Description

Technical Field

[0001] The present invention relates to a connector and a connector device. Background Art

[0002] Conventionally, as a connector for suppressing the shaking of terminal parts in a cavity, a connector described in Japanese Patent Laid-Open No. 2001-110500 (hereinafter referred to as Patent Document 1) is known. This connector includes a female-side terminal part, a connector housing, and a holding body mounted at the front end of the connector housing. The connector housing has a cavity for accommodating the female-side terminal part. The connector housing has a lance-shaped part that engages with the terminal part from the rear. The holding body has a pressing contact part that contacts the lower surface of the terminal part and presses the terminal part against the top wall of the cavity. When the terminal part is inserted into the cavity, the terminal part is primarily engaged by the lance-shaped part. When the holding body is assembled to the connector housing, a restricting piece provided on the holding body enters the flexure space of the lance-shaped part, restricting the flexure deformation of the lance-shaped part, so that the terminal part is doubly engaged in a state of preventing detachment. In this state, the terminal part is pressed against the top wall of the cavity by the pressing contact part, so that the shaking of the terminal part in the vertical direction is suppressed.

[0008] [Description of the embodiment of the present invention] First, the embodiments of the present invention will be listed and described. [1] The connector of the present invention includes: a plurality of terminals arranged and configured in a first direction; a housing having a plurality of cavities respectively accommodating the plurality of terminals, the terminals being inserted into the cavities from the rear in a second direction intersecting the first direction; and a holding body mounted on the housing from the front in the second direction, a pair of lance-shaped portions arranged and configured in the first direction being formed on the inner wall of the cavity, the plurality of terminals having at least one elliptical terminal having an elliptical shape in a front view, the elliptical terminal having: a cylindrical portion opening forward and being longer in the first direction; and a pair of locked portions, the elliptical terminal being held by respectively locking the pair of lance-shaped portions to the pair of locked portions, the pair of lance-shaped portions being able to flex in the first direction, the holding body having: a pair of flexure restraining portions respectively restricting the flexure of the pair of lance-shaped portions by entering the flexure spaces of the pair of lance-shaped portions; and a pair of support walls supporting the outer peripheral surface of the cylindrical portion from both sides in the first direction.

[0009] According to such a structure, the cylindrical portion of the elliptical terminal is supported from both sides in the first direction by a pair of support walls, thereby preventing the elliptical terminal from moving in the first direction. Since the pair of support walls are provided on the holding body, regardless of the tolerance for assembling the holding body to the housing, by setting the pair of support walls according to the dimension of the elliptical terminal in the first direction, the sway of the elliptical terminal in the cavity can be suppressed.

[0010] [2] In the above [1], preferably, the elliptical terminal has a terminal portion accommodated in the cylindrical portion and being longer in the second direction, the front end of the terminal portion being located between the front end of the cylindrical portion and the inner wall of the cylindrical portion in the second direction, and the pair of support walls support a portion of the outer peripheral surface of the cylindrical portion that is more forward than the inner wall. By supporting a portion of the outer peripheral surface of the cylindrical portion that is more forward than the inner wall by a pair of support walls, it is easy to suppress the sway of the elliptical terminal in the cavity.

[0011] [3] In the above [1] or [2], preferably, the cylindrical portion has a pair of arcuate surfaces at both ends in the first direction, the support wall has a curved surface formed along the arcuate surface, and the curved surface supports the cylindrical portion from both sides in the first direction in a state of being in contact with the arcuate surface. In this way, the cylindrical portion of the elliptical terminal can be supported from both sides in the first direction in a state where the curved surfaces of the respective support walls are in contact with the arcuate surface of the cylindrical portion.

[0012] [4] In any one of the above [1] to [3], preferably, the holding body can move between a temporary locking position that allows the pair of lance-shaped portions to flex and a formal locking position that suppresses the flexing of the pair of lance-shaped portions. At the temporary locking position, the front ends of the pair of support walls are located in front of the front end of the cylindrical portion. Since the front ends of the pair of support walls are located in front of the front end of the cylindrical portion, it is easy to protect the cylindrical portion from both sides in the first direction at the temporary locking position.

