Be further to disclose concrete technology contents of the present utility model, below in conjunction with embodiment and accompanying drawing is described in detail the utility model as after, wherein:
Fig. 1 is the three-dimensional exploded view of the utility model diverter switch;
Fig. 2 shows off-state for the profile of the utility model group after upright;
Fig. 3 shows conducting state for the profile of the utility model group after upright.
Embodiment
As shown in Figure 1, basically, the utility model is to connect utmost point device 2, a part 3, one brakes 4 that are coupling by a housing 1,, and a coating member 5 combines.
Wherein, housing 1 is a hollow base frame, and its bottom surface is provided with hole, the two poles of the earth 11 and 12 relatively, for connecing the intercalation and the location of utmost point device 2, apical margin is then established a shell frame 13 to evagination, when inserting the default hole of electrical appliance, with as backstop, and for after the usefulness of coating member 5 coatings chatted.In addition, the left and right sides outer wall of housing 1 is provided with a bow type elasticity relatively and buckles 14, its central kink upper and lower is opened a button line section 141 and a flat segments 142, so that when embedding the default hole of electrical appliance, provide guidance function by flat segments 142, form the snapping locating effect by button line section 141 with its peritreme in addition.And creative feature of the present utility model is, housing 1 inwall periphery is provided with a supporting member 15, and it is to chat bridging and combining of the part 3 that is coupling after supplying, as shown in the figure, this support structure 15 be in housing 1 two-phase each vertically stretches out one section dagger 151 to the inwall both sides, its end face extends a plug tenon 152 in addition.
Connect utmost point device 2 for known, it is fixedly to connect the utmost point 21 by one to be intercalated in a utmost point hole 11, another support connects 22 of the utmost points and is intercalated in another utmost point hole 12, one arc pole piece 23 then laterally is cross-placed on to support and connects in the notch 221 of the utmost point 22,231 utmost point tenons 222 with notch 221 both sides of two-phase docking port in the middle of it engage, making arc connect the utmost point 23 connects on the utmost point 22 in support and can do lever motion, make its movable contact 232 optionally with fixed contact 211 contact that fixedly connects the utmost point 21 tops or separate, and then form the conducting or the cut-out of power supply.
The part 3 that is coupling is to be a lamellar body, and is set up on the supporting member 15, and film perforation 31 is opened in for example corresponding each plug tenon 152 position, passes through and in conjunction with it, the part 3 that is coupling firmly is cross-placed on each dagger 151 for it.These part 3 central authorities that are coupling open a bar hole 32, chat poke rod 44 after supplying and pass through, and hang down separately and establishes a sheet 33 in its both sides, and the prominent pivot 331 of establishing of side direction, for being coupling with brake 4, make it be able to reverse about above the part 3 that is coupling.These pivot 331 tops have the edge of cutting sth. askew 332, in order to brake 4 sockets.In addition, this clamping piece 4 is unlikely when switching excessively to move down in order to make, and is with, a prominent separately left and right backstop 34 and 35 of establishing of these part 3 left and right sides that are coupling, and ends limit when pushing as brake 4.
Brake 4 is to be a support body, its end face central authorities tool one arc concave surface 41, and in order to controlling of finger, and corresponding two pivots 331 of forward and backward sidewall are opened axis hole 42 separately, so that be coupling for both, in order to the operation of pushing.The downward projection one hollow roofbolt 43 of these brake 3 bottom center, it is for a telescopic poke rod 44 ccontaining and location, for example with an elastomer 45, be located between roofbolt 43 and the poke rod 44 such as spring, make this poke rod 44 connect the utmost point 23 with this arc constantly and contact, so that forming power supply breaks/logical control.
Coating member 5 is by soft high molecular weight plastic material, the cap body made of PVC for example, and it is for from bottom to top being some step shape cap bodies of convergent.Creative feature of the present utility model is, this brake 4 is imbedded its top arc concave surface 41 in the mould behind ejection formation again, and row penetrates this coating member 5 again, making its arc concave surface 41 is that the inwall that is incorporated into coating member 5 top arc recess 51 is asked, is combined as a whole according to this.In addition, these coating member 5 base part seat rank 52 root edges extend internally and one connect edge 521, so that be socketed on aforesaid shell frame 13, make whole coating member 5 with housing 1 top seal, form dustproof and waterproof effect according to this.Especially, the configuration design of this coating member 5 becomes the advantage of step shape cap body to be the telescopic resilience that can provide preferable, with avoid repetitiousness operation may cause the facts of breaking.
See also Fig. 2 and Fig. 3, the utility model is when practical operation, only need push covering piece 5, the brake 4 that can modern be combined as a whole with it is a fulcrum with the part 3 that is coupling, thereby the poke rod 44 that makes its below connects the utmost point 23 surfaces along arc and moves, the movable contact 232 of its ora terminalis is optionally contacted or tripping with the fixed contact 211 that fixedly connects the utmost point 21, make power turn-on or cut-out.Coating member 5 makes unlikely housing 1 bottom that enters of dust and aqueous vapor then with housing 1 open top complete closed, and influence connects the normal operation of utmost point device 2.Into person is arranged especially, because this coating member 5 has better elastic, and brake 4 is when repeatable operation, and its two ora terminalis is to offset as the limit of ending of pushing with left and right backstop 34 and 35, and reason does not excessively move down, and the facts generation that causes coating member 5 fractures or break.Especially, the utility model housing apical margin is because of need not to be provided with known two relative shaft-jointed holes, can avoid dust or liquid to pass through shaft-jointed hole fully, and enter shortcoming in the housing, and then the useful life of increase diverter switch, and having the demand of dustproof and waterproof concurrently, really is a ware big good structure not seen before.
The content that the utility model disclosed is a kind of of preferred embodiment, the change of every part or modification and come from technological thought of the present utility model and be have the knack of this technology the people was easy to know by inference, all do not take off patent right category of the present utility model.
