In the process of battery case manufacturing, installation, use; Because the external interference of sum of errors, the electric connector of known technology is difficult to guarantee that moving contact and fixed contact relative axial position are constant.
In Chinese patent application 201010196033.X denomination of invention " a kind of electric connector ", showed the elastic linear electric connector of high rigidity, by applying big contact pressure, increased contact microcosmic contact area.Moving contact has used the butterfly spring of high rigidity as the axially mounting element, and when the contact axial location changed, the length of spring compressed stroke changed, and big variation will take place pressure due to the spring, make contact microcosmic contact area change; And then influence instantaneous conductive capability.
The utility model content
In order to address the above problem, the purpose of this utility model provides electric connector a kind of plane contact, that have constant contact pressure, can adapt to the dynamic change of the relative car body of batteries of electric automobile case.
To achieve these goals, electric connector of the present utility model comprises a pair of interconnective contact, and described electric connector comprises a pair of interconnective contact, outer cover, outer cover contact-making surface and spring; Wherein, the interconnective contact-making surface in contact is that the contact is electrically connected contact-making surface, is respectively arranged with outer cover insulation, that be in contact with one another outside the contact; A contact is arranged in the outer cover regularly, and the back of another contact is provided with compressible spring, and the other end of spring is fixed in the outer cover of homonymy; The outer surface of outer cover is the outer cover contact-making surface, in order to form constant length of spring compressed stroke and to guarantee that contact electrical connection contact-making surface contact pressure is constant.
Preferably, be provided with in the described outer cover many to the contact, many to form to being electrically connected.Described contact is made by good copper, copper alloy, aluminium or the aluminium alloy of conduction.
Preferably, described outer cover is made by insulating material.Described outer cover is annular, rectangle, oval shape or round rectangle.
Preferably, described spring is a helical spring.
Preferably, described contact electrical connection contact-making surface is that metal constitutes by the silver system that improves electrical connection properties, gold system, tin at least in part.
Preferably, described electric connector also comprises flexible wire, in order to connect described contact and electric equipment.Described flexible wire is made by multilayer metal foil or strands of metal wire.
The beneficial effects of the utility model are: this electric connector has stable moving contact compression travel, and external interference is stablized, is not subjected to contact force in can keeping using; Keep stable electrical connection properties.It is electrically connected mask stable contact pressure, can keep stable electrical connection properties under the situation of slightly vibration, slightly displacement, can be widely used in the various electric equipment of vibration, displacement operating mode.
Description of drawings
Fig. 1 is the utility model electric connector structure view.
Description of reference numerals is as follows:
Contact 1, outer cover 2, outer cover contact-making surface 3, spring 4, flexible wire 5, nose balance spring 6, contact are electrically connected contact-making surface 7.
Embodiment
In order further to understand structure of the present utility model, feature and other purposes, now be described in detail as follows in conjunction with appended preferred embodiment, illustrated preferred embodiment only is used to technical scheme of the present invention is described, and non-limiting the present invention.
As shown in Figure 1, Fig. 1 Fig. 1 is the utility model electric connector structure view.As seen from Figure 1, pair of contact 1 interconnects, the contact-making surface of described contact is that the contact is electrically connected contact-making surface, a contact 1 is fixedly mounted in one of them outer cover 2, the back of another contact 1 is provided with compressible spring 4, described spring can be helical spring, and in the outer cover that is installed in homonymy 2 that the other end of spring 4 is fixed, outer cover 2 is in contact with one another.The outer surface of outer cover 2 is an outer cover contact-making surface 3, in order to form constant spring 4 compression travels and to guarantee that contact electrical connection contact-making surface 7 contact pressures are constant.
Be provided with in the outer cover 2 many to the contact, many to form to being electrically connected; Contact 1 is made by good copper, copper alloy, aluminium or the aluminium alloy of conduction.Outer cover 2 is made by insulating material, and outer cover 2 is annular, rectangle, oval shape or round rectangle.
The contact-making surface of contact 1 is that the contact is electrically connected contact-making surface 7, and it is that metal constitutes by the silver system that improves electrical connection properties, gold system, tin that the contact is electrically connected contact-making surface 7.Interconnective contact 1 constitutes effectively electrical connection.Outer cover 2 is in contact with one another, and owing to spring 4 is installed in one of them outer cover 2, and is supporting one of them contact 1; The compression travel that contacts rear spring 4 when outer cover 2 no longer changes, thereby the load that imposes on contact 1 also no longer changes, i.e. the pressure that the contact of contact 1 electrical connection contact-making surface 7 is born is constant.
On the outer cover 2 of mounting spring 4, installation shaft is to counterbalance spring 6, the error that counterbalance spring 6 is used for compensating described electric connector fixed support, installing component and contact 1 and outer cover 2 is made, produce in the installation process, and the contingent axial displacement of electric connector described in the use.The rigidity of described counterbalance spring 6 is greater than spring 4, thereby guaranteed described electric connector when a spot of axial displacement takes place, and outer cover 2 contacts all the time, and it is constant to keep the compression travel of spring 4.
