Description

The present invention relates to a movable connector in which a shield is attached to a housing, and a method for manufacturing a shield that is attached to the housing of a movable connector.

The following Patent Document 1 discloses a movable connector. In this movable connector, a movable space is formed between the fixed housing and the movable housing. A terminal is bridged between the fixed housing and the movable housing, and a U-shaped movable spring part of the terminal elastically deforms within the movable space. This allows the movable housing to be displaced relative to the fixed housing. This movable connector also implements noise countermeasures by attaching a metal shell member (shield) to the fixed housing. This shield has a soldering part that protrudes in a direction along the plane of the board, and by soldering the soldering part to the board, the shield is conductive to the GND circuit of the board and peeling of the connector from the board is prevented.

JP 2013-45739 A

However, with the recent trend towards miniaturization of electronic devices, there is a demand for connectors mounted on circuit boards to occupy a small area on the circuit 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 circuit board).

The present invention aims to provide a movable connector that can easily secure 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 suitable for manufacturing the shield of the movable connector.

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 substrate, and a second housing elastically displaceably connected to the first housing via the terminal, the first housing extending in a first direction along the plane of the substrate, 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, and 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 disposed on the extension wall portion, and a shield connection portion connecting the shield main body wall portion and the shield extension wall portion, and the shield extension wall portion has a base portion covering the extension wall portion from the outside in the second direction, and a soldering portion protruding from the base portion to the outside in the second direction and soldered to the board, and the shield main body wall portion is located outside the base portion in the second direction.

In the first aspect of the movable connector, 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 above shield also 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.

The above-mentioned shield extension wall has a base that covers the extension wall of the first housing from the outside in the second direction, and a soldering portion that protrudes from the base to the outside in the second direction and is 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 the second housing. In other words, the shield main body wall that covers the main body wall that forms the movable space of the movable housing between the second housing and the base is shifted to the outside in the second direction (opposite the second housing) relative to the base of the shield extension wall. The soldering portion that protrudes from the base to the outside in the second direction is retreated 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 this movable connector on the board is set small.

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

In the second aspect of the movable connector, the shield body wall, the shield extension wall, and the shield connection part are integrally formed from a metal plate. The above-mentioned shield connection part has a bent part that bends inward in the second direction, and a part of it is arranged with its plate thickness direction facing in 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 of the shield extension wall part that connects to the shield body wall part via the shield connection part is retracted inward in the second direction and arranged.

The third aspect of the movable connector is the second aspect, in which the shield is elongated when unfolded in a plane and has the shield body wall at the middle in the longitudinal direction, and the shield body wall is provided with a carrier cut portion that is cut from a carrier for progressive processing.

In the movable connector of the third aspect, the shield body wall of the metal shield is provided with a carrier cut portion that is cut from the carrier for progressive processing. This shield body wall portion is provided in the longitudinal middle portion of the shield in the planar expanded state. In other words, the shield in the planar expanded state is connected to the carrier for progressive processing 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 expanded state is connected to the carrier at one longitudinal end portion. This makes it possible to improve the dimensional accuracy of the shield.

The 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.

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

The fifth aspect of the shield manufacturing method is a method for manufacturing a metal shield to be attached to a housing of a movable connector by progressive processing, and includes a punching process in which a metal plate is punched, including punching the outer shape, 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, in which only the longitudinal center side of one end of the blank in the lateral direction is connected to the carrier in the punching process, and in which a crank-shaped bent portion is formed on the longitudinal end side of the blank in the bending process.

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

As described above, with the movable connector of 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 of the present invention is suitable for manufacturing the shield of the movable connector of the present invention.

