Shielded connector

Abstract

The object of the present invention is to stabilize the relative positional relationship between the outer conductor and the inner conductor. The shielded connector (S) comprises: a dielectric body (30) made of synthetic resin; an inner conductor (21) fixedly attached to a circuit board (P) in an integrated state with the dielectric body (30); and an outer conductor (40) fixedly attached to the circuit board (P) surrounding the dielectric body (30), wherein a first protrusion (61) and a second protrusion (62) are formed on the dielectric body (30) in a plastically deformed state abutting against the outer conductor (40). Because the inner conductor (21) and the dielectric body (30) are integrated relative to the outer conductor (40) through the plastically deformed first protrusion (61) and second protrusion (62), relative displacement between the inner conductor (21) and the outer conductor (40) can be suppressed.

Detailed Implementation

[0009] [Description of Embodiments of the Invention] First, embodiments of the present invention will be described. Embodiments obtained by arbitrarily combining the following multiple embodiments within a scope that does not produce contradictions are also included in the specific embodiments of the present invention.

[0010] (1) The shielded connector of the present invention comprises: a dielectric body made of synthetic resin; an inner conductor fixedly to a circuit board in an integral state with the dielectric body; and an outer conductor fixedly to the circuit board in a state surrounding the dielectric body, wherein a protrusion is formed in the dielectric body that abuts against the outer conductor in a plastically deformed state. According to the structure of the present invention, since the inner conductor and the dielectric body are integrated with the outer conductor through the plastically deformed protrusion, the relative positional relationship between the outer conductor and the inner conductor is stable.

[0011] (2) In (1), preferably, the outer surface of the dielectric includes a positioning surface and a wobbling-eliminating surface, the positioning surface and the wobbling-eliminating surface being located in the middle sandwiching the inner conductor and facing opposite directions. Preferably, the positioning surface is in surface contact with the outer conductor, and the protrusion is formed on the wobbling-eliminating surface. According to this structure, by making the positioning surface of the dielectric in surface contact with the outer conductor, the posture of the dielectric and the inner conductor relative to the outer conductor is stabilized. Thus, when the shielded connector is subjected to vibration, etc., changes in the posture of the dielectric and the inner conductor relative to the outer conductor can be suppressed.

[0012] (3) In (2), preferably, the sway-eliminating surface has an opening for receiving the inner conductor, and the protrusion is formed on both sides of a pair of non-opening regions in the sway-eliminating surface that sandwich the protrusion. According to this structure, the dielectric is more stable in posture relative to the outer conductor than if the protrusion is formed only in the non-opening region of one of the pair of non-opening regions.

[0013] (4) In (3), preferably, the opening of the indentation hole in the sway-eliminating surface is formed as an elongated slit, and in the pair of non-opening regions, a plurality of the protrusions are spaced apart along the length of the opening. According to this structure, compared to a configuration where the protrusions are formed in only one location in each non-opening region, the dielectric and inner conductor are equivalent to an outer conductor with stable posture.

[0014] (5) In (4), preferably, the non-opening region is formed in a shape that extends elongatedly along the opening, and the two protrusions are disposed at both ends in the length direction of the non-opening region. According to this structure, the attitude of the dielectric relative to the outer conductor can be stabilized compared to the method in which the protrusions are formed only in areas other than the two ends of the non-opening region.

[0015] (6) In (5), preferably, the protrusion forms an elongated rib extending along the opening. According to this structure, within a limited area outside the opening region, a wider contact area between the protrusion and the outer conductor can be ensured, thus effectively suppressing misalignment between the dielectric and the outer conductor.

[0016] (7) In (2) to (6), preferably, the dielectric has: a first receiving portion having the positioning surface and the wobbling-eliminating surface, with its length direction oriented in a direction intersecting the circuit board; and a second receiving portion protruding from the positioning surface at an end of the first receiving portion opposite to the circuit board. Preferably, the protrusion is disposed at both ends of the first receiving portion in the wobbling-eliminating surface in the length direction of the first receiving portion. According to this structure, in the length direction of the first receiving portion, the protrusion is disposed at both the same position as the second receiving portion and at a different position from the second receiving portion. Thus, not only can the posture of the first receiving portion relative to the outer conductor be stabilized, but the posture of the second receiving portion relative to the outer conductor can also be stabilized.

