Description

[Technical field]

[0001] The present invention relates to a movable connector in which a shield is attached to a housing, and a method of manufacturing a shield that is attached to a housing of a movable connector. [Background technology]

[0002] The following Patent Document 1 discloses a movable connector. In this movable connector, a movable space is formed between a fixed housing and a movable housing. A terminal is bridged between the fixed housing and the movable housing, and a U-shaped movable spring part of the terminal is elastically deformed in the movable space. This allows the movable housing to be displaced relative to the fixed housing. In addition, this movable connector has a metal shell member (shield) attached to the fixed housing to provide noise countermeasures. This shield has a soldering part protruding in a direction along the plane of the board, and by soldering the soldering part to the board, the shield is electrically connected to the GND circuit of the board and the connector is prevented from peeling off from the board.

[0003] [Patent Document 1] JP 2013-45739 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, with the recent trend toward miniaturization of electronic devices, there is a demand for connectors mounted on boards to occupy a smaller area on the board. For this reason, with the above-mentioned movable connector, it is becoming difficult to simultaneously ensure the movable space of the movable housing and the size of the soldered part of the shield (i.e., the soldering strength of the soldered part to the board).

[0005] The present invention aims to provide a movable connector that can easily ensure both the movable space of the movable housing and the soldering strength of the shield, even when the area it occupies on the board is set small, and a manufacturing method for a shield that is suitable for manufacturing the shield of the movable connector. [Means for solving the problem]

[0006] The movable connector of the first aspect is a movable connector having a housing, a terminal held by the housing, and a shield attached to the housing, the housing having a first housing fixed to a board, and a second housing connected to the first housing via the terminal so as to be elastically displaceable, the first housing extending in a first direction along a plane of the board, and having a main body wall portion facing the second housing from the outside in a second direction along the plane and intersecting the first direction, and a shield attached to the main body wall portion. and an extension wall portion adjacent to the first direction, the shield has a shield main body wall portion covering the main body wall portion from the outside in the second direction, a shield extension wall portion arranged on the extension wall portion, and a shield connection portion connecting the shield main body wall portion and the shield extension wall portion, the shield extension wall portion having a base portion covering the extension wall portion from the outside in the second direction, and a soldering portion protruding from the base portion outward in the second direction and soldered to the board, and the shield main body wall portion is positioned outward in the second direction than the base.

[0007] In the movable connector of the first aspect, the housing in which the terminals are held and the shield is attached includes a first housing fixed to the board and a second housing elastically displaceably connected to the first housing via the terminals. The first housing extends in a first direction along the plane of the board and has a main body wall portion facing the second housing from the outside in a second direction along the plane of the board and intersecting the first direction, and an extension wall portion adjacent to the main body wall portion in the first direction. The shield has a shield main body wall portion covering the main body wall portion from the outside in the second direction (i.e., the opposite side to the second housing), a shield extension wall portion disposed on the extension wall portion, and a shield connection portion connecting the shield main body wall portion and the shield extension wall portion.

[0008] The above-mentioned shield extension wall has a base covering the extension wall of the first housing from the outside in the second direction, and a soldering portion protruding from the base to the outside in the second direction and soldered to the board. The above-mentioned shield main body wall is located outside the above-mentioned base in the second direction, that is, on the side where the soldering portion protrudes and opposite to the second housing. In other words, the shield main body wall covering the main body wall forming the movable space of the movable housing between the second housing and the base is arranged shifted to the outside in the second direction (opposite to the second housing) with respect to the base of the shield extension wall. The soldering portion protruding from the base to the outside in the second direction is arranged retracted to the inside in the second direction together with the base. This makes it easier to ensure both the movable space of the second housing, which is the movable housing, and the soldering strength of the shield, even when the occupation area of ​​the present movable connector on the board is set small.

[0009] The second aspect of the movable connector is the same as the first aspect, in which the shield main body wall portion, the shield extension wall portion, and the shield connection portion are integrally formed from a metal plate, and the shield connection portion has a bent portion that bends toward the inside in the second direction, and a portion of it is arranged with its plate thickness direction facing in the first direction.

[0010] In the movable connector of the second aspect, the shield body wall, the shield extension wall, and the shield connection part are integrally formed from a metal plate. The shield connection part has a bent part that bends toward the inside in the second direction, and a part of the shield connection part is arranged with its plate thickness direction facing the first direction. This makes it easy to set the dimension of the shield connection part in the first direction to be short when the base part of the shield extension wall that is connected to the shield body wall part via the shield connection part is moved toward the inside in the second direction.

[0011] A third aspect of the movable connector is the second aspect, wherein the shield is elongated when unfolded in a plane and has the shield main body wall portion at the middle portion in the longitudinal direction, and the shield main body wall portion is provided with a carrier cutting portion that is cut off from a carrier for progressive processing.

[0012] In the movable connector of the third aspect, the shield body wall of the metal shield is provided with a carrier cut-off portion cut from the progressive processing carrier. This shield body wall is provided in the longitudinal middle portion of the shield in the planar development state. In other words, the shield in the planar development state is connected to the progressive processing carrier at the longitudinal middle portion. Therefore, the deflection of the shield (blank) during progressive processing is smaller than when, for example, the shield in the planar development state is connected to the carrier at one longitudinal end portion. This makes it possible to improve the dimensional accuracy of the shield.

[0013] A fourth aspect of the movable connector is any one of the first to third aspects, in which the first housing is made of resin, a weld line formed in the first housing is covered by the shield, and the shield is held by the first housing on both sides in a direction perpendicular to the weld line.

