[0026] As Figures 1 to 7As shown, the plug pin mutual restraint conversion socket provided by the embodiment includes a shell 1, an inner frame 2 located inside the shell 1, a first power plug pin 3, a second power plug pin 4 and a third power plug pin 5. The first power plug pin 3 and the third power plug pin 5 are respectively slidably mounted on the inner frame 2 or the shell 1. The first power plug pin 3 and the third power plug pin 4 are located at two ends of the inner frame 2. The second power plug pin 4 is hingedly mounted on the inner frame 2. The shell 1 is provided with a avoiding opening 6 at a position corresponding to the first power plug pin 3, the second power plug pin 4 and the third power plug pin 5. The shell 1 is provided with a plug hole 7 at an end opposite to the end provided with the avoiding opening 6. The shell 1 is provided with a conductive plug sleeve 8 inside the plug hole 7. The first power plug pin 3 and the third power plug pin 5 are both provided with a push seat 9. The push seat 9 is provided with a push head 10 located outside the shell 1. The inner frame 2 is provided with a circuit board 11 and a sliding groove 12 located at an end opposite to the end provided with the second power plug pin 4. The sliding groove 12 is limitedly provided with a first interference piece 13 and a second interference piece 14, so that the first interference piece 13 and the second interference piece 14 can only move in a certain range. The component for realizing the limitation can be a limiting block, a limiting column or the like. The first interference piece 13 and the second interference piece 14 are provided with a spring 15 therebetween. Under the action of the spring 15, the two ends of the first interference piece 13 and the second interference piece 14 both extend out of the sliding groove 12 and are located in the track route pushed by the first power plug pin 3 and the third power plug pin 5. The two ends of the first interference piece 13 and the second interference piece 14 are both provided with a guide inclined surface 16. The first interference piece 13 and the second interference piece 14 are both provided with a barb 17. The second power plug pin 4 is provided with a limiting protrusion 18 and a socket 19 for abutting with the barb 17. When the second power plug pin 4 is not rotated out, the socket 19 directly faces the barb 17. After the second power plug pin 4 is rotated out, the limiting protrusion 18 abuts against the edge end of the second interference piece 14. The end face of the second power plug pin 4 abuts against the barb 17 of the first interference piece 13.

[0027] In the embodiment, two interference pieces are arranged in a sliding groove 12. The spring 15 is combined to make the two interference pieces have a elastic interval for returning. Thus, the first power plug pin 3 and the third power plug pin 5 can be pushed out. According to the rotation and return of the second power plug pin 4, the returning of the interference pieces is inhibited or the inhibition of the returning of the interference pieces is released. After the first power plug pin 3 and the third power plug pin 5 are pushed out or pushed back, the interference pieces inhibit the pushing out of the first power plug pin 3 and the third power plug pin 5. The whole can achieve the mutual restraint effect.

[0028] The specific mutual restraint is as follows:

