BRIEF DESCRIPTION OF DRAWINGS

[0026] The preferred embodiments of the present application will be described in detail below with reference to the drawings, in which:

[0027] Figure 1 A terminal connecting device according to one embodiment of the present application is shown.

[0028] In the drawings, the same components are designated by the same reference numerals. The drawings are not drawn according to the actual proportions. DETAILED DESCRIPTION

[0029] In order to make the technical scheme and advantages of the present application clearer, the exemplary embodiments of the present application will be further described in detail below with reference to the drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. And the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0030] An embodiment of the present application proposes a terminal connecting device. As shown in Figure 1As shown, the terminal connecting device comprises a base 1 and a first terminal block 2 arranged on the base 1. The base 1 functions to define the first terminal block 2. The first terminal block 2 comprises a first terminal 21, a second terminal 22, a third terminal 23 and a fourth terminal 24. In use, the first terminal 21 is used to electrically connect a power supply 3 to a thermostat 4 in a zero line mode. That is, one end of the first terminal 21 is connected to a zero line of the power supply 3, and the other end is connected to the thermostat 4. The second terminal 22 is used to electrically connect the power supply 3 to the thermostat 4 in a fire line mode. That is, one end of the second terminal 22 is connected to a fire line of the power supply 3, and the other end is connected to the thermostat 4. It can be seen that the thermostat 4 can be connected to the power supply through the first terminal 21 and the second terminal 22. The third terminal 23 is used to electrically connect the first terminal 21 to a first thermal valve 5 in a zero line mode. That is, the first thermal valve 5 is connected to the third terminal 23, and the third terminal 23 is connected to the first terminal 21, so that the first thermal valve 5 is powered through the connection between the two terminals. The fourth terminal 24 is used to signal connect the first thermal valve 5 to the thermostat 4. That is, one end of the fourth terminal 24 is connected to the thermostat 4, and the other end is connected to the first thermal valve 5. It can be seen that the thermostat 4 can be signal connected to the first thermal valve 5 through the fourth terminal 24, so as to control the first thermal valve 5.

[0031] In an air conditioning system, a thermostat 4 is arranged in a required room, which is used to control a first thermal valve 5 on a branch loop corresponding to the room, and both the thermostat 4 and the first thermal valve 5 need to be connected to a power supply. Through the terminal connecting device of the present application, the power supply is connected to the thermostat 4 through the first terminal 21 and the second terminal 22 to supply power to the thermostat 4. The first thermal valve 5 is connected to the first terminal 21 through the third terminal 23 to provide power connection for the first thermal valve 5. The two ends of the fourth terminal 24 are respectively connected to the thermostat 4 and the first thermal valve 5, so that the thermostat 4 can control the first thermal valve 5. It can be seen that through the terminal connecting device of the present application, it is not necessary to arrange a power supply reservation box beside the header tank as in the prior art, and a plurality of parallel connectors do not need to be connected to the power supply. The power supply 3 only needs to be introduced into the terminal connecting device through the first terminal 21 and the second terminal 22, which has a good construction appearance and is power specification.

[0032] According to the present application, in the first terminal group 2, the number of the third terminal 23 and the fourth terminal 24 is set according to the number of the first thermoelectric valve 5. For example, in one air conditioning project, if the ground distribution reservoir and the top distribution reservoir are configured, for one room, the temperature controller in the room needs to control a plurality of first thermoelectric valves 5. In the case of multiple first thermoelectric valves 5, the first terminal group 2 includes a plurality of third terminals 23 and a plurality of fourth terminals 24. It is easy to understand that the third terminal 23 is electrically connected to the first terminal 21, and each third terminal 23 is used to one-to-one matching connection of the first thermoelectric valve 5. Each fourth terminal 24 is signal connected to the temperature controller 4 and is used to one-to-one matching connection of the first thermoelectric valve 5. For example, Figure 1 In the second first terminal group 2 from left to right in FIG. 1, there are two first thermoelectric valves 5, each corresponding to one third terminal 23 and one fourth terminal 24, and the third terminals 23 corresponding to different first thermoelectric valves 5 are connected in turn, and the fourth terminals 24 corresponding to different first thermoelectric valves 5 are connected in turn. It can be seen that if the corresponding room needs to add first thermoelectric valves 5, only the third terminal 23 and the fourth terminal 24 need to be added in the corresponding first terminal group 2 to complete the electrical connection and control of the added first thermoelectric valves 5. In the first terminal group 2, the third terminals 23 are connected in turn, and one of the third terminals 23 is electrically connected to the first terminal 21. In actual connection, only the upper end of the terminal to be connected, for example Figure 1 in FIG. 1, can be completed by using an electrical connection line, thereby realizing circuit connection and avoiding multiple electrical connection joints. At the same time, the fourth terminals 24 are connected in turn, and only the upper end of the fourth terminal 24 to be connected, for example Figure 1 in FIG. 1, can be completed by using a signal connection line, thereby realizing signal connection, avoiding multiple parallel joints, and ensuring quality perception.

