Description

Electromagnetic Shield Connector

[0001] The present disclosure relates to an electromagnetic shield connector.

[0002] Conventionally, in electric vehicles, hybrid vehicles, etc., electromagnetic shield connectors having an electromagnetic shield function have been used. For example, in Patent Document 1, a shield shell is disposed outside an inner housing that houses a terminal with a shielded wire in which a terminal is connected to the end of a shielded wire, and an outer housing is further disposed outside the shield shell. An electromagnetic shield connector having a multilayer structure is disclosed. Then, a shield member such as a braided wire surrounding the core wire of the shielded wire is electrically connected to the shield shell via a shield sleeve externally fitted to the shielded wire, and further electrically connected to the shield shell of the mating connector to obtain an electromagnetic shielding effect.

[0003] Japanese Unexamined Patent Application Publication No. 2018 - 55833

[0004] By the way, in the electromagnetic shield connector of the conventional structure, since the outer housing is disposed outside the shield shell, the number of parts is large and the assembly work is complicated. Therefore, it is conceivable to integrally mold the outer housing with the shield shell as an insert part. In this case, since it is necessary to provide a conductive portion on the inner surface of the outer housing that exposes the inner peripheral surface of the peripheral wall portion of the shield shell, it is necessary to improve the adhesion between the mold and the inner peripheral surface of the peripheral wall portion of the shield shell to prevent the resin from leaking between the mold and the inner peripheral surface of the peripheral wall portion of the shield shell during molding. However, in order to improve the adhesion between the mold and the inner peripheral surface of the peripheral wall portion of the shield shell to such an extent that resin leakage can be prevented, it is necessary to manufacture the shield shell, which is a press-molded product, with an accuracy exceeding three times the current accuracy, and it was lacking in feasibility.

[0005] Therefore, an electromagnetic shield connector is disclosed that can improve the adhesion between the mold and the inner peripheral surface of the peripheral wall portion of the shield shell without depending on the component accuracy of the shield shell.

[0006] The electromagnetic shield connector of this disclosure comprises a shielded wire with a terminal attached to the end of the shield wire, an inner housing in which the terminal is housed, a shield shell disposed outside the inner housing and surrounding the terminal, and an outer housing molded on the outside of the shield shell as an insert, wherein the shield shell has a peripheral wall portion located inside the outer housing and constituting a conductive portion, and the peripheral wall portion of the shield shell is provided with an expansion / contraction allowance portion that allows expansion and contraction of the peripheral wall portion in the circumferential direction.

[0007] The electromagnetic shielding connector of this disclosure can improve the adhesion between the mold and the inner surface of the peripheral wall of the shield shell, without depending on the precision of the parts of the shield shell.

[0009] <Description of Embodiments of the Disclosure> First, embodiments of the Disclosure will be listed and described. The electromagnetic shield connector of the Disclosure comprises: (1) a shield wire with a terminal attached to the end of the shield wire; an inner housing in which the terminal is housed; a shield shell disposed outside the inner housing and surrounding the terminal; and an outer housing molded on the outside of the shield shell as an insert, wherein the shield shell has a peripheral wall portion located inside the outer housing and constituting a conductive portion, and the peripheral wall portion of the shield shell is provided with an expansion / contraction allowance portion that allows expansion and contraction of the peripheral wall portion in the circumferential direction.

[0010] According to the electromagnetic shielding connector of this disclosure, in a structure in which the outer housing is integrally molded with the shield shell as an insert, the peripheral wall portion of the shield shell, which is located inside the outer housing and constitutes the conductive portion, is provided with an expansion / contraction allowance portion that allows expansion and contraction in the circumferential direction. As a result, when inserting a mold into the peripheral wall portion of the shield shell in order to mold the outer housing with the shield shell as an insert, the expansion and contraction of the expansion / contraction allowance portion allows the inner surface of the peripheral wall portion of the shield shell to be kept in close contact with the mold. In other words, the expansion and contraction of the expansion / contraction allowance portion absorbs the dimensional tolerance between the circumferential dimension of the outer surface of the mold and the circumferential dimension of the inner surface of the peripheral wall portion of the shield shell, so that the inner surface of the peripheral wall portion of the shield shell can always be kept in close contact with the outer surface of the mold. As a result, the adhesion between the mold and the inner surface of the peripheral wall portion of the shield shell can be improved without depending on the precision of the shield shell components. For example, if the circumference of the inner surface of the shield shell's peripheral wall is the same as or slightly smaller than the circumference of the mold's outer surface, the expansion of the expansion / contraction allowance allows the mold to be set into the shield shell in a nearly press-fit state, and the inner surface of the shield shell's peripheral wall can be brought into close contact with the mold's outer surface. Also, if the inner surface of the shield shell's peripheral wall is slightly larger than the circumference of the mold's outer surface, the expansion / contraction allowance caused by the resin pressure during molding will contract the expansion / contraction portion, which can be expected to improve the adhesion between the inner surface of the shield shell's peripheral wall and the mold's outer surface. Therefore, in this embodiment of the electromagnetic shield connector, leakage of resin between the mold and the inner surface of the shield shell's peripheral wall during molding can be advantageously suppressed.

[0011] (2) In (1) above, it is preferable that, before the mold for molding the outer housing is inserted into the shield shell, the circumference of the inner surface of the peripheral wall portion of the shield shell at the position where the expansion / contraction allowance portion of the shield shell is formed is smaller than the circumference of the outer surface of the mold that is inserted into the shield shell when molding the outer housing and the inner surface of the peripheral wall portion faces it. Since the circumference of the inner surface of the peripheral wall portion of the shield shell is smaller than the circumference of the outer surface of the mold that faces the inner surface of the peripheral wall portion of the shield shell, the expansion of the expansion / contraction allowance portion of the shield shell allows the mold to be inserted into the shield shell, and the contraction of the expansion / contraction allowance portion allows the inner surface of the peripheral wall portion of the shield shell to be reliably brought into close contact with the outer surface of the mold. This makes it possible to further improve the contact between the outer surface of the mold and the inner surface of the peripheral wall portion of the shield shell, without depending on the precision of the parts of the shield shell.

