Abstract
The utility model discloses a connecting structure for a low voltage tubular bus bar and a link fitting, which is characterized in that the connecting structure consists of an inner supporting pipe, a tubular bus bar body and the link fitting that are fixedly sheathed and connected from inside to outside. The connecting structure is convenient for field installation, 360-degree circumferential surface omnibearing contact can be formed between the link fitting and the tubular bus bar, thus fully guaranteeing effective contact area, the phenomenon that the temperature of a connecting part rises dose not occur, and the ventilation inside the tubular bus bar is guaranteed, thus having good radiating performance.
Description
Technical field
The utility model relates to a kind of syndeton, is specially to be used for being connected of industry and the 100-1000V voltage in civil engineering field, 0-1250A current class metallic conduction tubular bus.
Background technology
The connected mode of existing low pressure tubular bus has two kinds at present: a kind of is to adopt the fastening mode of metal anchor ear screw to connect, this connected mode shortcoming is because its stress surface is on a line, easily because of unbalance stress makes that touching face reduces, owing to not guaranteeing that effective contact-making surface causes the too high phenomenon of connector temperature in service; On the other hand because the fastening place of screw forms the step of a projection, for the recovery of follow-up insulating barrier brings very big difficulty.Another kind is the mode that adopts the on-the-spot welding of metal hood type, and this connected mode had both needed to hold tightly with the instrument crimping at the scene, needs naked light welding at the scene again, and difficulty of construction is big, has also increased unsafe factor.
The utility model content
The purpose of this utility model is, overcomes the deficiencies in the prior art, and a kind of novel syndeton is provided.
The technical solution adopted in the utility model is as follows:
The low pressure tubular bus connects the syndeton of gold utensil, and syndeton is by inner support pipe, tubular bus body and be connected that the gold utensil from-inner-to-outer is fixedly sleeved to be formed.
As improvement, described inner support pipe is a hollow tubular structures.
As improvement, described inner support tube end is provided with restriction protrusion.
As improvement, described inner support tube outer surface is provided with equally distributed groove.
The beneficial effects of the utility model are, and are on-the-spot easy for installation, connect can form 360 degree between gold utensil and the tube type bus periphery is comprehensive to contact, and fully guaranteed effective contact area, can not produce the phenomenon that the connector temperature raises; Owing to adopt the crimping mode to form a circular surface, for good condition has been created in the recovery of follow-up insulating barrier; The inner support pipe adopts the non-magnetic rustproof steel, forms firm annular support surface, makes connection gold utensil and tubular bus not produce distortion when crimping, has guaranteed simultaneously to connect gold utensil and manage fixedlying positioning and enough contact-making surfaces of bus bulk; Because stay pipe is hollow, has also guaranteed the inner air circulation of pipe bus, thereby had good performance of heat dissipation.
Description of drawings
Fig. 1 is the syndeton schematic diagram of the utility model embodiment.
Fig. 2 is the syndeton profile of the utility model embodiment.
Embodiment
The low pressure tubular bus connects the syndeton of gold utensil, referring to Fig. 1, Fig. 2, is packaged the back from inside to outside and is formed with special-purpose Press Plier crimping by inner support pipe 1, low pressure tubular bus 2, connection gold utensil 3, and the three is hollow tubular structures.Bus inner support pipe adopts the non-magnetic rustproof steel, form firm annular support surface, make connection gold utensil and tubular bus when crimping, not produce distortion, thereby guaranteed to connect gold utensil and enough contact-making surfaces and firm location have been arranged with the pipe bus bulk, in addition because stay pipe is hollow, also guarantee the inner air circulation of pipe bus, thereby guaranteed its good performance of heat dissipation.
The inner support tube end is provided with restriction protrusion 4, and outer surface has equally distributed groove, and the support strength in the time of both can guaranteeing crimping can position the connecting portion of tube type bus again, has guaranteed also that simultaneously supporting body can not generate heat under effect of electric field.
Described embodiment is the utility model preferred implementation; be not limited by the examples but only do not represent; other any do not deviate from any change, the modification done under the situation of spirit of the present utility model and principle, substitutes, combination, simplify; all should be considered as the substitute mode with the utility model equivalence, all be included within the protection range of the present utility model.
Claims (4)
1. the low pressure tubular bus connects the syndeton of gold utensil, it is characterized in that: syndeton is by inner support pipe, tubular bus body and be connected that the gold utensil from-inner-to-outer is fixedly sleeved to be formed.
2. syndeton as claimed in claim 1, described inner support pipe is a hollow tubular structures.
