The present invention relates to a fixing structure of a multi-layer printed circuit board, and more particularly, to a fixing structure of a multi-layer printed circuit board, which has a simple structure and a high fixing force using a printed circuit board fixing portion having slots.
A printed circuit board refers to a thin plate to which electrical components such as integrated circuits, resistors and switches are soldered, and is used in various fields as well as the computer field.
A fixing structure for fixing printed circuit boards is shown in
The fixing structure of the multi-layer printed circuit board, shown in
When a plurality of printed circuit boards are connected using bolts each having a protrusion portion as shown in
Further, there is a problem in that a component such as the bolt does not appropriately maintain a fixing force because the strength of the component is weak due to the continuous exhaustion such as vibration.
Meanwhile, the number of printed circuit boards used in a battery control device used in a electric automobile or hybrid automobile is large, and a large number of printed circuit board are mounted in a narrow space as automobiles tend to be miniaturized. Since it takes a long period of time to fix printed circuit boards with a low fixing force using the conventional method, there is a problem in that productivity is considerably lowered.
Accordingly, the present invention is conceived to solve the aforementioned problems. An object of the present invention is to provide a fixing structure of a multi-layer printed circuit board, wherein a plurality of printed circuit boards are simply fixed by a one-time connection using a printed circuit board fixing portion having slots, so that efficiency of assembling and disassembling operations can be improved, and it is possible to prevent deformation and damage from occurring by improving a fixing force of the printed circuit boards.
According to an aspect of the present invention for achieving the object, there is provided a fixing structure of a multi-layer printed circuit board, which includes: a plurality of printed circuit boards 10 each having through-holes 11 at corners thereof; a printed circuit board fixing portion 20 having a plurality of slots 21 into the corners of the printed circuit boards 10 are inserted to be fixed, and a fixing groove 22 formed long in a lateral direction so that the through holes 11 of the printed circuit boards 10 are exposed; and a connection means 30 guided along the fixing groove 22 and passing through the through-holes 11 of the respective printed circuit boards 10.
Further, a pair of the printed circuit board fixing portions 20 may be spaced apart from each other at a predetermined distance to fix both ends of the printed circuit boards 10.
Further, the printed circuit board fixing portion 20 may have a seating portion 23 formed to a predetermined depth at an inside thereof so that the printed circuit boards 10 are more stably fixed.
Further, the printed circuit board fixing portion 20 may have a plurality of ventilation portions 24 formed at the seating portion 23.
Accordingly, the fixing structure of the multi-layer printed circuit board according to the present invention has an advantage in that a plurality of printed circuit boards can be simply fixed by a one-time connection using a printed circuit board fixing portion having slots, and the number of assembly components can be remarkably reduced through a simple configuration, thereby enhancing efficiency of assembling and disassembling operations of the multi-layer printed circuit board.
Further, the fixing structure of the multi-layer printed circuit board according to the present invention has an advantage in that it is possible to prevent deformation and damage from occurring by improving a fixing force.
The above and other objects, features and advantages of the present invention will become apparent from the following description of preferred embodiments given in conjunction with the accompanying drawings, in which:
Hereinafter, a fixing structure of a multi-layer printed circuit board according to the present invention will be described in detail with reference to accompanying drawings.
such as a fuel cell, a plurality of printed circuit boards are frequently stacked to be used. Accordingly, a means for fixing a multi-layer printed circuit board is required to be suitable for an environment such as an automobile, in which vibrations are continuously generated.
In the present invention, the multi-layer printed circuit board is simply and firmly fixed using the printed circuit board fixing portion 20, which will be described in detail below.
The printed circuit board 10 has a through-hole 11 for connection, formed at each corner thereof.
The printed circuit board fixing portion 20 has a plurality of slots 21 into which the corners of the printed circuit boards 10 are inserted to be fixed, and a fixing groove 22 is formed long in a lateral direction so that the through holes 11 are exposed.
The width of the slot 21 is adjusted depending on the thickness of the printed circuit board 10, and the corner of the printed circuit board 10 is inserted into the slot 21 as shown in
The connection means 30 is guided along the fixing groove 22 and fixed by passing through the through-holes 11 of the respective printed circuit board 10. Although it has been shown in
A connector 40 is a means for electrical connection between the printed circuit boards 10 and may be variously formed.
As described above, the present invention has an advantage in that the number of assembly components is remarkably decreased, thereby enhancing efficiency of assembling and disassembling operations of the multi-layer printed circuit board.
As shown in
Preferably, the printed circuit board fixing portion 20 has a seating portion 23 formed to a predetermined depth at an inside thereof into which the printed circuit boards 10 are inserted so that the printed circuit boards 10 are more stably fixed.
The corners of the printed circuit boards 10 are inserted into the slots 21 of the printed circuit board fixing portion 20, and the fixing force of the printed circuit boards 10 can be more enhanced due to the formation of the seating portion 23. One side of the printed circuit board 10 is supported by the seating portion 23 of the printed circuit board fixing portion 20, and the insertion length of the printed circuit board is adjusted.
The printed circuit board fixing portion 20 has a plurality of ventilation portions 24 formed at the seating portion 23.
Preferably, a large number of ventilation portions 24 are formed in the printed circuit board fixing portion 20 to prevent lowering of ventilation characteristics generated by fixing both ends of the printed circuit boards 10 when a pair of the printed circuit board fixing portions 20 are spaced apart from each other. Accordingly, heat generated in operation of the multi-layer printed circuit board can be easily discharged.
