Further, two latch insertion holes 33 d are formed in the rear portion of the side surface portion 33.

  The first connector 1100 is inserted into the insertion space 40 formed in the shell 30.

  The erroneous insertion preventing means 50 is a separate part from the shell 30. The erroneous insertion preventing means 50 is mounted on the upper surface portion 31 side of the shell 30. The erroneous insertion preventing means 50 is formed by punching and bending one metal plate.

  The erroneous insertion preventing means 50 allows the insertion when the mating connector inserted into the insertion space portion 40 is a normal mating connector, that is, the first connector 1100, and allows the mating connector to be inserted into the insertion space portion 40. When the connector is a non-regular counterpart connector, that is, the second connector 700 different from the first connector 1100, the insertion is prevented.

  The erroneous insertion preventing means 50 includes a pair of spring portions 51, a pair of connector detection portions 52, a pair of insertion prevention portions 53, and a pair of side plates 54. The spring portion 51 extends from the rear portion of the shell 30 toward the front portion side. The spring portion 51 can be elastically deformed in the vertical direction DT of the shell 30 orthogonal to the longitudinal direction DF of the shell 30. The connector detection part 52 is provided in the front end part of the spring part 51, and is extended in the up-down direction DT. The connector detection unit 52 has an inclined surface 52a. The inclined surface 52 a is inclined with respect to the bottom surface portion 32, the rear end of the inclined surface 52 a is close to the bottom surface portion 32, and the front end of the inclined surface 52 a is far from the bottom surface portion 32. The connector detector 52 is pushed out of the insertion space 40 when the first connector 1100 is inserted into the insertion space 40. The insertion preventing portion 53 is provided on the rear side of the connector detecting portion 52 of the spring portion 51 and on the center side of the insertion space portion 40 in the left-right direction DR of the shell 30. The insertion preventing portion 53 prevents the insertion when the second connector 700 is inserted into the insertion space portion 40.

  A side plate 54 is connected to the rear end portion of the spring portion 51. Two latches 54 a are formed on the side plate 54.

  The rear end portions of the pair of spring portions 51 are connected by a connecting portion 55. Two press-fit portions 56 are connected to the connecting portion 55. The press-fit portion 56 extends downward. The press-fit portion 56 is provided with a protrusion 56a and a dowel 56b. The dowel 56b suppresses the movement of the erroneous insertion preventing means 50 in the front-rear direction DF.

  The two press-fit portions 56 are press-fitted into the housing 20, and the latch 54 a is inserted into the latch insertion hole 33 d of the shell 30. The erroneous insertion preventing means 50 is fixed to the housing 20 and is mounted and held on the shell 30. A pair of connector detection parts 52, a pair of insertion prevention parts 53, etc. are arranged on the left and right of the upper surface part 31 of the shell 30.

  In order to mount the connector 100 on the printed circuit board 1200, the first and second through hole insertion portions 33a and 33b are inserted into the through holes 1201 and 1202, respectively, and the terminal portion 12 is disposed on the pad 1203. First, the second through hole insertion portions 33a and 33b may be soldered to the through holes 1201 and 1202, and the terminal portion 12 may be soldered to the pad 1203.

  As shown in FIG. 4, the first connector 1100 that is a normal mating connector with respect to the connector 100 includes a plurality of contacts 1110 arranged in two upper and lower rows, a housing 1120 that holds the plurality of contacts 1110, and a housing And a shell 1130 covering 1120. Two notches 1130 a are formed on the upper surface of the shell 1130.

  As shown in FIG. 5, the second connector 700, which is an unauthorized connector with respect to the connector 100, includes a plurality of contacts 710, a housing 720 that holds the plurality of contacts 710, and a shell 730 that covers the housing 720. It consists of The first connector 1100 and the second connector 700 are common in that their cross-sectional shapes are D-shaped, but differ in that the dimensions in the left-right direction DR are different. The dimension of the first connector 1100 in the left-right direction DR is larger than the dimension of the second connector 700 in the left-right direction DR. The vertical dimension DT of the second connector 700 may be the same as or smaller than the vertical dimension of the first connector 1100.

