[0005] Patent Document 1: Japanese Patent Application Laid-Open No. 2013-229255 Summary of the Invention
[0006] Problems to be solved by the invention
[0007] The outer shield shell used in this shielded connector can be composed of two parts: a square cylindrical main member surrounding the inner housing and a connecting member crimped to the shield layer of the shielded wire. The main member and the connecting member can be combined by fastening a fixing piece formed at the front end of the connecting member to the outer periphery of the main member.
[0008] When the outer shield shell is constructed as a two-part structure, the fixing piece of the connecting member protrudes from the outer surface of the main member, creating a step on the outer surface of the outer shield shell due to the fixing piece. Therefore, when the terminal module is inserted into the module receiving chamber of the outer shell, the area of the terminal module forward of the fixing piece may wobble, with the fixing piece serving as a fulcrum.

[0011] The shielded connector disclosed herein comprises:
[0012] a housing having a module receiving compartment; and
[0013] The terminal module is inserted into the module receiving chamber from the rear of the housing.
[0014] The terminal module is in a form in which an inner conductor is surrounded by a dielectric body and the dielectric body is surrounded by an outer conductor.
[0015] The outer conductor has a protrusion protruding from the outer surface of the outer conductor at a position rearward of the front end of the outer conductor.
[0016] The inner wall surface constituting the module storage chamber has an opposing inner surface facing the outer surface on which the protrusion is formed.

[0027] [Description of Embodiments of the Present Disclosure]
[0028] First, embodiments of the present disclosure will be described below.
[0029] The shielded connector disclosed herein,
[0030] (1) It comprises: a shell having a module storage chamber; and a terminal module inserted into the module storage chamber from the rear of the shell, the terminal module being in the form of an inner conductor surrounded by a dielectric body and the dielectric body surrounded by an outer conductor, the outer conductor having a protrusion protruding from the outer surface of the outer conductor at a position rearward of the front end of the outer conductor, the inner wall surface constituting the module storage chamber having an opposing inner surface opposite to the outer surface on which the protrusion is formed, a protruding shake eliminating portion being formed on the opposing inner surface, and when the terminal module is inserted into the module storage chamber, the protrusion is arranged rearward of the shake eliminating portion.
[0031] According to the disclosed configuration, when the terminal module is inserted into the module housing, a gap is created between the outer surface of the outer conductor, in front of the protrusion, and the opposing inner surface of the module housing. However, because the protruding anti-sway feature formed in the module housing exists within this gap, the terminal module cannot tilt about the protrusion. This prevents the terminal module from swaying within the housing.
[0032] (2) Preferably, a guide surface is formed at the rear end of the shake eliminating portion, which is inclined relative to the insertion direction of the terminal module into the module storage chamber. According to this configuration, the front end of the terminal module can be prevented from contacting the shake eliminating portion during the insertion process of the terminal module.
[0033] (3) Preferably, the de-swaying portion has a shape whose width tapers toward the protruding direction in a cross section taken perpendicular to the insertion direction of the terminal module. This configuration ensures the strength of the de-swaying portion and reduces sliding resistance between the terminal module and the de-swaying portion during insertion of the terminal module.
[0034] (4) Preferably, the module receiving chamber is provided with an elastically deformable lance for preventing the terminal module inserted into the module receiving chamber from being removed. The lance is located on the side of the terminal module opposite to the opposing inner surface and is capable of elastically pressing the terminal module. With this configuration, the terminal module is held in contact with the sway eliminating portion by the elastic pressing force of the lance, thereby more effectively preventing swaying of the terminal module.
[0035] (5) Preferably, the pair of anti-shake portions are arranged symmetrically with a gap in the width direction of the terminal module. According to this configuration, the terminal module abuts against the pair of anti-shake portions, thereby preventing the terminal module from tilting in the width direction.
[0036] (6) Preferably, an elastic contact portion is formed on the outer surface of the outer conductor to elastically contact a mating member to which the outer conductor is connected, and the deflection elimination portion is located at a position different from that of the elastic contact portion in the width direction of the terminal module. With this configuration, the elastic contact portion does not interfere with the deflection elimination portion during insertion of the terminal module into the module storage chamber. Therefore, an increase in insertion resistance caused by elastic deformation of the elastic contact portion due to interference with the deflection elimination portion can be avoided.
