Abstract
Disclosed is a connecting device for a bus duct. The connecting device comprises a metal case, a conductive connecting block for connecting the socket-outlet of the bus duct, and an insulating block, wherein the conductive connecting block and the insulating block are disposed inside the metal case; the metal case, the conductive connecting block, and the insulating block are connected through a bolt penetrating the metal case; the bolt is sleeved with an insulating tube; the insulating tube is sleeved with an insulating washer; a mounting hole is formed in the insulating block; the diameter of the mounting hole is matched with the outer diameter of the insulating washer; the thickness of the insulating washer is matched with that of insulating block; the connecting device of the bus duct, with reasonable improvement on the structure, particularly with the reinforcement design of the insulating washer, further ensures the reliability of connecting structure, prevents the short circuit resulting from the permeation of the water vapor from the bolt, and plays a role of protecting the insulating block.
Description
Technical field
The utility model relates to bus duct field, particularly a kind of jockey for bus duct.
Background technology
At present, existing a kind of bus-bar slot connecting apparatus, it is mainly made up of metal side plate, collets and bolt; After the same phase conductor joint of different bus ducts stacks mutually, separated by collets, then by metal side plate and coordinating of bolt, conductor tab is fixed.The likely just part contact of conductor tab of what described conductor tab stacked mutually have through hole, connect defective tightness, between same phase conductor joint, produce loose contact, electric discharge and burn out the phenomenon of joint.The words of separating by insulated tube exist again insulated tube place easily to damage the problem that causes short circuit, and the easily infiltration again of insulated tube place, still have certain danger.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of jockey for bus duct.
The utility model solves the technical scheme that its technical problem adopts:
A kind of jockey for bus duct, the conduction contiguous block and the collets that comprise metal shell, arrange for the connection bus line of rabbet joint, wherein said conduction contiguous block and collets are positioned at metal shell, described metal shell, conduction contiguous block are connected by the bolt that runs through metal shell with collets, on described bolt, be set with insulated tube, described insulated tube is set with insulating washer outward, on wherein said collets, have installing hole, the radius of described installing hole matches with the outer radius of insulating washer, and the thickness of described insulating washer matches with the thickness of collets.
Get loose because of vibrations for fear of bolt, the part that described bolt is positioned at outside metal shell is provided with yielding rubber circle.
The beneficial effects of the utility model are: the jockey of described bus duct is by rational structural improvement; the particularly Design of Reinforcement of insulating washer; further ensure the reliability of syndeton, avoided steam to infiltrate and cause short circuit from bolt, and can play the effect of protection collets.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the actual schematic diagram that uses of the present utility model.
Embodiment
With reference to Fig. 1, Fig. 2, a kind of jockey for bus duct, comprise metal shell 1, arrange 2 conduction contiguous block 3 and collets 4 for the connection bus line of rabbet joint, wherein said conduction contiguous block 3 and collets 4 are positioned at metal shell 1, and metal shell 1 can arrange fin 11 as required.The two ends of conduction contiguous block 3 contact with the bus line of rabbet joint row 2 of both sides respectively, and collets 4 are for separating the bus line of rabbet joint row 2 of levels.Described metal shell 1, conduction contiguous block 3 are connected by the bolt 5 that runs through metal shell 1 with collets 4, thereby are compressed and connected bus line of rabbet joint row 2 by 5 conduction contiguous blocks 3 of bolt and collets 4.On described bolt 5, be set with insulated tube 6, avoid bolt 5 directly to contact and cause short circuit with bus line of rabbet joint row 2.Described insulated tube 6 is outer is set with insulating washer 7, on wherein said collets 4, has installing hole, and the radius of described installing hole matches with the outer radius of insulating washer 7, and the thickness of described insulating washer 7 matches with the thickness of collets 4.Because collets 4 have the effect that compresses conduction contiguous block 3; can produce certain deformation; therefore insulating washer 7 requires with more wear-resisting insulating material manufacture, avoid steam to cause short circuit from bolt 5 and 6 infiltrations of edge pipe, and the bolt installation position place of protection collets 4 reduces wear
The part that described bolt 5 is positioned at outside metal shell 1 is provided with yielding rubber circle 8, reduces that bolt 5 vibrations cause getting loose or wearing and tearing to collets 4.
According to above-mentioned principle, the utility model can also carry out suitable change and amendment to above-mentioned execution mode.Therefore, the utility model is not limited to embodiment disclosed and described above, also should fall in the protection range of claim of the present utility model modifications and changes more of the present utility model.
Claims (2)
1. the jockey for bus duct, comprise metal shell (1), for connection bus line of rabbet joint row's (2) conduction contiguous block (3) and collets (4), wherein said conduction contiguous block (3) and collets (4) are positioned at metal shell (1), it is characterized in that: described metal shell (1), conduction contiguous block (3) is connected by the bolt (5) that runs through metal shell (1) with collets (4), on described bolt (5), be set with insulated tube (6), the outer insulating washer (7) that is set with of described insulated tube (6), wherein said collets have installing hole on (4), the radius of described installing hole matches with the outer radius of insulating washer (7), the thickness of described insulating washer (7) matches with the thickness of collets (4).
2. a kind of jockey for bus duct according to claim 1, is characterized in that: described bolt (5) is positioned at the outer part of metal shell (1) and is provided with yielding rubber circle (8).
