Description

[Technical Field]

[0001] The present invention relates to a connector shell that receives and holds a connector housing that holds one end of at least one electric wire. [Background technology]

[0002] In recent years, efforts to realize a low-carbon or carbon-free society have become more active, and research and development into the electrification of drive sources for automobiles and other vehicles has been conducted in order to reduce CO2 emissions and improve energy efficiency. As drive sources for automobiles and other vehicles become more electrified, the amount of power exchanged between batteries and drive sources has become larger. This has led to an increase in the importance of technologies related to waterproof structures that prevent electric wires carrying high power from becoming wet and short-circuiting, and shielding structures that shield against electromagnetic noise generated from electric wires carrying high power.

[0003] For example, Patent Document 1 describes a waterproof structure between a pin hole and a terminal pin, in which sufficient waterproof performance of the housing is obtained simply by press-fitting the terminal pin into a pin hole formed in the housing.

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2014-067560 Summary of the Invention [Problem to be solved by the invention]

[0005] However, the waterproof structure of Patent Document 1 has a problem in that stress concentrates near the pin holes of the housing, which can cause the housing to crack at the stress concentration point. Furthermore, the terminal pins must be press-fit into the pin holes with a large force, which makes assembly difficult. Furthermore, to ensure contact between the pin holes and the terminal pins to shield against electromagnetic noise, the housing and pins must be made of electrically conductive materials such as metal. However, if both the housing and the pins are made of metal, it becomes difficult to achieve sufficient waterproof performance for the housing.

DETAILED DESCRIPTION OF THE INVENTION

[0010] A connector including a connector shell according to an embodiment of the present invention will now be described with reference to the accompanying drawings. The drawings should be viewed in the direction indicated by the reference numerals.

[0011] (connector) 1 and 2, a connector 20 of this embodiment is provided at one end of a wire harness 10. Terminals (not shown) are provided at one end of each of the electric wires 11 and 12 that constitute the wire harness 10. The connector 20 includes a connector housing 30 that accommodates the terminals of the electric wires 11 and 12 and holds the one end of the electric wires 11 and 12, and a connector shell 40 that accommodates and holds the connector housing 30.

[0012] The connector housing 30 is made of an electrically insulating material, such as a synthetic resin material, and has a generally elongated cylindrical shape whose axis is along the direction in which the electric wires 11 and 12 extend within the connector housing 30, i.e., the direction in which the electric wires 11 and 12 protrude from the connector housing 30.

[0013] For simplicity and clarity of explanation, an XYZ Cartesian coordinate system is used in this specification. In the XYZ Cartesian coordinate system, the extension direction of the electric wires 11 and 12 within the connector housing 30, i.e., the direction in which the electric wires 11 and 12 protrude from the connector housing 30, is defined as the X-axis. Furthermore, a first direction perpendicular to the X-axis is defined as the Y-axis, and a second direction perpendicular to both the X-axis and the Y-axis is defined as the Z-axis. For convenience, the drawings show one side in the X-axis direction as X1, the other side in the X-axis direction as X2, one side in the Y-axis direction as Y1, the other side in the Y-axis direction as Y2, one side in the Z-axis direction as Z1, and the other side in the Z-axis direction as Z2. Furthermore, one end side of the electric wires 11 and 12 (the side where terminals, not shown, are provided) is defined as one side in the X-axis direction (X1 side), and the side opposite to the one end side of the electric wires 11 and 12 is defined as the other side in the X-axis direction (X2 side).

[0014] Therefore, the connector housing 30 has a generally elongated cylindrical shape with its axis aligned along the X-axis direction.

[0015] The connector shell 40 is made of an electrically conductive material, such as a metal material such as aluminum or an aluminum alloy. The connector shell 40 has a mating wall 41 that is a substantially elongated cylinder whose axis runs along the X-axis direction. Both the X1 side and the X2 side of the mating wall 41 are open. The mating wall 41 is formed to be able to accommodate the connector housing 30.

[0016] In the present embodiment, the connector housing 30 is accommodated in the fitting wall portion 41 from, for example, an opening on the X1 side of the fitting wall portion 41, and is fitted to the fitting wall portion 41. When the connector housing 30 is accommodated in the fitting wall portion 41 and fitted to the fitting wall portion 41, the X1 side end portion of the connector housing 30 protrudes from the X1 side opening end of the fitting wall portion 41 toward the X1 side.

