[Bibliography][Patent Literature] Patent literature 1: Japanese, unexamined patent publication no. 2013-229255 Patent literature 2: Japanese, unexamined patent publication no. 2012-18898 [Summary of the invention][Problem that the invention seeks to solve]
[0003] In the case described in patent literature 1, the sheathing of the shielded cable is fixed by the drum section when the dielectric is inserted into the shielding shell. When the drum section is crimped, the dielectric can be displaced relative to the shielding shell.
[0004] Accordingly, the present disclosure aims to provide a shielding connector capable of preventing the displacement of a dielectric. [Means to solve the problem]
[0005] The present disclosure relates to a shield connector comprising an inner conductor, a dielectric for receiving the inner conductor, and an outer conductor for surrounding the dielectric, wherein the dielectric includes a stop section for stopping or halting a movement of the dielectric along a wall surface of the outer conductor by contacting or bumping against the outer conductor. [Effect of the invention]
[0006] According to the present disclosure, it is possible to provide a shielding connector which is capable of preventing a displacement or shifting of a dielectric.

[Embodiments of the invention][Description of embodiments of the present disclosure]
[0007] First, embodiments of the present disclosure are listed and described.
[0008] (1) A shielding connector of the present disclosure is provided with an inner conductor, a dielectric for receiving the inner conductor, and an outer conductor for surrounding the dielectric, the dielectric including a stop section for stopping or halting movement of the dielectric along a wall surface of the outer conductor by contacting or abutting the outer conductor. For example, if the outer conductor is crimped, movement of the dielectric along the wall surface of the outer conductor can be stopped or halted by contacting or abutting the stop section on the outer conductor. In this way, according to the above configuration, displacement or shifting of the dielectric relative to the outer conductor can be prevented.
[0009] (2) Preferably, the dielectric includes a support element for positioning the inner conductor and a cover element for attaching to the support element, and the stop section is provided on the support element. Thus, the inner conductor is positioned by the support element, and the relative position of the inner conductor with respect to the outer conductor can be determined via the stop section of the support element. In this way, a constant distance between the inner and outer conductors can be maintained, and the impedance can be precisely adjusted.
[0010] (3) The stop section can be shaped to project into a space in the outer conductor. Accordingly, an air layer representing or forming the space in the outer conductor is replaced by a resin or plastic, which forms the stop section in a projecting region of the stop section in the outer conductor. As a result, the stop section can exhibit an impedance adjustment function.
[0011] (4) The outer conductor includes a tubular body section of the outer conductor, which is open at the front and rear. The body section of the outer conductor includes a stop-receiving section at a rear end, wherein the stop section rests against the stop-receiving section. A rear portion, comprising the rear end, of the body section of the outer conductor is thicker than a front portion, comprising a front end. Forward movement (displacement) of the dielectric relative to the outer conductor can be prevented by the stop section resting against the stop-receiving section. In particular, since the stop-receiving section is provided in the thick rear portion of the body section of the outer conductor, concerns regarding deformation or displacement can be avoided.Deformation during an encounter with the impact section is reduced. On the other hand, since it is thinner than the rear part, the front part of the body section of the outer conductor, for example, has a spring structure to deflect and deform. [Details of an embodiment of the present disclosure]
[0012] A specific example of a shielding connector of the present disclosure is described below with reference to the drawings. It should be noted that the present invention is not limited to these illustrations and is intended to be represented by claims, including all modifications in the scope of claims and in the meaning and scope of equivalents. <Ausführungsform>
[0013] A shielding connector of one embodiment includes, as described in Fig. Figure 1 shows a housing 10, a first outer conductor 11, a second outer conductor 12, a supporting element 13, a cover element 14, a pair of inner conductors 15, a terminal 16, and a sleeve 17. The first and second outer conductors 11 and 12 are assembled to form an outer conductor 18. The supporting element 13 and the cover element 14 are assembled to form a dielectric 19. With the exception of the housing 10, part of the shield connector is configured as a connection module 20 (see Figure 1). Fig. 2) It should be noted that in the following description, a slanted lower left side of Fig. 1 is defined as a front side or front pertaining to a forward-backward direction, and a vertical direction is based on a vertical direction which is in Fig. 1 is shown.
