Abstract
The utility model relates to a binding post for a coil. The binding post is used for being electrically connected with leads of the coil, and comprises pins and wiring parts used for being connected with the leads of the coil, wherein the wiring parts and the pins are integrally molded. By the binding post, by adoption of the integrated molding structure of the pins and the wiring parts, full and good contact is kept between the pins and the wiring parts after the leads are fixedly connected with the wiring parts, and the contact resistance is eliminated, so that the output current at the pins is stable; and therefore, the electrical property stability of the binding post and the coil is improved, and the potential safety hazard caused by heating due to extremely high contact resistance is eliminated.
Description
Technical field
The utility model relates to technical field of electronic components, particularly a kind of coil and binding post thereof.
Background technology
Coil is widely used as transformer, rotor and electromagnetic induction element etc., generally comprises coil body, winding and binding post etc.Coil body generally all comprises wrapping post and is arranged at the back-up ring that the wrapping post two ends are used for the stop lacquers envelope curve that enamelled wire is wrapped on the wrapping post, and draws the lead-in wire of positive and negative electrode, is used for being connected with binding post.
The binding post of existing coil generally includes pin and sheathed and be fixed in the wire connecting portion on the pin; Lead-in wire on the coil then is fixed on the above-mentioned wire connecting portion with welding or riveted way; Electric current flows on the wire connecting portion through lead-in wire, imports on the pin through wire connecting portion again, inputs or outputs through pin again.
The binding post of said structure owing to adopt the formula of pressing to be fixedly connected mode between pin and the wire connecting portion usually, makes to have certain contact resistance between pin and the wire connecting portion; And contact area is less, causes contact resistance excessive, even constantly changes; Cause coil in use; The unsettled phenomenon of loose contact or electric current usually can occur, bring very big inconvenience, even cause security incident to the user.
The utility model content
The main purpose of the utility model is, to above-mentioned deficiency of the prior art, a kind of coil and binding post thereof is provided, with problems such as the loose contact that usually can occur in the above-mentioned solution prior art or electric current instabilities.
For realizing the foregoing invention purpose, the utility model adopts following technical scheme.
The binding post that the utility model provides a kind of coil to use is used for electrically connecting with the lead-in wire of coil, comprises pin and the wire connecting portion that is used for being connected with the lead-in wire of coil, and said wire connecting portion and said pin are one-body molded.
Preferably, said wire connecting portion comprises body and intermediate plate, forms clamp body between said body and the intermediate plate.
The utility model also provides a kind of coil, and it comprises coil body and binding post, and said coil body comprises back-up ring, and said binding post is fixed on the said back-up ring, and said binding post is above-described binding post.
Than above-mentioned prior art, the utlity model has following advantage.
The binding post of the utility model adopts pin and wire connecting portion integrate shaped type structure; After making lead-in wire and wire connecting portion being fixedly connected; Keep between pin and the wire connecting portion fully and excellent contact, eliminated contact resistance, make the outputting current steadily at pin place; Thereby improved the electric performance stablity property of binding post and coil, also eliminated the potential safety hazard of generating heat and causing because of contact resistance is excessive.
Description of drawings

The realization of the utility model purpose, functional characteristics and advantage will combine embodiment, further specify with reference to accompanying drawing.
Embodiment
Below will combine accompanying drawing and specific embodiment to specify the technical scheme of the utility model, so as clearer, understand the invention essence of the utility model intuitively.
Fig. 1 is the structural representation of the utility model embodiment middle connecting terminal.
With reference to shown in Figure 1; Present embodiment provides a kind of binding post 100, and this binding post 100 is used for electrically connecting with the positive and negative electrode lead-in wire 400 of coil, comprises pin 110 and wire connecting portion 120; Wherein, Wire connecting portion 120 is used for being connected with the lead-in wire 400 of above-mentioned coil, and, wire connecting portion 120 and pin 110 structure that is formed in one.
Particularly; Wire connecting portion 120 comprises body 121 and intermediate plate 122, and body 121 is connected with pin 110, and intermediate plate 122 forms clamp body with body 121; Can lead-in wire 400 be put into; Utilize instrument such as pliers that intermediate plate 122 and body 121 are pressed then, perhaps will go between 400 is welded between intermediate plate 122 and the body 121,400 is fixed on tightly on the wire connecting portion 120 thereby will go between.
The binding post 100 of present embodiment adopts structure like this, not only can make being connected between lead-in wire 400 and the binding post 100 become more convenient, and make between lead-in wire and wire connecting portion 120, wire connecting portion 120 and the pin 110 electric connection more reliably and stablize.Avoided variety of issue because of loose contact or heating generation.
Fig. 2 is the structural representation of coil among the utility model embodiment.
With reference to shown in Figure 2; The utility model embodiment provides a kind of coil 200, and it comprises coil body 210 and binding post 300, and coil body 210 comprises back-up ring 211; This back-up ring 211 is provided with installing handle 212, and above-mentioned binding post 300 promptly is mounted on the installing handle 212.Also be provided with winding 220 on the coil 200, this winding 220 is drawn two lead-in wires 230,240 of positive and negative electrode certainly, and these two lead-in wires 230,240 are connected with above-mentioned binding post 300 respectively, form the positive and negative electrode binding post of coil 200.The binding post 300 of present embodiment can adopt binding post embodiment illustrated in fig. 1, and lead-in wire 230,240 is wrapped in earlier on the installing handle 212 after winding 220 is drawn, again with binding post 300 welding or riveted and fixed.
Present embodiment adopts structure like this, has avoided the loose contact and the excessive phenomenons such as heating that cause of contact resistance of binding post 300, makes coil 200 have better electric stability and reliability.
In sum; The binding post of the utility model adopts pin and wire connecting portion integrate shaped type structure, after making lead-in wire and wire connecting portion being fixedly connected, keeps between pin and the wire connecting portion fully and excellent contact; Eliminated contact resistance; Make the outputting current steadily at pin place, thereby improved the electric performance stablity property of binding post and coil, also eliminated the potential safety hazard of generating heat and causing because of contact resistance is excessive.
