Abstract
The invention discloses an alternating-current-direct-current conversion electromagnet coil connecting structure which comprises a coil, a coil shell for covering the coil and a printed circuit board (PCB), and further comprises a connecting plate. The connecting plate is fixed on the coil shell; and the PCB is fixed on the connecting plate. The alternating current-direct current conversion electromagnet coil connecting structure improves the quality of the product so as to ensure that the product is durable and capable of being used in severe environment; the alternating-current-direct-current conversion electromagnet coil connecting structure saves time because a large current needs exerting, ensures that electric resistance welding can be finished within two seconds averagely with a low voltage current, and reduces processing steps, wherein original tin soldering is conducted after varnished wires are removed, and therefore the whole assembling steps are increased, and costs are indirectly increased; and the alternating current-direct-current-conversion electromagnet coil connecting structure is high in temperature resistance level, and capable of keeping physical characteristics and chemical characteristics of the product under a high-temperature condition.
Description
Technical field
The present invention relates to a kind of alternating current-direct current and transform electromagnet, relate in particular to a kind of alternating current-direct current and transform the electromagnet coil syndeton.
Background technology
Alternating current-direct current transforms electromagnet must realize its function by diode and some other electronic components in the process that realizes AC-DC conversion, and alterating and direct current magnet mainly is made up of support, coil, shell, wiring board, the first-class part of connection, wherein, how coil is connected with wiring board and is perplexing people always.At present, generally adopt the soldering mode that coil and wiring board are coupled together, the resin that injects low temperature then in the circuit board makes its insulation, improves its sealing.But along with improving constantly of environment for use and useful life, this connected mode can't satisfy the demands.Because the in-molded technology of general at present employing during the wiring board injection moulding, temperature can reach about 250 degree, and soldering just is in molten condition about 180 degree, so the junction of coil and wiring board is easy to fusion and disconnects, cause line to be dashed, influence the stability of product.Simultaneously, what alternating current-direct current transformed the electromagnet use is enamelled wire, and the outside has one deck coat of paint to coat, and therefore when connecting, must remove enamelled coating earlier, could weld, and causes technology loaded down with trivial details, inefficiency.
Summary of the invention
In order to overcome above-mentioned defective, the invention provides a kind of alternating current-direct current and transform the electromagnet coil syndeton, can high temperature resistantly impact, it is bad by the product that dashes phenomenon and cause can not line to occur.
The present invention for the technical scheme that solves its technical problem and adopt is: a kind of alternating current-direct current transforms the electromagnet coil syndeton, comprise coil, this coil is coated its interior coil case and pcb board, other is provided with a plate, this connecting plate is fixed on the described coil case, and described pcb board is fixed on this connecting plate; Also be respectively equipped with an electrical connection PIN pin in the and arranged on left and right sides position of described PCB, this each PIN pin has a bending hook portion, and the both ends of described coil are passed from the bending hook portion of two PIN pin respectively and formed one by electric resistance welding and the welding of described bending hook portion.
As a further improvement on the present invention, the end away from described pcb board of described each PIN pin also is provided with a fixed part that is used for the winding around head.
The invention has the beneficial effects as follows:
1. promoted the quality quality of product: more durable, can in worse environment, use.
2. save time: as long as electric resistance welding applies a big electric current, the electric current of low-voltage just can be finished one among the average 2S.
3. reduce processing step: original soldering need be removed enamelled wire, soldering then, and number of assembling steps increases so really, increases cost indirectly.
4. temperature resistant grade is higher: can keep its physics and chemical characteristic under hot conditions.
Description of drawings
Fig. 1 is a structural representation of the present invention.
In conjunction with the accompanying drawings, make the following instructions:
1---coil case 2---pcb board
3---connecting plate 4---PIN pin
41---bending hook portion 42---fixed part
Embodiment
In conjunction with the accompanying drawings, the present invention is elaborated, but protection scope of the present invention is not limited to following embodiment, promptly the simple equivalent of being done with the present patent application claim and description in every case changes and modifies, and all still belongs within the patent covering scope of the present invention.
As shown in Figure 1, a kind of alternating current-direct current transforms the electromagnet coil syndeton, comprises coil, this coil is coated its interior coil case 1 and pcb board 2, and other is provided with a plate 3, this connecting plate is fixed on the described coil case, and described pcb board is fixed on this connecting plate; Also being respectively equipped with one in the and arranged on left and right sides position of described PCB is electrically connected with PIN pin 4, this each PIN pin has a bending hook portion 41, and the both ends of described coil are passed from the bending hook portion of two PIN pin respectively and formed one by electric resistance welding and the welding of described bending hook portion.Like this, adopt electric resistance welding that coil is connected on the PIN, can make this tie point unaffected under high temperature impact, can not produce line and be dashed phenomenon.
Preferably, end away from described pcb board of described each PIN pin also is provided with a fixed part 42 that is used for the winding around head, when coil connects, coil head can be wound on this fixed part, thereby can be better the bending hook portion of coil and PIN be connected, can again this fixed part be removed from the PIN pin after the connection.
Claims (2)
1. an alternating current-direct current transforms the electromagnet coil syndeton, comprise coil, this coil is coated its interior coil case (1) and pcb board (2), it is characterized in that: other is provided with a plate (3), and this connecting plate is fixed on the described coil case, and described pcb board is fixed on this connecting plate; Also being respectively equipped with one in the and arranged on left and right sides position of described PCB is electrically connected with PIN pin (4), this each PIN pin has a bending hook portion (41), and the both ends of described coil are passed from the bending hook portion of two PIN pin respectively and formed one by electric resistance welding and the welding of described bending hook portion.
2. alternating current-direct current according to claim 1 transforms the electromagnet coil syndeton, it is characterized in that: the end away from described pcb board of described each PIN pin also is provided with a fixed part (42) that is used for the winding around head.
