Detailed description of the preferred embodiment

[0009] An embodiment of a connector according to the present invention is described in detail below with reference to the accompanying drawings. It should be noted that this embodiment does not limit the invention. embodiment

[0010] In the following, an embodiment of the connector according to the present invention is described with reference to the Fig. 1 to 9 described.

[0011] Reference numeral 1 in the Fig. 1 to 8 designate the connector of the present embodiment. The connector 1 comprises a terminal 10, a housing 20 and a shielding sleeve 30 ( Fig. 4 and Fig. 8) The connector 1 electrically connects the terminal 10 to a mating terminal (not shown) within a cylindrical mating terminal section by inserting and fitting the terminal 10 and the housing 20 into the mating terminal (not shown). The connector 1 is inserted into and removed from the mating terminal along its cylindrical axial direction.

[0012] For example, connector 1 is electrically connected to the mating terminal of a mating connector (not shown), thereby electrically connecting the mating connector device and the device (not shown) to be connected to an electrical wire We. The mating connector device comprises a metal housing and a terminal block or mating plug (not shown), in which the mating terminal protrudes from the mating wall of the housing. The mating terminal has a cylindrical axial direction perpendicular to the flat wall surface of the mating wall and is shaped, for example, such that a cross-section perpendicular to the cylindrical axial direction forms a circular or elliptical ring shape. Connector 1 electrically connects, for example,An inverter, acting as a mating connector device mounted on a vehicle, and a lathe, acting as a device to be connected to the electrical line and also mounted on the vehicle, are connected by plugging and connecting them to the mating connector. The connector 1 shown here is attached to the wall surface of the mating body in a state in which it is mounted and connected to the mating connector.

[0013] The connector 10 is made of a conductive material, such as metal. The connector 10 has a connection section 11, which is physically and electrically connected to the mating connector, and an electrical wire connection section 12, which is physically and electrically connected to the end of the electrical wire We ( Fig. 4 and Fig. 8). The connector 10 is attached to the end of the electrical wire We.

[0014] For example, one of the connection sections 11 and the mating connection section of the mating connection are in a socket form, and the other is in a plug form. In this case, the connection section 11 is formed in a cylindrical socket form, and the mating connection section is formed in a columnar plug form to fit into the connection section 11. The electrical wire connection section 12 is physically and electrically connected to the electrical wire We, for example, by crimping or welding to a core wire We1 of the electrical wire We connection.

[0015] It should be noted that the electrical wire We shown here is a so-called shielded electrical wire and comprises a columnar, conductive core wire We1, a cylindrical inner insulating coating (inner sheath) We2 that coaxially covers the core wire We1, a cylindrical conductive braid We3 that coaxially covers the inner coating We2, and a cylindrical outer insulating coating (outer sheath) We4 that coaxially covers the braid We3. Fig. 1 and Fig. 4).

[0016] The illustrated connector 10 has a straight shape, in which the connecting section 11 and the electrical wire connecting section 12 are arranged on a straight line. Therefore, the electrical wire We can be pulled out of the electrical wire connecting section 12 along the straight line in the direction of extension of the connector 10. However, the connector 10 can be arranged such that the connecting section 11 and the electrical wire connecting section 12 intersect, for example, perpendicular to each other.

[0017] The connector 1 shown here comprises two pairs of terminals 10 and electrical conductors or wires We.

[0018] The housing 20 is cast from an insulating material, such as synthetic resin. The housing 20 contains the connector 10 and the electrical wire We. The housing 20 has the connector 10 held in a recessed position and the electrical wire We, which can be pulled out from the inside.

[0019] The housing 20 has a connection housing section 21 in which the connection piece 10 is housed and inserted into the mating connection piece ( Fig. 1 to 8). The connection housing section 21 shown here is cylindrically shaped and is inserted into and removed from the mating connection piece along the cylindrical axial direction. In the housing 20 shown here, the connection housing sections 21 are formed for each connection piece 10, and each of the connection housing sections 21 is arranged in a direction perpendicular to the cylindrical axial direction.

[0020] Furthermore, the housing 20 has an electrical wire housing section 22 in which the electrical wire We, which can be pulled out from the electrical wire housing section 12, is housed and which makes it possible for the electrical wire We to be pulled out from the interior ( Fig. 4 and 6 to 8). The electrical wire housing section 22 shown here is cylindrical and arranged coaxially with the connection housing section 21. Therefore, the electrical wire housing section 22 allows the electrical wire, which can be pulled out from the electrical wire connection section 12 from the inside out, to be pulled out in the same direction as the pulling direction. In the housing 20 shown here, the electrical wire housing sections 22 are formed for each connection piece 10, and each of the electrical wire housing sections 22 is arranged in a direction perpendicular to the cylindrical axial direction.

[0021] Furthermore, the housing 20 has an annular flange section 23 between each of the terminal housing sections 21 and each of the electrical wire housing sections 22, which projects radially outwards from each of the terminal housing sections 21 and radially outwards from each of the electrical wire housing sections 22 ( Fig. 8).

