[0025] [Description of embodiments of this disclosure]

[0026] First, the implementation methods of this disclosure are listed and explained.

[0027] (1) The connector of this disclosure includes a first connector and a second connector capable of mating with each other. The first connector has a first inner conductor, a first outer conductor covering the outer periphery of the first inner conductor, a first outer conductor cover covering the outer periphery of the first outer conductor, and a first dielectric material disposed between the first inner conductor and the first outer conductor. The second connector has a second inner conductor, a second outer conductor covering the outer periphery of the second inner conductor, a second outer conductor cover covering the outer periphery of the second outer conductor, and a second dielectric material disposed between the second inner conductor and the second outer conductor. The second outer conductor has a second outer conductor body portion disposed between the second dielectric and the second outer conductor cover, and a second outer conductor connecting portion radially overlapping the first outer conductor. The first outer conductor has a first outer conductor body portion disposed between the first dielectric and the second outer conductor cover, a first outer conductor connecting portion covering the outer periphery of the second outer conductor connecting portion and contacting the second outer conductor connecting portion, and a necked section from the first outer conductor connecting portion to the first outer conductor body portion. The first outer conductor cover and the second outer conductor cover have the same shape.

[0028] In this way, when the first outer conductor cover and the second outer conductor cover have the same shape, they can be shared between the first connector and the second connector, thus reducing costs. In particular, with the above configuration, by providing a necking between the first outer conductor connecting portion and the first outer conductor body portion, the first outer conductor body portion and the second outer conductor body portion can be set to have the same or nearly the same diameter. Therefore, it is easy to set the first outer conductor cover and the second outer conductor cover to have the same shape.

[0029] (2) Preferably, the first dielectric has a side dielectric and a side dielectric that can be joined together. The side dielectric has a base wall, opposing surfaces that intersect the base wall and are opposite to each other, and a cavity formed between the opposing opposing surfaces to receive the first inner conductor. The other side dielectric closes the opening side that is opposite to the base wall. A press-in protrusion that contacts the first inner conductor is formed on the opposing surface of the side dielectric.

[0030] When the first outer conductor cover and the second outer conductor cover are shared between the first connector and the second connector, the length of the first dielectric body can sometimes be insufficiently ensured due to the configuration relationship of the first outer conductor cover and the second outer conductor cover during mating. As a result, the first inner conductor may be unstablely housed within the cavity of one side of the dielectric body. In this regard, according to the above configuration, since the press-in protrusion formed on the opposing surface contacts the first inner conductor, the first inner conductor can be stably housed within the cavity.

[0031] (3) Preferably, the press-in protrusion forms a rib in the opposing surface that extends linearly from the opening side toward the base wall.

[0032] When the press-in protrusion is formed in this way, the first inner conductor can be easily inserted into the cavity by lowering it from the opening side toward the base wall.

[0033] (4) Preferably, the first inner conductor is a male terminal having a cylindrical terminal body housed in the cavity and a tab protruding from the terminal body and disposed outside the dielectric body on one side.

[0034] When the first inner conductor is a male terminal, simply lowering the first inner conductor from the opening side toward the base wall and inserting the terminal body into the cavity eliminates the possibility of the tab cutting away the resin of the dielectric. As a result, resin adhesion to the tab is prevented, ensuring reliable connection between the tab and the second inner conductor.

[0035] [Details of the embodiments of this disclosure]

[0036] The following is a reference to the appendix. Figure 1 Specific examples of embodiments of this disclosure will be described below. Furthermore, the invention is not limited to these examples, but is intended to include all modifications within the meaning and scope of the claims, as indicated by the claims.

[0037] Regarding the connector in this embodiment, an example is a shielded connector that connects to the end of the cable 23 used for transmitting communication signals. For example... Figure 1As shown, the connector includes a first connector 10 and a second connector 11 that can be mated with each other. The first connector 10 is a male connector and has a first inner conductor 13 as a male terminal. The second connector 11 is a female connector and has a second inner conductor 14 as a female terminal.

