Modes for Carrying Out the Invention

[0010] Hereinafter, the connector according to this embodiment will be described in detail with reference to the drawings. Note that the dimensional ratios in the drawings are exaggerated for convenience of explanation and may be different from the actual ratios.

[0011] FIG. 1 is a perspective view of a connector 1 according to this embodiment. FIG. 2 is an exploded perspective view of the connector 1. FIG. 3 is a cross-sectional view of the connector 1 taken along line III-III of FIG. 1. FIG. 4 is a cross-sectional view of the connector 1 taken along line IV-IV of FIG. 3. The connector 1 is, for example, a high-voltage connector that can be adopted in the power supply system of electronic devices such as an inverter or a motor mounted on an electric vehicle or a hybrid vehicle. In this embodiment, the connector 1 is attached to, for example, the power supply system of a two-phase motor (not shown) as a motor.

[0012] As the power supply system of the two-phase motor, there are two electric wires 100, namely, a first electric wire 100a and a second electric wire 100, in advance. Each electric wire 100 has a core wire 101 that is a conductor and a covering portion 102 that is an insulator covering the core wire 101. One terminal of the electric wire 100 is connected to the two-phase motor, and the other terminal of the electric wire 100 is connected to the connector 1. Note that the electric wire 100 may actually have a core wire 101 composed of a plurality of strands and a covering portion 102, but in the following figures, it is simply drawn as one electric wire member.

[0013] The connector 1 first includes, as a group of components related to electrical connection, a plurality of terminals 10, an inner housing 20, an outer housing 30, and a cover housing 40. In this embodiment, a combination of the inner housing 20, the outer housing 30, and the cover housing 40 constitutes a non-metallic member that encloses the terminals 10 and the electric wires 100 when assembled.

[0014] In each electric wire 100, at the terminal on the side connected to the connector 1, the covering portion 102 is removed and the terminal portion 101a of the core wire 101 is exposed.

[0015] As a plurality of terminals 10, in the present embodiment, corresponding to a two-phase motor, there are two terminals 10, a first terminal 10a and a second terminal 10b. The first terminal 10a is attached to the end of the first electric wire 100a. The second terminal 10b is attached to the end of the second electric wire 100b.

[0016] The two terminals 10 are each a female terminal made of metal and have a connection portion 11 and a joining portion 12. These two terminals 10 may have the same shape as each other or may have different shapes from each other.

[0017] The connection portion 11 is a cylindrical portion into which a rod-shaped male terminal as an external terminal of an external connector can be inserted. The connection portion 11 has a leaf spring portion that presses a part of the male terminal against the inner wall portion of the connection portion 11 in order to stably maintain the conduction state with the inserted male terminal. The leaf spring portion may be a portion integrated with the connection portion 11 or may be a separately prepared leaf spring member installed inside the connection portion 11 in advance.

[0018] The joining portion 12 is a flat plate portion for joining the terminal portion 101a of the core wire 101. Assuming that one end in the axial direction of the connection portion 11 is an open end for inserting the male terminal, the joining portion 12 is integrated with the other end in the axial direction of the connection portion 11. In the present embodiment, the joining portion 12 joins the terminal portion 101a of the core wire 101 by ultrasonic joining. Also, in the present embodiment, when the terminal 10 is installed in the connector 1, the axial direction of the connection portion 11 is along the Z direction.

[0019] Also, for each terminal 10, the direction from the joining portion 12 toward the connection portion 11 along the axial direction of the connection portion 11 and the direction from the terminal portion 101a crimped to the joining portion 12 toward the main body of the electric wire 100 are shifted by 90°. That is, when the terminal 10 is installed in the connector 1 and the axial direction of the connection portion 11 is along the Z direction, the terminal portion 101a is crimped in a posture along the Y direction with respect to the joining portion 12. At this time, each electric wire 100 extends from the terminal portion 101a in a direction opposite to the Y direction starting from the terminal portion 101a crimped to the joining portion 12.

[0020] Note that the specific shape of the joint portion 12 may be different for each of the two terminals 10. Further, in this embodiment, the terminal 10 is assumed to have a flat joint portion 12 for joining the terminal portion 101a by ultrasonic bonding. However, instead of the joint portion 12, the terminal 10 may have a crimping portion to which the terminal portion 101a is crimped.

[0021] The inner housing 20 is made of, for example, synthetic resin, and is an insulating member that protects the terminals 10 by holding the two terminals 10 inside. The inner housing 20 has a first terminal accommodating portion 21, a second terminal accommodating portion 22, a base portion 24, and a reinforcing structure portion 25.

