Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, when the shield terminal is assembled and housed in the housing groove of the housing from above, it is desirable to provide a locking portion for the shield terminal with respect to the housing. For example, a locking portion having a shape protruding laterally from the barrel portion may be provided on the shield terminal, and a configuration in which this locking portion is fitted into the recess of the housing may be adopted. However, when a plurality of shield terminals are arranged side by side with respect to the housing, if the above configuration is adopted, a recess will be located between the housing grooves of adjacent shield terminals, so that the narrow pitch of each housing groove cannot be achieved, and the problem that the connector becomes large-sized occurs.

[0005] Therefore, the present disclosure aims to provide a shielded terminal and connector that can avoid increasing the size of the connector. [Means for solving the problem]

[0006] The shield terminal of this disclosure is a shield terminal that is assembled to a housing from one direction intersecting the front-rear direction, and comprises an outer conductor that constitutes an outer shell, the outer conductor having a locking portion that protrudes from the surface facing the one direction in the one direction and is arranged to be lockable to the housing. [Effects of the Invention]

[0007] According to this disclosure, it is possible to provide a shielded terminal that avoids increasing the size of the connector. [Brief explanation of the drawing]

[0008] [Figure 1] Figure 1 is a cross-sectional view showing the state in which the shield terminal is housed in the housing in Embodiment 1 of the present disclosure. [Figure 2] Figure 2 is a side view of the shield terminal. [Figure 3] Figure 3 is a perspective view of the first outer conductor. [Figure 4] Figure 4 is a perspective view of the second outer conductor in the open state. [Figure 5] Figure 5 is a plan view of the front end of the shield terminal. [Modes for carrying out the invention]

[0009] [Description of Embodiments in this Disclosure] First, the embodiments of this disclosure will be listed and described. The shield terminals in this disclosure are (1) A shield terminal that is assembled to the housing from one direction intersecting the front-rear direction, comprising an outer conductor that constitutes the outer shell, the outer conductor having a locking portion that protrudes from the surface facing the one direction in the one direction and is arranged to be lockable to the housing.

[0010] Because the locking portion protrudes in one direction from a surface facing the same direction as the assembly direction of the shield terminal, it is possible to avoid increasing the size of the connector in the width direction that intersects the assembly direction of the shield terminal.

[0011] (2) The outer conductor has a main body portion connected to the other outer conductor, a barrel portion connected to the electric wire behind the main body portion, and a base portion located between the barrel portion and the main body portion, and the locking portion is preferably shaped by bending a part of the base portion.

[0012] The barrel portion is typically bent to conform to the outer circumference of the electric wire by crimping. Therefore, if the locking portion is provided on the barrel portion, ensuring positional and dimensional accuracy of the locking portion becomes difficult. However, with the above configuration, since the locking portion is provided on a part of the base located between the barrel portion and the main body portion, it becomes easier to ensure positional and dimensional accuracy of the locking portion. Furthermore, the degree of freedom in shaping the locking portion can be increased.

[0013] (3) The main body portion is preferably shaped to extend in one direction and has an opposing surface facing backward so as to face the locking portion.

[0014] Since the locking portion does not independently protrude in one direction from the shield terminal but is contained within the formation range of the main body, it is possible to avoid the shield terminal becoming larger in one direction due to the presence of the locking portion.

[0015] (4) The locking portion is in the shape of a plate, with its plate surface facing the front-to-back direction, and it is preferable that a reinforcing portion is formed at the base of the front side of the locking portion in a shape that is hammered out forward.

[0016] When the electric wire is pulled backward or the like, there is a concern that the rear surface of the locking portion (the rear side surface of the locking portion) is strongly pressed against the corresponding surface of the housing, causing the locking portion to plastically deform. In this regard, according to the above configuration, since the reinforcing portion is formed at the root portion on the front surface side of the locking portion, it is possible to avoid the situation where the locking portion plastically deforms.

[0017] (5) A connector including the shield terminal described in (3) above and the housing, wherein the housing has a locking receiving portion for locking the locking portion and an insertion portion into which the main body portion is inserted in front of the locking receiving portion, and it is preferable that the insertion portion and the locking receiving portion are arranged side by side in the front-rear direction.