[0014] In the movable connector of the fourth aspect, the weld line formed in the resin first housing is covered by the shield, and the shield is held by the first housing on both sides in the direction perpendicular to the weld line, thereby making it possible to prevent the first housing from being damaged at the weld portion including the weld line.

[0015] The fifth aspect of the shield manufacturing method is a method for manufacturing a metal shield to be attached to the housing of a movable connector by progressive processing, and includes a punching process in which a metal plate is punched including an outer shape punch to form a long blank connected to a carrier for progressive processing, a bending process in which the blank is bent to form the shield connected to the carrier, and a cutting process in which the shield is separated from the carrier, wherein in the punching process, only the longitudinal center side of one short end of the blank is connected to the carrier, and in the bending process, a crank-shaped bent portion is formed at the longitudinal end side of the blank.

[0016] In the manufacturing method of the shield of the fifth aspect, a metal shield to be attached to a housing of a movable connector is manufactured by progressive processing. In this manufacturing method, first, in a punching process, a metal plate is punched including an outer shape punching process to form a long blank connected to a carrier for progressive processing. Next, in a bending process, the blank is bent to form a shield connected to the carrier. Next, in a cutting process, the shield is separated from the carrier. In the punching process, only the longitudinal center side of one end in the short side direction of the blank is connected to the carrier. For example, compared with the case where the blank is connected to the carrier at one end in the long side direction, the runout of the blank during progressive processing is reduced. This makes it possible to improve the dimensional accuracy of the shield. Moreover, since only the longitudinal center side of one end in the short side direction of the blank is connected to the carrier as described above, a crank-shaped bent portion can be formed at the longitudinal end side of the blank in the bending process. As a result, when manufacturing the shield of the movable connector of, for example, any one of the first to fourth aspects, the crank-shaped bent portion can be set in the shield connecting portion, and the base of the shield main body wall portion and the shield extension wall portion can be shifted in the second direction. Therefore, this manufacturing method of the shield is suitable for manufacturing the shield of the movable connector of any one of the first to fourth aspects. Effect of the Invention

[0017] As described above, in the movable connector according to the present invention, even if the occupied area on the board is set small, it is easy to ensure both the movable space of the second housing, which is the movable housing, and the soldering strength of the shield. In addition, the manufacturing method of the shield according to the present invention is suitable for manufacturing the shield of the movable connector according to the present invention.

[0023] This movable connector 10 constitutes a plug (male type) of a board-to-board connector, and the mating connector, which is a receptacle (female type), is configured to be fixed to a mating circuit board separate from the circuit board 11. This mating connector is provided with a plurality of mating signal terminals (not shown) that are electrically connected to the plurality of signal terminals 50, and a plurality of mating power terminals (not shown) that are electrically connected to the plurality of power terminals 70. Note that the object to which the movable connector 10 is connected is not limited to a receptacle (connector), and may be a bus bar or a square pin.

[0024] The terminal arrangement direction X corresponds to the "first direction" in the present invention, and the bridge direction Y corresponds to the "second direction" in the present invention.

In the following description, the terminal arrangement direction X may be referred to as the "front-rear direction", the bridge direction Y may be referred to as the "left-right direction", and the insertion / removal direction Z may be referred to as the "up-down direction". The movable connector 10 is formed to be symmetrical in the front-rear direction and the left-right direction.

[0025] (About the moving housing) As shown in FIG. 5, the movable housing 14 is formed in a substantially rectangular tubular shape (substantially rectangular parallelepiped shape) with a bottom, having a rectangular bottomed hole 16 that opens upward. The movable housing 14 is integrally provided with a pair of left and right side wall portions 14A, 14B facing each other in the left-right direction, a pair of front and rear connecting wall portions 14C, 14D that connect the front and rear ends of the left and right side wall portions 14A, 14B in the left-right direction, and a bottom wall portion 14E (see FIG. 2) that connects the left and right side wall portions 14A, 14B in the left-right direction and connects the front and rear connecting wall portions 14C, 14D in the front-rear direction. The left and right side wall portions 14A, 14B extend in the front-rear direction, and the front and rear connecting wall portions 14C, 14D extend in the left-right direction. The bottom wall portion 14E is provided in the substantially lower half of the movable housing 14, and is formed thick in the vertical direction. The movable housing 14 is manufactured from an insulating material such as synthetic resin. In addition, the movable housing 14 in this embodiment is formed in an elongated shape with its longitudinal direction extending in the front-to-rear direction, but the dimension of the movable housing 14 in the front-to-rear direction can be changed as appropriate depending on the number of signal terminals 50.

[0026] A pair of front and rear engaging protrusions 18 protruding outward in the front-rear direction (outward in the terminal arrangement direction X) are formed at the lower ends of the front and rear connecting walls 14C, 14D (both front and rear ends of the movable housing 14). The front and rear engaging protrusions 18 are formed in a rectangular parallelepiped shape.

[0027] A plurality of signal terminal insertion grooves 20 extending in the vertical direction are formed in the surfaces of the left and right side walls 14A, 14B facing the bottomed hole 16 at equal intervals in the front-rear direction. These signal terminal insertion grooves 20 open toward the bottomed hole 16 and upward. These signal terminal insertion grooves 20 are also connected to a plurality of signal terminal insertion holes 21 (see FIG. 2) that penetrate the bottom wall 14E in the vertical direction.

