JP 11-339870 A

By the way, when the above-described board shield connector is used in a circuit having a high frequency of a signal transmitted to the inner conductor such as a GPS antenna circuit, there is a concern that a high-frequency component is likely to leak. The
The present invention has been completed based on the above circumstances, and an object thereof is to improve the shielding performance.

  The shield connector for a board of the present invention is mounted on the board, a connector housing attached to the board, an electric conductor comprising an inner conductor, a dielectric surrounding the inner conductor, and an outer conductor surrounding the dielectric. A connector, a shield cover that is mounted on the connector housing and surrounds the electrical connector, and a contact portion that is provided on the shield cover and that can contact the outer conductor.

  By doing so, the inner conductor is shielded by being surrounded by the outer conductor and the shield cover in a double manner, so that high shielding performance can be obtained. Moreover, since the outer conductor and the shield cover are directly connected by the contact portion, higher shielding performance can be obtained. Furthermore, since the contact portion is provided on the shield cover side, if the contact portion is provided on the electrical connector side, the electrical connector is compared with a dedicated product with a contact portion as an electrical connector. Since a general-purpose product can be used, the cost can be reduced.

The following configuration is preferable as an embodiment of the present invention.
(1) The outer conductor includes a straight portion extending along the plate surface of the substrate and a bent portion bent with respect to the straight portion, and the connector housing accommodates the electrical connector. A cavity is provided so as to open in a direction along the plate surface of the substrate, and the contact portion is in contact with the bent portion. If it does in this way, a contact part can be arranged using a cavity. Accordingly, when the contact portion is brought into contact with the straight portion, compared with the need to form a notch for passing the contact portion in the portion surrounding the straight portion in the peripheral wall of the cavity, at least in the portion surrounding the straight portion. It is not necessary to form such a notch, which is effective in maintaining the protective function of the electrical connector.

(2) The shield cover is attached to the connector housing in a direction along the plate surface of the board. If it does in this way, a cavity can be utilized as an approach path of a contact part to a connector housing accompanying attachment of a shield cover. Therefore, if the mounting direction of the shield cover with respect to the connector housing is a direction perpendicular to the plate surface of the board, it is necessary to form a notch communicating with the cavity in the connector housing in order to pass the contact portion in the mounting process. In comparison, such a notch is not formed in the connector housing, and the electrical connector protection function can be sufficiently obtained.

(3) The said contact part is set as the structure currently formed in the shape of a piece which has a spring property. If it does in this way, the contact stability with respect to the electrical connector of a shield cover can be improved, and shield performance can be exhibited stably.

  According to the present invention, the shielding performance can be improved.

And a bent portion 18b extending in the vertical direction (direction perpendicular to the plate surface of the circuit board B).

  Among these, a mating inner conductor (not shown) with the mating terminal mounted on the mating connector can be brought into conductive contact with the straight portion 18a. This portion constitutes an electrical connection site for the counterpart inner conductor. The straight portion 18 a protrudes forward from the dielectric 19. On the other hand, the bent portion 18b is bent at a substantially right angle downward with respect to the straight portion 18a and protrudes further downward from the lower surface of the housing 11. A portion of the bent portion 18b protruding from the lower surface of the housing 11 is inserted into a through hole (not shown) formed in the circuit board B and soldered, so that the signal patterned on the circuit board B is obtained. The board connection tab 18c is electrically connectable to a circuit conductive path (not shown). Thus, the bent portion 18b constitutes an electrical connection portion and a fixing portion for the circuit board B.

  The dielectric 19 is made of an insulating synthetic resin, is formed in a substantially block shape having an L-shaped cross section, and includes an inner conductor housing chamber 19a in which the inner conductor 18 can be housed. The inner conductor accommodating chamber 19a penetrates the dielectric 19 in the front-rear direction, and is also formed so as to open on the lower surface side while leaving a front stop wall. The inner conductor 18 can be press-fitted and held by the press-fitting pieces 18d formed on both side edges of the terminal connection portion of the inner conductor 18 on the side surface of the inner conductor accommodating chamber 19a.

  The outer conductor 20 is formed into a substantially cylindrical shape having a substantially L-shaped cross section according to the outer shape of the dielectric 19 as a whole by press-molding a metal plate. It is possible to surround the circumference. The outer conductor 20 includes a straight portion 20a that extends along the front-rear direction, like the inner conductor 18, and a bent portion 20b that is bent with respect to the straight portion 20a and extends along the vertical direction.

