Abstract
The utility model discloses a wafer for a plum blossom contact. The upper part of the inner side of the wafer is provided with a contact part capable of being in contact with a static contact, the contact part is in an arc shape, and the circular arc radius of the contact part is greater than or equal to 6mm but is smaller than or equal to 15mm.The circular arc radius of the contact part is greater than or equal to 6mm but is smaller than or equal to 15mm, the contact area of the wafer and the static contact is increased, the current conduction quantity is increased, and the heating problem of a contact point of the contact is solved. In addition, the thickness of the wafer can be changed into 2 to 2.5mm through accounting the cross section area of the conduction current, the weight of the wafer is reduced, the materials are saved, and the manufacture cost is reduced.
Description
Technical field
The utility model relates to a kind of Mume flower contact contact.
Background technology
Mume flower contact is one of normal parts that use in the middle piezoelectricity device, and in middle piezoelectricity device, Mume flower contact is to be used to realize that as the conduction parts that are slidingly connected the conduction between contact arm and the fixed contact connects.The Mume flower contact of prior art includes contact, plum blossom sheet, first extension spring, second extension spring, and the plum blossom sheet is an annular, and some contacts are assemblied in looping body on the plum blossom sheet.The bottom of the inboard of this contact is provided with and can meets and discusses with contact arm contacted first, and the top of the inboard of this contact is provided with and can meets and discusses with fixed contact contacted second.The bottom in the outside of this contact is provided with and is used for inwardly binding this and first meets and discusses and this contact arm is realized that first extension spring that well contact, the top in the outside of this contact are provided with and is used for inwardly binding this and second meets and discusses and this fixed contact is realized good second extension spring that contacts.
But, second of contact of the prior art meet and discuss and fixed contact between contact area little, influenced the conducting amount of electric current, be unfavorable for the temperature rise test and the moving heat test of circuit breaker.
The utility model content
The utility model provides a kind of Mume flower contact contact, and it has overcome the existing deficiency of background technology.The technical scheme that its technical problem that solves the utility model adopts is:
A kind of Mume flower contact contact, the top of this contact inboard be provided with can with the contacted contacting part of fixed contact, the curved shape of this contacting part, the arc radius of this contacting part more than or equal to 6mm smaller or equal to 15mm.
Among one preferred embodiment: the arc radius value of this contacting part more than or equal to 8mm smaller or equal to 12mm.
Among one preferred embodiment: the arc radius value of this contacting part more than or equal to 9.5mm smaller or equal to 11mm.
Among one preferred embodiment: the one-tenth-value thickness 1/10 of this contact more than or equal to 1.8mm smaller or equal to 2.8mm.
Among one preferred embodiment: the one-tenth-value thickness 1/10 of this contact is 2mm or 2.5mm.
Among one preferred embodiment: the weight of this contact restrains smaller or equal to 18 more than or equal to 10 grams.
Among one preferred embodiment: the weight of this contact is 13 grams.
Among one preferred embodiment: the middle part of this contact inboard is provided with groove.
Among one preferred embodiment: this contact is to be stamped to form by copper plate.
The technical program is compared with background technology, and it has following advantage:
1. the arc radius of this contacting part smaller or equal to 15mm, has increased the contact area of this contact and fixed contact more than or equal to 6mm, has strengthened conductive current, has overcome the heating problem of contact, is very beneficial for the temperature rise test and the moving heat test of circuit breaker.
2. the one-tenth-value thickness 1/10 of this contact smaller or equal to 2.8mm, alleviates the weight of this contact more than or equal to 1.8mm, saves material, reduces manufacturing cost.
3. the middle part of this contact inboard is provided with groove, has further alleviated the weight of this contact, further reaches the effect of saving material.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 has illustrated the schematic perspective view of the Mume flower contact made from contact of the present utility model.
The master that Fig. 2 has illustrated Mume flower contact shown in Figure 1 looks schematic diagram.
The master that Fig. 3 has illustrated the contact of Mume flower contact shown in Figure 1 looks schematic diagram.
Embodiment
Please refer to Fig. 1 and Fig. 2, Mume flower contact 100 is to be assemblied in looping body on the plum blossom sheet 20 by several contacts 10 of the present utility model.
Please refer to Fig. 3, this contact 10 is to be stamped to form by copper plate.The one-tenth-value thickness 1/10 of this contact 10 more than or equal to 1.8mm smaller or equal to 2.8mm.Preferably, the one-tenth-value thickness 1/10 of this contact 10 is 2mm or 2.5mm.The weight of this contact 10 restrains smaller or equal to 18 more than or equal to 10 grams.Preferably, the weight of this contact 10 is 13 grams.
The bottom of these contact 10 inboards is provided with and can meets and discusses 11 with contact arm is contacted.The top of these contact 10 inboards be provided with can with the contacted contacting part 12 of fixed contact.The middle part of these contact 10 inboards is provided with a groove 13.This groove 13 is met and discussed between 11 between this contacting part 12 and this.
These contacting part 12 curved shapes, the arc radius R of this contacting part 12 more than or equal to 6mm smaller or equal to 15mm.Preferably, the arc radius R of this contacting part 12 more than or equal to 8mm smaller or equal to 12mm.More preferably, the arc radius R of this contacting part 12 more than or equal to 9.5mm smaller or equal to 11mm.