[0022] The shielding sleeve 30 is cast from a metallic material (e.g., aluminum or aluminum alloy). The housing 20 and the electrical wire We, which can be pulled out of the housing 20, are housed within the shielding sleeve 30. The electrical wire We, which can be pulled out of the electrical wire housing section 22 of the housing 20, is pulled from the inside out within the shielding sleeve 30, while the housing 20 remains in its closed position. The electrical wire We, which can be pulled out of the electrical wire housing section 22, is pulled out of the shielding sleeve 30 from the inside out in the same direction as the pulling direction.

[0023] The shielding sleeve 30 comprises a first sleeve element 40 and a second sleeve element 50, which are connected to each other ( Fig. 1 to 8).

[0024] The first sleeve element 40 shown here has a cylindrical section 41, which is formed in a cylindrical shape with the drawing direction (hereinafter referred to as the “electric wire drawing direction”) of the electric wire We as the cylindrical axial direction, and a split cylindrical section 42, which partially projects from an annular end face 41a in the direction of the electric wire drawing direction of the cylindrical section 41 by forming a section 41a1 of the annular end face 41a ( Fig. 1, 2 and 4 to 8). On the other hand, the second sleeve element 50 shown here is formed into a split cylindrical shape which, in combination with the split cylindrical section 42, forms a cylindrical shape by being assembled with the split cylindrical section 42. In other words, in the shielding sleeve 30, one of the two split cylindrical sections is the split cylindrical section 42, and the other of the two split cylindrical sections is the second sleeve element 50.

[0025] The cylindrical section 41 shown here is formed in a cylindrical shape with an elliptical, annular cross-section perpendicular to the cylindrical axial direction. The cylindrical section 41 shown here houses the flange section 23 of each of the terminal housing sections 21, the flange section 23, and the flange section 23 of each of the electrical wire housing sections 22. Therefore, the cylindrical section 41 allows each of the electrical wire housing sections 22 to project outwards from the inside on the side opposite to the direction of electrical wire extraction, and allows each of the terminal housing sections 21 to project outwards from the inside on the side opposite to the direction of electrical wire extraction.

[0026] The split cylindrical section 42 and the second sleeve element 50 can be formed in any desired shape, as long as the cylindrical shape is divided into two parts. For example, the split cylindrical section 42 and the second sleeve element 50 can be formed by uniformly dividing their cylindrical shapes into two parts, or they can be formed as a split cylindrical shape with an opening on one side and as a split cylindrical shape with a lid section that closes the opening on the other side.

[0027] The split cylindrical section 42 and the second sleeve element 50, shown here, are formed in a cylindrical shape and connected to each other, with one cross-section perpendicular to the cylindrical axial direction having an elliptical ring shape. In this case, the cylindrical shape is divided into two equal parts on one side and the other side in a short direction of an elliptical ring shape, and the split cylindrical section 42 and the second sleeve element 50 had the split cylindrical shape.The divided cylindrical section 42 and the second sleeve element 50 shown herein each contain inside the joined cylindrical form a section projecting from the cylindrical section 41 in each of the electrical wire housing parts 22 and a section Wea (hereinafter referred to as the “electrical wire draw-out section”) in each of the electrical wires We ( ) drawn out of the electrical wire housing part 22. Fig. 6 and Fig. 7) The split cylindrical section 42 and the second sleeve element 50, which are connected to each other in a cylindrical form, draw the electrical wire We out of the openings of one end 40a and 50a on the side of the electrical wire drawing direction ( Fig. 1).

[0028] Furthermore, the second sleeve element 50 shown here has an end face 51 facing the other end 50b on the side opposite the side of the electrical wire drawing direction, which is arranged such that it faces the section 41a1 of the annular end face 41a in the cylindrical section 41 on the side of the electrical wire drawing direction in order to prevent the ingress of liquid, such as water or salt water, from a gap with the cylindrical section 41 in the state in which it is assembled with the split cylindrical section 42 ( Fig. 4, Fig. 5 and Fig. 7) Therefore, the connector 1 narrows the gap between the section 41a1 of the annular end face 41a of the cylindrical section 41 and the opposite end face 51 of the other end 50b of the second sleeve element 50 as much as possible within an area in which the first sleeve element 40 and the second sleeve element 50 can be assembled.

[0029] Furthermore, partition walls 42a and 52 protrude from the inner circumferential surfaces of the divided cylindrical section 42 and the second sleeve element 50 shown here, which are arranged between the electrical wire drawing sections Wea in order to prevent contact between the electrical wire drawing sections Wea within the cylindrical shape ( Fig. 5, Fig. 6 and Fig. 8) The split cylindrical section 42 and the second sleeve element 50 have two semicircular inner circumferential surfaces 40c and 50c with the same diameter, which are formed by the partitions 42a and 52 respectively ( Fig. 4, Fig. 6 and Fig. 8) The split cylindrical section 42 and the second sleeve element 50 have two column-shaped chambers formed in the assembled cylindrical shape, and the electrical wire drawing section Wea is arranged in each of the chambers. Each of the partitions 42a and 52 shown here has a flat upper surface formed at the apex on the side of the projection direction of at least one end 40a and 50a on the side of the electrical wire drawing direction, and the upper surfaces are arranged such that they face each other in a cylindrical state in which the split cylindrical section 42 and the second sleeve element 50 are assembled.