  Among these, as shown in FIG.1 and FIG.3, the straight part 20a has comprised the substantially cylindrical shape opened to the front, and the other party outer conductor (not shown) in the other party terminal can carry out electrical contact. . This portion constitutes an electrical connection portion for the counterpart outer conductor.

A portion of the straight portion 20a that protrudes forward from the dielectric 19 is disposed to face the straight portion 18a of the inner conductor 18 in a radially outward direction with a predetermined space therebetween. A pair of metal lances 20c that can be locked to the lance locking portion on the housing 11 side are cut and raised from both side surfaces of the cylindrical portion constituting the straight portion 20a (FIG. 3). Thereby, the electrical connector 12 is prevented from coming off from the housing 11.

  On the other hand, as shown in FIG. 1, the bent portion 20b is bent substantially downward at a right angle to the straight portion 20a (on the side of the circuit board B), and has a substantially cylindrical shape that opens downward while communicating with the straight portion 20a. I am doing. The bent portion 20 b includes a cylindrical portion 21 and a pair of board connection tabs 22 that further protrude downward from the lower edges of the side walls 21 a of the cylindrical portion 21, and of these, the board connection tab 22 is the housing 11. It protrudes further downward from the lower surface of the. The board connection tab 22 is inserted into a through hole (not shown) formed in the circuit board B and soldered, whereby a ground circuit conductive path (not shown) patterned on the circuit board B. ) Can be electrically connected. Thus, the bent portion 20b constitutes an electrical connection portion and a fixing portion for the circuit board B. The two board connection tabs 22 are arranged at positions shifted from each other in the front-rear direction and also from the front and rear with respect to the board connection tab 18 c of the inner conductor 18.

  In addition, a pair of protruding pieces 21c project from the side edges of the rear wall 21b of the tubular portion 21 of the bent portion 20b, and a pair of protruding pieces 21c extends from the rear edges of the side walls 21a. A pair of lock pieces 21d are formed to protrude rearward at positions corresponding to the upper and lower sides. The rear wall 21b is substantially open in parallel with the upper wall of the straight portion 20a and allows the dielectric 19 to enter from the rear into the outer conductor 20 before the dielectric 19 is assembled in the outer conductor 20. After the dielectric 19 is assembled, it is bent with respect to the upper wall and is in a closed state along the vertical direction. In the closed state, the upper and lower lock pieces 21d are engaged with the protruding piece 21c, so that the rear wall 21b is opened and held in a restricted state.

Conductive connection is possible with the mating terminal of the mating connector fitted inside.

  As shown in FIGS. 1 to 3, the shield cover 13 is formed in a substantially box shape with the lower surface side and the front surface side opened as a whole, by press forming a metal plate. It is possible. The shield cover 13 is attached to the housing 11 from the upper side to the lower side along the vertical direction (direction orthogonal to the plate surface of the circuit board B). It corresponds with the mounting direction of the housing 11 with respect to. The shield cover 13 can surround the outer peripheral surface of the housing 11 from four directions, upper, rear, and both sides, and includes an upper plate 23 and a pair of side plates 24 bent downward from both side edges of the upper plate 23. The rear plate 25 is bent downward from the rear edge of the upper plate 23.

In the mounted state, the front ends of the upper plate 23 and the side plates 24 are arranged at substantially the same position as the rear end of the overhanging portion 15b in the housing 11 (FIG. 2), and the inner conductor 18 and the outer conductor 20 in the electrical connector 12 are arranged. The straight portions 18a and 20a are located in front of the front ends (FIG. 1). Thus, the electrical connector 12 is surrounded by the shield cover 13 over almost the entire length. Further, the both side plates 24 are cut out along the outer shape of the substrate fixing portion 16, respectively, and the lower edge and the front edge thereof can abut against the outer surface of the substrate fixing portion 16.

  As shown in FIGS. 1 and 3, substrate fixing pieces 26 are provided so as to protrude downward from the lower ends of the side plates 24 and the rear plate 25, respectively. Each board fixing piece 26 is formed to be wider than each board connection tab 18c, 22 of the electrical connector 12, but the length dimension is equivalent to each board connection tab 18c, 22. The board fixing pieces 26 of the side plates 24 and the board fixing pieces 26 of the rear plate 25 are arranged at positions shifted forward and backward, and the board connection tabs 18 c and 22 are arranged between the board fixing pieces 26. ing.

