[0018] Hereinafter, the embodiments of the present invention will be described in detail based on the accompanying drawings. In addition, the present invention is not limited to the embodiments described below. In addition, the constituent elements of the embodiments described below include elements that can and are easily replaced by those skilled in the art, or substantially the same elements. In addition, in this specification, ordinal numbers are only used to distinguish between components, parts, parts, positions, directions, etc., and do not indicate order or priority.

[0020] Figure 1 It is a cross-sectional view of a wire harness WH to which the connector 1 according to the embodiment can be applied. Figure 1 The connector 1 of the present embodiment shown is assembled in a wire harness WH arranged in a vehicle such as an automobile. Here, the wire harness WH, for example, bundles a plurality of wires W used for power supply and signal communication as a collection element for connection between various devices mounted on the vehicle, and connects the plurality of wires W to the various devices using a connector 1 or the like. The wire harness WH of the present embodiment, for example, includes a plurality of conductive wires W and a connector 1 provided at the ends of the plurality of wires W. In addition, the wire harness WH may also be configured to include a protector, a fixing, etc. in addition to the above.

[0021] In addition, in the following description, the first direction among the mutually intersecting first direction, second direction and third direction is referred to as the "mating direction X", the second direction is referred to as the "width direction Y", and the third direction is referred to as the "height direction Z". Here, the mating direction X, the width direction Y and the height direction Z are substantially orthogonal to each other. The mating direction X is typically equivalent to the plugging and unplugging direction (mating direction) of the connector 1 and the other-side connector 110, the front-to-back direction (thickness direction) of the connector 1, etc. The height direction Z is typically equivalent to the length direction (up-down direction) of the connector 1, the extension direction of the wire W, the insertion direction of the wire W relative to the connector 1, etc. The width direction Y is typically equivalent to the width direction (left-right direction) of the connector 1, etc. In addition, unless otherwise specified, the directions used in the following description are described as directions in a state where the wire W is assembled in the connector 1.

[0022] The electric wire W is constituted to include, for example, a linear conductor portion W1 having conductivity and an insulating sheath W2 having insulation covering the outside of the conductor portion W1. The electric wire W is an insulated electric wire formed by covering the conductor portion W1 with the insulating sheath W2. The conductor portion W1 of the present embodiment is a core wire formed by bundling a plurality of conductive metal wires, but may also be a twisted core wire formed by twisting the plurality of metal wires. The insulating sheath W2 is a wire sheath covering the outer peripheral side of the conductor portion W1. The insulating sheath W2 is formed by, for example, extruding an insulating resin material (PP, PVC, cross-linked PE, etc., appropriately selected in consideration of wear resistance, chemical resistance, heat resistance, etc.) or the like.

[0023] The electric wires W are formed to extend linearly along the height direction Z, and extend with approximately the same diameter in the height direction Z (extension direction). In addition, the cross-sectional shape of the conductor portion W1 of the electric wire W (the cross-sectional shape intersecting the height direction Z) is formed into a substantially circular shape, and the cross-sectional shape of the insulating sheath W2 is formed into a substantially circular ring shape, and the electric wire W as a whole is formed into a substantially circular cross-sectional shape. The insulating sheath W2 is stripped off at least one end of the electric wire W, and a terminal 3 (see FIG. 3 ) described later is crimped to the conductor portion W1 exposed from the insulating sheath W2. Figure 4 ).

[0024] Here, the connector 1 of the present embodiment and the counterpart device 100 (see Figure 1) are mechanically and electrically connected. The connector 1 is inserted into the connector insertion hole 103 formed in the frame 101 of the counterpart device 100 to engage with the counterpart connector 110, and an electrical connection portion is formed between the counterpart connector 110. The connector 1 is configured to include, for example: a housing 2 having a cylindrical portion 11A that engages with the counterpart connector 110; and a fastening component 40 that is inserted from a through hole 2a formed on one end face of the housing 2 in the engagement direction X, and is fixed to a fixed wall surface 103a of the counterpart device 100 when the cylindrical portion 11A is engaged with the counterpart connector 110. One end face of the housing 2 is an end face on the side opposite to the cylindrical portion 11A in the engagement direction X.

