[0017] [Details of Embodiments of the Invention] <Embodiment 1> Reference will be made to Figures 1 to 7 The connector 100 of Embodiment 1 embodying the present application will be described. In this Embodiment 1, in the drawings, "front side" "rear side" "upper side" "lower side" "right side" and "left side" are indicated by "F" "B" "U" "D" "R" and "L", respectively. In this Embodiment 1, the left-right direction corresponds to the width direction. The front-rear direction corresponds to the direction in which the first opposing portion 12 and the counterpart dielectric body 62 are aligned.

[0018] As shown in Figure 4 , the connector 100 of Embodiment 1 is fitted to the circuit board P in a state of being placed on the mounting surface M of the circuit board P, and is mated with the counterpart connector 60 fitted to the terminal portion of the wire harness (not shown). As shown in Figure 1 , the connector 100 is constructed by assembling a plurality of dielectric bodies 10, a plurality of inner conductors 20 and an outer conductor 30.

[0019] [Structure of Dielectric Body] The dielectric body 10 has a first dielectric body 11 and a second dielectric body 21. The first dielectric body 11 and the second dielectric body 21 are made of synthetic resin. The first dielectric body 11 and the second dielectric body 21 are L-shaped when viewed from the side. The first dielectric body 11 is a single-piece member having a first opposing portion 12 as an opposing portion extending in the front-rear direction and a first extension portion 13. The first opposing portion 12 has a function as an opposing portion to be opposed to the counterpart dielectric body 62 of the counterpart connector 60 (see Figure 4 ). The first extension portion 13 is suspended downward at a right angle from the rear end portion of the first opposing portion 12. In other words, the first opposing portion 12 extends forward from the upper end portion of the first extension portion 13. A slit-like press-in opening portion 14 parallel to the length direction (the up-down direction) of the first extension portion 13 is formed in the rear surface 11R of the first dielectric body 11.

[0020] The second dielectric body 21 has the same basic shape as the first dielectric body 11. The second dielectric body 21 is a single-piece member having a second opposing portion 23 as an opposing portion extending in the front-rear direction and a second extension portion 24 extending downward from the rear end portion of the second opposing portion 23. The second opposing portion 23 has a function as an opposing portion to be opposed to the counterpart dielectric body 62 of the counterpart connector 60 (see Figure 4The second extension 24 is an extension that extends from the second opposing portion 23 in a right-angle direction. The length of the second opposing portion 23 of the second dielectric body 21 is shorter than the length of the first opposing portion 12 of the first dielectric body 11. The length of the second extension 24 of the second dielectric body 21 is shorter than the length of the first extension 13 of the first dielectric body 11. A slit-shaped press-in opening 25 parallel to the length direction (vertical direction) of the second extension 24 is formed on the rear surface 21R of the second dielectric body 21.

[0021] [Structure of the inner conductor] The inner conductor 20 has a first inner conductor 15 and a second inner conductor 22. Both the first inner conductor 15 and the second inner conductor 22 are made of conductive metal. Viewed from the side, the first inner conductor 15 and the second inner conductor 22 are L-shaped. The first inner conductor 15 is a single component having a first opposing side connection portion 16 and a first substrate side connection portion 17. The first opposing side connection portion 16 extends in the front-rear direction and connects to the opposing side inner conductor 63. The first substrate side connection portion 17 extends downward from the rear end of the first opposing side connection portion 16 and connects to the circuit board P (see reference). Figure 4 The first inner conductor 15 is assembled by pressing it into the first dielectric body 11 through the pressing opening 14. The first opposing side connection portion 16 of the first inner conductor 15 is housed in the first opposing portion 12. The first substrate side connection portion 17 of the first inner conductor 15 is housed in the first extension portion 13.

