Description

The present disclosure relates to a connector device.

Patent Document 1 discloses a connector device that connects a first connector and a second connector facing each other via an adapter. Both ends of the adapter are connected so that they can swing relative to the first connector and the second connector. The first connector and the second connector can be mounted on the first circuit board and the second circuit board, respectively. When the first circuit board and the second circuit board are misaligned in the direction intersecting the opposite directions, the misalignment between the first circuit board and the second circuit board is absorbed by tilting the adapter.

U.S. Pat. No. 8,801,459

The first connector has a cylindrical shield member. The outer conductor of the adapter is fitted onto the dielectric, the outer conductor and the dielectric are divided in the circumferential direction, and the outer conductor is elastically in contact with the inner peripheral surface of the shield member. At this time, since the synthetic resin dielectric is also elastically deformed, the contact pressure between the outer conductor and the shield member becomes high. As a countermeasure, it is conceivable to divide the shield member in the circumferential direction and elastically deform each divided piece. However, when the adapter is tilted, only a part of the plurality of divided pieces is elastically deformed, so that the shield member is distorted. When the shield member is distorted, the load is concentrated on only a part of the ring-shaped welded portion with the shield member on the first circuit board.

The connector device of the present disclosure has been completed based on the above circumstances, and an object of the present disclosure is to reduce the load on the circuit board and prevent it.

[Details of Embodiments of the present disclosure]
[Example 1]
The first embodiment of the connector device of the present disclosure will be described with reference to FIGS. 1 to 8. It should be noted that the present invention is not limited to these examples, and is indicated by the scope of claims, and is intended to include all modifications within the meaning and scope equivalent to the scope of claims. In the first embodiment, the front-back direction is defined as the front diagonally lower right in FIGS. 1 and 2. Regarding the vertical direction, the directions appearing in FIGS. 1 to 8 are defined as upward and downward as they are. Regarding the left-right direction, the diagonally lower left side in FIGS. 1 and 2 is defined as the left side.

As shown in FIGS. 1 and 2, the connector device of the first embodiment has a first connector A, a second connector B, and a movable terminal 50. As shown in FIGS. 3 and 4, the first connector A is mounted on the first circuit board Pa, and the second connector B is mounted on the second circuit board Pb. The first circuit board Pa is provided, for example, in an ECU (not shown) mounted on the roof of an automobile, and is arranged horizontally with the mounting surface facing upward, that is, facing the shark fin antenna side. The second circuit board Pb is provided, for example, on a shark fin antenna (not shown) attached to the roof of an automobile (not shown). The second circuit board Pb is arranged horizontally with the mounting surface facing downward, that is, facing the inside of the vehicle. The first circuit board Pa and the second circuit board Pb are arranged in a positional relationship in which both mounting surfaces are opposed to each other in parallel.

When the first circuit board Pa and the second circuit board Pb are brought close to each other, both circuit boards Pa and Pb are connected via the first connector A, the second connector B, and the movable terminal 50. Since the first circuit board Pa and the second circuit board Pb are connected without using a wire harness, high-speed communication is possible between the first circuit board Pa and the second circuit board Pb. Since the assembly tolerance between the roof and the shark fin antenna is relatively large at the mounting portion of the shark fin antenna on the roof of an automobile, the first circuit board is used in the horizontal direction intersecting the mating direction of both connectors A and B. A misalignment may occur between Pa and the second circuit board Pb. In the connector device of this embodiment, both connectors A and B can be fitted while absorbing the positional deviation of both circuit boards Pa and Pb by the swing of the movable terminal 50.

As shown in FIGS. 3 and 4, the first connector A includes a first housing 10 and a plurality of mounting terminals 14. In a state where the first connector A is mounted on the first circuit board Pa, the lower surface of the first housing 10 is fixed to the first circuit board Pa, and the lower ends of the plurality of mounting terminals 14 are printed circuits of the first circuit board Pa ( It is connected to (not shown).

The first terminal accommodating chamber 11 has a form that penetrates the first housing 10 vertically. When the first housing 10 is viewed from above, the first terminal accommodating chamber 11 has a circular shape. The plurality of first terminal accommodating chambers 11 are divided into two rows on the left and right, and three chambers are arranged in each row so as to be arranged in a row in the front-rear direction.

