Detailed Description

The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Referring to fig. 1, in the present embodiment, the width direction, the length direction, and the height direction are as shown in the figure.

Referring to fig. 1 to 8 in combination, the present invention provides a modular plug assembly. The modular plug assembly in an embodiment of the invention comprises a first module 1 and a second module 2 which are plugged into each other. Wherein, be provided with the boss along its length direction on the first module 1, be provided with the recess that suits with the boss along its length direction on the second module 2. The projection and the groove cooperate to allow the first module 1 and the second module 2 to be plugged into each other. This means that the degree of freedom of the first module 1 and the second module 2 in the height direction and the width direction is limited, and the structure is simple and practical. In this embodiment, the boss is the T font, and the recess is the character form of folding the line that suits with the boss. Of course, the manner of plugging the first module 1 and the second module 2 is not limited to the above manner.

Further, as shown in fig. 1 and 4, a clamping block 10 is arranged on the boss, a clamping groove 11 is arranged in the groove, the clamping block 10 is adapted to the position of the clamping groove 11, and the clamping block 10 and the clamping groove 11 cooperate to define the relative position of the first module 1 and the second module 2 in the length direction. Through the structure that sets up fixture block 10, draw-in groove 11 and the grafting structure of the aforesaid boss of cooperation and recess, just can inject the position relation of first module 1 and second module 2 totally six dimensions on direction of height, width direction and length direction well, and then can guarantee first module 1 and second module 2's connection stability effectively.

The first module 1 and the second module 2 in this embodiment may be formed by 3D printing technology or by other feasible means.

At least four groups of four-way holes 3 communicating the width direction and the height direction of the first module 1 are formed in the length direction of the first module; the second module 2 is provided with first through holes 4 which penetrate through the second module 2 in the width direction at positions corresponding to the four through holes 3 one by one. The axes of the holes in the width direction of the four through holes 3 and the axis of the extension direction of the boss are perpendicular to each other in the same plane, and the axis of the first through hole 4 and the axis of the extension direction of the groove are perpendicular to each other in the same plane. In other words, the boss is disposed on one side in the width direction of the first module 1 (i.e., the boss is located in the same plane as the opening in the width direction of the four-way hole 3), and the groove is disposed on the opposite side in the width direction of the second module 2 from the boss (i.e., the groove is located in the same plane as the first through hole).

In the present embodiment, the first module 1 is used to realize multi-dimensional communication connection with the external connection component, and therefore, the structure of the first module 1 is slightly more complex than that of the second module 2.

Specifically, referring to fig. 1 to 3, the first module 1 is substantially a rectangular parallelepiped structure, four sets of four through holes 3 are provided at intervals along the length direction of the first module 1, and each set of four through holes 3 communicates with the width direction and the height direction of the first module 1, respectively. Further, the distances between two adjacent groups of four through holes 3 are equal. Still further, the axis of the hole in the height direction in the four-way hole 3 is perpendicular to the axis of the hole in the width direction, and the axis of the hole in the height direction is also perpendicular to the upper and lower surfaces of the first module 1.

The reason why four sets of four through holes 3 are provided is that: the first group and the second group of the four through holes 3 are used for IIC communication, and the host machine sends instructions to all the slave machines through an IIC communication protocol; for example, a bidirectional data line SDA may be inserted into the first set of four through holes 3, and the slave may send information to the host through the data line SDA; a clock signal line SCL can be arranged in the second group of four through holes 3 in a penetrating mode, and synchronous operation among all the slave machines can be guaranteed through the clock signal line; the fourth through holes 3 of the third group and the fourth group are used for an external power supply and a ground wire.

Referring to fig. 4 and 5, the second module 2 is also substantially rectangular parallelepiped, and four first through holes 4 corresponding to the four sets of four through holes 3 are provided at intervals along the length direction of the second module 2, and each first through hole 4 communicates with the width direction of the second module 2.

First electric connector 5 penetrating through the height direction of the first module 1 is arranged in the axial direction of the hole formed in the height direction of each group of four through holes 3 in a penetrating mode, and second electric connector 6 penetrating through the width direction of the first module 1 and the second module 2 is arranged in the axial direction of the hole formed in the width direction of each group of four through holes 3 and the axial direction of the first through hole 4 in a penetrating mode.

In the present embodiment, the length of the first electrical connector 5 is slightly greater than the height of the first module 1. That is, both ends of the first electrical connector 5 are respectively higher than the upper and lower surfaces of the first module 1 by a certain distance. The purpose of this arrangement is to realize communication connection in the height direction between two adjacent first modules 1 through the first electrical connectors 5 or to provide electrode interfaces for external connection parts when a plurality of first modules 1 are stacked in the height direction.

Similarly, the length of the second electrical connector 6 is slightly greater than the overall width of the first module 1 and the second module 2 after being plugged. Namely, two ends of the second electrical connector 6 are respectively higher than the front and rear surfaces of the first module 1 and the second module 2 after being plugged by a certain distance. In this way, when the first module 1 and the second module 2 are butted in the width direction, two adjacent plugged assemblies can be connected in communication in the width direction through the second electrical connector 6 or provide an electrode interface for external connection parts.

Wherein the first electrical connector 5 and the second electrical connector 6 are conducted with each other. Further, the first electrical connector 5 and the second electrical connector 6 may also be arranged perpendicular to each other. Of course, in other embodiments, two first electrical connectors 5 butted against each other and two second electrical connectors 6 butted against each other may be provided, as long as the first electrical connectors 5 and the second electrical connectors 6 are ensured to be in conduction with each other.

