Description

High voltage connector {HIGH VOLTAGE CONNECTOR}

The present invention relates to a high voltage connector, and more particularly, to a high voltage connector in which a circular terminal is integrally injection-molded into a housing.

Commonly used electronic devices are electrically connected to other electronic devices or power sources through cables. In this case, when the cable is directly connected to an electronic device or other power source and device, the work is complicated and it takes a lot of time, so that the connection is usually performed using a connector. Such a connector is typically composed of a terminal connected to an end of a cable and a housing made of an insulating material so as to wrap and protect the terminal and prevent short circuit. A connector having such a configuration is made so that the terminal and the cable are connected to each other by peeling off the insulating sheath of the wire-type cable, and then inserting the core wire from which the sheath was removed into the rear of the terminal and crimping it. The terminals assembled in the housing of the connector are electrically connected when the female/male connectors are mated to each other.

In recent years, as interest in moving means for conveniently moving a long distance other than a vehicle increases, the development of two-wheeled vehicles using an electric motor is increasing, and such two-wheeled vehicles use a high-capacity battery. In order to rapidly charge such a high-capacity battery, a connector used for high voltage is essentially used, and is formed in a circular shape for efficient contact between the connectors.

However, the connector used for such a high voltage has the following problems.

Since the terminal is assembled and formed in the housing, there is a gap between the housing and the terminal. There is a problem in that the terminal vibrates due to an external shock or vibration generated by the electronic device itself due to the clearance between the housing and the terminal, thereby causing contact failure between the connectors.

In addition, as the terminal vibrates in the housing, the temperature of the terminal rapidly increases, and there is a problem that the insulating material surrounding the terminal is melted and damaged or a fire occurs.

The interference avoiding part 125b is partially concave in the longitudinal direction of the first outer ring terminal 125. The first inner terminal 122 passes through the interference avoiding unit 125b and the interference avoiding hole 124a. In this case, the first outer terminal 124 and the first outer ring terminal 125 do not directly contact the first inner terminal 122.

Meanwhile, a first inner multi-contact spring 126 and a first outer multi-contact spring 127 may be installed inside the first inner ring terminal 123 and the first outer ring terminal 125, respectively. The first inner multi-contact spring 126 and the first outer multi-contact spring 127 have a plurality of contact points protruding toward the center, and increase contact stability with the counter terminal.

The second connector 200 has a second terminal assembly 220 installed in the second housing 210. The second housing 210 and the second terminal assembly 220 are integrally injection-molded. The second housing 210 is made of an insulating material to support the second terminal assembly 220 and secure an insulation distance between terminals constituting the second terminal assembly 220.

The second housing 210 has a second outer wall 212 and a second inner wall 213 formed on the second base 211 to constitute an overall appearance. Specifically, the second base 211 has a disk shape. The second terminal assembly 220 is installed on the second base 211. A through hole 211 ′ is formed in the center of the second base 211. The second inner terminal 221 of the second terminal assembly 220 is inserted through the through hole 211 ′ to penetrate the second base 211.

An inner space 215 is formed inside the second inner wall 213. The first inner ring terminal 123 is inserted into the inner space 215.

On the other hand, the first inner ring terminal 123 is installed on the inner surface of the first inner wall 113 of the first connector 100, but the second inner wall 213 of the second connector 200 has an outer surface. In the second outer terminal 222 of the second terminal assembly 220 is installed. Accordingly, when the first connector 100 and the second connector 200 are coupled, the first inner wall 113 and the second connector are disposed between the first inner ring terminal 123 and the second outer terminal 222. Since the inner wall 213 is located, an insulation distance is secured.

The front end of the second inner wall 213 is bent in the radial direction of the second base 211 to form a second inner covering end 213 ′. The second inner shielding end 213 ′ prevents an electric shock accident of a worker by not exposing the tip of the second outer terminal 222 of the second terminal assembly 220 to the outside. In addition, the second outer terminal 222 of the second terminal assembly 220 is prevented from being separated in the open direction of the second housing 210.

An exposed end 214 is formed at the front end of the second outer wall 212. The outer surface of the second outer terminal 222 is exposed to the outside by the exposed end 214. The front end of the exposed end 214 is in contact with the first outer covering end 112 ′ of the first outer wall 112. Since the second outer wall 212 does not extend as much as the height of the second inner wall 213 by the exposed end 214, the electrical connection between the first outer ring terminal 125 and the second outer terminal 222 Contact becomes possible.

A second outer engaging groove 222a is formed on an outer surface of the second outer terminal 222 along the circumferential direction of the second outer terminal 222. When the second housing 210 is insert-injected, the resin liquid flows into the second outer engaging groove 222a to form the second outer engaging rib 216. The second outer engaging rib 216 and the second outer engaging groove 222a are coupled so that the second outer terminal 222 is fixed without being separated between the second outer wall 212 and the second inner wall 213 The status is maintained.

Due to the coupling, a positive current flowing from the first inner terminal 122 moves to the second inner terminal 221.

The second outer terminal 222 is inserted into the outer receiving space 114. The first outer multi-contact spring 127 installed on the inner side of the first outer ring terminal 125 is in close contact with the outer surface of the second outer terminal 222 to be electrically connected. In this case, the first inner wall 113 and the second inner wall 213 are positioned between the first inner ring terminal 123 and the second outer terminal 222 to secure an insulation distance.

Due to the coupling, a negative current flowing from the first outer terminal 124 moves to the second outer terminal 222.

On the other hand, when the first inner covering end 113' of the first connector 100 contacts the bottom surface of the inner space 215, the coupling between the first connector 100 and the second connector 200 is It is completed. The first connector 100 and the second connector 200 are maintained in a coupled state by a contact pressure between the terminals. Accordingly, as the pressing force of the multi-contact spring increases, the coupling force between the first connector 100 and the second connector 200 increases.