[0017] (8) In (7), preferably, the outer conductor is formed by combining a first shell surrounding the first receiving portion and a second shell surrounding the second receiving portion, and the protrusion includes a first protrusion abutting against the first shell and a second protrusion abutting against the second shell. According to this structure, a dielectric abuts against both the first and second shells by means of the first and second protrusions. According to this structure, compared to a method where the protrusion abuts only against either the first or second shell, the contact range of the protrusion relative to the outer conductor becomes wider, thus stabilizing the posture of the dielectric relative to the outer conductor.

[0018] [Detailed Description of Embodiments of the Invention] [Example 1] Reference Figures 1 to 8The shielded connector S of Embodiment 1, which embodies the present invention, is described below. The invention is not limited to these illustrations, but is shown by the claims, including all modifications within the meaning and scope equivalent to the claims. In this Embodiment 1, regarding the front-to-back direction, Figures 1-3 In equations 5-8, direction F is defined as forward. Regarding the up and down directions, ... Figures 1-6 The H direction is defined as upward. Regarding the left and right directions, Figures 1-4 In 7 and 8, the R direction is defined as the right.

[0019] In this embodiment 1, the shielded connector S is mounted on the circuit board P (see reference). Figures 4-6 The mounting surface M of the shielded connector S is assembled and engages with the opposite connector (not shown) mounted on the terminal portion of the wire harness (not shown). The shielded connector S is constructed by assembling the housing 10 and the shielded terminal 20. A terminal storage chamber 11 for housing the shielded terminal 20 is formed inside the housing 10. The terminal storage chamber 11 is open on the rear and lower surfaces of the housing 10.

[0020] The shielding terminal 20 is constructed by assembling an inner conductor 21, a dielectric 30, and an outer conductor 40. When viewed from the side, the inner conductor 21 is a single component bent into an L-shape. The inner conductor 21 has a substrate connection portion 22 that is elongated in the vertical direction and a terminal connection portion 23 extending forward from the upper end of the substrate connection portion 22. The lower end of the substrate connection portion 22 is connected to the circuit board P. The terminal connection portion 23 is connected to the terminal part (not shown) of the opposite connector.

[0021] Like the inner conductor 21, the dielectric 30 is bent into an L-shape. The dielectric 30 is a single component comprising a first housing portion 31 housing a substrate connection portion 22 and a second housing portion 32 housing a terminal connection portion 23. The first housing portion 31 is formed into an elongated prism shape in the vertical direction. The second housing portion 32 is a cylindrical portion protruding forward from the upper end of the first housing portion 31. The upper end of the first housing portion 31 is formed into an arc shape concentric with the second housing portion 32. A press-in hole 33 for housing the inner conductor 21 is formed inside the dielectric 30. The press-in hole 33 opens on the rear and lower surfaces of the first housing portion 31 and the front end face of the second housing portion 32. The inner conductor 21 is integrated with the dielectric 30 by being pressed into the press-in hole 33 from the rear of the dielectric 30.

[0022] The front surface of the first storage section 31 is composed of a single plane. The front surface of the first storage section 31 is defined as the positioning surface 35. The rear surface of the first storage section 31 is defined as the first wobbling-eliminating surface 36. The opening 34 of the press-in hole 33 in the first wobbling-eliminating surface 36 is formed into a narrow slit in the vertical direction. The regions adjacent to the left and right sides of the opening 34 in the first wobbling-eliminating surface 36 are defined as a pair of symmetrical non-opening regions 37. The non-opening regions 37 are formed into a narrow shape in the vertical direction. The region below the arc-shaped portion concentric with the second storage section 32 on the left and right outer surfaces of the first storage section 31 is defined as the second wobbling-eliminating surface 38.

[0023] The outer conductor 40 is constructed by assembling a first metal shell 41 and a second metal shell 42. The first shell 41 and the second shell 42 are formed by casting, forging, machining, etc. The first shell 41 is a single component having a bottom wall portion 43 and a rear wall portion 44 protruding upwards from the rear end of the bottom wall portion 43. A positioning hole 45 is formed in the bottom wall portion 43, penetrating the bottom wall portion 43 in the front-rear direction. When viewed from above in a top view of the shielded connector S (outer conductor 40), the opening shape of the positioning hole 45 is square. The rear surface of the inner circumferential surface of the positioning hole 45 is coplanar and continuous with respect to the front surface of the rear wall portion 44.