(composition)
1 to 3 show a movable connector 10 according to the present embodiment. The movable connector 10 is a so-called floating connector, and includes a housing 12 (see FIGS. 1 to 4) that is placed on a circuit board 11 (not shown except in FIG. 3). The housing 12 is composed of a movable housing 14 (see FIG. 5) into which a mating connector (not shown), which is a connection object, is inserted and removed, and a fixed housing 30 (see FIG. 6) that is fixed to the circuit board 11. The fixed housing 30 has a pair of side walls 30A and 30B that are arranged on both sides of the bridge direction (arrow Y direction) perpendicular to the insertion and removal direction (arrow Z direction) of the mating connector relative to the movable housing 14. The fixed housing 30 corresponds to the "first housing" in the present invention, and the movable housing 14 corresponds to the "second housing" in the present invention. The circuit board 11 corresponds to the "board" in the present invention, and the thickness direction of the circuit board 11 coincides with the insertion and removal direction Z. The planar direction of this circuit board 11 is a direction perpendicular to the insertion/removal direction Z described above.

The movable connector 10 also includes a plurality of signal terminals 50 (see Figures 4 and 7) that are bridged between the movable housing 14 and the pair of side walls 30A, 30B along the bridge direction Y and that are arranged in a terminal arrangement direction (arrow X direction) perpendicular to the insertion/removal direction Z and the bridge direction Y, and a plurality of power terminals 70 (see Figures 4 and 8) that are arranged on both sides of the signal terminals 50 in the terminal arrangement direction X and that are bridged between the movable housing 14 and the pair of side walls 30A, 30B along the bridge direction Y. The signal terminals 50 and the power terminals 70 correspond to the "terminals" in this invention.

The movable connector 10 further includes a shell 80 that covers the housing 12 and blocks noise. This shell 80 corresponds to the "shield" in the present invention, and is composed of a movable shell 82 (see FIG. 9) that covers the movable housing 14, and a fixed shell 92 (see FIG. 10) that covers the fixed housing 30.

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.

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. The terminal arrangement direction X and the bridge direction Y are directions along the plane (board surface) of the circuit board 11. In the present embodiment, the terminal arrangement direction X coincides with the front-rear direction of the movable connector 10, the bridge direction Y coincides with the left-right direction of the movable connector 10, and the insertion/removal direction Z coincides with the up-down direction of the movable connector 10. 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.

(Regarding the movable 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.

A pair of front and rear engaging protrusions 18 that protrude 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 wall portions 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.

On the surfaces of the left and right side walls 14A and 14B facing the bottomed hole 16, a number of signal terminal insertion grooves 20 extending in the vertical direction are formed 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 number of signal terminal insertion holes 21 (see FIG. 2) that penetrate the bottom wall 14E in the vertical direction.

A pair of left and right storage 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 storage 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 storage recesses 22 communicate with a pair of left and right elastic part insertion grooves (not shown) formed on 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 the left and right directions. In addition, spring storage recesses 28 are formed on both the left and right sides of the approximately lower half of the front and rear connecting wall portions 14C, 14D in the horizontal direction. The pair of left and right spring storage 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 storage recesses 28, shell holding holes 29 that open downward are formed in the front and rear connecting wall portions 14C, 14D.

(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 ends 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-back direction (first direction), and the front and rear connecting wall portions 30C, 30D extend in the left-right direction (second direction). The front-back intermediate portions of the left and right side wall portions 30A, 30B are respectively main body wall portions 31, and both ends of the left and right side wall portions 30A, 30B in the front-back direction are respectively extended wall portions 32. The main body wall portion 31 protrudes upward from the extended wall portion 32, and each extended wall portion 32 is adjacent to the main body wall portion 31 in the front-back 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. The fixed housing 30 is manufactured from an insulating material such as synthetic resin. The fixed housing 30 according to this embodiment is formed in an elongated shape with the front-rear direction as its length, but the front-rear dimension of the fixed housing 30 can be changed as appropriate depending on the number of signal terminals 50.

The lower half of the movable housing 14 is inserted into the inside of the through hole 33 of the fixed housing 30, and 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) that is approximately rectangular and annular 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 the lower half of the movable housing 14. The main body wall portions 31 of the side wall portions 30A and 30B of the fixed housing 30 face the movable housing 14 from the outside in the left-right direction (second direction).

