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

The jumper pin 110 serves to electrically connect (energize) the first printed circuit board 10 and the second printed circuit board 20. Thus, the jumper pin 110 is made of a material having electric conductivity.

In particular, the jumper pin 110 includes a body 112 having a predetermined volume for securing an amount of current. For convenience, the body 112 is assumed to have a substantially rectangular parallelepiped shape.

4, the jumper pin 110 is formed by extending the first elastic deforming member 114 to one side (lower side) of the body 112, and extending to the other side (upper side) (116).

The first elastic deformable member 114 forms a first through-hole 115 which is rectangular in the axial direction of the jumper pin 110. Therefore, the first elastic deformable member 114 can be elastically deformed such as being pinched or stretched in the direction of the opening (a) of the first passage hole 115.

Likewise, the second elastic deformable member 116 forms the second through-hole 117 which is rectangular in the axial direction of the jumper pin 110. Thus, the second elastic deformable member 116 can be elastically deformed such as being pinched or stretched in the direction of the opening (a) of the second passage hole 117.

The first elastic deformable member 114 is inserted into the first through hole 12 formed in the first printed circuit board 10 while the second elastic deformable member 116 is inserted into the second printed circuit board 20 The second through hole 22 penetrates through the through hole 22.

At this time, since the first elastic deformation member 114 slips in the direction of the opening (a) of the first through hole 115 when the first elastic deformation member 114 is forcedly inserted into the corresponding first through hole 12, (12). Similarly, when the second elastic deformation member 116 is forcedly inserted into the corresponding second through-hole 22, the second elastic deformation member 116 slips in the direction of the opening (a) of the second through-hole 117, (22).

Thereby, it is not necessary that the first elastic deformable member 114 is inserted into the first printed circuit board 10 and then soldered, and when the second elastic deformable member 116 is inserted into the second printed circuit board 20 It does not need to be soldered.

Particularly, in order to protect the circuit pattern (not shown) from the heat generated during soldering, the portions where the jumper pins 110 are inserted into the first printed circuit board 10 and the second printed circuit board 20, Pattern and a plane-set distance.

As a result, the planarity of the first printed circuit board 10 and the second printed circuit board 20 increases. However, since the first elastic deformable member 114 and the second elastic deformable member 116 are fixedly inserted into the corresponding first through hole 12 and the second through hole 22, The planarity of the first printed circuit board 10 and the second printed circuit board 20 can be reduced.

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

The support block 120 is configured to house the jumper pins 110, particularly the body 112, to protect the jumper pins 110, to support the first printed circuit board 10 on the lower surface thereof, The second printed circuit board 20 is held in contact with the second printed circuit board 20.

At this time, the support block 120 is made of an insulating material to prevent energization of the jumper pins 110 housed inside.

In detail, the support block 120 forms an opening hole portion 122 which forms an inner space open to both sides along the axial direction. Then, the body 112 of the jumper pin 110 is mounted on the opening hole portion 122 and fixed. The first resiliently deformable member 114 of the jumper pin 110 is disposed so as to protrude in one direction (lower direction) of the support block 120 and the second resiliently deformable member 116 of the jumper pin 110 (Upper) direction of the support block 120. As shown in FIG.

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

Thus, the jumping device 100 includes the supporter 130.

The supporter 130 protrudes to the inside of the opening hole portion 122 and serves to support the body 112 of the jumper pin 110 mounted on the opening hole portion 122. As a result, the body 112 can be stably mounted inside the supporter 130.

For example, the supporter 130 is supposed to support one side (one end) of the body 112 in contact therewith. At this time, since the connecting portion between the body 112 and the first elastic deformable member 114 may be weak, a part of the first elastic deformable member 114 connected to the body 112 by the support block 120, The position of the supporter 130 relative to the inside of the opening hole portion 122 can be set.

Of course, the supporter 130 can be modified into various shapes.

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

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

This is because the first resilient deformable member 114 abuts against the first through hole 12 of the first printed circuit board 10 while the jumper pin 110 is mounted on the opening hole portion 122 of the support block 120. [ The body 112 is supported on the other side of the support block 120 to prevent the body 112 from being pushed in the other direction.

In detail, when the first printed circuit board 10 is placed on the floor or a work table (not shown), the support block 120 housing the jumping apparatus 100 is placed on the first printed circuit board 10 do. At this time, the first resiliently deformable member 114 is aligned with the corresponding first through hole 12.

Thereafter, the operator touches the other side of the support block 120 and the other side of the body 112 at the same time as the jig 50. The first elastic deformable member 114 is pushed into the corresponding first through hole 12 so that the body 112 is prevented from being pushed in the axial direction while being received in the opening hole portion 122 of the support block 120, The initial state is maintained.

At this time, the jig 50 can be deformed into various shapes.

Particularly, the area of the body 112 contacting the jig 50 can be increased. 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 the other side is formed to be flush with the other side of the body 112.

Further, the diameter of the opening hole portion 122 can be adjusted, for example, the support block 120 can be formed so that the other side (the inside upper side) of the opening hole portion 122 is extended to receive the shoulder member 113.

The support block 120 is supported by the first elastic deformable member 114 and the second elastic deformable member 116 that are received in the plurality of opening hole portions 122 along the axial direction A support protrusion 124 may be provided between the adjacent aperture openings 122. [

For the sake of convenience, the support protrusions 124 are disposed between the openings 122 adjacent to 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 are not limited.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. I will understand. Accordingly, the true scope of the present invention should be determined by the following claims.