  As shown in FIG. 1, the shield cover 13 is provided with a contact piece 27 that can come into contact with the outer conductor 20 constituting the electrical connector 12. The contact piece 27 is formed in a cantilever shape by partially raising the rear plate 25 of the shield cover 13. The contact piece 27 extends substantially along the vertical direction and has a slanted posture with a free end protruding toward the housing 11 side. The contact piece 27 has a base end portion on the lower side and a free end portion on the upper side, and can be elastically deformed with the lower base end portion as a fulcrum, and the free end portion in the front-rear direction along with the elastic deformation. It is designed to be displaced along. Further, the contact piece 27 is disposed at a substantially central position in the width direction of the rear plate 25 and at a lower portion, and a base end portion thereof is disposed at a lower end position of the rear plate 25.

  In a state where the shield cover 13 is mounted on the housing 11, the contact piece 27 is disposed at the rear end position in the cavity 17, and with respect to the rear wall 21 b of the bent portion 20 b of the outer conductor 20 of the electrical connector 12. It comes in contact from the rear side. The contact position of the contact piece 27 on the rear wall 21b of the bent portion 20b is the center position in the width direction, and the contact piece 27 is set so as not to interfere with both the projecting pieces 21c and the lock pieces 21d.

  As shown in FIGS. 1 and 4, the housing 11 is formed with a notch 28 through which the contact piece 27 can be inserted in the process of mounting the shield cover 13. The notch 28 is formed in accordance with the passage path of the contact piece 27 in the mounting process of the shield cover 13, and is formed substantially straight along the vertical direction at the rear end position in the housing 11. The cutout 28 communicates with the rear end position of the cavity 17 and opens in the vertical direction and rearward. The notch 28 is set to have a dimension in the front-rear direction larger than that of the contact piece 27, so that the contact piece 27 does not interfere with the periphery of the notch 28 during the mounting process, and the contact piece 27 is almost bent. It does not occur. In addition, the rear wall 21b of the outer conductor 20 in the electrical connector 12 faces the notch 28.

  This embodiment has the structure as described above, and the operation thereof will be described subsequently. After the electrical connector 12 and the shield cover 13 are sequentially attached to the housing 11 and the board shield connector 10 is assembled, the board shield connector 10 is attached to the circuit board B. First, a method for assembling the board shield connector 10 will be described.

  The electrical connector 12 is inserted into the cavity 17 of the housing 11 from the rear along the front-rear direction. Then, the straight portion 20 a of the outer conductor 20 in the electrical connector 12 protrudes into the hood portion 15 after passing through the cavity 17. When the electrical connector 12 reaches the normal depth, as shown in FIG. 5, the bent portion 20b of the outer conductor 20 is brought into contact with the front stop wall 17a of the cavity 17 and stopped, and the metal lance 20c. By locking against the lance locking portion, the electrical connector 12 is prevented from coming off (FIG. 3).

  Subsequently, in the state shown in FIGS. 5 and 6, the shield cover 13 is put on the housing 11 along the vertical direction from above. Then, both side plates 24 are brought into sliding contact with both side surfaces of the housing 11 and the rear plate 25 is slidably brought into contact with the rear surface of the housing 11, and the contact piece 27 enters the notch 28. When the shield cover 13 reaches a predetermined depth, the contact piece 27 enters the cavity 17 from the notch 28, and its free end comes into contact with and contacts the rear wall 21b of the bent portion 20b of the outer conductor 20. The piece 27 is elastically deformed. When the shield cover 13 reaches the normal depth, as shown in FIGS. 1 to 3, the lower surface of the front portion of the side plates 24 comes into contact with the upper surface of the substrate fixing portion 16, and the entire area of the contact piece 27 is a cavity. 17 enters into a state of elastic contact with the rear wall 21b.

  After the board shield connector 10 is assembled in this way, the mounting operation to the circuit board B is subsequently performed. When the board shield connector 10 is aligned with a predetermined position on the circuit board B, the board shield connector 10 is attached to the circuit board B from above in the vertical direction. Then, the board connection tabs 18c and 22 in the electrical connector 12 and the board fixing pieces 26 in the shield cover 13 are inserted into the corresponding through holes of the circuit board B, respectively. Thereafter, the board connection tabs 18c and 22 and the board fixing pieces 26 are fixed to the circuit board B by soldering, and bolts are inserted into the circuit board B from the lower side of the circuit board B (not shown). The board shield connector 10 is fixed to the circuit board B in an attached state by being tightened to the bolt holes 16 a of the board fixing portion 16.

  In this attached state, the inner conductor 18 connected to the signal circuit conductive path of the circuit board B is surrounded by the outer conductor 20 connected to the ground circuit conductive path of the circuit board B via the dielectric 19, and Further, it is double shielded by being surrounded by a shield cover 13 connected to the ground circuit conductive path of the circuit board B through the housing 11. In addition, since the shield cover 13 and the outer conductor 20 are directly electrically connected by the contact piece 27, higher shielding performance is obtained.