[0037] (7) Preferably, the outer conductor is formed by combining a main body member surrounding the dielectric body and a connecting member having a crimping portion, wherein the crimping portion is connected to the shield layer of the shielded wire, and a fixing piece formed on the connecting member overlaps with the outer surface of the main body member to form the protrusion. According to this configuration, by dividing the outer conductor into two parts, namely the main body member and the connecting member, the shape of each part can be simplified, and the forming process of each part can be simplified.
[0038] (8) In (7), preferably, the main body member includes a square cylindrical portion surrounding the dielectric body and a first covering portion extending rearward from the square cylindrical portion, and the connecting member includes a second covering portion connecting the fixing piece and the crimping portion. When the main body member and the connecting member are combined, the first covering portion and the second covering portion form a cylindrical shielding portion, and the cylindrical shielding portion surrounds the area between the shielding layer and the square cylindrical portion in the inner conductor of the shielded wire. This configuration can prevent leakage of electromagnetic noise between the shielding layer and the square cylindrical portion.
[0039] [Details of the embodiments of the present disclosure]
[0040] [Example 1]
[0041] Reference Figures 1 to 6 The following describes Example 1 of the shielded connector A disclosed herein. The present invention is not limited to these examples, but is intended to include all modifications within the meaning and scope equivalent to the claims. Figures 1 to 3 The oblique left and Figure 5 The left direction in is defined as the front. Figures 1 to 6 The directions shown are defined as upward and downward. Figure 4 、 6 The directions shown are defined as left and right as they are.
[0042] like Figure 3 As shown, the shielded connector A comprises a terminal module 10 and a housing 45 connected to the front end of a shielded wire 60. The shielded wire 60 is a shielded wire in which a pair of inner conductors 61, enclosed by an insulating sheath, are surrounded by a shield layer 62, which is then enclosed by a sheath 63. The shield layer 62 is made of a braided wire. The front ends of the pair of inner conductors 61 are positioned by a clamp 64. The front end of the shield layer 62 forms a folded portion 65 that is folded back rearward and overlaps the outer periphery of the sheath 63. A cylindrical sleeve 66 is installed as a reinforcement member between the outer periphery of the sheath 63 and the folded portion 65 of the shield layer 62.
[0043] The terminal module 10 includes a pair of left and right inner conductors 11, a dielectric body 12 that houses the pair of inner conductors 11, and an outer conductor 15 that surrounds the inner conductors 11 and the dielectric body 12. The rear ends of the pair of inner conductors 11 are connected to a pair of internal conductors 61. The dielectric body 12 is formed by combining a housing member 13 and a cover member 14, forming an overall rectangular parallelepiped shape. The pair of inner conductors 11 are housed within the dielectric body 12, sandwiched between the housing member 13 and the cover member 14.
[0044] The outer conductor 15 is formed by assembling a metal main body member 16 and a metal connecting member 30 which is a separate component from the main body member 16. The main body member 16 is formed by performing a stamping process of bending and hammering a metal plate of a predetermined shape. Figure 2 As shown, the main body member 16 includes a square tube portion 17 , a first covering portion 18 projecting rearward from the rear end of the square tube portion 17 , and a locking portion 19 projecting rearward from the rear end of the first covering portion 18 .
[0045] like Figure 1 、 2 As shown, the square tube portion 17 includes an upper plate portion 20, a lower plate portion 21, and a pair of left and right side plates 22. The left and right side edges of the upper plate portion 20 and the upper ends of the pair of side plates 22 are vertically connected to form angular portions extending in the front-to-back direction. The left and right side edges of the lower plate portion 21 and the lower ends of the pair of side plates 22 are also vertically connected to form angular portions extending in the front-to-back direction. The locking portion 19 protrudes rearward in a cantilevered manner from the widthwise center portion of the rear end edge of the lower plate portion 21.
