Connector and Electronic Device Cross-Reference to Related Applications 【0001】 This application claims the priority of Japanese Patent Application No. 2024-218250, filed in Japan on December 12, 2024, and the entire disclosure of this application is incorporated herein by reference. 【0002】 This disclosure relates to a connector and an electronic device. 【0003】 Conventionally, technologies related to floating board-to-board connectors are known. For example, Patent Document 1 discloses an electrical connector for a circuit board that can reduce the height dimension of the connector while firmly holding terminals integrally formed with a fixed housing and a movable housing respectively, and can increase the amount of elastic deformation at the elastic portion of the terminal. 【0004】 Japanese Patent No. 6727103 【0005】 The connector according to an embodiment of this disclosure includes a contact module having a plurality of contacts each made of metal and arranged in a first arrangement direction, and a first fixing portion and a second fixing portion integrally formed with each of the plurality of contacts. The connector includes a movable insulator attached to an end portion on the second fixing portion side in the contact module, movable relative to the first fixing portion, and fitting with an object to be connected.

This is a top-view perspective view of the connector in Figure 12 when the movable insulator is omitted. 【0008】 In the prior art described in Patent Document 1, there was room for improvement in the method of holding or fixing contacts used for floating movement in connectors. As a result, there was a possibility that the robustness of the connector would decrease during floating movement. 【0009】 According to a connector and electronic device according to one embodiment of the present disclosure, the robustness of the connector is improved when it is floating in motion. 【0010】 This section provides a more detailed explanation of the background and problems of conventional technologies. 【0011】 In recent years, with the increasing demand for high-speed signal transmission within electronic devices, floating board-to-board connectors used for internal connections are also required to have high-speed transmission characteristics. The transmission speed required for board-to-board connectors is increasing year by year. Therefore, further improvements in the transmission characteristics of floating board-to-board connectors are necessary. 【0012】On the other hand, recent floating board-to-board connectors require a large amount of floating movement that exceeds the pitch between contacts. The required amount of movement is increasing year by year. The force generated on the floating contact due to floating movement is absorbed at two points: the fixed-side insulator where the contact locking part is located and the movable-side insulator. In this case, as the amount of floating movement increases, the force applied to the locking part also increases. 【0013】 For example, in order to maintain a stable electrical connection in a connector, the insulator must absorb the force generated by twisting when twisting is applied to the floating contact. This requires holding the contact in place so that there is no angular misalignment of the terminals on both the contact side and the mounting side. To achieve this, it was necessary to increase the holding or fixing force of the contact to the insulator by increasing the length and width of the locking portion. 【0014】 However, increasing the length and width of the locking portion reduces the impedance at the locking portion. This causes impedance mismatch in the connector. Impedance mismatch is a major cause of degradation in transmission characteristics. Therefore, in order to improve both the transmission characteristics and the amount of floating movement compared to conventional floating board-to-board connectors, improvements were needed in the method of holding or fixing the contacts on the floating side. 【0015】 For example, in the circuit board electrical connector described in Patent Document 1, the fixed and movable insulators are integrally molded to the terminal used for floating movement by an insert molding method. In the case of this type of connector, it is not necessary to increase the length and width of the part corresponding to the locking portion. However, due to constraints of the mold structure used for insert molding, there was a portion of the terminal that was held by the insulator, where the insulator was not placed on the surface of the terminal that extended along the surface of the insulator and on the surface opposite to that surface, leaving that surface exposed. 【0016】In such exposed areas, an insulator was placed on only one of a pair of surfaces intersecting the terminal's thickness direction, while the other surface lacked an insulator. A terminal surface was exposed from the insulator in the exposed area. Therefore, if the force applied to the terminal increased due to floating movement, detachment of the terminal from the insulator could occur in the exposed area, potentially leading to damage to the terminal's fixing portion. 【0017】 This disclosure aims to provide connectors and electronic devices with improved robustness during floating operation in order to solve the problems described above. 【0018】 Hereinafter, an embodiment of this disclosure will be described in detail with reference to the attached drawings. In the following description, the directions of front / back, left / right, and up / down are based on the directions of the arrows in the figures. The directions of each arrow are consistent across different drawings in Figures 1 to 5 and Figures 8 to 13. The directions of each arrow are also consistent across different drawings in Figures 6 and 7. In some drawings, for the purpose of simplified illustration, the circuit boards CB1 and CB2, which will be described later, are omitted. 【0019】 Figure 1 is a top-view perspective view of a connector 10 according to one embodiment, showing the state in which the object to be connected 60 is connected. Figure 2 is a top-view perspective view of a connector 10 according to one embodiment, showing the state in which it is separated from the object to be connected 60. For example, as shown in Figure 2, the connector 10 has a pair of contact modules 15 arranged along the front-rear direction, a movable insulator 40, a first fixing bracket 50a and a second fixing bracket 50b, which will be described later. The contact module 15 has a first fixing part 20a as a fixing insulator, a contact 30, and a second fixing part 20b located on the side of the movable insulator 40. The object to be connected 60 has an insulator 70, a contact 80 and a metal member 90. 【0020】In the following, for example, the connector 10 according to one embodiment will be described as a receptacle connector. For example, the object to be connected 60 will be described as a plug connector. A connector 10 in which the contact 30 elastically deforms when the movable insulator 40 of the connector 10 and the insulator 70 of the object to be connected 60 are mated together will be described as a receptacle connector. On the other hand, an object to be connected 60 in which the contact 80 does not elastically deform when mated will be described as a plug connector. 【0021】 As described later, the connector 10 and the object to be connected 60 are mounted on circuit boards CB1 and CB2, respectively. The connector 10 electrically connects circuit board CB2 and circuit board CB1, on which the object to be connected 60 is mounted, via the object to be connected 60 which is mated with the movable insulator 40 of the connector 10. Each of the circuit boards CB1 and CB2 may be a rigid board or any other type of circuit board. For example, at least one of the circuit boards CB1 and CB2 may be a flexible printed circuit board (FPC). 【0022】 In the following description, the connector 10 and the objects to be connected 60 are connected to each other perpendicularly to the circuit boards CB1 and CB2. As an example, the connector 10 and the objects to be connected 60 are connected to each other along the vertical direction. When the movable insulator 40 and the insulator 70 are mated to each other, the mating direction is perpendicular to the circuit board CB1. 【0023】 The connection method is not limited thereto. The connector 10 and the object to be connected 60 may be connected to each other in a direction parallel to the circuit boards CB1 and CB2. The connector 10 and the object to be connected 60 may be connected to each other such that one is perpendicular to the mounted circuit board and the other is parallel to the mounted circuit board. 【0024】In the following explanation, "mating direction" refers to, for example, the up-and-down direction. "First alignment direction" refers to, for example, the left-and-right direction. "Longitudinal direction of connector 10" refers to, for example, the left-and-right direction. "Second alignment direction" refers to, for example, the front-and-back direction. "Shortitudinal direction of connector 10" refers to, for example, the front-and-back direction. "Mating side" refers to, for example, the lower side. "Removal side" refers to, for example, the upper side. 