Description

Connector

[0001] The present disclosure relates to a connector.

[0002] Patent Document 1 discloses a shielded connector in which a metal shield shell is mounted around an inner housing that accommodates a terminal fitting connected to an end of an electric wire, and an outer housing is assembled around the shield shell. A predetermined gap for accommodating the shield shell is secured between the opposing surfaces of the inner housing and the outer housing, and the shield shell is fixedly held between the inner housing and the outer housing.

[0003] Japanese Unexamined Patent Publication No. 2024-153244

[0004] However, in the structure of Patent Document 1, a gap for accommodating the shield shell is formed between the inner housing and the outer housing. Therefore, if a connector that does not require a shielding function is needed, even if an attempt is made to remove the shield shell for use, the gap causes rattling between the inner housing and the outer housing, making assembly itself difficult. Therefore, it was necessary to separately design a dedicated connector that does not include a shield shell.

[0005] Accordingly, the present disclosure discloses a highly versatile connector that can be used regardless of whether a shield shell is provided or not.

[0006] The connector of the present disclosure comprises: an inner housing that accommodates a terminal fitting connected to an end of an electric wire; an outer housing mounted to surround the inner housing; a shield shell accommodation space provided between opposing surfaces of the inner housing and the outer housing; a plurality of positioning protrusions that protrude from at least one of the inner housing and the outer housing toward the other and abut against the other to maintain the shield shell accommodation space and position the inner housing and the outer housing relative to each other; and a shield shell that is selectively mountable to the shield shell accommodation space and has a plurality of protrusion through-holes through which the positioning protrusions penetrate.

[0007] The connector of this disclosure can be used with or without a shield shell, thereby improving versatility.

[0009] <Description of Embodiments of the Disclosure> First, embodiments of the Disclosure will be listed and described. The connector of the Disclosure comprises: (1) an inner housing housing terminal fittings connected to the end of an electric wire; an outer housing mounted surrounding the inner housing; a shield shell housing space provided between the opposing surfaces of the inner housing and the outer housing; a plurality of positioning protrusions projecting from at least one of the inner housing and the outer housing toward the other, and abutting against the other to hold the shield shell housing space and position the inner housing and the outer housing toward each other; and a shield shell that can be selectively mounted on the shield shell housing space and has a plurality of through-holes through which the positioning protrusions pass.

[0010] According to the connector of this disclosure, a shield shell housing space is secured between the opposing surfaces of the inner housing and the outer housing. This shield shell housing space is held in place by a plurality of positioning protrusions that project from at least one of the inner housing and the outer housing toward the other, and which abut against the other. That is, the positioning protrusions projecting from at least one of the inner housing and the outer housing abut against the other, so that the inner housing and the outer housing are positioned relative to each other while securing the shield shell housing space between their opposing surfaces. Furthermore, the shield shell, which can be selectively mounted in the shield shell housing space, is provided with a plurality of through-holes through which the plurality of positioning protrusions each pass. As a result, whether the shield shell is mounted in the shield shell housing space (Usage Mode 1) or not mounted in the shield shell housing space (Usage Mode 2), the inner housing and the outer housing can be positioned relative to each other while securing the shield shell housing space between their opposing surfaces, thereby preventing or suppressing rattling between the inner housing and the outer housing and enabling assembly of them. As a result, it is possible to selectively install a shield shell into the shield shell housing space, providing a highly versatile connector that can be used with or without a shield shell.

[0011] (2) In the above (1), it is preferable that the inner housing has an inner top wall that covers the tip side of the terminal fitting and an inner peripheral wall that covers the periphery of the terminal fitting, the outer housing has an outer top wall that faces the inner top wall from the outside and an outer peripheral wall that faces the inner peripheral wall from the outside, a press-fit projection that protrudes from the inner top wall is press-fitted into a press-fit recess provided in the outer top wall and fixed, the inner peripheral wall has a tip that connects to the inner top wall and a base that is separated from the inner top wall, and a plurality of positioning projections protrude toward the outer peripheral wall at a portion of the base of the inner peripheral wall that is separated from each other in the circumferential direction. A press-fit projection is provided on the inner top wall that is the tip side when assembling the inner housing to the outer housing, and is press-fitted into a press-fit recess provided in the outer top wall and fixed. As a result, during the assembly of the inner and outer housings, the press-fitting projections can be pressed into the press-fitting recesses to hold both in the assembled state, thereby improving the efficiency of the assembly process. Furthermore, as a result of pressing the press-fitting projections into the press-fitting recesses, multiple positioning projections, which are dispersed in the circumferential direction of the inner peripheral wall, protrude toward the outer peripheral wall. This ensures that the outer housing is stably positioned in the circumferential direction of the inner housing, and that a stable space for housing the shield shell can be secured between them.