[0022] The first terminal accommodating portion 21 is a cylindrical portion that accommodates the connecting portion 11 of the first terminal 10a. The second terminal accommodating portion 22 is a cylindrical portion that accommodates the connecting portion 11 of the second terminal 10b. The first terminal accommodating portion 21 and the second terminal accommodating portion 22 each accommodate the connecting portion 11 such that the opening direction of the connecting portion 11 to be accommodated inside, that is, the direction opposite to the direction in which the male terminal is inserted, is common along the Z direction. The tip portions of the first terminal accommodating portion 21 and the second terminal accommodating portion 22 each open in the Z direction and do not hinder the entry of the male terminal into the connecting portion 11.

[0023] Further, as an example, the first terminal accommodating portion 21 and the second terminal accommodating portion 22 are arranged in parallel along the X direction defined below. Note that the first terminal accommodating portion 21 and the second terminal accommodating portion 22 may be arranged in two stages along the Y direction defined below. In this case, for example, the first terminal accommodating portion 21 may be arranged in the lower stage in the Y direction, and the second terminal accommodating portion 22 may be arranged in the upper stage in the Y direction.

[0024] The base portion 24 is a flat portion that supports the first terminal accommodating portion 21 and the second terminal accommodating portion 22. The base portion 24 has a front portion 24a and a back portion 24b on the opposite side of the front portion 24a. The front portion 24a supports the base ends of the first terminal accommodating portion 21 and the second terminal accommodating portion 22. The internal spaces of the first terminal accommodating portion 21 and the second terminal accommodating portion 22 are open from the back portion 24b in the direction opposite to the Z direction.

[0025] The reinforcing structure 25 is a structure formed of reinforcing ribs to ensure the strength of the inner housing 20. The reinforcing structure 25 is provided on the rear surface 24b side of the base 24 so as not to interfere with the arrangement of the terminals 10 and the electric wires 100.

[0026] Fig. 5 is a perspective view of the outer housing 30 in which the terminals 10 and the electric wires 100 are arranged. Fig. 6 is a perspective view of the outer housing 30 in this embodiment.

[0027] The outer housing 30 is made of, for example, synthetic resin, and is an insulating member that protects the two terminals 10 as a whole by accommodating at least a portion of the inner housing 20 and the joints 12 of each terminal 10. The outer housing 30 has a housing main body 31, a connector opening 32, and a wire pull-out portion 33.

[0028] The housing main body 31 is a box-like portion defined by the Z direction (first direction) as its length, the Y direction (second direction) perpendicular to the Z direction as its height, and the X direction (third direction) perpendicular to both the Z direction and the Y direction as its width. The housing main body 31 has a front wall 34, an annular side wall 35, and a plurality of support pieces 36.

[0029] The front wall 34 is a wall perpendicular to the Z direction and supports the connector opening 32 and the wire pull-out portion 33 so as to be spaced apart from each other in the Y direction. The planar shape of the front wall 34 is a substantially rectangular shape defined by a long side roughly aligned with the Y direction and a short side roughly aligned with the X direction. Furthermore, a first wire contact portion 37 is provided on the wall surface of the front wall 34 facing the inside of the housing main body 31. The first wire contact portion 37 faces the second wire contact portion 45 while being spaced apart from it when a cover housing 40 (described later) is attached to the outer housing 30. The shape of the first wire contact portion 37 is roughly symmetrical to the shape of the second wire contact portion 45 in the Z direction.

[0030] Each of the first wire contact portions 37 has a first contact groove 37a extending in the Y direction and including a curved surface that matches the side shape of each of the electric wires 100 routed inside the housing main body 31. The first contact groove 37a receives and contacts a portion of the side surface of each of the electric wires 100. Each of the first contact grooves 37a of the first wire contact portions 37 is formed with a plurality of first protrusions 38 that protrude from the first contact groove 37a. Each of the first contact grooves 37a further has a pair of side walls 37c, 37d in the X direction. In this embodiment, the height of the side wall 37c on the inner side in the X direction (inner side in the width direction) of the pair of side walls 37c, 37d from the front wall 34 is greater than the height of the side wall 37d on the outer side in the X direction (outer side in the width direction) from the front wall 34 (see FIG. 4).

[0031] The annular side wall 35, together with the front wall 34, forms an internal space that accommodates at least the joint portion 12 of each terminal 10. One annular end of the annular side wall 35 in the Z direction is continuous with the peripheral edge of the front wall 34. The other annular end of the annular side wall 35 in the Z direction is an opening end 35a that forms an opening facing the front wall 34. When the connector 1 is assembled, the two terminals 10, each attached to an end of an electric wire 100, are accommodated inside the housing main body 31 through the openings formed by the opening ends 35a.

