[0032] The purpose of this application is to overcome the above-mentioned technical deficiencies and propose a fixing tool and fixing system for a test harness to solve the technical problem in the prior art that the harness has the risk of falling and being damaged.

[0033] In order to achieve the above technical objectives, this application adopts the following technical solutions:

[0034] In the first aspect, the present application provides a fixture for testing a wiring harness, such as Figure 1 and Figure 2 As shown, Figure 1 This is a schematic structural diagram of a fixing fixture for a test harness provided in an embodiment of the present application; Figure 2 This is an exploded schematic diagram of a fixing tool for a test harness provided in an embodiment of the present application.

[0035] A fixture for testing a wiring harness, comprising a frame assembly 1, a limit assembly 2, and a positioning member 3:

[0036] A frame assembly 1, wherein the inner side of the frame assembly 1 has a receiving space;

[0037] A limiting assembly 2, the limiting assembly 2 being located in the accommodating space, the limiting assembly 2 comprising a first pressing block 21 and a second pressing block 22 arranged opposite to each other, the first pressing block 21 and the second pressing block 22 being elastically connected to the frame assembly 1 respectively, the sidewalls of the first pressing block 21 and the sidewalls of the second pressing block 22 both having notches, the two notches being located on the same side and interconnected; and

[0038] The positioning member 3 is located on a side surface of the first pressing block 21 facing the second pressing block 22 and / or on a side surface of the second pressing block 22 facing the first pressing block 21 .

[0039] In the embodiment of the present application, through the cooperation of the frame assembly 1 and the limit assembly 2, the test terminal 6 extends from the notch of the first pressure block 21 and the second pressure block 22 until it is embedded in the positioning member 3. The test harness can be fixed in the tooling in the non-test state to prevent it from falling into the automatic line due to gravity or external factors. This not only avoids the production line shutdown caused by the falling harness, but also reduces the risk of the harness being damaged by the production line equipment. The notch design on the side walls of the first pressure block 21 and the second pressure block 22, as well as the elastic connection between the limit assembly 2 and the frame assembly 1, can ensure that the harness is not subjected to excessive pressure when fixed, thereby reducing the risk of the harness being damaged due to extrusion or friction. This improves production efficiency, ensures production safety, extends the service life of the harness, maintains production order, and facilitates operation and maintenance.

[0040] like Figure 3 As shown, Figure 3 It is a cross-sectional schematic diagram of a fixing system for a test harness provided in an embodiment of the present application.

[0041] In some embodiments of the present application, the outline of the positioning member 3 is a hemisphere, and the bottom surface of the hemisphere is arranged on the surface of the first pressing block 21 and / or the second pressing block 22 .

[0042] In this embodiment, the test terminal 6 contacts the hemispherical curved surface of the positioning member 3 , and the contact area gradually increases until the center of the circular groove of the test terminal 6 coincides with the center of the hemispherical curved surface.

[0043] The hemispherical shape evenly distributes pressure at the harness contact points, preventing damage to the harness caused by excessive local pressure. The hemispherical design automatically centers the harness during fixation, ensuring symmetry between the clamps and improving fixation stability.

[0044] In some embodiments of the present application, the frame assembly 1 includes a first fixed block 11, a first guide block 12, a second fixed block 13 and a second guide block 14 connected in sequence end to end, the first fixed block 11 and the second fixed block 13 are arranged opposite to each other, and the first guide block 12 and the second guide block 14 are arranged opposite to each other.

[0045] In this embodiment, the arrangement of the first guide block 12 and the second guide block 14 can guide the limiting assembly 2 to be fixed in the X and Y directions, and move only in the Z direction, thereby ensuring the alignment accuracy of the wiring harness during the fixing process. The relative arrangement of the first fixing block 11 and the second fixing block 13 can respectively fix the first pressing block 21 and the second pressing block 22. The first pressing block 21 and the second pressing block 22 provide a double-sided fixing effect on the test terminal 6, thereby enhancing the fixing effect of the wiring harness and preventing the wiring harness from moving during the fixing process.

[0046] In some embodiments of the present application, a plurality of connecting bolts 4 are further included, the first pressing block 21 has a first threaded hole, the second pressing block 22 has a second threaded hole, the first fixing block 11 is threadedly connected to the first pressing block 21 by the connecting bolts 4 passing through the first threaded hole, and the second fixing block 13 is threadedly connected to the second pressing block 22 by the connecting bolts 4 passing through the second threaded hole.

[0047] In this embodiment, the threaded connection provides a strong fastening force, ensuring that the connection between the pressing block and the fixing block is stable and reliable and not easy to loosen.

[0048] In some embodiments of the present application, the number of the first threaded holes and the number of the second threaded holes are both no less than two, wherein the two first threaded holes are symmetrically distributed about the axis of the first pressing block 21 , and wherein the two second threaded holes are symmetrically distributed about the axis of the second pressing block 22 .

