[0009] [Description of Embodiments of the Present Invention] First, embodiments of the present invention will be listed and described. The connector of the present invention [1] is fixed to a plurality of electric wires having a core wire and an insulating coating portion, and the connector includes: terminals connected to the core wires; a resin housing covering the core wires and the terminals; a metal shell covering the resin housing and having a fixing hole for fixing to an external grounding member; and a rubber plug for preventing liquid from entering along the insulating coating portion, the rubber plug being interposed between the insulating coating portion and the metal shell, and the fixing hole being provided between the plurality of electric wires in the width direction in which the plurality of electric wires are arranged side by side.

[0010] According to this structure, since the rubber plug is interposed between the insulating coating portion and the metal shell, for example, compared with a rubber plug interposed between the insulating coating portion and the resin housing, miniaturization in the width direction of the connector can be achieved. That is, in a structure where the rubber plug is, for example, interposed between the insulating coating portion and the resin housing, the width direction of the connector is enlarged due to the arrangement of the rubber plug, the resin housing, and the metal shell in the width direction, but this situation can be avoided. In addition, since the fixing hole is provided between the plurality of electric wires in the width direction, miniaturization in the width direction of the connector can be achieved. That is, in a structure where the fixing hole is provided, for example, in a fixing portion protruding outward in the width direction of the metal shell, the width direction of the connector is enlarged, but this situation can be avoided.

[0011] [2]In [1] above, it is also possible that the core wire has a flat connecting portion that protrudes from the insulation coating portion and has a shape that is flatter than the inside of the insulation coating portion. The flat connecting portions are arranged such that the thin-wall direction of the flat connecting portion is along the width direction, and the fixing holes are provided between the flat connecting portions.

[0012] According to this structure, the core wire has flat connecting portions, which are arranged such that the thin-wall direction of the flat connecting portion is along the width direction, and the fixing holes are provided between the flat connecting portions. Therefore, miniaturization in the width direction of the connector can be achieved. That is, by arranging the flat connecting portions such that the thin-wall direction is along the width direction, a relatively large space can be ensured between the flat connecting portions. Thus, for example, the fixing holes can be provided between multiple electric wires without increasing the interval between the multiple electric wires. Therefore, miniaturization in the width direction of the connector can be achieved.

[0013] [3]In [2] above, it is also possible that the terminal has a plate-shaped terminal connecting portion, which is fixed to the flat connecting portion by welding. According to this structure, the terminal has a plate-shaped terminal connecting portion, which is fixed to the flat connecting portion by welding. Therefore, for example, compared with a case where there is no plate-shaped terminal connecting portion and fixation is achieved by crimping or the like, miniaturization in the width direction of the connector can be achieved.

[0014] [4]In [2] above or [3] above, it is also possible that the resin housing has a pair of narrowing wall portions at a position where the flat connecting portion is clamped in the width direction. As the pair of narrowing wall portions approach the tip direction of the core wire, the interval in the width direction gradually decreases.

[0015] According to this structure, the resin housing has a pair of narrowing wall portions at a position where the flat connecting portion is clamped. As the pair of narrowing wall portions approach the tip direction of the core wire, the interval in the width direction gradually decreases. Therefore, miniaturization in the width direction of the resin housing can be achieved. That is, the dimension in the width direction of the flat connecting portion is smaller than that of the portion of the insulation coating portion. Therefore, miniaturization in the width direction of the resin housing can be achieved according to their dimensions. Therefore, miniaturization in the width direction of the connector can be achieved.

[0016] [5]In any one of [1] to [4] above, it is also possible that the resin housing has a pair of terminal coating wall portions at a position where the terminal is clamped in the width direction, and the interval between the inner surfaces of the pair of terminal coating wall portions is smaller than the diameter of the insulation coating portion.