[0012] (3) In (1) or (2) above, it is preferable that the expansion / contraction allowance portion of the peripheral wall portion of the shield shell includes a portion in which both circumferential ends of the peripheral wall portion overlap. Since the expansion / contraction allowance portion that allows expansion and contraction of the peripheral wall portion in the circumferential direction is included by including a portion in which both circumferential ends of the peripheral wall portion of the shield shell overlap, it is possible to easily provide an expansion / contraction allowance portion that allows expansion and contraction of the peripheral wall portion in the circumferential direction. Moreover, since it is only necessary to overlap both circumferential ends of the peripheral wall portion of the shield shell, the degree of freedom in adjusting the amount of expansion and contraction of the expansion / contraction allowance portion can be improved without increasing the size of the shield shell.

[0013] (4) In any one of (1) to (3) above, it is preferable that the expansion / contraction allowance portion of the peripheral wall portion of the shield shell includes a slit that penetrates the peripheral wall portion in the thickness direction. Since the expansion / contraction allowance portion that allows expansion and contraction of the peripheral wall portion in the thickness direction is included, it is easy to provide an expansion / contraction allowance portion that allows expansion and contraction of the peripheral wall portion in the circumferential direction. Moreover, since it is only necessary to provide a slit that penetrates the peripheral wall portion of the shield shell in the thickness direction, the degree of freedom in adjusting the amount of expansion and contraction of the expansion / contraction allowance portion can be improved without increasing the size of the shield shell. When the shield shell is composed of two divided parts, by providing an expansion / contraction allowance portion by overlap in the part portion that deforms a large amount when inserted into the mold, and an expansion / contraction allowance portion by slit in the part portion that deforms a small amount when inserted into the mold, it is possible to advantageously achieve both the followability of the expansion / contraction allowance portion and the rigidity of the shield shell.

[0014] <Details of Embodiments of the Disclosure> Specific examples of the electromagnetic shielding connectors of the Disclosure will be described below with reference to the drawings. However, the Disclosure is not limited to these examples and is intended to include all modifications within the meaning and scope of the Claims as indicated by the Claims.

[0015] <Embodiment 1> Hereinafter, an electromagnetic shielding connector 10 of Embodiment 1 of the present disclosure will be described with reference to Figures 1 to 13. The electromagnetic shielding connector 10 includes a shielded wire 16 in which a braided wire 14 is provided around the wire 12 as a shielding member, and the shielded wire 16 is connected to a metal housing 20 of an electrical device such as an inverter, which is the counterpart to the shielding connector, via a shield shell 18. As a result, the braided wire 14 is connected to the ground, and the wire 12 is electromagnetically shielded by the braided wire 14. The electromagnetic shielding connector 10 can be positioned in any orientation within a vehicle, but in the following description, "upper" refers to the upper part in Figure 4, "lower" refers to the lower part in Figure 4, "left" refers to the upper part in Figure 3, "right" refers to the lower part in Figure 3, "front" refers to the left in Figure 3, and "rear" refers to the right in Figure 3. In addition, for multiple identical components, only some components may be given reference numerals, and the reference numerals for other components may be omitted.

[0016] <Electromagnetic Shielding Connector 10> The electromagnetic shielding connector 10 comprises a shielded wire 24 with a terminal 22 attached to the end of a shield wire 16, an inner housing 26 in which the terminal 22 is housed, a shield shell 18 disposed outside the inner housing 26 and covering the area around the terminal 22, and an outer housing 28 molded on the outside of the shield shell 18 as an insert. In Embodiment 1, a pair of shielded wires 24, 24 with terminals are provided, and each shielded wire 24 faces each other at a predetermined distance in the left-right direction.

[0017] <Shielded Wire 16> As shown in Figure 6, in Embodiment 1, a pair of shielded wires 16, 16 are provided, and each shielded wire 16 is configured such that a braided wire 14 serving as a shielding member is provided around the wire 12 as described above. Each wire 12 is a covered wire, and an inner insulating coating 32 made of synthetic resin is fitted around the core wire 30 over substantially the entire length. At the ends of each of these wires 12, the inner insulating coating 32 is stripped off, exposing the core wire 30.

[0018] Braided wire 14 is fitted around the inner insulating sheath 32 of each of these electric wires 12. The braided wire 14 is made of thin metal wires that are braided or twisted together to form a cylindrical shape and is provided over approximately the entire length of the inner insulating sheath 32 of each electric wire 12. An outer insulating sheath 34 made of synthetic resin is fitted around each of these braided wires 14 over approximately the entire length. At the ends of each braided wire 14, the outer insulating sheath 34 is stripped away, and each braided wire 14 is exposed to the outside. Each shielded electric wire 16, configured in this way, is arranged to extend in the front-to-back direction. At the terminal (front end) of each shielded electric wire 16, the core wires 30 are exposed.

[0019] In Embodiment 1, a roughly cylindrical metal underlay ring 36 is fitted onto each electric wire 12 at a predetermined distance behind the core wire 30 exposed at the terminal (front end). The end (front end) of each braided wire 14 is wider than the rear portion, and its diameter is larger. The portion of each braided wire 14 with a larger diameter is located on the outer circumference side of the underlay ring 36 fitted onto each electric wire 12 (each inner insulating sheath 32), and the portion of each braided wire 14 located behind the underlay ring 36 is covered by the outer insulating sheath 34. In other words, the front end of each braided wire 14 is located on the outer circumference side of the underlay ring 36 at a predetermined separation distance, and the portion located on the outer circumference side of the underlay ring 36 is exposed to the outside and not covered by the outer insulating sheath 34.

[0020] Furthermore, as shown in Figure 8 later, each shielded wire 16 has an adhesive tube 38 and a heat-shrinkable tube 40 made of synthetic resin fitted to the portion behind each braided wire 14 that is exposed to the outside. In Embodiment 1, the adhesive tube 38 is provided at a predetermined distance behind the braided wire 14 that is exposed to the outside, and the heat-shrinkable tube 40 is provided at a predetermined distance behind the adhesive tube 38. The adhesive tube 38 can be bonded between the outer insulating coating 34 and the outer housing 28, for example, when the outer housing 28 is molded, for example, to improve the watertightness between the outer insulating coating 34 and the outer housing 28. In addition, by providing the heat-shrinkable tube 40 on the outer circumference of the outer insulating coating 34, damage to each shielded wire 16 due to being sandwiched in a mold (not shown) during the molding of the outer housing 28, for example, can be prevented.