【0025】 "Inside" corresponds to the direction toward the center of the connector 10 or the object to be connected 60. For example, "inside" in the front-to-back direction corresponds to the direction toward the center of the connector 10 or the object to be connected 60 in the front-to-back direction. However, it is not limited to this; "inside" does not have to be a direction toward the center in the front-to-back direction, but may correspond to a direction toward the center at a slight angle. The same applies to other directions. "Outside" is the opposite of "inside". 【0026】 "Mated state" means that the movable insulator 40 of the connector 10 and the insulator 70 of the object to be connected 60 are mated with each other. In the mated state, the contact 30 is in contact with the contact 80 and undergoes elastic deformation. "Unmated state" means that the movable insulator 40 of the connector 10 and the insulator 70 of the object to be connected 60 are not mated with each other. In the unmated state, the contact 30 is not elastically deformed by external force. 【0027】 In one embodiment, the connector 10 has a floating structure. The connector 10 allows the connected object 60 to move relative to the circuit board CB1 along at least one of six directions: up, down, front, back, left, and right. Even when connected to the connector 10, the connected object 60 can move within a predetermined range along at least one of the six directions: up, down, front, back, left, and right. However, it is not limited to this, and the connected object 60 may also be able to move within a predetermined range in diagonal directions between each of the six directions, in addition to the six directions: up, down, front, back, left, and right. 【0028】Figure 3 is an external perspective view of the connector 10 shown in Figure 1, viewed from above. Figure 4A is an exploded perspective view of the connector 10 in Figure 3, viewed from above. Figure 4B is an enlarged view of only the pair of contact modules 15 shown in Figure 4A. Figure 5 is a cross-sectional view along the line V-V in Figure 3. 【0029】 As can be seen from Figures 4A and 4B, the connector 10 is assembled in the following way, for example: Multiple contact modules 15, each having a first fixing portion 20a and a second fixing portion 20b integrally molded for each of the multiple contacts 30, are arranged in the second array direction. The connector 10 has multiple contact modules 15. The multiple contact modules 15 are arranged in the second array direction which intersects the first array direction. 【0030】 Multiple first fixing brackets 50a are press-fitted into the second fixing part 20b. The contact module 15, with the multiple first fixing brackets 50a press-fitted into the second fixing part 20b, is attached to the movable insulator 40 from below. This positions the contacts 30 relative to the movable insulator 40. The first fixing brackets 50a are press-fitted into the movable insulator 40 from below. The second fixing brackets 50b are attached to the multiple contact modules 15 attached to the movable insulator 40 from above. 【0031】 As described above, the contact 30 is held by the first fixing portion 20a and the second fixing portion 20b and positioned on the movable insulator 40. The movable insulator 40 is attached to the end of the contact module 15 on the side of the second fixing portion 20b and is movable relative to the first fixing portion 20a. At this time, the movable insulator 40 is movable integrally with the second fixing portion 20b, with the second fixing portion 20b fixed to the movable insulator 40 by the first fixing fitting 50a. 【0032】The following will mainly describe the configuration of each component of the connector 10 in the non-mated state. The configuration of the contact module 15 will be mainly described with reference to Figures 4A, 4B, and 5. The contact module 15 has a plurality of contacts 30 and a first fixing portion 20a and a second fixing portion 20b which are integrally molded with each of the plurality of contacts 30. 【0033】 As shown in Figures 4A and 4B, the first fixing portion 20a, which is integrally molded with the contact 30, is a member extending in the left-right direction, for example, by injection molding of an insulating and heat-resistant synthetic resin material. The first fixing portion 20a is integrally molded with the contact 30 by, for example, insert molding. The first fixing portion 20a is positioned to include the entire left-right region in which the plurality of contacts 30 are arranged. The first fixing portion 20a is integrally molded continuously in the left-right direction for all of the plurality of contacts 30. 【0034】 The first fixing portion 20a has mounting grooves 21a located on each side of the left-right region where the multiple contacts 30 are arranged. The mounting grooves 21a are recessed at two locations on both the left and right ends of the first fixing portion 20a, which extends in the longitudinal direction of the connector 10. The second fixing bracket 50b is attached to the mounting grooves 21a. 【0035】 The first fixing portion 20a is positioned at approximately the same left-right position as the mounting groove 21a and has a connecting portion 22a that protrudes one step inward in the front-rear direction from the mounting groove 21a. The connecting portion 22a protrudes from two locations at both ends in the left-right direction of the first fixing portion 20a which extends in the longitudinal direction of the connector 10. The two connecting portions 22a protruding from each other have different structures. For example, the connecting portion 22a located on one side in the left-right direction of the first fixing portion 20a has a recess. The connecting portion 22a located on the other side in the left-right direction of the first fixing portion 20a has a convex portion. 【0036】The second fixing portion 20b, which is integrally molded with the contact 30, is a member extending in the left-right direction, for example, by injection molding of an insulating and heat-resistant synthetic resin material. The second fixing portion 20b is integrally molded with the contact 30 by, for example, insert molding. The second fixing portion 20b is positioned to include the entire left-right region in which the plurality of contacts 30 are arranged. The second fixing portion 20b is integrally molded continuously in the left-right direction for all of the plurality of contacts 30. The second fixing portion 20b is, for example, a different member from the movable insulator 40. The second fixing portion 20b is not a part of the movable insulator 40, but is configured as a separate member separated from the movable insulator 40. 【0037】 The second fixing portion 20b has a plurality of mounting grooves 21b located in the left-right region where the plurality of contacts 30 are arranged. The plurality of mounting grooves 21b are arranged in the left-right direction in the second fixing portion 20b that extends in the longitudinal direction of the connector 10. The plurality of mounting grooves 21b are located inward in the front-rear direction from the plurality of contacts 30. The first fixing bracket 50a is attached to the mounting grooves 21b. 【0038】 As shown in Figures 4A, 4B, and 5, the contact 30 is formed from a thin sheet of copper alloy or Corson-type copper alloy containing, for example, pure copper, phosphor bronze, beryllium copper, or titanium copper, which has spring elasticity, using a progressive die (stamping) to form the shape shown in the figures. The contact 30 is manufactured by a process of bending in the thickness direction after punching. The manufacturing method of the contact 30 is not limited to this and may include only the punching process. The contact 30 may also be constructed flat without bending in the thickness direction. 【0039】 The contact 30 is made of a metal material with a low elastic modulus, for example, so that its shape changes due to elastic deformation are large. The surface of the contact 30 is plated with gold or tin after a nickel plating base coat has been created. 【0040】Multiple contacts 30 are arranged along the longitudinal direction of the connector 10. Each of the multiple contacts 30, made of metal, is arranged in a first arrangement direction. The same sets of contacts 30 arranged along the left-right direction in one of the front-to-back directions are also arranged symmetrically in the other of the front-to-back directions. The contacts 30 are used as signal terminals, for example. 【0041】 The contact 30 has a mounting portion 31 that extends outward in the front-rear direction in an L-shape at its lower end. The contact 30 has a first retained portion 32 that is positioned adjacent to and directly above the mounting portion 31 and is integrally molded with the first fixed portion 20a. The contact 30 has an elastic portion 33 that bends in an S-shape from the upper end of the first retained portion 32 and extends inward upward and in the front-rear direction. 