  The power supply side terminal portion 55 is held by the movable housing 3 and is electrically connected to the mating connector 100. The power supply side terminal portion 55 is formed by being bent at a right angle with respect to each second power supply side elastic portion 54. The power supply side terminal portion 55 extends upward (substantially vertically upward) from the inner end of each second power supply side elastic portion 54. The power supply side terminal portion 55 is press-fitted into the power supply movable side press-fitting groove 28 formed in the movable column portion 25 (see FIG. 3). On the left and right side surfaces of the power supply side terminal portion 55, three pairs of left and right power supply terminal side press-fitting protrusions 59 are formed at predetermined intervals in the vertical direction. The length of the power supply side terminal portion 55 in the vertical direction is slightly longer than the height of the movable main body wall 23.

Each of the first power supply side elastic portions 52 and each of the second power supply side elastic portions 54 have a lateral width that allows flexible elastic deformation. The left and right widths of the power supply side wide portions 53 are formed to have the same width. The left and right widths of the power supply side wide portions 53 are formed wider than the first power supply side elastic portions 52 and the second power supply side elastic portions 54. Further, the left and right widths of the respective power supply side wide portions 53 are formed wider than the interval P2.

  Next, the assembly process of the connector 1 will be described with reference to FIGS.

  First, the plurality of connection terminals 4 are fixed to the movable housing 3. The user fixes the movable housing 3 and each connection terminal 4 to a predetermined position on the lower side of the movable housing 3 so that the plurality of connection terminals 4 (two terminal rows 40) arranged at equal intervals face each other (see FIG. (Not shown). Then, the terminal portions 45 of the connection terminals 4 are made to enter the respective terminal insertion holes 27 (each movable-side press-fit groove 26) opened side by side in the left-right direction upward. In addition, the attachment operation | work of each terminal part 45 with respect to the movable housing 3 is performed substantially simultaneously about the some connection terminal 4 using a comb-shaped attachment jig (not shown). When the mounting jig is moved upward, each terminal portion 45 is pushed into each movable side press-fitting groove 26 of the movable housing 3.

  As each terminal portion 45 advances, the upper two sets of terminal-side press-fit protrusions 49 are press-fitted into the movable-side press-fit groove 26. Thereby, the plurality of terminal portions 45 are held in the movable side press-fitting grooves 26 in a state of being prevented from being detached. In this state, the terminal-side press-fitting protrusions 49 at the lowermost ends are positioned below the movable-side press-fitting groove 26.

  As described above, the terminal row 40 is fixed to the movable housing 3. In addition, the fixing operation | work of each terminal row | line 40 with respect to the movable housing 3 may be performed substantially simultaneously about a pair of front and back terminal row | line | column 40, and may be performed separately.

  Similarly, four power supply terminals 5 are fixed to the movable housing 3. The user holds the movable housing 3 and each power supply terminal 5 on a fixing jig (not shown) so that each power supply terminal 5 faces a predetermined position below the movable housing 3. And the power supply side terminal part 55 of each power supply terminal 5 is made to approach toward each power supply insertion hole 30d (each power supply movable side press-fit groove 28) upward. In addition, the attachment work of each power supply side terminal part 55 is also performed substantially simultaneously about the four power supply terminals 5 using the attachment jig mentioned above. When the mounting jig is moved upward, each power supply side terminal portion 55 is pushed into each power supply movable side press-fitting groove 28.

  When the entry of each power supply side terminal portion 55 proceeds, the two sets of power supply terminal side press-fitting protrusions 59 on the upper side are press-fitted into the power supply movable side press-fit groove 28. As a result, the four power supply side terminal portions 55 are held in the respective power supply movable side press-fitting grooves 28 while being prevented from being detached. In this state, the power supply terminal side press-fitting protrusions 59 at the lowest end are positioned below the power supply movable side press-fitting groove. Further, the fixing operation of each power supply side terminal portion 55 to the movable housing 3 may be performed substantially simultaneously with the fixing of each terminal row 40 or may be performed before or after the fixing of each terminal row 40.

  Next, the movable housing 3 to which the pair of front and rear terminal rows 40 and the four power supply terminals 5 are fixed is supported by the fixed housing 2. First, the user holds the fixed housing 2 and the movable housing 3 on a fixing jig (not shown) so that the movable housing 3 faces a predetermined position below the fixed housing 2. Then, the movable housing 3 is advanced from the lower end of the fixed side opening 10 upward.

