The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.

In consideration of the prior art, the existing electrical connection module can basically realize the combination and connection mode of only limited connection points, and has small adjustable freedom degree. If a connection is to be replaced, a new electrical connection module is often replaced or manufactured, resulting in inefficiencies and increased costs.

Accordingly, the embodiment of the invention provides an electrical connection module, which can realize the function of free electrical connection and has high adjustability. The following is described by way of example.

Example 1

Referring to fig. 1, an embodiment of the present invention provides an electrical connection module, which is used to implement a function of free electrical connection, and may be used in power supply and distribution, signal switching, routing control, and the like. And the routing control of the bus matrix switch is realized. The module specifically comprises:

4m buses and 4n access points; the relay array consists of 4n relays; the access points are respectively connected to the bus through corresponding relays; the 4 m-th bus is equivalent to a (4m-3) -th bus, and the (4m-1) -th bus is equivalent to a (4m-2) -th bus; the m is a natural number, and the n is a natural number. That is, m and n can be arbitrarily chosen in the range of natural numbers and then combined, and there are various combinations of access points, buses, and relays that are actually formed. Among the plurality of buses, this rule of equivalence of the 4 m-th bus and the (4m-3) th bus, the (4m-1) th bus and the (4m-2) th bus is also followed. Through the relay, the access point can carry out corresponding switching on, switching off and switching on the multipath circuit through the relay, thereby achieving the purpose of being connected to a corresponding bus or a bus combination, realizing various possible electrical connection modes, having high adjustability and realizing the function of free electrical connection.

Bus equivalence, that is, the 4 m-th bus is the same as the access point accessible by the (4m-3) th bus, and the (4m-1) th bus is the same as the access point accessible by the (4m-2) th bus. For example, if there are eight access points, the first access point, the second access point … … to the eighth access point. There are two buses, a first bus and a second bus. The first bus and the second bus are equivalent if the points accessible by the first bus can be first, second, third, and fourth access points and the points accessible by the second bus can also be first, second, third, and fourth access points.

Referring to fig. 2, an embodiment of the present invention provides an electrical connection module, which is a specific example when m is 1 and n is 16. In this case, there are 4 buses, including a first bus, a second bus, a third bus, and a fourth bus. There are 64 access points, including first through sixty-fourth access points. For example, one way of connecting the bus and the access point is as follows: the access points which can be accessed by the first bus and the fourth bus comprise a thirty-third access point to a sixty-fourth access point; the access points accessible to the second bus and the third bus include first to thirty-second access points. The electrical connection module is used for realizing the function of realizing free electrical connection between 4 public output channels and 64 arbitrary input points, and can be used for power supply and distribution, signal switching, routing control and the like.

Furthermore, the module can adopt STM32F103ZE series single-chip microcomputer, and the bus matrix switch routing control is realized.

Fig. 5 is a partial schematic view of an application scenario of an electrical connection module provided in an embodiment of the present invention when m is 1 and n is 8. In this case there are 4 buses and 64 access points. There are 64 access points, i.e., J1-J64, on each electrical connection module (also referred to as a switchboard) that form a complex relay array connection. The principle of any two points of 64 points being conducted is as follows (screenshot of partial schematic diagram):

(1) two-wire system conduction testing principle

As can be seen from fig. 5: in the figure, four buses are respectively BUS1, BUS2, BUS3 and BUS4, and the connection points of the BUS1 and the BUS4 can be J-57, J-58 and J-59, so that BUS1 is equivalent to BUS 4. The same applies to BUS2 and BUS 3.

The connection of any two points in the figure can be divided into two types, one type is the connection between different buses, namely the connection between the points of the BUS1(BUS4) and the BUS2(BUS3), and the other type is the connection between the same buses, namely the connection between the points of the BUS1(BUS4) or the connection between the points of the BUS2(BUS 3).

When making connections between different buses, four combinations of buses are used: the relationship between the BUS1 and BUS2, BUS1 and BUS3, BUS4 and BUS2, and BUS4 and BUS3 are equivalent, so that the connection between points on different buses can be completed by using one combination of BUS1 and BUS2, for example, the connection between access points J-6 and J-59, J-7 and J-58, and J-8 and J-57 in FIG. 5. To generalize from part to all, the electrical connection between any one of the first to thirty-second access points and any one of the thirty-third to sixty-fourth access points may be conducted and connected through the first bus and the second bus, or may be conducted and connected through the fourth bus and the third bus, or may be conducted and connected through the first bus and the third bus, or may be conducted and connected through the second bus and the fourth bus.