【0042】 The contact 30 has a second retained portion 34 positioned adjacent to and directly above the elastic portion 33, and integrally molded with the second fixed portion 20b. The contact 30 has a connecting portion 35 that extends upward from the second retained portion 34, bends diagonally outward in the front-rear direction, and extends upward again. The contact 30 has an elastic contact piece 36 that extends upward from the upper end of the connecting portion 35, slightly inclined diagonally inward in the front-rear direction. 【0043】 The configuration of the movable insulator 40 will be mainly described with reference to Figures 4A and 5. The lower half of the movable insulator 40 is located in an internal space surrounded by a pair of contact modules 15 in the vertical region where the first fixing portion 20a and the second fixing portion 20b are located. The upper half of the movable insulator 40 is located above the internal space surrounded by the pair of contact modules 15 and is exposed. The upper half of the movable insulator 40 is located directly above the second fixing portion 20b. The movable insulator 40 is fitted with the object to be connected 60. 【0044】The movable insulator 40 is, for example, a member extending in the left - right direction, formed by injection - molding an insulating and heat - resistant synthetic resin material. The movable insulator 40 is configured in an inverted T - shape when viewed from the front in the front - to - back direction. The movable insulator 40 has a base portion 41 extending in the left - right direction in the lower half. The movable insulator 40 has a wall portion 41a disposed in a width - narrowed manner in the front - to - back direction at the base portion 41. The wall portion 41a is disposed over the entire vertical direction at the base portion 41. The wall portion 41a is disposed over substantially the entire left - right direction excluding the left and right end portions of the base portion 41. As also shown in FIG. 5, the wall portion 41a is disposed on a rectangle in a cross - sectional view and has a uniform front - to - back width along the vertical direction. 【0045】 As shown in FIG. 4A, the movable insulator 40 has retaining projections 42 projecting outward in the left - right direction on both left and right sides of the lower end portion of the base portion 41. The movable insulator 40 has a fitting convex portion 43 projecting upward from the base portion 41 and fitting with the connection object 60. The movable insulator 40 has a fitting concave portion 44 recessed on the upper surface of the fitting convex portion 43. 【0046】 The movable insulator 40 has a plurality of grooves 45 recessed on the inner surface in the front - to - back direction of the fitting concave portion 44 and extending over substantially the entire vertical direction in the fitting convex portion 43. A plurality of contacts 30 are respectively disposed in the plurality of grooves 45. The plurality of grooves 45 are recessed side - by - side at a predetermined interval from each other along the left - right direction. As also shown in FIG. 5, the grooves 45 are recessed on the inner surface in the front - to - back direction of the fitting convex portion 43 from the lower part to the upper part of the fitting convex portion 43. The lower end of the fitting convex portion 43 where the lower end of the groove 45 is located is vertically adjacent to the second fixing portion 20b. 【0047】Referring to FIG. 4A, the configuration of the first fixing fitting 50a will be mainly described. The first fixing fitting 50a is formed by shaping a thin plate of an arbitrary metal material into the shape shown in FIG. 4A using a progressive die (stamping). The processing method of the first fixing fitting 50a includes a process of bending in the plate thickness direction after punching. The first fixing fitting 50a is an L-shaped member. The processing method of the first fixing fitting 50a is not limited to this, and may include only the punching process. The first fixing fitting 50a may be configured flat without bending in the plate thickness direction. 【0048】 The first fixing fitting 50a has a base portion 51a that extends wide in the left-right direction in the first fixing fitting 50a. The first fixing fitting 50a has a first held portion 52a that extends outward in the front-rear direction in an L-shape from the lower end of the central portion in the left-right direction of the base portion 51a. The first fixing fitting 50a has a second held portion 53a that extends linearly upward from the upper end of the central portion in the left-right direction of the base portion 51a. 【0049】 Referring to FIG. 4A, the configuration of the second fixing fitting 50b will be mainly described. The second fixing fitting 50b is formed by shaping a thin plate of an arbitrary metal material into the shape shown in FIG. 4A using a progressive die (stamping). The processing method of the second fixing fitting 50b includes a process of bending in the plate thickness direction after punching. The second fixing fitting 50b is a U-shaped member. The processing method of the second fixing fitting 50b is not limited to this, and may include only the punching process. The second fixing fitting 50b may be configured flat without bending in the plate thickness direction. 【0050】 The second fixing fitting 50b has a mounting portion 51b that extends outward in the front-rear direction linearly at the lower end of the second fixing fitting 50b. The second fixing fitting 50b has a base portion 52b that is disposed directly above the pair of mounting portions 51b and connects the pair of mounting portions 51b in a U-shaped manner in the front-rear direction. The second fixing fitting 50b has a retaining portion 53b that bends inward in the left-right direction from the central portion in the front-rear direction and extends linearly at the upper edge portion of the base portion 52b. 【0051】As shown in Figures 4B and 5, the elastic portion 33 of the contact 30 is located in the region between the first fixing portion 20a and the second fixing portion 20b where only the contact 30 is positioned. The elastic portion 33 is positioned between the first fixing portion 20a and the second fixing portion 20b in the fitting direction. The elastic portion 33 is positioned in a region where none of the resin materials of the first fixing portion 20a, the second fixing portion 20b, or the movable insulator 40 are interposed. The elastic portion 33 includes the entire portion of the contact 30 located between the first fixing portion 20a and the second fixing portion 20b where no resin material is positioned on either of the pair of first surfaces S1 or the pair of second surfaces S2 of the contact 30. 【0052】 In this disclosure, “first surface S1” includes, for example, a surface that intersects the thickness direction of the contact 30. “Second surface S2” includes, for example, a surface that aligns with the thickness direction of the contact 30. The first surface S1 and the second surface S2 intersect each other. For example, the first surface and the second surface S2 are orthogonal to each other. 【0053】 The thickness direction of the contact 30 is any direction perpendicular to the left-right direction and is contained within a plane that extends up, down, front, and back as shown in Figure 5. The thickness of the contact 30 is substantially uniform at any point on the contact 30. As shown in Figure 4B, the width direction of the contact 30 is along the longitudinal direction of the connector 10. For example, the width direction of the contact 30 is the left-right direction. The width direction of the contact 30 is parallel to the first arrangement direction of the multiple contacts 30. 【0054】As shown in Figures 4B and 5, the elastic portion 33 of the contact 30 bends, for example, in the thickness direction. The elastic portion 33 has, for example, a plurality of bent portions. For example, the elastic portion 33 has two bent portions. For example, the elastic portion 33 has a first bent portion 33a located in a portion extending linearly upward from the upper end of the first held portion 32, which bends at an acute angle diagonally downward toward the inside in the front-rear direction. The elastic portion 33 has a second bent portion 33b located in a portion extending linearly diagonally downward from the first bent portion 33a, which bends at an acute angle upward. The elastic portion 33 achieves a three-dimensional structure by having a plurality of bent portions. The elastic portion 33 constitutes the entire contact 30 three-dimensionally. The bent portions of the elastic portion 33 elastically deform in a direction intersecting the first alignment direction, for example, in the second alignment direction. 