[0017] (connector shell) As shown in Figures 1 to 4, the connector shell 40 has a flange portion 42 that extends in a flange-like shape in a direction approximately perpendicular to the X-axis direction from the X1-side end of the mating wall portion 41 toward the radially outer side of the mating wall portion 41 when viewed from the X-axis direction.

[0018] The flange portion 42 includes a fastening portion 42a that extends in the Y1 direction from the Y1-side end of the fitting wall portion 41 and has a bolt insertion hole 42b that penetrates in the X-axis direction. A fastening bolt 51, which is a fastening member, is inserted in the X-axis direction through the bolt insertion hole 42b of the fastening portion 42a. Therefore, the bolt insertion hole 42b and the fitting wall portion 41 are arranged side by side in the Y-axis direction so that the bolt insertion hole 42b is on the Y1 side and the fitting wall portion 41 is on the Y2 side when viewed from the X-axis direction.

[0019] The connector shell 40 is fixed to a fixing surface 91 of a fixing member 90 such as a case by fastening a fastening bolt 51 into a bolt fastening hole (not shown) provided in the fixing member 90 (see FIG. 5). The fixing surface 91 of the fixing member 90 is provided with an opening (not shown) through which the X1 side end of the connector housing 30 can be inserted. Then, by inserting the fastening bolt 51 into the bolt insertion hole 42b of the connector shell 40 and fastening it to the fixing member 90, the connector 20 is fixed to the fixing surface 91 of the fixing member 90 with the X1 side end of the connector housing 30 inserted through the opening in the fixing surface 91 of the fixing member 90. The fixing member 90 is preferably made of an electrically conductive material, and is preferably made of a metal material such as aluminum or an aluminum alloy.

[0020] The connector shell 40 has an abutment surface 43 that abuts against the fixed surface 91 of the fixed member 90 when the connector shell 40 is fixed to the fixed surface 91 of the fixed member 90. The abutment surface 43 is formed on the X1 side surface of the flange portion 42.

[0021] Fastening bolts 51 are fastened into bolt fastening holes (not shown) provided in a fixed member 90 such as a case, and the abutment surface 43 of the connector shell 40 is brought into close contact with the fixed surface 91 of the fixed member 90, thereby preventing water from entering the inside of the connector shell 40 from the outside. This prevents water from getting into the connector housing 30 and the one ends (including the terminals) of the electric wires 11 and 12 housed in the connector housing 30. In this case, in order to prevent water from entering the inside of the connector shell 40 from the outside, it is desirable to increase the area where the connector shell 40 and the fixed member 90 are in close contact with each other.

[0022] Furthermore, when fastening bolts 51 are fastened into bolt fastening holes (not shown) provided in a fixed member 90 such as a case, the abutting surface 43 of the connector shell 40 abuts against the fixed surface 91 of the fixed member 90, thereby electrically connecting the connector shell 40 and the fixed member 90. As a result, the connector shell 40 and the fixed member 90 are at ground potential, and electromagnetic noise generated when current flows through the electric wires 11 and 12 that constitute the wire harness 10 can be conducted to the fixed member 90. Therefore, the electromagnetic noise generated when current flows through the electric wires 11 and 12 that constitute the wire harness 10 is shielded by the connector shell 40, and leakage into the external space of the connector shell 40 is suppressed. In this case, in order for the connector shell 40 to effectively shield electromagnetic noise generated when current flows through the electric wires 11 and 12 that constitute the wire harness 10, it is desirable for the contact resistance between the abutting surface 43 of the connector shell 40 and the fixed surface 91 of the fixed member 90 to be small. In order to reduce the contact resistance between the abutment surface 43 of the connector shell 40 and the fixed surface 91 of the fixed member 90, it is desirable to increase the contact area between the abutment surface 43 of the connector shell 40 and the fixed surface 91 of the fixed member 90, and to increase the surface pressure between the abutment surface 43 of the connector shell 40 and the fixed surface 91 of the fixed member 90.

[0023] The abutment surface 43 has a tapered surface 431 that slopes toward the fixed surface 91 of the fixed member 90, and a fastening surface 432 that has a plane perpendicular to the axial direction (i.e., the X-axis direction) of the fastening bolt 51 that passes through the bolt insertion hole 42b, and in which the bolt insertion hole 42b is formed.

[0024] The tapered surface 431 has a tapered base end 431a and a tapered tip end 431b. The tapered surface 431 extends in the Y-axis direction from the tapered base end 431a to the tapered tip end 431b, and is inclined in a direction approaching the fixed surface 91 of the fixed member 90 from the tapered base end 431a toward the tapered tip end 431b.

