AI Technical Summary
Existing compression type connectors suffer from deteriorated transmission characteristics due to mismatched impedances between the terminal portions when the distance between the shell and the contact portion is too large.
The connector design includes a housing with terminals arranged in the pitch direction, where the shell has upper and lower plate parts that closely match the impedances of the terminal portions by positioning the second upper plate part near the contact portion and the second lower plate part near the connected portion, while maintaining electrical connectivity and shielding.
This design improves transmission characteristics by matching the impedances of the terminal portions, enhancing signal integrity and reducing electromagnetic interference.

When the connector 10 is assembled, the two through holes 452 of the shell 40, the two through holes 282 of the housing 20, and the two through holes 552 of the additional shell 50 are aligned in the vertical direction to form two through holes 18. Each of the through holes 18 penetrates the connector 10 in the vertical direction.
[0058] 1, the connector 10 of this embodiment is fixed to the second object 80 as described below. Referring to FIGS. 1 and 2 together with FIG. 4, first, the positioning portions 288 are inserted into the positioning holes 88, respectively, to position the connector 10 on the second object 80. Next, the connector 10 is pressed against the second object 80 and temporarily fixed by the positioning portions 288. Next, two screws 89 are passed through the through hole 552 and the through hole 86 of the second object 80, respectively, and screwed into nuts (not shown). As a result, the connector 10 is securely fixed to the second object 80.
[0059] 2 and 4, according to this embodiment, the cross section of each of the positioning portions 288 in the XY plane partially protrudes from the cross section of the positioning hole 88 in the XY plane. Also, each of the positioning portions 288 has a bifurcated structure that is elastically deformable in the XY plane. As a result of positioning by the positioning portions 288 and the positioning holes 88, the connector 10 is temporarily fixed to the second object 80. However, the present invention is not limited to this. For example, the cross section of each of the positioning portions 288 in the XY plane may be smaller than the cross section of the positioning hole 88 in the XY plane. The positioning portions 288 may be provided as necessary.
[0060] 8 and 10 together with FIG. 2, the flat lower plate 51 of the additional shell 50 contacts the ground pattern 85 of the second object 80 when the connector 10 is fixed to the second object 80, so that the shell 40 and the additional shell 50 are grounded to the ground pattern 85 and have the same ground potential. The terminal structure 16 (see FIG. 11) is covered above and below by the shell 40 and the additional shell 50, and is also covered from the front. As a result, the terminal structure 16 is electromagnetically shielded. The connector 10 of this embodiment can effectively suppress EMI (Electro Magnetic Interference) due to the above-mentioned structure. However, the present invention is not limited to this, and the structures of the shell 40 and the additional shell 50 can be modified as necessary.
[0061] 14 and 15, the terminals 30 of this embodiment have the same shape. However, the present invention is not limited to this. For example, the terminals 30 may have different shapes. Below, one of the terminals 30 will be described. The following description is applicable to each of the terminals 30.
[0062] The terminal 30 in this embodiment is a single metal plate having a bend. The terminal 30 has a held portion 32, a first portion 34, and a second portion 36. The terminal 30 in this embodiment has only the held portion 32, the first portion 34, and the second portion 36. In this embodiment, the held portion 32, the first portion 34, and the second portion 36 are each part of a single terminal 30. However, the present invention is not limited to this. For example, the terminal 30 may be formed by joining a plurality of metal plates. The terminal 30 may further have another portion in addition to the above-mentioned portions.
[0063] 14 and 15 together with FIG. 7, the held portion 32 in this embodiment extends straight along the front-rear direction and is held by the holding portion 22 of the housing 20. The held portion 32 is embedded in the holding portion 22. More specifically, the held portion 32 is surrounded by the thick holding portion 22 without any gaps in the vertical plane (YZ plane). The first portion 34 extends rearward from the held portion 32. The first portion 34 is embedded inside the housing 20 except for the upper surface and rear end. The second portion 36 extends forward from the held portion 32. Most of the second portion 36 is located inside the storage portion 14 and is partially embedded inside the housing 20.