When conducting connection of points on the same BUS is carried out, the two conditions can be divided into two conditions, one is that on a BUS1(BUS4) BUS, the BUS used in connection is combined into a BUS1 and a BUS4, and conducting connection of any two points on the BUS1(BUS4) can be completed, for example, conducting connection between access points J-58 and J-57, J-58 and J-59, and J-9 and J-57 in FIG. 5; the other is that on the BUS2(BUS3) BUS, the combination of the buses used in connection is BUS2 and BUS3, and the connection between any two points on BUS2(BUS3) can be completed, such as the connection between access points J-6 and J-7, J-6 and J-8, and J-7 and J-8 in FIG. 5. The whole appearance can be popularized from part to part, and the electric connection between any two access points in the first to thirty-second access points can be conducted and connected through the second bus and the third bus; in the thirteenth to sixty-fourth access points, the electrical connection between any two access points may be conducted through the first bus and the fourth bus.

Similarly, any two points on the whole switching board can be connected by one of three combinations of the BUS1 and BUS2, the BUS1 and BUS4, and the BUS2 and BUS 3.

(2) Four-wire system conduction connection principle

In another embodiment of the present invention, when m is 1 and n is 8, the access points are divided into thirty-two groups, each group includes two access points electrically connected to each other, which means that the four-wire system connection is conducted. In this case, there are 32 access points on each paddle, for example, where J1 and J64 are connected to the same point, and J2 and J63, J3 and J62, J4 and J61, J5 and J60 … …, J32 and J33 are connected to the same point. We refer to these 32 points for the moment as D1-D32, where each point can be connected to BUS1, BUS2, BUS3, BUS4, and can be selectively connected to BUS1 and BUS2 or BUS3 and BUS4 through relays. In the case of a four-wire measurement, the measurement of any two points on the whole board can be summarized as a case: one point of the two points is connected with a BUS1 and a BUS2, and the other point is connected with a BUS3 and a BUS4, so that two selectable measurement combinations are provided, namely BUS1 and BUS3, BUS2 and BUS4 or BUS1 and BUS4, BUS2 and BUS3, and considering the two-wire measurement condition, the combination of the BUS1 and the BUS4, and the BUS2 and the BUS3 is more suitable.

(3) Two-wire system conduction connection principle

In yet another embodiment of the present invention, when m is 1 and n is 8, the buses include a first bus, a second bus, a third bus and a fourth bus; when the conductive connection between the two-wire input and output is carried out, the first BUS and the fourth BUS are suspended (namely, the BUS1 and the BUS4 are suspended). In this case, only 32 aps are connected to each paddle, and these aps are connected to J1-J32, respectively. We refer to these 32 points for the moment as D1-D32, where each point can be connected to BUS2, BUS3, and can be selectively connected to either BUS2 or BUS3 via a relay.

From the above, it can be seen that the electrical connection module in this embodiment implements the function of free electrical connection between 4 common output channels and 64 arbitrary input points, and can be used for power supply and distribution, signal switching, routing control, and the like. The degree of freedom is high, can switch as required at any time to improve production efficiency, the cost is reduced.

Referring to fig. 3, further, in order to facilitate the measurement of whether the module is turned on or not, and to debug whether the electrical connection module reaches a desired connection state, an embodiment of the present invention provides an electrical connection module, where the module further includes an output channel electrically connected to the bus, and the electrical connection between any two points on the module can be measured through the output channel. According to the measuring result, the feedback and the adjustment can be carried out in time. The reliability of the electrical connection module is improved.

Further, the type of the relay can be selected from various types available on the market according to requirements, for example, the relay can be selected from Fuji Tong (FUJITSU) relay series, such as the type NA12W-K and the type NA 24W-K; RY5W-K, RY12W-K, RY 24W-K; NY12W-K, NY24W-K and the like. Preferably, when m is 1 and n is 16, NA24W-K is used as the relay.

Referring to fig. 4, further, an embodiment of the present invention provides an electrical connection module, where the module further includes a single chip microcomputer electrically connected to the bus and the relay, and the bus matrix switch routing control is implemented by processing functions and programs of the single chip microcomputer. For example, the electrical connection module can adopt STM32F103ZE series single-chip microcomputer.
