Block diagram.

In FIG. 3, part (a) is a diagram showing a difference in length between the protruding part 210 and the main body part 220 of the present invention, and part (b) is a front view of the protruding part 210 of the present invention.

FIG. 4 is a diagram showing a circuit board block 300 of the present invention.

As shown in part (c) of FIG. 2, in the sliding type circuit board fixing device according to the present invention, in order to replace a circuit board, the coupling is simply released by sliding the bonded circuit board block 300. If a new circuit board block is slid, 300 to combine the intermediate block 200 with the circuit board block 300, the circuit board can be replaced, and thus the convenience when replacing the circuit board can be increased.

The sliding circuit board fixing device of the present invention includes a bottom plate 100, an intermediate block 200, and a circuit board block 300.

The bottom plate 100 has a predetermined shape. As an example, the bottom plate 100 may have a rectangular shape. The bottom plate 100 functions as a substrate that fixes and connects the plurality of intermediate blocks 200, the printed circuit board 400, and the circuit board block 300 connected to them.

In this specification, for convenience of description, the front direction of the middle block 200 is referred to as one side, and the rear direction is referred to as the other side.

A plurality of intermediate blocks 200 are disposed on the bottom plate 100. The intermediate block 200 can be arranged on the bottom plate 100 at equal intervals. A circuit board block 300 may be provided in each intermediate block 200.

The intermediate block 200 is formed of a main body portion 220 and a protruding portion 210.

The main body portion 220 of the intermediate block 200 is a portion fixed to the bottom plate 100 and has a hexahedron shape. The protruding portion 210 extends from one side of the main body portion 220. A connection groove is formed on the other side of the main body portion 220, and an installation groove 211 is formed in the protruding portion 210.

When the intermediate block 200 is fixed to the bottom plate 100, one side of the middle block 200 is spaced apart from the bottom plate 100. For this reason, the length 1 on one side of the intermediate block 200 is shorter than the length L on the other side. In this way, the space between the intermediate block 200 and the bottom plate 100 becomes a sliding space of the circuit board block 300.

The connection groove of the main body portion 220 of the intermediate block 200 is connected to the printed circuit board 400. Among them, if the printed circuit board 400 is partially connected to the intermediate block 200 to electrically transmit and receive signals, it is not a big deal. Therefore, as long as the printed circuit board 400 is partially connected to the intermediate block 200, the connection groove is sufficient. The length is not a problem.

An installation groove 211 is formed in the protruding portion 210 of the intermediate block 200. When the circuit board block 300 slides and is fixed, the setting groove 211 guides and moves the circuit board block 300.

The lower part of the installation groove 211 is opened, and the length continuously increases from the open lower part to the upper part. That is, the cross section of the installation groove 211 may be triangular.

The reason why the length of the upper part and the lower part of the installation groove 211 is different is that it functions as a guide that is one of the functions of the installation groove 211, and at the same time is used to stably fix the circuit board block 300 guided and moved by the installation groove 211 .

Since the circuit board block 300 is guided and moved to the setting groove 211, the shape of the circuit board block 300 should be a shape corresponding to the setting groove 211, and the details thereof will be described later.

Looking further closely at the protruding portion 210 of the intermediate block 200, a flange portion 212 is formed in two directions below the protruding portion 210, and a plurality of fixing holes 213 are formed in the flange portion 212.

The flange portion 212 provides a position space for setting a variable bolt 500 that presses the circuit board block 300 and fixes the circuit board block 300. The flange portions 212 are formed on both sides of the protruding portion 210, and the fixing holes 213 are respectively formed on the flange portions 212 on the two sides to press the circuit board 300 from both sides by the variable bolt 500, so that the circuit board 300 When it is located at the lower part of the intermediate block 200, it can be stably fixed.

On the bottom plate 100, the circuit board block 300 is guided to the space between the bottom plate 100 and the intermediate block 200 by the setting groove 211, and is fixed by sliding.

The circuit board block 300 includes a contact portion 310 and a sliding portion 320.

The contact portion 310 is connected to the upper side of the sliding portion 320 and has a shape corresponding to the setting groove 211. That is, the length of the contact portion 310 increases continuously from the lower portion to the upper portion. That is, the cross section of the contact portion 310 is also triangular.

The sliding portion 320 is a portion that is in contact with the bottom plate 100 and slides. The sliding portion 320 has a hexahedron shape.

