Description

Technical Field

[0001] The present invention relates to a shield connector.

Background Art

[0002] Conventionally, as disclosed in Patent Documents 1 and 2 for example, a shield connector is configured such that a terminal fitting (terminal) connected to an electric wire is inserted into a housing from the rear, and a metal shield shell fixed to a shield member that collectively surrounds a plurality of electric wires is attached to the outer periphery of the housing.

[0003] In the shield connector of Patent Document 1, an extension portion in a form where a region on the outer peripheral side of the electric wire rather than the electric wire itself on the lead-out surface of the electric wire extends rearward from the shield shell is formed in a rubber plug holder for preventing the rubber plug fitted to the rear end portion of the housing in a state where the electric wire penetrates through the electric wire from coming off.

[0004] Therefore, when the electric wire deviates from the normal wiring path and is bent forward, the electric wire is folded back at the rear end of the extension portion that is separated from the shield shell. Thus, even when the bent electric wire abuts against the shield shell, the electric wire at that time is in a posture along the outer peripheral surface of the shield shell. Therefore, there is no risk of damage even if the resin coating hits the edge at the rear end of the shield shell.

[0012] Hereinafter, examples of embodiments according to the present invention will be described with reference to the drawings. (Embodiment) Figure 1 is a perspective view showing the shielded connector 1 according to one embodiment of the present invention with the shield shell 60 removed. Figure 2 is an exploded perspective view of the shielded connector 1 shown in Figure 1. In addition, in this specification, the front-back direction, up-down direction, and left-right direction of the shield connector 1 shall follow the directions of the arrows shown in FIGS. 1 and 2. That is, the front-back direction is the direction along the connector fitting direction of the shield connector 1, and the side where it is fitted to the fitting portion of the fixed portion is defined as the front of the housing 10. Also, the up-down direction is the extending direction of the shield wire 44 orthogonal to the connector fitting direction of the shield connector 1, and the leading-out direction of the shield wire 44 is defined as the downward direction. Further, the left-right direction is the connector width direction along the longitudinal direction of the substantially oval cross-section of the fitting portion 22 orthogonal to the connector fitting direction.

[0013] As shown in FIGS. 1 and 2, the shield connector 1 according to this embodiment has a housing 10, four terminal wires 40, a cover 30, and a shield shell 60. This shield connector 1 is, for example, a connector used for a power supply circuit such as an inverter or a motor of a vehicle such as a hybrid vehicle or an electric vehicle. This shield connector 1 is fitted and electrically connected to a mating connector (fitting portion) provided in a shield case (fixed portion), not shown, such as an inverter or a motor.

[0014] As shown in FIGS. 1 and 2, the housing 10 is a substantially L-shaped housing having a fitting portion 22 that houses the tab terminals (terminals) 41 of the terminal wires 40 and is fitted to the mating connector, and four wire introduction portions 12 through which the terminals of the shield wire 44 connected to the tab terminals 41 are introduced from the downward direction intersecting the fitting direction (front-back direction in FIG. 1) of the fitting portion 22.

[0015] The fitting portion 22 is formed in a bottomed cylindrical shape having a substantially oval cross-section and protrudes forward in the fitting direction with the mating connector in the housing 10. Four terminal insertion holes 14 (see FIG. 2) are formed side by side in the left-right direction (connector width direction) at the bottom of the fitting portion 22.

[0016] The four wire entry points 12 extend downward, intersecting the mating direction with the mating connector of the housing 10, and are arranged side by side in the left-right direction. Each of these wire entry points 12 has a wire insertion hole 12a through which the shield wire 44 is inserted (see Figure 8).

[0017] As shown in Figure 2, the housing 10 has a recessed housing portion 13 formed at the rear opposite the fitting portion 22, with an opening 16. A cover 30 is assembled to the opening 16 at the rear of the housing 10 opposite the fitting portion 22. Both the housing 10 and the cover 30 are molded from an electrically insulating synthetic resin.

[0018] When the cover 30 is assembled to the housing 10, the opening 16, which is the mounting hole for the terminal-equipped electric wire 40, is covered by the cover 30. Multiple locking claws 15 are provided protruding from the outer circumferential surface 10a of the housing 10. In addition, a locking projection 17 is provided protruding from the upper center of the outer circumferential surface 10a.

[0019] As shown in Figure 2, the cover 30 is formed in a substantially rectangular plate shape and is assembled to the opening 16 of the housing 10 from the rear side via an annular sealing member 50. The sealing member 50 is attached to the outer sealing surface of the cover 30 and provides a waterproof seal between the opening 16 of the housing 10 and the cover 30.

