Description

[Technical field]

[0001] The present disclosure relates to a shielding connector. [State of the art]

[0002] Patent literature 1 discloses a shielding connector configured or constructed by inserting a connection module, which is connected to a shielded cable, into an outer housing. The connection module is configured by including a receiving or socket connector in an inner housing, and the inner housing is covered by an outer shielding shell or casing. [Bibliography][Patent Literature]

[0003] Patent literature 1: Japanese, unexamined patent publication no. 2013-229255 [Summary of the invention][Problem that the invention seeks to solve]

[0004] An outer shielding shell used in a shielding connector of this type can consist of two components: a body member in the form of a rectangular or right-angled tube for surrounding an inner housing, and a connecting element for crimping onto a shielding layer of a shielded cable. The body member and the connecting element can be joined by crimping a fixing or fastening piece, formed on a front end of the connecting element, onto the outer circumference of the body member.

[0005] If the outer shielding shell has a two-component structure, the fixing or fastening element of the connecting link protrudes from the outer surface of the body member, and a step is formed on the outer surface of the outer shielding shell by the fixing element. Thus, when a connection module is inserted into a module receiving chamber of an outer housing, a region of the connection module in front of the fixing element can vibrate or rattle with the fixing element, acting as a pivot point.

[0006] A shielding connector of the present disclosure was completed based on the above situation and aims to prevent the shaking or rattling of a connection module in a housing. [Means to solve the problem]

[0007] The present disclosure relates to a shield connector comprising a housing which includes a module receiving chamber, and a connection module which is to be inserted into the module receiving chamber from the rear of the housing, wherein the connection module is configured such that an inner conductor is surrounded by a dielectric and the dielectric is surrounded by an outer conductor, the outer conductor includes a projecting section which projects from a position behind a front end of the outer conductor onto or at an outer surface of the outer conductor, an inner wall surface which represents the module receiving chamber, and an inner surface facing the outer surface which is directed towards the outer surface.The facing inner surface is formed with a projecting section, which is designed with the protruding section, and the protruding section is arranged behind the play-eliminating section when the connection module is inserted into the module receiving chamber. [Effect of the invention]

[0008] According to the present disclosure, it is possible to prevent the rattling or shaking of a connection module in a housing.

Fig. Figure 2 is a perspective view of the connection module, seen obliquely from below. Fig. Figure 3 is a perspective exploded view of a shielding connector.

[Embodiments of the invention][Description of embodiments of the present disclosure]

[0009] First, embodiments of the present disclosure are listed and described.

[0010] (1) A shield connector of the present disclosure is provided with a housing which includes a module receiving chamber and a connection module which is to be inserted into the module receiving chamber from the rear of the housing, wherein the connection module is configured such that an inner conductor is surrounded by a dielectric and the dielectric is surrounded by an outer conductor, the outer conductor includes a projecting section which projects from a position behind a front end of the outer conductor onto or at an outer surface of the outer conductor, an inner wall surface which represents the module receiving chamber, and an inner surface facing the outer surface.The facing inner surface is formed with a projecting section, which is designed with the protruding section, and the protruding section is arranged behind the play-eliminating section when the connection module is inserted into the module receiving chamber.

[0011] According to the configuration described in this disclosure, a gap is formed, due to the presence of the projecting section, between a region in front of the projecting section on the outer surface of the outer conductor and the facing inner surface of the module receiving chamber when the connection module is inserted into the module receiving chamber. However, because the projecting section, which eliminates play, retraction, or counter-movement and is formed in the module receiving chamber, is present in this gap, the connection module is not tilted with the projecting section acting as a pivot point. In this way, vibration or rattling of the connection module within the housing can be prevented.

[0012] (2) Preferably, a rear end part of the clearance-eliminating section is designed with a leading surface which is inclined with respect to the insertion direction of the connection module into the module receiving chamber. According to this configuration, the front end of the connection module can be prevented from contacting or striking the clearance-eliminating section during an insertion process of the connection module.

