Description
The present invention relates to a kind of circuit connector, special (though not ad hoc) is a kind of circuit connector that is used in mine and the quarry.
In known devices, a circuit connector comprises a metal shell; End at shell has a plastic head, and electric connection is fixed therein; Another end at shell has an opening, and the insulated conductor of a cable is by opening, and lead invests on the joint; And one seal cover be used for the wire armouring of cable is clamped in the outer surface of shell; After connector device prepared, the aperture feeding resin or the compound that pass on the shell filled up the middle space of connector, and the sclerosis back forms a weather proof connector.
This known devices has following shortcoming: metal shell makes the connector heaviness and makes costliness, the seal cover that generally shielding is not provided and must adopts different size for the cable of various sizes between the joint.
The objective of the invention is to overcome these shortcomings.
According to the present invention, circuit connector is mounted in an end of the armoured cable of the lead with a plurality of each self-shileding.This connector comprises a ferrule of a formation connector front; At least two electrical insulating material pipes that are fixed in the ferrule; Lay an electric connection in every pipe, this connector links to each other with the end portion of the lead separately that cable shield has been clipped; Clamping device, electrically and be mechanically connected to ferrule clamping cables wire armouring; One foraminate (foramenous) metal earth shield is round the end portion of pipe and said each lead; And an animi resin insulating compound, fill up the space in the middle of the shielding, embed shielding and form the surface, outside of connector.
Insulating compound is preferably based on epoxy resin, poly-mephenesin Carbamate or acrylic acid casting resin (acrylic casting resin).
Lead preferably is wound on the joint; One insulating sleeve is preferably round the interface of each coiling; Sleeve pipe preferably adopts the heat shrinkable plastics.On the other hand, sleeve pipe can be made of the rolling insulating material.
Mat adopts a ferrule, and the part of head can be designed to extend between the joint, thereby joint is shielded each other.Ferrule is single type preferably.Perhaps, head can be a two-piece type, and forward part forms the front of connector, and the rear section forms the shielding fin between the joint.
Wire armouring clamping device preferably is installed at least one the metal supporting pillar that invests ferrule.Clamping device preferably has one or several trip bolts, in order to each conductor shielding mechanically and electrically is connected to clamping device.
Preferably there are three supporting pillars to invest ferrule.Supporting pillar preferably is screwed to ferrule threadably.When ferrule was two-piece type, preferably a threaded portion of at least one supporting pillar was passed in the aperture in the rear section, and is screwed to forward part threadably, thereby two partial fixings together.
In addition, wire armouring clamping device can be installed on the metallic shield fin, and it is to be again alternate barrier between the lead between the joint that this fin extends to form from ferrule.Like this, wire armouring clamping device can comprise at least two beckets, and lead passes the center of ring and mistake, and ring is to be close together to clamp wire.For example, the becket of two separation can be fixed with nut, and those nuts are screwed on the thread socket or stud that extends from the shielding fin, and perhaps, a ring can be integrally to form with the shielding fin, and above at least one eseparation ring is fastened to screw.
The most handy a kind of suitable adhesive glue of splice insulation pipe is in ferrule.On the other hand, when ferrule is two-piece type,, mat keeps in position but pressing from both sides the part of each pipe between two parts that are fastened on ferrule.Pipe preferably adopts a kind of polyester dough moulding material (thermost polyester dough moulded material) of thermosetting to make.
Foraminate metal earth shield preferably is connected to ferrule and wire armouring clamping device with clamping ring.Shielding can be prefabricated metal (for example brass) grid or (if structure is filled with resin) thin metal (for example copper) sheet.
The mould of any adequate types can be used in the manufacture process of the present invention.Mould preferably two-piece type and make by cast iron, tool steel, stainless steel or aluminium alloy (utilization rate and the existing storehouse condition that depend on expection).For preventing that mould and insulating compound from adhering between the two, (for example polytetrafluoroethylene) handled with a kind of permanent release coating in the surface, inside of mould, but, substitute as a kind of, can any suitable greasiness compound, when mould uses at every turn, be coated on the surface, inside of mould, this greasiness compound (for example silicone grease) is can be not miscible with liquid resin.Another possibility is to adopt the mould of being made by a kind of firm heat resistant plastice (for example polytetrafluoroethylene) fully.
The present invention has more traditional connector and is light and handy and the few advantage of manufacturingization expense.Wire armouring clamping device can be used in the cable of any diameter in the scope of a broad of being scheduled to.
The present invention is with reference to accompanying drawing further narration as an example, and this figure is the longitudinal sectional drawing according to the circuit connector of the present invention in manufacture process.
The figure shows the single part metals head (2) of circuit connector, had three pipes (3) to be fixed on the inside.Pipe (3) is to make with a kind of polyester dough moulding material of thermosetting, and is fixed in the ferrule with a kind of adhesive of epoxy.
Each pipe (3) is an insulator that is formed by the joint (4) on lead (5) end of each self-shileding of three-core line wire armoured cable (6) structure.Joint (4) is with copper one-tenth and is wound on the lead (5) of exposure, remains in the corresponding pipe (3) with a brass contact retainer ring (7) that is screwed on the joint.One insulating sleeve (8) is made of a kind of heat shrinkable plastics, does not have the interval of the twisted wire of insulating compound with maintenance around the interface of each coiling.Metal parts will embed it at interval in suitable process.
Cable armouring (9) is connected to a clip (10), and this clip is installed on the metal supporting pillar (11), and post (11) is screwed into ferrule (2) and oppositely extends.Clip (10) comprises three beckets (12), and cable conductor is worn ring and mistake, and ring is to be tightened together with the armouring that is clipped between the ring by the nut (13) that is screwed on the supporting pillar (11).
In this special example, cable (6) comprises the lead (5) of three shieldings.Conductor shielding (14) is mechanically and electrically to be connected to clip (10) by a trip bolt (15).
One brass shielding grid (16) be placed in joint and lead around to form an external shield, grid is mechanically and electrically to be connected to ferrule (2) and clip (10) by clamping ring (17,18).
The mould of one two part (19) constitute by cast iron and within it the portion surface have a polytetrafluorethylecoatings coatings, be clipped in then ferrule (2) and cable (6) around, and a kind of poly-mephenesin Carbamate casting resin is injected mould, till space (20) in being full of all shieldings and the shielding embedded resin the inside.Behind hardening of resin, anchor clamps and mould are removed, the connector of finishing is just arranged.
