[0023] To illustrate the technical content of the utility model, the purposes and effects achieved, the following will be described in conjunction with the embodiments and the accompanying drawings.

[0024] In modern electrical equipment and systems, the wiring harness assembly is a key part to realize electrical connection, which is generally composed of an insulating sheath, a terminal, a wire and an insulating wrapping material. However, the existing wiring harness assembly has some problems in actual application, mainly in the connection mode and overall structure of the pre-insulated terminal.

[0025] Firstly, the commonly used pre-insulated terminal has obvious deficiencies in the connection mode. The existing terminal connection part mainly has two shapes of round and fork type, and these two types of terminals each have defects. Although the round connection terminal is reliable in connection and not easy to loosen in normal use, it must be completely removed when installing or removing the wire. This operation process is tedious, especially in a small space, it is difficult to operate, the installation difficulty is extremely great, which seriously affects the installation convenience. For example, in some precision instruments, the operation space is extremely limited, and the operation technology requirement for the installer is extremely high, which increases the installation cost and time cost.

[0026] In comparison, the fork terminal is relatively convenient to use, but it has serious safety hazards and is prone to fall off during use. This falling off not only reduces the conductivity and causes the connection to be interrupted, affecting the normal operation of the electrical equipment, but also may cause serious safety accidents in the fields of medical devices, aerospace, etc. which have extremely high safety requirements. For example, in medical devices, connection interruption may cause deviation in patient monitoring or treatment, endangering the patient's life and health; in the field of aerospace, connection failure may affect the normal flight of the aircraft, causing incalculable losses.

[0027] Secondly, most of the existing wiring harness assemblies adopt a fixed structure, and once the terminal opening size is determined, it cannot be changed, and it cannot be adjusted according to actual needs, which makes the wiring harness assembly have great limitations when adapting to different scenes. Different electrical equipment and application scenarios have different requirements for terminal opening size and wire length, and the fixed structure of the wiring harness assembly is difficult to meet the diversified needs, resulting in waste of resources and inconvenience of use. In addition, inappropriate connection mode will also reduce the conductivity and reliability, further aggravating the risk in the operation of electrical equipment, which may cause safety hazards and affect the stability of the entire electrical system.

[0028] Therefore, please refer to Figure 1 andFigure 2 The utility model provides a kind of wiring harness assembly, it includes terminal (that is pre-insulated terminal) 1 and wire 2, the terminal 1 includes metal connecting part and wire clamp part, the wire clamp part one end is connected with the wire 2, the other end is connected with the metal connecting part, the metal connecting part includes first bolt 12 and two conductive metal sheets 13, one end of two conductive metal sheets 13 is rotatably connected by first bolt 12.

[0029] In practical application, two conductive metal sheets 13 are connected together by intermediate screw, and jointly constitute metal connecting part. When installing this terminal 1, it is necessary to open this terminal 1 first, place terminal 1 at the second bolt 3 to be connected, then adjust the included angle size of two conductive metal sheets 13 by rotating first bolt 12 to clamp second bolt 3, then tighten first bolt 12 connecting two conductive metal sheets 13, and finally lock second bolt 3. It should be noted that the size range of first bolt 12 that can be locked by metal connecting part can be set according to actual situation, such as the size can be M4~M10. The wiring harness assembly of the utility model can adjust the opening size of terminal 1 according to the size of second bolt 3 to be fixed in use. In addition, it should be noted that the wire pressing diameter range of terminal wire clamp part can be 0.5-4mm².

[0030] From the above description, the utility model has the beneficial effects that the utility model provides a wiring harness assembly with variable opening size of terminal 1. The utility model sets corresponding terminal 1 at the end of wire 2, and the metal connecting part of terminal 1 includes two conductive metal sheets 13. One end of the two conductive metal sheets 13 is rotatably connected by first bolt 12. When installing, first bolt 12 can be loosened to make two conductive metal sheets 13 rotatable. At this time, the included angle of two conductive metal sheets 13 is adjusted, the opening size of terminal 1 is adjusted correspondingly, so as to adapt to second bolt 3 of different sizes. After the opening size of terminal 1 is adapted to second bolt 3, first bolt 12 can be tightened for locking and fixing. When disassembling, first bolt 12 is loosened, and then the terminal 1 is opened left and right, which can be taken out. Based on the above metal connecting part, the opening size of terminal 1 is variable, so as to be compatible with second bolt 3 of different sizes, solve the poor applicability problem in prior art, and significantly improve the application flexibility and applicability of wiring harness assembly.

[0031] As Figure 1As shown, the second bolt 3 on the left has a smaller diameter, and correspondingly, the included angle of the two conductive metal sheets 13 on the left can be adjusted smaller, that is, the opening of the terminal 1 can be adjusted smaller; the second bolt 3 on the right has a larger diameter, and correspondingly, the included angle of the two conductive metal sheets 13 on the right can be adjusted larger, that is, the opening of the terminal 1 can be adjusted larger. In actual application, the first bolt 12 includes a screwed state and an unscrewed state, when the first bolt 12 is in the unscrewed state (that is, the first bolt 12 is unscrewed), the size of the opening formed by the two conductive metal sheets 13 (that is, the included angle between the two conductive metal sheets 13) can be adjusted, and when the first bolt 12 is in the screwed state (that is, the first bolt 12 is locked), the size of the opening formed by the two conductive metal sheets 13 cannot be adjusted.

[0032] In addition, in actual application, a corresponding first threaded hole can be formed on the two conductive metal sheets 13, and the first bolt 12 passes through the first threaded hole. Correspondingly, a second threaded hole can be formed on the wire clamping part, and the first bolt 12 is screwed into the first threaded hole and the second threaded hole to realize the connection of the two conductive metal sheets 13 and the wire clamping part, and at this time, the first bolt 12 can be adjusted to adjust the size of the opening formed by the two conductive metal sheets 13.