[0030] The combined first sleeve element 40 and the second sleeve element 50 are screwed together by an axial force in a direction perpendicular to the electrical wire drawing direction at the fastening sections 43 and 53, which are formed at one end 40a and 50a on the side of the electrical wire drawing direction ( Fig. 4 and Fig. 8) Therefore, the first sleeve element 40 is formed with the fastening section 43 at one end 40a of the split cylindrical section 42 on the side of the electrical wire drawing direction. The second sleeve element 50 is formed with the fastening section 53 at one end 50a on the side of the electrical wire drawing direction.

[0031] The shielding sleeve 30 shown here is formed with the fastening section 43 of the first sleeve element 40 at one end 40a of the partition 42a on the side of the electrical wire pulling direction and the fastening section 53 of the second sleeve element 50 at one end 50a of the partition 52 on the side of the electrical wire pulling direction. In particular, the fastening section 43 of the first sleeve element 40 comprises a female screw section 43a for screwing a male screw section B1 of a male screw element B ( Fig. 5 and Fig. 8) The female screw section 43a has a hole axis direction that runs perpendicular to the upper surface of one end 40a of the partition 42a on the side of the electrical wire pulling direction. The fastening section 53 of the second sleeve element 50 has a through hole 53a through which the male screw section B1 is inserted ( Fig. 5 and Fig. 8) The through-hole 53a has a hole axis direction perpendicular to the upper surface of one end 50a of the partition 52 on the side of the electrical wire pulling direction. The fastening sections 43 and 53 are fixed by an axial force generated by screwing together the male screw section B1 of the male screw element B and the female screw section 43a. The fastening section 53 of the second sleeve element 50 receives an axial force from a bearing surface B2 of the male screw element B, and the section on which the axial force acts serves as a point where the axial force is applied.

[0032] Furthermore, the shielding sleeve 30 is formed on its inner circumferential surface side with a locking wall 31 in a first direction for locking a relative movement of the housing 20 at the housing end position in the direction of the electrical wire drawing and a locking wall 32 in a second direction for locking a relative movement of the housing 20 at the housing end position in a direction opposite to the direction of the electrical wire drawing ( Fig. 5).

[0033] The locking wall 31 in the first direction is formed at least on the first sleeve element 40. The locking wall 31 in the first direction shown here is formed on the inner circumferential surface of the cylindrical section 41 of the first sleeve element 40. In this case, a wall surface that projects inwards from the inner circumferential surface of the cylindrical section 41 and points in the direction opposite to the electrical wire drawing direction is used as the locking wall 31 in the first direction. The cylindrical section 41 shown here has an annular wall surface 41b, which is a wall surface that points in the direction opposite to the electrical wire drawing direction and which is annularly formed along the circumferential direction of the inner circumferential surface. Fig. 5) The cylindrical section 41 uses the annular wall surface 41b as the first-direction locking wall 31. The first-direction locking wall 31 is positioned such that it faces the flange section 23 of the housing 20 on the side of the electrical wire pull direction when the housing 20 is in the housing closure position within the shielding sleeve 30. The first-direction locking wall 31 locks the flange section 23 to hold the housing 20 in the housing closure position while allowing the relative amount of play when the housing 20 is moved relative to the side of the electrical wire pull direction with respect to the shielding sleeve 30.Therefore, the flange section 23 is used as a first-direction interlocked wall, which is interlocked with the first-direction interlocking wall 31 to prevent relative movement of the housing 20 at the housing end position in the electrical wire pulling direction.

[0034] The locking wall 32 in the second direction is formed on both the first sleeve element 40 and the second sleeve element 50. The locking wall 32 shown here in the second direction is formed on the inner circumferential surface of the split cylindrical section 42 of the first sleeve element 40 and between one end 50a and the other end 50b on the inner circumferential surface of the second sleeve element 50.

[0035] The divided cylindrical section 42 has a recessed section 42b, which is recessed with its inner circumferential surface on the side opposite the side of the electrical wire drawing direction, instead of the partition 42a, and a wall surface 42c in the recessed section 42b on the side opposite the side of the electrical wire drawing direction, which projects from the inner circumferential surface ( Fig. 5) The split cylindrical section 42 uses the wall surface 42c as the locking wall 32 in the second direction. On the other hand, the housing 20 has an elastically deformable part 24A, which has a free end on the side of the electrical wire drawing direction and a fixed end on the side opposite the electrical wire drawing direction, and a claw 24B formed at the free end of part 24A ( Fig. 5) Part 24A projects between the electrical wire housing sections 22 into the flange section 23 and is elastically deformed in a direction perpendicular to the electrical wire drawing direction and to an arrangement direction of each electrical wire housing section 22. The claw 24B projects from the free end of part 24A such that it faces the inner circumferential surface of the split cylindrical section 42 when the housing 20 is in the housing closure position.