[0038] The first connector 10, in addition to the first inner conductor 13, also includes a first dielectric 15, a first outer conductor 16, a first outer conductor cover 17, and a first housing 18. Similarly, the second connector 11, in addition to the second inner conductor 14, also includes a second dielectric 19, a second outer conductor 21, a second outer conductor cover 17, and a second housing 22. Furthermore, as described later, the first outer conductor cover 17 and the second outer conductor cover 17 have the same shape and can be reused; therefore, they are marked with a common reference numeral 17. Additionally, in the following description, regarding the front-back direction, the faces of the first connector 10 and the second connector 11 facing each other at the start of engagement are referred to as the front side. The vertical direction is excluded... Figure 8 and Figure 9 The vertical direction of all other figures is used as the reference.

[0039] like Figure 2 and Figure 3 As shown, the cable 23 includes two wires 24 consisting of two twisted pairs, a shield 25 consisting of braided wires covering the outer circumference of the wires 24, and an insulating sheath 26 covering the outer circumference of the shield 25. At the front end of the cable 23, the sheath 26 and the shield 25 are removed, exposing the two wires 24. Behind the exposed wires 24 in the cable 23, the shield 25, which protrudes from the end of the sheath 26, is folded back to the front end of the sheath 26. The two wires 24 protruding from the end of the sheath 26 are held by a clamp 28 (see reference). Figure 9 In addition, cables 23 of the same diameter are connected to each other at connector 10 and connector 11.

[0040] <Second Inner Conductor>

[0041] The second inner conductor 14 is formed by bending a conductive metal plate, etc. For example... Figure 3 As shown, the second inner conductor 14 has a cylindrical terminal connection portion 29 and a second wire connection portion 31 connected to the rear of the terminal connection portion 29. (As shown...) Figure 1 As shown, the terminal connection portion 29 contacts the tab 52 of the first inner conductor 13 (described later) for electrical connection when the first connector 10 and the second connector 11 are engaged. The second wire connection portion 31 is electrically connected by crimping the core wire at the front end of the wire 24, and is mechanically connected by crimping the sheath of the wire 24. Two second inner conductors 14 are provided in the second connector 11 corresponding to the two sheathed wires.

[0042] <Second Dielectric>

[0043] The second dielectric 19 is formed into a rectangular parallelepiped shape that is longer in the front-to-back direction using an insulating synthetic resin material. Details of the second dielectric 19 are omitted. It is formed by combining two components together in the vertical direction. Inside the second dielectric 19, two second inner conductors 14 connected to the wire 24 are housed in a configuration that is arranged in the width direction.

[0044] <Second outer conductor>

[0045] The second outer conductor 21 is formed by bending a conductive metal plate, etc. For example... Figure 4 As shown, the second outer conductor 21 has a rectangular fitting tube portion 32 that is long in the front-to-back direction, and a second shielding connection portion 33 that is connected to the shielding body 25 of the cable 23.

[0046] The second dielectric 19 is inserted into the fitting sleeve portion 32 from the rear. When the second dielectric 19 is housed within the fitting sleeve portion 32, the second inner conductor 14 is electrically insulated from the fitting sleeve portion 32 by the second dielectric 19. A second outer conductor connection portion 34 is formed at the front end of the fitting sleeve portion 32, which radially overlaps with the first outer conductor 16 on the opposite side (see reference). Figure 1 An elastic contact portion 35, capable of elastic deformation, is formed in the second outer conductor connection portion 34 to contact the first outer conductor 16. The elastic contact portion 35 is formed by cutting and punching out the four walls of the fitting cylinder portion 32.

[0047] The fitting sleeve portion 32 has a second outer conductor body portion 36, which is covered by the second outer conductor cover 17, located rearward of the second outer conductor connection portion 34. The second outer conductor body portion 36 is connected to the rear of the second outer conductor connection portion 34 with the same diameter without any steps. In addition, the second outer conductor body portion 36 has a second dielectric retaining portion 37 for retaining the second dielectric 19 and a second cover retaining portion 38 for retaining the second outer conductor cover 17.

