For example, in an electrical connector assembly and its wire harness, in some installation and routing environments, the wire harness and the connection between the wire harness and the electrical connector are often bent due to the influence of installation space and position, which may cause damage to the bent part and thus affect the safety of the connected object and its affiliated equipment. Therefore, the tensile strength and bending resistance of the electrical connector assembly and its wire harness are particularly important. These mechanical properties determine the stability and reliability of the electrical connector when subjected to various external forces. Therefore, performing a tensile test on the electrical connector assembly and its wire harness before leaving the factory is a key link to ensure product quality.

The terms used in the description of this utility model herein are only for the purpose of describing specific embodiments, and are not intended to limit this utility model.
[0045] Please refer to Figure 1 , Figure 1 which shows a schematic structural diagram of one embodiment of the universal test tooling 1000. Figure 1In the illustrated embodiment, the universal test tooling 1000 is exemplarily described by taking an electrical connector assembly and its wire harness as the device under test. The universal test tooling 1000 is used to fix the electrical connector assembly and its wire harness at multiple angles when testing the docking performance of the first electrical connector and the second electrical connector of the electrical connector assembly, the connection performance between the wire harness and the first electrical connector and / or the second electrical connector, and the bending performance at the connection, so that the electrical connector assembly and its wire harness can be tested at multiple angles, thereby meeting the test standards of electrical connector assemblies and their wire harnesses in different industries.
[0046] Exemplarily, this embodiment is described by taking the board-to-wire electrical connector assembly 100 as the product to be clamped. The first electrical connector 110 of the board-to-wire electrical connector assembly 100 is a board-end connector, which is welded to the circuit board 120; the second electrical connector 130 is a wire-end connector, one end of which is docked with the board-end connector and the other end of which is connected to the wire harness 140. The universal test tooling 1000 is used to fix the circuit board 120 when testing the board-to-wire electrical connector assembly 100 and its wire harness 140, and thereby indirectly fix the board-end connector and the wire-end connector. It should be understood that the tooling for testing the electrical connector assembly and its wire harness 140 of the present invention is not limited to fixing the board-to-wire electrical connector assembly 100, and can also be used for fixing during the test of the wire-to-wire electrical connector assembly. Only the structure of the clamping part in the following text needs to be adjusted adaptively.
[0047] The universal test tooling 1000 includes a fixed seat 200, a horizontal bracket 300 that can be fixed on the fixed seat 200 after rotating a corresponding angle in the horizontal direction, and a vertical fixing mechanism 400 that can be fixed on the horizontal bracket 300 after flipping a corresponding angle in the vertical direction. A clamping part 410 for clamping the board-to-wire electrical connector assembly 100 and its wire harness 140 is provided on the vertical fixing mechanism 400.
[0048] Please refer to Figure 2, the fixing base 200 can be in the form of a plate, a block, a table, or any other structure that can be used to fix the horizontal bracket 300. In the illustrated embodiment, the fixing base 200 has an overall elongated structure. A set of first fixing row holes 210 are provided on the fixing base 200 and are distributed along the length direction of the fixing base 200. The first fixing row holes 210 include at least two spaced-apart first fixing holes 211, and the at least two spaced-apart first fixing holes 211 are distributed on the upper end surface of the fixing base 200 along the length direction of the fixing base 200. Specifically, the first fixing row holes 210 include three evenly spaced first fixing holes 211. Among them, the first fixing hole located in the middle is defined as the first central hole 212, and the remaining two first fixing holes 211 are symmetrically distributed on both sides of the first central hole 212. The first fixing row holes 210 may also include an odd number of first fixing holes 211 greater than one, such as five, seven, nine, etc., which are evenly spaced. The first fixing hole located in the middle is defined as the first central hole 212, and the remaining even number of first fixing holes 211 are symmetrically distributed on both sides of the first central hole 212. It should be understood that the first fixing row holes 210 are not limited to being distributed along the length direction of the fixing base 200, but may also be linearly distributed along the width direction or obliquely. When the fixing base 200 is a cylinder, the first fixing row holes 210 may also be distributed along the radial direction of the cylinder.
[0049] Please refer to Figure 3 , a number of groups of second fixing row holes 310 corresponding to the first fixing row holes 210 are provided on the horizontal bracket 300. The orientations of each group of the second fixing row holes 310 in the horizontal direction are all different, and the number of holes and the spacing distance of each group of second fixing row holes 310 correspond to the number of holes and the spacing distance of the first fixing row holes 210. Each group of the second fixing row holes 310 includes at least two spaced-apart second fixing holes 311 that correspond one-to-one to at least two first fixing holes 211. By providing a number of groups of second fixing row holes 310 distributed in different horizontal directions, when fixing the horizontal bracket 300 to the fixing base 200, one group of second fixing row holes 310 with a corresponding orientation can be selectively aligned with the first fixing row holes 210 on the fixing base 200 according to the test requirements, and then the first fixing holes 211 and the second fixing holes 311 are locked by fixing bolts 313, so that the horizontal bracket 300 can be fixed at the corresponding angle.
[0050] Specifically, each group of the second fixed row of holes 310 includes three second fixed holes 311 evenly spaced apart. Among them, the second fixed hole 311 located in the middle is defined as the second center hole 312, and the remaining two second fixed holes 311 are distributed opposite to each other on both sides of the second center hole 312. The second fixed row of holes 310 may also include an odd number of second fixed holes 311 greater than one, such as five, seven, nine, etc., evenly spaced apart. The second fixed hole 311 located in the middle is defined as the second center hole 312, and the remaining even number of second fixed holes 311 are symmetrically distributed on both sides of the second center hole 312. Preferably, in order to reduce the number of holes, several groups of the second fixed row of holes 310 share a second center hole 312. The second fixed holes 311 of each group of the second fixed row of holes 310 are symmetrically distributed on both sides of the second center hole 312, and the second fixed holes 311 of all the second fixed row of holes 310 are distributed in a circular array around the second center hole 312.