[0064] The first portion 34 of the present embodiment has a connected portion 342 and an embedded portion 344. The connected portion 342 extends straight backward from the rear end of the held portion 32 along the upper surface of the base portion 23 of the housing 20. The connected portion 342 is embedded inside the base portion 23 except for the upper surface. The upper surface of the connected portion 342 is a plane parallel to the XY plane, is exposed upward from the base portion 23, and faces the receiving portion 12. The embedded portion 344 extends backward while curving from the rear end of the connected portion 342. The embedded portion 344 is embedded inside the base portion 23 except for the rear end. The rear end of the embedded portion 344 protrudes backward from the base portion 23. Referring to FIG. 8, the connected portion 342 is connected to the first object 70. In detail, the core wire 72 of the first object 70 is fixed and connected to the upper surface of the connected portion 342 by soldering.
[0065] 14 and 15 together with Fig. 7, the second section 36 of the present embodiment has an extension portion 362, a folded-back portion 364, a support portion 366, a contact portion 38, and a tip portion 368. The second section 36 is exposed from the housing 20 except for a portion of the upper surface of the extension portion 362. A middle portion of the second section 36 in the pitch direction is partially cut out.
[0066] The extension portion 362 extends forward from the held portion 32. More specifically, the extension portion 362 extends straight forward from the front end of the held portion 32 along the lower surface of the interposition portion 26 of the housing 20. The folded-back portion 364 is connected to the front end of the extension portion 362 and folded back rearward. The support portion 366 extends rearward from the folded-back portion 364. More specifically, the support portion 366 extends straight rearward from the rear end of the folded-back portion 364, then extends rearward and downward, and then extends rearward and upward. The contact portion 38 is provided on the support portion 366. The tip 368 is the rear end of the support portion 366.
[0067] 7 and 9, the support portion 366 formed as described above is elastically deformable with the tip 368 as a free end. The contact portion 38 is supported by the support portion 366 and can move in the vertical direction with the elastic deformation of the support portion 366. The contact portion 38 in this embodiment faces downward. More specifically, the contact portion 38 is located at the lower end of the support portion 366 and protrudes downward. When the connector 10 is away from the second object 80 (see FIGS. 8 and 10), the second portion 36 of the terminal 30 is accommodated in the accommodation portion 14 except for the portion around the contact portion 38, and the contact portion 38 protrudes downward through the pilot hole 512 of the additional shell 50.
[0068] 8 and 10, when the connector 10 is fixed to the second object 80, the contact portion 38 is pressed against the second object 80. More specifically, the contact portion 38 is pressed against the corresponding conductive pad 84 of the second object 80 while elastically deforming the support portion 366, and the connector 10 is electrically connected to the second object 80. According to this embodiment, the contact portion 38 is electrically connected to the conductive pad 84 simply by pressing it, without using a fixing means such as soldering. Therefore, the connector 10 can be removed from the second object 80 by simply removing the screw 89 (see FIG. 1).
[0069] The support portion 366 of this embodiment is a cantilever beam and is easily bent. In addition, according to the structure of the second portion 36 of this embodiment, the spring length of the second portion 36 including the support portion 366 can be increased, and the amount of movement of the contact portion 38 in the vertical direction can be increased. Even if the contact portion 38 moves a large amount, the tip 368 moves inside the storage portion 14 without hitting other portions or members.
[0070] However, the present invention is not limited to this embodiment. For example, the connector 10 may be connected to the second object 80 along the front-rear direction. More specifically, the second object 80 may extend along the YZ plane. The connector 10 may open forward. The contact portion 38 may be located at the front end of the support portion 366. The contact portion 38 may protrude forward through the opening of the connector 10 when the connector 10 is away from the second object 80.
[0071] Each of the terminals 30 in this embodiment has the structure described above. However, the present invention is not limited to this, and the structure of each of the terminals 30 can be modified as necessary. For example, the embedded portion 344, the extension portion 362, the folded portion 364, and the tip 368 may be provided as necessary. When the extension portion 362 and the folded portion 364 are not provided, each of the support portions 366 may extend forward and downward from the front end of the held portion 32.
