Description

Test Socket {TEST SOCKET}

The present invention relates to a test socket, and more particularly, to a test socket which can easily recover the FPCB after the test is completed, by preventing the connector portion from being damaged due to the FPCB being seated in a stable state easily, .

Flexible Printed Circuit Board (FPCB) is a flexible printed circuit board (hereinafter referred to as FPCB), which has been developed as electronic products have been miniaturized and lightweight, and has excellent workability, heat resistance, bending resistance and chemical resistance, Is widely used in cameras, computers and peripherals, handheld phones, video & audio equipment, camcorders, printers, DVD, TFT LCD, satellite equipment, military equipment and medical equipment.

However, the FPCB has a low mechanical strength and tears easily and is difficult to handle. Stiffener work is required to form a constant strength on the SMD and connector parts.

A manufacturing inspection for a flexible printed circuit board (FPCB) includes a display method for displaying a sample image only for a specific FPCB unit and an ICT method for detecting electrical characteristics on the circuit. To perform the test, the FPCB is loaded into the test socket after being loaded into the test socket.

In this regard, Korean Patent Registration No. 1357020 discloses a socket for testing electronic components. Patent Publication No. 1357020 discloses a base having an electronic part or a mounting part on which a terminal portion of the FPCB is seated; A lid rotatably coupled by a hinge shaft at an end of the base; And a hinge portion for providing a repulsive force between the base and the cover portion; A floating guide coupled to the base with a repulsive force and having a measuring pin at a position corresponding to the seating portion of the base at the bottom; An elastic spring or magnet for providing a repulsive force between the base and the floating guide; And a support pin extending from the base while being fixed to the base, the support pin passing through the guide hole of the floating guide and the other end being engaged with the upper portion of the floating guide.

Patent Publication No. 1357020 has a floating guide which is coupled to the base with repulsive force from the test socket so that the measuring pin under the floating guide can stably contact the terminal portion of the FPCB or the electronic part to be measured .

However, the registered patent publication No. 1357020 has a problem that breakage frequently occurs in the connector portion of the FPCB due to the disadvantage of the FPCB described above. That is, the FPCB, which is thin and easily bendable, tends to be seated in an unstable state (an excited state, a tilted state, or a rotated state) in the seat part even if the operator is careless. However, if the floating guide is lowered in this state, The connector portion is easily broken.

In order to solve the above-mentioned problem of Patent Publication No. 1357020, there is also used a method in which a permanent magnet is mounted on a seat portion and a stiffener made of SUS is brought into close contact with the seat portion by the magnetic force of the permanent magnet to prevent lifting of the connector portion , The SUS material does not significantly reduce the damage of the connector portion because it is difficult to form a strong attractive force to stick to the permanent magnet.

In addition, in the registered patent publication No. 1357020, since the floating guide is positioned just above the seat part to cover the view of the operator with respect to the seat part, there is a problem that it is difficult to confirm even if the FPCB is seated in the seat part in an unstable state.

The base 100, the seating member 200, the interference member 300, the cover 400, and the push member 500 can be easily recovered after completion of the test.

Hereinafter, for the sake of easy understanding of the present invention, the upper and lower portions will be described in a state shown in FIG. 1 (a state in which the cover 400 is closed).

As shown in Figs. 7 and 8, the base 100 is provided with a connection pin 101 connected to a terminal of an electronic component FPCB, and forms a rectangular parallelepiped block shape as a whole. The above-mentioned electronic component (FPCB) means FPCB.

Of course, the test socket 10 of the present invention can also be used for testing a general PCB. The base 100 is formed with a plurality of holes H into which bolts (not shown) are inserted. The base 100 is secured to the table of the test equipment (not shown) by bolting.

Preferably, the connection pin 101 is provided as a pogo pin and electrically connects the FPCB that is seated on the seating member 200 with the test equipment. The connecting pin 101 is installed in the pin mounting member 120 in the longitudinal direction. The pin mounting member 120 is disposed below the seating member 200.