[0032] The support piece 36 is provided on the outer wall surface 35b of the annular side wall 35 and has a fitting hole 36a into which an annular collar (not shown) is fitted. The fitting hole 36a penetrates the support piece 36 along the Z direction.

[0033] The connector front end portion 32 has a front end 32a with an oval long hole-shaped cross section that opens in the Z direction, and is a cylindrical portion that fits with a part of an external connector (not shown) having male terminals when the external connector is connected to the connector 1. The connector front end portion 32 is provided so as to protrude in the Z direction from the front wall 34 of the housing main body portion 31. The front end 32a penetrates between the outside of the outer housing 30 and the inside of the housing main body portion 31, and can accommodate the inner housing 20. In the oval long hole-shaped cross section of the front end 32a, the X direction is the longitudinal direction in accordance with the arrangement relationship between the first terminal accommodating portion 21 and the second terminal accommodating portion 22 in the inner housing 20.

[0034] The wire lead-out portion 33 is a cylindrical portion for leading out two wires 100 from the inside of the housing main body portion 31 to the outside of the outer housing 30 through a through space with an oval long hole-shaped cross section that opens in the Z direction. The wire lead-out portion 33 is provided so as to protrude in the Z direction from the front wall 34 of the housing main body portion 31. In the oval long hole-shaped cross section of the through space, the X direction is the longitudinal direction so that the two wires 100 are arranged side by side in the X direction in accordance with the arrangement relationship between the first terminal accommodating portion 21 and the second terminal accommodating portion 22 in the inner housing 20.

[0035] That is, according to the structure of the outer housing 30, in the connector 1, the direction in which the front end 32a of the connector front end portion 32 faces, that is, the direction of connection to the external connector, and the direction in which the two wires 100 are led out from the wire lead-out portion 33 are along the same direction as each other. In the present embodiment, the direction in which the front end 32a of the connector front end portion 32 faces and the direction in which the two wires 100 are led out from the wire lead-out portion 33 are along each other in the Z direction.

[0036] FIG. 7 is a perspective view of the cover housing 40 in the present embodiment as viewed from the side opposite to FIG. 2.

[0037] The cover housing 40 is made of, for example, a synthetic resin. This cover housing 40 is an insulating member that covers an opening formed by an open end 35a in a state where each terminal 10 with a terminal portion 101a joined to a joint portion 12 is housed together with the terminal portion of each electric wire 100 inside the housing main body portion 31 of the outer housing 30. The cover housing 40 has a main body wall 41, a plurality of locking portions 42, a packing mounting portion 43, a cover reinforcing rib 44, a second electric wire contact portion 45, an electric wire regulating portion 46, and a plurality of cylindrical boss portions 47.

[0038] The main body wall 41 is a flat plate portion having an outer peripheral edge 41a along the open end 35a of the housing main body portion 31 when the cover housing 40 is attached to the outer housing 30. The inner wall surface 41b of the main body wall 41 faces the front wall 34 of the housing main body portion 31 when the cover housing 40 is attached to the outer housing 30.

[0039] The plurality of locking portions 42 are respectively provided on the outer peripheral edge 41a of the main body wall 41 at intervals from each other in the circumferential direction along the outer peripheral edge 41a. A plurality of engaging portions 39a are provided on the outer surface portion of the annular side wall 35 of the housing main body portion 31. Each locking portion 42 suppresses the detachment of the cover housing 40 from the outer housing 30 by engaging with the engaging portion 39a on the annular side wall 35 when the cover housing 40 is attached to the outer housing 30.

[0040] The packing mounting portion 43 is a cylindrical portion on which a cover packing 61 described later can be mounted. By mounting the cover packing 61 on the outer peripheral surface of the packing mounting portion 43, the cover packing 61 is held by the cover housing 40.

[0041] The cover reinforcing rib 44 is provided on the inner wall surface 41b so as not to hinder the arrangement of each terminal 10 and each electric wire 100 in order to ensure the strength of the cover housing 40.

[0042] The second wire contact portion 45 is provided on the inner wall surface 41b and contacts each wire 100 when the cover housing 40 is attached to the outer housing 30. The second wire contact portion 45 has a second contact groove 45b that extends in the Y direction and includes a curved surface that conforms to the side surface shape of each wire 100 routed inside the housing main body portion 31. The second contact groove 45b contacts while accommodating a part of the side surface of each wire 100. Further, a plurality of second protrusions 48 are formed so as to protrude from the second contact groove 45b of the second wire contact portion 45, respectively. Furthermore, the second contact groove 45b has a pair of side wall portions 45c and 45d in the X direction, respectively. In the present embodiment, the height of the side wall portion 45d on the outer side in the X direction (outer side in the width direction) of the pair of side wall portions 45c and 45d from the front wall 34 is higher than the height of the side wall portion 45c on the inner side in the X direction (inner side in the width direction) from the front wall 34.