[0014] The connection module 20 is connected to an end part of a shielded cable 90. As shown in Fig. As shown in Figure 1, the shielded cable 90 comprises a pair of coated or sheathed wires 93, in which internal conductors 91 are surrounded by insulating coatings, a shielding layer 94, such as a braided wire, which together surrounds the pair of coated wires 93, and a sheath 95, which surrounds the shielding layer 94. A front end portion of the shielding layer 94 is folded backward and placed on the outer circumference of the sheath 95 to form a folded section 96.
[0015] The sleeve 17 is made of metal, has a hollow cylindrical shape, and is mounted between the outer circumference of the sheath 95 and the folded section 96 of the shielding layer 94. The clamp 16 is made of metal and is in the form of a plate and holds the front end parts of the pair of coated wires 93 in a positioned position.
[0016] The pair of inner conductors 15 is connected to the pair of internal conductors 91. Each inner conductor 15 is positioned by the supporting member 13 and received in the dielectric 19, while being enclosed or clamped between the supporting member 13 and the cover member 14 (see Fig. 2).
[0017] The dielectric 19 (supporting element 13 and cover element 14) is made of a synthetic resin.
[0018] The supporting element 13 represents an upper part of the dielectric 19. As shown in Fig. As shown in Figure 5, the supporting member 13 comprises a supporting body section 21 in the form of a rectangular or right-angled plate extending along the forward-backward direction and a lateral direction (broadness direction), an anterior wall section 22 projecting downward from the supporting body section 21 on a front face of the supporting body section 21 and having a rectangular or right-angled outer shape when viewed from the front, and a pair of left and right side wall sections 23 projecting downward from the supporting body section 21 on each of its left and right ends. The respective side wall sections 23 are subdivided on their front and rear sides by cut or truncated sections 24. The pair of anterior side wall sections 23 isis coupled to a left and right end of the front wall section 22. The respective cut or truncated sections 24 are open in the upper surface of the supporting body section 21 over the left and right ends of the supporting body section 21. The supporting body section 21 includes a pair of left and right locking projections 25 on the opening end surfaces of the respective cut or truncated sections 24. Each locking projection 25 extends into each cut section 24.
[0019] The front wall section 22 includes a pair of left and right insertion holes 26. When the shield connector is connected to a matching connector (not illustrated), a pair of matching terminals, which are mounted in the matching connector, are inserted through the pair of insertion holes 26. Each matching terminal is flat-pin or pin-type and is connected to each inner conductor 15. The front wall section 22 includes a pair of upper and lower recesses 27 in the form of cutouts at both the upper and lower ends of a front surface and at positions between the respective insertion holes 26 in the lateral direction.
[0020] As this is in Fig. As shown in Figure 6, the supporting body section 21 includes a rib-like partition 28, which extends in the forward-backward direction in a laterally central part of a lower surface. The front end of the partition 28 is coupled to a portion of the rear surface of the front wall section 22 between the respective insertion holes 26. The partition 28 is divided into front and rear sections by an opening 29, which passes through the supporting body section 21 at a position near the front wall section 22. An impedance adjustment element (not illustrated) may be inserted into the opening 29 between the front and rear sections of the partition 28.
