Description
Technical field
The utility model relates to low pressure draw out switchgear technical field, particularly a kind of electric power source distribution device that is used for the low pressure draw-out type functional units of low pressure draw out switchgear.
Background technology
The syndeton that the employing copper bar that existing market is used is done plug in the electric power source distribution device of power distribution and copper bar as shown in Figure 1, the end of copper bar is inserted plug to front curve and is realized being connected of copper bar and plug, such design limit reducing of electric power source distribution device volume, the degree of depth that electric power source distribution device takies cabinet is too big.It is higher to adopt lead to do the cost of electric power source distribution device of power distribution, and performance is also not fully up to expectations, and Power Level does not increase, and generally is only limited in 63A.Simultaneously because the main power plugs unreasonable structure, installation accuracy to the cabinet drawer is all very high, when the installation accuracy of cabinet and drawer does not reach the accuracy tolerance of main power plugs, the connection meeting of plug is very unreliable, cause functional unit and electric power source distribution device temperature rise, the tie point of plug is easy to generate burnout phenomenon.
The utility model content
In order to overcome above-mentioned deficiency, the utility model provides a kind of electric power source distribution device that can reduce to take the low pressure draw-out type functional units of cabinet depth, it makes in the cabinet can the bigger drawer of fitting depth, and the drawer that this degree of depth is bigger is convenient to manufactory enough space mounting electric elements.
The technical solution adopted in the utility model is: a kind of electric power source distribution device of low pressure draw-out type functional units, comprise plug and the copper bar that is used for power distribution that is connected with plug in the electric power source distribution device, be provided for the projection of attachment plug and copper bar on the upper surface of copper bar and/or lower surface, the plug horizontally set inserts projection on the copper bar and realizes and being connected of copper bar.The original end with copper bar of this design change bends the design as the link of copper bar and plug forward, and the thickness that reduces electric power source distribution device is achieved.
Projection and copper bar are welded to connect.
Plug is made of plug fixed mount, paired plug blades, spring leaf, steady pin, and the middle part that steady pin passes paired plug blades is swung plug on fixed mount, and spring leaf is arranged between plug blades and the plug fixed mount and compresses plug blades.Relative and the original plug construction of this plug construction can guarantee bigger tolerance, lower temperature rise, and tolerance can not have problems because contact is unreliable when off normal connects about 2mm yet.
The beneficial effects of the utility model are: simple in structure, the degree of depth that takies cabinet is little, the syndeton of the use of copper bar and copper bar and plug makes the current class of electric power source distribution device can reach 125A, drawer can obtain bigger deep space, the more lengthening that drawer can be done, in the drawer that has increased volume, can make manufactory that enough space mounting electric elements are arranged, guarantee the reliability of electrical equipment in it.