[0048] The second shielding connection portion 33 is formed into a plate shape extending rearward from the lower rear edge of the fitting cylinder portion 32. For example... Figure 1 As shown, the second shielding connection part 33 is disposed below the shielding body 25 and is connected to the shielding body 25 by the pressing force of the second outer conductor cover 17.

[0049] <Second outer conductor cover>

[0050] The second outer conductor cover 17 is formed by bending a conductive metal plate, etc. For example... Figure 5 As shown, the second outer conductor cover 17 has a flat top plate portion 39, a pair of side plate portions 41 protruding downward from both ends of the top plate portion 39 in the width direction, and a shielding cylinder portion 42 disposed behind the top plate portion 39 and each side plate portion 41. Furthermore, for convenience, Figure 2 , Figure 3 as well as Figure 5 The shielding cylinder portion 42 shown is in its deformed form after being pressed against the shielding body 25 of the cable 23. More precisely, the shielding cylinder portion 42 is formed as an open cylinder before deformation. Each side plate portion 41 has a locking groove 43 into which the second cover locking portion 38 is inserted. Furthermore, the second outer conductor cover 17 has a pair of opposing plate portions 44 protruding inward in the width direction from the lower rear end of each side plate portion 41. Figure 5 (Only one is shown in the image).

[0051] The second outer conductor body 36 is disposed inside the top plate 39, each side plate 41, and each opposing plate 44. It is positioned and held in place by engaging the second cover locking part 38 with the locking groove 43. Figure 11 A square opening 45 is formed in the top plate portion 39, and a housing locking protrusion 46 is curved at the leading edge of the opening 45.

[0052] Although not shown, the shielding cylinder portion 42 is crimped and fixed to the shielding body 25 of the cable 23 with its end edges interlocking in a concave-convex shape when the shielding body 25 is positioned inside. The second shielding connection portion 33 is arranged between the shielding cylinder portion 42 and the shielding body 25 (see reference). Figure 1 ).

[0053] <Second Shell>

[0054] The second shell 22 is made of synthetic resin, such as Figure 1 As shown, a second module storage section 47 extends through the front-rear direction. A second spear-shaped portion 48 is formed protruding forward on the upper surface of the rear inner wall of the second module storage section 47. The second spear-shaped portion 48 is elastically deformable in the up-down direction.

[0055] The second module 49, which is assembled from the second inner conductor 14, the second dielectric 19, the second outer conductor 21, and the second outer conductor cover 17, is housed in the second module housing 47. When the second module 49 is housed in the second module housing 47, the second spear-shaped portion 48 is inserted into the opening hole 45 and locked with the housing locking protrusion 46. A locking arm 51 capable of locking the first housing 18 is formed on the upper wall of the second housing 22.

[0056] <First Inner Conductor>

[0057] The first inner conductor 13 is formed by bending a conductive metal plate, etc. For example... Figure 2As shown, the first inner conductor 13 has a pin-shaped tab 52, a cylindrical terminal body 53 connected to the rear of the tab 52, and a first wire connection portion 54 connected to the rear of the terminal body 53. The tab 52, in its engaged state, is inserted into and connected to the terminal connection portion 29 of the second inner conductor 14. The first wire connection portion 54 is electrically connected to the core wire at the front end of the wire 24 by crimping, and mechanically connected to the sheath of the wire 24 by crimping. Two first inner conductors 13 are provided in the first connector 10, corresponding to the two sheathed wires.

[0058] <First Dielectric>

[0059] The first dielectric 15 is formed into a rectangular parallelepiped shape that is longer in the front-to-back direction using an insulating synthetic resin material. The diameter (height and width) of the first dielectric 15 is set to be the same as the diameter of the second dielectric 19.

[0060] like Figure 2 As shown, the first dielectric 15 has a one-sided dielectric 55 and a other-sided dielectric 56 that can be joined together in the vertical direction. The one-sided dielectric 55 is disposed above the other-sided dielectric 56. Figure 7 As shown, one side dielectric 55 has a flat base wall 57, a pair of side walls 58 protruding downward from both ends of the base wall 57 in the width direction, and an inter-electrode wall 59 protruding downward from the base wall 57 between the pair of side walls 58.

