Description

[Technical field]

[0001] One technique revealed in this description relates to a connector that is to be connected to one end of a shielded cable. [State of the art]

[0002] US 2011 / 0111628A1 describes a cable arrangement comprising an insulating housing having a recess formed on its rear side, a plurality of contacts arranged in the insulating housing, a printed circuit board having a front section that is received in the recess and electrically connected to the plurality of contacts, the printed circuit board having a first printed circuit board and a second printed circuit board stacked back-to-back, a shielding element enclosing the housing and the printed circuit board, and a cable with a plurality of conductive wires extending into the shielding element and electrically connected to a rear section of the printed circuit board.

[0003] US 2015 / 0044906A1 describes an HDMI cable, an HDMI connector, and an HDMI interface for a high-definition video / audio device. The HDMI interface comprises the HDMI connector and the HDMI cable. The HDMI connector includes a connection terminal with a cable end arranged in parallel within a main body. The HDMI cable contains at least one connection unit consisting of a plurality of parallel metal wires. An insulating unit covers an outer surface of a face of the connection unit such that the metal wires are parallel and insulated from one another.

[0004] US 9,437,976 B2 describes an electrical connector comprising an insulating housing defining a number of receiving spaces; a number of contacts attached to the insulating housing for transmitting a high-speed signal, each contact comprising an engagement section, a mounting section received in one of the receiving spaces, and a connecting section linking the engagement section and the mounting section, with a gap formed between each mounting section and the corresponding receiving space; and a number of insulating elements inserted into the receiving spaces to fill the gaps in order to adjust the impedance of the contacts.

[0005] US 2009 / 0246998A1 describes an electrical connector comprising a first metal part defining a sheathed engagement interface with a top surface and a first rear section; a second metal part housed within the first metal part and having a second rear section which, together with the first rear section, defines a receiving space; an insulated housing together with terminals received in the sheathed engagement interface; and at least one locking element formed integrally with the first or second metal part and extending into the concealed engagement surface, and a hook formed at a free end of the locking element and extending through the top surface of the concealed engagement surface and retracting into the concealed engagement surface when an external force is applied.

[0006] JP 2012-18898 A discloses a connector comprising a base section made of metal and open at the top, and a shell cover section, also made of metal, which is assembled with the base section from above. Locking holes extend through the side walls of the base section. The shell cover section is cut and raised at positions corresponding to the locking holes to provide locking projections that engage with the locking holes. The base section and the shell cover section are integrally assembled by a restorable locking action of the locking projections against the edge portions of the locking holes. [Summary of the invention][Problem that the invention seeks to solve]

[0007] However, according to the configuration described above, gaps or spaces are formed between the locking holes and the locking protrusions when the base section and the shell cover section are integrally or integrally assembled. Furthermore, the base section is designed with multiple locking holes to lock another member or element. Therefore, there are concerns that noise may enter from the outside or escape to the outside through the aforementioned gaps and locking holes when the base section and the shell cover section are integrally assembled.

[0008] The technology revealed in this description was developed based on the above situation and aims to provide a technology relating to a connector with improved shielding performance. [Means to solve the problem]

[0009] The underlying technical problem is solved by a connector according to claim 1 and a connector structure according to claim 3. Further embodiments are defined in claims 2 and 4.

[0010] According to the configurations above, the opening formed in the first outer conductor is closed off by the surrounding section of the second outer conductor. Since the ingress of noise from outside and the leakage or escape of noise to the outside through the first and second outer conductors can be suppressed in this way, the shielding performance of the connector can be improved.

[0011] The inner conductor is surrounded by an insulating dielectric, and the tubular section of the first outer conductor is formed with a locking element. The locking element can project inwards from the tubular section to hold the dielectric, with the through-hole being located near the locking element.

[0012] According to the configuration above, the dielectric in the tubular section can be locked in place by the locking element. Furthermore, since the through-hole formed near the locking element is closed by the surrounding section, the shielding performance of the connector can be improved. [Effect of the invention]

[0013] According to the technique revealed in this description, shielding performance can be improved.

[Embodiments of the invention]<Erste Ausführungsform>

[0014] A first embodiment in which the technology disclosed in this description is applied to a socket connector structure 10 (example of a connector structure) is described with reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Fig. 10, Fig. 11, Fig. 12, Fig. 13, Fig. 14, Fig. 15 to Fig. 16. In the socket connector structure 10 according to this embodiment, a receiving socket connector 12 (example of a connector) is connected to one end of a shielded cable 11. In the following description, a Z direction, a Y direction, and an X direction are each referred to as an upward direction, a forward direction, and a leftward direction, respectively. Only some of a plurality of links or elements may or will be designated by a reference numeral, and the other links may or need not be designated by a reference numeral. [Shielded cable 11]

[0015] The shielded cable 11 is configured such that the outer circumferences of a plurality of (two in this embodiment) sheathed or coated wires 13 are surrounded by a stranded wire 14 (example of a shielding section) made of thin metal wires, and the outer circumference of the stranded wire 14 is surrounded by a sheath 15 made of an insulating material. Each sheathed wire 13 includes a core 16 and an insulating sheath 17 surrounding the outer circumference of the core 16. Any metal, such as copper, a copper alloy, aluminum, or an aluminum alloy, can be selected as the metal forming the core 16 according to the requirements. The core 16 can be formed by a metal strand or by a stranded orThe wire is formed by twisting together a plurality of metal strands or strands. The insulating coatings 17 and the sheathing or covering 15 are made of an insulating synthetic resin.

