Abstract
The utility model discloses a kind of adjustable contact bus connecting device, comprise bus connector and be located at the bus terminal at bus connector two ends, bus terminal is provided with connecting hole; Bus terminal is flat, and bus terminal comprises close end and distal portion, is provided with recessed groove on close end, and the thickness of close end is less than the thickness of distal portion, and the width of close end is greater than the width of distal portion.This structure can increase area in electrical contact between bus terminal, makes the overcurrent capability of bus terminal each several part suitable, and therefore, conductivity switching performance is good, and contact resistance is little, and temperature rise is low; And the height error of bus both sides switchgear is adjusted by the distortion of recessed groove, thus make connection more reliable, improve the stability that contact is installed.
Description
Technical field
The utility model relates to a kind of adjustable contact bus connecting device.
Background technology
Bus connecting device is mainly by insulating joint, bus casing and bus connecting piece, and wherein bus casing is connected on insulating joint, and the end of bus connecting piece is plugged on sleeve pipe and realizes and being electrically connected.Bus connecting piece is mainly made up of bus connector and bus terminal, as at application publication number being is the method for connecting bus that discloses a kind of solid insulation ring main unit in the 2012.12.14 patent documentation that openly day is 2013.4.24 the CN10306500A applying date, also disclose a kind of bus connecting device, this bus connecting device comprises bus casing, double end long bolt, grounding wire component, long threeway, adjusting washer (disk), plain cushion, bullet pad, copper connecting tube, insulating plug, sealing cap, flexible bus, long four-way, ground loop, stress tube, bus terminal simultaneously.Although the method has solved the problem that bus is difficult to dismounting,, the contact-making surface of adjacent bus terminal is little, fixing crimped status is unstable, makes the conduction switching performance of bus terminal unstable, simultaneously, contact resistance increases, and easily produces heat, thereby can shorten the useful life of bus connecting device.
Summary of the invention
In order to increase conductivity contact area between bus terminal, improve the stability that contact is installed, improve the conduction switching performance between bus terminal, reduce contact resistance, reduce the generation of heat, the utility model provides a kind of adjustable contact bus connecting device.
For achieving the above object, a kind of adjustable contact bus connecting device, comprises bus connector and is located at the bus terminal at bus connector two ends, bus terminal is provided with connecting hole; Bus terminal is flat, and bus terminal comprises close end and distal portion, is provided with recessed groove on close end, and the thickness of close end is less than the thickness of distal portion, and the width of close end is greater than the width of distal portion.
Said structure, because bus terminal is flat, and comprise close end and distal portion, the thickness of close end is less than the thickness of distal portion, the width of close end is greater than the width of distal portion, like this, in the time of two adjacent bus terminal docking, recessed groove has formed the portion of dodging and has made can realize large-area contact between distal portion, simultaneously, the sectional area of close end and distal portion is suitable, make the overcurrent capability of bus terminal each several part suitable, therefore, conductivity switching performance is good, contact resistance is little, and temperature rise is low; And the height error of bus both sides switchgear is adjusted by the distortion of recessed groove, thus make connection more reliable, improve the stability that contact is installed.
Further, bus connector and close end are arc transition, so that one-body molded bus connector and bus terminal.
Further, bus connector is hollow copper pipe, like this, not affecting under the prerequisite of electric conductivity, can save material, reduces weight.
Further, the both sides of close end are circular-arc, and the end of distal portion is circular-arc, so that bus terminal is plugged in jointing.
Brief description of the drawings
Fig. 1 is the schematic diagram of adjustable contact bus connecting device.
Fig. 2 is the exploded view of adjustable contact bus connecting device.
Fig. 3 is the schematic diagram of bus connector and bus terminal.
Fig. 4 is the schematic diagram of bus terminal.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.
As depicted in figs. 1 and 2, adjustable contact bus connecting device comprises insulating joint 1, bus casing 2, connecting bolt 3, plain cushion 4, bullet pad 5, nut 6, insulating plug 7, sealing cap 8, bus connector 9, bus terminal 10, grounding assembly 11.
Insulating joint 1 can be selected tee T insulating joint and cross insulating joint according to connection requirement.One end of bus casing 2 is plugged in a through hole of corresponding insulating joint 1.In bus terminal 10 extend into insulating joint 1 and when connecting hole 1021 is coaxial with through hole, one end of connecting bolt 3 is threaded connection in the screwed hole of bus casing 2 through connecting hole 1021.Plain cushion 4 is enclosed within on the connecting bolt 3 that is positioned at bus terminal top, and bullet pad 6 is enclosed within on the connecting bolt 3 that is positioned at plain cushion 4 tops, and nut 6 is threaded connection on the other end of connecting bolt 3, and utilizes nut 6 to lock bus terminal 10.Insulating plug 7 is arranged in another through hole of insulating joint 1, and sealing cap 8 is enclosed within on insulating joint 1, and covers insulating plug 7.
As shown in Figure 3 and Figure 4, bus connector 9 is hollow copper pipe, like this, not affecting under the prerequisite of electrical conduction, can save material, reduces weight, reduces costs.Bus terminal 10 is flat, bus terminal 10 comprises close end 101 and distal portion 102, on close end 101, be provided with recessed groove 1011, bus connector 9 is arc transition with close end 101, the both sides of close end 101 are circular-arc, the end of distal portion 102 is circular-arc, the thickness of close end 101 is less than the thickness of distal portion 102, the width of close end 101 is greater than the width of distal portion 102, like this, in the time of two adjacent bus terminal docking, recessed groove 1011 has formed the portion of dodging and has made can realize large-area contact between distal portion, simultaneously, the sectional area of close end 101 and distal portion 102 is suitable, make the overcurrent capability of bus terminal each several part suitable, therefore, conductivity switching performance is good, contact resistance is little, temperature rise is low, and because being provided with recessed groove, the height error of bus both sides switchgear is adjusted by the distortion of recessed groove, improve the stability of contact has been installed, thereby made to connect more reliable.