[0020] As a result, the opening 16 of the housing 10's dwelling section 13 is sealed watertight by the cover 30. The cover 30 has a plurality of locking pieces 35 formed on its periphery, each having a locking hole. When the cover 30 is assembled to the housing 10, the locking claws 15 formed on the housing 10 fit into the locking holes of these locking pieces 35. Each locking piece 35 is then locked by the locking claws 15, holding the cover 30 in the assembled state relative to the housing 10.

[0021] As shown in Figures 2 and 3, the terminal-equipped electric wire 40 is composed of a shielded electric wire 44, a tab terminal (terminal) 41 connected to the conductor end of the shielded electric wire 44, a shield terminal 43 connected to the braid (shielding member) 44c of the shielded electric wire 44, and first and second sealing packings 45 and 46 that provide a watertight seal between the electric wire introduction section 12 of the housing 10 and the shielded electric wire 44.

[0022] The shielded wire 44 is configured as a coaxial cable consisting of a core wire 44a arranged from the center, an inner sheath 44b covering the core wire 44a, a conductive braid 44c covering the inner sheath 44b, and an outer sheath (wire coating) 44d covering the braid 44c (see Figure 8).

[0023] The tab terminal 41 is formed from a conductive metal material such as copper, copper alloy, aluminum, or aluminum alloy. This tab terminal 41 is crimped onto the exposed core wire at the end of the shielded wire 44 and electrically connected to the shielded wire 44. This tab terminal 41 is inserted into the electrical connection portion of the mating terminal (not shown) provided on the mating connector, and an electrical connection is made.

[0024] The terminal-equipped wire 40, which is assembled to the housing 10, has its shielded wire 44 passed through the wire insertion hole 12a of the wire introduction section 12, and its tab terminal 41 is inserted into the terminal insertion hole 14 of the mating section 22 and housed in the terminal housing chamber. In this way, the tab terminal 41 of the terminal-equipped wire 40 is fixed to the mating section 22 of the housing 10.

[0025] Furthermore, each shielded wire 44 of the terminal-equipped wire 40 is fitted with a shield terminal 43 and first and second sealing packings 45 and 46. The shield terminal 43 is made of a conductive metal and, as shown in Figure 4, is configured as a stepped cylindrical shape with multiple (for example, three) enlarged diameter sections that increase in diameter sequentially from the front end to the rear end. These enlarged diameter sections are, from the front end, a braided crimping section 43a, a first seal contact section 43b, and a second seal contact section 43c.

[0026] Then, the outermost outer sheath 44d of the shield terminal 43 is removed, and the braided 44c is exposed at the end of the outer sheath 44d, which is then fitted onto the shield terminal 43. The outer circumference of the braided crimping portion 43a at the tip of the shield terminal 43 is covered with the folded braided 44c. The outer circumference of the folded braided 44c is crimped and fixed to the outer sheath 44d together with the braided crimping portion 43a by the crimping sleeve 49. As a result, the shield terminal 43 is electrically connected and fixed to the open end of the braided 44c exposed at the end of the shield wire 44.

[0027] As shown in Figure 4, the second seal packing 46 is made of an annular seal rubber and seals the space between the shield terminal 43 connected to the braid 44c of the shield wire 44 and the wire introduction section 12. Multiple inner lip portions 46a are formed on the inner circumference of the second seal packing 46, which elastically adhere to the outer surface of the first seal contact portion 43b of the shield terminal 43. Multiple outer lip portions 46b are formed on the outer circumference of the second seal packing 46, which elastically adhere to the inner wall of the wire insertion hole 12a of the wire introduction portion 12 in which the shield terminal 43 is housed.

[0028] As shown in Figures 5 and 6, the first seal packing 45 is made of a cylindrical seal rubber and seals the space between the shield wire 44 and the shield terminal 43. The first seal packing 45 is integrally formed with an annular water-stopping portion 47 and a small-diameter cylindrical contact prevention portion 48 connected to one open end of the water-stopping portion 47.

[0029] Multiple inner lip portions 47a are formed on the inner circumference of the water-sealing portion 47, which elastically adhere to the outer sheath 44d of the shielded wire 44. Multiple outer lip portions 47b are formed on the outer circumference of the water-sealing portion 47, which elastically adhere to the inner surface of the second seal contact portion 43c of the shield terminal 43.