The seating member 200 is a structure on which the electronic component FPCB is mounted and is movably installed in the base 100 so as to come close to or away from the connection pin 101. [ In the base 100, an installation space 102 in which a block-shaped seating member 200 moves in the longitudinal direction is formed.

7 and 8, a first elastic member S1 is interposed between the seating member 200 and the pin mounting member 120. As shown in Fig. The seating member 200 is pressed toward the side away from the connecting pin 101, that is, upward by the first elastic member S1.

A step 220 is formed at the edge of the seating member 200. The stepped portion 220 is brought into close contact with the boundary portion 103 of the base 100 by the force of the first elastic member S1 when the cover 400 is opened.

As shown in Fig. 8, a connector C having terminals is attached to the bottom surface of the end portion of the FPCB, and a stiffener T is attached to the upper surface of the end portion of the FPCB.

The FPCB is an original plate of a circuit board on which a flexible copper foil (copper film) is bent, and various surface mount devices are mounted in a specific area. At this time, the FPCB should reinforce the rigidity of the area in which the surface mount element is mounted. To this end, a metal or epoxy stiffener T is attached to the opposite surface of the FPCB on which the surface mount element is mounted.

As shown in FIGS. 2 and 3, a partition wall 230 is formed at an upper portion of the seating member 200 to surround the rim of the electronic component (FPCB). The stiffener T of the FPCB is prevented from rotating by the partition wall 230. [ A seating surface 201 on which the bottom surface of the FPCB is seated and an inserting portion 202 into which the connector C is inserted are formed inside the upper partition wall 230 of the seating member 200.

3 and 4, the interference member 300 is configured to prevent the flow of the electronic component (FPCB) placed on the seating member 200, and is movable in the horizontal direction on the upper surface of the base 100 Respectively.

The upper surface of the base 100 is provided with a restricting member 110 forming a boundary of the horizontal movement section of the interference member 300. The restraint member 110 is bolted to the upper surface of the base 100.

The left portion of the interference member 300 is referred to as the " front portion " of the interference member 300 and the right portion of the interference member 300 is referred to as the interference member 300 Quot; rear portion " of FIG.

The restricting member 110 forms a moving space 113 between the upper surface of the base 100 and the upper surface of the base 100 in a state where the restricting member 110 is bolted to the upper surface of the base 100. The rear portion of the interference member 300 is disposed inside the movement space 113. [ The interference member 300 is pressed toward the path PA by the second elastic member S2 provided inside the moving space 113 (so as to selectively invade the path PA on which the electronic component FPCB is placed).

3 and 4, the interference member 300 is formed with an interface 301 and the confining member 110 is formed with a confining surface 111. The restricting surface 111 forms the boundary of the movement section of the interference member 300 by the pressing force of the second elastic member S2 in a state in which the interface 301 is in close contact.

As shown in Fig. 8, the interference member 300 is moved along the path (in which the interface 301 is brought into close contact with the interface 301) by the pressing force of the second elastic member S2 (PA).

In the front portion of the interference member 300, a sloping surface 303 that forms a downward slope toward the front is formed. The lower end of the sloping surface 303 is located above the seating surface 201.

8, since the interference member 300 invades the path PA on which the electronic component FPCB is placed, when the operator lower the FPCB along the path PA, the force by which the operator descends the FPCB Is transmitted to the interference member (300) through the slope surface (303). The interference member 300 is pushed in the direction in which the second elastic member S2 contracts in the process of the FPCB descending along the path PA.

9, when the FPCB is seated on the seating surface 201, the interference member 300 is positioned on the upper side of the stiffener T by the pressing force of the second elastic member S2, The path PA is again invaded. The stiffener T may be provided with a stepped portion at which the lower end of the sloping surface 303 is caught (while the interference member 300 invades the path PA again).

As shown in Fig. 9, the connector C and the connection pin 101 are spaced apart in the longitudinal direction in a state in which the FPCB is seated on the seating surface 201. As shown in Fig.