[0016] A one-end processing step, such as stripping, is applied to one end of the shielded cable 11 to expose one end of each of the cores 16, insulation sheaths 17 and stranded wire 14. [Buckle connector 12]

[0017] The receiving or socket connector 12 includes receiving or socket terminals 18 (example of an inner conductor), an insulating dielectric 19 for surrounding the outer circumferences of the socket terminals 18, and an outer conductor 20 for surrounding the outer circumference of the dielectric 19. The outer conductor 20 includes a first outer conductor 33 and a second outer conductor 34, which is electrically connected to the first outer conductor 33. [18 socket connections]

[0018] The socket terminal 18 is formed by pressing a metal sheet material into a predetermined shape. Any metal, such as copper, a copper alloy, aluminum, or an aluminum alloy, can be selected as the metal forming the socket terminal 18 according to the requirements. The socket terminal 18 is connected to the end of each sheathed or coated wire 13. The socket terminal 18 comprises an insulation drum 21 to be crimped around the outer circumference of the insulating coating 17 of the sheathed wire 13, a wire drum 22 to be connected and crimped in front of the insulation drum 21 to wrap around the outer circumference of the core 16, and a connecting tube section 23 to be connected in front of the wire drum 22, wherein a matching (not illustrated)A matching connection is inserted into the connecting pipe section 23. A restorable or elastic contact piece 24 is arranged in the connecting pipe section 23. By inserting the matching connection into the connecting pipe section 23, the matching connection and the restorable contact piece 24 are brought into contact in a restorable manner, thereby electrically connecting the matching connection and the socket connection 18. [Bracket 25]

[0019] As this is in Fig. As shown in Figure 6, two sheathed wires 13, which are drawn out of the end of the sheath 15, are held by a clamp or clip 25. The clip 25 is formed into a predetermined shape by pressing a metal sheet material. The clip 25 is essentially W-shaped when viewed from a forward-backward direction. The clip 25 is crimped to wrap around the outer circumferences of the insulating coatings or sheaths 17 of the respective sheathed wires 13. The clip 25 includes crimping pieces 26, which are spaced apart in the forward-backward direction. By crimping the crimping pieces 26 of the clip 25 onto the two sheathed wires 13, the relative positions of the two sheathed wires 13 are maintained. [Stranded wire 14]

[0020] The stranded wire 14 is formed by braiding or twisting a plurality of thin metal wires into a tube. A portion of the stranded wire 14, which is exposed from the end of the sheath 15, is folded towards the end of the sheath 15 and overlapped on the outside of the sheath 15. [Sleeve 27]

[0021] As this is in Fig. 3, Fig. 4 to Fig. As shown in Figure 5, a sleeve 27 is crimped to wrap or wind around the outer circumference of the sheath 15 outside the end of the sheath 15 and inside the stranded wire 14, which overlaps the end of the sheath 15. The sleeve 27 is formed by pressing a metal sheet into a predetermined shape. The sleeve 27 is in the form of an elongated plate. One of the longitudinal end parts of the sleeve 27 has a pointed or comb shape, and the other has a trough shape when viewed laterally.

[0022] The sleeve 27 is or is crimped onto the outer circumference of the covering 15, with the two end parts of the sleeve 27 being directed towards each other by a distance or gap. [Dielectric 19]

[0023] As this is in Fig. 7, Fig. 8 to Fig. As shown in Figure 9, the socket terminals 18 are surrounded by the dielectric 19. The dielectric 19 is in the form of a rectangular parallelepiped extending in the forward-backward direction. The dielectric 19 comprises a lower dielectric 28, which is open at the top and located on a lower side, and an upper dielectric 29, which is assembled with the lower dielectric 28 from above. The lower and upper dielectrics 28 and 29 are formed by injection molding an insulating synthetic resin. The lower and upper dielectrics 28 and 29 are integrally locked in place by a restorable locking mechanism of locking claws 30, which extend outwards from the side edges.The lower dielectric 29 is assembled with the edges of the upper dielectric 29 and with resiliently deformable sections 31 that receive a locking mechanism. These sections 31 are formed at positions on the lower dielectric 28 corresponding to the locking claws 30. The locking sections 31 are essentially gate-shaped. When the lower and upper dielectric 28 and 29 are assembled, cavities 32 are formed to receive the socket terminals 18, extending in the forward-backward direction within the dielectric 19. In this embodiment, a plurality of cavities 32 (two in this embodiment) are formed side by side in a lateral direction. [First outer conductor 33]

[0024] As this is in Fig. 10 and Fig. As shown in Figure 14, the first outer conductor 33 is formed by pressing a metal sheet material into a predetermined shape. Any metal, such as copper, a copper alloy, aluminum, or an aluminum alloy, can be selected as the metal that constitutes or forms the first outer conductor 33 according to the requirements. The first outer conductor 33 comprises a tubular section 35 in the form of a rectangular or right-angled tube extending in the forward-backward direction, a connecting plate section 36 arranged behind the tubular section 35 in the form of an elongated plate extending in the forward-backward direction and overlapping the stranded wire 14, which is folded on the outer circumference of the sheath 15, and a first coupling orCoupling section 37, which couples the tubular section 35 and the connecting plate section 36 in the forward-backward direction.

