1 to 6, the wire harness fixing jig according to an embodiment of the present invention is arranged in pairs in the same shape, and after pressing and fixing each side of the wire harness, respectively, which one is rotated with respect to the other by an external operation. While bending the wire harness test equipment, the base frame 10, the fixed frame 20, the support protrusion 30, the moving frame 40, the operation unit 50 and the pressing member 60.

For convenience, only one wire harness fixing jig is shown.

Base frame 10 serves to support the lower side of the wire harness fixing jig according to an embodiment of the present invention. In particular, the base frame 10 is preferably formed in a flat plate shape in order to stably support the fixed frame 20. The base frame 10 may be formed of various materials.

In addition, the fixed frame 20 is formed above the base frame 10. In particular, the fixed frame 20 is detachably coupled to the base frame 10 by the fastening member (5). Here, the fastening member 5 is preferably made of bolts.

In addition, the fixed frame 20 is provided with a slide channel 22 therein along the longitudinal direction, that is, the axial direction. That is, the fixed frame 20 is formed in communication with both sides. Of course, the slide channel 22 may be a hole shape communicated to both sides of the fixed frame 20, it is preferably formed to be opened to the lower side. This is to facilitate the assembly of the moving frame 40.

And, the fixed frame 20 is formed to connect the receiving port 24 up and down. The receiver 24 is connected to the slide channel 22. Receiving port 24 is a hole (hole) formed in the upper and lower communication with the fixing frame 20, it may be formed in a variety of shapes.

In addition, the fixed frame 20 protrudes to form a support protrusion 30 on the upper side. In particular, the support protrusion 30 is formed to protrude on the upper side of the fixing frame 20 corresponding to the same side edge of each of the receiving port (24). In addition, the support protrusion 30 has a first inclined surface 32 on the same side, and has a recessed groove 34 open to both sides while being connected to the slide channel 22. Of course, the recess 34 may be formed to be opened only to the other side opposite to one side having the first inclined surface 32 of the support protrusion 30. In particular, the support protrusion 30 is preferably formed integrally with the fixed frame 20. And, the support protrusion 30 is preferably formed on the upper side. This is to allow the upper side of the support protrusion 30 to be in contact with the pressing member 60. In addition, the support protrusion 30 is preferably made of a mold or injection molded integrally with the fixed frame 20.

On the other hand, the moving frame 40 is provided on the upper side of the fixed frame 20. The moving frame 40 forms a communication hole 44 to communicate with the upper and lower in order to insert the support protrusion 30 of the fixed frame 20 to protrude upward. Thus, the communication hole 44 is preferably formed equal to the number of the support protrusions (30). Here, the communication hole 44 is formed to a size that can be inserted into the support protrusion 30 and the knob 52, which will be described later. At this time, the reason why the communication hole 44 is formed so as to project the support protrusions 30 in the upper direction is to allow the support protrusions 30 to be in direct surface contact with the pressing member 60 and to securely seat the wire harness. to be. In addition, the reason why the communication hole 44 inserts the knob 52 is to allow the moving frame 40 to be moved from one side of the support protrusion 30 to the other direction by the knob 52 by an external force. .

In addition, the moving frame 40 has a second slope 42 on the inner surface of the communication hole (44). In particular, a second inclined surface 42 is formed on the inner surface of the inner surface of the communication hole 44 opposite to the first inclined surface 32 of the inserted support protrusion 30. At this time, the first inclined surface 32 and the second inclined surface 42 are formed to be symmetric with each other. This is to allow the second inclined surface 42 to be firmly seated on wire harnesses of different diameters ascending or descending along the first inclined surface 32. That is, when the second slope 42 is lowered along the first slope 32, a relatively thick wire harness may be seated between the first slope 32 and the second slope 42. On the contrary, when the second inclined surface 42 rises along the first inclined surface 32, a wire harness having a relatively small diameter may be seated between the first inclined surface 32 and the second inclined surface 42.

Therefore, the moving frame 40 moves forward or descends while being moved up or down by the second inclined surface 42 moving along the first inclined surface 32 when being pushed or pulled along the axial direction of the fixed frame 20 by an external force. You will reverse.

Of course, the inner surface or the edge of the communication hole 44 may not form an inclined surface symmetrical with the first inclined surface 32, but the moving frame 40 to raise the second inclined surface 42 to maintain the horizontal Have The reason why the moving frame 40 is raised and lowered while maintaining the horizontal is to prevent deformation such as bending of the wire harness interposed between the transfer frame and the pressing member 60.

7 to 9 illustrate the moving frame 40.

On the other hand, the moving frame 40 is capable of reciprocating movement by the operating unit (50). In particular, the operation unit 50 is inserted into the slide channel 22, is accommodated in the communication port 44 of the receiving port 24 and the movable frame 40 of the fixed frame 20 to support the movable frame 40 While inducing rise and fall.

Here, the operation unit 50 includes a slide member 51, the knob 52 and the operation member 53.

The slide member 51 is inserted into the slide channel 22. The slide member 51 is sized to be reciprocally inserted in the slide channel 22 and can be deformed into various shapes. In particular, when the slide channel 22 is opened to the lower side of the fixed frame 20, the slide member 51 is supported by the base frame 10 and moved.

