[0002] Conventionally, some connectors include a housing that holds a shielded cable while it is partially inserted, and are configured such that a core of the shielded cable is electrically connected to a terminal of a mating connector by connecting the housing to a mating connector (see, for example, Publication JP 2018-55833 A). In this connector, the housing has a two-layer structure comprising an inner housing and an outer housing, and in particular a multi-layer structure in which a shielding shell is arranged outside the inner housing, and the outer housing is further arranged outside the shielding shell, and the emission of electromagnetic waves (noise) from the connector is suppressed by the shielding shell or casing.

[Embodiments of the invention][Description of embodiments of the present disclosure]

[0007] First, embodiments of the present disclosure are listed and described.

[0008] [1] The coupling structure of the present disclosure comprises a connector and a mating connector fixed to a conductive sheath. The connector includes a plurality of shielded cables, each having a conductive core and a conductive shielding element; a housing made of a resin, wherein the plurality of shielded cables are held in the housing while partially inserted; a shielding terminal provided between the plurality of shielded cables in the housing and connected to the shielding elements of the plurality of shielded cables; and an electromagnetic shielding shell for covering an outer surface of the housing. The mating connector includes a grounding terminal to be conductive to the conductive sheath and a plurality of non-grounding terminals.The cores of the majority of shielded cables of the connector are each connected to the majority of non-ground terminals of the mating connector, and the shield terminal of the connector is connected to the ground terminal of the mating connector when the connector housing is mated to the mating connector. The electromagnetic shielding shell of the connector is configured to directly contact and be conductive to an outer surface of the conductive sheath when the connector housing is mated to the mating connector. The ground terminal includes folded grounding pieces in a lower end portion, with the grounding pieces positioned in a fixing hole of the conductive sheath and pressed into contact with a hole surface of the fixing hole when the mating connector is fixed to the conductive sheath.

[0009] Since the electromagnetic shielding shell is designed to cover the outer surface of the housing, the emission or radiation of electromagnetic waves from the connector can be suppressed. Furthermore, because a shielding connection is provided, which is connected to the shielding elements of the shielded cables and to the grounding terminal of the matching connector by connecting the housing to the matching connector, the shielding elements of the shielded cables can be easily connected to the grounding terminal to suppress the emission of electromagnetic waves from the shielded cables.In this way, due to the fact that the shield connection is provided between the majority of shielded cables in the housing, a configuration can be simplified and a size reduction can be achieved, for example, compared to a multi-layered structure in which a shielding shell is arranged outside an inner housing and an outer housing is further arranged outside the shielding shell as before.

[0010] [2] Preferably the electromagnetic shielding shell is configured to electrically contact the conductive sheathing at three or more points.

[0011] According to this configuration, since the electromagnetic shielding shell is set to electrically contact the conductive sheath at three or more points, the emission of electromagnetic waves can be satisfactorily suppressed.

[0012] [3] Preferably the electromagnetic shielding shell includes a grounding projection which extends to contact the conductive sheath.

[0013] According to this configuration, since the electromagnetic shielding shell includes the grounding protrusion that extends to contact the conductive sheath, the electromagnetic shielding shell can be brought into contact with the conductive sheath at an effective position while maintaining a simple configuration. That is, the electromagnetic shielding shell can be raised due to component accuracy or similar factors and may not necessarily make contact at an effective position, even if an attempt is made to bring the electromagnetic shielding shell into surface contact with the conductive sheath over a wide area. However, by avoiding this circumstance, the electromagnetic shielding shell can be brought into contact with the conductive sheath at the effective position.

[0014] [4] Preferably the electromagnetic shielding shell is configured to electrically contact the conductive sheathing at least at three points by means of a pair of grounding projections and a screw which engages the conductive sheathing through the electromagnetic shielding shell in a threaded manner.

[0015] According to this configuration, since the electromagnetic shielding shell is designed to electrically contact the conductive sheath at least at three points through the pair of grounding protrusions and the screw which is threaded into the conductive sheath by the electromagnetic shielding shell, the electromagnetic shielding shell can be stably fixed to the conductive sheath by being electrically contacted with the conductive sheath at three effective points, while having a simple configuration.

[0016] [5] Preferably, the shielding connection is made from a bent conductive or conductive plate material and includes a pair of parallel sections, a coupling section which couples first ends of the pair of parallel sections, and connecting sections which are each provided at second ends of the pair of parallel sections to be connected to the shielding elements, and the grounding connection is inserted between the pair of parallel sections and is connected to the pair of parallel sections when the housing is connected with the matching connector.