  As shown in FIG. 6, when the distal end portion of the first connector 1100 is inserted into the shell 30 of the connector 100, the distal end of the shell 1130 of the first connector 1100 presses the inclined surface 52 a of the connector detecting portion 52 of the erroneous insertion preventing means 50. To do. As a result, the connector detection unit 52 moves upward and exits from the insertion space 40. At this time, the spring part 51 is elastically deformed, and the insertion prevention part 53 comes out of the insertion space part 40 together with the connector detection part 52. As a result, since there is no obstacle preventing the first connector 1100 from entering the insertion space 40, the first connector 1100 can be inserted into the insertion space 40. When the first connector 1100 is inserted into the insertion space 40, the distal end portion of the lock spring piece 31 a of the connector 100 is fitted into the cutout portion 1130 a of the shell 1130, and the first connector 1100 is locked to the connector 100. Further, the contact spring piece 33c of the connector 100 contacts the shell 1130 of the first connector 1100, and the shell 30 and the shell 1130 are conducted.

  When the tip of the shell 1130 of the first connector 1100 presses the inclined surface 52a of the connector detection unit 52 of the erroneous insertion prevention means 50 and the connector detection unit 52 moves upward, the spring portion 51 bends upward. At this time, a moment occurs around the center of the side plate 54 in the spring 51, but there are two latches 54a formed on the side plate 54, and the two latches 54 respectively enter the latch insertion holes 33d. Since it is inserted, rotation of the spring portion 51 is prevented.

  As shown in FIG. 7, when the distal end portion of the second connector 700 is inserted into the shell 30 of the connector 100, the distal end of the shell 730 of the second connector 700 contacts the inclined surface 52 a of the connector detecting portion 52 of the erroneous insertion preventing means 50. Therefore, the connector detection unit 52 does not move. For this reason, the insertion prevention part 53 stays in the insertion space part 40 with the connector detection part 52. As a result, the tip of the shell 730 of the second connector 700 hits the insertion preventing portion 53, and the second connector 700 is prevented from being inserted into the insertion space portion 40 by the insertion preventing portion 53.

  Further, if the second connector 700 is forcibly inserted into the insertion space 40, the spring portion 51 is bent and the insertion prevention portion 53 moves rearward, but the rear surface 53a of the insertion prevention portion 53 immediately moves to the shell. Since it abuts against the flat surface portion 31e of 30, the insertion preventing portion 53 does not retreat any further, and erroneous insertion can be reliably prevented.

  According to this embodiment, it is possible to prevent erroneous insertion with a mating connector (for example, the second connector 700) that does not have a special shape that prevents erroneous insertion.

  Further, since the shell 30 has a flat surface portion 31e that faces the rear surface 53a of the insertion preventing portion 53 of the erroneous insertion preventing means 50 via a gap, an unauthorized counterpart connector such as the second connector 700 is inserted into the connector 1. When it is done, plastic deformation of the erroneous insertion preventing means 50 can be prevented.

  Further, when the first connector 1100, which is a normal mating connector, is inserted into the connector 100, a rotational moment is generated in the erroneous insertion preventing means 50. However, since the two latches 54a are respectively inserted into the latch insertion holes 33d. The erroneous insertion preventing means 50 can be prevented from rotating by the moment generated in the erroneous insertion preventing means 50.

  Moreover, since it is not necessary to give the 1st connector 1100 which is an other party connector the shape for preventing incorrect insertion, the enlargement of the 1st connector 1100 can be prevented.

  Further, in this embodiment, since the erroneous insertion preventing means 50 is disposed on the upper surface portion 31 side of the shell 30, in order to avoid interference between the terminal portion 12 of the contact 10 and the erroneous insertion preventing means 50, the front and rear of the housing 20 are arranged. There is no need to increase the dimension of the direction DF, and the housing 20 can be prevented from being enlarged.

  Next, the connector 200 of 2nd Embodiment of this invention is demonstrated based on FIGS.