[0017] According to this structure, the resin housing has a pair of terminal covering wall portions at positions where the terminals are clamped in the width direction. The distance between the inner surfaces of the pair of terminal covering wall portions is smaller than the diameter of the insulating covering portion. Therefore, miniaturization in the width direction of the resin housing at positions corresponding to the terminals can be achieved. As a result, miniaturization in the width direction of the connector can be achieved. That is, in the structure where the insulating covering portion can also be accommodated in the portion where the distance between the inner surfaces of the pair of terminal covering wall portions is located, the useless space between the pair of terminal covering wall portions becomes larger, but this situation can be avoided.

[0018] [Details of Embodiments of the Present Invention] Specific examples of the connector of the present invention will be described below with reference to the drawings. In each drawing, for convenience of explanation, a part of the structure may be enlarged or simplified. In addition, the dimensional ratios of the respective parts may be different in each drawing. In this specification, "parallel", "orthogonal", and "perfect circle" include not only the cases that are strictly parallel, orthogonal, and perfect circle, but also the cases that are substantially parallel, orthogonal, and perfect circle within the range where the effects of the present embodiment are achieved. In addition, the present invention is not limited to these examples, but is shown by the claims, and is intended to include all modifications within the meaning equivalent to the claims and within the scope.

[0019] [Structure of Connector 11] As Figure 1 and Figure 4 shown, the connector 11 is fixed to the ends of a plurality of electric wires 12, is fitted with the mating connector 13 on the opposite side, and is fixed to the metal housing 14 which is an external grounding member. In addition, the connector 11 of the present embodiment is fixed to the ends of two electric wires 12.

[0020] In addition, the first axis X, the second axis Y orthogonal to the first axis X, and the third axis Z orthogonal to the first axis X and the second axis Y are shown in the figure. In the present embodiment, the direction along the first axis X is defined as the width direction, the direction along the second axis Y is defined as the front-back direction, and the direction along the third axis Z is defined as the axial direction for explanation.

[0021] As Figure 2 and Figure 3 shown, the connector 11 includes terminals 21, a resin housing 22, a metal shell 23, rubber plugs 24, a stopper 25, a metal bracket 26, and a tightening ring 27. Two terminals 21, resin housings 22, and rubber plugs 24 are provided according to the number of electric wires 12.

[0022] [Structure of Terminals 21] As Figure 5 shown, the electric wire 12 has a core wire 12a and an insulating covering portion 12b. The terminal 21 is connected to the end of the core wire 12a exposed from the insulating covering portion 12b.

[0023] Specifically, the core wire 12a has a flat connection portion 12c that protrudes from the insulating coating portion 12b and has a shape that is flatter than the inside of the insulating coating portion 12b. That is, the flat connection portion 12c is smaller in diameter than the core wire 12a inside the insulating coating portion 12b in the thin-wall direction, which is the flat direction. A plurality of wires 12 are arranged such that the thin-wall direction of the flat connection portion 12c is along the width direction of the direction in which the plurality of wires 12 are arranged side by side. The terminal 21 has a terminal fitting portion 21a and a plate-shaped terminal connection portion 21b that connects to the flat connection portion 12c, and the mating terminal 13a of the mating connector 13 (see Figure 1 ) can be fitted into the terminal fitting portion 21a. In addition, the terminal 21 is formed by bending a metal plate, but in the drawings, the details thereof are not shown and are schematically illustrated. The terminal connection portion 21b of the terminal 21 overlaps the flat connection portion 12c in the plate thickness direction and is fixed by welding. In addition, in the present embodiment, the flat connection portion 12c is formed into a flat shape by being flattened while in contact with the terminal connection portion 21b, and resistance welding is performed with the terminal connection portion 21b in this state.

[0024] (Structure of the resin housing 22) As Figure 2 , Figure 3 and Figure 5 shown, the resin housing 22 is formed in a cylindrical shape so as to cover the exposed core wire 12a, that is, the flat connection portion 12c and the terminal 21. As Figure 3 shown, the resin housing 22 has a terminal opening 22a at a position corresponding to the terminal fitting portion 21a. The terminal opening 22a opens forward, and the mating terminal 13a (see Figure 1 ) can be inserted through the terminal opening 22a.