[0028] A pair of left and right accommodating recesses 22 that open toward the outside in the front-rear direction are formed in the front-rear connecting wall portions 14C, 14D. The left and right accommodating recesses 22 extend in the vertical direction and communicate with a pair of left and right through holes 24 formed in the base end of the engaging protrusion 18. These through holes 24 penetrate the base end of the engaging protrusion 18 in the vertical direction. The lower ends of the left and right accommodating recesses 22 communicate with a pair of left and right elastic part insertion grooves (not shown) formed in the lower surface of the movable housing 14. The left and right elastic part insertion grooves extend in the horizontal direction and open toward both sides in the horizontal direction. In addition, spring accommodating recesses 28 are formed on both sides in the horizontal direction in the approximately lower half of the front and rear connecting wall portions 14C, 14D. The pair of left and right spring accommodating recesses 28 open toward the outside in the front-rear direction and the outside in the horizontal direction. Furthermore, above the left and right spring accommodating recesses 28, shell holding holes 29 that open downward are formed in the front and rear connecting wall portions 14C, 14D.

[0029] (Regarding fixed housing) As shown in Fig. 6, the fixed housing 30 is formed in a substantially rectangular frame shape having a rectangular through hole 33 penetrating in the up-down direction. The fixed housing 30 integrally includes a pair of left and right side wall portions 30A, 30B facing each other in the left-right direction, and a pair of front and rear connecting wall portions 30C, 30D connecting both front and rear end portions of the left and right side wall portions 30A, 30B in the left-right direction. The left and right side wall portions 30A, 30B extend in the front-rear direction (first direction), and the front and rear connecting wall portions 30C, 30D extend in the left-right direction (second direction). The front-rear direction intermediate portions of the left and right side wall portions 30A, 30B are respectively defined as main body wall portions 31, and the front-rear direction both end portions of the left and right side wall portions 30A, 30B are respectively defined as extension wall portions 32. The main body wall 31 protrudes upward beyond the extension wall 32, and each extension wall 32 is adjacent to the main body wall 31 in the front-rear direction (first direction). The front-rear end portions of the left and right side wall portions 30A, 30B and the front and rear connecting wall portions 30C, 30D are set to have the same vertical dimensions. This fixed housing 30 is manufactured from an insulating material such as synthetic resin. Note that the fixed housing 30 according to this embodiment is formed in an elongated shape with the front-rear direction as the longitudinal direction, but the front-rear dimension of the fixed housing 30 is configured to be appropriately changed depending on the number of signal terminals 50.

[0030] Approximately the lower half of the movable housing 14 is inserted into the inside of the through hole 33 of the fixed housing 30, and approximately the upper half of the movable housing 14 is disposed on the upper side (outside) of the fixed housing 30. A movable space 34 (see FIG. 2) having an approximately rectangular ring shape when viewed from the top-bottom direction is formed between the inner peripheral surface of the through hole 33 of the fixed housing 30 and the outer peripheral surface of approximately the lower half of the movable housing 14. The main body wall portions 31 of the side wall portions 30A, 30B of the fixed housing 30 face the movable housing 14 from the outside in the left-right direction (second direction).

[0031] A plurality of signal terminal insertion grooves 36 extending in the vertical direction are formed in the main body wall portion 31 of the left and right side wall portions 30A and 30B at equal intervals in the front-rear direction. The plurality of signal terminal insertion grooves 36 are open to the inside in the left-right direction (the center side in the left-right direction) and to the lower side. In addition, in the extension wall portion 32 of the left and right side wall portions 30A and 30B, a power terminal insertion hole 37 penetrating in the vertical direction is formed in a portion adjacent to the main body wall portion 31. Furthermore, in the extension wall portion 32 of the left and right side wall portions 30A and 30B, on both sides in the front-rear direction relative to the power terminal insertion hole 37, a recess 38 recessed inward in the left-right direction is formed. Each recess 38 is open to the outside in the left-right direction and both up-down directions. In addition, a fixed shell holding groove 39 is formed in each extension wall portion 32 on the inside in the left-right direction (rear side) of each recess 38. The fixed shell holding groove 39 is open to the outside in the left-right direction and both up-down directions. Further, in the left and right side wall portions 30A, 30B, a movable shell holding groove (not shown) is formed on the left and right inner side of the fixed shell holding groove 39. The movable shell holding groove and the fixed shell holding groove 39 are in communication with each other.

[0032] The front and rear connecting walls 30C and 30D are each provided with an engagement recess 40 recessed upward at the lower part of the left-right direction middle part. The front and rear engaging protrusions 18 formed on the movable housing 14 are disposed in the front and rear engaging recesses 40. The upper surface of each engaging protrusion 18 is in contact with or close to the upper surface of each engaging recess 40 and faces it. These engaging protrusions 18 and engaging recesses 40 function as stoppers to prevent the movable housing 14 from falling off upward relative to the fixed housing 30. In addition, gaps are formed between the left and right side surfaces of each engaging protrusion 18 and the left and right side surfaces of each engaging recess 40 to allow the movable housing 14 to be displaced relative to the fixed housing 30. In addition, a weld line WL is formed in the left-right direction center part of one of the front and rear connecting walls 30C and 30D (here, the connecting wall 30C) that was generated when the fixed housing 30 was manufactured by injection molding.

[0033] (Signal terminals) As shown in FIG. 7, the signal terminals 50 are manufactured by punching out a conductive metal plate into a predetermined shape, and constitute a pair of left and right terminal rows 52A, 52B (see FIG. 4). The left and right terminal rows 52A, 52B each have a configuration in which a plurality of signal terminals 50 are arranged at equal intervals in the front-rear direction. The signal terminals 50 in the left terminal row 52A and the signal terminals 50 in the right terminal row 52B are formed to have the same shape, but are arranged in opposite orientations in the left-right direction. The signal terminals 50 in the left terminal row 52A are bridged between the left side wall portion 30A of the fixed housing 30 and the movable housing 14 in the left-right direction, and the signal terminals 50 in the right terminal row 52B are bridged between the right side wall portion 30B of the fixed housing 30 and the movable housing 14 in the left-right direction. FIG. 7 illustrates one signal terminal 50 in the left terminal row 52A and one signal terminal 50 in the right terminal row 52B.