[0072] 14 and 15, the terminal 30 of this embodiment includes four separated terminals 302, fourteen connecting terminals 304, and ten predetermined terminals 306.
[0073] No connecting plate 31 is provided behind each of the separate terminals 302. Each of the connecting terminals 304 is provided with a connecting portion 316 that is a part of the connecting plate 31. Each of the connecting portions 316 is connected to the rear end of the first portion 34 of the connecting terminal 304, and connects the connecting terminal 304 and the connecting plate 31 to each other in the front-rear direction. Each of the predetermined terminals 306 is provided with a mounting portion 314 that is a part of the connecting plate 31. Each of the mounting portions 314 is located rearward and away from the first portion 34 of the predetermined terminal 306. The first portion 34 of each of the predetermined terminals 306 is located at the same position in the pitch direction as the rear mounting portion 314.
[0074] In the present embodiment, each of the mounting portions 314 is located below the connected portions 342 of the predetermined terminals 306. However, the present invention is not limited to this. For example, each of the mounting portions 314 may be located at the same position as the connected portions 342 of the predetermined terminals 306 in the up-down direction.
[0075] 8 and 10, the forward ends of all of the cables 70 are received in the receptacles 12 and are respectively connected to the terminals 30 as described below.
[0076] 13, each of the discrete cables 702 is connected to a separate terminal 302. That is, the terminal 30 includes one or more separate terminals 302 that are each connected to a discrete cable 702. The core wire 72 of each of the discrete cables 702 is fixed and connected to the connected portion 342 of the separate terminal 302 by soldering. With this structure, a low-frequency signal can be transmitted to the separate terminal 302 via each of the discrete cables 702.
[0077] Each of the discrete cables 704 is connected to a connecting terminal 304. That is, the terminal 30 includes one or more connecting terminals 304 that are respectively connected to the discrete cables 704. Each core wire 72 of the discrete cables 704 is fixed and connected to a connected portion 342 of the connecting terminal 304 by soldering. With this structure, a power supply voltage can be supplied to four connecting terminals 304 via one or two discrete cables 704.
[0078] Each of the predetermined cables 706 is connected to a predetermined terminal 306. That is, the terminal 30 includes one or more predetermined terminals 306 each corresponding to a predetermined cable 706. The core wire 72 of each of the predetermined cables 706 is fixed and connected to the connected portion 342 of the corresponding predetermined terminal 306 by soldering. Each of the ground conductors 76 is mounted on the mounting portion 314 at the rear of the corresponding predetermined terminal 306, and fixed and connected by soldering.
[0079] According to this embodiment, two connecting terminals 304 connected to a common connecting plate 31 are located on both sides of two predetermined terminals 306 in the pitch direction. This structure allows high-frequency signals to be transmitted to the two predetermined terminals 306 via the two predetermined cables 706, and allows two connecting terminals 304 having ground potential to be arranged on both sides of the two predetermined terminals 306 in the pitch direction. As a result, the transmission characteristics of high-frequency signals can be improved. In addition, since the mounting portion 314 is located below the connected portion 342, the front end of the predetermined cable 706 can be extended straight along the front-rear direction.
[0080] The terminals 30 in this embodiment are arranged as described above, and connected to the first object 70 as described above. However, the present invention is not limited to this. For example, the two connecting terminals 304 may be located on both sides of one predetermined terminal 306 in the pitch direction. Each of the discrete cables 704 may be connected to a connecting portion 316 behind the connecting terminal 304.
[0081] The upper plate 41 (see FIG. 3) of the shell 40 of this embodiment will now be described in more detail.
