Each male terminal 2 is electrically connected to a conductor of an unshown electric wire constituting a part of the wire harness WH 1.
The male connector 3 is a first connector, and as shown in fig. 1 to 4, houses the male terminal 2. The male connector 3 has an inner housing 31, an outer housing 32, and a second seal member 33.
As shown in fig. 2, 3 and 6, the inner housing 31 is formed with a male terminal receiving chamber 34 a. The inner housing 31 of the present embodiment includes an inner housing body portion 34 and a terminal cover portion 35.
The inner housing body portion 34 includes: the base portion 341, the flange portion 342, the first locking claw 343, and the second locking claw 344. The base portion 341 is formed in a rectangular shape when viewed from the front-rear direction, and a male terminal accommodating chamber 34a communicating with the outside in the front-rear direction is formed. The male terminal receiving chamber 34a is a first terminal receiving chamber and is formed in the male connector 3 corresponding to each male terminal 2. Here, in the state where each male terminal 2 is housed in each male terminal housing chamber 34a, the tip end portion, which is the end portion in the external direction, protrudes outward from each male terminal housing chamber 34 a. That is, in the housed state, the tip end portion of each male terminal 2 is exposed to the outside from the inner housing body portion 34. In the locked state in which the inner case 31 is locked to the outer case 32, the flange portion 342 is positioned in the through hole 100 a. The flange portion 342 is formed to protrude from the end portion of the base portion 341 in the inner direction. The first locking claw 343 is formed on the base 341 and locks the terminal cover portion 35 to the inner housing body portion 34. The first locking claw 343 of the present embodiment is formed to protrude downward from the outer peripheral surface of the base 341 located below. The first catching claw 343 is elastically deformable toward the inside of the base 341. The second locking claw 344 is formed on the base portion 341 and locks the inner case 31 to the outer case 32. The second locking claws 344 of the present embodiment are formed in a pair in the width direction with respect to the base portion 341. One of the pair of second locking claws is formed to protrude leftward from the outer peripheral side surface on the left side of the outer peripheral surface of the base portion 341, and the other is formed to protrude rightward from the outer peripheral side surface on the right side of the outer peripheral surface. The pair of second catching claws 344 is elastically deformable toward the inside of the base portion 341.
The terminal cover portion 35 protects the male terminal 2. The terminal cover portion 35 of the present embodiment is a member different from the inner housing body portion 34, and surrounds the tip end portions of the male terminals 2 exposed to the outside from the inner housing body portion 34 in the housed state. The terminal cover portion 35 has: base portion 351, first locked portion (japanese: first interference け)352, and convex portion 353. The base portion 351 is formed in a rectangular tubular shape when viewed from the front-rear direction, and a protective space portion 35a communicating with the outside in the front-rear direction is formed. The protective space portion 35a is a space portion in which the tip end portion of each male terminal 2 is located in the housed state. The first engaged portion 352 is formed in the base portion 351 and engages the terminal cover portion 35 with the inner housing body portion 34. The first locked portion 352 of the present embodiment is formed on the inner direction side of the locking opening 35b, and the locking opening 35b is formed on the lower outer circumferential side surface of the outer circumferential surface of the base 351. Here, the first locking claw 343 is locked by the first locked portion 352, so that the tip end portion of each male terminal 2 is positioned in the protection space portion 35a in the locked state where the terminal cover portion 35 is locked to the inner housing body portion 34, and is not exposed from the terminal cover portion 35 when viewed in the width direction. The base 351 is formed with an exposure opening 35 c. In the locked state, the exposure opening 35c exposes the second locking claw 344 to the outside of the terminal cover portion 35. The exposure opening 35c of the present embodiment is formed in the base portion 341 in a pair in the width direction so as to correspond to the second locking claws 344, respectively. The pair of exposure openings 35c are formed such that: one penetrates the left side surface of the outer peripheral surface of the base portion 341, and the other penetrates the right side surface of the outer peripheral surface of the base portion 341. The convex portions 353 are formed corresponding to the respective male terminal receiving chambers 34 a. The convex portion 353 of the present embodiment is formed to protrude rearward from the partition wall formed in the middle of the front-rear direction in the protective space portion 35 a. In the locked state in which the terminal cover portion 35 is locked to the inner housing body portion 34, the projection 353 vertically faces a Lance (Lance)345 correspondingly formed in each of the male terminal accommodating chambers 34 a. Here, when the male terminal 2 is inserted into the male terminal accommodating chamber 34a, the lock lever 345 is elastically deformed upward, and in a state where the male terminal 2 is inserted into the male terminal accommodating chamber 34a, the lock lever 345 faces the male terminal 2 in the front-rear direction, and restricts the movement of the male terminal 2 in the front-rear direction with respect to the inner housing body 343. In the locked state, the projection 353 and the hook 345 face each other in the vertical direction, and thereby the hook 345 can be restricted from being elastically deformed in a direction in which the facing of the hook 345 and the male terminal 2 is released.