[0029] In the default state, the first and third electrical contact pins 3 and 5 are in the state of not being pushed out, and the second electrical contact pin 4 is in the state of not being rotated out. In this state, the first and second interference pieces 13 and 14 are kept in a dynamic balance under the action of the spring 15, and the two ends of the first and second interference pieces 13 and 14 are respectively placed in the trajectory of the first and third electrical contact pins 3 and 5 to be pushed out, and the end surface of the guide inclined surface 16 is opposite to the pushing seat 9 of the first and third electrical contact pins 3 and 5. When the first electrical contact pin 3 needs to be pushed out, the force is applied to the pushing head 10, and the first electrical contact pin 3 can be gradually pushed out. When the pushing seat 9 of the first electrical contact pin 3 touches the guide inclined surface 16 of the first interference piece 13, the first interference piece 13 is gradually pushed to the other end of the sliding groove 12, and the second interference piece 14 is also moved. At this time, the barb 17 of the first interference piece 13 is inserted into the socket 19 of the second electrical contact pin 4, the guide inclined surface 16 of the second interference piece 14 is offset from the side of the pushing seat 9 of the third electrical contact pin 5, and the main surface of the second interference piece 14 is opposite. In this way, after the first electrical contact pin 3 is pushed out, the first interference piece 13 is always in contact with the side of the pushing seat 9 of the first electrical contact pin 3 under the action of the spring 15, the barb 17 is inserted into the socket 19, the second electrical contact pin 4 cannot be rotated, and the third electrical contact pin 5 cannot be successfully pushed out. In the default state, when the third electrical contact pin 5 is pushed, the principle is the same as that of the first electrical contact pin 3. Specifically, the second interference piece 14 is pushed to one end, and the first interference piece 13 is also moved. At this time, the barb 17 of the second interference piece 14 is inserted into the other socket 19, the guide inclined surface 16 of the first interference piece 13 is offset from the side of the pushing seat 9, the second electrical contact pin 4 cannot be rotated, and the first electrical contact pin 3 cannot be successfully pushed out. In the default state, when the second electrical contact pin 4 is rotated out, after the second electrical contact pin 4 is rotated in place, the end surface of the second electrical contact pin 4 is in contact with the barb 17 of the first interference piece 13, and the limiting lug 18 of the second electrical contact pin 4 is in contact with the edge end of the second interference piece 14. In this way, the first and second interference pieces 13 and 14 cannot be returned, and the first and third electrical contact pins 3 and 5 cannot be successfully pushed out.

[0030] Meanwhile, the inner frame 2 is fixedly installed with at least two conductive sheets 20 that are staggered relative to the end face provided with the sliding groove 12, and the two ends of each conductive sheet 20 correspond to the track routes of the first and third electrically-conductive pins 3 and 5, respectively, after the pins of the first and third electrically-conductive pins 3 and 5 are pushed out of the avoiding opening 6, the conductive parts 21 of the first and third electrically-conductive pins 3 and 5 will form contact with the conductive sheet 20, and the end face of the conductive sheet 20 is provided with an inwardly-bent contact surface 22 at the second electrically-conductive pin 4, after the pin of the second electrically-conductive pin 4 is rotated out of the avoiding opening 6, the conductive part 21 of the second electrically-conductive pin 4 will be in contact with the contact surface 22 of the conductive sheet 20, and the contact is achieved by the elastic top contact, which not only can keep the close contact with the second electrically-conductive pin 4, but also can keep the second electrically-conductive pin 4 in the state of being rotated up.

[0031] Further, the inner frame 2 of the embodiment can be detachably installed in the shell 1, for example, by screws. When all the internal components are installed on the inner frame 2, the detachable installation form can make the internal components exist in the form of a single assembly module, which is convenient for subsequent maintenance and replacement, and can also facilitate the single sale of the assembly module in the later period.

[0032] Further, in order to better have a certain stable force after the second electrically-conductive pin 4 is rotated up, the conductive sheet 20 of the embodiment is provided with an arch part 23 at the contact surface 22, so that when contact occurs, the arch part 23 can also temporarily limit the second electrically-conductive pin 4 from retreating.

[0033] Further, for the installation mode of the pushing seat 9, specifically, the side surface of the pushing seat 9 is provided with a sliding opening 24, and the inner wall of the shell 1 or the inner frame 2 is provided with a sliding rail 25, the sliding opening 24 is matched with the sliding rail 25, and the sliding installation of the first and third electrically-conductive pins 3 and 5 is satisfied.

[0034] Further, in order to facilitate the smoothness of the pushing seat 9 when vertically pushing the guide inclined surface 16, the top edge of the pushing seat 9 is provided with a chamfered surface, so that when pushing, the occurrence of jamming can be reduced.

[0035] Further, in order to facilitate the second electrically-conductive pin 4 to be rotated up, the shell 1 of the embodiment is provided with a finger position 26 at the second electrically-conductive pin 4, the finger position 26 is communicated with the avoiding opening 6 at the second electrically-conductive pin 4, and the local part of the second electrically-conductive pin 4 is placed in the finger position 4, so that the user can better hold the second electrically-conductive pin 4.