[0018] According to the above configuration, when the electric wire is pulled backward in a state where the shield terminal is housed in the housing, the force caused by the pulling can be received at the locking portion between the locking receiving portion and the locking portion. As a result, the backward movement of the main body portion is restricted, and it is possible to avoid the situation where the main body portion interferes with the inner surface of the insertion portion of the housing and is deformed.

[0019] [Details of Embodiments of the Present Disclosure] Specific examples of the present disclosure will be described below with reference to the drawings. It should be noted that the present invention is not limited to this exemplification, and is shown by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.

[0020] [Embodiment 1] The connector 10 according to Embodiment 1 of this disclosure comprises a housing 20 and a shield terminal 30, as shown in Figure 1. The shield terminal 30 is housed in the housing 20 with the end portion of the electric wire 90 attached. In the following description, the front-rear direction corresponds to the length direction of the electric wire 90, and the side on which the electric wire 90 is routed, as seen from the shield terminal 30, is defined as the rear. In the up-down direction, the side on which the shield terminal 30 is attached to the housing 20 is defined as the upper. This up-down direction does not indicate the positional relationship or direction when actually mounted on equipment such as an automobile. In each figure, "F", "R", "U", and "D" indicate "front side", "rear side", "upper side", and "lower side", respectively.

[0021] <Housing> The housing 20 is made of synthetic resin and, as shown in Figure 1, has a housing groove 21 extending in the front-rear direction and an insertion portion 22 extending downward from the front end of the housing groove 21. The housing groove 21 is open upward along its entire length in the front-rear direction. A covering member 23, such as a cover or another housing, is attached to the housing 20 from above to close the upper surface of the housing groove 21.

[0022] A concave locking receiver portion 24 is formed on the lower surface of the housing groove 21 of the housing 20. The locking receiver portion 24 is located near the front end of the housing groove 21 and close to the rear of the insertion portion 22.

[0023] <Electric wire> As shown in Figure 1, the electric wire 90 is a shielded electric wire (coaxial electric wire) and has a core wire 91, insulating coating 92, shield portion 93, and sheath 94 extending from the central axis outward. At the front end of the electric wire 90, the sheath 94 and insulating coating 92 are cut away, and the core wire 91 and shield portion 93 are sequentially exposed. The shield portion 93 is made of braided wire or the like and is connected to an earth portion (not shown).

[0024] <Shield terminal> As shown in Figure 1, the shield terminal 30 has an inner conductor 31, outer conductors 32 and 33 surrounding the outer circumference of the inner conductor 31, and a dielectric 34 positioned between the inner conductor 31 and the outer conductors 32 and 33. The inner conductor 31, outer conductors 32 and 33, and dielectric 34 are all L-shaped in side view, corresponding to the overall shape of the shield terminal 30. The outer conductors 32 and 33 and the inner conductor 31 are made of conductive metal, and the dielectric 34 is made of synthetic resin. The dielectric 34 electrically insulates the outer conductors 32 and 33 from the inner conductor 31. The inner conductor 31 is crimped to the core wire 91 of the electric wire 90 at the rear end of the portion extending in the front-rear direction and electrically connected to the mating inner conductor of a mating terminal (not shown) at the lower end of the portion extending in the vertical direction.

[0025] As shown in Figure 2, the outer conductors 32 and 33 constitute the outer shell of the shield terminal 30 and consist of a first outer conductor 32 and a second outer conductor 33 that are assembled and connected to each other.

[0026] The first outer conductor 32 is formed by bending a metal plate or the like. The first outer conductor 32 has a barrel portion 35 and a base portion 36 extending forward from the barrel portion 35. As shown in Figures 2 and 3, the barrel portion 35 has a bottom portion 37 extending in the front-rear direction. The bottom portion 37 and the base portion 36 are provided continuously with respect to each other in the front-rear direction. The barrel portion 35 has a pair of left and right front barrel pieces 38 (only one shown in Figures 2 and 3) rising from the front end of the bottom portion 37, a pair of left and right intermediate barrel pieces 39 (only one shown in Figures 2 and 3) rising from the front-rear middle portion of the bottom portion 37, and a pair of left and right rear barrel pieces 41 (only one shown in Figures 2 and 3) rising from the rear end of the bottom portion 37.

[0027] The barrel section 35 is crimped and connected to the electric wire 90, and the bottom section 37 is curved while the overall shape is bent into a circular or nearly circular cross-section. The diameter of the portion corresponding to each intermediate barrel piece 39 is smaller than the diameter of the portion corresponding to each front barrel piece 38 and each rear barrel piece 41.