[0030] The contact prevention portion 48 has an inner diameter that is larger than the inner diameter of the inner lip portion 47a of the water-sealing portion 47 and smaller than the outer diameter of the shield wire 44, and an outer diameter that is smaller than the outer diameter of the outer lip portion 47b of the water-sealing portion 47. Furthermore, the contact prevention portion 48 is configured to have a length that prevents the shield wire 44 led out from the wire outlet end 60a of the shield shell 60 from coming into contact with the edge of the wire outlet end 60a. These shield terminals 43 and the first and second sealing packings 45 and 46 then create a liquid-tight seal between the shield wire 44 and the wire introduction section 12.

[0031] As shown in Figures 1 and 2, the shield connector 1 according to this embodiment includes a shield shell 60 composed of an upper shield shell (first shield shell) 61 assembled from the rear side of the housing 10 and a lower shield shell (second shield shell) 62 assembled from below. The upper shield shell 61 is formed by press-forming a metal plate, and the lower shield shell 62 is formed by die-casting molten metal.

[0032] As shown in Figures 1 and 2, the upper shield shell 61 is formed in a box shape having a substantially rectangular flat bottom plate portion 63 and peripheral walls 65 that are vertically attached to the periphery of the bottom plate portion 63. The bottom plate portion 63 covers the rear surface of the housing 10, and the peripheral walls 65 cover the top surface and left and right sides (sides) of the housing 10. Below the bottom plate portion 63, a first shield terminal clamping portion 73 is provided for clamping the shield terminal 43 of the terminal-equipped wire 40 extending from the wire introduction portion 12 of the housing 10. On the inner surface of the first shield terminal clamping portion 73, four cylindrical surfaces 73a corresponding to the outer surface shape of the shield terminal 43 are formed.

[0033] Furthermore, the upper shield shell 61 is provided with a pair of through holes 69 formed at both ends in the connector width direction below the bottom plate portion 63, a through hole 74 formed in the center of the fixing portion 70 in the connector width direction, and a locking hole 75 formed in the upper center of the peripheral wall 65.

[0034] Furthermore, the upper shield shell 61 is provided with a mounting piece 67 having a hole 67a that protrudes from the left side of the fixing portion 70 of the first shield terminal clamping portion 73, and a mounting piece 68 having a hole 68a that protrudes from the upper right corner of the peripheral wall 65.

[0035] As shown in Figure 2, the lower shield shell 62 has a second shield terminal clamping portion 71 for clamping the shield terminal 43 of the terminal-equipped wire 40 extending from the wire introduction portion 12 of the housing 10, and covers the portion of the front surface of the housing 10 excluding the fitting portion 22.

[0036] The inner surface of the second shield terminal clamping portion 71 is provided with four terminal insertion recesses 76 for inserting the shield terminals 43 of the terminal-equipped electric wire 40. Furthermore, the inner surface of the lower end of the second shield terminal clamping portion 71 is provided with four wire insertion grooves 77, each communicating with the terminal insertion recesses 76, for inserting the shield wires 44 of the terminal-equipped electric wire 40.

[0037] Furthermore, the lower shield shell 62 is provided with a pair of screw holes 66 formed above the second shield terminal clamping portion 71 corresponding to a pair of through holes 69, and a screw hole 72 formed below the second shield terminal clamping portion 71 corresponding to a through hole 74.

[0038] Next, we will describe how to assemble the shield connector 1 according to this embodiment. First, as shown in Figure 2, the shielded wire 44 of the terminal-equipped wire 40 is passed through the wire entry section 12 of the housing 10, and the tab terminal 41 is pulled out towards the housing section 13. Then, the tab terminal 41 is inserted into the terminal insertion hole 14 of the housing 10.

[0039] Then, the cover 30 is brought close to the housing portion 13 of the housing 10 so as to cover the opening 16 from the rear side, and the locking claws 15 of the housing 10 are locked into the locking pieces 35 of the cover 30. As a result, the sealing member 50 attached to the housing 10 provides a waterproof seal between the opening 16 of the housing 10 and the cover 30.

[0040] Next, the shield shell 60 is attached to the housing 10. First, as shown in Figure 7, the lower shield shell 62 of the shield shell 60 is attached from below so as to cover the wire entry section 12 of the housing 10 and the shield terminal 43 of the terminal-equipped wire 40, and the shield wire 44 is inserted into the wire insertion groove 77. In this case, the portion of the shielded wire 44 that is inserted into the wire insertion groove 77 is covered by the contact prevention portion 48 of the first seal packing 45, so that the outer sheath 44d does not come into direct contact with the lower shield shell 62.