  The attaching operation of each connecting portion 41 to the fixed housing 2 is performed in substantially the same manner as the attaching operation of each terminal portion 43 to the movable housing 3. By moving the mounting jig upward, each connection portion 41 (each connection-side press-fit portion 41b) is pushed into each fixed-side press-fit groove 14, and each power-supply-side connection portion 51 (each power-supply-side press-fit portion 51b) It is pushed into the power fixing side press-fitting groove 15.

  As the movable housing 3 advances (pushes in), the upper two sets of connection-side press-fitting protrusions 47 provided in the connection-side press-fit portions 41b are press-fitted into the fixed-side press-fit groove 14. At approximately the same time, the two sets of power supply connection side press-fitting protrusions 57 provided in the power supply side press-fitting portions 51b are press-fitted into the power supply fixing side press-fitting groove 15. Then, when a predetermined amount of press-fitting is performed, each connection-side press-fit portion 41b is held in the fixed-side press-fit groove 14 in a retaining state, and each power-supply-side press-fit portion 51b is retained in the power-fixing-side press-fit groove 15 in a retaining state. Retained. In this state, the connection-side press-fitting protrusions 47 at the lowest end are located below the fixed-side press-fitting groove 14.

  Thus, the assembly of the connector 1 is completed. The assembled connector 1 is arranged on the board B1, and the board mounting portions 41a of the connection terminals 4, the power supply side mounting portions 51a of the power terminals 5, and the metal legs 16a of the fixing brackets 16 are respectively soldered. The

  In a state where the assembly of the connector 1 is completed, the movable main body portion 21 of the movable housing 3 is positioned above the upper end surface of each extending wall 12 of the fixed housing 2. In this state, a slight gap is formed between the lower end surface of each fixed main body wall 11 and the board mounting portion 41 a of each connection portion 41. That is, in a state where the connector 1 is mounted on the board B1, the fixed housing 2 is fixed at a position slightly raised from the board B1 via the connection terminals 4 and the like.

  Further, in a state where the assembly of the connector 1 is completed, each connection terminal 4 is bridged between the fixed housing 2 and the movable housing 3, and each first elastic portion 42, each wide portion 43 and each second elastic portion. Reference numerals 44 denote exposed portions in contact with air in the fixed-side opening 10. Further, air is interposed between the adjacent portions 42 to 44 (interval P1). Each 1st elastic part 42 is set to the length which can space apart the wide part 43 from the fixed side inner wall surface 11b. Each second elastic portion 44 extends inward from the upper end portion of the wide portion 43 inclined outward, and is set to a length that allows the terminal portion 45 to be introduced into the movable-side press-fit groove 26.

  Similarly, each power supply terminal 5 is bridged between the fixed housing 2 and the movable housing 3, and each first power supply side elastic portion 52, each power supply side wide portion 53, and each second power supply side elastic portion 54 is The exposed portions are in contact with the air in the fixed-side opening 10 and the moving space S2, respectively. Air is interposed between adjacent portions 52 to 54 (interval P2). Each of the first power supply side elastic portions 52 is set to a length capable of separating the power supply side wide portion 53 from the fixed side inner wall surface 12c. Each of the second power supply side elastic portions 54 extends inward from the upper end portion of the power supply side wide portion 53 inclined outward, and is set to a length that allows the power supply side terminal portion 55 to be introduced into the power supply movable side press-fit groove 28. .

  In the connector 1, the elastic housings 42, 44 and the power supply side elastic members 52, 54 are elastically deformed, so that the movable housing 3 moves forward, backward, left and right with respect to the fixed housing 2. To be exact, in each connection terminal 4, a bent portion between each connection portion 41 (connection-side press-fit portion 41 b) and each first elastic portion 42, and between each first elastic portion 42 and each wide portion 43. Since stress concentrates on the bent portions, the bent portions are mainly elastically deformed. Similarly, the bent portion between each wide portion 43 and each second elastic portion 44 and the bent portion between each second elastic portion 44 and each terminal portion 45 are mainly elastically deformed. Further, in each power supply terminal 5, a bent portion between each power supply side connection portion 51 (power supply side press-fit portion 51b) and each first power supply side elastic portion 52, and each first power supply side elastic portion 52 and each power supply side. The bent part between the wide part 53 and the main part is elastically deformed mainly. Similarly, a bent portion between each power supply side wide portion 53 and each second power supply side elastic portion 54 and a bent portion between each second power supply side elastic portion 54 and each power supply side terminal portion 55 are: Mainly elastically deforms. As described above, the movable housing 3 of the connector 1 is supported by the plurality of connection terminals 4 and the plurality of power supply terminals 5 in a state in which the movable housing 3 can move back and forth and right and left within the fixed-side opening 10 of the fixed housing 2.