[0036] On the inside of the shielding sleeve 30, the claw 24B is housed in the recessed section 42b when the housing 20 is in the housing closure position. The locking wall 32 in the second direction of the first sleeve element 40 locks the claw 24B to hold the housing 20 in the housing closure position while allowing the relative amount of play when the housing 20 is moved relative to the shielding sleeve 30 to the side opposite the side with the electrical wire pull direction. Therefore, the claw 24B is used as a second-direction locking wall that engages with the locking wall 32 in the second direction of the first sleeve element 40 to prevent relative movement of the housing 20 in the housing closure position in the direction opposite to the electrical wire pull direction.

[0037] On the other hand, the second sleeve element 50 has a projection 54 which is shaped such that it projects from the inner circumferential surface on the side opposite the side of the electrical wire drawing direction and not on the partition wall 52, and uses the wall surface of the projection 54 on the side of the electrical wire drawing direction as the locking wall 32 in the second direction ( Fig. 5) On the other hand, the housing 20 has a connecting wall 25 which is designed to connect the outer circumferential surfaces of the electrical wire housing sections 22 at one end on the side of the electrical wire drawing direction and to fill one end on the side of the electrical wire drawing direction in a recess 20a between the respective electrical wire housing sections 22 ( Fig. 5 and Fig. 8) On the inside of the shielding sleeve 30, the projection 54 is accommodated in the recess 20a when the housing 20 is in the housing closure position. The locking wall 32 in the second direction 2 of the second sleeve element 50 locks the connecting wall 25 to hold the housing 20 in the housing closure position while allowing the relative amount of play when the housing 20 is moved relative to the shielding sleeve 30 to the side opposite the side with the electrical wire pull direction. Therefore, the connecting wall 25 is used as a second-direction locking wall that engages with the locking wall 32 in the second direction of the second sleeve element 50 to prevent relative movement of the housing 20 in the housing closure position in the direction opposite to the electrical wire pull direction.

[0038] The connector 1 fixes the shielding sleeve 30 to the wall surface of the counter wall body in a state where it is connected to the mating connector. The shielding sleeve 30 secures the other end 40b of the first sleeve element 40 to the wall surface of the counter wall body on the side opposite the electrical wire pulling direction side ( Fig. 1 and Fig. 2) Therefore, the first sleeve element 40 has an annular flange section 44 at the other end 40b of the cylindrical section 41, which projects outwards from the outer circumferential surface of the cylindrical section 41 ( Fig. 1 and Fig. 2) The flange section 44 is attached to the wall surface of the counter wall body by a screw element.

[0039] The connector 1 also includes an electrical connecting element 61 for electrically connecting the shielding sleeve 30 to the braid We3 of the electrical wire We ( Fig. 4 and 6 to 9). The electrical connecting element 61 is made of a conductive material, such as metal. The electrical connecting element 61 shown here is designed for each electrical wire We. Furthermore, the electrical connecting element 61 shown here is cylindrical and concentrically covers the interior of the electrical wire drawing section Wea.

[0040] In this case, at the end of the electrical wire We, the outer coating We4 is peeled off from the tip to the nearer side of the electrical wire drawing section Wea, and the braid We3 on the tip side, and not on the nearer side, of the electrical wire drawing section Wea is folded back into a cylindrical shape to cover the outer circumferential surface of the outer coating We4. The electrical connecting element 61 has a first column-shaped section 61a that concentrically covers the folded section of the braid We3 from the outside ( Fig. 4 and Fig. 9) The first columnar section 61a is concentrically covered from the outside by a cylindrical fastening element 62. The fastening element 62 is, for example, a so-called crimping ring, which is formed from a conductive material such as metal and physically and electrically connects the first columnar section 61a to the folded section of the braid We3 by crimping and crimping it to the first columnar section 61a.

[0041] Furthermore, the electrical connecting element 61 has a second column-shaped section 61b, which is coaxial with the first column-shaped section 61a and whose outer circumferential surface is in contact with the inner circumferential surface side of the shielding sleeve 30 ( Fig. 4 and Fig. 9) The outer circumferential surface of the second columnar section 61b is physically and electrically connected to the semicircular inner circumferential surfaces 40c and 50c of the split cylindrical section 42 and the second sleeve element 50, respectively. Therefore, the second columnar section 61b is designed such that it has an outer circumferential surface with a radius equal to the inner circumferential surfaces 40c and 50c of the split cylindrical section 42 and the second sleeve element 50, respectively. In other words, the second columnar section 61b is shaped to have a larger diameter than the first columnar section 61a.

[0042] The electrical connecting element 61 also has a third column-shaped section 61c with a diameter that is larger than that of the first column-shaped section 61a and smaller than that of the second column-shaped section 61b, which is formed between the first column-shaped section 61a and the second column-shaped section 61b and is coaxial with the first column-shaped section 61a and the second column-shaped section 61b ( Fig. 4).

[0043] The connector 1 has a first sealing element 71 for filling the gap between the electrical wire We and the shielding sleeve 30 so that the liquid entering from the outside does not enter the connector 10 ( Fig. 4 and 6 to 9). The connector 1 also includes a second sealing element 72 for filling the gap between the electrical wire We and the housing 20, which is arranged inside the first sealing element 71 to improve the liquid tightness ( Fig. 4 and 6 to 9).

