Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, in particular to a wire pressing device and an air conditioner having the same. Background Art

[0002] Air conditioners are essential household appliances in today's lives. They primarily consist of a cooling system, ventilation system, electrical system, cabinet, and panel. Air conditioners allow users to adjust and control parameters such as temperature, humidity, and air flow within buildings or structures, providing a more comfortable living environment.

[0003] An air conditioner consists of an outdoor unit and an indoor unit. An electrical box is fixed inside the housing of the indoor unit. The box primarily houses and protects important components such as the electronic control panel that controls the air conditioner's operation, as well as the wiring harness for the electrical wiring. The box is typically also equipped with a wire-crimping device for securing the power cord. Conventional wire-crimping devices press the power cord into a groove within the box. A wire-crimping clamp is then secured to the box using bolts, securing the power cord securely.

[0004] However, when the power cord harness is subjected to a pull-off test, the power cord is easily displaced by the pull-off force because the direction of the force applied to the power cord is the same as the direction of the power cord harness, causing the wire pressing device to fail.

[0005] Therefore, this field needs a new technical solution to solve the above problems. Summary of the Invention

[0006] In order to solve the above-mentioned problem in the prior art, that is, to solve the technical problem that the wire pressing device in the prior art cannot change the direction of the wire harness and thus causes the wire harness to be easily pulled off when subjected to force, the present invention provides a wire pressing device. The wire pressing device includes: a wire pressing portion, which has a wire pressing surface configured to press the target wire harness and a first side surface intersecting with the wire pressing surface; an extension portion, which extends vertically outward from the first side surface and has an outer end away from the first side surface and opposite second and third side surfaces; and a clamping ring, which has a clamping ring body and an opening located on the clamping ring body, the clamping ring body having a first end and a second end surrounding the opening; wherein the outer end of the extension portion extends into the clamping ring through the opening, and the first end and the second end respectively abut against the second side surface and the third side surface, so that the clamping ring can be removably fixed to the extension portion.

[0007] By providing a wire pressing portion, a protruding portion extending outward from a first side surface of the wire pressing portion, and a clasp removably secured to the protruding portion, the wire pressing device of the present invention not only allows the target wire harness to be held by the wire pressing portion but also allows it to change its direction after extending from the wire pressing portion by passing through the clasp. Because the target wire harness extends in the clasp transversely to its direction of extension beneath the wire pressing portion, it is unlikely to be pulled off after being secured by the wire pressing device.

[0008] In a preferred embodiment of the aforementioned wire crimping device, the outer end portion has an arcuate outer end surface that is concave inwardly toward the outer end portion. By designing the outer end surface of the extension portion that contacts the target wire harness within the clasp into an arcuate shape, the target wire harness can be better fitted with the outer end surface, thereby more securely constraining the target wire harness within the clasp.

[0009] In a preferred technical solution of the aforementioned wire pressing device, a first intersection is formed between the second side surface and the outer end surface, and a second intersection is formed between the third side surface and the outer end surface, and the distance between the first intersection and the first side surface is greater than the distance between the second intersection and the first side surface. With this arrangement, when the target wire harness is subjected to a pull-off force, the direction of the force exerted on the clasp by the wire harness is not aligned with the direction in which the clasp is separated from the protruding portion, thereby effectively preventing the clasp from falling off the protruding portion, thereby ensuring that the target wire harness is secured in the clasp and is not easily pulled off.

[0010] In a preferred technical solution of the above-mentioned wire pressing device, the protruding portion further has at least one boss, each of the bosses extending outward from the second side surface and having an upper surface extending outward from the second side surface and a lower surface extending obliquely downward from the outer edge of the upper surface to the second side surface, wherein the first end portion or the second end portion abuts against the second side surface from above the upper surface. Through the above-mentioned arrangement, since the upper surface is located below the first end portion or the second end portion, the boss on the protruding portion can prevent the retaining ring from falling off the protruding portion, thereby ensuring that the wire harness can be firmly fixed in the retaining ring.

[0011] In a preferred embodiment of the wire crimping device, the upper surface extends outwardly perpendicular to the second side surface or extends obliquely upward from the second side surface. This configuration of the upper surface effectively prevents the clasp from falling off the protruding portion, thereby ensuring that the wire harness is secured in the clasp.

[0012] In a preferred embodiment of the wire crimping device, the protruding portion is provided with multiple rows of spaced-apart bosses extending from the first side surface toward the outer end. By providing multiple rows of bosses on the protruding portion, the retaining ring can be secured at different positions on the lower end portion, thereby enabling the wire crimping device to be used to secure wire harnesses of varying diameters.