[0021] The supporting member 13 includes a pair of connection-receiving sections 31 on both the left and right sides of the partition 28. The pair of connection-receiving sections 31 is defined as recesses by the front wall section 22, the partition 28, and the pairs of side wall sections 23. The pair of inner conductors 15 is received into the pair of connection-receiving sections 31. The pair of front side wall sections 23 includes a pair of locking sections 32 at positions near their lower ends. Each locking section 32 is in the form of a projection and extends into each connection-receiving section 31. Each inner conductor 15 isis inserted from below into the respective section 31 receiving a connection and positioned in the forward-backward direction with respect to the supporting member 13 by fitting the locking section 32 into a locking-receiving section or locking-receiving section 33 of a box-shaped part, as shown in . Fig. 2 is shown.
[0022] The supporting element 13 includes a stop or stop section 34. The stop section 34 is in the form of a rib that projects upward from a rear end portion of the upper surface of the supporting body section 21 and extends laterally. The stop section 34 is located behind the pair of rear side wall sections 23. In short, the stop section 34 is located at the furthest rear end of the dielectric 19.
[0023] As this is in Fig. As shown in Figure 5, the stop section 34 has a rectangular or right-angled cross-sectional shape and is formed to have a constant projecting dimension (vertical dimension) in the lateral direction except at the left and right end sections. The left and right end sections of the stop section 34 are located near the pair of rear side wall sections 23. The left and right end sections of the stop section 34 have a left and right corner truncated and a pair of slopes 35 inclined downwards towards both lateral sides. The front surface of the stop section 34 is a vertical surface extending along both the vertical and lateral directions. The front surface of the stop section 34 can abut or be connected to a stop-receiving section 53.to strike, which will be described later (see . Fig. 2).
[0024] The cover element 14 forms a lower part of the dielectric 19. As shown in Fig. As shown in Figure 7, the cover element 14 comprises a cover body section 36 in the form of a rectangular or right-angled plate and a pair of locking pieces 37, which project upwards from a left and right end part of the cover body section 36. Each locking piece 37 is in the form of a gate-shaped frame and includes a locking hole 38 inside.
[0025] In the process of assembling the cover member 14 with the supporting member 13, the respective locking pieces 37 engage with the respective locking projections or extensions 25 and are deflected and deformed laterally away from each other. Subsequently, the respective locking pieces 37 are returned to their original position and enter the corresponding cut sections 24, and the respective locking projections 25 are fitted into the respective locking holes 38 (see figure). Fig. 4) When the cover member 14 is assembled with the supporting member 13, the cover body section 36 closes openings in the lower surfaces of the pair of connection-receiving sections 31. The cover body section 36 includes a pair of left and right pressing sections 39 on an upper surface. The respective pressing sections 39 are in the form of flat bases and clamp and hold the respective inner conductors 15 between the supporting body section 21 and the pressing sections 39.
[0026] The outer conductor 18 (first and second outer conductor 11, 12) is made of a metal plate material and surrounds the inner conductors 15 and the dielectric 19.
[0027] As this is in Fig. As shown in Figure 1, the second outer conductor 12 includes a covering section 41 in the form of a box with an open lower surface and a crimping section 42 in the form of an open drum, which projects rearward from the rear end of the covering section 41. The covering section 41 includes a locking projection 43, which projects from a front end portion of an upper surface. The locking projection 43 is locked onto a locking lance 44 of the housing 10 (see Figure 1). Fig. 2) The covering section 41 includes a pair of retaining pieces 45, which project downwards from both the left and right sides. The crimping section 42 includes a plurality of crimping pieces 46, which project downwards from both the left and right sides.
[0028] As this is in Fig. As shown in Figure 8, the first outer conductor 11 comprises a body section 47 of the outer conductor, or outer conductor body section, in the form of a rectangular or right-angled tube, and a projecting section 49, which projects backward from the rear end of a lower plate section 48 of the body section 47 of the outer conductor, which will be described later. The body section 47 of the outer conductor comprises an upper plate section 51, the lower plate section 48, which is arranged below the upper plate section 51, and a pair of left and right side plate sections 52, which couple or connect a left and right end of the upper plate section 51 and a left and right end of the lower plate section 48. The rear end of the upper plate section 51 is arranged linearly along the lateral direction.The rear end of this upper plate section 51 is configured or constructed as the stop-receiving section 53, on which the stop section 34 rests or abuts (see . Fig. 2).
