Detailed Description
Hereinafter, embodiments of the connector according to the present invention will be described in detail with reference to the drawings. The present invention is not limited to this embodiment.
Embodiment(s)
One embodiment of the connector according to the present invention will be described with reference to fig. 1 to 9.
Symbol 1 in fig. 1 to 8 denotes a connector according to the present embodiment. The connector 1 includes a terminal fitting 10, a housing 20, and a shield 30 (fig. 4 and 8). In the connector 1, the terminal fitting 10 and the housing 20 are inserted and fitted into a cylindrical mating fitting portion (not shown), whereby the terminal fitting 10 and a mating terminal fitting (not shown) in the mating fitting portion are electrically connected. The connector 1 is inserted into and removed from the mating fitting portion along the axial direction of the mating fitting portion.
For example, the connector 1 is electrically connected to a mating terminal fitting of a mating device (not shown), and the mating device is electrically connected to a device (not shown) at an end of the electric wire We. The partner device is provided with: a metal housing, and a terminal block or mating connector (not shown) having mating engagement portions protruding from opposite walls of the housing. The mating fitting portion is formed in a circular or oblong ring shape in cross section orthogonal to the cylinder axis direction, with the direction orthogonal to the plane-like wall surface of the mating wall body being the cylinder axis direction. The connector 1 is fitted to the mating fitting portion, so that, for example, an inverter as a mating device mounted on a vehicle is electrically connected to a rotating machine as a device at an end of an electric wire We mounted on the vehicle. The connector 1 shown here is fixed to the wall surface of the mating wall body in a state of being fitted and connected to the mating fitting portion.
The terminal fitting 10 is molded from a conductive material such as metal. The terminal fitting 10 has: a terminal connection part 11 which is physically and electrically connected to the counterpart terminal fitting; and an electric wire connection portion 12 that is physically and electrically connected to the end of the electric wire We (fig. 4 and 8). The terminal fitting 10 is mounted to the end of the electric wire We.
For example, with respect to the counterpart terminal connecting portion of the counterpart terminal fitting and the terminal connecting portion 11, one of them is formed in a female terminal shape, and the other is formed in a male terminal shape. Here, the terminal connection portion 11 is formed in a cylindrical female terminal shape, and the counterpart terminal connection portion is formed in a cylindrical male terminal shape fitted into the terminal connection portion 11. The wire connecting portion 12 is physically and electrically connected to the wire We by, for example, crimping or welding the core wire We1 at the end of the wire We.
The electric wire We shown here is a so-called shielded electric wire, and includes: a columnar conductive core wire We1; a cylindrical insulating inner sheath (inner sheath) We2 covering the core wire We1 concentrically; a cylindrical conductive braid We3 in which the inner sheath We2 is concentrically covered; and a cylindrical insulating outer sheath (outer sheath) We4 (fig. 1 and 4) concentrically covering the braid We 3.
The terminal fitting 10 of this example is molded into a linear-shaped terminal fitting in which the terminal connection portion 11 and the wire connection portion 12 are arranged in a straight line. Accordingly, the electric wire We is led out from the electric wire connection portion 12 in the extending direction of the terminal fitting 10 along the straight line. However, the terminal fitting 10 may be configured such that the terminal connection portion 11 and the wire connection portion 12 are disposed in an orthogonal manner, or the like, so as to intersect with each other.
The connector 1 shown here includes a combination of 2 pairs of terminal fittings 10 and electric wires We.
The case 20 is molded from an insulating material such as a synthetic resin. The housing 20 accommodates the terminal fitting 10 and the electric wire We inside. In the case 20, the terminal fitting 10 is held in a housed state, and the electric wire We is led out from the inside to the outside.
The housing 20 has a terminal accommodating portion 21 (fig. 1 to 8) which accommodates the terminal fitting 10 therein and is inserted into the mating portion. The terminal housing 21 shown here is formed in a cylindrical shape and is inserted into and removed from the mating fitting portion along the axial direction of the cylindrical shape. In the case 20 shown here, the terminal accommodating portions 21 are provided for each terminal fitting 10, and the respective terminal accommodating portions 21 are arranged in a direction orthogonal to the cylinder axis direction.
The case 20 includes a wire housing 22 (fig. 4 and 6 to 8) for housing the wire We led out from the wire connection portion 12 and for guiding the wire We from the inside to the outside. The wire housing 22 shown here is formed in a cylindrical shape and is arranged coaxially with the terminal housing 21. Accordingly, the wire housing portion 22 causes the wire We led out from the wire connecting portion 12 to be led out from the inside to the outside in the same direction as the direction in which it is led out. In the case 20 shown here, the wire housing portions 22 are provided for each terminal fitting 10, and the respective wire housing portions 22 are arranged in a direction orthogonal to the cylinder axis direction.