  The pair of left and right movable leg portions 22 of the movable housing 3 are provided in the left and right end regions of the fixed side opening 10. A predetermined gap G1 is formed between the outer surface of each movable leg 22 and the inner peripheral wall surface of the fixed opening 10 (see FIG. 3). Further, on both the front and rear sides, each fixed main body wall 11 is positioned with a predetermined gap between the inner inclined surfaces 30b of the pair of left and right movement restriction blocks 30. The lower inclined surface 30 c of each movement restriction block 30 is formed at an angle corresponding to each upper inclined surface 11 a of each fixed main body wall 11.

  Although not shown, each engagement block 31 formed on each movable leg 22 is loosely fitted in an engagement space S1 formed on the lower side of the lateral protrusion 13a of each substrate fixing portion 13. ing. The upper surface of each engagement block 31 comes into contact with the top surface of the engagement space S1 (the lower surface of the lateral ridge 13a), so that the movable housing 3 does not slip upward with respect to the fixed housing 2. . A gap substantially the same as the gap G1 described above is formed between the left and right side surfaces of each engagement block 31 and the left and right side surfaces of the engagement space S1.

  Therefore, the movable housing 3 is configured to be able to move back and forth and right and left within a predetermined gap G1 inside the fixed side opening 10 of the fixed housing 2. In other words, the outer surface of each movable leg portion 22 abuts on the inner peripheral wall surface of the fixed-side opening 10, and the side surface of each engagement block 31 abuts on the side surface of the engagement space S1. The movement beyond a predetermined range is regulated.

  Next, the connection between the connector 1 and the mating connector 100 will be briefly described with reference to FIG.

  The mating connector 100 has a plurality of mating terminals 101 and four mating power terminals 102. The plurality of mating terminals 101 form two mating terminal rows L arranged at equal intervals in the left-right direction. The mating connector 100 includes a mating housing 103 having a mating opening (not shown) whose bottom surface is opened, and a mating fitting portion that is installed in the mating opening and holds each mating terminal row L. (Not shown).

  When connecting the connector 1 to the counterpart connector 100, the user enters the movable housing 3 of the connector 1 into the counterpart opening of the counterpart connector 100. The approach of the movable housing 3 is guided by a pair of left and right fitting guide portions 25a. On the other hand, the mating fitting portion enters the movable opening 20 while being guided by the pair of left and right guide inclined surfaces 25b and the pair of left and right guide grooves 25c of the movable housing 3. Thereby, each counterpart terminal 101 and the terminal portion 45 of each connection terminal 4 come into contact with each other, and each counterpart power terminal 102 and the power supply side terminal portion 55 of each power supply terminal 5 come into contact. The pair of substrates B1 and B2 are electrically connected.

  In this connector 1, each elastic part 42, 44 and each power supply side elastic part 52, 54 are elastically deformed, so that the movable housing 3 moves with respect to the fixed housing 2. A positional deviation with respect to the side terminal 101 and a positional deviation between each power supply terminal 5 and the counterpart power supply terminal 102 are allowed and appropriate connections are made. In addition, the lower end surface of the counterpart housing 103 is in contact with the upper surface of each movement restriction block 30 in a state where the connectors 1 and 100 are connected. Thereby, the movement of the mating connector 100 with respect to the connector 1 in the fitting direction is restricted.

  According to the connector 1 according to the first embodiment of the present invention described above, the wide portion 43 of each connection terminal 4 is exposed between the fixed housing 2 and the movable housing 3, and the first elastic portion 42 and It is formed wider than the second elastic portion 44 in the left-right direction (parallel direction). Therefore, each wide part 43 has a larger cross-sectional area than each elastic part 42 and 44, and the space | interval P1 of the adjacent wide parts 43 becomes comparatively narrow. Therefore, at least one of impedance matching at each connection terminal 4 and impedance matching between the paired connection terminals 4 can be performed. As a result, disturbance of the high-frequency signal due to impedance mismatch is prevented, and high-speed transmission of the high-frequency signal can be performed appropriately. This is particularly effective when a differential transmission method is used.

