4 is an exploded cross-sectional view of the stripper 400 according to a preferred embodiment of the present invention.

The remover 400 is a release function for releasing a coupling state of the coupling body 220 detachably coupled to the insert body 210 and the insert body 210 in which the coupling body is released from the insert body 210 and the insert body 210. It is provided to sequentially realize the stripping function to remove from), as shown in Figure 4, it comprises a release plate 410, stripping plate 420 and the coupling structure.

The release plate 410 has a shape of a generally rectangular plate as referred to in the bottom view of FIG. 5, and four releases forming a pair capable of releasing the engagement of the elastic piece 221 provided in the assembly 220. The pin 411 is provided in multiple rows. And the release plate 410 is a position where the release pin 411 can be inserted into the locking groove 212, more specifically, the position of the release pin 411 to a position to release the locking of the elastic piece 221 It further has positioning pins 412 that can be inserted into the positioning grooves 213 (see FIGS. 2 and 3) formed in the insert body 210 so that the shape can be determined. For reference, the release plate 410 of FIG. 4 is represented by a side cross-sectional view taken along the line I-I of FIG.

In addition, the release plate 410 is formed with a plurality of pairs of through holes 413 through which a pair of stripping pins 421 provided in the stripping plate 420 to be described later are formed in a plurality of rows. There is a pair of coupling holes 414 formed stepped to integrally couple a pair of coupling rods 432 to be described later is formed.

As shown in the bottom view of FIG. 6, the stripping plate 420 is paired with the release plate 410, and the engagement state of the stripping plate 420 is erased by the release pin 411 to release the engagement state. A pair of stripping pins 421 are provided in a plurality of rows to remove the coupling body 220 from the insert body 210 by pushing the coupling body 220 downward. And the stripping plate 420 is formed with a pair of engaging holes 422 that can take the other side of the coupling bar 432, one side is integrally coupled to the release plate 410, furthermore stripping pin ( 411 is provided on the opposite side is provided with a handle 423 for improving the workability of the operator. For reference, the stripping plate 420 of FIG. 4 is a side cross-sectional view taken along the line II-II of FIG. 6 and viewed from the B direction.

The coupling structure includes a coil spring 431 and a coupling rod 432 provided as an elastic member.

The coil spring 431 is provided to mutually elastically support the release plate 410 and the stripping plate 420. After the external pressing force is applied, the coil spring 431 narrows the interval between the release plate 410 and the stripping plate 420. When the pressing force is released serves to open the gap between the release plate 410 and the stripping plate 420.

Coupling rod 432 is provided inside the coil spring 431 to prevent the bending of the coil spring 431, one side (lower side) is bolted to the release plate 410 at the position of the coupling hole 414 ( It is integrally coupled by V) and the other side (upper side) is extended so that the radius thereof is held in the engaging hole 422 formed in the stripping plate 420. Therefore, the stripping plate 420 may be moved relative to the release plate 410 by an external force or an elastic force of the coil spring 431, and the other side of which the radius is extended is caught by the catching hole 422 so that the coil spring ( The stripping plate 420 is prevented from being completely separated from the release plate 410 by the elastic force of the 431.

On the other hand, when seeing the coupling structure from the other point of view, the engaging hole 422 formed in the coupling rod 432 and the stripping plate 420 is the stripping plate 420 when the stripping plate 420 moves relative to the release plate 410 It also serves to guide the movement of 420. Therefore, the coupling rod 432 is a guide rod, the engaging hole 422 can be named as a guide hole.

Subsequently, the operation of the stripper 400 having the above configuration will be described with reference to FIG. 7.

First, when the operator wants to remove the assembly 220 from the insert body 210, the handle 423 of the remover 400, as shown in Figure 7, the insert body in contrast to the insert body 210 The remover 400 is positioned to be arranged in the order of the 210, the release plate 410, and the release plate 420.

Then, when the positioning pin 412 is inserted into the positioning groove 213 formed in the insert body 210, as shown in Figure 8, the release pin 411 at the lower end of the locking groove 212 It is naturally located in a position to release the locking state of the hanging elastic piece 221. Of course, the stripping pin 421 is also located in a proper position to push the assembly 220 is natural.

When the operator applies the pressing force F to the stripper 400 in the insert body 210 side in the state as shown in FIG. 8, as shown in FIG. 9, the stripper 400 is completely inserted into the insert body 210 side. While in close contact, the release pin 411 releases the engagement of the elastic piece 221.

In the state as shown in FIG. 9, when the operator continuously applies the pressing force F toward the insert body 210 to the stripper 400, the release plate 410 maintains a relatively stationary state with respect to the insert body 210. On the other hand, the removal plate 420 is moved to the insert body 210 side. At this time, the stripping plate 420 is moved while being guided in a balanced manner by the coupling bar 432, the stripping pin 421 with the movement of the stripping plate 420 is pushed down the assembly 220. Therefore, when the stripping plate 420 moves to the insert body 210 side as much as possible, as shown in FIG. 10, the coupling body 220 is completely pushed downward by the stripping pin 421, and ultimately, the insert body ( The combination 220 can be completely removed from the 210.

On the other hand, the operating state diagram of Figures 7 to 10 shows an example of removing the combinations 220 from a plurality of inserts at a time, the insert 200 shown in Figures 7 to 10 is a matrix in the frame of the test tray The frame is omitted and shown in a state in which the mounting arrangement. That is, the insert 220 may be removed from the insert body 210 by using the extractor 400 while the inserts 200 are arranged in a matrix in the frame.

According to the operation of the stripper 400, the release function by the release plate 410 and the stripping function by the stripping plate 420 is sequentially realized by the external continuous pressing force. To this end, the strength of the coil spring 431 of the coupling structure should maintain an appropriate strength. The strength of the coil spring 431 should be greater than the force for releasing the plurality of release pins 411 of the elastic pieces 221. If the strength of the plurality of release pins 411 is less than the force for releasing the engagement of the elastic pieces 221, the stripping pins 421 are in contact with the assembly 220 before the coupling state of the assembly 220 is released. do. And when the strength of the coil spring 431 is too large, it is difficult to use the stripper 400.

In addition, in the insert 200 illustrated in FIGS. 2 and 3, an elastic piece 221 having a rounded portion to maintain the state in which the coupling body 220 is coupled to the insert body 210 is used. When such an elastic piece 221 is used, it may be possible to remove the assembly 220 from the insert body 210 only with the stripping plate 420 of FIG. 4 having the stripping pin 421. That is, when the insert 200 shown in FIGS. 2 and 3 is applied, it is possible to configure the stripper using only the stripping plate 420. In this case, it is more preferable to further configure the positioning pins such that the stripping pins are positioned at an appropriate position to push the assembly.

And, according to the stripper 400 shown in Figure 4 the release function is implemented by the release plate 410, the stripping function is removed by the stripping plate 420. However, in the case of removing the assembly from the insert using only the stripping plate, only the stripping plate implements both the release function and the stripping function.
