Description

  The present invention relates to a shield connector attached to a case of an electric device.

  For example, in an electric vehicle or the like, a device direct connection type shield connector directly connected to a metal case is widely used. The shield connector requires a metal shield shell to be grounded to a metal case. Patent Document 1 below discloses a structure in which an elastic contact piece formed on a shield shell is brought into spring contact with the surface of the metal case so that the shield shell is grounded to the metal case.

  However, the shield connector is fixed to the metal case with bolts, and unless the bolts are tightened evenly, the shield connector is inclined with respect to the metal case. Then, some elastic contact pieces are in a state of floating from the metal case, so that the contact of the shield shell with the metal case may become unstable. In order to solve this, it is conceivable to change the configuration so that the elastic piece of the shield shell is brought into contact with the hole wall of the shaft hole of the metal case as disclosed in FIG.

JP 2008-41600 A Japanese Patent No. 2002-117947

However, even in such a case, when the connector is rotated around the tightening axis when the bolt is tightened, the shield shell 310 is also rotated and tilted integrally with the connector, and the shaft hole hole wall 300 is tilted. There is a possibility that the elastic contact piece 320 may contact obliquely (see FIG. 17).
The present invention has been completed based on the above circumstances, and by restricting the inclination of the elastic contact piece with respect to the shaft hole of the metal case, the shield shell is reliably grounded to the metal case. With the goal.

  The present invention is a shield connector attached to a metal attachment member formed with a shaft hole for attachment, a terminal mounting portion, and a hood portion provided in front of the hood portion for fitting a mating connector from the front side. A housing having a mounting flange provided at the boundary between the two parts, a terminal mounted on the terminal mounting part with a tab protruding from the hood, and a cylindrical shell body surrounding the terminal tab And a metal shield shell having a contact portion for grounding the shell body to the mounting member, and bolting the mounting flange to the mounting member while inserting the terminal mounting portion into the shaft hole. The contact portion of the shield shell is provided at the rear of the shell main body and extends along the outer wall of the terminal mounting portion. A base extending in the base, an elastic contact piece formed on the base and elastically contacting the hole wall of the shaft hole, and formed on both sides of the elastic contact piece on the base and contacting the hole wall of the shaft hole It is characterized in that it includes a pair of guide pieces.

  According to this configuration, even if a rotational force acts on the housing by bolting, the guide piece resists it. Therefore, it is possible to hold the elastic contact piece in a posture without inclination with respect to the hole wall of the shaft hole, and it is possible to stably contact the elastic contact piece with the hole wall of the shaft hole.

As an embodiment of the present invention, the following configuration is preferable.
-Provide a support part to support the base against the spring force of the elastic contact piece on the outer wall of the terminal mounting part. If the supporting portion is not provided here, the base may be pushed back against the spring force of the elastic contact piece in some cases, and the guide piece may be separated from the hole wall of the shaft hole. Then, since the posture holding function by the guide piece is lost, it becomes difficult to stabilize the posture of the elastic contact piece. In this regard, if the base portion is supported by the support portion, it is possible to restrict pushing back of the base portion, and the guide piece does not separate from the hole wall of the shaft hole. Therefore, the posture holding function by the guide piece can be surely exhibited, and thus the posture of the elastic contact piece can be stabilized.

In the case where the shaft hole for mounting is a square shape and the shape of the terminal mounting portion inserted therein is also a square shape, the contact portion of the shield shell corresponds to each of the four surfaces of the terminal mounting portion. The elastic contact pieces are respectively brought into contact with the four hole walls of the shaft hole. With such a configuration, it is possible to ensure a sufficient contact area with the shaft hole.

  According to the present invention, the inclination of the elastic contact piece with respect to the shaft hole can be restricted, and the shell main body can be reliably grounded to the mounting member.

The base 93 extends straight rearward from the rear end of the shell body 81. In terms of correspondence with the claims, it extends straight rearward along the outer surface wall 41B of the terminal mounting portion 41.

  The elastic contact piece 95 is formed by folding the rear edge portion of the base portion 93 in a U-turn shape toward the front side, and is configured to be elastically bent with the folding point as a base point. The lateral width of the elastic contact piece 95 is somewhat thinner than the width of the base portion 93. Further, a punch 96 is formed at the top of the elastic contact piece 95. The launch 96 extends in the width direction of the base 93.

