The utility model content
In order to overcome deficiency and the defective in the background technology, the utility model provides a kind of breaker connection device, and it is easily loosening in lead access back existence mainly to solve existing breaker connection device, stable bad problem.
The technical solution of the utility model is: a kind of breaker connection device, comprise bolt and binding clip, described binding clip is the shaped as frame structure, described binding clip upper end is provided with screwed hole, described bolt is connected with binding clip by screwed hole, it is characterized in that: the side frame of described binding clip and boundary frame area inwall junction are provided with retaining convex rib, and the described retaining convex rib outside is provided with the inclined-plane corresponding with screwed hole.
The middle part of the boundary frame area of described binding clip is bent to form v-shaped structure downwards.
The V-arrangement knuckle place that the middle part of the boundary frame area of described binding clip is bent to form downwards, inwall is provided with some spacing clamps.
Also include terminal block, described terminal block bottom is bent into U-shaped, described U-shaped kink upper end is for being used for connecting the top board of binding clip, the lower end is for connecting the base plate of lead, described binding clip is socketed on the base plate, offer pilot hole on the described top board, described bolt passes pilot hole and is threaded with binding clip.
The cross section of described retaining convex rib is triangular in shape, fixedlys connected with described binding clip in the two sides of described retaining convex rib.
Described base plate lower surface is provided with some transversely arranged grooves.
The beneficial effects of the utility model: owing to take such scheme, a kind of breaker connection device of the present utility model, the binding clip bottom arranges the retaining convex rib of projection and has filled up the side frame of binding clip and the space that boundary frame area inwall junction forms, be conducive to reliability when connecting the small bore lead and the fastness of wiring, has the firmness height, good stability, the service-strong effect.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the STRUCTURE DECOMPOSITION figure of Fig. 1.
Fig. 3 is the front view of binding clip among Fig. 1.
Fig. 4 is the structural representation of terminal block among Fig. 1.
Fig. 5 is assembling schematic diagram of the present utility model.
Among the figure, binding clip 1, side frame 11, boundary frame area 12, retaining convex rib 13, spacing clamp 14, screwed hole 2, bolt 3, terminal block 4, top board 41, base plate 42, groove 421, pilot hole 43.
Embodiment
At accompanying drawing embodiment of the present utility model is described further below:
A kind of breaker connection device, comprise bolt 3 and binding clip 1, described binding clip 1 is the shaped as frame structure, described binding clip 1 upper end is provided with screwed hole 2, described bolt 3 is connected with binding clip 1 by screwed hole 2, the side frame 11 of described binding clip is provided with retaining convex rib 13 with the junction, inwall place of boundary frame area 12, and described retaining convex rib 13 outsides are provided with the inclined-plane corresponding with screwed hole 2.The binding clip bottom arranges the retaining convex rib of projection and has filled up the side frame of binding clip and the space that boundary frame area inwall junction forms, the lead nature drew in to the binding clip center when project organization of retaining convex rib ramp made wiring, be conducive to reliability when connecting the small bore lead and the fastness of wiring, has the firmness height, good stability, the service-strong effect.
The middle part of the boundary frame area 12 of described binding clip 1 is bent to form v-shaped structure downwards.The project organization of V-shape makes the lead nature draw in to the binding clip center when helping wiring, have easy-to-connect, good stability, service-strong characteristics.
The V-arrangement knuckle place that the middle part of the boundary frame area 12 of described binding clip 1 is bent to form downwards, inwall is provided with some spacing clamps 14.Make the frictional force change of lower surface big as two so spacing clamps preferably are set, lead or bus-bar insert the back difficult drop-off, and installation is firm, reliable and stable effect.
Also include terminal block 4, described terminal block 4 bottoms are bent into U-shaped, described U-shaped kink upper end is for being used for connecting the top board 41 of binding clip 1, the lower end is for connecting the base plate 42 of lead, described binding clip 1 is socketed on the base plate 42, offer pilot hole 43 on the described top board 41, described bolt 3 passes pilot hole 43 and is threaded with binding clip 1.When circuit breaker uses, if insert lead, lead is placed between base plate and the binding clip, turns bolt, drive binding clip and upwards promote, thereby lead is clamped by base plate and binding clip, make lead be close to base plate; When needing to insert bus-bar, the standard bus-bar is stuck between top board and the terminal screw, tightens connection bolt, make bus-bar be close to described top board, can connect lead, can connect bus-bar again, the mode of connection easily is provided, has had good stability, effect easy to assembly.