[0033] According to the type of the first thermoelectric valve 5, the connection requirement with the power supply 3 is different, for example, some first thermoelectric valves 5 also need to be connected with the live wire of the power supply 3. According to the present application, the fifth terminal 25 can also be added in the first terminal group 2. The fifth terminal 25 is used for live wire electrical connection between the second terminal 22 and the first thermoelectric valve 5. That is, if the first thermoelectric valve 5 needs to be connected to the power supply 3 by the live wire, only the fifth terminal 25 needs to be added, so that the fifth terminal 25 is connected to the second terminal 22 and then connected to the first thermoelectric valve 5.

[0034] The first terminal groups 2 are multiple, the first terminals 21 in each first terminal group 2 are connected in sequence, and the second terminals 22 in each first terminal group 2 are connected in sequence. In actual operation, for example, there are multiple rooms, and a thermostat 4 is arranged in each room for independently controlling the temperature of the room, and the first terminal group 2 corresponds to the thermostat 4 for ensuring the connection of the corresponding thermostat 4 and the first thermoelectric valve 5 of the room. In particular, one first terminal 21 and one second terminal 22 in each first terminal group 2 are directly connected to the power supply, and the other first terminals 21 are connected to the adjacent first terminals 21, and the second terminals 22 are connected to the adjacent second terminals 22, and such indirect connection can also achieve connection with the power supply. It can be seen that in the terminal connection device, only one first terminal group 2 is connected to the power supply, and the remaining first terminal groups 2 are indirectly connected to the power supply. This arrangement can effectively avoid the problem of excessive power lines, help to standardize electrical connections, and simplify connection operations.

[0035] The terminal connection device further comprises a second terminal group 6. The second terminal group 6 comprises a sixth terminal 61, a seventh terminal 62, an eighth terminal 63, and a ninth terminal 64. The sixth terminal 61 is used for zero-line type electrical connection to the power supply 3. The seventh terminal 62 is used for fire-line type electrical connection to the power supply 3. Specifically, the sixth terminal 61 is electrically connected to the first terminal 21, and the seventh terminal 62 is electrically connected to the second terminal 22, for ensuring electrical connection. The eighth terminal 63 is used for zero-line type electrical connection between the sixth terminal 61 and the second thermoelectric valve 7. The ninth terminal 64 is used for fire-line type electrical connection between the seventh terminal 62 and the second thermoelectric valve 7. In actual use, some rooms such as kitchens and toilets do not necessarily have a thermostat, for example, in hot weather, in air conditioning cooling mode, considering the risk of condensation, the branch waterway corresponding to the kitchen and toilet needs to be closed. In air conditioning heating mode, the branch waterway corresponding to the kitchen and toilet is opened. It can be seen that whether the room has a thermostat or not, the terminal connection device can supply power to the second thermoelectric valve 7, and in particular, the second terminal group 6 can not be directly connected to the power supply 3, and the circuit can also be turned on.

[0036] A changeover switch 8 is arranged between the seventh terminal 62 and the second terminal 22. Thus, the opening and closing of the second thermoelectric valve 7 in the room can be controlled by operating the changeover switch 8, for realizing seasonal conversion.

[0037] An air switch 9 is arranged on the base 1. The air switch 9 is used to connect the first terminal 21 and the second terminal 22 to the power supply 3. It is easy to understand that the air switch 9 is arranged on the line directly connecting the first terminal 21 and the second terminal 22 to the power supply, for ensuring electrical safety.

[0038] The base 1 is provided with a guide rail 11. The terminal blocks (including the first terminal block 21, the second terminal block 22, the third terminal block 23, the fourth terminal block 24, the fifth terminal block 25, the sixth terminal block 61, the seventh terminal block 62, the eighth terminal block 63 and the ninth terminal block 64) are slidably connected with the guide rail 11. This arrangement is simple, and the number and position of the terminal blocks can be conveniently adjusted according to whether the room has a temperature controller, the number of thermoelectric valves and the like.

[0039] The base 1 is configured as a box (not shown in the figure) with only one open side. The first terminal block group 2 and the second terminal block group 6 are encapsulated in the box, and a box cover (not shown in the figure) is arranged at the open side of the box. It is easy to understand that the guide rail 11 is preferably arranged on the wall of the box opposite to the box cover. This arrangement can integrate the terminal block connecting device structure as a whole, so as to facilitate manufacturing, transportation and installation, and can effectively protect the first terminal block group 2 and the second terminal block group 6, and ensure the safety of electricity use.

[0040] A grounding body (not shown in the figure) is arranged on the box. The IP level of the box is not less than IP43. The operating member of the change-over switch 8 can be arranged on the box cover, so as to be convenient to operate.

Therefore, the appended claims are intended to be interpreted as including all the preferred embodiments and all changes and / or modifications falling within the scope of the present application, and all changes and / or modifications made to the embodiments according to the present application should be covered by the protection scope of the present application.
