[0024] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] See also Figure 1 and Figure 4 As shown, the utility model discloses a three-core three-way connector 100, including a housing 1 and a cable 2, wherein the housing 1 is provided with a first interface 11, a second interface 12 and a third interface 13, and a connection cavity is provided inside the housing 1, wherein the connection cavity includes a first connection cavity connecting the first interface 11 and the second interface 12 and a second connection cavity connecting the first connection cavity and the third interface 13, and the first connection cavity and the second connection cavity are perpendicular to each other. In this way, the three-core three-way connector 100 is T-shaped as a whole.

[0026] The cable 2 is used to pass through the connection cavity to connect to an external device. Both ends of the cable 2 are exposed on the outside of the shell 1. The cable 2 includes a first cable 21 that passes through the first interface 11 and is partially accommodated in the first connection cavity, and a second cable 22 that passes through the third interface 13 and is partially accommodated in the second connection cavity. The first cable 21 and the second cable 22 are electrically connected.

[0027] See also Figure 2 and Figure 3 As shown, the three-core three-way connector 100 also includes a terminal block 3 for connecting the first cable 21 and the second cable 22. The terminal block 3 is accommodated in the first connection cavity and is provided with a first through slot 31 communicating with the first interface 11 and a second through slot 32 communicating with the third interface 13. One end of the first cable 21 passes through the first through slot 31 and is fixed inside the terminal block 3. One end of the second cable 22 passes through the second through slot 32 and is fixed inside the terminal block 3, so that the first cable 21 is electrically connected to the second cable 22 through the terminal block 3. In this way, only one terminal block 3 is needed to electrically connect the two cables, which greatly saves production costs. In this embodiment, because the connector is a three-core connector, three terminals 3 are also provided. In other embodiments, it can be adjusted according to actual conditions, and there is no limitation on this.

[0028] Specifically, the first through slot 31 and the second through slot 32 are connected to each other, and a first positioning portion 310 is provided on one side of the first through slot 31 close to the second through slot 32, so that the positioning member 4 extends into the first through slot 31 and cooperates with the first positioning portion 310 to fix one end of the second cable 22 inside the wiring terminal 3. In this embodiment, the first positioning portion 310 is a screw hole, and the positioning member 4 is a screw. The second cable 22 is fixed in the second through-hole through the cooperation between the screw and the screw hole. Of course, in other embodiments, the second cable 22 can be fixed by other methods, which are not limited to this, and it is only necessary to ensure that the second cable 22 does not fall off.

[0029] Preferably, a mounting portion 111 is provided at the first interface 11 of the housing 1, a through hole 1110 corresponding to the first through slot 31 is provided in the mounting portion 111, the first interface 11, the through hole 1110 and the first through slot 31 are interconnected, and the positioning member 4 enters the first through slot 31 through the first interface 11 and the through hole 1110 and cooperates with the first positioning portion 310. That is, after one end of the second cable 22 extends into the wiring terminal 3, a screw can be screwed into the first through slot 31 through the first interface 11, and then the second cable 22 can be fixed in the wiring terminal 3.

[0030] A second positioning portion 311 is provided on one side of the wiring terminal 3 close to the first through slot 31 , and an extension direction of the second positioning portion 311 is perpendicular to an extension direction of the first through slot 31 , so that one end of the first cable 21 can be fixed inside the wiring terminal 3 by passing the positioning member 4 through the second positioning portion 311 .

[0031] In this embodiment, the installation of the cable 2 includes the following steps:

[0032] ① Fix the wiring terminal 3 inside the first connection cavity, and align the first through slot 31 and the first interface 11, and the second through slot 32 and the third interface 13 with each other;

[0033] ② Insert one end of the second cable 22 into the second through slot 32 along the third interface 13 to enter the interior of the wiring terminal 3;

[0034] ③ Extend the positioning member 4 into the first through slot 31 along the first interface 11 and the through hole 1110 until it cooperates with the first positioning portion 310 to fix one end of the second cable 22 inside the wiring terminal 3;

[0035] ④ Extend one end of the first cable 21 into the first through slot 31 along the first interface 11 and the through hole 1110 , and then insert the positioning member 4 from the second positioning portion 311 to fix one end of the first cable 21 inside the wiring terminal 3 .

[0036] This installation method is not only simple to operate, but also very convenient when replacing the cable 2.

[0037] It should be noted that the terminal block 3 is not only applicable to three-core connectors, but also applicable to two-core, four-core, five-core and other connectors, and the same effect can be achieved by simply displacing multiple terminal blocks 3. It should not be considered that it is only applicable to the three-core three-way connector 100 of the present invention.

[0038] Preferably, when the second interface 12 is configured as a plug-in type, the end of the wiring terminal 3 close to the second interface 12 can be used as a plug-in interface to be connected to an external terminal. In this way, electrical connection in three directions is achieved through one wiring terminal 3, which makes the plug-in cable more flexible and further saves production costs.

[0039] The three-core three-way connector 100 also includes a cover plate 6 fixedly connected to the mounting portion 111, the cover plate 6 covers the first interface 11, and is provided with a threading opening 60 corresponding to the through hole 1110, the threading opening 60 and the through hole 1110 are interconnected, and the first cable enters the first through groove 31 through the threading opening 60 and the through hole 1110.

[0040] A clamping groove 1111 is provided on the side wall of the mounting portion 111 , and a clamping portion 61 is correspondingly provided on the cover plate 6 . The clamping portion 61 cooperates with the clamping groove 1111 to achieve a fixed connection between the cover plate 6 and the housing 1 .

[0042] Specifically, the sealing assembly 5 includes a sealing body 51 fixedly connected to the housing 1, a sealing member 52 accommodated inside the sealing body 51, and a locking member 53 locked and connected to the sealing body 51. The sealing body 51 is provided with an external thread 510 on one side close to the first interface 11, and the locking member 53 is provided with an internal thread 530. The external thread 510 and the internal thread 530 cooperate with each other to achieve a locking connection between the locking member 53 and the sealing body 51. A limiting portion 512 is provided inside the sealing body 51, and the sealing member 52 is limited and fixed between the limiting portion 512 and the locking member 53.

[0043] Of course, the second interface 12 and the third interface 13 also need to be sealed and fixed, but there is no restriction on the sealing method, which can be adjusted according to actual conditions.

[0044] The housing 1 is provided with a clamping member 14, and the sealing body 51 is correspondingly provided with a clamping groove 511. When the sealing body 51 is sleeved on the housing 1, the clamping member 14 passes through the clamping groove 511 to achieve a fixed connection between the housing 1 and the sealing body 51. In this way, disassembly is also relatively easy.

[0045] In summary, the three-core three-way connector 100 of the utility model opens a first through slot 31 connected to the first interface 11 and a second through slot 32 connected to the third interface 13 inside the wiring terminal 3, so that one end of the first cable 21 can pass through the first through slot 31 and be fixed in the wiring terminal 3, and one end of the second cable 22 can pass through the second through slot 32 and be fixed in the wiring terminal 3. Only one wiring terminal 3 is used to achieve the electrical connection between the first cable 21 and the second cable 22, thereby reducing the production cost and being practical.
