Convenient.
Embodiment 3
As Figure 7-9, the breaker assembly of the present embodiment, including breaker, cable and realize described breaker
With the termination 2 of described cable electrical connection, described termination 2 is the termination 2 described in embodiment 1, described disconnected
Road device is the breaker described in embodiment 2.
In the present embodiment, described terminal plate 10 is just to the both sides being arranged on described breaker body, described termination 2
It is two, coordinate with described terminal plate 10 grafting being positioned at described breaker body both sides respectively；Described ridge 21a is towards breaker
Being provided with groove 210, the convex tendon 12 on described breaker lateral wall on the sidewall of body, described convex tendon 12 coordinates embedded described recessed
In groove 210, being equipped with of described convex tendon 12 and described groove 210 so that the installation between breaker and junction block 21 is more
Firm, it is to avoid occur relative position to move during extraneous concussion, further increase the stability of mechanism, and use insertion to pull out
The connected mode going out, easy for installation, time saving and energy saving.
In the present embodiment, described cable terminals 3 are set to a platy structure, and described platy structure has been opened
Circular hole 30, described circular hole 30 is suitable for being inserted on described boss 220, connects simple and convenient.
The connection principle of the breaker assembly of the present embodiment is as described below:
As shown in Fig. 1 and Fig. 6-7, two described terminations 2, when installing breaker of plastic casing, are first passed through four by user
Described gag lever post 24 is fixed on the described mounting base A of power distribution cabinet, then, as it is shown in figure 5, by described cable terminals 3
It is inserted on the described boss 220 on the described positioning sliding block 22 of described termination 2, by the described boss of described positioning sliding block 22
220 and the circular hole 30 of described cable terminals 3 position, owing to described positioning sliding block 22 is by the work of the described stage clip 26 of bottom
Firmly, described positioning sliding block 22 can upwards push up and is arranged on described mounting groove sidewall and/or is arranged on described ridge 21a sidewall
On locating part.
When inserting described cable terminals 3, need to press...with one's finger described positioning sliding block 22, just can complete described
