Abstract
The utility model relates to an electric apparatus connecting wire-over group for mutually connecting an anti-explosive cavity and a non anti-explosive cavity as well as a material safety circuit and a nor material safety circuit in mine machinery. For obtaining anti-explosive and fire retardation purposes, a wire insulation skin in a wire-over casing is stripped into a gap in which glue is injected, which obtains the once seal of conducting wires; then, burning and filling sealing glue is filled in the casing to seal, which enables the inner and outer surfaces of the wire-over group to have fire retardation. The wire-over group with the sealed structure reliably solves the safety problem that the anti-explosive cavity and the non anti-explosive cavity as well as the material safety circuit and the non material safety circuit are mutually connected in mine machinery.
Description
The utility model be explosion-proof chamber and non-blast chamber in the mine equipment, intrinsically safe circuit with non-circuit between electrical equipment mutually safety is connected the fire-retardant mistake of a kind of sealed explosion-proof line group of usefulness.
For reaching safe purpose of connecting, the existing line group structure of using of crossing is: the lead seal section of crossing in the line group is peelled off 5～10mm insulated hull, makes copper cash exposed.Be one with the exposed copper cash melting welding of multiply again, pour into the sealing glue at last.The line group excessively of this structure diminishes the net sectional area of lead, and explosion-proof in addition fire-retardant safety and reliability are lower.
Task of the present utility model is to provide the safety after a kind of improve to cross the line group, and it can improve explosion-proof fire-retardant security reliability simultaneously under the constant situation of sectional area of wire.
Task of the present utility model is finished as follows:
At first will cross the wire insulation peeling strip off in the line group, and glue be poured between the insulated hull and metal of lead, make lead reach the once safety sealing.For making the casting glue in the line group not only reach sealing but also can make it fire-retardant, earlier the strong glue of bonding force is applied on the shell inner surface conductive line surfaces interior with being loaded on housing, and lead strip off section is immersed in the strong glue of bonding force, and then fire-retardant glue filled housing, this structure sealed the wire stylet of line and interior outer face fully, the whole line group of crossing not only seals but also fire-retardant, can reach explosion-proof fire-retardant safety effect reliably.
Below with reference to accompanying drawing the utility model is described in further detail.
Fig. 1 is a structure chart of the present utility model.
Fig. 2 is the cut-away view behind the utility model lead encapsulating.
Earlier lead (1) insulated hull (7) stripping is opened a gap with reference to Fig. 1, glue (5) is poured into respectively between the insulated hull (7) and metal-cored (8) at lead (1) two ends by breach, make lead (1) reach disposable sealing (seeing shown in Figure 2) fully.A fire-retardant spacer (6) is equipped with in the housing lower end, be processed with many wire through-holes as required, after lead (1) is in its middle shell (3), pour into housing (3) with the strong glue of bonding force (5), wire insulation skin (7) strip off place all is immersed in the strong glue of bonding force (5), remainder and lead (1) also adopt the strong glue of bonding force (5) to smear processing in housing (3) chamber, fill housing (3) upper end lead (1) above then fire-proof potting compound liquid (4) being covered and draw from the hole of last spacer (2), wire guide is corresponding one by one with the hole on the fire-retardant spacer (6).Last spacer (2) is installed in housing (1) mouthful place, uses fire-proof potting compound liquid (4) to pour into spacer (2) at last again and upward mouth is sealed fully.
The line group excessively of above structure can reach sealing fully under the situation that does not change the lead effective cross-section, fire-retardant, explosion-proof purpose, thus improved the safety and reliability of crossing the line group.
Claims (3)
1, one by housing (3) lead (1), the fire-retardant line group of crossing of the sealed explosion-proof that fire-retardant spacer (6) and last spacer (2) are formed, be primarily characterized in that wire insulation skin (7) in the housing (3) goes up stripping and open a gap, sealing glue (5) pour into lead (1) two ends insulated hull (7) and metal-cored between.
2, the line group of crossing according to claim 1 is characterized in that housing (3) inside conductor (1) insulated hull (7) strip off place all is immersed in the strong glue of bonding force (5).
3, the line group of crossing according to claim 1 and 2 is characterized in that all being coated with the strong glue of one deck bonding force (5) on housing (3) inner chamber and the lead (1), and fire-proof potting compound liquid (4) covers thereon, and fills housing (3).