[0013] [5] The connector device of the present invention includes: the connector according to any one of the above [1] to [4]; a mating-side housing that can be fitted to the housing; and a mating-side holding body attached to the mating-side housing. The mating-side holding body has a pair of mating-side support walls. When the housing and the mating-side housing are fitted together, the pair of mating-side support walls and the pair of support walls support the outer peripheral surface of the cylindrical portion from both sides in the first direction. According to such a structure, the cylindrical portion of the elliptical terminal is supported from both sides in the first direction by both the pair of support walls and the pair of mating-side support walls, thereby preventing the elliptical terminal from moving in the first direction.

[0014] [Details of Embodiments of the Present Invention] Hereinafter, embodiments of the present invention will be described. The present invention is not limited to these examples and is shown by the claims, aiming to include all modifications within the meaning and scope equivalent to the claims. In each of the drawings, for convenience of explanation, sometimes a part of the structure is shown enlarged or simplified. Also, the dimensional ratios of the respective parts may be different in each of the drawings. In this specification, "orthogonal" includes not only cases where it is strictly orthogonal but also cases where it is substantially orthogonal within the range where the functions and effects in the present embodiment are achieved.

[0015] In addition, "opposite" in this specification means that surfaces or members are located opposite to each other, and includes not only cases where they are completely opposite to each other but also cases where they are partially opposite to each other. In addition, "opposite" in this specification includes both cases where a member independent of the two parts is interposed between the two parts and cases where nothing is interposed between the two parts.

[0016] <Embodiment> Refer to Figures 1 to 13An embodiment of the present invention will be described. In the following description, the direction indicated by the arrow line Z is taken as the upper direction, the direction indicated by the arrow line X is taken as the front direction, and the direction indicated by the arrow line Y is taken as the left direction for description. The left-right direction is an example of the first direction. The front-back direction is an example of the second direction. The up-down direction is an example of the third direction. In addition, for a plurality of identical members, sometimes only some of the members are labeled with reference numerals, and the reference numerals of other members are omitted.

[0017] (Connector device 100) As Figure 12 shown, the connector device 100 includes a male connector 50 and a female connector 10. The female connector 10 includes a synthetic resin female housing 20, a synthetic resin female holder 30, and a plurality of female terminals 40. As Figure 1 and Figure 4 shown, the male connector 50 includes a synthetic resin male housing 60, a synthetic resin male holder 70, and a plurality of male terminals 80. The female housing 20 corresponds to the "opposite-side housing" of the present invention, and the female holder 30 corresponds to the "opposite-side holder" of the present invention.

[0018] (Male terminal 80) As Figure 2 and Figure 10 shown, the plurality of male terminals 80 have an elliptical terminal 81 and a pair of contact terminals 82. The elliptical terminal 81 has an elliptical shape when viewed from the front, and the pair of contact terminals 82 are located on the left and right sides of the elliptical terminal 81. The elliptical terminal 81 and the pair of contact terminals 82 are arranged and configured in the left-right direction. The male terminal 80 is formed by stamping a metal plate with excellent conductivity. Since the male connector 50 includes a plurality of male terminals 80 (81, 82), it is sometimes also referred to as a hybrid connector.

[0019] As Figure 5 and Figure 6 shown, the elliptical terminal 81 includes a pair of pin terminals 83, a conductive shielding member 84 surrounding the pair of pin terminals 83, and an insulating member 85 insulating between the pair of pin terminals 83 and the shielding member 84. The pin terminal 83 corresponds to the "terminal portion" of the present invention.

[0020] The pair of pin terminals 83 are connected to the terminals of a pair of cables for transmitting differential signals. Since the elliptical terminal 81 is used for a high-speed transmission twisted-pair cable, the male connector 10 is sometimes also referred to as an HMTD (High-Speed Modular Twisted-Pair Data) connector.

[0021] The shielding member 84 has: a front cylindrical portion 84A that is open at the front and is longer in the left-right direction when viewed from the front; a rear cylindrical portion 84B disposed behind the front cylindrical portion 84A; and a front stopper projection 84C that projects upward from the upper surface of the rear cylindrical portion 84B. The front cylindrical portion 84A has a pair of arcuate surfaces 86 formed at both end portions in the left-right direction, and the rear cylindrical portion 84B has a pair of engaged portions 87 formed at the rear end portion. The front stopper projection 84C is a projection for performing front stopping of the elliptical terminal 81 within the male housing 60. The pair of engaged portions 87 are arranged in the left-right direction.