【0055】 The first fixing portion 20a is positioned on a pair of opposing first surfaces S1 of the contact 30, starting from one end of the elastic portion 33 of the contact 30 that is opposite to the movable insulator 40. One end of the elastic portion 33 is the fitting end in the fitting direction and is the portion adjacent to the first fixing portion 20a directly above it. The first fixing portion 20a is positioned continuously on the pair of first surfaces S1 from one end of the elastic portion 33 toward the fitting side. 【0056】 The first fixing portion 20a is positioned at the same vertical position and with the same vertical width on a pair of first surfaces S1 that are opposite each other. The first fixing portion 20a covers the same region in the fitting direction that is covered with resin on one of the pair of first surfaces S1 with resin on the other surface as well. Unlike conventional configurations in which one of the surfaces is exposed and not covered with resin, the first fixing portion 20a symmetrically covers both of the pair of first surfaces S1 of the contact 30, reducing the exposed portion on one surface. 【0057】The first fixing portion 20a connects the plurality of contacts 30 along the first arrangement direction. The first fixing portion 20a is arranged continuously in the first arrangement direction as well as the fitting direction. The first fixing portion 20a is arranged on each of the pair of first surfaces S1 such that it has a first width in the fitting direction and a second width in the first arrangement direction. The first width corresponds, for example, to the vertical width of the first retained portion 32 located between the upper end of the mounting portion 31 of the contact 30 and one end of the elastic portion 33. The second width corresponds to a width that includes, for example, the entire region in the first arrangement direction in which the plurality of contacts 30 are arranged, and is larger than the entire region. 【0058】 The first fixing portion 20a is positioned on a pair of second surfaces S2 of the contact 30 that intersect the pair of first surfaces S1, and is continuously positioned along the entire circumference of the contact 30. The first fixing portion 20a is continuously positioned in the second alignment direction in addition to the fitting direction and the first alignment direction. The first fixing portion 20a is positioned on each of the pair of second surfaces S2 such that it also has a third width in the second alignment direction. The third width corresponds to a width that includes, for example, the entire thickness of the contact 30 and is greater than the entire thickness. Unlike conventional configurations in which one of the pair of first surfaces S1 and the pair of second surfaces S2 is exposed without being covered with resin, the first fixing portion 20a symmetrically covers all of the pair of first surfaces S1 and the pair of second surfaces S2 of the contact 30, thereby reducing the exposed portion on any of the surfaces. 【0059】 The second fixing portion 20b is positioned on a pair of first surfaces S1 extending from the other end of the elastic portion 33 of the contact 30. The other end of the elastic portion 33 is located on the same side as the movable insulator 40, and is the end on the withdrawal side in the fitting direction, and is the adjacent portion directly below the second fixing portion 20b. The second fixing portion 20b is continuously positioned on a pair of first surfaces S1 extending from the other end of the elastic portion 33 toward the withdrawal side. 【0060】The second fixing portion 20b is positioned at the same vertical position and with the same vertical width on the pair of first surfaces S1, facing each other. The second fixing portion 20b covers the same region in the fitting direction that is covered with resin on one of the pair of first surfaces S1 with resin on the other surface as well. Unlike conventional configurations in which one of the surfaces is exposed and not covered with resin, the second fixing portion 20b symmetrically covers both of the pair of first surfaces S1 of the contact 30, reducing the exposed portion on one surface. 【0061】 The second fixing portion 20b connects the plurality of contacts 30 along the first alignment direction. The second fixing portion 20b is arranged continuously in the first alignment direction as well as the fitting direction. The second fixing portion 20b is arranged on each of the pair of first surfaces S1 such that it has a fourth width in the fitting direction and a fifth width in the first alignment direction. The fourth width corresponds, for example, to the vertical width of the second retained portion 34 located between the other end of the elastic portion 33 and the lower end of the connecting portion 35. The fifth width corresponds to a width that includes, for example, the entire region in the first alignment direction in which the plurality of contacts 30 are arranged, and is larger than the entire region. 【0062】 The second fixing portion 20b is positioned on a pair of second surfaces S2 of the contact 30 that intersect the pair of first surfaces S1, and is continuously positioned along the entire circumference of the contact 30. The second fixing portion 20b is continuously positioned in the second alignment direction, in addition to the fitting direction and the first alignment direction. The second fixing portion 20b is positioned on each of the pair of second surfaces S2 such that it also has a sixth width in the second alignment direction. The sixth width corresponds to a width that includes, for example, the entire thickness of the contact 30 and is greater than the entire thickness. Unlike conventional configurations in which one of the pair of first surfaces S1 and the pair of second surfaces S2 is exposed without being covered with resin, the second fixing portion 20b symmetrically covers all of the pair of first surfaces S1 and the pair of second surfaces S2 of the contact 30, thereby reducing the exposed portion on any of the surfaces. 【0063】As shown in Figure 5, the connecting portion 35 of the contact 30 is located inside the groove 45 that extends to the fitting projection 43 of the movable insulator 40. At this time, the connecting portion 35 is not attached to the movable insulator 40. The movable insulator 40 is not held by the contact 30, but is held by the contact module 15 via the first fixing bracket 50a, as will be described later. The movable insulator 40 is fixed to the contact module 15 by the first fixing bracket 50a. The contact 30 does not have any other mounting structures such as other held portions or locking portions other than the first held portion 32 and the second held portion 34. 【0064】 The mounting portion 31 of the contact 30 is located on the opposite side of the elastic portion 33 from the first fixed portion 20a. The mounting portion 31 is mounted on the circuit board CB1, as will be described later. The elastic contact piece 36, which is the contact portion of the contact 30, is located on the opposite side of the elastic portion 33 from the second fixed portion 20b and is positioned relative to the movable insulator 40. 【0065】 When each of the multiple contacts 30 is positioned relative to the movable insulator 40, the elastic portion 33 of the contact 30 is positioned between the first fixed portion 20a, which acts as a fixed insulator, and the movable insulator 40 in the fitting direction. The elastic contact piece 36 is positioned along the groove 45 of the fitting projection 43 of the movable insulator 40. The inner end of the elastic contact piece 36 in the front-rear direction is exposed inward from the groove 45 in the front-rear direction and is positioned inside the fitting recess 44 of the movable insulator 40. The elastic contact piece 36 is elastically deformable along the front-rear direction inside the groove 45. 【0066】The first retained portion 52a of the first fixing bracket 50a engages with the mounting groove 21b of the second fixing portion 20b. The first retained portion 52a is attached to the second fixing portion 20b. Similarly, the second retained portion 53a of the first fixing bracket 50a engages with the mounting groove 43a recessed in the lower surface of the fitting projection 43 of the movable insulator 40. The second retained portion 53a is attached to the movable insulator 40. The movable insulator 40 is attached to the second fixing portion 20b. For example, the movable insulator 40 is attached to the second fixing portion 20b via the first fixing bracket 50a and is fixed to the second fixing portion 20b. 【0067】 When each of the multiple first fixing brackets 50a is attached to the second fixing part 20b and the movable insulator 40, the movable insulator 40 is attached to the second fixing part 20b via the multiple first fixing brackets 50a. The first fixing brackets 50a are attached to the second fixing part 20b and the movable insulator 40 to fix them together. The second fixing part 20b is located on the movable insulator 40 side. The second fixing part 20b is located directly below the fitting projection 43 of the movable insulator 40 and is integrally positioned with the movable insulator 40 via the first fixing brackets 50a. 