Figure 2 From and Figure 1 A perspective view of connector 1 and mating connector of this embodiment, viewed from the opposite side. Figure 3 This is an exploded perspective view of connector 1 in this embodiment. Figure 4 This is a diagram of the connector 1 of this embodiment as viewed from the terminal housing 22 side. Figure 5 It is along Figure 4A magnified view of a portion of the line VV in the image. Figure 6 It shows along Figure 4 The cross-sectional view is a partially enlarged view of the cross section taken along with the mating housing 500a, using line VI-VI.

[0024] Common Reference Figures 1 to 6 Connector 1 is installed to the terminal of wire We. Connector 1 is electrically connected to a device (e.g., a vehicle inverter) in front of wire We. Connector 1 is electrically connected to the mating terminal connector 510 of mating device 500 (e.g., a vehicle rotary motor), thereby electrically connecting mating device 500 and the device in front of wire We to each other. The mating terminal connector 510 is disposed in the mating connector space 500b of mating housing 500a (the housing of mating device 500). The mating terminal connector 510 is electrically connected to connector 1 (terminal connector 10) embedded in the mating connector space 500b.

[0025] Connector 1 comprises three sets of paired terminal connectors 10 and wires We. Note that the number of paired terminal connectors 10 and wires We is not limited to the number mentioned above and can be adjusted according to design specifications.

[0026] The connector 1 includes: a terminal connector 10, which is mounted to the terminal of the wire We; a housing 20, which has a terminal receiving portion 22 that inwardly receives the terminal connector 10 and a wire receiving portion 24 that inwardly receives the wire We and leads the wire We outward; and a shielding shell 30, which has a cylindrical portion 31 that covers the wire receiving portion 24 from the outside and a fixing portion 33 that protrudes to one side from the cylindrical portion 31 and is cantilevered and fixed to the mating housing 500a.

[0027] In the following description, an orthogonal coordinate system of X, Y, and Z will be used as needed. In the X, Y, and Z directions, the side indicated by the arrow in the diagram will be referred to as the positive (+) side, and the side opposite to the arrow will be referred to as the negative (-) side. The Z direction corresponds to the mating direction of connector 1 and the mating connector. The +Z side corresponds to the front side (the side closer to the mating connector, the front side) in the mating direction when viewed from connector 1. The -Z side corresponds to the release side (the side farther from the mating connector, the rear side) in the mating direction when viewed from connector 1.

[0028] Terminal connectors

[0029] Terminal connector 10 is formed of a conductive material such as metal. For example, terminal connector 10 is formed by pressing a metal sheet as a base material, such as bending or cutting. Terminal connector 10 is electrically connected to wire We by being mounted to a terminal of wire We. Terminal connector 10 is physically and electrically connected to mating terminal connector 510 arranged in mating connector space 500b. Terminal connector 10 includes a terminal connection portion 11 physically and electrically connected to mating terminal connector 510, and a wire connection portion 12 physically and electrically connected to a terminal of wire We.

[0030] The terminal connection portion 11 is connected to the mating terminal connection portion 511 of the mating terminal connector 510 via a mating fit. The terminal connection portion 11 is formed in a cylindrical female terminal shape. The mating terminal connection portion 511 is inserted into the terminal connection portion 11. When the housing 20 of the connector 1 is inserted into the mating fit space 500b, the mating terminal connection portion 511 is inserted into the terminal connection portion 11 in a direction opposite to the insertion direction (+Z direction) of the housing 20 (-Z direction). The terminal connection portion 11 is formed in a corner cylindrical shape (female terminal shape) with four walls. The mating terminal connection portion 511 is formed in a flat shape (male terminal shape).

[0031] A contact member 13 having a resilient contact portion 13a is disposed inside the terminal connection portion 11. The resilient contact portion 13a is the portion that ensures the contact pressure between the contact and the mating terminal connection portion 511 through the elastic force generated by elastic deformation. The resilient contact portion 13a is disposed separately from the terminal connection portion 11 (terminal connector 10). Note that the resilient contact portion 13a may be disposed integrally with the terminal connection portion 11 (terminal connector 10).

[0032] By assembling the contact member 13 within the terminal connection portion 11, an elastic contact portion 13a is provided within the terminal connection portion 11. The elastic contact portion 13a contacts a plane of the flat mating terminal connection portion 511. The elastic contact portion 13a, for example, causes an orthogonal elastic force to act on a plane of the mating terminal connection portion 511.