  A stopper piece 94 is provided below the elastic contact piece 95. The stopper piece 94 has a function of restricting excessive bending of the elastic contact piece 95 and is formed by cutting and raising a wall surface near the base end of the base portion 93. Then, the opening 94A formed to cut and raise the stopper piece 94 has its front edge facing the boundary (boundary between the shell body 81 and the contact portion 91) L as shown in FIG. As described above, in the present embodiment, the portion around the boundary between the shell main body 81 and the contact portion 91 is reduced in thickness, and the rigidity is set lower than that in the surroundings.

  The guide pieces 97 and 98 are formed on both sides of the elastic contact piece 95 in the width direction. The guide pieces 97 and 98 are obtained by folding the left and right edges of the rear end of the base portion vertically outward. The guide pieces 97 and 98 are configured in a range from the turning point of the elastic contact piece 95 to the top of the elastic contact piece 95 (see FIGS. 8 and 10).

  The height of the guide pieces 97 and 98 is set such that when the terminal mounting portion 41 is fitted into the shaft hole 23, the tip surface 99 just contacts the hole wall 24 of the shaft hole 23 (FIG. 12). FIG. 13 and FIG. 15). Note that the top portion of the elastic contact piece 95 (that is, the launch 96) is somewhat higher than the guide pieces 97 and 98, and the top of the elastic contact piece 95 (that is, the launch 96) relative to the hole wall 24 of the shaft hole 23. 96) is always set first.

  The contact portion 91 is provided on each of the four surfaces of the shell body 81. Specifically, as shown in FIG. 11, two portions are formed on the upper surface wall 81A side and the lower surface wall 81B side, respectively, and one is formed on each of the left and right side walls 81C and 81D of the shell body 81. Yes. That is, six contact portions 91 are formed in the entire shield shell 80.

  The contact portion 91 formed on the upper surface wall 81A and the contact portion 91 formed on the lower surface wall 81B are formed at opposite positions, and have a vertically symmetrical relationship. Further, the contact portion 91 formed on the left side wall 81C and the contact portion 91 formed on the right side wall 81D are also formed at opposite positions, and have a bilaterally symmetrical relationship. In addition, each contact part 91 becomes the relationship located in the back side of each shield piece 83 just.

  Further, as shown in FIG. 9, a lock piece 99 is formed at the rear end portion of the shell main body 81. The lock piece 99 is between two adjacent contact portions 91 and extends in a cantilevered manner toward the rear.

  The shield shell 80 described above is assembled from the rear side with respect to the insertion groove 53 of the housing 40. When the shield shell 80 is inserted to the front stop position shown in FIGS. 2 to 4, there is a receiving portion (not shown) formed on the housing side. ) And the shield shell 80 is prevented from coming off.

  In this front stop position, each shield piece 83 formed in the shell body 81 is inserted into the communication hole 54 a formed in the back wall 54 of the insertion groove 53 and protrudes into the hood portion 61, so that the tab of the male terminal 31 is 32 is surrounded (see FIG. 4).

  On the other hand, each contact portion 91 is accommodated in each mounting opening 55 of the terminal mounting portion 41. At this time, the guide pieces 97 and 98 and the elastic contact piece 95 constituting the contact portion 91 are projected outward from the outer wall 51 and exposed.

  At the time of accommodation, the support protrusion 45 formed on the terminal mounting portion 41 is in contact with each base portion 93 of each contact portion 91. More specifically, as shown in FIGS. 13 and 15, support protrusions 45 are formed on each outer surface wall 41 </ b> B of the terminal mounting portion 41 corresponding to the mounting position of the base portion 93 of each contact portion 91. ing. The support protrusion 45 protrudes outward at the rear end portion of the outer surface wall 41 </ b> B of the terminal mounting portion 41, and causes the protrusion end 46 to abut on the rear surface rear end of the base portion 93. The support protrusion 45 extends a certain distance in the front-rear direction, and has a configuration in which the protruding end 46 is brought into contact with the rear end of the back surface of the base 93 for a certain distance. The operation of the support protrusion 45 will be described in detail later.

