[0003] [Patent Document 1] JP 2005-347191 A Summary of the Invention [Problem to be solved by the invention]

[0004] The front end region of the square tube portion is an area where metal parts are concentrated because not only the elastic contact pieces are present but also the tab portion is inserted. The crimped portion is also an area where metal parts are concentrated because a core wire of an electric wire having an outer diameter larger than the plate thickness of the crimped portion is connected. The front end region of the square tube portion where metal parts are concentrated and the crimped portion have a relatively low impedance. In contrast, the rear end region of the square tube portion has few metal parts and a relatively high impedance because there are no elastic contact pieces and the tab portion is not inserted. Thus, conventional shielded connectors have a problem in that it is difficult to match the impedance of the female inner conductor terminal.

[0005] The shielded connector of the present disclosure was developed based on the above circumstances, and has an object to reduce impedance mismatch. [Means for solving the problem]

[0006] The shielded connector of the present disclosure comprises: a dielectric body having a plurality of chambers separated in a width direction by partitions; a plurality of inner conductors each having an elongated shape in a front-rear direction and individually accommodated in the plurality of accommodation chambers in a parallel state; The partition has an opening for providing an air layer between the adjacent storage chambers via the partition. Effect of the Invention

[0007] According to the present disclosure, impedance mismatch can be mitigated. [Brief description of the drawings]

[0009] [Description of the embodiments of the present disclosure] First, embodiments of the present disclosure will be listed and described. The shielded connector of the present disclosure comprises: (1) A dielectric body having a plurality of chambers separated in the width direction by a partition wall, and a plurality of inner conductors each having an elongated shape in the front-rear direction and individually accommodated in the plurality of chambers in a parallel state, the partition wall being formed with an opening for interposing an air layer between the adjacent chambers via the partition wall. According to the configuration of the present disclosure, in a region of a transmission line constituted by the inner conductor where an opening is formed in the length direction of the inner conductor, impedance is increased by the air layer of the opening. By arranging the opening in accordance with a region of the inner conductor where metal parts are concentrated, it is possible to reduce impedance mismatch of the transmission line constituted by the inner conductor.

[0010] (2) The inner conductor is made of a metal plate material, and a rectangular tube portion is formed at the front end portion in the longitudinal direction of the inner conductor, into which a tab of a mating inner conductor is inserted, and a resilient contact piece that resiliently contacts the tab is housed in the rectangular tube portion, and the formation region of the opening in the longitudinal direction of the inner conductor preferably includes at least a part of the formation region of the resilient contact piece. According to this configuration, the region in which the resilient contact piece is housed is a region in which not only the metallic resilient contact piece but also the four metallic plate portions and metallic tabs that constitute the rectangular tube portion are concentrated and arranged, so that there is a concern that the impedance will be low. However, in the longitudinal direction of the inner conductor, an air layer of the opening exists in the formation region of the resilient contact piece, and this air layer is arranged so as to be adjacent to the formation region of the resilient contact piece. This makes it possible to increase the impedance of the formation region of the resilient contact piece in the transmission line constituted by the inner conductor.

[0011] (3) The inner conductor is preferably made of a metal plate, a crimped portion is formed at a rear end in the longitudinal direction of the inner conductor to be crimped to the core wire of the electric wire, and the region in the longitudinal direction of the inner conductor where the opening is formed includes at least a part of the region in which the crimped portion is formed. According to this configuration, in the region in which the crimped portion is formed, in addition to the metal crimped portion, core wires having a diameter larger than the plate thickness dimension of the crimped portion are concentrated and arranged, so that there is a concern that the impedance will be low. However, in the longitudinal direction of the inner conductor, an air layer of the opening exists in the region in which the crimped portion is formed, and this air layer is arranged so as to be adjacent to the crimped portion. This makes it possible to increase the impedance at the crimped portion in the transmission line formed by the inner conductor.

[0012] (4) It is preferable that the dielectric body is configured with a pair of cases joined together in a direction perpendicular to both the parallel direction of the inner conductors and the longitudinal direction of the inner conductors, the pair of cases are formed with a pair of wall components that protrude opposite to each other to form the partition, and the opening is formed between the wall component formed in one of the cases and the wall component formed in the other case. With this configuration, even if the opening has a shape that does not open to the outer surface of the dielectric body, it is possible to mold the opening by molding.