[0013] (3) Preferably, the clearance-eliminating section is shaped to become narrower in a projecting direction in a cross-section of the clearance-eliminating section that is cut perpendicular to the insertion direction of the connection module. According to this configuration, sliding resistance between the connection module and the clearance-eliminating section during the insertion process of the connection module can be reduced, while ensuring the strength or rigidity of the clearance-eliminating section.

[0014] (4) Preferably, the module receiving chamber is designed with a resiliently deformable locking lance for retaining the connection module which is inserted into the module receiving chamber, and the locking lance is arranged transversely across the connection module on one side opposite the facing inner surface and is capable of resiliently pressing or pushing the connection module. According to this configuration, since the connection module is held in contact with the clearance-eliminating section by a resilient pressing or pushing force of the locking lance, vibration or rattling of the connection module can be more effectively prevented.

[0015] (5) Preferably, a pair of the backlash-eliminating sections is arranged in a symmetrical positional relationship, while being spaced apart from each other in a width direction of the connection module. According to this configuration, the connection module can be prevented from being or becoming inclined in the width direction by coming into contact with the pair of backlash-eliminating sections.

[0016] (6) Preferably, the outer surface of the outer conductor is formed with a restorable contact section configured to restorably contact a matching or tuned link to be connected to the outer conductor, and the clearance-eliminating section is arranged at a position different from the restorable contact section in a width direction of the connection module. According to this configuration, the restorable or elastic contact section does not interact with the clearance-eliminating section during the insertion of the connection module into the module receiving chamber. Therefore, an increase in insertion resistance due to restorable deformation of the restorable contact section caused by contact with the clearance-eliminating section can be avoided.

[0017] (7) Preferably, the outer conductor is configured or constructed by combining a body member for surrounding the dielectric and a connecting member, which includes a crimping section to be connected to a shielding layer of a shielded cable, and the projecting section is formed by placing a fixing or securing piece, which is formed on or attached to the connecting member, on an outer surface of the body member. According to this configuration, the simplification of the shape or form of each member, the simplification of a forming step of each member, and the like, can be achieved by dividing the outer conductor into two components, which include the body member and the connecting member.

[0018] (8) In (7), the body member preferably comprises a rectangular or right-angled tube section for surrounding the dielectric and a first covering section extending backward from the rectangular tube section. The connecting member comprises a second covering section that couples the fixing section and the crimping section. When the body member and the connecting member are joined, a tubular shielding section is formed by the first covering section and the second covering section. The tubular shielding section surrounds a region of an internal conductor of the shielded cable between the shielding layer and the rectangular tube section. According to this configuration, the leakage or escape of electromagnetic noise between the shielding layer and the rectangular or right-angled tube section can be prevented. [Details of the embodiment of the present disclosure][Emphasis]

[0019] A specific embodiment of a shielding connector A of the present disclosure is described below with reference to Fig. 1 to Fig. 6 described. It should be noted that the present invention is not limited to these illustrations and representations and is intended to be represented by claims, including all modifications in the scope of claims and in the meaning and scope of equivalents. In this embodiment, a direction obliquely to the left is shown in Fig. 1 to Fig. 3 and a left-hand direction in Fig. 5 is defined as a forward direction pertaining to a forward-backward direction. An upper and lower side, which in Fig. 1 to Fig. Figure 6 shows these sides as being directly defined as a top and bottom side in a vertical direction. A left and right side, which are shown in Fig. 4 and Fig. Figure 6 is directly defined as a left and right side, pertaining to a lateral direction.

[0020] As this is in Fig. As shown in Figure 3, the shield connector A includes a connection module 10, which is connected to a front end portion of a shielded cable 60, and a housing 45. The shielded cable 60 is configured such that a pair of internal conductors 61, each surrounded by an insulating coating, are jointly enclosed by a shielding shell or sheath 62, which is formed from stranded wire, and the shielding shell 62 is enclosed by a sleeve 63. Front end portions of the pair of internal conductors 61 are positioned by a clamp or clip 64. A front end portion of the shielding shell or sheath 62 is folded backward and serves as a folded section 65, which is placed on the outer circumference of the sleeve 63. A hollow cylindrical sleeve or socket 66 serves as a reinforcing element.Reinforcing element mounted or arranged between the outer circumference of the shell 63 and the folded section 65 of the shielding shell 62.