  Returning to the description of the housing 40, the mounting flange 71 is formed to protrude outward at the boundary between the terminal mounting portion 41 and the hood portion 61. The mounting flange 71 has a flat shape with a certain thickness. When viewed from the front side, the mounting flange 71 has a horizontally long shape as shown in FIG. 6, and when the shield connector 30 is assembled to the mounting wall 20, the outer surface of the mounting wall 20 (specifically, Specifically, it is configured to overlap with the hole edge of the shaft hole 23 (see FIG. 12).

  At the four corners of the mounting flange 71, circular tightening seats 72 with metal collars 72A inserted therein are formed. The bolt insertion holes 73 of these four tightening seats 72 correspond to the four bolt holes 27 formed in the mounting wall 20. The mounting flange 71 is formed with positioning bosses 74 corresponding to the positioning holes 29 formed in the mounting wall 20. From the above, when the boss 74 is fitted into the positioning hole 29, the shield connector 30 is positioned on the mounting wall 20, and the four bolt insertion holes 73 of the shield connector 30 are the four bolt holes of the mounting wall 20. 27, respectively.

  Further, a mounting groove 75 is formed on the back surface of the mounting flange 71 facing the mounting wall 20 of the housing case U. The mounting groove 75 has an annular shape that is slightly larger than the outer shape of the terminal mounting portion 41 (specifically, an annular shape that follows the outer peripheral shape of the terminal mounting portion 41), and the seal ring 100 is attached thereto. Yes.

  The seal ring 100 is made of rubber and has an annular shape that is slightly larger than the outer peripheral shape of the terminal mounting portion 41. As shown in FIGS. 4 and 5, a plurality of annular lips 103 are formed on the front side and the back side of the seal ring 100, respectively. When the shield connector 30 is assembled to the mounting wall 20, the seal ring 100 elastically contacts the wall surface around the shaft hole of the mounting wall 20 and functions to seal around the shaft hole.

  Next, the procedure for assembling the shield connector 30 to the mounting wall 20 of the housing case U will be described. Here, it is assumed that the male terminal 31 is already assembled to the shield connector 30.

  In order to assemble the shield connector 30 to the mounting wall 20, first, the position of the shield connector 30 is adjusted so that the terminal mounting portion 41 is in front of the shaft hole 23 while the terminal mounting portion 41 faces the mounting wall 20. do. If the position can be adjusted, the terminal mounting portion 41 is inserted into and fitted into the shaft hole 23 while the electric wire 35 connected to the male terminal 31 is passed through the shaft hole 23.

  Thereby, each elastic contact piece 95 is inserted into the shaft hole 23 from the tip side. As the fitting proceeds, the top of the elastic contact piece 95 enters the shaft hole 23 and comes into contact with the hole wall 24 of the shaft hole 23. Thereafter, as the fitting progresses, each elastic contact piece 95 is pushed inward through the hole wall 24 of the shaft hole 23 and elastically bends with the turning point of the tip as a base point.

  Then, when the terminal mounting portion 41 is inserted to the abutting position shown in FIG. 12, the attachment flange 71 hits the hole edge portion of the shaft hole 23, thereby completing the fitting.

  At this time, the elastic contact pieces 95 of the respective contact portions 91 formed on the four wall surfaces of the shell body 81 are in elastic contact with the four hole walls 24 of the shaft hole 23, respectively. Thus, the shell body 81 is connected to the ground with the mounting wall 20.

  After that, the assembly bolt B1 may be screwed into the mounting wall 20 screw hole 23 while being inserted into the bolt insertion hole 73 of the mounting flange 71. When four bolt tightening operations are performed, the mounting flange 71 is evenly tightened on the four sides with respect to the hole edge of the shaft hole 23. Thus, the shield connector 30 is fixed to the mounting wall 20 (completion of assembly).

  When the assembly is completed, as shown in FIG. 12, the seal ring 100 of the shield connector 30 is sandwiched between the hole edge of the shaft hole 23 and the back surface of the mounting flange 71 and compressed. As a result, the lip 103 of the seal ring 100 elastically contacts both the hole edge of the shaft hole 23 and the back surface of the mounting flange 71. As a result, the mating portion (fitting part) between the shield connector 30 and the housing case U is sealed without a gap over the entire circumference.

  After the assembly to the mounting wall 20, a mating connector (not shown) is fitted to the hood portion 61 of the shield connector 30. The mating connector is a so-called shield connector, and includes a cylindrical shield shell (not shown) similar to the shield shell 80.