  Portions common to the first embodiment are denoted by the same reference numerals and description thereof is omitted. Only the main differences from the first embodiment will be described below.

  The pair of spring portions 251 of the erroneous insertion preventing means 250 of the connector 200 according to the second embodiment are connected to the connecting portion 255 with their rear ends joined together. The connecting portion 255 connects the pair of side plates 54.

  In the connector 100 of the first embodiment, the erroneous insertion prevention means 50 is a separate part from the shell 30, but in the connector 300 of the third embodiment, the erroneous insertion prevention means 350 is formed integrally with the shell 330.

  The erroneous insertion prevention means 350 includes a pair of spring portions 351, a pair of connector detection portions 52, and a pair of insertion prevention portions 53. The spring part 351 is bent substantially in an S shape, the rear end part of the spring part 351 is connected to the side edge part of the upper surface part 331 of the shell 330, and the spring part 351 is folded back to the upper surface part 331 side.

The erroneous insertion preventing means 350 is formed simultaneously with the shell 330 when a shell 330 is formed by punching and bending one metal plate. At this time, the erroneous insertion preventing means 350 is formed by stamping and bending a part of the shell 330 that becomes the side surface portion 33 and the bottom surface portion 32.

  In the third embodiment, since the connector detection unit 52 is not surrounded by the shell 330, it is exposed and the connector detection unit 52 may move greatly in the left-right direction DR. For this reason, in 3rd Embodiment, the control part 333e which controls the movement of the left-right direction DR of the connector detection part 52 is provided in the upper end part of the 1st through-hole insertion part 33a.

  According to the third embodiment, the same effects as in the first embodiment can be obtained, and the erroneous insertion preventing means 350 is integrally formed with the shell 330, and the number of parts is small, so that the assembly of the connector is easy.

  In addition, since the spring portion 351 is bent in an S shape and the entire length of the spring portion 351 is long and easily bent, the first connector 1100 can be easily inserted into the insertion space portion 40.

  Next, the connector 400 of 4th Embodiment of this invention is demonstrated based on FIGS.

  Portions common to the first embodiment are denoted by the same reference numerals and description thereof is omitted. Only the main differences from the first embodiment will be described below.

  In the connector 100 of the first embodiment, the erroneous insertion preventing means 50 is disposed on the upper surface portion 31 side of the shell 30, but in the connector 400 of the fourth embodiment, the erroneous insertion preventing means 450 is the bottom surface portion 432 of the shell 430. Arranged on the side.

  The erroneous insertion prevention means 450 includes a spring part 451, a connector detection part 452, an insertion prevention part 453, and a connection part 455.

  The spring portion 451 has an L-shaped portion 451a and a U-shaped portion 451b. The L-shaped portion 451 a is substantially parallel to the bottom surface portion 432 of the shell 430. The U-shaped portion 451 b is continuous with the L-shaped portion 451 a and is substantially perpendicular to the bottom surface portion 432. The connector detection part 452 continues to the front end part of the spring part 451 and is bent into an L shape. The connector detection unit 452 has an inclined surface 452a. The insertion preventing portion 453 is continuous with the front end portion of the spring portion 451. The insertion prevention unit 453 is located rearward in the front-rear direction DF than the connector detection unit 452 and is located on the center side of the insertion space 40 in the left-right direction DR. A regulating portion 451c is provided on the L-shaped portion 451a of the spring portion 451.

  The connecting portion 455 connects the pair of spring portions 451. Two press-fit portions 456 are provided in the connecting portion 455. The press-fit portion 456 is formed with a protrusion 456a.

  A hole 432a and a notch 432b communicating with the hole 432a are formed on both sides of the bottom surface 432 of the shell 430, respectively. The shell 430 has a flat surface portion 432c facing the notch portion 432b (see FIGS. 19 and 20).

  By press-fitting the press-fitting part 456 into the housing 20, the erroneous insertion prevention means 450 is fixed to the housing 20, and a part of the spring part 451, the connector detection part 452, and the insertion prevention part 453 are inserted into the insertion space part 40 through the hole 432a. Be placed. Further, the restricting portion 451c is inserted into the notch 432b, and the restricting portion 451c faces the flat portion 432c of the shell 430 through a gap.

