[0019] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0020] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0021] In the present invention, unless otherwise specified, directions such as "up" and "down" are usually used in reference to the directions shown in the drawings, or in reference to the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "left" and "right" are usually used in reference to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directions are not used to limit the present invention.

[0022] See also Figure 1-5 , the utility model provides the following technical solutions:

[0023] Specifically, it refers to a split-type DC power socket, including a plastic body 3, a shell 1 sleeved on the outer surface of the plastic body 3, and a copper core 4 arranged in the plastic body 3, so that the plastic body 3 and its internal connection structure are formed with the shell 1, and a first terminal installation groove 6 is provided on the back of the plastic body 3, and a through hole 5 is provided between the first terminal installation groove 6 and the inside of the plastic body 3. The rear end of the copper core 4 extends into the first terminal installation groove 6 through the through hole 5, and the copper core 4 and the plastic body 3 are fixedly installed in the plastic body 3 by a riveting process, and the back of the plastic body 3 is provided with a through hole 5 connected to the first terminal installation groove 6. The first terminal mounting groove 6 is adapted to and sleeved on the first terminal 7 on the outer surface of the rear end of the copper core 4. The first terminal 7 is also fixedly mounted on the copper core 4 by a riveting process. A plurality of contact protrusions 15 in a circular array in contact with the copper core 4 are fixedly connected on the back of the first terminal 7 close to the copper core 4. The existing RCA socket with an integrated copper core is modified into a split structure by the above method, so that the RCA socket is modularized, which simplifies the production difficulty of the RCA socket. At the same time, the split DC power socket can meet the high current requirements through the riveting process and the plurality of contact protrusions 15, and will not affect the use of the RCA socket.

[0024] Specifically, a shielding sheet 2 is fixedly connected to the front of the plastic body 3, and the shielding sheet 2 is fixed to the left and right sides of the plastic body 3 by riveting. Therefore, the shielding sheet 2 improves the anti-interference ability of the RCA socket and ensures the use effect of the RCA socket.

[0025] Specifically, a second terminal mounting groove 10 and a third terminal mounting groove 14 are provided on the back of the plastic body 3. The second terminal mounting groove 10 and the third terminal mounting groove 14 are respectively located on both sides of the first terminal mounting groove 6, and the two are connected. A second terminal 8 inserted into the second terminal mounting groove 10 is provided on the back of the plastic body 3. A third terminal 13 inserted into the third terminal mounting groove 14 is provided on the back of the plastic body 3. At the same time, a vertical plate on one side of the third terminal 13 extends into the second terminal mounting groove 10. A spring for pressing the third terminal 13 is provided on the side of the second terminal 8 close to the third terminal 13. When in use, the second terminal 8 is first inserted into the second terminal mounting groove 10, and then the third terminal 13 is inserted into the third terminal mounting groove 14. At the same time, the vertical plate of the third terminal 13 is located on the side of the elastic clamping piece 9 facing the second terminal 8 and contacts the elastic clamping piece 9. Therefore, the third terminal 13 will squeeze the elastic clamping piece 9 during the process of inserting into the third terminal mounting groove 14, causing the elastic clamping piece 9 to deform. When the third terminal 13 is fully inserted into the third terminal mounting groove 14, the elastic clamping piece 9 releases the reaction force, thereby forming a clamping effect on the third terminal 13.

[0026] Specifically, two slots 16 are provided on the surface of one side of the vertical plate of the third terminal 13 facing the elastic clamping plate 9, and a clamping block 17 adapted to the slot 16 is fixedly connected to the side of the elastic clamping plate 9 close to the slot 16. Therefore, when the elastic clamping plate 9 clamps the third terminal 13, the clamping block 17 slides into the slot 16, thereby completing the restriction on the third terminal 13 and avoiding the problem of looseness of the second terminal 8 and the third terminal 13 after installation.

[0027] Specifically, a snap-on groove 11 connected to the second terminal mounting groove 10 is formed on the outer surface of the plastic body 3, and a snap-on elastic piece 12 adapted to the snap-on groove 11 is provided on the side of the second terminal 8 close to the snap-on groove 11, so that when the second terminal 8 is inserted into the second terminal mounting groove 10, the snap-on elastic piece 12 is squeezed by the inner wall of the second terminal mounting groove 10 and deformed. When the second terminal 8 is completely inserted into the second terminal mounting groove 10, the snap-on elastic piece 12 loses its squeezing and thus bounces into the snap-on groove 11 to complete the fixation of the second terminal 8. This simplifies the operational difficulty during the installation of the second terminal 8 and the third terminal 13, and can ensure the efficiency and speed of the later RCA socket assembly.

[0028] The working principle of the split DC power socket provided by the utility model is as follows: first, the rear end of the copper core 4 is extended into the first terminal installation groove 6 through the through hole 5, and fixed to the plastic body 3 by a riveting process, then the first terminal 7 is inserted into the first terminal installation groove 6, and sleeved on the rear end of the copper core 4, and fixedly installed on the copper core 4 by a riveting process, thereby completing the fixation between the first terminal 7 and the copper core 4;

[0029] Then insert the second terminal 8 into the second terminal mounting groove 10. At this time, the snap-on elastic sheet 12 is squeezed by the inner wall of the second terminal mounting groove 10 and deformed. When the second terminal 8 is completely inserted into the second terminal mounting groove 10, the snap-on elastic sheet 12 loses the squeezing and thus bounces into the snap-on groove 11, completing the fixation of the second terminal 8. Finally, insert the third terminal 13 into the third terminal mounting groove 14. At the same time, the vertical plate of the third terminal 13 is located on the side of the elastic clamping sheet 9 facing the second terminal 8 and contacts with the elastic clamping sheet 9. Therefore, the third terminal 13 will squeeze the elastic clamping sheet 9 during the insertion process of the third terminal mounting groove 14, causing the elastic clamping sheet 9 to deform. When the third terminal 13 is completely inserted into the third terminal mounting groove 14, the elastic clamping sheet 9 releases the reaction force, causing the clamping block 17 to slide into the clamping groove 16, completing the fixation between the second terminal 8 and the third terminal 13.