[0025] The inner shape of the tubular section 35 is the same as, or slightly larger than, the outer shape of the dielectric 19. The dielectric 19 is inserted into the tubular section 35 from the rear. The tubular section 35 comprises a bottom wall 35B, a left side wall 35L extending upward from the left side edge of the bottom wall 35B, a right side wall 35R extending upward from the right side edge of the bottom wall 35B, and an upper wall 35U. The upper wall 35U is configured such that the right end edge of a left half 35UL, extending to the right from the upper end edge of the left side wall 35L, and the left end edge of a right half 35UR, extending to the left from the upper end edge of the right side wall 35R, abut each other near a center point in the lateral direction.Each of the right end edge of the left half 35UL and the left end edge of the right half 35UR is formed with (a) substantially trapezoidal projection(s) 38 and (a) substantially trapezoidal recess(s) 39, and the opening deformation or deformation of the tubular section 35 is suppressed by a fitting of the projections 38 and the recesses 39.

[0026] Locking or locking pieces 40, which extend in the forward-backward direction and project forward with rear end parts as base parts, are formed at positions near the rear end parts of the left and right side walls 35L, 35R of the tubular section 35. The locking pieces 40 are designed to extend laterally inward toward a front face. Through-holes 41, which remain after cutting and lifting the locking pieces 40 from the left and right side walls 35L, 35R, are formed near the locking pieces 40. The locking pieces 40 are designed to be deformable or resilient in the lateral direction. The dielectric 19 is held in place in the tubular section 35 by locking the front end parts of the locking pieces 40 to the locking pieces 40.Locking recesses 42, which are formed at positions near a rear end part of the dielectric 19, are held back and retained from the rear.

[0027] The bottom wall 35B of the tubular section 35 is formed with a marking 43, which projects downwards at a position slightly in front of the locking pieces 40 and the through-holes 41 and near a lateral center or midpoint. The marking 43 is formed by striking the bottom wall 35B of the tubular section 35 downwards.

[0028] The first coupling section 37, which extends obliquely downwards towards a rear side, is formed on the rear end edge of the bottom wall 35B of the tubular section 35, a substantially half region of the rear end edge of the left side wall 35L of the tubular section 35 from below, and a substantially half region of the rear end edge of the right side wall 35R of the tubular section 35 from below. The first coupling section 37 has a curved surface shape, convex downwards, when viewed from the rear.

[0029] The connecting plate section 36, which extends posteriorly from near the lateral center, is formed on the posterior end edge of the first coupling section 37. The connecting plate section 36 is in the form of a plate that is elongated or elongated in the forward-backward direction. The upper and lower surfaces of the connecting plate section 36 have a gently convex downward curve. [Second outer conductor 34]

[0030] As this is in Fig. 13 and Fig. As shown in Figure 14, the second outer conductor 34 is formed into a predetermined shape by pressing a metal sheet material. Any metal, such as copper, a copper alloy, aluminum, or an aluminum alloy, can be selected as the metal forming the second outer conductor 34, according to the requirements.The second outer conductor 34 includes a front crimping section 44 (example of a tube crimping section) which is to be crimped onto the outer circumference of the tubular section 35, a rear crimping section 45 (example of a shield crimping section) which is to be crimped onto the stranded wire 14 which is folded onto the end of the sheath 15, and the connecting plate section 36 which overlaps the stranded wire 14, and a second coupling section 46 which couples the front and rear crimping sections 44, 45 in the forward-backward direction.

[0031] The front crimping section 44 includes an upper wall 44U, a left side wall 44L (example of a surrounding section) extending downwards from the left side edge of the upper wall 44U, a right side wall 44R (example of the surrounding section) extending downwards from the right side edge of the upper wall 44U, a left crimping piece 47L extending to the right from a part near a rear end part, from the lower end edge of the left side wall 44L, and a right crimping piece 47R extending to the right from a part near a front end part, from the lower end edge of the right side wall 44R.When the front crimping section 44 is crimped onto the outer circumference of the tubular section 35, the upper wall 44U of the front crimping section 44 covers the upper wall 35U of the tubular section 35 from above, the left side wall 44L of the front crimping section 44 covers the left side wall 35L of the tubular section 35 from the left, the right side wall 44R of the front crimping section 44 covers the right side wall 35R of the tubular section 35 from the right, and the left and right crimping pieces 47L, 47R of the front crimping section 44 cover the bottom wall 35B of the tubular section 35 from below.