[0061] One dielectric 55 has a pair of cavities 61 separated in the width direction by an inter-electrode wall 59 between a pair of sidewalls 58. A base wall 57 closes the upper surface of each cavity 61. The lower surface of each cavity 61 is open and is closed by the other dielectric 56 assembled to the one dielectric 55. A first inner conductor 13 is inserted into the cavity 61 from below (actually above) as shown in the figure. A tapered guide surface 62 is formed at the lower end of each sidewall 58 to guide the first inner conductor 13. A guide surface 62 is also formed on the inter-electrode wall 59.

[0062] like Figure 8As shown, the front portion of the inter-electrode wall 59 is thicker in the width direction compared to the rear portion. One side dielectric 55 has multiple press-in protrusions 64 on the opposing surfaces 63 of the front portion of the inter-electrode wall 59 and the sidewall 58. Each press-in protrusion 64 protrudes into the cavity 61 at the same position in the front-rear direction in each opposing surface 63, and a pair is arranged at intervals in the front-rear direction. Specifically, each press-in protrusion 64 is formed as a rib extending in the vertical direction, with an arc-shaped cross-section. The distance between the apexes of the opposing press-in protrusions 64 in the width direction is set to be smaller than the width dimension of the terminal body 53 of the first inner conductor 13. The upper end of each press-in protrusion 64 is connected to the base wall 57. The lower end of each press-in protrusion 64 is continuously tapered in the sidewall 58 and the guide surface 62. Furthermore, no structure corresponding to the press-in protrusions 64 is provided on the second dielectric 19.

[0063] like Figure 2 and Figure 9 As shown, the other dielectric 56 has a covering wall 65 that closes the opening on the lower surface of the dielectric 55 on one side, and a pair of locking walls 66 that protrude upward from both ends of the covering wall 65 in the width direction. Each locking wall 66 can elastically deform and lock with the dielectric 55 on one side, keeping the dielectric 55 on one side and the dielectric 56 on the other side in a combined state.

[0064] <First Outer Conductor>

[0065] The first outer conductor 16 is formed by bending a conductive metal plate, etc. For example... Figure 6 As shown, the first outer conductor 16 has a rectangular cylindrical body 67 that is long in the front-to-back direction and a first shielding connection portion 68 that is connected to the shielding body 25 of the cable 23.

[0066] The front part of the main body cylindrical portion 67 is formed into a large-diameter first outer conductor connecting portion 69, on which the second outer conductor connecting portion 34 is disposed. The elastic contact portion 35 of the second outer conductor connecting portion 34 is in conductive contact with the inner surface of the first outer conductor connecting portion 69.

[0067] The rear portion of the main body 67 is formed into a first outer conductor main body 71 with a smaller diameter than the first outer conductor connecting portion 69. The diameter (height and width) of the first outer conductor main body 71 is set to be the same as the diameter of the second outer conductor main body 36. A first dielectric 15 is inserted and housed in the first outer conductor main body 71 from the rear. The first inner conductor 13 is electrically insulated relative to the main body 67 by means of the first dielectric 15. In addition, the first outer conductor main body 71 has a first dielectric locking portion 72 for locking the first dielectric 15 and a first cover locking portion 73 for locking the first outer conductor cover 17.

[0068] The main body cylindrical portion 67 has a tapered neck 74 between the first outer conductor connecting portion 69 and the first outer conductor main body portion 71, which tapers from the rear end of the first outer conductor connecting portion 69 to the front end of the first outer conductor main body portion 71. That is, the neck 74 is square towards the rear and tapers at the top. The diameter of the first outer conductor main body portion 71 is set based on the inclination angle and length of the neck 74.