[0046] A pair of symmetrical elastic contact portions 23 are formed on each of the upper plate 20 and lower plate 21 of the square tube 17. The pair of elastic contact portions 23 are spaced apart in the width direction (left-right direction) of the upper plate 20 and lower plate 21. One elastic contact portion 23 is formed at the center of each of the left and right side plates 22 in the vertical direction. The elastic contact portions 23 protrude outward from the outer surface of each plate 20, 21, and 22. The six elastic contact portions 23 are located only in the area forward of the center of the square tube 17 in the front-to-back direction.
[0047] The elastic contact portion 23 is aligned with the axis 24 of the outer conductor 15 (see Figure 5 ) is parallel to the front and rear directions and is slender. The front and rear ends (length direction) of the elastic contact portion 23 are connected to the plate portions 20, 21, 22 (the forming matrix of the elastic contact portion 23). When the elastic contact portion 23 is viewed from a direction parallel to the outer surface of each plate portion 20, 21, 22 and perpendicular to the length direction of the elastic contact portion 23, the elastic contact portion 23 forms a mountain-shaped bend. The bend portion of the elastic contact portion 23 corresponding to the top of the mountain becomes the opposite side outer conductor 68 (refer to the square tube shape) Figure 5 )'s inner circumferential surface in contact with the contact portion.
[0048] A pair of symmetrical positioning protrusions 27 are formed on the left and right side plates 22 that constitute the square cylindrical portion 17. The pair of positioning protrusions 27 are positioned rearward of the front-to-back center of the square cylindrical portion 17. The first covering portion 18 is continuous across the entire width of the rear end edge of the lower plate 21 and the lower end regions of the rear ends of the left and right side plates 22, forming a curved shape with a recessed top surface. The locking portion 19 extends straight rearward from the left-to-right center of the rear end edge of the first covering portion 18, parallel to the axis 24 of the outer conductor 15.
[0049] like Figure 1 、 2 As shown, the connecting member 30 includes a box-shaped connecting portion 31 with an open lower surface, a second covering portion 38, and an open cylindrical crimping portion 39. The connecting portion 31 includes a flat base portion 32, a pair of symmetrical fixing tabs 33 extending downward from the left and right edges of the base portion 32, and a pair of symmetrical stabilizing portions 34 extending vertically downward from the left and right edges of the base portion 32. A square locking hole 35 is formed in the base portion 32. A locking protrusion 36 is formed at the front edge of the opening of the locking hole 35, protruding toward the outer surface of the base portion 32.
[0050] The fixing piece 33 is connected to the side edge of the base plate portion 32, excluding the front end. Before the connecting member 30 is assembled with the main body member 16, the fixing piece 33 is formed into a flat plate perpendicular to the base plate portion 32. During the process of assembling the connecting member 30 to the main body member 16, the extended end of the fixing piece 33 is bent parallel to the base plate portion 32. The stabilizing portion 34 is connected to the front end of the side edge of the base plate portion 32. A positioning groove 37 is formed between the rear end edge of the stabilizing portion 34 and the front end edge of the fixing piece 33.
[0051] The second covering portion 38 is continuous across the entire width of the rear edge of the base plate portion 32 and the upper end regions of the rear edges of the left and right fixing pieces 33. The second covering portion 38 is curved, opposite to the first covering portion 18, with its lower surface (the side opposite the first covering portion 18) concave. The crimping portion 39 includes a base portion 40 connected to the rear edge of the second covering portion 38 and fastening pieces 41 cantilevered from the left and right edges of the base portion 40.
[0052] When assembling the main member 16 and the connecting member 30, the positioning protrusion 27 and the positioning groove 37 are engaged, and the connecting portion 31 is placed over the rear end of the square tube portion 17. The base plate portion 32 overlaps the outer surface of the upper plate portion 20, and the left and right fixing tabs 33 overlap the outer surfaces of the left and right side plates 22. The engagement of the positioning protrusion 27 and the positioning groove 37 positions the main member 16 and the connecting member 30 in the front-to-back direction. Because the connecting portion 31 is assembled further rearward than the elastic contact portion 23, the base plate portion 32 and the stabilizing portion 34 do not interfere with the elastic contact portion 23.