  Similarly, the three power supply side wide portions 53 of each power supply terminal 5 are also exposed between the fixed housing 2 and the movable housing 3, and from the first power supply side elastic portion 52 and the second power supply side elastic portion 54. Is also widely formed in the left-right direction (parallel direction). Therefore, each power supply side wide part 53 has a larger cross-sectional area than each power supply side elastic part 52, 54, and the space | interval of adjacent power supply side wide parts 53 becomes comparatively narrow. The three first power supply side elastic portions 52 are connected by a power supply side connection portion 51 (power supply side press-fit portion 51b), and the three second power supply side elastic portions 54 are connected by a power supply side terminal portion 55. Furthermore, since the three power source side wide portions 53 are formed wider than the power source side elastic portions 52 and 54, a relatively large current can flow.

  Further, the first elastic portion 42 and the second elastic portion 44 formed so as to be bent with respect to each wide portion 43 are formed narrower than the wide portion 43. Similarly, each first power supply side elastic portion 52 and each second power supply side elastic portion 54 are formed narrower than each power supply side wide portion 53. For this reason, each elastic part 42 and 44 and each power supply side elastic part 52 and 54 can be elastically deformed flexibly. Thereby, the movable housing 3 can move smoothly with respect to the fixed housing 2.

  Moreover, according to the connector 1 which concerns on 1st Embodiment of this invention, with respect to the wide part 43 of each connecting terminal 4, the 1st elastic part 42 and the 2nd elastic part 44 are bent in the mutually opposite direction. The wide portions 43 and the elastic portions 42 and 44 form acute angles (respective angles θ1 and θ2). That is, the wide part 43 and each elastic part 42 and 44 are formed in the substantially Z shape. For this reason, the extension line S (refer to the one-dot chain line in FIG. 5) extending vertically upward from the position where each connection portion 41 is held (press-fit) in the fixed housing 2, and each terminal portion 45 is held (press-fit) in the movable housing 3. The distance D (displacement in the front-rear direction) from the position is reduced. As described above, since the offset amount is reduced, it is possible to prevent the first elastic portion 42 and the second elastic portion 44 from being excessively deformed when the movable housing 3 is moved. Thereby, the movement of the movable housing 3 relative to the fixed housing 2, in particular, the movement in the front-rear direction (the bending direction of the first elastic portion 42 and the second elastic portion 44) can be performed more smoothly. Each power supply terminal 5 can also be smoothly moved in the front-rear direction for the same reason.

  The number of connection terminals 4 and power supply terminals 5 is arbitrary. The number of the first power supply side elastic portion 52, the power supply side wide portion 53, and the second power supply side elastic portion 54 of each power supply terminal 5 is also arbitrary. In addition, although the left-right width | variety of the several power supply side elastic parts 52 and 54 mentioned above was formed in the same width, respectively, it is not limited to this, You may form in different left-right width, respectively. Similarly, the left and right widths of the plurality of power supply side wide portions 53 are formed to have the same width, but are not limited thereto, and may be formed to have different left and right widths. Further, the angles θ1 and θ2 described above may be a right angle (90 °). However, in order to ensure proper movement, it is preferable that the angles θ1 and θ2 be acute angles as described above.

  In addition, although the connector 1 which concerns on 1st Embodiment mentioned above was mounted in board | substrate B1 in the standing posture, for example, connector 1 is turned sideways so that the connection direction with the other party connector 100 may become parallel to board | substrate B1. You may mount to board | substrate B1 by attitude | position. In this case, a pair of left and right extending walls 12 (parallel portion 12b) formed in either one of the front and rear directions of the fixed housing 2 abut on the substrate B1. And the connection part 41 (board | substrate mounting part 41a) of each connection terminal 4 and the power supply side connection part 51 (power supply side mounting part 51a) of each power supply terminal 5 are each extended toward the board | substrate B1, and soldering is performed. .

The wide portion 93 extends forward from the upper end portion of the first elastic portion 92 and is formed substantially parallel to the substrate B3. The length of the wide portion 93 in the front-rear direction is formed substantially the same as the length of the fixed housing 7 in the front-rear direction.

