Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to a wire pressing structure, an electronic control box assembly and an air conditioner. Background Art

[0002] Existing electrical appliances are all powered by a power connection wire. Especially for split air conditioners, in addition to being powered by a power cord to the whole machine, there are also power supply harnesses such as unit power cords and communication wires between the indoor and outdoor units of the air conditioner, so as to realize the linkage control of the indoor and outdoor whole machines. Due to different usage functions and different machine powers, different types of harnesses are used. To protect the power connection wire and make the wiring regular, and avoid the pulling off of the terminal due to pulling, the power connection wire needs to be fixed by a wire pressing and fixing structure.

[0003] When the wire diameter of the same machine is switched, or the tolerance range of the wire diameter is very large (for example: the tolerance range of some specification harnesses reaches more than 4 mm), different wire pressing and fixing structures need to be used in combination. This will cause the corresponding production line personnel to select the corresponding structure from a variety of similar wire pressing and fixing structures during the production process, and there is a risk of using the wrong materials. And a variety of different structures require a variety of different molds to be newly opened, which is not easy for mold management, production changeover, and modular unification; at the same time, during the after-sales installation process, the installer needs to identify the structures matched by different harnesses for fixing, and the workload is relatively large. Summary of the Utility Model

[0004] Aiming at the deficiencies in the prior art, the utility model provides a wire pressing structure, an electronic control box assembly and an air conditioner to solve the technical problem that the traditional wire pressing structure in the related art has poor versatility, and there is a need for wire pressing structures of different sizes for harnesses with large tolerances.

[0030] The realization of the purpose of the present utility model, its functional features and advantages will be further described with reference to the embodiments and the accompanying drawings. Detailed implementation manners

[0031] In order to make the purpose, technical solutions and beneficial effects of the present utility model more clear and understandable, the technical solutions in the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0032] In the embodiment of the present utility model, as Figures 1 - 4 shown, the wire pressing structure includes: a wire pressing base 1 and a first wire pressing cover 2; the first wire pressing cover 2 includes a large wire passing hole end 201 and a small wire passing hole end 202 that are communicated with each other, and one end of the large wire passing hole end 201 and the small wire passing hole end 202 can be selectively arranged on the wire pressing base 1 to define a first wire pressing space with the wire pressing base 1, and the other end is suspended relative to the wire pressing base 1.

[0033] Specifically, in the embodiment of the utility model, the wire crimping seat 1 and the first wire crimping cover 2 are stacked in sequence, and the two are detachably connected, so that the wire harness can be installed and fixed therebetween.

[0034] On the other hand, Figure 4 As shown, the first crimping cover 2 is formed with a groove, and the two ends of the groove are defined as a large wire hole end 201 and a small wire hole end 202, respectively. The apertures of the two ends are not equal, so as to form a large or small first crimping space after cooperating with the crimping seat 1, so as to adapt to wire harnesses of different sizes. Specifically, during installation, select a suitable end face according to the wire diameter of the wire harness and install it on the crimping seat 1. Figure 1 As shown, when a small-sized wire harness needs to be fixed, the small wire hole end 202 of the first wire crimping cover 2 can be fixed to the wire crimping seat 1; Figure 2 As shown, when a large-size wire harness needs to be fixed, the large wire hole end 201 of the first crimping cover 2 can be fixed to the crimping seat 1. At the same time, the crimping seat 1 and the first crimping cover 2 are detachably connected, which can facilitate the reasonable selection of the corresponding end face for installation and fixation on the one hand, and can facilitate the compression of the wire harness between the crimping seat 1 and the first crimping cover 2 on the other hand.

[0035] In addition, if Figure 2 As shown, after the large-size wire harness is fixed, since it still needs to pass through the small wire hole end 202, in order to avoid the first wire cover 2 from lifting up the small wire hole end 202 and causing the first wire cover 2 to lift up, the first wire cover 2 in this embodiment does not completely cover the wire seat 1; that is, when the large wire hole end 201 is fixed to the wire seat 1, the small wire hole end 202 is protruding outside the wire seat 1, and it is suspended relative to the wire seat 1 to leave enough space for the wire harness to avoid the binding of the wire harness and causing the first wire cover 2 to lift up. On the contrary, when the small wire hole end 202 is fixed to the wire seat 1, the fixed wire harness can directly pass through the large wire hole end 201 and is not affected. Furthermore, in order to achieve the above purpose, the size of the wire seat 1 is reduced, so that its contact area with external parts can be reduced, which is conducive to installation in electrical appliances with smaller space requirements. Of course, the large-size wire diameter wire harness and the small-size wire diameter wire harness described above can be the upper deviation and the lower deviation of the wire diameter of the same specification wire harness, or different wire harnesses.

[0036] In this embodiment, by setting a large wire through hole end 201 and a small wire through hole end 202 on the first wire crimping cover 2, different end faces can be selected according to the wire diameter during installation to take into account the installation of two wire diameter sizes at the same time, thereby reducing the number of overall parts and reducing the contact area between the overall wire crimping structure and external parts, thereby improving the versatility of the structure and facilitating installation in electrical appliances with smaller space requirements.