[0033] The wire connection portion 12 is physically and electrically connected to the wire We, for example, by crimping or welding the core wire relative to the terminal of the wire We. The wire connection portion 12 is crimped to the core wire, for example, by forging two cylindrical pieces and connecting them to the exposed core wire.

[0034] The terminal connector 10 is formed in a straight line shape, wherein the terminal connection portion 11 and the wire connection portion 12 are arranged on the straight line. The wire We is led out from the wire connection portion 12 along the straight line in the extension direction (Z direction) of the terminal connector 10. Note that in the terminal connector 10, the terminal connection portion 11 and the wire connection portion 12 can be arranged orthogonally to each other or intersecting each other.

[0035] <Shell>

[0036] The housing 20 is formed of an insulating material such as synthetic resin. The housing 20 includes a terminal receiving portion 22 that inwardly houses the terminal connector 10 and a wire receiving portion 24 that inwardly houses the wire We and leads the wire We outward. The housing 20 houses the terminal connector 10 and the wire We in an internally completed position. In the housing 20, the terminal connector 10 is held in the completed position, and the wire We is led outward from the inside.

[0037] The housing 20 has a mating wall 21 that inserts into the mating space 500b from the insertion port 500c along the +Z direction. When viewed from the Z direction, the mating housing 500a has an elliptical insertion port 500c (the entrance to the mating space 500b). The mating wall 21 has an elliptical outer peripheral surface 21a with the same shape as the mating space 500b.

[0038] The housing 20 includes a terminal receiving portion 22 that inwardly accommodates a terminal connector 10. The terminal connector 10 is inserted into the terminal receiving chamber 20a from the wire outlet 24a of the wire receiving portion 24 along the +Z direction. The terminal receiving portion 22 protrudes toward the +Z side relative to the mating wall 21. The terminal receiving portion 22, together with the mating wall 21, is inserted into the mating space 500b from the insertion port 500c.

[0039] The connector 1 is configured to generate contact pressure between the contact and the mating terminal connection 511 without excess or insufficient due to the elastic deformation of the elastic contact portion 13a. The terminal connector 10 is housed in the terminal receiving chamber 20a by moving relative to the mating terminal connection 511 in the direction of the contact pressure. The connector 1 has the function of aligning the terminal connector 10 along the direction of the contact pressure. The terminal receiving chamber 20a is formed in an interior space in which the terminal connector 10 can move relative to each other in the alignment direction (Y direction). The terminal receiving chamber 20a is formed such that the terminal connector 10 can be disposed with a gap between it and the first wall 22a and the second wall 22b of the terminal receiving portion 22.

[0040] The first wall 22a and the second wall 22b are walls that form the terminal receiving chamber 20a in the terminal receiving portion 22. The first wall 22a and the second wall 22b are arranged opposite each other in the alignment direction (Y direction) with a space between them. The size of the gap between each of the first wall 22a and the second wall 22b and the terminal connector 10 is set such that the relative displacement of the terminal connector 10 relative to the mating terminal connection portion 511 can generate contact pressure between the contact of the elastic contact portion 13a and the mating terminal connection portion 511 without being excessive or insufficient.

[0041] The terminal receiving portion 22 is formed in the shape of a cylindrical angle. The cylindrical terminal connecting portion 11 is received in the terminal receiving chamber 20a within the terminal receiving portion 22. In the terminal receiving portion 22, the mating terminal connecting portion 511 is inserted into the terminal receiving chamber 20a through an opening on the cylindrical axial (Z direction) side. The mating terminal connecting portion 511 is inserted into the terminal connecting portion 11 in the terminal receiving chamber 20a.

[0042] The housing 20 has a terminal receiving portion 22 for each terminal connector 10. In the housing 20, three terminal receiving portions 22 are arranged at intervals in the X direction, and the number corresponds to the number of terminal connectors 10.

[0043] The housing 20 has a cover portion 23 disposed on the +Z side relative to the mating wall 21. The cover portion 23 is formed in a cylindrical shape, which covers the protrusion from the mating wall 21 in each terminal receiving portion 22 and leaves a gap with the outside. The cover portion 23 is formed in an elliptical cylindrical shape with an elliptical outer peripheral surface similar in shape to the mating mating space 500b.

[0044] The elliptical cylindrical mating terminal receiving portion 521 of the mating housing 520 is embedded in the elliptical annular gap between the cover portion 23 and each terminal receiving portion 22. The mating housing 520 is fixed to the mating housing 500a. The mating housing 520 is disposed in the mating fitting space 500b of the mating housing 500a. Each mating terminal connecting portion 511 within the mating terminal receiving portion 521 is inserted together with the mating terminal receiving portion 521 into each terminal receiving chamber 20a.

