[Figure 2] FIG. 2 is a perspective view of the wire harness shown in FIG. [Figure 3] 3 is a partial top view of the connector housing shown in FIG. 1. FIG. [Figure 4] 4 is a front view of the connector housing shown in FIG. 1. FIG. [Figure 5] FIG. 5 is a partially enlarged perspective view of the wire harness shown in FIG. 1 when the cover member is in the open position. DETAILED DESCRIPTION OF THE INVENTION

[0011] Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0012] A wire harness 1 shown in FIG. 1 is installed in, for example, an automobile. The wire harness 1 includes a connector 2 (a resin exterior member) and electric wires 3 to which the connector 2 is attached at the terminal. The wire harness 1 is used, for example, to electrically connect devices (not shown). The connector 2 has a structure that makes an electrical connection by fastening a bolt (not shown). The connector 2 also has a structure that covers the electrical connection portion after the bolt is fastened, preventing the intrusion of moisture from the outside and the formation of rust.

[0013] For ease of explanation, the following definitions are used for the "front-rear direction," "left-right direction," "up-down direction," "front," "rear," "up," "down," "right," and "left" as shown in Figure 1 etc. The "front-rear direction," "left-right direction," and "up-down direction" are perpendicular to each other. The front-rear direction coincides with the longitudinal direction of the electric wire 3, with the connector 2 located on the front side and the electric wire 3 located on the rear side. The up-down direction also coincides with the bolt fastening direction between the connector and the mating connector.

[0014] The electric wire 3 is composed of a conductive conductor and an insulating insulator covering the outside of the conductor. The conductor is formed of copper, copper alloy, aluminum, or aluminum alloy and has a circular cross section. The insulator is extrusion-molded on the outer surface of the conductor using a thermoplastic resin material. The insulator is formed as a coating having a circular cross section. The insulator is formed to have a predetermined thickness. Note that various known types of thermoplastic resin can be used as the thermoplastic resin, and is appropriately selected from polymer materials such as polyvinyl chloride resin, polyethylene resin, and polypropylene resin. In the electric wire 3 described above, the insulation at the end is stripped to a predetermined length to form an exposed portion of the conductor (not shown).

[0015] As shown in FIG. 1, connector 2 includes terminal fitting 4 attached to the end of electric wire 3, connector housing 5 (housing) that accommodates terminal fitting 4, O-rings 6 and 7, cover member 8, first opening / closing mechanism 9 (FIG. 2), second opening / closing mechanism 10 (FIG. 2), back seal 11, and back retainer 12. Connector 2 is used as an electrical connection part with a mating device (not shown) mounted on an automobile. As can be seen from the above configuration and the diagram, connector 2 has a waterproof function. In addition, this waterproof function also provides an anti-corrosion function.

[0016] The terminal fitting 4 is formed by pressing a conductive metal plate. The terminal fitting 4 has an electric contact portion 41 and an electric wire connection portion 42. The electric contact portion 41 is fastened to a mating terminal of a mating device (not shown) with a bolt. The electric contact portion 41 is formed in a male shape (tab-shaped). A bolt insertion hole 411 that penetrates vertically is formed at the tip of the electric contact portion 41. In addition, three housing engagement portions 412 of different shapes are formed at the tip of the electric contact portion 41. The electric wire connection portion 42 is formed adjacent to the rear of such electric contact portion 41. The electric wire connection portion 42 is connected to the electric wire 3. Although not shown in detail in this embodiment, the electric wire connection portion 42 is formed in a known shape having a substrate, a pair of conductor crimping portions that crimp the conductor of the electric wire 3, and a pair of covering crimping portions that crimp the insulator of the electric wire 3.

[0017] 1, the connector housing 5 is an insulating resin molded product formed into the illustrated shape and having a housing main body 51 and a bolt fastening tubular portion 52. The connector housing 5 is formed into an integrated shape in which the housing main body 51 and the bolt fastening tubular portion 52 are continuous with each other using resin.

[0018] The housing body 51 is formed in a cylindrical shape with a central axis extending in the front-rear direction, and accommodates the wire connection portion 42 of the terminal fitting 4.

