Abstract
The utility model belongs to a low voltage transmission and distribution device and relates to a breaker plug-in type wiring terminal used in a drawer type breaker. The breaker plug-in type wiring terminal comprises a static wiring terminal and a movable wiring terminal. The static wiring terminal is provided with a plurality of lines of static interfaces. Every interface is provided with a static contact plate with arched longitudinal section. The movable wiring terminal is provided with a plurality of movable interfaces. The quantity and the arranged form of the movable interfaces is the same as the static interfaces. Every movable interface is provided with a movable contact plate with the arched longitudinal section. The arched surfaces of the static contact plates and the movable contact plates are arranged oppositely. The breaker plug-in type wiring terminal has low requirement on connection precision, high reliability during the plugging process and high integral intensity.
Description
Technical field
The utility model belongs to the low pressure equipment for power transmission and distribution, relates to a kind of circuit breaker plug-in connecting terminal that is used for withdrawable circuit breaker.
Background technology
Circuit breaker is used for connecting the internal circuit and the externally fed circuit of certain limit, and working is equivalent to master switch, for the convenience of Maintenance and Repair, and the normal at present withdrawable circuit breaker that uses.Withdrawable circuit breaker generally comprises two parts, the fixing drawout chassis and the breaker body of drawer type.Circuit on the drawout chassis links to each other with main circuit, and the circuit on the breaker body links to each other with external circuit.In order to connect main circuit and external circuit, general withdrawable circuit breaker all comprises moving binding post and quiet binding post, moving binding post is installed on the body of drawout chassis, link to each other with internal circuit, quiet binding post is installed on the drawout chassis, link to each other with external circuit, by the connection of finishing entire circuit that is connected of moving binding post and quiet binding post.
The binding post of existing withdrawable circuit breaker, be made up of moving binding post and quiet binding post, the connector in the connecting hole of the plug on the metal needle by quiet binding post lower end and the corresponding moving binding post continuous fetches the connection that realizes the circuit breaker secondary circuit.Because metal needle cooperates precision prescribed than higher with connector in the connecting hole, so occur the situation that dislocation, metal needle are out of shape during insertion easily, it is unreliable to contact.And the bearing that comes off easily of the plug on the quiet binding post.
Summary of the invention
Technical problem to be solved in the utility model is, at the above-mentioned defective of prior art, provides a kind of and connects that required precision is lower, insertion process reliability height, circuit breaker plug-in connecting terminal that bulk strength is high.
Circuit breaker plug-in connecting terminal of the present utility model includes a quiet binding post and a moving binding post; Quiet binding post is provided with the quiet interface of plurality of rows, is provided with a vertical section shape in each interface and is arc static contact; Moving binding post is provided with the moving interface of plurality of rows, and the quantity of moving interface is identical with quiet interface with arrangement mode, is provided with a vertical section shape in each moving interface and is arc movable contact spring; The arc surface of arching upward of static contact and movable contact spring is oppositely arranged.
Practising physiognomy of described quiet binding post and moving binding post is provided with some lead and pilot holes to cooperatively interacting.
Described quiet binding post comprises a plurality of terminal units that are arranged side by side, and a row static contact is set on each terminal unit, and each terminal unit is fixed by a cross-under pin cross-under that runs through.
Be embedded with the lead of " C " shape in the described terminal unit, an end of lead is connected with static contact, and the other end of lead is connected with external cabling.
The utility model substitutes the contact matching mode of contact pin and jack in traditional terminal structure with the cooperation of arc dynamic and static contact, because its contact range is big, even installation and cooperation position have certain deviation, still can guarantee reliable contact, thereby reduced required precision to product manufacturing and installation, improved the reliability of pegging graft; Simultaneously, because the terminal unit cross-under is fixing as a whole, thereby its structural strength height, be difficult for becoming flexible, coming off.

Embodiment
As shown in Figure 1, this circuit breaker plug-in connecting terminal is made up of quiet binding post 1 and moving binding post 2, and two pilot holes 11 are arranged on the support of quiet binding post, on the support of moving binding post two leads 21 is arranged, during insertion, lead matches with pilot hole.
As shown in Figure 2, quiet binding post is provided with the quiet interface 12 of two rows, is provided with the vertical section shape in the quiet interface and is arc static contact 13.
As shown in Figure 3, moving binding post is provided with the moving interface 22 of two rows, is provided with the vertical section shape in the moving interface and is arc movable contact spring 23.
As shown in Figure 4, a plurality of terminal units on the quiet binding post 14 are fixing as a whole by cross-under pin 15 cross-under.
Fig. 5, shown in Figure 6, the vertical section shape of static contact 13 and movable contact spring 23 is arc, and their bow top is oppositely arranged.When dynamic and static binding post connected, the arc surface of arching upward of movable contact spring and static contact was in contact with one another, because bow-shaped structural has elasticity preferably, thereby had guaranteed that contact portion has enough contact pressures.Be embedded with the lead 16 of " C " shape in the terminal unit of quiet binding post, lead one end is used for connecting static contact, and the other end of lead is used for connecting external cabling.
