Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector, and more particularly, to a connector provided in a power supply line for supplying power to a device installed in an openable window or door of a vehicle.

[0002]

2. Description of the Related Art Some industrial vehicles such as power shovels have a structure in which a windshield of a driver's seat (cabin) can be opened and closed. In some cases, a windshield wiper device is mounted not on the vehicle body but on the windshield itself. FIG. 8A is a front view of the driver's seat of such an industrial vehicle as viewed from the windshield side.
FIG. 8B is a sectional side view of a main part of a driver's seat in the industrial vehicle shown in FIG. 8A.

[0003] A wiper device 52 is fixed to a windshield 51 attached to the front of the cabin 50. The wiper device 52 includes a wiper blade 53 and a motor unit 54 for driving the wiper blade 53. The motor unit 54 is mounted inside the windshield 51 (on the cabin 50 side), and the motor unit 54 and the wiper blade 5
3 is connected via a through-hole 51 a provided in the windshield 51.

When the windshield 51 is opened (that is, the windshield 51 is removed from the front of the cabin 50), the windshield 51 is pulled from the cabin 50, and is moved on a rail (not shown) mounted in the cabin 50. Slide in the direction of arrow A. As a result, the windshield 51 comes off the front surface of the cabin 50 and is stored in the ceiling portion (the portion B in the drawing) inside the cabin 50.

Power is supplied to the motor unit 54 by a power supply line 55 running in the cabin 50. However, if the motor unit 54 and the power supply line 55 are simply connected, when the windshield 51 is stored in the ceiling portion of the cabin 50, the power supply line 55 hangs down in the cabin 50 and hinders operation. If the length of the power supply line 55 is not enough, the power supply line 55 may be broken by forcibly pulling it.

Therefore, a connector 56 is provided in the middle of the power supply line 55.
(Note that in FIG. 8B, the power supply line 55 between the connector 56 and the motor unit 54 is denoted by an electric wire C). Then, the windshield 51 is moved to the cabin 50.
When the connector 56 is stored in the ceiling part, the driver himself disconnects the connector 56 into the male side 56a and the female side 56b. Conversely, when closing the windshield 51 (ie, attaching the windshield 51 to the front of the cabin 50), the driver himself inserts the male connector 56a into the female connector 56b.

[0007]

However, each time the windshield 51 is opened and closed, the driver himself / herself will need to connect the male connector 56a.
It is troublesome to attach and detach the female connector 56b.
If the user forgets to disconnect the connector 56 into the male side 56a and the female side 56b and opens the windshield 51,
An unreasonable force may be applied to the power supply line 55 to cause disconnection.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a connector having a simple structure that can be automatically attached and detached each time a window or a door is opened and closed. .

[0009]

SUMMARY OF THE INVENTION The present invention is directed to a connector provided in the middle of a power supply line for supplying power to a device installed in an openable window or door of a vehicle. The first connector fixed to the vehicle body and the second connector fixed to the vehicle body are arranged so as to be integrated when the window or door is closed, and further the first connector or the second connector is fixed. At least one of the contacts of the connector is a movable contact, in the direction of maintaining the contact between the contacts when disconnecting the two connectors, in the direction of avoiding the contact between the contacts when connecting the two connectors The gist of the invention is to provide an opening / closing speed increasing means for urging the movable contact and releasing the urging force after a predetermined urging force is stored to open and close the contacts.

According to a second aspect of the present invention, there is provided a connector provided in the middle of a power supply line for supplying power to a device installed in a window or door which can be opened and closed in a vehicle, wherein the first connector is fixed to the window or door. And a second connector fixed to the vehicle body are arranged so as to be integrated when the window or door is closed, and at least one of the first connector and the second connector One of the contacts is a movable contact, the movable contact is supported by a leaf spring having one end fixed, and the other end of the leaf spring has a direction of maintaining contact between the contacts when disconnecting the two connectors. When connecting the two connectors, the connector moves in a direction to avoid contact between the contacts, generates an urging force in the same direction on the leaf spring, and releases the urging force after a predetermined urging force is stored. Open and connected As its gist in that a knob for opening and closing between.

[0011]

According to the present invention, when the window or door is closed, the first connector and the second connector are closed.
Connectors are integrated. For this reason, both connectors can be automatically attached / detached each time the window or door is opened / closed. In addition, when detaching both connectors, when disconnecting both connectors, in the direction to maintain the contact between the contacts,

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will now be described with reference to FIGS.
This will be described with reference to FIG. In the present embodiment, the same components as those of the conventional example shown in FIG. 8 are denoted by the same reference numerals, and detailed description thereof will be omitted.

FIGS. 1A and 1B are sectional views showing a male connector 11a as a first connector of the connector 11 of the present embodiment. Note that FIG. 1A is a diagram illustrating the D-
It is D sectional drawing.