[0025] In addition, as Figure 5 shown, the resin housing 22 has a pair of narrowing wall portions 22b at positions that sandwich the flat connection portion 12c in the width direction. The widthwise interval of the pair of narrowing wall portions 22b gradually decreases as it approaches the tip direction along the axial direction and the tip direction of the core wire 12a.

[0026] In addition, the resin housing 22 has a pair of terminal covering wall portions 22c at positions that sandwich the terminal 21 in the width direction, and the interval between the inner surfaces of the pair of terminal covering wall portions 22c is set smaller than the diameter of the insulating coating portion 12b. That is, the resin housing 22 has a pair of narrowing wall portions 22b and a pair of terminal covering wall portions 22c so as to reduce the useless space inside according to the diameter of the insulating coating portion 12b, the width of the flat connection portion 12c, and the width of the terminal 21.

[0027] (Structure of the metal case 23) As shown Figure 5 As shown, the metal shell 23 is formed to cover the resin shell 22. The metal shell 23 has an opening 23a at the base end portion in the axial direction, and has a housing portion 23b extending in the tip direction in the axial direction. The housing portion 23b is formed into a shape that can house the resin shell 22 with substantially no gap according to the shape of the resin shell 22. Two housing portions 23b are arranged side by side in the width direction according to the number of resin shells 22. In addition, as shown Figure 6 As shown, the metal shell 23 has a communication hole 23c, and the communication hole 23c opens forward in a manner that communicates with the tip side of the housing portion 23b.

[0028] In addition, as shown Figure 5 As shown, the metal shell 23 has a partition wall 23d between the two housing portions 23b. The partition wall 23d is formed in the entire axial direction of the metal shell 23. And, as shown Figure 5 and Figure 6 As shown, a fixing hole 23e penetrating in the front-rear direction is provided in the partition wall 23d of the metal shell 23. That is, the fixing hole 23e is provided between the plurality of electric wires 12 in the width direction in which the plurality of electric wires 12 are arranged side by side. In other words, the fixing hole 23e is provided at a width direction position between the width direction position where one electric wire 12 is arranged and the width direction position where the other electric wire 12 is arranged. As shown Figure 5 As shown, the fixing hole 23e is provided between the flat connection portions 12c. In other words, the fixing hole 23e is provided at an axial position overlapping the axial position where the flat connection portion 12c is arranged. As shown Figure 1 and Figure 6 As shown, the metal shell 23 can be fixed to the metal outer shell 14 by a bolt 28 that penetrates the fixing hole 23e and engages with the female thread 14a of the metal outer shell 14.

[0029] (Structure of the rubber plug 24) As shown Figure 5 As shown, the rubber plug 24 is formed to prevent liquid from entering the connector 11 along the insulating coating portion 12b. Specifically, the rubber plug 24 is formed into a cylindrical shape interposed between the insulating coating portion 12b and the opening 23a of the metal shell 23. The rubber plug 24 prevents liquid from entering the connector 11 by being in close contact with the insulating coating portion 12b and the opening 23a of the metal shell 23.

[0030] (Structure of the stopper 25) As shown Figure 2 , Figure 3 and Figure 5As shown, the stopper body 25 is configured to be stuck to the metal case 23 to prevent the rubber plug 24 from falling off. Specifically, the stopper body 25 is made of resin. The stopper body 25 has two contact cylinder portions 25a that protrude outward from the metal case 23 and contact the outer periphery of the insulating coating portion 12b.

[0031] In addition, as Figure 2 and Figure 3 shown, the stopper body 25 has a flange portion 25b and locking pieces 25c. The flange portion 25b connects the axial ends of the two contact cylinder portions 25a to each other and extends outward. The locking pieces 25c are bent and extended from the flange portion 25b. Four locking pieces 25c are provided. The locking pieces 25c are respectively provided at positions in the front-rear direction of the contact cylinder portion 25a. The stopper body 25 is stuck to the metal case 23 by the locking pieces 25c engaging with the locking protrusions 23f provided on the outer surface of the metal case 23. And, the stopper body 25 prevents the rubber plug 24 from falling off from the opening 23a by the flange portion 25b being arranged to close the opening 23a. In addition, the stopper body 25 of the present embodiment is composed of two components assembled along the front-rear direction in such a manner as to sandwich the insulating coating portion 12b from the front and rear directions.

