Abstract
The invention discloses an intensive anti-explosion cable leading-in device. The intensive anti-explosion cable leading-in device is characterized by comprising a cable leading-in bolt which adopts a threaded anti-explosion surface, wire separation cards A and B which are made of flame-retardant plastics, a led-in cable wire, a wiring terminal, epoxy resin for filling and sealing, an anti-sliding elastic pad, wherein the wire separation card A slides to the bottom of the bolt; the wire separation card B slides to an opening of a cavity of the bolt; the led-in cable wire penetrates through the bolt and then respectively penetrates through via holes of the wire separation cards A and B; the epoxy resin is injected into the cavity of the bolt; and the required wiring terminal is pressed against the head of the cable wire. By adoption of the intensive anti-explosion cable leading-in device, the problems of large size, complexity in installation and assembly, low practicability in a small anti-explosion cavity and the like of the conventional leading-in device due to influence of creepage distance and a safety clearance are solved. In a cable direct leading-in mode, the device is not influenced by the creepage distance and the safety clearance; by adoption of the wire separation cards, when burnt down, a line can be prevented from being short-circuited; and by filling the epoxy resin and using the threaded anti-explosion surface, the aims of insulation and anti-explosion are fulfilled, and assembly space is greatly saved.
Description
Technical field
The present invention relates to a kind of explosion-proof introducing device of intensive style, specifically is a kind of intensive explosion-proof cable introducing device of introducing for anti-explosion product inside different cavity inner cable line.
Background technology
According to the requirement of mine explosion-suppression and intrinsic safety type, the connection in explosion-proof chamber and intrinsic safety chamber need to be taked the flame proof measure, and outside line is introduced explosion-proof chamber also must take the flame proof measure; And in order to improve the fail safe of mining product; in the design of this explosion-proof chamber, usually can in an explosion-resistant enclosure, design three independently cavitys; be respectively: the explosion-proof chamber that non-intrinsically safe circuit is installed; the explosion-proof chamber of reserve battery and the intrinsic safety chamber that intrinsically safe circuit is installed are installed; these three chambeies all need take explosion precaution to introduce mutually cable; and at present the known explosion-proof wiring post of introducing for explosion-proof cable and cable introducing device owing to be subjected to the impact of creepage distance and safety clearance to exist build larger; the problems such as assembling trouble are installed, make its practicality in the small flame-proof chamber greatly limited.The present invention is the improvement to above device, makes it greatly save the space in the cavity under satisfying the situation of safety requirements, and assembling is simple, flexible.
Summary of the invention
The object of the invention is to provides a kind of intensive style explosion-proof cable introducing device at this
,Build is large, trouble etc., the greatly limited problem of practicality in the small flame-proof chamber are assembled in installation owing to the impact that is subjected to creepage distance and safety clearance exists to solve traditional introducing device.
The present invention realizes like this, construct the explosion-proof cable introducing device of a kind of intensive style, it is characterized in that: include that the cable that adopts the threaded flame-proof type face is introduced bolt, adopted separated time card A, B that flame retardant plastics makes, cable and the binding post of introducing, be used for the epoxy resin of embedding and be used for skid-resistant bullet pad; Described ply-yarn drill sheet A slips into the bolt bottom, described separated time card B slides into bolt cavity oral area, the cable of described introducing penetrates bolt, again cable is penetrated respectively the via hole of ply-yarn drill sheet A, separated time card B, described epoxy resin injection enters in the cavity of bolt, suppresses the binding post that needs at cable wire head place.
The processing method of the explosion-proof cable introducing device of a kind of intensive style of the present invention, it is characterized in that: bolt adopts the threaded flame-proof type face, the cable that needs are introduced penetrates bolt, cable is imported respectively into the via hole of separated time card A again, separated time card A is slipped into the bolt bottom, the epoxy resin injection that proportioning is good enters in the cavity of bolt, again cable is passed another separated time card B, separated time card B is slided into bolt cavity oral area, compress the epoxy resin of embedding, leave standstill to epoxy resin air-dry; After epoxy resin is air-dry, go out to suppress the binding post that needs at the end of a thread and get final product, mix skid-resistant bullet pad during assembling.
The present invention has continued to use the stainless steel bolt of threaded flame-proof type face, and the cable that needs are introduced penetrates in the bolt, and with line discrete open of two separated time cards with introducing, the epoxy resin that proportioning is good injects in the bolt cavity air-dry at last respectively.
Beneficial effect of the present invention is: build is large, trouble etc., the greatly limited problem of practicality in the small flame-proof chamber are assembled in installation owing to the impact that is subjected to creepage distance and safety clearance exists to have solved traditional introducing device.The mode that its technical characterstic has been to adopt cable directly to introduce has been avoided the impact of creepage distance and safety clearance, produce short circuit when using simultaneously the separated time card to avoid circuit to burn, the purpose of insulation and flame proof has been played in the employing of the embedding of epoxy resin and threaded flame-proof type face, has greatly saved assembly space.