[0021] <Shielded wire with terminals 24> Each shielded wire with terminals 24 is constructed by attaching terminals 22 to each core wire 30 that is exposed to the outside in each shielded wire 16. As shown in Figure 6, each terminal 22 extends in a substantially straight line and extends in a direction perpendicular to the extension direction (front-to-back direction) of each shielded wire 16. That is, each terminal 22 includes a base end portion 42 that is attached to the end of each shielded wire 16 (each exposed core wire 30) and a tip portion 44 that is connected to each base end portion 42 and protrudes in a direction perpendicular to the extension direction of each shielded wire 16. In Embodiment 1, each terminal 22 is fixed to each core wire 30 by welding or the like, so that each terminal 22 protrudes downward from the end of each shielded wire 16. As a result, each shielded wire 24 with terminals is generally L-shaped, and as will be described later, each terminal 22 that protrudes downward is inserted into the mating terminal 148, thereby connecting each terminal 22 and the mating terminal 148 to each other. In other words, in Embodiment 1, the electromagnetic shield connector 10 is the male connector.

[0022] <Inner Housing 26> The inner housing 26 is made of an insulating synthetic resin and, as shown in Figure 7, etc., has a substantially rectangular block shape overall. The base end portion 42 of each terminal 22 is housed in this inner housing 26, and the inner housing 26 is fixed around each base end portion 42, while the tip portion 44 of each terminal 22 protrudes downward from the inner housing 26. In Embodiment 1, the inner housing 26 covers not only the base end portion 42 of each terminal 22, but also the front end portions of each core wire 30 and each inner insulating covering 32 that extend rearward from the base end portion 42. In particular, in Embodiment 1, protective portions 46 are provided that cover both the front and rear surfaces and the bottom surface of the tip portion 44 of each terminal 22, and these protective portions 46 are integrally formed with the inner housing 26. As a result, both the left and right surfaces of the tip portion 44 of each terminal 22 are exposed to the outside, and the mating terminal 148, which will be described later, contacts both the left and right surfaces of each tip portion 44. The provision of such a protective part 46 prevents the worker from unintentionally coming into contact with each terminal 22.

[0023] Furthermore, multiple weight-reducing sections 48 are formed on the outer surface of the inner housing 26, and each of these weight-reducing sections 48 opens onto the outer surface of the inner housing 26. In addition, on the outer surface of the inner housing 26, at positions away from these weight-reducing sections 48, positioning sections 50 are provided to position the shield shell 18 and the inner housing 26 when the shield shell 18 is assembled, as described later. In Embodiment 1, multiple positioning sections 50 are provided on the outer surface of the inner housing 26, in a total of three locations on the front and left and right sides of the inner housing 26. Each positioning section 50 is formed in the shape of a protrusion having a predetermined vertical dimension.

[0024] In Embodiment 1, the inner housing 26 is formed as an integrally molded product (primary molded product 52) ​​that integrally includes each terminal-equipped shielded wire 24. That is, when molding the inner housing 26, the front portion of each terminal-equipped shielded wire 24 is set in the molding cavity of the inner housing 26, and the inner housing 26 is molded in this state, thereby forming an inner housing 26 (primary molded product 52) ​​that integrally includes each terminal-equipped shielded wire 24, as shown in Figure 7.

[0025] <Shield Shell 18> The shield shell 18 has a peripheral wall portion 56 located inside the outer housing 28 and forming a conductive portion 54. The peripheral wall portion 56 of the shield shell 18 is provided with an expansion / contraction allowance portion 58 that allows expansion and contraction of the peripheral wall portion 56 in the circumferential direction. In Embodiment 1, the shield shell 18 includes a first divided shell 60 that covers the base end portion 42 of each terminal 22, and a second divided shell 62 that is fixed to the first divided shell 60 with the tip portions 44 of each terminal 22 inserted through it, thereby forming the shield shell 18. That is, the shield shell 18 is configured as a divided structure of a first divided shell 60 that covers the inner housing 26 from above, and a second divided shell 62 that covers the inner housing 26 from below. As a result, the peripheral wall portion 56 also has a divided structure on both the upper and lower sides, and the peripheral wall portion 56 is composed of a first peripheral wall portion 56a provided on the first divided shell 60 and a second peripheral wall portion 56b provided on the second divided shell 62. The shield shell 18 (first divided shell 60 and second divided shell 62) is made of, for example, a metal with excellent conductivity.

[0026] <First Split Shell 60> The first split shell 60 is generally box-shaped with an opening downwards, and integrally includes a first split sleeve 64 that is connected to the shield member (braided wire 14) exposed at the end (front end) of each shield wire 16. Specifically, the first split shell 60 includes an upper wall portion 66 that covers the inner housing 26 from above, and the above-mentioned first circumferential wall portion 56a that protrudes downward from the outer peripheral edge of the upper wall portion 66. This first circumferential wall portion 56a includes a first front wall portion 68 that protrudes downward from the front end of the upper wall portion 66 and covers the upper part of the inner housing 26 from the front, and a first left wall portion 70 and a first right wall portion 72 that protrude downward from both left and right ends of the upper wall portion 66 and cover the upper part of the inner housing 26 from both the left and right sides. Furthermore, the first divided sleeve 64 is roughly semi-cylindrical in shape so as to overlap with the exposed braided wire 14, and is configured to extend rearward from the rear ends of the upper wall portion 66, the first left wall portion 70, and the first right wall portion 72.

[0027] The first divided shell 60 is formed, for example, by press-forming a single metal sheet into the shape described above, and the upper wall portion 66, the first front wall portion 68, the first left wall portion 70, and the first right wall portion 72 are configured to be substantially flat. The first divided sleeve 64 has substantially semi-cylindrical portions on both the left and right sides so as to overlap each of the left and right braided wires 14, but it may also overlap both the left and right braided wires 14, and may have a shape such as the upper part of an elongated cylindrical shape with the left-right direction as the longitudinal direction.

[0028] Furthermore, the lower ends of the first left wall portion 70 and the first right wall portion 72 are positioned differently in the front-rear direction, with the lower end of the rear portion being positioned higher than the lower end of the front portion. Between the front-rear portion of the first left wall portion 70 and the first right wall portion 72, a recess is formed that opens downward and penetrates each wall portion 70, 72 in the thickness direction (left-right direction). Including this recess, a positioning portion 74 is formed that contacts the positioning portions 50 provided on both the left and right sides of the inner housing 26. Similarly, the first front wall portion 68 is divided in the left-right direction, and a slit 76 is formed between the left and right portions of the first front wall portion 68 that opens downward and penetrates the first front wall portion 68 in the thickness direction (front-rear direction). In Embodiment 1, as will be described later, the above-mentioned expansion / contraction allowance portion 58 is formed including this slit 76. Furthermore, since the positioning portion 50 provided at the front of the slit 76 is inserted into and comes into contact with the positioning portion 50 when the first divided shell 60 is superimposed on the inner housing 26, the slit 76 also functions as a positioned portion that comes into contact with the positioning portion 50.