In the main body wall 31 of the left and right side wall parts 30A and 30B, a plurality of signal terminal insertion grooves 36 extending in the vertical direction are formed 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 parts 32 of the left and right side wall parts 30A and 30B, a power terminal insertion hole 37 penetrating in the vertical direction is formed in the part adjacent to the main body wall part 31. Furthermore, in the extension wall parts 32 of the left and right side wall parts 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 part 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. In addition, in the left and right side wall portions 30A and 30B, a movable shell retaining groove (not shown) is formed on the left-right inner side of the fixed shell retaining groove 39. The movable shell retaining groove and the fixed shell retaining groove 39 are connected to each other.

The front and rear connecting wall portions 30C, 30D have engagement recesses 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 arranged 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 from 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 that was generated when the fixed housing 30 was manufactured by injection molding is formed in the left-right direction center part of one of the front and rear connecting wall portions 30C, 30D (here, connecting wall portion 30C).

(Regarding signal terminals)
As shown in Fig. 7, the signal terminals 50 are manufactured by punching 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.

Each signal terminal 50 has a first contact portion 50A that is held by the movable housing 14 and that is in electrical contact with a mating signal terminal provided in 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.

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 of the movable housing 14 and into the signal terminal insertion hole (not shown). Approximately the lower half of this first contact portion 50A is the first retaining portion 50A1 inserted (pressed) into the signal terminal insertion hole 21 of the movable housing 14. This first retaining portion 50A1 has a plurality of claw portions 54 formed in a vertical arrangement, 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, thereby retaining the first retaining portion 50A1 in the movable housing 14.

The upper half of the first contact portion 50A is the 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 that protrudes 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 comes into contact with a mating signal terminal provided on the mating connector. This results in a configuration in which the signal terminal 50 is electrically connected to the mating signal terminal.

The first connection portion 50C has a first press-in portion 50C1 inserted (pressed) into the signal terminal insertion groove 36 of the fixed housing 30 from the lower side, and a first board connection portion 50C2 extending outward in the left-right direction from the lower end of the first press-in portion 50C1, and is formed in a substantially L-shape when viewed in the front-rear direction. The first press-in portion 50C1 has 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-in portion 50C1 is held in 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-in 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 of the first board connection part 50C2 is configured to be fixed (electrically connected) to the circuit board 11 by means such as soldering.

The first elastic portion 50B constitutes the left-right middle 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 the first contact portion 50A.

(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 same. 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.

Each power 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 terminal provided on the mating connector and elastically deforms inward in the front-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.

The second contact portion 70A is formed in a long 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 the second retaining portion 70A1 inserted (pressed) into the through hole 24 of the movable housing 14. This second retaining portion 70A1 has a plurality of claw portions 72 formed in a vertical arrangement and protruding on both the left and right sides. These plurality of claw portions 72 bite into the inner circumferential surface of the through hole 24, thereby retaining the second retaining portion 70A1 to the movable housing 14.

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 further outward in the front-rear direction than the movable housing 14. The second contact portion 71 comes 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.

The second connection portion 70C has a second press-in portion 70C1 inserted (pressed) 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-in portion 70C1, and is formed in a substantially L-shape when viewed in the front-rear direction. The second press-in portion 70C1 has 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-in portion 70C1 is held in 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.

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 that is 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.

(About the movable shell)
As shown in Fig. 9, the movable shell 82 is manufactured by punching and bending a metal plate. 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.

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 parts 82B extending from both front and rear ends of the movable shell main body 82A in the front and rear directions, a pair of front and rear downward extension parts 82C extending downward from the front and rear movable side holding parts 82B, a pair of front and rear spring parts 82D extending outward in the left and right directions from the lower ends of the front and rear downward extension parts 82C, a pair of front and rear fixed side holding parts 82E extending from the ends of the front and rear spring parts 82D opposite the downward extension parts 82C, and a pair of front and rear fixed side connecting parts 82F extending from the front and rear fixed side holding parts 82E opposite the spring parts 82D.

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 front and rear ends of the movable shell body 82A outward in the front and rear direction and inward in the lateral direction, and then extend outward in the front and rear direction and upward. 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 and 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.

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 located near the top 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 roughly 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.

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 the 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.