[0025] The connector insertion hole 103 is provided on the wall surface 102 on one side (connector 1 side) of the mating direction X of the frame 101 of the counterpart device 100. The connector insertion hole 103 is, for example, a recessed portion that is recessed from the wall surface 102 toward the other side of the mating direction X and is open toward one side of the mating direction X. The counterpart connector 110 is accommodated inside the connector insertion hole 103. The connector insertion hole 103 is a portion into which the cylindrical portion 11A is inserted and mated when the connector 1 is mated with the counterpart connector 110. The opening shape of the connector insertion hole 103 is formed along the outer diameter shape of the cylindrical portion 11A. The opening shape of the connector insertion hole 103, for example, as viewed from the mating direction X, is formed into a substantially elliptical shape.

[0026] The fixing wall surface 103a is a wall surface at the bottom of the connector insertion hole 103, and is a portion where the connector 1 is fixed by the fastening member 40. The fixing wall surface 103a is formed into a uniform flat surface. In addition, a fastening hole 104 for fastening the fastening member 40 is provided on the fixing wall surface 103a. When the connector 1 is fitted with the counterpart connector 110, the bolt 41 of the fastening member 40 is fastened to the fastening hole 104. The fastening hole 104 is a hole having a threaded engagement groove formed on the inner circumferential surface, and the shaft portion 41b of the bolt 41 is threadedly engaged.

[0027] Figure 2 is a perspective view of the connector 1, Figure 3 is a plan view of connector 1, Figure 4 is an exploded perspective view of the connector 1. Figure 2 to Figure 4 As shown, the connector 1 is configured to include, for example: a housing 2 composed of a combination of a plurality of elements including a housing 10, a shield cover 20, etc.; a plurality of seals 30, 60; a fastening member 40; and a sealing member 50 described later. The connector 1 is used, for example, in a hybrid vehicle, an electric vehicle, etc., in a wiring harness WH having a power supply wire W for supplying power from an inverter to a motor. In addition, in the present embodiment, an example is given in which the connector 1 is configured as a male connector and the counterpart connector 110 is configured as a female connector, but the present invention is not limited to this example.

[0028] The housing 10 is a portion of the outer shell 2 that holds the terminal 3 inside and has a cylindrical portion 11A that fits with the counterpart connector 110. Figure 4 As shown, the housing 10 is composed of a combination of multiple elements. Specifically, the housing 10 is composed of, for example, a housing body 11, a rear cover 12, a front retainer 13, and an inner housing 14. The housing body 11, the rear cover 12, the front retainer 13, and the inner housing 14 are respectively formed of an insulating resin material. In the present embodiment, the cylindrical portion 11A is provided in the housing body 11 in the housing 10, and protrudes in a cylindrical shape from the housing body 11 toward the other side of the mating direction X (the side of the other side connector 110).

[0029] The shell body 11 and the back cover 12 are components that accommodate the terminals 3 inside by being assembled with each other. The terminals 3 are male terminal fittings made of conductive metal material, and are electrically connected to the female terminals of the other-side connector 110. In the present embodiment, four terminals 3 are provided in the shell body 11 at intervals in the width direction Y. The terminals 3 are configured to include, for example, an electrical connection portion electrically connected to the female terminals of the other-side connector 110 and a wire crimping portion electrically connected to the end of the wire W. In addition, an example is given of a case where the shell body 11 and the back cover 12 accommodate four terminals 3 in a state where they are assembled with each other, but the number of the terminals 3 is not limited to this.

[0030] In addition, the housing body 11 is formed to have openings on both sides of the mating direction X, for example. When the terminal 3 is accommodated in the cylindrical portion 11A, the terminal 3 is exposed to the outside from the opening on the other side of the mating direction X of the housing body 11, and on the other hand, the opening on one side of the mating direction X of the housing body 11 is closed by the back cover 12. The housing body 11 is formed to have a substantially rectangular shape when viewed from the mating direction X, for example. In the mating state in which the cylindrical portion 11A is mated with the mating connector 110, the housing body 11 is opposed to the wall surface 102 of the mating device 100. In addition, a plurality of wire insertion portions 15 are provided at the lower end of the housing body 11.

[0031] The wire insertion portion 15 is a portion through which the power supply wire W is inserted. The wire insertion portion 15 is formed so as to protrude downward from the lower end portion of the housing body 11 along the height direction Z. The wire insertion portion 15 is formed in a cylindrical shape, and the wire W is wired inside the wire insertion portion 15 along the height direction Z. That is, the housing body 11 holds the terminal 3 along the mating direction X, and leads the wire W along the height direction Z orthogonal to the mating direction X. Here, four wire insertion portions 15 are arranged in the housing body 11 along the width direction Y, and the wires W are inserted into each of the four wire insertion portions 15.

