[0003] [Patent Document 1] JP 2013-222684 A [Patent Document 2] Japanese Utility Model Application Publication No. 5-59773 Summary of the Invention [Problem to be solved by the invention]

[0004] When the shield terminal is assembled from above into the housing groove, it is desirable to provide the shield terminal with a locking portion for the housing. For example, a locking portion protruding laterally from the barrel portion of the shield terminal can be fitted into the recess of the housing. However, when multiple shield terminals are arranged side by side in the housing, if the above-mentioned configuration is adopted, the recess will be located between the housing grooves of adjacent shield terminals, making it impossible to narrow the pitch of the housing grooves, resulting in a problem of the connector becoming larger.

[0005] Therefore, an object of the present disclosure is to provide a shield terminal and a connector that can prevent the connector from becoming large. [Means for solving the problem]

[0006] The shielded terminal of the present disclosure is a shielded terminal that is assembled to a housing from one direction that intersects the front-to-rear direction, and has an outer conductor that forms an outer shell, and the outer conductor has a locking portion that protrudes in the one direction from a surface facing the one direction and is positioned so as to be able to engage with the housing. Effect of the Invention

[0007] According to the present disclosure, it is possible to provide a shield terminal that can prevent the connector from becoming large. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] [Description of the embodiments of the present disclosure] First, the embodiments of the present disclosure will be listed and described. The shield terminal of the present disclosure comprises: (1) A shielded terminal that is assembled to a housing from one direction intersecting the front-to-rear direction, the terminal having an outer conductor that forms an outer shell, the outer conductor having a locking portion that protrudes in the one direction from a surface facing the one direction and is positioned so as to be able to be engaged with the housing.

[0010] Since the locking portion is shaped to protrude in one direction from a surface facing in one direction, which is the assembly direction of the shield terminal, it is possible to prevent the connector from becoming large in the width direction intersecting with the assembly direction of the shield terminal.

[0011] (2) It is preferable that the outer conductor has a main body portion connected to a mating outer conductor, a barrel portion connected to an electric wire rearward of the main body portion, and a base portion located between the barrel portion and the main body portion, and that the locking portion has a shape obtained by bending a part of the base portion.

[0012] The barrel portion is usually bent by crimping so as to fit the outer circumference of the electric wire. Therefore, if the locking portion is provided on the barrel portion, it is difficult to ensure the positional accuracy and dimensional accuracy of the locking portion. In this respect, according to the above-mentioned configuration, the locking portion is provided on a part of the base portion located between the barrel portion and the main body portion, so that it is easy to ensure the positional accuracy and dimensional accuracy of the locking portion. In addition, the degree of freedom in molding the locking portion can be increased.

[0013] (3) The main body portion may be shaped to extend in the one direction and may have an opposing surface facing rearward so as to face the locking portion.

[0014] Since the locking portion can be contained within the formation range of the main body portion without independently protruding in one direction of the shield terminal, 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 may be in the form of a plate with the plate surface facing in the fore-and-aft direction, and a reinforcing portion that is hammered forward may be formed at the base portion on the front side of the locking portion.

[0016] When the electric wire is pulled backward, for example, the rear surface of the locking portion (the rear surface of the locking portion) is pressed strongly against the corresponding surface of the housing, which may cause plastic deformation of the locking portion. In this regard, according to the above configuration, a reinforcing portion is formed at the base portion on the front side of the locking portion, which makes it possible to prevent the locking portion from plastically deforming.

[0017] (5) A connector comprising the shielded terminal described in (3) above and the housing, wherein the housing has a locking receiving portion that locks the locking portion and an insertion portion into which the main body portion is inserted, forward of the locking receiving portion, and the insertion portion and the locking receiving portion are preferably arranged side by side in the fore-and-aft direction.

[0018] According to the above configuration, when the electric wire is pulled backward with the shield terminal accommodated in the housing, the force caused by the pulling can be received by the locking portion between the locking receiving portion and the locking portion, thereby restricting the retreat of the main body portion and preventing the main body portion from interfering with the inner surface of the insertion portion of the housing and being deformed.

[0019] [Details of the embodiment of the present disclosure] Specific examples of the present disclosure will be described below with reference to the drawings. Note that the present invention is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope of the claims.

[0020] <Embodiment 1> As shown in Fig. 1, the connector 10 according to the first embodiment of the present disclosure includes a housing 20 and a shield terminal 30. The shield terminal 30 is accommodated in the housing 20 in a state where it is assembled to an end portion of an electric wire 90. In the following description, the front-rear direction corresponds to the length direction of the electric wire 90, and the side where the electric wire 90 is routed as viewed from the shield terminal 30 is defined as the rear side. In the up-down direction, the side where the shield terminal 30 is assembled to the housing 20 is defined as the upper side. This up-down direction does not indicate the positional relationship or direction when actually mounted on a device 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> 1, the housing 20 is made of synthetic resin and has an accommodation groove 21 extending in the front-rear direction and an insertion portion 22 extending downward from the front end of the accommodation groove 21. The accommodation groove 21 is open upward over its entire length in the front-rear direction. A covering member 23 such as a cover or a separate housing is attached to the housing 20 from above to close the upper surface of the accommodation groove 21.

