[Detailed Description of the Invention] [Summary] Regarding the insertion/extraction mechanism of a one-sided connector of a unit in which a connector is attached to both opposing end pieces, the insertion/extraction direction is perpendicular to the end pieces, the insertion/extraction force of both opposing connectors is The purpose of this method is to connect connectors on one side of a relay terminal board with the plug or jack side of the connector attached to both opposing ends, with the aim of improving productivity by preferentially inserting and removing only the connector located on one side. In the insertion/removal mechanism of the opening-side connector of the device, the connector is attached such that the part thereof is exposed from the opening of the housing, and the relay terminal board is arranged such that the distance between the opposing wall surfaces is equal to the thickness of the relay terminal board and the thickness of the connector. It has a U-shape in side view that is slightly larger than the sum of the two walls, and a window large enough to cover at least the connecting part of the connector on the bottom part connecting both walls thereof, and a protrusion protruding outward near the end hidden by the opening. A lever formed with a lever is provided near the open side connector between the protrusion and the end of the protrusion side connector so that it can freely rotate with respect to the relay terminal plate with an axis orthogonal to the relay terminal plate. and configure it.

[Industrial application field]

The present invention relates to a mechanism for attaching a connector to a unit, etc.
In particular, in a unit in which a connector is installed on both opposing end pieces, the insertion/extraction direction is perpendicular to the end pieces, the productivity is increased by allowing only one connector to be inserted/extracted with priority, regardless of the insertion/extraction force of both opposing connectors. The present invention relates to a connector insertion/extraction mechanism with improved performance.

For example, information processing equipment is composed of multiple units such as the main body, input/output devices such as displays, printers, and keyboards, and control devices for these devices, but interface signal cables are usually used to connect each unit. has been done.

However, in special cases, various units may be directly connected to the main body, and in such cases, a detachable relay terminal board may be used instead of the signal cable.

In particular, in this case, the relay terminal board is equipped with connectors whose insertion/extraction direction is perpendicular to the end pieces on both opposing end pieces, and these two connectors connect the main body and various units via the relay terminal plate. Often, when a unit connected to the main body is separated from the main body, the connector with the weaker insertion and removal force of the relay terminal board is removed first.

However, depending on the application, it may be desirable to remove a specific connector, so there is a desire to develop a means for preferentially removing only one connector, regardless of the insertion/extraction force.

[Prior Art] FIG. 3 is a conceptual diagram showing an example of the configuration of the main parts of a conventional device, in which (a) is an overall configuration diagram, and (b) is a diagram illustrating a coupling means of the device.

In FIGS. 3(a) and (b), 1 indicates the main body of the device, and 1
0 represents a connection unit connected to the main body 1 of the apparatus.

This device main body 1 is composed of a power supply unit 2, a storage device 3, and a main printed board unit 4 that controls input/output signals of the device main body 1, and each of these units has an output port for input/output signals. It is fixed with a stay 6 at a predetermined position inside a casing 5 having an opening 5a.

Note that square holes 5b for positioning and holding the connecting unit 0 are formed at two predetermined positions above the opening 5a on the surface of the housing 5 where the opening 5a is formed.

In addition, 7 in the figure shows a relay terminal board that leads the input/output signals of the printed board unit 40 fixed to the inner part of the housing 5 to the vicinity of the opening 5a of the housing 5. For example, the relay terminal board 7 equipped with connectors 8a and 9a made of plugs can be connected to the printed board unit 4 by inserting one connector 8a into the connector 8b made of a jack mounted on the printed board unit 4. At the same time, the other connector 9a is connected to the connection unit 10.

On the other hand, in the connection unit 10 that transfers information to the main body work of the apparatus, a sub printed board unit 11 connected to the control unit lla is housed inside a housing 12 having a similar opening 12a at a position corresponding to the opening 5a. Although it is fixed in a predetermined position with a stay 6 similar to the above, the printed board unit 11 has a plug attached to one end of the relay terminal plate 7 exposed through the opening 12a and connected to the main body 1 of the apparatus. A connector 9b consisting of a jack is disposed at a position corresponding to the connector 9a.

Further, at a position corresponding to the square hole 5b of the housing 5 on the surface where the opening 12a of the housing 12 is formed, a claw 12b is inserted into the square hole 5b to hold the housing 12 and thus the connection unit 10.
is fixed and protrudes outward.