[0013] (5) It is preferable that the opening is open to the outer surface of the dielectric body. According to this configuration, a larger volume of the opening can be ensured compared to a case where the opening area of ​​the opening is limited to a range facing the accommodation chamber, and therefore, it is excellent in the effect of increasing impedance.

[0014] (6) It is preferable that the opening is open over the entire region in the height direction of the accommodating chamber, and that the portions of the partition wall sandwiching the opening from the front and rear are present over the entire region in the height direction of the accommodating chamber. With this configuration, it is possible to restrict the displacement of the partition wall in the width direction on both the front and rear sides of the opening, and to position the inner conductor accommodated in the accommodating chamber in the width direction.

[0015] [Details of the embodiment of the present disclosure] [Example 1] A first embodiment of the present disclosure will be described with reference to Figs. 1 to 6. The present invention is not limited to these examples, but is indicated by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims. In this first embodiment, the left in Figs. 1 and 2, the diagonally upper left in Fig. 5, and the diagonally lower left in Fig. 6 are defined as the front with respect to the front-rear direction. The directions shown in Figs. 1 to 6 are defined as the upper and lower directions. The directions shown in Figs. 3 and 4 are defined as the left and right directions.

[0016] As shown in Fig. 1, the shielded connector of the first embodiment includes a housing 10 and a shield terminal 20 fixed to a front end of a shielded electric wire 11. The shield terminal 20 is accommodated in the housing 10 made of synthetic resin. The shielded electric wire 11 is an STP (Shielded Twisted Pair) cable, and includes two covered electric wires 12, a shield layer 15 made of a braided wire, and a sheath 16. The front ends of the two covered electric wires 12 extend forward from the front end of the sheath 16. The front end of the shield layer 15 is folded back backward to surround the outer circumferential surface of the sheath 16.

[0017] The shield terminal 20 is configured by assembling a pair of inner conductors 21, a dielectric 40 that houses the pair of inner conductors 21, and an outer conductor 35 that surrounds the dielectric 40. The inner conductor 21 is formed into a shape elongated in the front-rear direction by bending a metal plate material. A square tube portion 22 is formed in a portion from the front end of the inner conductor 21 to the center of the inner conductor 21 in the front-rear direction. As shown in Figs. 2 and 3, the square tube portion 22 has a lower plate portion 23, a pair of left and right side plate portions 24 extending upward from both left and right side edges of the lower plate portion 23, and an upper plate portion 25. The upper plate portion 25 is configured by an inner plate portion 26 extending from the upper end edge of one side plate portion 24, and an outer plate portion 27 extending from the upper end edge of the other side plate portion 24 and overlapping the outer surface of the inner plate portion 26.

[0018] A resilient contact piece 28 is housed within the rectangular tube portion 22. The resilient contact piece 28 is formed by folding back a strip-shaped portion extending from the front edge of the inner plate portion 26. The resilient contact piece 28 has a mountain shape in side view. As shown in Fig. 2, a tab 65 of a mating inner conductor (not shown) is inserted into the rectangular tube portion 22. The resilient contact piece 28 resiliently contacts the inserted tab 65.

[0019] The crimping portion 29 of the inner conductor 21 extends rearward from the rear end of the rectangular tube portion 22. The crimping portion 29 has an open-barrel-shaped wire barrel portion 30 and an open-barrel-shaped insulation barrel portion 31. The wire barrel portion 30 is Covered Wire 12 The insulation barrel portion 31 is crimped onto the outer peripheral surface of the insulating coating 14 of the insulated electric wire 12.

[0020] The outer conductor 35 is formed by assembling a crimping member 37 to a rectangular cylindrical shielding member 36. The shielding member 36 is assembled to the dielectric 40 in a state in which it surrounds the entire outer circumferential surface of the dielectric 40. The crimping member 37 is connected to the front end of the shielding layer 15 by crimping.

[0021] The front end of the shielded wire 11 is connected to the rear end of the shield terminal 20 by fixing the covered wire 12 to the inner conductor 21 and fixing the outer conductor 35 to the shield layer 15. The shielded wire 11 and the shield terminal 20 form a differential transmission line for high-speed communication.

