[ The first contacts 2a and the second contacts 2b are connected to the insulating portion 3 so that the mounting members 22 are located at the same height with respect to the third axis direction Can be installed. In this case, the bending member 232 of the first contact 2a and the bending member 232 of the second contact 2b may be bent at different heights. The first contacts 2a and the second contacts 2b are electrically connected to the insulation part 3 so that the mounting members 22 are arranged in different rows with respect to the second axial direction ). In this case, the connecting member 23 of the first contact 2a and the connecting member 23 of the second contact 2b are formed to have different lengths with respect to the second axial direction (Y-axis direction) . The second support member 32 and the first support member 31 may be integrally formed. The insulating portion 3 may be installed on the cover 5 such that the rear surface 321 of the second supporting member 32 faces rearward (the direction of the arrow BD).

1 to 9, the blocking portion 4 shields the rear surface 3b of the insulating portion 3. As shown in FIG. Accordingly, the cut-off portion 4 can reduce the occurrence of radiation to the signal through the rear surface 3b of the insulating portion 3. The rear surface 3b of the insulating portion 3 may include a rear surface 311 of the first supporting member 31 and a rear surface 321 of the second supporting member 32. [ The shielding portion 4 shields at least one of the rear surface 311 of the first supporting member 31 and the rear surface 321 of the second supporting member 32 so that the rear surface 311 of the insulating portion 3 It is possible to prevent the radiation for the signal from being generated through the sides 3b. The blocking portion 4 may be disposed to cover the rear surface 3b of the insulating portion 3 by being coupled to the cover 5. [

The blocking portion 4 may be formed of a conductive material. In this case, the blocking portion 4 may be grounded. Accordingly, the receptacle connector 1 according to the present invention increases the blocking force for shielding the radiation of the signal through the rear surface 3b of the insulating portion 3 by using the blocking portion 4, It is possible to further reduce the occurrence of radiation to the signal through the rear surface 3b side of the antenna 3. For example, the blocking portion 4 may be formed of a metal.

The blocking portion 4 may be mounted on the substrate to be grounded through the substrate. The blocking portion 4 may be coupled to the cover 5 and may be grounded through the cover 5. In this case, the cover 5 may be formed of a conductive material and mounted on the substrate so as to be grounded. For example, the cover 5 may be formed of a metal. The blocking portion 4 may be grounded through the cover 5 by being coupled to the cover 5 to be electrically connected to the cover 5. The blocking portion 4 and the cover 5 may be integrally formed.

The blocking portion 4 may include a first blocking member 41.

The first blocking member 41 covers the rear surface 311 of the first supporting member 31. Accordingly, the first blocking member 41 can reduce the occurrence of radiation for the signal through the rear surface 311 of the first supporting member 31. [ The first blocking member 41 may be arranged to cover the rear surface 311 of the first supporting member 31 by being coupled to the cover 5. [ The first blocking member 41 may be disposed on the rear surface 311 of the first supporting member 31 so as to cover the remaining portion excluding the portion where the second supporting member 32 protrudes.

The first blocking member 41 may include a contact surface 411 (shown in FIG. 9) and an opposing surface 412 (shown in FIG. 9).

The contact surface 411 may be disposed to contact the rear surface 311 of the first support member 31. Accordingly, the contact surface 411 can prevent radiation to the signal from being generated through the rear surface 311 side of the first support member 31. The contact surface 411 may correspond to the front surface of the first blocking member 41 facing the forward direction (the direction of arrow FD).

The opposite surface 412 may be formed to be connected to the contact surface 411. The opposing face 412 may be disposed to face the contacts 2. When the first blocking member 41 is disposed below the second supporting member 32, the opposing face 412 may correspond to the upper face of the first blocking member 41.