[0012] (3) In (1) or (2) above, it is preferable that the shield shell is mounted in the shield shell housing space and that the multiple positioning protrusions each pass through the multiple protrusion through holes. When a shielding function is required, the connector can be provided with a shielding function simply by mounting the shield shell in the shield shell housing space. Moreover, by utilizing the fact that the positioning protrusions are inserted through the multiple protrusion through holes of the shield shell, the shield shell can be reliably positioned and fixed to the inner housing.

[0013] (4) In (1) or (2) above, it is preferable that the shield shell is not installed in the shield shell housing space. If a shielding function is not required, the connector can be provided as one without a shielding function simply by not installing the shield shell in the shield shell housing space. Moreover, since the positioning projections protruding from at least one of the inner housing and the outer housing abut against the other, the inner housing and the outer housing can be prevented from rattling and positioned relative to each other, thus preventing the assembly from becoming difficult as in conventional structures, and providing a highly versatile connector.

[0014] <Details of Embodiments of the Disclosure> Specific examples of the connectors of the Disclosure are 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, the connector 10 of Embodiment 1 of the present disclosure will be described with reference to Figures 1 to 8. The connector 10 is provided at the end of an electric wire connected to in-vehicle equipment installed in a vehicle such as an electric vehicle or a hybrid vehicle. The connector 10 can be positioned in any orientation within the vehicle, but in the following description, unless otherwise specified, the directions indicated by the arrows in Figure 1 will be described as the up-down direction, the front-back direction, and the left-right direction. In addition, for multiple identical components, reference numerals may be assigned to only some of the components, while the reference numerals for other components may be omitted.

[0016] <Connector 10> The connector 10 comprises an inner housing 16 that houses terminal fittings 14 connected to the end of the electric wire 12, and an outer housing 18 that surrounds and is mounted on the inner housing 16. Furthermore, a shield shell 22 can be selectively mounted in a shield shell housing space 20 provided between the opposing surfaces of the inner housing 16 and the outer housing 18. When a shielding function is required for the connector 10, there is a usage mode 1 (Figures 1-6) in which the shield shell 22 is mounted in the shield shell housing space 20, and when a shielding function is not required for the connector 10, there is a usage mode 2 (Figures 7-8) in which the shield shell 22 is not mounted in the shield shell housing space 20. In the following description, usage mode 1 will be explained first based on Figures 1-6, and then usage mode 2 will be explained based on Figures 7-8.

[0017] <Electric Wire 12, Terminal Fitting 14> The electric wire 12 has a core wire 24 exposed at its end, and the core wire 24 exposed at the end is fixed to the base end of the terminal fitting 14. The terminal fitting 14 is made of copper, aluminum, or an alloy thereof, and its tip is electrically connected to the mating terminal fitting of a mating connector (not shown). In Embodiment 1, a pair of terminal fittings 14 and the electric wire 12 extending from them are each housed in a pair of inner housings 16.

[0018] <Inner Housing 16> The inner housing 16 is made of an insulating material such as synthetic resin and is configured as a rectangular box that opens downwards. The inner housing 16 is provided with a cylindrical terminal housing portion 26 that extends vertically through the inside of the inner housing 16 (see Figure 5). The upper end of the terminal housing portion 26, which is one end, is exposed to the outside through an inner opening 28 that opens on one side of the inner housing 16 (the front surface in Figure 1). The lower end of the terminal housing portion 26, which is the other end, is exposed to the outside through a wire insertion hole 30 that opens on the bottom surface of the inner housing 16 (the lower surface in Figure 1). The electric wire 12, which is fixed to the terminal fitting 14, is pulled out to the outside of the inner housing 16 by passing through the wire insertion hole 30.

