JP 2015-099719 A

The waterproof connector described in the above-mentioned Patent Document 1 may be provided with an electric wire clamping portion on the rear holder that clamps and holds the electric wire. In this case, when attaching the rear holder to the housing, the waterproof connector requires an insertion force for inserting the electric wire into the electric wire clamping portion in addition to the insertion force for inserting the one-piece rubber plug into the housing, and the increased insertion forces may increase the workload.

Therefore, the present invention was made in consideration of the above, and aims to provide a connector that can suppress an increase in the workload.

In order to solve the above-mentioned problems and achieve the object, the connector of the present invention comprises a terminal connected to an electric wire extending along an axial direction, a main body portion that holds the terminal and is fitted to a mating connector, a housing provided in the main body portion and having an opening for drawing the electric wire to the outside, a rear holder that closes the opening when the electric wire is drawn to the outside of the housing, and an elastically deformable gasket that is provided in the rear holder and has an insertion hole through which the electric wire can be inserted and that seals the opening when the electric wire is inserted into the insertion hole, and the rear holder is configured such that the gasket is integrally molded. The gasket is configured to include a first divided body that is fixed to the opening of the gasket, and a second divided body that is divided from the first divided body, the first divided body including a fixing portion that fixes the gasket, a fitting portion that is provided on the opening side of the fixing portion and has a recess formed in a concave shape, the second divided body is fitted into the recess, and a first electric wire clamping portion that is provided in the recess of the fitting portion, and the second divided body has a second electric wire clamping portion that is provided opposite the first electric wire clamping portion in a direction that intersects with the axial direction when fitted into the fitting portion, and that clamps and holds the electric wire together with the first electric wire clamping portion.

The connector of the present invention presses the first division, which has an integrally molded packing, into the opening of the housing to make the opening waterproof, and furthermore, clamps and holds the electric wires by fitting the second division into the fitting portion of the first division. This allows the connector to distribute the pressure force for pressing the first division into the opening of the housing and the fitting force for fitting the second division into the fitting portion, so that the workload when closing the opening of the housing with the rear holder can be distributed, and as a result, an increase in the workload can be suppressed.

The connector 1 according to the embodiment will be described with reference to the drawings. The connector 1 is fitted to a mating connector 100 provided in a vehicle, for example, and electrically connects an electronic device connected to the connector 1 with an electronic device connected to the mating connector 100. The connector 1 has a water-stopping function, and is designed to suppress an increase in the workload when assembling parts to realize the water-stopping function. The connector 1 will be described in detail below.

As shown in Figures 1 to 6, the connector 1 includes a terminal 10, an electric wire 20, a housing 30, a lever mechanism 40, a rear holder 50, a packing 60, a first locking mechanism 70, and a second locking mechanism 80.

In the following description, of the first, second, and third directions that intersect with each other, the first direction is referred to as the "axial direction X", the second direction is referred to as the "width direction Y", and the third direction is referred to as the "height direction Z". Here, the axial direction X, width direction Y, and height direction Z intersect with each other and are typically perpendicular to each other. The axial direction X corresponds to the direction in which the electric wires 20 extend, the direction in which the connectors are inserted and removed, etc. The width direction Y corresponds to the direction along the width of the connector 1, the direction in which the electric wires 20 are lined up, etc. The height direction (intersecting direction) Z corresponds to the direction along the height of the connector 1, etc. Furthermore, unless otherwise specified, each direction used in the following description refers to the direction in which each part is assembled with each other.

As shown in FIG. 5, the terminal 10 is a female terminal made of a conductive metal material and is electrically connected to a mating terminal. The terminal 10 has an electrical contact portion that is electrically connected to the mating terminal, and an electric wire connection portion that is electrically connected to the end of the electric wire 20. The electric wire connection portion is electrically connected to the electric wire 20 by being crimped and attached to the conductor portion 21 of the electric wire 20.

As shown in FIG. 1, the electric wire 20 extends along the axial direction X and has a conductive conductor portion 21 and a coating portion 22 that insulates the conductor portion 21. The conductor portion 21 is made of a twisted wire in which multiple conductive metal wires (such as an aluminum alloy or copper alloy) are twisted together in a spiral shape, or a rod-shaped single-core wire. The coating portion 22 is made of, for example, an insulating synthetic resin. The electric wire 20 is electrically connected by crimping the conductor portion 21 at the end to the electric wire connection portion of the terminal 10.