  When the mating connector is fitted to the hood portion 61 of the shield connector, the shield shells of both connectors come into contact with each other. As a result of this contact, the shield shell of the mating connector and the outer conductor of the shielded electric wire in contact therewith are grounded to the mounting wall 20 together with the shield shell 80. Such a ground connection structure is also disclosed in Japanese Patent Application Laid-Open No. 2008-41600 filed by the applicant of the present application.

Next, the operation of this embodiment will be described.
When the mounting wall 20 is bolted, a force in the rotational direction acts on the shield connector 30. Therefore, the terminal mounting portion 41 of the shield connector 30 tends to tilt in the rotational direction within the shaft hole 23. For example, when a force is applied in the R arrow direction (clockwise direction) shown in FIG.

  On the other hand, the guide pieces 97 and 98 are in contact with the hole wall 24 of the shaft hole 23 and resist the force in the rotational direction. Therefore, even if the terminal mounting portion 41 and the shell main body 81 are inclined, the elastic contact piece 95 sandwiched between the guide pieces 97 and 98 is hardly inclined, and as illustrated in FIG. Maintain a parallel posture (posture maintenance function using a guide piece). As a result, the elastic contact piece 95 does not come into contact with the hole wall 24 of the shaft hole 23 but maintains a contact state with the surface. From the above, the elastic contact piece 95 can be stably brought into contact with the hole wall 24 of the shaft hole 23, and the shell body 81 can be reliably grounded to the mounting wall 20.

  As shown in FIG. 13, the contact portion 91 is formed on each of the four peripheral walls of the shell body 81, and the elastic contact piece 95 comes into contact with all the four hole walls 24 of the shaft hole 23. From the above, a sufficient contact area can be secured, and a more reliable grounding structure can be obtained.

  Further, in the present embodiment, as shown in FIGS. 14 and 15, the rear end of the base portion 93 is supported by the support protrusion 45 provided on the terminal mounting portion 41. If the support protrusion 45 is not provided, the base 93 is pushed back against the spring force of the elastic contact piece 95 in some cases, and the guide pieces 97 and 98 are separated from the hole wall 24 of the shaft hole 23. Then, since the posture holding function by the guide pieces 97 and 98 is lost, it becomes difficult to stabilize the posture of the elastic contact piece 95.

  However, in this case, it becomes possible to restrict the pushing back of the base portion 93 by the support protrusion 45, and the guide pieces 97 and 98 are not separated from the hole wall 24 of the shaft hole 23. Therefore, the posture holding function by the guide pieces 97 and 98 can be surely exhibited, and thus the posture of the elastic contact piece 95 can be stabilized.

  As shown in FIG. 13, the left and right support protrusions 45 are both on the line L1 and face each other. The upper and lower support protrusions 45 are both on the line L2 and face each other. With such a configuration, the support protrusion 45 is hardly lost by the spring force of the elastic contact piece 95. Accordingly, it is possible to reliably prevent the base 93 from being pushed back, and the posture of the elastic contact piece 95 can be further stabilized.

  Further, in the present embodiment, as described with reference to FIG. 10, the rigidity in the vicinity of the boundary between the shell main body 81 and the contact portion 91 is set to be low. Therefore, when a rotational force is applied to the shield connector 30 by the bolt tightening operation, the boundary L is deformed and only the terminal mounting portion 41 and the shell main body 81 are tilted. From the above, the contact portion 91 side does not have much force to incline it. This point is also effective in stabilizing the posture of the elastic contact piece 95.

<Other embodiments>
The present invention is not limited to the embodiments described with reference to the above description and drawings. For example, the following embodiments are also included in the technical scope of the present invention.

  (1) In the above embodiment, as an example of the shield shell 80, an example in which the tip of the base portion 93 is folded in a U-turn shape to form an elastic contact piece is illustrated. However, the shape of the shield shell is limited to the above example. Instead, for example, as shown in FIG. 16, the elastic contact piece 195 may be formed by curving the tip of the base 193. In this case, since the guide pieces 197 and 198 cannot be formed on the side of the elastic contact piece 195, the guide pieces 197 and 198 may be formed near the base end of the base portion 193 as shown in FIG.