[0032] The rear cover 12 is a member for closing the opening of the housing body 11 from one side in the fitting direction X. The rear cover 12 includes, for example, a cover portion 12b that covers the opening of the housing body 11 and a plurality of stopper portions 12a that are stoppered to the outer peripheral surface of the housing body 11. The rear cover 12 is integrated with the housing body 11 by snapping with the stopper portions 12a in a state where the cover portion 12b covers the opening of the housing body 11.

[0033] The front holder 13 is, for example, a member for holding the seal 30 between the front holder 13 and the housing body 11. The front holder 13 is formed in a cylindrical shape along the outer peripheral surface of the cylindrical portion 11A, and is fitted with the outer peripheral surface of the cylindrical portion 11A. The front holder 13 is formed in a substantially elliptical cylindrical shape when viewed from the fitting direction X. In a state where the seal 30 is sandwiched between the front holder 13 and the housing body 11, the front holder 13 is integrated with the cylindrical portion 11A by claw fitting or the like.

[0034] The seal 30 prevents foreign matter such as moisture and dust from entering the interior of the connector 1 from the annular gap between the mating connector 110 and the outer peripheral surface of the cylindrical portion 11A. The seal 30 is formed of a member that can be elastically deformed, such as rubber or resin. The seal 30 is formed, for example, in a substantially elliptical cylindrical shape along the outer peripheral surface of the cylindrical portion 11A, and is fitted with the outer peripheral surface of the cylindrical portion 11A. In the mating state where the cylindrical portion 11A is fitted with the mating connector 110, the seal 30 is interposed between the mating connector 110 and the cylindrical portion 11A on one side of the front retainer 13 in the mating direction X.

[0035] The inner housing 14 is a component formed separately from the housing body 11, and is a component that accommodates and holds the terminal 3 along the fitting direction X in a state of being mounted on the inner side of the cylindrical portion 11A. The inner housing 14 is provided with a plurality of insertion holes 14a through which the terminal 3 is inserted along the fitting direction X. The plurality of insertion holes 14a are arranged side by side in the width direction Y. In other words, the plurality of terminals 3 are held in a state of being separated from each other in the width direction Y by the inner housing 14.

[0036] The shield cover 20 is a portion of the housing 2 that covers the terminals 3 and the periphery of the wires W to suppress the noise generated by the wires W from leaking to the outside of the connector 1. Figure 4 As shown, the shield case 20 is composed of a combination of a plurality of components. Specifically, the shield case 20 is composed of, for example, a case body 21 and a lower case 25. The case body 21 and the lower case 25 are each formed of, for example, a conductive metal material.

[0037] The cover body 21 is formed in a barrel shape, for example, so as to cover one side of the housing 10 in the fitting direction X. That is, the cover body 21 is provided with a storage space portion, which is open toward the other side of the fitting direction X and stores the rear cover 12 of the housing 10 and a part of the housing body 11. In addition, the cover body 21 is provided with a through hole 2a through which the bolt 41 of the fastening member 40 is inserted along the fitting direction X. The through hole 2a is connected to the through hole provided in the rear cover 12 and the center hole provided in the housing body 11 (see Figure 5 ) are connected in parallel in the mating direction X.

[0038] In addition, a wire holding portion 22 for holding the wire W is provided at the lower end portion of the cover body 21 (see Figure 4 The wire holding portion 22 has a substantially U-shaped cross section that is open toward the other side of the mating direction X, and the wires W are routed inside the U-shaped cross section along the height direction Z. Here, four wire holding portions 22 are arranged side by side along the width direction Y on the cover body 21, and the wires W are respectively inserted into the four wire holding portions 22.

[0039] The lower cover 25 is a portion that fixes the housing body 11 to the shield cover 20 by being fastened to the housing body 21 by means of fasteners 70 or the like. The lower cover 25 is located on the other side (the side opposite to the housing body 21) of the fitting direction X relative to the housing body 11. The lower cover 25 is fixed to the housing body 21 by fastening with two fasteners 70 in a state where the wire insertion portion 15 of the housing body 11 is sandwiched between the housing body 11 along the fitting direction X.

[0040] Figure 5 is a cross-sectional view of the connector 1. Figure 5 As shown, the fastening component 40 is a component for fixing the connector 1 to the fixed wall surface 103a of the above-mentioned counterpart device 100. The fastening component 40 is configured to include, for example, a bolt 41 and a waterproof gasket 42. The bolt 41 includes: a shaft portion 41b extending along the mating direction X and a head portion 41a provided at one end portion of the shaft portion 41b in the mating direction X and having a larger diameter than the shaft portion 41b. The shape of the head portion 41a as viewed from the mating direction X is configured to be, for example, a hexagon. The head portion 41a is locked to the peripheral portion of the through hole 2a in one end surface of the shield cover 20 in the mating direction X.