[0025] In the Y-axis direction, the bolt insertion hole 42b is formed on the Y1 side of the fitting wall 41, the tapered tip portion 431b is formed on the Y2 side of the fitting wall 41, and the tapered base end portion 431a is formed between the bolt insertion hole 42b and the tapered tip portion 431b. Therefore, the tapered surface 431 extends in the Y-axis direction while inclining toward the fixed surface 91 of the fixed member 90 as it moves away from the bolt insertion hole 42b, and extends further toward the Y2 side than the fitting wall 41.

[0026] In addition, in the Y-axis direction, the tapered base end 431a of the tapered surface 431 is formed on the Y1 side of the mating wall portion 41, more specifically, on the Y1 side of the first end 41a, which is the Y1-side end of the mating wall portion 41, in other words, closer to the bolt insertion hole 42b than the first end 41a of the mating wall portion 41.

[0027] 5, when fastening bolt 51 starts to be threaded into a bolt fastening hole (not shown) provided in fixed member 90, first, tapered tip portion 431b of tapered surface 431 of abutment surface 43 comes into contact with fixed surface 91 of fixed member 90 (see FIG. 5(a)). As fastening bolt 51 continues to be threaded into the bolt fastening hole, tapered tip portion 431b of tapered surface 431 is pressed by fixed surface 91 of fixed member 90, and connector shell 40 elastically deforms, with tapered base end portion 431a of tapered surface 431 as a bending point, in a direction in which tapered surface 431 becomes a plane parallel to fixed surface 91 of fixed member 90. Then, when the fastening bolt 51 has been completely threaded into the bolt fastening hole and is fastened to the bolt fastening hole of the fastening bolt 51, the entire fastening surface 432 of the abutment surface 43 comes into close contact with the fixed surface 91 of the fixed member 90, and the entire tapered surface 431 of the abutment surface 43 comes into close contact with the fixed surface 91 of the fixed member 90 (see (b) of Figure 5).

[0028] This allows the area where the connector shell 40 and the fixed member 90 are in close contact to be wider, thereby effectively preventing water from entering the inside of the connector shell 40 and effectively preventing the connector housing 30 and the one ends (including each terminal) of the electric wires 11 and 12 housed in the connector housing 30 from becoming wet.

[0029] Furthermore, in addition to being able to increase the contact area between the abutment surface 43 of the connector shell 40 and the fixed surface 91 of the fixed member 90, the reaction force of the tapered surface 431 pressing against the fixed member 90 increases the surface pressure between the abutment surface 43 of the connector shell 40 and the fixed surface 91 of the fixed member 90, so that the contact resistance between the abutment surface 43 of the connector shell 40 and the fixed surface 91 of the fixed member 90 can be reduced, and the connector shell 40 can effectively shield electromagnetic noise generated when current is passed through the electric wires 11 and 12 that make up the wire harness 10.

[0030] When the connector shell 40 is fixed to the fixed surface 91 of the fixed member 90, the axial force of the fastening bolt 51 inserted through the bolt insertion hole 42b and fastened into the bolt fastening hole of the fixed member 90 causes the surface pressure of the fastening surface 432 near the bolt insertion hole 42b to be particularly high. Furthermore, the fastening surface 432 in which the bolt insertion hole 42b is formed has a plane perpendicular to the axial direction (i.e., the X-axis direction) of the fastening bolt 51 inserted through the bolt insertion hole 42b. Therefore, when the connector shell 40 is fixed to the fixed surface 91 of the fixed member 90, the surface pressure of the fastening surface 432 becomes even higher. As a result, when the connector shell 40 is fixed to the fixed surface 91 of the fixed member 90, the contact resistance between the fastening surface 432 and the fixed surface 91 of the fixed member 90 can be reduced, and the electromagnetic noise shielding performance of the connector shell 40 is further improved.

[0031] Furthermore, when connector shell 40 is fixed to fixed surface 91 of fixed member 90, the surface pressure at tapered tip 431b of tapered surface 431, which is pressed with the strongest force against fixed surface 91 of fixed member 90, becomes particularly high. This makes it possible to further reduce the contact resistance between tapered tip 431b of tapered surface 431 and fixed surface 91 of fixed member 90, and further improves the electromagnetic noise shielding performance of connector shell 40.