[0022] The dielectric 40 is made of synthetic resin, and is configured by combining an upper case 41 and a lower case 42 vertically as shown in Figs. 1 to 4. When the upper case 41 and the lower case 42 are combined as shown in Figs. 3 and 4, a pair of left and right storage chambers 44 partitioned by a partition wall 43 are formed inside the dielectric 40. The inner conductor 21 is accommodated in the storage chamber 44.

[0023] As shown in Fig. 5, the upper case 41 is a single part having an upper wall portion 45, a front wall portion 46, a pair of upper front sidewall portions 47, a pair of upper rear sidewall portions 48, and an upper sidewall forming portion 49. A pair of left and right insertion holes 50 are formed in the front wall portion 46. The upper front sidewall portions 47 protrude downward from front ends of both left and right side edges of the upper wall portion 45. The upper front sidewall portions 47 are connected to the front wall portion 46. The upper rear sidewall portions 48 protrude downward from positions near the rear ends of both left and right side edges of the upper wall portion 45.

[0024] The upper side wall component 49 has a front partition 51 and a rear partition 52 extending in the front-rear direction. The front partition 51 protrudes downward from the front end of the upper wall 45 at the center in the left-right direction. The front partition 51 is connected to the front wall 46. The rear partition 52 is disposed rearward of the front partition 51 and protrudes downward from the center in the left-right direction of the upper wall 45. The space between the rear end edge of the front partition 51 and the front end edge of the rear partition 52 functions as a front opening 53. The upper end of the front opening 53 opens to the upper surface (outer surface) of the upper wall 45. The rear partition 52 has a notch 54 formed by recessing the lower end edge of the rear partition 52 upward in a trapezoidal shape. A positioning recess 55 is formed on the lower end surface of the front partition 51 and the lower end surface of the front end of the rear partition 52.

[0025] 6, the lower case 42 is a single part having a bottom wall portion 56, a pair of left and right lower sidewall portions 57, a positioning rib 58, and a lower sidewall component portion 59. The pair of lower sidewall portions 57 are disposed rearward of the center of the bottom wall portion 56 in the front-rear direction and protrude upward from both left and right side edges of the bottom wall portion 56. The positioning rib 58 protrudes upward from the center of the bottom wall portion 56 in the front-rear direction and has an elongated shape extending in the front-rear direction. The range in which the positioning rib 58 is formed in the front-rear direction is the region from the front end of the bottom wall portion 56 to the center of the bottom wall portion 56 in the front-rear direction.

[0026] The lower sidewall component 59 extends in an elongated manner in the front-rear direction and rises upward from the center of the bottom wall 56 in the left-right direction. The front end of the lower sidewall component 59 and the rear end of the positioning rib 58 are connected. The range of the lower sidewall component 59 in the front-rear direction is a region from the center of the bottom wall 56 in the front-rear direction to a position forward of the rear end of the bottom wall 56. In the front-rear direction, the range of the lower sidewall component 59 is the same as the range of the notch 54 of the upper sidewall component 49. In the left-right direction, the range of the lower sidewall component 59 is the same as the range of the notch 54 of the upper sidewall component 49. In a side view of the dielectric 40 parallel to the arrangement direction of the accommodation chambers 44, the lower sidewall component 59 has a trapezoid shape similar to that of the notch 54.

[0027] In a state where the upper case 41 and the lower case 42 are combined and the dielectric 40 is assembled, the top wall 45 and the bottom wall 56 face each other in parallel, and the upper front side wall 47, the upper rear side wall 48, and the lower side wall 57 form the left and right outer walls of the dielectric 40. The lower end surface of the front partition 51 faces the top surface of the bottom wall 56 in a state close to or in contact with it. Rear partition 52 The lower end faces of the portions forward and rearward of the cutout portion 54 face the upper surface of the bottom wall portion 56 in a state close to or in contact with the upper surface of the bottom wall portion 56. The lower side-wall component 59 is housed in the cutout portion 54 of the upper side-wall component 49. The positioning recesses 55 of the front partition portion 51 and the rear partition portion 52 fit into the positioning rib 58.