  As shown in FIG. 21, when the distal end portion of the first connector 1100 is inserted into the shell 430 of the connector 400, the distal end of the shell 1130 of the first connector 1100 presses the inclined surface 452a of the connector detecting portion 452 of the erroneous insertion preventing means 450. To do. As a result, the connector detection unit 452 moves downward and exits the insertion space unit 40. At this time, the insertion prevention unit 453 comes out of the insertion space unit 40 together with the connector detection unit 452. As a result, nothing obstructs the insertion of the first connector 1100 into the insertion space 40, so that the first connector 1100 can be inserted into the insertion space 40. When the first connector 1100 is inserted into the insertion space 40, the distal end portion of the lock spring piece 31 a of the connector 100 is fitted into the cutout portion 1130 a of the shell 1130, and the first connector 1100 is locked to the connector 400. Further, the contact spring piece 33c of the connector 400 contacts the shell 1130 of the first connector 1100, and the shell 430 and the shell 1130 are electrically connected.

  As shown in FIG. 22, when the distal end portion of the second connector 700 is inserted into the shell 430 of the connector 400, the distal end of the shell 730 of the second connector 700 contacts the inclined surface 452 a of the connector detecting portion 452 of the erroneous insertion preventing means 450. Therefore, the connector detection unit 452 does not move. For this reason, the insertion prevention part 453 remains in the insertion space part 40 together with the connector detection part 452. As a result, the tip of the shell 730 of the second connector 700 hits the insertion preventing portion 453, and the insertion of the second connector 700 into the insertion space portion 40 is prevented by the insertion preventing portion 453.

  If the second connector 700 is forcibly inserted, the spring portion 451 bends and the insertion preventing portion 453 moves rearward, but the restricting portion 451c abuts against the flat surface portion 432c of the shell 430. Is difficult to plastically deform.

  Portions common to the first embodiment are denoted by the same reference numerals and description thereof is omitted. Only the main differences from the first embodiment will be described below. The fifth embodiment is an embodiment in which an erroneous insertion preventing means and a shell are integrally formed, as in the third embodiment.

  In the connector 100 of the first embodiment, the erroneous insertion prevention means 50 is a separate part from the shell 30 and is arranged on the upper surface portion 31 side of the shell 30. However, in the connector 500 of the fifth embodiment, the erroneous insertion prevention means is provided. 550 is formed integrally with the shell 530 and disposed on the bottom surface portion 532 side.

The erroneous insertion prevention means 550 is formed simultaneously with the shell 530 when a single metal plate is punched and bent to form the shell 530. At this time, the erroneous insertion preventing means 550 is formed by punching and bending a part of the shell 530 that becomes the bottom surface portion 532.

  The erroneous insertion prevention means 550 includes a spring portion 551, a connector detection portion 552, and an insertion prevention portion 553. The spring portion 551 extends along the front-rear direction DF from the rear portion of the shell 530 to the front portion. The connector detection unit 552 is connected to the insertion prevention unit 553, is bent into a U shape, and has an inclined surface 552a. The insertion preventing portion 553 is continuous with the front end portion of the spring portion 551. The insertion prevention unit 553 is located rearward in the front-rear direction DF than the connector detection unit 552 and is located on the center side of the insertion space 40 in the left-right direction DR.

  According to 5th Embodiment, there exists an effect similar to 3rd Embodiment.

  Next, a connector 600 according to a sixth embodiment of the invention will be described with reference to FIGS.

  Portions common to the first embodiment are denoted by the same reference numerals and description thereof is omitted. Only the main differences from the first embodiment will be described below. The sixth embodiment is an embodiment in which the erroneous insertion preventing means and the shell are integrally formed, as in the third embodiment.