  As described above, according to the present embodiment, the board shield connector 10 is mounted on the circuit board B, the housing 11 is mounted on the housing 11, the inner conductor 18, and the dielectric 19 surrounding the inner conductor 18. And an outer conductor 20 that surrounds the dielectric 19, a shield cover 13 that is attached to the housing 11 and that surrounds the electrical connector 12, and is provided on the shield cover 13 and contacts the outer conductor 20. Possible contact piece 27.

  In this way, the inner conductor 18 is double-shielded and shielded by the outer conductor 20 and the shield cover 13, so that high shielding performance can be obtained. Moreover, since the outer conductor 20 and the shield cover 13 are directly connected by the contact piece 27, higher shielding performance can be obtained. Furthermore, since the contact piece 27 is provided on the shield cover 13 side, if the contact piece is provided on the electrical connector side, the electrical connector is compared with a dedicated product with a contact piece. Since a general-purpose product can be used as 12, the cost can be reduced.

  The outer conductor 20 includes a straight portion 20a extending along the plate surface of the circuit board B and a bent portion 20b bent with respect to the straight portion 20a, while the housing 11 accommodates the electric connector 12 therein. The cavity 17 is provided so as to open in a direction along the plate surface of the circuit board B, and the contact piece 27 is in contact with the bent portion 20b. In this way, the contact piece 27 can be arranged using the cavity 17. Therefore, if the contact piece is brought into contact with the straight portion, it is necessary to form at least a portion surrounding the straight portion 20a as compared with the need to form a notch for passing the contact piece in the portion surrounding the straight portion of the peripheral wall of the cavity. There is no need to form such a notch, which is effective in maintaining the protective function of the electrical connector 12.

  Moreover, the contact piece 27 is formed in the shape of a spring. If it does in this way, the contact stability with respect to the electrical connector 12 of the shield cover 13 can be improved, and shield performance can be exhibited stably.

  As shown in FIGS. 7 and 8, the shield cover 13A is mounted along the front-rear direction (the direction along the plate surface of the circuit board B) with respect to the housing 11A. This coincides with the insertion direction of the electrical connector 12A with respect to 11A (the axial direction of the cavity 17A). As described in the first embodiment, the contact piece 27A is arranged at the rear end position in the cavity 17A in the mounted state (FIG. 9). Accordingly, the space in the cavity 17A can be used as a passage path for the contact piece 27A in the process of mounting the shield cover 13A. Thereby, in the housing 11A according to the present embodiment, as shown in FIG. 12, a dedicated cutout (see reference numeral 28 in FIG. 4) for passing the contact piece as in the first embodiment communicates with the cavity 17A. Therefore, the peripheral wall of the cavity 17A is secured over its entire length.

The holding portion 30 is formed with a holding groove 30a that allows the holding piece 29 to enter the rear, and the above-described biting protrusion 29a bites into the edge of the groove so that the shield cover for the housing 11A is formed. 13A can be held.

  An operation of mounting the shield cover 13A having the above-described configuration on the housing 11A will be described. In the state shown in FIGS. 7 and 8, the shield cover 13A is attached to the housing 11A from the rear along the front-rear direction. Then, the both side plates 24A and the upper plate 23A are slidably contacted with the peripheral surface of the housing 11A, and when the predetermined depth is reached, both holding pieces 29 are inserted into the holding grooves 30a of both holding portions 30 and the biting projections 29a are formed. It bites into the groove edge of the holding groove 30a.

When the shield cover 13A reaches the normal depth, as shown in FIGS. 9 and 10, the contact piece 27A that has entered the cavity 17A is brought into elastic contact with the rear wall 21bA of the outer conductor 20A and the shield. The front surfaces of both side plates 24A of the cover 13A are brought into contact with the rear surfaces of both holding portions 30.

  As described above, according to the present embodiment, the mounting direction of the shield cover 13A with respect to the housing 11A is oriented along the plate surface of the circuit board B. In this way, the cavity 17A can be used as an entry path of the contact piece 27A with respect to the housing 11A when the shield cover 13A is attached. Accordingly, when the mounting direction of the shield cover with respect to the housing is perpendicular to the plate surface of the circuit board as in the first embodiment, it is necessary to form a notch communicating with the cavity in the housing in order to pass the contact piece during the mounting process. Compared with the case, such a notch is not formed in the housing 11A, and the protection function of the electrical connector 12A can be sufficiently obtained.