[0082] 1 and 3, the connecting portion 44 and the second upper plate portion 43 are formed by bending a metal piece formed by partially cutting out the upper plate 41. As a result, the second upper plate portion 43 is connected to the first upper plate portion 42 via the connecting portion 44. In particular, the connecting portion 44 in this embodiment connects the entire front end of the first upper plate portion 42 and the entire rear end of the second upper plate portion 43 to each other. The connecting portion 44 is separated from the shell 40 except for the first upper plate portion 42 and the second upper plate portion 43. The second upper plate portion 43 is separated from the shell 40 except for the connecting portion 44 and the front plate 46. The edges on both sides in the pitch direction of the connecting portion 44 and the second upper plate portion 43 are not connected to any part of the shell 40.
[0083] 11 together with FIG. 7, the first upper plate portion 42 extends over two or more terminals 30 along the pitch direction and covers the first portions 34 of the terminals 30 from above in the vertical direction. In particular, the first upper plate portion 42 of the present embodiment covers all of the first portions 34 from above. The second upper plate portion 43 extends over two or more terminals 30 along the pitch direction and covers the second portions 36 of the terminals 30 from above. In particular, the second upper plate portion 43 of the present embodiment covers all of the second portions 36 from above. The second upper plate portion 43 is located below the first upper plate portion 42.
[0084] Referring to FIG. 8, the first upper plate portion 42 of the shell 40 having a ground potential covers the receiving portion 12 in which the first portion 34 of the terminal 30 is disposed from above. The first object 70 is connected to the connected portion 342 of the first portion 34 in the receiving portion 12. In general, the receiving portion 12 needs to be large enough to receive the first object 70. More specifically, the distance between the first upper plate portion 42 and the connected portion 342 needs to be some distance. In particular, when the first object 70 is a cable 70, the first upper plate portion 42 needs to be some distance away from the connected portion 342 to prevent a short circuit between the core wire 72 of the first object 70 and the shell 40. According to the conventional technology, the entire first upper plate 41 of the shell 40 is formed so as to be separated upward from the terminal 30.
[0085] Even if the first upper plate 41 having the ground potential is separated from the terminal 30, the held portion 32 of the terminal 30 is covered with an insulator, and the impedance can be made relatively low. Although the first portion 34 of the terminal 30 is partially exposed to the receiving portion 12, the ground conductor 76 of the cable 70 is located nearby, and the impedance can be made relatively low. On the other hand, the second portion 36 of the terminal 30 is mostly exposed to the receiving portion 14, and the impedance is likely to be high. According to the conventional technology, the impedance of the second portion 36 does not match the impedance of the held portion 32 and the first portion 34, and the transmission characteristics are likely to deteriorate.
[0086] On the other hand, according to the present embodiment, the second upper plate portion 43 of the shell 40 is located below the first upper plate portion 42, and covers from above the second portion 36 where the contact portion 38 of the terminal 30 is provided. That is, the second upper plate portion 43 is provided so as to be close to the second portion 36. With this structure, the impedances of the first portion 34, the second portion 36, and the held portion 32 are matched, thereby improving the transmission characteristics. As described above, according to the present embodiment, it is possible to provide a compression-type connector 10 capable of improving the transmission characteristics.
[0087] According to this embodiment, the connecting portion 44 and the second upper plate portion 43 are formed by cutting and bending a part of the shell 40. According to this forming method, the second upper plate portion 43 can be moved far away from the first upper plate portion 42 in the vertical direction and close to the second portion 36. Moreover, the second upper plate portion 43 in this embodiment has a flat plate shape without any irregularities and extends along the XY plane. However, the present invention is not limited to this. For example, when the position of the second portion 36 in the vertical direction or the position in the front-rear direction is not constant, the position of the second upper plate portion 43 in the vertical direction or the position in the front-rear direction may be adjusted according to the arrangement of the second portion 36. For example, the second upper plate portion 43 may be formed with two or more portions whose positions in the vertical direction are different from each other.
[0088] According to this embodiment, the first upper plate portion 42, the connecting portion 44, and the second upper plate portion 43 extending along the pitch direction are connected without any gaps in the front-rear direction. This structure makes it easy to improve the transmission characteristics. However, the present invention is not limited to this. For example, two or more connecting portions 44 and two or more second upper plate portions 43 may be formed at necessary locations according to the arrangement of the second section 36.