The housing 20 has an annular flange portion 23 between each terminal accommodating portion 21 and each wire accommodating portion 22, and the flange portion 23 protrudes radially outward from each terminal accommodating portion 21 and radially outward from each wire accommodating portion 22 (fig. 8).
The shield 30 is formed of a metallic material such as aluminum or an aluminum alloy. The shield case 30 accommodates the housing 20 and the electric wire We led out from the housing 20 inside. In the shield case 30, the electric wire We led out from the electric wire accommodating portion 22 of the housing 20 is led out from the inside to the outside in a state where the housing 20 is held at the accommodated position. In the shield case 30, the electric wire We led out from the electric wire housing portion 22 is led out from the inside to the outside in the same direction as the leading direction.
The shield case 30 includes a first case member 40 and a second case member 50 (fig. 1 to 8) assembled to each other.
The first cover member 40 shown here has: a cylindrical portion 41 formed in a cylindrical shape with a wire We extraction direction (hereinafter referred to as "wire extraction direction") as a cylindrical axis direction; and a dividing tube 42 that divides the annular end face 41a in the wire-drawing direction of the tube 41 so as to leave a part 41a of the annular end face 41a 1 Is partially protruded in the wire drawing direction (fig. 1, 2, and 4 to 8). On the other hand, the second cover member 50 shown here is formed in a divided cylindrical shape, which is formed in a cylindrical shape by being assembled to the divided cylindrical portion 42 so as to be fitted with the divided cylindrical portion 42. That is, in the shield case 30, one of the structures in which the cylindrical shape is divided into two is the divided cylindrical portion 42, and the other is the second cover member 50.
The tubular portion 41 shown here is formed in an annular tubular shape having an oblong cross section perpendicular to the tubular axis direction. The cylindrical portion 41 shown here accommodates the flange portion 23 side portion of each terminal accommodating portion 21, the flange portion 23, and the flange portion 23 side portion of each wire accommodating portion 22. Accordingly, the cylindrical portion 41 projects each of the wire housing portions 22 from the inside to the outside on the wire drawing direction side, and projects each of the terminal housing portions 21 from the inside to the outside on the opposite side to the wire drawing direction side.
The split cylinder 42 and the second cover member 50 may be formed in any shape as long as they are formed by splitting a cylindrical shape into two parts. For example, the divided cylinder 42 and the second cover member 50 may be members that divide the cylindrical shape equally into two parts, or may be formed into a divided cylinder shape having an opening, and the other may be formed into a divided cylinder shape such as a cover portion that closes the opening.
The split cylinder 42 and the second cover member 50 shown here are formed in a ring shape having an oblong cross section orthogonal to the cylinder axis direction in a state of a mutually assembled cylinder shape. Here, the split cylinder 42 and the second cover member 50 are formed in a split cylinder shape in which the cylindrical shape is equally split into two parts in one and the other in the short side direction of the oblong ring shape. The split cylindrical portion 42 and the second cover member 50 shown here house, inside the cylindrical shape assembled with each other, a protruding portion protruding from the cylindrical portion 41 in each wire housing portion 22 and a portion (hereinafter referred to as "wire drawing portion") Wea (fig. 6 and 7) of each wire We drawn out from the wire housing portion 22. In a state of a tubular shape in which the divided tubular portion 42 and the second cover member 50 are assembled with each other, the electric wire We is led out from the opening of the one end 40a, 50a on the electric wire leading-out direction side (fig. 1).
In addition, in the state where the second cover member 50 is assembled to the divided tubular portion 42, the second cover member 50 has a portion 41a opposite to the annular end surface 41a of the tubular portion 41 in order to suppress penetration of liquid such as water or brine from the gap between the second cover member 50 and the tubular portion 41 1 An opposing end surface 51 of the other end 50b (fig. 4, 5, and 7) disposed opposite to the wire-drawing direction side. Therefore, in the connector 1, the annular end surface 41a of the tubular portion 41 is partially formed with a portion 41a within a range where the first cover member 40 and the second cover member 50 can be assembled 1 The gap between the second cover member 50 and the opposite end surface 51 of the other end 50b is as narrow as possible.
In order to prevent the wire lead-out portions Wea from contacting each other in the cylindrical shape, the split cylindrical portion 42 and the second cover member 50 shown here have partition walls 42a, 52 interposed between the wire lead-out portions Wea, respectively, protruding from the inner peripheral surface (fig. 5, 6, and 8). In the dividing tube 42 and the second cover member 50, 2 semicircular arc-shaped inner peripheral surfaces 40c, 50c (fig. 4, 6 and 8) having the same diameter are formed by the partition walls 42a, 52, respectively. In the divided cylindrical portion 42 and the second cover member 50, 2 columnar space portions are formed in a cylindrical shape in which they are assembled with each other, and 1 wire lead-out portion Wea is disposed in each of the space portions. In the respective partition walls 42a and 52 shown here, at least the front ends of the wire extraction direction side ends 40a and 50a on the projecting direction side are formed as planar top surfaces, and the top surfaces are disposed so as to face each other in a state of a cylindrical shape in which the divided cylindrical portion 42 and the second cover member 50 are assembled.