[0022] As Figure 10 and Figure 11 shown, the front end of the insulating member 85 is located behind the front end of the front cylindrical portion 84A. The front end of the pin terminal 83 is located between the front end of the front cylindrical portion 84A and the front end of the insulating member 85 in the front-rear direction. The front end of the insulating member 85 corresponds to the "inner wall of the cylindrical portion" of the present invention.

[0023] The joint terminal 82 includes a flat plate-shaped joint portion and a cylindrical portion disposed behind it. The cylindrical portion has a cylindrical piece, and by tightening and crimping the cylindrical piece to the core wire and the wire covering portion constituting the covered wire, the joint terminal 82 is electrically and mechanically connected to each covered wire.

[0024] (Male housing 60) As Figure 3 and Figure 7 shown, the male housing 60 includes a male housing main body 61 having a substantially square block shape and a male cover portion 62 extending forward from the front peripheral edge of the male housing main body 61. The male cover portion 62 has a square tubular shape and is open at the front. The front surface of the male housing main body 61 is exposed forward through the internal space of the male cover portion 62.

[0025] A plurality of male cavities 63 are formed inside the male housing main body 61, and various male terminals 80 are respectively accommodated in the plurality of male cavities 63. The male cavity 63A for accommodating the elliptical terminal 81 among the plurality of male cavities 63 is located at the central portion of the male housing 60 when viewed from the front. The male terminal 80 is inserted into the male cavity 63A from the rear.

[0026] The male cavity 63A is formed between a pair of upper and lower male terminal receiving walls 64. As Figure 9 shown, the male terminal receiving walls 64 are formed along the upper and lower surfaces of the shielding member 84 of the elliptical terminal 81 and the arcuate surfaces 86 connected to both sides thereof. Therefore, the elliptical terminal 81 is restricted from moving in the up-down direction and is restricted from moving in the left-right direction by the pair of male terminal receiving walls 64.

[0027] As Figure 11As shown, inside the male cavity 63A, a pair of left and right lance-shaped portions 65 arranged in the left-right direction are provided. The lance-shaped portions 65 are in a form that protrudes forward in a cantilever shape from the inner wall constituting the male cavity 63A. The lance-shaped portions 65 are formed to be flexible in the left-right direction. On the opposing surfaces of the pair of lance-shaped portions 65 facing each other, locking portions 65A are respectively formed. By the locking portions 65A of the pair of lance-shaped portions 65 respectively locking to a pair of locked portions 87 of the elliptical terminal 81, the elliptical terminal 81 is held in a state of being prevented from falling off backward.

[0028] On the left and right side surfaces of the outer peripheral surface of the male housing body 61, a pair of holding protrusions 66 are respectively formed. The male holder 70 can move relative to the male housing 60 between a temporary locking position ( Figure 10 the position of the male holder 70 shown) and a formal locking position ( Figure 11 the position of the male holder 70 shown). The male holder 70 is configured to be able to be held in the positions of the temporary locking position and the formal locking position respectively by locking to the pair of holding protrusions 66.

[0029] (male holder 70) As Figure 4 shown, the male holder 70 includes: a male holder body 71, constituting the front surface of the male housing 60; a pair of mounting portions 72, arranged on the left and right sides of the male holder body 71; and a plurality of flexure suppression portions 75, protruding rearward from the rear surface of the male holder body 71. The male holder body 71 has a plurality of terminal insertion holes 73 through which the male terminal 80 is inserted. The male holder 70 is mounted on the male housing 60 from the front. The fitting surface of the male housing 60 is constituted by the male holder body 71 of the male holder 70.

[0030] As Figure 8 shown, on the opposing surfaces of the pair of mounting portions 72 facing each other, mounting protrusions 74 extending in the up-down direction are respectively formed. In the temporary locking position, by the Figure 10 shown holding protrusion 66 locking to the mounting protrusion 74, the state where the backward movement of the male holder 70 is suppressed is achieved. In the formal locking position, by the Figure 11 shown holding protrusion 66 locking to the mounting protrusion 74, the state where the forward movement of the male holder 70 is suppressed is achieved.