[0019] The inner housing 16 has an inner top wall that covers the tip side (upper end side in Figure 2) of the terminal fitting 14 and an inner peripheral wall 34 that covers the periphery of the terminal fitting. As shown in Figure 2, the inner opening 28 is provided in a portion of the inner peripheral wall 34 that is located on the front side. The inner peripheral wall 34 has a tip portion (upper side in Figure 2) that connects to the inner top wall 32 and a base portion (lower side in Figure 1) that is separated from the inner top wall 32. Multiple positioning protrusions 36 are provided at portions of the base portion of the inner peripheral wall 34 that are separated from each other in the circumferential direction, and project toward the outer peripheral wall. As clearly shown in Figures 2 and 3, in the embodiment 1, two positioning protrusions 36 are provided on each of the inner peripheral wall 34 at opposing portions in the front-rear direction, and one positioning protrusion 36 is provided on each of the inner peripheral wall 34 at opposing portions in the left-right direction. A press-fit projection 38 is provided in the central part of the inner top wall 32, projecting upward. The press-fit projection 38 has a roughly circular cross-section and protrudes upward, and multiple seal ribs extending in the axial direction are provided on its outer surface.

[0020] <Shield Shell 22> The shield shell 22 is formed by press-punching a metal plate such as aluminum or an aluminum alloy, and includes a shell top wall 40 and a shell periphery wall 42 that are superimposed and mounted on the inner top wall 32 and inner periphery wall 34 of the inner housing 16. The shield shell 22 as a whole is configured in the shape of a rectangular box that opens downwards, similar to the inner housing 16. A projection insertion hole 44 is provided through the central part of the shell top wall 40. At the upper end of the shell periphery wall 42, a shell opening 46 is provided that opens to one side of the shell periphery wall 42 (the front surface in Figure 1), and the inner opening 28 of the inner housing 16 is exposed to the outside through the shell opening 46. At the lower end of the shell periphery wall 42, an inner insertion opening 48 is provided that opens to the bottom surface of the shield shell 22 (the lower surface in Figure 1) to allow insertion of the inner housing 16.

[0021] At the lower end of the shell peripheral wall 42, multiple through-holes 50 are provided at positions that are spaced apart from each other in the circumferential direction and correspond to multiple positioning protrusions 36 provided on the inner housing 16. Furthermore, at opposing portions of the shell peripheral wall 42 in the left-right direction, two pressing pieces 52 are provided in a cut-out and bent shape, each projecting inclined inward in the opposing direction.

[0022] <Terminal Assembly 54> Figure 4 shows a terminal assembly 54 having the structure described above, in which a terminal fitting 14 connected to the end of the electric wire 12, an inner housing 16, and a shield shell 22 are assembled together. To assemble the terminal assembly 54, first prepare an electric wire 12 with a terminal fitting 14 attached, to which the core wire 24 of the electric wire 12 is connected to the base end of the terminal fitting 14. Insert the terminal fitting 14 from the tip side of the terminal fitting 14 through the wire insertion hole 30 of the inner housing 16 and attach the terminal fitting 14 to the terminal housing portion 26 of the inner housing. Then, insert the inner housing 16 into the inside of the shield shell 22 by inserting it from the inner top wall 32 side of the inner housing 16 through the inner insertion opening 48 of the shield shell 22 and assemble it. Finally, the press-fit projection 38 of the inner housing 16 is inserted through the projection insertion hole 44 of the shield shell 22, and the shell top wall 40 overlaps the inner top wall 32. Furthermore, the positioning projection 36 of the inner housing 16 is positioned to pass through the projection through-hole 50 of the shield shell 22, and the shell peripheral wall 42 overlaps the inner peripheral wall 34. At this time, the pressing piece 52 provided on the shield shell 22 is pressed against the inner peripheral wall 34 of the inner housing 16 from both the left and right sides, so that the shield shell 22 is positioned in a centered state relative to the inner housing 16 and assembled with high precision.

[0023] <Outer Housing 18> The outer housing 18 is made of an insulating material such as synthetic resin and is configured as a rectangular box. The outer housing 18 is provided with a pair of cylindrical assembly housing sections 56 that extend vertically through the inside of the outer housing 18 (see Figure 5). The upper end of each assembly housing section 56 is exposed to the outside through an outer opening 58 that opens on one side of the outer housing 18 (the front surface in Figure 1). The lower end of each assembly housing section 56 is exposed to the outside through a pair of wire outlets 60 that open on the bottom surface of the outer housing 18 (the lower surface in Figure 1). The wires 12 fixed to the terminal fittings 14 of the terminal assembly 54 are pulled out to the outside of the outer housing 18 by passing through each wire outlet 60.

