Description
Technical field
The present invention relates to a kind of electromagnetic relay, more particularly to a kind of electromagnetic relay bobbin component.
Background technology
Relay is a kind of using extensive electronic component, and it is widely used in household electrical appliance, automobile, Industry Control, electricity
The fields such as Force system, communication device, one of the microminaturization of electromagnetic relay, high-power demand for development its developing direction.
In electromagnetic relay, bobbin is a basic parts in electromagnetic relay, one or more windings and
Bobbin etc. constitutes coil, when have in coil electric current by when produce magnetic flux to make magnetic circuit in movable member move, and drive drive
Dynamic mechanism urges contact system switching circuit, therefore, relay power switched is directly proportional to the inductance value of coil, and then and coil
Number of ampere turns is directly proportional, and also the volume to the magnetic conduction parts in electromagnetic system is directly proportional, it is clear that coil turn is more, magnetic circuit is led
Magnetic parts volume is bigger, take up room more.And at present electromagnetic relay typically use bobbin include reel and
It is located at the terminal pin mounting seat of reel one end（If Chinese Authorization Notice No. is the B of CN 103426688《A kind of twin coil after
The bobbin of electrical equipment》In accompanying drawing 1）, mounting hole is set in terminal pin mounting seat, terminal pin is from the inner side of terminal pin mounting seat
Extend to the outside of terminal pin mounting seat through mounting hole, so that realize being fixedly connected with bobbin, in terminal pin mounting seat
The part of inner side twines end line portion for terminal pin, and the part at terminal pin on the outside of terminal pin mounting seat is leading foot, coil
Input or output end are respectively wound around the twining in end line portion of corresponding terminal pin.The relay coil support group of this structure type
The shortcoming of part is, because the end line portion that twines of terminal pin occupies enamel-covered wire winding space, to have impact on the relay under certain volume restriction
The high-power of device.Current electromagnetic relay does not extend out the installation of terminal pin mounting seat medial surface also using a kind of terminal pin
Mode, as shown in accompanying drawing 1, Fig. 2, there is the risk that terminal pin is pulled out, or coil in the bobbin component of this structure type
The contact engaging and separating force of terminal pin is difficult to meet requirement of the IEC 61810-2-21 standards on relay leading foot intensity.
The content of the invention
The technical problems to be solved by the invention are to provide one kind can greatly promote terminal pin contact engaging and separating force, and can be
Increase the bobbin component of the electromagnetic relay in magnetic circuit system space under conditions of restriction appearance and size.
The present invention solve the technical scheme that is used of above-mentioned technical problem for：A kind of bobbin component of electromagnetic relay,
Including bobbin and terminal pin, terminal pin mounting seat is provided with described bobbin, is set in described terminal pin mounting seat
Have a draw-in groove, described terminal pin includes Access Division, twine end line portion and with described Access Division and described to twine end line portion even vertical
Leading foot, described Access Division dorsad sets with the described end line portion that twines, and described draw-in groove notch is located at described terminal pin
The side of installation portion, the Access Division of described terminal pin and described draw-in groove phase clamping.
Described Access Division, described twine end line portion and described leading foot integrally connected, so, the structure phase of terminal pin
To simple, volume and being optimal of electric property.
The vertical section of described Access Division, the described vertical section for twining end line portion are equal with the vertical section of described leading foot
OK, the terminal pin of this form is easy to process, when bobbin component loads the pedestal of relay, can use from pedestal side
Clamping is installed after propulsion, easy to operate.
In order to increase the stability of terminal pin and bobbin clamping, described Access Division is integrally T-shaped.
The vertical section of described leading foot mutually hangs down with the vertical section or the described end line portion vertical section that twines of described Access Division
Directly, so, after the Access Division of terminal pin and draw-in groove phase clamping, Access Division reaches maximum with the perpendicular contact area of leading foot,
So that the installation stable connection of terminal pin and bobbin, the contact engaging and separating force that terminal pin can bear also is maximized.
Described bobbin includes reel and is arranged on first flange and the second flange at described reel two ends, institute
The terminal pin mounting seat stated is integrally attached to the lower end of the first described flange, and the arranged on left and right sides of the first described flange is distinguished
It is wholely set to install the left installing plate and right installing plate of disk pack, the length a of described terminal pin mounting seat is less than described
Left installing plate and described right installing plate length b, the bobbin component of this form is applied to magnetic latching relay, so
Terminal pin is that the space for being not take up disk pack does not increase relay appearance and size in the horizontal direction yet.
The first described flange inner face is provided with the first wire lead slot that multiple one end are connected to described reel, each institute
The other end of the first wire lead slot stated and the second corresponding lead being arranged on the lateral surface of described terminal pin mounting seat
One end of groove is connected, and the second wire lead slot other end described in each is passed to by corresponding terminal pin, so, coil input end or
Output end from reel to terminal pin when twining end line portion under the guiding of the first wire lead slot and the second wire lead slot, it is in good order,
When bobbin component and relay base are assembled coil will not be squeezed and break or enamel-covered wire abrasion after cause coil short.
Compared with prior art, the advantage of the invention is that：Due to the terminal pin in bobbin component include Access Division, twine
End line portion and with Access Division and twine the even vertical leading foot in end line portion, Access Division is dorsad set with end line portion is twined, and draw-in groove notch sets
In the side of terminal pin installation portion, Access Division and the draw-in groove phase clamping of terminal pin, so, terminal pin does not stretch out the lead of bobbin
The inner side of pin mounting seat, is not take up the space of other magnetic conduction parts or coil in electromagnetic system, under conditions of space is limited,
The occupancy volume of magnetic conduction parts or coil can be relatively large, and the magnetic flux in the inductance value and magnetic circuit of coil is also larger, so
The contact load ability of relay can accordingly increase, so as to realize the high-power of relay；In addition, during using relay,
Terminal pin does not exist the risk being drawn out by plug yet, considerably beyond IEC 61810-2-21 standards on relay leading foot
The requirement of intensity.