[0044] The first sealing element 71 is, for example, an elastically deformable rubber sealing element and is arranged between the outer circumferential surface of the electrical conductor We and the inner circumferential surface of the shielding sleeve 30 to prevent the ingress of liquid from the outside. The first sealing element 71 is annular in shape to close an annular gap between the outer circumferential surface of the electrical conductor We and the inner circumferential surface of the shielding sleeve 30. The first sealing element 71 is arranged at one end 40a and 50a of the first sleeve element 40 and the second sleeve element 50 on the side of the other ends 40b and 50b of the first sleeve element 40 and the second sleeve element 50, and not at the point where the axial force is exerted on the fastening sections 43 and 53. Fig. 4).

[0045] The first sealing element 71 shown here is designed for each electrical wire We. Therefore, the first sealing element 71 is ring-shaped, brings its inner circumferential surface into close contact with the outer circumferential surface of the electrical wire drawing part Wea at the end of the electrical wire We, and brings its outer circumferential surface into close contact with the inner circumferential surfaces 40c and 50c of the split cylindrical section 42 and the second sleeve element 50.

[0046] Furthermore, the first sealing element 71 shown here not only serves to ensure liquid tightness between the electrical wire We and the shielding sleeve 30, but also to maintain an electrical connection between the shielding sleeve 30 and the electrical connecting element 61. Therefore, the outer circumferential surface of the first sealing element 71 shown here comes into close contact not only with the inner circumferential surfaces 40c and 50c of the split cylindrical section 42 and the second sleeve element 50, but also with the inner circumferential surface of the electrical connecting element 61, so that the reaction force caused by its own elastic deformation acts on the inner circumferential surfaces 40c and 50c of the split cylindrical section 42 and the second sleeve element 50, as well as on the inner circumferential surface of the electrical connecting element 61.The reaction force from the outer circumferential surface, caused by the elastic deformation of the first sealing element 71, acts directly on the inner circumferential surfaces 40c and 50c of the split cylindrical section 42 and the second sleeve element 50 from the outer circumferential surface of the first sealing element 71 and acts indirectly via the electrical connecting element 61. The outer circumferential surface of the electrical connecting element 61 is pressed against the inner circumferential surfaces 40c and 50c of the split cylindrical section 42 and the second sleeve element 50 by utilizing the reaction force from the outer circumferential surface of the first sealing element 71.Thus, the electrical connecting element 61 is arranged between the inner circumferential surface (inner circumferential surfaces 40c and 50c of the split cylindrical section 42 and the second sleeve element 50) of the shielding sleeve 30 and the outer circumferential surface side of the first sealing element 71 and maintains the physical and electrical connection with the shielding sleeve 30 by receiving the reaction force from the outer circumferential surface side of the first sealing element 71.

[0047] In particular, the first sealing element 71 has a plurality of annular inner circumferential lips 71a on its inner circumferential surface side and a plurality of annular outer circumferential lips 71b on its outer circumferential surface side ( Fig. 9).

[0048] The first sealing element 71 brings all inner circumferential lips 71a into close contact with the outer circumferential surface of the outer coating We4 and thereby elastically deforms the inner circumferential lips.

[0049] On the other hand, the first sealing element 71 brings the outer circumferential lip 71b on the side of the electrical wire drawing direction into close contact with the inner circumferential surfaces 40c and 50c of the split cylindrical section 42 and the second sleeve element 50, while elastically deforming the outer circumferential lip, and brings the outer circumferential lip 71b on the side opposite the side of the electrical wire drawing direction into close contact with the inner circumferential surface of the second column-shaped section 61b of the electrical connecting element 61, while elastically deforming the outer circumferential lip.Therefore, the first sealing element 71 causes a reaction force, caused by the elastic deformation of the outer circumferential lip 71b on the side of the electrical wire drawing direction, to act on the inner circumferential surfaces 40c and 50c of the split cylindrical section 42 and the second sleeve element 50, and causes a reaction force, caused by the elastic deformation of the outer circumferential lip 71b on the side opposite the side of the electrical wire drawing direction, to act on the inner circumferential surface of the second column-shaped section 61b of the electrical connecting element 61.The first sealing element 71 presses the outer circumferential surface of the second column-shaped section 61b against the inner circumferential surfaces 40c and 50c of the split cylindrical section 42 and the second sleeve element 50 by causing a reaction force, generated by the elastic deformation of the outer circumferential lip 71b on the side opposite to the side of the electrical wire drawing direction, to act via the second column-shaped section 61b on the inner circumferential surfaces 40c and 50c of the split cylindrical section 42 and the second sleeve element 50.In other words, the electrical connecting element 61 inserts the side opposite the side of the electrical wire drawing direction in the first sealing element 71 into the second columnar section 61b, such that the second columnar section 61b is positioned between the inner circumferential surfaces (inner circumferential surfaces 40c and 50c of the split cylindrical section 42 and the second sleeve element 50) of the shielding sleeve 30 and the outer circumferential surface (outer circumferential lip 71b on the side opposite the side of the electrical wire drawing direction) of the first sealing element 71. Therefore, the second columnar section 61b can utilize a reaction force from the outer circumferential lip 71b on the side opposite the side of the electrical wire drawing direction and maintain its outer circumferential surface physically and electrically connected to the inner circumferential surfaces 40c and 50c of the split cylindrical section 42 and the second sleeve element 50.