【0068】 As described above, the connecting portion 35 of each contact 30 is positioned in the groove 45 of the movable insulator 40. The second retained portion 53a of each first fixing bracket 50a is attached to the mounting groove 43a of the movable insulator 40. In this way, the movable insulator 40 is attached to the contact module 15. 【0069】 At this time, the movable insulator 40 is supported by the contact module 15 in a state where it is integrally positioned with the second fixed part 20b, separated from the first fixed part 20a which acts as a fixed insulator, and floating. The movable insulator 40 and the second fixed part 20b move integrally with each other relative to the first fixed part 20a during the floating operation of the connector 10. The mating projection 43 and mating recess 44 of the movable insulator 40 are positioned above the second fixed part 20b in a state where they can be mated with the insulator 70 of the object to be connected 60. 【0070】As can be seen from Figures 3 and 4A, the base 52b of the second fixing bracket 50b engages with the mounting groove 21a of the first fixing portion 20a of each of the pair of contact modules 15. The base 52b is attached to the pair of first fixing portions 20a. 【0071】 When the second fixing bracket 50b is attached to the pair of first fixing parts 20a, the recess of the connecting part 22a located on one of the pair of first fixing parts 20a engages with the protrusion of the connecting part 22a located on the other. Similarly, the protrusion of the connecting part 22a located on one of the pair of first fixing parts 20a engages with the recess of the connecting part 22a located on the other. As a result, the pair of contact modules 15 are connected to each other via the pair of first fixing parts 20a. The second fixing bracket 50b fixes the multiple contact modules 15 in the second arrangement direction. 【0072】 The second fixing bracket 50b fixes the first fixing portion 20a of the multiple contact modules 15 in the second array direction, and positions the first fixing portion 20a and the movable insulator 40 relative to the circuit board CB1. At this time, the connector 10 has pairs of identical contact modules 15 facing each other in the second array direction. The contacts 30 on one side and the contacts 30 on the other side in the second array direction are arranged symmetrically along the line in the second array direction. 【0073】 When the second fixing bracket 50b is attached to the pair of first fixing parts 20a, the retaining portion 53b of the second fixing bracket 50b is positioned directly above the retaining projection 42 of the movable insulator 40 and spaced apart from the retaining projection 42 in the fitting direction. The retaining projection 42 of the movable insulator 40 is positioned spaced apart from the first fixing parts 20a and floating in the internal space surrounded by the first fixing parts 20a. The lower surface and both front-rear sides of the retaining projection 42 of the movable insulator 40 are spaced apart from the first fixing parts 20a. The upper surface of the retaining projection 42 faces the retaining portion 53b, spaced apart in the vertical direction. The second fixing bracket 50b contributes to preventing the movable insulator 40 from coming off in the fitting direction when the movable insulator 40 and the object to be connected 60 are fitted together. The retaining portion 53b of the second fixing bracket 50b is configured to have multiple contact modules 15 and movable insulators 40 positioned on the fitting side in the fitting direction. 【0074】 The connector 10 having the structure described above is mounted, for example, on the circuit surface located on the mounting surface of the circuit board CB1, as shown in Figure 3. More specifically, the mounting portion 31 of the contact 30 is placed on solder paste applied to the signal pattern on the circuit board CB1. The mounting portion 51b of the second fixing bracket 50b is placed on solder paste applied to the ground pattern on the circuit board CB1. 【0075】 By heating and melting each solder paste in a reflow oven or the like, the mounting portion 31 and mounting portion 51b are soldered to the signal pattern and ground pattern, respectively. As a result, the mounting of the connector 10 to the circuit board CB1 is completed. Other electronic components, such as a CPU (Central Processing Unit), controller, or memory, are mounted on the circuit side of the circuit board CB1. 【0076】 The structure of the object to be connected, 60, will be explained mainly with reference to Figures 6 and 7. 【0077】 Figure 6 is an external perspective view showing the object to be connected 60, which is connected to the connector 10 in Figure 3, from a top view. Figure 7 is an exploded perspective view of the object to be connected 60 in Figure 6, also from a top view. The object to be connected 60 is assembled, for example, by press-fitting the contact 80 and the metal member 90 into the insulator 70 from below. 【0078】 The insulator 70 is, for example, a rectangular prism-shaped member made by injection molding of an insulating and heat-resistant synthetic resin material. The insulator 70 includes four side walls on the front, back, left, and right sides, and has an outer peripheral wall 71 surrounding its interior. More specifically, the outer peripheral wall 71 includes short walls 71a on both the left and right sides and long walls 71b on both the front and rear sides. The insulator 70 has a fitting recess 72 at its upper part, surrounded on the outside in the front, back, left, and right directions by the outer peripheral wall 71. The insulator 70 has a fitting projection 73 that protrudes upward at the center of the fitting recess 72 in the front, back, left, and right directions. 【0079】The insulator 70 has a first mounting groove 74 recessed in the vertical direction from the outer surface of the fitting projection 73 in the front-rear direction to the inner surface of the longitudinal wall 71b. Multiple first mounting grooves 74 are arranged in the left-right direction. The contact 80 is mounted in the first mounting groove 74. The insulator 70 has a second mounting groove 75 recessed in each of the four corners of the bottom of the outer peripheral wall 71. The metal member 90 is mounted in the second mounting groove 75. 【0080】 The contact 80 is formed from a thin sheet of copper alloy or Corson-type copper alloy containing pure copper, phosphor bronze, beryllium copper, or titanium copper, which has spring elasticity, using a progressive die (stamping) to form the shape shown in Figure 7. The contact 80 is manufactured by a process of bending the sheet in the thickness direction after punching. The manufacturing method of the contact 80 is not limited to this and may include only the punching process. The contact 80 may also be constructed flat without bending in the thickness direction. The surface of the contact 80 is plated with gold or tin after creating a base layer with nickel plating. 【0081】 Multiple contacts 80 are arranged along the longitudinal direction of the connector 10. The same sets of contacts 80 that are arranged along the left-right direction in one of the front-to-back directions are also arranged symmetrically in the other of the front-to-back directions. 【0082】 The contact 80 has a mounting portion 81 that extends outward in an L-shape in the front-rear direction at the lower end of the contact 80. The contact 80 has a first retained portion 82 that extends upward from the upper end of the mounting portion 81. The first retained portion 82 includes a portion that is wider in the left-right direction compared to other parts of the contact 80 located around the first retained portion 82. The contact 80 has a connecting portion 83 that extends diagonally upward inward in the front-rear direction from the upper end of the first retained portion 82 and extends upward in an L-shape. 【0083】The contact 80 has a second retained portion 84 that extends linearly upward from the inner end in the front-rear direction of the connecting portion 83. The second retained portion 84 includes a portion that is wider in the left-right direction compared to other parts of the contact 80 located around the second retained portion 84. The contact 80 has a contact portion 85 that extends linearly upward from the upper end of the second retained portion 84. The contact 80 is used as a signal terminal, for example. 【0084】 The metal member 90 is formed from a thin sheet of any metal material using a progressive die (stamping) to the shape shown in Figure 7. The processing method for the metal member 90 includes a step of bending the sheet in the thickness direction after punching. The metal member 90 is an L-shaped member. The processing method for the metal member 90 is not limited to this and may include only the punching step. The metal member 90 may also be constructed flat without bending in the thickness direction. 