The assembled first and second cover members 40, 50 screw-fasten the fixing portions 43, 53 provided at the one ends 40a, 50a on the wire drawing direction side to each other by axial force in a direction orthogonal to the wire drawing direction (fig. 4 and 8). Therefore, the first cover member 40 is provided with the fixing portion 43 at one end 40a of the split tube portion 42 on the wire drawing direction side. Further, the second cover member 50 is provided with a fixing portion 53 at one end 50a on the wire drawing direction side.
In the shield case 30 shown here, the fixing portion 43 of the first cover member 40 is provided at one end 40a on the wire drawing direction side of the partition wall 42a, and the fixing portion 53 of the second cover member 50 is provided at one end 50a on the wire drawing direction side of the partition wall 52. Specifically, the fixing portion 43 of the first cover member 40 has a female screw portion 43a (fig. 5 and 8) that is screwed into the male screw portion B1 of the male screw member B. The female screw portion 43a has a direction orthogonal to the top surface of the one end 40a of the partition wall 42a on the wire drawing direction side as the hole axis direction. The fixing portion 53 of the second cover member 50 has a through hole 53a through which the male screw portion B1 is inserted (fig. 5 and 8). The through hole 53a has a direction orthogonal to the top surface of the one end 50a of the partition wall 52 on the wire drawing direction side as a hole axis direction. The fixing portions 43 and 53 are fixed by an axial force generated by screwing the male screw portion B1 and the female screw portion 43a of the male screw member B. In the fixing portion 53 of the second cover member 50, an axial force is received from the seat surface B2 of the male screw member B, and a portion to which the axial force acts becomes an application point of the axial force.
The shield case 30 is provided with: a first direction locking wall 31 for locking the relative movement of the housing 20 in the wire drawing direction at the accommodated position; and a second direction locking wall 32 for locking the relative movement of the housing 20 in the direction opposite to the wire drawing direction (fig. 5) at the accommodated position.
The first direction locking wall 31 is provided at least in the first cover member 40. The first direction locking wall 31 shown here is provided on the inner peripheral surface side of the cylindrical portion 41 of the first cover member 40. Here, a wall surface protruding inward from the inner peripheral surface of the cylindrical portion 41 and facing in the direction opposite to the wire drawing direction is used as the first direction locking wall 31. The tube 41 shown here has an annular wall surface 41b, and the annular wall surface 41b is a wall surface facing in the direction opposite to the wire drawing direction, and is formed in an annular shape along the circumferential direction of the inner peripheral surface (fig. 5). In the cylindrical portion 41, the annular wall surface 41b is used as the first direction locking wall 31. When the housing 20 is positioned at the accommodating completion position in the shield case 30, the first direction locking wall 31 is disposed so as to face the flange 23 of the housing 20 in the wire drawing direction. When the housing 20 is to be moved relatively to the wire-drawing direction side with respect to the shield case 30, the first-direction locking wall 31 locks the flange 23 so as to allow a relative movement amount of the play amount and hold the housing 20 at the housed position. Therefore, in order to suppress the relative movement of the housing 20 in the wire drawing direction at the accommodated position, the flange portion 23 is used as a first-direction engaged wall that engages with the first-direction engaging wall 31.
The second direction locking walls 32 are provided 1 in each of the first cover member 40 and the second cover member 50. The second direction locking wall 32 shown here is provided between one end 50a and the other end 50b of the inner peripheral surface side of the divided cylindrical portion 42 of the first cover member 40 and the inner peripheral surface side of the second cover member 50.
In the dividing tube portion 42, a recess 42b is formed on the opposite side of the dividing wall 42a to the wire drawing direction side so as to recess the inner peripheral surface, and a wall surface 42c of the recess 42b on the opposite side to the wire drawing direction side is projected from the inner peripheral surface (fig. 5). In the divided cylinder 42, the wall surface 42c is used as the second direction locking wall 32. On the other hand, the housing 20 has: an elastically deformable sheet 24A having a wire-drawing direction side as a free end and a side opposite to the wire-drawing direction side as a fixed end; and a claw 24B provided at a free end of the sheet 24A (fig. 5). The sheet body 24A protrudes from between the respective wire accommodating portions 22 of the flange portion 23 and is elastically deformed in a direction orthogonal to the wire drawing direction and the arrangement direction of the respective wire accommodating portions 22. The claws 24B protrude from the free ends of the sheet 24A so as to face the inner peripheral surface side of the divided cylinder 42 when the housing 20 is in the housing completion position.