[0013] In a preferred embodiment of the wire crimping device, the boss is provided on the third side surface, and the boss on the third side surface is positioned one-to-one opposite the boss on the second side surface, wherein the other of the first end portion or the second end portion abuts the third side surface from above the upper surface. The bosses for securing the clasp are provided on both sides, further ensuring a secure connection between the clasp and the extension, thereby ensuring that the wire harness is securely restrained in the clasp.

[0014] In a preferred technical solution of the above-mentioned wire-pressing device, the wire-pressing portion includes a first wire-pressing portion and a second wire-pressing portion arranged side by side, and an assembly groove located between the first wire-pressing portion and the second wire-pressing portion, the first wire-pressing portion and the second wire-pressing portion both having the wire-pressing surface located on the same side, and the assembly groove is recessed into the wire-pressing portion on one side of the wire-pressing surface. Through the above-mentioned arrangement, the wire-pressing device can simultaneously fix two wire harnesses, and the design of the assembly groove can fit the structure inside the air conditioner electrical box, so that the wire-pressing device can be better fixed inside the electrical box, thereby compressing the wire harnesses.

[0015] In a preferred embodiment of the present invention, the wire-pressing portion includes a first mounting hole on the first wire-pressing portion and a second mounting hole on the second wire-pressing portion. This arrangement allows the wire-pressing device to be secured to the electrical enclosure via screws or rivets, and the provision of the two mounting holes allows the wire-pressing device to be positioned to prevent rotational displacement.

[0016] In order to solve the above-mentioned problems in the prior art, that is, to solve the technical problem in the prior art that the wire-pressing device cannot change the direction of the wire harness, which causes the wire harness to be easily pulled off when subjected to force, the present invention also provides an air conditioner. The air conditioner comprises: an electrical box; a wire harness, the wire harness extending outward from the electrical box; and a wire-pressing device according to any of the above items, the wire-pressing device being installed in the electrical box and its clamp extending to the outside of the electrical box, the wire harness being pressed by the wire-pressing portion of the wire-pressing device and extending through the clamp of the wire-pressing device. Through the above-mentioned arrangement, the wire harness of the air conditioner, such as the power cord, is pressed by the wire-pressing portion of the wire-pressing device and can only pass through the clamp after changing its extension direction, thereby making the wire harness firmly fixed in the electrical box and not easily pulled off due to external force.

[0028] In order to solve the technical problems in the prior art that the wire pressing device cannot change the direction of the wire harness and is easily pulled off when the wire harness is subjected to force, the present invention provides a wire pressing device 1. The wire pressing device 1 includes: a wire pressing portion 11, which has a wire pressing surface 114 configured to press a target wire harness and a first side surface 113 intersecting the wire pressing surface 114; an extension portion 12, which extends vertically outward from the first side surface 113 and has an outer end 121 away from the first side surface 113 and opposite second and third side surfaces 122 and 123; and a clamping ring 13, which has a clamping ring body 131 and an opening 132 located on the clamping ring body 131, the clamping ring body 131 having a first end 1311 and a second end 1312 surrounding the opening 132; wherein the outer end 121 of the extension portion 12 extends into the clamping ring 13 through the opening 132, and the first end 1311 and the second end 1312 respectively abut against the second side surface 122 and the third side surface 123, so that the clamping ring 13 can be removably fixed to the extension portion 12.

