It may include a contact spring 200 to which the plurality of contact members 210 to be elastically supported at the same time as the electrical connection in the direction perpendicular to the longitudinal direction of the terminal portion 310 is connected in the form of a ring.

The connector 1 according to the invention can be used to interconnect a power delivery cable or component for an electric vehicle. That is, the male terminal and the female terminal constituting the connector 1 according to the present invention may be a terminal for driving power of an electric vehicle.

The connector 1 according to the present invention is a configuration for connecting a pair of electric vehicle cables.

The male terminal 300 to which the first cable is connected may include a male terminal portion 310 having a bar shape having a circular cross section, and a cable connection portion 320 may be provided behind the male terminal portion 310. .

The front end 312 of the male terminal part 310 of the male terminal 300 may be rounded, and correspondingly, the inlet end 112 of the female terminal part 110 of the female terminal 100 may also be easily inserted. It may have a tapered shape to make it.

The cable connection part 320 of the male terminal 300 may be configured in the form of a cable insertion hole into which a cable can be inserted.

The female terminal 100 may include a female terminal part 110 having a pipe shape so that the male terminal part 310 of the male terminal 300 may be inserted. Therefore, the male terminal part 310 of the male terminal 300 may be inserted into the insertion hole 111 inside the female terminal part 110 of the female terminal 100.

A rear side of the female terminal unit 110 may be provided with a cable connection unit 120 for a cable connection, the cable connection unit 120 may be provided with a connection hole (122).

Both the cable connection part 320 of the male terminal 300 and the cable connection part 120 of the female terminal 100 may be formed in the shape of an insertion hole or a connection hole, or may be configured opposite to the shape shown in FIG. 1.

In the case of an electric vehicle, since vibration or shock is continuously transmitted to the connector 1 side when the vehicle is driven, reliability of a contact state must be secured unlike a general electrical connector 1.

Therefore, the connector 1 according to the present invention electrically supports an outer surface of the male terminal portion 310 of the male terminal 300 and an inner surface of the female terminal portion 110 of the female terminal 100 and at the same time elastically supports it. It may include a contact spring (200).

Specifically, the contact spring 200 is provided so as to be in contact in a pressed state so that the terminal portion of each terminal can be firmly electrically contacted in the fastening state of the male terminal 300 and the female terminal 100. do.

The contact spring 200 may include a plurality of contact members 210 which are electrically connected to each other in a direction perpendicular to the longitudinal direction of the male terminal part 310 and are elastically supported. It may be circularly connected to have a ring shape.

2, a contact spring 200 of the connector 1 according to the present invention will be described.

2 shows a contact spring 200 according to the invention.

The contact spring 200 according to the present invention is a female type having a female terminal portion to which a first cable is connected, a male terminal having a male terminal portion in the form of a bar, and a second cable are connected, and a male terminal portion of the male connector is inserted. A contact spring mounted between the terminals, wherein the projections 211 and 213 are provided 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. A contact spring connected in a ring shape and including a plurality of contact members 210 each having a long plate shape and a connection part 215 connecting at least two points to a side surface provided with a protruding portion of the adjacent contact member 210. 200).

Figure 2 (a) shows a perspective view of the contact member 210 constituting the contact spring 200 of the connector 1 according to the invention, Figure 2 (b) is a contact member shown in Figure 2 (b) 2 illustrates a perspective view of one contact spring 200 configured by connecting a plurality of parts, and FIG. 2 (c) is based on line A-A 'of the contact spring 200 shown in FIG. 2 (b). The cross section which shows is shown.

As shown in FIG. 2 (a), the contact member 210 constituting the contact spring 200 according to the present invention may have a plate shape having a width greater than that of the height. In addition, the contact member 210 may be provided with a pair of protrusions 211 and 213 to be in contact with the outer surface of the male terminal portion 310 and the inner surface of the female terminal portion 110 on both sides of the long width. have.