[0029] Furthermore, the lower ends of the first front wall portion 68, the first left wall portion 70, and the first right wall portion 72 are each provided with a first flange portion 78 that protrudes outward in the thickness direction. That is, the first flange portion 78 protrudes forward from the first front wall portion 68, and the first flange portion 78 protrudes outward in the left-right direction from the first left wall portion 70 and the first right wall portion 72. As described above, the first front wall portion 68, the first left wall portion 70, and the first right wall portion 72 are divided by recesses or slits that constitute the respective positioning portions 74 and 76. Therefore, in Embodiment 1, a total of six first flange portions 78 are formed in the first divided shell 60. Before fixing with the second divided shell 62, some of the first flange portions 78 may have through holes that penetrate each first flange portion 78 in the thickness direction (vertical direction).

[0030] <Second Split Shell 62> The second split shell 62 as a whole has a substantially rectangular cylindrical shape that penetrates in the vertical direction and integrally has a second split sleeve 80 that is connected to the shield member (braided wire 14) exposed at the end (front end) of each shield wire 16. Specifically, the second split shell 62 has the aforementioned second circumferential wall portion 56b which is substantially rectangular cylindrical through which the tip portions 44 of each terminal 22 are inserted, and this second circumferential wall portion 56b has a second front wall portion 82 that covers the lower part of the inner housing 26 from the front, a rear wall portion 84 that covers the lower part of the inner housing 26 from the rear, and a second left wall portion 86 and a second right wall portion 88 that cover the lower part of the inner housing 26 from both the left and right sides. Furthermore, the second divided sleeve 80 is roughly semi-cylindrical in shape so as to overlap with the exposed braided wire 14, and is configured to extend rearward from the rear ends of the rear wall portion 84, the second left wall portion 86, and the second right wall portion 88.

[0031] The second divided shell 62 is formed, for example, by press-forming a single metal sheet into the shape described above, and the walls of the second front wall portion 82, the rear wall portion 84, the second left wall portion 86, and the second right wall portion 88 are configured to be substantially flat. The second divided sleeve 80 has substantially semi-cylindrical portions on both the left and right sides so as to overlap each of the left and right braided wires 14, but it may also overlap both the left and right braided wires 14, for example, and may have a shape such as the lower part of an elongated cylindrical shape with the left-right direction as the longitudinal direction.

[0032] Furthermore, the upper ends of the second left wall portion 86 and the second right wall portion 88 are positioned differently in the front-rear direction, with the upper end of the rear portion being higher than the upper end of the front portion. Between the front-rear portion 86 and the second right wall portion 88, a recess is formed that opens upward and penetrates each wall portion 86, 88 in the thickness direction (left-right direction). Including this recess, a positioned portion 90 is formed that contacts the positioning portions 50 provided on both the left and right sides of the inner housing 26. Similarly, the upper end of the second front wall portion 82 is divided in the left-right direction, and a recess is formed between the left and right portions of the upper end of the second front wall portion 82 that opens upward and penetrates the second front wall portion 82 in the thickness direction (front-rear direction). Including this recess, a positioned portion 90 is formed that contacts the positioning portion 50 provided at the front of the inner housing 26.

[0033] Furthermore, the upper ends of the second front wall portion 82, the second left wall portion 86, and the second right wall portion 88 are each provided with a second flange portion 92 that protrudes outward in the thickness direction. That is, the second flange portion 92 protrudes forward from the second front wall portion 82, and the second flange portion 92 protrudes outward in the left-right direction from the second left wall portion 86 and the second right wall portion 88. As described above, the upper end of the second front wall portion 82, the second left wall portion 86, and the second right wall portion 88 are divided by recesses that constitute each positioning portion 90, so in Embodiment 1, a total of six second flange portions 92 are formed in the second divided shell 62. Before fixing with the first divided shell 60, each second flange portion 92 may have a through hole that penetrates each second flange portion 92 in the thickness direction (vertical direction) at a position corresponding to the through hole provided in each first flange portion 78.

[0034] Furthermore, at the lower ends of the second left wall portion 86 and the second right wall portion 88 of the second divided shell 62, as shown in Figure 10 which will be described later, pin insertion holes 94 are formed that penetrate each wall portion 86 and 88 in the thickness direction (left-right direction) through which positioning pins 142 for positioning and fixing the shield shell 18 in the molding cavity are inserted when the outer housing 28 is molded. In addition, at the lower ends of the second front wall portion 82 and the rear wall portion 84, on both the left and right sides, locking holes 96 are formed that penetrate each wall portion 82 and 84 in the thickness direction (front-back direction) through which locking projections 112 of the exposure prevention cylinder portion 108, which will be described later, are locked.

[0035] <Expansion / Expansion Allowing Section 58> As described above, the peripheral wall portion 56 of the shield shell 18 is provided with an expansion / expansion allowing section 58 that allows expansion and contraction of the peripheral wall portion 56 in the circumferential direction. Here, the second peripheral wall portion 56b (second divided shell 62), which constitutes the lower part of the peripheral wall portion 56, is formed by press-forming a single metal sheet as described above, and the roughly rectangular cylindrical second peripheral wall portion 56b is formed by bending a roughly strip-shaped portion of the metal sheet. As shown in Figure 11, which will be described later, the circumferential ends of this strip-shaped portion overlap at the left-right central portion of the second front wall portion 82, but these circumferential ends are not fixed and relative displacement in the left-right direction is possible. That is, the circumferential expansion and contraction of the second peripheral wall portion 56b is permitted by the relative displacement in the left-right direction at these circumferential ends. In other words, in the second circumferential wall portion 56b that constitutes the circumferential wall portion 56, the expansion / contraction allowable portion 58 includes a portion (overlapping portion 98) in which the circumferential ends of the strip-shaped portion constituting the second circumferential wall portion 56b overlap.

