Description
Technical field
The utility model relates to a kind of flame-proof type insulating sleeve.
Background technology
Need to adopt insulating sleeve (Bushing) from flame proof (Exd) chamber to during increasing peace (Exe) chamber cabling.
With reference to figure 1 and Fig. 2, insulating sleeve of the prior art adopts compound 13 to be sealed in metal shell 11 by wire 12 usually.This metal shell 11 is a hollow-core construction, and wire 12 stretches into wherein, and then adopts compound 13 to fill, and is sealed in metal shell 11 by wire 12.
But above-mentioned insulating sleeve needs specific compound 13 to reveal between the insulating barrier and metal shell 11 of wire 12 to prevent water from dividing, and this causes the cost of insulating sleeve higher.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of flame-proof type insulating sleeve, is conducive to reducing costs, and has higher intensity, is easier to produce.
For solving the problems of the technologies described above, the utility model provides a kind of flame-proof type insulating sleeve, comprising:
The casing main body of compression molding, the material of described casing main body is insulating material, and the outer wall of described casing main body is cylindrical and have external screw thread;
Conducting strip, Integral mold is pressed in described casing main body, and described conducting strip stretches out from the two ends of described casing main body.
According to an embodiment of the present utility model, the material of described casing main body is glass reinforced thermoset plastics.
According to an embodiment of the present utility model, the material of described conducting strip is copper.
According to an embodiment of the present utility model, this flame-proof type insulating sleeve also comprises: protuberance, be fixedly connected on one end of described casing main body, the radial dimension of described protuberance is greater than the radial dimension of described casing main body, and described conducting strip stretches out through after described protuberance.
According to an embodiment of the present utility model, described protuberance and described casing main body Integral mold molded.
According to an embodiment of the present utility model, this flame-proof type insulating sleeve also comprises: flag-shaped terminals, and described flag-shaped terminals are socketed in the conducting strip that stretches out from described protuberance.
Compared with prior art, the utility model has the following advantages:
The flame-proof type insulating sleeve of the utility model embodiment adopts the casing main body of compression molding, and conducting strip Integral mold is pressed in casing main body, thus seals without the need to specific compound, is conducive to reducing costs.And such flame-proof type insulating sleeve has higher intensity, structure is simple, is easy to produce.

Embodiment
Below in conjunction with specific embodiments and the drawings, the utility model is described in further detail, but should not limit protection range of the present utility model with this.
With reference to figure 3 to Fig. 5, the flame-proof type insulating sleeve of the present embodiment comprises: casing main body 21, conducting strip 22, protuberance 23 and flag-shaped terminals 24.
Wherein, casing main body 21 is formed by compression molding, and its material can be various insulating material.Such as, the material of casing main body 21 can be ambroin, and be preferably glass reinforced thermoset plastics (GRP), it has good intensity.Certainly, casing main body 21 can also be other suitable insulating material, the plastics of such as other types.
The outer wall of casing main body 21 is cylindrical, and its outer wall has external screw thread.Preferably, this external screw thread can be formed in the lump when compression molding.This external screw thread can be spirally connected with the screw increased on the chamber wall of peace chamber, explosion-proof chamber, thus forms flame flash-back (flame path).
Conducting strip 22 Integral mold is pressed in casing main body 21.That is, when forming casing main body 21 by compression molding, conducting strip 22 being put into mould in the lump and carries out mold pressing, make to be embedded with one or more conducting strip 22 in the casing main body 21 formed.
The material of conducting strip 22 can be various electric conducting material, such as, can be copper, aluminium etc., is preferably copper.The shape of conducting strip 22 can be rectangular thin slice, but is not limited to this.
The two ends of conducting strip 22 are stretched out from the two ends of casing main body 21 respectively, and in other words, the length of conducting strip 22 is greater than the length of casing main body 21.
One end of casing main body 21 is fixedly connected with protuberance 23, and the radial dimension of this protuberance is greater than the radial dimension of casing main body 21.The profile of protuberance 23 can be polygon, such as regular hexagon.As a preferred embodiment, protuberance 23 can be one-body molded with casing main body 21, in other words, protuberance 23 and casing main body 21 can Integral mold molded, with simplified manufacturing technique.
Protuberance 23 is optional.When comprising protuberance 23, conducting strip 22 stretches out through after this protuberance 23 in the lump.
Flag-shaped terminals 24 are socketed in the conducting strip 22 that stretches out from protuberance 23 so that and wire 25 form electrical connection.
By upper, adopt the flame-proof type insulating sleeve of the present embodiment, when casing main body 21 compression molding, conducting strip 22 Integral mold is pressed in casing main body 21, thus seals without the need to re-using specific compound, is conducive to reducing costs, and structural strength is higher like this, be convenient to produce.
Although the utility model with preferred embodiment openly as above; but it is not for limiting the utility model; any those skilled in the art are not departing from spirit and scope of the present utility model; possible variation and amendment can be made; therefore, the scope that protection range of the present utility model should define with the utility model claim is as the criterion.