【0085】 The metal member 90 has a base portion 91 that extends broadly in the vertical, horizontal, and vertical directions. The metal member 90 has a mounting portion 92 that extends outward in the front-rear direction in an L-shape from the lower end of the central part of the base portion 91 in the horizontal direction. The metal member 90 has a holding portion 93 that is positioned at both ends of the base portion 91 in the horizontal direction. 【0086】 The first retained portion 82 and the second retained portion 84 of the contact 80 engage with the first mounting groove 74 of the insulator 70. The contact 80 is attached to the insulator 70 via the first retained portion 82 and the second retained portion 84. When each of the multiple contacts 80 is attached to the insulator 70, the contact portion 85 of the contact 80 is located in the portion of the first mounting groove 74 of the insulator 70 that is recessed on the outer surface in the front-rear direction of the fitting projection 73. 【0087】 The retained portion 93 of the metal member 90 is locked into the second mounting groove 75 of the insulator 70. The metal member 90 is attached to the insulator 70 via the retained portion 93. The four metal members 90 are attached to the four corners of the bottom of the insulator 70. 【0088】The object to be connected, 60, with the structure described above, is mounted on the circuit surface located on the mounting surface of the circuit board CB2, as shown in Figure 6. More specifically, the mounting portion 81 of the contact 80 is placed on solder paste applied to the signal pattern on the circuit board CB2. The mounting portion 92 of the metal member 90 is placed on solder paste applied to the ground pattern on the circuit board CB2. 【0089】 By heating and melting each solder paste in a reflow oven or the like, the mounting parts 81 and 92 are soldered to the signal pattern and ground pattern, respectively. As a result, the mounting of the connection target 60 to the circuit board CB2 is completed. On the circuit side of the circuit board CB2, electronic components other than the connection target 60, such as a camera module or a sensor, are mounted. 【0090】 The operation of the floating connector 10 will be described primarily. 【0091】 The mounting portion 31 of the contact 30 and the mounting portion 51b of the second fixing bracket 50b are soldered to the circuit board CB1, thereby fixing the first fixing portion 20a, which acts as a fixing insulator, to the circuit board CB1. The movable insulator 40 and the second fixing portion 20b become movable relative to the first fixing portion 20a fixed to the circuit board CB1 as the contact 30 undergoes elastic deformation. For example, the movable insulator 40 and the second fixing portion 20b are movable in the front-to-back direction as the contact 30 undergoes elastic deformation in the front-to-back direction. The movable insulator 40 and the second fixing portion 20b are also movable in the left-to-right direction as the contact 30 undergoes elastic deformation in the left-to-right direction. 【0092】 With respect to the floating structure of the connector 10 as described above, the object to be connected 60 is positioned so that its front-to-back and left-to-right positions are approximately aligned with the connector 10, and then the object to be connected 60 is positioned facing it in the vertical direction. After that, the object to be connected 60 is moved downward. At this time, even if their positions are slightly misaligned in the front-to-back and left-to-right directions, the object to be connected 60 will be attracted to the connector 10. 【0093】At this time, the floating structure of the connector 10 causes the movable insulator 40 to move relative to the first fixed part 20a. More specifically, the fitting projection 43 of the movable insulator 40 is drawn into the fitting recess 72 of the insulator 70. When the object to be connected 60 is moved downward, the fitting recess 44 of the movable insulator 40 and the fitting projection 73 of the insulator 70 engage with each other. 【0094】 Figure 8 is a cross-sectional view taken along the line VIII-VIII in Figure 1. 【0095】 As shown in Figure 8, in the mated state in which the movable insulator 40 of the connector 10 and the insulator 70 of the object to be connected 60 are fitted together, the contact 30 of the connector 10 and the contact 80 of the object to be connected 60 are in contact with each other. For example, the elastic contact piece 36 of the contact 30 and the contact portion 85 of the contact 80 are in contact with each other. At this time, the elastic contact piece 36 of the contact 30 is slightly elastically deformed outward in the front-rear direction and is elastically displaced outward in the front-rear direction inside the groove 45. 【0096】 As a result, the connector 10 and the object to be connected 60 are fully connected. At this time, circuit boards CB1 and CB2 are electrically connected to each other via the connector 10 and the object to be connected 60. For example, an electrical signal flows between circuit boards CB1 and CB2 via contacts 30 and 80. 【0097】 The following explanation will primarily focus on the connector 10 and its effects, but the same explanation applies to electronic devices that have the connector 10. 【0098】According to the connector 10 of the above embodiment, the robustness of the connector 10 during floating movement is improved. In the connector 10, the first fixing portion 20a is arranged on a pair of first surfaces S1 from one end of the elastic portion 33 and connects a plurality of contacts 30 along the first arrangement direction. The second fixing portion 20b is arranged on a pair of first surfaces S1 from the other end of the elastic portion 33 and connects a plurality of contacts 30 along the first arrangement direction. As a result, the connector 10 can improve the holding force or fixing force of the contacts 30 used for floating movement in the connector 10. 【0099】 The connector 10 integrally molds a first fixing portion 20a and a second fixing portion 20b at both ends of the elastic portion 33 of the contact 30, thereby connecting and fixing multiple contacts 30 in a first arrangement direction. As a result, the connector 10 does not need to increase the length and width of the locking portion compared to conventional floating connectors in which each contact is press-fitted into the insulators on the movable and fixed sides. The connector 10 can improve the holding or fixing force of the contact 30 to the resin part without increasing the length and width of the locking portion. 【0100】 In conventional floating connectors, the impedance decreases due to the large length and width of the contact locking portion. In addition, conventional floating connectors have structural constraints that prevent the plate width from being larger in parts of the contact other than the locking portion. In conventional floating connectors, these factors limit the impedance adjustment at the locking portion. Connector 10 according to one embodiment alleviates the structural constraints that have been a problem in conventional floating connectors. Therefore, connector 10 can further reduce impedance mismatch. 【0101】The connector 10 can also be configured such that, in each of the first fixing portion 20a and the second fixing portion 20b, there are no portions on a pair of first surfaces S1 adjacent to the elastic portion 33 where resin is placed on one side and not on the other side, leaving it exposed. This reduces the amount of exposed portions on one side of the contact 30 where resin is not placed. Therefore, the connector 10 can reduce the possibility of the contact 30 peeling off from the exposed portion during floating movement, which could lead to damage to the first fixing portion 20a or the second fixing portion 20b. The above differs from conventional floating connectors manufactured by insert molding. 【0102】 The elastic portion 33 of the contact 30 is located between the first fixing portion 20a and the second fixing portion 20b and has a bent portion. The bent portion elastically deforms, for example, in a direction intersecting the first alignment direction. As a result, the contact 30 can have a three-dimensional structure formed by press working such as bending as a floating spring structure. This makes it possible for the connector 10 to have improved floating mobility compared to conventional floating connectors that have a planar floating spring structure formed by, for example, only a punching process. Unlike conventional floating connectors in which the bent portion of the floating spring is not arranged in the plate thickness direction, for example, the connector 10 can achieve floating motion in three dimensions. The connector 10 can also improve the amount of movement of the movable insulator 40 during floating motion. 【0103】 At least one of the first fixing portion 20a and the second fixing portion 20b is positioned on a pair of second surfaces S2 of the contact 30 that intersect a pair of first surfaces S1, and is continuously positioned along the entire circumference of the contact 30. This makes it possible for the connector 10 to improve the holding or fixing force of the contact 30 used for floating movement in the connector 10. Therefore, it is possible to improve the robustness of the connector 10 when it is floating. 