[0032] A gap or space 48 is formed in the forward-backward direction between the left and right crimping pieces 47L, 47R of the front crimping section 44. The width in the forward-backward direction of this gap 48 is equal to or slightly greater than that of the marking 43 of the tubular section 35.

[0033] The front end edge of the left crimping piece 47L can come into contact with the rear end edge of the marking 43 from the front. Furthermore, the rear end edge of the right crimping piece 47R can come into contact with the front end edge of the marking 43 from the rear. In this way, the tubular section 35 and the front crimping section 44 are positioned in the forward-backward direction.

[0034] A locking or locking hole 49, which has a substantially rectangular or right-angled shape when viewed from above, penetrates the upper wall 44U of the front crimping section 44. A locking or locking lance of a connector housing (not illustrated) is locked against a hole edge portion of this locking hole 49.

[0035] The second coupling section 46, which extends backwards, is formed on the rear end edge of the upper wall 44U of the front crimping section 44, the rear end edge of the left side wall 44L of the front crimping section 44, and the rear end edge of the right side wall 44R of the front crimping section 44. The second coupling section 46 has a curved surface shape that is convex upwards when viewed from the rear.

[0036] The rear crimping section 45 is located behind the second coupling section 46. The rear crimping section 45 includes a base plate section 50 extending rearward from the rear end edge of the second coupling section 46, right crimping pieces 51R extending downward from the right end edge of the base plate section 50, and a left crimping piece 51L extending downward from the left end edge of the base plate section 50.

[0037] The base plate section 50 has a substantially rectangular or right-angled shape and a curved surface that convexly upwards when viewed from the rear. A plurality of (four in this embodiment) protrusions 52 project radially inwards from the shielded cable 11 on the rear end edge of the base plate section 50, while being spaced apart from one another in a circumferential direction of the shielded cable 11. The protrusions 52 are curved radially inwards from the shielded cable 11 at a substantially right angle to the rear end edge of the base plate section 50.

[0038] When the rear crimping section 45 is crimped onto the stranded wire 14 and the connection plate section 36, the protrusions 52 are positioned behind a rear end portion of the sleeve 27. The dimensions of the protrusions 52, which project radially inward from the shielded cable 11, are determined or adjusted such that the protrusions 52 can contact the rear end edge of the sleeve 27 from behind when the rear crimping section 45 is crimped onto the stranded wire 14 and the connection plate section 36. In this way, when the shielded cable 11 is pulled backward, the protrusions 52 come into contact with the rear end edge of the sleeve 27, thereby suppressing backward movement of the shielded cable 11.

[0039] A plurality of (two in this embodiment) right crimping pieces 51R extend from the right end edge of the base plate section 50, spaced apart from one another in the forward-backward direction. The right crimping pieces 51R are each provided at the front and rear end portions of the right end edge of the base plate section 50. A right locking section 53R is formed on a tip portion of each right crimping piece 51R. The right locking section 53R is formed by folding the tip portion of the right crimping piece 51R toward an inner surface (toward the stranded wire 14).

[0040] The left crimping piece 51L extends near a central position in the forward-backward direction along the left end edge of the base plate section 50. The width of the left crimping piece 51L in the forward-backward direction is set to be less than the forward-backward distance between the pair of right crimping pieces 51R. A left locking section 53L is formed on a tip portion of the left crimping piece 51L. The left locking section 53L is formed by folding the tip portion of the left crimping piece 51L toward an inner surface (toward the stranded wire 14). [Crimped structure]

[0041] As this is in Fig. As shown in Figure 15, when the front crimping section 44 is crimped onto the outer circumference of the tubular section 35, the marking 43 is accommodated in the space 48 formed between the right and left crimping sections 47L and 47R. The lower surface of the marking 43 can be positioned above or flush with the lower surfaces of the left and right crimping sections 47L and 47R, or it can project further downwards than the lower surfaces of the left and right crimping sections 47L and 47R.

[0042] As this is in Fig. As shown in Figure 1, when the front crimping section 44 is crimped onto the outer circumference of the tubular section 35, the locking elements 40 and the passage holes 41 of the tubular section 35 are covered from the outside in the lateral direction by the left and right side walls 44L, 44R of the front crimping section 44. In this way, the dielectric 19 is prevented from being exposed through the passage holes 41 of the tubular section 35. As a result, it can be suppressed that noise generated in the socket terminals 18 or the cores 16 leaks outwards through the through-holes 41 of the tubular section 35, or that external noise enters the socket terminals 18 or the cores 16 through the through-holes 41 of the tubular section 35.

[0043] When the rear crimping section 45 is crimped onto the stranded wire 14 and the connection plate section 36, the right locking sections 53R are in contact with the left side edge of the connection plate section 36 in a direction along a radial direction of the shielded cable 11. Furthermore, the left locking section 53L is in contact with the right side edge of the connection plate section 36 in a direction along the radial direction of the shielded cable 11. In this way, the opening deformation of the rear crimping section 45 in the radial direction of the shielded cable 11 is suppressed.