[0034] Each signal terminal 50 has a first contact portion 50A that is held by the movable housing 14 and is in electrical contact with a mating signal terminal provided on the mating connector and elastically deforms outward in the left-right direction, a first elastic portion 50B that extends outward in the left-right direction from the first contact portion 50A and is elastically deformable, and a first connection portion 50C that extends outward in the left-right direction from the end of the first elastic portion 50B opposite the first contact portion 50A, is held by the fixed housing 30, and is fixed to the circuit board 11.

[0035] The first contact portion 50A is formed in a long plate shape with the plate thickness direction being the left-right direction and the longitudinal direction being the up-down direction, and is inserted from below into the signal terminal insertion groove 20 and the signal terminal insertion hole (not shown) of the movable housing 14. Approximately the lower half of this first contact portion 50A is made into a first holding portion 50A1 inserted (press-fitted) into the signal terminal insertion hole 21 of the movable housing 14. This first holding portion 50A1 is formed with a plurality of claw portions 54 arranged in the up-down direction and protruding on both sides in the front-rear direction. These plurality of claw portions 54 bite into the inner peripheral surface of the signal terminal insertion hole 21, so that the first holding portion 50A1 is held by the movable housing 14.

[0036] Approximately the upper half of the first contact portion 50A is a first contact elastic portion 50A2. The first contact elastic portion 50A2 is inserted into the signal terminal insertion groove 20 of the movable housing 14 and is elastically deformable in the left-right direction. A first contact portion 56 protruding into the bottomed hole 16 of the movable housing 14 is formed on the upper portion of the first contact elastic portion 50A2. The first contact portion 56 is brought into contact with a mating signal terminal provided in a mating connector. This results in a configuration in which the signal terminal 50 is electrically connected to the mating signal terminal.

[0037] The first connection portion 50C has a first press-fit portion 50C1 inserted (press-fitted) into the signal terminal insertion groove 36 of the fixed housing 30 from below, and a first board connection portion 50C2 extending outward in the left-right direction from the lower end of the first press-fit portion 50C1, and is formed in a substantially L-shape when viewed in the front-rear direction. The first press-fit portion 50C1 is formed with claw portions 60 protruding on both sides in the front-rear direction. These claw portions 60 are hooked on the inner peripheral surface of the signal terminal insertion groove 36, so that the first press-fit portion 50C1 is held by the fixed housing 30. The first board connection portion 50C2 protrudes in the plane direction of the circuit board 11 (here, outward in the left-right direction) relative to the fixed housing 30. The base end side portion (the portion on the first press-fit portion 50C1 side) of the first board connection portion 50C2 is inclined upward toward the inside in the left-right direction, and the tip side portion is formed parallel to the plane of the circuit board 11. The tip end portion of this first board connection portion 50C2 is configured to be fixed (electrically connected) to the circuit board 11 by means of soldering or the like.

[0038] The first elastic portion 50B constitutes a left-right intermediate portion of the signal terminal 50, and extends outward and upward in the left-right direction from the lower end of the first contact portion 50A. The first connection portion 50C extends integrally from the end of the first elastic portion 50B opposite to the first contact portion 50A.

[0039] (About the power terminal) As shown in FIG. 8, the power terminals 70 are manufactured by punching out a conductive metal plate and bending the metal plate. In this embodiment, a pair of left and right power terminals 70 are arranged on both sides of the movable housing 14 in the front-rear direction. The left and right power terminals 70 are formed to be symmetrical to each other in the left-right direction. The left and right power terminals 70 arranged on the front side of the movable housing 14 and the left and right power terminals 70 arranged on the rear side of the movable housing 14 are arranged in opposite orientations to each other in the front-rear direction. The left power terminal 70 is bridged between the left side wall portion 30A of the fixed housing 30 and the movable housing 14 in the left-right direction, and the right power terminal 70 is bridged between the right side wall portion 30B of the fixed housing 30 and the movable housing 14 in the left-right direction.

[0040] Each power supply terminal 70 has a second contact portion 70A that is held by the movable housing 14 and is in electrical contact with a mating power supply terminal provided on the mating connector and elastically deforms inward in the front-to-rear direction, a second elastic portion 70B that extends outward in the left-right direction from the second contact portion 70A and is elastically deformable, and a second connection portion 70C that extends outward in the left-right direction from the end of the second elastic portion 70B opposite the second contact portion 70A, is held by the fixed housing 30, and is fixed to the circuit board 11.

[0041] The second contact portion 70A is formed in an elongated plate shape with the plate thickness direction being the front-rear direction and the longitudinal direction being the up-down direction, and is inserted from below into the through hole 24 and the accommodation recess 22 of the movable housing 14. Approximately the lower half of this second contact portion 70A is a second holding portion 70A1 inserted (press-fitted) into the through hole 24 of the movable housing 14. This second holding portion 70A1 is formed with a plurality of claw portions 72 arranged in the up-down direction and protruding on both the left-right sides. These plurality of claw portions 72 bite into the inner circumferential surface of the through hole 24, so that the second holding portion 70A1 is held by the movable housing 14.

[0042] Approximately the upper half of the second contact portion 70A is the second contact elastic portion 70A2. The second contact elastic portion 70A2 is inserted into the accommodation recess 22 of the movable housing 14 and is elastically deformable in the front-rear direction. A second contact portion 71 is formed on the upper portion of the second contact elastic portion 70A2, protruding outward in the front-rear direction beyond the movable housing 14. The second contact portion 71 is brought into contact with a mating power terminal provided on the mating connector. This results in a configuration in which the power terminal 70 is electrically connected to the mating power terminal.

