Abstract
The utility model relates to a production die of a power cable connecting terminal, wherein the inner cavity of the die is adapted with the appearance of a connecting terminal, and the die is a plastic bottle blank obtained by the blow-molding. The production die is especially suitable for producing power cable connecting terminals with specification of 26/35k V. As the plastic bottle blank has simple structure and no break lines on the inner surface thereof, therefore, the produced power cable connecting terminal has no break lines, which eliminates the affects of the break lines to electric fields and electric performances.
Description
(1) technical field
The utility model relates to a kind of production mould of power cable connecting terminal.
(2) background technology
The connecting terminal of power cable, the especially connecting terminal of 35kV electric pressure, except that the annex material is had the higher requirement, its structure also must be rationally, just can satisfy the requirement as high height above sea level, thunderstorm, severe environmental conditions such as freezing.The 35kV electric pressure generally adopts prefabricated or cold-contraction type at present, and its common structure as shown in Figure 1.Its result can produce two vertical spue lines 1 that run through product external surfaces.Because spue line can cause the hydrophobicity performance of silicon rubber terminal end surface to descend, when rainy, the spue line place can produce solid stream of water but not the isolated globule.Its result causes the terminal end surface insulation to descend.
Occur a kind of technology in the market, eliminate vertical spue line by changing mould structure, as shown in Figure 2.Its spue line 2 is designed to laterally be positioned at the full skirt edge.Behind the sulfidization molding, by the direction as shown demoulding by force.But this technology still has some deficits.The one, in case Mold Making complexity precise decreasing, product is got in the demoulding all problem.The 2nd, forced stripper mechanism easily causes product because of tensile fracture.
(3) utility model content
Technical problem to be solved in the utility model be to provide a kind of simple in structure, effectively eliminate the production mould of the power cable connecting terminal of spue line influence.
The production mould of described power cable connecting terminal, the inner chamber of described mould and the profile of connecting terminal match, the plastic bottle blank of described mould for getting through blowing.
Further, described plastic bottle blank thickness is less than 0.5mm.
Further, described plastic bottle blank thickness is 0.2～0.4mm.
Plastic bottle blank of the present utility model can adopt polypropylene material usually, and the power cable connecting terminal adopts silastic material, and both do not melt mutually, thereby are convenient in demoulding.The present invention utilizes the external mold of the inner surface of plastic bottle blank as terminal, and bottle base is peeled off in the injecting glue post forming of heating at last, just forms the power cable connecting terminal product of a no vertical spue line.
The utility model is specially adapted to make 26/35kV specification power cable connecting terminal, because plastic bottle blank is simple in structure, inner surface does not have spue line, thereby the power cable connecting terminal of producing does not have spue line, has eliminated the influence of spue line to electric field and electric property.
(4) description of drawings
Fig. 1 is the structural representation of a kind of power cable connecting terminal in the prior art.
Fig. 2 is the structural representation of another kind of power cable connecting terminal in the prior art.
Fig. 3 is the structural representation of the production mould of the utility model power cable connecting terminal.
(5) embodiment
The utility model is described in further detail below in conjunction with embodiment, but protection range of the present utility model is not limited to this.
With reference to Fig. 3, a kind of production mould 3 of power cable connecting terminal, the profile of the inner chamber of described mould and connecting terminal 4 matches, the plastic bottle blank of described mould 3 for getting through blowing.
Described plastic bottle blank 3 thickness are 0.2～0.4mm.
Claims (3)
1, a kind of production mould of power cable connecting terminal, the inner chamber of described mould and the profile of connecting terminal match, and it is characterized in that: the plastic bottle blank of described mould for getting through blowing.
2, the production mould of power cable connecting terminal as claimed in claim 1 is characterized in that described plastic bottle blank thickness is less than 0.5mm.
3, the production mould of power cable connecting terminal as claimed in claim 2 is characterized in that: described plastic bottle blank thickness is 0.2～0.4mm.