[0028] The upper side-wall component 49 and the lower side-wall component 59 form a partition 43 that separates the pair of storage chambers 44. The partition 43 is formed in an area extending from the front end of the front partition 51 to the rear end of the rear partition 52. A front opening 53 and a rear opening 60 that communicate between the pair of storage chambers 44 are provided within the area in which the partition 43 is formed. The rear opening 60 is located at a position rearward of the front opening 53. The front opening 53 and the rear opening 60 are spaces for ensuring an air layer between the pair of storage chambers 44.

[0029] The front opening 53 is a space formed in the upper sidewall component 49. In a side view of the shield terminal 20 seen from the direction in which the pair of accommodating chambers 44 are aligned, the opening shape of the front opening 53 is rectangular. The opening range in the height direction of the front opening 53 in the accommodating chamber 44 extends over a range larger than the total height region of the partition wall portion 43 and the accommodating chamber 44. Since the upper end of the front opening 53 opens to the outer surface of the dielectric 40, the height of the air layer formed by the front opening 53 is higher than the opening height of the front opening 53 in the accommodating chamber 44.

[0030] 2, the front-rear opening range of the front opening 53 (range where an air layer exists) includes the square tube portion 22 and the elastic contact piece 28 of the inner conductor 21, and a part of the area where the tab 65 to be inserted into the square tube portion 22 exists. The height opening range of the front opening 53 (range where an air layer exists) extends beyond the entire height range of the square tube portion 22 in both the up and down directions.

[0031] Of the transmission line formed by the inner conductor 21, the region in which the elastic contact piece 28 and tab 65 are housed within the rectangular tube portion 22 is a metal concentrated region in which multiple metal members are arranged in close proximity, and so there is concern that the impedance may become low. However, since an air layer secured by the front opening 53 is present between the two metal concentrated regions, the impedance does not become too low.

[0032] The rear opening 60 is a slit-like space formed between the trapezoidal notch 54 of the upper sidewall constituent part 49 and the trapezoidal upper edge part of the lower sidewall constituent part 59. In a side view, the rear opening 60 has a shape that is bent along the upper base and a pair of legs of the trapezoid. The opening area of ​​the rear opening 60 in the accommodation chamber 44 is smaller than the opening area of ​​the front opening 53 in the accommodation chamber 44.

[0033] 2, the opening range (air layer presence range) of the rear opening 60 in the front-rear direction is set to an area including a portion where the wire barrel portion 30 of the crimping portion 29 and the core wire 13 of the shielded electric wire 11 are connected by crimping. The opening range (air layer presence range) of the rear opening 60 in the height direction is set to an area including a portion where the wire barrel portion 30 and the core wire 13 are connected.

[0034] In the transmission line formed by the inner conductor 21, the region where the wire barrel portion 30 and the core wire 13 are connected is a metal concentrated region where multiple metal members are arranged close to each other, and so there is a concern that the impedance may become low. However, since an air layer secured by the rear opening 60 is present between the two metal concentrated regions, the impedance does not become too low.

[0035] The connection region between the wire barrel portion 30 and the core wire 13 has a smaller amount of metal than the region in which the elastic contact piece 28 and the tab 65 are housed within the rectangular tube portion 22, so the opening area of ​​the rear opening 60 is set smaller than the opening area of ​​the front opening 53. In this way, the impedance of the region of the transmission line where the concentration of metal members is high is increased by the air layer secured by the front opening 53 and the rear opening 60. This keeps the difference in impedance with the region where the concentration of metal is low low, and achieves impedance matching.

[0036] The shielded connector of the first embodiment includes a dielectric 40 and a plurality of inner conductors 21. The dielectric 40 has a plurality of accommodating chambers 44 partitioned in the width direction by a partition portion 43. The inner conductor 21 has an elongated shape in the front-rear direction. The plurality of inner conductors 21 are individually accommodated in the plurality of accommodating chambers 44 in a parallel state. A front opening 53 and a rear opening 60 are formed in the partition portion 43. The front opening 53 and the rear opening 60 are spaces for providing an air layer between adjacent accommodating chambers 44 via the partition portion 43.

[0037] According to this configuration, in the region of the transmission line formed by the inner conductor 21 where the front opening 53 is formed and the region where the rear opening 60 is formed in the longitudinal direction of the inner conductor 21, the impedance is increased by the air layers of the front opening 53 and the rear opening 60. Since the front opening 53 and the rear opening 60 are arranged in accordance with the region of the inner conductor 21 where metal portions are concentrated, it is possible to alleviate impedance mismatch of the transmission line formed by the inner conductor 21.

