Abstract
Disclosed in the utility model is a relay with high safety performance. The relay comprises a housing (1), a pedestal (2), and a yoke (7), wherein the housing (1) is installed on the pedestal (2) and the yoke (7) is installed in an inner cavity of the housing. Bosses (4) are arranged at the outer wall of the yoke (7); and limiting holes (5) are arranged at the upper end surface (3) of the housing (1). According to the utility model, because the bosses are arranged at the outer surface of the yoke, direct contact of the yoke and the housing can be avoided and the collision force can be reduced, thereby protecting the yoke from being damaged. Besides, due to the arrangement of the limiting holes on the housing, the positioning effect during the installation process can be realized, thereby ensuring that the relay can be installed on a machine rapidly and accurately.
Description
Technical field
The utility model relates to a kind of relay, is specifically related to a kind of relay of high safety performance.
Background technology
Relay is one of electric component the most frequently used in people's daily life, and its structural behaviour and fail safe have significant impact to daily life.Relay primary structure in the market comprises coil, yoke, plectrum, the movable contact utmost point, the stationary contact utmost point, and movable contact utmost point pushing block, substrate, clamp, plectrum are fixed on the substrate and can rotate.
The relay of prior art has the following disadvantages, because the housing upper surface is the plane, without positioner, on automatic assembly production line, easily makes mistakes, and produces rigging error.When yoke is installed, perhaps in the transportation, affect because being subjected to external force in addition, yoke can be run into housing and cause distortion, thereby affects the performance of relay.
The utility model content
The technical problem that (one) will solve
The technical problems to be solved in the utility model provides a kind of relay of high safety performance, and it is difficult for making the yoke distortion, and in machine relay can be installed accurately and easily.
(2) technical scheme
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: the relay that a kind of high safety performance is provided, it comprises housing (1), base (2), yoke (7), described housing (1) is installed on the described base (2), described yoke (7) is installed in described housing (1) inner chamber, the outer wall of described yoke (7) is provided with boss (4), and the upper surface (3) of described housing (1) is provided with spacing hole (5).
As preferably, described spacing hole (5) is blind hole.
As preferably, the quantity of described spacing hole (5) is 2.
As preferably, be provided with chamfering (6) outside the described housing (1).
(3) beneficial effect
The utility model is compared to prior art, and it has following beneficial effect: owing to being provided with boss at the yoke outer surface, can avoid yoke directly to contact with housing, extenuate impact force, thereby the protection yoke is not impaired; Owing to being provided with spacing hole in the housing upper surface, in installation process, play positioning action, can guarantee that relay is installed on the machine rapidly and accurately.
Description of drawings
Fig. 1 is the structural representation of the relay of high safety performance of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
The relay of a kind of high safety performance as depicted in figs. 1 and 2, it comprises housing 1, base 2, yoke 7, housing 1 is installed on the base 2, yoke 7 is installed in housing 1 inner chamber, the outer wall of yoke 7 is provided with boss 4, the upper surface 3 of housing 1 is provided with spacing hole 5, and spacing hole 5 is blind hole, and the quantity of spacing hole 5 is 2.Housing 1 outside is provided with chamfering 6, and the setting of chamfering has avoided the acute angle on the housing to occur, and has improved casing rigidity, makes relay more safe and reliable in installation process, is unlikely to the structure that slight collision has just damaged housing.
The utility model can avoid yoke directly to contact with housing owing to being provided with boss at the yoke outer surface, extenuates impact force, thereby the protection yoke is not impaired; Owing to being provided with spacing hole in the housing upper surface, in installation process, play positioning action, can guarantee that relay is installed on the machine rapidly and accurately.
The above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