[0022] A concave lock receiving portion 24 is formed on the lower surface of the accommodating groove 21 of the housing 20. The lock receiving portion 24 is disposed in close proximity to the rear of the insertion portion 22 at a position toward the front end of the accommodating groove 21.

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

[0024] <Shield terminal> As shown in FIG. 1, the shield terminal 30 has an inner conductor 31, outer conductors 32 and 33 surrounding the outer periphery of the inner conductor 31, and a dielectric 34 disposed between the inner conductor 31 and the outer conductors 32 and 33. The inner conductor 31, the outer conductors 32 and 33, and the dielectric 34 are all L-shaped in a 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 between the outer conductors 32 and 33 and the inner conductor 31. The inner conductor 31 is crimped and conductively connected to the core 91 of the electric wire 90 at the rear end of the portion extending in the front-rear direction, and is conductively connected to a mating inner conductor of a mating terminal (not shown) at the lower end of the portion extending in the up-down direction.

[0025] As shown in FIG. 2, the outer conductors 32, 33 form the outer shell of the shield terminal 30, and are made up 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 Figs. 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 each other in the front-rear direction. The barrel portion 35 has a pair of left and right front barrel pieces 38 (only one is shown in Figs. 2 and 3) rising from the front end portion of the bottom portion 37, a pair of left and right intermediate barrel pieces 39 (only one is shown in Figs. 2 and 3) rising from the front-rear intermediate portion of the bottom portion 37, and a pair of left and right rear barrel pieces 41 (only one is shown in Figs. 2 and 3) rising from the rear end portion of the bottom portion 37.

[0027] The barrel portion 35 is connected to the electric wire 90 by crimping, and is bent into a shape having a circular cross section or a shape close to a circular cross section as a whole while curving the bottom portion 37. The diameter of the portion corresponding to each of the intermediate barrel pieces 39 is made smaller than the diameter of the portions corresponding to each of the front barrel pieces 38 and each of the rear barrel pieces 41.

[0028] The base 36 has a plate-like portion 42 that is flat in the front-rear and left-right directions at a position lower than the bottom 37. The locking portion 43 is formed by bending the plate-like portion 42 at its center. Specifically, a square U-shaped cut is made in the center of the plate-like portion 42, and the plate piece portion in the cut is bent downward from the front end to form the locking portion 43. The locking portion 43 has a rectangular plate shape and is arranged in the up-down direction with the plate surface facing forward and backward. The locking portion 43 has a triangular pyramid-shaped reinforcing portion 44 formed at its base. The reinforcing portion 44 is shaped such that the portion extending from the base of the locking portion 43 to the front end side of the plate-like portion 42 is hammered forward.

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

[0030] A rising main body portion 46 having a rectangular shape in side view is formed one step higher on the front end side of each rising portion 45. The upper end of the rising main body portion 46 serves as a fastened portion 47 that can come into contact with a fastening portion 61 (described later) of the second outer conductor 33. The fastened portion 47 of the rising main body portion 46 is disposed along the front-rear direction.

[0031] The second outer conductor 33 is formed by bending a metal plate or the like. As shown in Figs. 2 and 4, the second outer conductor 33 has a cylindrical main body 48 and a plate-shaped extending portion 49. The extending portion 49 has a lower extending portion 51 that is connected to the main body 48 at a right angle, and an upper extending portion 53 that is connected to the main body 48 via a hinge 52 so as to be openable and closable between an open state (the state shown in Fig. 4) and a closed state (the state shown in Figs. 1, 2, and 5). In the open state, the extending portion 49 is arranged upright on the main body 48, and the upper opening of the main body 48 is opened. In the closed state, the extending portion 49 is arranged in the front-rear direction, and the upper opening of the main body 48 is closed by an extending base end portion 59 described later.

[0032] The main body 48 is electrically connected to a mating outer conductor of a mating terminal (not shown) in a state where it is inserted into the insertion portion 22 of the housing 20. A resilient contact portion 54 (see FIG. 2) capable of contacting a mating outer conductor arranged inside the main body 48 is formed on the lower end side of the main body 48. The main body 48 has an opposing surface 65 facing rearward so as to face the locking portion 43.

