DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for conducting a test or heat treatment by connecting a connector of an object to a connector of an apparatus for performing a test or heat treatment and supplying power or a signal to the object. Regarding the connector attaching / detaching device used, for example, I
It is advantageously used for a constant temperature bath, which is a device for burn-in performed to eliminate latent defective products in semiconductor products such as C.

[0002]

2. Description of the Related Art An environmental test apparatus such as a thermostat is equipped with a connector in a test chamber. When testing a DUT, the DUT is installed in the test chamber and the connector is connected to a connector in the test chamber. In some cases, an environmental test can be performed while supplying a power supply or an operation signal to the device under test. In the case of manually attaching and detaching the connector in such an environmental test apparatus, there are problems such as poor workability due to the small size of the test chamber, troublesome attachment / detachment operations, and difficulty in reliable attachment / detachment. .

[0003] An integrated circuit device (IC), which is a typical example of a test object to be tested by connecting a connector, is mounted on a large number of test sockets mounted on a printed wiring board generally called a burn-in board. It is put into a test room together with the burn-in board, and is tested in an operation state where power and signals are applied through the burn-in board. For this reason, the burn-in board usually has an edge formed at the tip end in the insertion direction, and the edge is inserted into an edge connector fixedly arranged in the test chamber, whereby the electrical connection between the burn-in board and the power supply or signal generation source is made. Connection is achieved.

[0004] Burn-in of an IC is generally performed in a high-temperature atmosphere using a constant-temperature bath called a burn-in chamber in order to apply a larger stress to the IC than in a normal use state. The edge connectors are arranged in a single row or multiple rows at the back side in the tank. At the time of a burn-in test, a large number of burn-in board edges are inserted into and extracted from these edge connectors (hereinafter referred to as "insertion / extraction"). I do. However, since there are a large number of burn-in boards and a considerable force is required to insert and remove the edge of one burn-in board, a great deal of labor is required to insert and remove the edge by human operation. In particular, in monitor burn-in tests and test burn-in systems, in addition to power supplies and signals,
Electrical connection for measuring the operation state of the IC is also required, the edge connector is multipolarized, and the insertion / extraction force of the edge is increased in proportion to this, and it is becoming difficult to insert / extract by human power. .

To cope with such a problem, there has been proposed an apparatus which inserts and removes a burn-in board by mechanical force (Japanese Patent Application Laid-Open Nos. 61-265579 and 61-2655).
No. 80, 62-2176, JP-A-2-251778, etc.). However, in these devices, a mechanism such as an arm that makes a revolving motion or a pusher that makes a reciprocating motion is provided outside the width of the burn-in board so as not to hinder the insertion and removal of the burn-in board so that the insertion and removal force is transmitted to the burn-in board. Therefore, it was necessary to increase the width so that these could be arranged, and the burn-in chamber became large.

As an apparatus which can attach and detach a connector of a multi-stage burn-in board with a simple mechanism of only linear movement, four air cylinders are arranged at upper, lower, left and right positions on the back of a constant temperature bath to reciprocate an insertion / extraction frame. At the same time, there has been proposed an apparatus in which a single air cylinder moves an insertion / extraction frame up and down and synchronizes these operations so that a square-shaped operation is performed to attach / detach a connector (Japanese Unexamined Patent Application Publication No. Hei 8 (1999)). -1
No. 36613).

[0007] However, even with this device, the number of air cylinders and the like is large and the cost is high, the size of the device is large due to the large occupied space in the device, the operation control and its adjustment are difficult, and the back of the thermostat is difficult. The system wiring is installed, so the maintainability of machines and mechanisms such as air cylinders is not good.The air cylinders are located on the back of the equipment, so that they have special heat-resistant specifications. It has various problems, such as poor performance, and the system wiring itself is also restricted by the rear equipment of the air cylinder.

[0008]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems in the prior art, occupies a small space, uses a small number of driving motors, is simple in operation control and adjustment, has good maintainability, and has good installation work. In particular, it is an object of the present invention to provide a connector attaching / detaching apparatus capable of saving labor in a burn-in test of a semiconductor product as an object without increasing the size of a thermostat or the like. Make it an issue.