As shown in FIGS. 3 and 4, a plurality of mounting terminals 14 are individually housed in the plurality of first terminal storage chambers 11. As shown in FIG. 7, the mounting terminal 14 includes a mounting-side inner conductor 15, a mounting-side dielectric 18, and a mounting-side outer conductor 23. The mounting-side inner conductor 15 is a single metal component having a tubular shape whose axis is oriented in the vertical direction orthogonal to the first circuit board Pa. The mounting-side inner conductor 15 has a mounting portion 16 and a mounting-side connecting portion 17.

The mounting-side dielectric 18 is made of synthetic resin and has a cylindrical shape with the axis directed in the vertical direction. The mounting portion 16 of the mounting-side inner conductor 15 is housed in the center hole 19 of the mounting-side dielectric 18. The mounting-side connecting portion 17 of the mounting-side inner conductor 15 projects upward from the upper end surface of the mounting-side dielectric 18. On the lower end surface of the mounting-side dielectric 18 (the surface facing the first circuit board Pa), an arc-shaped projection 20 having an arc shape concentric with the mounting-side dielectric 18 is formed. The outer diameter of the arcuate protrusion 20 is set to be smaller than the outer diameter of the mounting-side dielectric 18.

The mounting-side outer conductor 23 is formed by bending a single metal plate or the like, and is a single component having a polygonal cross-section and a square cylinder shape. As shown in FIG. 7, the mounting side outer conductor 23 is a single component having a main body portion 24 and eight elastic contact pieces 32. The main body portion 24 is formed into a regular octagonal square cylinder in which eight flat plate portions 25 having the same shape are connected at an obtuse angle in the circumferential direction. A plurality of fixing portions 26 spaced apart from each other in the circumferential direction are formed on the lower end edge portion of the main body portion 24. The plurality of fixing portions 26 are fixed to the mounting surface of the first circuit board Pa by the solder S.

A plurality of protrusion-shaped press-fitting portions 27 are formed in the main body portion 24. In the first embodiment, the number of press-fitting portions 27 is half the number (four) of the number of flat plate portions 25 constituting the main body portion 24. The press-fitting portion 27 is in a form of protruding toward the outer peripheral side of the main body portion 24 by cutting up a part of the main body portion 24. As shown in FIG. 8, the press-fitting portion 27 has a locking surface 28 formed at the time of cutting and raising. The locking surface 28 faces downward, that is, in a direction facing the first circuit board Pa. The four press-fitting portions 27 are arranged in a positional relationship that is point-symmetrical in a plan view of the mounting side outer conductor 23 when viewed from above.

A plurality of biting portions 29 are formed in the main body portion 24. The bite portion 29 is in a form of protruding toward the inner peripheral side of the main body portion 24 by cutting up a part of the main body portion 24. As shown in FIG. 8, the bite portion 29 has a bite surface 30 formed at the time of cutting and raising. The bite surface 30 faces upward, that is, in the direction opposite to that of the first circuit board Pa. The press-fitting portion 27 is formed only on the flat plate portion 25 on which the press-fitting portion 27 is not formed.

The eight elastic contact pieces 32 are in the form of individually extending upward from the upper end edges of the eight flat plate portions 25 in a cantilever shape. Since the lower end edge of the elastic contact piece 32 is connected to the upper end edge of the flat region (flat plate portion 25) in the main body portion 24, the boundary line between the main body portion 24 and the elastic contact piece 32 is linear. Since the elastic contact piece 32 can elastically swing in the radial direction with the linear boundary line as a fulcrum, the spring constant of the elastic contact piece 32 is kept small.

The mounting-side outer conductor 23 is assembled with respect to the mounting-side dielectric 18 so as to surround the mounting-side dielectric 18. At the time of assembly, the mounting-side outer conductor 23 is fitted into the mounting-side dielectric 18 from above. In the state where the mounting-side outer conductor 23 and the mounting-side dielectric 18 are assembled, the biting portion 29 bites into the outer periphery of the mounting-side dielectric 18, and the biting surface 30 is locked to the outer periphery of the mounting-side dielectric 18 from below. do. As a result, the mounting-side outer conductor 23 and the mounting-side dielectric 18 are held in the assembled state.