[0050] Since the first sealing element 71 also fills an annular gap between the outer circumferential surface of the electrical wire We and the inner circumferential surface of the second column-shaped section 61b, the first sealing element can prevent the ingress of liquid into the interior of the electrical connecting element 61.

[0051] The second sealing element 72 is, for example, an elastically deformable rubber sealing element and is arranged between the outer circumferential surface of the electrical wire We and the inner circumferential surface of the housing 20 to prevent the ingress of liquid from the outside. The second sealing element 72 is also arranged between the outer circumferential surface of the electrical connecting element 61 and the inner circumferential surface of the shielding sleeve 30 to prevent the ingress of liquid from the outside. Therefore, the second sealing element 72 has a first annular section 72a for closing an annular gap between the outer circumferential surface of the electrical wire and the inner circumferential surface of the housing 20, and a second annular section 72b for closing an annular gap between the outer circumferential surface of the electrical connecting element 61 and the inner circumferential surface of the shielding sleeve 30. Fig. 9) The second sealing element 72 has an annular connecting section 72c that coaxially connects the first annular section 72a and the second annular section 72b ( Fig. 9) The second sealing element 72 is coaxial with the first sealing element 71 and is arranged on the side opposite the side with the direction of electrical wire pull.

[0052] The second sealing element 72 shown here is designed for each electrical conductor We. Therefore, the second sealing element 72 has the first annular section 72a, the second annular section 72b, and the connecting section 72c, each of which is annular in shape. The first annular section 72a brings its inner circumferential surface into close contact with the outer circumferential surface of the electrical wire drawing section Wea at the end of the electrical wire We and brings its outer circumferential surface into close contact with the inner circumferential surface of the electrical wire housing section 22. In the illustrated example, the inner circumferential surface of the first annular section 72a is brought into close contact with the outer circumferential surface of the inner coating We2 of the electrical wire drawing section Wea.Furthermore, the second annular section 72b brings its inner circumferential surface into close contact with the outer circumferential surface of the electrical connecting element 61 and brings its outer circumferential surface into close contact with the inner circumferential surfaces 40c and 50c of the split cylindrical section 42 and the second sleeve element 50.

[0053] In particular, the first annular section 72a is located on the opening side of the electrical wire housing section 22 in the direction of the electrical wire drawing and on the side of the electrical wire drawing section Wea opposite to the direction of the electrical wire drawing, and not on the folded braid We3 and the electrical connecting element 61. The first annular section 72a has a plurality of annular inner circumferential lips 72a1 on its inner circumferential surface and a plurality of annular outer circumferential lips 72a2 on its outer circumferential surface. Fig. 9) The first annular section 72a brings all inner circumferential lips 72a1 into close contact with the outer circumferential surface of the inner coating We2 while elastically deforming the inner circumferential lips, and brings all outer circumferential lips 72a2 into close contact with the inner circumferential surface of the electrical wire housing section 22 while elastically deforming the outer circumferential lips.

[0054] The second annular section 72b is arranged on the side opposite the direction of electrical wire drawing, and not on the first sealing element 71 and the second columnar section 61b of the electrical connecting element 61, and on the side of the direction of electrical wire drawing, and not on the first columnar section 61a of the electrical connecting element 61. The second annular section 72b has a plurality of annular inner circumferential lips 72b1 on its inner circumferential surface side and a plurality of annular outer circumferential lips 72b2 on its outer circumferential surface side ( Fig. 9) The second annular section 72b brings all inner circumferential lips 72b1 into close contact with the outer circumferential surface of the third column-shaped section 61c of the electrical connecting element 61, while elastically deforming the inner circumferential lips, and brings all outer circumferential lips 72b2 into close contact with the inner circumferential surfaces 40c and 50c of the split cylindrical section 42 and the second sleeve element 50, while elastically deforming the outer circumferential lips.

[0055] As described above, the connector 1 has the first sealing element 71 and the second sealing element 72, which are arranged between one end 50a and the other end 50b, as seen from the second sleeve element 50. The first sealing element 71 is located at one end 50a of the second sleeve element 50 on the side of the other end 50b of the second sleeve element 50 and not at the point where the axial force is exerted on the fastening section 53, and is elastically deformed in a compressed state in the radial direction between the outer circumferential surface (outer circumferential surface of the electrical wire drawing section Wea) of the electrical wire We and the inner circumferential surface (inner circumferential surfaces 40c and 50c of the split cylindrical section 42 and the second sleeve element 50) of the shielding sleeve 30.The inner circumferential surface 50c of one end 50a of the second sleeve element 50 is subject to a radially outward directed reaction force caused by the elastic deformation of the first sealing element 71 from the outer circumferential surface side of the first sealing element 71.

