Abstract
The utility model discloses a coil frame of a double-coil relay. The coil frame comprises a bobbin, one end of the bobbin is provided with a first baffle plate, the first baffle plate is equipped with a first lead-out pin, a second lead-out pin and a third lead-out pin, one surface of the inner side of the first baffle plate between the bobbin and the second lead-out pin is provided with a groove used for guiding an enameled wire, one end of the groove is connected to the bobbin, and the other end of the groove is connected to the second lead-out pin. Due to the special design of the baffle plate at one end of the bobbin of the coil frame, the first turn and the last turn of the enameled wire can be isolated effectively, and the disadvantage caused by the fact that the first turn and the last turn of an enameled wire are lapped in the prior art is eliminated.
Description
Technical field
The utility model relates to a kind of relay, particularly relates to a kind of bobbin of double-wound relay.
Background technology
Relay is the automatic switch element with isolation features, is widely used in the fields such as communication, automobile, control automatically, household electrical appliance, is one of most important control element.
A kind of double-wound relay of prior art, on the reel of bobbin, to be wound with inner ring enamelled wire and outer ring enamelled wire, the bobbin of this structure is typically provided with three leading foots, the first leading foot and the second leading foot are used for being wound around inner ring enamelled wire, the second leading foot and the 3rd leading foot are used for being wound around outer ring enamelled wire, during coiling enamelled wire, if its first circle line and last astragal directly hang together (or being close together), owing to inevitably can forming friction between the enamelled wire hanging together, easily by the insulating varnish film destroy of enamelled wire surface, form direct short-circuit between enamelled wire first circle line and last astragal, and because the voltage difference between enamelled wire first circle line and last astragal is in fact no better than the voltage being added on enamelled wire winding, therefore it is larger to work as the voltage ratio being added on enamelled wire winding, and when enamelled wire winding first circle line and last astragal directly hang together, be easy between the first circle line of enamelled wire winding and last astragal, directly form voltage breakdown, cause equipment fault.
Utility model content
The purpose of this utility model is to overcome the deficiency of prior art, a kind of bobbin of double-wound relay is provided, the particular design of the baffle plate by the reel one end to bobbin, can effectively the last astragal of the first circle line of enamelled wire and enamelled wire be kept apart, avoid in prior art the first circle line of enamelled wire and the last astragal of enamelled wire the caused drawback that hangs together.
The utility model solves the technical scheme that its technical problem adopts: a kind of bobbin of double-wound relay, comprise reel, one end of reel is provided with the first baffle plate, and the first leading foot, the second leading foot and the 3rd leading foot are housed respectively on the first baffle plate; The inner side one side of the first baffle plate between reel and the second leading foot is also provided with for guiding the groove of enamelled wire, and one end of groove is connected to reel, and the other end of groove passes to the second leading foot.
In the inner side of the first baffle plate, be simultaneously provided with by reel and extend the boss to the second leading foot, at a side of boss, be provided with Yi Tuoqiang, described in being surrounded by holder wall and boss, be used for guiding the groove of enamelled wire.
Inner side at the first baffle plate is simultaneously provided with swash plate, and this swash plate is gradually outward-dipping by reel to the second leading foot direction; Described boss and holder wall are located at respectively the centre of swash plate and a side of swash plate.
The inner side one side of the first baffle plate between the first leading foot and reel is also equipped with can block first cover plate of pressing enamelled wire.
The upper surface of the upper surface of described boss and holder wall is not higher than the upper surface of the first cover plate.
The inner side one side of the first baffle plate between the 3rd leading foot and reel is also equipped with can block second cover plate of pressing enamelled wire.
The upper surface of the upper surface of described boss and holder wall is not higher than the upper surface of the second cover plate.
The bobbin of a kind of double-wound relay of the present utility model, when enamelled wire, first coiling inner ring, after enamelled wire is first wound around on the first leading foot, from the first cover plate below, pass, on reel, be wound around after the required number of turns counterclockwise, via groove, be drawn out to the second leading foot, after being wound around, complete inner ring coiling on the second leading foot.During coiling outer ring, enamelled wire is guided on reel via groove after being wound around on the second leading foot, on reel, be wound around clockwise after the required number of turns, via boss, holder wall is guided to the second cover plate below, through the second cover plate below, after being wound around, complete the coiling of outer ring on the 3rd leading foot.Because boss becomes the groove that can guide enamelled wire with holder circummure, the bottom land of groove is swash plate, one end of groove is connected to reel, the other end of groove passes to the second leading foot, like this when the first circle of coiling outer ring enamelled wire, enamelled wire is on the swash plate riding in groove, when coiling is enclosed to the end of its outer ring enamelled wire, due to the effect that has boss with holder wall, the enamelled wire of end circle can be held up, between first circle line and last astragal, form air gap, thereby avoid the first circle line of outer ring winding and last astragal directly to hang together and all rough sledding of forming.
The beneficial effects of the utility model are:
Owing to having adopted the inner side one side of the first baffle plate between reel and the second leading foot to be also provided with for guiding the groove of enamelled wire, one end of groove is connected to reel, and the other end of groove passes to the second leading foot.Above-mentioned this structure can be kept apart the last astragal of the first circle line of enamelled wire and enamelled wire effectively, has eliminated in prior art the first circle line of enamelled wire and the last astragal of enamelled wire the caused drawback that hangs together.
Below in conjunction with drawings and Examples, the utility model is described in further detail; But the bobbin of a kind of double-wound relay of the present utility model is not limited to embodiment.