[0024] As shown in the cross-sectional view of Figure 5, the outer housing 18 has an outer top wall 62 that faces the inner top wall 32 of the inner housing 16 from the outside, and an outer peripheral wall 64 that faces the inner peripheral wall 34 of the inner housing 16 from the outside. On the outer top wall 62, press-fit recesses 66 are provided that open downwards at positions corresponding to the front end faces of each assembly housing section 56, into which press-fit projections 38 protruding from the inner top wall 32 are press-fitted and fixed. When the terminal assembly 54 is inserted into each assembly housing section 56 of the outer housing 18 from the wire outlet 60 side and assembled from the shell top wall 40 side of the shield shell 22, the press-fit projections 38 of the inner housing 16 are press-fitted into the press-fit recesses 66 of the outer housing 18, thereby fixing the inner housing 16 to the outer housing 18. Although not shown in the diagram, the outer housing 18 is equipped with a sealing rubber or back retainer, which allows the electric wire 12 to pass through and seal the electric wire outlet 60. With the outer housing 18 mounted surrounding the inner housing 16 in this manner, a shield shell housing space 20 is provided between the opposing surfaces of the inner housing 16 and the outer housing 18 (see Figures 5 to 8). This shield shell housing space 20 is securely held in place by the protruding tips of the positioning protrusions 36 provided on the inner housing 16 contacting the inner circumferential surface of the assembly housing portion 56 of the outer housing 18. The protruding tips of each positioning protrusion 36 are positioned to pass through projection through holes 50 provided on the shield shell 22. Therefore, regardless of the presence or absence of the shield shell 22, the protruding tip of each positioning projection 36 abuts against the inner circumferential surface of the assembly housing portion 56 of the outer housing 18, thereby enabling the inner housing 16 and the outer housing 18 to be assembled in a relative position while maintaining the shield shell housing space 20. In the cross-sectional view of Figure 5, four positioning projections 36 are shown on both the left and right sides of the inner housing 16, but in the cross-sectional view of Figure 6, only the positioning projection 36 on the front side is shown.The positioning projection 36 provided on the rear side of the inner housing 16 is located further back than the cross-section shown in Figure 6, and is positioned to contact the inner circumferential surface of the assembly housing portion 56 of the outer housing 18.

[0025] <Assembly of Connector 10> Next, an example of how to assemble the connector 10 configured as described above will be given. When assembling the connector 10, first, a terminal fitting 14 is prepared by pressing a metal plate and attaching the core wire 24 of the electric wire 12 to the base end of the terminal fitting 14. Furthermore, an inner housing 16 and an outer housing 18 of the shape described above are prepared by injection molding or the like. Furthermore, a shield shell 22 of the configuration described above is prepared by pressing a metal plate. Subsequently, a terminal assembly 54 is prepared by assembling the shield shell 22 into the inner housing 16 that houses the terminal fitting 14 using the process described above. Subsequently, as shown in Figure 5, the terminal assembly 54 is inserted into each assembly housing section 56 of the outer housing 18 from the electric wire outlet 60 side and into the top wall 40 side of the shield shell 22. Finally, the press-fit projection 38 of the inner housing 16 is press-fitted into the press-fit recess 66 of the outer housing 18, thereby permanently assembling the inner housing 16 to the outer housing 18. In this state, the wires 12 of the terminal assembly 54 are pulled out from each wire outlet 60 of the outer housing 18. In this way, the assembly of the connector 10 is completed, and the connector 10 of Embodiment 1 is finished.

[0026] <Usage Mode 1 of Connector 10> One of the features of the connector 10 of Embodiment 1 is that it can be used with or without the presence of a shield shell 22. Figures 1 to 6 show Usage Mode 1, in which the connector is used with the shield shell 22 housed in the shield shell housing space 20. In this Usage Mode 1, the shield shell 22 is held in the shield shell housing space 20, which is secured by the positioning projection 36 of the inner housing 16 contacting the inner circumferential surface of the assembly housing portion 56 of the outer housing 18, and the connector 10 can be provided with a shielding function. Moreover, by utilizing the fact that the positioning projections 36 are inserted through multiple projection through holes 50 of the shield shell 22, the shield shell 22 can be reliably positioned and fixed to the inner housing 16.

