[0010] The connector disclosed herein comprises:

[0011] a housing having terminal receiving chambers arranged in two rows;

[0012] two short-circuit members, the two short-circuit members being mounted in the plurality of terminal receiving chambers arranged in one row and the plurality of terminal receiving chambers arranged in another row to form a differential pair;

[0013] a plurality of terminal parts, each of which is individually fixed to the trunk line and the branch line constituting the differential pair and is connected to the short-circuit member by being inserted into the terminal receiving chamber; and

[0014] A plurality of lances are formed on the housing and prevent the terminal parts inserted into the terminal receiving chamber from falling out.

[0015] The lance is arranged only in a region different from a region sandwiched between the plurality of terminal accommodating chambers arranged in the one row and the plurality of terminal accommodating chambers arranged in the other row.

[0026] [Description of Embodiments of the Present Disclosure]

[0027] First, embodiments of the present disclosure will be described below.

[0028] The connector of the present disclosure,

[0029] (1) has: a housing having terminal housing chambers arranged in two rows; two short-circuit members, the two short-circuit members are assembled to a plurality of terminal housing chambers arranged in one column and a plurality of terminal housing chambers arranged in the other column and constitute a differential pair; a plurality of terminal parts, the plurality of terminal parts are individually fixed to a trunk line constituting a differential pair and a branch line constituting a differential pair, and are connected with the short-circuit members by being inserted into the terminal housing chambers; and a plurality of lance-shaped parts, the plurality of lance-shaped parts are formed on the housing and prevent the terminal parts inserted into the terminal housing chambers from being detached, the lance-shaped parts are arranged only in a region different from the region sandwiched by the plurality of terminal housing chambers arranged in the one column and the plurality of terminal housing chambers arranged in the other column

[0030] According to the configuration of the present disclosure, a circuit constituted by a short-circuit member and a terminal part housed in a plurality of terminal housing chambers arranged in one column and a circuit constituted by a short-circuit member and a terminal part housed in a plurality of terminal housing chambers arranged in the other column constitute a differential pair. Since the lance-shaped parts are not arranged between the plurality of terminal housing chambers arranged in one column and the plurality of terminal housing chambers arranged in the other column, the interval of the differential pair in the housing can be made sufficiently close. Thus, the design freedom in setting the interval of the differential pair in the housing is improved, so the impedance in the housing and the impedance of the trunk line and the branch line outside the housing can be matched with high precision.

[0031] (2) Preferably, in each column of the terminal housing chambers, the plurality of terminal housing chambers and the plurality of lance-shaped parts are alternately arranged. According to this configuration, since the space for forming the lance-shaped parts falls within the column of the terminal housing chambers, the housing can be miniaturized in the arrangement direction of the short-circuit members.

[0032] (3) In (2), preferably, in the front surface of the housing, a connection port communicating with the terminal housing chambers and an operation port through which the lance-shaped parts are detached from the terminal parts are opened in an alternately arranged manner, the short-circuit member has a plurality of connection portions inserted into the terminal housing chambers from the connection port to connect with the terminal parts and a linking portion linking the plurality of connection portions with each other, and the linking portion is arranged at a position different from the operation port when the housing is viewed from the front. According to this configuration, even if the connection ports of the terminal housing chambers and the operation ports for the lance-shaped parts are arranged in one column, as long as the linking portion does not interfere with the work of inserting a jig into the operation port to displace the lance-shaped part when the work is performed.

[0033] (4) In (3), preferably, the short-circuit member is formed with a reinforcing portion, the reinforcing portion is in a form in which the connection portion is elongated and protrudes in a rib shape from the linking portion. According to this configuration, deformation of the connection portion can be prevented by the reinforcing portion.

[0034] (5) In (3) or (4), preferably, the connecting portions of the two short-circuit members are arranged so as to sandwich the terminal storage chambers when viewed from the front. According to this configuration, no connecting portion is arranged between the terminal storage chambers of one row and the terminal storage chambers of the other row, so the spacing between the differential pair circuits in the housing can be made sufficiently close. As a result, the design freedom when setting the spacing between the branch circuits constituting the differential pair in the housing is increased, so that the impedance inside the housing and the impedance of the main line and branch line outside the housing can be matched with high precision.