[0033] As shown in FIG. 4, a pair of plate-shaped left and right engagement pieces 55 are formed on the upper end side of the main body 48, and an open portion 56 that is open to the rear is formed between the rear ends of the engagement pieces 55. The lower extension portion 51 is in the form of a plate extending rearward from the lower end of the open portion 56 of the main body 48. The rear end portion of the lower extension portion 51 is formed narrower than the front end portion of the lower extension portion 51. The upper extension portion 53 has a plate-shaped main extension portion 57 that is connected to the front upper end portion of the main body 48 via a hinge 52, and a pair of sub-extension portions 58 that are bent at right angles from the left and right ends of the main extension portion 57.

[0034] As shown in FIG. 2, the main extension portion 57 is disposed so as to extend in the front-rear direction in the closed state. An extension base end portion 59 that closes the upper opening of the main body portion 48 in the closed state is formed at a position near the hinge 52 of the main extension portion 57. In the closed state, the extension base end portion 59 is located in front of each of the sub-extension portions 58 and is disposed along the front-rear direction and the left-right direction. As shown in FIG. 4 and FIG. 5, a pair of left and right stop portions 61 that protrude laterally are formed on the extension base end portion 59. Each stop portion 61 has a rectangular plate shape and protrudes laterally above the open portion 56 and beyond the outer periphery of the main body portion 48 in the closed state. The sideward protruding dimension of the stop portion 61 is the same as the plate thickness dimension of the rising main body portion 46, which is also the width dimension of the stopped portion 47, or is larger than the plate thickness dimension of the rising main body portion 46.

[0035] In the closed state, the auxiliary extension portion 58 has a pair of connecting ends 62 protruding downward from the left and right ends of the main extension portion 57, and a pair of divided portions 63 extending rearward from each connecting end 62. In the closed state, the rear end of the main extension portion 57, the rear end of the lower extension portion 51, and each divided portion 63 have a circular or nearly circular shape as a whole in a rear view, and are disposed along the outer periphery of the shield portion 93 of the electric wire 90. As shown in FIG. 2, in a state in which the first outer conductor 32 and the second outer conductor 33 are assembled, the rear end of the lower extension portion 51 is covered by the bottom portion 37 of the first outer conductor 32, and the rear ends of the main extension portion 57 and each divided portion 63 are covered by each front barrel piece 38 of the first outer conductor 32. In this manner, 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] <Shield terminal assembly method and assembly structure> The second outer conductor 33 is in an open state (the state shown in FIG. 4), and the dielectric 34 is inserted from above into the main body 48. The inner conductor 31, which is connected to the core 91 of the electric wire 90 in advance, is accommodated in the dielectric 34. However, if the dielectric 34 has a lid portion 64 (see FIG. 1), the inner conductor 31 may be inserted into the dielectric 34 after the dielectric 34 is inserted into the main body 48, and the lid portion 64 may be closed.

[0037] Next, the second outer conductor 33 is brought into the closed state. In the closed state, as shown in Fig. 1, the main extension 57 of the second outer conductor 33 is arranged so as to be able to come into contact with the upper surface of the dielectric 34. In addition, in the closed state, as shown in Fig. 2, a gap G1 is formed in the up-down direction between the rear end of the engagement piece 55 and the front end of the connecting end 62, and a gap G2 is formed in the front-rear direction between the auxiliary 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 arranged 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 to perform crimping. The front barrel pieces 38, the middle barrel pieces 39 and the rear barrel pieces 41 are each bent and crimped to connect to the end portion of the electric wire 90. Specifically, the front barrel pieces 38 are conductively connected to the shield portion 93 of the electric wire 90 with the rear end of the extension 49 sandwiched therebetween. The middle barrel pieces 39 are directly crimped to the shield portion 93 of the electric wire 90 and conductively connected. The rear barrel pieces 41 are mechanically connected to the sheath 94 of the electric wire 90. In the first embodiment, the crimping processes for the front barrel pieces 38, the intermediate barrel pieces 39, and the rear barrel pieces 41 may be performed simultaneously or separately with an interval between each other.

[0039] When the first outer conductor 32 and the second outer conductor 33 are assembled, as shown in FIG. 2, each raised portion 45 of the first outer conductor 32 is arranged to overlap the outer surface side of the extension portion 49, blocking gaps G1, G2 formed in the second outer conductor 33.

[0040] 2 and 5, each fastening portion 61 of the second outer conductor 33 is disposed opposite to and in contact with a fastened portion 47 of each rising main body portion 46 along the front-rear direction. As shown in Fig. 2, the locking portion 43 is disposed opposite to and spaced apart from the rear of the main body portion 48.