[0041] Next, as shown in Figure 2, the upper shield shell 61 of the shield shell 60 is attached from the rear so as to cover the housing 10 to which the cover 30 is assembled. The upper shield shell 61 is attached to the rear of the housing 10 by first engaging the locking hole 75 with the locking projection 17 of the housing 10, then placing the first shield terminal clamping portion 73 over the wire introduction portion 12 and the shield terminal 43 of the wire with terminal 40, and placing the fixing portion 70 over the wire insertion groove 77.

[0042] The upper shield shell 61 and lower shield shell 62 are then mounted on the housing 10, with the through holes 69 and 74 of the upper shield shell 61 and the screw holes 66 and 72 of the lower shield shell 62 being connected. Subsequently, the upper shield shell 61 and lower shield shell 62 are fixed to the housing 10 by inserting the bolts 81 into the through holes 69 and 74 and screwing them into the screw holes 66 and 72.

[0043] The upper shield shell 61 and the lower shield shell 62 are electrically connected to each other via bolts 81. Furthermore, one end of the braided shield wire 44c of the shield wire 44 is electrically connected to the shield shell 60 by the shield terminal 43 of the terminal-equipped wire 40.

[0044] Furthermore, after the shield connector 1 is mated with the mating connector provided on the shield case, it is fastened and fixed to the shield case by a pair of fixing bolts (not shown) inserted into the holes 68a of the mounting piece 68 of the upper shield shell 61 and the holes 67a of the mounting piece 67, thereby ensuring a secure electrical connection. As a result, the shield connector 1 is covered by the shield shell 60 fixed to the shield case, providing a good electromagnetic shielding effect.

[0045] Next, the operation of the shield connector 1 according to the above embodiment will be described. As shown in Figure 8, in the shield connector 1 according to this embodiment, when the shield shell 60 is attached to the housing 10, the shield shell 60 is fitted onto the outer circumference of the wire entry portion 12 of the housing 10, and the wire exit end 60a of the shield shell 60 extends downward below the open end 12b of the wire entry portion 12.

[0046] Furthermore, the first seal packing 45, which is fitted into the second seal contact portion 43c to seal the space between the shield wire 44 and the shield terminal 43, has a contact prevention portion 48 that extends toward the wire outlet end 60a of the shield shell 60. The contact prevention portion 48 is of a length that prevents the shield wire 44, which is led out from the wire outlet end 60a of the shield shell 60, from coming into contact with the edge of the wire outlet end 60a.

[0047] In other words, when the terminal-equipped wire 40 is assembled to the housing 10 and the housing 10 is covered by the shield shell 60, the contact prevention portion 48 of the first seal packing 45 is of a length that prevents the shield wire 44 led out from the wire outlet end 60a of the shield shell 60 from coming into contact with the edge of the wire outlet end 60a.

[0048] Therefore, as shown in Figure 8, the portion of the shielded wire 44 surrounded by the shield shell 60 is covered by the contact prevention portion 48 of the first seal packing 45, and the outer sheath 44d does not come into direct contact with the shield shell 60. Consequently, even when the shielded wire 44 is shaken due to vibration or the like, wear that occurs on the outer sheath 44d due to direct contact between the shielded wire 44 and the shield shell 60 can be prevented.

[0049] Furthermore, if the shield wire 44 is bent so as to deviate from the regular routing path extending downward (dandonous line in Figure 8), the shield wire 44 will come into contact with the protruding end of the contact prevention portion 48 of the first seal packing 45, and will not come into contact with the edge of the wire outlet end 60a of the shield shell 60. Therefore, the outer sheath 44d of the shield wire 44 is not at risk of being damaged by contact with the edge of the wire outlet end 60a of the shield shell 60.

[0050] Furthermore, the contact prevention portion 48 of the first seal packing 45 fills the gap between the shield wire 44 and the shield shell 60, making it difficult for saltwater or the like to directly come into contact with the watertight portion 47, thereby improving the watertight function of the first seal packing 45.

[0051] Furthermore, the first seal packing 45 according to this embodiment can provide both a sealing function that liquid-tightly seals the space between the shield wire 44 and the shield terminal 43, and a function that prevents wear of the outer sheath 44d due to contact between the shield wire 44 and the shield shell 60, all in a single component. Therefore, the number of components does not increase, and the assembly process does not increase, thus keeping costs down.

[0052] As described above, the shield connector 1 according to this embodiment makes it possible to prevent wear of the outer sheath 44d due to contact between the shield shell 60 and the shield wire 44 without increasing the number of parts.