[0028] The base portion 36 has a flat plate-like portion 42 in the front-to-back and left-to-right directions, located at a lower position than the bottom portion 37. A locking portion 43 is formed in the center of the plate-like portion 42 by bending it. Specifically, a U-shaped notch is made in the center of the plate-like portion 42, and the plate piece within the notch is bent downward from the front end to form the locking portion 43. The locking portion 43 is rectangular in shape and is arranged along the vertical direction with the plate surface facing front-to-back. A triangular pyramidal reinforcing portion 44 is formed at the base of the locking portion 43. The reinforcing portion 44 has a shape in which the portion extending from the base of the locking portion 43 to the front end of the plate-like portion 42 is hammered forward.

[0029] The first outer conductor 32 has a pair of rising sections 45 that rise from the left and right ends of the base 36. Each rising section 45 is formed in a plate shape along the vertical direction. The rear end of each rising section 45 is connected to each front barrel piece 38.

[0030] At the front end of each rising section 45, a raised main section 46, which is rectangular in side view, is formed at a higher level. The upper end of the main section 46 is a retaining section 47 that can contact the retaining section 61 of the second outer conductor 33, which will be described later. The retaining section 47 of the main section 46 is arranged along the front-rear direction.

[0031] The second outer conductor 33 is formed by bending a metal plate or the like. As shown in Figures 2 and 4, the second outer conductor 33 has a cylindrical main body portion 48 and a plate-shaped extension portion 49. The extension portion 49 has a lower extension portion 51 that is connected perpendicular to the main body portion 48 and an upper extension portion 53 that is connected to the main body portion 48 via a hinge 52 so as to be able to open and close between an open state (shown in Figure 4) and a closed state (shown in Figures 1, 2, and 5). In the open state, the extension portion 49 is positioned upright on the main body portion 48, and the top opening of the main body portion 48 is opened. In the closed state, the extension portion 49 is positioned in the front-rear direction, and the top opening of the main body portion 48 is closed by an extension base portion 59, which will be described later.

[0032] The main body portion 48 is electrically connected to the mating outer conductor of a mating terminal (not shown) while inserted into the insertion portion 22 of the housing 20. An elastic contact portion 54 (see Figure 2) is formed on the lower end side of the main body portion 48, which can contact the mating outer conductor located inside the main body portion 48. The main body portion 48 has a rearward-facing surface 65 that faces the locking portion 43.

[0033] As shown in Figure 4, a pair of plate-shaped engaging pieces 55 are formed on the upper end of the main body 48, and an open section 56 that opens to the rear is formed between the rear ends of each engaging piece 55. The lower extension 51 is plate-shaped and extends rearward from the lower end of the open section 56 of the main body 48. The rear end of the lower extension 51 is formed to be narrower than the front end of the lower extension 51. The upper extension 53 has a plate-shaped main extension 57 connected to the front of the upper end of the main body 48 via a hinge 52, and a pair of sub-extensions 58 bent at right angles from the left and right ends of the main extension 57.

[0034] As shown in Figure 2, the main extension 57 is positioned to extend in the front-rear direction when closed. Near the hinge 52 of the main extension 57, an extension base end 59 is formed that closes the upper opening of the main body 48 when closed. When closed, the extension base end 59 is located in front of each sub-extension 58 and is positioned along the front-rear and left-right directions. As shown in Figures 4 and 5, a pair of left and right stopper portions 61 are formed on the extension base end 59, which protrude laterally. Each stopper portion 61 is rectangular in shape and protrudes above the opening 56 and laterally beyond the outer circumference of the main body 48 when closed. The lateral projection dimension of the stopper portion 61 is the same as or greater than the plate thickness dimension of the rising main body 46, which is also the width dimension of the stopped portion 47.

[0035] In the closed state, the secondary extension 58 has a pair of connecting ends 62 that protrude downward from the left and right ends of the main extension 57, and a pair of divided parts 63 that extend rearward from each connecting end 62. In the closed state, the rear end of the main extension 57, the rear end of the lower extension 51, and each divided part 63 have a circular or nearly circular shape when viewed from the rear, and are arranged along the outer circumference of the shield portion 93 of the electric wire 90. As shown in Figure 2, when the first outer conductor 32 and the second outer conductor 33 are assembled, the rear end of the lower extension 51 is covered by the bottom 37 of the first outer conductor 32, and the respective rear ends of the main extension 57 and each divided part 63 are covered by the front barrel pieces 38 of the first outer conductor 32. In this way, the main extension portion 57, the lower extension portion 51, and each divided portion 63 are covered and held by the barrel portion 35, thereby maintaining the assembled state of the first outer conductor 32 and the second outer conductor 33.

