from each other by a partition wall 11e and a partition wall 12d.

  The fixed housing 11 and the movable housing 12 are integrally formed by connecting with the connecting portion 19 in a state where the protruding portion 12a is loosely fitted in the fitting hole 11g, and after the connecting terminal 13 is mounted, the connecting portion 19 is attached. Even if the protrusion 12a of the movable housing 12 is longer than the inner dimension of the fixed housing 11, the fitting hole 11g can be removed. It can be easily assembled in a state in which the protrusion 12a is loosely fitted.

  The operation of this embodiment will be described. As shown in FIG. 1, the connector 10 of the present invention is formed by fitting a mating connector 30 disposed on the other printed circuit board 24 into the connector 10 disposed on one printed circuit board 14. The bifurcated contact portion 13a of the connection terminal 13 disposed on the movable housing 12 firmly holds the male connection terminal 31 of the mating connector 30, and the conductive pattern of one printed circuit board 14 and the other printed circuit. The conductive pattern of the substrate 24 is securely connected.

  Since the contact portion 13a of the connection terminal 13 holds the counterpart male connection terminal 31 at two points on both side surfaces, the movable housing 12 is fixed to the fixed housing 11 as compared with the conventional connector that contacts on one side. The contact pressure between the connection terminal 13 and the mating male connection terminal 31 does not change even when the connection is displaced, and the electrical connection is maintained well. Further, the contact point does not slide due to the displacement of the movable housing 12. Therefore, fine wear at the contact point does not occur, and a highly reliable connection is possible over a long period of time.

  Here, if there is a position error between the connector 10 and the counterpart connector 30, the movable housing 12 is displaced with respect to the fixed housing 11 to absorb the position error, and the connector 10 and the counterpart connector 30 are fitted. Accordingly, the connection terminal 13 comes into contact with the male connection terminal 31 disposed in the counterpart connector 30 and is securely connected.

  6 and 7 show a normal state in which the movable housing 12 is not displaced in the X direction (see FIG. 1) with respect to the fixed housing 11, and the shape of the elastic portion 13c of the connection terminal 13 is symmetrical. It has become. At this time, as shown in FIG. 7, a gap is formed between the inner wall surface of the side wall portion 11a and the lower side wall portion 12g of the movable housing 12, and a displaceable distance δ3 is secured. The displaceable distance δ3 is set to 0.5 mm, for example.

  When the mating connector 30 having a position error in the X direction is inserted, as shown in FIGS. 8 and 9, the inverted U-shaped elastic portion 13c of the connection terminal 13 is deformed, that is, one inverted U-shaped portion. Is deformed in the direction in which the width is increased, and the other inverted U-shaped portion is deformed in the direction in which the width is reduced, and the movable housing 12 is displaced in the X direction with respect to the fixed housing 11 to follow the mating connector 30, thereby Absorb. The maximum movable distance of the movable housing 12 is a displaceable distance δ3, and beyond that, the lower side wall portion 12g of the movable housing 12 abuts on the inner wall surface of the side wall portion 11a and is limited (FIG. 9). Therefore, an excessive stress does not act on the connection terminal 13 due to the displacement of the movable housing 12. This also prevents an excessive force applied to the slit 11k that supports one end (leg side) of the connection terminal 13, and the slit 11k is not damaged.

  Further, as shown in FIG. 8, the connection terminal 13 is housed in an elastic part housing chamber 11f in which the elastic part 13c is partitioned by the partition wall 11e, so that even if the elastic part 13c is deformed. There is no possibility that the adjacent connection terminals 13 contact each other. In addition, since each elastic portion accommodating chamber 11f is opened to the outside of the fixed housing 11 through the long hole 11d, the elastic portion 13c can be deformed while projecting to the outside of the fixed housing 11, and the elastic portion 13c can be elastically deformed. The part 13c does not interfere with the side wall part 11a. Therefore, the fixed housing 11 (that is, the connector 10) can be downsized together with the prevention of contact between the connection terminals 13 by the partition wall 11e.

  10 and 11 show a normal state in which the movable housing 12 is not displaced in the Y direction (see FIG. 1) with respect to the fixed housing 11, and the protrusion 12a is located at the center in the left-right direction of the fitting hole 11g. Located between the protrusion 12a and the fitting hole 11g, a gap of a displaceable distance δ1 is evenly formed on the left and right.