【0104】The second fixing portion 20b is a different component from the movable insulator 40. This allows the connector 10 to configure the contact module 15 independently of the movable insulator 40. Therefore, the connector 10 can improve the design flexibility of the contact module 15. 【0105】 The connector 10 has a second fixing part 20b and a first fixing bracket 50a that is attached to the movable insulator 40 and fixes them together. The movable insulator 40 is attached to the second fixing part 20b via the first fixing bracket 50a and is fixed to the second fixing part 20b. As a result, the connector 10 can easily attach the second fixing part 20b to the movable insulator 40 via the first fixing bracket 50a. Therefore, the connector 10 can easily attach the contact module 15 having the second fixing part 20b to the movable insulator 40. The connector 10 can achieve stable floating operation by realizing the movement of the second fixing part 20b in conjunction with the movable insulator 40. 【0106】 In connector 10, multiple contact modules 15 are arranged in a second array direction that intersects the first array direction. In this way, connector 10 makes it possible to arrange multiple contact modules 15 in a state where they are separated from each other along the second array direction. Connector 10 makes it possible to design the type of contact module 15 for each module. In addition, connector 10 makes it possible to easily change the number of contact modules 15. As a result, connector 10 can also improve the degree of freedom in designing the contact modules 15. 【0107】The connector 10 has a second fixing bracket 50b that fixes the first fixing portion 20a of the multiple contact modules 15 in the second arrangement direction, and positions the first fixing portion 20a and the movable insulator 40 relative to the circuit board CB1. As a result, the connector 10 can stably fix the multiple contact modules 15 that were arranged separately along the second arrangement direction. The connector 10 can also integrate the multiple contact modules 15 and configure the fixing insulator for the movable insulator 40 with a plurality of integrated first fixing portions 20a. The connector 10 can also float and move the multiple contact modules 15 as a single unit by attaching the multiple contact modules 15 to the movable insulator 40. 【0108】 The second fixing bracket 50b of the connector 10 contributes to preventing the movable insulator 40 from coming off in the mating direction. The retaining portion 53b of the second fixing bracket 50b arranges multiple contact modules 15 and the movable insulator 40 on the mating side in the mating direction. As a result, the connector 10 can reduce the likelihood of the movable insulator 40 coming off the integrated multiple contact modules 15 in the disengaging direction during floating operation. 【0109】 The connector 10 has a pair of identical contact modules 15 facing each other in the second array direction. The contacts 30 on one side and the contacts 30 on the other side in the second array direction are arranged symmetrically along the line in the second array direction. This makes it possible to assemble the connector 10 by simply manufacturing multiple single contact modules 15 having the same configuration as each other. Therefore, the assembly of the connector 10 becomes easy. 【0110】 Because the contact 30 is made of a metal material with a low elastic modulus, the connector 10 can ensure the required amount of movement of the movable insulator 40 even when the force applied to the movable insulator 40 is small. The movable insulator 40 can move smoothly relative to the first fixed part 20a. As a result, the connector 10 can easily absorb misalignment when mating with the object to be connected 60. 【0111】 The connector 10 absorbs vibrations caused by external factors through the elastic deformation of the contact 30. This reduces the possibility of large forces being applied to the mounting portion 31 of the contact 30. Therefore, damage to the connection portion with the circuit board CB1 is reduced. Cracks in the solder at the connection portion between the circuit board CB1 and the mounting portion 31 can be reduced. Therefore, connection reliability is improved even when the connector 10 and the object to be connected 60 are connected. 【0112】 It will be apparent to those skilled in the art that this disclosure can be implemented in other predetermined forms besides the embodiments described above without deviating from its spirit or essential features. Therefore, the prior description is illustrative and not limiting. The scope of the disclosure is defined not by the prior description but by the added claims. Any modifications within their equivalent scope are included therein. 【0113】 For example, the shape, pattern, size, arrangement, orientation, type, or number of each component described above are not limited to those shown in the above description and drawings. The shape, pattern, size, arrangement, orientation, type, or number of each component may be configured arbitrarily as long as it can achieve its function. Each component of the illustrated connector 10 and the object to be connected 60 is a functional concept. The specific form of each component is not limited to those shown. 【0114】 The assembly method of the connector 10 described in the above embodiment is not limited to the above description. The assembly method of the connector 10 may be any method as long as it can be assembled in a way that allows it to perform its function. 【0115】For example, the contact 30 may be attached to the movable insulator 40 by press-fitting, or it may be integrally molded with the movable insulator 40 by insert molding. The first fixing bracket 50a may be integrally molded with the movable insulator 40 by insert molding instead of press-fitting. The first fixing bracket 50a may be integrally molded with the second fixing part 20b by insert molding instead of press-fitting. The second fixing bracket 50b may be integrally molded with the first fixing part 20a by insert molding instead of press-fitting. 【0116】 The assembly method for the connection target 60 described in the above embodiment is not limited to the above description. The assembly method for the connection target 60 may be any method as long as it can be assembled in a way that allows it to perform its function. For example, at least one of the contact 80 and the metal member 90 may be integrally molded with the insulator 70 by insert molding rather than press fitting. 【0117】 In the above embodiment, it was described that each of the first fixing portion 20a and the second fixing portion 20b is arranged on a pair of second surfaces S2 and continuously along the entire circumference of the contact 30, but this is not limited to this. At least one of the first fixing portion 20a and the second fixing portion 20b does not have to be arranged on both of the pair of second surfaces S2, or it may be arranged on only one of the pair of second surfaces S2. Accordingly, at least one of the first fixing portion 20a and the second fixing portion 20b does not have to be continuously arranged along the entire circumference of the contact 30. 【0118】 In the above embodiment, the first surface S1 was described as including a surface that intersects the thickness direction of the contact 30, but it is not limited to this. The first surface S1 may include, for example, a surface that is aligned with the thickness direction of the contact 30. In this case, the second surface S2 may include, for example, a surface that intersects the thickness direction of the contact 30. 【0119】In the above embodiment, the second fixing portion 20b was described as being a different material from the movable insulator 40, but this is not limited to that. For example, the second fixing portion 20b may be the same material as the movable insulator 40. The second fixing portion 20b may constitute a part of the movable insulator 40. The second fixing portion 20b may be integrally configured with the movable insulator 40. 【0120】 In the above embodiment, the connector 10 was described as having a first fixing bracket 50a attached to the second fixing part 20b and the movable insulator 40 to fix them together, but it is not limited to this. The second fixing part 20b and the movable insulator 40 may be fixed to each other in a manner different from the method using the first fixing bracket 50a. For example, the second fixing part 20b and the movable insulator 40 may be fixed to each other by the fitting of interlocking protrusions and recesses arranged on their respective resins, or they may be fixed to each other by other resin members having a shape similar to the first fixing bracket 50a. In these cases, the connector 10 does not have to have the first fixing bracket 50a. Even in these cases, the movable insulator 40 may be attached to the second fixing part 20b. 