[0043] The second connection portion 70C has a second press-fit portion 70C1 inserted (press-fitted) into the power terminal insertion hole 37 of the fixed housing 30 from below, and a second board connection portion 70C2 extending outward in the left-right direction from the lower end of the second press-fit portion 70C1, and is formed in a substantially L-shape when viewed in the front-rear direction. The second press-fit portion 70C1 is formed with a claw portion 78 protruding inward in the left-right direction. The claw portion 78 is hooked on the inner peripheral surface of the power terminal insertion hole 37, so that the second press-fit portion 70C1 is held by the fixed housing 30. The second board connection portion 70C2 protrudes in the planar direction of the circuit board 11 (here, outward in the left-right direction) relative to the fixed housing 30. The second board connection portion 70C2 is configured to be fixed (electrically connected) to the circuit board 11 by means of soldering or the like.

[0044] The second elastic portion 70B constitutes the left-right intermediate portion of the power terminal 70, and extends outward in the left-right direction from the lower end of the second contact portion 70A. The second connection portion 70C extends integrally from the end of the second elastic portion 70B opposite the second contact portion 70A. The left-right intermediate portion of the second elastic portion 70B is a second spring portion 70B1 bent upward in an inverted U-shape. The left-right inner portion of the second spring portion 70B1 is accommodated in the left and right spring accommodating recesses 28 of the movable housing 14.

[0045] (About the movable shell) 9, the movable shell 82 is manufactured by punching out a metal plate and then bending it. In this embodiment, a movable shell 82 is disposed on each of the left and right sides of the movable housing 14. The left and right movable shells 82 are formed to have the same shape, but are disposed in opposite orientations in the left-right direction. The movable shell 82 is configured so that it is held by the movable housing 14 by press-fitting before the housing 12 is placed on the circuit board 11, and a portion of it is also held by press-fitting into the fixed housing 30.

[0046] Each movable shell 82 is integrally provided with a movable shell main body 82A covering the left and right side surfaces of the movable housing 14, a pair of front and rear movable side holding portions 82B extending in the front and rear directions from both front and rear end portions of the movable shell main body 82A, a pair of front and rear downward extending portions 82C extending downwardly from the front and rear movable side holding portions 82B, a pair of front and rear spring portions 82D extending outward in the left and right directions from the lower end portions of the front and rear downward extending portions 82C, a pair of front and rear fixed side holding portions 82E extending from the end portions of the front and rear spring portions 82D opposite the downward extending portions 82C, and a pair of front and rear fixed side connecting portions 82F extending from the opposite side of the front and rear fixed side holding portions 82E from the spring portions 82D.

[0047] The movable shell body 82A is a long rectangular plate with the longitudinal direction being the longitudinal direction and the plate thickness direction being the lateral direction, and is overlapped on the left and right side surfaces of the movable housing 14. The front and rear movable side holding parts 82B extend obliquely from the lower part of both ends of the movable shell body 82A in the front-rear direction outwardly and inwardly in the lateral direction, and then extend outwardly and upwardly in the front-rear direction. The upper extension parts 82B1 extending upward in these movable side holding parts 82B are inserted from the lower side into the front and rear shell holding holes 29 formed in the movable housing 14. Each upper extension part 82B1 is formed with a pair of upper and lower claw parts 84 protruding toward the center in the front-rear direction. The front and rear movable side holding parts 82B are held by the movable housing 14 by these claw parts 84 biting into the inner circumferential surface of the shell holding hole 29, and the movable shell body 82A is held by the movable housing 14 via these movable side holding parts 82B.

[0048] The front and rear downward extensions 82C extend downward in a straight line from the lower ends of the front and rear movable holding parts 82B, and their lower ends are disposed in the vicinity of the upper part of the circuit board 11. The front and rear spring parts 82D extend outward and upward in the left-right direction from the lower ends of the front and rear downward extensions 82C, and then bend downward, forming a substantially inverted U-shape when viewed in the front-rear direction. The front and rear spring parts 82D and the downward extensions 82C have spring properties.

[0049] The front and rear fixed side holding parts 82E extend outward in the front-rear direction from the outer ends of the front and rear spring parts 82D in the left-right direction and then extend upward. The upper extension parts 82E1 extending upward in these fixed side holding parts 82E are inserted from the lower side into the movable shell holding grooves (not shown) formed at both the front and rear ends of the fixed housing 30. Each upper extension part 82E1 has a plurality of claw parts 86 arranged in the vertical direction and protruding on both sides in the front-rear direction. These plurality of claw parts 86 bite into the inner circumferential surface of the movable shell holding groove, so that the front and rear fixed side holding parts 82E are held by the fixed housing 30. The front and rear fixed side connecting parts 82F extend outward in the left-right direction and downward from the upper ends of the front and rear fixed side holding parts 82E. The tip parts of these fixed side connecting parts 82F are elastically pressed against a base part 95 of the fixed shell 92, which will be described later. This results in a configuration in which the movable shell 82 and the fixed shell 92 are electrically connected.

[0050] (Regarding fixed shell) 10, the fixed shell 92 is manufactured by punching out a metal plate and then bending it. The fixed shell 92 is configured to be held in the fixed housing 30 by press-fitting before the housing 12 is placed on the circuit board 11. The fixed shell 92 includes a pair of left and right side wall covering parts 92A, 92B that cover the left and right side wall parts 30A, 30B of the fixed housing 30, a pair of front and rear connecting wall covering parts 92C, 92D that cover the front and rear connecting wall parts 30C, 30D, and a plurality of (here, four) extended wall parts 92E that are disposed on the extended wall parts 32 of the left and right side wall parts 30A, 30B of the fixed housing 30.