Therefore, the relay terminal plate 7 is inserted from the connector 88 side through the opening 5a of the device main body 10 along the guide (not shown) as shown by the arrow a.
When inserted as shown, the connectors 8a and 8b are connected, and the input/output signals of the printed board unit 4 can be led to the connector 9a of the relay terminal board 7 located near the opening 5a.

Next, when hooking the claw 12b of the housing 12 into the square hole 5b of the housing 5 as shown by the arrow C, the state shown in FIG. By moving it, the jack side connector 9b of the printed board unit 11 on the housing 12 side can be inserted into the plug side connector 9a of the relay terminal board 7, and as a result, the device main body 1 and the connecting unit 0 are connected. can do.

Also, move the connecting unisolated eye O in the opposite direction C' to
2b from the square hole 5b, the device main body 1 and the connection unit 10 can be separated.

In such a case, the connectors 8a, 8b and 9a, 9b that connect the relay terminal board 7 at both ends thereof are usually the same product;
This means that the removal force between connectors 9a and 9b, that is, between the relay terminal plate 7 and the connection unit 10, is equal to the removal force between the connectors 9a and 9b, that is, between the device main body 1 and the relay terminal plate 7.

Therefore, when the connecting unit 10 is moved in the C' direction in order to remove it from the device main body 1, it is not possible to determine which connector will be separated first. If the connectors 9a and 9b are removed first, the relay terminal board 7 will be connected to the printed circuit board unit 4 as shown in Figure (b), so there will be no particular problem. If the connectors 8a and 8b connecting between the connecting unit 10 and the connectors 8a and 8b are removed first, the relay terminal plate 7 moves as the connection unit 10 rotates, as shown by the broken line d, and comes into contact with a guide, etc. (not shown), and the relay terminal plate You can't get rid of 7.

Therefore, conventionally, connectors 9a and 9b connecting the relay terminal plate 7 and connection unit 0 are connected to the device main body and the relay terminal plate 7.
However, measures such as using a different type of connector with a smaller insertion/extraction force than the connectors 8a and 8b used to connect the
As the number of connector pins increases, it becomes impossible to cope with the problem.

[Problems to be Solved by the Invention] In the conventional connector insertion/extraction mechanism, the type of connector connecting between the device main body and the relay terminal board and the connector connecting between the relay terminal board and the connection unit must be changed, which makes production difficult. There is a problem that no improvement in performance can be expected, and there is also a problem that it is becoming difficult to cope with the increase in the number of connection pins.

[Failure to solve the problem]

The above problem is caused by the opening-side connector of a device in which the connector on one side of a relay terminal board, in which the plug or jack side of the connector is attached to both opposing end pieces, is exposed through the opening of the housing. The insertion/extraction mechanism is such that the relay terminal board is U-shaped in side view, and the distance between the opposing walls is slightly larger than the sum of the thickness of the relay terminal board and the thickness of the connector, and at least the above-mentioned A lever is formed with a window large enough to cover the connection part of the connector and a protrusion protruding outward near the end hidden by the opening, and the protrusion and the connector end on the protrusion side are placed near the opening side connector. This problem is solved by a connector insertion/extraction mechanism that is configured to be attached to the relay terminal plate so as to freely rotate around an axis perpendicular to the relay terminal plate provided between the connector and the relay terminal plate.

[For production]

If a mechanism for forcibly separating a connected connector is installed around the connector, the connector can be separated or removed with priority regardless of the insertion/extraction force.

In the present invention, by installing a connector insertion/extraction mechanism that is linked to the movement of the connection unit coupled to the device main body around the connection unit side connector of the relay terminal board, the connector can be removed when the connection unit is moved. The connector is designed to connect between the terminal board and the connection unit.

Therefore, there is no need to change the type of connector that connects between the device main body and the relay terminal board and the connector that connects between the relay terminal board and the connection unit, and it is also possible to cope with an increase in the number of connection pins.

〔Example〕

FIG. 1 is a block diagram showing an example of the connector insertion/extraction mechanism according to the present invention, and only the main parts of FIG. 3 are extracted and shown.

Moreover, FIG. 2 is a diagram explaining the extraction operation.

In each figure, the same objects as in FIG. 3 are indicated with the same symbols.

In FIG. 1, reference numeral 5 designates the housing of the device main body 1 explained in FIG. The connection portion of the plug connector 9a located on the side is exposed.