(Regarding fixed shell)
10 , the fixed shell 92 is manufactured by punching and bending a metal plate. 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 portions 92A, 92B that cover the left and right side wall portions 30A, 30B of the fixed housing 30, a pair of front and rear connecting wall covering portions 92C, 92D that cover the front and rear connecting wall portions 30C, 30D, and a plurality of (here, four) extended wall portions 92E that are disposed on the extended wall portions 32 of the left and right side wall portions 30A, 30B of the fixed housing 30.

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 inward in the left-right direction from the upper end part of the main body wall part 93 and covers the side wall parts 30A, 30B from above, and a front wall part 98 and a rear wall part 100 that extend inward in the left-right direction from the upper part of the front end part of the main body wall part 93 and cover the side wall parts 30A, 30B from the outside in the front-rear direction. The above-mentioned main body wall part 93 corresponds to the "shield main body wall part" in this 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.

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

In addition, second covering parts (second extending parts) 114 are arranged near the outer side of each of the first covering parts 112 in the front-rear direction. Each second covering part 114 extends from the lower end of the shield body wall part 93 in the left and right side wall covering parts 92A and 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 body wall part 93 in the front-rear direction area where the power terminal 70 is arranged, 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 side wall covering parts 92A and 92B (here, side wall covering part 92A) corresponds to the "carrier cutting part" in this invention. Hereinafter, the pair of front and rear second covering parts 114 provided on the side wall covering part 92A will be referred to as the "pair of carrier cutting parts 114".

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.

The four extension walls 92E correspond to the "shield extension walls" of 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.

The base 95 of each shield extension wall portion 92E is disposed on both sides of the left and right side wall covering portions 92A, 92B in the front-rear direction. Each base 95 is plate-shaped with the plate thickness direction 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. Each base 95 has a plurality of claw portions 106 arranged in the vertical direction and protruding on both sides in the front-rear direction. These multiple claw portions 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 portion 82F of the movable shell 82 is pressed against these bases 95 from the inside in the left-right direction.

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. In addition, 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 this invention. Hereinafter, the main body wall connection part 110 is referred to as the "shield connection part 110". This shield connection part 110 connects the shield main body wall part 93 and the base part 95 of the shield extension wall part 92E.

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 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.

2, in the fixed shell 92 having the above configuration, the shield 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. In other words, the shield body wall 93, which covers the 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 from the outside in the left-right direction, is positioned offset outside in the left-right direction (opposite the movable housing 14) from the base 95 of the shield extension wall 92E. In addition, the fixed housing 30 has a recess 38 formed at a position corresponding to the base 95 and the soldering portion 96, which is recessed inward in the left-right direction, and the base 95 and the soldering portion 96 are positioned retracted inward in the left-right direction.

As described above, the fixed shell 92 of 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 connection part 110 are integrally formed by the above metal plate. As shown in FIG. 11, the shield connection part 110 has a bent part 110A that bends toward the inside in the left-right direction (the inside in the second direction), and a part 110B of the shield connection part 110 is arranged with its plate thickness direction facing the front-rear direction (the first direction). Note that the reference numerals of the bent part 110A and the part 110B are omitted except in FIG. 11.

In addition, in the resin fixed housing 30 to which the fixed shell 92 of the above 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 outside and from 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 (fractured 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, the fixed shell 92 may be configured so that the front and left shield extension wall 92E and the rear and right shield extension wall 92E are omitted, or the front and right shield extension wall 92E and the rear and left shield extension wall 92E are omitted.

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

The longitudinal middle portion of blank B is made up of sidewall covering portions 92A, 92B including shield body wall portion 93, and the longitudinal end portions are made up of connecting wall covering portions 92C, 92D, shield extension wall portion 92E, shield connection portion 110, etc. At one lateral end portion of blank B, both longitudinal end portions of shield body wall portion 93 of sidewall covering portion 92A are connected to carrier C via a pair of carrier connection portions C1 that are connected to a pair of carrier disconnect portions 114. In other words, this blank B is configured so that only the longitudinal center side at one lateral end portion is connected to carrier C via a pair of carrier connection portions C1.

