Abstract
The utility model discloses an electromagnetic wire coil comprising an electromagnetic wire coil main body, a leading wire, and a wiring terminal, wherein the wiring terminal comprises a fastening ring piece; the fastening ring piece of the wiring terminal fastens and wraps the leading wire in a cold pressing way; and the leading wire is in spot welding connection with the wiring terminal. The fastening method of the wiring terminal and the leading wire adopts a spot welding and cold pressing technology, therefore, the electromagnetic wire coil overcomes the technical bias, solves the long-term technical problem in the field, enables the leading wire to be reliably electrically connected with the wiring terminal, and does not generate dry joint; and meanwhile, wicking links is cancelled in the production process, and the electromagnetic wire coil does not use lead and tin which contain toxic substances, thereby conforming to international environmental protection requirements.
Description
Technical field
The utility model relates to the electromagentic furnace technology field, particularly a kind of electromagnetism drum.
Background technology
At present in the electromagnetic oven industry, the fastening means of electromagnetism drum lead and binding post is to adopt the mode of the back wicking of colding pressing, promptly earlier stranded the colding pressing of stranded conductor is anchored on a binding post, and then lead-tin soldering is carried out in twisted conductor and binding post junction, to guarantee fully contacting of stranded conductor and binding post, satisfy the stress requirement of contact point simultaneously.But in the prior art owing to be to use lead-tin soldering, and have to a certain degree distortion during solder cools, can cause loose contact between lead and the binding post, the situation that also may have rosin joint, in use, damage because of this problem causes electromagnetic oven easily, and this kind fastening means does not meet the requirement of national electronic product safety.Need use slicker solder when welding in addition, and contain this harmful material of lead (Pb) in the slicker solder, the requirement that this does not meet European Union's " using some harmful substance instruction about restriction in electronic electric equipment " (being the RoHs instruction) does not yet meet environmental regulations.But, for a long time, the electromagnetic oven industry does not have technological break-through on the fastening means of electromagnetism drum lead and binding post, prolongs the above-mentioned technology of using always, cause the electromagnetism drum lead and the binding post electric connection of electromagnetic oven unreliable, and do not meet safety requirement and environmental regulations.
The utility model content
The purpose of this utility model is to provide that a kind of binding post contacts with lead well, the electromagnetism drum of compliance with environmental protection requirements, to overcome weak point of the prior art.
To achieve these goals, the utility model electromagnetism drum is reached by the following technical programs:
A kind of electromagnetism drum includes electromagnetic wire disc main body, lead and binding post, and described binding post includes fastening ring plate, and spot welding is connected between the fastening ring plate of the described binding post described lead of fastening parcel of colding pressing, described lead and binding post.
Compared to prior art, the utility model electromagnetism drum is because its binding post and lead fastening method use spot welding, the technology of colding pressing, overcome technology prejudice, solved this area technical barrier for a long time, lead and binding post are reliably electrically connected, can not produce rosin joint; Simultaneously cancel the wicking link in process of production, do not use the slicker solder that contains Toxic matter, meet international environmental requirement.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model embodiment electromagnetism drum connection diagram.
Fig. 2 is drum lead and a binding post junction enlarged drawing among the utility model embodiment Fig. 1.
Fig. 3 is the fastening back of a drum lead and binding post junction enlarged drawing among the utility model embodiment Fig. 1.
Embodiment
Further specify the technical solution of the utility model below in conjunction with drawings and Examples.
As shown in Figure 1, be the utility model embodiment electromagnetism drum schematic diagram.The electromagnetism drum of the utility model embodiment comprises drum main body 1, lead 2 and binding post 3, and lead 2 is installed on the drum main body 1, and the two ends of lead 2 pick out from drum main body 1, and lead 2 two ends are connected with two binding posts 3 respectively.
As Fig. 2, shown in Figure 3, be drum lead among the utility model embodiment Fig. 1 and binding post junction 23 enlarged diagrams.During being connected of lead 2 and binding post 3, earlier with between stranded two the fastening ring plates 32 that place binding post 3 of lead 2; Line end with lead 2 is connected through spot welding with binding post 3 again, forms spot welding point 31; At last two fastening ring plates 32 processes of binding post 3 are colded pressing, lead 2 is anchored in the ring plate.
The utility model electromagnetism drum has overcome technology prejudice, has solved this area technical barrier for a long time because its binding post and lead fastening method use spot welding, the technology of colding pressing, and lead and binding post are reliably electrically connected, and can not produce rosin joint; Simultaneously cancel the wicking link in process of production, do not use the slicker solder that contains Toxic matter, meet international environmental requirement.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not with opposing qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
Claims (2)
1, a kind of electromagnetism drum, include electromagnetic wire disc main body, lead and binding post, described binding post includes fastening ring plate, the fastening ring plate of the described binding post described lead of fastening parcel of colding pressing, it is characterized in that spot welding is connected between described lead and the binding post.
2, electromagnetism drum according to claim 1 is characterized in that, first spot welding is connected between described lead and the binding post, and then by the described fastening ring plate described lead of fastening parcel of colding pressing.