As shown in fig. 2, 3, 5, and 6, the outer case 32 is fixed to the partition wall 100 on the outer side of the partition wall 100. In the accommodated state in which the inner housing 31 is accommodated inside, the outer housing 32 is engaged with the female connector 5. The outer case 32 includes a base 321, a flange 322, a second engaged portion 323, and a cam protrusion 324. The base portion 321 is formed in a rectangular shape when viewed from the front-rear direction, and a case housing space 32a communicating with the outside in the front-rear direction is formed. The housing accommodating space portion 32a accommodates the inner housing 31 in the outer housing 32. In the fixed state in which the outer case 32 is fixed to the partition wall 100, the flange portion 322 is located further to the outside than the outer surface 100c of the partition wall 100. The flange portion 322 is formed to protrude from the end portion of the base portion 321 in the inner direction, and has a sealing groove portion 32b and an insertion hole 32 c. The sealing groove portion 32b holds the second sealing member 33 with respect to the outer case 32 by inserting the second sealing member 33. The sealing groove portion 32b of the present embodiment is formed in an annular shape surrounding the case accommodating space portion 32a when viewed from the front-rear direction. The insertion holes 32c of the present embodiment correspond to the respective fixing holes 100b, and are formed in a pair in the width direction with respect to the flange portion 322. The pair of insertion holes 32c are formed to penetrate the flange portion 322 in the front-rear direction. Here, the fixing members inserted into the respective insertion holes 32c are fixed to the respective fixing holes 100b, and thereby the outer case 32 is fixed to the partition wall 100 on the outer side of the partition wall 100. In the fixed state in which the outer case 32 is fixed by the partition wall, the through hole 100a communicates with the case housing space portion 32a, and therefore, the inner case 31 can be housed inside the outer case 32 from the inside of the partition wall 100 via the through hole 100 a. The second engaged portion 323 is formed in the base portion 321, and engages the inner case 31 with the outer case 32. The second engaged portion 323 of the present embodiment is formed as a pair in the width direction with respect to the base portion 321. One of the pair of second engaged portions 323 is formed to protrude rightward from the inner wall surface located on the left side out of the inner wall surfaces constituting the housing accommodating space portion 32a, and the other is formed to protrude leftward from the inner wall surface located on the right side out of the inner wall surfaces. The cam protrusion 324 is inserted into a cam groove 52b described later, and engages the female connector 5 with the male connector 3 in accordance with the rotational operation of the lever member 52 described later, and the cam protrusion 324 formed on the base portion 321 in the present embodiment is formed in a pair in the vertical direction with respect to the base portion 321. One of the pair of cam protrusions 324 is formed to protrude upward from an outer peripheral side surface located above of the outer peripheral surface of the base 321, and the other is formed to protrude rightward from an outer peripheral side surface located below of the outer peripheral surface.
As shown in fig. 4, the second seal member 33 seals between the outer case 32 and the partition wall 100. The second seal member 33 of the present embodiment is, for example, a member having elasticity, and is formed in a ring shape having an opening 33a when viewed from the front-rear direction, and in an inserted state into the sealing groove portion 32b, the second seal member 33 is formed so as to protrude to the outside direction side with respect to the sealing groove portion 32 b. That is, in the inserted state, the second seal member 33 protrudes to the outside direction side than the surface on the outside direction side of the flange portion 322. Therefore, when the outer case 32 is fixed to the partition wall 100 on the outer surface side of the partition wall 100, the second seal member 33 seals between the outer case 32 and the partition wall 100, and thereby, the liquid can be restricted from entering between the through hole 100a and the case accommodating space portion 32 a.
The female terminal 4 is a second terminal, and is electrically connected to the mating-side electronic device 400 through the partition wall 100, as shown in fig. 1, 2, and 5. The plurality of female terminals 4 are received in the female connector 5. Each female terminal 4 is electrically connected to a conductor of an unshown electric wire constituting a part of the wire harness WH 2. In addition, a waterproof sleeve is attached to the electric wire electrically connected to the female terminal 4, and the female terminal accommodating chamber 51b is closed by the waterproof sleeve in an accommodated state after being accommodated in a female terminal accommodating chamber 51b described later.
The female connector 5 is a second connector, and as shown in fig. 1, 2, 5, and 8, houses the female terminal 4. The female connector 5 is fitted to the male connector 3, thereby electrically connecting the male terminal 2 and the female terminal 4 via a through hole formed in the partition wall 100. The female connector 5 has a base 51, a lever 52, and a rotary shaft 53.
