The utility model has the advantages of simple and reasonable structure, install the terminal on the box junction through-hole, not only saved the complicated installation link of traditional terminal, still effectually reduced the box volume. Replace the explosion-proof mud that is used for isolated external rubber gasket and intercommunication department needs between the original box junction with the sealing rubber circle, choose simultaneously for use sealing tube threaded connection to form the dual fail-safe, when guaranteeing the product flame proof performance, reduce the process and improve the installation effectiveness.
Drawings
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is a front view of the present invention.
Wherein, the device comprises a shell 1, an injection molding part 2, a conducting strip 3, a clapboard 4, a lug 5, a circular ring baffle 6, a sealing ring 7 and an arc groove 8.
Detailed Description
The invention is described in further detail below with reference to the drawings in the specification:
the utility model relates to an explosion-proof type terminal that is used for wiring between electric type box, this explosion-proof type terminal set up on the round hole passageway between two electric boxes, explosion-proof type terminal includes shell 1, injection molding 2 and ring baffle 6, shell 1 set up at 2 one ends of injection molding, and shell 1 and 2 fixed connection of injection molding, the utility model discloses in, the free end of injection molding 2 extends to its other end from the one end of round hole passageway, then sets up ring baffle 6 on the free end of injection molding 2 and fixes it, the utility model discloses in, shell 1 and injection molding 2 also can the integration set up.
The utility model discloses still cup jointed sealing washer 7 on injection molding 2, sealing washer 7 set up between ring baffle 6 and shell 1, the external diameter of sealing washer the same or slightly be greater than the internal diameter of round hole passageway with the internal diameter of round hole passageway. After the shell 1 and the annular baffle 6 are fixed, the sealing ring 7 can effectively fill the residual space, and the sealing performance is ensured.
Because the conducting strips 3 are uniformly separated according to the distance required by voltage, a plurality of partition plates 4 are arranged on two end parts of the injection molding part 2, the end parts of the injection molding part 2 are partitioned into a plurality of areas by the partition plates, and the conducting strips 3 are arranged in each area, so that the phenomenon of short circuit between the conducting strips 3 is avoided. Furthermore, the separating plates 4 are arranged opposite one another at the ends of the two injection-molded parts 2. The extension positions of the conducting strips 3 at the two ends of the injection molding piece 2 are ensured to be consistent.
The utility model discloses in, set up lug 5 on shell 1 and ring baffle 6 surfaces, lug 5 be convenient for operating personnel with the terminal screw up, set up inside circular arc recess 8 at the edge of shell 1 with ring baffle 6, set up after circular arc recess 8, when the terminal installation is accomplished, shell 1 just forms the depressed part with the inner wall of ring baffle 6 and round hole passageway, operating personnel can select to inwards fill explosion-proof mud, forms the third insurance.
