Specifically, as shown in FIG. 9, the fixing portions 61 of the large dielectric 60 are press-fitted from behind into the two upper housing chambers 36 of the outer conductor 30. At this time, the upper plate portion 83 of the shielding member 80 is press-fitted into the slit 39 of the partition wall 38 of the outer conductor 30. The pair of first protrusions 85 of the shielding member 80 bite into the upper wall of the slit 39. The second protrusion 86 bites into the lower wall of the slit 39. The guide portions 62 of the two large dielectrics 60 are housed in the two left and right housing spaces 34, respectively. The base portion 81, upper plate portion 83, and lower plate portion 84 of the shielding member 80 are arranged between the small dielectrics 160 and the large dielectrics 60 adjacent to each other in the front-rear direction. The lower end of the lower plate portion 84 protrudes downward further than the lower ends of the small dielectrics 160 and the large dielectrics 60 .

[0060] As shown in Figures 7 to 9, the shield terminal 10 is mounted on the circuit board 100. The lower end of the box-shaped main body 31 is attached to the circuit board 100. The large inner conductor 70 and the small inner conductor 170 are inserted into the mounting holes 101 and soldered to the signal electrical circuit (not shown) of the circuit board 100. The lower end of the lower plate 84 of the shielding member 80 comes into contact with the ground circuit 104.

[0061] <Effects of Example 1> The connector 1 of the first embodiment includes multiple pairs of large inner conductors 70 and small inner conductors 170 for differential communication, multiple large dielectrics 60 and small dielectrics 160 to which each pair of large inner conductors 70 and small inner conductors 170 is respectively assembled, and an outer conductor 30 that houses the multiple large dielectrics 60 and small dielectrics 160. The outer conductor 30 has multiple upper accommodating chambers 36 that are partially partitioned by partition walls 38 and that house a portion of each pair of large inner conductors 70, and multiple lower accommodating chambers 37 that are partially partitioned by partition walls 38 and that house a portion of each pair of small inner conductors 170. The large inner conductor 70 has a first connecting portion 71 that is housed in the upper accommodating chamber 36 and connected to a mating inner conductor (not shown), and a second connecting portion 72 that is exposed outside the upper accommodating chamber 36 and connected to a circuit board 100. The small inner conductor 170 has a first connection portion 171 that is accommodated in the lower accommodating chamber 37 and connected to a mating inner conductor (not shown), and a second connection portion 172 that is exposed to the outside of the lower accommodating chamber 37 and connected to the circuit board 100. A conductive shielding member 80 is provided between the second connection portion 72 of one pair of large inner conductors 70 assembled to the large dielectric 60 and the second connection portion 172 of the other pair of small inner conductors 170 assembled to the small dielectric 160 adjacent to this large dielectric 60. The shielding member 80 is in contact with the partition wall 38.

[0062] In this connector, the partition wall 38 of the outer conductor 30 is provided between the first connecting portions 71 of adjacent pairs of large inner conductors 70 and the first connecting portions 171 of adjacent pairs of small inner conductors 170, thereby suppressing the adverse effects of electromagnetic noise between the first connecting portions 71 and 171. Furthermore, because the shielding member 80 is in contact with the partition wall 38, no gap is created between the shielding member 80 and the partition wall 38 between adjacent pairs of large inner conductors 70 and the small inner conductors 170. This makes it possible to suppress the adverse effects of electromagnetic noise between adjacent pairs of large inner conductors 70 and the small inner conductors 170 compared to a configuration in which a gap exists. For example, the connector 1 can suppress the occurrence of electromagnetic interference, such as crosstalk, between adjacent pairs of large inner conductors 70 and the small inner conductors 170. In other words, the connector 1 can improve crosstalk performance.

[0063] In the connector 1 of the first embodiment, the outer conductor 30 has a slit 39 formed in the partition wall 38. The upper plate portion 83 of the shielding member 80 is press-fitted into the slit 39. In this connector 1, the shielding member 80 and the partition wall 38 can be maintained in a state of reliable contact.

[0064] In the connector 1 of the first embodiment, the shielding member 80 has an upper plate portion 83 (plate portion) that is inserted into the slit 39, and a first protrusion 85 (protrusion) and a second protrusion 86 (protrusion) that protrude from the upper plate portion 83. The first protrusion 85 and the second protrusion 86 contact the inner surface of the slit 39. In this connector 1, the shielding member 80 is prevented from coming off the slit 39 of the partition wall 38.

