Referring to Figures 1 and 2 together with Figure 4, first, the positioning part 288 is inserted into the positioning hole 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 part 288. Then, the two screws 89 are screwed into the nuts (not shown) by passing them through the through hole 552 and the through hole 86 of the second object 80, respectively. As a result, the connector 10 is securely fixed to the second object 80.
[0059] Referring to Figures 2 and 4, according to this embodiment, the cross-sections of each positioning portion 288 in the XY plane partially protrude from the cross-section of the positioning hole 88 in the XY plane. Furthermore, each positioning portion 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 thereto. For example, the cross-sections of each positioning portion 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 needed.
[0060] Referring to Figures 8 and 10 in conjunction with Figure 2, the flat bottom 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. As a result, the shell 40 and the additional shell 50 are grounded to the ground pattern 85 and have the same ground potential as each other. The terminal structure 16 (see Figure 11) is covered from above and below by the shell 40 and the additional shell 50, and 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-described structure. However, the present invention is not limited thereto, and the structures of the shell 40 and the additional shell 50 can be modified as needed.
[0061] Referring to Figures 14 and 15, the terminals 30 in this embodiment have the same shape. However, the present invention is not limited thereto.

In this embodiment, the retained 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 thereto. For example, the terminal 30 may be formed by joining a plurality of metal plates. In addition to the above-described portions, the terminal 30 may have other portions.
[0063] Referring to Figures 14 and 15 in conjunction with Figure 7, the retained portion 32 in this embodiment extends straight along the front-rear direction and is held by the retaining portion 22 of the housing 20. The retained portion 32 is embedded in the retaining portion 22. More specifically, the retained portion 32 is completely surrounded by the thick retaining portion 22 in the vertical plane (YZ plane). The first portion 34 extends rearward from the retained portion 32. The first portion 34 is embedded inside the housing 20 except for its top surface and rear end. The second portion 36 extends forward from the retained portion 32. The second portion 36 is mostly located inside the housing portion 14 and partially embedded inside the housing 20.
[0064] The first part 34 of this embodiment has a connected portion 342 and an embedded portion 344.

The upper surface of the connected portion 342 is a plane parallel to the XY plane, is exposed above the base portion 23, and faces the receiving portion 12. The embedded portion 344 extends rearward from the rear end of the connected portion 342 in a curved manner. The embedded portion 344 is embedded inside the base portion 23 except for its rear end. The rear end of the embedded portion 344 protrudes rearward from the base portion 23. Referring to Figure 8, the connected portion 342 is connected to the first object 70. Specifically, 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] Referring to Figures 14 and 15 in conjunction with Figure 7, the second portion 36 of this embodiment has an extension portion 362, a folded portion 364, a support portion 366, a contact portion 38, and a tip portion 368. The second portion 36 is exposed from the housing 20 except for a part of the upper surface of the extension portion 362. The intermediate portion of the second portion 36 in the pitch direction is partially cut out.
[0066] The extension 362 extends forward from the held portion 32. More specifically, the extension 362 extends straight forward from the front end of the held portion 32 along the lower surface of the intervening portion 26 of the housing 20. The folded portion 364 is connected to the front end of the extension 362 and is folded back to the rear. The support portion 366 extends rearward from the folded portion 364. More specifically, the support portion 366 extends straight rearward from the rear end of the folded 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] Referring to Figures 7 and 9, the support portion 366 formed as described above is elastically deformable with its tip 368 as the free end. The contact portion 38 is supported by the support portion 366 and is movable vertically as the support portion 366 elastically deforms. In this embodiment, the contact portion 38 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 separated from the second object 80 (see Figures 8 and 10), the second portion 36 of the terminal 30 is housed in the housing 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] Referring to Figures 8 and 10, the contact portion 38 is pressed against the second object 80 when the connector 10 is fixed to 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 being pressed against it, without using fixing means such as soldering. Therefore, the connector 10 can be removed from the second object 80 simply by removing the screw 89 (see Figure 1).
[0069] The support portion 366 in this embodiment is a cantilever beam and is easily flexible. In addition, the structure of the second portion 36 in this embodiment allows for a longer spring length of the second portion 36 including the support portion 366, and also allows for a larger vertical movement of the contact portion 38. Even if the contact portion 38 moves significantly, the tip 368 moves within the housing portion 14 without hitting other parts 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 have an opening to the front. The contact portion 38 may be located at the front end of the support portion 366. When the connector 10 is away from the second object 80, the contact portion 38 may protrude forward through the opening of the connector 10.
[0071] Each of the terminals 30 in this embodiment has the structure described above. However, the present invention is not limited thereto, and the structure of each of the terminals 30 can be modified as needed. For example, the embedded portion 344, the extension portion 362, the folded portion 364, and the tip 368 may be provided as needed. If the extension portion 362 and the folded portion 364 are not provided, the support portion 366 may extend forward and downward from the front end of the held portion 32.

