DETAILED DESCRIPTION

[0022] The embodiments of the technical scheme of the utility model will be described in detail below with reference to the drawings. The following embodiments are only used to more clearly illustrate the technical scheme of the utility model, thus only as an example, and cannot limit the protection scope of the utility model.

[0023] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in the present application should be the usual meaning understood by the technical personnel in the field to which the utility model belongs.

[0024] The structure of the quick power taking socket of the utility model embodiment is as shown in Figures 1 to 3 The conductive post 1 is arranged through the insulating sleeve 2, and the conductive post 1 forms an electricity connection end at both ends to adapt to the connection with the main line. The shielding net 3 is arranged in the insulating sleeve 2 and surrounds the conductive post 1 and is insulated from the conductive post 1. The shielding net 3 can uniformly distribute the electric field, thereby significantly reducing the occurrence of the corona phenomenon. The connection piece 4 is arranged outside the shielding net 3 in the insulating sleeve 2. The connection piece 4 is connected with the shielding net 3 by abutting, welding or the like. The mounting hole 20 is arranged outside the connection piece 4 on the insulating sleeve 2. The mounting hole 20 has a mounting opening arranged on the surface of the insulating sleeve 2. The crimping plug 5 is clamped in the mounting hole 20. The crimping plug 5 is adapted to be mounted into the mounting hole 20 from the mounting opening and has the wire pressing surface 51 at the inner end of the crimping plug 5. The positioning structure 52 is arranged on the side surface of the crimping plug 5 to arrange and position the external grounding wire 6. The end of the external grounding wire 6 is crimped on the connection piece 4 through the wire pressing surface 51, thereby realizing the connection of the external grounding wire 6 with the connection piece 4 and further with the shielding net 3. In use, the external grounding wire is connected with the crimping plug 5 through the positioning structure, and when the end of the external grounding wire 6 is crimped on the connection piece 4 through the wire pressing surface 51, the external grounding wire can bear greater external tension, thereby preventing the external grounding wire 6 from slipping off, thereby ensuring the reliability of the connection. Moreover, when the grounding wire is operated, the external grounding wire 6 is connected on the crimping plug 5 and then inserted into the mounting hole 20 together, thereby realizing the grounding. The wire connection operation is convenient, and has good practicability.

[0025] As shown in Figure 2 and Figure 3 , the convex edge 53 is provided on the wire pressing surface 51, and a plurality of convex edges 53 are arranged at intervals. The convex edge 53 is used to press the end of the external grounding wire 6, so that a larger contact pressure is formed, and the external grounding wire has a "bite" effect, which can improve the pressing stability and conductivity of the external grounding wire 6.

[0026] As shown in Figure 3 , in order to ensure the fixing effect of the crimping plug-in block 5 on the external grounding wire 6, the positioning structure 52 is arranged on the side of the crimping plug-in block 5. The wiring hole has at least one bend 54, and the external lead wire is arranged in the wiring hole and forms a bending angle at the bend 54. The arrangement of the bend 54 in the wiring hole can effectively guide the running direction of the external lead wire, so that it has better positioning in the mounting hole 20 and reduces the displacement caused by tension or tension. In addition, the hole wall of the wiring hole is provided with a pressing block 521. After the external grounding wire 6 and the crimping plug-in block 5 are inserted into the mounting hole 20, the external grounding wire 6 is pressed on the side wall of the mounting hole through the pressing block 521, so as to further enhance the reliability of the fixation of the external grounding wire 6. As a preferred solution, the wiring hole is provided with an S-shaped structure, which has at least two bends 54.

[0027] As shown in Figure 2 and Figure 3 , the inner end of the crimping plug-in block 5 is provided with a through hole 55 near the wire pressing surface 51. The through hole 55 penetrates the crimping plug-in block 5, and the cross-sectional shape of the through hole 55 is long strip-shaped. Through the arrangement of the through hole 55, the inner end of the crimping plug-in block 5 has a certain elasticity. When the crimping plug-in block 5 is inserted into the mounting hole and presses the external grounding wire 6, the crimping plug-in block 5 can be deformed through the through hole 55, so as to effectively improve the cooperation precision between the crimping plug-in block 5 and the mounting hole. This design not only enhances the stability of the crimping plug-in block 5, but also ensures the reliability and durability of the crimping plug-in block 5 in use, thereby improving the overall connection effect.

[0028] In combination with Figure 1 and Figure 2As shown, there is a protruding portion 21 protruding outward on the outside of the insulating sleeve 2. The setting of the protruding portion 21 can enhance the diameter of the corresponding part of the insulating sleeve 2, and then the mounting hole 20 is set on the protruding portion 21, which can reduce the impact on the strength of the insulating sleeve 2. The depth direction of the mounting hole 20 is perpendicular to the axial direction of the conductive column 1; further, in the axial direction of the conductive column 1, both ends of the shielding net 3 have outwardly curled edges 31, and one end of the protruding portion 21 is provided with a mounting surface 22 perpendicular to the axial direction of the conductive column 1. When the quick power socket is fixed to the through-hole of the distribution cabinet, one end of the quick power socket is passed through the through-hole and is attached to the corresponding side of the distribution cabinet through the mounting surface 22. Then, the quick power socket is fixed to the distribution cabinet, which can enhance the reliability of the fixation of the quick power socket.

[0029] In order to reliably fix the crimping block 5 in the mounting hole, a latch position 23 is provided on the inner wall of the mounting hole 20 near the mounting opening, and a latch position 2 56 is provided on the side wall of the crimping block 5. The crimping block 5 is installed into the mounting hole 20 through the mounting opening, and the crimping block 5 is fixed in the mounting hole 20 by engaging the latch position 1 23 with the latch position 2 56. This can enhance the holding force of the crimping block 5 in the mounting hole, thereby preventing the crimping block 5 from loosening. One of the latch position 1 23 and the latch position 2 56 is a card platform, and the other is a card slot. The effective cooperation between the card platform and the card slot ensures the positioning effect of the crimping block 5.

[0030] In order to be able to remove the grounding wire from the quick power socket when necessary, an elastic handle 57 is provided on the side of the crimping plug 5, and the first latch 23 is provided on the elastic handle 57. When the grounding wire needs to be removed, the elastic handle 57 is pressed to deform it, thereby separating the first latch 23 from the second latch 56, so that the crimping plug 5 can be pulled out of the mounting hole, ensuring the simplicity and efficiency of operation.

[0031] like Figure 1 As shown, in order to increase the creepage distance and enhance the insulation performance, a plurality of annular flanges 24 are arranged on the outer wall of the insulating sleeve 2 at axial intervals, and annular grooves 25 are formed between adjacent annular flanges 24. The outer periphery of the annular flange 24 and the inner periphery of the annular groove 25 are both arc transitions; the arrangement of the annular flange 24 and the annular groove 25 effectively increases the surface distance of the electrical insulation, thereby reducing the risk of arcing or breakdown; and the arc transition design helps to improve the overall mechanical strength of the insulating sleeve 2 and improve its anti-pollution ability.

[0032] Obviously, the above embodiments of the present application are merely examples for clearly illustrating the present application, and are not intended to limit the implementation manners of the present application. For those skilled in the art, other different forms of changes or variations can be made on the basis of the above description. Here, it is not necessary and impossible to enumerate all the implementation manners. The obvious changes or variations extended from the essential spirit of the present application still belong to the protection scope of the present application.
