The present embodiment provides a power connector, and fig. 1 is a schematic structural diagram of the power connector provided in the present embodiment, where the power connector includes a socket module 2 and a plug module 1. The surface of the housing of each socket module 2 is provided with a plurality of convex contacts, the plurality of convex contacts are arranged according to a preset coding mode, and each socket module 2 is provided with a fixed and unique coding value; the shell surface of each plug module 1 is provided with a contact switch array corresponding to the plurality of convex contacts, the original state of a switch in the contact switch array is in an open state, and when the plug module 1 is plugged into the socket module 2, the switch in the contact switch array is extruded by the plurality of convex contacts, so that the switch state in the contact switch array corresponding to the plurality of convex contacts is changed, namely, the original open state is changed into a closed state; in addition, the plug module 1 further includes a switch state monitoring unit and a processor, where the switch state monitoring unit is electrically connected to the contact switch array, the processor is electrically connected to the state monitoring unit, and monitors the state of each contact switch in the contact switch array through the on and off states of the switch state monitoring unit, and sends the monitoring result of the switch monitoring unit to the processor, so as to obtain the identification information of the socket module 2.

Further, in the above power connector, the plurality of protruding contacts on the surface of the housing of the socket module 2 are in a cambered surface shape and are located at any two orientations of the socket module 2, where the protruding contacts in one orientation are used to represent the type of the socket module 2, such as a civil socket, an industrial socket, a waterproof socket, a power socket, and the like, and because each socket has different applications in actual processes, its rated power and whether there is a grounding arrangement are different, so in order to ensure the electrical safety of the device, each device preferably selects the type of the socket module 2 corresponding to the socket module, and cannot be mutually mixed, thereby increasing the potential safety hazard. In addition, the male contacts in one orientation are used to characterize the numbering of the jack module 2 described above. The arrangement modes of the plurality of convex contacts in each socket module 2 are different, so that the serial numbers of each socket module 2 are different, and the uniqueness of the identification information of each socket module 2 is ensured.

In order to ensure that the state of the contact switch array in the plug module 1 can be changed by the plurality of protruding contacts in the socket module 2 when the plug module 1 is plugged into the socket module 2, the orientation of the contact switch array in the plug module 1 is consistent with the orientation of the plurality of protruding contacts in the socket module 2, for example, the protruding contacts representing the type of the socket module 2 are located at the position of the upper left corner of the intersecting surface of the socket module 2 and the plug module 1 in a top view, the protruding contacts representing the number of the socket module 2 are located at the position of the upper right corner of the intersecting surface of the socket module 2 and the plug module 1 in a top view, and the contact switch array corresponding to the type of the representing socket module 2 is located at the position of the upper left corner of the intersecting surface of the socket module 2 and the plug module 1 in a bottom view, so as to ensure that the state of the contact switch array can be changed by the protruding contacts.

In an alternative embodiment, the plug module 1 and the socket module 2 are mechanically connected.

Specifically, the plug module 1 and the socket module 2 are connected by plugging, and when the plug module 1 and the socket module 2 are connected and/or separated, the moving direction of the plug module 1 and the socket module 2 is a reciprocating linear motion, and the plug module can be detached without twisting and/or rotating, and only a small working space is required.

In an alternative embodiment, the switch state monitoring unit comprises a plurality of monitoring circuits, each of which operates independently of the other and is connected to the same processor.

Specifically, the resistors inside the switch state monitoring unit are connected to different input ports of the same processor, when the contact switch in one monitoring circuit is changed to be in a closed state by the convex contact of the socket module 2, the circuit is conducted, the input ports of the processor connected with the monitoring circuit can detect an electric signal, while when the contact switch in other monitoring circuits is not changed to be in an open state by the convex contact of the socket module 2, the circuit is not conducted, the input ports of the processor connected with the monitoring circuits can not detect the electric signal, and because the contact switch of each monitoring circuit is positioned above each branch, the on and off of each monitoring circuit can not be influenced by other monitoring circuits. Therefore, the plurality of convex contacts of the socket module 2 are arranged in different manners, so that when the plug module 1 is plugged into the socket module 2, the on-off arrangement of each monitoring circuit in the switch state monitoring unit is different, and the input port of the processor receives the electric signal of the predictive coding manner of the socket module 2.

Fig. 2 is a method for automatically acquiring a communication address by a power connector according to the present embodiment. The method may be performed in the power connector described above. As shown in fig. 2, the process includes the steps of:

step S201, a plurality of pieces of convex contact information arranged according to a preset coding mode and arranged on the surface of a shell of the socket are acquired and recorded as socket identification information.

Step S202, when a plug is plugged into the socket, the plurality of contact switches in the contact switch array 11 of the plug are changed in state by the plurality of convex contacts, and state information of the contact switch array 11 of the plug is acquired and recorded as switch state information.

In step S203, the processor obtains the socket identification information according to the switch status information.