[0043] Here, when the cover housing 40 is attached to the outer housing 30, the second contact groove 45b sandwiches the wire 100 together with the equivalent first contact groove 37a provided in the housing main body portion 31. That is, the second wire contact portion 45, as a combination with the first wire contact portion 37 in the housing main body portion 31, constitutes a wire holding portion that holds each wire 100 and suppresses vibration transmitted from the outside through the wire 100 from reaching the terminal 10.

[0044] The wire regulating portion 46 is provided adjacent to the second wire contact portion 45 on the inner wall surface 41b. The wire regulating portion 46 has two tapered (funnel-shaped) regulating grooves 46a each having an extending direction in the Y direction, and is formed so as to have an increased diameter (or width) as it moves away from the second wire contact portion 45 in the extending direction (Y direction in this embodiment) of the wire 100 from the second wire contact portion 45 side. That is, each of the regulating grooves 46a is formed such that the frontage (or width in the X direction) becomes wider as it moves away from the second wire contact portion 45 in the extending direction (Y direction in this embodiment) of the wire 100 from the second wire contact portion 45 side. The regulating grooves 46a are formed continuously with the second contact groove 45b, and can contact while accommodating a part of the side surface of each wire 100. Further, each of the regulating grooves 46a has a pair of side wall portions 46c, 46d in the X direction. In this embodiment, the height of the side wall portion 46d on the outer side in the X direction (outer side in the width direction) of the pair of side wall portions 46c, 46d from the front wall 34 is higher than the height of the side wall portion 46c on the inner side in the X direction (inner side in the width direction) from the front wall 34 (see FIG. 4).

[0045] Here, when the cover housing 40 is attached to the outer housing 30, the funnel-shaped regulating grooves 46a with a wide frontage regulate each wire 100 to a normal position. That is, even if the wire 100 is slightly displaced outward in the X direction (outer side in the width direction) from the normal position before the attachment of the cover housing 40, the funnel-shaped regulating grooves 46a with a wide frontage pick up each wire 100 and guide it to the normal position (see FIG. 4). For this reason, when the cover housing 40 is attached to the outer housing 30, it is possible to prevent the wire 100 from being caught between the outer housing 30 and the cover housing 40, and the wire 100 can be held in the normal position with respect to the outer housing 30.

[0046] Two boss portions 47 are provided on the inner wall surface 41b and have hole portions 47a extending in the Z direction (see FIG. 2). The two boss portions 47 are arranged in parallel, for example, along the X direction. Each boss portion 47 is individually inserted into a through hole provided in an upper shell of a shield member (not shown) during the assembly of the connector 1.

[0047] In addition, the connector 1 includes a cover packing 61 and a wire packing 62 as waterproof members that prevent moisture from entering the inside of the outer housing 30 from the outside.

[0048] The cover packing 61 is an annular elastic member that is tightly attached in accordance with the opening end 35a of the housing main body portion 31 in the outer housing 30 (see FIG. 3). When the cover housing 40 is attached to the outer housing 30, the cover packing 61 seals the space between the opening end 35a of the housing main body portion 31 and the outer peripheral edge 41a of the cover housing 40.

[0049] The wire packing 62 is an oblong flat plate-shaped elastic member that is tightly attached in accordance with the inner wall surface of the wire lead-out portion 33 in the outer housing 30. Further, the wire packing 62 has two through holes 62a that individually penetrate while being in close contact with each wire 100. The wire packing 62 seals the space between the inner wall surface of the wire lead-out portion 33 and each wire 100 that penetrates the through space of the wire lead-out portion 33.

[0050] In addition, the connector 1 includes a packing holder 75 as a holding member for various packings.

[0051] The packing holder 75 is made of synthetic resin and is attached to the outer housing 30 in order to prevent the wire packing 62 from falling off from the wire lead-out portion 33. The packing holder 75 has two through holes 62a that individually penetrate each wire 100 and is an oblong flat plate-shaped member similar to the shape of the wire packing 62. The packing holder 75 has a plurality of locking portions 76. A plurality of engaging portions 39b are provided on the outer surface portion of the wire lead-out portion 33 of the housing main body portion 31. When the packing holder 75 is attached to the outer housing 30, each locking portion 76 engages with the engaging portion 39b in the wire lead-out portion 33, so that the wire packing 62 is supported by the wire lead-out portion 33. Thereby, the packing holder 75 prevents the wire packing 62 from falling off from the wire lead-out portion 33.