[0024] The second shell 42 is a single component having a box portion 46 and a cylindrical portion 52. The box portion 46 has a front wall portion 47, an upper wall portion 48, and a pair of left and right side wall portions 49. The upper wall portion 48 extends rearward from the upper edge of the front wall portion 47. The pair of side wall portions 49 are perpendicularly connected to the left and right side edges of the front wall portion 47 and the left and right side edges of the upper wall portion 48. The lower end of the side wall portion 49 protrudes downward beyond the lower end of the front wall portion 47. The second shell 42 has multiple (two pairs in this embodiment 1) grounding connection portions 50 for connecting to the grounding circuit (not shown) of the circuit board P. The grounding connection portions 50 protrude downward from the front and rear ends of the lower surface of each side wall portion 49. The cylindrical portion 52 is a portion that protrudes forward from the front wall portion 47 with its axis pointing in the front-rear direction. The internal space of the box portion 46 and the internal space of the cylindrical portion 52 are interconnected. The interior space of the box section 46 is open on the rear and lower surfaces of the box section 46.

[0025] The outer conductor 40 is constructed by assembling the first shell 41 from below to the second shell 42. The first shell 41 and the second shell 42 are integrated by pressing. The pressing locations are, for example, between the left and right outer sides of the rear wall portion 44 and the left and right inner sides of the side wall portion 49, and between the left and right outer sides of the bottom wall portion 43 and the left and right inner sides of the side wall portion 49. With the first shell 41 and the second shell 42 assembled, the bottom wall portion 43 closes the opening on the lower surface of the housing portion 46, and the rear wall portion 44 closes the opening on the rear surface of the housing portion 46. Inside the outer conductor 40, an L-shaped storage space 53 is formed for accommodating the dielectric 30. When the dielectric 30 is not being accommodated, the front end of the storage space 53 opens at the front end face of the cylindrical portion 52. The lower end of the storage space 53 opens at the positioning hole 45 on the lower surface of the bottom wall portion 43.

[0026] When assembling the shielded connector S, firstly, the inner conductor 21 is pressed into the press-in hole 33 from the rear of the dielectric body 30. The dielectric body 30 with the inner conductor 21 pressed in is then housed inside the second housing 42 from the rear. Next, the first housing 41 is assembled to the second housing 42 such that the positioning hole 45 engages with the lower end of the first housing portion 31. When the first housing 41 and the second housing 42 are assembled, the dielectric body 30 is housed within the housing space 53 of the outer conductor 40, forming the outer conductor 40. This completes the assembly of the shielded terminal 20. By housing the assembled shielded terminal 20 inside the housing 10, the assembly of the shielded connector S is completed.

[0027] With the shielded connector S installed on the circuit board P, the grounding connection portion 50 of the outer conductor 40 is inserted into the grounding through hole G of the circuit board P and is conductively fixed to the grounding circuit by soldering (illustration omitted). The substrate connection portion 22 of the inner conductor 21, which protrudes downward from the lower end of the first receiving portion 31, is inserted into the through hole H of the circuit board P and is conductively fixed to the printed circuit of the circuit board P by soldering.

[0028] The lower end of the first receiving portion 31 is fitted into a positioning hole 45 that opens on the bottom surface of the outer conductor 40 (first housing 41). Due to dimensional tolerances between the first receiving portion 31 and the first housing 41, the first receiving portion 31 and the substrate connecting portion 22 may misalign in the rear-forward or left-right direction within the positioning hole 45, or wobble may occur. As a countermeasure, a positioning surface 35, a plurality of first protrusions 61, and a plurality of second protrusions 62 are formed on the dielectric 30 (first receiving portion 31).

[0029] The first protrusion 61 is the portion that is in close contact with the first shell 41 in the outer conductor 40. The first protrusion 61 is disposed at six locations: the upper and lower ends of a pair of non-opening regions 37 (first sway-eliminating surfaces 36) and the lower ends of the two second sway-eliminating surfaces 38 on the left and right. The second protrusion 62 is the portion that is in close contact with the second shell 42 in the outer conductor 40. The second protrusion 62 is disposed at the upper ends of the two second sway-eliminating surfaces 38 on the left and right. The two second protrusions 62 protrude from the second sway-eliminating surfaces 38 in opposite directions in the left-right direction.

[0030] Viewed from above, the outer surfaces of the first protrusion 61 and the second protrusion 62 are arc-shaped. Viewed from the rear of the dielectric body 30 (shielded connector S), the first protrusion 61 is elongated in the vertical direction. Viewed from the side of the dielectric body 30, the first protrusion 61 and the second protrusion 62 are also elongated in the vertical direction. The long side of the first protrusion 61 is parallel to the assembly direction of the dielectric body 30 and the first housing 41.