As shown in FIG. 3, the housing 30 is made of an insulating material such as synthetic resin, and houses the terminals 10 and the like. The housing 30 has a main body 31, an opening 32, a pair of protrusions 33, 33, a slide portion 34, and a pair of claws 35, 35.

The main body 31 is formed in a cylindrical shape and has an internal space inside. The main body 31 accommodates the terminal 10 in a held state in the internal space. The main body 31 is open on one side in the axial direction X and on the other side in the axial direction X. The other side of the main body 31 in the axial direction X is fitted into the mating connector 100. At this time, the terminal 10 accommodated in the internal space of the main body 31 is electrically connected to the terminal of the mating connector 100.

The opening 32 is a portion where one side of the main body 31 in the axial direction X is open. The opening 32 is a portion through which the electric wire 20 passes when the electric wire 20 connected to the terminal 10 housed in the internal space of the main body 31 is drawn to the outside. In other words, the electric wire 20 connected to the terminal 10 housed in the internal space of the main body 31 is drawn to the outside through the opening 32.

The pair of protrusions 33, 33 serve as the pivot axis of the lever member 41 described below. The pair of protrusions 33, 33 are provided on the outer surface of the main body 31, and in this example, are provided on one side surface of the main body 31 and the other side surface of the main body 31 along the width direction Y of the main body 31, and each protrudes outward. The pair of protrusions 33, 33 are rotatably fitted into holes in the lever member 41.

The slide portion 34 is provided on the outer surface of the main body portion 31, and in this example, is located on the upper surface of one side of the main body portion 31 in the height direction Z. The slide portion 34 slidably holds the locking member 42, which will be described later, for fixing the rotational position of the lever member 41.

The pair of claws 35, 35 are for engaging the rear holder 50, which will be described later. The pair of claws 35, 35 are provided on the outer surface of the main body 31, and in this example, are provided on one side surface of the main body 31 and the other side surface of the main body 31 along the width direction Y of the main body 31, and each protrudes outward.

The lever mechanism 40 allows the connector 1 to be fitted to the mating connector 100 with a low insertion force. Here, the mating connector 100 includes a housing 103 that accommodates terminals, as shown in FIG. 2. The housing 103 has a fixed portion 102 that is fixed to an object such as a vehicle body, and a pair of protrusions 104, 104 that protrude from the housing 103 in the width direction Y. The fixed portion 102 has a hole through which a bolt 101 is inserted. The housing 103 is fixed to an object such as a vehicle body by inserting the bolt 101 through the hole of the fixed portion 102 and also through the object such as a vehicle body, and the bolt 101 is screwed with a nut. The pair of protrusions 104, 104 are engaged with the lever mechanism 40.

The lever mechanism 40 includes a lever member 41 and a locking member 42. The lever member 41 is attached to the housing 30 so as to be rotatable relative to the housing 30. For example, a pair of holes of the lever member 41 are fitted into a pair of protrusions 33, 33 of the housing 30, and the lever member 41 rotates around the pair of protrusions 33, 33 as a rotation axis. A pair of elongated holes 411, 411 are formed in the lever member 41, and a pair of protrusions 104, 104 of the mating connector 100 are fitted into the pair of elongated holes 411, 411. The lever mechanism 40 rotates the lever member 41 to one side with the pair of protrusions 104, 104 of the mating connector 100 engaged with the pair of long holes 411, 411, thereby moving the connector 1 along the axial direction X toward the mating connector 100 along the shape of the pair of long holes 411, 411. This allows the lever mechanism 40 to mate the connector 1 with the mating connector 100 with low insertion force. On the other hand, the lever mechanism 40 rotates the lever member 41 to the other side with the connector 1 engaged with the mating connector 100, thereby moving the connector 1 away from the mating connector 100 along the shape of the pair of long holes 411, 411. This allows the lever mechanism 40 to remove the connector 1 from the mating connector 100 with a small force.