[0053] Next, bend the lower end portions of the two fixing pieces 33 so that they overlap with the outer surface of the lower plate portion 21. Figure 2 、 5 As shown, the lower end portion of the fixing piece 33 that overlaps with the outer surface of the lower plate portion 21 is formed as a pair of bilaterally symmetrical protrusions 42, which protrude in a stepped manner from the outer surface of the square tube portion 17. The protrusions 42 are located at the rear end portion of the square tube portion 17 and are arranged behind the elastic contact portion 23. Through the above, the main body member 16 and the connecting member 30 are combined and integrated to form the outer conductor 15. The front end side portion of the square tube portion 17 in the main body member 16, where the elastic contact portion 23 is formed, protrudes forward from the front end of the connecting portion 31 of the connecting member 30. At the rear of the square tube portion 17, the first covering portion 18 and the second covering portion 38 form a cylindrical shielding portion 43.
[0054] The dielectric 12 is housed within the square cylindrical portion 17 from behind the outer conductor 15 through the two covering portions 18 and 38. The dielectric 12 houses the inner conductor 11, which is connected to the inner conductor 61. After the dielectric 12 is inserted into the square cylindrical portion 17, the base 40 of the crimping portion 39 and the retaining portion 19 are radially overlapped relative to the outer periphery of the shield layer 62, and the fastening piece 41 is crimped onto the outer periphery of the retaining portion 19 and the folded portion 65. The protruding end of the fastening piece 41 is circumferentially retained by the retaining portion 19. When the crimping portion 39 is crimped to the front end of the shield layer 62 so that electrical contact can be established, the terminal module 10 is connected to the front end of the shielded wire 60.
[0055] When the terminal module 10 and shielded wire 60 are connected, the entire inner conductor 11 is shielded by being surrounded by the square cylindrical portion 17 of the outer conductor 15. The area between the front end of the shield layer 62 and the rear end of the square cylindrical portion 17 in the inner conductor 61 is shielded by being surrounded by the cylindrical shield portion 43. Because the square cylindrical portion 17 is connected throughout its entire circumference by four plate portions 20, 21, and 22, it exhibits high shielding performance. The left and right ends of the first covering portion 18 and the left and right ends of the second covering portion 38 are in seamless contact, providing a higher shielding function than the cylindrical shield portion 43. Therefore, electromagnetic noise generated in the conductive path formed by the inner conductor 61 and the inner conductor 11 between the front end of the shield layer 62 and the front end of the outer conductor 15 does not leak outside the outer conductor 15.
[0056] The housing 45 is a single component made of synthetic resin. Figure 5 As shown, a module storage chamber 46 is formed within the housing 45, extending through the housing 45 in the front-to-back direction. The terminal module 10 is inserted into the module storage chamber 46 from the rear of the housing 45. The module storage chamber 46 comprises a connection space 47 with a square cross-section that opens on the front surface of the housing 45; a retaining space 48 with a square cross-section that connects to the rear of the connection space 47; and a rear space 49 that connects to the rear end of the retaining space 48 and opens on the rear end of the housing 45.
[0057] When the terminal module 10 is inserted into the module housing chamber 46, the portion of the outer conductor 15 forward of the front end of the connecting member 30, i.e., the exposed portion of the square cylindrical portion 17, is housed within the connecting space 47. A fitting space 50 for housing the mating outer conductor 68 is provided between the outer circumference of the square cylindrical portion 17 and the inner circumference of the connecting space 47. The cylindrical shield portion 43 and the crimping portion 39 of the outer conductor 15 are housed within the rear space 49. The coupling portion 31 of the connecting member 30 is housed within the locking space 48.
[0058] The locking space 48 is defined by an upper wall, a lower wall, and a pair of left and right side walls. A lance 52 is formed on the upper wall, extending forward in a cantilevered manner. The lance 52 is elastically deformable in the vertical direction. When the terminal module 10 is inserted into the module storage chamber 46, the upper surface of the base 40 of the connecting portion 31 is closely aligned with the upper wall of the locking space 48, and the lance 52 engages the locking hole 35 and the locking protrusion 36 from behind. The locking of the lance 52 prevents the terminal module 10 from being released from the housing 45.
