Thus, an electrical ground spring forming region for forming an electrical ground spring serving as an electrical connection between the two root portions 12a is secured, and the two electrical ground springs 14 are provided in the electrical ground spring forming region. Is formed.

  The electrical grounding spring 14 is a leaf spring-like elastic spring member extending toward the front end side (+ Y direction), and the tip end protrudes toward the inner space side of the conductive shell 4. The two electrical ground springs 14 are formed at positions symmetrical to the shell center line 30 passing through the center of the conductive shell 4 in the pitch direction. That is, one electrical ground spring 14 is formed between the root portion 12 a and the shell center line 30 of the conductive shell 4.

  In addition, on the bottom surface of the conductive shell 4, the spring portion 12 is bent outward in the pitch direction from the lock portion 12b toward the root portion 12a, and the root portion 12a is formed in the vicinity of the side surface portion, similarly to the upper surface side.

  The electrical ground spring 14 on the bottom side is a leaf spring-like elastic spring member extending toward the front end side (+ Y direction), and the tip end portion projects toward the internal space side of the conductive shell 4. Further, the two electric grounding springs 14 on the bottom side are formed at symmetrical positions with respect to the shell center line 30 passing through the center of the conductive shell 4 in the pitch direction. That is, the bottom side electrical grounding springs 14 are formed one by one between the root portion 12 a and the shell center line 30 of the conductive shell 4.

  Further, on both side surfaces of the conductive shell 4, an electric ground spring 16 that is a leaf spring-like elastic spring member and protrudes toward the inner space side of the conductive shell 4 is formed.

  As shown in FIG. 4, the USB plug connector 20 includes a plurality of contacts (not shown), an insulating material 21 that holds the plurality of contacts in a line along the pitch direction, covers the contacts and the insulating material, and a fitting portion. The plug shell 22 is formed with a fitting portion that fits into the USB standard compliant receptacle connector 2 formed with the. Further, on the upper surface of the plug shell 22 of the USB plug connector 20, two openings 24, which are substantially rectangular holes, into which the lock portion 12 b of the spring portion 12 is fitted are provided.

  The opening 24 is provided at a position facing the lock portion 12 b on the upper surface side of the conductive shell 4 when the USB plug connector 20 is fitted to the USB standard compliant receptacle connector 2. Although not shown in FIG. 4, two openings 24 are provided on the bottom surface of the plug shell 22, and the openings 24 are configured to fit the USB plug connector 20 to the USB standard compliant receptacle connector 2. In this case, the conductive shell 4 is provided at a position facing the lock portion 12b on the bottom surface side.

  Next, a case where the USB plug connector 20 is fitted to the USB standard compliant receptacle connector 2 will be described. When inserting the USB plug connector 20 into the USB standard compliant receptacle connector 2, the outer wall surface of the plug shell 22 is inserted along the inner wall surface of the conductive shell 4, and the USB plug connector 20 is fitted into the USB standard compliant receptacle connector 2. Combined state.

  In this case, the lock portion 12b of each spring portion 12 protrudes to the inner space side of the conductive shell 4, so that the two lock portions 12b on the upper surface side of the conductive shell 4 are two on the upper surface side of the plug shell 22. The two lock portions 12b on the bottom surface side of the conductive shell 4 are fitted in the two opening portions 24 on the bottom surface side of the plug shell 22. As a result, the lock portion 12b is held in a direction that prevents the plug shell 22 from being detached.

  Here, since the spring portion 12 has a shape bent outward in the pitch direction from the lock portion 12b side toward the root portion 12a side, it simply extends linearly from the lock portion side toward the root portion side. Compared with the above, since a twisting force is applied, the upper surface and the bottom surface of the plug shell 22 can be pressed more strongly, and the USB plug connector 20 fitted to the USB standard compliant receptacle connector 2 can be held stably.

  Further, since the tip of the electrical ground spring 14 protrudes toward the inner space of the conductive shell 4, when the USB plug connector 20 is fitted to the USB standard compliant receptacle connector 2, The two electrical ground springs 14 are in contact with the top surface of the plug shell 22, and the two electrical ground springs 14 on the bottom surface side of the conductive shell 4 are in contact with the bottom surface of the plug shell 22. Further, the two electric grounding springs 16 are in contact with the side surface of the plug shell 22 because the tip portions protrude toward the inner space of the conductive shell 4.