[0009]

[0011]

FIG. 1 shows an example in which a connector attaching / detaching apparatus to which the present invention is applied is applied to a burn-in chamber comprising a high-temperature constant temperature bath. This burn-in chamber has a heat insulating wall 1
00, a heat insulating door 101, a test chamber 102 formed by being surrounded by these elements, a blower (not shown) for circulating air in the test chamber, a heater for heating circulating air, and the like. The burn-in boards 1 that can be mounted are arranged in multiple stages. On the back side of the test chamber, edge connectors 2 as fixed connectors for supplying power and signals from the outside are fixedly arranged in multiple stages in the vertical direction via connector mounting rods 3. The edge connector 2 is connected to the outside via a relay board 4. The connector mounting rod 3 to which the edge connector 2 is mounted is connected to the test chamber 10 by a screw 3a.
2 is fixed to the inner wall 100a.

In the above description, the case where the relationship between the connector and the fixed connector is an edge and an edge connector is shown. On the contrary, when the connector is an edge connector and the fixed connector is an edge, It is needless to say that the present invention can be applied to other connector structures such as the case where the relationship is a male-female connector.

Each of the burn-in boards 1 inserted in multiple stages in the vertical direction incorporates a large number of IC sockets 5 as shown in the figure, and ICs 6 as semiconductor products are mounted on these IC sockets 5. The IC 6 is electrically connected to the edge 7 via the internal wiring of the IC socket 5 and the burn-in board 1. Therefore, in this example, IC6
The burn-in board 1 and the edge 7 mounted thereon correspond to an object and a connector fixed to the object, respectively.

The burn-in board 1 is connected in a direction in which a connector is attached and detached by a groove of a groove member 9 fixed in multiple stages in a vertical direction of a support rod 8 erected in a test chamber 102 (in the present embodiment, the following will be described). It is supported so as to be movable in an attaching / detaching direction (hereinafter, referred to as “insertion / extraction direction” in the present embodiment) indicated by an arrow YY ′ which is a “insertion direction” and a separating direction (hereinafter, referred to as “extraction direction”) in the present embodiment. You. Therefore, the support rod 8 and the groove member 9 correspond to the support means. Reference numeral 10 denotes an insertion / extraction unit.

As shown in FIG. 1 (b), which is a view of the burn-in board 1 when viewed from below, the corners of the front end thereof, the upper printed circuit board 1c and the upper printed circuit board 1c, It is formed by fixing the lower plate 1d with screws. The edge 7 for electrical connection is formed on the front end side of the printed circuit board 1c and protrudes from the reinforcing frame 1a, but is fixedly supported by such a structural portion. A part of the lower plate 1d is notched, and a recess 1e is formed between the notch and the reinforcing frame. In the figure, the reinforcing frame 1a is on the front end side in the burn-in board insertion direction, and the reinforcing frame 1b is on the end in the width direction. In this structure, the inner surface 1a ₁ and the outer surface 1a ₂ of the reinforcing frame 1a is a respective one-side contact surface and the other side engagement portion for forming a connector detachably to the contact surface.

The burn-in board usually has a recess 1e.
Is not formed, but the burn-in board used in the burn-in chamber of this embodiment is processed so as to form a concave portion. However, such processing is very easy and almost no extra cost is generated. In addition, even when using an existing burn-in board, it can be easily modified in this way,
Since the cost is very small, there is no problem in applying the present invention. Further, a burn-in board having no lower plate 1d can be used as it is.

FIG. 2 shows an example of the structure of the insertion / extraction unit 10 of the burn-in board 1 with respect to the edge connector 2. Although these are provided symmetrically in FIG. 2A, the illustration of the left side of the center line C is omitted. The insertion / extraction unit 10 includes a claw plate 11 as a detachable member, an elevating shaft 12 as a moving member, an air cylinder 13 as a moving means, a link 14, an upper guide plate 15a and a lower guide as one side and the other side guide portions. Board 15
b, etc. In this embodiment, a spring 16 is provided as an example of a suppressing unit. Reference numeral 17 denotes a connecting plate that connects the left and right nailed plates 11 to form a frame. When the connecting plate 17 is provided in this manner, the rigidity of the claw plate 11 is increased, and the elevation of only one side of the left and right elevating shafts 12 is suppressed, and the influence on the burn-in board 1 at the time of malfunction is avoided. However, the structures may be simplified independently of each other.