[0056] In this case, the shielding sleeve 30, like the second sleeve element 50, is made as thin as possible to reduce weight and size. Therefore, the shielding sleeve 30 can be elastically deformed by absorbing an external force. In the second sleeve element 50 shown here, the point where the axial force is applied to the fastening section 53 on one end face 50a becomes a pivot point, and the point where the reaction force from the first sealing element 71 is applied to the inner circumferential surface 50c on one end face 50a becomes a force point, so that the other side of the end 50b can potentially be raised relative to section 41a1 of the annular end face 41a in the cylindrical section 41 of the first sleeve element 40 in a state where the male screw element B is attached to the female screw section 43a.In particular, in the connector 1 shown here, since the second column-shaped section 61b of the electrical connecting element 61 is arranged between the second sleeve element 50 and the side opposite the electrical wire drawing direction of the first sealing element 71, and the elastic deformation amount on the side opposite the side with the electrical wire drawing direction is greater than that of the side with the electrical wire drawing direction of the outer circumferential surface of the first sealing element 71, the second column-shaped section 61b may be pushed outwards in the radial direction and expanded by a reaction force on the side opposite the side with the electrical wire drawing direction that is greater than that on the side with the electrical wire drawing direction.Therefore, the connector 1 shown here may possibly lift the other end 50b of the second sleeve element 50 by deformation of the second column-shaped section 61b, which is generated by a reaction force from the first sealing element 71.

[0057] Therefore, the connector 1 locks the relative movement of the other end 50b of the second sleeve element 50 with respect to the first sleeve element 40 in accordance with the axial force on the fastening section 53 of the second sleeve element 50 and the reaction force from the first sealing element 71 on the inner circumferential surface 50c of the second sleeve element 50. In particular, the first sleeve element 40 has a locking section 45 for locking the relative movement of a locked section 55 of the other end 50b of the second sleeve element 50 ( Fig. 5, Fig. 6 and Fig. 8).

[0058] The first sleeve element 40 is formed with a locking section 45 on the side of section 41a1 of the annular end face 41a of the cylindrical section 41. Furthermore, the second sleeve element 50 is formed with the locked section 55 at the other end 50b.

[0059] In particular, the first sleeve element 40 comprises a first outer groove section 46A and a second outer groove section 46B, which are formed by offsetting the outer circumferential surface side of the cylindrical section 41 in the annular end face 41a in the direction opposite to the electrical wire drawing direction, wherein the first outer groove section 46A and the second outer groove section 46B are arranged on one side and the other side in the circumferential direction of the cylindrical section 41 and are spaced apart from each other on the side of section 41a1 of the annular end face 41a in the cylindrical section 41;an inner groove section 46C, which is formed by offsetting the inner circumferential surface side of the cylindrical section 41 in the annular end face 41a between one side and the other side in the circumferential direction of the cylindrical section 41 on the side of section 41a1 of the annular end face 41a in the cylindrical section 41 in the direction opposite to the electrical wire drawing direction; and an outer wall section 46D, which is arranged between the first outer groove section 46A and the second outer groove section 46B and on the outer circumferential surface side of the cylindrical section 41 and not on the inner groove section 46C (; Fig. 6) The first sleeve element 40 uses the outer wall section 46D as the locking section 45. In particular, the wall surface of the outer wall section 46D on the side of the inner groove section 46C is used as the locking section 45.

[0060] Furthermore, the second sleeve element 50 comprises a first fitting section 56A, which projects in a direction opposite to the direction of the electrical wire drawing from the outer circumferential surface side in the facing end face 51 of the other end 50b and is fitted into the first outer groove section 46A in a state in which it is mounted on the first sleeve element 40; a second fitting section 56B, which projects in a direction opposite to the direction of the electrical wire drawing from the outer circumferential surface side in the facing end face 51 of the other end 50b and is fitted into the second outer groove section 46B in a state in which it is mounted on the first sleeve element 40; a cutout 56C formed between the first fitting section 56A and the second fitting section 56B, and fitted into the outer wall section 46D of the first sleeve element 40 in a state in which it is mounted to the first sleeve element 40;and a third fitting section 56D, which projects in a direction opposite to the electrical wire drawing direction from the inner circumferential surface side in the facing end face 51 of the other end 50b on the inner circumferential surface side of the second sleeve element rather than the cutout 56C and is fitted into the inner groove section 46C in a state in which it is mounted to the first sleeve element 40 (; Fig. 6 and Fig. 7) The second sleeve element 50 uses the third fitting section 56D as the locked section 55. In particular, the wall surface of the third fitting section 56D on the side of the cutout 56C is used as the locked section 55.

[0061] In the connector 1, the inner circumferential surface 50c of the second sleeve element 50 receives, while the fastening sections 43 and 53 are screwed together, a reaction force from the first sealing element 71 directly on the side of the electrical wire pulling direction in the first sealing element 71 and indirectly via the second column-shaped section 61b on the side opposite the side of the electrical wire pulling direction in the first sealing element 71. Therefore, although the other end 50b of the second sleeve element 50 is moved relative to the first sleeve element 40 with the side of one end 50a as the pivot point in order to raise the other end 50b of the second sleeve element 50 during the screwing of the connector 1, the relative movement of the locked section 55 at the other end 50b of the second sleeve element 50 is locked by the locking section 45 of the first sleeve element 40 in the inner groove section 46C.