[0059] When the terminal module 10 is inserted into the module storage chamber 46, the lower surface of the protrusion 42 overlapping with the lower surface of the square tube 17 is placed on the lower wall surface of the locking space 48. Figure 4 、 5As shown, the area of the lower surface of the square tube portion 17 that is forward of the protrusion 42 is opposed to the lower wall surface with a gap S corresponding to the protrusion dimension of the protrusion 42. The lower wall surface of the locking space 48 is the surface that faces the lower surface of the square tube portion 17 on the outer surface of the outer conductor 15 where the protrusion 42 is arranged, and is defined as the opposing inner surface 54 in this first embodiment.
[0060] In the area of the opposing inner surface 54 that is forward of the protrusion 42, there is a gap S between the area and the lower surface of the outer conductor 15. Therefore, the terminal module 10 may rock like a seesaw in the module storage chamber 46 with the front end of the protrusion 42 as a fulcrum. As a countermeasure, a pair of left and right rocking elimination portions 55 are formed on the opposing inner surface 54. The rocking elimination portions 55 are elongated in the front-to-back direction and protrude from the opposing inner surface 54 in the shape of ribs. The rocking elimination portions 55 are arranged at the front end portion of the opposing inner surface 54, in a position forward of the protrusion 42, that is, opposite to the lower surface of the square tube portion 17. By the upper end of the rocking elimination portion 55 abutting against the lower surface of the square tube portion 17, the rocking of the terminal module 10 can be suppressed or prevented.
[0061] like Figure 4 、 6 As shown, when viewing the housing 45 from the front, the anti-shake portion 55 forms a semicircular shape. Specifically, the width of the anti-shake portion 55 is greatest at its lower end, where it connects to the opposing inner surface 54, and gradually decreases toward the projecting direction (upward). The pair of anti-shake portions 55 are arranged symmetrically in the width direction of the module storage chamber 46 and the terminal module 10.
[0062] like Figure 4 As shown, the pair of de-swaying portions 55 are positioned differently from the pair of elastic contact portions 23 formed on the lower plate portion 21 of the terminal module 10 when viewed from the front. Specifically, the pair of de-swaying portions 55 are positioned between the pair of elastic contact portions 23. During insertion of the terminal module 10 into the module receiving chamber 46, the elastic contact portions 23 pass to the sides of the de-swaying portions 55 without interfering with them, and are able to reach a predetermined position (connection space 47) in front of the de-swaying portions 55.
[0063] like Figure 6As shown, the pair of anti-shake portions 55 are located opposite the lance 52 in the direction of elastic deformation (vertical direction) of the lance 52. In other words, the lance 52 and the pair of anti-shake portions 55 are positioned so as to sandwich the terminal module 10 in the vertical direction. In the left-right direction, the pair of anti-shake portions 55 are arranged within the formation range of the lance 52. The terminal module 10 inserted into the module storage chamber 46 is elastically pressed downward (toward the opposing inner surface 54) by the lance 52. This pressing action maintains the lower surface of the square tube 17 in contact with the upper ends of the pair of anti-shake portions 55.
[0064] The shielded connector A of the present embodiment 1 comprises: a housing 45 having a module storage chamber 46; and a terminal module 10 inserted into the module storage chamber 46 from the rear of the housing 45. The terminal module 10 is in a form in which an inner conductor 11 is surrounded by a dielectric 12, and the dielectric 12 is surrounded by an outer conductor 15. The outer conductor 15 has a protrusion 42 that protrudes from the outer surface of the outer conductor 15 at a position rearward of the front end of the outer conductor 15. The inner wall surface constituting the module storage chamber 46 has an opposing inner surface 54. The opposing inner surface 54 is opposed to the outer surface of the outer conductor 15 (the lower surface of the square tube 17) on which the protrusion 42 is formed. A protruding shake elimination portion 55 is formed on the opposing inner surface 54. When the terminal module 10 is inserted into the module storage chamber 46, the protrusion 42 is arranged rearward of the shake elimination portion 55.
