Description

[Detailed description of the invention] (Industrial application field) Automatically and detachably connects the input/output terminals of the measuring instrument to the electronic device under test placed on a pallet positioned on a conveyor using an external mechanical drive. The present invention relates to a coupling device for

(Prior Art) In order to check the performance of semi-finished electronic equipment etc. on a conveyor, the input/output cable of a measuring instrument is automatically connected to the electronic equipment to be measured using a movable arm.

(Problems to be Solved by the Invention) However, there have been cases where accurate connection has not been made due to misalignment between the electronic device and the measuring instrument.

(Means for solving the problem) The present invention uses an inner member to which a measuring device terminal is attached.
It is held by a spring provided on the outer member.

(Function) Even if there is a misalignment when connecting the terminal attached to the inner member and the electronic device on the pallet,
The spring expands or contracts due to the lateral pressure applied to the inner member due to the positional deviation, and the position of the inner member relative to the outer member is shifted to prevent undue force from continuing to be applied to the terminal portion. When the terminal is disconnected, the spring pressurizes it so that it returns to a normal position near the center.

(Embodiment) FIG. 1 shows a sectional view of an embodiment of the present invention, and FIG. 2 shows a sectional view taken along line A-A'. 1 is the outer member,
2 is a screw for installing the spring and adjusting the spring pressure; 3 is a lock nut for locking the screw 2; 4 is a spring; 5 is a cover for the outer member 1; 6 is an inner member that can be moved relative to the outer member; 7 is an inner member. This is the terminal mounting plate No. 6. Reference numeral 11 indicates a bearing to facilitate the movement of the inner member 6; 12 indicates a ball that serves as a contact point when the inner member 6 is kept approximately in the center by the spring 4; and 14 indicates a limiter pin that works together with the groove 13 to move the inner member 6. This is a limiter pin to limit the rotation direction. The back surface 16 of the outer member 1 is attached to a movable arm of a measuring instrument (not shown),
Connection terminals for inputting and outputting signals of the measuring instrument are fixed to the mounting plate 7.

The operation of the above configuration will be explained. FIGS. 1 and 2 are diagrams when the inner member 6 is in a normal position, and show a state in which the forces received by the inner member 6 are balanced and stable by balls located on the upper, lower, left, and right sides. If there is an axis misalignment in the rotational direction between the connection terminal (not shown) of the terminal mounting plate 7 of the inner member 6 and the input/output terminal on the electronic equipment side on the pallet, the inner member 6 will rotate in the rotational direction as shown in Fig. 3. Because of the deviation, the connecting terminals of the measuring instrument and the power equipment can be connected to each other without applying excessive force. When the connection is released, the restoring force of the spring 4 applied to the inner member 6 returns it to the normal position shown in FIG. Even if a force exceeding the limit of the ability to restore the inner member 6 from deviation in the rotational direction is applied, the limiter pin 14 and the groove 13 described above
engages to limit rotation. In this way, when the movable arm of the measuring device is pushed out by an external mechanical drive to connect the terminals to the electronic device placed on the positioned pallet, even if there is a slight misalignment of the axis, no unnecessary force is applied to the terminal part. Electrical connections can be made reliably without any problems. In the above embodiment, the outer shape of the inner member 6 is circular, but by configuring the outer member 1' and the inner member 2' in a square shape as shown in FIG. As shown in the figure, it can be provided with a stopper function. Note that by attaching stopper pins 20 to each side as desired, the limits in each of the upper, lower, left, and right directions can be individually and variably set.

(Effects of the invention) When connecting inspection signals, etc. to electronic equipment on the conveyor, it is possible to absorb variations in positioning accuracy on the conveyor and ensure reliable connection without applying excessive force to each terminal on the electronic equipment side or measuring instrument side. Electrical connection can be obtained.