The height of the sliding portion 320 is not higher than the separation distance between the intermediate block 200 and the bottom plate 100. Therefore, the contact portion 310 is guided by the setting groove 211, and the sliding portion 320 can slide between the spaced distance between the intermediate block 200 and the bottom plate 100.

A circuit board such as a printed circuit board 400 or a flexible circuit board is mounted on the circuit board block 300.

This also applies to the intermediate block 200. That is, an intermediate circuit board capable of transmitting and receiving signals with the printed circuit board 400 is mounted on the intermediate block 200, and the intermediate circuit board transmits signals of the printed circuit board 400 to the circuit board block 300. The circuit board mounted on the circuit board block 300 is electrically connected to the intermediate circuit board mounted on the intermediate block 200 again. The above-mentioned electrical connection has portions that electrically connect the inner side surface of the installation groove 211 and the outer side surface of the contact portion 310 respectively, so that as long as the circuit board block 300 is simply inserted into the intermediate block 200, the electrical signals can be transmitted to the circuit board block 300 .

On one side of the circuit board block 300, there is a portion (contact portion) where signals can be transmitted again by electricity. As an example, the normal operation of the display substrate can be tested when it is in contact with the contact portion of the display substrate.

When the circuit board block 300 needs to be replaced in order to test other display basics, the existing circuit board block 300 inserted and fixed in the intermediate block 200 can be taken out, and a new circuit board block 300 can be inserted into the intermediate block 200. Simply replace the circuit board.

In FIG. 5, part (a) is a diagram showing the variable bolt 500 inserted into the fixing hole 213, and part (b) is an interval diagram of the variable bolt 500.

The variable bolt 500 is provided in the fixing hole 213. The variable bolt 500 includes a body 510, an elastic mechanism 520, and a pressure body 530. The body 510 is fixed in the fixing hole 213 and does not move. A spiral thread and a groove are formed in the body 510 of the variable bolt 500, and a spiral thread and a groove are formed in the fixing hole 213 so that the thread is inserted and fixed by rotation.

The lower part of the body 510 is open. An elastic mechanism 520 is provided inside the body 510, and the open lower portion is provided with a pressure body 530 connected to the elastic mechanism 520. The pressurizing body 530 is disposed at a distance between the intermediate block 200 and the bottom plate 100.

The circuit board block 300 is fixed to the intermediate block 200 by sliding to the intermediate block 200 by a variable bolt 500.

When the circuit board block 300 is guided and slid by the insertion groove, the pressurizing body 530 of the variable bolt 500 moves to the upper part by a movement contacting the sliding portion 320 of the circuit board block 300. When the sliding portion 320 moves a set distance, the pressing body 530 of the variable bolt 500 presses the upper surface of the sliding portion 320 by the elastic force of the elastic mechanism 520.

The pressing body 530 has a circular shape, and an inclined portion may be formed on a peripheral surface of the sliding portion 320 of the road plate 300. Therefore, when the sliding portion 320 slides to the intermediate block 200, the pressing body 530 naturally moves to the upper portion due to the inclined portion of the peripheral surface of the sliding portion 320, and then moves to the lower portion by the elastic mechanism 520, so that the circuit board block can be moved. 300 is pressurized.

In FIG. 6, part (a) shows a guide protrusion 610, a stop protrusion 620, and a guide groove 630 formed on the circuit board block 300 in the sliding type circuit board fixing device according to another embodiment of the present invention. In the figure, part (b) is a diagram showing a state where the intermediate block 200 and the circuit board block 300 are not combined in a sliding circuit board fixing device according to another embodiment of the present invention, and part (c) is a diagram showing the state of the present invention. In a sliding circuit board fixing device according to another embodiment, a diagram of a state where the intermediate block 200 and the circuit board block 300 are combined.

According to the sliding circuit board fixing device according to another embodiment, a guide protrusion 610 and a stop protrusion 620 may be formed on the bottom plate 100, and a guide groove 630 for inserting the guide protrusion 610 may be formed on the circuit board block 300.

The sliding circuit board fixing device according to another embodiment can be more accurately guided and moved by the above-mentioned guide groove 630 and the guide protrusion 610.

That is, the guide groove 630 of the circuit board block 300 is slid to the intermediate block in a state in which the guide protrusion 610 is coupled. After that, when the circuit board block 300 is moved to the set position, the slide protrusion 620 is prevented from further sliding. That is, the circuit board block 300 is allowed to slide to a set degree.

Although the present invention has been shown and described with reference to specific embodiments, it is obvious to those having ordinary knowledge in the technical field to which the present application belongs. The invention makes various improvements and changes.
