As shown in FIG. 10B, the fourth side 217" of the convex portion 21" of the line connector 20 is configured to be different from the inclined shape, preferably a level. And the first edge 1231" of the flange 123' of the board connector 10 is also configured to be different from the inclined shape, preferably a horizontal shape, such that when the line connector 20 is intended to be in its opposite board connector 10 When the vertical direction enters the space 17 of the board connector 10, the fourth side 217" of the convex portion 21" is the first of the system and the flange 123" Edge 1231 "will be engaged with each other, and the wire connector 20 is difficult to enter the space 10 of the connector plate 17 in a direction 10 perpendicular to the opposing board connector.

Similarly, a plurality of slits 125 may be formed on the vertical wall of the board connector 10 to increase the flexibility of the standing wall 12 itself, and a plurality of protruding ribs may be formed on the upper surface of the line connector 20 to increase the user's hand. Friction between the wire connector 20 (refer to Figures 8A and 8B).

It is to be understood that the exemplifications of the present invention are intended to be illustrative of the various embodiments of the invention described herein, without departing from the scope of the invention. It is therefore intended that all such changes be included within the scope of the following claims and their equivalents.
