Abstract
The invention relates to the field of electrical connectors, in particular to a contact spring and a brush contact element applying the same. The contact spring comprises a mother ring, at least one cantilever-type elastic contact finger is arranged on the inner side of the mother ring, each elastic contract finger comprises a fixing end located on the mother ring and a contact end gradually drawing close to the center line of the mother ring, and the contact end gradually shifts to one side of the mother ring and protrudes out of the corresponding side face of the mother ring during the process of drawing close to the center line of the mother ring. During use, the contact spring can be pressed on corresponding electric slip rings in a contact mode through the elastic contact fingers; a filamentous brush contact element in the prior art is abandoned, so that requirements on transmission power of the brush contact element can be met by means of adjusting thickness, diameter and the like of the contact spring; due to change in contact structure, the elastic contact fingers can be matched with the electric slip rings larger and thicker in size, so that the transmission power of the electrical connectors can be improved on the premise of not increasing the axial size of the electrical connectors.
Description
Technical field
The present invention relates to electric connector field, particularly relate to a kind of contact spring and use the contact element of electric brush of this contact spring.
Background technology
Contact element of electric brush and electric slip ring are two core components in rotary electric connector, contact element of electric brush is fixed on the housing of electric connector often, electric slip ring is then be fixed on a rotating shaft, when rotating shaft rotates about the axis, contact element of electric brush coordinates the interrupted transmission that can realize the signal of telecommunication with electric slip ring.The current contact element of electric brush overwhelming majority is thread, it is splayed and is clipped on corresponding electric slip ring, it is brush that it mainly contains compound brush block formula, noble metal monofilament formula and fiber, such as application number is 201010227485,2010202597743,201020597669,201020259764X, 2010202597739,2010202429625, just individually disclose the technology relevant with said structure in the Chinese patent of 2010202597654 and 2010206154918.
Above-mentioned contact element of electric brush and electric slip ring obtain and apply very widely in rotary electric connector, but when running into the occasion adopting electric slip ring transmission high-power (electric current is greater than 200A), due to the single contact element of electric brush of said structure and the power limited of electric slip ring, therefore need to adopt multi-channel parallel to carry out common transport power, but, owing to being subject to machine work, the impact of the factors such as assembling, the actual power of every bar transmission route is not identical, in such cases, when to contact element of electric brush and electric slip ring design power amount of redundancy less time, then because actual transmission power difference may cause indivedual path to burn out, thus cause the inefficacy of whole electric connector, when power designs amount of redundancy is larger, then need the axial dimension increasing electric connector accordingly, thus, just can waste a large amount of materials, the cost of product also can rise thereupon.
Summary of the invention
The object of the present invention is to provide a kind of contact spring transmitting high-power electric current, to improve its through-put power under the prerequisite of axial dimension not increasing rotary electric connector.
Meanwhile, the present invention also aims to provide the contact element of electric brush using above-mentioned contact spring.
In order to solve the problem, contact spring is by the following technical solutions: contact spring, comprise female ring, the inner side of described female ring is provided with at least one cantilevered elasticity fingertip, elasticity fingertip comprises and is positioned at stiff end in female ring and gradually to the contact jaw that the center line of female ring is drawn close, described contact jaw in the process of drawing close to female ring center line gradually to female ring side skew and protrude from the respective side of female ring.
Described elasticity fingertip has two or more and center line around female ring is evenly arranged.
Described elasticity fingertip reduces from its stiff end gradually to contact jaw.
Elasticity fingertip is trapezoidal fingertip.
Contact element of electric brush is by the following technical solutions: contact element of electric brush, comprise conducting ring, the at least side of conducting ring is pasted with contact spring, described contact spring comprises female ring, the inner side of described female ring is provided with at least one cantilevered elasticity fingertip, elasticity fingertip comprises and is positioned at stiff end in female ring and gradually to the contact jaw that the center line of female ring is drawn close, described contact jaw stretches to gradually in the endoporus of conducting ring in the process of drawing close to female ring center line.
The elasticity fingertip of each contact spring has two or more and center line around its female ring is evenly arranged.
Described elasticity fingertip reduces from its stiff end gradually to contact jaw.
Elasticity fingertip is trapezoidal fingertip.
The both sides of conducting ring are all pasted with described contact spring.
Because this contact spring comprises female ring, and the inner side of female ring is provided with at least one cantilevered elasticity fingertip, elasticity fingertip comprises and is positioned at stiff end in female ring and gradually to the contact jaw that the center line of female ring is drawn close, the side of contact jaw gradually to female ring in the process of drawing close to female ring center line of female ring offsets and protrudes from the respective side of female ring, therefore, when in use, this contact spring can touch on corresponding electric slip ring by its elasticity fingertip pressure, owing to having abandoned thread contact element of electric brush of the prior art, therefore can by the thickness of adjustment contact spring, the modes such as diameter make it possess the through-put power of requirement, the change due to contact structures equally, elasticity fingertip can be larger with volume, thicker electric slip ring coordinates, thus its through-put power can be improved under the prerequisite of axial dimension not increasing rotary electric connector.
Further, multiple elasticity fingertip contributes to increasing the contact area between contact spring and corresponding electric slip ring, thus increases the power of contact spring further; Make elasticity fingertip from its stiff end to the reasonable layout contributing to its elastic force after contact jaw reduces gradually, make elasticity fingertip stress concentration portion position operationally more solid and reliable; After elasticity fingertip is set to trapezoidal fingertip, the convenient processing to contact spring, specifically, because female ring is annular, therefore its diameter necessarily reduces from outside to inside gradually, if when at this time making elasticity fingertip by the mode of stamping-out, elasticity fingertip is set to trapezoidal obviously can one-shot forming and can material be made full use of.
