Jumping device for automotive printed circuit boards {PRINTED CIRCUIT BOARDS JUMPING DEVICE}

The present invention relates to a jumping device for an automotive printed circuit board, and more particularly, each elastic deformation member is inserted into a support block while a jumper pin having extended elastic deformation members formed on both sides thereof is protected. The present invention relates to a jumping device for a printed circuit board for automobiles, which can easily use a press-fitting jig when press-through the through hole of the substrate, and prevents assembly of a jumper pin to the printed circuit board.

In vehicles, power and control of various electrical components are required. As such, a box such as a junction box, a joint box, a battery box, etc. is used to collectively perform power supply and control for various electrical components.

Such a box is composed of components such as fuses and relays and a circuit board integrated therein.

Recently, a separate block of a substrate that performs the function of a box or a separate box is often used.

Such a substrate block performs substantially the same function as one box. In addition, a plurality of printed circuit boards are used in the substrate block, and these printed circuit boards are generally disposed in parallel with each other.

In order to arrange the printed circuit boards in parallel with each other, it is necessary to electrically connect the printed circuit boards with wires or jumper pins. In addition, a structure for fixing each printed circuit board should be separately provided.

In particular, after the conventional printed circuit board is soldered and mounted on the electronic device, the facing printed circuit board is soldered and connected with jumper pins, so that the electronic device mounted on the printed circuit board generates thermal deformation during the soldering operation of the jumper pins. Or malfunction.

In order to prevent this, there has been proposed a technique for forming a needle-shaped elastic deformation member on both sides of the jumper pin, forcibly inserting it into a through hole of a corresponding printed circuit board to induce energization.

The above technical configuration is a background art for helping understanding of the present invention, and does not mean a conventional technology well known in the art.

As a prior art, Korean Patent Application Publication No. 10-2012-0059134 (published: 2012.06.08.) Has proposed a printed circuit board and a vehicle substrate block using the same.

In the case of the conventional jumper pin forming the needle-shaped elastic deformation member on both sides, there is a problem in that a poor assembly or energization failure occurs because the depth (height) of the printed circuit board is inserted into the plurality of elastic deformation members. In addition, as a jumper pin having an existing elastic deformation member is required to be press-fitted in various shapes such that the jumper pin is press-fitted into the through hole of the corresponding printed circuit board, assembly productivity is lowered.

Therefore, there is a need for improvement.

The present invention has been made in order to solve the above problems, while each of the elastic deformation member is inserted through the support block to protect the jumper pins that extend the elastic deformation member on both sides, the through-hole of the corresponding printed circuit board It is an object of the present invention to provide a jumper for a printed circuit board for automobiles that can easily use a press-fitting jig when press-fitting into a through hole and prevents assembly of a jumper pin on a printed circuit board.

In addition, the present invention provides an additional area of the printed circuit board to prevent the circuit pattern of the printed circuit board from being affected by soldering because an additional soldering process is unnecessary as the elastic deformation member is pressed into the through hole of the printed circuit board. It is an object of the present invention to provide a jumping device for a printed circuit board for automobiles, which is intended to reduce the size of the printed circuit board because the area is unnecessary.

The jumping device for a printed circuit board for automobiles according to the present invention includes: a first elastic deformation member press-fitted and electrically connected to a first printed circuit board, and a second elastic deformation member press-fit and electrically connected to a second printed circuit board Jumper pins having a; An insulating material support block through the opening hole for inserting the jumper pin to protrude the first elastic deformation member and the second elastic deformation member; And a supporter protruding inside the opening hole and supporting the jumper pin mounted to the opening hole.

The jumper pin includes a body connecting the first elastic deformation member and the second elastic deformation member, and the body is connected to the support block so that the other end is exposed to the other side of the support block when one side contacts the supporter. Can be mounted.

When the first elastic deformation member provided on one side of the body is inserted into the first printed circuit board, the other side of the body and the other side of the support block may be prevented from being pushed in contact with the jig.

The support block may form a plurality of opening holes along the axial direction, and may include support protrusions between adjacent opening holes for supporting lateral bending of the first elastic deformation member or the second elastic deformation member. have.

As described above, the jumping device for a printed circuit board for automobiles according to the present invention, unlike the prior art, each of the elastic deformation members while inserting and protecting a jumper pin formed by extending the elastic deformation members on both sides of the support block.

1 to 5, the jumping device 100 of an automotive printed circuit board according to an exemplary embodiment of the present invention includes a jumper pin 110 and a support block 120.

The jumper pin 110 electrically connects the first printed circuit board 10 and the second printed circuit board 20 to each other. Thus, the jumper pin 110 is made of a material having electrical conductivity.

In particular, the jumper pin 110 includes a body 112 having a constant volume to secure a current amount. For convenience, the body 112 has a substantially rectangular parallelepiped shape.

In addition, the jumper pin 110, as shown in FIG. 4, extends the first elastic deformation member 114 to one side (lower side) of the body 112, and the second elastic deformation member to the other side (upper side) of the batty. 116 is extended.

The first elastic deformation member 114 forms a first through hole 115 that is rectangular in the axial direction of the jumper pin 110. Thus, the first elastic deformation member 114 may be elastically deformed, for example, by being pinched or unrolled in the direction of the diameter (a) of the first passage hole 115.

Similarly, the second elastic deformation member 116 forms a second opening hole 117 that is rectangular in the axial direction of the jumper pin 110. Thus, the second elastic deformation member 116 may be elastically deformed, for example, by being pinched or unrolled in the direction of the diameter a of the second passage hole 117.