A retainer engagement portion 512 and a terminal insertion opening 513 are formed at the other end of the housing body 51. The middle of the housing body 51 (between the connecting portion 511 and the retainer engagement portion 512) is formed in a substantially cylindrical shape with flat surfaces on the top and bottom surfaces.

[0019] The connecting portion 511 is formed in a cylindrical portion with a rectangular cross section that is thinner in the vertical direction than the other end or the middle of the housing body 51. In this embodiment, the lower surface of the connecting portion 511 is formed to be flush with the flat lower surface provided in the middle of the housing body 51. The connecting portion 511 is connected to the side of the bolt fastening tubular portion 52 (described later), thereby connecting the housing body 51 and the bolt fastening tubular portion 52. The retainer engagement portion 512 is formed in a portion where the back retainer 12 engages. Such retainer engagement portion 512 is formed with a pair of engagement claws (not shown). The terminal insertion opening 513 is formed in a circular opening. The terminal insertion opening 513 is formed in a portion where the terminal fitting 4 is inserted from the side of the electrical contact portion 41. The terminal insertion opening 513 is also formed in a portion where the back seal 11 is inserted (press-fitted) and sealed watertightly by this back seal 11.

[0020] Keys 514 (protrusions) that protrude outward are provided on both left and right side surfaces of the connecting portion 511. As shown in FIG. 3, two keys 514 are provided side by side in the front-rear direction on the left side surface of the connecting portion 511, and two keys 514 are provided side by side in the front-rear direction on the right side surface of the connecting portion 511. The keys 514 provided on both side surfaces of the connecting portion 511 are positioned at different positions in the front-rear direction. In this embodiment, the key 514 provided on the right side surface of the connecting portion 511 is provided further forward than the key 514 provided on the left side surface of the connecting portion 511.

[0021] As shown in FIG. 1, the bolt fastening tubular portion 52 is formed in a tubular shape with its central axis extending in the vertical direction, and accommodates the electrical contact portion 41 of the terminal fitting 4. The bolt fastening tubular portion 52 is formed in a cylindrical shape. The bolt fastening tubular portion 52 has a first opening 521 and a second opening 522 (FIG. 4) at both ends. As shown in FIG. 4, two ring mounting portions 523, 524 are formed on the outer surface of the bolt fastening tubular portion 52. As shown in FIG. 1, the ring mounting portion 523 is provided on the first opening 521 side (upper side) of the connecting portion 511 of the housing main body 51, and an O-ring 6 is mounted therein. The ring mounting portion 524 is provided on the second opening 522 side (lower side) of the connecting portion 511 of the housing main body 51, and an O-ring 7 is mounted therein.

[0022] 4, in this embodiment, the ring attachment portion 523 is formed by a groove provided between a pair of annular flanges 525 that protrude from the outer surface of the bolt fastening cylindrical portion 52 and are spaced apart in the vertical direction. The ring attachment portion 524 is formed by a groove provided between a pair of annular flanges 526 that protrude from the outer surface of the bolt fastening cylindrical portion 52 and are spaced apart in the vertical direction. In addition, a waterproof flange 527 that protrudes outward from the upper sides of the pair of flanges 526 (edges of the ring attachment portion 524 (groove) on the first opening 521 side) is provided on the outer surface of the bolt fastening cylindrical portion 52.

[0023] Meanwhile, an intermediate opening (not shown) is formed in the middle of the side surface of the bolt fastening tubular portion 52. The above-mentioned connecting portion 511 is connected to the edge of this central opening. The intermediate opening is formed in a portion through which the electrical contact portion 41 of the terminal fitting 4 is inserted. The electrical contact portion 41 accommodated inside the bolt fastening tubular portion 52 through the intermediate opening is held by abutting against the middle of the inner surface of the bolt fastening tubular portion 52. Specifically, the housing engaging portion 412 of the electrical contact portion 41 is held by abutting against three terminal abutment portions 528 of different shapes formed in the middle of the inner surface of the bolt fastening tubular portion 52. The intermediate opening is located closer to the second opening 522 than the first opening 521.

