The present invention relates to a clamp jig device, and more particularly, to a clamp jig device for ensuring an electrical connection between a flexible printed circuit board (flexible PCB) and a meter or other equipment.

Flexible printed circuit boards are often measured with a measuring instrument to determine whether the electrical signal transfer of the product can be made normally. In this case, the electrical connection must be made by contacting the terminals of the flexible printed circuit board and the test pins of the instrument. If a plurality of test pins are installed in the instrument, contacting them to the corresponding connection sites is simple and On the other hand, it is a difficult process. This is because the measurement task itself becomes meaningless if a large number of test pins are not in proper contact with the corresponding connection. Therefore, to accurately determine the disconnection, component defects, and operation status of a number of flexible printed circuit boards, connect the test pins of the instrument to the corresponding connection. There is a need for the use of jigs that can be quickly and simply contacted or detached from the site.

An object of the present invention is to provide a clamp jig that can quickly and accurately connect a flexible printed circuit board to test pins such as a measuring instrument.

Another object of the present invention is to provide a clamp jig in which the flexible printed circuit board can be held while the metrology operation is being performed.

A release button having a third diameter surface having an outer diameter excluding a portion of the diameter reducing portion passing through the horizontal through portion, and inserted into the horizontal through hole; A clamp jig device is provided.

According to a feature of the present invention, an elastic member is disposed between the clamp block member and the test pin block member so that the clamp block member is deflected in a direction away from the test pin block member.

According to another feature of the present invention, an elastic member is disposed in the horizontal through portion so that the release button can be deflected in a direction away from the test pin block member.

According to another feature of the present invention, the fourth diameter surface having an outer diameter larger than the outer diameter of the third diameter surface to prevent the release button is separated from the horizontal through portion to the inside direction of the horizontal through portion Is formed at the end of the release button.

According to another feature of the present invention, a screw portion is formed at the end of the slide shaft member to prevent the clamp block member from being separated from the test pin block member, and a nut is fastened to the screw portion.

According to another feature of the present invention, the diameter reducing portion coincides with the horizontal through portion when the flexible printed circuit board disposed on the test pin member is compressed by the indentation portion.

Hereinafter, with reference to the embodiment shown in the accompanying drawings of the present invention will be described in more detail.

1 is a perspective view of a clamp jig according to the present invention. The clamp jig 10 includes a test pin block 11 and a clamp block 13. The test pin block 11 is provided with three vertical passages 20 and 21 and one horizontal passage 22, and a press-fit groove 27 in which the test pin 12 is provided at one side is formed. Of the three vertical passages formed on both sides of the press-in groove 27 is the shaft passage 20, which penetrates the longitudinal direction of the test pin block 11. The passage formed in the rear surface of the press-fit groove 27 is a spring receiving portion 21 and the bottom surface is blocked. The horizontal passage 22 penetrates through the width of the test pin block 11 behind the press-in groove 27. The press-fit groove 27 is formed in a predetermined width and length on the front of the test pin block 11, the test pin 12 is provided on the bottom of the press-in groove 27. One end of the test pin 12 protrudes into the press-in groove 27, while the other end of the test pin 12 protrudes through the bottom of the test pin block 11 to electrically connect the instrument (not shown). (In the figure only one of the test pins is shown as protruding from the bottom of the block 11 but this is exemplary and the other test pins also protrude from the bottom of the block 11).

The clamp block 13 is provided with two slide shafts 14, a press-fitting portion 18 and a spring receiving portion 17 integrally. The area of the horizontal plane of the clamp block 13 preferably matches the horizontal area of the test pin block 11. The slide shaft 14 provided in the clamp block 13 has a threaded portion 16 formed at an end thereof, which is slidably inserted through a vertical passage 20 formed through the test pin block 11. It is preferable to prevent the clamp block 13 from being separated from the test pin block 11 by coupling the nut 25 to the threaded portion 16 protruding outward through the test pin block 11. The slide shaft 14 has a diameter reducing portion 15 formed at a predetermined height, and the diameter reducing portion 15 has a function of controlling the vertical movement of the clamp block 13 as described later.

The press-fitting part 18 integrally formed in front of the bottom of the clamp block 13 is slidably inserted into the press-fitting groove 27 formed in the test pin block 11. Moreover, the spring accommodating part 17 is formed behind the bottom of the clamp block 13. The spring 19 is inserted into the spring receiving portion 21 formed in the test pin block 11, the lower end of the spring 19 is in contact with the bottom surface of the receiving portion 21 of the test pin block 11, the spring ( The upper end of 19 contacts the upper portion of the receiving portion 17 of the clamp block 13. Therefore, the elastic force of the spring 19 deflects the clamp block 13 in the direction of disengaging from the test pin block 11.

The spring 23 is inserted into the horizontal passage 22 formed in the test pin block 11, and the release button 24 contacting both ends of the spring 23 has the horizontal passage on both sides of the test pin block 11. Is inserted in (22).

