Description

connector assembly {CONNECTOR ASSEMBLY}

The present invention relates to a connector assembly, and to a connector assembly having an anti-eccentricity rod capable of preventing eccentricity when an upper and a lower housing are coupled using a rotary lever.

In general, a connector is coupled with a counterpart connector to perform electrical connection, and a plurality of terminals are installed inside the housing.

Recently, as a large number of terminals are installed in the housing, a large coupling force is required for coupling between connectors.

For this purpose, a lever-type connector assembly that performs coupling between connectors using a lever using the principle of a lever has been provided.

In the above-described lever-type connector assembly, a lever is installed to rotate about a hinge shaft formed on the outside of the housing of one connector, and one side of the lever is hooked to the counterpart connector to pull the counterpart connector so that the two connectors are coupled together. is becoming

A conventional connector assembly includes a lower housing, an upper housing, and a lever.

A space is formed inside the lower housing, and a pair of protrusions are formed on both sides of the lower housing.

A space into which the lower housing is inserted is formed at a lower end of the upper housing. And, on both sides of the upper housing, the pair of protrusions protrude to the outside, and a pair of guide lines cut and formed to guide the flow of the pair of protrusions along the top and bottom are formed.

In addition, the lever is formed in a 'c' shape, and both ends thereof are hingedly connected to both sides of the upper housing.

In addition, guide holes are formed on both sides of the lever. A pair of protrusions protruding from both sides of the lower housing is configured to be caught in the guide hole, and is in a state of being able to flow along the path of the guide hole. The guide hole forms a path having a predetermined length of curvature.

In general, the lever whose both ends are hingedly connected to both sides of the upper housing as described above may form a rotation angle of 90 degrees.

For example, when the lever forms 90 degrees with respect to the upper surface of the upper housing, a pair of protrusions are located at one end of the guide hole. At this time, the lower housing forms a state protruding to the lower portion of the upper housing.

In such a state, when the lever is rotated to one side and rotated to a position coincident with the upper surface of the upper housing, that is, to form 0 degrees, the pair of protrusions is linked to the rotation operation of the lever and moved along the guide hole, It is moved to the other end of the hole. In addition, the lower housing is moved upward to form a coupling with the upper housing.

Here, the conventional lever is disposed on the upper portion of the upper housing and reciprocally rotates along one side of the upper housing, thereby inducing the lower housing to move up and down, thereby inducing a coupling or releasing operation with the lower and lower housings.

However, in the related art, since the lever is reciprocally rotated to one side of the upper housing, the force for inducing fastening or coupling of the upper and lower housings is concentrated only on one side of the upper and lower housings, so that the force on the other side may be relatively less. .

Accordingly, in the related art, eccentricity is generated when the upper and lower housings are coupled, and when the lower housing is raised to be coupled to the upper housing, there is a problem in that the eccentricity is inclined to one side.

When the eccentricity occurs when the upper and lower housings are combined as described above, a lifting phenomenon or splaying occurs on the other side of the upper and lower housings, thereby causing a problem in that waterproof performance is deteriorated.