[0031] With the outer conductor 40 and dielectric 30 assembled, the positioning surface 35 abuts against the inner surface of the outer conductor 40 (receiving space 53) from the rear in a surface contact state. Specifically, the lower end region of the positioning surface 35 is in close contact with the front surface of the inner peripheral surface of the positioning hole 45 from the rear. The upper end region of the positioning surface 35 is in close contact with the rear surface of the front wall portion 47 of the second housing 42 from the rear. Two first protrusions 61 disposed at the lower end of the first wobbling elimination surface 36 (non-opening region 37) are in close contact with the rear surface of the inner peripheral surface of the positioning hole 45 from the front. The first protrusions 61 of the positioning surface 35 and the non-opening region 37 are in close contact with the inner surface of the positioning hole 45 (first housing 41) in the front-rear direction, thereby positioning the lower end of the first receiving portion 31 and the inner conductor 21 relative to the first housing 41 in the front-rear direction.

[0032] With the outer conductor 40 and dielectric 30 assembled, the two first protrusions 61 located at the lower end of the second wobbling-eliminating surface 38 are in close contact with the left and right inner surfaces of the positioning hole 45 in the left-right direction. The two second protrusions 62 located at the upper end of the second wobbling-eliminating surface 38 are in close contact with the inner surfaces of the left and right side walls 49 of the second housing 42 in the left-right direction and from opposite directions. By the close contact between the first protrusions 61 and the second protrusions 62 and the side walls 49, the first receiving portion 31 is positioned relative to the outer conductor 40 in the left-right direction. The two first protrusions 61 located at the upper end of the first wobbling-eliminating surface 36 (non-opening region 37) are in close contact with the front surface of the rear wall 44 of the first housing 41 from the front.

[0033] During the assembly of dielectric 30 and outer conductor 40, the first protrusion 61 and the second protrusion 62 undergo plastic deformation due to interference with the outer conductor 40, thus forming a tight contact with the outer conductor 40 in a pressed state. Through the contact of the positioning surface 35 with the outer conductor 40 and the tight contact of the first protrusion 61 and the second protrusion 62 with the outer conductor 40 in a pressed state, the lower ends of the first receiving portion 31 and the substrate connecting portion 22 are positioned within the positioning hole 45 in a two-dimensional direction (front-back and left-right directions) parallel to the mounting surface M of the circuit board P. Therefore, on the mounting surface M of the circuit board P, the outer conductor 40 and the inner conductor 21 maintain the expected positional relationship.

[0034] The shielded connector S of this embodiment 1 includes a dielectric body 30 made of synthetic resin, an inner conductor 21, and an outer conductor 40. The inner conductor 21 is fixed to the circuit board P in an integrated state with the dielectric body 30. The outer conductor 40 is fixed to the circuit board P in a state that surrounds the dielectric body 30. A first protrusion 61 and a second protrusion 62 are formed on the dielectric body 30, which abut against the outer conductor 40 in a plastically deformed state. According to this structure, since the inner conductor 21 and the dielectric body 30 are integrated with respect to the outer conductor 40 through the plastically deformed first protrusion 61 and second protrusion 62, the relative displacement between the inner conductor 21 and the outer conductor 40 can be suppressed. As a result, the relative positional relationship between the outer conductor 40 and the inner conductor 21 is stable. In addition, when the shielded connector S is subjected to vibration, etc., due to the relative displacement of the inner conductor 21 and the outer conductor 40, stress concentration at the fixed portion of the inner conductor 21 and the circuit board P or the fixed portion of the outer conductor 40 and the circuit board P can be suppressed.

[0035] The outer surface of the dielectric 30 has a positioning surface 35 and a first wobbling-eliminating surface 36. The positioning surface 35 and the first wobbling-eliminating surface 36 are located at the position where the inner conductor 21 is sandwiched in the middle, and face opposite directions in the front-back direction. The positioning surface 35 contacts the first shell 41 and the second shell 42 of the outer conductor 40 in a surface contact state. A first protrusion 61 is formed on the first wobbling-eliminating surface 36. According to this structure, by making the positioning surface 35 of the dielectric 30 in surface contact with the outer conductor 40, the posture of the dielectric 30 and the inner conductor 21 relative to the outer conductor 40 is stabilized. As a result, when the shielded connector S is subjected to vibration, etc., changes in the posture of the dielectric 30 and the inner conductor 21 relative to the outer conductor 40 can be suppressed.