Inside the shield case 30, the claw 24B is accommodated in the recess 42B when the housing 20 is in the accommodated position. When the housing 20 is to be moved relatively to the opposite side of the shield case 30 from the wire drawing direction side, the second direction locking wall 32 of the first cover member 40 locks the claw 24B so as to allow the relative movement amount of the play amount and hold the housing 20 at the housed position. Therefore, the claw 24B is used as a second direction engaged wall engaged with the second direction engaging wall 32 of the first cover member 40 to suppress relative movement of the housing 20 in the housing-completed position in the direction opposite to the wire drawing direction.
On the other hand, in the second cover member 50, a protrusion 54 protruding from the inner peripheral surface is formed on the opposite side of the partition wall 52 to the wire drawing direction side, and the wall surface of the protrusion 54 on the wire drawing direction side is used as the second direction locking wall 32 (fig. 5). On the other hand, the housing 20 is formed with a connecting wall 25, and the connecting wall 25 connects the outer peripheral surfaces of the respective wire accommodating portions 22 to each other at one end on the wire-drawing direction side, and fills one end on the wire-drawing direction side of the recess 20a between the respective wire accommodating portions 22 (fig. 5 and 8). Inside the shield case 30, when the housing 20 is in the housing-completed position, the protrusion 54 is housed in the recess 20a. When the housing 20 is to be moved relative to the shield case 30 to the opposite side to the wire drawing direction side, the second direction locking wall 32 of the second cover member 50 locks the connection wall 25 so as to allow the relative movement amount of the play amount and hold the housing 20 at the housing completion position. Therefore, the connecting wall 25 serves as a second direction engaged wall engaged with the second direction engaging wall 32 of the second cover member 50 to suppress relative movement of the housing 20 in the direction opposite to the wire drawing direction at the accommodated position.
In the connector 1, the shield case 30 is fixed to the wall surface of the mating wall body in a state of being fitted and connected to the mating fitting portion. The shield case 30 has the other end 40b of the first case member 40 opposite to the wire drawing direction side fixed to the wall surface of the opposite wall body (fig. 1 and 2). Therefore, the first cover member 40 has an annular flange portion 44 (fig. 1 and 2) protruding outward from the outer peripheral surface of the tube portion 41 at the other end 40b of the tube portion 41. The flange 44 is fixed to the wall surface of the opposite wall body by a screw member.
The connector 1 further includes an electrical connection member 61 (fig. 4 and 6 to 9) for electrically connecting the shield 30 to the braid We3 of the electric wire We. The electric connection member 61 is formed of a conductive material such as metal. The electric connection member 61 shown here is provided for each electric wire We. The electric connection member 61 shown here is formed in a cylindrical shape and concentrically covers the wire lead-out portion Wea on the inner side thereof.
Here, at the end of the electric wire We, the outer cover We4 is peeled from the front end to the front of the electric wire lead-out portion Wea, and the braid We3 on the front end side of the electric wire lead-out portion Wea is folded back in a tubular shape to cover the outer peripheral surface of the outer cover We 4. The electric connection member 61 has a first cylindrical portion 61a, and the first cylindrical portion 61a concentrically covers the folded-back portion of the braid We3 from the outside (fig. 4 and 9). The first cylindrical portion 61a is concentrically covered from the outside by a cylindrical fixing member 62. The fixing member 62 is, for example, a so-called fastening ring formed of a conductive material such as metal, and is fastened and pressed to the first cylindrical portion 61a, so that the first cylindrical portion 61a is physically and electrically connected to the folded-back portion of the braid We 3.
The electric connection member 61 has a second cylindrical portion 61b (fig. 4 and 9) that makes contact with the outer peripheral surface and the inner peripheral surface side of the shield case 30 on the same axis as the first cylindrical portion 61 a. The outer peripheral surface of the second cylindrical portion 61b is physically and electrically connected to the semicircular inner peripheral surfaces 40c and 50c of the split cylindrical portion 42 and the second cover member 50, respectively. Therefore, the second cylindrical portion 61b is formed to have an outer peripheral surface having the same radius as the inner peripheral surfaces 40c, 50c of the split cylindrical portion 42 and the second cover member 50, respectively. That is, the second cylindrical portion 61b is formed as a cylindrical portion having a larger diameter than the first cylindrical portion 61 a.
The electric connection member 61 includes a third cylindrical portion 61c (fig. 4) having a larger diameter than the first cylindrical portion 61a and a smaller diameter than the second cylindrical portion 61b, between the first cylindrical portion 61a and the second cylindrical portion 61b and coaxially with the first cylindrical portion 61a and the second cylindrical portion 61 b.
The connector 1 further includes a first seal member 71 that fills a gap between the electric wire We and the shield case 30 so that the liquid that has entered from the outside does not reach the terminal fitting 10 (fig. 4 and 6 to 9). In order to improve the liquid tightness, the connector 1 includes a second seal member 72 (fig. 4 and 6 to 9) that fills a gap between the electric wire We and the housing 20, on the inner side of the first seal member 71.
