As shown in Figures 1 to 4, the de-sub connector grounding auxiliary device 10 according to the present invention is fitted to a pair of large male and female de-sub connector (20, 30) conductive body to perform a shielding function And a fixing member 150 for fixing the conductive body 100 and the pair of de-sub connectors 20 and 30.

The de-sub connector grounding assistance device 10 of the present invention serves to electrically connect and shield a pair of de-sub connectors 20 and 30 (D-sub connectors) for male and female coupling, and to fix them. .

The female de-sub connector 20 is connected to a first support 21, a first shell 23 connected to the first support 21, and a connection formed in the first shell 23. And a hole 25.

The male de-sub connector 30 is formed in the second support 31, the second shell 33 connected to the second support 31, and the second shell 33, and the connection hole ( And a connecting pin 35 fitted to 25). In general, the female and male de-sub connectors 30 are classified and standardized into five types according to the number of pins of the connection pins 35.

The de-sub connector grounding assistance device according to the present invention is a first support 21 of the female de-sub connector 20 (D-sub connector) and the second support 31 of the male de-sub connector 30 coupled male and female. A conductive body 100 coupled to the second shell 33 of the male de-sub connector 30 and the pair of de-sub connectors 20 and 30 and the conductive body coupled thereto. It includes a belt-shaped fixing member 150 surrounding the outer surface of the conductive body 100 to securely close the (100).

The conductive body 100 may include a horizontal portion 110 and a bent portion 120.

The conductive body 100 has a horizontal portion 110 in contact with the upper surface of the second shell 33 to be fitted to the second shell 33 of the male de-sub connector 30 coupled thereto, and the horizontal portion 110. ) May be formed as a bent portion 120 adjacent to the side of the second shell 33.

That is, the inner surface of the horizontal portion 110 is located on the upper surface of the second shell 33 of the de-sub connector 30, the inner surface of the bent portion 120 is located on the side of the second shell 33. .

In addition, each of the front end 111 and the rear end 113 of the horizontal portion 110 and the bent portion 120 is in contact with the second support 31 and the first support 21, the first and second Since the supports 21 and 31 are made of a metal material, they are electrically connected to the conductive body 100.

On the other hand, the conductive body 100 has a screw groove 130 is formed for coupling with one end of the fixing member 150 may be fastened to the fixing member 150 by screwing. In addition, a locking protrusion 135 may be formed to be coupled to the other end of the fixing member 150.

The fixing member 150 according to the present invention serves to make a solid coupling with the conductive body 100. Therefore, one end of the hole 151 is formed to couple to one side of the conductive body 100, the other end is formed with a ring 152 to couple to the other side of the conductive body 100.

That is, the fixing member 150 has an open lower portion and a male de-sub of the conductive body 100 in a state where one end is fixed with a screw 154 through a screw groove 130 formed on one side of the conductive body 100. Covering the lower surface of the second shell 33 of the connector 30, the hook 152 is caught and fixed to the locking projection 135 formed on the other side of the conductive body 100 again.

In addition, the fixing member 150 may also serve to electrically connect the first and second supports 21 and 31 like the conductive body 100.

In this case, the fixing member is also made of a conductive material, for example, a metal such as iron, copper, copper alloy, etc. as a main component, and the width W between the first and second supports to contact the first and second supports. It is preferable to form large.

In addition, the fixing member 150 may be configured in the form of a rectangular thin single plate, but it is preferable that a plurality of thin metal cores 153 intersect each other to increase the tensile strength.

FIG. 5 is a perspective view showing a conductive body having an inclination formed therein, and FIG. 6 is a longitudinal sectional view showing the conductive body of FIG. 5 mounted to a de-sub connector.

5 and 6, the front end 111 or the rear end 113 of the horizontal portion according to the present invention is an image light narrowing narrower toward the bottom, the front end of the bent portion (120) ( 121 or the rear end 123 is preferably in a shape that narrows toward the inside.

In this case, it is not necessary to form an inclined angle up and down. For example, the upper surface 115 of the horizontal portion 110 is formed to be larger than the width (or spacing) of the first and second supports, and the lower surface 117 is the width (W) of the first and second supports. It may be formed smaller than). As such, since the upper surface 115 of the horizontal portion 110 is formed to be larger than the width W of the first and second supports, the conductive body 100 is fitted while being pressed, so that the connection can be made stable.

7 is an exploded perspective view showing a second embodiment of the de-sub connector grounding auxiliary device according to the present invention, Figure 8 is a de-sub connector grounding auxiliary device according to the present invention coupled to the de-sub connector It is a perspective view shown.

As shown in FIGS. 7 and 8, the fixing member 150 according to the present invention has adhesive layers 155 and 155a formed at both ends of one surface thereof to be fixed to the conductive body 100, and between the adhesive layers 155 and 155a. A flexible conductive metal film 156 is formed thereon, and the other surface may be configured to form a reinforcing layer 157 that is closely coupled with the adhesive layers 155 and 155a and the metal film 156 to provide tensile strength.

In this case, unlike in Figure 1 there is an advantage that can be easily combined without forming the screw groove 130 and the locking projection 135 in the conductive body 100. However, since sufficient coupling force between the fixed and male and female de-sub connectors coupled to the conductive body 100 may not be ensured, the lengths of the adhesive layers 155 and 155a and the length of the metal film 156 should be adjusted. For example, the adhesive layers 155 and 155a may be elongated to improve the fixing force with the conductive body 100, and the fixing member 150 may be sufficiently pulled and wound to improve the bonding force between the male and female de-sub connectors.

Thus, in order to withstand the pulling force of the fixing member, it is necessary to provide sufficient tensile strength in the reinforcing layer 157. Therefore, the reinforcing layer 157 is preferably composed of a fiber or synthetic resin material.

In this case, the fixing member 150 is formed to be larger than the width W of the first and second supports so that electrical connection between the first and second supports 21 and 31 is achieved.

As described above, according to the present invention, since no bolt is used to couple the female and male de-sub connectors unlike the related art, a tool such as a driver is unnecessary and the coupling can be simplified.

And according to the present invention, there is an advantage that can maintain the shielding performance of the pair of de-sub connector to the maximum.