[0035] (6) Preferably, the distance between the terminal parts inserted into the terminal receiving chambers arranged in the first row and the terminal parts inserted into the terminal receiving chambers arranged in the second row is 2.1 mm to 2.3 mm. This configuration allows the impedance inside the housing to be matched with the impedance of the trunk line and branch line outside the housing with high precision.

[0036] (7) In (6), preferably, the distance between the terminal parts inserted into the terminal receiving chambers arranged in the first row and the terminal parts inserted into the terminal receiving chambers arranged in the second row is 2.2 mm. This configuration allows the impedance inside the housing to be matched with the impedance of the trunk line and branch line outside the housing with higher accuracy.

[0037] [Details of the embodiments of the present disclosure]

[0038] [Example 1]

[0039] Reference Figures 1-7 The present invention is not limited to these examples, but is intended to include all changes within the meaning and scope equivalent to the claims. In this embodiment 1, regarding the front and rear directions, Figure 1 、 2 The lower left corner and Figure 3 The left direction in is defined as the front. Figures 1-6 The directions shown are defined as upward and downward. Figure 1 、 2 The directions shown in 4 to 6 are defined as left and right as they are.

[0040] The connector A of this embodiment is used for a high-speed communication circuit 50 mounted on a vehicle. Figure 7As shown, a high-speed communication circuit 50 includes a trunk line 51 and multiple branch lines 52 branching off from the trunk line 51 via multi-drop connections at various locations. Connector A in this embodiment serves as a connection device for branching the branch lines 52 from the trunk line 51. Both the trunk line 51 and the branch lines 52 are comprised of differential pairs. The trunk line 51 is cut at various locations where the branch lines 52 branch, resulting in multiple connection ends 51E. The connection ends 51E of the trunk line 51 and the base ends 52E of the branch lines 52 are connected via connector A.

[0041] like Figure 2 As shown, the connector A comprises a housing 10, a pair of short-circuit members 30, and a plurality (three pairs) of terminal parts 40. Figure 3 As shown, three pairs of terminal storage chambers 11 are formed in the housing 10 so as to penetrate the housing 10 in the front-to-back direction. Figure 5 As shown, three pairs of terminal storage chambers 11 are arranged in two left and right rows. In each left and right row, three terminal storage chambers 11 are arranged vertically. The front ends of the terminal storage chambers 11 are opened as connection ports 12 on the front surface 10F of the housing 10.

[0042] like Figure 3 As shown, the housing 10 is formed with a lance 13, which is used to prevent the terminal component 40 inserted into the terminal receiving chamber 11 from falling out. The lance 13 is in a cantilevered shape extending forward along the lower surface of the terminal receiving chamber 11 and is elastically displaceable in the vertical direction. The housing 10 has a demolding space 14 formed when the lance 13 is molded. The demolding space 14 is arranged in front of the lance 13. The front end of the demolding space 14 opens into the front surface 10F of the housing 10 as an operation port 15.

[0043] like Figure 5 As shown, in the left area of ​​the front surface 10F of the shell 10, three connection ports 12 and three operation ports 15 are arranged in a row in a manner that is alternately arranged in the vertical direction. In the right area of ​​the front surface 10F of the shell 10, three connection ports 12 and three operation ports 15 are also arranged in a row in a manner that is alternately arranged in the vertical direction. The connection port 12 is arranged at the top end of each column, and the operation port 15 is arranged at the bottom end of each column. The width dimension of the operation port 15 is larger than the width dimension of the connection port 12. When the shell 10 is viewed from the front, the connection port 12 is arranged within the full width of the operation port 15.

[0044] A pair of symmetrical housing recesses 20 are formed on the front surface 10F of the housing 10 to accommodate two short-circuit components 30. The housing recesses 20 include a connecting recess 21 formed in the shape of a vertically elongated slit, and three branch recesses 22 formed in the shape of slits elongated in the horizontal direction. The connecting recess 21 and the three branch recesses 22 communicate with each other. The housing recesses 20 house the short-circuit components 30 mounted in the housing 10.

