The above is a description of a specific connection manner of the housing 201 and the power compartment 100, and the relationship between the first electrical plug 101 and the second electrical plug 203 and the housing 201 will be described below, and the first electrical plug 101 is flexibly or rigidly connected to the power compartment 100. The flexible connection is understood to mean that the first electrical plug 101 is in communication connection with the power compartment 100 through a wire in the middle except for fixed connection, the position of the first electrical plug 101 can be adjusted through the wire, and the longer the guiding distance between the power compartment 100 and the first electrical plug 101 is, the more flexible the adjustment of the relative position between the two is. While a rigid connection is in contrast to a flexible connection, the first electrical plug 101 is directly fixed to the power pod 100, and the relative position between the two cannot be adjusted.
Likewise, the second electrical plug 203 is flexibly or rigidly connected to the housing 201. The flexible connection is understood to mean that the second electrical plug 203 is in communication connection with the housing 201 through a wire in the middle except for the fixed connection, the position of the second electrical plug 203 can be adjusted through the wire, and the relative position between the housing 201 and the second electrical plug 203 is more flexibly adjusted as the guiding distance between the housing 201 and the second electrical plug 203 is longer. Whereas a rigid connection is in contrast to a flexible connection, the second electrical plug 203 is directly fixed to the housing 201, the relative position between the two being not adjustable.
For example: when the first electrical plug 101 is flexibly connected with the power compartment 100 and the second electrical plug 203 is flexibly connected with the housing 201, the power compartment 100 is fixedly connected with the housing 201 before or after the first electrical plug 101 and the second electrical plug 203 are butted. Since the power pod 100 and the housing 201 are connected through the screw thread, there are two cases, that is, there is relative rotational movement between the first power pod 100 and the housing 201, and there is no relative rotational movement between the second power pod 100 and the housing 201. In particular, in the first case, in order to prevent the wires between the first electrical plug 101 and the power pod 100 and between the second electrical plug 203 and the housing 201 from being twisted off, the mating of the first electrical plug 101 and the second electrical plug 203 is after the power pod 100 and the housing 201 are fixedly connected.
Alternatively, when the first electrical plug 101 is rigidly connected to the power pod 100 and the second electrical plug 203 is rigidly connected to the housing 201, the power pod 100 and the housing 201 are simultaneously mated when the first electrical plug 101 and the second electrical plug 203 are mated. Since the power pod 100 and the housing 201 are connected through the screw thread, there are two cases, that is, there is relative rotational movement between the first power pod 100 and the housing 201, and there is no relative rotational movement between the second power pod 100 and the housing 201. In particular, in the first case, in order to prevent the first electrical plug 101 and the second electrical plug 203 from being twisted off, the first electrical plug 101 is rotatably provided on the power compartment 100, and the first electrical plug 101 and the power compartment 100 are electrically connected by a brush; the second electric plug 203 is rotatably arranged on the housing 201, the second electric plug 203 is electrically connected with the housing 201 through a brush, and when the power compartment 100 and the housing 201 perform relative rotation movement, the first electric plug 101 and the second electric plug 203 synchronously rotate without influencing the normal use of the first electric plug 101 and the second electric plug 203.
Alternatively, when the first electrical plug 101 is flexibly connected to the power pod 100 and the second electrical plug 203 is rigidly connected to the housing 201, the power pod 100 is fixedly connected to the housing 201 before or after the first electrical plug 101 and the second electrical plug 203 are mated. Since the power pod 100 and the housing 201 are connected through the screw thread, there are two cases, that is, there is relative rotational movement between the first power pod 100 and the housing 201, and there is no relative rotational movement between the second power pod 100 and the housing 201. In particular, in the first case, in order to prevent the wires between the first electrical plug 101 and the power pod 100 and between the second electrical plug 203 and the housing 201 from being twisted off, the mating of the first electrical plug 101 and the second electrical plug 203 is after the power pod 100 and the housing 201 are fixedly connected.
Alternatively, when the first electrical plug 101 is rigidly connected to the power pod 100 and the second electrical plug 203 is flexibly connected to the housing 201, the power pod 100 is fixedly connected to the housing 201 before or after the first electrical plug 101 and the second electrical plug 203 are mated. Since the power pod 100 and the housing 201 are connected through the screw thread, there are two cases, that is, there is relative rotational movement between the first power pod 100 and the housing 201, and there is no relative rotational movement between the second power pod 100 and the housing 201. In particular, in the first case, in order to prevent the wires between the first electrical plug 101 and the power pod 100 and between the second electrical plug 203 and the housing 201 from being twisted off, the mating of the first electrical plug 101 and the second electrical plug 203 is after the power pod 100 and the housing 201 are fixedly connected.
Since the first electrical plug 101 and the second electrical plug 203 are used to realize the communication connection between the lower body 200 and the power compartment 100, it is preferable that the first electrical plug 101 and the second electrical plug 203 are fast plugs, preferably D-SUB standard electrical plug types, as long as the above-mentioned objects can be achieved, so that the connection reliability and the transmittable data types can be improved.