[0044] As this is in Fig. As shown in Figure 16, when the front crimping section 44 is crimped onto the outer circumference of the tubular section 35 and the rear crimping section 45 is crimped onto the stranded wire 14 and the connecting plate section 36, a portion of the second coupling section 46 near a lower end overlaps a portion of the first coupling section 37 near an upper end from the outside in the radial direction of the shielded cable 11. In this embodiment, the inner surface of the second coupling section 46 is in direct contact with the outer surface of the first coupling section 37 in a portion where the second coupling section 46 overlaps the outside of the first coupling section 37. [Assembly process of a socket connector structure 10]

[0045] Next, an example of an assembly process for the socket connector structure 10 according to this embodiment is described. The assembly process for the receiving or socket connector structure 10 is not limited to the one described below.

[0046] In the end section of the shielded cable 11, the sheath 15 is stripped or removed over a predetermined length, thereby exposing the stranded wire 14 from the sheath 15. By cutting the wire drum 14 to a predetermined length, the sheathed wires 13 are exposed from the stranded wire 14.

[0047] At the end of the sheathed wire 13, the insulating coating or sheathing 17 is stripped or removed over a predetermined length, thereby exposing the core 16 from the insulating sheathing 17. The wire drum 22 is crimped onto the outer circumference of the core 16, and the insulating drum 21 is crimped onto the outer circumference of the insulating sheath or coating 17, thus connecting the socket terminal 18 to the end of the sheathed wire 13 (see Fig. 3).

[0048] As this is in Fig. 3 and Fig. As shown in Figure 4, the sleeve or socket 27 is fitted onto the end part of the sheath 15 from the outside. By folding the stranded wire 14, which is exposed by the end part of the sheath 15, the stranded wire 14 is laid on the outside of the sleeve 27 in the radial direction of the shielded cable 11 (see Figure 4). Fig. 5).

[0049] As this is in Fig. As shown in Figure 6, the clip or clamp 25 is fitted onto the two sheathed wires 13 from below. As shown in Figure 6, the clip or clamp 25 is fitted onto the two sheathed wires 13 from below. Fig. As shown in Figure 7, the shielded cable 11 is vertically inverted, and the socket connections 18 are arranged from above on the upper wall of the vertically inverted upper dielectric 29. As shown in Figure 7, the shielded cable 11 is vertically inverted, and the socket connections 18 are arranged on the upper wall of the vertically inverted upper dielectric 29. Fig. As shown in Figure 8, the lower dielectric 28 is assembled with the upper dielectric 29 from above. The upper and lower dielectrics 29, 28 are integrally or integrally assembled by the restorable or elastic engagement of the locking sections 31 of the lower dielectric 28 with the locking claws 30 of the upper dielectric 29 (see Figure 8). Fig. 9).

[0050] As this is in Fig. 10 and Fig. As shown in Figure 11, the shielded cable 11 is vertically inverted, and the dielectric 19 is inserted from the rear into the tubular section 35 of the first outer conductor 33. The locking pieces 40 of the first outer conductor 33 are locked from the rear into the locking recesses 42 of the dielectric 19, thereby retaining and holding the dielectric 19 in the tubular section 35. At this time, the connecting plate section 36 of the first outer conductor 33 is overlapped below the stranded wire 14.

[0051] As this is in Fig. As shown in Figure 13, the second outer conductor 34 is vertically inverted, and the first outer conductor 33, the stranded wire 14, and the connecting plate section 36 are arranged on the second outer conductor 34 from above. The front crimping section 44 is crimped onto the outer circumference of the tubular section 35, and the rear crimping section 45 is crimped onto the outer circumferences of the stranded wire 14 and the connecting plate section 36.

[0052] The front crimping section 44 is crimped with the marking 43, which is formed on the bottom wall 35B of the tubular section 35, serving as a marker. By visually confirming the marking 43 on the bottom wall 35B, the crimped position of the second outer conductor 34 can be verified. This ensures that the crimping step of the second outer conductor 34 is efficient and effective. Furthermore, by locating the marking 43 in the space 48 in the forward-backward direction between the left and right crimping sections 47L and 47R, it can be easily confirmed that the second outer conductor 34 has been crimped in the correct position.

[0053] The rear crimping section 45 is crimped such that the left and right crimping pieces 51L and 51R are wound around the outer circumferences of the stranded wire 14 and the connection plate section 36. The left locking section 53L of the left crimping piece 51L is locked to the right side edge of the connection plate section 36, and the right locking sections 53R of the right crimping pieces 51R are locked to the left side edge of the connection plate section 36. In this way, the opening deformation of the rear crimping section 45 is suppressed. By crimping the rear crimping section 45 onto the stranded wire 14 and the connection plate section 36, the stranded wire 14 and the first and second outer conductors 33 and 34 are electrically connected.

