Therefore, even if the arrangement positions of the first shielding member 81 and the second shielding member 82 are exchanged, the receptacle connector R having the same structure can be made.

According to the above-described configuration, the present invention can produce the first and second shielding members with a single mold to improve productivity, and to facilitate parts management by commonizing them. In particular, since the central shielding plate and the external shielding plate are manufactured as one body, they can be disposed in the mold at once, thereby simplifying the work process. Furthermore, since the distance between the central shielding plate and the outer shielding plate is constantly maintained at a predetermined interval (standardized interval) by the connection part (connection bridge), it can be placed at an accurate position and spacing inside the mold, thereby improving product precision. .

The ground terminal 60 is manufactured integrally with the shielding members 81 and 82 as shown in FIGS. 4 and 5 . Specifically, the ground terminal 60 is integrally formed at both ends of the external shielding plate 40, respectively. More specifically, the central shielding plate 30 and the outer shielding plate 40 connected to each other as one body are integrally formed at both ends of the outer shielding plate 40, respectively. In this way, the ground terminal 60 forms a body with the central shielding plate 30 together with the external shielding plate 40, so that the signal terminals 20 are arranged in different rows together with the noise introduced from the outside of the insulating housing.

The reinforcing bar 70 is manufactured as a separate structure that is not connected to the central shield plate 30 , the external shield plate 40 , and the ground terminal 60 .

Meanwhile, in the present invention, the entire shielding members 81 and 82 are disposed to be embedded in the insulating housing 10 . That is, the central plate 31, 32, the connecting bridge 51, 52, and the outer plate 41, 42 constituting the shielding members 81 and 82 are the insulating housing 10 by insert injection molding in the mold. placed buried in

3 and 4, the insulating housing 10 has a central protrusion formed to protrude long in the longitudinal direction of the insulating housing 10 from the center disposed between the rows of the signal terminals 20. 11 is formed, and the first central plate 31 and the second central plate 32 are insert injection-molded to be embedded in the central protrusion 11 .

It is a perspective view of the integrated shielding member.

6 to 9, in the second embodiment of the present invention, the central shielding plate 30 arranged in a structure surrounding the front and rear of the signal terminals 20 arranged in each column is the same as the first embodiment described above. ) and the external shielding plate 40 are characterized in that internal and external noise that can affect the signal terminals is completely blocked by the integrated shielding member 80 made of one body, while the central shielding plate 30 The structure connecting the and the external shielding plate 40 is further improved. That is, in the first embodiment, as shown in FIG. 5 , a structure in which a connection part is connected at one end of the middle plates 31 and 32 of the first shielding member 81 and the second shielding member 82 is provided. On the other hand, in the second embodiment, as shown in FIG. 9 , it is improved to have a structure in which the connecting portions are connected at both ends of the center plates 31 and 32 . Hereinafter, the structure of the connection part which is different from the first embodiment will be mainly described.

8 and 9 , the first connecting bridge 51 of the first shielding member 81 includes first and second connecting portions 51a extending integrally from both ends of the first central plate 31 . (51b) consists of The second connecting bridge 52 of the second shielding member 82 includes third and fourth connecting portions 52a and 52b extending integrally to both ends of the second center plate 32 .

Here, the first connection part 51a and the third connection part 52a have the same configuration as the first connection bridge 51 and the second connection bridge 52 of the first embodiment ( FIG. 4 ). And the second connecting portion 51b and the fourth connecting portion 52b have the same configuration and shape as the first connecting portion 51a and the third connecting portion 52a, respectively, in the middle plate 31, 32 and the outer plates 41 and 42. ) is connected to

As described above, the first and second shielding members 81 and 82 have the first and second connecting portions 51a and 51b and the third and fourth connecting portions 52a and 52b forming a free end of the central plate 31 ) (32) is connected and fixed with the outer plates 41 and 42 at both ends, so that the posture of the center plates 31 and 32 is correct without distortion or distortion when mounted inside the mold for insert injection molding. It is possible to maintain the correct posture in position and as a result, the receptacle connector (R) which is more reliable can be manufactured.

Meanwhile, in the second embodiment of the present invention, the first shielding member 81 and the second shielding member 82 have perfectly the same shape and structure and are symmetrically insulated from the receptacle to the insulating housing 10 in the 180 degree rotational direction. It is disposed in the housing (R).

However, in order to change the arrangement positions of the first shielding member 81 and the second shielding member 82 in the second embodiment, a connecting pin section 15 in which the signal terminal 20 is not disposed is required (Fig. 7 and see Fig. 8).

That is, the second connecting portion 51b of the first shielding member 81 and the fourth connecting portion 52b of the second shielding member 82 do not contact each other between the signal terminals 20 disposed in each row, respectively.

In addition, the second connection part 51b and the fourth connection part 52b occupy a space in which one signal terminal 20 can be installed, respectively.

Therefore, even if the arrangement positions of the first shielding member 81 and the second shielding member 82 are exchanged, the second connecting portion 51b and the fourth connecting portion 52b do not overlap the signal terminal 20 .

If there is no depletion section 11, there is a problem in that the second connecting portion 51b and the fourth connecting portion 52b overlap the signal terminal 20 at the position where they are placed on the bottom surface of the insulating housing. In addition, when the depletion section 11 of each column corresponds to one area of the signal terminal 20, the first shielding member 81 and the second shielding member 82 are symmetrical to each other in the 180 degree rotational direction. It cannot be used by changing the placement position. That is, there is a problem in that it cannot be used for common use.

In the present invention, signal interference and external noise generated inside and outside the board-to-board connector are completely blocked, so that even if the distance (pitch) between signal terminals is greatly reduced, the high-frequency characteristics of the signal terminal can be greatly improved, As a result, it is possible to place more signal terminals while implementing miniaturization compared to the existing connector. In the signal terminal of the present invention, a total of 32 (32 Pins) are arranged, so that it may be possible to transmit and receive a large amount of data according to 5G communication at high speed compared to a conventional product in which a total of 12 (12 Pins) are arranged.
