Abstract
The utility model relates to a hydraulic type electromagnetic breaker release which mainly solves the problems of complex assembling operation and low efficiency existing in a conventional hydraulic type electromagnetic breaker release oil cup. The hydraulic type electromagnetic breaker release is characterized in that a magnet yoke support (1) is provided with a protruding part (4) which is provided with a through hole (5); one end of the oil cup (3) passes through the through hole and is in an interference fit with the through hole (5) of the magnet yoke, and the other end is connected with an end cover (6); the two ends of the oil cup (3) corresponding to the protruding part (4) and the end cover (6) are sleeved with pads (7). The hydraulic type electromagnetic breaker release changes the fixing mode of the oil cup and the magnet yoke, and guarantees the convenient and efficient assembly of the oil cup. Besides, the hydraulic type electromagnetic breaker release is low in cost and is easy to disassemble.
Description
Technical field
The utility model relates to a kind of circuit breaker, is specifically related to a kind of fluid pressure type electro-magnetic circuit breaker release.
Background technology
The fluid pressure type electro-magnetic circuit breaker is a kind of in the circuit breaker, has the function of overcurrent and short circuit duplicate protection, and fluid pressure type electro-magnetic circuit breaker release is used for overload protection or the short-circuit protection of circuit breaker.The fluid pressure type magnetictrip comprises yoke support, solenoid and lubricating cup, and lubricating cup is fixed on the yoke support.Lubricating cup and yoke support have two kinds of fixed forms in the existing fluid pressure type electro-magnetic circuit breaker release, a kind of is that lubricating cup passes the through hole on the yoke support, then is fixed by manual welding when lubricating cup and yoke bracket assembled, the not environmental protection of this mode, cost is high.Another kind is when lubricating cup and yoke bracket assembled, the two ends of corresponding yoke rack ventilating hole are arranged with respectively elastic sheet metal on the lubricating cup, elastic sheet metal is provided with centre bore, and the centre bore interference fit of lubricating cup and elastic sheet metal is fixed on lubricating cup on the yoke support by two elastic sheet metals.This mode complex procedures, efficient is lower, and cost is high.
Summary of the invention
Need to fix by the cramping of manual welding or a plurality of metal clipss the higher problem of complicated operation, inefficiency, cost that lubricating cup produces in order to solve existing fluid pressure type magnetictrip, the utility model provides a kind of fluid pressure type electro-magnetic circuit breaker release, this fluid pressure type electro-magnetic circuit breaker release has changed the fixed form of lubricating cup and yoke support, operation is simple, cost is low, is convenient to installation and removal.
The technical solution of the utility model is: a kind of fluid pressure type electro-magnetic circuit breaker release, comprise yoke support, solenoid and lubricating cup, solenoid is wrapped in outside the lubricating cup, be provided with iron core and spring in the lubricating cup, be sealed with hydraulic oil, it is characterized in that: the yoke support is provided with boss, through hole is arranged on it, lubricating cup one end passes through hole, and interference fit between the through hole on the yoke support, the other end is connected on the end cap, by lubricating cup interference fit directly and between the through hole on the yoke support, an end of lubricating cup is fixed on the yoke support.
The technical solution of the utility model also comprises: the boss of the corresponding yoke support of lubricating cup and the two ends of end cap are overlapped respectively pad are arranged, and the external diameter of pad is not less than the external diameter of boss and end cap.

Fig. 2 is perspective view of the present utility model.
Fig. 3 is the perspective view of yoke support.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
By Fig. 1 in conjunction with Fig. 2, shown in Figure 3, a kind of fluid pressure type electro-magnetic circuit breaker release comprises yoke support (1), solenoid (2) and lubricating cup (3), solenoid (2) is wrapped in outside the lubricating cup (3), be provided with iron core and spring in the lubricating cup, and be sealed with hydraulic oil, it is characterized in that: yoke support (1) is provided with boss (4), through hole (5) is arranged on it, lubricating cup (3) one ends pass through hole (5), and interference fit between the through hole on the yoke support (5), the other end is connected on the end cap (6), and the corresponding boss of lubricating cup (3) (4) overlaps respectively with the two ends of end cap (6) pad (7).
Owing to take technique scheme, during assembling, utilize pressure apparatus, through hole (5) on the boss (4) on the yoke support (1) is interference fit on the lubricating cup (3), thereby realize that lubricating cup (3) one ends are fixed on the yoke support (1), guaranteed the axiality of the upper through hole (5) of lubricating cup (3) and yoke support (1) and stablized fixing.
The number of assembling steps of above-mentioned fluid pressure type electro-magnetic circuit breaker release is as follows: at first overlap successively Upper gasket 7, solenoid (2) and pad (7) on lubricating cup (3), then with pressure apparatus the through hole (5) on the boss (4) on the yoke support (1) is pressed into precalculated position on the lubricating cup 3; This is simple for assembly process, and parts are less, has both reduced cost, has improved again assembly and disassembly efficient.
Claims (2)
1. fluid pressure type electro-magnetic circuit breaker release, comprise yoke support (1), solenoid (2) and lubricating cup (3), solenoid (2) is wrapped in outside the lubricating cup (3), be sealed with hydraulic oil in the lubricating cup, it is characterized in that: yoke support (1) is provided with boss (4), through hole (5) is arranged on it, lubricating cup (3) one ends pass through hole (5), and interference fit between the through hole on the yoke support (5), the other end is connected on the end cap (6), and the corresponding boss of lubricating cup (3) (4) overlaps respectively with the two ends of end cap (6) pad (7).
2. fluid pressure type electro-magnetic circuit breaker release according to claim 1, it is characterized in that: the external diameter of pad (7) is not less than the external diameter of boss (4) and end cap (6).