The first elastic deformation member 114 is forcibly inserted into the first through hole 12 through the first printed circuit board 10, and the second elastic deformation member 116 is inserted into the second printed circuit board 20. Is inserted into the second through hole 22 through.

At this time, since the first elastic deformation member 114 is retracted in the direction of the diameter (a) of the first through hole 115 when forcibly inserted into the corresponding first through hole 12, the first through hole is caused by an elastic restoring force. It maintains firmly the state inserted in (12). Similarly, since the second elastic deformation member 116 is retracted in the direction of the diameter (a) of the second through hole 117 when forcibly inserted into the corresponding second through hole 22, the second through hole is caused by the elastic restoring force. It maintains firmly the state inserted in 22.

Accordingly, the first elastic deformation member 114 does not need to be soldered after being inserted into the first printed circuit board 10, and the second elastic deformation member 116 is inserted into the second printed circuit board 20 after being inserted into the second printed circuit board 20. It does not need to be soldered.

In particular, in the past, the portion where the jumper pin 110 is inserted into the first printed circuit board 10 and the second printed circuit board 20 is used to protect the circuit pattern (not shown) from heat during soldering. It is arranged to be spaced apart by the set distance on the pattern and plane.

As a result, the planar area of the first printed circuit board 10 and the second printed circuit board 20 increases. However, as the first elastic deformation member 114 and the second elastic deformation member 116 are fixed after being inserted into the corresponding first through hole 12 and the second through hole 22, a separate soldering process is performed. Since it is unnecessary, the planar area of the first printed circuit board 10 and the second printed circuit board 20 can be reduced.

  Of course, the height (length) and the shape of the first elastic deformation member 114 and the second elastic deformation member 116 are not limited.

Meanwhile, the support block 120 protects the jumper pin 110 by accommodating the jumper pin 110, in particular, the body 112, and supports the first printed circuit board 10 in contact with the lower side. The second printed circuit board 20 is in contact with and supported.

At this time, the support block 120 is made of an insulating material to prevent the current flow between the jumper pins 110 accommodated inside.

In detail, the support block 120 forms an opening hole portion 122 which opens the space inside to both sides along the axial direction. In addition, the body 112 of the jumper pin 110 is mounted and fixed to the opening hole 122. Thus, the first elastic deformation member 114 of the jumper pin 110 is disposed to protrude in one direction (lower) direction of the support block 120, the second elastic deformation member 116 of the jumper pin 110 is The support block 120 is disposed to protrude in the other side (upper) direction.

In addition, the support block 120 should support the body 112 of the jumper pin 110 inserted from the lower side.

Thus, the jumping device 100 includes a supporter 130.

The supporter 130 protrudes inside the opening hole 122 to support the body 112 of the jumper pin 110 mounted on the opening hole 122. For this reason, the body 112 may be stably mounted inside the supporter 130.

As an example, the supporter 130 is in contact with and supports one side (one end) of the body 112. At this time, the connection portion between the body 112 and the first elastic deformation member 114 may be fragile, and the support block 120 has a part of the first elastic deformation member 114 connected to the body 112 therein. In order to position, the position of the supporter 130 with respect to the inside of the opening hole 122 may be set.

Of course, the supporter 130 may be modified in various shapes.

Therefore, the jumper pin 110 is assembled to the opening hole 122 through the other side of the support block 120.

At this time, the other side (the other end) of the body 112 is to be approximately the same height as the other side of the support block 120. Through this, the other end of the body 112 is exposed to the other side of the support block 120.

This is because the first elastic deformation member 114 has the first through hole 12 of the first printed circuit board 10 with the jumper pin 110 mounted on the opening hole 122 of the support block 120. In order to prevent the body 112 from being pushed in the other direction as the body 112 is supported at the other side of the support block 120.

In detail, in a state in which the first printed circuit board 10 is placed on the floor or a work table (not shown), the support block 120 containing the jumping device 100 is placed on the first printed circuit board 10. do. In this case, the first elastic deformation member 114 corresponds to the corresponding first through hole 12.

Afterwards, the worker contacts and presses the other side of the support block 120 and the other side of the body 112 simultaneously with the jig 50. Accordingly, the first elastic deformation member 114 is pressed into the corresponding first through hole 12, and the body 112 is accommodated in the opening hole 122 of the support block 120 while being prevented from being pushed in the axial direction. Maintain the initial state.

At this time, the jig 50 can be modified in various shapes.

In particular, the body 112 may increase the area where the other side is in contact with the jig 50. To this end, the body 112 extends the shoulder member 113 along the other side (upper side) circumferential surface. The shoulder member 113 is formed integrally with the body 112 and is formed so that the other side is flush with the other side of the body 112.

In addition, the support block 120 may be formed such that the other side (upper inner side) of the opening hole 122 may be expanded to accommodate the shoulder member 113, and the diameter of the opening hole 122 may be adjusted.

In addition, the support block 120 supports the lateral bending of at least one of the first elastic deformation member 114 and the second elastic deformation member 116 accommodated in the plurality of opening holes 122 along the axial direction. The support protrusions 124 may be provided between the adjacent opening holes 122.

For convenience, the support protrusion 124 may be disposed between the adjacent opening holes 122 on the other side of the support block 120. Accordingly, the support protrusion 124 supports the second printed circuit board 20 on the other side of the support block 120.

Of course, the number and size of the support blocks 120 is not limited.

Although the present invention has been described with reference to the embodiments shown in the drawings, this is merely exemplary, and those skilled in the art to which the art belongs can make various modifications and other equivalent embodiments therefrom. I will understand. Therefore, the true technical protection scope of the present invention will be defined by the claims below.