As shown in FIG. 3, the claw-attached plate 11 is a member for inserting and removing the edge 7 from the edge connector 2, has a claw surface 11a and an opposite surface 11b, and moves in the Y-Y 'insertion and removal direction. The claw surface 11a or the opposite surface 11b
Is the inner surface 1a of the reinforcing frame 1a of the burn-in board 1, respectively.

′ And Z-Z ′ direction, and is moved up and down.
d and a mounting portion 11e. In this example, the claws face upward in this example, but they may be directed downward and the opposite surface 11b may be positioned below. or,
You may make it affix a buffer member to these parts.

The elevating shaft 12 is guided so as to be movable in the vertical ZZ 'direction in this embodiment as a direction substantially perpendicular to the YY' direction which is the insertion / extraction direction. Reference numeral 12a denotes an appropriate number of brackets fixed to the structure of the main body. Appropriate mechanisms such as rollers, linear guides, and slide guides are attached to these brackets, and the elevating shaft 12 moves only in the ZZ 'direction. It is supported and guided as follows.

The air cylinder 13 is arranged on the ceiling outside the heat insulating wall 100, and reciprocates the elevating shaft 12 guided through the heat insulating wall in the ZZ 'direction. In this example, one unit is provided independently for each of the left and right elevating shafts 12 (the left side is not shown). However, a structure in which only one is provided at the center and the movement is transmitted to both sides by an arm or the like may be adopted. As the moving means, instead of an air cylinder, a hydraulic or electric type, a mechanism using a cam mechanism, a mechanism combining a screw shaft and a nut rotated by a motor, a mechanism for performing a linear movement by a combination of a crank and a link For example, various suitable linear reciprocating driving devices can be used.

The air cylinder 13 is actuated by compressed air supplied from a compressed air source provided in a factory or the like via an electromagnetic valve or the like. The solenoid valve or the like is provided with a mechanism for adjusting the piston speed of the air cylinder as needed. By the supply of the compressed air, a predetermined movement is given to the air cylinder 13, and the lifting shaft 12 can be moved up and down and stopped at a predetermined timing, position and speed. Further, it is also possible to detect that the burn-in board is installed at a predetermined position and to automatically perform such an operation.

In this embodiment, as described later, the lower position P ₁ and the upper position P
₂ and an intermediate position P ₃ are provided, and sensors S ₁ , S ₂ and S ₃ are arranged to detect the piston positions. In this example, an example is shown in which the air cylinder 13 is arranged on the ceiling when the moving member is an elevating shaft. However, when a machine room is provided at the lower part of the apparatus main body, a linear driving means such as an air cylinder is provided. Of course, it is also possible to arrange in that part.

In this embodiment, a plurality of links 14 are provided at the top and bottom, and the link 14 connects the lifting shaft 12 and the claw plate 11 in a substantially parallel relationship. An example of this connection state is shown in FIGS. That is, the lifting shaft 12
And one end 14a of the link 14 are rotatably connected to each other by a pin 12b and retaining rings 12c and 14b, and the mounting portion 11e of the claw plate 11 and the other end 14b of the link 14 are connected. The pin 11f and the retaining ring 1
4c, 11g and the spacer 14d are connected so as to be rotatable with each other. As a result, the claw plate 11 is connected so as to be parallel to the elevating shaft 12 and the distance y is variable.

The upper guide plate 15a guides the claw plate 11 in the YY 'direction, which is the insertion / removal direction. In this embodiment, the other end 1 of the upper end link 14 (14-1) of the links 14 is used.
4b is slidingly guided. However, the spacer 14d may be formed as a rotatable color ring so as to protrude from the link 14, and this portion may be rotated and guided. Conversely, the width of the spacer 14d is made wider and smaller, and a ridge is provided on the upper guide plate 15a.
4d may be contacted. By such a method, the claw plate 11 is connected to the pin 1 connected to the link 14.
The upper limit position is guided in the YY ′ direction via 1f.

As shown in FIG. 5, the lower guide plate 15b guides the claw plate 11 in the YY 'direction in the same manner as the upper guide plate 15a. The pin 11f is extended at the other end 14b to provide a color ring 11h, which is guided below. Note that the width of the spacer 14d is increased so that the retaining rings 11 on both sides are increased.
g, 14c are made larger than this, and the lower guide plate 1
The upper end of 5b may be a ridge portion, and these portions may be brought into contact. By such a method, the claw plate 11 is guided in the YY ′ direction at the lower limit position via the pin 11f in the same manner as in the case of the upper end link.