The first protrusion 211 of the pair of protrusions 211 and 213 is provided to be in contact with the inner surface of the female terminal portion 110, and the second protrusion 213 is an outer surface of the male terminal portion 310. It may be provided to be in contact with. That is, the first protrusion 211 and the second protrusion 213 connect the outer surface of the male terminal portion 310 and the inner surface of the female terminal portion 110 and may be used as an electrical connection passage.

Of course, the inclined direction of the contact member 210 is formed to be opposite to the first protrusion 211 is in contact with the outer surface of the male terminal portion 310, the second protrusion 213 is the inside of the female terminal portion (110) Contact with the side.

In the state in which the contact spring 200 is mounted on the connector 1, portions except for the protrusion of the contact member 210 are simultaneously on the outer surface of the male terminal portion 310 and the inner surface of the female terminal portion 110. If not contacted, the current supplied from the terminal portion of one terminal is supplied to the terminal portion of the other terminal in the shortest path via the pair of protrusions 211 and 213. This can be understood based on the principle that current flows toward the lower side of the resistance. Therefore, the protrusion of the contact member 210 may act as a transmission path of the current transmitted through each terminal.

As shown in FIG. 2C, the pair of protrusions 211 and 213 of the contact member 210 may be bent at a predetermined first angle θ1 smaller than 90 degrees in the opposite direction. The reason why the pair of protrusions 211 and 213 of the contact member 210 are bent at a predetermined first angle Θ1 is that each contact member 210 constituting the contact spring 200 is fastened to both terminals. This is to ensure a certain contact area on the outer surface of the male terminal portion 310 and the inner surface of the female terminal portion 110.

That is, the pair of protrusions 211 and 213 formed on one contact member 210 are bent at a predetermined first angle Θ1 smaller than 90 degrees in the opposite direction to each other so that each protrusion ( 211 and 213 are intended to allow some surface contact with the outer surface of the male terminal portion 310 and the inner surface of the female terminal portion 110 rather than point contact. As will be described later, the current flowing between both terminals can be limited to the respective protrusions, so that a certain amount of current path area can be secured.

When the male terminal 300 and the female terminal 100 are fastened with the contact spring 200 interposed therebetween, an outer surface of the male terminal portion 310 of the male terminal 300 among the contact springs 200. And a portion in contact with the inner surface of the female terminal unit 110 of the female terminal 100 may be limited to the protrusion of the contact member 210.

When only the protrusions 211 and 213 are in contact with each other, the direction of the current flowing from one terminal to the other terminal is the direction of connecting the protrusions shown in FIG. 2A, that is, the longitudinal direction of the male terminal part 310. Or it may be a direction perpendicular to the insertion direction of the male terminal portion (310).

If the supply path of the current is limited to a path connecting the pair of protrusions 211 and 213, it is possible to minimize the amount of heat generated by the contact spring 200.

In the case of the contact spring 200, which is applied to the conventional connector (1), the purpose of increasing the contact area connecting the terminal of each terminal and to enhance the mechanical stability, but to supply a current of several hundred amperes (A) Since the connector 1 for the electric vehicle is problematic in heat generation or voltage drop due to the contact spring 200, a contact spring 200 having a shape as shown in FIG. 2 is interposed between the terminals and the contact spring 200. ) Minimizes unnecessary current flow (current flow in the longitudinal direction of the contact member), and current supplied from one terminal flows to the other terminal through the shortest path of the contact spring 200. Unnecessary heat generation can be minimized and the resulting voltage drop can also be reduced.

As illustrated in FIG. 2 (b), the contact member 210 illustrated in FIG. 2 may be configured as a single contact spring 200 by connecting a plurality of rings in a single ring shape.

The plurality of contact members 210 may be connected by a wire-shaped connection part 215 having a width smaller than the width of the protrusion, and the connection part 215 may connect at least two points to adjacent contact members 210. have.

Each contact member 210 constituting the contact spring 200 shown in FIG. 2 (b) may interconnect the long side, that is, the long side, of the adjacent contact member 210 and the side surfaces of the contact member 210. have.

Specifically, the side surface of the adjacent contact member 210 may be connected to each other by two connecting portions 215 in the edge region of the long side surface on which each protrusion is formed.

