Description

Surge Reduction Connector {SURGE REDUCING TYPE CONNECTOR}

The present invention relates to a connector, and more particularly, to a connector for reducing a surge.

Typically, the electrical system of an electric vehicle is advantageous to power up the system according to the high voltage power in terms of power efficiency or new construction of the system.

For this reason, recently developed electric vehicles use two power systems in parallel, a high voltage power system using a main power supply (42V) of 12V or more and a general vehicle power system using a 12V power source.

Here, the main power source is a special power source used in an electric vehicle and is usually applied to a system requiring high power.

On the other hand, the 12V power supply is used in the same system as a commercial vehicle.

The main power system is a drive system, an air conditioner, a heater, and most other power systems use a 12V power supply.

Meanwhile, in an electric vehicle, a secondary battery is used as a 12V power source, and a secondary battery is charged using a DC to DC converter that switches from a high voltage to a low voltage when the auxiliary battery is insufficient.

However, when using the above method, there is a problem in that the surge generated during the coupling and detachment of the connector in the 42V vehicle may seriously affect the wear of the connector terminal as well as the unit.

Disclosure of Invention An object of the present invention is to provide a surge reduction connector that can effectively suppress the occurrence of surge during connector coupling and removal, thereby minimizing the harmful effects on the wear of the connector terminal and the unit.

In order to achieve the above object, the present invention provides a surge reducing connector comprising a "-" terminal electrically connected to a "+" terminal and a male connector coupled to a female connector. )Wow; A lock switch for controlling an electrical circuit connection state between the “+” terminal and the “−” terminal according to a switching state between the “+” terminal and the “−” terminal electrically connected to the circuit; And a wire connected to each of the "+" terminal and the "-" terminal of the male connector.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. While many specific details, such as the following description and the annexed drawings, are shown to provide a more general understanding of the invention, these specific details are illustrated for the purpose of explanation of the invention and are not meant to limit the invention thereto. And a detailed description of known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.

Referring to Figure 1 will be described the configuration of the surge reducing connector according to an embodiment of the present invention.

An embodiment of the present invention includes a male connector 120 (male connector), a lock switch (Lock Switch), and wires 142 and 144 in a surge reduction connector.

The male connector 120 includes a “-” terminal 124 electrically connected to the “+” terminal 122 as shown in FIG. 1, and a female connector 110. Are coupled to the " + " sockets 112 and "-" sockets 114, respectively.

The "+" terminal 122 and the "-" terminal 124 of the male connector 120 have a "+" socket 112 and a "-" socket 114 of the female connector 110. ) And the length of the "+" terminal 122 and the length of the "-" terminal 124 so that one terminal is joined or separated before the other terminal. Form differently.

That is, as shown in FIG. 1, the length of the "+" terminal 122 is longer than that of the "-" terminal 124.

The lock switch 130 is a "+" terminal 122 and a "-" terminal 124 according to the switching state between the "+" terminal 122 and the "-" terminal 124 electrically connected to the circuit. Check the electrical circuit connection status of).

The lock switch 130 has a structure in which a user can be turned on / off.

For example, when the user presses the lock switch 130, the lock switch 130 is switched from the off state to the on state, and the electric flow path is It is done as follows.

"+" Terminal (122) ⇒ lock switch (130) ⇒ resistance (R) ⇒ "-" terminal (124)

On the contrary, when the lock switch 130 is in the OFF state, the flow of electricity supplied from the "+" terminal 122 to the "-" terminal 124 is interrupted.

As shown in FIG. 1, the wires 142 and 144 are formed of “+” wires 142 and “−” wires 144, and “+” wires 142 and “-” wires 144. ) Are connected to the "+" terminal 122 and the "-" terminal 124 of the male connector (120), respectively.

Referring to Figures 1 and 2 will be described a circuit configuration according to the coupling and disconnection state of the surge reducing connector according to an embodiment of the present invention.

FIG. 2 illustrates a circuit configuration of a lock switch 130 and a circuit configuration according to a coupling state of a male connector 120 and a female connector 110. will be.

Embodiment of the present invention is to effectively remove the surge (Surge) generated when the coupling and removal of the male connector (Male Connector) and the female connector 110 (Female Connector).

That is, as shown in FIG. 1, the lengths of the "+" terminal 122 and the "-" terminal 124 are configured differently to suppress the occurrence of surge.

If the lengths of the "+" terminal 122 and the "-" terminal 124 are the same, even if the current flow is dualized by using the resistor R, a connection failure phenomenon occurs for a very short time. The phenomenon causes sparks.

In order to prevent this problem, an embodiment of the present invention configures different lengths of the "+" terminal 122 and the "-" terminal 124 so that the "+" power source flows through the resistor R toward the "-" side. When connecting and removing the male connector 120 and the male connector 110, the one terminal is separated and combined before the other terminal. Suppress occurrence.

Assuming that the male connector 120 and the male connector 110 are coupled to each other, referring to FIG. 1, first, the male connector 120 and the male connector 110 ( To remove the female connector, the user presses the lock switch 130 (Lock Switch).

Then, as in the circuit configuration shown in FIG. 2, the current flows in two parts separately with the resistor R, and the main current flows through the resistor R. As shown in FIG.

And, when removing the male connector 120 (Male Connector) from the female connector 110 (Female Connector) "-" terminal 124 is first separated and the current flow is the resistance (R) at the "+" terminal 122 Only through.

At this time, the surge is limited as the current continues to the resistor R and only the "-" terminal 124 is separated.

In this state, when the "+" terminal 124 is even disconnected, the user may turn off the lock switch 130 by removing the force applied to the lock switch 130.

Then, the male connector 120 separated from the female connector 110 (Female Connector) is in an open state.

Meanwhile, the method of coupling the male connector 120 to the female connector 110 may be performed by removing the male connector 120 from the above-described female connector 110. You can go the opposite way.

As described above, the surge reducing connector according to the present invention effectively removes surge generated when the male connector and the female connector are coupled and removed, thereby preventing surge generation due to a large current. It has a suppressing effect.

1 is a view showing the configuration of a surge reducing connector according to an embodiment of the present invention.

FIG. 2 is a circuit diagram showing a current flow state according to a switching state of the lock switch shown in FIG.