The facing surface 412 may be formed obliquely. In this case, the inclined angle 412a between the opposing face 412 and the contact face 411 may be an obtuse angle. That is, the opposing surface 412 may be formed to be inclined toward the rear (BD arrow direction). The receptacle connector 1 according to the present invention is arranged such that even when the first blocking member 41 is disposed so as to be positioned close to the bending members 232 of the contacts 2 provided on the insulating portion 3, The first blocking member 41 can increase the insulation distance D1 (shown in Fig. 9) spaced from the bending members 232. [ In this case, the bending members 232 of the second contacts 2b may be arranged so as to be positioned close to the first blocking member 41. [ Therefore, the receptacle connector 1 according to the present invention can reduce the occurrence of the radiation to the signal by using the first blocking member 41, and can prevent the bending members 232 and the first blocking member 41 The bending members 232 and the first blocking member 41 can be prevented from being burned off by reducing the risk of short-circuiting between the first blocking member 41 and the second blocking member 41. [ The first blocking member 41 may be formed such that the portion of the first blocking member 41 that is the shortest distance between the opposing face 412 and the bending members 232 is 0.3 mm or more.

The first blocking member 41 may have a shorter length than the rear surface 311 of the first supporting member 31 with respect to the third axis direction (Z-axis direction). Accordingly, the receptacle connector 1 according to the present invention is configured such that the first blocking member 41 is fixed to the mounting member 3 of the contacts 2 provided on the insulating portion 3 with reference to the third axial direction (Z-axis direction) (D2, shown in Fig. 9) that are spaced apart from the insulators 22, as shown in Fig. In this case, the opposing face 412 of the first blocking member 41 can increase the insulation distance D2 spaced from the mounting members 22 of the second contacts 2b. The mounting members 22 of the second contacts 2b protrude from the rear surface 311 of the first supporting member 31 toward the rear side (direction of the BD arrow) to be supported by the second supporting member 32 . Therefore, the receptacle connector 1 according to the present invention can reduce the occurrence of radiation to the signal by using the first blocking member 41, but can prevent the mounting members 22 and the first blocking member 41 , It is possible to realize the burn-out prevention structure for the mounting members 22 and the first blocking member 41. [0086] The first blocking member 41 may be formed such that the portion of the first blocking member 41 that is the shortest distance between the opposing face 412 and the mounting members 22 is 0.5 mm or more.

Referring to FIGS. 1 to 11, the blocking portion 4 may include a second blocking member 42.

The second blocking member 42 covers the rear surface 321 of the second supporting member 32. Accordingly, the second blocking member 42 can reduce the occurrence of radiation for the signal through the rear surface 321 of the second supporting member 32. [ The second blocking member 42 may be disposed to cover the rear surface 321 of the second support member 32 by being coupled to the cover 5.

The second blocking member 42 may have a longer length than the rear surface 321 of the second supporting member 32 with respect to the third axis direction (Z-axis direction). In this case, the second blocking member 42 may be disposed so as to cover the entire rear surface 321 of the second supporting member 32. Accordingly, the receptacle connector 1 according to the present invention increases the blocking force for blocking the emission of the signal toward the rear surface 321 of the second supporting member 32 by using the second blocking member 42, It is possible to further reduce the occurrence of radiation to the signal toward the rear surface 321 of the second support member 32. [

The second blocking member 42 may be disposed to cover the rear surface 321 of the second supporting member 32 at a position spaced apart from the mounting members 22 in the rear direction (BD arrow direction). Accordingly, the receptacle connector 1 according to the present invention can increase the insulation distance D3 (shown in Fig. 11) that is spaced apart from the mounting members 22 by the second blocking member 42. [ In this case, the second blocking member 42 can increase the insulation distance D3 spaced from the mounting members 22 of the first contacts 2a. The mounting members 22 of the first contacts 2a protrude from the rear surface 321 of the second supporting member 32 toward the rear side in the direction of the arrow BD to be supported by the second supporting member 32 . Therefore, the receptacle connector 1 according to the present invention can reduce the occurrence of radiation to the signal by using the second blocking member 42, and can prevent the mounting members 42 and the second blocking member 42 , It is possible to implement the burn-out prevention structure for the mounting members 42 and the second blocking member 42 by reducing the risk of short-circuiting. The receptacle connector 1 according to the present invention can be implemented such that the shortest distance between the second blocking member 42 and the mounting members 22 is 0.5 mm or more. The second blocking member 42 is disposed to be spaced from the rear surface 321 of the second supporting member 32 with respect to the second axial direction (Y axis direction), so that the second blocking member 42 is spaced apart from the insulating members 22 Respectively.