The male connector 11a includes a case 2 made of an insulating material (synthetic resin, ceramics, etc.) and a movable contact 3 made of a pin-shaped conductive material (metal, conductive resin, etc.).
a, 3b, compression springs 4a, 4b, and leaf springs 12a, 1
2b, E-rings 13a and 13b, a knob 14, and a compression spring 15.

The movable contacts 3a and 3b are connected to a motor unit 54 via an electric wire C. Each leaf spring 12a, 1
One end of 2 b is fixed to case 2. The end of each movable contact 3a, 3b (female connector 11b described later)
(The end opposite to the side in contact with the fixed contacts 6a, 6b)
Is connected to each leaf spring 12a by each E-ring 13a, 13b.
a, 12b. Each compression spring 4a, 4b
Is mounted between each leaf spring 12a, 12b and each movable contact 3a, 3b.

The compression spring 15 is provided between the case 2 and the knob 1.
When the male connector 11a is in a single state, the distal end of the knob 14 projects outside the case 2 by applying a biasing force to the knob 14. Each leaf spring 12a, 12b is provided at the end of the knob 14.
The protrusion 14a is provided at a position corresponding to.

In the state shown in FIG. 1, the knob 14 does not protrude further out of the case 2. In this embodiment, the opening / closing speed increasing means is constituted by the leaf springs 12a and 12b, the knob 14, and the compression spring 15.

FIG. 2 is a sectional view showing a female connector 11b as a second connector of the connector 11 of the present embodiment. FIG. 2 is a diagram of the female connector 11b viewed from a direction corresponding to the male connector 11a shown in FIG. The female connector 11b includes a case 5 and fixed contacts 6a and 6b.

Here, the male connector 11a is fixed to the window frame of the windshield 51 shown in FIG. 8, and the female connector 11b is fixed to the vehicle body in contact with the window frame of the windshield 51. The connectors 11a and 11b are fixed at positions where the male connector 11a is inserted into the female connector 11b and integrated when the windshield 51 is closed.

Therefore, when the male connector 11a is inserted into the female connector 11b, the movable contacts 3a and 3b and the fixed contacts 6a and 6b come into contact with each other. Then, the power supply line 55 → the fixed contacts 6a, 6b → the movable contacts 3a, 3
Power is supplied to the wiper device 52 through the route of b → wire C → motor unit 54.

When the male connector 11a is inserted into the female connector 11b, the knob 14 of the male connector 11a comes into contact with the end 5a of the case 5 of the female connector 11b.

FIG. 3 shows the connector 11 and the motor unit 5.
4 shows the connection relationship between the motor M in FIG. The power of the motor unit 54 is turned on / off by a switch S provided on the vehicle body side.

Next, the operation of the embodiment constructed as described above will be sequentially described with reference to FIGS. When closing the windshield 51, as shown in FIG. 4, before the movable contacts 3a, 3b and the fixed contacts 6a, 6b come into contact, the tip of the knob 14 and the end 5a of the case 5 come into contact with each other. .

At this time, the tip of the knob 14 comes into contact with the end 5a of the case 5 and is pushed up, so that the compression spring 15 is compressed. The projection 14a of the knob 14 is
A force is applied to the distal end portions H of the a and 12b from below. Therefore,
Each leaf spring 12a, 12b flexes upward to store a spring reaction force.

When the windshield 51 is further closed, as shown in FIG. 5, the male connector 1 is connected to the female connector 11b.
1a is completely inserted. At this time, the tip of the knob 14 comes into contact with the end 5a of the case 5 and is pushed up.
Over the tip H. Then, the distal ends H of the leaf springs 12a and 12b to which a force has been applied from below by the convex portion 14a of the knob 14 "bounce down" due to the stored spring reaction force. Accordingly, each movable contact 3a, 3b comes into contact with each fixed contact 6a, 6b.

Therefore, each of the movable contacts 3a, 3b and each of the fixed contacts 6a, 6b come into abrupt contact. Further, in a section from before the windshield 51 closes (the position where the knob 14 contacts the end 5a) to when the windshield 51 is completely closed, the open state of the contact portion is maintained. Therefore, even if the windshield 51 moves up and down when the windshield 51 is manually closed, chattering does not occur in the contact portions.

By the way, when the movable contacts 3a, 3b and the fixed contacts 6a, 6b come into slow contact with each other when the windshield 51 is closed, the movable contacts 3a, 3b and the fixed contacts 6a, 6b are connected. An arc can occur and the contact ends can be damaged. However, in the present embodiment, since the movable contacts 3a and 3b and the fixed contacts 6a and 6b come into abrupt contact as described above, no arc is generated and the contact ends are not damaged.

When the windshield 51 is completely closed, the leaf springs 12a and 12b bend upward to store the spring reaction force, and the tip of the knob 14 is connected to the end 5 of the case 5.
The compression spring 15 is compressed by being pushed up in contact with a. The convex portion 14a of the knob 14 is
b, no force acts between the convex portion 14a of the knob 14 and each of the leaf springs 12a, 12b.

