About.

In recent years, automobiles are changing rapidly from simple means of transportation to comprehensive living spaces that combine state-of-the-art electronic technology and IT technology, so the central nervous system of humans exchanges necessary power and data between the electronic systems of high-tech vehicles. The development of the wiring harness that performs the same role is also progressing.

Here, the wiring harness is a total assembly of wiring that serves as an electrical path for each electric system to perform its role by transmitting electrical signals and currents generated in each part of the vehicle to each other. It is an intermediate medium that transmits electrical energy generated from a generator or battery to each electronic device by electrically interconnecting a number of electrical devices and delivers various information generated from various switches and sensors to the corresponding parts.

Since such a wiring harness is exposed to vibrations due to sudden start, sudden braking, sudden curves and engines of a vehicle, and eventually disconnected due to repeated bending and deformation, it is important to accurately predict the durability life of the wiring harness.

For this, in the prior art, design, pilot production, and durability tests were repeatedly performed to predict the bending life of the wiring harness. That is, the electric wires distributed along the wiring path planned in the durability test are placed on a vibration base plate, and the vibration base plate is vibrated at a predetermined frequency and amplitude by a vibrator, and the electric wire bending life is predicted when it is vibrated by a specific frequency.

However, the development period of automobiles is shortened, and the bending life prediction requires higher accuracy. Therefore, the bending life prediction method, in which the durability test is repeated in such an environment, cannot be sufficiently shortened to satisfy the development period and does not sufficiently satisfy the demand for improvement in prediction accuracy.

As a conventional technology for testing the durability of the wiring harness as described above, Patent No. 10-1278192 "Durability test apparatus for a wire harness for wiring in a vehicle engine room" (hereinafter referred to as'Prior Art 1'), registered patent 10-1188402 "Harness Durability Test Device" (hereinafter referred to as "Prior Technology 2"), Registration Patent No. 10-1264855 "Durability Life Measurement Device for Vehicle Wire Harness" (hereinafter referred to as "Prior Art 3". ).

However, the prior art 1 tests the durability of the wire due to vibration, and as mentioned above, it is somewhat difficult to reproduce a situation such as an automobile driving environment, and there is a limit to predicting the bending life.

The prior art 2 provides an apparatus for testing durability of a harness for applying a load corresponding to a centrifugal force to a harness in a non-rotating manner, comprising: a load applying unit for applying a load corresponding to a centrifugal force to a harness coupled to a rotor blade; A linear motion unit coupled to one surface of the torsion control plate to which the rotor blades are coupled to move the torsion control plate up and down; Although it is composed of a torsion control unit for twisting the rotor blade at a certain inclination angle and applies a load corresponding to the centrifugal force, it is somewhat unreasonable to accurately grasp the durability of the wire as it has no choice but to transmit a continuous load without repeatedly stretching or reducing the wire. There is.

The prior art 3 is hinge-connected to the frame and has the same shape as the hinge shaft for guiding the opening and closing of the trunk of the vehicle, and a hinge member for wiring alignment of the sub-wire harness branching from the main wire harness, and a hinge member that is hinge-connected to the frame to be front and rear by external force. The present invention relates to a technology including a cylinder member for testing the durability of the sub-wire harness with respect to the main wire harness by rotating the hinge member under actual vehicle conditions.

In addition, the rotating shaft bar (B15) is further provided with an elastic body (B16) so that the elastic force can be imparted to the rotational motion of the rotating bar (B13), but the elastic body (B16) passes through a certain dead point, the elastic force in the opposite direction. It is limited to the elastic body (B16) to have.

Further, the elastic body (B16) is not shown in the drawing, but is provided on the rotating shaft bar (B15), and supports the rotating bar (B13), more precisely, the inner surface of the sliding hole (B131), and elastic force to the rotating bar (B13). At the same time, it is preferable that the rotating bar B13 is provided so as not to affect the elastic force even if it slides.

Hereinafter, the operation will be described through [A] and [B] of Fig. 6A and [C] and [D] of Fig. 6B,

First, [A] shows the state before insertion of the seating block (B1), and when the seating block (B1) is inserted together with the drawing [B], the insertion protrusion (B12) and the rotation bar (B13) are It is introduced through (B212) so that the rotation bar (B13) is located inside one side of the rotation guide groove (B211).

At this time, the N pole of the second magnet (B32) is arranged adjacent to the N pole to the second magnet (B35) so that the rotary bar (B13) rotates the rotary shaft rod (B15) by a repulsive force between the two. And, when rotating by the repulsive force and crossing the dead point of the elastic body (B16), it is naturally perpendicular to the insertion protrusion (B12) in the same state as [C] by the elastic force. At this time, it rotates while pushing the second push bar (B37), and the second push bar (B37) is provided on the other side of the rotation induction groove (B211) and is formed to protrude above the inlet block, and the second push bar (B37) When the bar (B37) rises as shown in [C], it is made so that it is not in its original position without external force by a separate locking protrusion. (It is obvious that the second push groove (B23) is provided on the other side of the inlet block.)

When the same state as [C] is reached again, the S pole of the first magnet B31 and the N pole of the first magnet B34 become close, and the rotating bar B13 moves to the left by their attractive force. ], and as the state is maintained, the seating block B1 and the inlet block B2 can be firmly fixed.

Conversely, in order to separate the seating block (B1), the first push bar (B36) is first pressed. When the first push bar (B36) is pressed, the first magnet (B31) and the second magnet (B32) rotate. The N poles of the first magnet B34 and the first magnet B31 are arranged adjacent to each other, and the rotation bar B13 slides to the right by repulsive force. At this time, when the auxiliary push bar is pressed, the rotation bar B13 is The end is lowered, the dead point of the elastic body B16 passes, and the second magnet B32 is in a state where the first push bar B36 is pressed by an attractive force between the S pole and the second magnet B35. ) The rotating bar (B13) is in the original position as shown in [B], and when the seating block (B1) is separated upward in the original position, the seating block (B1) can be naturally separated, so that it can be easily combined and separated. At the same time, it has a feature that can be firmly and stably fixed when combined.

In addition, in describing the present invention above, a wiring harness durability test apparatus having a specific shape, structure, and configuration has been mainly described with reference to the accompanying drawings, but the present invention can be variously modified, changed, and substituted by those skilled in the art. Modifications, changes and substitutions should be construed as falling within the scope of the present invention.