FIG. 2 shows the test pin block 11 of FIG. 1 as a plan view with a partial cross section, and FIG. 3 is an enlarged perspective view of the release button 24. As shown in FIG. As can be seen in FIG. 2, the release button 24 is inserted at both sides of the horizontal passage 22 around the spring 23, so that the release button 24 is subjected to the elastic force of the spring. . On the other hand, the horizontal passage 22 partially overlaps with the vertical passage 20.

Also, it can be seen from FIG. 3 that the release button 24 is formed of the first to fourth diameter surfaces 31, 32, 33, and 34. The outer diameter of the first diameter surface 31 and the fourth diameter surface 34 of the release button 24 substantially coincides with the inner diameter of the horizontal passage 22, while the second diameter surface 32 and the third diameter The outer diameter of the face 33 is smaller than the inner diameter of the horizontal passage 22. In addition, the outer diameter of the second diameter surface 32 is smaller than the outer diameter of the third diameter surface 33.

Referring again to FIG. 2, since the inner diameter of the vertical passage 20 (almost) coincides with the outer diameter of the slide shaft 14, the outer diameter surface of the slide shaft 14 rising and falling in the vertical passage 20 is a horizontal passage. The release button 24 can protrude to the outside by the elastic force of the spring 23 when it is in a position corresponding to the second diameter surface 32 of the release button 24 by being fitted to a part of the 22. none. That is, while the shaft 14 moves up and down while the outer diameter of the slide shaft 14 corresponds to the second diameter surface 32, the release button 24 maintains the state shown in FIG. This is because the outer diameter of the third diameter surface 33 cannot interfere with and pass through the outer diameter of the slide shaft 14.

On the other hand, as the slide shaft 14 moves up and down, the release button 24 may protrude to the outside when the diameter reducing portion 15 is orthogonal to the horizontal passage 22. That is, since the diameter of the diameter reducing part 15 indicated by the dotted line in FIG. 2 is not large enough to correspond to the second diameter surface 32, the release button 24 may protrude to the outside. The external protrusion of the release button 24 continues until the diameter of the diameter reducing portion 15 corresponds to the third diameter surface 33, and has a fourth diameter having an outer diameter larger than that of the third diameter surface 33. The face 34 interferes with the diameter of the diameter reducing portion 15 so that the release button 24 is prevented from fully exiting from the horizontal passage 22.

Next, the operation of the clamp jig device according to the present invention will be described.

The press fitting portion 18 of the clamp block 13 is inserted into the press fitting groove 27, and the slide shaft 14 is inserted into the vertical passage 20 so that the clamp jig device is assembled. The clamp block 13 is inserted into the spring receiving portion 21 so that one end thereof is upward from the test pin block 11 by the action of the spring 19 supported by the spring receiving portion 17 of the clamp block 13. Eccentric The nut 25 coupled to the end of the slide shaft 14 prevents the clamp block 13 from deviating from the test pin block 11.

When no external force is applied to the clamp block 13, the outer diameter of the slide shaft 14 passes through the horizontal passage 22, so the release button 24 maintains the state shown in FIG. That is, although the release button 24 is subjected to the elastic force of the spring 23, the head 35 remains in close contact with the side of the test pin block (11).

The flexible printed circuit board is inserted into the indentation groove 27 to be disposed below the indentation part 18. At this time, the connection portion of the flexible printed circuit board is in contact with the test pin 12. In order to fix the contact state, an external force is applied to the clamp block 13 so that the indentation unit 18 compresses the flexible printed circuit board against the test pin 12.

When the indentation 18 comes to a position where the flexible printed circuit board is pressed against the test pin 12, the position of the diameter reducing portion 15 formed in the slide shaft 14 coincides with the horizontal passage 22. Therefore, the release button 24 may protrude outward by the elastic force of the spring 23. The third diameter surface 33 of the release button 24 protruding outward corresponds to the diameter reducing portion 15 of the slide shaft 14 so that the slide shaft 14 is raised by the elastic force of the spring 19 or It can prevent falling by external force. Therefore, the press-fitting part 18 of the clamp block 13 can hold | maintain the flexible printed circuit board on the test pin 12, even if no external force is applied.

After the inspection of the flexible printed circuit board is finished, it should be separated from the test pin block 11. This action can be achieved simply by pressing the release button 24 towards the side of the test pin block 11. That is, when the release button 24 is pressed, the slide shaft 14 can be raised by the elastic force of the spring 19 because the second diameter surface 32 is aligned on the vertical passage as shown in FIG. have. When the clamp block 13 rises to the initial position, the operation of compressing the flexible printed circuit board is removed, so that the operator can remove the flexible printed circuit board from the indentation groove.

Clamp jig device according to the present invention is very convenient by making the electrical connection between the test pin and the connection with a simple action in the inspection adjustment operation of the flexible printed circuit board and other printed circuit board. These devices also have a wide range of applications for automation equipment.

Although the present invention has been described with the embodiments shown in the accompanying drawings, those skilled in the art will understand that various embodiments are possible therefrom. For example, even if there is only one release button, the clamp device of the present invention can fully function. Therefore, the true scope of protection of the present invention should be defined only by the appended claims.