[0054] The second coupling section 46 of the second outer conductor 34 is crimped onto the outer circumference of the first coupling section 37 of the first outer conductor 33 in the same step as crimping the front and rear crimping sections 44, 45 of the second outer conductor 34 onto the first outer conductor 33. In this way, the inner surface of the second coupling section 46 can be held in direct contact with the outer surface of the first coupling section 37 in the area where the second coupling section 46 overlaps the outer surface of the first coupling section 37. The connector structure is thus completed. [Functions and effects of the embodiment]

[0055] Next, the functions and effects of this embodiment are described. The socket connector 12 according to this embodiment is connected to the end part of the shielded cable 11, which is configured or constructed such that the outer circumferences of the coated or sheathed wires 13, each containing the core 16 and the insulating sheath 17 surrounding the outer circumference of the core 16, are enclosed by the stranded wire 14, and includes the receiving orThe socket terminals 18, which are to be connected to the cores 16, the first outer conductor 33, which has the tubular section 35 for surrounding the socket terminals 18 in an electrically insulated state from the socket terminals 18, wherein the tubular section 35 is formed with the through-hole 41, and the connecting plate section 36 to be overlapped on the stranded wire 14, and the second outer conductor 34, which has the rear crimping section 45, which is to be crimped onto the stranded wire 14 and the connecting plate section 36 from outside the stranded wire 14 and the connecting plate section 36, and the left and right side walls 44L 44R for covering at least parts of the tubular section 35 from outside the tubular section 35, and the through-hole 41 of the first outer conductor 33 is or is covered by the left and right side walls 44L 44R Side wall 44L, 44R closed or sealed.

[0056] Furthermore, the socket connector structure 10 according to this embodiment includes the shielded cable 11, which is configured such that the outer circumferences of the sheathed wires 13, each comprising the core 16 and the insulating coating or sheathing 17, which surrounds the outer circumference of the core 16, are surrounded by the stranded wire 14, which receives orSocket terminals 18, which are to be connected to the cores 16, which are exposed from the end part of the shielded cable 11, the first outer conductor 33, which has the tubular section 35 for surrounding the socket terminals 18 in an electrically insulated state from the socket terminals 18, wherein the tubular section 35 is formed with the through-hole 41, and the connecting plate section 36, which is to overlap the stranded wire 14, and the second outer conductor 34, which has the rear crimping section 45, which is to be crimped onto the stranded wire 14 and the connecting plate section 36 from outside the stranded wire 14 and the connecting plate section 36, and the left and right side walls 44L, 44R for covering at least parts of the tubular section 35 from outside the tubular section 35, and it is or isThe passage hole 41 of the first outer conductor 33 is closed by the left and right side walls 44L, 44R.

[0057] According to the configurations above, the through-hole 41 formed in the first outer conductor 33 is closed by the left and right side walls 44L, 44R of the second outer conductor 34. Since the ingress of noise from the outside and the leakage of noise to the outside through the first and second outer conductors 33, 34 can be suppressed in this way, the shielding performance of the socket connector 12 and the socket connector structure 10 can be improved.

[0058] Furthermore, according to this embodiment, the socket terminals 18 are surrounded by the insulating dielectric 19, the tubular section 35 of the first outer conductor 33 is formed with the locking pieces 40, which project inwards from the tubular section to hold the dielectric 19, and the passage hole 41 is formed near the locking pieces 40.

[0059] According to the configuration above, the dielectric 19 in the tubular section 35 can be locked in place by the locking pieces 40. Furthermore, since the through-hole 41, which is formed near the locking pieces 40, is closed by the left and right side walls 44L, 44R, the shielding performance of the socket connector 12 and the socket connector structure 10 can be improved. <Zweite Ausführungsform>

[0060] A second embodiment relating to the technology disclosed in this description is described with reference to Fig. 17, Fig. 18, Fig. 19, Fig. 20, Fig. 21, Fig. 22, Fig. 23, Fig. 24, Fig. 25 to Fig. 26. In a connector structure 110 (example of the connector structure) according to this embodiment, a connector 112 (example of the connector) is connected to one end of a shielded cable 11. In the following description, a Z direction, a Y direction, and an X direction are each designated as an upward direction, a forward direction, and a leftward direction, respectively. Only some of a plurality of links or elements may be designated by a reference numeral, and the other links may or may not be designated by a reference numeral. [Connector 112]

[0061] The connector 112 includes plug terminals 118 (example of the inner conductor), an insulating dielectric 119 for surrounding the outer circumferences of the plug terminals 118, and an outer conductor 20 for surrounding the outer circumference of the dielectric 119. The outer conductor 20 includes a first outer conductor 133 and a second outer conductor 134, which are electrically connected to the first outer conductor 133. [118 connectors]

[0062] As this is in Fig. As shown in Figure 18, the connector 118 is formed by pressing a metal sheet material into a predetermined shape. Any metal, such as copper, a copper alloy, aluminum, or an aluminum alloy, can be selected as the metal that forms the connector 118 according to the requirements. The connector 118 is connected to the end of each sheathed wire 13. The connector 118 includes an insulation drum 121, which is crimped to wrap around the outer circumference of the insulating coating 17 of the sheathed wire 13; a wire drum 122, which is connected in front of the insulation drum 121 and crimped to wrap around the outer circumference of the core 16; and a flat connector 123, which is connected in front of the wire drum 122.is connected and is to be inserted into a connecting pipe section of a matching or coordinated connection (not illustrated). By inserting the flat plug 123 into the connecting pipe section, the coordinated connection and the plug connection 118 are electrically connected. [Dielectric 119]