[0032] (Structure of the metal bracket 26) As Figure 6 shown, the metal bracket 26 is connected to the total shielding member 29 that is a shielding member covering the insulating coating portion 12b and is connected to the metal case 23. Specifically, the shielding member of the present embodiment is a cylindrical total shielding member 29 that collectively covers a plurality of insulating coating portions 12b. In addition, the total shielding member 29 of the present embodiment is a braided member formed by braiding conductive wires such as copper alloy and aluminum alloy into a cylindrical shape.

[0033] The metal bracket 26 has a cylinder portion 26a and a fastening portion 26b. The cylinder portion 26a is connected to the entire circumference of the total shielding member 29, and the fastening portion 26b extends from a part of the circumferential direction of the cylinder portion 26a. As Figure 2 shown, the cylinder portion 26a is formed in a shape that can cover the two contact cylinder portions 25a of the stopper body 25. Specifically, the cylinder portion 26a has a pair of parallel portions 26c and a pair of arc portions 26d that connect the pair of parallel portions 26c to each other in a semi-circular arc shape. And, in a state where the total shielding member 29 is arranged on the outer peripheral surface of the cylinder portion 26a, the total shielding member 29 is connected to the cylinder portion 26a by being tightened and fixed from the outside by a tightening ring 27.

[0034] The fastening portion 26b extends rearward from the end of one of the parallel portions 26c and is bent to extend in the axial direction. And, a fastening hole 26e is provided in the fastening portion 26b. In addition, the metal case 23 has an internal thread portion 23g. The internal thread portion 23g is provided on the outer surface at the rear of the metal case 23. And, as Figure 6As shown, the metal bracket 26 is fixed to the metal case 23 by a fastening screw 30 that passes through the fastening hole 26e and is screwed into the internal thread portion 23g.

[0035] In addition, as Figure 3 , Figure 7 and Figure 8 shown, the metal bracket 26 has a slit 26f on the side opposite to the fastening portion 26b in the circumferential direction of the cylindrical portion 26a, which serves as a circumferential engaging portion that can be engaged in the circumferential direction. The metal case 23 has a rib 23h that serves as a circumferentially engaged portion that engages with the slit 26f. Specifically, the metal bracket 26 has an extended portion 26g that extends along the axial direction from the cylindrical portion 26a. And the slit 26f extends along the axial direction of the cylindrical portion 26a from the center in the width direction at the tip of the extended portion 26g. In addition, the rib 23h is formed to protrude from the metal case 23 and extends along the axial direction of the cylindrical portion 26a and is inserted into the slit 26f.

[0036] In addition, as Figure 7 and Figure 8 shown, the metal case 23 has a positioning wall 23j that abuts against the tip of the extended portion 26g of the metal bracket 26. The positioning wall 23j is provided to be connected to the rib 23h and extends in both width directions from the rib 23h. The positioning wall 23j is set to abut against the axial tip of the extended portion 26g in a state where the rib 23h is inserted into the slit 26f.

[0037] Next, the operation of the connector 11 configured as described above will be described. The total shielding member 29 is electrically connected to the metal housing 14 via the metal bracket 26, the metal case 23, and the bolt 28 and is grounded. Therefore, electromagnetic noise radiated from the electric wire 12 and the terminal 21 covered by the total shielding member 29, the metal bracket 26, and the metal case 23 can be suppressed well. In addition, the opening 23a of the metal case 23 is filled with a rubber plug 24. Therefore, liquid is prevented from entering the connector 11 along the insulating coating portion 12b.