[0074] Each of the mounting portions 314 in this embodiment is located below the connected portion 342 of the predetermined terminal 306. However, the present invention is not limited thereto. For example, each of the mounting portions 314 may be in the same position as the connected portion 342 of the predetermined terminal 306 in the vertical direction.
[0075] Referring to Figures 8 and 10, the front ends of all cables 70 are received by the receiving portion 12 and connected to the terminals 30, respectively, as will be described below.
[0076] Referring to Figure 13, each discrete cable 702 is connected to a separation terminal 302. That is, terminal 30 includes one or more separation terminals 302, each connected to a discrete cable 702. Each core wire 72 of the discrete cable 702 is fixed and connected to the connection portion 342 of the separation terminal 302 by soldering.

[0078] Each of the predetermined cables 706 is connected to a predetermined terminal 306. That is, terminal 30 includes one or more predetermined terminals 306 corresponding to each predetermined cable 706. Each core wire 72 of the predetermined cable 706 is fixed and connected to the connection portion 342 of the corresponding predetermined terminal 306 by soldering. Each of the ground conductors 76 is mounted on the rear mounting portion 314 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 positioned on both sides of two predetermined terminals 306 in the pitch direction. This structure allows two predetermined cables 706 to be connected. of High-frequency signals can be transmitted to two predetermined terminals 306 via this, and two connecting terminals 304 having ground potential can 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 thereto. For example, the two connecting terminals 304 may be located on either side of a 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 of the shell 40 in this embodiment (see Figure 3) will be described in more detail below.
[0082] Referring to Figures 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 of the connecting portion 44 and the second upper plate portion 43 in the pitch direction are not connected to any part of the shell 40.
[0083] Referring to Figure 11 in conjunction with Figure 7, the first upper plate portion 42 extends along the pitch direction over two or more terminals 30 and covers the first portion 34 of the terminals 30 from above in the vertical direction. In particular, the first upper plate portion 42 in this embodiment covers all of the first portions 34 from above. The second upper plate portion 43 extends along the pitch direction over two or more terminals 30 and covers the second portion 36 of the terminals 30 from above. In particular, the second upper plate portion 43 in this 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 Figure 8, the first upper plate portion 42 of the shell 40, which has a ground potential, covers the receiving portion 12 on which the first portion 34 of the terminal 30 is located from above. The first object 70 is connected to the connected portion 342 of the first portion 34 in the receiving portion 12. Generally, the receiving portion 12 needs to be large enough to accommodate the first object 70. More specifically, the distance between the first upper plate portion 42 and the connected portion 342 needs to be a certain distance. In particular, if the first object 70 is a cable 70, the first upper plate portion 42 needs to be a certain distance from the connected portion 342 in order to prevent a short circuit between the core wire 72 of the first object 70 and the shell 40. According to the prior art, the shell 40 On top The entire plate 41 is formed so as to be separated upward from the terminal 30.
[0085] It has a ground potential. on Even if the plate 41 is separated from the terminal 30, the retained portion 32 of the terminal 30 is covered by an insulator, allowing for a relatively low impedance. The first portion 34 of the terminal 30 is partially exposed to the receiving portion 12, but the ground conductor 76 of the cable 70 is located nearby, allowing for a relatively low impedance. On the other hand, the second portion 36 of the terminal 30 is mostly exposed to the housing portion 14, making it prone to high impedance. According to the prior art, the impedance of the second portion 36 does not match the impedance of the retained portion 32 and the first portion 34, which easily degrades the transmission characteristics.

