Description
Technical field
The utility model relates to a kind of structure member that is applied to circuit breaker, is specifically related to a kind of plug-in connecting terminal of circuit breaker.
Background technology
Circuit breaker is used for connecting the internal circuit and the external circuit of certain limit, its effect is equivalent to master switch, circuit breaker basic structure comprise two parts, i.e. binding post and drive unit, under the drive of drive unit, binding post can be communicated with or open circuit.The binding post of circuit breaker is according to different connected modes, can be divided into wiring and plug-in connecting terminal behind wiring before the plate, the plate, adopt the circuit breaker of plug-in connecting terminal, omitted the interior necessary isolator of binding post of original general circuit breaker, improved the economy of using, bring very big convenience to operation and maintenance simultaneously, increased fail safe, reliability.
Owing to the circuit breaker that adopts plug-in connecting terminal has above-mentioned advantage, therefore all comparatively convenient in operation, maintenance and replacement, obtained using comparatively widely at present so have the circuit breaker of plug-in connecting terminal.
The circuit breaker that has plug-in connecting terminal, its binding post generally is made up of moving contact and fixed contact, and moving contact is installed on the drive unit of circuit breaker; Fixed contact is fixed in the housing of circuit breaker, and drive unit drives the moving contact reciprocating motion, inserts, extracts the connecting and disconnecting that fixed contact is realized circuit by moving contact.The reliability and stability of the connection of dynamic and static contact have significant effects for the performance of circuit breaker.
Existing fixed contact, be that the contact level is stacked forms by several, conducting strip all is housed in each contact, be provided with conducting strip in the moving contact equally, at work, moving contact moves to fixed contact under the driving of the drive unit of circuit breaker, in the slot that thereby the contact end that makes fixed contact is inserted on the moving contact with described contact end matches, thereby realize the connection of the conducting strip in the dynamic/static contact.
What be easy to expect is; because installation errors is inevitable; and circuit breaker is in working repeatedly; each parts room machine position can change a lot; therefore moving contact and the fixed contact that inserts relatively through regular meeting's occurred level produces certain alternate position spike on left and right directions; so just may cause the contact end of fixed contact can't insert in the slot of moving contact accurately; thereby the fault that causes circuit breaker; not only influence the reliability and the job stability of circuit breaker, also can cause the failure rate raising and the decline in useful life of circuit breaker.
Summary of the invention:
Goal of the invention of the present utility model, be defective at above-mentioned prior art existence, a kind of plug-in connecting terminal of circuit breaker is provided, adopt the circuit breaker of this binding post, even if in working order, there is the alternate position spike that is not more than about 3mm about the slot of moving contact and the contact terminal of fixed contact, still can guarantee the automatic adjustment of position between moving contact and fixed contact, the slot of moving contact is inserted accurately with the contact end of fixed contact to be connected, thereby the conducting strip in the dynamic/static contact is reliably connected, guaranteed the stability and the reliability of circuit breaker work.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of plug-in connecting terminal of circuit breaker, constitute by moving contact and fixed contact, described fixed contact two ends are provided with the fixed contact guide block, described moving contact two ends are provided with the moving contact guide block, the front end inboard of described fixed contact guide block is provided with fixed contact guide block inclined-plane, the described moving contact guide block front end outside is provided with outer inclined-plane, and described outer inclined-plane matches with described fixed contact guide block inclined-plane; Described moving contact guide block front end inboard also is provided with interior inclined-plane.
Further, the contact level is stacked constitutes by several for described fixed contact, and conducting strip is located in the described contact.
Further, be provided with slot in the described moving contact, described slot is divided into two groups up and down, and in any group slot, the quantity of slot matches with described contact quantity.
The beneficial effects of the utility model are:
The utility model provides a kind of plug-in connecting terminal of circuit breaker, adopt the circuit breaker of this plug-in connecting terminal, in the operating state, when moving contact is connected with fixed contact, even if there is the alternate position spike that is not more than about 3mm about the contact terminal of the slot of moving contact and fixed contact, still can guarantee the automatic adjustment of position between moving contact and fixed contact, the slot of moving contact is inserted accurately with the contact end of fixed contact to be connected, thereby the conducting strip in the dynamic/static contact is reliably connected, guaranteed the stability and the reliability of circuit breaker work.
Description of drawings:
Fig. 1 is that moving contact of the present utility model and fixed contact insert view;
Fig. 2 is a structural representation of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further explained and is illustrated:
As shown in Figure 1, 2: a kind of plug-in connecting terminal of circuit breaker, constitute by moving contact 2 and fixed contact 1, described fixed contact 1 two ends are provided with fixed contact guide block 11, described moving contact 2 two ends are provided with moving contact guide block 21, the front end inboard of described fixed contact guide block 11 is provided with fixed contact guide block inclined-plane 12, the described moving contact guide block 21 front ends outside is provided with outer inclined-plane 22, and described outer inclined-plane 22 matches with described fixed contact guide block inclined-plane 12; The front end inboard of described moving contact guide block 21 also is provided with interior inclined-plane 23.