[0022] The basic shape of the second inner conductor 22 is the same as that of the first inner conductor 15. The second inner conductor 22 is a single component having a second opposing side connection portion 26 and a second substrate side connection portion 27. The second opposing side connection portion 26 extends in the front-rear direction and connects to the opposing side inner conductor 63. The second substrate side connection portion 27 extends downward from the rear end of the second opposing side connection portion 26 and connects to the circuit board P (see reference). Figure 4 The length of the second opposing side connection portion 26 of the second inner conductor 22 is shorter than the first opposing side connection portion 16 of the first inner conductor 15. The length of the second substrate side connection portion 27 of the second inner conductor 22 is shorter than the first substrate side connection portion 17 of the first inner conductor 15. The second inner conductor 22 is assembled by pressing it into the second dielectric body 21 through the pressing opening 25. The second opposing side connection portion 26 of the second inner conductor 22 is housed in the second opposing portion 23. The second substrate side connection portion 27 of the second inner conductor 22 is housed in the second extension portion 24. In this way, the two inner conductors 20 are respectively housed in the two dielectric bodies 10.

[0023] [Structure of the upper side of the outer conductor] The outer conductor 30 is constructed by assembling an upper outer conductor 31 and a lower outer conductor 40. The upper outer conductor 31 covers and houses the entire dielectric body 10 and the entire inner conductor 20 from above. The upper outer conductor 31 has two cylindrical surrounding portions 32 and one square surrounding portion 33. The two cylindrical surrounding portions 32 are cylindrical with their axes pointing in the front-back direction, and the rear and lower surfaces of the square surrounding portion 33 are open. The two cylindrical surrounding portions 32 are arranged vertically. The internal space of the square surrounding portion 33 communicates with the rear ends of the internal spaces of the two cylindrical surrounding portions 32. A protruding grounding connection portion 34 is formed on the lower surface of the square surrounding portion 33, which is connected to the grounding circuit (not shown) of the circuit board P.

[0024] like Figure 2 As shown, a pair of receiving portions 36 are provided within the square enclosure 33. The receiving portions 36 are arranged to receive the top end of the partition 43 (described later) of the lower outer conductor 40. Each receiving portion 36 is arranged to protrude inwards from the left and right inner walls of the square enclosure 33 in the left-right direction. In the vertical direction, each receiving portion 36 is located between the two cylindrical enclosure portions 32. The left-right inner end faces of each receiving portion 36 are positioned opposite each other at a predetermined distance in the left-right direction. These end faces are lateral receiving surfaces 37, which are receiving surfaces, and lateral opposing surfaces 47 (described later) of the lower outer conductor 40 are opposite to the lateral receiving surfaces 37. The lower end faces of each receiving portion 36 are formed by expanding in the horizontal direction. These lower end faces are downward receiving surfaces 38, which are receiving surfaces, and upward opposing surfaces 48 (described later) of the lower outer conductor 40 are opposite to the downward receiving surfaces 38. The lateral receiving surfaces 37 and the downward receiving surfaces 38 are connected at right angles.

[0025] like Figure 4 As shown, the dielectric body 10, which houses the inner conductor 20, is assembled into the upper outer conductor 31 through a mounting port 35 opening on the rear surface of the square enclosure 33. The upper cylindrical enclosure 32 houses the area of ​​the first opposing portion 12, excluding the rear end. The lower cylindrical enclosure 32 houses the area of ​​the second opposing portion 23, excluding the rear end. The square enclosure 33 houses the first extension 13, the second extension 24, the rear end of the first opposing portion 12, and the rear end of the second opposing portion 23.

[0026] Within the upper outer conductor 31, the second dielectric body 21 is disposed obliquely downward and in front of the first dielectric body 11. Specifically, the first opposing portion 12 and the second opposing portion 23 each extend in a front-rear direction. The second opposing portion 23 is disposed below the first opposing portion 12 at a predetermined distance relative to the first opposing portion 12. The first extension portion 13 and the second extension portion 24 each extend in a vertical direction. The second extension portion 24 is disposed in front of the first extension portion 13 at a predetermined distance relative to the first extension portion 13.