[0052] Also, although not shown, the connector 1 includes an upper shell and a lower shell as shield members for shielding noise. The upper shell is made of metal and can cover the housing main body 31 in a state where the cover housing 40 in the outer housing 30 is attached. The lower shell is made of metal and can cover a part of the front wall 34 of the housing main body 31 and the wire lead-out portion 33 in the outer housing 30.

[0053] Next, the operation and effects of the connector 1 according to the present embodiment will be described.

[0054] The connector 1 is connected to an external connector. The connector 1 includes a plurality of terminals 10, a plurality of wires 100 connected to each terminal 10, and a non-metallic member that, when assembled, encloses the terminals 10 and the wires 100. The non-metallic member has a wire holding portion that sandwiches and holds each wire 100, and a wire regulating portion 46 that is formed adjacent to the wire holding portion and contacts a wire 100 that has deviated from its normal position during the assembly of the housing, and regulates the wire 100 to its normal position.

[0055] Here, the non-metallic member that encloses the terminals 10 and the wires 100 when assembled corresponds to the outer housing 30 and the cover housing 40 in the above example. Also, the wire holding portion corresponds to the combination of the first wire contact portion 37 and the second wire contact portion 45 in the above example.

[0056] According to this connector 1, when the cover housing 40 is attached to the outer housing 30, the wire regulating portion 46 regulates each wire 100 to its normal position. That is, even if the wire 100 has deviated from its normal position before the attachment of the cover housing 40, the wire regulating portion 46 guides each wire 100 to its normal position (see FIG. 4). For this reason, when the cover housing 40 is attached to the outer housing 30, it is possible to prevent the wire 100 from being caught between the outer housing 30 and the cover housing 40, and the wire 100 can be held in its normal position with respect to the outer housing 30.

[0057] As described above, according to the present embodiment, it is possible to provide the connector 1 that can prevent the non-metallic member from biting into the electric wire during the assembly of the non-metallic member that encloses the terminal 10 and the electric wire 100 by being assembled, and can improve the assembly workability.

[0058] In the connector 1, the wire holding portion is a combination of the first wire contact portion 37 and the second wire contact portion 45. The first wire contact portion 37 has a plurality of first contact grooves 37a that come into contact with the electric wire 100 for each electric wire 100. The second wire contact portion 45 faces each first contact groove 37a and has a plurality of second contact grooves 45b that come into contact with the electric wire 100. The wire restricting portion 46 is continuously formed for each second contact groove 45b, and has a restricting groove 46a formed in a tapered shape so as to widen as it moves away from the second contact groove 45b in the extending direction of the electric wire 100 from the second contact groove 45b side.

[0059] Here, the extending direction of the electric wire 100 corresponds to the Y direction in the above example.

[0060] According to this connector 1, when the cover housing 40 is attached to the outer housing 30, the tapered restricting grooves 46a with a wide opening width regulate each electric wire 100 to a normal position. That is, even if the electric wire 100 is displaced from the normal position before the attachment of the cover housing 40, the tapered restricting grooves 46a with a wide opening width pick up each electric wire 100 and guide it to the normal position (see FIG. 4). For this reason, when the cover housing 40 is attached to the outer housing 30, the electric wire 100 is prevented from being bitten between the outer housing 30 and the cover housing 40, and the electric wire 100 can be held in the normal position with respect to the outer housing 30.

[0061] In the connector 1, a plurality of first protrusions 38 protruding from the outer surface of each first contact groove 37a are formed in each first contact groove 37a. A plurality of second protrusions 48 protruding from the outer surface of each second contact groove 45b are formed in each second contact groove 45b.

[0062] According to this connector 1, in the first contact groove 37a, the first protrusions 38 abut or bite into the side surfaces of the respective electric wires 100, and in the second contact groove 45b, the second protrusions 48 abut or bite into the side surfaces of the respective electric wires 100. Therefore, in the wire holding portion formed by the combination of the first wire contact portion 37 and the second wire contact portion 45, each electric wire 100 can be securely held.

[0063] In the connector 1, the non-metallic member includes an outer housing 30 having a housing main body portion 31 and a cover housing 40 that covers an opening formed in the housing main body portion 31. The first contact groove 37a is formed in the housing main body portion 31. The second contact groove 45b and the regulating groove 46a are formed in the cover housing 40.

[0064] Here, the opening formed in the housing main body portion 31 corresponds to the opening end 35a in the above illustration.