[0036] <Method and structure of assembly of shield terminals> The second outer conductor 33 is in an open state (as shown in Figure 4), and the dielectric 34 is inserted into the main body 48 from above. The dielectric 34 already contains an inner conductor 31 that is connected to the core wire 91 of the electric wire 90. However, if the dielectric 34 has a cover portion 64 (see Figure 1), the inner conductor 31 may be inserted into the dielectric 34 after the dielectric 34 has been inserted into the main body 48, and the cover portion 64 may be closed.

[0037] Next, the second outer conductor 33 is closed. In the closed state, as shown in Figure 1, the main extension 57 of the second outer conductor 33 is positioned to be in contact with the upper surface of the dielectric 34. Also, in the closed state, as shown in Figure 2, a gap G1 is formed in the vertical direction between the rear end of the engaging piece 55 and the front end of the connecting end 62, and a gap G2 is formed in the front-rear direction between the secondary extension 58 and the lower extension 51.

[0038] Next, the first outer conductor 32 is assembled to the second outer conductor 33 from below. The bottom 37 and base 36 of the first outer conductor 32 are positioned along the lower surface of the lower extension 51 of the second outer conductor 33. In this state, a crimping jig (anvil and crimper) is applied to the barrel portion 35 and crimping is performed. Each front barrel piece 38, each intermediate barrel piece 39, and each rear barrel piece 41 are bent and crimped to the end of the electric wire 90. Specifically, each front barrel piece 38 is electrically connected to the shield portion 93 of the electric wire 90 with the rear end of the extension portion 49 in between. Each intermediate barrel piece 39 is electrically connected by directly crimping to the shield portion 93 of the electric wire 90. Each rear barrel piece 41 is mechanically connected to the sheath 94 of the electric wire 90. In this embodiment 1, the crimping of each front barrel piece 38, each intermediate barrel piece 39, and each rear barrel piece 41 may be performed simultaneously or separately with a time interval between them.

[0039] With the first outer conductor 32 and the second outer conductor 33 assembled, as shown in Figure 2, each rising portion 45 of the first outer conductor 32 is positioned to overlap the outer surface of the extension portion 49, closing the gaps G1 and G2 formed in the second outer conductor 33.

[0040] Furthermore, as shown in Figures 2 and 5, each fastening portion 61 of the second outer conductor 33 is positioned opposite to the fastened portion 47 of each rising body portion 46 so as to contact it along the front-rear direction. As shown in Figure 2, the locking portion 43 is positioned opposite to the rear of the body portion 48 with a gap between them.

[0041] <Housing structure for shield terminals> When the shield terminal 30 is housed in the housing 20, as shown in Figure 1, the main body portion 48 is fitted into the insertion portion 22 of the housing 20, and the plate-shaped portion 42 of the first outer conductor 32 is positioned along the lower surface of the housing groove 21 of the housing 20. Since the locking portion 43 protrudes downward from the plate-shaped portion 42 of the first outer conductor 32, the shield terminal 30 can enter the locking receiving portion 24 of the housing 20 as it descends during the assembly process. When the locking portion 43 enters the locking receiving portion 24, the rear surface of the locking portion 43 (the rear surface of the locking portion 43) is positioned opposite the inner surface of the locking receiving portion 24 so as to contact it in the vertical direction.

[0042] With the shield terminal 30 housed within the housing 20, if a force F (see Figure 1) acts to pull the shield terminal 30 backward, for example, by pulling the electric wire 90 backward, the rear surface of the locking portion 43 strongly contacts the inner surface of the locking receiving portion 24 to absorb the force F. This restricts the backward movement of the shield terminal 30. Furthermore, the backward movement of the main body portion 48 is also restricted, thus preventing the opposing surface 65 of the main body portion 48 from being pressed against the inner surface of the insertion portion 22 of the housing 20 and deforming. Since a reinforcing portion 44 is formed on the locking portion 43, even if the rear surface of the locking portion 43 strongly contacts the inner surface of the locking receiving portion 24, plastic deformation of the locking portion 43 can be avoided.