[0021] The connection module 10 comprises a pair of left and right inner conductors 11, a dielectric 12 for receiving the pair of inner conductors 11, and an outer conductor 15 for surrounding the inner conductors 11 and the dielectric 12. The rear end sections of the pair of inner conductors 11 are connected to the pair of internal conductors 61. The dielectric 12 is configured by combining a receiving element 13 and a covering element 14 and has an overall rectangular parallelepiped shape. The pair of inner conductors 11 is received within the dielectric 12, sandwiched between the receiving element 13 and the covering element 14.

[0022] The outer conductor 15 is configured or constructed by assembling a body member 16, which is made of metal, and a connecting member 30, which is made of metal and is separate from the body member 16. The body member 16 is formed by bending and striking a metal sheet material, which has a predetermined shape, by means of a pressing process. As this is shown in Fig. As shown in Figure 2, the body member 16 includes a rectangular or right-angled tube section 17, a first covering section 18 which projects backward from the rear end of the right-angled tube section 17, and a locking or locking section 19 which extends backward from the rear end of the first covering section 18.

[0023] As this is in Fig. 1 and Fig. As shown in Figure 2, the right-angled pipe section 17 includes an upper plate section 20, a lower plate section 21, and a pair of left and right side plate sections 22. Both a left and right side edge of the upper plate section 20 and the upper end edges of the pair of side plate sections 22 are joined at a right angle, forming corner ridges extending in the forward-backward direction. Both the left and right side edges of the lower plate section 21 and the lower end edges of the pair of side plate sections 22 are also joined at a right angle, forming corner edges extending in the forward-backward direction. The locking section 19 is enclosed at the rear by a centrally located, laterally central, orprojecting central part of the rear end edge of the lower plate section 21.

[0024] Each of the upper plate section 20 and the lower plate section 21 of the right-angled tube section 17 is formed with a pair of bilaterally symmetrical restorable contact sections 23. The pair of elastic or restorable contact sections 23 is arranged while spaced apart from each other in the lateral direction of the upper plate section 20 and the lower plate section 21. One restorable contact section 23 is formed at a vertical central position of each of the two left and right side plate sections 22. The restorable contact sections 23 project outwards from the outer surfaces of the respective plate sections 20, 21, and 22. Six restorable contact sections 23 are arranged only in a region forward of a center point in the forward-backward direction of the right-angled tube section 17.

[0025] The restorable contact section 23 has a shape or form which is elongated or extended in the forward-backward direction parallel to an axis 24 (see Fig. 5) of the outer conductor 15 in total. Both the front and rear ends (in a longitudinal direction) of the restorable contact sections 23 are connected to the respective plate sections 20, 21, and 22 (which form bases). When viewed from a direction parallel to the outer surface of each plate section 20, 21, 22 and orthogonal to a longitudinal direction of the restorable contact section 23, the restorable contact section 23 has an arrow or zigzag shape. A curved portion corresponding to an upper part of the zigzag shape of the restorable contact section 23 serves as a contact point section, which is in contact with the inner circumferential surface of a matching outer conductor 68 (see Fig. 5) to be formed in the shape of a rectangular or right-angled tube.

[0026] The two left and right side plate sections 22, which form the rectangular tube section 17, are each provided with a pair of bilaterally symmetrical positioning projections 27. These projections are located behind the center in the forward-backward direction of the rectangular tube section 17. The first covering section 18 is connected to the entire width region of the rear end edge of the lower plate section 21 and the lower end regions of the rear end edges of the two left and right side plate sections 22, and has a curved shape that is concave on one side of an upper surface.The locking section 19 extends straight backwards parallel to the axis 24 of the outer conductor 15 from a laterally central part of the rear end edge of the first covering section 18.

[0027] As this is in Fig. 1 and Fig. As shown in Figure 2, the connecting member 30 comprises a box-shaped coupling section 31, which has an open lower surface, a second covering section 38, and a crimping section 39 in the form of an open drum. The coupling section 31 includes a base plate section 32 in the form of a flat plate, a pair of bilaterally symmetrical fixing elements 33 extending downwards from both left and right side edges of the base plate section 32, and a pair of bilaterally symmetrical stabilizers 34 extending downwards at a right angle from both left and right side edges of the base plate section 32. The base plate section 32 is formed with a rectangular locking hole 35. A locking projectionExtension 36, which projects outwards from the base plate section 32, is formed on a front end edge part of the opening edge or the opening edge of the locking hole 35.