Furthermore, the second upper plate portion 43 in this embodiment has a flat plate shape without irregularities and extends along the XY plane. However, the present invention is not limited thereto. For example, if the position of the second portion 36 in the vertical direction or the front-to-back direction is not constant, the position of the second upper plate portion 43 in the vertical direction or the front-to-back direction may be adjusted according to the arrangement of the second portion 36. For example, two or more portions with different vertical positions may be formed on the second upper plate portion 43.
[0088] According to this embodiment, the first upper plate portion 42, the connecting portion 44, and the second upper plate portion 43, which extend along the pitch direction, are connected without gaps in the front-to-back direction. This structure makes it easier to improve transmission characteristics. However, the present invention is not limited thereto. For example, two or more connecting portions 44 and two or more second upper plate portions 43 may be formed at necessary locations depending on the arrangement of the second portion 36.
[0089] Referring to Figures 1 and 3, according to the method of forming the connecting portion 44 and the second upper plate portion 43 of this embodiment, the housing 20 is partially exposed to the outside. That is, the housing 20 of this embodiment has one or more visible portions 29 that are exposed to the outside. Each of the visible portions 29 is adjacent to the connecting portion 44, and is at least partially in the same position as the connecting portion 44 in the vertical direction, and ,Ko It is visible from the outside of Necta 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, 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] Referring to Figures 7 and 9, according to this embodiment, the intervening portion 26 of the housing 20 partially covers each of the second portions 36 of the terminal 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 this embodiment, it is easy to reduce the distance between the second upper plate portion 43 and the second portion 36 while preventing short circuits between them. However, the present invention is not limited thereto, and the intervening portion 26 may be provided as needed.

In particular, the first lower plate portion 52 in this 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 portion 342 of the predetermined terminal 306 from below. In particular, the second lower plate portion 53 in this embodiment covers all of the connected portions 342 of the predetermined terminal 306 from below. The second lower plate portion 53 is located above the first lower plate portion 52.
[0095] Referring to Figure 8, the impedance of the connected portion 342 of the first portion 34 of the predetermined terminal 306 tends to be relatively higher than that of the mounting portion 314 on which the ground conductor 76 of the first object 70 is mounted. On the other hand, according to this 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.

[0096] According to this embodiment, the additional connecting portion 54 and the second lower plate portion 53 are provided only below a 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 thereto. For example, the additional connecting portion 54 and the second lower plate portion 53 may be provided below all terminals 30. On the other hand, the additional connecting portion 54 and the second lower plate portion 53 may be provided only as needed.
[0097] In 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. Furthermore, the first lower plate portion 52, the additional connecting portion 54, and the second lower plate portion 53, which extend along the pitch direction, are connected without gaps in the front-rear direction. This structure makes it easier to improve transmission characteristics. However, the present invention is not limited thereto. 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 needed. For example, the second lower plate portion 53 may be formed by partially drawing or embossing the first lower plate portion 52.

[0114] According to this modified example, two sets are provided, each consisting of one second upper plate portion 43C and one connecting portion 44C. ,above The plates 41C are formed by cutting and bending. In each set, the second upper plate portion 43C is connected to the first upper plate portion 42C via a connecting portion 44C. Specifically, each of the connecting portions 44C extends along the front-rear direction. Each of the connecting portions 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 of the second upper plate portions 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 each extend along the pitch direction so as to move closer to each other from the two side portions 45.
[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 each adjacent to the connecting portion 44C. The two visible portions 29C are at least partially in the same position as the connecting portion 44C in the vertical direction, and ,Ko The connector 10C is visible from the outside. The two visible portions 29C are located on the outside in the pitch direction of the two second upper plate portions 43C, respectively. 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] With the above-described structure, the impedances of the first part 34, the second part 36, and the retained part 32 are matched, thereby improving the transmission characteristics. According to this modified example, a compression-type connector 10C capable of improving transmission characteristics can be provided.
[0117] Referring to Figure 3, the second upper plate portion 43 of connector 10 is grounded to the second object 80 (see Figure 1) via the front plate 46 and the additional shell 50. On the other hand, the second upper plate portions 43A (see Figure 18), 43B (see Figure 19), and 43C (see Figure 22) of the modified example described above are not connected to the portion grounded to the second object 80, and instead form a stub on the ground signal transmission path. Therefore, considering the transmission characteristics, the structure of connector 10 is preferable to that of the modified connectors 10A to 10C unless there is a particular reason not to.