[0031] As Figure 8 ​As shown, a pair of flexure suppression portions 75 are formed on the rear surface of the male holding body main body 71. The flexure suppression portions 75 are in a form protruding rearward from the hole edge of the terminal insertion hole 73. The pair of flexure suppression portions 75 are disposed opposite to each other in the left-right direction. Inside the pair of flexure suppression portions 75, a pair of support walls 76 are formed protruding in a direction approaching each other. The support walls 76 are integrally formed with the flexure suppression portions 75. Therefore, the flexure suppression portions 75 are strengthened by the support walls 76. The rear end of the support wall 76 is located forward of the rear end of the flexure suppression portion 75.

[0032] The support wall 76 has a curved surface 76A formed along the arc surface 86 of the elliptical terminal 81. The curved surface 76A contacts the arc surface 86 with substantially the entire surface. As Figure 9 and Figure 11 shown, in the formal locking position, the pair of curved surfaces 76A contact the pair of arc surfaces 86. The curved surface 76A contacts the arc surface 86 in the left-right direction and also in the up-down direction. Therefore, in the formal locking position, the elliptical terminal 81 does not sway in the left-right direction and does not fall downward. Additionally, as Figure 10 shown, in the temporary locking position, the pair of curved surfaces 76A also partially contact the pair of arc surfaces 86. Therefore, in the temporary locking position, the elliptical terminal 81 does not sway in the left-right direction and does not fall downward. In both the temporary locking position and the formal locking position, the elliptical terminal 81 is held in the male housing main body 61 in a state where the arc surface 86 of the front cylindrical portion 84A is supported by the pair of support walls 76 from both sides in the left-right direction. That is, the curved surface 76A supports the front cylindrical portion 84A from both sides in the left-right direction in a state of contacting the arc surface 86.

[0033] In both the temporary locking position and the formal locking position, the pair of support walls 76 support a portion of the outer peripheral surface of the front cylindrical portion 84A that is forward of the front end of the insulating member 85. In the temporary locking position, the front ends of the pair of support walls 76 are located forward of the front end of the front cylindrical portion 84A.

[0034] In the temporary locking position, the pair of flexure suppression portions 75 are in a state of retreating from the flexure space of the pair of lance portions 65, thus allowing the pair of lance portions 65 to flex. On the other hand, in the formal locking position, the pair of flexure suppression portions 75 are in a state of entering the flexure space of the pair of lance portions 65, thus suppressing the flexure of the pair of lance portions 65. Therefore, in the formal locking position, the elliptical terminal 81 is double-locked by the pair of lance portions 65 and the pair of flexure suppression portions 75.

[0035] Figure 12Shows the normal fitting state of the male housing 60 and the female housing 20. In this state, the elliptical terminal 81 of the male connector 50 and the female terminal 40 of the female connector 10 are electrically connected. As described above, the female connector 10 is formed with the same structure as the male connector 50. That is, the female connector 10 includes a female housing 20 that can be fitted with the male housing 60 and a female holding body 30 mounted on the female housing 20. The female holding body 30 includes a female holding body main body 31, a pair of support walls 32, and a pair of flexure suppression portions 33. The pair of support walls 32 support the outer peripheral surface of the female terminal 40 from both sides in the left-right direction and also support the outer peripheral surface of the front-side cylindrical portion 84A of the elliptical terminal 81 from both sides in the left-right direction. The female housing 20 corresponds to the "opposite-side housing" of the present invention, the female holding body 30 corresponds to the "opposite-side holding body" of the present invention, and the support wall 32 corresponds to the "opposite-side support wall" of the present invention.

[0036] A terminal insertion port 34 for inserting the male terminal 80 from the front is formed in the female holding body main body 31 of the female holding body 30. The pair of support walls 76 are inserted into the terminal insertion port 34 together with the male terminal 80. The flexure suppression portion 33 enters the flexure space of the lance-shaped portion 21 provided inside the female housing 20.

[0037] As Figure 13 shown, the front-side cylindrical portion 84A of the elliptical terminal 81 is supported by both the pair of support walls 76 of the male holding body 70 and the pair of support walls 32 of the female holding body 30 from both sides in the left-right direction. As Figure 11 shown, a part of the front-side cylindrical portion 84A protrudes more forward than the front ends of the pair of support walls 76, but the protruding portion is supported by the pair of support walls 32 of the female holding body 30. In particular, the vicinity of the contact portion where the pin terminal 83 of the elliptical terminal 81 is connected to the female terminal 40 is supported by the support walls 32 and 76 of the male and female holding bodies 30 and 70, so that wear of the contact portion can be easily suppressed.