[0029] Figure 1 Schematic diagram of the structure of an embodiment of the wire pressing device of the present invention. Figure 1As shown, the wire pressing device 1 includes a wire pressing portion 11, an extension portion 12 and a retaining ring 13, and the surface of the entire wire pressing device 1 is chamfered. In one or more embodiments, the wire pressing portion 11 is roughly rectangular as a whole. Alternatively, the wire pressing portion 11 can be a flat oval or other suitable shape. The wire pressing portion 11 includes an assembly groove 115, a first wire pressing portion 111 and a second wire pressing portion 112 arranged side by side. The first wire pressing portion 111 is located at the relatively right end of the wire pressing portion 11 in the figure, and the second wire pressing portion 112 is located at the relatively left end of the wire pressing portion 11 in the figure. Behind the first wire pressing portion 111 and the second wire pressing portion 112 in the figure (the side perpendicular to the paper surface inward is the back) is a plane, namely the wire pressing surface 114. The wire pressing surface 114 is in direct contact with the wire harness and can press the wire harness. The assembly groove 115 is located between the first wire pressing portion 111 and the second wire pressing portion 112, and the assembly groove 115 is a groove structure that is recessed from the plane where the wire pressing surface 114 is located into the wire pressing portion 11. In an alternative embodiment, the assembly groove 115 can also be eliminated. A reinforcing boss 116 is also provided in front of the wire pressing portion 11 (the side perpendicular to the paper surface is the front). The position of the reinforcing boss 116 is opposite to the assembly groove 115, and is used to strengthen the strength of the wire pressing portion 11 at the position of the assembly groove 115. In an alternative embodiment, the reinforcing boss 116 can also be eliminated. Two mounting holes are provided on the wire pressing portion 11, namely a first mounting hole 1111 provided on the first wire pressing portion 111 and a second mounting hole 1121 provided on the second wire pressing portion 112. In an alternative embodiment, only one mounting hole can be provided on the wire pressing portion 11, or three or more mounting holes can be provided, as long as it can ensure that the wire pressing device 1 is fixed in the electrical box 3 and the wire harness can be compressed. In one or more embodiments, the first mounting hole 1111 and the second mounting hole 1121 are threaded holes, which can cooperate with the threaded parts to fix the wire crimping device 1 to the electrical box 3 through the first mounting hole 1111 and the second mounting hole 1121. In an alternative embodiment, the first mounting hole 1111 and the second mounting hole 1121 can also be countersunk holes or other suitable mounting holes, as long as it is ensured that the wire crimping device 1 can be fixed to the electrical box 3. The surface located relatively below the wire crimping portion 11 in the figure is the first side surface 113 of the wire crimping portion 11. The protruding portion 12 extends vertically downward from the first side surface 113 and is located below the second wire crimping portion 112. In an alternative embodiment, the protruding portion 12 can also be located below the first wire crimping portion 111, or below the middle position between the first wire crimping portion 111 and the second wire crimping portion 112, or at any suitable position below the wire crimping portion.

[0030] Figure 2 1 is a side view of an embodiment of the wire pressing device of the present invention. Figure 2As shown, in one or more embodiments, the extension portion 12 has an outer end portion 121, an opposite second side surface 122, and a third side surface 123. The outer end portion 121 is located below the extension portion 12 as shown in the figure, and has an upwardly concave arc-shaped outer end surface 1211 at the lower end of the outer end portion 121. Alternatively, the outer end surface 1211 of the outer end portion 121 may also be a plane. The second side surface 122 is located on the right side of the outer end portion 121 as shown in the figure, and the third side surface 123 is located on the left side of the outer end portion 121 as shown in the figure. A first intersection line (not marked in the figure) is formed between the second side surface 122 and the outer end surface 1211, and a second intersection line (not marked in the figure) is formed between the third side surface 123 and the outer end surface 1211, and the position of the first intersection line is lower than the position of the second intersection line. Therefore, the outer end surface 1211 is at Figure 2 In the embodiment of the present invention, the second intersection line may be positioned lower than the left intersection line in the arc shape with the right endpoint being lower than the left endpoint. In an alternative embodiment, the position of the second intersection line may be positioned lower relative to the position of the first intersection line, or the position of the first intersection line may be on the same plane as the position of the second intersection line.

[0031] like Figure 1 and Figure 2 As shown, six bosses 124 are provided on the extension portion 12. The six bosses 124 are spaced apart from each other and arranged in two columns and three rows on the second side surface 122 of the extension portion 12. Alternatively, only one boss 124 may be provided on the second side surface 122 of the extension portion 12, or any number of bosses 124 may be provided. In an alternative embodiment, the plurality of bosses 124 may be arranged in four rows from top to bottom or in any other suitable number of rows, and a certain interval is formed between the upper and lower bosses 124 in each row. Providing multiple rows of bosses 124 on the extension portion 12 allows the snap ring 13 to adjust its position fixed on the extension portion 12 and clamp the snap ring 13 on the extension portion 12. As shown in FIG. Figure 2 As shown, the boss 124 is an inverted triangle when viewed from the side, and includes an upper surface 1241 and a lower surface 1242. The upper surface 1241 extends vertically outward (i.e., to the right in the figure) from the second side 122. Alternatively, the upper surface 1241 may also extend obliquely to the upper right from the second side 122, as long as the setting of the boss 124 is conducive to clamping the snap ring 13 on the extension 12. The lower surface 1242 extends obliquely downward from the outer edge of the upper surface 1241 to the second side 122. In one or more embodiments, the boss 124 may also be provided on the third side 123, and the position of the boss 124 on the third side 123 is made one-to-one opposite to the position of the boss 124 on the second side 122, which is more conducive to firmly clamping the snap ring 13 on the extension 12.

