Abstract
A middle connector of a pretightening insulation bus relates to a connector for middle connection of the insulation conductive tube bus. The middle connector comprises a pretightening copper sleeve with an axial opening inside and two symmetrical pretightening stainless steel sleeves outside; the outer side of the pretightening copper sleeve and the inner sides of two pretightening stainless steelsleeves adopt inclined planes which are matched with each other; and the inclination slope of the inclined planes is 1.5 to 3 degrees. When in use, ends of two segments of insulation tube buses are placed in the pretightening copper sleeve; the pretightening stainless steel sleeves are sleeved outside the insulation tube buses; the end surfaces of two symmetrical stainless steel sleeves are clamped and tightened through the clamp; two contact surfaces of the stainless steel sleeves are welded and the polishing treatment is performed; and a middle connector of a preset screen insulation cableis adopted on the outer layer, so that the integral structure is formed by the middle connector and the two segments of insulation conductive tube buses. The utility model does not adopt bolted connection, the appearance of the connector part is smooth, the contact is compact, the connection is reliable, the electrical contact is good, and the electric conductivity is strong; the utility model canadapt to cold-hot contraction in the operation process, has simple installation and operation, and adapts to the field installation requirements.
Description
Technical field
The utility model relates to a kind of middle joint that connects of contact tube bus that is used to insulate.
Background technology
When insulation contact tube bus is installed at the scene at present, connect the bolted mode that adopts two-sided anchor ear in the middle of the pipe bus both at home and abroad, its outer shape is bigger and irregular, has limited the installation and the scope of application of isolated bus; Its fastening employing be that standard component connects, the pipe bus is in operation and shakes greatlyyer electrodynamic effect under, bolt can cause becoming flexible, and has increased failure rate and repair and maintenance difficulty virtually; And there is electrical safety hidden danger.
Existing " transition joint between a kind of cable core " (China Patent No. 90211396), it is that a joint has through hole or two ends respectively are the short tube of circular blind hole, a fittings body is arranged, the two ends of fittings body, the front all respectively is a bullet, and the back respectively is a cylinder all, and a special nut is respectively arranged on the two ends of fittings body, along with being screwed into respectively of two ends special nut, just the cable core that penetrates the fittings body two ends can be locked the back connection respectively.
Summary of the invention
The purpose of this utility model aims to provide that reliable, the electric contact of a kind of connection is good, electric conductivity is strong, operation is difficult for loosening, smooth-shaped, the transition joint of the simple prefastening isolated bus of fitting operation.
The implementation of the utility model purpose is, the transition joint of prefastening isolated bus, prefastening copper sheathing and its outer prefastening stainless steel sleeve by inside are formed, the prefastening copper sheathing has axially open, the prefastening stainless steel sleeve is two of symmetry, the inner surface of prefastening copper sheathing outer surface and two prefastening stainless steel sleeves is the inclined-plane that matches, and the gradient on inclined-plane is 1.5 °-3 °.
When using the utility model, the termination of two sections insulation contact tube buses that need are connected places and has in the axially open prefastening copper sheathing, two prefastening stainless steel sleeves of overcoat are clamped the end face of prefastening stainless steel sleeve with anchor clamps, and are tightened up, driving inner prefastening copper sheathing tightens up, after making two sections insulation contact tube buses connect closely, two contact-making surfaces with the prefastening stainless steel sleeve weld together again, form weld seam, to guarantee the grip force of this device, can not become flexible.After the welding, polishing again, skin adopts presetting system insulated shield cable intermediate connector again, makes the utility model and two sections insulation contact tube buses form overall structure.
The utility model does not adopt syndetons such as bolt, blank area smooth in appearance; Contact closely, operation is difficult becomes flexible, and connects reliable; Electric contact is good, electric conductivity is strong; Can adapt to the cold and hot contraction of running; Fitting operation is simple, adapts to on-the-spot installation requirement.
Description of drawings
Fig. 1 is the utility model structural representation,
Fig. 2 is the utility model general assembly view.
Embodiment
With reference to Fig. 1, the utility model is made up of prefastening copper sheathing 1 and its outer prefastening stainless steel sleeve 2 of inside, prefastening copper sheathing 1 has axially open, prefastening stainless steel sleeve 2 is two of symmetry, the inner surface of prefastening copper sheathing 1 outer surface and two prefastening stainless steel sleeves 2 is the inclined-plane that matches, and the gradient on inclined-plane is 1.5 °-3 °.
With reference to Fig. 2, when using the utility model, the termination of two sections insulation contact tube buses that need are connected places and has in the axially open prefastening copper sheathing 1 two prefastening stainless steel sleeves 2 of overcoat, with anchor clamps the end face of prefastening stainless steel sleeve is clamped, and tighten up, drive inner prefastening copper sheathing 1 and tighten up, make two sections insulation contact tube buses 3 connect closely after, two contact-making surfaces with the prefastening stainless steel sleeve weld together again, form weld seam 4,, can not become flexible to guarantee the grip force of this device.After the welding, polishing again, skin adopts presetting system insulated shield cable intermediate connector 5 again, makes the utility model and two sections insulation contact tube buses 3 form overall structure.
Two contact-making surfaces of two prefastening stainless steel sleeves are stepped, so the weld seam 4 that forms also is stepped.
Be added with shielding insulation structure sheaf 6 outside two sections insulation contact tube buses beyond the utility model, shielding insulation structure sheaf 6 is in presetting system insulated shield cable intermediate connector 5.
Claims (2)
1, prefastening isolated bus transition joint, it is characterized in that forming by prefastening copper sheathing and its outer prefastening stainless steel sleeve of inside, the prefastening copper sheathing has axially open, the prefastening stainless steel sleeve is two of symmetry, the inner face of prefastening copper sheathing outside and two prefastening stainless steel sleeves is the inclined-plane that matches, and the gradient on inclined-plane is 1.5 °-3 °.
2, prefastening isolated bus according to claim 1 transition joint, the welding contact-making surface that it is characterized in that two prefastening stainless steel sleeves is stepped, so the weld seam (4) that forms also is stepped.
