Abstract

PURPOSE:To separate a connector smoothly and certainly associate with opening of a plate by protrusively installing a pair of pins on the connector symmetrically about the plate width direction, and providing a hook to be engaged by the pins on the inside of the plate. CONSTITUTION:To couple a connector, a plate 6 mounted on a QD plate 4 pushes the end of a connector case 3, and the connector is pressed to the apparatus body concerned perpendicularly. At the time of separating, the QD plate 4 begins rotating, and in the condition that pins 1 and a Z-form metal piece 2 are contacting, drawing-off of the connector is started. In drawing off, the maximum force is required at the time of starting when a static friction force works, where the direction of the force which the Z-piece 2 acts on the pins 1 becomes identical to the direction of the connector being drawn off, and the direction of the contact surfaces is set so that it is free from any loss of the force and occurrence of hitches, etc. This enables lessening of the moment applied to the connector at the time of separation.

It is transmitted as a pulling force of this connector through 1, and this connector is pulled out and detached. A flange 04 is processed on the peripheral edge of the connector case 01, and the rotational force of the QD plate 02 is transmitted to the load point of the flange 04 to pull the connector case 01.

The concave portion of the QD plate 02 in which the flange 04 of No. 1 is housed is processed so that the upper portion and the lower portion have different depths. The depth of this concave portion is formed on the flange 4 only at a certain rotation angle of the QD plate 02. It is processed so that an appropriate load is applied. With such a mechanism, the rotational movement of the QD plate 02 is converted into a linear movement for pulling out the connector, and this connector is detached from the machine body.

[0003]

In the conventional connector as described above, the umbilical disconnection type connector is required to have absolute reliability in connection and disconnection functions. Since the joint and the load point are separated, a large moment is likely to be applied to the joint between the connector and the machine body. The load points that give the force to detach the connector are two points above and below, but the magnitude of the load applied to the two points above and below and the ratio of the load applied to the two points above and below change depending on the angle of rotation of the QD plate 02. Therefore, the moment around the connecting portion between the connector and the machine body changes in value depending on the angle at which the QD plate 02 is rotated, and particularly when the radius of the pullout direction between the pivot 03 and the connector is small, when the connector is detached. Since a large rotation angle is required, a large moment is applied to the connector, and the connector may be caught or deformed, so that the connector may not be detached smoothly.

In a connector device that is pulled out through a plate and detached from the machine body, a pair of pins symmetrically projecting from the connector in the width direction of the plate and an inner surface of the plate engaged with the pin. And a hook that moves with the opening of the plate and pulls out the connector.

[0005]

That is, in the connector device according to the present invention,
A plate mounted on the outside of the machine body is opened with one end as a fulcrum, and a connector attached to the machine body is pulled out through the plate to separate from the machine body. It is symmetrically projected and engages with the pin on the inner surface of the plate to provide a hook, which moves as the plate opens and pulls out the connector. By pulling out the connector by receiving it with the pin attached to the connector through the hook provided on the inside surface of the plate, the distance between the connecting point of the connector and the aircraft and the load point by the pin is shortened and the connector from the aircraft The moment applied to the connector when disconnected is small. Also, by properly setting the angle of the contact surface of the hook attached to the plate with the pin, the pin can be pulled at an angle close to the direction of pulling out the connector, and the moment applied to the connector when the connector is detached from the machine body is small. Become. Further, the load points applied by the pins are two symmetrical points of the connector, and the magnitude of the load applied to both load points is the same. As a result, the moments in the width direction of the plates, which are applied to the connection points between the connector and the machine body, are canceled with each other, and only the moments in the length direction of the plates become. Therefore, the moment applied to the connector when the connector is detached from the machine body is reduced.

