Embodiment
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, Figure 2 and Figure 3: in order to improve the reliability of drawer-type switch cabinet multi-tap, reduce the temperature rise that load current produces, the utility model comprises static contact component 2, and described static contact component 2 comprises the first contact opening 5 and second contact opening 6 corresponding with described the first contact opening 5; The second contact opening 6 of described static contact component 2 stretches in insulation protective hood 1 through after insulated support 3, and the second contact opening 6 is connected with the insertion opening 7 on insulation protective hood 1; The opening degree α of described insertion opening 7 is 20 ° ~ 40 °.
Particularly, the first contact opening 5 of static contact component 2 is for inserting the bus of power switch cabinet, the second contact opening 6 is moving contact for inserting drawer plug, the second contact opening 6 stretches in insulation protective hood 1 through after insulated support 3, after being connected with insertion opening 7, for inserting drawer plug, be moving contact.The insertion front end 10 that described insulation protective hood 1 forms insertion opening 7 outer rings is curved, by insertion front end 10 guide effects of arc, can be conducive to insert, and in the time of avoiding inserting, tilts, and reduces the unsteadiness being caused by inclination.In the utility model embodiment, the opening degree optimum of described insertion opening 7 is 30 °.The thickness of described insulation protective hood 1 is 4.5mm, has increased the thickness of insulation protective hood 1, improves the intensity of insulation protective hood 1.
As shown in Figure 4 and Figure 5: described insulated support 3 comprises strutting piece housing 20, in described strutting piece housing 20, be provided with to support cavity 13 is installed, the outside of strutting piece housing 20 is provided with supporting and location body 17,20 of described supporting and location body 17 and strutting piece housings have pin holes 12, and described pin holes 12 allows the card base 8 on insulation protective hood 1 to set.The end of described card base 8 arranges fixture block 14, and described fixture block 14 is the type of carving.Card base 8 inserts in pin holes 12, by carving the fixture block 14 of type and coordinating of supporting and location body 17, can effectively limit the relative motion of 1 of insulated support 3 and insulation protective hood.
Described supporting and location body 17 is provided with some reinforcements 11 with the joint portion of strutting piece housing 20, is provided with some mounting grooves 18 in strutting piece housing 20.Described mounting groove 18 can mate with static contact component 2, be convenient to through after static contact component 2 with the contacting of static contact component 2.
Insulation protective hood 1 has protective cover housing, and symmetrical cell body 16 is set on protective cover housing, and one end of card base 8 is positioned at cell body 16, and fixture block 14 is positioned at the other end of card base 8.In protective cover housing, there is protective cover cavity 9, described protective cover cavity 9 can hold static contact component 2 and insulated support 3, the interior contiguous one end of inserting in opening 7 of protective cover cavity 9 arranges guide pad 15,15 of guide pads form and insert passages, are convenient to by inserting after opening 7 and being electrically connected to of the second contact opening 6.
As shown in Figure 6: described static contact component 2 comprises some fixed contact parts and the fixed contact connector 19 that described fixed contact part is linked together, and described fixed contact connector 19 is provided with reseting spring leaf 4, and described reseting spring leaf 4 is positioned at the outside of fixed contact part.Described reseting spring leaf 4 is stainless steel spring.
When three groups of static contact components 2 are arranged on after contact head insulated protective cover 1, installing insulating strutting piece 3 again, the pin holes 12 of insulated support 3 is inserted in the card base 8 of contact head insulated protective cover 1, and fix static contact component 2, four reinforcements 11 are set on insulated support 3, are mainly that insulated support 3 is under pressure when moving contact insertion above, all power concentrates on insulated support 3 and forms distortion, and the moving contact faying face inserting is reduced.In the utility model embodiment, adopt rear its strength increase of reinforcement 11, stress surface, by being transferred on reinforcement 11, reduces distortion, and contact-making surface is increased, and guarantees its contact area.The first contact opening 5 is to be inserted on cabinet bus, and the second contact opening 6 is that to leave that drawer inserts for be the opening that moving contact inserts.
Existing expert's socket is in use because the insulating case opening of socket is less, the front end that inserts position adopts right-angle structure, easily produce problem stuck while inserting, after insufficient strength distortion during insertion causes and inserts, plug is not in place, cause the problem that is subject to heating after large electric current so that device failure while inserting, for this designs the problem existing, the utility model is thickeied insulation protective hood 1, improve its intensity, insert opening 7 and be set to 20 °-40 °, preferably 30 °, the insertion front end 10 that inserts opening 7 is circular arc; Simultaneously, at insulated support 3, install a reinforcement 11 additional, can be effectively produce intensity when inserting and guarantee effect is played in distortion, after design improvement, while making to insert, not in place and inclination and fever phenomenon are effectively alleviated, not only improve the binding ability of contact, can also avoid contact in conjunction with time produce the fever phenomenon that loose contact produces.