  Accordingly, the conductive shell 4 comes into contact with the plug shell 22 at six points by two electric ground springs 14 provided on the top and bottom surfaces and one electric ground spring 16 provided on each side surface. That is, since two grounding springs 14 are provided not only on the side surface of the conductive shell 4 but also on the top and bottom surfaces to increase the grounding point with the plug shell 22, the generation of electromagnetic noise due to high-speed communication signals is suppressed. be able to.

  According to the USB standard compliant receptacle connector 2 according to this embodiment, the spring reaction force is caused by the spring portion 12 being bent outward in the pitch direction from the lock portion 12b side toward the root portion 12a side. Since the twisting force is applied to the plug shell 22 and the top and bottom surfaces of the plug shell 22 are pressed more strongly, the USB plug connector 20 fitted to the USB standard compliant receptacle connector 2 can be held stably.

  In general, when the USB standard compliant receptacle connector 2 is mounted on a terminal device such as a personal computer, the USB standard compliant receptacle connector 2 is conveyed by air suction using a suction nozzle or the like. Therefore, the spring portion 12 is bent to secure an electric ground spring forming region between the root portions 12a, and the electric ground spring 14 is formed in the region, so that the rear end portion of the conductive shell 4 is more than the spring portion 12. An area for adsorbing the adsorption nozzle is secured on the side to maintain workability in the mounting operation.

  Further, the electrical ground spring 14 is provided at a symmetrical position with respect to the shell center line 30 on the top surface and the bottom surface of the conductive shell 4, so that the electrical ground spring 14 is positioned symmetrically on the top surface of the plug shell 22. And press the bottom. Therefore, the holding of the USB plug connector 20 fitted to the USB standard compliant receptacle connector 2 can be further stabilized.

  In the above-described embodiment, the case where two electrical grounding springs 14 are formed on the top and bottom surfaces of the conductive shell 4 has been described as an example, but three may be formed. In this case, the two electrical ground springs 14 are formed at positions symmetrical with respect to the shell center line 30, and the other is formed on the shell center line 30. Further, four or more electrical grounding springs 14 may be formed on the top and bottom surfaces, respectively.

  In the above-described embodiment, the case where the electrical ground spring 14 is formed between the root portions 12a has been described as an example. However, the present invention is not limited to this, and as shown in FIG. One or more electrical grounding springs 14 may be formed in the region 50 on the side surface side in the pitch direction 4. In this case, the electrical ground spring 14 may be formed only in the region 50, or the electrical ground spring 14 may be formed between the root portions 12a and in the region 50, respectively.

  Moreover, in embodiment mentioned above, although the case where the spring part 12 had the shape bent to the outer side of the pitch direction toward the root part 12a from the lock part 12b was demonstrated as an example, not only this, As shown in FIG. 6, the spring portion 12 may have a shape that is bent inward in the pitch direction (center side in the pitch direction of the conductive shell 4) from the lock portion 12 b toward the root portion 12 a. . In that case, the position of the center point of the width of the spring portion 12 in the pitch direction of the spring portion 12 at the intermediate position in the fitting direction of the root portion 12a and the lock portion 12b is the center point of the width of the root portion 12a in the pitch direction. The lock portion 12b is arranged so that it is arranged farther from the center line 38 passing through the center point in the pitch direction of the conductive shell 4 and parallel to the fitting direction than the line connecting the center point of the width in the pitch direction of the lock portion 12b. It has a shape bent inward in the pitch direction from the portion 12b toward the root portion 12a.

  Further, as shown in FIG. 6, when the spring portion 12 is bent inward in the pitch direction from the lock portion 12b toward the root portion 12a, the root portion 12a and the lock portion 12b have a width in the pitch direction of the lock portion 12b. The center point of the width in the pitch direction of the root portion 12 a is disposed closer to the center line 38 of the conductive shell 4 than the center point of the conductive shell 4. Further, in the root portion 12a, a line that passes through the center point in the pitch direction and is parallel to the fitting direction is located on the inner side in the pitch direction than the position in the pitch direction of the lock portion 12b.