[0027] <Usage Mode 2 of Connector 10> Figures 7 and 8 show Usage Mode 2 of the connector 10 of Embodiment 1, in which the shield shell 22 is not used and the shield shell housing space 20 is left empty. In this Usage Mode 2, the shield shell housing space 20, which is secured by the positioning projection 36 of the inner housing 16 contacting the inner circumferential surface of the assembly housing portion 56 of the outer housing 18, is used in an empty state without the shield shell 22 being placed in it, and a connector 10 can be provided that does not require a shielding function. Since the positioning projection 36 protruding from the inner housing 16 contacts the outer housing 18, the inner housing 16 and the outer housing 18 can be positioned relative to each other while preventing rattling, thus preventing the difficulty of assembly that occurs in conventional structures, and a highly versatile connector 10 can be provided. Furthermore, the connector 10 in usage mode 2 can be assembled in the same way as the connector 10 in usage mode 1 by assembling the terminal assembly 54, which has been prepared without assembling the shield shell 22 to the inner housing 16, into the assembly housing section 56 of the outer housing 18.

[0028] In the connector 10 of Embodiment 1, which has the structure described above, a shield shell housing space 20 is secured between the opposing surfaces of the inner housing 16 and the outer housing 18. This shield shell housing space 20 is held in place by a plurality of positioning protrusions 36, which are provided to protrude from the inner housing 16 toward the outer housing 18, contacting the outer housing 18. That is, the positioning protrusions 36 protruding from the inner housing 16 contact the outer housing 18, so that the inner housing 16 and the outer housing 18 are positioned relative to each other while securing the shield shell housing space 20 between their opposing surfaces. Furthermore, the shield shell 22, which can be selectively mounted in the shield shell housing space 20, is provided with a plurality of projection through-holes 50 through which the plurality of positioning protrusions 36 each pass. As a result, whether the shield shell 22 is mounted in the shield shell housing space 20 (Usage Mode 1) or not mounted in the shield shell housing space 20 (Usage Mode 2), the inner housing 16 and outer housing 18 can be positioned relative to each other while ensuring the shield shell housing space 20 is secured between the opposing surfaces of the inner housing 16 and outer housing 18. This prevents or suppresses rattling between the inner housing 16 and outer housing 18, enabling assembly of the two. Consequently, the shield shell 22 can be selectively mounted in the shield shell housing space 20, and a highly versatile connector 10 can be provided that can be used with or without the shield shell 22.

[0029] When assembling the inner housing 16 to the outer housing 18, a press-fit projection 38 is provided on the inner top wall 32, which is the leading edge, and is pressed into a press-fit recess 66 provided on the outer top wall 62 to secure it. This allows the inner housing 16 and outer housing 18 to be held in the assembled state by pressing the press-fit projection 38 into the press-fit recess 66, thereby improving the efficiency of assembly. As a result of pressing the press-fit projection 38 into the press-fit recess 66, the multiple positioning projections 36, which are dispersed in the circumferential direction of the inner peripheral wall 34, protrude toward the outer peripheral wall 64. This ensures that the outer housing 18 is stably positioned in the circumferential direction of the inner housing 16, and that the shield shell housing space 20 is stably secured between them.

[0030] <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.

[0031] (1) In Embodiment 1, the positioning projection 36 provided on the inner housing 16 protruded toward the outer housing 18, but is not limited to this. For example, the positioning projection 36 may protrude from the outer housing 18 toward the inner housing 16, or a combination of a positioning projection 36 protruding from the inner housing 16 and a positioning projection 36 protruding from the outer housing 18 may be used.

[0032] (2) In Embodiment 1, an example was shown in which a pair of terminal assemblies 54 are housed in a pair of assembly housing sections 56 provided in the outer housing 18. However, the number and shape of the terminal assemblies 54, the shape of the outer housing 18 including the wire outlet 60, etc. can be arbitrarily set. For example, multiple terminal assemblies 54 may be housed in a single assembly housing section 56.

[0033] (3) The shape, number, and placement of the positioning protrusions 36 can be arbitrarily set as long as they can stably hold the shield shell housing space 20 between the opposing surfaces of the inner housing 16 and the outer housing 18.

[0034] (4) The shape, quantity, and placement of the electric wire 12, terminal fittings 14, inner housing 16, outer housing 18, and shield shell 22 can be arbitrarily set, and even if they differ, it is natural that the same effect can be obtained by applying the configuration of the disclosure.