[0036] Furthermore, as will be described later, the first divided shell 60 and the second divided shell 62 are fixed together by overlapping the first flange portion 78 and the second flange portion 92. As a result, the slit 76 provided in the left-right central portion of the first front wall portion 68 of the first divided shell 60 is located above the overlap portion 98 provided in the left-right central portion of the second front wall portion 82 of the second divided shell 62. Consequently, for example, when both circumferential ends of the overlap portion 98 are displaced in a direction that separates them, in other words, when the second circumferential wall portion 56b deforms to stretch in the circumferential direction, the lower opening of the slit 76 deforms to widen along with the displacement of both circumferential ends in the direction that separates them. As a result, the first circumferential wall portion 56a can also be deformed to stretch in the circumferential direction, and the slit 76 provided in the first circumferential wall portion 56a also constitutes an expansion / contraction allowance portion 58.

[0037] Furthermore, in the state before inserting the insertion portion 138 of the mold 136 (described later) into the peripheral wall portion 56 (particularly the second peripheral wall portion 56b) of the shield shell 18, it is preferable that the circumference of the inner peripheral surface 100 of the peripheral wall portion 56 (particularly the second peripheral wall portion 56b) of the shield shell 18 at the formation position of the expansion / contraction allowance portion 58 (slit 76 and overlap portion 98) is smaller than the circumference of the outer peripheral surface 140 of the insertion portion 138 of the mold 136 that faces this inner peripheral surface 100. As a result, as shown in Figure 11 later, when the insertion part 138 is inserted into the second circumferential wall 56b from below, the inner surface of the second circumferential wall 56b and the outer surface 140 of the insertion part 138 come into contact, and the expansion / contraction allowance part 58 allows the second circumferential wall 56b to stretch in the circumferential direction until the circumference of the inner surface 100 of the second circumferential wall 56b and the circumference of the outer surface 140 of the insertion part 138 become equal. In this way, the second circumferential wall 56b undergoes elastic deformation to stretch in the circumferential direction, and the elastic restoring deformation of this elastic deformation acts on the second circumferential wall 56b in a direction that causes it to shrink in the circumferential direction, causing the inner surface 100 of the second circumferential wall 56b and the outer surface 140 of the insertion part 138 to come into close contact. Furthermore, the circumference of the inner surface 100 of the second peripheral wall portion 56b and the circumference of the outer surface 140 of the insertion portion 138 refer to the circumference of the portion that is formed into a rectangular cylinder shape on the mutually opposing inner surface 100 and outer surface 140, and refer to the circumference of the portion that is virtually formed into a rectangular cylinder shape, without considering any local recesses or the like.

[0038] <Shield Sleeve 102> The shield shell 18 is formed when the first divided shell 60 and the second divided shell 62 are superimposed on the inner housing 26 from both the upper and lower sides and fixed to each other. At the same time, the first divided sleeve 64 and the second divided sleeve 80 are superimposed on the shield member (braided wire 14) and fixed to each other, thereby forming the shield sleeve 102 fixed to the braided wire 14.

[0039] Specifically, the first divided shell 60 is superimposed on the inner housing 26 from above, positioned relative to the inner housing 26, by inserting the positioning portion 50 of the inner housing 26 into the concave positioning portions 74 and slits 76 provided on the front and left and right sides. Similarly, the second divided shell 62 is superimposed on the inner housing 26 from below, positioned relative to the inner housing 26, by inserting the positioning portion 50 into the concave positioning portions 90 provided on the front and left and right sides. In other words, the first divided shell 60 and the second divided shell 62 are positioned and arranged so that they can be fixed to each other around the inner housing 26 by the positioning portions 74, 76, and 90 contacting the positioning portion 50. Furthermore, when the first divided shell 60 and the second divided shell 62 are superimposed on the inner housing 26 from both the upper and lower sides, the first flange portions 78 of the first divided shell 60 and the second flange portions 92 of the second divided shell 62 are superimposed on each other in the vertical direction.

[0040] The method of fixing the first divided shell 60 and the second divided shell 62 is not limited, but in Embodiment 1, the first flange portions 78 and second flange portions 92 that overlap each other are fixed together by crimping. As a result, as shown in Figure 9, when the first divided shell 60 and the second divided shell 62 are fixed together to form the shield shell 18, a plurality of crimp portions 104 are formed spanning each first flange portion 78 and each second flange portion 92. If through holes are provided in each first flange portion 78 and each second flange portion 92 at corresponding positions, the first divided shell 60 and the second divided shell 62 may be positioned relative to each other using, for example, pins (not shown) inserted through these through holes.

[0041] The first split sleeve 64 extending rearward in the first split shell 60 and the second split sleeve 80 extending rearward in the second split shell 62 are inserted from the front into the annular gap radially between each underlay ring 36 and each braided wire 14 in each terminal-equipped shielded wire 24. In Embodiment 1, the first split sleeve 64 and the second split sleeve 80 are each shaped to have substantially semi-cylindrical portions on both the left and right sides, and these first split sleeve 64 and the second split sleeve 80 are superimposed in the vertical direction to form substantially cylindrical portions on both the left and right sides. The method of fixing the first split sleeve 64 and the second split sleeve 80 is not limited, but in Embodiment 1, as shown in Figure 9, etc., a crimping ring 106 is fitted onto the substantially semi-cylindrical portions of the first split sleeve 64 and the second split sleeve 80 and crimped to fix them in place. In other words, the shield sleeve 102 is formed by the first divided sleeve 64 and the second divided sleeve 80 being crimped and fixed by the crimping rings 106 in the radial gap between each underlay ring 36 and each braided wire 14.

[0042] Each crimping ring 106 is made of metal, for example, and is fitted onto the outer circumference of each braided wire 14, thereby forming a substantially cylindrical portion on both the left and right sides of the shield sleeve 102, and pressing each braided wire 14 against the substantially cylindrical portion of the shield sleeve 102. As a result, each braided wire 14 is electrically connected to the shield sleeve 102, and consequently, each braided wire 14 is electrically connected to the shield shell 18.

[0043] <Exposure prevention cylinder part 108> As shown in FIG. 9, in the state where the shield shell 18 is fixed to the inner housing 26, the tip part 44 of each terminal 22 protrudes below the shield shell 18 (second divided shell 62). In Embodiment 1, the electromagnetic shield connector 10 includes an exposure prevention cylinder part 108 that surrounds the tip part 44 of each terminal 22. In particular, in Embodiment 1, a pair of exposure prevention cylinder parts 108, 108 that surround the tip part 44 of each terminal 22 are provided, and each exposure prevention cylinder part 108 is fixed to the second divided shell 62. Each exposure prevention cylinder part 108 is formed of, for example, the same material as the shield shell 18. By fixing each exposure prevention cylinder part 108 to the second divided shell 62, each exposure prevention cylinder part 108 and the second divided shell 62 (shield shell 18) are electrically connected and assembled so as to be energizable.