[0032] In this way, when the connector shell 40 is fixed to the fixed surface 91 of the fixed member 90, the surface pressure is particularly high near the bolt insertion hole 42b of the fastening surface 432 and near the tapered tip portion 431b of the tapered surface 431. As described above, in the Y-axis direction, the bolt insertion hole 42b is formed on the Y1 side of the fitting wall portion 41, the tapered tip portion 431b is formed on the Y2 side of the fitting wall portion 41, and the tapered base end portion 431a is formed between the bolt insertion hole 42b and the tapered tip portion 431b.

[0033] 5(c), even if the fastening bolt 51 fastened to the bolt fastening hole of the fixed member 90 loosens, the Y1-side end of the fastening surface 432 and the tapered tip portion 431b of the tapered surface 431 remain in contact with the fixed surface 91 of the fixed member 90, thereby suppressing a decrease in surface pressure on both the Y1 side and the Y2 side of the fitting wall portion 41. As a result, even if the fastening bolt 51 fastened to the bolt fastening hole of the fixed member 90 loosens, a reduction in the contact area between the abutment surface 43 of the connector shell 40 and the fixed surface 91 of the fixed member 90 and a decrease in surface pressure between the abutment surface 43 of the connector shell 40 and the fixed surface 91 of the fixed member 90 can be suppressed.

[0034] 1 to 4, in the flange portion 42, the connection portion 42c to which the fitting wall portion 41 is connected has high rigidity due to the substantially elongated cylindrical shape of the fitting wall portion 41. Therefore, in the flange portion 42, the connection portion 42c to which the fitting wall portion 41 is connected is not easily elastically deformed even when a load is input. Therefore, when the tapered base end 431a of the tapered surface 431 is formed in a position overlapping the area where the connection portion 42c is formed as viewed from the X-axis direction, even if the tapered tip end 431b of the tapered surface 431 is pressed against the fixed surface 91 of the fixed member 90 by threading the fastening bolt 51 into the bolt fastening hole, the tapered base end 431a of the tapered surface 431, which is the bending point, is not easily elastically deformed. Therefore, the connector shell 40 is not easily elastically deformed in a direction in which the tapered surface 431 becomes parallel to the fixed surface 91 of the fixed member 90.

[0035] In the present embodiment, the tapered base end 431a of the tapered surface 431 is formed on the Y1 side of the fitting wall portion 41 in the Y-axis direction. Therefore, the connector shell 40 can elastically deform, without being affected by the fitting wall portion 41, with the tapered base end 431a of the tapered surface 431 as a bending point, in a direction in which the tapered surface 431 becomes a plane parallel to the fixed surface 91 of the fixed member 90. Therefore, when the fastening bolt 51 is fastened to the bolt fastening hole of the fixed member 90, the connector shell 40 is likely to elastically deform, with the tapered base end 431a of the tapered surface 431 as a bending point, in a direction in which the tapered surface 431 becomes a plane parallel to the fixed surface 91 of the fixed member 90. This further improves the adhesion between the abutment surface 43 of the connector shell 40 and the fixed surface 91 of the fixed member 90, so that water can be more effectively prevented from entering the connector shell 40 and the electromagnetic noise shielding performance of the connector shell 40 is improved.

[0036] Although one embodiment of the present invention has been described above with reference to the accompanying drawings, it goes without saying that the present invention is not limited to such an embodiment. It is clear that a person skilled in the art can conceive of various modifications or alterations within the scope of the claims, and it is understood that these also naturally fall within the technical scope of the present invention. Furthermore, the components of the above embodiment may be combined in any manner without departing from the spirit of the invention.

[0037] For example, in this embodiment, the connector 20 having the connector shell 40 is provided at one end of the wire harness 10 consisting of two electric wires, the electric wire 11 and the electric wire 12, but the connector 20 having the connector shell 40 may be provided at one end of a wire harness consisting of one electric wire, or may be provided at one end of a wire harness consisting of three or more electric wires.

[0038] Also, for example, in this embodiment, the connector shell 40 is fixed to a fixed member 90 such as a case, but the case is one example of the fixed member 90, and the fixed member 90 may be a member other than a case, such as a panel member or a frame member.

[0039] Furthermore, for example, in this embodiment, the connector shell 40 is fixed to the fixed surface 91 of the fixed member 90 such as a case by fastening a fastening bolt 51 into a bolt fastening hole (not shown) provided in the fixed member 90, but the fastening member that fixes the connector shell 40 to the fixed surface 91 of the fixed member 90 may be any fastening member other than a fastening bolt, and may be, for example, a pin or a rivet.

[0040] This specification describes at least the following: In parentheses, components corresponding to those in the above-described embodiments are shown as examples, but the present invention is not limited to these.