In FIG. 5B, the lower link 14 (14
2B), the one shown by the two-dot chain line above the one shown by the solid line is the upper link 14 (14-
1) shows a state in which (1) is guided in contact with the upper guide plate 15a. That is, the upper and lower guide plates 15a and 15b
The position of the other end side 14b of the link is guided at both ends of a predetermined width z in the vertical ZZ 'direction, and the upper and lower limit positions of the claw plate 11 are set and guided.

FIG. 6 shows another example of the upper and lower guide plates 15a and 15b. In the present example, the upper and lower guide plates 15a, 15
b is formed integrally with one guide plate 15,
This is disposed at the other end 14b of one of the upper and lower links 14, and a color ring 11h is interposed between the upper and lower portions. Further, in this embodiment, the movement of the ring 11h is further restricted so that the displacement amount of the other end 14b of the link in the YY ′ direction is the distance s. As shown by a two-dot chain line in FIG. 2A, the link 14 may be disposed on both sides of the elevating shaft 12 as 14 and 14 '. In this case, the resultant force of the link driving force coincides with the axis of the elevating shaft, and the link driving operation can be performed more smoothly.

In the above description, the upper and lower guide plates 15a, 15
b guides the other end side of the link, but an appropriate guided portion is provided at the upper and lower ends and intermediate positions of the claw plate 11,
This portion may be guided by a guide plate.

The spring 16 shown in FIG.
The expansion of the angle formed by the link 14 is suppressed.
That is, the lifting shaft 12 is guided so as to move only in the ZZ 'direction, while the link 14 is connected to the link 14 at an appropriate angle.
2, the link 14 is rotated clockwise in FIG. 2 by its own weight and the angle is increased when the claw plate 11 is vertically oriented parallel to the elevating shaft as shown in FIG. Try to enlarge. On the other hand, the spring 16
The tension T pulls the claw plate 11 toward the elevating shaft 12 side, and causes the link 14 to have a moment TLcos θ (L is the center-to-center length of the link, θ is the distance between the elevating shaft 12 and the link 14). Angle), and the counterclockwise moment suppresses the angle expansion of the link.

The spring 16 comprises an elevating shaft 12 and a claw plate 11.
Are fixed to the support pins 16a and 16b attached to the support pins 16a and 16b. In this case, in the example of FIG. 2B, when the elevating shaft 12 moves up and down, the length of the spring 16 changes and the mounting angle to the support pin also changes due to the change in the vertical position. Therefore, the support pins 16a and 16b are rotatably mounted in accordance with the change in the angle of the spring 16, or, for example, as shown in FIG. It is desirable to lock the spring end in such a manner.

FIG. 8 shows another example of the mounted state of the spring 16. In this example, two springs 16 are locked at one end 14a of the link with an interval from the elevating shaft 12, and their free ends are locked to the pressing plate 16c. Is applied with a pressing force of 2T. In this case, assuming that the distance between the contact point 16d between the link and the pressure plate and the support center 14i of the link is d, 2Td
, And can act on the link.

This moment changes in accordance with the rise of the elevating shaft 12 because T and d change when the elevating shaft 12 rises. However, when the moment approaches the position shown by the two-dot chain line, this moment decreases rapidly. Becomes 0. Therefore, when the link rises, the ascending direction of the other end 14b tends to be inclined, the ascending speed of the other end 14b becomes gentler, and the direction of collision with the upper guide plate 15a is inclined from 90 °. . As a result, the effect of reducing the impact force and smoothing the movement of the other end in the YY ′ direction is produced.

Although the spring 16 is a tension spring in the example of FIG. 8, an opposing pressing plate (not shown) is fixedly arranged on the opposite side of the pressing plate 16c from the spring 16, and the spring is placed between the two pressing plates. A spring may be used as a compression spring. By doing so, the length and spring force of the spring can be freely selected.

