Description

  The present invention relates to a connector for electrical connection with a plug.

  A jack as a connector for performing electrical connection with an inserted plug is disclosed (for example, Patent Document 1).

  FIG. 13 is a cross-sectional view in which the multipolar plug 110 is inserted into the 5-pole jack 120 described in Patent Document 1. The 5-pole jack 120 has conductive terminals 123a to 123e installed at predetermined positions of the casing 121 so as to make conductive contact with the insulating casing 121 made of a synthetic resin and the respective electrodes 111 of the multipolar plug 110. And. In addition, switch terminals 124a and 124b that come into contact with the electrode 111 to detect that the plug has been inserted are provided. A plug housing space for housing the multipolar plug 110 is formed in the housing 121, and an opening 121 a that is an inlet of the plug into the plug housing space is formed on one side surface of the housing 121. The multipolar plug 110 is inserted into the housing 121 from this entrance.

  The contact portions of the conductive terminals 123a to 123e and the switch terminals 124a and 124b are located slightly projecting in the accommodation space of the multipolar plug 110 when the multipolar plug 110 is not inserted. When the multipolar plug 110 is inserted, the contact portions of the conductive terminals 123 a to 123 e and the switch terminals 124 a and 124 b are pushed back by the electrodes 111. The conductive terminals 123a to 123e and the switch terminals 124a and 124b are deformed to generate an elastic force in a direction perpendicular to the axis, and the contact portion comes into pressure contact with each electrode 111. In the connected state, the first electrode 111a is the conductive terminal 123a, the second electrode 111b is the conductive terminal 123b, the third electrode 111c is the conductive terminal 123c, the fourth electrode 111d is the conductive terminal 123d, and the fifth electrode 111e is It is in contact with the conductive terminal 123e.

  The tip of the first electrode 111a of the multipolar plug 110 has a reverse taper. In addition, an auxiliary portion 121b that restricts deformation of the conductive terminal 123a is formed on the inner wall of the casing 121 where the conductive terminal 123a is installed. Since a large contact pressure can be obtained by the elastic force between the auxiliary portion 121b and the conductive terminal 123a, the inserted multipolar plug 110 can be easily held so as not to come off.

International Publication No. 2009/072166

  However, since the auxiliary portion 121b is formed on the inner wall of the housing 121, the housing 121 is deformed in accordance with the insertion / extraction operation of the multipolar plug 110, and stress is applied to a soldering portion or the like that fixes the conductive terminal 123a.

The first side wall 25 and the second side wall 26 are provided with a first protruding portion 23 and a second protruding portion 24 at positions away from the first auxiliary portion 21 and the second auxiliary portion 22. . The first side wall portion 25 and the second side wall portion 26 on the near side where the first protruding portion 23 and the second protruding portion 24 are provided are connected by a top plate portion 28. An opening is provided between the top plate portion 27 and the top plate portion 28, so that stress when the top plate portion 27 is deformed hardly propagates to the top plate portion 28 side.

  The first projecting portion 23 and the second projecting portion 24 are formed so as to project toward the inner wall of the housing 40, and the inner member 20 is the housing at a position other than the first projecting portion 23 and the second projecting portion 24. The clearance is maintained so as not to contact the inner wall of 40. In the initial state in which the connector 1 is assembled, the first projecting portion 23 and the second projecting portion 24 may have a slight clearance on the inner wall of the housing 40. It is preferable to design the dimensions so as to contact the body 40. By doing so, it is possible to prevent the inner member 20 from rattling when the plug 60 is inserted. Further, the first projecting portion 23 and the second projecting portion 24 may be designed so as to contact the housing 40 in the initial state in which the connector 1 is assembled.

  Thus, at the initial position where the inner member 20 is disposed in the insertion space 40a, the first auxiliary portion 21 and the second auxiliary portion 22 are not in contact with the first elastic contact portion 11 and the second elastic contact portion 12.

  The connector 1 is used by being attached to an electronic device in a state where the external connection portion 35 exposed from the housing 40 is connected to a substrate (not shown) and mounted on the substrate.

  Next, the positional relationship among the inner member 20, the first elastic contact member 13, and the second elastic contact member 14 in the initial state in which the connector 1 of the present embodiment is assembled will be described.

  As shown in FIGS. 8 and 9, the first elastic contact member 13 having the first elastic contact portion 11 is disposed on one side (X1 side) from the center of the insertion space 40 a of the housing 40, and the other side The second elastic contact member 14 having the second elastic contact portion 12 is disposed on the (X2 side).

The first side wall portion 25, the second side wall portion 26, and the top plate portion 27 of the inner member 20 are in a state having a clearance from the surrounding housing 40 and the terminal member 30.

