摘要： The present invention relates to the field of electrical technology, and in particular, an electrical device. The electrical device provided by the present invention comprises a box, an external device and an external handle; the external device is fixed outside the box; the external handle is provided on the external device; and the external handle is used for carrying the electrical device. By providing the external handle on the external device, the external handle does not occupy the space of the box, and the occupation area of the box after the mounting of the external handle is reduced, such that the box can be made smaller, and the cost of the box is reduced, thereby reducing the cost of the whole machine, and improving the market competitiveness of the electrical device.

摘要： The present invention relates to the technical field of electrical technologies, and in particular to electrical equipment. The electrical equipment provided by the present invention comprises a box body, a device, and a sealing member having both an electromagnetic shielding function and a sealing function. The device is detachably fixed on the box body, the sealing member is disposed between the box body and the device, and the base surface of the device can be attached to the installation surface of the box body, such that the sealing member can ensure the sealing installation of the box body and the device, and can also enable the base surface of the device to be closely attached to the installation surface of the box body to ensure the electromagnetic shielding function of conductive contact between the box body and the device. In the case of ensuring the sealing performance by using the sealing member, the electrical equipment does not need to add additional conductive contact parts between the box body and the device to ensure the electromagnetic shielding function of the conductive contact between the box body and the device, thereby reducing the process difficulty, saving cost, causing no short circuit inside the box body, and ensuring the stable operation of the electrical equipment.

摘要： Disclosed are a case and a mounting piece thereof, and an electrical device. The mounting piece of the case comprises a case connecting outer wall and a cover plate connecting outer wall, wherein the case connecting outer wall is provided with a through hole allowing for a case fixing part on an inner wall of a case body to pass through. The provision of the through hole in the mounting piece of the case to allow the case fixing part on the inner wall of the case body to pass through enables the case fixing part to be directly fixed to the case body, without providing a hole in the case body, such that waterproofing can be achieved without providing a seal between the mounting piece and the case body, thus effectively reducing installation materials and improving installation efficiency; in addition, the case body and the mounting piece can be fixed at the interior of the case body, thereby preventing the exposure of case fixing parts and case connecting parts connected to the case fixing parts, thus improving the appearance of the whole case. Compared with the prior art, the provision of the through hole and the absence of a groove for accommodating the seal simplify the processing, effectively improve processing efficiency and reduce the processing cost.

摘要： A plug for a connector and the connector are provided. The plug includes an elastic main body, the elastic main body is provided with multiple through holes for cables to pass through; the plug includes a support body, the support body includes a first support body embedded in a middle part of the elastic main body, the through holes are provided around the first support body, and the support body has a hardness greater than that of the elastic main body. In this application, due to the elastic material characteristics of the elastic main body, when the claw members are squeezed by the first nut to contract and then the claw members force the plug tightly from periphery, the plug can generate a certain deformation to be tightly clamped by the claw members and press the cables from the outside to the middle part. Besides, because the middle part is provided with the support body having a greater hardness, which is equivalent to a middle skeleton of the plug, the problem that the elastic main body easily slacks due to insufficient support in the middle part of can be solved, and thereby it is ensured that the cables are clamped well during the clamping process.

摘要： Disclosed in the present invention are a PV terminal assembly and an electrical device. The PV terminal assembly comprises a mounting frame and at least one PV terminal; the mounting frame is provided with mounting positions used for fixing PV terminals, and there are at least two mounting positions. In the PV terminal assembly disclosed in the present invention, the mounting frame is provided with mounting positions used for fixing PV terminals, and there are at least two mounting positions, so that at least two PV terminals can be integrated on the mounting frame. The number of PV terminals on the whole PV terminal assembly can be adjusted by adjusting the number of PV terminals on the mounting frame; thus, the expandability and compatibility are improved, the whole electrical device can be compatible with a variety of input configurations, and the development efficiency is improved. Moreover, the space occupied by all the PV terminals can be reduced, thereby reducing the size of the whole electrical device; installation of the PV terminals is also simplified, thereby improving the installation efficiency.