[0051] In other embodiments, the installation positions of the first fixed row of holes 210 and several groups of the second fixed row of holes 310 can be swapped with each other. For example, a group of the first fixed row of holes 210 is arranged at the bottom of the horizontal bracket 300, and several groups of the second fixed row of holes 310 are arranged at the top of the fixed seat 200. Except for the position swap, the other structural features, quantity, and distribution patterns of the first fixed row of holes 210 and several groups of the second fixed row of holes 310 are the same as those of the first fixed row of holes 210 and several groups of the second fixed row of holes 310 described above. The orientations of each group of the second fixed row of holes 310 in the horizontal direction are all different; when fixing the horizontal bracket 300 to the fixed seat 200, one group of the second fixed row of holes 310 is selected to be fixed to the first fixed row of holes 210.
[0052] The horizontal bracket 300 includes a bottom plate 320 and two side frames 330 erected on the bottom plate 320. The first fixed row of holes 210 or several groups of the second fixed row of holes 310 are arranged on the bottom plate 320. The two side frames 330 and the bottom plate 320 enclose a U-shaped assembly space 340 for assembling the vertical fixing mechanism 400. The vertical fixing mechanism 400 can be fixed in the U-shaped assembly space 340 after being flipped by a corresponding angle in the vertical direction.
[0053] The third fixed row of holes 350 is provided on each of the two side frames 330. The distribution of the third fixed row of holes 350 can be similar to that of the first fixed row of holes 210, both being linearly arranged. For example, the third fixed row of holes 350 includes at least two spaced-apart third fixed holes 351. The third fixed row of holes 350 can also have different distribution patterns, such as being distributed in a triangular array, a rectangular array, an annular array, an arc array, etc. To improve the fixing stability with the vertical fixing mechanism 400, the third fixed row of holes 350 further includes at least three third fixed holes 351 (four third fixed holes 351 in this embodiment). One of the third fixed holes 351 is close to the upper end of the side frame 330 and is defined as the third center hole 352. The remaining third fixed holes 351 are all distributed below the third fixed hole 351, and the distance between each third fixed hole 351 and the third center hole 352 is the same. They are distributed in an arc array centered on the third center hole 352. In the illustrated embodiment, the third fixed row of holes 350 includes a third center hole 352 provided close to the upper end of the side frame 330 and three third fixed holes 351 distributed below the third center hole 352 (one of which can be used as a reserved hole to meet the requirements of different test scenarios). The spacing distances between the three third fixed holes 351 are the same, and the spacing distance between each third fixed hole 351 and the third center hole 352 is the same. They are all arranged around the outer periphery of the third center hole 352.
[0054] Please refer to Figure 4 and Figure 5 , the vertical fixing mechanism 400 includes two fixing plates 430 corresponding to the two side frames 330 and the clamping portion 410 connected between the two fixing plates 430. At the position corresponding to the third fixed row of holes 350 of each side frame 330 on each fixing plate 430, a number of groups of fourth fixed rows of holes 420 corresponding to the third fixed row of holes 350 are provided. The distribution directions of each group of the fourth fixed rows of holes 420 are all different, and the number of holes and the spacing distance of each group of the fourth fixed rows of holes 420 correspond to the number of holes and the spacing distance of the third fixed row of holes 350. Each group of the fourth fixed rows of holes 420 includes at least two spaced-apart fourth fixed holes 421 corresponding one-to-one to at least two third fixed holes 351. By providing a number of groups of fourth fixed rows of holes 420 distributed on the fixing plate 430 in different directions, when the vertical fixing mechanism 400 is fixed to the two side frames 330, one group of corresponding fourth fixed rows of holes 420 with a corresponding orientation can be selectively selected to be aligned with the third fixed row of holes 350 on the side frame 330 according to the test requirements, and then the third fixed hole 351 and the fourth fixed hole 421 are locked by a fixing bolt.
[0055] In the illustrated embodiment, each set of the fourth fixed row of holes 420 includes a fourth central hole 422 and a plurality of fourth fixed holes 421, and the plurality of fourth fixed holes 421 and the fourth central hole 422 are distributed in an arc array centered thereon. The number of holes and the spacing distance of each set of the fourth central holes 422 and the fourth fixed holes 421 correspond to the number of holes and the spacing distance of the third central holes 352 and the third fixed holes 351. Preferably, in order to reduce the number of hole positions, all sets of the fourth fixed rows of holes 420 share a fourth central hole 422, and all the fourth fixed holes 421 are distributed in an arc or circular array around the fourth central hole 422.

The clamping portion 410 includes a back plate 413 connected between the two fixing plates 430 and a panel 414 detachably fixed to one side of the back plate 413. The distance-adjustable clamping cavity 411 is formed between the back plate 413 and the panel 414, and the window 412 is provided on the back plate 413 and / or the panel 414 for the power supply connector assembly and its wire harness 140 to be exposed.

The horizontal bracket rotates horizontally around the second central hole, and two second fixed holes on the same diameter and the second central hole are paired to form a second fixed row hole. Several groups of second fixed row holes are distributed on diameters in different orientations, so that several angle adjustments within 360 degrees can be achieved. When it is necessary to adjust the corresponding angle in the horizontal direction, rotate the horizontal bracket around the second central hole to align the two second fixed holes and the second central hole on the corresponding diameter with the two first fixed holes and the first central hole of the first fixed row hole on the fixed seat one by one, and the horizontal angle adjustment and fixation of the horizontal bracket can be realized.
