Detailed Description
The invention will be further explained with reference to the drawings.
According to a first aspect of the present invention, as shown in fig. 1, the present invention provides a connection structure of an electric box and a load and an air conditioner, comprising an insulating housing 1 and at least one metal connection sheet 2 disposed inside the insulating housing 1 and electrically connected to a circuit board (not shown) in the electric box.
A load access means (not shown) is provided on the insulating housing 1 for accessing a load. One end of the load access means extends into the insulating housing 1 and abuts a first end (i.e. the top end) of the metal connecting piece 2, and the other end of the load access means is connected to a load (not shown). Because one end of the load access device is directly butted with the first end of the metal connecting sheet 2, the condition of connection through a connecting line in the original process is eliminated, and the condition of wrong connection or reverse connection of the connecting line is fundamentally avoided, so that the service life and the reliability of the load and related parts are prolonged, and the using effect of the load and related parts is improved.
Further, a first reverse plugging prevention structure 12 is arranged on the insulating housing 1, the first reverse plugging prevention structure 12 is connected with the load access device, and the first reverse plugging prevention structure 12 is used for connecting the load access device with the insulating housing 1 according to a specified mode.
Specifically, the first anti-reverse-insertion structure 12 includes a clamping portion 121 disposed on a side portion of the insulating housing 1, and the clamping portion 121 is connected to a buckling portion on the load access device in a one-to-one corresponding manner.
Therefore, by providing the first anti-reverse-plugging structure 12, the load access device can only be connected with the insulating housing 1 in a specified manner (for example, in a specified access direction), otherwise, the load access device cannot be connected with the insulating housing 1 and cannot be abutted against the metal connecting sheet 2, so that the load phase sequence can be consistent with the phase sequence of the circuit board.
The number of the first anti-reverse insertion structures 12 may be one or more, and the present invention is not limited thereto.
In some embodiments, the first end of the insulating housing 1 is provided with a slot 11, and one end of the load access device abuts against the first end of the metal connecting piece 2 through the slot 11. As shown in fig. 3, the slot 11 is located at the top end of the insulating housing 1, and one end of the load access device can extend into the slot 11 and abut against the top end of the metal connecting piece 2.
As shown in fig. 2, the top end of the metal connecting plate 2 is used for interfacing with a load access device, and the bottom end thereof is provided with a pin 21, and the pin 21 of the metal connecting plate 2 is extended from the second end of the insulating housing 1 and then is connected with the circuit board 3 by welding. In order to ensure that the first end of the pin 21 of the metal connecting sheet 2 can be accurately butted with the load access device after being connected with the circuit board, a limit distance is reserved between the slot 11 and the first end of the metal connecting sheet 2, namely the upper end surface of the metal connecting sheet 2 is lower than the inner side end surface of the insulating shell 1 by a certain distance, so that the load access device can be butted with the metal connecting sheet 2 after extending into the slot 11 by a certain distance, and the phenomenon that the first end of the metal connecting sheet 2 is contacted with the inner wall of the insulating shell 1 after the pin 21 of the metal connecting sheet 2 is connected with the circuit board is avoided.
In some preferred embodiments, the second end of the insulating housing 1 is further provided with a second anti-reverse-plugging structure 13, the second anti-reverse-plugging structure 13 is connected with the circuit board 3, and the second anti-reverse-plugging structure 13 is used for connecting the insulating housing 1 with the circuit board 3 according to a specified mode.
Specifically, the second anti-reverse-insertion structure 13 is a boss, and the boss is inserted into and connected with the groove on the circuit board 3. As shown in fig. 3, the second anti-reverse-plugging structure 13 may be disposed at the bottom of the insulating housing 1 near the edge, and since a certain space needs to be reserved for the groove on the circuit, the second anti-reverse-plugging structure 13 is disposed at the edge, so that interference with other components on the circuit can be avoided as much as possible.
The number of the second anti-reverse insertion structures 13 may be one or more, and the present invention is not limited thereto.
Preferably, the metal connecting sheet 2 is a copper insert sheet, and an existing copper insert sheet can be adopted. Since the metal connecting sheet 2 itself has no linearity, there is no direction requirement for the connection with the circuit board. But since the insulating housing 1 is provided outside thereof, the uniformity of the wire sequence is ensured by the insulating housing 1. That is, the insulation housing 1 and the metal connecting sheet 2 can be connected with the circuit board 3 in a fixed manner through the second anti-reverse-insertion structure 13 at the bottom of the insulation housing 1, otherwise, the insulation housing 1 cannot be installed in place, and therefore, the installation manner of the insulation housing 1 is mechanically guaranteed to be the expected installation manner only without manual inspection. Furthermore, the first anti-reverse-plugging structure 12 on the side of the insulating shell 1 can ensure that the load access device is connected with the insulating shell 1 and connected with the metal connecting sheet 2 in a predetermined mode, and similarly, if the installation direction of the load access device is not correct, the load access device cannot be connected with the insulating shell 1, so that the load access device can only be installed in a desired mode, and therefore, the installation of each component is completed according to the specified direction, so that the load phase sequence can be ensured to be consistent with the circuit board phase sequence.
In addition, in the installation process, the installation direction does not need to be manually checked, and the condition of non-installation can be immediately caused as long as the installation direction is not right, so that the labor intensity of operators is reduced, and the working efficiency is improved.
Further, insulating casing 1 is inside hollow injection molding, and metal connecting piece 2 does not link to each other with insulating casing 1's lateral wall promptly, consequently can guarantee insulating properties on the basis of the whole protection of metal connecting piece 2.
The bottom of insulating casing 1 has seted up the cell body, and metal connecting piece 2's pin stretches out from the cell body to weld with corresponding pad on the circuit board, thereby make metal connecting piece 2 and circuit board fixed completely, and need not to change the circuit board and to connect terminal structure. The insulating shell 1 is connected with the circuit board in an inserting fit mode through the second anti-reverse-inserting structure 13, and the boss is tightly matched with the groove in the circuit board 3, so that the insulating shell 1 and the circuit board are completely fixed. The first reverse plug-in prevention structure 12 on the insulating shell 1 can ensure that the insulating shell 1 and the load access device are fixed with each other, so that the circuit board, the metal connecting sheet 2, the insulating shell 1, the load access device and the load are completely and fixedly connected to ensure the normal conduction of the circuit.
According to a second aspect of the present invention, there is provided an air conditioner including the above-described connection structure of the electric appliance box and the load.
While the invention has been described with reference to a preferred embodiment, various modifications may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In particular, the technical features mentioned in the embodiments can be combined in any way as long as there is no structural conflict. It is intended that the invention not be limited to the particular embodiments disclosed, but that the invention will include all embodiments falling within the scope of the appended claims.