The first seal member 71 is, for example, a rubber seal member that is elastically deformable, and is disposed between the outer peripheral surface of the electric wire We and the inner peripheral surface of the shield case 30 so as to prevent liquid from entering between the outer peripheral surface of the electric wire We and the inner peripheral surface of the shield case 30 from the outside. The first seal member 71 is formed in an annular shape so as to close an annular gap between the outer peripheral surface of the electric wire We and the inner peripheral surface of the shield case 30. The first seal member 71 is disposed at one end 40a, 50a of each of the first cover member 40 and the second cover member 50, and is disposed closer to the other end 40b, 50b side of each of the first cover member 40 and the second cover member 50 than the point at which the axial force is applied to each of the fixing portions 43, 53 (fig. 4).
The first seal member 71 shown here is provided for each electric wire We. Accordingly, the first seal member 71 is formed in an annular shape, and the inner peripheral surface side is brought into close contact with the outer peripheral surface of the wire lead-out portion Wea at the tip of the wire We, and the outer peripheral surface side is brought into close contact with the inner peripheral surfaces 40c, 50c of the split tube portion 42 and the second cover member 50, respectively.
In addition, the first sealing member 71 shown here has a function for not only ensuring the liquid tightness between the electric wire We and the shield case 30, but also maintaining the electrical connection state between the shield case 30 and the electrical connection member 61. Therefore, the first seal member 71 shown here is made to abut against not only the inner peripheral surfaces 40c, 50c of the split cylinder 42 and the second cover member 50 but also the inner peripheral surface of the electric connection member 61, so that the reaction force associated with the elastic deformation itself acts on the inner peripheral surfaces 40c, 50c of the split cylinder 42 and the second cover member 50 and the inner peripheral surface of the electric connection member 61. The reaction force from the outer peripheral surface side accompanying the elastic deformation of the first seal member 71 directly acts on the inner peripheral surfaces 40c, 50c of the split cylinder 42 and the second cover member 50 from the outer peripheral surface side of the first seal member 71, and indirectly acts on the inner peripheral surfaces 40c, 50c of the split cylinder 42 and the second cover member 50 via the electric connection member 61. The outer peripheral surface of the electric connection member 61 is pressed against the inner peripheral surfaces 40c, 50c of the split cylinder 42 and the second cover member 50 by the reaction force from the outer peripheral surface side of the first seal member 71. In this way, the electric connection member 61 is interposed between the inner peripheral surface of the shield case 30 (the inner peripheral surfaces 40c, 50c of the split tube portion 42 and the second cover member 50, respectively) and the outer peripheral surface side of the first seal member 71, and can maintain the physical connection and the electric connection state with respect to the shield case 30 by the reaction force from the outer peripheral surface side of the first seal member 71.
Specifically, the first seal member 71 has a plurality of annular inner peripheral lips 71a on the inner peripheral surface side and a plurality of annular outer peripheral lips 71b on the outer peripheral surface side (fig. 9).
In the first seal member 71, all of the inner peripheral lips 71a are elastically deformed to be in close contact with the outer peripheral surface of the outer cover We 4.
On the other hand, in the first seal member 71, the outer peripheral lip 71b on the wire drawing direction side is elastically deformed to be in contact with the inner peripheral surfaces 40c, 50c of the split tube portion 42 and the second cover member 50, respectively, and the outer peripheral lip 71b on the opposite side to the wire drawing direction side is elastically deformed to be in contact with the inner peripheral surface of the second cylindrical portion 61b of the electric connection member 61. Therefore, the first seal member 71 can cause the reaction force associated with the elastic deformation of the outer peripheral lip 71b on the wire drawing direction side to act on the inner peripheral surfaces 40c, 50c of the split cylindrical portion 42 and the second cover member 50, respectively, and cause the reaction force associated with the elastic deformation of the outer peripheral lip 71b on the opposite side to the wire drawing direction side to act on the inner peripheral surface of the second cylindrical portion 61b of the electric connection member 61. The first seal member 71 applies a reaction force associated with elastic deformation of the outer peripheral lip 71b on the side opposite to the wire drawing direction to the inner peripheral surfaces 40c and 50c of the split cylinder 42 and the second cover member 50 through the second cylindrical portion 61b, thereby pressing the outer peripheral surface of the second cylindrical portion 61b against the inner peripheral surfaces 40c and 50c of the split cylinder 42 and the second cover member 50, respectively. That is, the electric connection member 61 is inserted into the second cylindrical portion 61b on the side opposite to the wire-drawing direction side of the first seal member 71, so that the second cylindrical portion 61b is interposed between the inner peripheral surface of the shield case 30 (the inner peripheral surfaces 40c, 50c of the split cylindrical portion 42 and the second cover member 50, respectively) and the outer peripheral surface side (the outer peripheral lip portion 71b on the side opposite to the wire-drawing direction side) of the first seal member 71. Therefore, in the second cylindrical portion 61b, the outer peripheral surface of the second cylindrical portion 42 and the inner peripheral surfaces 40c and 50c of the second cover member 50 can be continuously and physically connected to each other by the reaction force from the outer peripheral lip portion 71b on the side opposite to the wire drawing direction side.
