Summary of the invention
Technical problem to be solved in the utility model is the defective that overcomes prior art, provide a kind of simple in structure, can be when closing explosion-proof chamber automatic guide energize and the unexplosive electric connector with mechanical electric interlock of automatic cut-off power when opening explosion-proof chamber.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of unexplosive electric connector with mechanical electric interlock, comprise the plug body and the jack housing that link together by locking nut, the inner chamber of plug body and jack housing forms explosion-proof chamber, socket connector is installed in the jack housing, be fixed with the plug inner core in the plug body, plug connector with the socket connector coupling is installed on the plug inner core, also comprise push-button switch contact and the push-button switch that can make plug connector and outside installed part power on/off, push-button switch is installed in the bottom of plug inner core, the push-button switch contact is inserted on the plug inner core slidably, the lower end of push-button switch contact props up the button of push-button switch, is provided with the promotion induction installation with the push-button switch contacts mates in the jack housing.
Further, described promotion induction installation comprises the contact gland, is installed in the spring that the contact cover on the contact gland, the spring contact that matches with the push-button switch contact and an end prop up spring contact, and this spring fitting is in the contact cover.
After having adopted technique scheme, plug body and jack housing in conjunction with the time, press the button switch so that plug connector and the energising of outside installed part by the promotion induction installation in the jack housing, realized the effect of automatic guide energize when closing explosion-proof chamber, when plug body is transferred to jack housing, leave push-button switch owing to promoting induction installation, so that push-button switch resets, cut off being electrically connected between plug connector and the outside installed part, the effect of automatic cut-off power when having realized opening explosion-proof chamber, realized the purpose of mechanical electric interlocking, avoided simultaneously opening the phenomenon that explosion-proof chamber causes explosion accident without deenergization, play the effect of taking precautions against in possible trouble, and simple in structure.
Description of drawings
Fig. 1 is the structure cutaway view with unexplosive electric connector of mechanical electric interlock of the present utility model.
Embodiment
Content of the present utility model is easier to be expressly understood in order to make, and the below is described in further detail the utility model according to specific embodiment also by reference to the accompanying drawings,
As shown in Figure 1, a kind of unexplosive electric connector with mechanical electric interlock, comprise the plug body 2 and the jack housing 1 that link together by flameproof joint, the inner chamber of plug body 2 and jack housing 1 forms explosion-proof chamber 21, socket connector 3-1 is installed in the jack housing 1, be fixed with plug inner core 8 in the plug body 2, plug connector 3-2 with socket connector 3-1 coupling is installed on the plug inner core 8, also comprise push-button switch contact 6 and the push-button switch 7 that can make plug connector 3-2 and outside installed part power on/off, push-button switch 7 is installed in the bottom of plug inner core 8, push-button switch contact 6 is inserted on the plug inner core 8 slidably, its fit clearance also forms flameproof joint, the lower end of push-button switch contact 6 props up the button 7-1 of push-button switch 7, is provided with the promotion induction installation that cooperates with push-button switch contact 6 in the jack housing 1.The effect of automatic cut-off power when this unexplosive electric connector has been realized when closing explosion-proof chamber 21 automatic guide energize and opened explosion-proof chamber 21, realized the purpose of mechanical electric interlocking, avoided simultaneously opening the phenomenon that explosion-proof chamber causes explosion accident without deenergization, play the effect of taking precautions against in possible trouble, and simple in structure.
The end of plug body 2 and jack housing 1 all is connected with cable introducing device 13, and the junction of plug body 2 and jack housing 1 uses locking nut 12 to realize locking function.Waterproof grommet is used in the athwartship plane junction of plug body 2 and jack housing 1, guarantees its water resistance.Use simultaneously screw 14 laterally to prop up the outer step of plug body 2, in case locking nut gets loose and loses explosion-proof.
Promote induction installation and can realize by following structure its function, as shown in Figure 1, promote induction installation and comprise contact gland 10, be installed in the spring 11 that the contact cover 5 on the contact gland 10, the spring contact 4 that matches with push-button switch contact 6 and an end prop up spring contact 4, this spring 11 is installed in the contact cover 5.