1 and 2 are explanatory views of a connector according to an embodiment of the present invention. In the figure, the connector according to the present embodiment supplies electricity to the body of the rocket before launch,
A umbilical disconnection system connector that separates the rocket from the ground equipment when the rocket is launched. The QD plate (desorption plate) 4 with the pivot 5 as the center.
The mechanism is such that the rotation and rotation of the machine securely connects and disconnects the machine body. This connector is mounted on the QD plate 4 via the connector case 3, and when detached, the force due to the rotation of the QD plate 4 is transmitted as a pulling force for this connector through the connector case 3 to pull out this connector and detach it. The direction in which this connector is pulled out must be perpendicular to the machine body so as not to be caught or deformed in the connecting portion between this connector and the machine body. Therefore, in this connector, as shown in FIG. A pair of pins 1 are erected axially symmetrically with each other, and a Z metal fitting 2 is attached inside the QD plate 4. When the connector is detached, the Z metal fitting 2 pulls the pin 1 and pulls out the connector as the QD plate 4 rotates. Especially, even when the radius between the pivot 5 and the connector in the pulling direction is small, the connector can be pulled out without any problem. It can be pulled out and removed. It is necessary that slippage occurs between the contact surfaces of the pin 1 and the Z metal fitting 2 until the connector is detached from the machine body. Z hardware 2 along with rotation of QD plate 4
Although the center of the connector lowers downward, the connector case 3 needs to be pulled in the direction in which the connector is pulled out. Therefore,
When the rotation angle of the QD plate 4 changes, the contact surface between the pin 1 and the Z metal fitting 2 gradually shifts downward. In order to easily cause this deviation, the contact surface of the Z metal fitting 2 with the pin 1 and the pin 1 are treated by applying Teflon coating or the like to make them slippery. With such a mechanism, the rotational movement of the QD plate 4 is converted into a linear movement for pulling out the connector, and even if the radius in the pulling-out direction between the pivot 5 and the connector is small, the connector can be pulled out and separated from the machine body without any problem. It has become.

When the connector is connected, as shown in FIG.
When the end of the connector case 3 is pushed by the plate 6 attached to the QD plate 4, this connector is pushed vertically against the machine body to perform coupling. Also, when disconnecting this connector, QD
When the plate 4 starts rotating and the pin 1 and the Z fitting 2 are in contact with each other, the connector is pulled out, and the QD plate 4
The Z metal fitting 2 that rotates with the pin 1 of the connector case 3
The pulling operation of the connector is started by pulling.
Therefore, the pulling out of the connector requires the largest force at the start of pulling out due to the static frictional force. The direction of the contact surface of the Z metal fitting 2 with the pin 1 can be set so that there is no loss and no catching occurs. Specifically, the setting is made so that the contact surface of the Z metal fitting 2 with the pin 1 at the start of extraction is perpendicular to the direction (horizontal direction) in which this connector is extracted.

When considering the moment to be applied to the joint between the connector and the machine body with the load applied from the Z metal fitting 2 to the pin 1, the contact point between the pin 1 and the Z metal fitting 2, that is, the load point is the axis in the horizontal direction. There are two symmetrical locations. The distance from the connection point between this connector and the fuselage to the load point is the same in both places, and the magnitude of the load is the same regardless of the angle at which the QD plate 4 rotates, so the moments in the horizontal direction cancel each other out. It becomes zero when combined. This is the greatest feature that the moment is smaller than that of the conventional connector. In addition, the distance between the connection point of this connector and the machine body and the load point is shorter than that of the conventional connector, which is another factor that reduces the moment.

Although an umbilical disconnection-type connector is required to have absolute reliability in connection and disconnection functions, in the conventional connector, the connection between the connector and the fuselage and the load point are separated. Therefore, a large moment is likely to be applied to the connecting portion between the connector and the machine body. In particular, when the radius between the pivot and the connector in the pull-out direction is small, a large rotation angle is required when disconnecting the connector, so a large moment is applied to the connector and the connector is caught or deformed, resulting in a smooth connector. Although there is a possibility that it will not come off, in this connector, the rotational force of the QD plate 4 is received by the pin 1 attached to the connector case 3 via the Z metal fitting 2 inside the QD plate 4, so that the connecting point between the connector and the fuselage The distance between the load point by and pin 1 is shortened to reduce the moment applied to this connector when the connector is detached. Also, the QD plate 4
By properly setting the angle of the contact surface of the Z metal fitting 2 attached to the pin 1 with the pin 1, the pulling direction of the pin 1 can be made close to the pulling direction of the connector, and the connector is detached. The moment is reduced.
Also, the load points are two in the horizontal direction, and the magnitude of the load applied to both load points is equal. Therefore, the moments in the horizontal direction applied to the connection points between the connector and the machine body are canceled with each other, and only the moments in the vertical direction are left. As a result, the connector can be reliably pulled out even when the distance between the pivot 5 and the connector, that is, the radius in the pulling direction is as small as about 150 mm. Further, since the radius in the pull-out direction may be small as described above, the umbilical carrier including the QD plate 4 and the connector can be made small and lightweight, and the cost can be reduced. Moreover, the connector can be easily and reliably removed.

[0010]

The connector device according to the present invention is constructed as described above, and since the moment applied to the connector when the connector is detached from the machine body becomes small, the radius in the pull-out direction between the fulcrum of the plate and the connector is reduced. Even if is small, the connector can be disconnected smoothly and surely.