In the above description, the case where the angle suppressing means is a spring using a tension or a compression force such as a coil spring has been described. For example, the lifting shaft 12 and the lifting shaft 12 A torsion spring or the like interposed and locked between the link 14 may be provided. Further, instead of the spring, an appropriate sliding is provided between the lifting shaft 12 and the link 14 or between the link 14 and the pin 12b or 11f to apply a frictional force to the angular displacement of the link to perform a braking action. A member may be interposed.

It is to be noted that it is desirable that the nailed plate 11 is originally light in weight, but this is made of such a material, the number of loading stages of the burn-in board 1 is small, and the elevating distance is smaller than the lateral moving distance. If you want to design,
It is also possible to use a friction torque or the like inevitably present in the link and omit the special angle suppressing means. Further, in an apparatus such as a burn-in board that stores an object in an upright state and the moving member and the attaching / detaching member extend in a lateral direction, the angle suppressing unit can be omitted.

FIGS. 9 and 10 show a method of inserting and removing a connector of a burn-in board in the above-described burn-in chamber. In FIG. 9, only one edge 7 of the burn-in board and one claw portion 11 c of the claw plate 11 are shown for easy understanding of the operation description.
Further, the claw portion 11c and the edge 7 which are located on the back side of the paper surface with respect to the attachment portion 11e of the claw-equipped plate are represented by solid lines.
The description will be made with reference to FIG. 9 and other drawings. In addition, as shown in this figure, the claw-equipped plate 11 and its mounting portion 11e may be provided separately.

When the burn-in board 1 is inserted into all the steps of the groove member 9 up to the position immediately before the insertion of the edge, the operation of inserting the edge 7 into the edge connector 2 is performed automatically or manually. 9 (a) and 10 (b), the claw portion 1 indicated by a solid line.
The position 1c shows an initial state before the edge 7 is inserted into the edge connector 2. At this time, the claw portion 11c is located below the moving range of the burn-in board 1 when the edge 7 of the burn-in board 1 is inserted into and removed from the edge connector 2. Therefore, the insertion of the burn-in board 1 is not prevented.

Although not shown, the claw portion 11c is located at a position where it does not interfere with the burn-in board one step below. Claw part 11
The position of c in the YY ′ direction is, as shown, the lower position P ₁ of the piston 13a of the air cylinder 13 and the lower guide plate 15b.
, The nailed plate 11 and the link 1 that hit it
It is determined by the dimensions of 4. In this state, each of the distance between the lower plate 1d of (the show (b)) and burn-in board inner surface 1a ₁ claw surface 11a and the tip and the reinforcing frame that has become p and q.

When the air cylinder 13 is actuated and the elevating shaft 12 is raised as shown in FIG.
And lift it up and away from the lower guide plate 15b. At this time, the link 14 receives a moment in the direction of maintaining the angle with the elevating shaft 12 by the spring 16, pulls the claw plate 11 toward the elevating shaft 12 while maintaining the angle, and raises the plate in this state. Claw surface 11 at this time
The position a is the position indicated by the two-dot chain line above the solid line in FIG. In this state, the claw surface 11a and the frame inner surface 1
a ₁ and the engagement relationship.

The moment TL due to the spring force T
When the cos θ is smaller than the moment WLsin θ due to the own weight W of the claw plate 11 separated from the lower guide plate 15b, the claw plate is opened while the angle of the link 14 is opened corresponding to the difference between them and the rising speed of the lifting shaft 12. 11 rises.
However, since the distance q between the tip of the claw portion 11c and the concave portion 1e of the burn-in board 1 is small, the claw portion 11c does not hit the reinforcing frame 1a on the distal end side and enters the concave portion 1e.

When the air cylinder 13 further rises from the state (b), the other end 14b of the link 14 is guided by the upper guide plate 15a, and the rotation angle of the link 14 is increased against the tension of the spring 16. And the claw plate 11 is moved up and down
Move in the direction away from 2. When the piston 13a of the air cylinder as the (c) reaches the upper position P _2, the sensor S ₂ stops the detecting operation of the air cylinder so. In this position, the link 14 is substantially horizontal.

As a result, the claw surface 11a becomes p + p in the Y direction.
Moved by the distance ', it draws the inner surface 1a ₁ of the frame to insert a distance of p'edge 7 in the edge connector 2.
In this way, the connectors of all the burn-in boards inserted and supported in multiple stages can be connected at once by mechanical force. Then, the burn-in board 1 and the relay board 4 are electrically connected, and a burn-in test can be performed.