The mounting-side dielectric 18 is surrounded by the main body 24, and the elastic contact piece 32 projects upward from the upper end surface of the mounting-side dielectric 18. The fixing portion 26 of the mounting-side outer conductor 23 projects downward from the lower end surface of the mounting-side dielectric 18, and concentrically surrounds the arc-shaped protrusions 20. Since the outer diameter of the arcuate projection 20 is smaller than the outer diameter of the mounting side dielectric 18, there is a radial direction between the inner surface of the fixing portion 26 of the mounting side outer conductor 23 and the outer peripheral surface of the arcuate projection 20. The clearance 33 is vacant. The mounting terminal 14 is configured by assembling the mounting-side inner conductor 15 and the mounting-side dielectric 18 and then assembling the mounting-side dielectric 18 and the mounting-side outer conductor 23.

The mounting terminal 14 is assembled by inserting it into the first terminal accommodating chamber 11 from below the first housing 10. In the state where the mounting terminal 14 is housed in the first terminal accommodating chamber 11, the press-fitting portion 27 is press-fitted into the inner circumference of the first terminal accommodating chamber 11, so that the mounting terminal 14 and the first housing 10 are assembled. Be retained. By locking the locking surface 28 with respect to the inner circumference of the first terminal accommodating chamber 11 from above, the mounting terminal 14 is displaced downward (on the Pa side of the first circuit board) with respect to the first housing 10. Is regulated. The mounting-side dielectric 18 is arranged at the lower end of the first terminal accommodating chamber 11. The mounting-side connecting portion 17 of the mounting-side inner conductor 15 and the elastic contact piece 32 of the mounting-side outer conductor 23 project upward from the mounting-side dielectric 18, and a plurality of elastic contact pieces 32 connect the mounting-side connecting portion 17. Siege.

The first connector A is configured by accommodating the mounting terminal 14 in the first terminal accommodating chamber 11. The first connector A is mounted on the first circuit board Pa. As shown in FIG. 8, when mounting, the lower end of the mounting portion 16 of the mounting-side inner conductor 15 is conductively fixed to the mounting surface of the first circuit board Pa by the solder S. The fixing portion 26 at the lower end of the mounting side outer conductor 23 is also fixed to the mounting surface of the first circuit board Pa by the solder S. The arcuate projection 20 protruding from the lower end surface of the mounting side dielectric 18 abuts on the mounting surface of the first circuit board Pa, but there is a radial clearance between the outer peripheral surface of the arcuate projection 20 and the inner surface of the fixing portion 26. 33 is secured. Therefore, the solder S, which is in contact with the fixed portion 26 in the molten state, is formed in the gap between the inner surface of the fixed portion 26 (mounting side outer conductor 23) and the outer peripheral surface of the arcuate projection 20 (mounting side dielectric 18) due to the capillary phenomenon. There is no risk of intrusion.

As shown in FIGS. 3 and 4, the second connector B includes a second housing 40 and the same number of mating terminals 45 as the mounting terminals 14. In a state where the second connector B is mounted on the second circuit board Pb, the upper surface of the second housing 40 is fixed to the mounting surface of the second circuit board Pb, and the upper ends of the plurality of mating terminals 45 are the second circuit board Pb. It is connected to the printed circuit (not shown). The second housing 40 is a single component made of synthetic resin having a rectangular terminal holding portion 41 and a rectangular guiding portion 42. The terminal holding portion 41 is formed with a plurality of (six in the first embodiment) second terminal accommodating chambers 43 in which the terminal holding portion 41 is vertically penetrated. The second terminal accommodating chamber 43 is a form in which the first terminal accommodating chamber 11 is turned upside down.

A plurality of mating terminals 45 are individually housed in the plurality of second terminal storage chambers 43. The mating terminal 45 is the same component as the mounting terminal 14, and is mounted in the second terminal accommodating chamber 43 in an upside-down direction with the mounting terminal 14. The guide portion 42 has a skirt-like shape protruding diagonally downward from the outer peripheral edge of the lower end of the terminal holding portion 41. The guide portion 42 is inclined so as to widen the hem downward with respect to the fitting direction of both connectors A and B. The internal space of the guide portion 42 communicates with the plurality of second terminal accommodating chambers 43 and is open to the lower side of the second housing 40. The second connector B is mounted on the mounting surface of the second circuit board Pb in the same manner as the mounting of the first connector A on the first circuit board Pa.