The length 42b of the second blocking member 42 with respect to the second axial direction (Y-axis direction) at the same height as the mounting members 22 is shorter than the length 42a at the other height . In this case, the second blocking member 42 can further increase the insulation distance D3 spaced from the mounting members 22 of the first contacts 2a. Therefore, the receptacle connector 1 according to the present invention can reduce the occurrence of radiation to the signal by using the second blocking member 42, By increasing the insulation distance D2, it is possible to reduce the risk of short-circuiting and realize a burn-out prevention structure for the mounting members 22 and the second blocking member 42. [

Therefore, the receptacle connector 1 according to the present invention can achieve the following operational effects.

First, the receptacle connector 1 according to the present invention can simplify the manufacturing process and reduce the manufacturing time since the cover 5 is integrated.

Specifically, when the cover 5 is not integrally formed, that is, when the lower cover 51 and the upper cover 52 are formed in a separated configuration, the lower cover 51 and the upper cover 52 52 are manufactured separately, a press for manufacturing each of them must be separately provided. Therefore, the receptacle connector 1 according to the present invention can be realized by simply forming the cover 5 by forming the lower cover 51 and the upper cover 52 through a single press and bending the same, Can be simplified.

Secondly, the receptacle connector 1 according to the present invention can be realized by integrating the cover 5 with the joint 59, thereby simplifying the manufacturing process and reducing the manufacturing time.

Specifically, a Metal Injection Molding (MIM) method may be used as an example of a method used for forming the cover 5 integrally with no joint. In the case of metal injection molding, a powder mixture of powder and binder system is prepared by mixing various metal powder materials with a binder system, and the powder mixture is formed into a desired shape product through an injection molding process and the binder system is integrally The formed cover 5 is formed. When the cover 5 is integrally formed in accordance with the metal injection molding method, the metal powder used for the metal injection molding is expensive, and as the amount of the binder to be added increases to maintain the fluidity of the powder during injection molding, There is a problem that the manufacturing cost is increased and the manufacturing time is increased because it takes a long time to remove it. The receptacle connector 1 according to the present invention is formed such that the cover 5 is formed to have the joint 59 and then welded to the lower cover 51 and the upper cover 52, The manufacturing process can be simplified and the manufacturing time can be shortened.

[ Radiation may occur. Therefore, the receptacle connector 1 according to the present invention can maintain the effect of preventing radiation from occurring while simplifying the manufacturing process by forming the joint 59 on the side surface of the insulating portion 3. [

As described above, since the joint 59 is formed on the side surface of the insulating portion 3, the direction in which the blocking portion 4 is bent with respect to the cover 5 and the direction in which the upper cover 52 is bent The directions of bending with respect to the cover 51 may be perpendicular to each other. The blocking portion 4 may be bent with respect to the cover 5 on the Y-Z plane, and the upper cover 52 may be bent with respect to the lower cover 51 on the X-Z plane. The angle at which the blocking portion 4 is bent with respect to the cover 5 and the angle at which the upper cover 52 is bent with respect to the lower cover 51 may be different from each other. The blocking portion 4 may be bent by 90 ° with respect to the cover 5 and the upper cover 52 may be bent by 180 ° with respect to the lower cover 51.

The first shielding member 41 and the second shielding member 42 are bent by 90 ° since the radiation to the signal through the rear surface 3b of the insulating portion 3 is reduced.

On the other hand, since the upper cover 52 is connected to the lower cover 51 so as to protrude from the lower cover 51 in the first axial direction (X-axis direction), the third cover Bending in the direction R3. Since the upper cover 52 should be in contact with the upper surface of the lower cover 51, the upper cover 52 is bent by 180 °.

The upper cover 52 and the lower cover 51 are formed on one side of the insulation portion 3 between the first upper support member 522a and the second lower support member 512a, 15). ≪ / RTI > In this case, the bending regions 56 may be spaced apart from each other along the second axial direction (Y-axis direction).
