Description of drawings
Below in conjunction with drawings and Examples the utility model is described in detail, wherein:
Fig. 1 is the schematic perspective view of the utility model one embodiment;
Fig. 2 is the schematic perspective view of another embodiment of the utility model;
Fig. 3 is the schematic diagram of the utility model connector assembly housing bottom surface;
Fig. 4 is the schematic perspective view that the utility model is changed the plug base inner surface.
Embodiment
Fig. 1 is the exploded perspective structure of the utility model one embodiment.This safe and intelligent type universal conversion electric power jockey comprise a connector assembly 1, with the plug-assembly 2 of this connector assembly clamping and the power supply connecting device 3 that is connected with connector assembly 1.In this embodiment, described power supply connecting device is a power line, and the one end is electrically connected with conducting element in the connector assembly 1, and the other end is provided with the connection-peg (figure omits) that is used for connecting electrical appliance.Plug-assembly 2 comprise one group replaceable, adapt to the plug of various criterion.
The upper surface of connector assembly 1 is provided with the inserting groove 4 of left end sealing, right-end openings, and replaceable plug just is plugged in this inserting groove 4.The front end edge 5 of replaceable plug (left end limit) just in time is against the blind end wall 6 of inserting groove 4 mutually, and power line then is connected in an end of inserting groove 4 openings of connector assembly.In the present embodiment, the both lateral sides of described inserting groove 4 symmetries is respectively equipped with for replaceable plug and injects the gathering sill of extracting 7, and the middle part at gathering sill 7 edges has breach 15, also is provided with in the gathering sill of this breach right-hand member to stop projection 18.The conducting element of connector assembly 1 inside passes the bottom surface of inserting groove 4, forms elastic electrode contact 8, the 8a (consulting Fig. 4) of angular distribution.The bottom surface of described inserting groove 4 is provided with the shell fragment of a strip by blind end, the outer surface that this shell fragment extends to connector assembly 1 to the left forms a button 12, the both sides up and down of this shell fragment and the case material of button left end and connector assembly have joint-cutting and disconnect, the right-hand member of shell fragment keeps being connected with the case material of inserting groove 4 bottom surfaces, shell fragment near inserting groove 4 blind end walls 6 is provided with a raised line 13, this raised line can with front end edge 5 clampings of replaceable plug so that form the clamping of described connector assembly 1 and replaceable plug.
Openend one side of the inserting groove 4 of described connector assembly, a pin 11 input shell fragment contact jaw serial connections are provided with an electric current temperature detect switch (TDS) 20, and this temperature detect switch (TDS) is positioned at the groove within the removable cover 16, as shown in Figure 3.In a preferred embodiment of the present utility model, described electric current temperature detect switch (TDS) 20 adopts self-recovering type current temperature type switch.
Fig. 2 is another embodiment of the present utility model, and wherein said power supply connecting device is the plug that is connected with connector assembly 1, can be Eight characters circular hole plug, product word circular hole plug or IEC plug, and this plug directly is connected with making electrical appliance.This structure is specially adapted to some small-sized household electrical appliance, as notebook computer, and chargers such as digital camera.
Replaceable plug comprises: the base 9 of band bending edges, be located at the chimb 10 that can cooperate slippage with described gathering sill 7 of base two side lower parts, this chimb 10 is the chimb of forward and backward discontinuous setting, and the chimb of leading portion can be adaptive with the breach 15 of gathering sill.The inner surface of replaceable plug is provided with the groove 14 that can supply ground wire electrode contacts 8a to pass through, and the width of this groove is less than raised line 13 length (consulting Fig. 4) on the described shell fragment.Base 9 vertically be interspersed with can with the pin 11 of described electrode contacts 8, the corresponding different size standard that compresses of 8a.These pins can be any of Chinese Industrial Standards (CIS), Unite States Standard, British Standard, Australia standard or European standard or the like various criterion.
When replaceable plug inserts connector assembly 1, the breach 15 that only needs the chimb 10 of its front end to be aimed at gathering sill 7 on the connector assembly downwards inserts, push described in guide groove 7 more to the left, at this moment, the groove 14 of the inner surface of replaceable plug slips over the ground wire electrode contacts 8a on the inserting groove 4, the front end edge 5 of replaceable plug is run into the raised line 13 on inserting groove 4 shell fragments earlier, and force it downward, after replaceable plug pushes left and puts in place, above-mentioned raised line 13 return under the effect of shell fragment elastic force, and snap in replaceable plug front end edge 5 inner surfaces, like this replaceable plug 2 and connector assembly 1 are connected and fixed.When replaceable plug 2 with after connector assembly 1 is connected, the electrode contacts 8 on the connector assembly 1,8a just with replaceable plug 2 on each pin 11 corresponding contacts so that the conducting electric current, electric current is drawn by power line 3.
When needing to change the replaceable plug of different size standard, press described button 12, raised line 13 is along with downwards and break away from the front end edge 5 of replaceable plug, at this moment, can release to the right when it slides into described breach 15, be directed to the groove right-hand member stop projection 18 stop (consulting Fig. 2), can only upwards unload.This stops that projection can stop replaceable plug when the right skids off, and its front end edge causes the damage of live wire and zero wire electrode contact 8.
Certainly, also the chimb 10 of replaceable plug 2 can be made continuous shape, gap 15 not on the gathering sill 7 pushes gathering sill 7 with replaceable plug 2 from the openend of connector assembly inserting groove 4 during installation.This kind structure, the inner surface of replaceable plug will have can be for the electrode contacts 8 on the inserting groove 4, the groove that 8a passes through.
Consult Fig. 1, the utility model is connected in power line at one end of the inserting groove opening of connector assembly, after this electric power connecting device injects supply socket, if pulling power line or undue force take off this device along the downward direction of power line accidentally, because thisly firmly just in time make the front end edge of replaceable plug hold out against the blind end wall of inserting groove, promptly make connector assembly and replaceable plug against all the more tight, connector assembly may not pulled down separately, thereby solved the defective of prior art effectively, security performance improves greatly, meets the safety standard of American-European countries's electrical equipment fully.
The utlity model has following functions:
When the contact flat spring in the socket with after plug contacts, during the contact flat spring excess Temperature, the electric current temperature detect switch (TDS) automatic cut-off power of establishing in heat is transmitted to; Behind drop in temperature, the automatic plugged of electric current temperature detect switch (TDS);
When the contact flat spring in the socket with after plug contacts, because institute's connection device breaks down or during short circuit, set electric current temperature detect switch (TDS) cuts off immediately institute and connects power supply in the changeover plug main body, the pending fault processing or pull out the equipment that connects after, automatic plugged;
3. when changeover plug is connected with the use supply socket, because supply socket loose contact or socket are oversize service time, cause plug and socket loose contact, produce high temperature. When Contact Temperature reaches 135 ℃ of limiting temperatures (this temperature can be set); set electric current temperature detect switch (TDS) automatic cut-off power in the changeover plug; after Contact Temperature descended, automatic plugged had protected temperature can not continue to raise and cause the short circuit breaking out of fire.