[0027] The counterpart terminal unit 61 of the counterpart connector 60 is inserted into the front end of the cylindrical enclosure 32 from the front of the connector 100. The counterpart terminal unit 61 is assembled from the counterpart inner conductor 63 and the counterpart dielectric body 62. When the connector 100 and the counterpart connector 60 are engaged, the first inner conductor 15 and the second inner conductor 22 are connected to the counterpart inner conductor 63 within the cylindrical enclosure 32, and the first dielectric body 11 and the second dielectric body 21 are opposite to the counterpart dielectric body 62. The front surface 11F of the first dielectric body 11 and the front surface 21F of the second dielectric body 21 are opposite to and abut against the front surface 62F of the counterpart dielectric body 62.

[0028] [Structure of the lower side of the outer conductor] like Figure 3 As shown, the lower outer conductor 40 is a single component having a bottom wall portion 41, a rear wall portion 42, and a partition portion 43. The rear wall portion 42 rises upward from the rear end edge of the bottom wall portion 41. The partition portion 43 rises upward from a position in front of the rear wall portion 42 of the bottom wall portion 41. A support portion 46 is provided at the upper end of the center portion in the left-right direction of the partition portion 43, and the support portion 46 protrudes upward in a prismatic shape. Opposing surfaces are formed in the upper region of the partition portion 43. For example, the two sides in the left-right direction of the support portion 46 are formed as lateral opposing surfaces 47, which are opposing surfaces facing the sides. An upward opposing surface 48 is formed on the outer side in the left-right direction of the support portion 46, which is an upward opposing surface. The lateral opposing surface 47 and the upward opposing surface 48 are connected at right angles. The lateral opposing surface 47 and the upward opposing surface 48 are formed at the top end of the partition portion 43.

[0029] On each lateral opposing surface 47, a protrusion 47A is provided, extending vertically and protruding outwards in the left-right direction. Viewed from above, the pair of protrusions 47A form an arc shape that curves outwards in the left-right direction. On each upward opposing surface 48, a protrusion 48A is provided, extending from the support portion 46 outwards in the left-right direction (width direction) and protruding upwards. Figure 5 As shown, when viewed from the side from the left and right directions, each protrusion 48A has a trapezoidal shape. Specifically, each protrusion 48A has: a top surface 48B, located above the upwardly opposing surface 48 and parallel to the upwardly opposing surface 48; and a pair of inclined surfaces 48C, which move forward and backward from the front and rear ends of the top surface 48B and are inclined downward. The pair of protrusions 47A and the pair of protrusions 48A are each arranged to clamp the support portion 46 from the left and right directions (width direction) (see reference). Figure 3 ).

[0030] like Figure 3As shown, between the partition portion 43 and the rear wall portion 42, the first penetration hole 44 is formed so as to penetrate in the up-down direction with respect to the bottom wall portion 41. In front of the partition portion 43, the second penetration hole 45 is formed so as to penetrate in the up-down direction with respect to the bottom wall portion 41. The partition portion 43 separates the first penetration hole 44 and the second penetration hole 45. The height of the partition portion 43 is lower than that of the rear wall portion 42 (see Figure 4 ).

[0031] [Assembly of the lower outer conductor with respect to the upper outer conductor] The assembly of the lower outer conductor 40 with respect to the upper outer conductor 31 is performed after the dielectric body 10, to which the inner conductor 20 is fitted, is received in the upper outer conductor 31. The lower outer conductor 40 is pressed into the upper outer conductor 31 from below so as to be fitted therewith. Specifically, the posture of the lower outer conductor 40 is such that the bottom wall portion 41 is disposed on the lower side, and the partition portion 43 is located in front of the rear wall portion 42. Also, the rear wall portion 42 is made to enter the fitting opening 35 from below. In conjunction therewith, the partition portion 43 is made to enter between the first extension portion 13 and the second extension portion 24 from below. Thereby, the partition portion 43 separates the first extension portion 13 and the second extension portion 24, which are adjacent in the front-rear direction (see Figure 4 ). The direction in which the partition portion 43 enters between the first extension portion 13 and the second extension portion 24 at this time is upward. This upward direction is the fitting direction Fd in which the lower outer conductor 40 is fitted with the upper outer conductor 31 (see Figure 4 ).