[0089] 1 and 3, according to the method of forming the connecting portion 44 and the second upper plate portion 43 of the present embodiment, the housing 20 is partially exposed to the outside. That is, the housing 20 of the present embodiment has one or more visible portions 29 exposed to the outside. Each of the visible portions 29 is adjacent to the connecting portion 44, is at least partially in the same position as the connecting portion 44 in the up-down direction, and is visible from outside the first connector 10.
[0090] According to this embodiment, the connecting portion 44 is located between the first upper plate portion 42 and the second upper plate portion 43 in the front-rear direction, and extends along the pitch direction. With this structure, the one or more visible portions 29 in this embodiment include two visible portions 29. The two visible portions 29 are located on both sides of the connecting portion 44 in the pitch direction.
[0091] 7 and 9, according to the present embodiment, the intervening portion 26 of the housing 20 partially covers the second portion 36 of each of the terminals 30. The intervening portion 26 is interposed between the second upper plate portion 43 and the second portion 36. By providing the intervening portion 26, the distance between the second upper plate portion 43 and the second portion 36 can be easily kept constant. That is, according to the present embodiment, it is easy to reduce the distance between the second upper plate portion 43 and the second portion 36 while preventing a short circuit between the second upper plate portion 43 and the second portion 36. However, the present invention is not limited thereto, and the intervening portion 26 may be provided as necessary.
[0092] The lower plate 51 of the additional shell 50 of this embodiment will now be described in more detail.
[0093] 4, the additional connecting portion 54 and the second lower plate portion 53 are formed by bending a metal piece formed by partially cutting out the first lower plate portion 52. As a result, the second lower plate portion 53 is connected to the first lower plate portion 52 via the additional connecting portion 54. In particular, the additional connecting portion 54 in this embodiment connects the entire front end of the second lower plate portion 53 to the first lower plate portion 52. Meanwhile, the additional connecting portion 54 and the second lower plate portion 53 are separated from other portions of the additional shell 50.
[0094] 4 together with FIG. 7, the first lower plate portion 52 extends along the pitch direction and covers the mounting portions 314 behind the predetermined terminals 306 from below. In particular, the first lower plate portion 52 of the present embodiment covers all of the mounting portions 314 from below. The second lower plate portion 53 extends along the pitch direction and covers the connected portions 342 of the predetermined terminals 306 from below. In particular, the second lower plate portion 53 of the present embodiment covers the connected portions 342 of all of the predetermined terminals 306 from below. The second lower plate portion 53 is located above the first lower plate portion 52.
[0095] 8, the impedance of the connected portion 342 of the first portion 34 of the predetermined terminal 306 tends to be relatively high compared to the mounting portion 314 on which the ground conductor 76 of the first object 70 is mounted. On the other hand, according to the present embodiment, the second lower plate portion 53 of the additional shell 50 is located above the first lower plate portion 52, and covers the connected portion 342 of the predetermined terminal 306 from below. That is, the second lower plate portion 53 is provided so as to be close to the connected portion 342. With this structure, the impedances of the first portion 34, the second portion 36, and the held portion 32 are further matched, thereby further improving the transmission characteristics.
[0096] According to this embodiment, the additional connecting portion 54 and the second lower plate portion 53 are provided only under the predetermined terminal 306 that transmits high-frequency signals. With this structure, most of the lower plate 51 of the additional shell 50 can be formed in a plane parallel to the XY plane. As a result, the connector 10 can be stably mounted on the second object 80 while improving the transmission characteristics. However, the present invention is not limited to this. For example, the additional connecting portion 54 and the second lower plate portion 53 may be provided under all the terminals 30. On the other hand, the additional connecting portion 54 and the second lower plate portion 53 may be provided as necessary.
