In addition, the front end of the upper connection end 162 may have a shape inclined downward toward the rear, and the front end of the lower connection end 161 may have a shape inclined upward toward the rear.

That is, since the front end of the upper connection end 162 and the front end of the lower connection end 161 are formed to be inclined toward the space between each other, the front end of the second terminal 260 to be described later is connected to the upper connection end 162 and the lower end. It can be easily inserted between the ends 161.

The substrate connection end 163 is a portion extending from the rear end to the outside of the housing 110 and electrically connected to the substrate 10, and the shape of the substrate connection end 163 can be applied in various ways.

In the male connector 200, a body 210 is configured, and the lower insertion portion 220 of the male connector 200 protrudes toward the front of the body 210, so that the lower coupling groove 120 of the female connector 100 described above is ) Is inserted.

Here, in the lower insertion portion 200 of the male connector 200, a mounting hole 221 is formed through front and rear so that a second terminal 260 to be described later is installed therein.

The mounting holes 221 may be arranged in a state spaced apart along the left and right directions of the lower insertion part 200, and when the female connector 100 and the male connector 200 are coupled, the first terminal 160 as shown in FIG. 7 The upper connection end 161 and the lower connection end 162 of are inserted through the mounting hole 221 to be electrically connected to the second terminal 260.

Here, the rear end of the mounting hole 221 may have a shape whose diameter gradually decreases toward the front to prevent interference when one end of the wire 20 is inserted through the rear.

The upper insertion part 230 of the male connector 200 protrudes toward the front of the body 210 with the upper spacing part G1 of the lower insertion part 220 therebetween and is inserted into the upper coupling groove 130 to be.

The lever 240 of the male connector 200 is a portion located above the body 210, and the front end of the male connector 200 is connected to the front end of the upper insertion part 230, and the opposite rear end is vertically It is located spaced apart to enable elastic deformation.

Here, the front end of the lever 240 is integrally connected to the front end of the upper insertion portion, and the opposite rear end is positioned spaced apart from the upper portion of the body 210 with a rotation gap G2 therebetween.

In addition, at the upper rear side of the lever 240, a pressing part 241 that the user can press by hand may protrude upward. When the female connector 100 and the male connector 200 are combined, the pressing part 241 May be positioned exposed to the rear of the housing 110.

Since the rear end of the lever 240 extends in a wide width based on the front end, the movable distance of the lever 240 can be increased, and the lever 240 can be rotated with a small force.

The locking protrusion 250 of the male connector 200 protrudes from the upper end of the lever 240, and an inclined surface 251 inclined upwardly to the rear may be formed at the upper end of the lever 240.

The locking protrusion 250 is a portion that is engaged with the above-described locking projection 140, and is located at the front end of the locking projection 140 as shown in FIG. 7 when the female connector 100 and the male connector 200 are coupled.

For example, when the female connector 100 and the male connector 200 are coupled, the inclined surface 251 of the locking protrusion 250 is moved in the coupling direction while contacting the lower end of the locking protrusion 140, and in this process The rear end of the lever 240 is rotated downward based on the front end.

After that, the rear end of the lever 240 is rotated upward by its own elastic force, and the rear end of the locking protrusion 250 is positioned at the front end of the locking projection 140.

In this state, since the locking protrusion 250 is positioned at the front end of the locking protrusion 140, the female connector 100 and the male connector 200 are not separated in opposite directions.

On the other hand, when separating the female connector 100 and the male connector 200, the user presses the pressing portion 241 of the lever 240 downward, and rotates the rear end of the lever 240 downward.

At this time, the locking protrusion 250 is rotated to a height lower than the locking protrusion 140 and is converted into an unlocked state. In this state, the female connector 100 and the male connector 200 can be separated in opposite directions. I can.

On the other hand, a pair of sidewalls 211 for enclosing both ends of the lever 240 in the left-right direction may be formed to protrude upward on the upper left-right side of the body 210.

The pair of side walls 211 may prevent the rear end of the lever 240 from flowing in the left and right direction when the rear end of the lever 240 is rotated vertically.

The second terminal 260 of the male connector 200 is arranged inside the lower insertion part 220 and is manufactured using a conductive material.

Here, the second terminal 260 of the male connector 200 is disposed at a position corresponding to the aforementioned first terminal 160, and a plurality of the second terminals 260 are arranged in a state spaced apart along the left and right directions of the lower insertion unit 230. Can be.

The front end of the male connector 200 is inserted through between the lower connection end 161 and the upper connection end 162 to be electrically connected, and the front end of the wire 20 is electrically connected to the rear end of the male connector 200. It has a form that can be combined in a connected state.

As shown in FIG. 7, when the female connector 100 and the male connector 200 are coupled, the lower insertion portion 220 is inserted into the lower coupling groove 120 and the upper insertion portion 220 is inserted into the upper coupling groove 130. The part 230 is inserted.

At this time, after the rear end of the lever 240 is lowered, it is raised and returned by its own elastic force, and the locking protrusion 250 of the lever 240 is positioned at the front end of the locking projection 140.

And, the protruding end 150 of the female connector 100 is inserted into the spacing portion G1, and the front end of the protruding end 150 is positioned at the rear of the spacing portion G1, so that the female connector 100 ) And the male connector 200 are no longer moved in the mating direction and the mating is completed at the correct position.

In addition, the front end of the second terminal 260 is inserted through between the lower connection end 161 and the upper connection end 162 of the first terminal 160 to be electrically connected.

In this state, the front end of the upper connection end 162 is spaced apart from the rear end of the mounting hole 221 by an avoidance gap G3 due to the locking state of the protruding end 150, and the upper end of the upper connection end 162 is It is supported by the protruding end 150 so that the shape does not change upward.

At this time, since the front lower end of the upper connection end 162 is in elastic contact with the upper end of the second terminal 260, the connection state between the upper connection end 162 and the second terminal 260 is not changed by an external force.

As a result, in the present invention, by forming the protruding end 150 inside the female connector 100, the coupling position of the female connector 100 and the male connector 200 is not changed, so the upper connection end 162 and the male connector It is possible to prevent 200 from contacting, and since the upper end of the upper connection end 162 is supported, it is possible to prevent the connection state of the first terminal 160 and the second terminal 260 from being changed by an external force. .

In addition, in the present invention, since the rear end of the lever 240 is rotated to the locking and unlocking position based on the front end, the movable distance of the lever 240 is long, so that the lever 240 can be switched to the unlocked state with little force. In addition, since the female connector 100 and the male connector 200 can be coupled by a fitting operation, the coupling is easy.

Until now, specific embodiments of the wire connector device of the present invention have been described, but it is obvious that various embodiments can be modified without departing from the scope of the present invention.