  When the mating connector 30 having a position error in the Y direction is inserted, as shown in FIGS. 12 and 13, the connection terminal 13 is bent mainly in the Y direction by the elastic portion 13 c, and the movable housing 12 is moved to the fixed housing 11. On the other hand, it is displaced in the Y direction and follows the counterpart connector 30. The maximum movable distance of the movable housing 12 is the displaceable distance δ1, and beyond that, the protruding portion 12a abuts on the fitting hole 11g (see FIG. 13) and is restricted, so that excessive stress acts on the connection terminal 13. There is nothing. Further, each connection terminal 13 is separated from each other in the elastic portion accommodating chamber 11f partitioned by the partition wall 11e, and is accommodated in a narrow gap, so that deformation of the connection terminal 13 in the Y direction is restricted and adjacent to each other. The connecting terminals 13 that do not come into contact with each other. Accordingly, excessive stress acting on the connection terminal 13 is also prevented by this, and the force applied to the slit 11k that supports one end of the connection terminal 13 is also limited.

  As shown in FIG. 1, when the mating connector 30 is inserted into or removed from the connector 10, an insertion / extraction force in the Z direction acts on the connector 10. As shown in FIG. 11, the gap in the Z direction between the protrusion 12a and the fitting hole 11g is extremely narrow (for example, 0.1 mm) and is a displaceable distance δ2. Therefore, when the mating connector 30 is inserted, as soon as the connection terminal 13 is slightly deformed, the lower surface of the projection 12a comes into contact with the lower surface of the fitting hole 11g. Further, when the mating connector 30 is removed from the connector 10, as soon as the connection terminal 13 is slightly deformed, the upper surface of the protrusion 12a abuts on the upper surface of the fitting hole 11g and the movement is restricted.

  As a result, the insertion / extraction force of the mating connector 30 is received by the protrusion 12 a and the fitting hole 11 g, and excessive stress does not act on the connection terminal 13. The insertion / extraction force of the mating connector 30 is received by the fixed housing 11 via the protrusion 12a and the fitting hole 11g. The fixed housing 11 is firmly attached to the printed circuit board 14 by the two positioning pins 11h and the fixing bracket 16. Since it is fixed, it can easily withstand the insertion / extraction force.

  As described above, according to the present embodiment, the fixed housing 11 is formed on the side wall portion 11a, the side wall portion 11a, and the side wall portion so as to form a plurality of elastic portion accommodating chambers 11f in the side wall portion 11a. 11a, and the elastic portions 13c of the plurality of connection terminals 13 are respectively accommodated in the elastic portion accommodating chambers 11f of the fixed housing 11, so that the elastic portions 13c of the plurality of connection terminals 13 are accommodated. Can be individually separated by a partition wall and placed in the elastic portion accommodating chamber 11f. Therefore, there is no possibility that the connection terminals come into contact with each other when the movable housing 12 is displaced with respect to the fixed housing 11, and a measure for preventing the connection terminal 13 from being short-circuited is ensured. Therefore, downsizing of the connector 1 can be realized.

  In addition, according to the present embodiment, the side wall portion 11a of the fixed housing 11 communicates from the elastic portion accommodating chamber 11f to the outside of the fixed housing 11 and allows the elastic displacement of the elastic portion 13c toward the outside of the fixed housing 11. Since the formed through-hole 11d is provided, the elastic part 13c of the connection terminal 13 does not interfere with the side wall part 11a of the fixed housing 11 and the elastic deformation is not hindered, and the degree of freedom of the elastic deformation is increased. That is, since the through hole 11d is formed in the side wall portion 11a of the fixed housing 11 so as to penetrate the elastic portion 13c of the connection terminal 13 in the elastic displacement direction, the movable housing 12 can be fixed even if the connector 1 is downsized. A sufficient amount of displacement with respect to the housing 11 can be obtained (in other words, regulation of elastic deformation of the connection terminal 13 by the side wall portion 11a of the fixed housing 11 can be reduced).

  Further, according to the present embodiment, the fixed housing 11 can be fixed to one electric circuit board 14, and the leg portions 13 b of the plurality of connection terminals 13 can be electrically connected to the one electric circuit board 14. Since the movable housing 12 can be fitted to the mating connector 30 that can be fixed to the other electric circuit board 24, a connector suitable for board-to-board connection can be provided.

  The present invention is not limited to the above-described embodiments, and modifications, improvements, etc. can be made as appropriate. In addition, the material, shape, dimension, numerical value, form, number, arrangement location, and the like of each component in the above-described embodiment are arbitrary and are not limited as long as the present invention can be achieved.

  In the above embodiment, the connector for connecting the two printed circuit boards so as to be arranged in parallel has been described. However, the present invention is not limited to this. For example, the two printed circuit boards are arranged vertically. Needless to say, the present invention can also be applied to such connectors.

  Moreover, although the board-to-board connector has been described as an example in the above embodiment, the present invention is not limited to this. For example, the cable is disposed at the end of the cable to electrically connect the cables. The present invention can be effectively applied to other types of connectors such as a connector to be used.
