Abstract
The utility model discloses an imperforate connecting structure of the cooper-covered aluminum mother trunking, which comprises at least three insulating separating pieces, arranged side-by-side. The two adjacent insulating separating pieces leave a gap into which conducting substances are inserted. The utility model is characterized in that: at least one concave opening is respectively positioned on the sides of each separating piece near the two sides of the inserting direction of the conductor substance. Each set of concave openings in the same array forms a trough extending along the direction, along which the separating pieces are arranged side-by-side. Each trough is erected with a movement-stopping insulating pipe. A position tight locking structure is positioned between the movement-stopping insulating pipe and the insulating separating pieces. The connecting end opening of the mother trunking adopts an imperforated connecting structure, is convenient and flexible to assemble and detach, has small contact resistance and low temperature, guarantees a good contact property, operates safely and reliably, and meets the heavy current power distribution needs of high rise or large scale squares, residential buildings, industrial and mining factories and so on.

A kind of no hole connection structure of copper coated aluminum bus wire casing, comprise at least three insulation spacers that are arranged side by side, leave the gap of inserting between adjacent two insulation spacers for electric conductor, it is characterized in that: on each spacer side of electric conductor direction of insertion both sides, be respectively equipped with at least one recess, the recess formation one of every group of same column is arranged side by side direction along the groove of stretching along spacer, set up a holder stop insulated tube in each groove, be provided with a positioning and locking structure between holder stop insulated tube and insulation spacer.
Above-mentioned positioning and locking structure is made up of brute spring sheet and cover plate, and brute spring sheet and cover plate lock mutually by holder stop insulated tube.
Above-mentioned spacer recess respectively has two on both sides up and down.
The spacer that above-mentioned insulation spacer is made for the polyester glass fiber reinforcing material.
At least one side of above-mentioned each insulation spacer is provided with a circle projection.
One end of above-mentioned brute spring sheet is provided with manhole, and the other end is provided with U type recess.
Said fixing seat stop insulated tube two ends are provided with bolt arrangement.
Above-mentioned cover plate is provided with and the corresponding semi-circular indentation of insulation spacer recess.
The place, connectivity port of above-mentioned per two joint bus ducts also is provided with connecting rod.
No hole connection structure is adopted in the bus duct connectivity port, and all easily flexibly, contact resistance is little, temperature rise is low in installation and removal, guarantees that contact performance is good, safe and reliable to operation, satisfies big electric current distribution needs such as high level or large-scale square, domestic premises and industrial and mineral factory building.
In order to understand the utility model more clearly, hereinafter with reference to description of drawings embodiment of the present utility model.

Embodiment
Shown in Fig. 1,2, the utility model comprises at least three insulation spacers that are arranged side by side 4, and 4 of adjacent two insulation spacers leave the gap of inserting for electric conductor 2, and the quantity of insulation spacer 4 is Duoed one at least than electric conductor 2.Insulation spacer 4 adopts the polyester glass fiber reinforcing material to make, on each spacer 4 side of electric conductor 2 direction of insertion both sides, respectively be provided with two recesses 5, be provided with a circle projection 8 in two insulation spacer 4 one sides near shell 1, middle insulation spacer 4 two sides all are provided with a circle projection 8.The recess formation one of every group of same column is arranged side by side direction along the groove of stretching along spacer, sets up a holder stop insulated tube 6 in each groove.Holder stop insulated tube 6 two ends are provided with bolt arrangement.The both sides of insulation spacer 4 and top also are provided with brute spring sheet 7 and cover plate 9 side by side, brute spring sheet 7 and cover plate 9 can lock with holder stop insulated tube 6 mutually by the bolt arrangement of holder stop insulated tube 6, thereby insulation spacer 4 and electric conductor 2 are interfixed, reach the purpose that electric conductor connects contact.
According to shown in Figure 3, brute spring sheet 7 is two-sided pressure manganese steel spring leaf, and an end is provided with manhole 72, and the other end is provided with U type recess 71.
According to shown in Figure 4, cover plate 9 is that [structure, both sides are provided with and insulation spacer 4 recesses 5 corresponding semi-circular indentation 91.
According to shown in Figure 5, when using this copper coated aluminum bus wire casing, three row's copper cover aluminium electric conductor 2 and interfix with shell 1 by insulating support 3.In the grafting port, the copper of two joint bus ducts covers aluminium electric conductor 2 and contacts, pin the manhole 72 of spring leaf earlier with holder stop insulated tube 6, suitable space is left in the centre, cover aluminium electric conductor 2 both sides at copper again and load onto insulation spacer 4 side by side, holder stop insulated tube 6 blocks the semi-circular indentation 5 of insulation spacer 4 bottoms, block the semi-circular indentation 5 of another side equally with holder stop insulated tube 6 on the top of insulation spacer 4, tighten up the U type groove 71 of spring leaf 7 simultaneously, load onto cover plate 9, with bolt cover plate 9 and brute spring sheet 7 and holder stop insulated tube 6 are locked mutually, thereby fix insulation spacer 4 and copper covers aluminium electric conductor 2.At last, utilize metal connecting rod 11 that two joint bus ducts are connected and fixed, cover sheath top plate 10 and promptly finish assembling of this bus duct.
The grafting port of the present utility model connection of need not punching, be connected to butt joint between the electric conductor 2, respectively there is a spacer 4 electric conductor 2 both sides, the pressure that produces by brute spring sheet 7 makes spacer 4 closely contact (contact resistance is little, temperature rise is low) with electric conductor 2, and electric current circulates between different conductor by both sides spacer 4.During different electric conductors 2 butt joints, the space compensation variable quantity of 10mm is left in the gap of horizontal connector, and electric conductor 2 need not be at the horizontal and vertical thermal expansion expansion joint that is provided with because of being subjected to thermogenetic self expansion can free shrink.Brute spring sheet 7 is even in the pressure distribution that spacer 4 parts produce simultaneously, and compensates the contact pressure variation that causes because of breathing, guarantees contact performance long-term stability, reliable, and service free is safeguarded.It is all very convenient that the utility model also has another advantage to mount and dismount exactly.
