The connection stability requirements of the plug and socket in the electrical room are relatively high. Once the plug and socket are separated, the equipment will stop running, affecting the operation of the equipment; secondly, reinserting the plug to restore the equipment to the state before the plug and socket are separated requires operating time, which increases the operating cost. Therefore, it is very necessary to invent an electrical plug and socket. Utility Model Content

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0030] Reference Figure 1-Figure 3 , an electrical plug, including a plug body 1, which is a prior art and its shape is not limited.

[0031] Reference Figure 1-Figure 3 A locking block 2 is slidably disposed on the plug body 1 , and the locking block 2 slides up and down on the plug body 1 , that is, a locking block slide groove corresponding to the locking block 2 is disposed on the plug body 1 .

[0032] In some embodiments, reference Figure 1-Figure 3 The locking block 2 is columnar, and a positioning inclined surface 20 is provided on the top of the locking block 2.

[0033] Reference Figure 1-Figure 3 An elastic member is provided below the locking block 2 to maintain the locking block 2 extending outside the plug body 1. Preferably, the elastic member is a locking block reset spring 3, and both ends of the locking block reset spring 3 are respectively connected to the end surface of the locking block 2 and the bottom of the locking block slot.

[0034] In order to facilitate the subsequent pre-positioning of the plug body 1 , at least one limiting protrusion 10 is further provided on the outer wall of the plug body 1 . Preferably, the number of the limiting protrusions 10 is two.

[0035] A positioning member 4 is disposed on one side of the plug body 1 . The positioning member 4 includes an adjusting member 40 , an adjusting member return spring 41 and a positioning rod 42 .

[0036] Reference Figure 1-Figure 3 The adjusting member 40 is block-shaped and is provided with a resisting inclined surface 400, that is, a lower embedding groove structure is provided on the adjusting member 40, and the resisting inclined surface 400 is provided on the inner wall of the lower embedding groove structure, and an adjusting member embedding groove 11 for sliding the adjusting member 40 is provided on the plug body 1.

[0037] See also Figure 1-Figure 3 The two ends of the adjusting member return spring 41 are respectively connected to the inner side wall of the adjusting member embedding groove 11 and the side wall of the adjusting member 40 to maintain the position stability of the adjusting member 40.

[0038] Reference Figure 2 and Figure 3, the positioning rod 42 slides in the plug body 1, and one end of the positioning rod 42 is provided with a braking slope 420 that cooperates with the interfering slope 400. Through the cooperation between the braking slope 420 and the interfering slope 400, the positioning rod 42 is braked to be embedded outside the plug body 1 or inside the plug body 1 through the horizontal movement of the adjusting member 40. It should be noted that: under the action of the adjusting member return spring 41, the adjusting member 40 causes the braking slope 420 to fit with the interfering slope 400, thereby making the positioning rod 42 protrude from the plug body 1. When the adjusting member 40 is pressed inward, the positioning rod 42 falls downward under the action of gravity until the positioning rod 42 is stored in the plug body 1.

[0039] Based on the electrical plug disclosed in this embodiment, it should be noted that the locking block 2 and the positioning member 4 are arranged on the shell of the plug body 1 and will not affect the electrical connection and internal structure of the plug body 1.

[0040] This embodiment also discloses an electrical socket for installing the electrical plug disclosed in this embodiment.

[0041] Reference Figure 1-Figure 3 The electrical socket includes a positioning ring 6 arranged on the outer edge of the socket body, a moving ring 5 slides inside the positioning ring 6, a slider protrusion 51 is arranged on the outer wall of the moving ring 5, and a slider groove 61 sliding with the slider protrusion 51 is arranged on the positioning ring 6, and the slider groove 61 does not penetrate the length of the positioning ring 6, so that the moving ring 5 will not be separated from the positioning ring 6.

[0042] Reference Figure 2 and Figure 3 The inner walls of the moving ring 5 and the positioning ring 6 are respectively provided with a sliding opening 50 and a locking groove 60 corresponding to the locking block 2. The sliding opening 50 is used for the locking block 2 to extend outside the moving ring 5, and the locking groove 60 is used to cooperate with the locking block 2 to achieve locking between the plug and the positioning ring 6.

[0043] Furthermore, in order to facilitate the unlocking of the locking block 2 from the locking groove 60 and facilitate the removal of the plug, a braking protrusion 500 is provided in the sliding port 50, and a receiving inclined surface 5000 cooperating with the positioning inclined surface 20 is provided at the bottom of the braking protrusion 500, wherein the inclination direction of the receiving inclined surface 5000 and the positioning inclined surface 20 is referenced Figure 2 and Figure 3 .

[0044] Finally, in order to further ensure that the movable ring 5 will not move outward and that the locking block 2 will not arbitrarily release the lock on the locking groove 60, the outer end of the movable ring 5 is provided with a locking groove 52 corresponding to the positioning rod 42. When the positioning rod 42 is aligned with the locking groove 52, the movable ring 5 is prevented from sliding backward, thereby preventing the movable ring 5 from moving backward and releasing the lock on the locking groove 60 by the locking block 2.

[0045] Among them, the inner wall of the movable ring 5 is provided with a pre-positioning groove 53 corresponding to the limiting protrusion 10. When the limiting protrusion 10 is aligned with the pre-positioning groove 53, the locking block 2 is ensured to be aligned with the locking groove 60, which facilitates the locking block 2 to be inserted into the locking groove 60.

[0046] The functional principle of the utility model can be explained through the following operation modes:

[0047] The installation process of the plug and socket is as follows:

[0048] The plug body 1 is inserted into the positioning ring 6 to ensure that the limiting protrusion 10 is aligned with the pre-positioning groove 53. As the plug body 1 is inserted, the protruding locking block 2 is pressed against the movable ring 5 by the positioning inclined surface 20 and is received in the plug body 1. When the locking block 2 passes through the sliding opening 50 and is embedded in the locking groove 60, the locking block 2 is restricted from sliding by the locking groove 60, thereby preventing the plug body 1 from being separated from the socket body. In addition, the positioning rod 42 is located in the locking groove 52 to prevent the movable ring 5 from moving, thereby preventing the locking block 2 from being separated from the locking groove 60.

[0049] The process of unplugging the plug from the socket is as follows:

[0050] Pressing the adjusting member 40 causes the adjusting member 40 to extend into the adjusting member embedding groove 11, causing the positioning rod 42 to extend into the plug body 1 under the action of gravity. After the restriction of the positioning rod 42 on the movable ring 5 is lost, the movable ring 5 is pulled outward, causing the receiving slope 5000 to contact the positioning slope 20, causing the positioning slope 20 to drive the locking block 2 to extend into the plug body 1, thereby squeezing the spring; at this time, the locking groove 60 loses the restriction on the locking block 2, and the plug body 1 can be pulled backward from the socket.

[0051] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