[0024] 1, the cover member 8 is an insulating resin molded product similar to the connector housing 5. The cover member 8 is assembled to the connector housing 5 and is formed in a shape that allows it to open and close a first opening 521 that faces the electrical contact portion 41 of the terminal fitting 4. The cover member 8 has a top wall 81 that closes the first opening 521, and an annular side wall 82 that hangs down from the periphery of the top wall 81 when in the closed position (see FIG. 2).

[0025] 2, first opening / closing mechanism 9 is a mechanism that enables cover member 8 to be opened and closed relative to first opening 521. As shown in FIG. 1, first opening / closing mechanism 9 has a first rotating shaft 91 provided on cover member 8 and a first bearing portion 92 that is provided on housing main body 51 and rotatably holds first rotating shaft 91, and enables cover member 8 to be opened and closed by rotating cover member 8 around the axis of first rotating shaft 91.

[0026] As shown in Fig. 2, the cover member 8 is provided with a pair of first support portions 93 that protrude rearward from the side wall 82 in the closed state. The pair of first support portions 93 are provided spaced apart in the left-right direction. As shown in Fig. 1, a first rotating shaft 91 is supported between the tips of the pair of first support portions 93. The first rotating shaft 91 is provided in a cylindrical shape, and is supported by the first support portions 93 so that its central axis direction is along the left-right direction. The first rotating shaft 91 and the first support portions 93 are formed of resin into an integral shape that is continuous with the cover member 8.

[0027] The first bearing portion 92 is provided on the upper front side of the middle of the housing main body 51. The first bearing portion 92 is provided with a groove portion (not shown) that runs in the left-right direction, and an opening 94 of the groove is provided at the front. The width of the opening 94 is set to be shorter than the diameter of the first rotating shaft 91.

[0028] The first opening / closing mechanism 9 also has temporary locking portions 95, 96 that temporarily lock the cover member 8 in the open position. As shown in FIG. 5 , the temporary locking portion 95 protrudes from the side wall 82 of the cover member 8 and is provided so as to protrude rearward in the closed position from the left-right center of a connecting portion 97 that connects the bases of the pair of first support portions 93. The temporary locking portion 95 is formed in a substantially semicircular plate shape. The temporary locking portion 96 protrudes from the upper surface of the first bearing portion 92. The temporary locking portion 96 is provided on an inclined surface whose rear side surface protrudes toward the front.

[0029] The second opening / closing mechanism 10 is a mechanism that enables the cover member 8 to be opened and closed relative to the first opening 521. As shown in Fig. 1 , the second opening / closing mechanism 10 has a second rotating shaft 101 provided on the cover member 8 and a second bearing portion 102 that is provided on the bolt fastening cylindrical portion 52 and rotatably holds the second rotating shaft 101, and enables the cover member 8 to be opened and closed by rotating the cover member 8 around the axis of the second bearing portion 102.

[0030] As shown in FIG. 2 , the cover member 8 is provided with a pair of second support portions 103 that are generally L-shaped and protrude forward in the closed state and hang down from their tips. The pair of second support portions 103 are provided spaced apart in the left-right direction. A second rotating shaft 101 is supported between the tips of the pair of second support portions 103. The second rotating shaft 101 is provided in a cylindrical shape and is supported by the second support portions 103 so that its central axis extends along the left-right direction. In addition, the pair of second support portions 103 are provided with operating portions 105 that protrude outward in the left-right direction from corners of the L shape. The second rotating shaft 101, second support portions 103, and operating portion 105 are integrally molded with the cover member 8 using resin.

[0031] The second bearing portion 102 is provided in the bolt fastening cylindrical portion 52. The second bearing portion 102 is provided with a groove portion (not shown) along the left-right direction, and an opening 104 of the groove is provided on the side (upper side) of the cover member 8 on which the second rotating shaft 101 is provided. The width of the opening 104 is set shorter than the diameter of the second rotating shaft 101.