  The second elastic portion 94 is formed by being bent at a right angle with respect to the wide portion 93. The second elastic portion 94 extends upward from the front end portion (one side end portion) of the wide portion 93 and is formed to be elastically deformable. The length of the second elastic portion 94 in the vertical direction is formed substantially the same as the thickness of the movable main body wall 84.

  Therefore, the wide part 93 described above is connected between the first elastic part 92 and the second elastic part 94 so that the first elastic part 92 and the second elastic part 94 are bent in opposite directions. The left and right widths of the respective parts constituting the connection terminal 9 are such that the connection part 91, the first elastic part 92, and the second elastic part 94 are formed with the same width, and the wide part 93 and the terminal part 95 are formed with the same width. Has been. That is, the wide portion 93 is formed wider in the left-right direction (parallel arrangement direction) than the first elastic portion 92 and the second elastic portion 94.

  The terminal portion 95 is formed by being bent at a right angle with respect to the second elastic portion 94. The terminal portion 95 extends from the upper end portion of the second elastic portion 94 toward the front (one side) and is formed substantially parallel to the substrate B3. The terminal portion 95 is press-fitted into a movable-side press-fitting groove 87 formed on the movable-side inner wall surface 84a (see FIG. 10). On the left and right side surfaces of the rear portion of the terminal portion 95, three pairs of left and right terminal-side press-fitting protrusions 99 are provided in the vertical direction in the same manner as the terminal portion 45 according to the first embodiment. In addition, a tapered portion 95 a that is chamfered on three sides except the outside is formed at the front end portion of the terminal portion 95.

  The length in the extending direction of the portions 91 to 95 constituting the connection terminal 9 is arbitrarily set according to the length of the press-fit grooves 72 and 87, the thickness of the housings 7 and 8, and the like.

  Next, the assembly process of the connector 6 will be briefly described with reference to FIGS.

  First, the plurality of connection terminals 9 are fixed to the movable housing 8. The user holds the movable housing 8 and each connection terminal 9 on a fixing jig (not shown) so that a plurality of connection terminals 9 arranged at equal intervals face a predetermined position on the rear side of the movable housing 8. And the terminal part 95 of each connection terminal 9 is approached toward the front with respect to each terminal insertion hole 88 (each movable side press-fit groove 87). The attaching operation of each terminal portion 95 to the movable housing 8 is performed using an attaching jig, similarly to the assembling operation of the connector 1 according to the first embodiment. Each terminal-side press-fitting protrusion 99 of each terminal portion 95 is press-fitted into the movable-side press-fitting groove 87, whereby each terminal portion 95 is held in a state of being prevented from coming off.

  Next, the movable housing 8 to which the terminal row 90 is fixed is supported by the fixed housing 7. First, the user holds the fixed housing 7 and the movable housing 8 on a fixing jig (not shown) so that the movable housing 8 faces a predetermined position below the fixed housing 7. Then, the movable housing 8 is advanced upward from the lower end of the fixed side opening 70, and each connection portion 91 (each connection side press-fit portion 91 b) is pushed into each fixed-side press-fit groove 72. This operation is also performed using an attachment jig, similarly to the assembly operation of the connector 1 according to the first embodiment. Each connection side press-fit protrusion 97 of each connection-side press-fit portion 91b is press-fitted into each fixed-side press-fit groove 72, whereby each connection portion 91 is held in a state of being prevented from coming off.

  Thus, the assembly of the connector 6 is completed. The assembled connector 6 is arranged on the board B3, and the board mounting part 91a of each connection terminal 9 and the metal leg part 16a of each fixing metal 16 are soldered.

  In a state where the assembly of the connector 1 is completed, the movable housing 8 and the fixed housing 7 are arranged in parallel to the board B3, and the movable main body 81 of the movable housing 8 is located in front of the front end surface of the fixed housing 7. ing. In this state, each contact surface portion 7a of the fixed housing 7 abuts on the substrate B3, and a slight gap is formed between the rear lower end surface of the fixed housing 7 and the substrate mounting portion 91a of each connection portion 91. ing. That is, with the connector 6 mounted on the board B3, the fixed housing 7 is fixed at a position slightly raised from the board B3 via the connection terminals 9. The movable housing 8 is also supported at a position slightly lifted from the substrate B3.