[0051] The left and right side wall covering parts 92A, 92B include a main body wall part 93 that covers the main body wall part 31 of the side wall parts 30A, 30B from the outside in the left-right direction (outside in the second direction), an upper wall part 94 that extends from the upper end part of the main body wall part 93 in the left-right direction to cover the side wall parts 30A, 30B from above, and a front wall part 98 and a rear wall part 100 that extend from the upper part of the front end part of the main body wall part 93 in the left-right direction to cover the side wall parts 30A, 30B from the outside in the front-rear direction. The main body wall part 93 corresponds to the "shield main body wall part" in the present invention. Hereinafter, the main body wall part 93 is referred to as the "shield main body wall part 93". The left and right side wall covering parts 92A, 92B including the shield main body wall part 93 are elongated in the front-rear direction.

[0052] Left and right first covering portions (first extending portions) 112 extend from the lower ends of the left and right shield main body wall portions 93. Each first covering portion 112 extends obliquely from the lower end of each shield main body wall portion 93 toward the outside and downward in the left-right direction in the front-rear direction region in which the multiple signal terminals 50 are arranged, and extends further outward in the left-right direction than the first board connecting portions 50C2 of the multiple signal terminals 50. These first covering portions 112 cover the first board connecting portions 50C2 of the multiple signal terminals 50 from above and from the outside in the left-right direction.

[0053] Further, second covering parts (second extending parts) 114 are disposed near the outer sides of the first covering parts 112 in the front-rear direction. Each second covering part 114 extends from the lower end of the shield main body wall part 93 in the left and right sidewall covering parts 92A, 92B of the fixed shell 92. Each second covering part 114 extends outward in the left-right direction from the lower end of each shield main body wall part 93 in the front-rear direction region where the power terminal 70 is disposed, and covers the second board connection part 70C2 of the power terminal 70 from above. Note that the pair of front and rear second covering parts 114 provided on one of the left and right sidewall covering parts 92A, 92B (here, the sidewall covering part 92A) corresponds to the "carrier disconnecting part" in the present invention. Hereinafter, the pair of front and rear second covering parts 114 provided on the sidewall covering part 92A will be referred to as the "pair of carrier disconnecting parts 114".

[0054] The front and rear connecting wall covering portions 92C, 92D include a vertical wall portion 102 that covers the connecting wall portions 30C, 30D from the outside in the front-rear direction, and an upper wall portion 104 that extends from the upper end of the vertical wall portion 102 toward the center in the front-rear direction and covers the connecting wall portions 30C, 30D from above. The vertical wall portion 102 protrudes outward in the left-right direction beyond the upper wall portion 104.

[0055] The four extension walls 92E correspond to the "shield extension walls" in the present invention. Hereinafter, the extension walls 92E are referred to as "shield extension walls 92E." Each shield extension wall 92E has a base 95 that covers each extension wall 32 from the outside in the left-right direction (outside in the second direction) and a soldering portion 96 that protrudes from the base 95 to the outside in the left-right direction (outside in the second direction) and is soldered to the circuit board 11.

[0056] The bases 95 of the shield extension walls 92E are disposed on both sides of the left and right side wall covering parts 92A and 92B in the front-rear direction. Each base 95 is plate-shaped with the plate thickness direction being in the left-right direction, and is inserted from above into each of the four fixed shell holding grooves 39 formed in the fixed housing 30. A plurality of claws 106 protruding on both sides in the front-rear direction are formed in each base 95 in a line in the up-down direction. These claws 106 bite into the inner circumferential surface of each fixed shell holding groove 39, thereby holding each base 95 in the fixed housing 30. The fixed side connection part 82F of the movable shell 82 is pressed against these bases 95 from the inside in the left-right direction.

[0057] An upper wall connection part 108 having an arc shape in a front-rear view extends from the upper end of each base part 95. The upper wall connection part 108 extends upward and inward in the left-right direction, and is connected to the left-right end of the upper wall part 104 of the connecting wall covering part 92C or 92D. A main body wall connection part 110 having a crank shape in a plan view (up-down view) extends from the upper part of the center end of the front-rear direction of each base part 95. The main body wall connection part 110 extends outward in the left-right direction and then bends toward the center in the front-rear direction, and is connected to the front-rear end of the shield main body wall part 93 of the side wall covering part 92A or 92B. The main body wall connection part 110 corresponds to the "shield connection part" in the present invention. Hereinafter, the main body wall connection part 110 is referred to as the "shield connection part 110". The shield connecting portion 110 connects the shield main body wall portion 93 and the base portion 95 of the shield extension wall portion 92E.

[0058] The four soldering portions 96 are plate-shaped with the thickness direction being in the up-down direction, and extend outward in the left-right direction (outward in the second direction) from the lower end of each base portion 95. These soldering portions 96 are configured to be fixed (electrically connected) to the GND circuit of the circuit board 11 by means of soldering or the like. This fixes the fixed shell 92 to the circuit board 11, and prevents the fixed housing 30 from peeling off from the circuit board 11.

[0059] 2, in the fixed shell 92 having the above-mentioned configuration, the shield main body wall 93 is located outside in the left-right direction (outside in the second direction) from the base 95 of the shield extension wall 92E. That is, the shield main body wall 93, which covers the main body wall 31 of the fixed housing 30 that forms the movable space 34 of the movable housing 14 between itself and the movable housing 14 and is disposed shifted outside in the left-right direction (opposite the movable housing 14) from the base 95 of the shield extension wall 92E. Also, the fixed housing 30 has a recess 38 recessed inward in the left-right direction at a position corresponding to the base 95 and the soldering portion 96, and the base 95 and the soldering portion 96 are disposed retracted inward in the left-right direction.

