FIG. 3 is a cross-sectional view showing a state in which a protection plate is mounted in a cap housing according to the present invention, FIG. 4 is a sectional view showing a state in which a plug housing is mounted in a protection plate according to the present invention, Fig. 5B is a view showing a state in which a plurality of fastening protrusions provided in the plug housing have passed through the plug retaining member, Fig. 6A shows a state in which the protecting plate is in close contact with the cap housing, Fig. The cap housing, the shield plate, and the plug housing.

First, a method of joining a connector according to the present invention will be described.

As shown in FIG. 3, the cap housing 10 and the plug housing 30 are separated from each other by a predetermined distance L ) To protect the tab terminals.

This mounting is carried out by the operator pushing the protection plate 20 into the cap housing 10 when manufacturing the connector according to the present invention.

That is, the protection plate 20 is inserted in the open upper portion of the cap housing 10 shown in Fig. By the simple insertion, the lower portion of the protection plate 20 is blocked by the plurality of escape preventing protrusions 11 provided in the cap housing 10, but the escape preventing protrusion 11 has the inclined surface from the top to the bottom , The protection plate (20) easily passes through the separation preventing protrusion (11) by pressing by the operator. As shown in FIG. 3, after the protection plate 20 has passed through the separation preventing protrusion 11, a plurality of protection plate fastening members 12 provided in the cap housing 10 are provided with a plurality of protection plates 20 The latching groove 22 is caught and held in a state of being spaced apart from the inner bottom surface of the cap housing 10 by a predetermined distance L. [ This state is a state (initial state) in which a part (tip end) of a plurality of tab terminals built in the cap housing 10 is inserted into a plurality of grooves formed in the protection plate 20, respectively.

Next, the lever housing 40 is engaged with the plug housing 30, and the plug housing 30 is mounted in the shield plate 20. 4, the insertion of the plug housing 30 by the positioning of the shield plate 20 is performed by inserting an insertion portion 34 (not shown) formed in the plug housing 30 into the holding portion 24 provided in the shield plate 20, ) Can be easily realized by inserting. Meanwhile, the guide groove 45 is mounted on a guide protrusion 15 provided inside the cap housing 10.

Then, the lever housing 40 is rotated to bring the shield plate 20 into close contact with the cap housing 10.

That is, when the operating portion 43 is rotated downward, the guide groove 45 rotates about the guide projection 15 and the plug housing 30 is rotated together with the rotation of the lever housing 40 5A by the lowering of the plug housing 30, the separating protrusion 32 moves the plurality of shielding plate engaging members 12 respectively, (22) and a plurality of shield plate engaging members (12). More specifically, the separating projection 32 provided on the plug housing 30 is composed of an inclined surface and a projecting surface at the top and bottom, and after the lower inclined surface passes through the flat portion of the protection plate engaging member 12, The projecting portion of the shield plate engaging member 12 is also pushed to the outside of the plug housing 30 so that the engaging groove 22 is separated from the shield plate engaging member 12 by pushing the flat portion to the outside of the plug housing 30.

6A, the protection plate 20 is brought into close contact with the cap housing 10 by the pressing force applied from the lever housing 40. As a result, , And each of the tab terminals is received in the plug housing (30).

5B, a plurality of fastening projections 33 provided on the plug housing 30 are provided on the plug engagement member (not shown) 23, and is continuously lowered in the direction indicated by an arrow in Fig. 5B to become the state shown in Fig. 6B, and the coupling is completed. At this time, the state of the lever housing 40 is as shown in Fig.

Next, a method of separating the connector for separating the cap housing 10 from the plug housing 30 according to the present invention will be described.

1, when the operating portion 43 of the lever housing 40 is rotated in the upward direction, the plug housing 30 and the cap housing 10 are separated from each other.

That is, when the operating portion 43 is rotated, the rotary portion 41 rotates in the receiving portion 21, and the plug housing 30 coupled to the lever housing 40 moves upward in the cap housing 10 The fixing projections 33 engaged with the plug engaging members 23 are moved upward as the plug housing 30 is lifted and the plug engaging members 23 engaged with the fixing projections 33 are moved upward, So that the entire protective plate 20 moves upward.

When the protective plate 20 reaches the projection 11 for preventing detachment of the cap housing 10 during the movement of the protection plate 20 to the upper side, So that the plug engagement member 23 can move to the inside of the space portion.

Even after this, when the upward force by the lever housing 40 is applied to the plug housing 30, the upper portion of the fixing projection 33 is inclined and the lower portion of the plug engaging member 23 is inclined So that the plug housing 30 is separated from the shield plate 20 by sliding.

When the plug housing 30 is moved upward and the upper inclined surface of the separating protrusion 32 passes the flat portion of the shielding engaging member 12, the protrusion of the shielding engaging member 12 is caught in the engaging groove 22. That is, since the upper portion of the protruding portion of the shield plate fastening member 12 is flat, the shield plate fastening member 12 is fitted to the lower portion of the latch groove 22.

The upper portion of the latching groove 22 is held in the flat portion of the protrusion of the shielding engaging member 12 while the portion of the latching groove 22 of the shielding plate 20 moves along the shielding engaging member 12, 10, the shield plate 20 is maintained in a state of being spaced apart by a predetermined distance L. [

Subsequently, when the operating portion 43 is rotated, the assembly of the plug housing 30 and the lever housing 40 is separated from the cap housing 10.

The protection plate 20 mounted in the cap housing 10 by the separation process of the cap housing 10 and the plug housing 30 can be moved up and down in the cap housing 10, 10).

Although the present invention has been described in detail with reference to the above embodiments, it is needless to say that the present invention is not limited to the above-described embodiments, and various modifications may be made without departing from the spirit of the present invention.

By using the connector according to the present invention, it is possible to protect the tab terminal at the time of conveyance of the connector, and to easily attach and detach the connector to a vehicle or the like.