[0097] According to this embodiment, the additional connecting portion 54 and the second lower plate portion 53 are formed by cutting and bending a part of the additional shell 50. In addition, the first lower plate portion 52, the additional connecting portion 54, and the second lower plate portion 53 extending along the pitch direction are connected without any gaps in the front-rear direction. This structure makes it easy to improve the transmission characteristics. However, the present invention is not limited to this. The structures of the first lower plate portion 52, the additional connecting portion 54, and the second lower plate portion 53 can be modified as necessary. For example, the second lower plate portion 53 may be formed by partially drawing or embossing the first lower plate portion 52.
[0098] In addition to the various modifications already described, this embodiment can be modified in various ways. Three modifications of the shell 40 will be described below.
[0099] 16 with FIG. 3, connector 10A according to the first modification includes a shell 40A that is different from shell 40 of connector 10. Except for this difference, connector 10A is formed from the same materials as connector 10.
[0100] The shell 40A has an upper plate 41A that is different from the upper plate 41 of the shell 40. The upper plate 41A has a first upper plate portion 42A, a second upper plate portion 43A and a connecting portion 44A that are different from the first upper plate portion 42, the second upper plate portion 43 and the connecting portion 44 of the upper plate 41, respectively, and has the same two side portions 45 as the upper plate 41. Except for the above-mentioned differences, the upper plate 41A has the same structure as the upper plate 41.
[0101] 16 to 18, the first upper plate portion 42A extends over two or more terminals 30 in the pitch direction and covers the first portions 34 of the terminals 30 from above in the vertical direction. The second upper plate portion 43A extends over two or more terminals 30 in the pitch direction and covers the second portions 36 of the terminals 30 from above. The second upper plate portion 43A is located below the first upper plate portion 42A.
[0102] The second upper plate portion 43A and the connecting portion 44A are formed by cutting and bending the first upper plate portion 42A. The second upper plate portion 43A is connected to the first upper plate portion 42A via the connecting portion 44A. More specifically, the connecting portion 44A extends along the pitch direction. The connecting portion 44A is connected to the front end of the first upper plate portion 42A and is folded back toward the rear. The second upper plate portion 43A is connected to the rear end of the connecting portion 44A and extends toward the rear.
[0103] The housing 20 has one or more visible portions 29A. Each of the visible portions 29A is adjacent to the connecting portion 44A. Each of the visible portions 29A is at least partially at the same position as the connecting portion 44A in the up-down direction, and is visible from the outside of the first connector 10A. In particular, the one or more visible portions 29A include two visible portions 29A. The two visible portions 29A are located on both sides of the connecting portion 44A in the pitch direction.
[0104] The above-described structure matches the impedance of the first portion 34, the second portion 36, and the held portion 32, thereby improving the transmission characteristics. According to this modification, it is possible to provide a compression-type connector 10A that can improve the transmission characteristics.
[0105] 19 with FIG. 3, a connector 10B according to the second modification includes a shell 40B that is different from the shell 40 of the connector 10. Except for this difference, the connector 10B is formed from the same members as the connector 10.
[0106] Shell 40B has an upper plate 41B that is different from upper plate 41 of shell 40. Upper plate 41B has a first upper plate portion 42B, a second upper plate portion 43B and a connecting portion 44B that are different from the first upper plate portion 42, the second upper plate portion 43 and the connecting portion 44 of upper plate 41, respectively, and has the same two side portions 45 as upper plate 41. Except for the above-mentioned differences, upper plate 41B has the same structure as upper plate 41.
[0107] 19 to 21, the first upper plate portion 42B extends across two or more terminals 30 in the pitch direction and covers the first portions 34 of the terminals 30 from above in the vertical direction. The second upper plate portion 43B extends across two or more terminals 30 in the pitch direction and covers the second portions 36 of the terminals 30 from above. The second upper plate portion 43B is located below the first upper plate portion 42B.