[0038] Next, the effects of the above-described embodiment will be described below. (1) The rubber plug 24 is interposed between the insulating coating portion 12b and the metal shell 23. Therefore, for example, compared with the rubber plug interposed between the insulating coating portion and the resin housing, miniaturization in the width direction of the connector 11 can be achieved. That is, in a structure where the rubber plug is interposed between the insulating coating portion and the resin housing, the rubber plug, the resin housing, and the metal shell are arranged in the width direction, resulting in enlargement of the connector 11 in the width direction, but this situation can be avoided. In addition, the fixing holes 23e are provided between the plurality of electric wires 12 in the width direction, so miniaturization in the width direction of the connector 11 can be achieved. That is, in a structure where the fixing holes are provided, for example, in a fixing portion protruding outward in the width direction of the metal shell 23, enlargement in the width direction of the connector 11 would occur, but this situation can be avoided. Thus, miniaturization in the width direction of the connector 11 can be achieved.

[0039] (2) The core wire 12a has a flat connection portion 12c, which is arranged such that the thin wall direction of the flat connection portion 12c is along the width direction. The fixing holes 23e are provided between the flat connection portions 12c, so miniaturization in the width direction of the connector 11 can be achieved. That is, by arranging the flat connection portions 12c such that the thin wall direction thereof is along the width direction, a relatively large space can be ensured between the flat connection portions 12c. Therefore, for example, the fixing holes 23e can be provided between the plurality of electric wires 12 without increasing the interval between the plurality of electric wires 12. Thus, miniaturization in the width direction of the connector 11 can be achieved.

[0040] (3) The terminal 21 has a plate-like terminal connection portion 21b, which is fixed to the flat connection portion 12c by welding. Therefore, for example, compared with a case where there is no plate-like terminal connection portion 21b and fixation is performed by crimping or the like, miniaturization in the width direction of the connector 11 can be achieved.

[0041] (4) The resin housing 22 has a pair of narrowing wall portions 22b at positions where the flat connection portions 12c are clamped. The interval in the width direction of the pair of narrowing wall portions 22b gradually decreases as it approaches the tip direction of the core wire 12a. Therefore, miniaturization in the width direction of the resin housing 22 can be achieved. That is, the size in the width direction of the flat connection portion 12c is smaller than that of the portion of the insulating coating portion 12b. Therefore, miniaturization in the width direction of the resin housing 22 can be achieved according to their sizes. Thus, miniaturization in the width direction of the connector 11 can be achieved.

[0042] (5) The resin housing 22 has a pair of terminal covering wall portions 22c at positions that sandwich the terminal 21 in the width direction, and the distance between the inner surfaces of the pair of terminal covering wall portions 22c is smaller than the diameter of the insulating covering portion 12b. Therefore, miniaturization in the width direction of the resin housing 22 at the position corresponding to the terminal 21 can be achieved. Accordingly, miniaturization in the width direction of the connector 11 can be achieved. That is, in a structure where the insulating covering portion 12b can also be accommodated at the portion where the distance between the inner surfaces of the pair of terminal covering wall portions 22c is located, the useless space between the pair of terminal covering wall portions 22c becomes larger, but this situation can be avoided.

[0043] This embodiment can be implemented with the following modifications. This embodiment and the following modification examples can be implemented in combination with each other within a range where there is no technical contradiction. ■ In the above embodiment, the core wire 12a has a flat connection portion 12c and is arranged such that the thin wall direction of the flat connection portion 12c is along the width direction of the connector 11, but this is not limited thereto, and it can also be changed to other structures. For example, the core wire 12a may not have a flat connection portion 12c.

[0044] ■ In the above embodiment, the fixing holes 23e are provided between the flat connection portions 12c, but this is not limited thereto, and they can also be provided at positions axially offset from between the flat connection portions 12c. For example, the fixing holes 23e can also be provided at positions axially offset from between the flat connection portions 12c and between the terminals 21. Additionally, for example, multiple fixing holes 23e can also be provided at the same position in the width direction of the connector 11 and at axially offset positions.