In step S201, the socket housing has a certain number of protruding contacts on its surface, where the protruding contacts are arranged according to a preset coding manner, and the arrangement manner of the protruding contacts on each socket housing surface is different, so that the current socket identification information can be obtained according to the arrangement manner of the protruding contacts.

According to the method for automatically acquiring the communication address by the power connector, firstly, the shell surface of each socket is provided with a plurality of convex contacts, each convex contact is arranged according to a preset coding mode, and the arrangement modes of the convex contacts in each socket are different, so that each socket contains unique socket identification information; when the plug is plugged into the socket, the arrangement mode of the convex contacts of the socket can be obtained through the on-off states of the contact switch array 11 of the plug, the contact switch of the contact switch array 11 of the plug is closed at the place with the convex contacts, and the on-off state information of the contact switch array 11 of the plug is sent to the processor, so that the processor receives the switch state information with the preset arrangement mode, the socket identification information is obtained, and the preset information of the socket also represents the current communication address of the equipment. According to the method, on one hand, the plug obtains the socket identification information in a plugging mode, and the mode of obtaining the socket identification information is simplified. On the other hand, the socket identification information is characterized by adopting a preset coding mode, so that the socket identification information is ensured to be different from each other, and the socket identification information acquired by each plug is also different from each other after a plurality of plugs are respectively plugged into corresponding sockets, thereby avoiding the phenomenon of address repetition. In this embodiment, the communication address of the device is not required to be acquired by communicating with a worker, but only the preset socket identification information is required to be used as the communication address of the plug connection device, so that a great amount of manual operation is omitted, the phenomenon of repeated setting of the device address is avoided, and the work of acquiring the communication address is simplified and facilitated.

In this embodiment, the socket identification information includes two dimensions of information, where the first dimension of information characterizes a type of the socket identification information, and the second dimension of information characterizes a number of the socket identification information.

Specifically, the type of socket identification information includes, but is not limited to, at least one of: civil socket type information, industrial socket type information, waterproof socket type information, and power socket type information. The number information of the socket identification information is also plural and different.

The coding scheme in this embodiment may perform 0/1 coding according to the presence or absence of a protruding contact, where the position where the protruding contact is present is denoted as 1 and the position where the protruding point is absent is denoted as 0. Because the socket types among different sockets are repeatable, the number of bits which can adopt a 0/1 coding mode comprises four bits but is not limited to four bits, for example, the socket identification information of the civil socket type is 0001, the identification information of the industrial socket type is 0010, the socket identification information of the waterproof socket type is 0101, and the socket identification information of the power socket type is 0100. For socket numbers that may have hundreds and are not repeatable, the number of bits that may be used with a 0/1 code includes ten bits, but is not limited to ten bits, e.g., the first socket has a code of 0000000001 and the second socket has a code of 0000000010, ….

In addition, to ensure that the plurality of contact switches in the contact switch array 11 of the plug can be changed in state by the plurality of male contacts, the dimension of the switch state information coincides with the dimension of the receptacle identification information.

In this embodiment, the processor obtaining the socket identification information according to the switch state information includes:

and acquiring an effective signal in the switch state information, and determining the socket identification information according to the effective signal by a processor.

Specifically, when the plug and the receptacle are in the separated state, all the contact switch states in the contact switch array 11 of the plug are in the open state, the switch state information in the first dimension is 0000, and the switch state information in the second dimension is 0000000000. When the plug is plugged into the socket, the states of the plurality of contact switches in the contact switch array 11 of the plug are changed, the positions of the states of the plurality of contact switches are changed by the convex contacts on the surface of the socket, the corresponding state values are changed from 0 to 1, at the moment, the switch state information of the first dimension and the switch state information of the second dimension are changed along with the corresponding socket identification information, the switch state information of the plug represents the corresponding socket identification information, for example, when the plug is plugged into a tenth socket of a civil socket type, the switch state information of the first dimension of the plug is 0001, and the switch state information of the second dimension of the plug is 0000001010. At this time, the signal representing the current position of the position, marked as 1, of the switch state information of the plug is a valid signal, otherwise, is an invalid signal, and the processor determines the socket identification information by performing correlation calculation with the valid signal and the invalid signal in the switch state information of the plug.

Fig. 3 is a system for automatically acquiring a communication address by a power connector according to the present embodiment. As illustrated in fig. 3, the flow includes the following elements:

a reading unit 4, configured to obtain a plurality of pieces of convex contact information arranged according to a preset coding manner and set on a surface of a housing of the socket, and record the pieces of convex contact information as socket preset information;

and the processing unit 6 is used for acquiring the socket preset information according to the switch state information.

Specifically, firstly, the reading unit 4 is used for obtaining the preset coding information of the socket, then the monitoring unit 5 is used for monitoring the on and off of the circuit, the plug is used for obtaining the switch state information consistent with the socket identification information, and finally the processing unit 6 is used for obtaining the arrangement of the effective signal and the ineffective signal of the switch state information through the switch state information, obtaining the preset information of the final socket, and the preset information of the socket also represents the current communication address of the equipment.

The steps are not strictly limited in order and may be performed in other orders, unless explicitly stated herein.