[0037] like Figure 3As shown, in one embodiment, the wire pressing seat 1 is provided with a through groove 101 for forming the first wire pressing space with the large wire passing hole end 201 or the small wire passing hole end 202. Specifically, in order to adapt to the cross-sectional size of the wire harness and provide clearance for it, in this embodiment, a through groove 101 is provided at one end of the wire pressing seat 1 facing the first wire pressing cover 2. This through groove 101 can form a large-sized first wire pressing space with the large wire passing hole end 201, or form a small-sized first wire pressing space with the small wire passing hole end 202, so as to facilitate the accommodation and fixation of wire harnesses of corresponding sizes. Of course, since the cross-sectional area of the wire harness is circular, the through groove 101 is arranged in an arc shape to match the wire harness.

[0038] As Figure 4 shown, in one embodiment, the large wire passing hole end 201 and the small wire passing hole end 202 are respectively arranged on opposite sides of the first wire pressing cover 2. Specifically, in order to facilitate the wire harness to pass through the first wire pressing cover 2 and to facilitate the selection of a suitable end face for installation on the wire pressing seat 1, in this embodiment, the large wire passing hole end 201 and the small wire passing hole end 202 are defined to be oppositely arranged, so that they can be rotated 180° to switch the positions of the two end faces; at the same time, the wire harness can linearly penetrate through the two end faces, avoiding bending and damage of the wire harness.

[0039] As Figure 4 shown, in one embodiment, the large wire passing hole end 201 and the small wire passing hole end 202 are respectively provided with a plurality of first threaded holes 203 and a plurality of second threaded holes 204, and one of the first threaded holes 203 and the second threaded holes 204 can be selectively arranged on the wire pressing seat 1 for the screw to be screwed in. Specifically, in order to realize the detachable connection between the wire pressing seat 1 and the first wire pressing cover 2, in this embodiment, the first threaded holes 203 and the second threaded holes 204 are respectively arranged at the large wire passing hole end 201 and the small wire passing hole end 202, so that they correspond one by one to the threaded holes arranged on the wire pressing seat 1, and the appropriate end face can be selected according to needs to detachably connect the wire pressing seat 1 and the first wire pressing cover 2 with screws.

[0040] As Figure 1 、 Figure 2 、 Figure 5 、 Figure 6As shown, in one embodiment, the wire pressing base 1 is detachably provided with a second wire pressing cover 4. The second wire pressing cover 4 is spaced apart from the first wire pressing cover 2, and a plurality of second wire pressing spaces are defined between the second wire pressing cover 4 and the wire pressing base 1. The sizes of the plurality of second wire pressing spaces are at least partially equal or at least partially unequal. Specifically, in order to install multiple wire harnesses at the wire pressing base 1, in this embodiment, by providing the second wire pressing cover 4 on the wire pressing base 1, a second wire pressing space can be formed between the two, facilitating the installation of another wire harness. Similarly, the detachable connection method of the two facilitates fixing the wire harness on the wire pressing base 1 through the second wire pressing cover 4 after the wire harness is placed. In addition, the number of the formed second wire pressing spaces can be multiple, and the sizes can be (partially) equal, so that wire harnesses of the same specification can be fixed; or the sizes can be (partially) unequal, for accommodating wire harnesses of different sizes, further improving the versatility of this structure.

[0041] As Figure 5 , Figure 6 shown, in one embodiment, one of the wire pressing base 1 and the second wire pressing cover 4 is provided with a limiting groove 5, and the other is provided with a wedge-shaped protrusion 6. The limiting groove 5 and the wedge-shaped protrusion 6 are in plug-in fit. Specifically, in order to reduce the amount of screws used, in this embodiment, by respectively providing the limiting groove 5 and the wedge-shaped protrusion 6 on the wire pressing base 1 and the second wire pressing cover 4, the detachable connection is realized through their plug-in fit. Or, the limiting groove 5 and the wedge-shaped protrusion 6 are provided at the same end of the two, and the other ends of the two are connected by screws, which can also reduce the amount of screws used. In other embodiments, the wire pressing base 1 and the second wire pressing cover 4 can also be directly fixed by screws, and reasonable distribution of the positions of the screws can also reduce their amount.

[0042] As Figure 4 shown, the first wire pressing cover 2 is provided with a plurality of reinforcing ribs 3 for improving the structural strength of the first wire pressing cover 2. Similarly, as Figure 6 shown, reinforcing ribs can also be provided on the second wire pressing cover 4.

[0043] As Figure 7 shown, to achieve the above object, an embodiment of the present utility model provides an electric control box assembly, including: an electric control mounting plate 7 and a wire pressing structure. The wire pressing base 1 is detachably provided on the electric control mounting plate 7. This wire pressing structure is the wire pressing structure described above. Specifically, for the specific structure of the wire pressing structure, refer to the above embodiment. Since this electric control box assembly adopts all the technical solutions of the above embodiment, it at least has all the beneficial effects brought by the technical solutions of the above embodiment, and will not be elaborated here one by one. Among them, the above-mentioned screws (that is, the screws connecting the wire pressing base 1 and the first wire pressing cover 2 and / or the screws connecting the wire pressing base 1 and the second wire pressing cover 4) are finally screwed into the electric control mounting plate 7 (flanging hole) at the bottom, for preventing the entire wire pressing plate 1 from being pulled off during the wire harness tensile test.

[0044] Preferably, as Figure 7 shown, one of the wire pressing base 1 and the electric control mounting plate 7 is provided with a buckle 8, and the other is provided with a slot 9, and the buckle 8 is engaged with the slot 9.