[0044] Specifically, each exposure prevention cylinder part 108 has a substantially rectangular cylinder shape penetrating in the vertical direction, and the upper end part of each exposure prevention cylinder part 108 is inserted into and fixed to the lower end part (second peripheral wall part 56b) of the second divided shell 62. Here, engaging parts 110 protruding outward in the left - right direction are provided on the outer wall parts in the left - right direction of each exposure prevention cylinder part 108. Further, locking convex parts 112 protruding outward in the front - rear direction are provided on the wall parts on both sides in the front - rear direction of each exposure prevention cylinder part 108. When the upper end part of each exposure prevention cylinder part 108 is inserted into the lower end part of the second divided shell 62, each engaging part 110 is inserted into each pin insertion hole 94, and each locking convex part 112 is locked to each locking hole 96, each exposure prevention cylinder part 108 is fixed to the second divided shell 62. That is, in Embodiment 1, each exposure prevention cylinder part 108 is fixed by using each pin insertion hole 94 used when molding the outer housing 28.

[0045] Furthermore, each exposure-preventing cylindrical portion 108 is provided with a plurality of elastic contact pieces 114 that are cut and bent upwards above each engaging portion 110 and each locking projection 112. Before each exposure-preventing cylindrical portion 108 is inserted into the second divided shell 62, each of these elastic contact pieces 114 protrudes outward in the front-rear or left-right direction. When each exposure-preventing cylindrical portion 108 is inserted into the second divided shell 62, each elastic contact piece 114 is pressed against the inner circumferential surface of the second divided shell 62 (second circumferential wall portion 56b) and elastically deforms inward in the front-rear or left-right direction. Due to the elastic restoration deformation in response to this elastic deformation, each elastic contact piece 114 is pressed against the inner circumferential surface of the second circumferential wall portion 56b, ensuring contact pressure between each exposure-preventing cylindrical portion 108 and the second divided shell 62.

[0046] Similarly, in each exposure-preventing cylindrical portion 108, a plurality of elastic contact pieces 116 are provided below each engaging portion 110 and each locking projection 112, arranged in a cut-and-bent shape. Before the electromagnetic shielding connector 10 is connected to the mating connector 146 (described later), each of these elastic contact pieces 116 protrudes outward in the front-to-back or left-to-right direction. When the electromagnetic shielding connector 10 is connected to the mating connector 146, each elastic contact piece 116 is pressed against the inner circumferential surface of the cylindrical portion 152 of the housing 20 of the mating connector 146, and elastically deforms inward in the front-to-back or left-to-right direction. Due to the elastic restoration deformation in response to this elastic deformation, each elastic contact piece 116 is pressed against the inner circumferential surface of the cylindrical portion 152, ensuring contact pressure between each exposure-preventing cylindrical portion 108 and the housing 20. As a result, each exposure-preventing cylindrical portion 108, and by extension the shield shell 18, is electrically connected to the housing 20.

[0047] <Outer housing 28> The outer housing 28 is molded on the outside of the shield shell 18. In Embodiment 1, substantially the entire surface of the shield shell 18 except for the lower part is covered by the outer housing 28. That is, the outer housing 28 has a box-shaped portion 118 that covers the shield shell 18 from above and is open substantially downward, and a flange-shaped protrusion that protrudes from the lower opening of the box-shaped portion 118 to the outer peripheral side and is overlapped and attached to the housing 20 when connected to a mating connector 146 described later. And a mounting portion 120. Further, the outer housing 28 includes a substantially cylindrical lower protruding portion 122 that protrudes downward from the mounting portion 120. Furthermore, the outer housing 28 covers the front portion of each shielded electric wire 24 with terminals that extends rearward from the shield shell 18 in addition to the shield shell 18, and has a rear protruding portion 124 that protrudes rearward from the box-shaped portion 118 and covers the front portion of each shielded electric wire 24 with terminals. Each rear protruding portion 124 reaches the front portion of each shrink tube 40 that is externally inserted into each outer insulating coating 34.

[0048] And a collar 126 is fixed to the mounting portion 120 in a substantially embedded state, and the electromagnetic shield connector 10 is fixed to the mating connector 146 by a bolt 128 inserted through the collar 126. Further, as shown in FIG. 13, a substantially annular seal rubber 130 and a front retainer 132 are externally inserted and attached to the lower protruding portion 122, and the front retainer 132 prevents the seal rubber 130 from falling off.

[0049] In Embodiment 1, the outer housing 28 is formed as an integrally molded product (secondary molded product 134) that integrally includes the shield shell 18 (and the primary molded product 52). That is, as shown in FIGS. 10 and 11, when molding the outer housing 28, the shield shell 18 (and the front portion of the primary molded product 52) is set in the molding cavity of the outer housing 28 constituted by the mold 136. The molding cavity is constituted by upper and lower molds, but in FIGS. 10 and 11, the lower mold 136 is partially shown.

[0050] Specifically, the mold 136 is provided with an insertion portion 138 that is inserted into the shield shell 18 (second divided shell 62) from below, and this insertion portion 138 is inserted into the second circumferential wall portion 56b of the second divided shell 62. The outer circumferential surface 140 of the insertion portion 138 is a substantially rectangular cylindrical shape that corresponds to the inner circumferential surface 100 of the second circumferential wall portion 56b. Furthermore, the shield shell 18 is fixed to the insertion portion 138 by positioning pins 142 that are inserted through each pin insertion hole 94 at the lower end of the second circumferential wall portion 56b. In addition, each collar 126 is set in a predetermined position within the molding cavity of the outer housing 28. By molding the outer housing 28 in this state, an outer housing 28 (secondary molded product 134) integrally comprising the shield shell 18 (and primary molded product 52) ​​is formed, as shown in Figure 12. Therefore, in the outer housing 28 (secondary molded product 134), a mold-cut hole 144 is formed in the location where each positioning pin 142 was provided by removing each positioning pin 142.