[0041] (1) A connector shell (connector shell 40) that accommodates and holds a connector housing (connector housing 30) that holds one end of at least one electric wire (electric wires 11, 12) and is fixed to a fixing surface (fixing surface 91) of a fixing member (fixing member 90), the connector shell has an abutment surface (abutment surface 43) that faces the fixed surface of the fixed member and abuts against the fixed surface when the connector shell is fixed to the fixed surface of the fixed member, The connector shell, wherein the contact surface has a tapered surface (tapered surface 431) that is inclined toward the fixed surface of the fixed member.

[0042] According to (1), the area of ​​close contact between the connector shell and the fixed member can be increased, thereby effectively preventing water from entering the connector shell. Furthermore, in addition to increasing the contact area between the abutment surface of the connector shell and the fixed surface of the fixed member, the reaction force generated when the tapered surface is pressed against the fixed member increases the surface pressure between the abutment surface of the connector shell and the fixed surface of the fixed member, thereby reducing the contact resistance between the abutment surface of the connector shell and the fixed surface of the fixed member, thereby effectively shielding the connector shell from electromagnetic noise generated when electricity is passed through the electric wire. In this way, water can be effectively prevented from entering the connector shell, and electromagnetic noise generated when electricity is passed through the electric wire can be effectively shielded.

[0043] (2) The connector shell according to (1), The connector shell comprises: a fitting wall portion (fitting wall portion 41) extending in a cylindrical shape and into which the connector housing is fitted; a flange portion (flange portion 42) extending in a flange shape from an end portion of the fitting wall portion on the fixed member side, and forming the abutment surface; The flange portion has a fastening portion (fastening portion 42a) formed with an insertion hole (bolt insertion hole 42b) through which a fastening member (fastening bolt 51) to be fastened to the fixed member is inserted, the abutment surface includes the tapered surface and a fastening surface (fastening surface 432) having a flat surface perpendicular to the axial direction of the fastening member inserted through the insertion hole, The insertion hole is formed in the fastening surface of the connector shell.

[0044] According to (2), the fastening surface on which the insertion hole is formed has a plane perpendicular to the axial direction of the fastening member passing through the insertion hole, so that when the connector shell is fixed to the fixed surface of the fixed member, the surface pressure of the fastening surface is higher, which makes it possible to reduce the contact resistance between the fastening surface and the fixed surface of the fixed member when the connector shell is fixed to the fixed surface of the fixed member, and further improves the electromagnetic noise shielding performance of the connector shell.

[0045] (3) The connector shell according to (2), the insertion hole and the fitting wall portion are arranged side by side in a first direction when viewed from the axial direction of the fastening member, the tapered surface extends in the first direction from a tapered base end (tapered base end 431a) to a tapered tip end (tapered tip end 431b), and is inclined in a direction approaching the fixed surface of the fixed member as it extends from the tapered base end to the tapered tip end, A connector shell, wherein in the first direction, the insertion hole is formed on one side of the fitting wall portion in the first direction, the tapered tip portion is formed on the other side of the fitting wall portion in the first direction, and the tapered base end portion is formed between the insertion hole and the tapered tip portion.

[0046] According to (3), even if the fastening member fastened to the fixed member loosens, a decrease in surface pressure can be suppressed on both one side of the fitting wall in the first direction and the other side of the fitting wall in the first direction, near the insertion hole of the fastening surface and near the tapered tip of the tapered surface. As a result, even if the fastening member fastened to the fixed member loosens, a decrease in the contact area between the abutting surface of the connector shell and the fixed surface of the fixed member and a decrease in surface pressure between the abutting surface of the connector shell and the fixed surface of the fixed member can be suppressed. Therefore, an increase in contact resistance between the abutting surface of the connector shell and the fixed surface of the fixed member can be suppressed, and a decrease in the electromagnetic noise shielding performance of the connector shell can be suppressed.

[0047] (4) The connector shell according to (3), The connector shell, wherein the tapered base end portion is formed on the one side in the first direction relative to the fitting wall portion.

[0048] According to (4), since the tapered base end is formed on one side of the fitting wall in the first direction, when the fastening member is fastened to the fixed member, the connector shell is likely to elastically deform, with the tapered base end of the tapered surface as a bending point, in a direction in which the tapered surface becomes parallel to the fixed surface of the fixed member. This further improves the adhesion between the abutment surface of the connector shell and the fixed surface of the fixed member, making it possible to more effectively prevent water from entering the connector shell and improve the electromagnetic noise shielding performance of the connector shell.