[0049] In this embodiment, the symmetrically distributed threaded holes ensure that the clamp is subjected to more uniform force when securing the wiring harness, reducing damage to the wiring harness caused by excessive force at a single point. It also ensures that both ends of the clamp move simultaneously in the Z direction, preventing excessive force at one end from tilting the clamp and unevenly applying force to the wiring harness.

[0050] In some embodiments of the present application, the first pressing block 21 and the first fixing block 11 are distributed parallel to each other, and the second pressing block 22 and the second fixing block 13 are distributed parallel to each other.

[0051] In this embodiment, the multiple connecting bolts 4 passing through the first pressing block 21 are of equal height, and the multiple connecting bolts 4 passing through the second pressing block 22 are of equal height. The connecting bolts 4 passing through the first pressing block 21 and the connecting bolts 4 passing through the second pressing block 22 may or may not be equal in height. Because the pressing blocks are parallel to the fixing blocks and are evenly spaced, the pressure applied to the wiring harness is evenly distributed, reducing the risk of damage to the wiring harness due to excessive local pressure.

[0052] In some embodiments of the present application, a plurality of springs 5 are further included, each of the springs 5 is sleeved on the outside of one of the connecting bolts 4, and the two ends of the spring 5 are respectively in contact with the first pressure block 21 and the first fixing block 11, or in contact with the second pressure block 22 and the second fixing block 13.

[0053] In this embodiment, spring 5 maintains constant pressure on the harness, preventing it from loosening even under external forces. The elastic properties of spring 5 allow the harness to remain fixed even with slight dimensional changes, increasing the adaptability of the fixture.

[0054] In some embodiments of the present application, the first guide block 12 has a first guide groove 121 opening toward the second guide block 14, the second guide block 14 has a second guide groove 121 opening toward the first guide block 12, the two ends of the first pressing block 21 are respectively slidably connected to the first guide groove 121 and the second guide groove 121, and the two ends of the second pressing block 22 are respectively slidably connected to the first guide groove 121 and the second guide groove 121.

[0055] In this embodiment, the guide groove 121 provides a precise guide path, ensuring the correct position of the clamp when securing the wire harness, thereby improving the accuracy of the securing. The guide groove 121 helps maintain the alignment of the clamp and the wire harness, ensuring that the wire harness does not twist or shift during the securing process.

[0056] In a second aspect, the present application further provides a fixing system for a test harness, comprising a test terminal 6 and a fixing fixture for the test harness as described in any one of the embodiments in the first aspect, wherein the test terminal 6 is fixedly connected to the fixing fixture for the test harness.

[0057] In some embodiments of the present application, one end of the test terminal 6 has a groove, the opening of the groove faces the positioning member 3, and the positioning member 3 is embedded in the groove.

[0058] In this embodiment, the overall tooling is fixed to the linear device using bolts through bolt holes.

[0059] The tooling spring 5 is ensured to be in a stressed and compressed state in a natural state, and the first pressing block 21 and the second pressing block 22 are fitted on both sides.

[0060] The wiring harness terminal enters through the boss position of the second pressing block 22 (the left and right limit of the boss ensures that the terminal enters vertically, and the forward direction of the second pressing block 22 is limited by the boss).

[0061] When the terminal moves forward, the hemispherical protrusion in the second pressing block 22 is subjected to force, and the first pressing block 21 and the second pressing block 22 move up and down through the guide groove 121 on the guide block.

[0062] The terminal rebounds through the hemispherical rear spring 5, and the upper and lower pressure blocks fit together, completing the entire process of wiring harness fixing.

[0063] Compared with the existing technology, the technical solution provided by this application brings the following beneficial technical effects:

[0064] In the embodiment of the present application, through the cooperation of the frame assembly 1 and the limit assembly 2, the test terminal 6 extends from the notch of the first pressure block 21 and the second pressure block 22 until it is embedded in the positioning member 3. The test harness can be fixed in the tooling in the non-test state to prevent it from falling into the automatic line due to gravity or external factors. This not only avoids the production line shutdown caused by the falling harness, but also reduces the risk of the harness being damaged by the production line equipment. The notch design on the side walls of the first pressure block 21 and the second pressure block 22, as well as the elastic connection between the limit assembly 2 and the frame assembly 1, can ensure that the harness is not subjected to excessive pressure when fixed, thereby reducing the risk of the harness being damaged due to extrusion or friction. This improves production efficiency, ensures production safety, extends the service life of the harness, maintains production order, and facilitates operation and maintenance.

[0065] Those skilled in the art will understand that the various operations, methods, steps, measures, and schemes in the processes discussed in this application may be alternated, changed, rearranged, decomposed, combined, or deleted.

[0066] The specific implementation methods of the present application described above do not limit the scope of protection of the present application.