7 to 9, the seating member 200 is formed with a pusher 210 pushing the electronic component FPCB in a direction opposite to the path PA on which the electronic component FPCB is mounted. The pusher 210 is configured to include a pushing pin P and a fourth elastic member S4.

A longitudinal hole is formed in the seating member 200 and the pushing pin P is pressed upward by the fourth elastic member S4 in a state where the pushing pin P is inserted in the hole in the longitudinal direction. The upper end of the pushing pin (P) protrudes upwardly on the seating surface (201). The fourth elastic member S4 is mounted to the seating member 200 or the pin mounting member 120. [

As shown in Figs. 7 and 8, the upper end of the pushing pin P maintains a state of protruding upward from the seating surface 201 until the FPCB is seated on the seating surface 201. Fig. 9, when the FPCB is seated on the seating surface 201, the upper end of the pushing pin P is pressed by the FPCB and positioned on the same plane as the seating surface 201. [

As shown in Figs. 1 and 2, the cover 400 is mounted on the base 100 in a rotatable or movable manner, such that the cover 400 approaches or moves away from the upper surface of the base 100. The cover 400 is provided with a push member 500 and a blocking member 600.

Referring to FIG. 2, in one embodiment of the present invention, a cover 400 is shown rotatably mounted on a base 100. Although not shown in detail, the cover 400 and the base 100 are relatively rotatably engaged by a cover pin (not shown).

Referring to FIG. 2, when the cover 400 is rotated approximately 90 degrees with respect to the base 100, the cover 400 is caught by the base 100 to prevent further rotation. A torsion spring (not shown) is mounted on the cover pin. The cover 400 is pressed in the direction in which the cover 100 is widened from the base 100 by the torsion spring.

The cover 400 is provided with a latching portion 410 and the base 100 is provided with a lever L which is engaged with the latching portion 410. The lever L is rotatably coupled to the base 100 by a pin (not shown). A torsion spring is mounted on the pin, and the lever L has a rotational force that rotates in a direction in which the lever L is engaged with the engaging portion 410 by the torsion spring.

As shown in FIG. 1, the lever L and the engaging portion 410 form a binding force by engaging with each other when the cover 400 closes the upper portion of the base 100. When the user presses the lever L, the engaging structure with the engaging portion 410 is released, and the cover 400 is rotated to the state shown in Fig.

5, the push member 500 pushes the electronic component FPCB toward the connection pin 101 and pushes the interference member 300 out of the path PA, do.

As shown in Figs. 2, 4 and 5, the push member 500 forms the pushing surface 501 and the inclined surface 502.

The pressing surface 501 is a surface that presses down the upper surface of the FPCB that is seated on the seating surface 201 by the rotational force of the cover 400 (in the process of the cover 400 being rotated close to the upper surface of the base 100) . The inclined surface 502 is a surface that presses down the sloping surface 303 of the interference member 300 by the rotational force of the cover 400 (in the process of the cover 400 being rotated close to the upper surface of the base 100).

The contact surfaces between the push member 500 and the interference member 300, that is, the slope surface 502 and the slope surface 303 form a slope with respect to the moving direction of the push member 500 and the interference member 300, respectively. 10, the sloped surface 303 has an angle of about 60 degrees with respect to the movement direction of the interference member 300, and the sloped surface 502 has an inclined angle of about 60 degrees with respect to the moving direction of the push member 500, Lt; RTI ID = 0.0 > 30. ≪ / RTI >

10 and 11, the push member 500 moves the electronic component FPCB to the connection pin (not shown) through the pressing surface 501 in the process of the cover 400 being rotated close to the upper surface of the base 100 101 while pushing the interference member 300 out of the path PA through the inclined surface 502. [

Fig. 10 shows a state in which the pressing surface 501 and the upper surface of the FPCB first make contact, and Fig. 11 shows a state in which the cover 400 is completely closed. In the process of closing the cover 400, the seating member 200 is lowered by the force of the push member 500 pressing down the upper surface of the FPCB (the first elastic member S1 is compressed). In the state shown in Fig. 11, the connector C is brought into contact with the connection pin 101, and a test of the electronic component FPCB is performed.

