Description

Connector {Connecter}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector, and more particularly, to a connector that maintains stable grounding during operation or use of a vehicle.

Recently, environmental issues have become an issue, and environment-friendly automobiles have been highlighted as a target of energy conservation and minimization of environmental pollution.

Particularly, electric vehicles using electric power as a substitute for automobiles composed of existing internal combustion engines are attracting attention. Accordingly, development of related parts of electric vehicles is being actively carried out.

Because cars contain a variety of electrical devices and components, cables and connectors are required. In particular, unlike an ordinary automobile, an electric vehicle requires a high voltage of 300V or more and a large current of several tens to several hundreds of amperes. Accordingly, in order to connect a power supply, an inverter, and a motor, And cables. In addition, the connector used in an electric automobile must be capable of shielding infiltration of dust, moisture,

The cable connector according to the related art is formed of a pair of a male connector and a female connector 20 so that electrical connection is made by the combination of the male connector and the female connector.

Specifically, the female connector has a housing and a socket located inside the housing, and the male connector is provided with a contact pin for socket connection of the female connector. When the male connector and the female connector are engaged, the contact pin and the socket are connected to each other, so that the electrical connection is established.

However, when the female connector and the male connector are combined, the contact pin and the socket are excellent in structural stability, but in the case of the cable coupled to one end of the contact pin, contact may be weakened or the contact may be released by the flow.

As a result, there is a problem that the resistance between the cable and the contact pin increases and heat is generated.

SUMMARY OF THE INVENTION The present invention is conceived to solve the above-described problems and aims to provide a connector that stably maintains contact between a contact pin and a cable in a connector.

According to an aspect of the present invention, there is provided a connector according to an embodiment of the present invention. The connector includes a female connector having a socket and an arm housing accommodating the socket, a contact pin contacting the socket, A cable holder having a male connector and a female connector, the male connector being adapted to be coupled together and having a male connector for receiving a cable, the male connector being fixed to the cable and movably installed in the male housing, And an elastic member for biasing the elastic member.

According to the present invention, there are one or more of the following effects.

First, according to the present invention, when the female connector and the male connector are combined, there is an advantage of stably supplying electricity.

Second, according to the present invention, there is an advantage that the cable is elastically pressed in the direction of the contact pin so that the contact between the cable and the contact pin can be stably maintained even when flow occurs.

Thirdly, according to the present invention, there is an advantage that it is easy to manufacture with a simple structure.

The effects of the present invention are not limited to the effects mentioned above, and other effects not mentioned can be clearly understood by those skilled in the art from the description of the claims.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a perspective view of a connector according to an embodiment of the present invention, and FIG. 2 is a sectional view of a connector according to an embodiment of the present invention.

1 and 2, a connector formed of a pair of male connector 10 and female connector 20 is electrically and mechanically connected to male connector 10 and female connector 20, Connection is established.

The female connector (20) has a female housing (24) and a socket (22) housed within the female housing (24).

The female housing 24 is generally cylindrical in shape with a space therein and the male housing 14 is inserted and interposed between the inner surface of the female housing 24 and the outer surface of the socket 22.

The socket 22 is formed with a pin groove into which the contact pin 16 is inserted.

The male connector 10 includes a contact pin 16 for connecting to the socket 22 of the female connector 20 and a male housing 14 for receiving the contact pin 16.

The male housing 14 is inserted and coupled to the female housing 24 in a cylindrical shape having a space therein.

The contact pin 16 is fixed to the inside of the male housing 14 and connected to the socket 22. Specifically, the contact pin 16 is inserted into the socket 22.

The contact pin 16 is in contact with the cable 30. Specifically, one end of the cable 30 is inserted into the contact pin 16.

When the male connector 10 and the female connector 20 are engaged with each other, the contact pin 16 and the socket 22 are connected to each other and electrical connection is established.

Thus, the cable 30, the contact pin 16 and the socket 22 are located on the same axis.

A plurality of locking fingers 12 are formed on the outer surface of the male connector 10 for coupling between the female connector 10 and the female connector 20. The female connector 20 is provided with a locking finger 12, The engaging groove 26 is formed. The locking finger 12 is an elastic body having an elastic force and has a protruding portion 12a at an end thereof and the protruding portion 12a is fastened to the coupling groove 26 of the female connector 20 in an interference fit manner, Lt; / RTI >

The protruding portion 12a of the locking finger 12 fastened to the coupling groove 26 of the female connector 20 must be disengaged to release the engagement between the male connector 10 and the female connector 20. For this purpose, The male housing 14 of the connector 10 can be pulled out of the female connector 20 by pulling.

In addition, the male connector 10 receives the cable 30. For example, the male connector 10 includes a cable holder 17 for fixing the cable 30 and an elastic member 18 for applying an elastic force to the cable holder 17.

Here, the cable 30 includes a core 31 which is a conductive material and a sheath 33 of an insulating material which coats the core 31.

The cable holder 17 is fixed to the cable 30 and is movably installed in the male housing 14. [

The male housing (14) is formed with a guide groove (15) through which the cable holder (17) is guided. The guide groove 15 accommodates the cable holder 17 and the elastic member 18 and defines a space through which the cable holder 17 is moved.

The cable holder 17 is ring-shaped and the cable 30 is inserted therein.

The elastic member 18 elastically biases the cable holder 17 toward the female connector 20. For example, the elastic member 18 includes a coil spring.

The male housing 14 may be provided with a pressure holder 19 for pressing the cable 30 to secure the cable 30 securely.

Thus, there is an advantage that one end of the cable 30 (the core 31) stably maintains contact with the contact pin 16 during the flow of the connector.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It should be understood that various modifications may be made by those skilled in the art without departing from the spirit and scope of the present invention.