[0065] In the connector 1 of the first embodiment, the shielding member 80 has a first protrusion 85 protruding from one plate surface (upper surface) of the upper plate portion 83 (plate portion) and a second protrusion 86 protruding from the other plate surface (lower surface) of the upper plate portion 83. The first protrusions 85 and the second protrusions 86 are alternately arranged in a direction parallel to the plate surface of the plate portion. The first protrusions 85 and the second protrusions 86 contact the inner surface of the slit 39. In this connector 1, the upper plate portion 83 elastically deforms as the first protrusions 85 and the second protrusions 86 contact the inner surface of the slit 39, and the elastic restoring force of the upper plate portion 83 allows all of the protrusions to contact the inner surface of the slit 39, ensuring sufficient contact pressure.

[0066] In the connector 1 of the first embodiment, the shielding member 80 is disposed between the entire portion of the second connecting portion 72 of one pair of large inner conductors 70 that is accommodated in the large dielectric 60 (the entire inclined portion 75 and the upper end of the vertical portion 76) and the entire portion of the second connecting portion 172 of the other pair of small inner conductors 170 that is accommodated in the small dielectric 160 (the entire inclined portion 175 and the upper end of the vertical portion 176). In this connector 1, the adverse effects of electromagnetic noise can be suppressed between the portions of the pair of second connecting portions 72 and the pair of second connecting portions 172 that are accommodated in the large dielectric 60 and the portions that are accommodated in the small dielectric 160.

[0067] In the connector 1 of the first embodiment, the shielding member 80 is in contact with the ground circuit 104 of the circuit board 100. In this connector 1, the current flowing through the shielding member 80 can be released to the circuit board 100.

[0068] [Example 2] A second embodiment of the present disclosure will be described below with reference to Figures 10 and 11. The connector of the second embodiment is different from that of the first embodiment in the shape of the shielding member, but is otherwise the same. Note that the same components as those of the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted.

[0069] The connector of Example 2 includes a shielding member 280 shown in FIG. 10. A pair of third protrusions 285 are formed on the upper plate portion 83 of the shielding member 280. The third protrusions 285 are an example of the "protrusions" of the present disclosure. The pair of third protrusions 285 protrude outward in the left-right direction from the center in the front-rear direction of the left and right edges of the upper plate portion 83. The third protrusions 285 are semicircular plate pieces when viewed from the top-bottom direction. The top and bottom surfaces of the third protrusions 285 are flush with the top and bottom surfaces of the upper plate portion 83.

[0070] 11, a pair of third protrusions 285 of the shielding member 280 are respectively embedded in the inner surfaces of the slit 39 (the left and right wall portions constituting the slit 39). No gap is generated between the outer conductor 30 and the shielding member 280 in the directions in which the large dielectric 60 and the small dielectric 160 adjacent to this large dielectric 60 face each other (front-rear and up-down directions).

[0071] Even with this configuration, since the shielding member 280 is in contact with the partition wall 38, no gaps are created between the shielding member 280 and the partition wall 38 between adjacent pairs of large inner conductors 70 and pairs of small inner conductors 170, and the adverse effects of electromagnetic noise between adjacent pairs of large inner conductors 70 and pairs of small inner conductors 170 can be suppressed compared to a configuration in which gaps exist.

The present invention includes the meaning equivalent to the claims and all modifications within the scope of the claims, including the following embodiments.

[0073] In the above-mentioned Examples 1 and 2, the upper plate portion 83 of the shielding member 80 was press-fitted into the slit 39 of the partition wall 38 of the outer conductor 30, but it may also be configured to contact the outer surface of the partition wall 38 without entering the slit 39.

[0074] In the above-mentioned Examples 1 and 2, the pair of side plate portions 82 of the shielding member contact the left and right inner walls 31A (more specifically, the recess 31B) that form the storage space 34 of the box-shaped main body portion 31, but they do not have to contact the box-shaped main body portion 31.

[0075] In the above-mentioned Examples 1 and 2, the lower end of the lower plate portion 84 of the shielding member is in contact with the ground circuit 104 of the circuit board 100, but the lower end of the lower plate portion 84 of the shielding member may be inserted into a through-hole provided in the circuit board 100 and electrically connected to the circuit board 100.

[0076] In the above-described first and second embodiments, the first connecting portion 71 and the second connecting portion 72 of the large inner conductor 70 may extend in directions that form a right angle with each other. Also, the first connecting portion 171 and the second connecting portion 172 of the small inner conductor 170 may extend in directions that form a right angle with each other.