The above punching process is followed by a bending process. In this bending process, the blank B is bent to form a fixed shell 92 connected to the carrier C via a pair of carrier connection parts C1. In this bending process, 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 connection part 110. This bending process is followed by a cutting process. In the cutting process, the pair of carrier connection parts C1 are cut near the shield 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.

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

In the movable connector 10 having the above 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 terminal arrangement direction X with respect to the signal terminals 50, and are bridged between the pair of side walls 30A, 30B. The middle portions of these power terminals 70 in the bridge direction Y are held at 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.

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 the movable housing 14 to move relative to the fixed housing 30. This makes it possible to absorb misalignment between the movable connector 10 and the mating connector.

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 that connects to the circuit board 11, and noise is shielded by a shell 80 that covers the housing 12. This shell 80 is composed of left and right movable shells 82 that cover the movable housing 14, and a fixed shell 92 that covers the fixed housing 30, and the above-mentioned relative displacement is allowed by the elastic deformation of the spring portion 82D of the movable shell 82.

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 that faces the movable housing 14 from the outside in the left-right direction (second direction), and an extension wall 32 that is adjacent to the main body wall 31 in the front-rear direction. The fixed shell 92 of the shell 80 has a shield main body wall 93 that covers 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 that is arranged on the extension wall 32, and a shield connection part 110 that connects the shield main body wall 93 and the shield extension wall 92E.

The above-mentioned 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 outward in the left-right direction from the base 95 and is soldered to the circuit board 11. The above-mentioned shield main body wall 93 is located outside the left-right direction from the base 95 of the shield extension wall 92E, that is, on the side where the soldering portion 96 protrudes and on the opposite side to the movable housing 14. In other words, the shield main body wall 93, which 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 of the shield extension wall 92E 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 outward in the left-right direction from the above-mentioned base 95 is arranged to be retracted inward in the left-right direction together with the base 95. This makes it easier to ensure both the movable space 34 of the movable housing 14 and the soldering strength of the fixed shell 92, even when the area occupied by the movable connector 10 on the circuit board 11 is set small.

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) of 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.

In addition, in this movable connector 10, the shield body wall 93, the shield extension wall 92E, and the shield connection part 110 are integrally formed from a metal plate. The above-mentioned shield connection part 110 has a bent part 110A that bends 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.

In addition, in this movable connector 10, the shield body wall 93 of the metal fixed shell 92 is provided with a carrier cut portion 114 that is cut from the carrier C for progressive processing. This shield body wall 93 is provided in the longitudinal middle portion of the fixed shell 92 in the planar development state. In other words, the fixed shell 92 in the planar development state is connected to the carrier C for progressive processing at the longitudinal middle portion. For this reason, the deflection of the fixed shell 92 (blank B) during progressive processing is smaller than when, for example, the fixed shell 92 in the planar development 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.

The above effects will be further explained with reference to Figures 13 and 14. In the manufacturing method of the fixed shell 92, first, in the punching process, punching including punching the outer shape is performed on a metal plate 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 Figure 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.

In addition, since only the longitudinal center side of one end of the blank B in the short direction is connected to the carrier C as described above, a crank-shaped shield connection portion 110 (bent portion) can be formed on the longitudinal end side of the blank B in the bending process. 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). In other words, 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.

<Supplementary explanation of the embodiment>
In the above embodiment, the shield connection part 110 of the fixed shell 92 has a bent part 110A that bends inward in the left-right direction (second direction), and a part 110B of the shield connection part 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 connection part 110 may have a bent part 110A that bends inward in the left-right direction (second direction), and a part 110B of the shield connection part 110 is disposed with its plate thickness direction facing the up-down direction.

In the above embodiment, each part 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 parts in the left-right direction, as in the second modified example shown in FIG. 16. In FIG. 16, DL is the dividing line of the fixed shell 92.

In addition, in the above embodiment, the configuration includes a signal terminal 50 as the first terminal and a power terminal 70 as the second terminal, but this is not limited thereto, and the second terminal may be omitted.

The present invention can be modified in various ways without departing from the spirit of the invention. It goes without saying that the scope of the invention is not limited to the above embodiment.