[0063] As this is in Fig. 19, Fig. 20 to Fig. As shown in Figure 21, the connector terminals 118 are surrounded by the dielectric 119. The dielectric 119 is in the form of a rectangular parallelepiped extending in a forward-backward direction. The dielectric 119 comprises a lower dielectric 128, which is open at the top and located on one side, and an upper dielectric 129, which is assembled with the lower dielectric 128 from above. The lower and upper dielectrics 128 and 129 are formed by injection molding an insulating synthetic resin. The lower and upper dielectrics 128, 129 are integrally or integrally locked by a restorable locking mechanism of locking claws 130, which project outwards from the side edges of the upper dielectric 129, and restorable deformable sections that receive a locking mechanism.Locking receiving sections 131 are assembled, which are formed at positions of the lower dielectric 128 corresponding to the locking claws 130. The locking receiving sections 131 are essentially gate-shaped. When the lower and upper dielectric 128, 129 are assembled, cavities 132 are formed for receiving the plug contacts 118, extending in the forward-backward direction in the dielectric 119. In this embodiment, a plurality of (two in this embodiment) the cavities 132 are formed side by side in a lateral direction. [First outer conductor 133]

[0064] As this is in Fig. 22 and Fig. As shown in Figure 26, the first outer conductor 133 is formed by pressing a metal sheet material into a predetermined shape. Any metal, such as copper, a copper alloy, aluminum, or an aluminum alloy, can be selected as the metal that forms the first outer conductor 133 according to the requirements. The first outer conductor 133 comprises a tubular section 135 in the form of a rectangular tube extending in the forward-backward direction, a connecting plate section 136 arranged behind the tubular section 135 in the form of an elongated plate extending in the forward-backward direction and overlapping the stranded wire 14, which is folded on the outer circumference of the sheath 15, and a first coupling or connecting element.Coupling section 137, which couples the tubular section 135 and the connecting plate section 136 in the forward-backward direction.

[0065] The inner shape of the tubular section 135 is the same as, or slightly larger than, the outer shape of the dielectric 119. The dielectric 119 is inserted into the tubular section 135 from the rear (see Fig. 22). The tubular section 135 comprises a bottom wall 135B, a left side wall 135L extending upwards from the left side edge of the bottom wall 135B, a right side wall 135R extending upwards from the right side edge of the bottom wall 135B, and an upper wall 135U. The upper wall 135U is configured such that the right end edge of a left half 135UL, extending to the right from the upper end edge of the left side wall 135L, and the left end edge of a right half 135UR, extending to the left from the upper end edge of the right side wall 135R, abut each other near a center point in the lateral direction. The right end edge of the left half 135UL and the left end edge of the right half 135UR are each formed with essentially trapezoidal projections or extensions 138 and essentially trapezoidal depressions or recesses 139, and the opening deformation orDeformation of the tubular section 135 is suppressed by fitting the projections 138 and the recesses 139.

[0066] Rear locking elements 140B, extending in the forward-backward direction and projecting forward with rear end sections as base sections, are formed at positions near the rear end sections of the left and right side walls 135L, 135R of the tubular section 135. The rear locking elements 140B are designed to extend laterally inward or inward toward a front face. Rear through-holes 141B, which remain after cutting and lifting the locking elements 140B from the left and right side walls 135L, 135R, are formed near the rear locking elements 140B. The rear locking elements 140B are designed to be resilient or elastically deformable in the lateral direction.The dielectric 119 is held and retained from behind in the tubular section 135 by locking the front end parts of the rear locking pieces 140B to rear locking recesses 142B, which are formed at positions near a rear end part of the dielectric 119.

[0067] A front locking element 140F, extending in the forward-backward direction and projecting backward with a front end portion as a base portion, is formed at a position near a central or midpoint in the forward-backward direction of the left half 135UL of the tubular section 135. The front locking element 140F is designed to extend inward from the tubular section 135 toward a rear side. A front through-hole 141F, which remains after cutting and lifting the front locking element 140F from the bottom wall 135B, is formed near the front locking element 140F. The rear locking element 140B is deformable in the vertical direction and capable of rebound.The dielectric 119 is held back or retained in the tubular section 135 by locking a rear end part of this front locking piece 140F to a front locking recess or indentation 142F, which is formed near a central position in the forward-backward direction of the dielectric 119.

[0068] The bottom wall 135B of the tubular section 135 is formed with a lower marking 143L, which projects downwards at a position slightly in front of the rear locking pieces 140B and the rear through-holes 141B and near a lateral center. The lower marking 143L is formed by striking or impacting the bottom wall 135B of the tubular section 135 downwards.