[0060] As described above, the fixed shell 92 having the above configuration is manufactured by punching and bending a metal plate, and the shield main body wall 93, the base 95 of the shield extension wall 92E, and the shield connecting portion 110 are integrally formed by the metal plate. As shown in Fig. 11, the shield connecting portion 110 has a bent portion 110A that bends toward the inside in the left-right direction (the inside in the second direction), and a part 110B of the shield connecting portion 110 is disposed with its plate thickness direction facing the front-rear direction (the first direction). Note that the reference numerals of the bent portion 110A and the part 110B are omitted in figures other than Fig. 11.

[0061] In addition, in the resin fixed housing 30 to which the fixed shell 92 having the above-mentioned configuration is attached, the weld line WL formed in the left-right center of the connecting wall 30C is covered from the front-rear direction outer side and the upper side by the vertical wall 102 and the upper wall 104 of the connecting wall covering part 92C. The fixed shell 92 is held by the fixed housing 30 on both sides (here, the left and right sides) in the direction perpendicular to the weld line WL. Specifically, on the left and right sides of the connecting wall 30C, the base 95 of the shield extension wall 92E is held by the extension wall 32 of the fixed housing 30. This prevents the connecting wall 30C from being damaged (broken in the left-right direction) at the weld part including the weld line WL. In this embodiment, the fixed shell 92 has four shield extension walls 92E, but this is not limited to this. For example, in the fixed shell 92, the front and left shield extension wall portion 92E and the rear and right shield extension wall portion 92E may be omitted, or the front and right shield extension wall portion 92E and the rear and left shield extension wall portion 92E may be omitted.

[0062] The fixed shell 92 having the above-mentioned configuration is manufactured by progressive processing (progressive press processing), and the shield main body wall portion 93 is provided with a pair of carrier cut portions 114 cut from a progressive processing carrier C (see FIG. 12). The fixed shell 92 is manufactured using a progressive die (not shown). In the manufacturing method of the fixed shell, first, in a punching process, a long strip-shaped metal plate is punched including punching an outer shape to form a long blank B (see FIG. 12) connected to the progressive processing carrier C. The blank B corresponds to the "shield in a planar development state" in the present invention, and has a long shape.

[0063] The longitudinal middle part of the blank B is constituted by sidewall covering parts 92A, 92B including a shield main body wall part 93, and the longitudinal both end parts are constituted by connecting wall covering parts 92C, 92D, a shield extension wall part 92E, a shield connecting part 110, etc. At one lateral end part of the blank B, both longitudinal end parts of the shield main body wall part 93 of the sidewall covering part 92A are connected to the carrier C via a pair of carrier connecting parts C1 which are connected to a pair of carrier cutting parts 114. In other words, this blank B is constituted such that only the longitudinal center side at one lateral end part is connected to the carrier C via a pair of carrier connecting parts C1.

[0064] The above punching step is followed by a bending step. In this bending step, the blank B is bent to form the fixed shell 92 connected to the carrier C via a pair of carrier connecting parts C1. In this bending step, a crank-shaped bent part is formed on the longitudinal end of the blank B. The part where this bent part is formed corresponds to the shield connecting part 110. This bending step is followed by a cutting step. In the cutting step, the pair of carrier connecting parts C1 are cut near the shield main body wall part 93 of the side wall covering part 92A, and the fixed shell 92 is separated from the carrier C. This completes the fixed shell 92.

[0065] (Action and Effects) Next, the operation and effects of this embodiment will be described.

[0066] In the movable connector 10 having the above-mentioned configuration, a plurality of signal terminals 50 and a pair of power terminals 70 are bridged between a pair of side walls 30A, 30B of the fixed housing 30 and the movable housing 14. The signal terminals 50 are arranged in a front-rear direction (terminal arrangement direction X) perpendicular to the up-down direction (insertion / removal direction Z) and the left-right direction (bridge direction Y), and have a first elastic portion 50B that can be elastically deformed in the middle of the bridge direction Y. The pair of power terminals 70 are arranged on both sides of the signal terminals 50 in the terminal arrangement direction X, and bridge between the pair of side walls 30A, 30B. The middle portions of these power terminals 70 in the bridge direction Y are held by the ends of the movable housing 14 in the terminal arrangement direction X, and have second elastic portions 70B that can be elastically deformed in the portions located between the pair of side walls 30A, 30B and the movable housing 14.

[0067] In this movable connector 10, the first elastic portion 50B of each signal terminal 50 and the pair of second elastic portions 70B of each power terminal 70 are elastically deformable, allowing relative displacement of the movable housing 14 with respect to the fixed housing 30. This makes it possible to absorb fitting misalignment between the movable connector 10 and the mating connector.

[0068] In addition, in this movable connector 10, the signal terminals 50 held in the housing 12 placed on the circuit board 11 have a first board connection portion 50C2 connected to the circuit board 11, and noise is shielded by a shell 80 covering the housing 12. This shell 80 is composed of left and right movable shells 82 covering the movable housing 14, and a fixed shell 92 covering the fixed housing 30, and the above-mentioned relative displacement is allowed by elastic deformation of a spring portion 82D of the movable shell 82.

[0069] In this movable connector 10, the fixed housing 30 extends in the front-rear direction (first direction) along the plane of the circuit board 11, and has a main body wall 31 facing the movable housing 14 from the outside in the left-right direction (second direction), and an extension wall 32 adjacent in the front-rear direction to the main body wall 31. The fixed shell 92 of the shell 80 has a shield main body wall 93 covering the main body wall 31 from the outside in the left-right direction (i.e., the side opposite the movable housing 14), a shield extension wall 92E arranged on the extension wall 32, and a shield connection part 110 connecting the shield main body wall 93 and the shield extension wall 92E.