[0069] The first shielding connection portion 68 is formed in the shape of a plate extending rearward from the lower rear edge of the main body cylindrical portion 67. For example... Figure 1 As shown, the first shielding connection part 68 is disposed below the shielding body 25 and is connected to the shielding body 25 by the pressing force of the first outer conductor cover 17.

[0070] <First Outer Conductor Cover>

[0071] like Figure 5 As shown, the first outer conductor cover 17 and the second outer conductor cover 17 have the same shape and size, and have a top plate portion 39, a side plate portion 41, an opposing plate portion 44, and a shielding cylinder portion 42. In the case of the first outer conductor cover 17, the locking groove 43 locks into the first cover locking portion 73 of the first outer conductor 16 (see reference). Figure 10 The housing locking protrusion 46 engages with the first spear-shaped portion 76 of the first housing 18 (described later). Furthermore, as... Figure 1 As shown, the shielding cylinder 42 clamps the first shielding connection 68 in the middle and presses it into connection with the shielding body 25 of the cable 23.

[0072] In this embodiment, the first outer conductor cover 17 and the second outer conductor cover 17 are used interchangeably and are shared as one outer conductor cover between the first connector 10 and the second connector 11.

[0073] <First Shell>

[0074] The first shell 18 is made of synthetic resin, such as Figure 1 As shown, a first module housing 75 extends through the front-to-back direction. A first spear-shaped portion 76, capable of elastic deformation, protrudes forward from the upper surface of the rear inner wall of the first module housing 75. The first module 77, assembled from the first inner conductor 13, the first dielectric 15, the first outer conductor 16, and the first outer conductor cover 17, is housed in the first module housing 75. The first module 77 is engaged with the first spear-shaped portion 76. Figure 1 and Figure 2 As shown, the front part of the first housing 18 is formed as a large-diameter cover 78 that is larger than the rear part. The second housing 22 is fitted into the cover 78.

[0075] <Connector assembly steps and mating structure>

[0076] When module 77 is assembled, as follows Figure 8 As shown, the first inner conductor 13 is housed in the cavity 61 of the dielectric 55 on one side. The first inner conductor 13 is induced by the guide surface 62 while extending from the opening side of the cavity 61 ( Figure 8 The first inner conductor 13 (outer side of the paper) descends towards the base wall 57 along each pressing protrusion 64. Thus, the terminal body 53 of the first inner conductor 13 is inserted into the cavity 61. The tab 52 of the first inner conductor 13 does not contact the dielectric 55 on one side, but is positioned protruding forward of the dielectric 55 on one side. Therefore, it is possible to prevent the tab 52 from cutting away the resin of the dielectric 55 on one side, and to prevent the resin sheet of the dielectric 55 on one side from adhering to the surface of the tab 52. Each pressing protrusion 64 contacts both sides of the terminal body 53. Each pressing protrusion 64 is in a state where its apex side is pressed by the terminal body 53 of the first inner conductor 13. Thus, the terminal body 53 is held from both sides in the width direction by each pressing protrusion 64, suppressing the shaking of the first inner conductor 13 within the cavity 61.

[0077] In this embodiment, because the first outer conductor cover 17 and the second outer conductor cover 17 are shared, in the fitted state, the first outer conductor cover 17 becomes a structure closer to the second outer conductor cover 17 than in the conventional type, which sometimes cannot adequately ensure the front-to-back length of the first dielectric 15. Therefore, there is a possibility that the first inner conductor 13 may tilt or be unstablely housed within the cavity 61. However, because the first inner conductor 13 is suppressed from wobbling within the cavity 61 by the respective pressing protrusions 64, a stable housed state within the cavity 61 can be achieved.

[0078] Then, as Figure 9 As shown, the assembly is completed by covering one side dielectric body 55 with the other side dielectric body 56. This more stably holds the first inner conductor 13 within the first dielectric body 15. Next, the first dielectric body 15 is inserted into the first outer conductor 16 from the rear. The first dielectric body 15 is secured within the first outer conductor 16 by engaging with the first dielectric body locking portion 72. At this time, the first dielectric body 15 is disposed within the first outer conductor body portion 71, and the tab 52 of the first inner conductor 13 is configured to protrude into the first outer conductor connecting portion 69.