[0043] However, when a force F acts on the first outer conductor 32, there is a concern that the first outer conductor 32 may tilt in a direction of rotation around the locking portion between the locking portion 43 and the locking receiving portion 24 (the portion where the rear surface of the locking portion 43 contacts the inner surface of the locking receiving portion 24) (upward UR, see Figures 1 and 2), causing the first outer conductor 32 to shift upward UR relative to the second outer conductor 33. However, in this embodiment 1, since each stopper portion 61 of the first outer conductor 32 contacts each stopper portion 47 of the second outer conductor 33 in the direction of displacement upward UR, it is possible to prevent the first outer conductor 32 from shifting upward UR relative to the second outer conductor 33. As a result, it is possible to maintain a state in which the first outer conductor 32 and the second outer conductor 33 are properly assembled.

[0044] As described above, the following effects can be achieved according to this embodiment 1. Since the locking portion 43 is formed to protrude downward from the lower surface of the base portion 36 of the first outer conductor 32, it is possible to avoid increasing the width of the shield terminal 30. Furthermore, in the housing 20, the locking receiving portion 24 that receives the locking portion 43 is formed on the lower surface of the housing groove 21 and fits within the groove width of the housing groove 21. Therefore, it is also possible to avoid increasing the width of the connector 10.

[0045] Furthermore, since the locking portion 43 is formed by cutting and bending a part of the base portion 36 located between the barrel portion 35 and the main body portion 48, it becomes easier to ensure the positional accuracy and dimensional accuracy of the locking portion 43, and it is also possible to increase the degree of freedom in molding the locking portion 43.

[0046] Furthermore, since both the main body portion 48 and the locking portion 43 are formed to extend in the vertical direction, and the opposing surface 65 of the main body portion 48 faces the locking portion 43, the locking portion 43 does not independently protrude below the shield terminal 30. Therefore, the shield terminal 30 does not become larger in the vertical direction due to the presence of the locking portion 43. In addition, since a rib-shaped reinforcing portion 44 is formed at the base of the front side of the locking portion 43, it is possible to avoid the locking portion 43 undergoing plastic deformation.

[0047] Furthermore, according to this embodiment 1, the following effects can be achieved. If the electric wire 90 is pulled backward or otherwise, and the first outer conductor 32 is about to shift upward UR relative to the second outer conductor 33 around the locking portion between the locking portion 43 and the locking receiving portion 24, the secured portions 47 of each rising body portion 46 of the first outer conductor 32 can come into contact with each securing portion 61 of the second outer conductor 33, thereby preventing the second outer conductor 33 from shifting relative to the first outer conductor 32.

[0048] Furthermore, when the electric wire 90 is pulled backward, the force F caused by the pulling can be absorbed by the locking portion between the locking receiving portion 24 and the locking portion 43. This restricts the backward movement of the main body portion 48, preventing the main body portion 48 from interfering with the inner surface of the insertion portion 22 of the housing 20 and deforming.

[0049] Furthermore, since the clamping portion 47 is formed at the upper end of the rising body portion 46, there is no need to perform any special processing on the first outer conductor 32 to form the clamping portion 47. In addition, the rising portion 45 seals the gap in the first outer conductor 32, thereby preventing noise leakage and intrusion.

[0050] [Other embodiments of this disclosure] Embodiment 1 disclosed herein should be considered in all respects to be illustrative and not restrictive. In Embodiment 1, the locking portion was formed at the base of the first outer conductor. However, in other embodiments, the locking portion may be formed in a part of the first outer conductor other than the base, for example, the barrel portion, as long as it does not protrude outward in the width direction of the first outer conductor. In Embodiment 1, the locking portion was formed by cutting and bending a part of the base. However, in other embodiments, the locking portion may be formed by bending a protruding portion of the base. In Embodiment 1, the main body was formed to extend in the vertical direction. However, in other embodiments, the main body may be formed to extend in the front-rear direction so as to be continuous with the extension, base, and bottom. In Embodiment 1, the outer conductor was composed of a first outer conductor and a second outer conductor, which were separate entities. However, in other embodiments, the outer conductor may be a single, integrated component. [Explanation of Symbols]