[0028] The fixing or securing pieces 33 are connected to regions, with the exception of the front end portions, of the side edge portions of the base plate section 32. In a state prior to the joining member 30 being joined to the body member 16, the fixing pieces 33 are in the form of flat plates perpendicular to the base plate section 32. In a step of assembling the joining member 30 with the body member 16, extending end portions of the fixing pieces 33 are bent parallel to the base plate section 32. The stabilizers 34 are connected to the front end portions of the side edge portions of the base plate section 32. Positioning grooves 37 are formed between the rear end edges of the stabilizers 34 and the front end edges of the fixing pieces 33.

[0029] The second covering section 38 is connected to the entire width region of the rear end edge of the base plate section 32 and the upper end regions of the rear end edges of the two left and right fixing pieces 33. The second covering section 38 has a curved shape, which is concave on one side of a lower surface (the side facing the first covering section 18), unlike the first covering section 18. The crimping section 39 includes a base section 40, which is connected to the rear end edge of the second covering section 38, and crimping pieces 41, which project from both left and right side edges of the base section 40.

[0030] When the body member 16 and the connecting member 30 are joined, the positioning projections 27 and the positioning grooves 37 are fitted, the coupling section 31 is placed on a rear end portion of the rectangular tube section 17, the base plate section 32 is placed on the outer surface of the upper plate section 20, and both the left and right fixing pieces 33 are placed on the outer surfaces of the two left and right side plate sections 22. By fitting the positioning projections 27 and the positioning grooves 37, the body member 16 and the connecting member 30 are positioned in the forward-backward direction. Since the coupling section 31 is assembled behind the restoring contact sections 23, the base plate section 32 and the stabilizers 34 do not interact with the restoring contact sections 23.

[0031] The lower end parts of the two fixing pieces 33 are then bent and placed on the outer surface of the lower plate section 21. As shown in Fig. 2 and Fig. As shown in Figure 5, the lower end parts of the fixing pieces 33, which are placed on the outer surface of the lower plate section 21, project from the outer surface of the rectangular tube section 17 in a step-like manner as a pair of bilaterally symmetrical projecting sections or areas 42. The projecting sections 42 are arranged on a rear end part of the rectangular tube section 17 and are positioned behind the restorable contact sections 23. In the above manner, the body member 16 and the connecting member 30 are combined and integrated, thereby forming the outer conductor 15. A front end part of the rectangular tube section 17, where the restorable contact sections 23 are formed, projects forward from the front end of the coupling section 31 of the connecting member 30. A tubular shielding section 43 is also formed.is represented or formed by the first covering section 18 and the second covering section 38 behind the right-angled pipe section 17.

[0032] The dielectric 12 is guided through the two covering sections 18, 38 and received into the right-angled tube section 17 from behind the outer conductor 15. The inner conductors 11, which are connected to the internal conductors 61, are received in the dielectric 12. After the dielectric 12 is inserted into the right-angled tube section 17, the base section 40 of the crimping section 39 and the locking section 19 are placed on the outer circumference of the shielding layer 62 to radially sandwich the shielding layer 62, and the crimping pieces 41 are crimped onto the outer circumferences of the locking section 19 and the folded section 65. The extending end parts of the crimping pieces 41 are locked to the locking section 19 in a circumferential direction. If the crimping section 39 is conductively crimped onto the front end part of the shielding layer 62, thenThe connection module 10 is connected to the front end part of the shielded cable 60.