[0045] The connecting recess 21 is a slender shape extending in a direction parallel to the arrangement direction of the terminal storage chambers 11 in the left and right columns and the arrangement direction of the connection ports 12 and the operating ports 15 in the left and right columns. The two connecting recesses 21 spaced apart on the left and right are arranged in a manner that clamps the connection port 12 and the operating port 15 from the left and right sides. In other words, the connecting recess 21 is arranged in an area slender in the vertical direction between the connection port 12 and the operating port 15 and the left and right side edges of the housing 10. The formation range of the connecting recess 21 in the vertical direction is the range from the same height as the uppermost connection port 12 to the same height as the lowermost connection port 12.

[0046] The three branch recesses 22 extend in a manner that branches left and right from the connecting recess 21 toward the area where the connection port 12 and the operating port 15 are located. The three branch recesses 22 are arranged at the same height as the three connection ports 12 arranged vertically. The extended end of each branch recess 22 communicates with the connection port 12. In other words, the connection port 12 opens at the extended end of the branch recess 22.

[0047] The short-circuit member 30 is a single component made of a conductive material such as metal. Figure 2 As shown, the short-circuit member 30 includes a connecting portion 31, three connecting portions 32, and three reinforcing portions 35. The connecting portion 31 is formed into a flat plate with the plate thickness direction oriented in the left-right direction. The shape of the connecting portion 31 when viewed from the side of the housing 10 is a vertically elongated rectangle. The vertical dimension (height dimension) of the connecting portion 31 is the same as the vertical dimension of the connecting recess 21 of the housing 10. The horizontal dimension (thickness dimension) of the connecting portion 31 is the same as the horizontal dimension (width dimension) of the connecting recess 21.

[0048] The three connecting portions 32 are connected to the rear edge of the connecting portion 31 at three locations: the uppermost end, the lowermost end, and the vertical center. The three connecting portions 32, arranged vertically side by side, are electrically connected to each other via the connecting portion 31. The connecting portion 32 includes a partitioning connecting portion 33 that protrudes from the rear edge of the connecting portion 31 in the horizontal direction (the thickness direction of the connecting portion 31), and a connecting function portion 34 that extends rearward in a cantilevered manner from the protruding end of the partitioning connecting portion 33.

[0049] The vertical dimension of the partitioning connection portion 33 is the same as the vertical dimension of the branch recess 22. The horizontal projection of the partitioning connection portion 33 is the same as the horizontal length of the branch recess 22. The vertical dimension of the functional connection portion 34 is the same as the vertical dimension of the connection port 12. The horizontal dimension of the functional connection portion 34 is the same as the horizontal dimension of the connection port 12.

[0050] In a front view, the connecting portion 31 and the three vertically aligned connecting functional portions 34 are positioned so as to be spaced apart in the horizontal direction. The short-circuit member 30 mounted in the left-side housing recess 20 has the connecting portion 31 positioned to the left of the connecting functional portion 34. The short-circuit member 30 mounted in the right-side housing recess 20 has the connecting portion 31 positioned to the right of the connecting functional portion 34.

[0051] The three reinforcements 35 are connected to the connecting portion 31 and are separately connected to the three connecting portions 32. The reinforcements 35 are formed into a flat plate with the plate thickness oriented in the vertical direction. When viewed from above, the reinforcements 35 are rectangular and elongated in the front-to-back direction. The three reinforcements 35 protrude in a cantilevered manner from the side surfaces of the connecting portion 31 at three locations: the top and bottom ends, and the vertical center. The reinforcements 35 extend from the front to the rear of the connecting portion 31 in the front-to-back direction.

[0052] The rear end edge of the reinforcement portion 35 is connected to the front edge of the partitioning connection portion 33 of the connection portion 32. The reinforcement portion 35 and the partitioning connection portion 33 are integrated, with the connection function portion 34 extending from the rear end edge of the reinforcement portion 35. In other words, the reinforcement portion 35, which protrudes like a rib from the connecting portion 31, is connected to the front extension line of the connection function portion 34. Because the connection function portion 34 and the reinforcement portion 35 are connected in the front-to-back direction, the front end of the connection function portion 34 is reinforced.