During this operation, the angle of the link 14 is opened and the claw plate 11 moves away from the elevating shaft 12, but when the claw surface comes into contact with the inner surface of the frame to push the edge 7, the elevating shaft 12 is moved. Furthermore, since the frictional force is generated between the two members due to the strong pressing force, the contact between the two members is not released and the claw plate 11 does not fall.

When the air cylinder operates in the opposite direction from the state (c) and the elevating shaft 12 starts to descend, before reaching the state (d), the link 14 is first inclined and the plate 11 with the claw is moved.
Is pulled toward the elevating shaft 12 side, and the press-contact state between the claw and the frame is released. As a result, no external force is applied to the frame when the claw plate 11 is lowered. Therefore, there is no possibility that the burn-in board is deformed and the circuit and the like formed thereon are adversely affected. When the claw plate 11 is lowered together with the other end 14b of the link, its lower end is supported by the lower guide plate 15b. In the example of FIG. 5 and the like, the other end of the link is supported, so that the claw plate 11 coupled to the pin 15f is supported.

When the piston descends and reaches the intermediate position P ₃ shown in (d), the sensor S ₃ detects this and stops the operation of the air cylinder. At this time, the nailed plate 1
The position of the opposite surface 11b of the claw portion 1 is the position of the elevating shaft 12,
Although determined by the position of the lower guide plate 15b, the dimensions of the link, and the like, in this example, the outer surface 1a of the reinforcing frame of the burn-in board is used.
It is just before position ₂ . Further, the tip of the claw is also located at a position retracted downward from the recess 1e of the burn-in board.

In this state, if necessary, the connector connection of an arbitrary burn-in board can be released and taken out. As a result, if an error occurs in some of the burn-in boards in the pre-check performed before executing the burn-in, the burn-in board can be removed once, taken as an error countermeasure, and then re-inserted.
One of the important functions in the burn-in test is satisfied.

When the burn-in board 1 is taken out of the chamber after the required burn-in time has elapsed, the step of removing the edge 7 is executed manually or automatically. That is,
The piston further descends from the state of (d). As a result, the angle of the link 14 is reduced, and the claw plate 11 is drawn toward the lifting shaft 12. When the initial piston lower position P ₁ indicated by sensor S ₁ in (a) is detected, the air cylinder actuating stops. During this time, the opposite surface 11b of the claw portion pushes the outer surface 1a ₂ of the frame, is pulled out of the edge 7 from the edge connector 2. Then, it returns to the initial state of (a). At this time, the claw portion 11c is at the position retracted from the concave portion 1e, and the burn-in board having the IC to be tested next can be inserted.

According to the connector attaching / detaching device as in this embodiment,
Since the burn-in boards installed in multiple stages can be attached and detached at a time by mechanical force, it is possible to significantly reduce labor in the burn-in test. Further, the attachment and detachment of the connectors at all stages are performed uniformly and reliably, and troubles such as poor connection of the connectors do not occur. Then, the air cylinder is connected to the heat insulating wall 100.
It is located on the outside ceiling part of the, and the elevating shaft is guided inside, and the link and the claw plate for edge insertion and extraction are attached to this, and the whole is integrated as an insertion and extraction unit, so installation work is easy At the same time, inspection and maintenance of the air cylinder and various mechanisms in and around the ceiling are easy.

Further, one or two driving sources such as air cylinders are used.
Since it can be configured with a minimum number of units, the product cost is low and the internal installation space is not required due to the ceiling arrangement. As a result, the internal space such as a constant temperature bath can be effectively used, and the number of burn-in boards that can be mounted inside is maximized. On the other hand, if a thermostatic bath having the same number of burn-in boards is planned, the height can be reduced and the device can be downsized.

Further, since the air cylinder is disposed outside, it is not exposed to a high temperature environment of 200 ° C. inside the constant temperature bath. As a result, it is possible to use a normal and inexpensive air cylinder that is not a special one having heat resistance and is commercially available. This also improves the reliability of the air cylinder. Furthermore, the number of air cylinders is minimized, and the operation is automatically converted to the operation of connector insertion / removal via a link mechanism, so that timing adjustment with other driving sources is not required at all, so that operation control and The adjustment is very simple and the operating reliability of the device is also improved.