According to the module plug-in assembly provided by the invention, the four-way hole 3 penetrating through the height direction and the width direction of the first module 1 is formed on the first module 1 which is plugged with each other, the first through hole 4 penetrating through the width direction of the second module 2 is formed on the second module 2, the first electric connecting piece 5 is arranged along the axial direction of the hole formed in the height direction of the four-way hole 3, and the second electric connecting piece 6 which is mutually communicated with the first electric connecting piece 5 is arranged along the axial direction of the hole formed in the width direction of the four-way hole 3 and the axial direction of the first through hole 4, so that the aim of multi-dimensional communication can be achieved only by using the first module 1 and the second module 2, and the overall structure size.

Referring to fig. 6, in a preferred embodiment, a liquid metal liquid is also preset in each four-way hole 3, and the conducting position of the first electric connector 5 and the second electric connector 6 is immersed in the liquid metal liquid.

This is intended to further improve the stability of the conductive connection of the first electrical connection 5 to the second electrical connection 6. The liquid metal can be gallium-indium alloy, and the proportion can be determined according to the temperature of the use environment, for example, the liquid metal can be formed by mixing 75% of gallium and 25% of indium at normal temperature. The gallium-indium alloy has the advantages of strong stability, good conductivity and the like at normal temperature and normal pressure, and proper liquid metal can be selected to replace the gallium-indium alloy according to the use environment of the module plug-in component.

The following further describes the specific structure of the first module 1 and the second module 2 provided by the embodiment of the present invention according to two use cases of the first module 1 and the second module 2:

firstly, the method comprises the following steps: the first module 1 and the second module 2 are only butted in a horizontal plane to form a topology structure detection networking:

referring to fig. 1 to 3, in this embodiment, a second through hole 7 penetrating the width direction of the first module 1 is provided in the width direction of the first module 1; and a third through hole 13 penetrating the width direction of the second module 2 is formed in the width direction of the second module 2, and the second through hole 7 is communicated with the third through hole 13.

Specifically, the electrical connection can be directly passed through the second through hole 7 and the third through hole 13 to realize the communication connection between the two adjacent first modules 1 and the second module 2 so as to identify the topological connection relationship between the two modules. Of course, a plurality of second through holes 7 may be disposed on the first module 1, a plurality of third through holes 13 may be disposed on the second module 2, and the plurality of second through holes 7 and the plurality of third through holes 13 are respectively connected in a one-to-one correspondence manner through the electrical connection members to meet the use requirements in various application scenarios.

II, secondly: the first module 1 and the second module 2 are butted in a horizontal plane and stacked in a vertical plane to form a topology detection network:

referring to fig. 2 and 3, in this embodiment, at least one fourth through hole 8 is formed through the upper surface and the back surface of the first module 1; at least one fifth through hole 9 penetrating through the lower surface and the back surface of the first module 1 is formed on the lower surface and the back surface.

Specifically, because a plurality of first modules 1 and a plurality of second modules 2 are stacked in the vertical plane to form the topology detection networking, in order to ensure that the topology detection networking can also be in communication connection with external connecting components in the vertical direction, openings need to be arranged at corresponding positions of the first modules 1 to meet the use requirements of unidirectional communication serial ports. Thus, the first module 1 is arranged in this way. The fourth through hole 8 communicates with the upper surface and the back surface of the first module 1, and the fifth through hole 9 communicates with the lower surface and the back surface of the first module 1. Therefore, in the present embodiment, the fourth through hole 8 and the fifth through hole 9 are both obliquely provided through holes. The use requirements can be well met by arranging the fourth through hole 8 and the fifth through hole 9.

Further, the opening positions of the fourth through hole 8 and the fifth through hole 9 on the back surface of the first module 1 are offset from each other. The electric connectors penetrating through the fourth through hole 8 and the fifth through hole 9 are prevented from being wound and interfered with each other. In addition, the axes of the openings of the fourth through hole 8 and the fifth through hole 9 at the upper and lower surfaces of the first module 1 coincide with each other. Of course, in other embodiments, a plurality of fourth through holes 8 and fifth through holes 9 may be provided, and the axes of the holes of the fourth through holes 8 and fifth through holes 9 at the upper and lower surfaces of the first module 1 may be provided in other forms according to the actual situation.

In a preferred embodiment, magnetic connections are also provided on the first module 1 and the second module 2. When the first module 1 and the second module 2 are butted in a horizontal plane and stacked in a vertical plane to form a topological structure detection networking, two adjacent first modules 1 and second modules 2 in the vertical direction can be more firmly connected together by arranging the magnetic connecting piece, so that the connection stability of the topological structure detection networking is improved, and the accuracy of a detection result is further ensured.

Correspondingly, referring to fig. 1 to 5 in combination, in order to fix the magnetic connector, a first socket 12 is provided on the first module 1, and a second socket 14 is further provided on the second module 2, wherein the first socket 12 and the second socket 14 are respectively used for plugging the magnetic connector. Of course, a magnetic connector or other connecting structure capable of achieving the above technical effects may be separately provided on the first module 1 or the second module 2.

The first electrical connector 5 and the second electrical connector 6 in this embodiment are in a pogopin-type design. Through the adoption of the first electric connecting piece 5 and the second electric connecting piece 6 which are designed in a pogopin snap-in type mode, the stable connection between the electric connecting pieces and the stable transmission of signals can be guaranteed no matter whether the first module 1 and the second module 2 are fixed in a plug-in mode or a magnetic suction mode.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