[0017] According to this configuration, since the shield connection is made from the bent conductive sheet material, the shield connection can be easily manufactured. Furthermore, since the ground connection is inserted between the pair of parallel sections and connected to the pair of parallel sections when the housing is connected with the matching connector, the shield connection and the ground connection can be connected with high reliability, for example, compared to the case where the shield connection and the ground connection are only connected by a contact piece configured to make contact in a single direction. [Details of the embodiment of the present disclosure]

[0018] A specific example of a connector of the present disclosure is described below with reference to the drawings. It should be noted that the present invention is not limited to these illustrations and is intended to be represented by claims, including all modifications in the scope of claims and in the meaning and scope of equivalents.

[0019] As this is in Fig. Figure 1 shows a connector 11 fixed to a part of a casing 12 of an electrical device, such as an inverter, which is to be installed in a vehicle.

[0020] In particular, how this is done in Fig. 2, Fig. 4 and Fig. As shown in Figure 5, connector 11 is connected to a matching connector 13 and fixed to it in a vertical direction. The connector 13 is fixed to the sheath 12, which serves as a conductive element, by screws N. The sheath 12 is made of a metal material, and the matching connector 13 is made of a resin or plastic material. It should be noted that in this embodiment, the sheath 12 and the matching connector 13 form a matching element. In this example, the vertical direction can be referred to as the mounting direction of connector 11 and the matching connector 13.

[0021] As this is in Fig. As shown in Figure 2, the mating connector 13 is provided with a pair of terminals 13a, which project upwards in the vertical direction. The terminals 13a are non-grounding terminals and can, for example, be current or power terminals. Furthermore, the mating connector 13 is provided with a grounding terminal 13b, which projects upwards in the vertical direction between the pair of terminals 13a. The grounding terminal 13b is made of a conductive plate material, such as a bent metal plate. The mating connector 13 includes a support column 13c for supporting the grounding terminal 13b. The support column 13c is arranged, for example, between the pair of terminals 13a. The grounding terminal 13b is designed to cover surfaces of the support column 13c that face the terminals 13a.The grounding connection 13b includes folded grounding pieces 13d in a lower end section. As shown in . Fig. As shown in Figure 4, the grounding pieces 13d are arranged in a fixing hole 12a of the casing 12 and are pressed or pushed into contact with a hole surface of the fixing hole 12a when the matching connector 13 is fixed to the casing 12.

[0022] As this is in Fig. As shown in Figures 2 to 4, the connector 11 includes a housing 21 and an electromagnetic shielding shell 22 for covering the outer surface of the housing 21. A pair of shielded cables 14 is partially inserted into and held within the housing 21. The housing 21 is made of a resin or plastic material, and the electromagnetic shielding shell 22 is made of a metal material.

[0023] The housing 21 comprises a body section 21a, which has an opening in its lower part, and a wire insertion section 21b, which extends orthogonally to the vertical direction from the body section 21a in one direction (wire extraction direction). The wire insertion section 21b is essentially in the form of a rectangular or right-angled tube and is open orthogonally to the vertical direction (wire extraction direction), and the terminal parts of the pair of shielded cables 14 are held in place therein. The wire insertion section 21b is provided with a rubber seal 23, which is to be inserted between the inner surface of the wire insertion section 21b and the outer surfaces of the shielded cables 14, and with a retaining device 24 for restricting the protrusion of the rubber seal 23 from the wire insertion section 21b by being fixed to the wire insertion section 21b.is inserted between the inner surface of the wire insertion section 21b and the outer surfaces of the shielded cables 14.

[0024] The electromagnetic shielding shell 22 is shaped to cover the outer surface of the housing 21, with the exception of the lower surface of the housing 21 and parts corresponding to the shielded cables 14, which are to be inserted into the wire insertion section 21b. The electromagnetic shielding shell 22 is assembled with the housing 21 from above and locked to it. In particular, as shown in Fig. Figure 2 shows that the electromagnetic shielding shell 22 is locked to the housing 21 by locking claws 21c, which are formed on the housing 21 and which are locked in locking holes 22a, which are formed in the electromagnetic shielding shell 22.

[0025] As this is in Fig. As shown in Figure 3, each shielded cable 14 comprises a core 14a, such as a conductive metal wire, an inner insulating layer 14b for covering the outer circumference of the core 14a, a shielding element 14c for covering the outer circumference of the inner insulating layer 14b, and an outer insulating layer 14d for covering the outer circumference of the shielding element 14c. The shielding element 14c is, for example, a stranded wire formed by braiding or stranding conductive strands of an aluminum alloy or the like into a tubular shape and is flexible. A socket terminal 25 is fixed to a tip portion of the core 14a, which is exposed on the outside. The socket terminal 25 is positioned to be electrically connected to the terminal 13a of the mating connector 13.to be, which is inserted therein when the housing 21 is connected to the matching connector 13. A lower housing 26, which is to be fitted onto a part of the matching connector 13, while the exit of the shielded cables 14, which contain the socket terminals 25, is restricted by being engaged with the socket terminals 25, is fixed or is fixed at the lower opening in the body section 21a of the housing 21.