【0121】 In the above embodiment, the connector 10 was described as having multiple contact modules 15, but it is not limited to this. The connector 10 may have only one contact module 15. The multiple contact modules 15 were described as being arranged in a second arrangement direction intersecting the first arrangement direction, but it is not limited to this. The multiple contact modules 15 may be arranged in a direction different from the second arrangement direction. For example, the multiple contact modules 15 may be arranged in series in the first arrangement direction rather than in parallel in the second arrangement direction. 【0122】In the above embodiment, the connector 10 is described as having a second fixing fitting 50b that fixes a plurality of contact modules 15 in a second arrangement direction and contributes to preventing the movable insulator 40 from coming loose in the mating direction, but it is not limited to this. The connector 10 does not have to have the second fixing fitting 50b. For example, the plurality of contact modules 15 may be fixed to each other only by the mating of resins via a connecting portion 22a, or they may be fixed to each other by other resin members having a shape similar to the second fixing fitting 50b. The prevention of the movable insulator 40 from coming loose in the mating direction may be achieved, for example, by a first fixing portion 20a instead of or in addition to the second fixing fitting 50b, or by other resin members having a shape similar to the second fixing fitting 50b. The second fixing fitting 50b does not have to have a retaining portion 53b. In this case, the second fixing fitting 50b may be press-fitted into the first fixing portion 20a from the mating side, rather than from the removal side. 【0123】 In the above embodiment, the elastic portion 33 that bends in the thickness direction of the contact 30 is described as having two bent portions, a first bent portion 33a and a second bent portion 33b, but it is not limited to this. The elastic portion 33 may have only one bent portion or three or more bent portions, as long as a three-dimensional structure can be realized. The contact 30 including the elastic portion 33 is not limited to the shape shown in Figure 5, etc., as long as it has a three-dimensional structure, and may have any other shape. 【0124】 In the above embodiment, the elastic portion 33 of the contact 30 was described as bending in the thickness direction, but is not limited to this. The elastic portion 33 may bend in a direction different from the thickness direction. The bent portion of the elastic portion 33 was described as elastically deforming in a direction intersecting the first alignment direction, but is not limited to this. The bent portion of the elastic portion 33 may elastically deform in a direction different from the direction intersecting the first alignment direction. 【0125】In the above embodiment, the contact 30 was described as having only one elastic portion 33, but it is not limited to this. The contact 30 may have multiple elastic portions 33. In this case, the contact module 15 may have fixing portions at both ends of each of the multiple elastic portions 33. For example, when the contact 30 has two elastic portions 33, the contact module 15 may have a third fixing portion in addition to the first fixing portion 20a and the second fixing portion 20b, which sandwiches the other elastic portion 33 together with the second fixing portion 20b. When the contact 30 has two elastic portions 33, the contact module 15 may have another pair of third and fourth fixing portions in addition to the first fixing portion 20a and the second fixing portion 20b, which sandwich the other elastic portion 33. 【0126】 In the above embodiment, the contact 30 was described as being made of a metallic material with a low elastic modulus, but this is not limited to that. The contact 30 may be made of a metallic material having any elastic modulus, as long as the required amount of elastic deformation can be secured. 【0127】 In the above embodiment, the object to be connected 60 was described as a plug connector connected to the circuit board CB2, but it is not limited to this. The object to be connected 60 may be any object other than a connector. For example, the object to be connected 60 may be an FPC, a flexible flat cable, a rigid substrate, or the card edge of any circuit board. 【0128】 Figure 9 is a cross-sectional view corresponding to Figure 8, showing a cross-section of the connector 10 according to a first modified example in which the object to be connected 60 is connected. 【0129】 In the above embodiment, the connector 10 was described as a receptacle connector and the object to be connected 60 as a plug connector, but the types of connector 10 and object to be connected 60 are not limited to these. For example, the connector 10 may function as a plug connector and the object to be connected 60 may function as a receptacle connector. 【0130】In the mated state, when the movable insulator 40 of the connector 10 and the insulator 70 of the object to be connected 60 are engaged with each other, the contact 30 of the connector 10 as a plug connector does not need to undergo elastic deformation. On the other hand, in the mated state, the contact 80 of the object to be connected 60 as a receptacle connector may undergo elastic deformation. 【0131】 Figure 10 is a perspective view of the connector 10 alone, corresponding to Figure 3, in a top view, showing the second modified example. Figure 11 is a perspective view of the connector 10 in Figure 10 when the movable insulator 40 is omitted. 【0132】 In the above embodiment, the type of contact 30 is the same in one of the pair of contact modules 15, but this is not limited to this. For example, the type of contact 30 may be different in one of the multiple contact modules 15. 【0133】 In the second modified example shown in Figures 10 and 11, one of the pair of contact modules 15 may have a first contact 30a. The first contact 30a may be used as a signal terminal, for example, similar to the contact 30 in the above embodiment. The other of the pair of contact modules 15 may have a second contact 30b. Unlike the contact 30 in the above embodiment, the second contact 30b may be used for purposes other than a signal terminal, for example. For example, the second contact 30b may be used as a power terminal or as a ground terminal. 【0134】 With the second modification described above, the connector 10 can arrange pairs of contact modules 15 having different functions relative to the movable insulator 40. The connector 10 can also integrate pairs of contact modules 15 having different functions with the movable insulator 40 to provide multiple functions with the connector 10 alone. For example, the connector 10 can provide both electrical signal transmission and power supply with the connector 10 alone. 【0135】Figure 12 is a perspective view of the connector 10 alone, corresponding to Figure 3, as seen from above. Figure 13 is a perspective view of the connector 10 according to the third modified example, with the movable insulator 40 of Figure 12 omitted. 【0136】 In the above embodiment, the connector 10 was described as having a pair of contact modules 15, but is not limited thereto. The connector 10 may have three or more contact modules 15. In the third modification shown in Figures 12 and 13, the connector 10 may have four contact modules 15 arranged in a second arrangement direction. The four contact modules 15 may be fixed in the second arrangement direction by a second fixing bracket 50b. The four contact modules 15 may be integrally attached to the movable insulator 40. 【0137】 The connector 10 described above is mounted on an electronic device. The electronic device includes, for example, any in-vehicle equipment such as cameras, radar, drive recorders, and engine control units. The electronic device also includes, for example, any in-vehicle equipment used in in-vehicle systems such as car navigation systems, advanced driver-assistance systems, and security systems. The electronic device also includes, for example, any information equipment such as personal computers, smartphones, copiers, printers, fax machines, and multifunction devices. In addition, the electronic device includes any industrial equipment. 【0138】 Such electronic devices, in connectors 10 with a floating structure, offer the effect of improving the robustness of the connector 10 when it is floating and moving. Therefore, the reliability of the electronic device having the connector 10 as a product is improved. 【0139】 The excellent floating structure of connector 10 absorbs misalignment between circuit boards, improving work efficiency when assembling electronic equipment. This makes the manufacturing of electronic equipment easier. The connector 10 reduces damage to the connection point with circuit board CB1, improving the reliability of the electronic equipment as a product. 【0140】Some embodiments of the present disclosure are described below.
