One end of the device box body is an opening end which is in butt joint with an adjacent box body, and the other end is a bus lead-in end. A set of vertical access conductive bars are led in by the bus lead-in end in a spaced manner. The access conductive bars bend at vertical right angle in a spaced manner after coming into the box body. The bending parts are electrically connected with vertical surfaces of L-shaped connecting conductive bars which bend at horizontal right angle.

Description

A kind of anti-settling bus connecting device

Technical field

The utility model relates to a kind of bus connecting device, and especially a kind of anti-settling bus connecting device, belongs to technical field of electric power transmission facility.

Background technology

For a long time, connection between adjacent bus be by between the adjacent bus duct of being rigidly connected of securing member for being rigidly connected, although this connected mode can guarantee to be electrically connected to reliably between adjacent bus, but when foundation construction produces larger displacement deformation because of reasons such as sedimentations, easily damage, occur connecting fault.

For addressing this problem, the Chinese patent application that application number is 200910139924.9 discloses a kind of transformable bus slot connector, and its innovation essence is may occur sedimentation displacement distortion by having the removable conductive plate adaptation of regulating tank.The shortcoming of its existence is not only complex structure, and the connection between conductive plate can not be too tight, otherwise its adaptability to displacement deformation can be affected, but connect, tightly contact resistance can be do not increased again, the reliability that impact is electrically connected to, the connection degree of tightness while therefore installing is difficult to hold.

In addition; application number is that 200920235191.4 Chinese patent discloses a kind of Special flexibility bridge connector of wind power bus duct; it utilizes the squeezable characteristic of bellows and the conductor that is flexible coupling suitably to solve the site error between two joint bus ducts while installing; but soft connecting link itself has unsteadiness; electric conductor is wherein difficult to practical protection, so reliability, fail safe is not good enough.

Retrieval discovery, the Chinese patent that application number is 201020104527.6 discloses a kind of waterproof settling box for bus ducts, but it discloses the waterproof construction of docking casing, does not relate to the anti-settling measure of electrical connection.

Utility model content

The purpose of this utility model is: the shortcoming existing for above-mentioned prior art, proposes a kind of anti-settling bus connecting device that can not only can adapt to sedimentation deformation distortion under the reliable electrical connection of assurance prerequisite, can bear certain level face displacement deformation simultaneously.

In order to reach above object, anti-settling bus connecting device of the present utility model comprises casing, and one end of described casing is and the openend docking in abutting connection with casing that the other end is bus leading-in end; Described bus leading-in end is introduced the access busbar of one group of vertically-arranged in mode spaced apart from each other, described access busbar bends with the vertical right angle of mode spaced apart from each other after entering casing, L shaped vertical the electrical connection that is connected busbar that bending place bends with horizontal right angle; The horizontal plane of described connection busbar is electrically connected to the corresponding connection busbar in docking casing by ductile metal sheet.

Owing to being electrically connected to by ductile metal sheet between connection busbar corresponding in a pair of casing of the utility model docking, therefore there is outer just interior soft feature, even two tanks gene basis sedimentation and larger displacement deformation occurs, also can automatically adapt to and keep reliable electrical connection, and the vertical right angle bending of vertically-arranged access busbar and the horizontal right angle bending of L shaped connection busbar have formed space exchanging structure, can the displacement of horizontal plane be converted to vertical deviation to a certain extent by reversing, and then automatically adjust by ductile metal sheet.

Adopt after the utility model, not only mainly can adapt to sedimentation deformation distortion, simultaneously can be at the displacement deformation that to a certain degree absorbs horizontal plane, thereby when automatically adapting to foundation settlement, can also avoid the expanding with heat and contract with cold of horizontal direction, vibration deformation, its outer just in soft structure guaranteed reliable, the safety of supply line.

The utility model further improves, and the port that the other end of described casing connects by rectangular flange circle forms bus leading-in end, the outer middle side part of the described port intake that extends outwardly out.

The utility model is further perfect is, described intake end is fixed upper and lower involutory insulation isolation and covered, and the grid that lid forms and the access busbar of vertically-arranged matches is isolated in the insulation after involutory fixing.

The utility model further improves, and vertical horizontal quarter bend of described connection busbar folds after lower plane, and the transition inclined-plane having a down dip by court bends out horizontal plane again.

The utility model further improves again, after one end overlap joint of the toughness copper sheet that described horizontal plane swells upward with middle part, is electrically connected to.

Embodiment

Embodiment mono-

The basic structure of the present embodiment anti-settling bus connecting device as shown in Figure 1, comprises the casing 4 of cuboid, and one end of this casing is and the openend docking in abutting connection with casing that the port 6 that the other end connects by rectangular flange circle 5 forms bus leading-in end.The outer middle side part of port 6 intake that extends outwardly out, the fixing upper and lower involutory insulation isolation of intake end covers 7, involutory insulation isolation after fixing cover 7 and is formed the grid that the access busbar 1 with vertically-arranged matches, thereby make one group five vertically-arrangeds that are parallel to each other access busbars 1, in mode spaced apart from each other, introduces bus leading-in end (referring to Fig. 2).

Access busbar 1 enters after casing, as shown in Figure 3, the vertical right angle bending towards both sides respectively in mode spaced apart from each other, each bending place, right angle is shaped with four perforation, and by securing member or periphery welding and perforation place slugging, is realized reliably and being electrically connected to afterwards with vertical overlap joint of the L shaped connection busbar 2 of corresponding horizontal right angle bending.Vertical the horizontal quarter bend that connects busbar 2 folds after lower plane, the transition inclined-plane having a down dip by court bends out horizontal plane again, on this horizontal plane, be also shaped with four perforation, the toughness copper sheet 3(swelling upward with middle part is referring to Fig. 1) one end overlap joint after by securing member or periphery welding and the slugging of boring a hole out, be reliably electrically connected to, and realize thus and corresponding connection busbar electrical connection in docking casing.

The anti-settling bus connecting device of the present embodiment has outer just interior soft feature, its inner electric conductor obtains practical security protection, its access busbar not only self can bear certain deformation with the right angle bending that is connected two different directions of busbar, and the vibration of sedimentation deformation and horizontal plane and thermal expansion Displacement transfer can be arrived to toughness copper sheet.And connect the distortion that fluctuating bridge shape syndeton that having a down dip of busbar form with toughness cylinder sheet protuberance can more efficiently absorption displacement causes, guarantee to be electrically connected to reliably.

In addition to the implementation, the utility model can also have other execution modes.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection range of the utility model requirement.