[0029] As this is in Fig. As shown in Figure 8, the upper plate section 51 and the lower plate section 48 include a pair of upper and lower projecting pieces 54, which are bent inwards to be directed towards each other in laterally central parts of their front ends. Each projecting piece 54 is in the form of a rectangular plate and can be fitted into the recess 27 (see Figure 8). Fig. 2) Each of the upper plate section 51 and the lower plate section 48 includes a pair of left and right restorable sections 55. Each of the pair of left and right side plate sections 52 includes a restorable section 55. Each restorable section 55 is arranged between slots 56, which extend parallel to the forward-backward direction in each plate section 48, 51, 52. Furthermore, each restorable section 55 is bent into an arrow or zigzag shape, which projects outward from the body section 47 of the outer conductor. Each restorable section 55 is deflectable and deformable at both its front and rear ends, acting as pivot or lever points.
[0030] A step 57 in an in-out direction (radial direction) is formed over the entire circumference on the inner surface of the body section 47 of the outer conductor. In the body section 47 of the outer conductor, a front part 58, which is located on a front side, is thinner than a rear part 59, which is located on the back side, both from the front and rear sides of the step 57. As shown in Fig. As shown in Figure 2, the inner surface of the front part 58 is positioned further outwards than that of the rear part 59 over the step 57. On the other hand, the outer surface of the front part 58 is flush and continuous with that of the rear part 59.
[0031] The front part 58 is configured or constructed in a region extending from the front end of the body section 47 of the outer conductor to the step 57. Each restorable section 55 is contained within the front part 58. By making the front part 58 thinner than the rear part 59, each restorable section 55 is gently deflected. The rear part 59, on the other hand, is constructed in a region extending from the step 57 to the rear end of the body section 47 of the outer conductor. The stop-receiving section 53 is contained within the rear part 59. By making the rear part 59 thicker than the front part 58, the durability of the stop-receiving section 53 can be improved.
[0032] Next, the manufacturing process and functions of the connection module 20 will be described.
[0033] First, each inner conductor 15 is inserted into each terminal receiving section 31, and the cover member 14 is locked and secured to the supporting member 13 by locking each locking piece 37 and each locking projection 25, thereby configuring the dielectric 19. Each inner conductor 15 is positioned by the locking section 32 of the supporting member 13 and enclosed and held between the supporting member 13 and the cover member 14.
[0034] The dielectric 19 is then inserted into the body section 47 of the outer conductor from the rear. Each protruding portion 54 of the body section 47 of the outer conductor is fitted into each recess 27 of the front wall section 22, and the front surface of the stop section 34 rests against the stop-receiving section 53 of the body section 47 of the outer conductor, thus stopping the insertion process of the dielectric 19. When the dielectric 19 is properly inserted into the body section 47 of the outer conductor, the folded section 96 of the shielding layer 94 is positioned on the protruding section 49. A gap is formed between the outer surface of the dielectric 19 and the inner surface of the front part 58 (see Fig. 2) Each resilient section 55 can be deflected and deformed in the direction of the gap.
[0035] The covering section 41 is subsequently arranged to be placed from above onto a rear portion of the body section 47 of the outer conductor. In this state, the respective retaining pieces 45 are bent inwards and crimped to surround the lower plate section 48, and the crimping section 42 is crimped onto the outer circumference of the folded section 96. By locking the tips of the respective crimping pieces 46 to the projecting section 49, the outer conductor 18 and the shielding layer 94 are electrically connected.