[0053] The short-circuit member 30 is assembled to the housing 10 while housed in the housing recess 20. When the short-circuit member 30 is assembled to the housing 10, the connecting portion 31 is housed in the connecting recess 21, the partitioning connection portion 33 is housed in the inner end of the branch recess 22, and the connection function portion 34 extends through the connection port 12 and is housed in the terminal housing chamber 11. The opening area of ​​the operation port 15 on the front surface 10F of the housing 10 is open throughout the entire surface.

[0054] like Figure 2 As shown, the terminal part 40 is formed into a shape that is elongated in the front-to-back direction as a whole. A square cylindrical terminal main body 41 is formed at the front end of the terminal part 40, and an open cylindrical crimping portion 43 is formed at the rear end of the terminal part 40. An elastic contact portion (not shown) that can elastically contact the connection function portion 34 is accommodated in the terminal main body 41.Figure 3 As shown, a locking portion 42 for locking with the lance 13 is formed on the lower surface of the terminal body 41. The crimping portion 43 is fixedly connected to the connecting end 51E of the main line 51 or the base end 52E of the branch line 52 so as to be conductive therewith.

[0055] The terminal parts 40 are stored in the terminal storage chamber 11 from the rear of the shell 10. In the two terminal storage chambers 11 at the top and the two terminal storage chambers 11 at the bottom of the three pairs of terminal storage chambers 11 arranged in two rows, the terminal parts 40 fixed to the connection end 51E of the main line 51 are inserted. The two terminal parts 40 inserted into the terminal storage chamber 11 at the top are terminal parts fixed to the connection end 51E constituting the differential pair line. The two terminal parts 40 inserted into the terminal storage chamber 11 at the bottom are also terminal parts fixed to the connection end 51E constituting the differential pair line. In the two terminal storage chambers 11 at the middle height, the two terminal parts 40 connected to the base end 52E of the branch line 52 are inserted. The two terminal parts 40 inserted into the terminal storage chamber 11 at the middle height are terminal parts fixed to the base end 52E of the branch line 52 constituting the differential pair line.

[0056] The terminal parts 40 housed in the terminal storage chamber 11 are kept in a non-detachable state by locking the locking portion 42 with the lance 13. When the terminal parts 40 are inserted into the terminal storage chamber 11, the three connection function parts 34 of each short-circuit member 30 individually enter the three terminal main body parts 41 arranged vertically and contact the elastic contact part. Thus, the three terminal parts 40 inserted into the three terminal storage chambers 11 arranged on the left and the short-circuit member 30 that connects these three terminal parts 40 constitute a branch circuit 45L (see Figure 1 、 4 The three terminal parts 40 inserted into the three terminal receiving chambers 11 arranged on the right and the short-circuit member 30 that conducts the three terminal parts 40 constitute a branch circuit 45R different from that on the left (see Figure 1 、 4 The left branch circuit 45L and the right branch circuit 45R formed inside the housing 10 constitute a differential pair.

[0057] When viewed from the front, there are no lances 13 between the left and right rows of terminal storage chambers 11. Therefore, compared to a case where lances 13 are placed between the left and right rows of terminal storage chambers 11, the distance between the left and right branch circuits 45L and 45R that make up the differential pair can be narrowed. There is only a single partition between the left and right terminal storage chambers 11, directly separating the two terminal storage chambers 11.

[0058] In this embodiment, the width of the connection function portion 34 of the short-circuit member 30 is 0.64 mm. The width of the terminal body 41 of the terminal fitting 40 is 1.5 mm, and the height of the terminal body 41 is 2.0 mm. The distance between the left-right center of the terminal body 41 of the terminal fitting 40 inserted into the left terminal receiving chamber 11 and the left-right center of the terminal body 41 of the terminal fitting 40 inserted into the right terminal receiving chamber 11 is set to 2.2 mm. This dimension setting ensures that the impedance of the differential pair within the housing 10 and the impedance of the main line 51 and branch line 52 outside the housing 10 are matched with high precision. As long as the distance between the left-right center of the terminal body 41 and the right-left center of the terminal body 41 is within the range of 2.1 mm to 2.3 mm, the impedance of the differential pair within the housing 10 and the impedance of the main line 51 and branch line 52 outside the housing 10 are well matched.