[0033] When the connection module 10 and the shielded cable 60 are connected, the entire inner conductors 11 are shielded by being surrounded by the right-angled tube section 17 of the outer conductor 15. Regions of the inner conductors 61 between the front end of the shielding layer 62 and the rear end of the right-angled tube section 17 are shielded by being surrounded by the tubular shielding section 43. Since it is continuous around its entire circumference by having the four plate sections 20, 21, and 22, the right-angled tube section 17 exhibits high shielding performance. Since both the left and right end parts of the first covering section 18 and both the left and right end parts of the second covering section 38 are in contact without any gap, the tubular shielding section 43 also exhibits high shielding performance. Therefore, electromagnetic noise, which would otherwise leak into a conductive or shielded conductor, is effectively blocked.a conductive path is created or generated, which consists of the internal conductors 61 and the inner conductors 11, not to the outside of the outer conductor 15 between the front end of the shielding layer 62 to the front end of the outer conductor 15.

[0034] The housing 45 is a single component made from a synthetic resin or plastic. As this is shown in Fig. As shown in Figure 5, a module receiving chamber 46, which extends through the housing 45 in the forward-backward direction, is formed inside the housing 45. The connection module 10 is inserted into the module receiving chamber 46 from behind the housing 45. The module receiving chamber 46 includes a connecting chamber 47, which is open in the front surface of the housing 45 and has a rectangular or right-angled cross-section; a locking chamber 48, which is connected behind the connecting chamber 47 and has a rectangular or right-angled cross-section; and a rear chamber 49, which is connected to the rear end of the locking chamber 48 and is open in the rear end surface of the housing 45.

[0035] When the connection module 10 is inserted into the module receiving chamber 46, a portion of the outer conductor 15 in front of the front end of the connecting link 30, i.e., a portion where the right-angled tube section 17 is exposed, is received in the connection space 47. A fitting space for receiving the matching outer conductor 68 is provided between the outer circumferential surface of the right-angled tube section 17 and the inner circumferential surface of the connection space 47. The tubular shielding section 43 and the crimping section 39 of the outer conductor 15 are received in the rear space 49. The coupling section 31 of the connecting link 30 is received in the locking space 48.

[0036] The locking chamber 48 is defined by an upper wall surface, a lower wall surface, and a pair of left and right side wall surfaces. A locking lance 52, projecting forward, is formed on the upper wall surface. The locking lance 52 can be elastically deformed in the vertical direction. When the connection module 10 is inserted into the module receiving chamber 46, the upper surface of the base section 40 of the coupling section 31 faces directly toward the upper wall surface of the locking chamber 48, and the locking lance 52 is locked from behind at the locking hole 35 and the locking projection 36. By locking the locking lance 52, the connection module 10 is retained and held in the housing 45.

[0037] When the connection module 10 is inserted into the module receiving chamber 46, the lower surfaces of the projecting sections 42, which are placed on the upper surface of the right-angled pipe section 17, are positioned on the lower wall surface of the locking chamber 48. As shown in Fig. 4 and Fig. As shown in Figure 5, a region of the lower surface of the rectangular pipe section 17 in front of the projecting sections 42 is directed towards the lower wall surface across a gap or distance S of a dimension equal to a projecting dimension of the projecting sections 42. The lower wall surface of the locking space 48 is a surface which is directed or faced towards the lower surface of the rectangular pipe section 17, where the projecting sections 42 are arranged, from the outer surface of the outer conductor 15, and is defined as an facing inner surface 54 in this embodiment.

[0038] Since the gap S between the facing inner surface 54 and the lower surface of the outer conductor 15 is located in a region of the facing inner surface 54 in front of the projecting sections 42, there is concern that the connection module 10 might vibrate or rattle like a seesaw in the module receiving chamber 46, with the front ends of the projecting sections 42 acting as a pivot or lever point. As a countermeasure, a pair of left and right sections 55, which eliminate play or backward movement, are formed on the facing inner surface 54. The play-eliminating sections 55 are elongated in the forward-backward direction and in the form of ribs projecting from the facing inner surface 54.The play-eliminating sections 55 are arranged and positioned on a front end portion of the facing inner surface 54 to be directed towards the lower surface of the right-angled pipe section 17 in front of the projecting sections 42. The contact of the upper ends of the play-eliminating sections 55 with the lower surface of the right-angled pipe section 17 suppresses or prevents the connecting module 10 from rattling or vibrating like a rocking motion.