  In the connector 100 of the first embodiment, the erroneous insertion prevention means 50 is a separate part from the shell 30 and is arranged on the upper surface portion 31 side of the shell 30. However, in the connector 600 of the sixth embodiment, the erroneous insertion prevention means. 650 is formed integrally with the shell 630 and is disposed on the bottom surface portion 632 side, and a pair of erroneous insertion preventing means restricting portions 60 is provided on the shell 630.

The erroneous insertion preventing means 650 is formed simultaneously with the shell 630 when a shell 630 is formed by punching and bending one metal plate. At this time, the erroneous insertion preventing means 650 is formed by stamping and bending a part of the shell 630 that becomes the bottom surface portion 632.

  The erroneous insertion prevention means 650 includes a spring portion 651, a connector detection portion 652, and an insertion prevention portion 653. The spring part 651 extends along the front-rear direction DF from the front part of the shell 630 to the rear part. The connector detection unit 652 is connected to the insertion prevention unit 653, is bent into a U shape, and has an inclined surface 652a. The insertion preventing portion 653 is continuous with the front end portion of the spring portion 651. The insertion prevention unit 653 is located behind the connector detection unit 652 in the front-rear direction DF and is located on the center side of the insertion space 40 in the left-right direction DR.

  The erroneous insertion preventing means restricting portion 60 is formed by processing a part of the side surface portion 633 of the shell 630. The erroneous insertion preventing means restricting portion 60 includes a detecting portion 61, a movable restricting portion 62, and a spring portion 63. The detection unit 61 is continuous with the front end portion of the spring portion 63. The detection unit 61 has an inclined surface 61a. The inclined surface 61a has a shape that makes it easy to guide the first connector 1100 into the insertion space 40. The inclined surface 61a is located in front of the inclined surface 652a of the connector detection unit 652. The movable restricting portion 62 continues to the front end portion of the spring portion 63. The movable restricting portion 62 is L-shaped, and its lower portion is located below the insertion preventing portion 653. The spring part 63 extends along the front-rear direction DF from the rear part to the front part of the shell 630.

  When the first connector 1100 is inserted into the connector 600 of the sixth embodiment, first, the tip of the shell 1130 comes into contact with the inclined surface 61a of the detection portion 61 of the erroneous insertion prevention means restricting portion 60, and the detection portion 61 is inserted into the insertion space portion. The movable restricting part 62 comes out of the insertion space part 40.

  Thereafter, the tip of the shell 1130 of the first connector 1100 presses the inclined surface 652a of the connector restricting portion 652, and the connector detecting portion 652 moves downward together with the insertion preventing portion 653 and exits from the insertion space portion 40. At this time, since the movable restricting portion 62 of the erroneous insertion preventing means restricting portion 60 has already come out of the insertion space portion 40, the movable restricting portion 62 does not prevent the movement of the insertion preventing portion 653.

  As described above, since there is no obstacle to the insertion of the first connector 1100 into the insertion space 40, the first connector can be inserted into the insertion space 40.

  On the other hand, when the second connector 700 is to be inserted into the connector 600 of the sixth embodiment, the distal end of the shell 730 of the second connector 700 abuts against the insertion preventing portion 653, so that the second connector 700 is inserted into the insertion space portion 40. Cannot insert into

  The shell has the same cross-sectional shape, and inserts the tip of a third connector (not shown) that is in contact with the connector detection unit 652 but does not contact the detection unit 61 of the erroneous insertion prevention means regulating unit 60. When trying to insert into the space portion 40, the shell of the third connector presses the inclined surface 652a and pushes down the connector detecting portion 652, but the shell of the third connector is the detecting portion of the erroneous insertion preventing means regulating portion 60. Since the inclined surface of 61 does not contact 61 a, the movable restricting portion 62 is not moved, and the movable restricting portion 62 supports the insertion preventing portion 653. For this reason, the downward movement of the insertion blocking portion 653 is restricted, and as a result, the insertion of the third connector into the insertion space 40 is blocked.

  According to the sixth embodiment, the same effects as those of the third embodiment can be obtained, and it can be detected at a higher level whether the mating connector is a regular connector or a non-regular connector.