[0065] When the terminal module 10 is inserted into the module housing chamber 46, a gap S is created between the outer surface of the outer conductor 15, in front of the protrusion 42, and the opposing inner surface 54 of the module housing chamber 46 due to the protrusion 42. However, because the protruding anti-shake portion 55 formed in the module housing chamber 46 is located within this gap S, the terminal module 10 cannot tilt about the protrusion 42. This prevents the terminal module 10 from shaking within the housing 45.
[0066] A guide surface 56 is formed at the rear end of the sway elimination portion 55. The guide surface 56 is inclined relative to the insertion direction of the terminal module 10 into the module storage chamber 46. During the insertion of the terminal module 10, the front end of the terminal module 10 does not contact the sway elimination portion 55, but slides on the guide surface 56. As a result, the terminal module 10 can be inserted into the module storage chamber 46 without any obstruction. The pair of sway elimination portions 55 are arranged in a symmetrical positional relationship with a gap in the width direction of the terminal module 10. The terminal module 10 is abutted against the pair of sway elimination portions 55, thereby preventing the terminal module 10 from tilting in the width direction.
[0067] In a cross section taken perpendicular to the insertion direction of the terminal module 10, the de-swaying portion 55 has a semicircular shape whose width tapers toward the direction in which it protrudes from the opposing inner surface 54. The semicircular cross-sectional shape of the de-swaying portion 55 ensures its strength and reduces sliding resistance between the terminal module 10 and the de-swaying portion 55 during insertion of the terminal module 10.
[0068] The module receiving chamber 46 is provided with an elastically deformable lance 52 for preventing the terminal module 10 inserted into the module receiving chamber 46 from being removed. The lance 52 is positioned on the opposite side of the terminal module 10 from the opposing inner surface 54 and elastically presses the terminal module 10. The elastic pressing force of the lance 52 holds the terminal module 10 in contact with the anti-sway portion 55, effectively preventing the terminal module 10 from swaying.
[0069] The outer surface of the outer conductor 15 is formed with an elastic contact portion 23 that elastically contacts the mating member (the mating outer conductor 68) to which the outer conductor 15 is connected. The play reducing portion 55 is positioned at a different position from the elastic contact portion 23 in the width direction of the terminal module 10. Therefore, during insertion of the terminal module 10 into the module housing chamber 46, the elastic contact portion 23 does not interfere with the play reducing portion 55. This prevents an increase in insertion resistance caused by elastic deformation of the elastic contact portion 23 due to interference with the play reducing portion 55.
[0070] The outer conductor 15 is formed by combining a main body member 16 surrounding the dielectric body 12 and a connecting member 30 having a crimping portion 39. The crimping portion 39 is connected to the shield layer 62 of the shielded wire 60. The fixing piece 33 formed on the connecting member 30 is bent and overlapped with the outer surface of the main body member 16 to form a protrusion 42. With this structure, by dividing the outer conductor 15 into two components, the main body member 16 and the connecting member 30, the shapes of each component 16 and 30 can be simplified, and the molding process of each component 16 and 30 can be simplified.
[0071] The main body member 16 includes a square cylindrical portion 17 that surrounds the dielectric body 12, and a first covering portion 18 that extends rearward from the square cylindrical portion 17. The connecting member 30 includes a second covering portion 38 that connects the fixing piece 33 and the crimping portion 39. When the main body member 16 and the connecting member 30 are combined, the first covering portion 18 and the second covering portion 38 form a cylindrical shielding portion 43. The cylindrical shielding portion 43 surrounds the area between the shielding layer 62 of the inner conductor 61 of the shielded wire 60 and the square cylindrical portion 17. This configuration prevents electromagnetic noise from leaking between the shielding layer 62 and the square cylindrical portion 17.
[0072] [Other embodiments]
[0073] The present invention is not limited to the embodiments described above and illustrated in the drawings, but is presented in the claims. The present invention is intended to include all modifications within the meaning and scope of the claims, including the following embodiments.
[0074] In the first embodiment, the cross-sectional shape of the shake eliminating portion is semicircular, but the cross-sectional shape of the shake eliminating portion may be trapezoidal.
[0075] In the first embodiment, the cross-sectional shape of the shake eliminating portion is a shape in which the width narrows toward the protruding direction.