When viewed from the front-rear direction, the base portion 51 is formed in a rectangular shape, and a connector housing space portion 51a communicating with the outside in the external direction is formed. The connector receiving space portion 51a receives the male connector 3 inside the female connector 5. The base portion 51 is formed with a female terminal accommodating chamber 51b communicating with the outside in the front-rear direction. The female terminal receiving chambers 51b are second terminal receiving chambers, and are formed in the female connector 5 corresponding to the female terminals 4. The female terminal receiving chamber 51b of the present embodiment is formed as a protruding portion protruding in the external direction in the connector receiving space portion 51 a. That is, when viewed from the front-rear direction, the connector housing space 51a is formed in an annular shape by the protruding portion. Here, in the accommodated state after the female terminals 4 are accommodated in the female terminal accommodating chambers 51b, the end portions of the female terminals 5 in the external direction, i.e., the tip end portions, are not exposed to the outside from the base portion 51.
The lever portion 52 engages the female connector 5 with the male connector 3. The lever portion 52 constitutes a cam mechanism together with the cam protrusion 324 of the male connector 3, and the relative distance between the female connector 5 and the male connector 3 in the front-rear direction is reduced by the rotational operation of the lever portion 52, thereby maintaining the connected state in which the male terminal 2 and the female terminal 4 are electrically connected. The lever portion 52 of the present embodiment is formed in a U shape, and rotation holes 52a are formed at both ends. The lever portion 52 has cam grooves 52b formed on the inner peripheral surfaces of both end portions, and the inserted cam protrusion 324 slides in the cam grooves 52b in accordance with the rotational movement of the lever portion 52, thereby engaging the female connector 5 with the male connector 3.
The rotation shaft 53 rotates the lever portion 52 about the vertical direction with respect to the base portion 51. The rotation shaft 53 is formed in a pair in the vertical direction with respect to the base portion 341 so as to correspond to each rotation hole 52 a. One of the pair of rotating shafts 53 is formed to protrude upward from an upper outer peripheral surface of the base 51, and the other is formed to protrude downward from a lower outer peripheral surface of the outer peripheral surface.
As shown in fig. 5, the first seal member 6 seals between the male connector 3 and the female connector 5. The first seal member 6 of the present embodiment is, for example, a member having elasticity, and is formed in a ring shape having an opening 6a when viewed from the front-rear direction, and the protruding portion of the base portion 51 is inserted into the opening 6a in an inserted state of being inserted into the connector housing space portion 51 a. Therefore, when the female connector 5 is engaged with the male connector 3, the first seal member 6 is disposed between the base portion 51 and the outer housing 32, and seals between the female connector 5 and the outer housing 32, whereby the liquid can be restricted from entering between the connector housing space portion 51a and the housing space portion 32 a.
Next, a fitting method of the waterproof connector structure 1 will be described. First, the operator inserts the second sealing member 33 into the sealing groove portion 32b of the outer housing 32 of the male connector 3 in advance. The terminal cover 35 is assembled to the inner housing body 34 by inserting the male terminals 2 constituting a part of the wire harness WH1 into the male terminal accommodating chambers 34a of the inner housing 31 and locking the first locking claw 343 to the first locked portion 352. That is, the male connector 3 is provided in advance in a state of constituting a part of the wire harness WH1 except the outer housing 32. On the other hand, the operator previously assembles the lever portion 52 to the base portion 51 of the female connector 5 and inserts the first seal member 6 into the connector housing space portion 51a of the base portion 51. In addition, the female terminals 4 constituting a part of the wire harness WH2 are inserted into the female terminal receiving chambers 51b of the base 51. That is, the female connector 5 is provided in advance in a state of constituting a part of the wire harness WH 2.
Next, as shown in fig. 6, the operator arranges the outer case 32 outside the partition wall 100 so that the through hole 100a faces the case housing space 32a in the front-rear direction. Next, the operator moves the outer case 32 in the inner direction (arrow a in the figure) with respect to the partition wall 100, brings the second seal member 33 into contact with the outer surface 100c of the partition wall 100 and the inner wall surface constituting the through hole 100a, and causes the insertion hole 32c and the fixed hole 100b to face each other in the front-rear direction. Next, the operator inserts the fixing member into the insertion hole 32c and screws the fixing member into the fixing hole 100b, thereby fixing the outer case 32 to the partition wall 100 as shown in fig. 7. Thereby, the outer case 32 is fixed to the partition wall 100 on the outer side of the partition wall 100 so as to sandwich the second seal member 33. Therefore, the housing accommodating space portion 32a communicates with the through hole 100a in a state of being sealed by the second sealing member 33.
