Abstract
The utility model relates to a low-impedance battery connector terminal, which comprises a basal part, a welding part, a first extended part, a second extended part, a first bended part, a second bended part and an elastic contact arm, wherein the welding part is formed by extending from one end of the basal part; the first extended part is formed by being vertically bended and extending from the other end of the basal part; the second extended part is formed by being reversely bended and extending from the tail end of the first extended part; the first bended part is formed between the first extended part and the second extended part; the second bended part is formed by being upwardly bended from the tail end of the second extended part; the elastic contact arm is formed by upwardly extending from the tail end of the second bended part; two sides of the basal part extend towards the second bended part to form two contact sheets; and the contact sheets are electrically connected to the second bended part when the elastic contact arm is in the compression state. The low-impedance battery connector terminal disclosed by the utility model is low in impedance and is suitable for high current to pass through.
Description
Technical field
The utility model relates to battery connector, espespecially a kind of battery connector Low ESR terminal.
Background technology
The dimensional requirement of battery connector for mobile phone is more and more less, and the electric current that requirement is passed through is increasing, and traditional battery connector is the elastic buckling dynamics that guarantees terminal with terminal, terminal repeatedly can be bent form some elastic portion to guarantee the elasticity of terminal, and such length of terminal that also can lengthen undoubtedly, increase the flow through distance of terminal of electric current, be unfavorable for passing through of large electric current; Although adopting low resistivity materials is a kind of selection, low resistivity materials is more expensive, and can not meet the market demand growing to current delivery.
Utility model content
The purpose of this utility model is to provide a kind of Low ESR terminal of cell connector.
For this reason, the utility model provides a kind of Low ESR terminal of cell connector, comprise base portion, the weld part extending to form from base portion one end, the first extension extending to form from the vertical bending of the base portion other end, the second extension extending to form from the first extension end inverse bending, be formed at the first fold turn of bilge between the first extension and the second extension, from the second extension end the second bending part that bending forms that makes progress, and from the second bending part end, extend upward the elastic contact arm of formation, the both sides of described base portion have extended to form two contact chips towards described the second bending part direction, described contact chip is described the second bending part in electrical contact when described elastic contact arm is under compressive state.
On described the second bending part, be formed with pars convoluta, described pars convoluta is positioned at the position of the most close described the second bending part of in the vertical direction.
Described contact chip is in electrical contact with described the second bending part by contacting described pars convoluta.
After the bending downwards of described elastic contact arm end, inwardly bending is formed with pre-splenium again.
Described base portion both sides are provided with some hangnails.
With respect to prior art, the utility model by Low ESR terminal of cell connector by extend the contact chip that contacts the second bending part in work under compressive state in base portion both sides, the transmission path that makes electric current reduces impedance greatly because of in parallel.
Accompanying drawing explanation

Fig. 2 is the end view of the utility model Low ESR terminal of cell connector.
Fig. 3 is the utility model Low ESR terminal of cell connector working state figure.
Embodiment
Refer to shown in Fig. 1 to Fig. 3, the utility model Low ESR terminal of cell connector comprises base portion 10, the weld part 11 extending to form from base portion 10 one end, the first extension 12 extending to form from the vertical bending of base portion 10 other end, the second extension 14 extending to form from the first extension 12 end inverse bendings, be formed at first fold turn of bilge 13, the second bending part 15 forming from the second extension 14 ends bending vertically upward between the first extension 12 and the second extension 14 and from the second bending part 15 ends, extend upward the elastic contact arm 16 of formation.On described the second bending part 15, be formed with pars convoluta 151, described pars convoluta 151 is positioned at the position of the most close described the second bending part 15 of in the vertical direction.
The both sides of described base portion 10 have extended to form two contact chips 18 towards described the second bending part 15 directions, described contact chip 18 terminal in work during compressive state and the pars convoluta 151 of described the second bending part 15 in electrical contact, so, between the first extension 12, first fold turn of bilge 13, the second extension 14 and contact chip 18, form relation in parallel, greatly reduce transfer impedance, be more conducive to passing through of large electric current.
After the bending downwards of described elastic contact arm 16 ends, inwardly bending is formed with pre-splenium 17 again.Described base portion 10 both sides are provided with some hangnails 19.
Compared to prior art, the utility model Low ESR terminal of cell connector is by extending the contact chip that contacts the second bending part 15 in work under compressive state in base portion 10 both sides, and the transmission path that makes electric current reduces impedance greatly because of in parallel.