As shown in FIGS. 2 and 5, the movable terminal 50 has an elongated shape as a whole with its axis directed in the vertical direction (the direction in which the first circuit board Pa and the second circuit board Pb face each other). Both ends of the movable terminal 50 in the axial direction have symmetry so that they have the same shape when the movable terminal 50 is inverted. As shown in FIG. 3, the movable terminal 50 is a member formed by assembling a movable side inner conductor 51, a movable side dielectric 53, and a movable side outer conductor 57.

The movable inner conductor 51 is a metal component having an elongated shape in the vertical direction. Movable side connecting portions 52 are formed at both upper and lower ends of the movable side inner conductor 51. The movable-side dielectric 53 has a cylindrical shape coaxial with the movable-side inner conductor 51. In the insertion hole 54 of the movable side dielectric 53, the movable side inner conductor 51 is coaxially accommodated and integrally assembled. At both ends of the movable side dielectric 53 in the axial direction, circular accommodating recesses 55 are formed in which the upper and lower end surfaces of the movable side dielectric 53 are coaxially recessed. The accommodating recess 55 communicates with the insertion hole 54. The movable side connecting portion 52 is housed in the housing recess 55.

The movable side outer conductor 57 is a metal component having a cylindrical shape as a whole. The movable side outer conductor 57 is formed with a cut-up-shaped locking piece 58 protruding toward the inner peripheral side. The movable side outer conductor 57 coaxially surrounds the movable side dielectric 53. The movable side outer conductor 57 and the movable side dielectric 53 are integrated by the locking piece 58 biting into the outer periphery of the movable side dielectric 53. The lower end of the movable dielectric 53 projects downward from the lower end of the movable outer conductor 57, and the upper end of the movable dielectric 53 projects upward from the upper end of the movable outer conductor 57. The movable terminal 50 is configured by assembling the movable inner conductor 51, the movable dielectric 53, and the movable outer conductor 57.

The lower end portion (one end portion) of the movable terminal 50 is inserted into the first terminal accommodating chamber 11 and attached to the mounting terminal 14. At this time, since the lower end of the movable side dielectric 53 protrudes downward from the lower end of the movable side outer conductor 57, the interference of the movable side outer conductor 57 with respect to the upper surface of the first housing 10 and the mounting side inner conductor 15 It is possible to prevent the movable side outer conductor 57 from interfering with the upper end portion.

When the movable terminal 50 is attached to the mounting terminal 14, the elastic contact piece 32 of the mounting side outer conductor 23 elastically contacts the outer peripheral surface of the movable side outer conductor 57. In the accommodating recess 55 of the movable terminal 50, the mounting-side connecting portion 17 of the mounting-side inner conductor 15 surrounds the movable-side connecting portion 52 of the movable-side inner conductor 51 with respect to the outer peripheral surface of the movable-side inner conductor 51. Elastic contact. The movable terminal 50 can swing in the front-rear direction and the left-right direction with the mounting terminal 14 as a fulcrum.

The movable terminal 50 attached to the mounting terminal 14 has a form protruding upward from the first housing 10. The upper end of the movable terminal 50 is connected to the mating terminal 45 of the second connector B. Since one movable terminal 50 is supported in a state of being in contact with only one mounting terminal 14, the plurality of movable terminals 50 can individually swing in a direction different from that of the other movable terminals 50. There is. Therefore, as shown in FIG. 3, the plurality of movable terminals 50 can swing integrally by being penetrated through the holding hole 61 of the alignment member 60.

After the movable terminal 50 is attached to the first connector A, the first circuit board Pa and the second circuit board Pb are brought close to each other, and the upper end portion of the movable terminal 50 is connected to the mating terminal 45. The connection between the movable terminal 50 and the mating terminal 45 is performed in the same manner as the connection between the movable terminal 50 and the mounting terminal 14. Even if the first circuit board Pa and the second circuit board Pb are misaligned in the horizontal direction, the movable terminal 50 absorbs the misalignment by swinging with respect to the mounting terminal 14 and the mating terminal 45. Both connectors A and B are connected.

When the movable terminal 50 is coaxially connected to the mounting terminal 14, the amount of elastic deformation of the eight elastic contact pieces 32 is all uniform, so that the main body 24 of the mounting side outer conductor 23 has a regular octagonal shape. Does not cause distortion that breaks the. When the movable terminal 50 swings with respect to the mounting terminal 14, the amount of elastic deformation of the eight elastic contact pieces 32 of the mounting side outer conductor 23 becomes non-uniform. Therefore, the main body 24 of the outer conductor 23 on the mounting side is distorted so as to break the shape of the regular octagon, and the load is partially concentrated at the welded portion between the fixed portion 26 of the main body 24 and the first circuit board Pa. There is concern about doing so.