In this case, near the connector 9a, the distance e between the opposing wall surfaces 15a and 15b is equal to the thickness of the relay terminal plate 7, which is 1. The lever 15 has a U-shape in side view that is slightly larger than the sum of the thickness t2 of the connector 9a and the bottom surface 15c thereof is formed with a window 15d large enough to cover at least the connecting portion of the connector 9a. The lever 1 is inserted through the spacer 16 and the relay terminal plate 7 as shown in the A-A' cross section (1-1) at one place near the end piece excluding the part.
It is rotatably attached to the relay terminal plate 7 by a shaft 17 fixed to the terminal plate 5.

Note that 18 in the figure is a washer that smoothes the rotation of the lever 15 relative to the relay terminal plate 7.

Further, a protrusion 15e projecting outward is formed near the end of the bottom surface 15c of the lever 15 on the side where the shaft 17 is attached and which is hidden by the opening 5a.

Therefore, when the protrusion 15e is pressed, the lever 15 rotates about the shaft 17 in the direction shown in the figure f, but when the projection 15e is not pressed, the lever 15 maintains the same positional relationship as in FIG. 3(b). .

On the other hand, 12 indicates the housing of the connection unit 10 explained in FIG. 3, and the connection part of the connector 9b on the jack side attached to the printed board unit 11 is exposed in the opening 12a as in FIG. ing.

Therefore, the connection unit 10 is connected to the main body l in the state shown in the figure.
By attaching the connectors as explained in FIG. 3, the jack side connector 9b can be inserted into the plug side connector 9a, so that the apparatus main body 1 and the connection unit 10 can be connected as a result.

FIG. 2 is a plan view explaining the extraction operation, and (A) shows a state in which the device main body 1 and the connection unit 10 of FIG. 1 are combined.

In Figures 2 (A) and (B), 5 and 12 indicate the casing;
9a and 9b represent connected connectors, 7 represents a relay terminal board, and 15 represents a lever.

When the connection unit 10 is moved in the direction C'' in FIG. 3 in order to remove the connection 22) 10 from the device main body l, the insertion/extraction force between the connectors 9a and 9b is increased as shown in FIGS. 1 and 3. If the insertion/extraction force between the connectors 8a, 8b is even slightly greater than the illustrated insertion/extraction force, the connectors 8a, 8b will separate in the removal direction, and the relay terminal plate 7 will move together with the connection unit 10, but the protrusion 15e of the lever 15 will As explained in FIG. 1, since the lever 15 is pressed by the inner wall surface of the housing 5, the lever 15 rotates in the f direction about the shaft 17 as shown in FIG. 1B.

As a result, the tip end portion 15f of the lever 15 presses against the shoulder surface of the connector 9b.

In particular, since the relationship between the distance from the shaft 17 of the lever 15 to the protrusion 15e and the distance L2 from the shaft 17 to the tip edge portion 15f is Ll<L2, the movement I of the protrusion 15e
There is S+ between S1 and the amount of movement S2 of the tip edge portion 15f.
<'Sz holds true.

Therefore, after the tip edge portion 15f comes into contact with the shoulder surface of the connector 9b, the tip edge portion 15f presses the connector 9b in a direction to separate it from the connector 9a, so that the two are forcibly separated.

Furthermore, if the insertion/extraction force between the connectors 9a, 9b is even slightly smaller than the aforementioned insertion/extraction force between the connectors 8a, 8b,
Since the relay terminal plate 7 is removed from the connector 9b of the connection unit 10, the device main body 1 and the connection unit 10 can be separated without any trouble.

Note that the device main body 1 to which the connection unit 10 is not connected
When attaching or detaching the relay terminal plate 7, it can be easily done through the opening 5a of the housing 5 by rotating the lever 15 as indicated by g to the approximately 90-degree raised position indicated by the two-dot broken line f. .

In the above explanation, connector 8a is used for ease of understanding.
, 9a is on the plug side and connectors 8b and 9b are on the jack side, but connector 8a,
The connector 9a can be used as a jack side and the connectors 8b and 9b can be used as a plug side.
It is clear that the same effect can be obtained even if the combinations are different, such as by attaching the jack side connector 9b and the jack side connector 9b.

〔Effect of the invention〕

As described above, according to the present invention, in a unit in which a connector is attached to both opposing end pieces and whose insertion/extraction direction is perpendicular to the end pieces, priority is given to only one connector regardless of the insertion/extraction force of both opposing connectors. It is possible to provide a connector insertion/extraction mechanism that improves productivity by allowing the connector to be removed by the connector.

Although the present invention has been described with reference to the case where the main body of the device and the connection unit are connected by a relay terminal board, the same effect can be obtained even if the relay terminal board is replaced with a relay control unit or the like having a relay function. Obtainable.