[0039] As this is in Fig. 4 and Fig. As shown in Figure 6, the backlash-eliminating section 55 has a semicircular shape in a front view of the housing 45. That is, the width of the backlash-eliminating section 55 is greatest at a lower end, which is connected to the facing inner surface 54, and decreases progressively in a projecting direction (towards an upper side). The pair of backlash-eliminating sections 55 is arranged bilaterally symmetrically in the width directions of the module receiving chamber 46 and the connection module 10.

[0040] As this is in Fig. As shown in Figure 4, the pair of backlash-eliminating sections 55 is arranged at positions different from the pair of restorable contact sections 23 formed in the lower plate section 21 of the connection module 10, as seen from the front view. That is, the pair of backlash-eliminating sections 55 is positioned between the pair of restorable contact sections. During the insertion of the connection module 10 into the module receiving chamber 46, the restorable contact sections 23 pass laterally to the backlash-eliminating sections 55 without colliding with them, and reach predetermined positions (connection space 47) in front of the backlash-eliminating sections 55.

[0041] As this is in Fig.As shown in Figure 6, the pair of play-eliminating sections 55 is arranged to be oriented towards the locking lance 52 in a restorable deformation direction (vertical direction). In other words, the locking lance 52 and the pair of play-eliminating sections 55 are in such a positional relationship that they vertically sandwich the connection module 10. In the lateral direction, the pair of play-eliminating sections 55 is formed in a section of the locking lance 52. The connection module 10, which is inserted into the module receiving chamber 46, is pressed downwards (towards the facing inner surface 54) by the locking lance 52 in a restorable manner.This pressing action keeps the lower surface of the right-angled tube section 17 in contact with the upper ends of the pair of clearance-eliminating sections 55.

[0042] The shield connector A of this embodiment is provided with the housing 45, which includes the module receiving chamber 46, and the connection module 10, which is to be inserted into the module receiving chamber 46 from behind the housing 45. In the connection module 10, the inner conductors 11 are surrounded by the dielectric 12, and the dielectric 12 is surrounded by the outer conductor 15. The outer conductor 15 includes the projecting sections 42, which project from the positions behind the front end of the outer conductor 15 onto the outer surface of the outer conductor 15. The inner wall surface, which forms the module receiving chamber 46, has the facing inner surface 54. The facing inner surface 54 is directed towards the outer surface of the outer conductor 15 (lower surface of the right-angled tube section 17), on which the projecting sections 42 are formed.The facing inner surface 54 is formed with the projecting sections 55, which eliminate play or counter-movement. When the connection module 10 is inserted into the module receiving chamber 46, the projecting sections 42 are arranged behind the play-eliminating sections 55.

[0043] When the connection module 10 is inserted into the module receiving chamber 46, the gap S is formed, due to the presence of the projecting sections 42, between the region in front of the projecting sections 42, the outer surface of the outer conductor 15, and the facing inner surface 54 of the module receiving chamber 46. However, because the projecting, clearance-eliminating sections 55, which are formed in the module receiving chamber 46, are present in this gap S, the connection module 10 is not inclined with the projecting sections 42 as a pivot or lever point. In this way, vibration or rattling of the connection module 10 in the housing 45 can be prevented.

[0044] Leading or guide surfaces 56, which are inclined relative to the insertion direction of the connection module 10 into the module receiving chamber 46, are formed on the rear end portions of the clearance-eliminating sections 55. During the insertion process of the connection module 10, the front end of the connection module 10 slides into contact with the leading surfaces 56 without striking or colliding with the clearance-eliminating sections 55. In this way, the connection module 10 can be inserted into the module receiving chamber 46 without any problems. The pair of clearance-eliminating sections 55 are arranged in a bilaterally symmetrical positional relationship, while being spaced apart in the lateral direction of the connection module 10. The contact of the connection module 10 with the pair of clearance-eliminating sections 55 prevents any inclination of the connection module 10 in the lateral direction.