[0041] <Shield terminal housing structure> 1, when the shielded terminal 30 is accommodated in the housing 20, the main body portion 48 is inserted into the insertion portion 22 of the housing 20, and the plate-shaped portion 42 of the first outer conductor 32 is disposed along the lower surface of the accommodation 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 shielded terminal 30 can enter the locking receiving portion 24 of the housing 20 as the shielded terminal 30 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 disposed opposite to and in contact with the inner surface of the locking receiving portion 24 in the up-down direction.

[0042] When the shielded terminal 30 is accommodated in the housing 20, for example, when the electric wire 90 is pulled backward and a force F (see FIG. 1) acts to pull the shielded terminal 30 backward, the rear surface of the locking portion 43 strongly contacts the inner surface of the locking receiving portion 24 to receive the force F. This restricts the retreat of the shielded terminal 30. In addition, because the retreat of the main body portion 48 is also restricted, it is possible to prevent 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 being deformed. Since the locking portion 43 has the reinforcing portion 44 formed therein, it is possible to prevent the locking portion 43 from being plastically deformed even if the rear surface of the locking portion 43 strongly contacts the inner surface of the locking receiving portion 24.

[0043] However, when a force F is applied to the first outer conductor 32, the first outer conductor 32 may tilt in a direction (upward direction UR, see Figs. 1 and 2) rotating about an engaging portion between the engaging portion 43 and the engaging portion 24 (a portion where the rear surface of the engaging portion 43 contacts the inner surface of the engaging portion 24), and the first outer conductor 32 may be displaced in the upward direction UR relative to the second outer conductor 33. However, in the first embodiment, each of the fastening portions 61 of the first outer conductor 32 contacts each of the fastened portions 47 of the second outer conductor 33 in a displacement direction in the upward direction UR, so that the first outer conductor 32 can be prevented from being displaced in the upward direction UR relative to the second outer conductor 33. As a result, the first outer conductor 32 and the second outer conductor 33 can be maintained in a properly assembled state.

[0044] As described above, according to the first embodiment, the following effects can be achieved. 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 prevent the shield terminal 30 from becoming large in the width direction. Also, in the housing 20, the lock-receiving portion 24 that receives the locking portion 43 is formed on the lower surface of the accommodating groove 21 and is contained within the groove width of the accommodating groove 21. Therefore, it is also possible to prevent the connector 10 from becoming large in the width direction.

[0045] In addition, since the locking portion 43 is formed by cutting out a portion of the base 36 located between the barrel portion 35 and the main body portion 48, it is easier to ensure the positional accuracy and dimensional accuracy of the locking portion 43, and further, the freedom in molding the locking portion 43 can be increased.

[0046] Moreover, since both the main body 48 and the locking portion 43 are formed to extend in the vertical direction and the opposing surface 65 of the main body 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. Furthermore, since the rib-shaped reinforcing portion 44 is formed at the base portion on the front side of the locking portion 43, it is possible to prevent the locking portion 43 from being plastically deformed.

[0047] Furthermore, according to the first embodiment, the following effects can be achieved. If the wire 90 is pulled backward, for example, and the first outer conductor 32 attempts to shift in position relative to the second outer conductor 33 in the upward direction UR around the engaging portion between the engaging portion 43 and the engaging receiving portion 24, the engaged portions 47 of each rising main body portion 46 of the first outer conductor 32 can come into contact with each engaging portion 61 of the second outer conductor 33, thereby preventing the second outer conductor 33 from shifting in position relative to the first outer conductor 32.

[0048] Furthermore, when the electric wire 90 is pulled backward, the force F resulting from the pulling can be received by the locking portion between the lock-receiving portion 24 and the locking portion 43. This restricts the retreat of the main body portion 48, and prevents the main body portion 48 from interfering with the inner surface of the insertion portion 22 of the housing 20 and becoming deformed.

[0049] Moreover, since the fastened portion 47 is formed at the upper end of the rising main body portion 46, there is no need to perform special processing for forming the fastened portion 47 on the first outer conductor 32. Furthermore, the rising portion 45 closes the gap in the first outer conductor 32, thereby making it possible to prevent noise from leaking out or entering.

[0050] [Another embodiment of the present disclosure] The first embodiment disclosed herein should be considered as illustrative in all respects and not restrictive. In the first embodiment, the locking portion is formed at the base of the first outer conductor. However, in other embodiments, the locking portion may be formed at a portion of the first outer conductor other than the base, for example, at a barrel portion, as long as the locking portion does not protrude outward in the width direction of the first outer conductor. In the first embodiment, the locking portion is formed by cutting and raising a part of the base. However, in other embodiments, the locking portion may be formed by bending a protruding portion of the base. In the first embodiment, the main body is formed to extend in the up-down 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, the base, the bottom, etc. In the first embodiment, the outer conductor is composed of a first outer conductor and a second outer conductor which are separate from each other. However, in other embodiments, the outer conductor may be a single, entirely integrated member. [Explanation of symbols]