[0038] (Function and effect of the embodiment) (1) The male connector 50 of the embodiment has: a plurality of male terminals 80 arranged in the left - right direction; a male housing 60 having a plurality of male cavities 63 for respectively accommodating the plurality of male terminals 80, and the male terminals 80 are inserted into the male cavities 63 from the rear in the front - rear direction intersecting the left - right direction; and a male holder 70 mounted on the male housing 60 from the front in the front - rear direction. A pair of lance - shaped portions 65 arranged in the left - right direction are formed on the inner wall of the male cavity 63. The plurality of male terminals 80 have at least one elliptical terminal 81 whose front view is elliptical. The elliptical terminal 81 has: a front - side cylindrical portion 84A that is open at the front and is longer in the left - right direction; and a pair of engaged portions 87. The elliptical terminal 81 is held by being respectively engaged with the pair of engaged portions 87 by the pair of lance - shaped portions 65. The pair of lance - shaped portions 65 can be flexed in the left - right direction. The male holder 70 has: a pair of flexure - suppressing portions 75 that respectively limit the flexure of the pair of lance - shaped portions 65 by entering the flexure spaces of the pair of lance - shaped portions 65; and a pair of support walls 76 that support the outer peripheral surface of the front - side cylindrical portion 84A from both sides in the left - right direction.

[0039] According to such a structure, the front - side cylindrical portion 84A of the elliptical terminal 81 is supported from both sides in the left - right direction by the pair of support walls 76, thereby preventing the elliptical terminal 81 from moving in the left - right direction. Since the pair of support walls 76 are provided on the male holder 70, regardless of the tolerance for assembling the male holder 70 to the male housing 60, by setting the pair of support walls 76 according to the left - right dimension of the elliptical terminal 81, the sway of the elliptical terminal 81 in the male cavity 63A can be suppressed.

[0040] (2) The elliptical terminal 81 has a pin terminal 83 accommodated in the front - side cylindrical portion 84A and is longer in the front - rear direction. The front end of the pin terminal 83 is located between the front end of the front - side cylindrical portion 84A and the front end of the insulating member 85 in the front - rear direction. The pair of support walls 76 support a portion of the outer peripheral surface of the front - side cylindrical portion 84A that is in front of the front end of the insulating member 85. By supporting, by the pair of support walls 76, a portion of the outer peripheral surface of the front - side cylindrical portion 84A that is in front of the front end of the insulating member 85, it is easy to suppress the sway of the elliptical terminal 81 in the male cavity 63A.

[0041] (3) The front - side cylindrical portion 84A has a pair of arcuate surfaces 86 at both ends in the left - right direction. The support wall 76 has a curved surface 76A formed along the arcuate surface 86, and the curved surface 76A supports the front - side cylindrical portion 84A from both sides in the left - right direction in a state of being in contact with the arcuate surface 86. In this way, the front - side cylindrical portion 84A of the elliptical terminal 81 can be supported from both sides in the left - right direction in a state where the curved surface 76A of each support wall 76 is in contact with the arcuate surface 86 of the front - side cylindrical portion 84A.

[0042] (4) The male holding body 70 can move between a temporary locking position that allows the pair of lance portions 65 to flex and a formal locking position that suppresses the flexure of the pair of lance portions 65. At the temporary locking position, the front ends of the pair of support walls 76 are located in front of the front end of the front cylindrical portion 84A. Since the front ends of the pair of support walls 76 are located in front of the front end of the front cylindrical portion 84A, it is easy to protect the front cylindrical portion 84A from both sides in the left - right direction at the temporary locking position.

[0043] (5) The connector device 100 of the present invention further includes a male connector 50, a female housing 20 that can be fitted with the male housing 60, and a female holding body 30 mounted on the female housing 20. The female holding body 30 has a pair of support walls 32. When the male housing 60 and the female housing 20 are fitted together, the pair of support walls 32 and the pair of support walls 76 support the outer peripheral surface of the front cylindrical portion 84A from both sides in the left - right direction. According to such a structure, by the pair of support walls 76 and the pair of support walls 32 both supporting the front cylindrical portion 84A of the elliptical terminal 81 from both sides in the left - right direction, the elliptical terminal 81 is prevented from moving in the left - right direction.

[0045] · In the above - described embodiment, the elliptical terminal 81 is supported by the pair of support walls 76 at both the temporary locking position and the formal locking position.