The first sealing member 71 also fills the annular gap between the outer peripheral surface of the electric wire We and the inner peripheral surface of the second cylindrical portion 61b, and thus can also suppress the penetration of liquid into the inside of the electric connection member 61.
The second seal member 72 is, for example, a rubber seal member that is elastically deformable, and is disposed between the outer peripheral surface of the electric wire We and the inner peripheral surface of the housing 20 in order to prevent liquid from entering between the outer peripheral surface of the electric wire We and the inner peripheral surface of the housing 20 from the outside. In addition, the second sealing member 72 is also disposed between the outer peripheral surface of the electric connection member 61 and the inner peripheral surface of the shield case 30 in order to suppress penetration of liquid from the outside between the outer peripheral surface of the electric connection member 61 and the inner peripheral surface of the shield case 30. Accordingly, the second sealing member 72 has: a first annular portion 72a closing an annular gap between an outer peripheral surface of the electric wire We and an inner peripheral surface of the housing 20; and a second annular portion 72b (fig. 9) closing an annular gap between the outer peripheral surface of the electric connection member 61 and the inner peripheral surface of the shield case 30. The second seal member 72 has an annular connecting portion 72c (fig. 9) that coaxially connects the first annular portion 72a and the second annular portion 72 b. The second seal member 72 is coaxially disposed on the opposite side of the first seal member 71 from the wire drawing direction side.
The second sealing member 72 shown here is provided for each electric wire We. Accordingly, the first annular portion 72a, the second annular portion 72b, and the connecting portion 72c of the second seal member 72 are each formed in an annular shape. The first annular portion 72a is configured to have an inner peripheral surface side in close contact with an outer peripheral surface of the wire lead-out portion Wea at the end of the wire We, and an outer peripheral surface side in close contact with an inner peripheral surface of the wire accommodating portion 22. In this example, the inner peripheral surface side of the first annular portion 72a is brought into close contact with the outer peripheral surface of the inner cover We2 of the wire drawing portion Wea. The second annular portion 72b is configured to bring the inner peripheral surface side into close contact with the outer peripheral surface of the electrical connection member 61, and bring the outer peripheral surface side into close contact with the inner peripheral surfaces 40c and 50c of the split cylinder 42 and the second cover member 50, respectively.
Specifically, the first annular portion 72a is disposed on the opening side of the wire housing portion 22 in the wire drawing direction, and is disposed on the opposite side of the wire drawing direction side from the folded-back braid We3 and the electrical connection member 61 in the wire drawing portion Wea. The first annular portions 72a each have a plurality of annular inner peripheral lips 72a on the inner peripheral surface side 1 And an annular peripheral lip 72a on the peripheral surface side 2 (FIG. 9). In the first annular portion 72a, all of the inner peripheral lip portions 72a are made to be 1 Elastically deformed to be simultaneously adhered to the outer peripheral surface of the inner cover We2, thereby causing the whole of the outer peripheral lip portion 72a to be 2 Elastically deformed while being closely attached to the inner peripheral surface of the wire housing portion 22.
The second annular portion 72b is disposed on the opposite side of the first seal member 71 and the second cylindrical portion 61b of the electric connection member 61 from the electric wire drawing direction side, and on the electric wire drawing direction side of the first cylindrical portion 61a of the electric connection member 61. The second annular portions 72b each have a plurality of annular inner peripheral lips 72b on the inner peripheral surface side 1 And an annular peripheral lip 72b on the peripheral surface side 2 (FIG. 9). In the second annular portion 72b, allInner peripheral lip 72b of the portion 1 Elastically deformed to be simultaneously in close contact with the outer peripheral surface of the third cylindrical portion 61c of the electric connection member 61, thereby bringing all of the outer peripheral lips 72b into close contact with each other 2 Elastically deformed and simultaneously brought into close contact with the inner peripheral surfaces 40c, 50c of the divided cylinder 42 and the second cover member 50.
In this way, in the connector 1, the first seal member 71 and the second seal member 72 are arranged between the one end 50a and the other end 50b thereof when viewed from the second cover member 50. The first seal member 71 is disposed at a portion of the one end 50a of the second cover member 50 closer to the other end 50b of the second cover member 50 than the point of application of the axial force to the fixing portion 53, and elastically deforms in a compressed state in the radial direction between the outer peripheral surface of the wire We (the outer peripheral surface of the wire lead-out portion Wea) and the inner peripheral surface of the shield case 30 (the inner peripheral surfaces 40c, 50c of the split tube portion 42 and the second cover member 50, respectively). A reaction force in the radial direction accompanied by elastic deformation of the first seal member 71 acts on the inner peripheral surface 50c of the one end 50a of the second cover member 50 from the outer peripheral surface side.
