Description
Technical field
This utility model relates to the conductive connecting device of the electric elements such as locomotive converter plant, high and low voltage switch, chopper, fuse, controller, is specially a kind of compact conducting copper attachment structure.
Background technology
Copper bar, also referred to as busbar or current-carrying are arranged, and are to hold current-carrying a kind of conductor, because of it, to have resistivity low, and bending is good, the feature that electric conductivity is superior, it is widely used in high-low pressure electrically, in switch contact, complete power distribution equipment, play connection electrical equipment and carry the effect of electric current.The connected mode of copper bar, first calculates according to current-carrying capacity size and selects the specification being suitable for, and in its secondary foundation cabinet, each purposes connecting electricity piece determines copper bar integral layout, trend, to meet switching performance and requirement.While taking into full account that cabinet bulk limits, with easy for installation, maintenance safety, connection is reliable, it is succinct as objective to save time.Therefore, correct selection conducting copper connected mode seems extremely crucial to the reliability being conductively connected, and connects the improper possibility arising that scorification copper bar, thus causes electrical equipment malfunction.
Connected mode between copper bar and copper bar, electric components, typically has screwed hole to connect (being only limitted to copper bar below thickness 6mm, maximum diameter of hole M4), unthreaded hole connection, riveting nut connection.No matter using which kind of connected mode, the contact of joint face must be closely reliable, has enough and lasting contact pressure to meet, even scaling loss of not generating heat because of life-time service and vibration between conducting copper.The length of bolt is advisable with 5 ~ 8mm outside screw thread can expose nut after completing fastening simultaneously, has both ensured to use requirement, has saved space, integral layout also neat appearance.But in converter plant, switching control device, often due to cabinet is limited by locus or other factors, the bulk of cabinet is limited, each connection cellular construction is compact, connects complexity.When the connection of copper bar needs to be in cabinet the inside or narrow space because of structure, various fastening means all cannot use, suitable frock is not had to use yet, the connection of copper bar can only manually grope and operate the practical experience of employee and complete, and wasting time and energy, it is safe and reliable also cannot to ensure that copper bar connects.
Before, the applicant has applied for the utility model patent of " easily connecting high-strength conductive copper bar " (patent No.: ZL201420349739.9).Flange face locking nut is fixed on copper bar by it by bracket sunk head rivet, determines nut installation site, only need to tight a bolt during installation, just can complete the connection of copper bar and various electrical equipments.This kind of connection need not special fastening instrument and frock, it is achieved that can conveniently operate in the place of narrow space, prevents connecting bolt from loosening with fixing lock for bracket jack panel simultaneously.If but connect vigour part and be in the specific position (heavier-weight) of cabinet, and less with side cabinet distance, on top, bottom, side cabinet, said structure just cannot meet its connection request.
Consider, be highly desirable to that a kind of structure is compacter at present, be easier to the copper bar connecting structure of local operation at narrow space.
Summary of the invention
This utility model is to solve current copper bar connecting structure not adapt to the technical problem that small space connects, it is provided that a kind of compact conducting copper attachment structure.
This utility model adopts the following technical scheme that realization: a kind of compact conducting copper attachment structure, including one have at least one screw and at least one connecting hole on it be conductively connected copper bar, each screw is provided with a bolt；Described bolt is arranged through screw to front by being conductively connected the copper bar back side；It is conductively connected the copper bar back side on the head of each bolt, is all installed with a bracket；The head of described bolt is tightly stuck in bracket.
Further, be conductively connected described in copper bar rectangular and its on have a pair screw and a pair connecting hole, the pair of screw and a pair connecting hole and be respectively positioned on the long centrage being conductively connected copper bar；The pair of screw is symmetrical set and near the center being conductively connected copper bar with the short central line being conductively connected copper bar for axle；The pair of connecting hole is symmetrical set and respectively close to two minor faces being conductively connected copper bar with the short central line being conductively connected copper bar for axle；Described bolt is arranged through screw to front and the head of bolt and be conductively connected copper bar and be also lined with packing ring by being conductively connected the copper bar back side；In inverted U structure in the middle part of described bracket, the two ends of inverted U structure has all extended obliquely downward a linkage section；Each linkage section connects one horizontal-extending section；Rivet hole is all had on the pair of horizontal-extending section；Described bracket is conductively connected on copper bar by being fixed on through the rivet of rivet hole；The line of two rivet holes of described bracket is parallel with the short central line being conductively connected copper bar；The head of described bolt is tightly stuck in the inverted U structure of bracket.
Further, described bolt uses hex bolts；Described rivet uses sunk head rivet.
The purpose of this utility model is to overcome deficiency of the prior art, a kind of new copper bar connected mode is provided, while meeting existing patented technology advantage, the space of connecting portion and adjacent copper bar spacing can be made, on the premise of meeting minimum safe distance, further reduce, more compact can more reasonably save space.Provide more choices mode to user simultaneously.
The technical scheme of conducting copper attachment structure described in the utility model: select hex bolts, packing ring and bracket sunk head rivet to be fixed on copper bar and realize, the inverted U structure of bracket can prevent connecting bolt from rotating and loosen, depending on the size of inverted U physical dimension and the highly desirable specification according to selection bolt, the design of its height is i.e. wanted effectively to control bolt and is rotated, can rationally dodge again bolt and packing ring location conflicts (see Fig. 1,2), thus ensure that attachment security is reliable.This connected mode, again without specific purpose tool and frock during installation, is suitable for the position required at narrow space or copper bar closure, the especially connection of unilateral direction.Structure is simpler, installs more convenient, more saves space.
Fig. 3,4 it is this conducting copper attachment structure figure: Fig. 3,4 structures using this connected mode exactly, according to conducting copper connection member requirement on converter plant, switching control device, the packing ring that hex bolts puts same specification penetrates the screw of copper bar, then the corresponding flat of hexagonal bolt head is stuck in the U-shape structure of bracket, again that the rivet hole on bracket is corresponding with rivet hole on conducting copper, it is fixed with sunk head rivet, bolt is tightly fastened with being connected copper bar, for it with each catalyst, the fixing connection that is connected between unit advantage is provided.
This utility model simple in construction, easy for installation, meet product structure design requirement.
