Description

A kind of Plug preventing looseness socket

Technical field

The utility model relates to the connected structure of a kind of plugs and sockets in the appliance field.

Background technology

At present, domestic technology plugs and sockets kind open and launch is more, structurally, they mainly are the dynamic connections of having adopted between plug pin and the socket resilient clip, realizes mutual grafting and separates.But, this kind syndeton is in the middle of use, owing to the socket resilient clip exists that chucking power is less than normal, relative reason such as level and smooth with plug pin surface is difficult to restore to the original state after the plastic deformation, cause between pin and the resilient clip, the loose contact even the phenomenon that gets loose very easily occur, thereby have influence on the normal use of plugs and sockets.Therefore, such technology still exists the space that needs innovation.

Summary of the invention

The purpose of this utility model is exactly for solving the deficiency of above-mentioned background technology, under the prerequisite that satisfies national plugs and sockets current techique standard, by improving the shape and the structural shape of plug pin and socket resilient clip, thereby provide a kind of functional reliability higher, and the plugs and sockets that is difficult for getting loose.

The purpose of this utility model is to realize like this, a kind of Plug preventing looseness socket, be on the cylinder of existing at least one pin of plug, increase and be provided with one or more shapes suitable projection, breach or groove, and with the corresponding existing socket resilient clip of this projection, breach or groove or its mount pad base on, increase and to be provided with the intermeshing modeling structure of described projection, breach or groove shapes.

With plug insertion socket, under the elastic reaction of socket resilient clip, this modeling structure can either engaging lock stops projection, breach or the groove on the plug pin, realize anti-loose function of the present utility model, otherwise pin can pull the plug out of the socket firmly suitably again.

The utility model is compared with background technology, not only can satisfy under the GB requirement prerequisite, creatively solved plugs and sockets and in the middle of use, be easy to generate the problem that gets loose, and can avoid getting loose accident and the economic loss and the safety utilization of electric power problem that cause by generation.

Embodiment

In conjunction with the accompanying drawings the utility model is further described below by embodiment:

01. straight pin, 02. annular recess, 03. socket, 04. conductor wire, 05. resilient clip, 06. breach, 07. protruding 08. socket, 09. conductor wire, 10. flat pin 11. pits 12. protruding 13. plug body, 14. resilient clips, 15. protruding moulding 16. pit moulding 17. sockets 20. pins 21. breach 22. plug body 23. resilient clips 24. spring steel wire cards 25. rubber and plastic elastic collars among the figure

As shown in Figure 1,01 among first embodiment is the straight pin of three-pin plug zero line side, near its end, is provided with annular recess 02, and the root of straight pin fixedly mounts with plug body 03 and is conducted with zero line in the conductor wire 04.The 05th, the resilient clip of Three-hole socket zero line side, to plug part cylindrical with straight pin, on barrel, longitudinally have at least one breach 06, and with the corresponding barrel of annular recess 02 insertion state place, be provided with the projection 07 that can be meshed with annular recess 02, under the effect of resilient clip 05 elastic force, projection 07 can be lived annular recess 02 by locking, realizes anti-loose function of the present utility model.Resilient clip 05 is as one of female component, is conducted with socket 08 fixed installation and with zero line in the conductor wire 09.

As shown in Figure 2, among second embodiment 10 is flat pins that GB bipod or three-pin plug are adopted, its outward appearance is a cuboid, appropriate location at least one flat plug body, be shaped on suitable pit 11 of one or more shapes or projection 12, the root of flat pin 10 and plug body 13 fixedly mount and are conducted with conductor wire 04.The 14th, be fixedly mounted on the socket seat base, be used for the resilient clip of pegging graft with flat pin 10 realization activities, its shape is on the architecture basics of existing known socket resilient clip, when socket inserts state and the pit 11 or protruding 12 corresponding sections that are shaped on the flat plug body, increase be provided with can with pit 11 or projection 12 protruding moulding 15 that is meshed or pit moulding 16, under the effect of resilient clip 14 elastic forces, projection moulding 15 or pit moulding 16 can be lived pit 11 or projection 12 by locking, realize anti-loose function of the present utility model.Resilient clip 14 is conducted with socket 17 fixed installations and with conductor wire 09 as one of female component.

As shown in Figure 3, among the 3rd embodiment 20 is pins that GB bipod or three-pin plug are adopted, its outward appearance is a cylindrical body, on at least one plug body by tip position, be shaped on the suitable breach 21 of one or more shapes, the root of pin 20 and plug body 22 fixedly mount and are conducted with conductor wire 04.The 23rd, be fixedly mounted on the socket seat base, be conducted with conductor wire 09, be used for resilient clip with pin 20 realization activities grafting, its shape is identical with the structure of existing known socket resilient clip, in the pedestal under resilient clip 23, setting-in is provided with flat spring steel wire card 24 or the annular rubber and plastic elastic collar 25 with elasticity folding function, when plug insertion socket, pin 20 struts and passes resilient clip 23, its breach 21 can with under spring steel wire card or rubber and plastic elastic collar realize dynamically being meshed, thereby under the effect of spring steel wire card 24 or rubber and plastic elastic collar 25 elastic forces, locking is lived breach 21, realizes anti-loose function of the present utility model.
