Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the embodiments described herein but may be embodied in other forms. Like reference numerals designate like elements throughout the specification.

The configuration of the first embodiment of the connector assembly according to the present invention will be described in more detail with reference to the accompanying drawings.

FIG. 2 is a perspective view showing a state in which a connector assembly according to a first embodiment of the present invention is engaged, FIG. 3 is a perspective view showing a state in which a connector assembly according to a first embodiment of the present invention is disassembled, FIG. 5 is a cross-sectional view showing a connector assembly according to a first embodiment of the present invention in a disassembled state.

Referring to FIGS. 2 to 4, the connector assembly according to the first embodiment of the present invention includes a first connector 100 and a second connector 200. The first connector 100 and the second connector 100 are mutually coupled or separated.

More specifically, the first housing (110) defines the appearance of the first connector (100). For example, the first housing 110 may be formed in a polyhedral shape with one side opened, but the present invention is not limited thereto. The first housing 110 may be formed of an insulating material.

At least one guide rib 130 is provided in the first housing 110. The guide rib 130 is inserted into a guide slot 230 of the second connector 200 to guide coupling of the first connector 100 and the second connector 200. For example, the guide slot 230 protrudes outward from one surface of the first housing 110 so that the first connector 100 extends parallel to the direction in which the first connector 100 is inserted into the second connector 200 . 2 to 4, the guide rib 130 may be formed by a plurality of openings spaced from each other in a direction orthogonal to the direction in which the first connector 100 is inserted into the second connector 200 Lt; / RTI >

On the other hand, the second housing (210) defines the appearance of the second connector (200). The second housing 210 may be formed in a polyhedral shape having one side opened so that the second housing 210 can be formed with the first housing 110. The first housing 210 may be formed of an insulating material.

At least one guide slot 230 is formed on one side of the second housing 210. The guide slot 230 is inserted and guided by the guide rib 130 when the first connector 100 is coupled to the second connector 200. The guide slot 230 may be formed at a position corresponding to the guide rib 130 so that the guide rib 130 may be inserted into one side of the second housing 210. Like the guide ribs 130, the guide slots 230 are formed of a plurality of spaced apart from each other in a direction orthogonal to the direction in which the first connectors 100 are inserted into the second connector 200 .

The width W1 of the guide rib 130 in a direction orthogonal to the direction in which the first housing 110 is inserted into the second housing 210 is larger than the width W1 of the guide slot 230 W2).

Also, in this embodiment, the erroneous insertion prevention protrusion 131 is provided at the tip of the guide rib 130 in the direction in which the first housing 110 is inserted into the second housing 210. The erroneous insertion prevention protrusion 131 prevents the guide rib 130 from flowing leftward and rightward in the guide slot 230 when the guide rib 130 is inserted into the guide slot 230. [ . Therefore, the erroneous insertion prevention protrusion 131 prevents the first connector 100 and the second connector 200 from being erroneously inserted or damaged.

The width W1 'of the erroneous insertion prevention protrusion 131 is designed to be the same as the width W2 of the guide slot 230. The erroneous insertion prevention protrusion 131 is formed on the guide rib 130 so that the width W1 'of the first housing 110 gradually increases in a direction in which the first housing 110 is inserted into the second housing 210. [ It can be protruded roundly at preset curvatures on both sides of the tip of the end portion.

In this embodiment, the locking protrusion 231 is provided at the tip of the guide slot 230 in the direction in which the first housing 110 is inserted into the second housing 210. The latching protrusion 231 is a place where the erroneous insertion preventing protrusion 131 rushes in the process of being inserted into the guide slot 230. The width W2 'between the latching protrusions 231 may be set to a value less than the width W2 of the guide slot 230. [

Reference numeral 300 denotes a lever 300. The lever 300 may be pivotably coupled to pivot shafts (not shown) provided on both sides of the second housing 210. Accordingly, an external force is applied in a direction in which the first housing 110 is engaged with or separated from the second housing 210 in conjunction with the rotation of the lever 300.

Hereinafter, the operation of the ring terminal according to the first embodiment of the present invention will be described in detail with reference to the accompanying drawings.

5 to 7 are cross-sectional views illustrating a process of assembling the connector assembly according to the first embodiment of the present invention.

First, referring to FIG. 5, the first connector 100 is moved toward the second connector 200 in a predetermined insertion direction. At this time, the first housing 110 will move toward the second housing 210 substantially in the direction in which the guide rib 130 is inserted into the guide slot 230.

6, when the first housing 110 is continuously moved toward the second housing 210, the tip of the guide rib 130, that is, the erroneous insertion preventing protrusion 131, And comes into contact with the leading end of the guide slot 230, that is, the latching protrusion 231. Referring to FIG. 7, the erroneous insertion preventing protrusion 131 rides over the latching protrusion 231, so that the guide rib 130 is inserted into the guide slot 230 and moves along the guide slot 230.

That is, in this embodiment, the erroneous insertion preventing protrusion 131 rides over the latching protrusion 231 in the process of inserting the guide rib 130 into the guide slot 230, Erroneous insertion of the guide slot 130 into the guide slot 230 can be prevented. In this embodiment, the erroneous insertion preventing protrusion 131 is in contact with the inner surface of the guide slot 230 and the guide rib 130 is spaced from the inner surface of the guide slot 230, (130) moves along the guide slot (230). Therefore, in the present embodiment, while the guide rib 130 moves along the guide slot 230, the frictional force generated between the guide rib 130 and the guide slot 230 is minimized, The relative flow during the movement of the guide slot 130 along the guide slot 230 can be minimized.

Hereinafter, a connector assembly according to a second embodiment of the present invention will be described in detail with reference to the accompanying drawings.

8 is a cross-sectional view of a connector assembly of a second embodiment according to the present invention. The same components as those of the first embodiment of the present invention among the constituent elements of the present embodiment are given the same reference numerals of Figs. 2 to 6, and a detailed description thereof will be omitted.

8, in the connector assembly of the second embodiment according to the present invention, the erroneous insertion preventing protrusion 131 is formed such that the width of the first housing 110 in the direction in which the first housing 110 is inserted into the second housing 210 is reduced And can be projected obliquely at predetermined angles on both sides of the leading end of the guide rib 130. At this time, the maximum width W3 'of the erroneous insertion preventing protrusion 131 is equal to the width W2 of the guide slot 230.