[0079] Next, the first outer conductor cover 17 is assembled to the first outer conductor body 71, and the shielding cylinder 42 and the first shielding connection 68 are pressed together and connected to the shielding body 25 of the cable 23. Thus, Figure 10 The assembly of the first module 77 shown is complete. The first module 77 is inserted into the first module receiving portion 75 of the first housing 18 from the rear. The first module 77 is secured to the first module receiving portion 75 of the first housing 18 by engaging the housing locking protrusion 46 with the first spear-shaped portion 76 (see reference). Figure 1The first outer conductor connection portion 69 is configured to protrude into the cover portion 78. With the above, the assembly of the first connector 10 is completed. The second connector 11 is also assembled using the same steps as the first connector 10.

[0080] The first connector 10 and the second connector 11 are engaged from a mutually facing position. The first housing 18 is locked by the locking arm 51 of the second housing 22, thereby maintaining the first connector 10 and the second connector 11 in the engaged state. Figure 1 As shown, in the mating state, the second outer conductor connection portion 34 is inserted inside the first outer conductor connection portion 69, and the first outer conductor connection portion 69 and the second outer conductor connection portion 34 are arranged to overlap radially. The first outer conductor 16 and the second outer conductor 21 are connected by contact between the elastic contact portions 35 of the second outer conductor connection portion 34 and the inner surface of the first outer conductor connection portion 69. In this embodiment, the first inner conductor 13 and the second inner conductor 14 are completely covered by the first outer conductor 16, the first outer conductor cover 17, the second outer conductor 21, and the second outer conductor cover 17 without gaps, thus preventing noise from intruding from the outside and preventing noise leakage to the outside. Therefore, the shielding performance can be improved.

[0081] Furthermore, in this embodiment, the first outer conductor body portion 71 and the second outer conductor body portion 36 have the same diameter. In the mating state, the outer surfaces of the first outer conductor body portion 71 and the second outer conductor body portion 36 are arranged in a manner that forms a virtual cylinder with the same diameter continuously in the front-to-back direction. Therefore, impedance confusion can be suppressed between the first connector 10 and the second connector 11, and impedance matching can be achieved.

[0082] As described above, according to this embodiment, by distributing a necking 74 between the first outer conductor connecting portion 69 and the first outer conductor main body portion 71, the first outer conductor main body portion 71 and the second outer conductor main body portion 36 can be configured to have the same diameter. Therefore, the first outer conductor cover 17 and the second outer conductor cover 17 can be easily configured to have the same shape.

[0083] Furthermore, even if the front-to-back length of the first dielectric 15 cannot be fully guaranteed, the first inner conductor 13 can be stably housed in the cavity 61 because a plurality of press-in protrusions 64 are formed on one side of the dielectric 55 that contact the terminal body 53 of the first inner conductor 13.

[0084] Furthermore, by lowering the first inner conductor 13 from above towards the base wall 57 from the opening side, the terminal body 53 is inserted into the cavity 61, thereby ensuring good contact between each press-in protrusion 64 and the terminal body 53 of the first inner conductor 13. Further, the tabs 52 of the first inner conductor 13 are disposed outside the first dielectric 15 and do not contact the first dielectric 15 during insertion into the cavity 61. Therefore, resin from the first dielectric 15 can be prevented from adhering to the tabs 52, ensuring reliable connection between the tabs 52 and the second inner conductor 14.

[0085] [Other embodiments of this disclosure]

[0086] The embodiments disclosed herein should be considered illustrative in all respects, and not restrictive.

[0087] As another implementation, the first outer conductor body and the second outer conductor body do not necessarily have to be set to the same diameter, and their diameters can be different within the scope of realizing the commonality of the first outer conductor cover and the second conductor cover.

[0088] As another implementation, the press-in protrusion may also be provided on the second dielectric body in addition to the first dielectric body.

[0089] In another embodiment, the first connector may also be a female connector with the female terminal as the first inner conductor.
