DETAILED DESCRIPTION

[0027] The utility model will be further described below in conjunction with the accompanying drawings.

[0028] like Figure 1 and Figure 2 As shown, the wiring terminal of this embodiment includes a bottom shell 1, an upper cover 2 and a wiring assembly 3. The upper cover 2 is snap-connected with the bottom shell 1, and both are insulators. The wiring assembly 3 is arranged in the bottom shell 1. The wiring assembly 3 includes an elastic member 31 and a pressure head 32. The elastic member 31 is arranged between the upper cover 2 and the pressure head 32. When the upper cover 2 is connected to the bottom shell 1, the upper cover 2 presses the elastic member 31, and the elastic member 31 causes the pressure head 32 to press the wire 100 inserted into the bottom shell 1. In this embodiment, the elastic member 31 is a spring.

[0029] The bottom shell 1 and the upper cover 2 are assembled in the form of a snap connection, and the bottom shell 1 and the upper cover 2 can be easily disassembled and connected without the aid of tools. Before the bottom shell 1 and the upper cover 2 are connected, the elastic member 31 does not press the pressure head 32, so that the wire 100 is easily inserted into the bottom shell 1. When the wire 100 is inserted into place, the upper cover 2 is connected to the bottom shell 1, and the upper cover 2 compresses the elastic member 31 by pressing the elastic member 31. The elastic force of the elastic member 31 causes the pressure head 32 to press the wire 100 between the pressure head 32 and the bottom shell 1, thereby completing the fixation of the wire 100. The operation is simple, and the connection of the wire 100 is stable and not easy to loosen.

[0030] The wiring terminals of this embodiment can be used in the production process of the air conditioner and in the on-site installation process of the air conditioner. When it is necessary to connect various power lines, the wiring terminals of this embodiment can be used to quickly and conveniently install and fix the wires 100, thereby improving the work efficiency of the installers and preventing the wires 100 from loosening, thereby avoiding safety accidents.

[0031] like Figures 2 to 5As shown, further, the wiring assembly 3 further includes a limit frame 33 and a pressing member 34, the limit frame 33 is connected to the bottom shell 1, and one side of the pressing member 34 is connected to the elastic member 31, as shown in FIG. Figure 6 As shown, the limit frame 33 is a frame structure, and the upper cover 2 can pass through the limit frame 33 and press the pressing member 34, so that the pressing member 34 is separated from the limit frame 33 and compresses the elastic member 31. The pressing member 34 in this embodiment is in the shape of a plate, which can provide good and stable support for one end of the elastic member 31 to prevent the elastic member 31 from being significantly bent during the expansion and contraction process. The limit frame 33 provides support and limitation for the pressing member 34, and the elastic member 31 still has a certain amount of compression even before the wire 100 is inserted into the bottom shell 1. When the wire 100 is inserted and before the upper cover 2 is connected to the bottom shell 1, the pressure head 32 can still apply a little pressure to the wire 100, and before the wire 100 is pressed by the pressure head 32, it has a certain positioning effect on the wire 100, reduces the probability of displacement of the wire 100, and ensures the fixing effect of the pressure head 32 on the wire 100.

[0032] like Figures 2 to 5 As shown, the wiring assembly 3 further includes a guide member 35, which is slidably disposed in the bottom shell 1, and the pressure head 32 is disposed on the guide member 35. By disposing the pressure head 32 on the guide member 35, the movement trajectory of the pressure head 32 can be made more stable, and the force direction of the elastic member 31 can also be kept stable, thereby preventing the elastic member 31 from bending and deforming.

[0033] like Figure 2 As shown, specifically, the pressure head 32 includes a main body 321 and positioning parts 322 arranged at both ends of the main body 321. The guide member 35 is provided with a positioning hole 351 for the positioning part 322 to be inserted, so that the pressure head 32 can rotate on the guide member 35. When the wire 100 is inserted into the bottom shell 1, the wire 100 will contact and rub against the pressure head 32. Configuring the pressure head 32 to be rotatable can reduce the resistance when the wire 100 is inserted, which is conducive to the insertion of the wire 100 under the pressure head 32.

[0034] like Figure 2 and Figure 4 As shown, the guide member 35 includes a shell 352 and a guide rib 353 disposed on the surface of the shell 352, the positioning hole 351 is opened between the two guide ribs 353, and the bottom shell 1 is provided with a guide groove 12 for accommodating the guide rib 353. When the pressure head 32 is installed on the guide member 35, the positioning parts 322 at both ends are located between the two guide ribs 353, and the positioning parts 322 will not directly contact the bottom shell 1, so as to avoid friction between the two.

[0035] like Figures 3 to 5As shown, the bottom shell 1 is provided with a groove 13, and the groove 13 is arranged opposite to the pressing head 32, and the pressing head 32 can be pressed into the groove 13. By providing the groove 13, when the pressing head 32 presses the wire 100, the wire 100 will be pressed into the groove 13 and bend to a certain extent, so that the wire 100 is more difficult to be pulled out after being pressed by the pressing head 32, and has a better fixing effect.

[0036] like Figures 3 to 5 As shown, the main body 321 is cylindrical, and the cross section of the groove 13 is arched to match the shape of the main body 321. The cylindrical main body 321 is easy to roll, so that the resistance when the wire 100 is inserted is smaller. The shape of the groove 13 matches the shape of the main body 321, so that the pressure of the pressure head 32 can make the wire 100 fit more easily in the groove 13, thereby improving the fixing effect. In this embodiment, the surface of the groove 13 is roughened to increase the friction between it and the wire 100, making it more difficult for the wire 100 to be pulled out.

[0037] like Figures 2 to 5 As shown, the wiring assembly 3 further includes a connector 36, which is disposed between the pressure head 32 and the pressing member 34. The connector 36 is provided with a positioning groove 361 for the main body 321 to be inserted into, and one end of the elastic member 31 away from the pressing member 34 is connected to the connector 36. Since the main body 321 is a cylinder, it is difficult for the elastic member 31 to be directly and stably fixed on the main body 321. By providing the connector 36, a stable fixed position can be provided for the elastic member 31. In addition, the shape of the positioning groove 361 matches the shape of the main body 321, so that the connector 36 does not hinder the rotation of the main body 321.

[0038] like Figure 1 and Figure 2 As shown, both ends of the bottom shell 1 are provided with through holes 11 for inserting the wires 100. The elastic member 31, the pressure head 32, the pressing member 34 and the connecting member 36 in the wiring assembly 3 are all conductors, so that the two wires 100 can be connected.

[0039] like Figure 1 and Figure 2 As shown, the upper cover 2 is provided with a hook 21, and the bottom shell 1 is provided with a slot 14 and a recessed area 15 for the hook 21 to be inserted into. The bottom shell 1 and the upper cover 2 are detachably connected through the cooperation of the hook 21 and the slot 14. When the bottom shell 1 and the upper cover 2 need to be connected, the upper cover 2 only needs to be pressed, and the hook 21 can be inserted into the slot 14. The recessed area 15 can provide a certain operating space for fingers, so that the staff can use their fingers to pry open the upper cover 2, thereby realizing the detachment of the hook 21.

[0040] Although the present invention has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there is no structural conflict.