[0045] In a cross-section of the clearance-eliminating section 55, which is cut perpendicular to the insertion direction of the connection module 10, the clearance-eliminating section 55 has a semicircular shape, which is narrowed in the projecting direction from the facing inner surface 54. By forming the clearance-eliminating section 55 into a semicircular cross-sectional shape, sliding resistance between the connection module 10 and the clearance-eliminating section 55 during the insertion process of the connection module 10 can be reduced, while ensuring the strength of the clearance-eliminating section 55.

[0046] The module receiving chamber 46 is equipped with a resiliently deformable locking lance 52 for retaining the connection module 10, which is inserted into the module receiving chamber 46. The locking lance 52 is positioned opposite the facing inner surface 54 and extends transversely across the connection module 10, and can exert a restoring force on the connection module 10. Since the connection module 10 is held in contact with the clearance-eliminating sections 55 by a restoring pressing force of the locking lance 52, vibration or wobble of the connection module 10 can be more effectively prevented.

[0047] The outer surface of the outer conductor 15 is formed with restorable contact sections 23, which are configured to make restorable contact with the matching element (the matched outer conductor 68) that is to be connected to the outer conductor 15. The clearance-eliminating sections 55 are arranged at positions different from the restorable contact sections 23 in the width direction of the connection module 10. Thus, during the insertion of the connection module 10 into the module receiving chamber 46, the restorable contact sections 23 do not interact with the clearance-eliminating sections 55. In this way, an increase in insertion resistance due to restorable deformation of the restorable contact sections 23, which would be caused by contact with the clearance-eliminating sections 55, can be avoided.

[0048] The outer conductor 15 is configured or constructed by combining the body member 16 to surround the dielectric 12 and the connecting member 30, which includes the crimping section 39 that is to be connected to the shielding layer 62 of the shielded cable 60. The fixing or securing pieces 33, which are formed on the connecting member 30, are bent and placed on the outer surface of the body member 16, thereby forming the projecting sections 42. According to this configuration, the simplification of the shape or form of each member 16, 30, the simplification of a construction step of each member 16, 30, and the like, can be achieved by dividing the outer conductor 15 into two components comprising the body member 16 and the connecting member 30.

[0049] The body section 16 includes the rectangular or right-angled tube section 17 for surrounding the dielectric 12 and the first covering section 18, which extends rearward from the right-angled tube section 17. The connecting link 30 includes the second covering section 38, which couples the fixing pieces 33 and the crimping section 39. When the body section 16 and the connecting link 30 are joined, the tubular shielding section 43 is formed by the first and second covering sections 18 and 38. The tubular shielding section 43 surrounds the regions of the internal conductors 61 of the shielded cable 60 between the shielding layer 62 and the right-angled tube section 17. According to this configuration, leakage or the escape of electromagnetic noise between the shielding layer 62 and the right-angled tube section 17 can be prevented. [Other embodiments]

[0050] The present invention is not limited to the embodiment described and illustrated above and is represented by the claims. The present invention is intended to include all modifications within the scope of the claims and in the meaning and scope of equivalents, and also includes the following embodiments.

[0051] Although the section eliminating play or counter-movement has a semicircular cross-sectional shape in the above embodiment, the section eliminating play can have a trapezoidal cross-sectional shape.

[0052] Although the cross-sectional shape or form of the play-eliminating section is narrowed in the projecting direction in the above embodiment, the cross-sectional shape of the play-eliminating section can have a constant width from a base end to a projecting end.

[0053] Although the locking lance presses or pushes the connection module against the play-eliminating sections in the above embodiment, the locking lance does not necessarily have to press the connection module against the play-eliminating sections.

[0054] Although the pair of play-eliminating sections is arranged in a symmetrical positional relationship while being spaced apart in the width direction of the connection module in the embodiment above, the pair of play-eliminating sections can be arranged in an asymmetrical positional relationship in the width direction.

[0055] Although the pair of game-eliminating sections is provided in the above embodiment, the number of game-eliminating sections can be one, three, or more.

[0056] Although the play-eliminating sections are arranged at positions different from the restorable contact sections in the width direction of the connection module in the above embodiment, the play-eliminating sections can be arranged at positions that interact with or meet the restorable contact sections in the width direction of the connection module.

[0057] Although the outer conductor consists of two components, which in the above embodiment include the body part and the connecting part, the outer conductor can be a single component.