[0070] The shield extension wall 92E has a base 95 held by the extension wall 32 of the fixed housing 30, and a soldering portion 96 that protrudes from the base 95 outward in the left-right direction and is soldered to the circuit board 11. The shield main body wall 93 is located outside the base 95 of the shield extension wall 92E in the left-right direction, that is, on the side where the soldering portion 96 protrudes and opposite the movable housing 14. In other words, the shield main body wall 93 that covers the main body wall 31 that forms the movable space 34 of the movable housing between the movable housing 14 and the base 95 from the outside in the left-right direction is arranged outward in the left-right direction (opposite the movable housing 14) with respect to the base 95 of the shield extension wall 92E. The soldering portion 96 that protrudes from the base 95 outward in the left-right direction is arranged retracted inward in the left-right direction together with the base 95. As a result, even if the area occupied by the movable connector 10 on the circuit board 11 is set small, it becomes easier to simultaneously ensure the movable space 34 of the movable housing 14 and the soldering strength of the fixed shell 92.

[0071] In addition, in this movable connector 10, the weld line WL formed in the resin fixed housing 30 is covered by the fixed shell 92, and the base 95 of the shield extension wall 92E of the fixed shell 92 is held by the extension wall 32 of the fixed housing 30 on both sides (left and right sides) in the direction perpendicular to the weld line WL. This makes it possible to prevent the fixed housing 30 from being damaged at the weld portion including the weld line WL.

[0072] In addition, in the movable connector 10, the shield body wall 93, the shield extension wall 92E, and the shield connection part 110 are integrally formed of a metal plate. The above-mentioned shield connection part 110 has a bent part 110A that is bent toward the inside in the second direction, and a part 110B faces the plate thickness direction in the first direction. This makes it easy to set the dimension of the shield connection part 110 in the first direction short when the base part 95 of the shield extension wall part 92E that is connected to the shield body wall part 93 via the shield connection part 110 is retracted toward the inside in the second direction. Moreover, since the shield connection part 110 does not protrude toward the movable space 34, it is possible to prevent the movable space 34 from being narrowed by the shield connection part 110.

[0073] In addition, in this movable connector 10, a carrier cut portion 114 cut from a carrier C for progressive processing is provided on a shield body wall portion 93 of a metal fixed shell 92. This shield body wall portion 93 is provided in a longitudinal middle portion of the fixed shell 92 in a planarly developed state. That is, the fixed shell 92 in a planarly developed state is connected to the carrier C for progressive processing at a longitudinal middle portion. Therefore, the deflection of the fixed shell 92 (blank B) during progressive processing is smaller than when, for example, the fixed shell 92 in a planarly developed state is connected to the carrier C at one longitudinal end portion. This makes it possible to improve the dimensional accuracy of the fixed shell 92.

[0074] The above effects will be further explained with reference to Figs. 13 and 14. In the manufacturing method of the fixed shell 92, first, in the punching process, a metal plate is punched including punching an outer shape to form a long blank B connected to a carrier C for progressive processing. Next, in the bending process, the blank B is bent to form a shield connected to the carrier C. Next, in the cutting process, the fixed shell 92 is separated from the carrier C. In the punching process, only the center side in the longitudinal direction at one end in the lateral direction of the blank B is connected to the carrier C. Therefore, compared to, for example, a configuration in which the blank B is connected to the carrier C at one end in the longitudinal direction (see the first comparative example shown in Fig. 13), the runout of the blank B during progressive processing is reduced. This makes it possible to improve the dimensional accuracy of the fixed shell 92.

[0075] Moreover, since only the longitudinal center side at one end in the lateral direction of the blank B is connected to the carrier C as described above, in the bending process, a crank-shaped shield connection portion 110 (bent portion) can be formed at the longitudinal end side of the blank B. This allows the shield main body wall portion 93 and the base portion 95 of the shield extension wall portion 92E to be shifted in the left-right direction (second direction). That is, in a configuration in which both longitudinal ends of the blank B are connected to the carrier C as in the second comparative example shown in FIG. 14, the shield connection portion 110 cannot be formed into a crank shape, but this is possible in this embodiment. Therefore, the above manufacturing method is suitable for manufacturing the fixed shell 92 of the movable connector 10 according to this embodiment.

[0076] <Supplementary explanation of the embodiment> In the above embodiment, the shield connecting portion 110 of the fixed shell 92 has a bent portion 110A that bends inward in the left-right direction (second direction), and a part 110B of the shield connecting portion 110 is disposed with its plate thickness direction facing the front-rear direction (first direction), but the present invention is not limited to this. For example, as in a first modified example shown in Fig. 15, the shield connecting portion 110 may have a bent portion 110A that bends inward in the left-right direction (second direction), and a part 110B of the shield connecting portion 110 is disposed with its plate thickness direction facing the up-down direction.

[0077] In the above embodiment, each portion of the fixed shell 92 is integrally formed from a metal plate, but this is not limiting, and the fixed shell 92 may be divided into two in the left-right direction as in a second modified example shown in Fig. 16. In Fig. 16, DL denotes a dividing line of the fixed shell 92.

[0078] In the above embodiment, the configuration includes the signal terminal 50 as the first terminal and the power terminal 70 as the second terminal, but the present invention is not limited to this, and the second terminal may be omitted.

[0079] In addition, the present invention can be implemented in various modifications without departing from the spirit and scope of the present invention. Furthermore, the scope of the present invention is not limited to the above-described embodiment. [Explanation of symbols]