The pair of protrusions 211 and 213 formed on the contact member 210 may be provided at a corresponding position of the parallel long side surface of the contact member, that is, at the center of the long side surface.

As shown in FIG. 2 (c), the connecting portion 215 may be bent in the same direction as the protrusions provided on the side surfaces of the respective connecting portions 215, and the bending angle is the bending angle of the protrusions. It may be a second angle Θ2 greater than one angle Θ1. The second angle Θ2 may also be an angle of 90 degrees or less.

By this angular condition (Θ2> Θ1), each contact member 210 does not constitute the same plane in an inclined state in a predetermined direction and is connected by the connecting portion 215 at an angle that is not parallel to one ring. It may be composed of a contact spring 200 of the form.

When each contact member 210 is connected by a second angle Θ2 smaller than 90 degrees, which is the bending angle of the connection part 215, and a ring shape is formed, the protrusions of the respective contact members 210 are formed. It may be disposed to face the outer surface of the terminal portion of the male terminal 300 and the inner surface of the female terminal portion 110 of the female terminal 100 in a diagonal direction.

3 shows a cross-sectional view of the male terminal 300 and the female terminal 100 constituting the connector 1 according to the present invention in a state in which a contact spring 200 is interposed therebetween.

When the contact spring 200 shown in FIG. 2 is mounted between the male terminal 300 and the female terminal 100, each protrusion has an outer surface of the terminal portion of the male terminal 300 and the female terminal 100. The second angle Θ2, which is the bending angle of the connecting portion 215 due to the pressurization by the inner surface of the female terminal portion 110, is narrow between the terminal portions of both terminals, so the bending angle is the second 'angle ( When the two terminals are fastened in a state in which the contact portion 210 is bent at a predetermined first angle Θ 1, and pressed in the direction of decreasing in Θ 2 ′), the outer surface of the terminal portion of the male terminal 300 is fixed. And is pressed by the inner surface of the female terminal portion 110 of the female terminal 100 to a predetermined first 'angle θ1' which is an angle smaller than the predetermined first angle Θ1.

That is, the bending angle of the protruding portion of the contact spring 200 and the bending angle of the connecting portion 215 are the first angle Θ1 and the second angle Θ2 in the free state, and the magnitude of the angle satisfies the relationship of Θ2> Θ1. However, in the state in which the contact spring 200 is mounted inside the connector 1, the bending angle of the protrusion of the contact spring 200 and the bending angle of the connecting portion 215 are the first 'angle Θ1' and the second 'angle. Is changed to (Θ2 ').

The relationship of Θ2 '> Θ1' is still maintained, but the deviation of the bending angle of the protrusion and the bending angle of the connecting portion 215 is reduced, so that the outer surface of the terminal portion of the male terminal 300 and the above-mentioned surface are elastic due to the elastic restoring force of the connecting portion 215 and the protrusion. The inner surface of the female terminal unit 110 of the female terminal 100 may be elastically supported.

Each of the metal projections 211 and 213 and the connection portion 215 bent at a predetermined angle provide elastic support for this compression, so that the outer surface of the terminal portion of the male terminal 300 and the female terminal 100 It is possible to improve the reliability of the electrical connection of the inner surface of the female terminal portion 110 of the () and at the same time minimize the amount of heat generated from the contact spring (200).

4 shows a cross-sectional perspective view of the female terminal 100 constituting the connector 1 according to the invention.

As described with reference to FIG. 1, the female terminal 100 has a female terminal portion 110 having a pipe shape having an insertion hole 111 formed therein so that the male terminal portion 310 of the male terminal 300 can be inserted therein. With the male terminal portion 310 of the male terminal 300 may be inserted into the insertion hole 111 inside the female terminal portion 110 of the female terminal 100.

The contact spring 200 described above may be interposed therebetween when the male terminal 300 and the female terminal 100 are fastened. Thus, the contact spring 200 needs to be mounted stably between both terminals.