[0069] The upper wall 135U of the tubular section 135 is formed with a plurality of (two in this embodiment) upper markings 143U, which project upwards and are arranged side by side, while being spaced apart from each other in the lateral direction at essentially the same position as the rear locking pieces 140B and the rear through-holes 141B in the forward-backward direction. The upper markings 143U are formed by striking or impacting the upper wall 135U of the tubular section 135 upwards. Each upper marking 143U has a cylindrical shape. [Second outer conductor 134)

[0070] As this is in Fig. 24 and Fig. As shown in Figure 26, the second outer conductor 134 is formed by pressing a metal sheet material into a predetermined shape. Any metal, such as copper, a copper alloy, aluminum, or an aluminum alloy, can be selected as a metal that forms the second outer conductor 134 according to the requirements.The second outer conductor 134 includes a front crimping section 144 (example of a tube crimping section) which is to be crimped onto the outer circumference of the tubular section 135, a rear crimping section 145 (example of a shield crimping section) which is to be crimped onto the stranded wire 14 which is folded onto the end of the sheath 15, and the connecting plate section 136 which overlaps the stranded wire 14, and a second coupling section 146 which couples the front and rear crimping sections 144, 145 in the forward-backward direction.

[0071] The front crimping section 144 includes an upper wall 144U, a left side wall 144L (example of the surrounding section) extending downwards from the left side edge of the upper wall 144U, a right side wall 144R (example of the surrounding section) extending downwards from the right side edge of the upper wall 144U, a left crimping piece 147L extending to the right from a part near a rear end part, from the lower end edge of the left side wall 144L, and a right crimping piece 147R extending to the left from a part near a rear end part, from the upper end edge of the right side wall 144R.When the front crimping section 144 is crimped onto the outer circumference of the tubular section 135, the upper wall 144U of the front crimping section 144 covers the upper wall 135U of the tubular section 135 from above, the left side wall 144L of the front crimping section 144 covers the left side wall 135L of the tubular section 135 from the left, the right side wall 144R of the front crimping section 144 covers the right side wall 135R of the tubular section 135 from the right, and the left and right crimping pieces 147L, 147R of the front crimping section 144 cover the bottom wall 135B of the tubular section 135 from above.

[0072] A gap or clearance 148 (corresponding to a recess or indentation) is formed in the forward-backward direction between the left and right crimping pieces 147L, 147R of the front crimping section 144. The width of this clearance or gap 148 in the forward-backward direction is equal to or slightly greater than that of the lower marking 143L of the tubular section 135.

[0073] When the front crimping section 144 is crimped onto the outer circumference of the tubular section 135, the lower marking 143L is accommodated in the recess 148 formed between the left and right crimping sections 147L, 147R. The lower surface of the lower marking 143L may be positioned above, or flush with, the lower surfaces of the left and right crimping sections 147L, 147R, or project further downwards than the lower surfaces of the left and right crimping sections 147L, 147R.

[0074] The rear end edge of the left crimping piece 147L can come into contact with the front end edges of the upper markings 143U from the front. Furthermore, the front end edge of the right crimping piece 147R can come into contact with the rear end edges of the upper markings 143U from the rear. In this way, the tubular section 135 and the front crimping section 144 are positioned in the forward-backward direction.

[0075] Recesses or indentations 160 are formed at positions corresponding to the upper markings 143U when the front crimping section 144 is crimped onto the outer circumference of the tubular section 135, at positions near a rear end portion of the upper wall 144U of the front crimping section 144. The recesses 160 are designed to pass through the upper wall 144U. The inner shapes of the recesses 160 are circular when viewed from below and are set to be the same as, or slightly larger than, the outer shapes of the upper markings 143U. When the front crimping section 144 is crimped onto the outer circumference of the tubular section 135, the upper markings 143U are inserted into the recesses 160.The upper surfaces of the upper markings 143U may be located below the upper surface of the upper wall 144U, or flush with the upper surface of the upper wall 144U, or may project further upwards than the upper surface of the upper wall 144U.

[0076] A locking or locking hole 149, which has a substantially rectangular or right-angled shape when viewed from above, penetrates the bottom wall 144B of the front crimping section 144 at a position slightly forward of the recesses 160. A locking or locking lance of a connector housing (not illustrated) is locked against a hole edge portion of this locking hole 149.

[0077] When the front crimping section 144 is crimped onto the outer circumference of the tubular section 135, the rear locking pieces 140B and the rear through-holes 141B of the tubular section 135 are covered from the outside in the lateral direction by the left and right side walls 144L, 144R of the front crimping section 144 (see also Fig. 24 and Fig. 25). In this way, the dielectric 119 is prevented from being exposed through the rear through-holes 141B of the tubular section 135. As a result, noise generated in the socket terminals 118 or cores 16 can be prevented from leaking or escaping to the outside through the rear through-holes 141B of the tubular section 135, or from entering the socket terminals 118 or cores 16 through the rear through-holes 141B of the tubular section 135.

[0078] When the front crimping section 144 is crimped onto the outer circumference of the tubular section 135, the front locking piece 140F and the front through-hole 141F of the tubular section 135 are covered from below by the upper wall 144U of the front crimping section 144 (see also Fig. 24 and Fig. 25). In this way, the dielectric 119 is prevented from being exposed through the front through-hole 141F of the tubular section 135. As a result, noise generated in the socket terminals 118 or cores 16 can be prevented from leaking to the outside through the front through-hole 141F of the tubular section 135, or external noise can be prevented from entering the socket terminals 118 or cores 16 through the front through-holes 141F of the tubular section 135.