[0059] To remove the terminal component 40 from the terminal receiving chamber 11, a jig (not shown) is inserted through the operating opening 15 into the demolding space 14. The tip of the jig presses against the upper surface of the lance 13, causing the lance 13 to elastically displace downward, thereby disengaging the lance 13 from the retaining portion 42. This releases the lance 13 from the terminal component 40, allowing the terminal component 40 to be removed rearward by simply grasping the main line 51 or branch line 52 while the lance 13 is still elastically displaced. Because the operating opening 15 is fully open, inserting the jig into the operating opening 15 and elastically displacing the lance 13 with the jig are easy.

[0060] The connector A of this embodiment comprises a housing 10 made of synthetic resin, two metal short-circuit components 30, and three (or more) pairs of terminal components 40. The housing 10 comprises three (or more) pairs of terminal storage chambers 11 arranged in two left and right columns and arranged vertically. The two short-circuit components 30 are housed in the multiple (or three) terminal storage chambers 11 arranged in one column (left side) and the multiple (or three) terminal storage chambers 11 arranged in the other column (right side), respectively, forming a differential pair. The terminal components 40 are individually fixed to the trunk line 51 and the branch line 52 that constitute the differential pair.

[0061] The terminal parts 40 are connected to the short-circuit components 30 by being inserted into the terminal storage chambers 11. The terminal parts 40 stored in the terminal storage chamber 11 on the left and the terminal parts 40 stored in the terminal storage chamber 11 on the right constitute a differential pair. According to the configuration disclosed herein, a branch circuit 45L consisting of the short-circuit components 30 and terminal parts 40 stored in a plurality of terminal storage chambers 11 arranged in a row on one side, and a branch circuit 45R consisting of the short-circuit components 30 and terminal parts 40 stored in a plurality of terminal storage chambers 11 arranged in a row on the other side constitute a differential pair.

[0062] The housing 10 is provided with a plurality of lances 13 for individually preventing the terminal parts 40 inserted into the plurality of terminal receiving chambers 11 from coming out. Figure 6 When lances 13 are positioned laterally of the terminal receiving chambers 11, as in the illustrated housing 60, the terminal receiving chambers 11 and lances 13 are adjacent in a horizontal direction perpendicular to the arrangement of the terminal receiving chambers 11 in the left and right rows. With this arrangement, the placement of lances 13 between the terminal receiving chambers 11 in one row and the terminal receiving chambers 11 in the other row inevitably increases the spacing between the left and right differential pairs. Consequently, even if impedance matching is attempted by narrowing the spacing between the differential pairs, the matching is limited.

[0063] In contrast, in connector A of this embodiment, all of the multiple lances 13 are located only in an area separate from the area sandwiched between the multiple (three) terminal accommodating chambers 11 arranged in one row (left side) and the multiple (three) terminal accommodating chambers 11 arranged in the other row (right side). Because no lances 13 are located between the multiple terminal accommodating chambers 11 arranged in one row and the multiple terminal accommodating chambers 11 arranged in the other row, the spacing between the differential pairs in housing 10 can be kept sufficiently close. This increases the design freedom in setting the spacing between the differential pairs in housing 10, enabling highly accurate matching of the impedance within housing 10 with the impedance of the main line 51 and branch line 52 outside of housing 10.

[0064] In each row of terminal receiving chambers 11, multiple terminal receiving chambers 11 and multiple lances 13 are alternately arranged. This configuration allows the lances 13 (and the spaces for forming them) to fall within the row of terminal receiving chambers 11 in the width direction. Consequently, the housing 10 can be miniaturized in the direction (width direction) in which the short-circuit members 30 are arranged. The short-circuit members 30 are arranged in a left-right direction that is orthogonal to the direction in which the terminal receiving chambers 11 are arranged in each row.

[0065] In the front surface 10F of the housing 10, the connection port 12 connected to the terminal storage chamber 11 and the operation port 15 for disengaging the lance 13 from the terminal part 40 are opened in an alternating manner in the vertical direction. The short-circuit member 30 has a plurality of connection portions 32 and a connecting portion 31. The plurality of connection portions 32 are inserted into the terminal storage chamber 11 from the connection port 12 and are individually connected to the terminal part 40. The connecting portion 31 connects the plurality of connection portions 32 to each other. The connecting portion 31 is arranged at a position different from the operation port 15 when the housing 10 is viewed from the front, that is, at a position offset to the left or right relative to the operation port 15. According to this structure, even if the connection port 12 of the terminal storage chamber 11 and the operation port 15 for operating the lance 13 are arranged in a row, as long as the connecting portion 31 does not interfere with the operation of inserting a jig into the operation port 15 to displace the lance 13, it is sufficient.

