Abstract
The present invention relates to a contact spring and a connector having the same that the voltage drop or the amount of heat generated in the contact member of the connector for an electric vehicle can be minimized.
Description
The present invention relates to a contact spring applied to a connector for an electric vehicle and a connector having the same. More specifically, the present invention relates to a contact spring and a connector having the same that the voltage drop or the amount of heat generated in the contact member of the connector for an electric vehicle can be minimized.
Conventional cars using only fossil fuels seriously cause environmental problems or fuel depletion problems, and thus automobiles are being used that can reduce these problems.
Hybrid vehicles using fuel and batteries and electric vehicles using only charged electrical energy are used or introduced. Both hybrid and pure electric vehicles can be classified into a wide range of electric vehicles in that they are used as a power source for driving power by charging electric energy.
Such an electric vehicle may include a motor and a rechargeable battery, and the rechargeable battery may be charged from a high voltage power source, or the like, and may drive electric motors charged in the rechargeable battery to drive a motor. Unlike electric cars, electric vehicles require high voltages of hundreds of volts and high currents of tens to hundreds of amperes, and thus, connectors and cables connecting rechargeable batteries, inverters, and motors are used for electric vehicles. .
In order to interconnect the two cables, the terminals are mounted on each of the two cables, and each terminal can be electrically connected by connecting the terminals.
One of the two terminals to be connected is a male terminal, and the other may have the form of a female terminal into which the male terminal can be inserted.
In addition, since the connector for an electric vehicle is exposed to continuous vibration or shock, a contact spring may be employed inside the male terminal and the female terminal to ensure reliability of the electrical connection state.
In the case of the contact springs for connectors, the main focus was on increasing the contact area between the terminals and the contact springs and enhancing the mechanical stability.However, when hundreds of amperes of current flow, heat generation becomes severe in the contact springs. have.
An object of the present invention is to provide a contact spring and a connector having the same, which can minimize voltage drop or heat generation amount in a contact member of an electric vehicle connector.
In order to solve the above problems, the present invention is a female type having a female terminal portion to which the first cable is connected, a male terminal having a bar-shaped male terminal portion and a second cable are connected, and a male terminal portion of the male connector is inserted. A contact spring mounted between the terminals, each of which has protrusions on opposite sides to electrically connect the outer surface of the male terminal portion of the male terminal and the inner surface of the terminal portion of the female terminal in a direction perpendicular to the longitudinal direction of the male terminal portion. It provides a contact spring connected in the form of a ring including a plurality of contact members in the form of a long plate and a connecting portion for connecting at least two points to the side provided with the protruding portion of the adjacent contact member.
In addition, two adjacent contact members constituting the contact spring may be connected in an inclined state so as not to be parallel or coplanar in an inclined state in a predetermined direction.
In addition, the side surface of the contact member is formed with the protrusion and the connection portion may be a long side.
Here, the pair of protrusions of the contact member may be formed at a corresponding position on the parallel long side surface of the contact member.
In this case, the pair of connecting portions provided in the contact member may be bent at a predetermined angle smaller than 90 degrees in the opposite direction.
In addition, the pair of protrusions provided on the contact member may be bent a predetermined angle of less than 90 degrees in the opposite direction.
In addition, the connection portion and the protrusion provided on the same side of the contact member is bent in the same direction, the bending angle of the connection portion may be greater than the bending angle of the protrusion.
In addition, each of the protrusions of the contact member may have opening holes open to a predetermined area.
Here, the opening hole may be formed in the bent portion of the protrusion of the contact member.
In this case, the support may protrude from one of the two side surfaces at which the protrusions of the contact member are formed.
In addition, two support parts may be provided outside the connection part.
In addition, the pair of protrusions provided on the contact member may be bent at a predetermined angle smaller than 90 degrees in the opposite direction, and the support portion may have a form bent in the same direction as the bending direction of the protrusion formed on the contact member.
The support portion may be formed on one side of the long side of the contact member such that the male terminal contacts the male terminal portion.
Here, the contact spring may be manufactured by punching, bending and joining a metal plate.
In addition, in order to solve the above problems, the present invention includes a male terminal portion to which the first cable is connected, a male terminal having a bar-shaped male terminal portion, a second cable is connected, and a male terminal portion of the male connector is inserted. The female terminal and a connector including the above-described contact spring can be provided.
In this case, a mounting groove in which the contact spring can be secured may be provided on an inner side surface of the female terminal portion of the female terminal.
In addition, the male terminal and the female terminal may be terminals for driving power of an electric vehicle.
When the contact spring and the connector having the same according to the present invention are mounted to a connector including a power terminal of an electric vehicle, voltage drop or heat generation can be minimized even when a high current is applied.
In addition, the contact spring and the connector having the same according to the present invention can improve the reliability of the electrical connection state of the power terminal of the electric vehicle.