[0045] ■ In the above embodiment, the terminal 21 has a plate-like terminal connection portion 21b and is fixed to the flat connection portion 12c by welding, but this is not limited thereto, and it can also be changed to other structures. For example, the terminal 21 may not have a plate-like terminal connection portion 21b, but instead be fixed to the core wire 12a by crimping or the like.

[0046] ■ In the above embodiment, the resin housing 22 has a pair of narrowing wall portions 22b with a gradually decreasing distance in the width direction at the position where the flat connection portion 12c is sandwiched, but this is not limited thereto, and it can also be configured to not have a pair of narrowing wall portions 22b. For example, the resin housing 22 can also be configured to have a pair of wall portions with a constant distance in the width direction at the position where the flat connection portion 12c is sandwiched.

[0047] ■In the above-described embodiment, the distance between the inner surfaces of the pair of terminal covering wall portions 22c provided at positions that sandwich the terminal 21 in the width direction is smaller than the diameter of the insulating covering portion 12b. However, this is not limiting. For example, it may also be larger than the diameter of the insulating covering portion 12b. That is, the distance between the inner surfaces of the pair of terminal covering wall portions 22c may be such that it can also accommodate the insulating covering portion 12b.

[0048] ■In the above-described embodiment, the connector 11 is fixed to the ends of the two electric wires 12. However, this is not limiting. For example, it may also be fixed to the ends of three or more electric wires. In addition, in this case, it is necessary to change the number of terminals 21, resin housings 22, and rubber plugs 24 according to the number of electric wires 12. Further, in this case, the fixing holes 23e may be provided between all adjacent electric wires 12 in the width direction in which the multiple electric wires 12 are arranged side by side, or may be provided at only one location.

[0049] ■In the above-described embodiment, the external grounding member is the metal case 14. However, this is not limiting, and it may be changed to other external grounding members. For example, the metal case 14 may also be the vehicle body.

[0050] ■The structure of the metal bracket 26, the fixing structure of the metal bracket 26 to the metal case 23, etc. in the above-described embodiment may also be changed. For example, in the above-described embodiment, the total shielding member 29 is employed as the shielding member that covers the insulating covering portion 12b. However, in the case of employing a shielding member that separately covers the insulating covering portion 12b, etc., the structure of the metal bracket 26 may also be changed.

[0051] ■In the above-described embodiment, as Figure 5 shown, each resin housing 22 may be an elongated tubular member, or may be configured to cover the end of the insulating covering portion 12b of one electric wire 12, the core wire 12a exposed from the end of the insulating covering portion 12b, and the terminal 21 connected to the core wire 12a.

[0052] ■In the above-described embodiment, as Figure 5 shown, the metal case 23 may also be configured to accommodate the entire plurality of resin housings 22. The metal case 23 may have a plurality of opening portions 23a that are respectively connected to the plurality of housing accommodating portions 23b in the axial direction, and each opening portion 23a may also be configured to accommodate the rubber plug 24.

[0053] ■As Figure 6 shown, the internal threaded portion 23g of the metal case 23 may be located on the side opposite to the communication hole 23c of the metal case 23 in the circumferential direction, or may be provided between the plurality of electric wires 12 in such a manner that it is arranged axially along the fixing holes 23e of the metal case 23.

[0054] ■As in the illustrated embodiment, the terminal 21 may also be an elongated member extending along the third axis Z, i.e., the axial direction, inside the connector 11. As in the illustrated embodiment, the terminal 21 may be coaxially connected to the electric wire 12 at the tip of the electric wire 12.

[0055] ■In the illustrated embodiment, since the electric wire 12 is led out from the connector 11 in the third axis Z, i.e., the axial direction, the third axis Z, i.e., the axial direction, may sometimes be referred to as the lead-out direction of the electric wire from the connector. In the illustrated embodiment, the second axis Y, i.e., the front-rear direction, may sometimes be referred to as the mounting direction of the connector 11 relative to the mating connector 13 and / or the tightening direction of the bolt 28 relative to the mating connector 13.
