Abstract

The present invention relates to a D-sub type connector, which can be simply installed to maximize workability since coating of each wire is cut by only attaching first and second wire connection parts to first and second mounting grooves of a support part after inserting wires into insertion holes of the first and second wire connection parts, respectively, and seam lines are connected to connection pins. Also, connection of the seam lines and the connection pins can be accurately performed and an upper end part of a cutting part vertically connected to a lower end part of a connection pin is formed as a blade while a sliding groove is formed on the upper end part so that coating is automatically cut by the blade and a seam line is moved to the sliding groove in a state of not being cut when a wire moves from an upper part toward a lower part. Thus, it is possible to connect the seam lines to the connection pins without performing a separate work by a worker in a state of minimizing damage to the seam lines.

The de-sub type connector 400 also includes a connection portion 9, a first wire connection portion 5, a second wire connection portion 7 and a fixing bolt B having the same configuration and shape as those of Figs. 4 to 15 described above do.

The de-sub type connector 400 further includes a second support portion 401.

FIG. 17 is a perspective view showing the second support portion of FIG. 16, and FIG. 18 is a rear view of FIG.

The second support portion 401 includes a second flange 411 and a support body 413 as shown in FIGS.

The second flange 411 is formed of a plate member in which mounting holes 4111 are formed at both ends.

Further, the second flange 411 has an insulator seating groove 4117 formed on the front side thereof. At this time, the insulator seating groove 4117 is extended to the support body 413, so that the shell portion 493 of the conventional connector body 409 is inserted.

A plurality of pinholes 4113 are formed on the bottom surface of the insulator seating groove 4117 of the second flange 411 at intervals.

The second flange 411 is coupled to the support body 413 on the rear surface thereof.

The support body 413 is connected to the rear surface of the second flange 411, as shown in Fig.

8 to 10, the support body 413 includes a first seating groove 4131 formed on the upper surface thereof and extending to the rear surface thereof, and a second seating groove 4132 formed on the lower surface thereof and extending to the rear surface thereof Is formed.

At this time, the first wire connecting portion 5 and the second wire connecting portion 7 are seated in the first seating groove 4131 and the second seating groove 4132.

As described above, the de-sub type connector 1 according to an embodiment of the present invention is a connector in which the wires are inserted into the respective inlet holes of the first and second wire connecting portions, and then the first and second wire connecting portions are inserted into the first seating groove Since the coating of each wire is disconnected only by attaching it to the two mounting grooves, the core wires are connected to the connection pins, so that the installation work is made simple and quick so as to maximize the workability and the connection of the core wire and the connecting pin do.

Further, in the de-sub type connector 1 of the present invention, the upper end of the cutout portion vertically connected to the rear end of the connection pin is formed by a blade, and a sliding groove is formed at the upper end thereof. When the wire moves in the direction from the upper portion to the lower portion, The core wire is automatically cut off and the core wire is moved to the sliding groove in a state in which the core wire is not cut, thereby minimizing the damage of the core wire, so that the core wire can be connected to the connection pin without performing any other operation.

In addition, the de-sub type connector 1 of the present invention is formed such that the blade is inclined downward from the outer side toward the sliding groove so that the contact area of the wire cloth and the blade is increased by using the point where the cross- So that the covering can be more efficiently incised.

Further, when the plurality of wires are pulled into the first wire connecting portion and then put into the first seating groove of the supporting portion, the disconnection of the plurality of wires and the connection of the core wires are simultaneously It is possible to further improve workability and promptness.

Further, in the de-sub type connector 1 of the present invention, the cut-out portion of the cut-out portion is curved so that when the cut-out portion is pressed by the inner wall of the inlet hole of the first wire connecting portion, By pressing the upper part of the core wire, the connection with the core wire can be made more firmly.