Accordingly, each movable contact 3a, 3b is pressed against each fixed contact 6a, 6b by a contact pressure corresponding to the spring reaction force of the leaf springs 12a, 12b. Therefore, even when there is a slight shift in the mounting position between the female connector 11b and the male connector 11a, the contact between the movable contacts 3a, 3b and the fixed contacts 6a, 6b is reliably maintained.

Next, when the windshield 51 is slightly opened,
As shown in FIG. 6, the upper outer edge F of the case 5 of the female connector 11b and the lower outer edge G of the case 2 of the male connector 11a.
Contact with is released.

At this time, the knob 14 is pushed down by the urging force of the compression spring 15, but since the tip of the knob 14 is in contact with the end 5a of the case 5, the knob 1
4a applies a force to the distal end portion H of each leaf spring 12a, 12b from above. Therefore, each leaf spring 12a, 12b bends downward to store a spring reaction force, and each movable contact 3a, 12b.
The contact between the fixed contact 3b and each of the fixed contacts 6a and 6b is maintained.

When the windshield 51 is further opened, FIG.
As shown in the figure, the female connector 11b and the male connector 11
It is completely separated from a. At this time, the contact between the tip of the knob 14 and the end 5a of the case 5 is released, so that the knob 14 is pushed down by the urging force of the compression spring 15, and
The protruding portion 14a jumps over the distal end portion H of each of the leaf springs 12a and 12b, and advances to below the distal end portion H. Then, the distal end portions H of the leaf springs 12a and 12b to which the force has been applied from above by the convex portion 14a of the knob 14 jump up in the direction of arrow I due to the stored spring reaction force. Accordingly, the movable contacts 3a and 3b are drawn into the case 2.

Accordingly, the contact between each of the movable contacts 3a, 3b and each of the fixed contacts 6a, 6b is rapidly cut off. by the way,
When the windshield 51 is opened and the power is supplied while the wiper device 52 is operating, the movable contacts 3a and 3b
When the fixed contacts 6a and 6b are slowly separated from each other, an arc is generated between each of the movable contacts 3a and 3b and each of the fixed contacts 6a and 6b, and the contact ends may be damaged. But,
In this embodiment, as described above, since the contact between each of the movable contacts 3a, 3b and each of the fixed contacts 6a, 6b is suddenly interrupted, no arc is generated and the contact end is not damaged. .

Further, from the position where the windshield 51 starts to open, the convex portion 14a of the knob 14 is connected to each leaf spring 12a, 1a.
In a section until the tip end H of the movable contact 2b is passed, the closed state of each of the movable contacts 3a and 3b and each of the fixed contacts 6a and 6b (hereinafter, referred to as a contact portion) is maintained. Therefore, even if the windshield 51 moves up and down when the windshield 51 is manually opened, chattering does not occur in the contact portion.

As described above, in this embodiment, by providing the leaf springs 12a and 12b, the knob 14, and the compression spring 15, the movable contacts 3a and 3b and the fixed contacts 6a and 6 are provided.
The contact speed with b (contact opening / closing speed) can be increased. As a result, according to the present embodiment, each movable contact 3a, 3
Since no arc is generated between the contact b and the fixed contacts 6a and 6b, the effect of preventing damage to the contact end can be obtained.

In this embodiment, the male connector 11a is fixed to the windshield 51, and the female connector 11b is fixed to the vehicle body. Then, when the windshield 51 is closed, the male connector 11a is automatically inserted into the female connector 11b and integrated therewith. When the windshield 51 is opened, the female connector 11b and the male connector 11a are automatically disconnected.

Therefore, it is not necessary for the driver to detach and connect the male connector 11a and the female connector 11b each time the windshield 51 is opened and closed, and there is no trouble as in the conventional example. When the windshield 51 is opened, the power supply line 5
Since an unreasonable force is not applied to 5, the disconnection can be prevented.

The above embodiment is not limited to the above embodiment, but may be implemented as follows. By setting the negative side of the power supply line 55 to the body ground, each movable contact 3a, 3b (each fixed contact 6a, 6
One of b) is omitted. -One of the leaf springs 12a and 12b is omitted. -The mounting positions of the male connector 11a and the female connector 11b are reversed. That is, the female connector 11b is fixed to the windshield 51, and the male connector 11a is fixed to the vehicle body. A member corresponding to the compression springs 4a and 4b is provided in the female connector 11b instead of the male connector 11a. One of the compression springs 4a and 4b is omitted, and the corresponding movable contacts 3a and 3b are fixed to the case 2. -The compression springs 4a and 4b are replaced with appropriate types of springs (for example, leaf springs, tension springs) instead of coil springs. -The leaf springs 12a and 12b are replaced with an appropriate type of spring (for example, a coil spring). The present invention is applied not only to the wiper device 52 but also to a connector of a power supply line of another device. The present invention is applied to a connector of a power supply line for supplying power not only to the windshield 51 but also to a device fixed to a rear glass or a door. -Combine the above-mentioned alternatives as appropriate.
