Abstract
The utility model discloses a junction structure of vertical copper bars and a plugin in a high-low voltage power distribution cabinet. The junction structure comprises the vertical copper bars and the plugin which is clamped with the vertical copper bars. Each vertical copper bar is two copper pipes which are parallelly arranged at interval. A main bus-bar lap plate is fastened on the upper ends of two copper pipes which form one vertical copper bar through threaded fasteners. The plugin is provided with hollow contacts. Leaf springs are disposed in the hollow contacts. The leaf springs make outer walls of the hollow contacts have elasticity. The contact can be inserted and clamped between two copper pipes which form one vertical copper bar, and under the action of the leaf spring, the contact tightly fits with outer surfaces on inner sides of the two copper pipes and the contact and the copper pipes keep good contact. The junction structure is advantaged in that heat radiation efficiency of the vertical copper bars is high, processing and installation are more convenient, space taken by the vertical copper bars and the main bus-bar lap plate is small, and connection of the vertical copper bars and the plugin is reliable.

In high-low voltage electric power distribution cabinet, be conventionally provided with several drawers with different control functions, the control function of each drawer is realized by the control circuit being arranged in each drawer, the plug-in unit that main control circuit in the rear end of each drawer is installed with several and drawer is conducted, also be provided with the vertical copper bar that many groups are connected with main bus bar at the back of high-low voltage electric power distribution cabinet, as Fig. 1, shown in Fig. 2, the shape of cross section of every vertical copper bar 1 is flattened rectangular shape, its upper end is by bending, after punching, be connected with main bus bar lapping plate 2, thereby vertical copper bar 1 is connected with main bus bar, the jig arm and vertical copper bar 1 phase clamping passed through in slot with the plug-in unit 3 of slot, thereby the control circuit and the main bus bar that are positioned at drawer are conducted.
In above-mentioned high-low voltage electric power distribution cabinet there is following shortcoming with the syndeton of plug-in unit in vertical copper bar: plug-in unit 3 is by jig arm and vertical copper bar 1 clamping in slot, vertical copper bar 1 is clamped in slot, under switch short-circuit conditions, because electrodynamic effect can produce outside repulsion, cause jig arm and vertical copper bar 1 loose contact in plug-in unit 3, even can make both Joint failures; In addition, vertical copper bar 1 need to could be connected with main bus bar lapping plate 2 through bending after punching operation, and technique is more loaded down with trivial details, and main bus bar lapping plate 2 takes up room larger with the faying surface of vertical copper bar 1.
Utility model content
The technical problem of the required solution of the utility model is: provide that a kind of syndeton is simple and reliable, the syndeton of vertical copper bar and plug-in unit in the little high-low voltage electric power distribution cabinet that takes up room.
For addressing the above problem, the technical solution adopted in the utility model is: the syndeton of vertical copper bar and plug-in unit in described high-low voltage electric power distribution cabinet, comprise vertical copper bar with the plug-in unit of vertical copper bar phase clamping, each vertical copper bar is two arranged side by side and spaced copper pipes, and main bus bar lapping plate is fastened on the upper end of two copper pipes that form a vertical copper bar by threaded fastener; On described plug-in unit, be provided with the contact of hollow, the spring leaf being provided with in the contact of hollow, spring leaf makes the outer wall of the contact of hollow have elasticity, contact can insert and be stuck between two copper pipes that form a vertical copper bar, and under the effect of spring leaf, makes contact fit and keep good contacting with the intimate of two copper pipe inner sides.
Further, the syndeton of vertical copper bar and plug-in unit in aforesaid high-low voltage electric power distribution cabinet, wherein, described contact is turriform shape, so that contact inserts between two copper pipes that form a vertical copper bar.
Further, the syndeton of vertical copper bar and plug-in unit in aforesaid high-low voltage electric power distribution cabinet, wherein, threaded fastener is located in two gaps between copper pipe, main bus bar lapping plate is fastened on to the upper end of two copper pipes.
The beneficial effects of the utility model are: copper pipe is made into vertical copper bar, cavity self-assembling formation in copper pipe heat radiation venting channels, greatly improve radiating efficiency, the ampacity of the vertical copper bar that employing copper pipe is made is large, thereby the use amount that can save copper material in the situation that of same power output, has reduced production cost; The contact of turriform shape easily inserts between two copper pipes, and under the effect of spring leaf, contact can be fitted with the intimate of two copper pipe inner sides, and when switch short circuit, contact can produce outside repulsion, thereby makes plug-in unit reliable with being connected of vertical copper bar; In addition, vertical copper bar does not need to carry out bending and punching with being connected of main bus bar lapping plate, has simplified manufacturing procedure, process and easier for installation, and both to connect shared space less.
