Description
技术领域 technical field
本实用新型涉及电机领域，尤其涉及一种防爆电机用接线装置。 The utility model relates to the field of motors, in particular to a wiring device for an explosion-proof motor.
背景技术 Background technique
由于防爆电机用在有危险性气体的环境，所以防爆电机的结构设计有很严格的要求。现有的防爆电动机的接线装置包括绝缘层和接线柱，接线柱的外圆压制有绝缘层，绝缘层通过螺栓将整个接线装置固定在出线盒机座安装孔内，由于螺栓连接处为台阶状的绝缘层，为了考虑连接强度，接线柱外圆的绝缘层不能太厚，往往压制绝缘层的外圆会小于接线柱电机内部的连接处的最大圆周尺寸，从而将接线柱先固定在出线盒内，然后再在电机内部将电机内部的出线电缆和接线柱连接在一起，由于电机内部的空间非常有限，在接线过程中操作困难，很容易造成接线松动现象。 Since the explosion-proof motor is used in an environment with dangerous gases, the structural design of the explosion-proof motor has very strict requirements. The wiring device of the existing explosion-proof motor includes an insulating layer and a terminal. The outer circle of the terminal is pressed with an insulating layer. Insulation layer, in order to consider the connection strength, the insulation layer of the outer circle of the terminal should not be too thick, often the outer circle of the pressed insulation layer will be smaller than the maximum circumference of the connection inside the terminal motor, so that the terminal is first fixed on the outlet box Inside the motor, and then connect the outgoing cables inside the motor with the terminals. Since the space inside the motor is very limited, it is difficult to operate during the wiring process, and it is easy to cause loose wiring.
实用新型内容 Utility model content
本实用新型的目的是在于克服以上缺陷提供一种操作简单连接牢靠的防爆电机用接线装置。 The purpose of this utility model is to overcome the above defects and provide a wiring device for explosion-proof motors with simple operation and reliable connection.
本实用新型的技术方案是：一种防爆电机用接线装置，其包括接线柱、绝缘层，接线柱的外圆设有绝缘层，还包括隔爆套，所述隔爆套为钢制件，隔爆套设置在绝缘层与出线盒的机座安装孔之间，隔爆套与绝缘层固定成一个整体，所述机座安装孔的直径大于接线柱在电机内部的连接处的最大圆周尺寸。 The technical scheme of the utility model is: a wiring device for an explosion-proof motor, which includes a terminal post and an insulating layer. The outer circle of the terminal post is provided with an insulating layer, and also includes a flameproof sleeve. The explosion-proof sleeve is arranged between the insulating layer and the mounting hole of the frame of the outlet box, and the flame-proof sleeve and the insulating layer are fixed as a whole. The diameter of the mounting hole of the frame is larger than the maximum circumference size of the connection of the terminal in the motor .
为了使隔爆套与绝缘层连接紧固，所述隔爆套内孔为从电机内部至外部由大至小的锥孔。 In order to fasten the connection between the flame-proof sleeve and the insulating layer, the inner hole of the flame-proof sleeve is a tapered hole from the inside to the outside of the motor.
本实用新型的有益效果是：本装置增加了隔爆套后，机座安装孔可进行加大，安装孔直径大于接线柱在电机内部的连接处的最大圆周尺寸，从而可以将电缆从机座安装孔拉出后，再与接线柱连接，然后在将接线柱固定在机座安装孔内，此外，采用钢制隔爆套还可以增强接线装置固定位置的强度，整个装置简单，连接牢靠。 The beneficial effects of the utility model are: after the flameproof sleeve is added to the device, the installation hole of the machine base can be enlarged, and the diameter of the installation hole is larger than the maximum circumference size of the connection of the terminal in the motor, so that the cable can be pulled from the machine base After the installation hole is pulled out, it is connected with the terminal, and then the terminal is fixed in the installation hole of the machine base. In addition, the steel flameproof sleeve can also enhance the strength of the fixed position of the wiring device. The whole device is simple and the connection is firm.
