Abstract
The utility model relates to an explosion-proof wire passing device for electrical connection from the main cavity of explosion-proof electric equipment to a wire connection cavity. The explosion-proof wire passing device is characterized in that the explosion-proof wire passing device is provided with a casing with a flange plate, the inner hole of the casing is provided with conducting wires and is filled with adhesive, and the two end faces of the casing are provided with guard sheets for the conducting wires to pass. The utility model has the advantages of simple structure, low cost and easy operation, and the actual measurement of samples conforms to the technical requirements of GB3836-83. The explosion-proof wire passing device is installed on the explosion-proof electric equipment, which has small space occupation, and solves the problems that a plurality of connecting lines can not solve. The utility model provides a novel wire passing device for the explosion-proof electric equipment to decrease dimension, reduce weight, and ensure explosion-proof performance.
Description
The utility model relates to a kind of flame proof wire passing device that is electrically connected that is used for the electrical apparatus for explosive atmospheres main cavity to wire connection cavity.
In known technology, the method for attachment of every electrical apparatus for explosive atmospheres from the main cavity to the wire connection cavity must be with the method for binding post, and this binding post surface is to be that a metallic stud constitutes by one deck thermoset plastics in the middle of it.Double-screw bolt plays the lead interconnect function of main chamber and wire connection cavity.Its weak point is that the binding post outer surface is explosion-proof, and specification requirement is higher, and therefore when shaping, percent defective is higher; Because thermoset plastics generally adopts melamino-formaldehyde fiberglass plastic or phenolic plastics, and these thermoset plasticses are relatively poor to the adaptability of environmental condition, so cause explosion-proof poor reliability; Binding post can only connect and requires to have certain electric clearance between a lead and the adjacent terminal, make that binding post take up space is with regard to corresponding increasing in the equipment, especially more outstanding under the more situation of connection lead, therefore make the overall dimension of equipment increase, weight strengthens, even can therefore make entire equipment to realize.
The purpose of this utility model is to overcome the known technology weak point a kind of flame proof wire passing device is provided.
The utility model is realized by following measure:
Structure of the present utility model is the overcoat with ring flange, and the hole is equipped with and is parallel to each other lead also separated by a distance, that stretch out at its two ends and is perfused with adhesive within it, and the both ends of the surface of overcoat are equipped with the catch that lead is passed.
Lead of the present utility model can be the lead of plastics (rubber) sheath.
The employed adhesive of the utility model is commercially available CH-31 adhesive.
Binding post contrast in the utility model and the known technology, its advantage is: simple in structure, processing technology is good, therefore cheap, easy enforcement; Safe and reliable, actual measurement reaches the regulation of national electrical apparatus for explosive atmospheres standard (GB3836-83) through sample; The utility model is installed on the electrical apparatus for explosive atmospheres, and it is little to occupy the space, has solved the insurmountable difficult problem of multi-link line, for electrical apparatus for explosive atmospheres reduces overall dimension, weight reduction, guarantees that explosion-proof performance provides reliable assurance.
Description of drawings:
Fig. 1 is an embodiment schematic diagram of the present utility model;
Fig. 2 is that the utility model is installed in the schematic diagram on the electrical apparatus for explosive atmospheres housing.
Below in conjunction with accompanying drawing the utility model embodiment is described in further detail:
The structure of the embodiment that the utility model provides is such: the overcoat 3 with ring flange, be equipped with in its endoporus be parallel to each other and guarantee a determining deviation, two ends is stretched out plastic sheath lead 1, the space, hole is perfused with commercially available CH-31 adhesive 4 within it, is equipped with in the both ends of the surface of overcoat and seals catch 2 usefulness and that lead is passed.Size of the present utility model and quantity are (the seeing attached list) that wire head number that needs according to the overall dimension of electrical apparatus for explosive atmospheres (as fire-proof motor or explosion-proof control cabinet) and this equipment and technology and the lead of selecting for use are decided.Embodiment can find out from table, and electrical apparatus for explosive atmospheres has used the utility model to solve multi-link line and used the insurmountable difficult problem of binding post.The utility model installation method is: be packed in the utility model on the next door 5 of the main chamber of electrical apparatus for explosive atmospheres and wire connection cavity by screw 6, the lead of one end can be connected with the electric elements (or motor lead-out wire) in the main chamber, and other end lead is connected on the interior binding post of wire connection cavity.