The knob 52 protrudes upward from the slide member 51. At this time, the knob 52 is protruded by the number of the receiving port 24 is accommodated in the corresponding receiving port 24 and the communication hole 44. In particular, since the knob 52 is inserted into the receiving port 24 and the communication hole 44 to protrude upward, the slide channel 22 is preferably formed to open in the lower direction of the fixed frame 20. The knob 52 can be modified in various shapes. In addition, the slide member 51 and the knob 52 is preferably formed integrally.

Further, the slide member 51 is forcibly linearly reciprocated by the operation member 53, and the slide frame 51 is moved so that the moving frame 40 is moved by the slide member 51 at the same time. In particular, the recessed groove 34 of the support protrusion 30 accommodates a part or the whole of the knob 52 therein.

At this time, when the recessed groove 34 is opened only to the other side of the support protrusion 30, the knob 52 acts to push the moving frame 40 in one direction by the operation member 53 (forward). Thus, the second inclined surface 42 of the communication hole 44 ascends along the first inclined surface 32 of the support protrusion 30 and the movable frame 40 is raised. In this case, when the slide member 51 is moved in the opposite direction by the operating member 53, the moving frame 40 is returned to the original position (backward) by the operator.

Although not shown, when the recess 34 is opened to both sides of the support protrusion 30, the movable frame 40 is pushed when the knob 52 pushes the movable frame 40 in one direction by the operating member 53. Will rise. On the contrary, when the knob 52 pushes the moving frame 40 in the other direction by the operating member 53, the moving frame 40 is lowered.

Here, the operation member 53 includes an operation block 54, a fixed block 55, a screw shaft member 56 and a nut member 57.

The operation block 54 is formed at one end of the slide member 51, and the fixed block 55 is formed at one end of the fixed frame 20. At this time, the operation block 54 is formed integrally with the slide member 51, the fixed block 55 is preferably formed integrally with the fixed frame 20.

In addition, the screw shaft member 56 is inserted into the fixed block 55, and is bound to the operation block (54). In particular, the screw shaft member 56 forms a screw thread on the circumferential surface and is fixed by screwing one side to the operation block 54.

Then, the nut member 57 is screwed to the other side, and is in contact with the outer surface of the fixing block 55. In particular, the nut member 57 is preferably inserted into the fixing block 55 to be fixed to both sides. Thus, when the nut member 57 is forcibly rotated by an external force, the nut member 57 is fixed in position, and the screw shaft member 56 is reciprocated along the axial direction. At this time, since the operation block 54 of the slide member 51 is bound to the screw shaft member 56, the slide member 51 is moved in the same direction as the screw shaft member 56. As a result, the knob 52 is forcibly pushed by the moving frame 40. Therefore, the second inclined surface 42 of the communication hole 44 is movable along the first inclined surface 32 of the support protrusion 30, thereby maintaining the moved state. Here, the nut member 57 is preferably a general nut.

On the other hand, the movable frame 40 is preferably formed recessed groove portion 74 to seat the wire harness. In more detail, the seating recess 74 is recessed on the upper side of the moving frame 40 corresponding to the upper side of the second inclined surface 42 to secure the wire harness between the first inclined surface 32 and the second inclined surface 42. It can be prevented from rolling by itself.

In addition, the moving frame 40 is preferably provided with a recess groove 76 for receiving each of the operation block 54 and the knob 52. The concave groove 76 serves to minimize the shaking of the moving frame 40 by receiving the corresponding operation block 54 and the knob 52.

The base frame 10, the fixed frame 20 and the moving frame 40 are assembled by the above-described configuration. Then, the operation member 53 is operated to determine the position of the second inclined surface 42 with respect to the first inclined surface 32. Then, when the wire harness is seated in the seating groove portion 74, the pressing member 60 presses the wire harness to fix it.

In particular, the pressing member 60 serves to pressurize and fix the seated wire harness while being detachably coupled to the upper side of the support protrusion 30. The pressing member 60 is preferably formed in a plate shape to firmly pressurize the wire harness. In addition, it is preferable that the pressing member 60 is detachably fixed to the support protrusion 30 as the fastening member 5.

In more detail, each of the fastening members 5 is inserted into the pressing member 60 and the fixed frame 20 in order. At this time, the lower side of the fastening member 5 protrudes to the bottom of the fixing frame 20, the elastic member 80 is inserted into the protruding portion. In addition, the lower end of the fastening member 5 is coupled to the snap ring 82 to prevent the lower departure of the elastic member (80). At this time, the fastening member 5 is preferably formed on both sides of one pressing member (60).

Accordingly, since the elastic member 80 is supported by the snap ring 82 and pushes the fixed frame 20 toward the pressing member 60, the wire harness seated between the pressing member 60 and the moving frame 40 is burnt. Sexually firmly pressurized. At this time, the elastic member 80 is preferably a coil spring.

In addition, the binding member 6 is fastened to each of the pressing members 60. The lower end of the binding member 6 is in contact with the upper surface of the support protrusion 30. Thus, the binding member 6 serves to maintain the gap between the fixed frame 20 and the pressing member 60.

Thus, both sides of the wire harness are fixed. At this time, the wire harness is a test target for a test such as a bending test, and by changing the position of the moving frame 40 so that the center of the curved surface is always matched according to the thickness can be adjusted the distance between the two edges of the wire harness Will be.