  Further, in a state where the assembly of the connector 6 is completed, each connection terminal 9 is bridged between the fixed housing 7 and the movable housing 8, and each first elastic portion 92, each wide portion 93 and each second elastic portion. Reference numerals 94 denote exposed portions in contact with air in the fixed-side opening 70. Air is interposed between the adjacent portions 92 to 94. In the connector 6, the elastic portions 92 and 94 are elastically deformed, so that the movable housing 8 moves vertically and horizontally with respect to the fixed housing 7. Precisely, since stress concentrates on a bent portion between each first elastic portion 92 and each wide portion 93, the bent portion is mainly elastically deformed. Similarly, the bent portion between each wide portion 93 and each first elastic portion 92 and the bent portion between each first elastic portion 92 and each terminal portion 45 are mainly elastically deformed. As described above, the movable housing 8 of the connector 6 is supported by the plurality of connection terminals 9 so as to be movable vertically and horizontally within the fixed-side opening 70 of the fixed housing 7.

  Similarly to the connector 1 according to the first embodiment, the pair of left and right movable legs 82 of the movable housing 8 are provided in the left and right end regions of the fixed side opening 70 with a gap G2 (see FIG. 10). ). In addition, the engagement blocks 82b formed in each movable leg 82 are loosely fitted in the engagement space S3 (see FIG. 10) formed in the fixed side opening 70 (both side surfaces in the left and right direction of the fixed housing 7). Thus, the movable housing 8 is prevented from coming out forward with respect to the fixed housing 7.

  The connector 6 is fitted to the mating connector 200 and is electrically connected. Note that the structure of the mating connector 200 and the method of connecting the connector 6 and the mating connector 200 are substantially the same as those according to the first embodiment, and a description thereof will be omitted.

  According to the connector 6 which concerns on 2nd Embodiment of this invention demonstrated above, the effect similar to the connector 1 which concerns on 1st Embodiment mentioned above can be acquired. That is, at least one of impedance matching at each connection terminal 9 and impedance matching between the pair of connection terminals 9 can be performed, and high-speed transmission of a high-frequency signal can be appropriately performed. Further, since each of the elastic portions 92 and 94 can be elastically deformed flexibly, the movable housing 3 can be smoothly moved with respect to the fixed housing 2. The number of connecting terminals 9 is arbitrary.

  As shown by a two-dot chain line in FIG. 10, the first elastic portion 92 of the connection terminal 9 is formed in a substantially L shape in a side view, and the connection-side press-fit portion 91 and the first elastic portion 92 are bent. It may be formed.

  In the connector 6 according to the second embodiment, the wide portion 93 of each connection terminal 9 is formed so as to be substantially parallel to the substrate B3. However, the present invention is not limited to this. For example, each wide portion 93 may be inclined (not shown) in the same manner as the wide portion 43 of the connection terminal 4 according to the first embodiment. In this case, the wide portion 93 is preferably inclined downward from the upper end portion of the first elastic portion 92 and extended toward the front (one side). That is, it is preferable that the angle formed by the wide portion 93 and the first elastic portion 92 and the angle formed by the wide portion 93 and the second elastic portion 94 are inclined so as to be acute angles (less than 90 °), respectively.

  According to such a configuration, as with each connection terminal 4 according to the first embodiment, the wide portion 93, the first elastic portion 92, and the second elastic portion 94 are formed in a substantially Z shape. Therefore, an extension line extending horizontally from the position where each connecting portion 91 is press-fitted into the fixed housing 7 toward the front (connecting direction of the mating connector 200) and each terminal portion 95 are press-fitted into the movable housing 8. The distance (shift) from the position is reduced. Thereby, the movable housing 8 can be moved more smoothly in the vertical direction (in the direction connecting the inner side and the outer side) with respect to the fixed housing 7.

  In addition, since description of each embodiment of this invention mentioned above has demonstrated the preferred embodiment in the connector which concerns on this invention, there may be various technically preferable restrictions, but this The technical scope of the invention is not limited to these embodiments unless specifically described to limit the present invention. Furthermore, the components in each embodiment of the present invention described above can be appropriately replaced with existing components and the like, and various variations including combinations with other existing components are possible. The description of each embodiment of the present invention described above is not intended to limit the content of the invention described in the claims.