Here, the shield case 30 such as the second cover member 50 is as thin as possible for the purpose of weight reduction and downsizing. Therefore, the shield case 30 may be elastically deformed by an external force. In the second cover member 50 shown here, in a state where the fastening of the male screw member B to the female screw portion 43a is completed, the point of application of the axial force to the fixing portion 53 on the one end 50a side becomes a fulcrum, and the point of application of the reaction force from the first seal member 71 to the inner peripheral surface 50c on the one end 50a side becomes a force point, so that the other end 50B side may be opposed to the portion 41a of the annular end surface 41a of the tubular portion 41 of the first cover member 40 1 And (5) tilting. In particular, in the connector 1 shown here, the second cylindrical portion 61b of the electric connection member 61 is present between the second cover member 50 and the first seal member 71 on the opposite side to the wire drawing direction side, and the elastic deformation amount on the opposite side to the wire drawing direction side is large on the outer peripheral surface side of the first seal member 71 compared to the wire drawing direction side, and therefore there is a possibility that the second cylindrical portion 61b expands to the outside in the radial direction due to a reaction force larger on the opposite side to the wire drawing direction side than the wire drawing direction side. Therefore, in the connector 1 shown here, there is also a possibility that the second The cylindrical portion 61b tilts the other end 50b side of the second cover member 50 in accordance with the deformation of the reaction force from the first seal member 71.
Accordingly, in the connector 1, the other end 50b side of the second cover member 50 is locked to the first cover member 40 by being moved relatively in response to the axial force acting on the fixing portion 53 of the second cover member 50 and the reaction force of the first seal member 71 to the inner peripheral surface 50c of the second cover member 50. Specifically, the first cover member 40 has a locking portion 45 (fig. 5, 6, and 8) for locking the relative movement of the locked portion 55 of the other end 50b of the second cover member 50.
In the first cover member 40, a part 41a of the annular end surface 41a of the tube portion 41 1 The side is provided with a locking portion 45. The second cover member 50 is provided with a locked portion 55 at the other end 50b thereof.
Specifically, the first cover member 40 has: a first outer groove 46A and a second outer groove 46B formed in a part 41a of the annular end surface 41a of the tube 41 1 A side of shifting the outer peripheral surface side of the cylindrical portion 41 of the annular end surface 41a in a direction opposite to the wire drawing direction on one side and the other side of the circumferential direction of the cylindrical portion 41 with a gap therebetween; an inner groove 46C formed in a part 41a of the annular end surface 41a of the tube 41 1 A side that deflects an inner peripheral surface of the cylindrical portion 41 of the annular end surface 41a in a direction opposite to the wire drawing direction between the one side and the other side in the circumferential direction of the cylindrical portion 41; and an outer side wall 46D disposed between the first outer side groove 46A and the second outer side groove 46B and closer to the outer peripheral surface side of the tube 41 than the inner side groove 46C (fig. 6). In the first cover member 40, the outer side wall portion 46D is used as the locking portion 45. Specifically, a wall surface on the inner groove 46C side of the outer wall 46D is used as the locking portion 45.
In addition, the second cover member 50 has: a first fitting portion 56A protruding from the outer peripheral surface side of the opposite end surface 51 of the other end 50b in a direction opposite to the wire drawing direction, and fitted into the first outer groove portion 46A in a state where the second cover member 50 is assembled to the first cover member 40; a second fitting portion 56B protruding from the outer peripheral surface side of the opposite end surface 51 of the other end 50B in a direction opposite to the wire drawing direction, and fitted into the second outside groove portion 46B in a state where the second cover member 50 is assembled to the first cover member 40; a cutout 56C formed between the first fitting portion 56A and the second fitting portion 56B, for fitting the outer side wall portion 46D of the first cover member 40 in a state where the second cover member 50 is assembled to the first cover member 40; and a third fitting portion 56D protruding from the inner peripheral surface side of the opposing end surface 51 of the other end 50b in a direction opposite to the wire drawing direction on the inner peripheral surface side of the second cover member 50 with respect to the notch 56C, and fitted into the inner groove portion 46C in a state where the second cover member 50 is assembled to the first cover member 40 (fig. 6 and 7). In the second cover member 50, the third fitting portion 56D is used as the engaged portion 55. Specifically, the wall surface on the side of the cutout 56C in the third fitting portion 56D is used as the engaged portion 55.
In this connector 1, during the screw tightening of the respective fixing portions 43, 53, the inner peripheral surface 50c of the second cover member 50 receives the reaction force from the first seal member 71 directly on the wire drawing direction side of the first seal member 71, and receives the reaction force from the first seal member 71 indirectly via the second cylindrical portion 61b on the opposite side of the first seal member 71 from the wire drawing direction side. Therefore, in the connector 1, during the screw tightening, the other end 50b side of the second cover member 50 is intended to move relatively to the first cover member 40 with the one end 50a side as a fulcrum, as the other end 50b of the second cover member 50 is tilted, but the relative movement of the engaged portion 55 at the other end 50b of the second cover member 50 is engaged by the engaging portion 45 of the first cover member 40 in the inner groove portion 46C.