[0051] <Mating Connector 146> The structure of the mating connector 146 to which the electromagnetic shielding connector 10 according to this disclosure is connected is not limited, but a specific example of the mating connector 146 is shown in Figures 1 and 2, etc. The mating connector 146 is a connector provided in electrical equipment such as an inverter, and since the electromagnetic shielding connector 10 of Embodiment 1 is the male connector, the mating connector 146 is the female connector. Therefore, the mating connector 146 is equipped with mating terminals (female terminals) 148 to which each terminal (male terminal) 22 of the electromagnetic shielding connector 10 is connected. As the mating terminal 148 is a female terminal, a known female terminal structure is adopted, so a description is omitted.

[0052] The housing 20, which holds the mating connector 146, has a through hole 150 that penetrates the housing 20 in the thickness direction (vertical direction), and each mating terminal 148 is exposed to the outside through the through hole 150. As a result, each terminal 22 and each mating terminal 148 can be connected by inserting the lower part of the electromagnetic shielding connector 10 through the through hole 150. The housing 20 is provided with a cylindrical portion 152 that protrudes upward from the periphery of the through hole 150. When the electromagnetic shielding connector 10 and the mating connector 146 are connected, the mounting portion 120 of the outer housing 28 is superimposed on the cylindrical portion 152 in the vertical direction, and the elastic contact pieces 116 of each exposure prevention cylindrical portion 108 come into contact with the inner circumferential surface of the cylindrical portion 152.

[0053] <Assembly of the Electromagnetic Shielding Connector 10> The following describes a specific example of how to assemble the electromagnetic shielding connector 10. However, the assembly method of the electromagnetic shielding connector 10 is not limited to the embodiments described below.

[0054] First, as shown in Figure 6, each core wire 30 is exposed at the terminal (front end) of each shielded wire 16, and each core wire 30 is fixed to the base end 42 of each terminal 22 by welding or the like. This completes each shielded wire 24 with terminals. In each shielded wire 24 with terminals, as described above, the braided wire 14 is exposed at a position separated by a predetermined distance rearward from the exposed portion of each core wire 30.

[0055] Then, with the front portions of each of these terminal-equipped shielded wires 24 set in the molding cavity of the inner housing 26, the inner housing 26 is molded to form an inner housing 26 (primary molded product 52) ​​integrally equipped with each terminal-equipped shielded wire 24, as shown in Figure 7.

[0056] Subsequently, as shown in Figure 8, each adhesive tube 38, each heat shrink tube 40, and each crimping ring 106 are fitted onto each terminal-equipped shielded wire 24, and the first divided shell 60 and the second divided shell 62 are brought close to the inner housing 26 from both the upper and lower sides. Then, the positioning parts 50 are inserted into each positioning part 74, 76, and 90, and the first divided shell 60 and the second divided shell 62 are assembled to the inner housing 26. As a result, each first flange part 78 of the first divided shell 60 and each second flange part 92 of the second divided shell 62 are superimposed in the vertical direction. In addition, the first divided sleeve 64 and the second divided sleeve 80 are inserted between the base ring 36 and the braided wire 14 in the radial direction. Then, the first divided shell 60 and the second divided shell 62 are fixed by crimping at the overlapping portion of each first flange part 78 and each second flange part 92. Furthermore, from the state shown in Figure 8, each crimping ring 106 is moved forward and the first divided sleeve 64 and the second divided sleeve 80 are crimped and fixed to form the shield sleeve 102. As a result, the shield shell 18 is assembled to the inner housing 26 (primary molded product 52), as shown in Figure 9.

[0057] Next, the insertion portion 138 is inserted from below into the shield shell 18 (and the front portion of the primary molded product 52) ​​in the state shown in Figure 9, as shown in Figures 10 and 11, and fixed with the positioning pin 142. At the same time, each collar 126 is set in the molding cavity which includes the mold 136, and the outer housing 28 is molded. This forms the outer housing 28 (secondary molded product 134) which integrally includes the shield shell 18 (and the primary molded product 52), as shown in Figure 12.

[0058] Next, as shown in Figure 13, the seal rubber 130 and the front retainer 132 are fitted onto the downward projection 122 of the outer housing 28. Then, each exposure-preventing cylindrical portion 108 is inserted from below into the lower end portion (second peripheral wall portion 56b) of the second divided shell 62, and each engaging portion 110 is fitted into each pin insertion hole 94, and each locking projection 112 is locked into each locking hole 96. In this way, each exposure-preventing cylindrical portion 108 is assembled to the shield shell 18, and the electromagnetic shield connector 10 of Embodiment 1 is completed. In the electromagnetic shield connector 10 formed in this way, the braided wire 14, the shield shell 18, and each exposure-preventing cylindrical portion 108 are electrically connected.

[0059] <Connection between electromagnetic shield connector 10 and mating connector 146> The electromagnetic shield connector 10, manufactured as described above, is inserted into the mating connector 146 from a position facing each other vertically as shown in Figure 2, with the lower part of the electromagnetic shield connector 10 inserted through the through hole 150 of the housing 20. As a result, each male terminal 22 is inserted into each female mating terminal 148, and each terminal 22 and each mating terminal 148 are electrically connected. In this way, the electromagnetic shield connector 10 and the mating connector 146 are electrically connected. Furthermore, each exposure prevention cylinder portion 108 is inserted into the cylindrical portion 152 of the housing 20, and each elastic contact piece 116 contacts the inner circumferential surface of the cylindrical portion 152, thereby electrically connecting each exposure prevention cylinder portion 108 and the housing 20. As a result, the braided wire 14 is electrically connected to the housing 20 via the shield shell 18 (conductive portion 54) and each exposure prevention cylinder portion 108, and the housing 20 is connected to earth, thereby forming an earth path (ground line) from the braided wire 14 to the housing 20. Consequently, each shield wire 16 exhibits an electromagnetic shielding effect from each shielding member (each braided wire 14).

[0060] In the electromagnetic shield connector 10 with the structure described above, the outer housing 28 is formed by mold molding with the shield shell 18 and primary molded product 52 as insert parts. When molding the outer housing 28, the insertion part 138 of the mold 136 is inserted into the shield shell 18 (second circumferential wall portion 56b) from below. Here, the circumferential wall portion 56 of the shield shell 18 (first circumferential wall portion 56a and second circumferential wall portion 56b) is provided with an expansion / contraction allowance portion 58 that allows the circumferential wall portion 56 to expand and contract. As a result, when the insertion part 138 is inserted into the second circumferential wall portion 56b, the inner circumferential surface 100 of the second circumferential wall portion 56b and the outer circumferential surface 140 of the insertion part 138 can be brought into close contact. This prevents the resin material of the outer housing 28 from seeping into the interior from between the inner surface 100 of the second peripheral wall portion 56b and the outer surface 140 of the insertion portion 138 during the molding of the outer housing 28.