The locking member 42 fixes the rotational position of the lever member 41 when the lever member 41 rotates and the connector 1 is mated with the mating connector 100. The locking member 42 is inserted into the slide portion 34 of the housing 30 and locks the lever member 41 after it rotates, thereby fixing the rotational position of the lever member 41.

As shown in Figs. 2 and 3, the rear holder 50 according to this embodiment closes the opening 32 when the electric wire 20 is pulled out to the outside of the housing 30. The rear holder 50 is formed of a synthetic resin or the like, and includes a first divided body 51 and a second divided body 52.

The fixed portion 63 is a portion that is fixed to the fixed portion 513 of the first divided body 51. The fixed portion 63 is a portion that is integrally molded with the fixed portion 513 of the first divided body 51 by injection molding of synthetic resin, and is fixed to the fixed portion 513. The packing 60 configured as described above waterproofs the opening 32 of the housing 30 when the electric wire 20 is inserted through the insertion hole 61.

The first locking mechanism 70 locks the first divided body 51 to the housing 30. The first locking mechanism 70 is composed of the pair of claws 35, 35 of the housing 30 and the pair of first hooks 516, 516 of the first divided body 51 described above. The first locking mechanism 70 locks the pair of first hooks 516, 516 to the pair of claws 35, 35 when the first divided body 51 is housed inside the housing 30. This allows the first locking mechanism 70 to prevent the first divided body 51 from slipping out of the housing 30 through the opening 32 of the housing 30 to the outside.

The second locking mechanism 80 locks the second divided body 52 to the first divided body 51. The second locking mechanism 80 includes the pair of claws 525, 525 of the second divided body 52 described above, the insertion space 521 of the second divided body 52, and the pair of second hooks 517, 517 of the first divided body 51. With the second divided body 52 engaged with the engagement portion 514 of the first divided body 51, the second locking mechanism 80 inserts the second hooks 517, 517 into the insertion space 521 of the second divided body 52 and locks them to the pair of claws 525, 525 in the insertion space 521. This allows the second locking mechanism 80 to prevent the second divided body 52 engaged with the engagement portion 514 of the first divided body 51 from coming off the engagement portion 514.

Next, an example of assembling the connector 1 will be described. The worker inserts the first divided body 51, with the packing 60 integrally molded, into the inside of the housing 30 from the opening 32 along the axial direction X. At this time, the worker inserts the first divided body 51 into the inside of the housing 30 while inserting the electric wire 20 into the insertion hole 61 of the packing 60, and accommodates the first divided body 51 inside the housing 30. Then, the worker engages a pair of first hooks 516, 516 provided on the first divided body 51 with a pair of claws 35, 35 provided on the housing 30, completing the assembly of the first divided body 51. Next, the worker inserts the second divided body 52 into the inside of the housing 30 along the axial direction X, and fits the second divided body 52 into the fitting portion 514 of the first divided body 51 accommodated inside the housing 30 along the axial direction X. As a result, the connector 1 holds the electric wire 20 by clamping it with the first electric wire clamping portion 515 of the first division 51 and the second electric wire clamping portion 524 of the second division 52, with the second division 52 fitted into the fitting portion 514 of the first division 51. Then, the worker inserts the pair of second hooks 517, 517 provided on the first division 51 into the insertion space 521 provided on the second division 52 and engages them with the pair of claws 525, 525 in the insertion space 521, completing the assembly of the second division 52.

As described above, the connector 1 according to the embodiment includes the terminal 10, the housing 30, the rear holder 50, and the packing 60. The terminal 10 is connected to the electric wire 20 extending along the axial direction X. The housing 30 has a main body 31 that holds the terminal 10 and is fitted to the mating connector 100, and an opening 32 provided in the main body 31 for drawing the electric wire 20 to the outside. The rear holder 50 closes the opening 32 when the electric wire 20 is drawn out to the outside of the housing 30. The packing 60 is an elastically deformable member that has an insertion hole 61 provided in the rear holder 50 through which the electric wire 20 can be inserted, and stops water from entering the opening 32 when the electric wire 20 is inserted into the insertion hole 61. In the above configuration, the rear holder 50 includes a first divided body 51 with which the packing 60 is integrally molded, and a second divided body 52 that is divided from the first divided body 51. The first divided body 51 includes a fixed portion 513, a fitting portion 514, and a first electric wire clamping portion 515. The fixed portion 513 fixes the packing 60. The fitting portion 514 is provided on the opening 32 side of the fixed portion 513, has a recess 514a formed in a concave shape, and fits the second divided body 52 into the recess 514a.