[0032] 1 and 2, the back seal 11 is a so-called rubber plug, and is formed into a shape that allows it to fit tightly against the outer surface of the insulator of the electric wire 3 and the terminal insertion opening 513 of the housing main body 51. The back seal 11 is prevented from falling off from the terminal insertion opening 513 by a back retainer 12. The back retainer 12 is assembled to the electric wire 3 together with the back seal 11 in advance, and is formed to engage with the retainer engagement portion 512 of the housing main body 51 after the terminal fitting 4 has been accommodated in the connector housing 5. The back retainer 12 is formed with portions (reference numerals omitted) that engage with the pair of engagement claws (not shown) of the retainer engagement portion 512.

[0033] Next, the assembly of the connector 2 having the above configuration and structure will be described below. The connector 2 is assembled by first assembling the back seal 11 and the back retainer 12 (see FIG. 1 ) to the electric wire 3 in advance, followed by a terminal processing process in which the terminal fitting 4 is connected to the end of the electric wire 3. Next, the cover member 8 is placed above the housing main body 51, and then a cover member assembling process is performed in which the first rotating shaft 91 provided on the cover member 8 is assembled to the first bearing portion 92 provided on the housing main body 51. In the cover member assembling process, the first rotating shaft 91 is inserted into the first bearing portion 92 through an opening 94 provided on the front side of the first bearing portion 92. As described above, the width of the opening 94 is smaller than the diameter of the first rotating shaft 91. Therefore, the first rotating shaft 91 is inserted into the first bearing portion 92 while pushing and widening the opening 94. When the first rotating shaft 91 is completely inserted into the first bearing portion 92, the width of the opening 94 is restored to its original width, so that the first rotating shaft 91 does not easily fall out of the opening 94.

[0034] Next, a terminal insertion and accommodation process is performed in which the terminal fitting 4, to which the electric wire 3 is connected in the above-mentioned terminal processing process, is inserted into the connector housing 5 from the side of the electrical contact portion 41. The terminal fitting 4 is inserted into the housing body 51 through a terminal insertion opening 513 provided at the other end of the housing body 51. The electrical contact portion 41 of the terminal fitting 4 passes through the middle of the housing body 51, the connecting portion 511, and is accommodated in the bolt fastening tubular portion 52. The electrical contact portion 41 accommodated in the bolt fastening tubular portion 52 is held in place by three housing engagement portions 412 formed at the tip of the electrical contact portion 41 abutting against three terminal abutment portions 528 formed on the inner surface of the bolt fastening tubular portion 52. Finally, a retainer assembling process is performed in which the back seal 11 and the back retainer 12 are slid to assemble the back seal 11 into the terminal insertion opening 513 and engage the back retainer 12 with the retainer engagement portion 512 of the housing body 51, thereby completing the assembly of the connector 2.

[0035] Next, the connection between the connector 2 and the mating device will be described. First, as shown in Fig. 5, the cover member 8 is rotated in the open direction around the first rotation shaft 91 to position the cover member 8 in the open position. At this time, the temporary locking portion 95 is located behind the temporary locking portion 96, so the cover member 8 is temporarily locked in the open position. In other words, even if a small force is applied to the cover member 8 in the closing direction, the temporary locking portion 95 cannot overcome the temporary locking portion 96, and the cover member 8 is maintained in the open position. Next, the second opening 522 is oriented toward the mating device, and the connector housing 5 below the coupling portion 511 is mated with the housing of the mating device.

[0036] The inner surface of the housing of the mating device is provided with a groove into which the key 514 can be slidably inserted. This prevents mating of different types of connector housings 5 ​​having different key 514 positions, thereby preventing incorrect assembly. For example, in this embodiment, as shown in FIG. 3, the connector housing 5 is of a type in which the key 514 on the right side is located forward of the key 514 on the left side. In contrast, a different type of connector housing 5 in which the key 514 on the right side is located rearward of the key 514 on the left side cannot be mated with the housing of the mating device.

