Abstract
The utility model discloses a big current switch contact rivet possessing multiple contacts. The big current switch contact rivet includes a cylindrical rivet tail and an integrated cylindrical rivet head. The rivet tail and the rivet head are made of pure copper. The rivet tail and the rivet head are coaxially connected, and the cross section is T-shaped. The upper surface of the rivet head is provided with a contact part which is made of hard high strength composite silver. The upper surface of the contact part is provided with multiple tapered contacts which electrically contact with other electrical elements. The big current contact rivet is dust-proof, and can reduce the noise and prolong the service lifetime of a switch.
Description
Technical field
The utility model relates to the high-current switch contact that automobile is used, and especially refers to have the high-current switch contact rivet of a plurality of contacts.
Background technology
See also Fig. 1, automobile-used conventional high-current switch contact rivet 1 comprises the columned ailhead 12 of columned nail tail 11 and one in the prior art, and nail tail 11 and ailhead 12 are processed by fine copper, and both are coaxial to link to each other and the cross section is the T font.At ailhead 12 upper surfaces is that the contact site 13 of one deck fine silver material is used to contact other electric component conducting electric currents.But this kind is designed with following shortcoming.
1. if this high-current switch contact rivet 1 uses to be connected with motor in the window direction switch and directly, switch breaks off or conducting moment all can produce electric arc when motor rotation blockage, to the contact site 13 surface generation ablations of rivet, minimizing switch lifes.
2. contact site 13 surfaces of rivet 1 also can cause switch loose contact or disabler if dust is arranged.
3. contact site bump sound is louder when switch conduction, produces unnecessary noise.
The utility model content
The purpose of the utility model is to provide a kind of high-current switch contact rivet with a plurality of contacts, and it can realize prolonging switch life, reduces the probability of switch failure in the environment of many dusts, and the noise that produces can reduce switching manipulation the time.
To achieve these goals, the utility model provides following technical scheme.
A kind of high-current switch contact rivet with a plurality of contacts, comprise a nail tail and with the ailhead of nail tail one, be a contact site at the ailhead upper surface, the upper surface of contact site is provided with a plurality of bump contact and is used to contact other electric component conducting electric currents.
Further, contact site and on bump contact be the compound silver-colored material of high strength.
Further, said bump contact is taper or truncated cone-shaped.
Further, nail tail and ailhead all are cylindric, and both are the T font in coaxial continuous and cross section.
Further, nail tail and ailhead are to be processed by fine copper.
The technical scheme of the utility model is compared with existing design; On the contact site of the ailhead of high-current switch contact rivet, a plurality of bump contact are set; So just change original contact site into to bore some contact by plane or cambered surface more; Slider material changes the compound silver of harder high strength into by softer fine silver, and technological beneficial effect explanation as follows.
1. if use and in the window direction switch, directly to be connected with motor, switch disconnection or conducting moment all can produce electric arc when motor rotation blockage.Because the contact site surface is the multiple spot conducting, and is the compound ag material of high strength, can weaken contact site and ablate the influence of switch life, prolong switch life greatly.
2. even there is dust on the contact site surface, because the contact site surface is multiple spot contact and can not cause switch loose contact or disabler.
When switch conduction since the contact area of the taper contact on contact site surface less than original plane or cambered surface contact, so conducting bump sound is less, less noise.
Description of drawings
Fig. 1 is the stereogram of high-current switch contact rivet in the prior art.
Fig. 2 is the stereogram that the utlity model has the high-current switch contact rivet of a plurality of contacts.
Embodiment
Specify the embodiment of the utility model below in conjunction with accompanying drawing.
See also Fig. 2, the high-current switch contact rivet 2 that the utlity model has a plurality of contacts comprises the columned ailhead 22 of columned nail tail 21 and one, and nail tail 21 and ailhead 22 are processed by fine copper, and both are coaxial to link to each other and the cross section is the T font.At ailhead 22 upper surfaces is the contact site 23 of the harder compound silver-colored material of high strength of one deck, and the upper surface of contact site 23 is provided with a plurality of bump contact 24 and is used to contact other electric component conducting electric currents.In one embodiment, these bump contact 24 are set to taper, are appreciated that these bump contact 24 also can be provided with to be truncated cone-shaped or cylindrical.
Owing to be provided with these bump contact 24; Make rivet 2 contact sites 23 in contact change into and comprise a plurality of tapers or truncated cone-shaped or columniform contact by original plane or cambered surface; Slider material changes the compound silver of harder high strength into by softer fine silver, thereby obtains following useful technique effect.
1. if use and in the window direction switch, directly to be connected with motor, switch disconnection or conducting moment all can produce electric arc when motor rotation blockage.Because the contact site surface is the multiple spot conducting, and is the compound ag material of high strength, can weaken contact site and ablate the influence of switch life, prolong switch life greatly.
2. even there is dust on the contact site surface, because the contact site surface is multiple spot contact and can not cause switch loose contact or disabler.
When switch conduction since the contact area of the taper contact on contact site surface less than original plane or cambered surface contact, so conducting bump sound is less, less noise.
Understand easily, according to the technical scheme of the utility model, under the connotation that does not change the utility model, but one of ordinary skill in the art can propose the multiple frame mode and the implementation of mutual alternative.Therefore, following embodiment and accompanying drawing only are the exemplary illustrations to the technical scheme of the utility model, and should not be regarded as the whole of the utility model or be regarded as qualification or the restriction to the utility model technical scheme.