[0041] The shaft portion 41b is a portion that is inserted through the through hole 2a of the shield cover 20, the through hole of the back cover 12, and the center hole of the housing body 11 along the mating direction X. The shaft portion 41b is formed in a cylindrical shape. A spiral screw groove is formed on the surface of the shaft portion 41b along the mating direction X. The bolt 41 is fastened to the fastening hole 104 of the above-mentioned fixed wall surface 103a by screwing with the fastening hole 104 in the state where the shaft portion 41b is inserted through the through hole 2a, etc. That is, the connector 1 is fixed to the fixed wall surface 103a of the other device 100 in a state where the bolt 41 passes through the inside of the cylindrical portion 11A along the mating direction X. The bolt 41 is inserted into the center hole of the cylindrical portion 11A and is located in the center portion between the inner two terminals 3 of the above-mentioned four terminals 3.

[0042] The waterproof gasket 42 includes, for example, a gasket body 42a and a waterproof rubber 42b. The gasket body 42a is a component interposed between the head 41a of the bolt 41 and the peripheral edge of the through hole 2a in one end face of the mating direction X of the shield cover 20. The gasket body 42a is formed in an annular shape (ring shape). The gasket body 42a has a function of suppressing interference between the head 41a of the bolt 41 and the shield cover 20.

[0043] The water-stop rubber 42b suppresses moisture and the like from entering the through hole 2a side from the annular gap between the gasket body 42a and the head 41a of the bolt 41. The water-stop rubber 42b is formed by a component that can be elastically deformed, such as rubber. The water-stop rubber 42b is between the inner surface of the gasket body 42a and the shaft 41b of the bolt 41. The water-stop rubber 42b is formed into a circular ring (ring shape) along the inner surface of the gasket body 42a. In addition, in the present embodiment, a waterproof gasket 42 is also provided on the other end face side of the mating direction X of the rear cover 12. That is, on the fastening component 40, a pair of waterproof gaskets 42 are provided at intervals from each other in the mating direction X.

[0044] In addition, in the present embodiment, a sealing component 50 is provided on the shaft portion 41b of the bolt 41 adjacent to the waterproof rubber 42b in the mating direction X. The sealing component 50 prevents moisture and the like from entering the interior of the connector 1 from the annular gap between the outer peripheral surface of the shaft portion 41b and the inner surface of the through hole 2a. The sealing component 50 is formed of a component that can be elastically deformed, such as rubber and resin. The sealing component 50 is, for example, between the outer peripheral surface of the shaft portion 41b and the inner surface of the through hole 2a, and between the outer peripheral surface of the shaft portion 41b and the inner surface of the through hole of the rear cover 12. The sealing component 50 is, for example, formed in a cylindrical shape along the outer peripheral surface of the shaft portion 41b, and is mated with the outer peripheral surface of the shaft portion 41b. The sealing component 50 is also called a bushing or the like.

[0045] In addition, in the present embodiment, a seal 60 is provided between the shell body 11 and the rear cover 12. The seal 60 prevents foreign matter such as moisture and dust from entering the interior of the connector 1 from the annular gap between the shell body 11 and the rear cover 12 (shielding cover 20). The seal 60 is formed of a component that can be elastically deformed, such as rubber or resin. The seal 60 is, for example, formed in an annular shape along the outer peripheral surface of the rear cover 12 and is fitted with the outer peripheral surface of the rear cover 12. When the rear cover 12 is integrated with the shell body 11, the seal 60 is located between the end of one side of the fitting direction X of the shell body 11 and the outer peripheral surface of the rear cover 12. Furthermore, in the present embodiment, the fastening component 40 is provided on the inner side of the waterproof area based on the above-mentioned two seals 30 and 60.

[0046] Next, the connector 1 having the above structure is connected to the counterpart connector 110 (see Figure 1 ) is fitted and fixed to the fixed wall surface 103a of the other device 100. First, the operator inserts the bolt 41 of the fastening member 40 into the fastening hole 104 of the fixed wall surface 103a and screws it in, while inserting the bolt 41 into the through hole 2a of the shield cover 20, the through hole of the rear cover 12, and the center hole of the housing body 11 in the connector 1.