[0032] At this time, the plurality of press-in protrusions 49 (see Figure 3 ) provided to the lower outer conductor 40, which extend in the up-down direction in a rib shape, are flattened by the inner wall of the square-shaped surrounding portion 33, whereby the press-in of the lower outer conductor 40 with respect to the upper outer conductor 31 is performed. If the press-in of the lower outer conductor 40 into the upper outer conductor 31 is further performed, the support portion 46 enters between the pair of receiving portions 36 (see Figure 6 ). At this time, each of the protrusions 47A is flattened by each of the lateral receiving surfaces 37, whereby the support portion 46 is pressed into between the pair of receiving portions 36 from below (see Figure 6 ).

[0033] Also, if the press-in of the lower outer conductor 40 into the upper outer conductor 31 is further advanced, each of the protrusions 48A is flattened by the downward receiving surface 38 after coming into contact with the downward receiving surface 38 (see Figure 7 ). The downward receiving surface 38 and the upward opposing surface 48 extend in a direction orthogonal (crossing) to the fitting direction Fd (see Figure 7 ). In this way, the protrusions 47A, 48A come into contact with the lateral receiving surface 37 and the downward receiving surface 38, and the lateral receiving surface 37 and the downward receiving surface 38 are made to communicate with the lateral opposing surface 47 and the upward opposing surface 48 (see Figure 6 、 7). Then, when the upper end surface of the rear wall portion 42 contacts the upper end surface of the fitting opening 35 from below, the assembly of the lower outer conductor 40 to the upper outer conductor 31 is completed (see FIG. 6). Figure 4 ). The lower outer conductor 40 is assembled from below to the lower side covering dielectric body 10 and the inner conductor 20 (see FIG. 6). Figure 4 ). In this way, the assembly of the connector 100 is completed at the same time as the assembly of the outer conductor 30 is completed.

[0034] In the state where the connector 100 is assembled, the opening of the lower surface of the square surrounding portion 33 is closed by the bottom wall portion 41, and the opening of the rear surface of the square surrounding portion 33 is closed by the rear wall portion 42. As shown in FIG. 6, the support portion 46 is disposed so as to abut the lower end of the first opposing portion 12 from below and support the first opposing portion 12 from below. The lateral opposing surface 47 and the upward opposing surface 48 oppose the lateral receiving surface 37 and the downward receiving surface 38 formed in the receiving portion 36 (see FIG. 6). Figure 4 Figure 6 、 7 ).

[0035] The lower end portion of the first extension portion 13 is exposed to the lower side of the outer conductor 30 in the first through-hole 44. The lower end portion of the second extension portion 24 is exposed to the lower side of the outer conductor 30 at the second through-hole 45. The lower end portions of the first substrate side connecting portion 17 of the first inner conductor 15 and the second substrate side connecting portion 27 of the second inner conductor 22 protrude downward from the lower surface of the bottom wall portion 41 and are connected to the circuit board P. The partition portion 43 is disposed so as to partition the first extension portion 13 of the first dielectric body 11 and the second extension portion 24 of the second dielectric body 21 in the front-rear direction.

[0036] In the state where the connector 100 of the present embodiment 1 is mounted to the circuit board P, the ground connecting portion 34 of the outer conductor 30 is connected to the ground circuit (not shown) of the circuit board P. The first extension portion 13 of the first dielectric body 11 and the second extension portion 24 of the second dielectric body 21 extend in the up-down direction, and the lower surfaces oppose the mounting surface M of the circuit board P.