[0053] (modified version) Figures 9 and 10 are an overall perspective view and a longitudinal cross-sectional view of the modified first seal packing 45A. As shown in Figures 9 and 10, the modified first seal packing 45A integrally molds a water-stopping portion 47A made of an annular sealing rubber and a contact prevention portion 48A made of a resin pipe connected to one open end of the water-stopping portion 47A. For example, the first seal packing 45A can be integrally molded by insert molding or two-color molding. Of course, the water-stopping portion 47A and the contact prevention portion 48A, which are molded separately, may be joined together to form a single unit.

[0054] Multiple inner lip portions 47a are formed on the inner circumference of the water-sealing portion 47A, which elastically adhere to the outer sheath 44d of the shielded wire 44. Multiple outer lip portions 47b are formed on the outer circumference of the water-sealing portion 47A, which elastically adhere to the inner surface of the second seal contact portion 43c of the shield terminal 43.

[0055] The contact prevention portion 48A has an inner diameter that is larger than the inner diameter of the inner lip portion 47a of the water-sealing portion 47A and smaller than the outer diameter of the shield wire 44, and an outer diameter that is smaller than the outer diameter of the outer lip portion 47b of the water-sealing portion 47A. Furthermore, the contact prevention portion 48A is configured to have a length that prevents the shield wire 44 led out from the wire outlet end 60a of the shield shell 60 from coming into contact with the edge of the wire outlet end 60a.

[0056] Therefore, the shielded connector using the modified first seal packing 45A can obtain the same effects and advantages as the shielded connector 1 according to the above embodiment. Furthermore, in the modified first seal packing 45A, the water-stopping portion 47A and the contact prevention portion 48A can be formed from different materials. This allows for maintaining the elasticity of the water-stopping portion 47A while increasing the rigidity or improving the sliding properties of the contact prevention portion 48A, thereby improving design flexibility.

[0057] Furthermore, in the shield connector 1 according to this embodiment, the shield shell 60 is composed of an upper shield shell 61 assembled from the rear side of the housing 10 and a lower shield shell 62 assembled from the lower side of the housing 10. The upper shield shell 61 has a bottom plate portion 63 that covers the rear surface of the housing 10 and a peripheral wall 65 that is vertically attached to the periphery of the bottom plate portion 63 and covers the top surface and left and right sides of the housing 10. Therefore, the shield connector 1 can achieve a good electromagnetic shielding effect with simple assembly.

[0058] Furthermore, in the shield connector 1 according to this embodiment, the first shield terminal clamping portion 73 of the upper shield shell 61 and the second shield terminal clamping portion 71 of the lower shield shell 62 are electrically connected to the braided 44c of the terminal-equipped wire 40 housed in the housing 10 by clamping the shield terminal 43 of the terminal-equipped wire 40. In addition, a terminal insertion recess 76 for inserting the shield terminal 43 and a wire insertion groove 77 for inserting the shield wire 44 are provided in communication on the inner surface of the second shield terminal clamping portion 71.

[0059] Therefore, the upper shield shell 61 and the lower shield shell 62 are fixed to the housing 10 by bolts 81, so that the first shield terminal clamping portion 73 of the upper shield shell 61 and the second shield terminal clamping portion 71 of the lower shield shell 62 clamp the shield terminal 43 of the terminal-equipped wire 40. As shown in Figure 8, the stepped portion formed between the terminal insertion recess 76 and the wire insertion groove 77 in the second shield terminal clamping portion 71 restricts the movement of the shield terminal 43, which is connected and fixed to the shield wire 44, toward the wire exit end 60a of the shield shell 60, thereby preventing it from coming loose.

[0060] Furthermore, the present invention is not limited to the embodiments described above, and can be modified, improved, etc., as appropriate. In addition, the material, shape, dimensions, number, placement, etc. of each component in the embodiments described above are arbitrary and not limited, as long as they can achieve the present invention. For example, in the above embodiment, an example was described in which the lower shield shell 62 was formed by die casting, but the lower shield shell may also be formed by press molding.