[0061] In particular, before inserting the insertion portion 138 into the second circumferential wall portion 56b, the circumference of the inner circumferential surface 100 of the second circumferential wall portion 56b is made smaller than the circumference of the outer circumferential surface 140 of the insertion portion 138, so that the insertion portion 138 is inserted into the second circumferential wall portion 56b in a press-fit state. As a result, when the insertion portion 138 is inserted into the second circumferential wall portion 56b, the circumference of the inner circumferential surface 100 of the second circumferential wall portion 56b and the circumference of the outer circumferential surface 140 of the insertion portion 138 can be made equal, and a gap between these inner circumferential surface 100 and outer circumferential surface 140 can be more reliably prevented.

[0062] The expandable portion 58 includes a portion (overlapping portion 98) where the circumferential ends of the circumferential wall portion 56 (particularly the second circumferential wall portion 56b) overlap. In other words, instead of making the second circumferential wall portion 56b a continuous cylindrical shape over the entire circumference, by making both circumferential ends free ends that can be displaced from one another, a mechanism for expanding and contracting the second circumferential wall portion 56b in the circumferential direction can be realized with a simple structure.

[0063] Furthermore, the expansion / contraction allowance portion 58 includes a slit 76 that penetrates the circumferential wall portion 56 (particularly the first circumferential wall portion 56a) in the thickness direction, and in Embodiment 1, the slit 76 is provided above the overlap portion 98. In particular, in Embodiment 1, the first circumferential wall portion 56a and the second circumferential wall portion 56b are fixed to each other, and by providing a slit 76 in the first circumferential wall portion 56a, the first circumferential wall portion 56a can be expanded and contracted in the circumferential direction in accordance with the expansion and contraction of the second circumferential wall portion 56b in the circumferential direction. As a result, even if the second circumferential wall portion 56b deforms to expand relatively large in the circumferential direction due to the insertion portion 138, for example, the first circumferential wall portion 56a expands in the circumferential direction in accordance with this deformation, thereby preventing a gap from forming between the first circumferential wall portion 56a and the second circumferential wall portion 56b. Therefore, it is possible to prevent the resin material of the outer housing 28 from penetrating into the interior through the gap between the first peripheral wall portion 56a and the second peripheral wall portion 56b.

[0064] <Modifications> Although Embodiment 1 has been described in detail above as a specific example of the present disclosure, the present disclosure is not limited by this specific description. Modifications, improvements, etc., to the extent that they can achieve the purpose of the present disclosure are included in the present disclosure. For example, the following modifications of the embodiments are also included in the technical scope of the present disclosure.

[0065] (1) In the above embodiment, each terminal 22 was shaped to extend in a substantially straight line and protruded in a direction perpendicular to the extension direction (front-to-back direction) of each shield wire 16 (downward). However, for example, the terminal may be L-shaped, and the tip of the terminal may protrude in a direction perpendicular to the extension direction of the shield wire, similar to the above embodiment.

[0066] (2) In the above embodiment, the first divided shell 60 and the second divided shell 62 were fixed together by crimping, but the first divided shell and the second divided shell may be fixed together by known fixing methods such as welding or bolting. Similarly, in the above embodiment, the first divided sleeve 64 and the second divided sleeve 80 were fixed together by crimping rings 106, but the first divided sleeve and the second divided sleeve may be fixed together by known fixing methods such as welding or bolting.

[0067] (3) In the above embodiment, the second divided shell 62 and each exposure prevention cylinder portion 108 were fixed using the pin insertion holes 94 used when forming the outer housing 28. However, the embodiment is not limited to this, and the second divided shell and each exposure prevention cylinder portion may be fixed by a different fixing method than in the above embodiment. The second divided shell and each exposure prevention cylinder portion do not need to be formed as separate parts, and the second divided shell may be formed to a length that covers the tip of each terminal.

[0068] (4) In the above embodiment, the shield sleeve 102, which consists of a first divided sleeve 64 and a second divided sleeve 80, was shaped to have a substantially cylindrical portion on both the left and right sides. However, the shield sleeve may also be shaped to have a substantially oval portion that covers both the left and right braided wires, in which case the crimping ring may also be a corresponding substantially oval shape. In addition, in the above embodiment, a pair of exposure-preventing cylindrical portions 108, 108 were provided to cover the respective tip portions 44 of each terminal 22. However, a single rectangular cylindrical exposure-preventing cylindrical portion with the left-right direction as the longitudinal direction may also be provided.

[0069] (5) In the above embodiment, before the insertion portion 138 of the mold 136 was inserted into the second circumferential wall portion 56b, the circumference of the inner circumferential surface 100 of the second circumferential wall portion 56b was smaller than the circumference of the outer circumferential surface 140 of the insertion portion 138. However, the embodiment is not limited to this. For example, before the insertion portion of the mold is inserted into the circumferential wall portion of the shield shell, the circumference of the inner circumferential surface of the circumferential wall portion may be slightly larger than the circumference of the outer circumferential surface of the insertion portion. That is, by providing an expansion / contraction allowance portion in the circumferential wall portion, the circumferential wall portion can be expanded and contracted relatively easily in the circumferential direction. Therefore, even if the circumference of the inner circumferential surface of the circumferential wall portion is slightly larger than the circumference of the outer circumferential surface of the insertion portion, the circumferential wall portion can be reduced in the circumferential direction by resin pressure during molding of the outer housing, for example, and the inner circumferential surface of the circumferential wall portion and the outer circumferential surface of the insertion portion can be brought into close contact.

[0070] (6) In the above embodiment, expansion / contraction allowances 58 (slits 76 and overlapping portions 98) were provided in the front wall portions (first front wall portion 68 and second front wall portion 82) of the peripheral wall portion 56 of the shield shell 18, but the embodiment is not limited to this. The expansion / contraction allowances only need to be provided in at least a part of the circumference of the peripheral wall portion of the shield shell, and may be provided in the wall portion in at least one direction, such as the rear, left, or right, instead of or in addition to the front wall portion.