[0036] Here, the stop section 34 is arranged in front of the folded section 96 and below a boundary region between the covering section 41 and the crimping section 42 in a space in the second outer conductor 12 (see Fig. 2) The upper surface of the stop section 34 is in contact with or near the inner surface of the second outer conductor 12. In a crimping step of the crimping section 42 and the like, both the left and right end portions of the upper wall of the second outer conductor 12 are deformed to be curved downwards. As this is shown in Fig. As shown in section 3, the deformed parts are (parts which are damaged by A of the Fig. (3 are shown) the upper wall of the second outer conductor 12 immediately adjoining both the left and right end parts of the stop section 34, but arranged away from the respective inclinations 35. In other words, the respective inclinations 35 of the stop section 34 are shaped to be withdrawn away from the deformed parts of the upper wall of the second outer conductor 12.
[0037] Furthermore, in the crimping step of the crimping section 42 and the like, the first outer conductor 11 and the dielectric 19 receive a crimping force from the side of the second outer conductor 12 and a displacement force for moving the dielectric 19 forward with respect to the first outer conductor 11 is applied to the dielectric 19.
[0038] However, in this embodiment, even when the displacement force is applied to the dielectric 19, the front surface of the stop section 34 is stopped or halted in contact with the stop-receiving section 53 of the body section 47 of the outer conductor, or a state is maintained where the front surface of the stop section 34 is stopped in contact with the stop-receiving section 53. In this way, forward movement of the dielectric 19 relative to the first outer conductor 11 is prevented. As a result, the relative positions of the outer conductor 18 and the dielectric 19 are kept constant, and consequently, a distance between each inner conductor 15 and the outer conductor 18 is also kept constant in order to suppress any change in impedance.
[0039] It should be noted that when the above displacement force is applied to the dielectric 19, the rear surface of each depression 27 also abuts or strikes each projecting section 54, thereby fulfilling the function of restricting movement of the dielectric 19 with respect to the first outer conductor 11. Naturally, since the front part 58 is thin and the projecting extent of each projecting section 54 is small, the function of limiting displacement of the dielectric 19 by the rear surface of each depression 27 abutting each projecting section 54 is only supported by the stop section 34.
[0040] The connection module 20, which is completed in the manner described above, is inserted into the housing 10 and held in place in the housing 10 by the locking projection 43, which is locked by the locking lance 44 (see Fig. 2) The housing 10 is then connected to the not illustrated tuned or matching connector, a not illustrated tubular tuned outer conductor surrounds the outer circumference of the front part 58 of the body section 47 of the outer conductor, and each restorable section 55 electrically contacts the inner circumference of the tuned outer conductor.
[0041] As described above, according to this embodiment, when the second outer conductor 12 is crimped onto the first outer conductor 11, the stop section 34 rests against the outer conductor 18, thereby preventing the dielectric 19 from moving forward along the inner surface (wall surface) of the body section 47 of the outer conductor. In this way, displacement of the dielectric 19 relative to the first outer conductor 11, and thus of the outer conductor 18, is prevented.
[0042] Furthermore, since the stop section 34 is provided on the supporting member or support member 13 and the supporting member 13 includes the locking sections 32 for positioning the respective inner conductor 15, relative positions of the respective inner conductor 15 and the outer conductor 18 are also determined and an impedance can be precisely set.
[0043] Furthermore, since the stop section 34 is shaped to project into the space in the outer conductor 18, the space in the outer conductor 18 can be filled by a projecting region of the stop section 34. In other words, an air layer, which constitutes the space in the outer conductor 18, is replaced by a resin layer, which constitutes the stop section 34, in the projecting region of the stop section 34 in the outer conductor 18. In this way, the stop section 34 can exhibit an impedance-setting function.
[0044] Furthermore, since the rear part 59, which includes the stop-receiving section 53, is thicker than the front part 58 of the body section 47 of the outer conductor, concerns regarding deformation or distortion due to contact with the strike section 34 can be reduced. On the other hand, since each restorable section 55 is provided in the front part 58, which is thinner than the rear part 59, each restorable section 55 can be gently deflected and deformed. [Other embodiments]