[0061] Herein, the features of the embodiments of the shielded connector according to the present invention described above are briefly summarized and listed below in [1] to [4]. [1] A housing (10) that accommodates the terminals (tab terminals 41), A shield shell (60) covering the housing (10), The aforementioned terminal (tab terminal 41) is electrically connected to the shielding member (braid 44c) of the shielded wire (44) to which the terminal is connected, and the shield terminal (43) is electrically connected to the shielding member (braid 44c) of the shielded wire (44) to which the terminal is connected, The system includes a first sealing packing (45, 45A) that seals the space between the shielded wire (44) and the shield terminal (43), The first seal packing (45, 45A) has a watertight seal (47, 47A) that seals the space between the shield wire (44) and the shield terminal (43) in a liquid-tight manner, and a cylindrical contact prevention portion (48, 48A) that extends toward the wire outlet end (60a) of the shield shell (60) to prevent contact between the shield wire (44) and the shield shell (60). Shielded connector (1).

[0062] According to the shield connector (1) with the configuration described in [1] above, the portion of the shield wire (44) surrounded by the shield shell (60) is covered by the contact prevention portion (48, 48A) of the first seal packing (45, 45A), so that the outer sheath (44d) does not come into direct contact with the shield shell (60). Therefore, even when the shield wire (44) is shaken by vibration or the like, wear that occurs on the outer sheath (44d) due to direct contact between the shield wire (44) and the shield shell (60) can be prevented. Furthermore, if the shield wire (44) is bent so as to deviate from its regular routing path, the shield wire (44) will come into contact with the protruding end of the contact prevention portion (48, 48A) of the first seal packing (45), and will not come into contact with the edge of the wire outlet end (60a) of the shield shell (60). Therefore, the outer sheath (44d) of the shield wire (44) is not likely to be damaged by contact with the edge of the wire outlet end (60a) of the shield shell (60). Furthermore, the contact prevention portion (48, 48A) of the first seal packing (45, 45A) fills the gap between the shield wire (44) and the shield shell (60), making it difficult for saltwater or the like to directly come into contact with the watertight portion (47, 47A), thereby improving the watertight function of the first seal packing (45, 45A). Furthermore, the first seal packing (45, 45A) in this configuration can fulfill both the sealing function of liquid-tightly sealing the space between the shield wire (44) and the shield terminal (43), and the function of preventing wear of the outer sheath (44d) due to contact between the shield wire (44) and the shield shell (60), all with a single component. Therefore, the number of components does not increase, and the assembly process does not increase, thus keeping costs down.

[0063] [2] The contact prevention portion (48A) is made of a resin pipe integrally molded with the water-stopping portion (47A). The shield connector (1) described in [1] above.

[0064] According to the shield connector (1) with the configuration described in [2] above, the water-sealing portion (47A) and the contact prevention portion (48A) can be formed from different materials. Therefore, while maintaining the elasticity of the water-sealing portion (47A), the rigidity of the contact prevention portion (48A) can be increased or its sliding properties can be improved, thereby increasing the design flexibility.

[0065] [3] The shield shell (60) is composed of a first shield shell (upper shield shell 61) assembled from the rear side of the housing (10) and a second shield shell (lower shield shell 62) assembled from the lower side of the housing (10). The first shield shell (upper shield shell 61) has a bottom plate portion (63) that covers the rear surface of the housing (10) and a peripheral wall (65) that is perpendicular to the periphery of the bottom plate portion (63) and covers the side surface of the housing (10). The shielded connector (1) described in [1] or [2] above.

[0066] According to the shield connector (1) in the configuration described in [3] above, a good electromagnetic shielding effect can be obtained with simple assembly work.

[0067] [4] The first shield terminal clamping portion (73) of the first shield shell (upper shield shell 61) and the second shield terminal clamping portion (71) of the second shield shell (lower shield shell 62) are electrically connected to the shield member (braid 44c) by clamping the shield terminal (43), On the inner surface of the second shield terminal clamping portion (71), a terminal insertion recess (76) for inserting the shield terminal (43) and a wire insertion groove (77) for inserting the shield wire (44) are provided in communication with each other. The shield connector (1) described in [3] above.

[0068] According to the shield connector (1) with the configuration described in [4] above, the first shield shell (upper shield shell 61) and the second shield shell (lower shield shell 62) are fixed to the housing (10), so that the first shield terminal clamping portion (73) of the first shield shell (upper shield shell 61) and the second shield terminal clamping portion (71) of the second shield shell (lower shield shell 62) clamp the shield terminal (43) of the terminal-equipped wire (40). The stepped portion formed between the terminal insertion recess (76) and the wire insertion groove (77) in the second shield terminal clamping portion (71) restricts the movement of the shield terminal (43), which is connected and fixed to the shield wire (44), toward the wire exit end (60a) of the shield shell (60), thereby preventing it from coming loose.