[0032] Figure 3 Schematic diagram of the structure of the clamping ring in the embodiment of the wire pressing device of the present invention. Figure 3As shown, the snap ring 13 is generally in the shape of a ring with a notch, and includes a snap ring body 131 and an opening 132. The snap ring body 131 has a first end 1311 and a second end 1312. The opening 132 is formed on the snap ring body 131 and is surrounded by the first end 1311 and the second end 1312 of the snap ring body 131.

[0033] Continue to see Figure 1 The snap ring 13 is removably fixed to the outer end 121 of the extension 12, and the outer end 121 of the extension 12 partially extends into the snap ring 13 through the opening 132 of the snap ring 13. The first end 1311 of the snap ring 13 abuts the second side 122 of the extension 12, while the second end 1312 of the snap ring 13 abuts the third side 123 of the extension 12, thereby clamping the snap ring 13 to the extension 12. Furthermore, the bottom row of bosses on the second side 122 of the extension 12 can abut below the first end 1311 of the snap ring 13, thereby more firmly clamping the snap ring 13 to the extension 12.

[0034] The air conditioner of the present invention (not shown in the figure) has an electrical box 3. Inside the electrical box 3 are a wire pressing device 1 and a power line 2, and the wire pressing device 1 fixes the power line 2 in the electrical box 3.

[0035] Figure 4 This is a partial schematic diagram of the cooperation between the wire pressing device inside the electrical box and the power line in the embodiment of the air conditioner of the present invention. Figure 4As shown, the electrical box 3 includes but is not limited to a housing 31, a wire pressing device 1, a power cord 2, and a ground wire (not shown in the figure). In the housing 31 of the electrical box 3, there is a cavity 32, a protruding structure 33, a wire trough (not shown in the figure), and a threaded hole (not shown in the figure). The protruding structure 33, the wire trough, the threaded hole, the power cord 2, and the ground wire are all arranged in the cavity 32 of the housing 31. In one or more embodiments, the protruding structure 33 is located below the assembly groove 115 of the wire pressing device 1. The setting of the assembly groove 115 on the wire pressing device 1 provides the wire pressing device 1 with space to accommodate the protruding structure 33, so as to ensure that the wire pressing device 1 can better fit the structure inside the electrical box 3, thereby tightly pressing the power cord 2 and the ground wire through the wire pressing portion. Directly below the first mounting hole 1111 on the first wire pressing portion 111 of the wire pressing device 1 in the housing 31, and directly below the second mounting hole 1121 on the second wire pressing portion 112, there are two threaded holes corresponding to the first mounting hole 1111 and the second mounting hole 1121, respectively. Two wire grooves are also provided on the housing 31, directly below the first wire pressing portion 111 and the second wire pressing portion 112 of the wire pressing device 1. The two wire grooves are used to place the power cord 2 and the grounding wire, respectively. When fixing the power cord 2, first place the power cord 2 in the wire groove, then align the first wire pressing portion 111 of the wire pressing device 1 with the power cord 2, and then use bolts (not shown in the figure) to fix the wire pressing device 1 and the electrical box 3 together, and press the power cord 2 under the first wire pressing portion 111. Next, pass the power cord 2 through the clamping ring 13, and force the clamping ring 13 to be clamped to the protruding portion 12 of the wire pressing device 1, so that the power cord 2 is also redirected so that its extension direction in the clamping ring 13 is transverse to its extension direction under the first wire pressing portion 111, as shown in FIG. Figure 4 As shown. This redirected power cord 2 is less susceptible to displacement due to pulling forces. The snap ring 13 can be snapped onto the bottom row of bosses 124. Alternatively, based on the actual diameter of the power cord 2, the snap ring 13 can be snapped onto the boss 124 at the appropriate location to securely hold the power cord 2 between the extension 12 and the snap ring 13. In alternative embodiments, the power cord 2 can also be secured below the second wire pressing portion 112 and passed through the snap ring 13 to change the wiring harness's direction.

[0036] Figure 5 Schematic diagram of the embodiment of the air conditioner of the present invention in which the power cord is fixed in the clamping ring of the wire pressing device. Figure 5 As shown, when the power cord 2 is clamped between the extension 12 and the retaining ring 13 of the wire crimping device 1, the power cord 2 is restrained by the curved outer end surface 1211 of the extension 12 to the lower left of the extension 12 as shown. When the power cord 2 is subjected to a pulling force, the power cord 2 exerts a downward and leftward force on the retaining ring 13. At this time, the extension 12 and the boss 124 thereon exert an upward force on the retaining ring 13 to prevent it from falling off, thereby ensuring that the power cord 2 is firmly fixed between the extension 12 and the retaining ring 13.

However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