  The plug 60 shown in FIG. 10 can be inserted into the insertion space 40a of the housing 40 shown in FIG. When the plug 60 is inserted into the insertion space 40 a of the housing 40, the first elastic contact portion 11 and the second elastic contact portion 12 elastically contact the first electrode 61 of the plug 60 as shown in FIG. 10. Furthermore, as shown in FIG. 11, since the diameter of the first electrode 61 is larger, the distance between the first elastic contact portion 11 and the second elastic contact portion 12 is expanded from the initial position to the retracted position. At this time, the first elastic contact member 13 and the second elastic contact member 14 are elastically deformed with a portion in contact with the inner wall of the housing 40 as a fulcrum. Further, when the first elastic contact portion 11 and the second elastic contact portion 12 are elastically deformed and moved from the initial position to the retracted position as the plug 60 is inserted, the first auxiliary portion 21 is moved to the first elastic contact portion 11. And the second auxiliary portion 22 is in contact with the second elastic contact portion 12. At least in this state, the inner member 20 maintains a state in which almost no stress is applied to the housing 40.

  Then, the inner member 20 is elastically deformed around the top plate portion 27 so that the first elastic contact portion 11 and the second elastic contact portion 12 can be moved. At the maximum retracted position where the first electrode 61 of the plug 60 pushes up the distance between the first elastic contact portion 11 and the second elastic contact portion 12, the inner member 20 is greatly deformed to cause the first auxiliary portion 21 and the second auxiliary portion. The interval between the portions 22 is maximized. Even in this state, stress applied to the terminal member 30 and the housing 40 via the inner member 20 can be reduced.

  Since the connector 1 of the present embodiment includes the first auxiliary portion 21 and the second auxiliary portion 22, the inner member 20 is elastically deformed after the first elastic contact portion 11 and the second elastic contact portion 12 come into contact with each other. A large contact pressure can be obtained with respect to the inserted plug 60. In addition, at least in the initial stage of insertion of the plug 60, the inner member 20 urges the plug 60 in a state where no stress is applied to the housing 40, so that deformation of the housing 40 can be suppressed.

  As shown in FIG. 12, the connector 1 according to the present embodiment has the inner member 20 elastically deformed around the top plate portion 27, so that the connector 1 is elastically deformed only by the first side wall portion 25 and the second side wall portion 26. Thus, the elastic deformation portion can be lengthened and the elastic deformation amount can be lengthened.

  On the other hand, the inner member 20 is held in a state having a clearance so as not to contact the inner wall of the housing 40 at positions other than the first projecting portion 23 and the second projecting portion 24. Moreover, the 1st protrusion part 23 and the 2nd protrusion part 24 are formed in the position away from the 1st auxiliary | assistant part 21 and the 2nd auxiliary | assistant part 22, and the 1st auxiliary | assistant part 21 and the 2nd auxiliary | assistant part 22 are formed. Even when it moves, a large force is not applied to the first projecting portion 23 and the second projecting portion 24.

  Therefore, deformation of the housing 40 can be suppressed. Thereby, the stress added to the soldering part etc. to which the external connection part 35 is connected can be reduced.

  Hereinafter, the effect by having set it as this embodiment is demonstrated.

The inner member 20 is provided with a first auxiliary portion 21 on one side of the first elastic contact portion 11 and a second auxiliary portion 22 on the other side of the second elastic contact portion 12. As the plug 60 is inserted, when the first elastic contact portion 11 and the second elastic contact portion 12 are elastically deformed and moved from the initial position to the retracted position, the first auxiliary portion 21 contacts the first elastic contact portion 11. The second auxiliary portion 22 comes into contact with the second elastic contact portion 12 while in contact therewith. Further, the inner member 20 is elastically deformed so that the first elastic contact portion 11 and the second elastic contact portion 12 are movable.

  According to this configuration, since the first auxiliary portion 21 and the second auxiliary portion 22 are provided, the inner member 20 is elastically deformed and inserted after the first elastic contact portion 11 and the second elastic contact portion 12 contact each other. A large contact pressure can be obtained with respect to the plug 60. In addition, since the inner member 20 urges the plug 60 in a state where no stress is applied to the housing 40 at least in the initial stage of insertion, deformation of the housing 40 can be suppressed. Thereby, the stress added to the soldering part etc. to which the external connection part 35 is connected can be reduced.

Moreover, the 1st protrusion part 23 and the 2nd protrusion part 24 are formed in the position away from the 1st auxiliary | assistant part 21 and the 2nd auxiliary | assistant part 22, and the 1st auxiliary | assistant part 21 and the 2nd auxiliary | assistant part 22 move. In this case, a large force is not applied to the first projecting portion 23 and the second projecting portion 24. Therefore, deformation of the housing 40 can be reduced.

  The inner member 20 includes a first side wall portion 25 located on one side of the insertion space 40a, a second side wall portion 26 located on the other side of the insertion space 40a, and a first side wall portion around the insertion space 40a. 25 and a top plate portion 27 connecting the second side wall portion 26. The first auxiliary portion 21 is formed on the first side wall portion 25, the second auxiliary portion 22 is formed on the second side wall portion 26, and the top plate portion 27 is formed to be elastically deformable.

  According to this configuration, the elastically deformable portion can be lengthened and the amount of elastic deformation can be lengthened as compared with the case where the elastically deformed portion is elastically deformed only by the first side wall portion 25 and the second side wall portion 26.