However, since the press-fitting portion 27 formed on the outer peripheral surface of the main body portion 24 bites into the first housing 10 made of synthetic resin, the deformation of the main body portion 24 is prevented. Further, the deformation of the main body 24 is also prevented by the biting portion 29 formed on the inner peripheral surface of the main body 24 biting into the mounting side dielectric 18. Therefore, even if the movable terminal 50 swings with respect to the mounting terminal 14 and the amount of elastic deformation of the eight elastic contact pieces 32 becomes non-uniform, there is a possibility that the main body 24 will be distorted so as to lose the shape of a regular octagon. No. Therefore, there is no possibility that stress is locally concentrated at the welded portion between the fixing portion 26 and the first circuit board Pa.

The connector device of the first embodiment has a first housing 10 made of synthetic resin mounted on the first circuit board Pa, and a mounting terminal 14 connected to the first circuit board Pa while being housed in the first housing 10. And a movable terminal 50 that can swing around the mounting terminal 14 as a fulcrum. The mounting terminal 14 has a mounting side outer conductor 23. The mounting-side outer conductor 23 has a cylindrical main body portion 24, a fixing portion 26, a plurality of elastic contact pieces 32, and a press-fitting portion 27. The fixing portion 26 is integrally formed at the end edge portion (lower end edge portion) on the base end side of the main body portion 24, and is fixed to the first circuit board Pa. The plurality of elastic contact pieces 32 are integrally formed at the end edge portion (upper end edge portion) on the tip end side of the main body portion 24, and elastically contact the movable side outer conductor 57 of the movable terminal 50. The press-fitting portion 27 is formed in the main body portion 24 and is fixed to the first housing 10 in a press-fitting state.

In the connector device of the first embodiment, there is a concern that the cylindrical main body 24 may be distorted when the movable terminal 50 swings and the amount of elastic deformation of the plurality of elastic contact pieces 32 becomes non-uniform. .. However, since the press-fitting portion 27 formed in the main body portion 24 is fixed to the first housing 10 made of synthetic resin in a press-fitting state, the distortion of the main body portion 24 is suppressed. As a result, the load acting on the portion of the first circuit board Pa that is fixed to the main body portion 24 becomes uniform over the entire circumference of the main body portion 24. Therefore, the connector device of the first embodiment can reduce the load on the first circuit board Pa.

The main body portion 24 has a polygonal shape in which a plurality of flat plate portions 25 are connected in the circumferential direction. The plurality of elastic contact pieces 32 individually extend from the plurality of flat plate portions 25. As a result, the base end portion (the portion connected to the flat plate portion 25) of the elastic contact piece 32 is formed in a flat plate shape, so that the spring constant of the elastic contact piece 32 can be reduced. As a result, when the elastic contact piece 32 is elastically deformed, the stress generated in the main body portion 24 is reduced, so that the distortion of the main body portion 24 can be further suppressed.

The plurality of press-fitting portions 27 are arranged so as to be rotationally symmetric. Specifically, the four press-fitting portions 27 are formed in the four flat plate portions 25 arranged every other in the circumferential direction among the eight flat plate portions 25. According to this configuration, the distortion of the main body 24 can be effectively suppressed.

The mounting terminal 14 has a mounting-side dielectric 18 surrounded by a mounting-side outer conductor 23. The main body 24 of the mounting-side outer conductor 23 is formed with a biting portion 29 that is fixed to the mounting-side dielectric 18 in a biting state. Therefore, the distortion of the main body 24 can be suppressed by biting into the mounting-side dielectric 18.

The fixing portion 26 is fixed to the first circuit board Pa by the solder S. A clearance 33 is provided between the inner peripheral surface of the fixing portion 26 and the outer peripheral surface of the end portion (arc-shaped protrusion 20) on the base end side of the mounting-side dielectric 18. According to this configuration, it is possible to prevent the molten solder S from entering the gap between the inner peripheral surface of the main body 24 and the arcuate projection 20 (the outer peripheral surface of the mounting-side dielectric 18) due to the capillary phenomenon.