[0062] In the connector 1, the inner circumferential surface 50c of the second sleeve element 50 receives, even when the screwing with the fastening sections 43 and 53 is completed, a reaction force from the first sealing element 71 directly on the side of the electrical wire pulling direction in the first sealing element 71 and indirectly via the second column-shaped section 61b on the side opposite the side of the electrical wire pulling direction in the first sealing element 71.Therefore, in the connector 1, the relative movement of the locked section 55 at the other end 50b of the second sleeve element 50 is locked by the locking section 45 of the first sleeve element 40 in the inner groove section 46C within a region in which the gap (in particular the gap between the section 41a1 of the annular end face 41a in the cylindrical section 41 and the facing end face 51 of the other end 50b of the second sleeve element 50) between the first sleeve element 40 and the second sleeve element 50 is not widened when the screwing is completed.Thus, the connector 1 of the present embodiment prevents the other end 50b of the second sleeve element 50 from lifting off in relation to the first sleeve element 40 in accordance with the axial force at the fastening sections 43 and 53 and the reaction force from the first sealing element 71 on the inner circumferential surface 50c of the second sleeve element 50, so that the connector can prevent the ingress of liquid from the gap (in particular the gap between the section 41a1 of the annular end face 41a of the cylindrical section 41 and the opposite end face 51 of the other end 50b of the second sleeve element 50) between the first sleeve element 40 and the second sleeve element 50 and improve the water barrier performance.

[0063] Furthermore, the connector 1 is configured with a first outer groove section 46A and a first inset section 56A, which are fitted to each other, and a second outer groove section 46B and a second inset section 56B, which are fitted to each other. Therefore, the connector 1 can ensure the creepage distance between the first outer groove section 46A and the first inset section 56A and the creepage distance between the second outer groove section 46B and the second inset section 56B, in order to prevent fluid from reaching the gap between the groove sections and the inset sections through the gap between the section 41a1 of the annular end face 41a of the cylindrical section 41 and the opposite end face 51 of the other end 50b of the second sleeve element 50.The connector 1 prevents the gap between the first outer groove section 46A and the first inset section 56A, and the gap between the second outer groove section 46B and the second inset section 56B, from widening due to the interlocking function of the interlocking section 45 and the interlocked section 55. This maintains the creepage distance between the groove sections and the inset sections, thus further improving the watertightness.

[0064] Furthermore, although the connector 1 is formed with the outer wall section 46D and the cutout 56C which are fitted to each other, the locking function of the locking section 45 and the locked section 55 prevents an expansion of the gap between the outer wall section 46D and the cutout 56C, and thus prevents liquid from reaching the gap between section 41a1 of the annular end face 41a of the cylindrical section 41 and the opposite end face 51 of the other end 50b of the second sleeve element 50. Thus, the connector 1 can also improve the watertight performance in this respect.

[0065] The connector 1 is formed with one of the two locking walls 32 in the second direction on the second sleeve element 50. The locking wall 32 in the second direction of the second sleeve element 50 is formed between one end 50a and the other end 50b on the inner circumferential surface of the second sleeve element 50. More precisely, the locking wall 32 in the second direction of the second sleeve element 50 is formed between the point of application of the reaction force by the first sealing element 71 at one end 50a and the locked section 55 at the other end 50b in the second sleeve element 50.The locking wall 32 in the second direction is inserted into a recess 20a of the housing 20, which is assembled by assembling the first sleeve element 40 and the second sleeve element 50 with the first sleeve element 40, and is in a state in which it can lock between the connecting wall 25 of the housing 20. Therefore, if the other end 50b of the second sleeve element 50 is raised relative to the first sleeve element 40 with one end 50a as a pivot point, the locking wall 32 in the second direction can come out of the recess 20a of the housing 20 and no longer lock the connecting wall 25 of the housing 20.In connector 1, if the other end 50b of the second sleeve element 50 is lifted, the housing 20 can also be lifted by the split cylindrical section 42 of the first sleeve element 40. In this case, the locking function of the housing 20 by the locking wall 32 in the second direction of the split cylindrical section 42 cannot function. However, connector 1 is designed with the locking function of the locking section 45 and the locked section 55, so that lifting of the other end 50b of the second sleeve element 50 as described above can be prevented. Thus, the locking wall 32 of the second direction of the second sleeve element 50 can remain in the recess 20a, and the locking function by the locking wall 32 of the second direction of the split cylindrical section 42 can be maintained.Thus, the connector 1 of the present embodiment can maintain the assembled state of the housing 20 and the shielding sleeve 30 while simultaneously improving the water barrier performance.

[0066] In the connector according to the embodiment, the inner circumferential surface of the second sleeve element is subjected to a reaction force from the sealing element when the screw connection with each fastening section is completed. Therefore, the connector locks the relative movement of a locking section at the other end of the second sleeve element by a locking section of a first sleeve element within a region where the gap between the first sleeve element and the second sleeve element does not widen.The connector according to the embodiment prevents the lifting of the other end of the second sleeve element relative to the first sleeve element in accordance with the axial force at the fastening sections and the reaction force of the sealing element on the inner circumferential surface of the second sleeve element, so that the connector can prevent the ingress of liquid from the gap between the first sleeve element and the second sleeve element and improve the water barrier performance.