2 and 6, the blocking member 600 includes a cover (not shown) for blocking the movement of the interference member 300 pushed outside the path PA so as to be close to or away from the interference member 300 400, respectively. The interference member 300 is formed with a locking hole 304 into which the blocking member 600 is inserted.

As shown in FIG. 6, a third elastic member S3 is interposed between the blocking member 600 and the cover 400. As shown in FIG. The blocking member 600 is pressed toward the interference member 300 by the third elastic member S3, that is, downward.

A stepped portion 610 is formed at the edge of the blocking member 600. The stepped portion 610 is brought into close contact with the head of the bolt fastened to the cover 400 by the force of the third elastic member S3 in a state in which the cover 400 is open. Reference numeral 620 denotes a pin for guiding the up and down movement of the blocking member 600.

As shown in Fig. 10, the interference member 300 is pushed out of the path PA by the push member 500 when the cover 400 is closed. The second elastic member S2 is compressed as the interference member 300 is pushed out of the path PA. As shown in FIG. 11, when the cover 400 is completely closed, the latching hole 304 is positioned at a position where the blocking member 600 can be inserted.

The third elastic member S3 is compressed in the process of closing the cover 400 (until the blocking member 600 is inserted into the locking hole 304), as shown in Fig. 11, when the cover 400 is completely closed, the third elastic member S3 is resiliently restored, and the blocking member 600 is inserted deeply into the locking hole 304. As shown in FIG.

The blocking member 600 is inserted into the latching hole 304 so as to invade the moving section of the interference member 300. Therefore, the blocking member 600 prevents the movement of the interference member 300 due to elastic recovery of the second elastic member S2.

The length (or angle) at which the blocking member 600 has entered the moving section has an absolute value larger than the moving length (or the rotating angle) of the cover 400 due to the deformation amount of the third elastic member S3. 12, when the cover 400 is opened, the blocking member 600 moves (or rotates) the cover 400 by the length (or angle) of the blocking member 600 that is involved in the moving section, And then exit from the hole 304.

12, when the cover 400 is opened after the completion of the FPCB test, the blocking member 600 is pushed downward (after the seat member 200 is maximally raised by elastic recovery of the first elastic member S1) Even if the contact surface 501 of the member 500 and the upper surface of the FPCB are released, the state of being partially inserted into the engagement hole 304 is maintained. Therefore, the interference member 300 keeps the state away from the path PA even when it is pressed toward the path PA by the elastic recovery force of the second elastic member S2.

12, when the contact surface 501 of the push member 500 is released from contact with the upper surface of the FPCB when the cover 400 is opened, the electronic component FPCB is moved by the pusher 210 to the path PA So as to rise from the seating surface 201. The electronic component FPCB rises higher than the lower end of the sloped surface 303 by the pusher 210 and becomes free from the interference of the interference member 300 (prevention of the flow of the electronic component FPCB).

Therefore, the electronic component FPCB can be removed from the test socket 10 even if the cover 400 is further opened and the blocking member 600 comes out of the latching hole 304 and the interference member 300 again invades the path PA. ). ≪ / RTI >

According to the present invention, when the cover is closed, the push member pushes the electronic component toward the connection pin and forms the operating structure that pushes the interference member out of the path, so that even if the operator does not pay special attention, the FPCB is easily seated in a stable state, It is possible to provide a test socket in which breakage is prevented.

Further, when the cover is opened, the blocking member prevents the movement of the interference member pushed out of the path, and the pusher formed on the seating member forms an operating structure for pushing the electronic component in a direction opposite to the path on which the electronic component is placed. It is possible to provide a test socket which is made to be easy to carry out.

In addition, it is possible to provide a test socket in which the seating member is exposed while the cover is open, so that the FPCB can be seated with the view of the operator secured.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It is obvious to those who have. Accordingly, it should be understood that such modifications or alterations should not be understood individually from the technical spirit and viewpoint of the present invention, and that modified embodiments fall within the scope of the claims of the present invention.