Next, the operator arranges the inner case 31 inside the partition wall 100 so as to face the through hole 100a in the front-rear direction. Next, the operator moves the inner housing 31 in the inner direction (arrow B in the figure) with respect to the partition wall 100 and inserts the inner housing 31 into the housing accommodating space portion 32a through the through hole 100 a. At this time, the second locking claw 344 is locked to the second locked portion 323, and the inner case 31 is locked to the outer case 32. Thereby, the inner housing 31 is housed inside the outer housing 32 from the inside of the partition wall 100 in a state where the male terminal 2 is housed in the male terminal housing chamber 34 a.
Next, as shown in fig. 8, the operator arranges the female connector 5 on the outer side of the partition wall 100 so as to face the outer housing 32 in the front-rear direction. Next, the operator moves the female connector 5 in the inner direction (arrow C in the figure) with respect to the outer housing 32, and inserts the outer housing 32 into the connector housing space portion 51 a. Next, the operator rotates the lever portion 52 relative to the base portion 51 about the rotation shaft 53 in an engagement direction (arrow D in the figure) in which the female connector 5 is engaged with the outer housing 32. Thus, the first sealing member 6 is brought into contact with the base portion 51 and the outer housing 32 in the connector housing space portion 51a, and the male terminal 2 and the female terminal 4 are electrically connected to maintain their connected state. Thereby, as shown in fig. 1 and 2, the connector fitting of the waterproof connector structure 1 is performed. At this time, although the male terminal 2 and the female terminal 4 are positioned in the housing receiving space portion 32a and in the connector receiving space portion 51a, the partition wall 100 and the outer housing 32 are sealed by the second sealing member 33, and the outer housing 32 and the female connector 5 are sealed by the first sealing member 6, so that the penetration of liquid from the outside is restricted by the first sealing member 6 and the second sealing member 33, and the waterproof connector structure 1 is in a waterproof state.
As described above, according to the waterproof connector structure 1 and the connector fitting method of the waterproof connector structure of the present embodiment, it is possible to fix a part of the male connector 3, that is, the outer housing 32 before the male terminal 2 is received, to the partition wall 100 on the outside side of the partition wall 100. Therefore, the outer case 32 can be fixed to the partition wall 100 together with the second sealing member 33 before being configured as a part of the wire harness WH 1. Therefore, the time for the second sealing member 33 to be exposed to the outside is shorter than the time for the male connector 3 to be configured as a part of the wire harness WH1, since the time until the outer housing 32 is fixed to the partition wall 100. Therefore, the possibility of foreign matter adhering to the second seal member 33 and the like can be reduced, and the influence on the waterproof performance can be reduced. Further, since the time for exposing the second seal member 33 to the outside can be shortened, the time for managing the wire harness WH1 including the male connector 3 so as not to allow foreign matter to adhere to the second seal member 33 can be shortened at the time of assembling, and therefore, the workability of assembling the wire harness WH1 can be improved.
In addition, according to the waterproof connector structure 1 and the connector fitting method of the waterproof connector structure of the present embodiment, the male connector 3 can be fixed to the partition wall 100 on the outer side of the partition wall 100 without passing the wire harness WH1 through the through hole 100a of the partition wall 100. Therefore, the workability of assembling the wire harness WH1 can be improved. Further, since the wire harness WH1 is not inserted through the through hole 100a, the wires and the electronic components 200 constituting the wire harness WH1 do not contact the partition wall 100, and damage to the wire harness WH1 can be suppressed in handling of the wire harness when the wire harness WH1 is connected to the internal electronic device 300.
Further, according to the present embodiment, when the connectors of the male connector 3 and the female connector 5 are fitted, the terminal cover portion 35 is assembled to the inner housing body 34 in advance, and the tip end portion of each male terminal 2 is not exposed from the terminal cover portion 35, so that damage to the male terminal 2 at the time of fitting the connectors can be suppressed.
Further, as shown in fig. 1, the wire harness WH1 of the above embodiment may have the electronic component 200 larger than the through-hole 100 a. In this case, the wire harness WH1 cannot be introduced from the outside to the inside of the partition wall 100. Therefore, even in the wire harness WH1 having the electronic component 200 larger than the through hole 100a, the male connector 3 can be arranged on the outside of the partition wall 100. Thus, when the electronic component is divided into the outside and the inside via the partition wall 100, the wire harness WH1 of the electronic component 200 having the through-hole 100a larger than the through-hole can be electrically connected to the wire harness WH2 by connector fitting of the male connector 3 and the female connector 5.
In the above embodiment, the terminal cover portion 35 is a member different from the inner housing body portion 34, but is not limited thereto. The terminal cover portion 35 may be integrated with the inner housing main body portion 34.
In the above embodiment, the internal electronic device 300 is a battery, and the partner electronic device 400 is an inverter, but the present invention is not limited thereto. For example, when the partition wall is a door, the internal electronic device 300 may be a motor or a sensor disposed inside the door, and the counterpart electronic device 400 may be an ECU (electronic control unit) disposed inside the vehicle body and controlling these internal electronic devices.