[0036] The first wobbling-eliminating surface 36 has an opening with a press-in hole 33 for receiving the inner conductor 21. A first protrusion 61 is formed on both sides of a pair of non-opening regions 37 that sandwich the opening 34 of the first wobbling-eliminating surface 36 containing the press-in hole 33. According to this structure, the dielectric 30 is more stable in posture relative to the outer conductor 40 compared to a configuration where a protrusion is formed only on one of the pair of non-opening regions 37.

[0037] The opening 34 of the press-in hole 33 in the first wobbling-eliminating surface 36 is formed in the shape of a narrow slit in the vertical direction. In a pair of non-opening regions 37, a plurality of first protrusions 61 are arranged at intervals along the length of the opening 34. According to this structure, compared with a method in which the protrusions are formed in only one location in each non-opening region 37, the attitude of the dielectric 30 and the inner conductor 21 relative to the outer conductor 40 is more stable.

[0038] The non-opening region 37 is formed into a shape that extends elongatedly along the opening 34 in the vertical direction. Two first protrusions 61 are disposed at both ends of the non-opening region 37 in the length direction. According to this structure, compared with the method of forming the protrusions only in the region other than the two ends of the non-opening region 37, the attitude of the dielectric 30 relative to the outer conductor 40 can be stabilized.

[0039] The first protrusion 61 and the second protrusion 62 form slender ribs extending along the opening 34. According to this structure, within a limited area in the non-opening region 37, the contact area between the first protrusion 61 and the outer conductor 40 and the contact area between the second protrusion 62 and the outer conductor 40 can be ensured to be relatively large, thus effectively suppressing misalignment between the dielectric 30 and the outer conductor 40.

[0040] The dielectric 30 has a first receiving portion 31 and a second receiving portion 32. The first receiving portion 31 has a positioning surface 35 and a first wobbling-eliminating surface 36. The first receiving portion 31 is shaped such that its length direction is oriented in a vertical direction intersecting the circuit board P. The second receiving portion 32 is shaped such that it protrudes forward from the positioning surface 35 and from the end of the first receiving portion 31 on the side opposite to the circuit board P. A first protrusion 61 is disposed at both ends of the first receiving portion 31 in the first wobbling-eliminating surface 36 in the length direction of the first receiving portion 31. According to this structure, the first protrusion 61 is disposed at both the same position as the second receiving portion 32 and at a different position from the second receiving portion 32 in the length direction of the first receiving portion 31. As a result, not only can the posture of the first receiving portion 31 relative to the outer conductor 40 be stabilized, but the posture of the second receiving portion 32 relative to the outer conductor 40 can also be stabilized.

[0041] The outer conductor 40 is formed by combining a first shell 41 surrounding the first receiving portion 31 and a second shell 42 surrounding the second receiving portion 32. The protrusions include a first protrusion 61 abutting against the first shell 41 and a second protrusion 62 abutting against the second shell 42. According to this structure, a dielectric 30 abuts against both the first shell 41 and the second shell 42 by means of the first protrusion 61 and the second protrusion 62. According to this structure, compared to a method where the protrusion abuts only against either the first shell 41 or the second shell 42, the contact range of the protrusion relative to the outer conductor 40 becomes wider, thus making the posture of the dielectric 30 relative to the outer conductor 40 more stable.

[0042] [Other Embodiments] This invention is not limited to the embodiments described above and illustrated in the drawings, but is illustrated by the claims. This invention includes all modifications within the meaning and scope of the claims, as well as the embodiments described below. The dielectric may also not have a positioning surface that contacts the outer conductor surface. In this case, a protrusion can be formed on the outer surface that corresponds to the positioning surface. Alternatively, a protrusion may be formed only in either of the two non-opening regions of the shaking-eliminating surface. The protrusions in each non-open area can be formed in only one location or in more than three locations. The protrusions may also be located only in areas other than the ends of the non-opening areas. The shape of the protrusion is not limited to a slender rib with a circular arc cross-section; it can also be a rib with a spherical or triangular cross-section. The protrusion can also be in the form of abutting only against either the first shell or the second shell. The protrusion can be formed on both the first and second storage sections, or it can be formed only on the second storage section. The shape of the indentation hole on the shaking elimination surface is not limited to a slit shape; it can also be a wide rectangle, etc. The inner conductor and dielectric can also be in shapes other than L-shape. The inner conductor can also be integrated with the dielectric through insert molding. In this case, the dielectric can also be in a form without press-in holes, openings, or non-opening regions.