[0045] The cover 23 has an outer peripheral surface with a similar shape to the outer peripheral surface 21a of the mating wall 21. The connector 1 includes an annular or cylindrical sealing member 51 (hereinafter referred to as "first sealing member 51") that fills the annular or cylindrical gap between the outer peripheral surface 21a of the mating wall 21 and the inner peripheral surface of the mating space 500b circumferentially. The first sealing member 51 is formed in an elliptical shape, similar to the shape of the mating space 500b, resembling an elliptical annular or elliptical cylindrical shape. The first sealing member 51 is assembled to the outer peripheral surface 21a of the mating wall 21.

[0046] The housing 20 includes a wire receiving portion 24 that inwardly receives and outwardly leads a wire We. The wire receiving portion 24 is formed in a cylindrical shape. A wire receiving portion 24 is provided for each wire We in the housing 20. A cylindrical sealing member 52 (hereinafter referred to as "second sealing member 52") is assembled inside the wire receiving portion 24, which fills a portion of the cylindrical gap between the inner peripheral surface of the wire receiving portion 24 and the outer peripheral surface 21a of the wire We. A terminal connector 10, which is mounted to a terminal of the wire We, is inserted from the wire outlet 24a of the wire receiving portion 24 into the terminal receiving chamber 20a. The connector 1 includes a rear retainer 60 embedded in the gap between the wire outlet 24a of each wire receiving portion 24 and the wire We.

[0047] <Shielding Shell>

[0048] The shielding shell 30 is formed of a metallic material (e.g., aluminum or aluminum alloy). The shielding shell 30 has the function of suppressing noise from the outside intrusion into the internal wire We by covering the wire housing 24 from the outside.

[0049] The shielding shell 30 has a cylindrical portion 31 that covers the wire receiving portion 24 from the outside. The cylindrical portion 31 is formed into an elliptical cylindrical shape. In the shell 20, an elliptical annular sealing member 53 (hereinafter referred to as "third sealing member 53") is assembled to the elliptical outer peripheral surface of the wire receiving portion 24 relative to the fitting wall 21. The third sealing member 53 serves as a waterproof member, filling a portion of the elliptical cylindrical gap between the elliptical outer peripheral surface of the shell 20 and the inner peripheral surface of the cylindrical portion 31 of the shielding shell 30.

[0050] The shielding shell 30 has a fixing part 33 that protrudes to one side from the cylindrical part 31 and is cantilevered to the mating shell 500a. An elliptical annular flange part 32 is connected to the cylindrical part 31. In the shielding shell 30, the fixing part 33 protruding from the flange part 32 is tightened and fixed to the internal thread part N of the mating shell 500a by bolt B.

[0051] <Retaining Components>

[0052] Connector 1 includes a retaining member 40 that holds terminal connector 10 in a fully received position within terminal receiving chamber 20a. The retaining member 40 is formed of an insulating material such as synthetic resin. The retaining member 40 is assembled to terminal receiving portion 22. In the fully assembled position, the retaining member 40 prevents displacement of terminal connector 10 toward wire outlet 24a and prevents terminal connector 10 from falling off from wire outlet 24a. The retaining member 40 also stops movement of terminal connector 10 relative to terminal receiving portion 22 in a terminal removal direction (-Z direction) opposite to the terminal insertion direction (+Z direction) in the fully assembled position. The retaining member 40 holds terminal connector 10 in the fully received position within terminal receiving chamber 20a.

[0053] A retaining member 40 is provided for each terminal connector 10. The retaining member 40 can be provided for each terminal connector 10 or for each of a plurality of terminal connectors 10. The retaining member 40 can support (hold) all terminal connectors 10.

[0054] <Contact part>

[0055] The fixing portion 33 of the shielding shell 30 has a contact portion 34 that contacts the mating shell 500a in a cantilevered fixed state. The contact portion 34 includes a rib 35 provided at the protruding end of the fixing portion 33. The rib 35 protrudes from the surface (+Z side surface) of the fixing portion 33 opposite to the mating shell 500a toward the +Z side. The rib 35 and the fixing portion 33 are integrally formed as a single component. Note that the rib 35 may also be formed using a different component than that of the fixing portion 33.

