A guide hole 135a is formed at the side of the means contacting unit 135, and is inserted into the guide hole 135a at the side of the upper guide of the upper contacting unit 139. A stopper 139c is provided to contact the inner surface of the guide hole 135a to limit the movement of the upper contact portion 139.

The guide hole 135a of the means contacting unit 135 is formed to have a size such that the upper contacting unit 139 can be moved up and down by a predetermined range.

The means 150 is a wire connection portion 153 is connected to the wire (W); And a female terminal contact part 155 formed integrally with the wire connection part 153 and contacting the female terminal 130 when the female connector 110 of the male connector 120 is inserted into the wire connection part 153. The female terminal contact portion 155 and the connection portion of the female terminal contact portion 155 is formed with a cutout portion 157 cut off one side to prevent the bending, the reinforcement bead 159 on the opposite surface of the cut portion 157 Is formed.

The wire connection part of the means 150 is fixed in contact so that the wire (W) is energized. On the outer surface of the means 150, a reverse insertion prevention protrusion (D) protruding to prevent the reverse insertion when coupled to the male connector (120).

Of course, a groove into which the reverse insertion preventing protrusion D is inserted is formed in the male connector 120, and the groove is formed at the rear of the male connector 120.

Referring to the effect of the connector assembly 100 according to the present invention configured as described above are as follows.

13 is an operating state diagram showing the operation of the connector assembly according to the present invention.

The male connector 120 is connected to a spaced electrical device and a wire (W), and the female connector 110 is connected to a power source and a wire (W) in order to energize any electric device and power.

In order for the male connector 120 to be inserted into and energized by the female connector 110, the male connector 120 must pass through a narrow space as shown in FIG. 13.

That is, in order to pass through the narrow space, the male connector 120 passes through the narrow space in each of the separated male connectors 120 rather than in a coupled state.

The individual male connectors 120 passing through the narrow space are hooked to each other and finally coupled to the female connector 110.

That is, as shown in FIG. 5, the first male connector 121 and the second male connector 123 slide to each other and are hooked. At this time, separation of the first male connector 121 and the second male connector 123 is prevented by the locking protrusion 127 hooked to the locking step 125.

Of course, when the frictional force in the sliding direction of the locking projection 125 and the locking projection 127 is large, the departure of the sliding direction as well as the departure of the first male connector 121 and the second male connector 123 outside the sliding direction. Is prevented.

The insertion protrusion 121a of the first male connector 121 is inserted into the guide groove 127a of the second male connector 123 to guide the sliding.

Preferably the friction force in the sliding direction of the locking projections 125 and the locking projections 127 so as to slide the first male connector 121 and the second male connector 123 with a small force, the first male The insertion protrusion 121a of the connector 121 extends beyond the step 127b so that the first male connector 121 and the second male connector 123 are completely coupled.

When the insertion protrusion 121a of the first male connector 121 is completely coupled beyond the step 127b of the second male connector 123, the stepping protrusion 127b contacts the insertion protrusion 121a. Therefore, the first male connector 121 and the second male connector 123 are prevented from being separated in the sliding direction.

When the hook is coupled by the sliding of the first male connector 121 and the second male connector 123, the inclined surface 121b of the insertion protrusion 121a and the inclined surface 127c of the step 127b meet first. The insertion protrusion 121a easily moves beyond the step 127b. However, since the insertion protrusion 121a is an end portion having no inclined surface after being fully coupled, the insertion protrusion 121a is not easily released during use.

After coupling the first male connector 121 and the second male connector 123, the male connectors 121 and 123 are inserted into the female connector 110. By inserting the male connector 120, the female terminal contact portion 155 of the means 150 and the male terminal contact portion 135 of the female terminal 130 is in contact with the electricity is supplied.

Here, the female terminal contact portion 155 of the means 150 is inserted into the insertion hole (H) of the female terminal 130 is in contact with the upper contact portion 139 and the lower contact portion 137. At this time, the upper contact portion 139 is moved upward by retaining the elastic force by the entry of the female terminal contact portion 155, and the stopper 139c of the upper contact portion 139 is moved to the guide hole when the predetermined distance is moved. In contact with the inner surface of the 135a) to limit the movement of the upper contact portion 139. That is, the upper contact portion 139 is prevented from being excessively moved upward and deformed by the stopper 139c, and the contact between the upper contact portion 139, the lower contact portion 137, and the female terminal contact portion 155 is prevented. There is an advantage of increasing pressure.

In addition, since the bent portion 139b of the upper contact portion 139 is located in a direction opposite to the entry direction of the female terminal contact portion 155 of the means 150, the material cost can be reduced.

As described above, although the present invention has been described by way of limited embodiments and drawings, the present invention is not limited thereto and is intended by those skilled in the art to which the present invention pertains.