[0038] The inner conductor 21 is made of a metal plate material. At the front end in the longitudinal direction of the inner conductor 21, a square tube portion 22 is formed into which a tab 65 of a mating inner conductor (not shown) is inserted. A resilient contact piece 28 that resiliently contacts the tab 65 is accommodated in the square tube portion 22. In the region in which the resilient contact piece 28 is accommodated, in addition to the metallic resilient contact piece 28, the four metallic plate portions 23 to 27 constituting the square tube portion 22 and the metallic tab 65 are concentrated and arranged, so that there is a concern that the impedance will be low. As a countermeasure, the formation region of the front opening 53 is set to include at least a part of the formation region of the resilient contact piece 28 in the longitudinal direction of the inner conductor 21. In the formation region of the resilient contact piece 28 in the longitudinal direction of the inner conductor 21, an air layer of the front opening 53 exists in the formation region of the resilient contact piece 28, and this air layer is arranged so as to be adjacent to the formation region of the resilient contact piece 28. This makes it possible to increase the impedance of the formation region of the resilient contact piece 28 in the transmission line constituted by the inner conductor 21.

[0039] A crimping portion 29 is formed at the rear end in the length direction of the inner conductor 21 to be crimped to the core wire 13 of the coated electric wire 12. In the region where the crimping portion 29 is formed, in addition to the metal crimping portion 29, the core wires 13 having a diameter larger than the plate thickness dimension of the crimping portion 29 are concentrated and arranged, so that there is a concern that the impedance will be low. As a countermeasure, the formation region of the rear opening 60 is set to include at least a part of the formation region of the crimping portion 29 in the length direction of the inner conductor 21. In the formation region of the crimping portion 29 in the length direction of the inner conductor 21, an air layer of the rear opening 60 exists in the formation region of the crimping portion 29, and this air layer is arranged so as to be adjacent to the crimping portion 29. This makes it possible to increase the impedance of the crimping portion 29 in the transmission line formed by the inner conductor 21.

[0040] The dielectric 40 is configured with an upper case 41 and a lower case 42 that are combined in the vertical direction. The combination direction of the upper case 41 and the lower case 42 is perpendicular to both the direction in which the pair of inner conductors 21 are arranged side by side and the longitudinal direction of the inner conductor 21. An upper side wall component 49 is formed in the upper case 41, and a lower side wall component 59 is formed in the lower case 42. The upper side wall component 49 and the lower side wall component 59 protrude to face each other and form the partition wall 43. The rear opening 60 is formed between the upper side wall component 49 formed in the upper case 41 and the lower side wall component 59 formed in the lower case 42. The rear opening 60 is shaped so as not to open to the outer surface of the dielectric 40, but the rear opening 60 can be molded by a die.

[0041] Front opening 53 opens to the outer surface of dielectric 40. According to this configuration, a larger volume of front opening 53 is ensured compared to a case where the opening area of ​​front opening 53 is limited to a range facing accommodation chamber 44, and therefore, it is excellent in the effect of increasing impedance.

[0042] The front opening 53 is open over the entire height direction of the accommodating chamber 44. The portions of the partition 43 that sandwich the front opening 53 from the front and rear, i.e., the front end of the rear partition 52 and the front partition 51, exist over the entire height direction of the accommodating chamber 44. With this configuration, the displacement of the partition 43 in the width direction can be restricted on both the front and rear sides of the front opening 53, and the inner conductor 21 accommodated in the accommodating chamber 44 can be positioned in the width direction.

[0043] [Other Examples] The present invention is not limited to the embodiments described above and shown in the drawings, but is indicated by the claims. The present invention includes the equivalent meaning of the claims and all modifications within the scope of the claims, and is intended to include the following embodiments. In the above embodiment 1, the dielectric is formed by combining a pair of cases, but the dielectric may be a single part. In this case, the opening can be molded by molding if it is shaped to open on the outer surface of the dielectric. In the above embodiment, two openings are formed in one partition, but the number of openings may be one, or three or more. [Explanation of symbols]