[0066] The short-circuit member 30 is formed with a reinforcement portion 35 for reinforcing the connection function portion 34 of the connection portion 32. The reinforcement portion 35 is formed by extending the connection portion 32 forward and protruding from the coupling portion 31 in a rib-like shape. With this configuration, the reinforcement portion 35 can prevent deformation of the connection portion 32.

[0067] The connecting portions 31 of the two short-circuit members 30 are arranged so as to sandwich the terminal accommodating chambers 11 from the left and right when viewed from the front. Because no connecting portion 31 is positioned between the terminal accommodating chambers 11 in one row and the terminal accommodating chambers 11 in the other row, the spacing between the branch circuits 45L and 45R forming the differential pair within the housing 10 can be kept sufficiently close. This increases the design freedom in setting the spacing between the differential pairs within the housing 10, allowing for highly accurate matching of the impedance within the housing 10 with the impedance of the main line 51 and branch line 52 outside the housing 10.

[0068] The distance between the terminal parts 40 inserted into the terminal storage chambers 11 arranged in one row and the terminal parts 40 inserted into the terminal storage chambers 11 arranged in the other row is 2.1mm to 2.3mm. With this structure, the impedance inside the housing 10 can be matched with the impedance of the main line 51 and branch line 52 outside the housing 10 with high precision.

[0069] [Example 2]

[0070] Reference Figure 8 A second embodiment of the connector B disclosed herein will be described. The connector of this second embodiment has a short-circuit member 70 configured differently from that of the first embodiment. The remainder of the configuration is identical to that of the first embodiment, so identical components are denoted by the same reference numerals, and descriptions of the structure, function, and effects will be omitted.

[0071] The short-circuit member 70 is a single component made of a conductive material such as metal. The short-circuit member 70 has a connecting portion 71 and three connecting portions 72. The short-circuit member 70 of this embodiment 2 does not have the reinforcing portion 35 formed in the short-circuit member 30 of embodiment 1. The connecting portion 71 is formed in a flat plate shape with the plate thickness direction facing the left and right direction. The shape of the connecting portion 71 when the shell 10 is viewed from the side forms a longitudinally long rectangle. The upper and lower dimensions (height dimension) of the connecting portion 71 are the same dimensions as the upper and lower dimensions of the connecting recess 21 of the shell 10. The left and right dimensions (thickness dimension) of the connecting portion 71 are the same dimensions as the left and right dimensions (width dimension) of the connecting recess 21.

[0072] The three connecting portions 72 are connected to the rear end edge of the connecting portion 71 at three locations: the uppermost end, the lowermost end, and the center portion in the vertical direction. The three connecting portions 72 arranged in a vertically parallel manner are connected to each other via the connecting portion 71 so as to be conductive. The connecting portion 72 includes a partitioning connecting portion 73 protruding from the rear end edge of the connecting portion 71, and a connecting function portion 74 extending rearward in a cantilevered manner from the protruding end of the partitioning connecting portion 73. The partitioning connecting portion 73 of the short-circuit component 70 assembled in the storage recess 20 on the left side protrudes obliquely to the right front from the rear end edge of the connecting portion 71. The partitioning connecting portion 73 of the short-circuit component 70 assembled in the storage recess 20 on the right side protrudes obliquely to the left front from the rear end edge of the connecting portion 71.

[0073] The vertical dimension of the partitioning connection part 73 is the same as the vertical dimension of the branch recess 22. The horizontal projection dimension of the partitioning connection part 73 is the same as the horizontal length dimension of the branch recess 22. The vertical dimension of the connection function part 74 is the same as the vertical dimension of the connection port 12 (at Figure 8 The upper and lower dimensions of the connection function portion 74 are the same as the left and right dimensions of the connection port 12 (not shown).