[0056] Rib 35 has flexibility at least in the direction in which it contacts mating housing 500a. Rib 35 has flexibility in the Z direction and in directions intersecting the Z direction. Rib 35 is formed, for example, of a material softer than mating housing 500a (a part of mating housing 500b in contact with rib 35).

[0057] Rib 35 includes a first protrusion 35a disposed at the protruding end of fixing portion 33 and a second protrusion 35b extending from the first protrusion 35a along the outer edge of fixing portion 33. When viewed from the Z direction, the first protrusion 35a is rectangular in shape. When viewed from the Z direction, the second protrusion 35b extends from the +Y end of the first protrusion 35a to both sides in the X direction. In the Z direction, the protrusion height of the second protrusion 35b is lower than that of the first protrusion 35a. The protrusion height of the second protrusion 35b gradually decreases as it moves away from the first protrusion 35a.

[0058] The fixing part 33 has a bolt hole 33h, through which a bolt B for cantilever fixing to the mating housing 500a is inserted. A contact part 34 is provided near the bolt hole 33h in the fixing part 33. When viewed from the Z direction, the bolt hole 33h is circular.

[0059] When viewed from the Z direction, the contact portion 34 is located at a distance from the center of the bolt hole 33h that is equal to or less than a multiple of the diameter of the bolt hole 33h. For example, the contact portion 34 is preferably located at a distance from the center of the bolt hole 33h that is equal to or less than three times the diameter of the bolt hole 33h when viewed from the Z direction, and more preferably at a distance equal to or less than twice the diameter of the bolt hole 33h.

[0060] <Retaining Components>

[0061] Connector 1 also includes a retaining member 70, which holds bolt B in place by the retaining portion 33 when bolt B is removed from mating housing 500a. The retaining member 70 is formed in an annular or arcuate shape along the outer periphery of the shank of bolt B. The retaining member 70 is mounted to the shank of bolt B. Figure 6 In the example, the retaining member 70 is formed in an arc shape along the outer periphery of the shank of the bolt B and is embedded in a groove formed in the shank of the bolt B. A space 33a for accommodating the retaining member 70 is formed around the bolt hole 33h in the fixing portion 33 of the shielding shell 30.

[0062] <Instructions upon completion of connector fixing>

[0063] Figure 7 This is an explanatory diagram showing the completed installation of connector 1 in the comparative example. Figure 8 This is an explanatory diagram showing the connector 1 in this embodiment when it is fixed.

[0064] like Figure 7 As shown, the connector 1X in the comparative example does not include a rib (contact portion) that contacts the mating housing 500a when the shielding housing 30X is cantilevered. In the comparative example, the shielding housing 30X is cantilevered to the mating housing 500a, and when the fixing is complete, the shielding housing 30X is tilted. When the shielding housing 30X is tilted, a gap S is generated on the side opposite to the fixed side. In the comparative example, a gap S is generated between the connector 1X and the mating housing 500a.

[0065] like Figure 8 As shown, the connector 1 in this embodiment includes a rib 35, which contacts the mating housing 500a when the shielding shell 30 is fixed in a cantilevered manner. In this embodiment, the shielding shell 30 is fixed to the mating housing 500a in a cantilevered manner, and the shielding shell 30 does not tilt when the fixing is completed. In this embodiment, since the shielding shell 30 does not tilt, the generation of a gap between the connector 1 and the mating housing 500a can be suppressed.

[0066] <Operation and Effect>

[0067] As described above, the connector 1 of this embodiment includes: a terminal connector 10, which is installed to the terminal of the wire We; a housing 20, which has a terminal receiving portion 22 that inwardly accommodates the terminal connector 10, and a wire receiving portion 24 that inwardly accommodates the wire We and leads the wire We outward; and a shielding shell 30, which has a cylindrical portion 31 that covers the wire receiving portion 25 from the outside, and a fixing portion 33 that protrudes to one side from the cylindrical portion 31 and is cantilevered and fixed to the mating housing 500a. The fixing portion 33 includes a contact portion 34 that contacts the mating housing 500a in the cantilevered fixed state. According to this configuration, compared with the case where the fixing portion 33 does not contact the mating housing 500a in the cantilevered fixed state, the shielding shell 30 is less likely to tilt when fixed. Therefore, the generation of gaps due to the tilting of the shielding shell 30 can be suppressed. By suppressing the generation of gaps, the decrease in shielding performance of the shielding shell 30 and damage caused by external factors such as vibration can be avoided. In addition, the waterproof performance is improved. In addition, compared to adding bolt fasteners, it reduces tightening work and saves space.

