Abstract
The utility model relates to an electromagnetic type integrative leakage protector, which comprises a fixed support that is fixed on a base, a moving contact assembly that is provided with a spacer plate at one end and is in pin connection with the fixed support through a rotating shaft, and a reset spring. The utility model is characterized in that a spacer pin which penetrates through the fixed support is arranged in the front or on the top of the spacer plate of the moving contact assembly, and the reset spring is arranged between the fixed support and the spacer plate of moving contact assembly. Due to the adoption of the spacer pin which penetrates through the fixed support and is taken as a spacer mechanism, the assembly technologies and procedures are simplified on one hand, so that the production rate of the entire electromagnetic type leakage protector is improved; the spacer pin can not deform the fixed support on the other hand, and the flexible rotation of the moving contact assembly is ensured, so that the action sensitivity and reliability of the entire integrative protector is ensured, and the qualification rate of products is increased. The utility model can be widely used in the field of manufacturing the electromagnetic type leakage protectors with various specifications and models.
Description
Technical field
The utility model belongs to the emergency protective device field, relates in particular to a kind of operation or relieving mechanism that is used for the electromagnetic leakage comprehensive protection device.
Background technology
The electromagnetic leakage comprehensive protection device; be a kind of power supply unit, supply line are implemented comprehensive integrated protection and have the comprehensive leakage protective device of on-load switch function concurrently; because of it has supply voltage characteristic there is not influence; ambient temperature is very little to properties influence; withstand voltage impact capacity is strong, and external magnetic field disturbs little, advantages of simple structure and simple; both can be used as the switch or the circuit breaker of on-load, can do the circuit synthesis earth leakage protective device again.
The operating mechanism of existing electromagnetic leakage protector; generally include the electromagnetic actuation/releasing unit and the switch contacts system that are installed on the base; wherein electromagnetic actuation/releasing unit is formed by being fixed on iron core on the base and the magnet exciting coil that is positioned on the iron core, and the switch contacts system is then main to be had limiting plate and the moving contact component by rotation axis and fixed support pin joint, be fixed on deciding contact assembly and being used to make back-moving spring that moving contact component can reset etc. to form on the base by being fixed on fixed support, an end on the base.
For the moving contact component that is installed on the fixed support can be moved within the limits prescribed, on fixed support, need to be provided with, to install a spacing member, the spacing flat iron bar that existing spacing member usually adopts an approximate door type or ∏ font and has a fixed screw holes serves as spacing member, in order to the actuating range of restriction moving contact component.
But because often there is certain error in its machining accuracy; many (the empiecements of number of assembling steps; to the hole; the location; fix with screw; regulate position back of the body or the like); be difficult for the influence of assembling and assembling required time than factors such as length; the assembling work efficiency of spacing flat iron bar is lower; waste time and energy and the limit effect instability; it or not the screw hole misalignment on spacing flat iron bar and the fixed support and cause and to tumble in; be exactly because of the dimensional discrepancy of flat iron bar big; cause fixed support to deform; and then have influence on the flexible rotation of moving contact component; seriously restricted the assembling of whole electromagnetic leakage protector; the qualification rate of assembling speed and product, and then have influence on the overall economic efficiency of whole enterprise.
The utility model content
Technical problem to be solved in the utility model provides a kind of limit effect that can guarantee moving contact component; can realize again easy to assembly, quick, be convenient to enhance productivity, can also guarantee the operating sensitivity of whole comprehensive protection device and the electromagnetic leakage comprehensive protection device of reliability.
The technical solution of the utility model is: a kind of electromagnetic leakage comprehensive protection device is provided, comprise that the fixed support, the end that are fixed on the base have limiting plate and moving contact component and back-moving spring by rotation axis and fixed support pin joint, it is characterized in that the place ahead of moving contact component limiting plate or above, be provided with one and pass support bracket fastened spacer pin; Described back-moving spring is arranged between the limiting plate and fixed support of moving contact component.
The cross section of its described spacer pin is circle, ellipse, triangle or rectangle.
Compared with the prior art, the utility model has the advantages that:
1. spacer pin is quick for installation, convenient, makes the assembling of whole electromagnetic leakage protector, assembling speed be greatly improved;
2. replace original spacing band iron structure with the spacer pin structure; manufacturing, processing and the assembling process of spacing member had both been simplified; can not cause fixed support to deform again, guarantee the flexible rotation of moving contact component, and then guarantee the operating sensitivity and the reliability of whole comprehensive protection device.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described further.
Fig. 1 is a structural representation of the present utility model.
1 is base among the figure, and 2 is fixed support, and 3 is rotation axis, and 4 is limiting plate, and 5 is moving contact component, and 6 is spacer pin, and 7 is back-moving spring, and 8 is electromagnetic actuation/releasing unit.
Embodiment
Among Fig. 1, fixed support 2 is fixed on the base 1, one end of moving contact component 5 has limiting plate 3, moving contact component is by rotation axis 4 and fixed support pin joint, the place ahead of moving contact component limiting plate or above (be horizontal mounting means among the figure, so be the place ahead at limiting plate, if adopt vertical mounting means, then whole base, fixed support and moving contact component should rotate counterclockwise 90 degree, so be above limiting plate), be provided with one and pass support bracket fastened spacer pin 7; Back-moving spring 6 is arranged between the limiting plate and fixed support of moving contact component.
When electromagnetic actuation/releasing unit 8 no powers, moving contact component 5 is in release condition (upwards rising for moving contact component among the figure) under the effect of back-moving spring 6, its limiting plate 3 is subjected to the restriction of spacer pin 7, make whole moving contact component be in a fixing allocation really, main circuit is disconnected.
When 8 energisings of electromagnetic actuation/releasing unit, moving contact component is in attracting state (moving downward for moving contact component among the figure) under the effect of electromagnet, its limiting plate 3 is with back-moving spring 7 compressions, each moving contact contact contacts with the contact assembly (not shown) of deciding on being fixed on base, and main circuit is switched on.
Owing to adopt and pass support bracket fastened spacer pin as position-limit mechanism; packaging technology and step have been simplified on the one hand; make the speed of production of whole electromagnetic leakage protector be greatly improved; on the other hand; spacer pin can not cause fixed support to deform; guarantee the flexible rotation of moving contact component, and then guaranteed the operating sensitivity and the reliability of whole comprehensive protection device, improved the qualification rate of product.
The utility model can be widely used in the manufacturing field of all size model electromagnetic leakage protector.