[0026] Furthermore, it includes how this is in Fig. 2 and Fig. As shown in Figure 3, the connector 11 has a shielding terminal 27, which is provided between the pair of shielded cables 14 in the housing 21 and is held in contact with the shielding elements 14c of the pair of shielded cables 14. The shielding terminal 27 of the connector 11 is connected to the grounding terminal 13b by connecting the housing 21 to the matching connector 13. In this way, the shielding elements 14c of the shielded cables 14 are made conductive to the sheath 12 via the shielding terminal 27 of the connector 11 and the grounding terminal 13b of the matching connector 13 (grounded to it).

[0027] In particular, as can be seen in Fig. As shown in Figure 6, the shielding connection 27 is a single curved conductive plate element and includes, for example, a pair of parallel sections 27a, a coupling section 27b which couples the first ends of the pair of parallel sections 27a, and connecting sections 27c which are provided at the second ends of the pair of parallel sections 27a. The connecting sections 27c are connected to the shielding elements 14c via tubular shielding sleeves or bushings 28. That is, the connecting section 27c is designed to surround the outer surface of the shielding sleeve 28 and includes a contact piece 27d to be pressed into contact with the outer surface of the shielding sleeve 28. As shown in Fig. As shown in Figure 3, the shielding element 14c is folded outwards from the outer insulating coating 14d and connected to the inner surface of the shielding sleeve 28. In this way, the connecting section 27c is electrically connected to the shielding element 14c.

[0028] The shield terminal 27 is configured such that the ground terminal 13b of the matching connector 13 is connected to the pair of parallel sections 27a when the housing 21 is connected to the matching connector 13. As shown in Fig. As shown in Figure 6, the pair of parallel sections 27a is provided with contact pieces 27e, which project towards each other, and the contact pieces 27e are pressed into contact with the grounding terminal 13b when the housing 21 is connected to the matching connector 13. A gap between the parallel sections 27a of the shielding terminal 27 is maintained by a retaining element 29, which is interposed between the inner surface of the wire insertion section 21b and the outer surface of the shielded cables 14.

[0029] The electromagnetic shielding shell 22 is configured to electrically contact the sheathing 12 at three or more points.

[0030] In particular, this includes how it is done in Fig. As shown in Figures 3 to 5, the electromagnetic shielding shell 22 has grounding projections 22b which protrude to contact the sheath 12. A pair of grounding projections 22b is provided at both ends on one side corresponding to an end portion of the wire insertion section 21b where the shielded cables 14 are exposed to the outside. The electromagnetic shielding shell 22 electrically contacts the sheath 12 at three points by means of the pair of grounding projections 22b and a screw 30 (see Figure 3). Fig. 1 and Fig. 4), which is screwable or threaded to the casing 12 through a screw passage hole 22c in the electromagnetic shielding shell 22. The screw passage hole 22c is located in a center on one side opposite the pair of grounding projections 22b. A cap 31 is placed on a head part of the screw 30.

[0031] Next, the functions of connector 11, which is configured as described above, will be described.

[0032] When the connector 11 is fixed or secured to the sheath 12, the outer surface of the housing 21 is surrounded by the electromagnetic shielding shell 22 and the sheath 12, which is a conductive element. Furthermore, the shielding elements 14c of the shielded cables 14 are connected to the sheath 12 via the shielding sleeves 28, the shielding terminal 27, and the grounding terminal 13b. In this way, the emission of electromagnetic waves from the connector 11 and the shielded cables 14 is suppressed.

[0033] The effects of the above embodiment are described below.

[0034] (1) Since the connector 11 includes the electromagnetic shielding shell 22 for covering the outer surface of the housing 21, the emission of electromagnetic waves from the connector 11 can be suppressed. Furthermore, since the connector 11 includes the shielding terminal 27 for connecting to the shielding elements 14c of the shielded cables 14 and to the grounding terminal 13b of the matching connector 13 by connecting the housing 21 to the matching connector 13, the shielding elements 14c can be easily connected to the grounding terminal 13b to suppress the emission of electromagnetic waves from the shielded cables 14. Thus, due to the fact that the shielding terminal 27 is provided between the majority of shielded cables 14 in the housing 21, a configuration orThe design can be simplified and a reduction in size can be achieved, for example compared to a multi-layered structure in which a shielding shell is arranged outside an inner housing and an outer housing is furthermore arranged outside the shielding shell as before.