[0037] At this time, a mating terminal is inserted through the second opening 522 and placed under the electrical contact portion 41. With the cover member 8 open, a bolt is inserted through the first opening 521 to fasten the electrical contact portion 41 and the mating terminal together. Then, the cover member 8 is rotated in the closing direction around the first rotating shaft 91. When a large force is applied to the cover member 8 in the closing direction, the temporary locking portion 95 overcomes the temporary locking portion 96 and is positioned forward of the temporary locking portion 96, allowing the cover member 8 to rotate in the closing direction. Then, the second rotating shaft 101 is inserted through the opening 104 facing upward in the second bearing portion 102. At this time, the second rotating shaft 101 is inserted into the second bearing portion 102 while pushing and widening the opening 104. When the second rotating shaft 101 is completely inserted into the second bearing portion 102, the width of the opening 104 returns to its original width. As a result, even if a small force is applied to the cover member 8 in the opening direction, there is no risk that the second rotation shaft 101 will come out of the opening 104 and the cover member 8 will open.

[0038] When maintenance is required on the connection between the electrical contact portion 41 and the mating terminal, the cover member 8 is rotated in the opening direction around the first rotating shaft 91 to expose the first opening 521. At this time, the worker holds the pair of operating parts 105 and lifts it upward, causing the second rotating shaft 101 to come out of the second bearing portion 102 through the opening 104, allowing the cover member 8 to rotate in the closing direction. Thereafter, the worker further rotates the cover member 8 in the opening direction to position the cover member 8 in the open direction as shown in FIG. 5.

[0039] This allows the electrical contact portion 41 to be viewed from the first opening 521, making it possible to perform maintenance work such as removing bolts. After the maintenance work is completed, the worker can position the cover member 8 in the closed position shown in Fig. 2 to close the first opening 521 and waterproof the terminal fitting 4.

[0040] According to the above-described embodiment, the connector 2 includes a first opening / closing mechanism 9 and a second opening / closing mechanism 10 that open and close the cover member 8. The second bearing portion 102 of the second opening / closing mechanism 10 has an opening 104 on the upper side for attaching and detaching the second rotating shaft 101 to and from the second bearing portion 102. As a result, when the front side of the cover member 8 is pushed upward, the second rotating shaft 101 moves out of the second bearing portion 102 through the opening 104, and the cover member 8 can rotate in the opening direction around the first rotating shaft 91 of the first opening / closing mechanism 9, thereby improving operability without the need for tools. Moreover, even if the first opening / closing mechanism 9 is damaged, the cover member 8 can be opened and closed by rotating it around the second rotating shaft 101 of the second opening / closing mechanism 10.

[0041] According to the above-described embodiment, the second opening / closing mechanism 10 has an operating part 105 that is provided on the cover member 8 and protrudes in the direction of the central axis (left-right direction) of the second rotating shaft 101. This makes it possible to easily push the operating part 105 upward to move the second rotating shaft 101 out of the second bearing part 102 through the opening 104, thereby improving workability.

[0042] According to the above-described embodiment, the connector housing 5 is provided with the keys 514 on both left and right sides of the connecting portion 511, and the keys 514 on both left and right sides are positioned at different positions in the front-rear direction. This makes it possible to prevent the connector housing 5 from being incorrectly assembled with the housing of the mating device.

[0043] According to the embodiment described above, bolt fastening tubular portion 52 has ring mounting portion 524 for accommodating O-ring 7, which is provided on the outer surface closer to second opening 522 than housing body 51, and flange portion 527 that protrudes outward from the edge (upper flange portion 526) of ring mounting portion 524 on the first opening 521 side. This prevents O-ring 7 from being exposed when viewed from above, thereby further improving waterproofing to the mating device.

[0044] According to the embodiment described above, the first opening and closing mechanism 9 has temporary locking portions 95, 96 that temporarily lock the cover member 8 in the open position. This allows the cover member 8 to be maintained in the open position, further improving operability.

[0045] The present invention is not limited to the above-described embodiments, and can be appropriately modified, improved, etc. Furthermore, the material, shape, size, number, location, etc. of each component in the above-described embodiments are arbitrary and not limited as long as they can achieve the present invention.

[0046] In the above-described embodiment, one second opening and closing mechanism 10 is provided, but this is not limited to this. A plurality of second opening and closing mechanisms 10 may be provided. For example, two second opening and closing mechanisms 10 may be provided on both the left and right sides of the cover member 8.