In the connector 1, even in a state where the fixing of the screws to the fixing portions 43 and 53 is completed, the inner peripheral surface 50c of the second cover member 50 receives the reaction force from the first seal member 71 directly on the wire-drawing direction side of the first seal member 71, and receives the reaction force from the first seal member 71 indirectly via the second cylindrical portion 61b on the opposite side of the first seal member 71 from the wire-drawing direction side. Therefore, in the connector 1, in the state where the screw tightening is completed, the space between the first cover member 40 and the second cover member 50 is not enlarged Gap (specifically, a part 41a of the annular end surface 41a in the tube portion 41 1 A gap between the second cover member 50 and the opposite end surface 51 of the other end 50 b), the engaged portion 55 at the other end 50b of the second cover member 50 is engaged with the engaging portion 45 of the first cover member 40 in the inner groove 46C. Therefore, in the connector 1 of the present embodiment, tilting of the other end 50b of the second cover member 50 with respect to the first cover member 40, which corresponds to the axial force at the respective fixing portions 43, 53 and the reaction force from the first seal member 71 at the inner peripheral surface 50c of the second cover member 50, can be suppressed, and therefore, the liquid can be suppressed from flowing out of the gap between the first cover member 40 and the second cover member 50 (specifically, the portion 41a of the annular end surface 41a of the tube portion 41 1 A gap between the second cover member 50 and the opposite end surface 51 of the other end 50 b) is immersed, thereby improving the water-stopping performance.
The connector 1 is provided with a first outer groove 46A and a first fitting portion 56A, and a second outer groove 46B and a second fitting portion 56B, which are fitted to each other. Therefore, in the connector 1, the creepage distance between the first outer groove 46A and the first fitting portion 56A and the creepage distance between the second outer groove 46B and the second fitting portion 56B can be ensured, and the liquid can be prevented from reaching the part 41a of the annular end surface 41a of the tubular portion 41 through the gap between them 1 A gap with the opposite end surface 51 of the other end 50b of the second cover member 50. In the connector 1, the engagement function of the engagement portion 45 and the engaged portion 55 also suppresses the expansion of the gap between the first outer groove 46A and the first fitting portion 56A and the gap between the second outer groove 46B and the second fitting portion 56B, and thus the creepage distance therebetween can be maintained. Therefore, the connector 1 can further improve the water stopping performance.
Further, although the connector 1 is provided with the outer wall portion 46D and the notch 56C fitted to each other, the expansion of the gap between the outer wall portion 46D and the notch 56C can be suppressed by the locking function by the locking portion 45 and the locked portion 55, and therefore, the liquid can be suppressed from reaching the portion 41a of the annular end surface 41a of the tubular portion 41 through the gap 1 With another of the second cover parts 50Gap between the opposite end faces 51 of end 50 b. Therefore, the connector 1 can also improve the water stopping performance from this point of view.
In the connector 1, 1 of the 2 second direction locking walls 32 is provided in the second cover member 50. The second direction locking wall 32 of the second cover member 50 is provided between one end 50a and the other end 50b of the inner peripheral surface side of the second cover member 50. More specifically, the second direction locking wall 32 of the second cover member 50 is provided between the point of action of the reaction force from the first seal member 71 on the one end 50a of the second cover member 50 and the locked portion 55 of the other end 50 b. The second direction locking wall 32 is inserted into the recess 20a of the housing 20 assembled to the first cover member 40 by assembling the first cover member 40 and the second cover member 50, and is locked with the connecting wall 25 of the housing 20. Therefore, when the other end 50b of the second cover member 50 is tilted with respect to the first cover member 40 with the one end 50a side as a fulcrum, the second direction locking wall 32 may be separated from the recess 20a of the housing 20, and the connecting wall 25 of the housing 20 may not be locked. In the connector 1, the other end 50b of the second cover member 50 may be tilted and the housing 20 may be tilted from the divided cylinder 42 in the first cover member 40, and in this case, the locking function of the housing 20 by the second direction locking wall 32 of the divided cylinder 42 may not be performed. However, in this connector 1, since the locking function by the locking portion 45 and the locked portion 55 is provided, as described above, the tilting of the other end 50b of the second cover member 50 can be suppressed, and therefore, the accommodated state of the second direction locking wall 32 of the second cover member 50 with respect to the recess 20a can be maintained, and the locking function of the second direction locking wall 32 of the divided cylinder 42 can also be maintained. Therefore, the connector 1 of the present embodiment can continuously maintain the assembled state of the housing 20 and the shield case 30 while improving the water blocking performance.