[0068] In this embodiment, the contact portion 34 includes a rib 35 disposed at the protruding end of the fixing portion 33. According to this configuration, the contact between the rib 35 and the mating housing 500a can suppress the generation of gaps caused by the tilting of the shielding housing 30. Furthermore, compared to the case where the rib 35 is disposed inside the fixing portion 33 (near the cylindrical portion 31), the waterproof performance is improved.

[0069] In this embodiment, the rib 35 has flexibility, at least in the direction of contact with the mating housing 500a. According to this configuration, the generation of gaps due to the tilting of the shielding housing 30 can be suppressed by the bending of the rib 35. Furthermore, compared to the case where the rib 35 is formed of a rigid body, damage to the rib 35 due to external factors such as vibration can be suppressed.

[0070] In this embodiment, the rib 35 has a first protrusion 35a disposed at the protruding end of the fixing portion 33 and a second protrusion 35b extending from the first protrusion 35a along the outer edge of the fixing portion 33. According to this configuration, compared to the case where the rib 35 is only disposed at the protruding end of the fixing portion 33 (without the second protrusion 35b), the contact surface between the rib 35 and the mating housing 500a is increased, thereby more effectively suppressing the generation of gaps due to the tilting of the shielding shell 30. Furthermore, the waterproof performance is further improved.

[0071] In this embodiment, the fixing part 33 has a bolt hole 33h, through which a bolt B for cantilever fixing to the mating housing 500a is inserted. A contact part 34 is disposed near the bolt hole 33h in the fixing part 33. With this configuration, the generation of gaps due to the tilting of the shielding shell 30 can be suppressed by the contact part 34 near the bolt hole 33h. Furthermore, compared to the case where the contact part 34 is disposed at a predetermined distance or further from the bolt hole 33h in the fixing part 33, the generation of gaps can be suppressed and space can be saved.

[0072] In this embodiment, the connector 1 further includes a retaining member 70, which holds the bolt B in place by the fixing portion 33 when the bolt B is removed from the mating housing 500a. According to this configuration, the retaining member 70 prevents the bolt B from being removed from the fixing portion 33 when the bolt B is removed from the mating housing 500a.

[0073] <Second Embodiment>

[0074] The connector according to the second embodiment will be described below. In the following description, parts having the same functions as those described in the first embodiment are represented by the same names and designation numbers, and their specific descriptions will be omitted.

[0075] Figure 9 Is with Figure 6 Correspondingly shown is a cross-sectional view of the connector and mating housing 500a of the second embodiment.

[0076] like Figure 9 As shown, the contact portion 234 includes a surface 235 disposed around the bolt hole 233h in the fixing portion 233. The surface 235 disposed around the bolt hole 233h is formed into a planar shape parallel to the XY plane.

[0077] The fixing part 233 has an internal thread 233N, through which the bolt B is screwed into the inner circumference of the bolt hole 233h. The internal thread 233N is provided on the inner circumference of the bolt hole 233h in the opening direction (Z direction) of the bolt hole 233h. The bolt B has an external thread portion into which the internal thread 233N is screwed. The external thread portion of the bolt B is longer than the bolt hole 233h in the Z direction.

[0078] The internal thread 233N is provided in the opposite direction to the direction in which the bolt B is disassembled from the mating housing 500a. In other words, the internal thread 233N is provided in the same direction as the internal thread portion N provided in the mating housing 500a.

[0079] As described above, in this embodiment, the contact portion 234 includes a surface 235 disposed around the bolt hole 233h in the fixing portion 233. According to this configuration, the generation of gaps due to the tilting of the shielding shell can be suppressed by the contact between the surface 235 around the bolt hole 233h and the mating housing 500a. Furthermore, gaps generated due to the gap around the bolt hole 233h can be suppressed, and space can be saved.

[0080] In this embodiment, the fixing part 233 has an internal thread 233N, through which the bolt B is screwed onto the inner circumference of the bolt hole 233h. According to this configuration, the retaining member 70 that holds the bolt B in place by the fixing part 233 becomes unnecessary when the bolt B is removed from the mating housing 500a. By eliminating the retaining member 70, gaps caused by the clearance around the bolt hole 233h can be suppressed, and gaps caused by the tilting of the shielding housing can be suppressed more effectively. Furthermore, this helps reduce the number of components and the workflow.