[0037] When the partner side connector 60 is fitted to the connector 100, the partner side outer conductor (not shown) is fitted so as to be conductive with the outer peripheral surface of the cylindrical surrounding portion 32, and the partner side dielectric body 62 is fitted into the cylindrical surrounding portion 32. In the upper cylindrical surrounding portion 32, the partner side inner conductor 63 and the first partner side connecting portion 16 are connected so as to be conductive. Along with this, the partner side dielectric body 62 and the first opposing portion 12 oppose in the front-rear direction. In the lower cylindrical surrounding portion 32, the partner side inner conductor 63 and the second partner side connecting portion 26 are connected so as to be conductive. Along with this, the partner side dielectric body 62 and the second opposing portion 23 oppose in the front-rear direction.

[0038] Next, the effects of the present structure will be illustrated.​ The connector 100 includes a plurality of dielectric bodies 10, a plurality of inner conductors 20 housed in the plurality of dielectric bodies 10, an upper outer conductor 31 covering the plurality of dielectric bodies 10 from above, and a lower outer conductor 40 covering the plurality of dielectric bodies 10 from below. The dielectric body 10 includes a first dielectric body 11 and a second dielectric body 21. The first dielectric body 11 includes a first extension 13 extending in the up-down direction with a lower surface facing the circuit board P. The second dielectric body 21 includes a second extension 24 extending in the up-down direction with a lower surface facing the circuit board P. The lower outer conductor 40 includes a partition 43 partitioning between the first extension 13 and the second extension 24 of adjacent dielectric bodies. The partition 43 includes a lateral facing surface 47 and an upward facing surface 48 at an upper end region. The upper outer conductor 31 includes a lateral receiving surface 37 and a downward receiving surface 38 facing the lateral facing surface 47 and the upward facing surface 48. The lateral facing surface 47 and the upward facing surface 48 include protrusions 47A and 48A in contact with the lateral receiving surface 37 and the downward receiving surface 38 to make the lateral receiving surface 37 and the downward receiving surface 38 conductive with the lateral facing surface 47 and the upward facing surface 48. According to this structure, the lateral receiving surface 37 and the downward receiving surface 38 are made conductive with the lateral facing surface 47 and the upward facing surface 48 by filling the space therebetween with the protrusions 47A and 48A, so that crosstalk between the first extension 13 and the second extension 24 of adjacent dielectric bodies can be easily suppressed.

[0039] The protrusions 47A and 48A are flattened by the lateral receiving surface 37 and the downward receiving surface 38. According to this structure, the conductive area of the lateral receiving surface 37 and the downward receiving surface 38 and the lateral facing surface 47 and the upward facing surface 48 can be enlarged, and the conductive reliability of the receiving portion 36 and the partition 43 can be improved.

[0040] The first dielectric body 11 includes a first facing portion 12 extending forward from an upper end of the first extension 13 with a front surface 11F facing an opposite dielectric body 62. The partition 43 of the lower outer conductor 40 includes a support portion 46 supporting the first facing portion 12 from below. The pair of protrusions 47A and the pair of protrusions 48A are arranged to sandwich the support portion 46 in the left-right direction (width direction). According to this structure, the protrusions 47A and 48A do not interfere with the first facing portion 12, and the lateral receiving surface 37 and the lateral facing surface 47 and the downward receiving surface 38 and the upward facing surface 48 are filled with the protrusions 47A and 48A.

[0041] The lower outer conductor 40 is fitted from below to the upper outer conductor 31. The downward receiving surface 38 and the upward opposing surface 48 extend in a direction orthogonal to the fitting direction Fd. A pair of protrusions 48A extend outward in the left-right direction (width direction) from the support portion 46. According to this structure, since the protrusions 48A are crushed by the downward receiving surface 38 and the upward opposing surface 48 in the final stage of fitting of the upper outer conductor 31 and the lower outer conductor 40, it is easy to suppress the fitting resistance of the upper outer conductor 31 and the lower outer conductor 40 midway through fitting.