[0033] Further, in the wire harness assembly, two terminals 1 are connected to the two ends of the wire 2 through the wire clamping part.

[0034] Further, in the wire harness assembly, the conductive metal sheet 13 is in an arc shape, the conductive metal sheet 13 includes an arc-shaped notch 14, and the arc-shaped notches 14 of the two conductive metal sheets 13 are oppositely arranged; wherein the metal connecting part includes a clamped state and an unclamped state, when the metal connecting part is in the clamped state, the two arc-shaped notches 14 form a through hole (such as Figure 1 as shown in the terminal 1 on the left). The clamped state refers to the case that the included angle of the two conductive metal sheets 13 is the smallest, and the unclamped state refers to other cases except that the included angle of the two conductive metal sheets 13 is the smallest, and in the unclamped state, an opening is formed, such as Figure 1 as shown in the terminal 1 on the right.

[0035] As can be seen from the above description, since the conductive metal sheet 13 is in an arc shape, the front arc surface of the conductive metal sheet 13 can well hold the second bolt 3, and the connection is not easy to loosen in use, the connection stability is improved, and the terminal 1 of the utility model is more reliable and stable in connection.

[0036] Further, in the wire harness assembly, an insulating sleeve 11 is further included, and the insulating sleeve 11 is sleeved on the wire clamping part.

[0037] From the above description, the insulating sleeve 11 can be sleeved outside the wire clamping part, and the insulating sleeve 11 is usually made of a material with good insulating performance, such as polypropylene (PA66), polyvinyl chloride (PVC), etc. By setting the corresponding insulating sleeve 11, electrical insulation protection and mechanical protection can be provided to prevent the conductive metal part from contacting external objects or other conductors, avoid safety accidents such as short circuit and electric leakage, reduce the influence of the external environment on the metal connecting part and the wire clamping part, thereby prolonging the service life of the pre-insulated terminal.

[0038] Further, in the wire harness assembly, the wire 2 includes a first wire part 21 and a second wire part 22 connected to each other, the first wire part 21 has elasticity, and the first wire part 21 is arranged in a spring shape along the extension direction of the second wire part 22. It should be noted that the first wire part 21 as a whole presents a spring shape, that is, a spiral structure.

[0039] In actual application, the first wire part 21 is a spring wire, which is a special wire material different from ordinary wire materials in that the cladding layer of the spring wire is made of TPU material. The TPU material has a wide hardness range, and different hardness products can be obtained by changing the ratio of each reaction component of the TPU. With the increase of hardness, the product still maintains good elasticity. Based on this, the first wire part 21 in a spring shape can be stretched or contracted as required. In actual application, it can release different wire lengths according to different application scenarios, such as being able to stretch out 2000mm.

[0040] From the above description, the present application can realize flexible adjustment of the length of the wire 2, thereby being able to adapt to different application scenarios. The first wire part 21 in a spring shape adjusts the length of the wire harness, has strong applicability, can be applied in different scenarios at the same time, does not need to be customized, reduces the waste of cost resources, and saves space. In addition, the connecting wire harness composed of the spring-shaped wire 2 of the present application occupies less space than the traditional wire harness of the same length, and is better stored and transported.

[0041] Further, in the wire harness assembly, the wire harness box 4 is further provided, the wire harness box 4 is internally provided with an accommodating cavity, and the first wire part 21 is arranged in the accommodating cavity.

[0042] In actual application, the length of the wire harness box 4 is greater than the length of the spring wire in a natural state, so that when the spring wire is stretched, the wire harness box 4 has enough stretching space for the spring wire to stretch. In addition, the two side surfaces of the wire harness box 4 are both provided with through holes for the wire 2 to stretch out.

[0043] From the above description, by setting the wire harness box 4, the first wire part 21 in a spring shape can be effectively placed and protected, thereby ensuring the effective stretching and contraction of the first wire part 21.

[0044] Furthermore, the wire harness assembly described in this utility model also includes a fixing base 5, which is disposed on the wire harness box 4.

[0045] Furthermore, in the wire harness assembly described in this utility model, the fixing base 5 includes a base and a connecting rod, one end of the base is connected to the wire harness box 4, and the other end is connected to the connecting rod.

[0046] In practical applications, the connecting rod of the fixing seat 5 can be embedded in the corresponding slot, such as a round hole with a diameter of 6.5mm or a U-shaped hole with a short side length of 6.5mm, so as to limit and fix the fixing seat 5, thereby limiting and fixing the wire 2 and reducing the possibility of its displacement.

[0047] Furthermore, in the wire harness assembly described in this utility model, the wire harness box 4 has through holes on both sides for the wire 2 to extend out, and the through holes are connected to the receiving cavity.

[0048] As described above, corresponding through holes are opened on the side of the wire harness box 4 to facilitate the extension of the wire 2.

[0049] Furthermore, in the wire harness assembly described in this utility model, the conductive metal sheet 13 has a protrusion 15 at one end away from the wire clamping portion.

[0050] As can be seen from the above description, the corresponding protrusion 15 is provided. The front arc surface of the protrusion 15 secures the second bolt 3 well, making it less likely to loosen during use and ensuring the stability of the connection.

The relative rotatability of the two conductive metal pieces 13 allows for a variable angle between them. In this embodiment, the conductive metal pieces 13 are generally arc-shaped. The arc-shaped notches 14 of the two conductive metal pieces 13 in each terminal block 1 are arranged opposite each other to enclose and secure the second bolt 3. In addition, corresponding insulating sleeves 11 can be provided on the metal connecting part and the wire clamping part for insulation.