[0108] The second upper plate portion 43B and the connecting portion 44B are formed by cutting and bending the first upper plate 41B. The second upper plate portion 43B is connected to the first upper plate portion 42B via the connecting portion 44B. More specifically, the connecting portion 44B extends along the front-rear direction. The connecting portion 44B is connected to the inner end in the pitch direction of one of the two side portions 45, and extends inward and downward in the pitch direction. The second upper plate portion 43B is connected to the lower end of the connecting portion 44B and extends along the pitch direction.
[0109] The housing 20 has one or more visible portions 29B. One of the visible portions 29B is adjacent to the connecting portion 44B. Each of the visible portions 29B is at least partially at the same position as the connecting portion 44B in the up-down direction, and is visible from the outside of the first connector 10B. In particular, the one or more visible portions 29B include two visible portions 29B. The two visible portions 29B are located on both sides of the second upper plate portion 43B in the pitch direction.
[0110] The above-described structure matches the impedance of the first portion 34, the second portion 36, and the held portion 32, thereby improving the transmission characteristics. According to this modification, a compression-type connector 10B capable of improving the transmission characteristics can be provided.
[0111] 22 with FIG. 3, a connector 10C according to the third modification includes a shell 40C that is different from the shell 40 of the connector 10. Apart from this difference, the connector 10C is formed from the same members as the connector 10.
[0112] The shell 40C has an upper plate 41C that is different from the upper plate 41 of the shell 40. The upper plate 41C has a first upper plate portion 42C, two second upper plate portions 43C and two connecting portions 44C that are different from the first upper plate portion 42, the second upper plate portion 43 and the connecting portion 44 of the upper plate 41, respectively, and has the same two side portions 45 as the upper plate 41. Except for the above-mentioned differences, the upper plate 41C has the same structure as the upper plate 41.
[0113] 22 to 24, the first upper plate portion 42C extends over two or more terminals 30 in the pitch direction and covers the first portions 34 of the terminals 30 from above in the vertical direction. Each of the second upper plate portions 43C extends over two or more terminals 30 in the pitch direction and covers the second portions 36 of the terminals 30 from above. Each of the second upper plate portions 43C is located below the first upper plate portion 42C.
[0114] According to this modification, two sets each consisting of one second upper plate portion 43C and one connecting portion 44C are provided. Each set is formed by cutting and bending the first upper plate 41C. In each set, the second upper plate portion 43C is connected to the first upper plate portion 42C via the connecting portion 44C. In detail, each connecting portion 44C extends along the front-rear direction. Each connecting portion 44C is connected to the inner end in the pitch direction of one of the two side portions 45, and extends inward and downward in the pitch direction. Each second upper plate portion 43C is connected to the lower end of the connecting portion 44C and extends along the pitch direction. That is, the two second upper plate portions 43C extend along the pitch direction from the two side portions 45 so as to approach each other.
[0115] The housing 20 has one or more visible portions 29C. In particular, the one or more visible portions 29C include two visible portions 29C. The two visible portions 29C are adjacent to the connecting portions 44C, respectively. The two visible portions 29C are at least partially at the same position as the connecting portions 44C in the up-down direction, and are visible from the outside of the first connector 10C. The two visible portions 29C are each located outside the two second upper plate portions 43C in the pitch direction. The one or more visible portions 29C include, in addition to the two visible portions 29C described above, one visible portion 29C located between the two second upper plate portions 43C in the pitch direction.
[0116] The above-described structure matches the impedance of the first portion 34, the second portion 36, and the held portion 32, thereby improving the transmission characteristics. According to this modification, a compression-type connector 10C capable of improving the transmission characteristics can be provided.
[0117] 3, the second upper plate portion 43 of the connector 10 is grounded to the second object 80 (see FIG. 1) via the front plate 46 and the additional shell 50. On the other hand, the second upper plate portion 43A (see FIG. 18), the second upper plate portion 43B (see FIG. 19), and the second upper plate portion 43C (see FIG. 22) of the above-mentioned modified example are not connected to a portion grounded to the second object 80, and form stubs on the transmission path of the ground signal. Therefore, in consideration of the transmission characteristics, the structure of the connector 10 is preferable to the modified connectors 10A to 10C unless there is a special reason.