In the above, an example has been shown in which the connector attaching / detaching device is applied to a burn-in chamber. In such a case, as described above, the present invention exerts a very remarkable effect. However, this device is required to connect and disconnect the connector of the target object in a narrow space even in a normal environmental test device and other room temperature test rooms, where the workability is poor or when a large force is required It is extremely effective when the entire test system is automated, including the loading and unloading of objects. Therefore, the present invention is not limited to only the application to the burn-in device.

As described above, according to the present invention, according to the first aspect of the present invention, when the attaching / detaching direction is, for example, a horizontal direction, the driving source for providing a driving force for attaching / detaching the connector is a direction substantially perpendicular thereto. For example, moving means for reciprocating the moving member in the vertical direction is provided. The moving means may be any simple means such as an air cylinder capable of linear movement. In addition, since an object such as a burn-in board to which a connector is to be attached / detached has a certain dimension in the width direction, both ends thereof are usually objects to be moved. Usually, two sets of moving members are provided. Accordingly, moving means such as air cylinders corresponding to these are at most two.
The number is minimal, as a table is sufficient.

Since the attaching / detaching member for attaching / detaching the connector and the moving member are connected in a substantially parallel relationship by a plurality of links, the reciprocating movement of the moving member in the vertical direction is changed by the link. It is transmitted to the attachment / detachment member. At this time, the one-side and the other-side guides guide the attaching / detaching member in the attaching / detaching direction within the range of the given width in the up / down direction, so that the reciprocating movement of the moving member links the link while allowing the given up / down width. The detachable member is moved in the detachable direction through the member. As a result, the attachment / detachment member is reciprocated in the attachment / detachment direction, for example, in the lateral direction, and between them, an operation in, for example, a vertical direction is added as a direction substantially perpendicular thereto.

The predetermined width is determined so as to be between a position where the claw surface of the detachable member and the one-side contact surface of the object can be engaged and a position where the engagement is released. Therefore, the connector is connected when the attaching / detaching member moves in the mounting direction. On the other hand, when the attaching / detaching member moves in the opposite separating direction, the claw surface does not engage with the one-side contact surface, but the opposite surface and the other-side contact surface naturally engage. So the connectors are pulled apart. Therefore, the movement can be converted into a connector attaching / detaching operation only by providing a maximum of two linear driving means such as air cylinders.

According to such a connector attaching / detaching device, for example, burn-in boards installed in multiple stages as objects can be attached and detached at a time by mechanical force, so that significant labor saving can be achieved in a burn-in test. Further, the attachment and detachment of the connectors at all stages are performed uniformly and reliably, and troubles such as poor connection of the connectors do not occur.

Further, since the moving member only reciprocates, when it is arranged vertically, it can be arranged, for example, on the ceiling above the heat insulating wall of the thermostat. Then, the moving member, the link, and the attaching / detaching member can be integrated as a unit. As a result, the installation work of the connector attaching / detaching device is simple, and the inspection and maintenance of various mechanisms such as moving means and links in the ceiling portion and inside are facilitated.

Further, one or two driving sources such as air cylinders are used.
Since it can be configured with a minimum number of units, the product cost is low and the internal installation space is not required due to the ceiling arrangement. As a result, the internal space such as a thermostat can be effectively used, and the number of objects such as burn-in boards that can be mounted inside can be maximized. On the other hand, if a device such as a thermostat having the same number of objects is planned, the height can be reduced and the device can be reduced in size.

Furthermore, since an air cylinder or the like as a moving means can be arranged outside, it is not exposed to a high temperature environment such as inside a thermostat. As a result, an air cylinder or the like is not a special one having heat resistance, and a normal commercially available inexpensive product can be adopted. This also improves the reliability of the air cylinder and the like. Further, since the number of moving means is the minimum, the operation is automatically converted to the operation of connecting and disconnecting the connector via the link mechanism, and the timing adjustment with other driving sources is not required at all. And adjustment is very easy. Therefore, the reliability of the operation of the device can be improved.

According to the invention of claim 2, in addition to the above,
Since the suppressing means for suppressing the expansion of the angle formed by the link and the moving member is provided, the operation of the link and the attachment / detachment member can be further ensured.