[0081] In this embodiment, the internal thread 233N is threaded in a direction opposite to the direction in which the bolt B is removed from the mating housing 500a. According to this configuration, compared to the case where the internal thread 233N is threaded in the same direction as the bolt B is removed from the mating housing 500a, when the bolt B is removed from the mating housing 500a and the fixing of the shielding shell is released, the removal of only the bolt B can be suppressed. That is, the bolt B and the shielding shell can be easily removed together.

[0082] <Third Embodiment>

[0083] The connector according to the third embodiment will be described below. In the following description, parts having the same functions as those described in the first embodiment are represented by the same names and designation numbers, and their specific descriptions will be omitted.

[0084] Figure 10 Is with Figure 6 The corresponding cross-sectional view of the connector and mating housing 500a of the third embodiment is shown.

[0085] like Figure 10 As shown, a bolt hole 333h is formed in the fixing part 333, through which a bolt B for cantilever fixing to the mating housing 500a is inserted. The bolt hole 333h is formed to open at an axial inclination relative to the bolt B when the fixing part 333 is cantilevered. Figure 10 In the example, the bolt hole 333h is inclined relative to the axial direction of the bolt B, so that it is positioned on the -Y side as it moves in the +Z direction. A portion of the shank of the bolt B on both the -Y and -Z sides contacts a portion of the inner circumferential surface of the bolt hole 333h at the end on the -Y side toward the -Z side.

[0086] As described above, in this embodiment, the bolt hole 333h is formed to open obliquely relative to the axial direction of the bolt B when the fixing part 333 is fixed in a cantilever manner. According to this configuration, the generation of gaps caused by the inclination of the shielding shell can be suppressed by the contact between the inner peripheral surface of the obliquely opened bolt hole 333h and the shank of the bolt B.

[0087] <Variation Example>

[0088] In the above embodiments, an example has been described where the contact portion includes a rib disposed at the protruding end of the fixing portion, but the invention is not limited to this example. For example, the contact portion may include a rib disposed inside the fixing portion (near the cylindrical portion). For example, the contact portion may include a protrusion projecting from a portion of the fixing portion toward the mating housing. The construction aspects of the contact portion may be varied according to design specifications.

[0089] In the above embodiments, an example has been described where the rib includes a first protrusion disposed at the protruding end of the fixing portion and a second protrusion extending from the first protrusion along the outer edge of the fixing portion; however, the invention is not limited to this example. For example, the rib may only be disposed at the protruding end of the fixing portion. For example, the rib may not need to have a second protrusion. The construction aspects of the rib can be modified according to design specifications.

[0090] In the above embodiments, examples have been described of ribs having flexibility, at least in the direction of contact between the rib and the mating shell, but the invention is not limited to these examples. For example, the rib may be formed of a rigid body. For example, the rib may be made of a material (metal) with higher rigidity than the mating shell. Construction aspects of the rib can be modified according to design specifications.

[0091] In the above embodiments, an example has been described in which bolt holes are formed in the fixing portion, bolts for cantilever fixing to the mating housing are inserted through the bolt holes, and a contact portion is provided near the bolt holes in the fixing portion; however, the present invention is not limited to this example. For example, the contact portion may be provided at a predetermined distance from or further away from the bolt holes in the fixing portion. The installation aspects of the contact portion in the fixing portion can be modified according to design specifications.

[0092] In the above embodiments, an example has been described where the contact portion is a surface surrounding a bolt hole in the fixing portion; however, the invention is not limited to this example. For instance, the contact portion could be a protrusion surrounding a bolt hole in the fixing portion. Aspects of the contact portion can be modified according to design specifications.

[0093] In the above embodiments, an example has been described where the internal thread is threaded in the direction opposite to the direction in which the bolt is removed from the mating housing; however, the invention is not limited to this example. For example, the internal thread may be threaded in the same direction as the direction in which the bolt is removed from the mating housing. The thread direction of the internal thread may be changed according to design specifications.

[0094] In the above embodiments, an example has been described where the connector further includes a retaining member that holds the bolt in place when the bolt is removed from the mating housing; however, the invention is not limited to this example. For instance, the connector may not need to include a retaining member. The mounting aspects of the retaining member can be modified according to design specifications.

[0095] Although embodiments and modifications have been described above, they are not limited to these examples. Embodiments and modifications can be made by adding, omitting, substituting, or otherwise altering the construction, and can be combined with each other, without departing from the spirit of this disclosure. Therefore, the invention should not be considered as limited to the foregoing description, but only to the scope of the appended claims.
