Description

Lever type connector and connector assembly using the same

The present invention relates to a lever-type connector and a connector assembly using the same, and more particularly, to a lever-type connector for coupling and separating a first connector and a second connector using a lever that moves linearly, and a connector assembly using the same .

A connector is made by installing a terminal made of a conductive material inside a housing made of an insulating material. These connectors are coupled to each other to form a connector assembly that performs electrical connection. As the number of terminals in the connector increases, the force for coupling between the connectors increases. Therefore, a lever using the principle of leverage is used.

And, depending on the position where the connector is used, it may be difficult for an operator to apply a force for fastening or separating the connectors. In this case, a lever that reciprocates in a straight line is provided so that coupling and separation between the connectors is achieved in the connector assembly. For example, this slide-type lever is used in a connector assembly for connecting between a door and a body of a vehicle.

However, if the slide lever protrudes to the outside of the housing when using such a slide type lever, damage due to external force may occur during storage or transport. If the slide lever is kept in the housing inside to prevent damage to the slide lever, it is inconvenient to separate the slide lever from the housing when it is coupled with a mating connector.

That is, the operator temporarily assembles the mating connector to the connector in a state in which the slide lever protrudes from the housing, and in this state, the slide lever is moved in the opposite direction so that the connector and the mating connector are coupled to each other. There is a problem that workability is deteriorated by doing in this way.