[0035] (2) Since the electromagnetic shielding shell 22 is adjusted to electrically contact the sheathing 12, which is a conductive element, at three or more points, the emission of electromagnetic waves can be satisfactorily suppressed.

[0036] (3) Since the electromagnetic shielding shell 22 includes the grounding projections 22b, which project to contact the sheath 12, which is a conductive element, the electromagnetic shielding shell 22 can be brought into contact with the sheath 12 at an effective position while maintaining a simple configuration. That is, the electromagnetic shielding shell 22 can be raised due to component accuracy or the like and need not, and may not, make contact at the effective position, even if an attempt is made to bring the electromagnetic shielding shell 22 into surface contact with the sheath 12 over a wide area. However, by avoiding this, the electromagnetic shielding shell 22 can be brought into contact with the sheath 12 at the effective position.

[0037] (4) The electromagnetic shielding shell 22 is or is configured to electrically contact the casing 12 at least at three points by means of the pair of grounding projections 22b and the screw 30, which is screwed or threaded into the casing 12 by the electromagnetic shielding shell 22. In this way, the electromagnetic shielding shell 22 can be stably fixed to the casing 12 by being electrically connected to the casing 12 at three effective points, while maintaining a simple configuration.

[0038] (5) Since the shielding terminal is made from the bent conductive sheet material, the shielding terminal 27 can be easily manufactured. Furthermore, since the grounding terminal 13b is connected to the parallel sections 27a while inserted between the pair of parallel sections 27a when the housing 21 is connected to the matching connector 13, the shielding terminal 27 and the grounding terminal 13b can be connected with a high degree of reliability, compared, for example, to the case where the shielding terminal 27 and the grounding terminal 13b are connected only by a contact piece configured or constructed to make contact in a single direction.

[0039] This embodiment can be modified and implemented as follows. This embodiment and the following modifications can be combined and implemented without any technical contradiction.

[0040] Although the electromagnetic shielding shell 22 is configured to electrically contact the sheathing 12, which is a conductive element, at three or more points in the above embodiment, there is no limitation thereon and the electromagnetic shielding shell 22 may contact the sheathing 12 at two or fewer points.

[0041] Although the electromagnetic shielding shell 22 includes the grounding projections 22b, which project to contact the sheathing 12, which is a conductive element, in the above embodiment, there is no restriction or limitation on this, and the grounding projections 22b may or may not be provided. Furthermore, the sheathing 12 may be provided with a projection (or projections) that projects towards the electromagnetic shielding shell 22, and the electromagnetic shielding shell 22 and the sheathing 12 may be brought into contact at an effective position.

[0042] Although the electromagnetic shielding shell 22 is configured to electrically contact the casing 12 via the pair of grounding projections 22b and the screw 30, which is threaded or screwed into the casing 12 by the electromagnetic shielding shell 22, in the above embodiment, there is no limitation to this configuration, and the electromagnetic shielding shell 22 can, for example, be fixed by a configuration different from the screw 30. In such a case, the electromagnetic shielding shell 22 and the casing 12 can be brought into contact by a different configuration.

[0043] Although the shield terminal 27 is configured such that the ground terminal 13b is connected to the parallel sections 27a while being inserted between the pair of parallel sections 27a when the housing 21 is connected to the matching connector 13 in the above embodiment, there is no restriction on this and the shield terminal 27 may, for example, be connected to the ground terminal 13b only by a contact piece configured to make contact in a single direction.

[0044] The connector 11 of the embodiment can be called a wiring-side connector. The mating connector 13 of the embodiment can be called a connector receptacle. The mating connector 13, the terminals 13a, and the grounding terminal 13b of the embodiment can be called a connector on the side of an electrical device. A combination of the connector 11 and the mating connector 13 of the embodiment is called a coupling structure. The body section 21a of the housing 21 of the embodiment can be called a terminal receiving chamber. The wire insertion section 21b of the embodiment can be called a wire pull-out port or wire pull-out opening, which is configured to pull out or guide the shielded cables 14 in a wire pull-out direction. As shown in Fig.As shown in Figure 5, the lower housing 26 of the embodiment includes an opening into which the terminals 13a and the grounding terminal 13b of the mating connector 13 are inserted in the mounting direction, and this opening can be called a connection port or a connection opening. The connection port of the lower housing 26 is configured to allow the sliding contact of the terminals 13a and the socket terminals 25 in the mounting direction and the sliding contact of the grounding terminal 13b and the shield terminal 27 in the mounting direction. A combination of the housing 21 and the lower housing 26 can be called a wiring-side connector housing or a wiring-side connector housing.