[0047] At this time, the bolt 41 of the connector 1 penetrates the center of the cylindrical portion 11A along the mating direction X, thereby preventing the connector 1 from tilting relative to the fixed wall surface 103a. Then, the operator further tightens the bolt 41, so that the cylindrical portion 11A is mated with the counterpart connector 110, and the terminal 3 is connected to the terminal of the counterpart connector 110. In this way, the bolt 41 of the fastening member 40 functions as an auxiliary bolt when the cylindrical portion 11A is mated with the counterpart connector 110.

[0048] In the conventional connector, the bolt 41 is disposed outside the cylindrical portion 11A, that is, at a position away from the center of the cylindrical portion 11A, so that the connector 1 may be tilted relative to the fixed wall surface 103a when the bolt 41 is tightened. In this regard, according to the present embodiment, since the bolt 41 penetrates the center of the cylindrical portion 11A along the fitting direction X, it is possible to suppress the connector 1 from tilting relative to the fixed wall surface 103a when the bolt 41 is tightened. Therefore, it is possible to suppress the terminal 3 from contacting the terminal of the other side connector 110 in an inclined state and causing distortion between the two terminals 3.

[0049] As described above, the connector 1 and the wiring harness WH of the present embodiment include: a housing 2, which holds the terminal 3 provided at the end of the electric wire W inside, and has a cylindrical portion 11A that is engaged with the other-side connector 110 of the other device 100 (connection object) along the engagement direction X; a seal 30, which seals the annular space between the outer peripheral surface of the cylindrical portion 11A and the other-side connector 110; a fastening component 40, which is installed in a manner that passes through the inside of the cylindrical portion 11A along the engagement direction X from a through hole 2a formed on one end surface of the housing 2 in the engagement direction X, and is fixed to the fixed wall 103a of the other device 100 when the cylindrical portion 11A is engaged with the other-side connector 110; and a sealing component 50, which seals the annular gap between the outer peripheral surface of the fastening component 40 and the inner surface of the through hole 2a. According to this structure, the connector 1 and the wire harness WH can be provided with the fastening member 40 inside the cylindrical portion 11A, i.e., inside the waterproof area of ​​the seal 30, through the sealing member 50. As a result, the connector 1 and the wire harness WH can suppress the enlargement of the housing 2, and can further reduce the size of the housing 2.

[0050] In the connector 1 and the wire harness WH of the present embodiment, the fastening member 40 is configured to include: a bolt 41 inserted into the through hole 2a; and a waterproof gasket 42 having an annular gasket body 42a sandwiched between the head 41a of the bolt 41 and the peripheral edge of the through hole 2a, and an annular waterproof rubber 42b sandwiched between the inner surface of the gasket body 42a and the shaft 41b of the bolt 41 and adjacent to the sealing member 50 in the fitting direction X. According to this structure, the connector 1 and the wire harness WH can further suppress water from penetrating from the through hole 2a to the inside of the housing 2, that is, the inside of the waterproof area based on the seal 30, by the waterproof gasket 42 of the fastening member 40.

[0051] In addition, in the connector 1 and the wiring harness WH of the present embodiment, the electric wires W are led out relative to the housing 2 along the height direction Z intersecting the mating direction X. According to this structure, the connector 1 and the wiring harness WH can be configured more simply, for example, and the fastening member 40 inserted into the through hole 2a, the sealing member 50 for sealing the gap between the outer peripheral surface of the fastening member 40 and the inner surface of the through hole 2a, etc. can be easily provided on one end surface of the housing 2 in the mating direction X.

[0052] It should be noted that, in the present embodiment, the case where the electric wire W is led out along the height direction Z intersecting the fitting direction X relative to the housing 2 is exemplified, but the present invention is not limited to this example. For example, the electric wire W may be led out along the fitting direction X relative to the housing 2, or may be led out along the width direction Y. In addition, in the present embodiment, the case where the housing 2 is composed of a combination of a plurality of components including the housing 10 and the shield cover 20 is exemplified, but the present invention is not limited to this example. For example, the housing 2 may be composed of a single component. In addition, the seal 60 may be provided between the housing 10 and the shield cover 20, for example.

[0053] The above examples illustrate the embodiments of the present invention, but the above embodiments are only examples and are not intended to limit the scope of the invention. The above embodiments can be implemented in various other ways, and various omissions, substitutions, combinations, and changes can be made without departing from the scope of the main purpose of the invention. In addition, the specifications of various structures, shapes, etc. (structure, type, direction, form, size, length, width, thickness, height, quantity, configuration, position, material, etc.) can be appropriately changed and implemented.