When the second divided body 52 is fitted into the fitting portion 514, it is provided opposite the first electric wire clamping portion 515 in the height direction Z intersecting the axial direction X, and has a second electric wire clamping portion 524 that clamps and holds the electric wire 20 together with the first electric wire clamping portion 515.

With this configuration, the connector 1 presses the first divided body 51, with which the packing 60 is integrally molded, into the opening 32 of the housing 30 to seal the opening 32, and further, the second divided body 52 is fitted into the fitting portion 514 of the first divided body 51 to hold the electric wire 20 by clamping it. As a result, the connector 1 can distribute the press force for pressing the first divided body 51 into the opening 32 of the housing 30 and the fitting force for fitting the second divided body 52 into the fitting portion 514, so that the workload when closing the opening 32 of the housing 30 with the rear holder 50 can be distributed. For example, the connector 1 can shift the timing of generation of the friction force between the packing 60 and the housing 30 and the friction force between the first electric wire clamping portion 515 and the second electric wire clamping portion 524 and the electric wire 20, and can distribute the workload. As a result, the connector 1 can suppress an increase in the workload.

In the above connector 1, the first divided body 51 is housed inside the housing 30. The second divided body 52 is fitted along the axial direction X into the fitting portion 514 of the first divided body 51 housed inside the housing 30. With this configuration, the connector 1 can fit the second divided body 52 into the fitting portion 514 of the first divided body 51 housed inside the housing 30.

In the connector 1, the first divided body 51 has a first protrusion 512 that protrudes from the outer surface of the first divided body 51 toward the inner surface of the housing 30. The second divided body 52 has a second protrusion 523 that protrudes from the outer surface of the second divided body 52 toward the inner surface of the housing 30. The first protrusion 512 and the second protrusion 523 abut against the inner surface of the housing 30 when the second divided body 52 is fitted into the fitting portion 514. With this configuration, the connector 1 can suppress rattling of the rear holder 50 consisting of the first divided body 51 and the second divided body 52. The connector 1 can also distribute the workload when suppressing rattling of the rear holder 50.

The connector 1 includes a first locking mechanism 70 that locks the first divided body 51 to the housing 30, and a second locking mechanism 80 that locks the second divided body 52 to the first divided body 51. The second locking mechanism 80 has an insertion space 521 and a pair of second hooks 517, 517. The insertion space 521 is provided in the second divided body 52, extends along the axial direction X, and has a pair of claws 525, 525 provided on the inside. The pair of second hooks 517, 517 are provided in the fitting portion 514, and extend along the axial direction X. With the second divided body 52 engaged with the fitting portion 514, the pair of second hooks 517, 517 are inserted into the insertion space 521 and locked to the pair of claws 525, 525. With this configuration, the connector 1 can prevent the second division 52, which is fitted into the fitting portion 514 of the first division 51, from coming off the fitting portion 514 by the second locking mechanism 80.

In the above description, the second divided body 52 is fitted into the fitting portion 514 of the first divided body 51 housed inside the housing 30 along the axial direction X. However, this is not limited to the above example. For example, the second divided body 52 may be fitted into the fitting portion 514 of the first divided body 51 along a direction different from the axial direction X.

The connector 1 has been described as having a first protrusion 512 and a second protrusion 523 that suppress rattle, but this is not limited thereto. For example, rattle may be suppressed by a configuration such as suppressing rattle with an elastic member.

The second locking mechanism 80 may be configured such that an insertion space 521 is provided in the fitting portion 514, and a pair of second hooks 517, 517 are provided on the second divided body 52, and when the second divided body 52 is fitted into the fitting portion 514, the pair of second hooks 517, 517 are inserted into the insertion space 521 and lock onto the pair of claws 525, 525.

The connector 1 can also be assembled to the housing 30 with the second division 52 already fitted to the fitting portion 514 of the first division 51.