In order to prevent a problem such that the contact spring 200 made of a thin metal material is damaged during the terminal fastening process, the female terminal 100 constituting the connector 1 according to the present invention has an inner surface of the insertion hole 111. In the mounting groove 114 can be formed.

The mounting groove 114 may be formed by forming a step portion 115 facing the inner surface of the insertion hole 111. In the process of fastening both terminals, the contact spring 200 is the male terminal ( At the same time as the insertion process of the 300, it is seated in the mounting groove 114 is not separated even in the case of the separation process of both terminals, etc., it can be maintained in the seating state.

The contact spring 200 of the connector 1 according to the present invention may be configured by connecting a plurality of elongate plate-shaped contact members 210 in a ring shape.

5 shows a perspective view of another embodiment of a contact spring according to the invention.

The protrusions 211 and 213 formed on the side surfaces of each contact member 210 may be configured to be in contact with the inner and outer surfaces of both terminals, but the width of the protrusions 211 and 213 may be in contact with the contact member 210. Since the position of the protrusions 211 and 213 is limited to the center area of the contact member 210, the male terminal 300 is fastened to the female terminal 100 or in a fastened state. The contact spring 200 according to the present invention in order to alleviate the bias or pull of the longitudinal end of the contact member 210 has two projections of each contact member 210 constituting the contact spring 200 The support part 217 may protrude from one side of the side surfaces.

The support part 217 may be bent at approximately the same bending angle in the same direction as the bending direction of the protrusion formed on the contact member 210.

The reason why the support 217 is formed only on one side of the two side surfaces in which the protrusion is formed is to limit the current supply path to the protrusion and minimize the flow of current to the support 217.

In addition, the support part 217 may be provided at both ends of the contact member 210 in the longitudinal direction because the support member 217 is provided to alleviate the longitudinal contact imbalance of the contact member 210 having a long plate shape. In detail, the support part 217 may be provided outside the connection part 215.

When the connecting portion 215 is formed at both ends of the contact member 210 in the longitudinal direction, bending may occur in the vicinity of the protruding portion, and thus, at least two of the connecting portions 215 may be spaced apart from the supporting portion 217.

That is, since the current flows toward the lower side of the resistance, when the support part 217 is formed only on one of two side surfaces of which the protrusion is formed, the current passing through the support part 217 even when the support part 217 is in contact with the terminal part of the terminal. The amount of can be minimized.

The support portion 217 may be formed to support the inner surface of the female terminal portion 110 of the female terminal 100, or may be formed to support the outer surface of the male terminal portion 310 of the male terminal 300. have. The embodiment shown in Fig. 5 shows the latter case.

Therefore, in the process of inserting the male terminal 300 into the female terminal 100, the support portion 217 supports the outer surface of the terminal portion of the male terminal 300, the contact spring 200, such as the spring is twisted or bent ) The damage problem can be alleviated and the elastic support force of the protrusion can be compensated for.

The contact spring 200 according to the present invention may be formed with opening holes each opened at a predetermined area in at least one protrusion to reinforce the elasticity of the protrusion.

The opening hole may be formed to relieve pressure required for elastic deformation of the metal protrusion, thereby reinforcing the elastic support effect.

The opening hole may be formed in all the protrusions, or may be formed in some protrusions. In addition, since the opening hole is provided to reinforce elasticity, the opening hole is preferably formed at a bent portion of the protrusion of the contact member 210.

Since the contact spring 200 according to the present invention with reference to FIGS. 1 to 5 may be made of a thin metal material, the contact spring 200 may be manufactured by punching, bending and joining a metal plate.

That is, the flat plate is punched so that each of the protrusions, the connection part 215, the support part 217 or the opening hole is formed, and each bent in accordance with the bending angle of the protrusion, the connection part 215, the support part 217 or the opening hole, One contact spring 200 may be completed by rolling and joining one ring.

Although the present specification has been described with reference to preferred embodiments of the invention, those skilled in the art may variously modify and change the invention without departing from the spirit and scope of the invention as set forth in the claims set forth below. Could be done. Therefore, it should be seen that all modifications included in the technical scope of the present invention are basically included in the scope of the claims of the present invention.
