Embodiment

Below in conjunction with accompanying drawing the utility model is further described.

This as shown in Figure 1 Changeover plug combination, comprise plug pedestal 10 and changeover plug 20, plug pedestal 10 is connected with electrical equipment by power line, changeover plug 20 is provided with pin 21, institute's difference is, as shown in Figure 2, plug pedestal 10 is the housing of welding one, a side is located in power line outlet 11, plug pedestal 10 is provided with circular recess seat 12, circular recess seat 12 sidewalls are provided with clamping apparatus 13, the haptic element shell fragment 14 that is connected with power line is located in the circular recess seat 12, be used for electrically contacting with the contact head of changeover plug 20, the clamping apparatus 13 of circular recess seat 12 sets up two groups separately, is that one is connected in circular recess seat side wall upper part and establishes inwardly protruding in opposite directions boss 15, boss 15 1 ends and circular recess seat 12 bottoms are connected to form seals 16, two groups of clampings are adorned 13 and are formed bayonet socket 17, and anti-inserted in order to prevent changeover plug, the clamping apparatus 13 of both sides is not to be symmetrical arranged.

Specifically the changeover plug of several standards is elaborated again below:

With Europe rule plug is example, see Fig. 3, Fig. 4, this changeover plug 20 comprises the Connection Block 22 corresponding with circular recess seat 12, be also shown in Connection Block by figure and also be connected with pin base 23 and cylinder pin 21, Connection Block 22 bottoms are provided with outwardly directed clamp 24 corresponding to the bayonet socket 17 of circular recess seat 12, clamp 24 is aimed at bayonet sockets 17 and rotate about 90 degree and can be against sealing on 16 of a side downwards, reach the two purpose of connecting.Be provided with annular link slot 25 corresponding to haptic element shell fragment 14 in the Connection Block 22, the contact head 26 that is electrically connected with pin is located at link slot 25 two bottom sides, annular link slot 25 width at contact head 26 places are less than 3.5mm, the degree of depth is not less than 5.5mm, reach safety standard, avoid Danger Electric shock risk, be also shown in by figure, the both sides width is relatively large in addition for annular link slot 25, be that haptic element shell fragment 14 can not run into the end platform on both sides and installs smoothly during for plug-in mounting, another characteristics of present embodiment are that the contact head 26 that is connected with haptic element shell fragment 14 is integrated with cylinder pin 21, can reduce assembling element like this and save built-up time.
