Description

Technical Field

[0001] The present disclosure relates to a connector and a connector device.

Background Art

[0002] Conventionally, as a connector that suppresses rattling of a terminal fitting in a cavity, a connector described in Japanese Patent Application Laid-Open No. 2001-110500 (Patent Document 1 below) is known. This connector includes a female terminal fitting, a connector housing having a cavity in which the female terminal fitting is accommodated, and a retainer attached to the front end of the connector housing. The connector housing has a lance that locks the terminal fitting from behind. The retainer has a narrow-pressure contact portion that abuts against the lower surface of the terminal fitting and presses the terminal fitting against the ceiling wall of the cavity. When the terminal fitting is inserted into the cavity, the terminal fitting is primarily locked by the lance, and when the retainer is attached to the connector housing, a regulating piece provided on the retainer enters the deflection space of the lance, and the deflection deformation of the lance is restricted, so that the terminal fitting is doubly locked in a non-removable state. In this state, since the terminal fitting is pressed against the ceiling wall of the cavity by the narrow-pressure contact portion, rattling of the terminal fitting in the vertical direction is suppressed.

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, the connector housing and the retainer are separate components, and a tolerance for assembling them is required, so rattling corresponding to this tolerance has to be tolerated. Therefore, even if a narrow-pressure contact portion is provided on the retainer, it is difficult to suppress rattling of the terminal fitting in the vertical direction.

Means for Solving the Problem

[0005] The connector of the present disclosure has a plurality of types of terminals arranged side by side in a first direction, a plurality of cavities for accommodating the plurality of types of terminals respectively, a housing into which the terminals are inserted into the cavities from the rear in a second direction intersecting the first direction, and a retainer attached to the housing from the front in the second direction. On the inner wall of the cavity, a pair of lances arranged side by side in the first direction are formed. The plurality of types of terminals have at least one elliptical terminal having an elliptical shape when viewed from the front. The elliptical terminal has a cylindrical portion that opens forward and is long in the first direction, and a pair of locked portions that hold the elliptical terminal by locking the pair of lances respectively. The pair of lances are bendable in the first direction, and the retainer has a pair of bending suppression portions that respectively enter the bending spaces of the pair of lances to suppress the bending of the pair of lances, and a pair of support walls that support the outer peripheral surface of the cylindrical portion from both sides in the first direction. It is a connector.

Mode for Carrying Out the Invention

[0008] [Description of Embodiments of the Present Disclosure] First, embodiments of the present disclosure will be listed and described. [1] The connector of the present disclosure has a plurality of types of terminals arranged side by side in a first direction, a plurality of cavities respectively accommodating the plurality of types of terminals, a housing into which the terminals are inserted into the cavities from the rear in a second direction intersecting the first direction, and a retainer attached to the housing from the front in the second direction. A pair of lances arranged side by side in the first direction are formed on the inner wall of the cavity. The plurality of types of terminals have at least one elliptical terminal having an elliptical shape when viewed from the front. The elliptical terminal has a cylindrical portion that opens forward and is long in the first direction, and a pair of locked portions that hold the elliptical terminal by locking the pair of lances respectively. The pair of lances are bendable in the first direction, and the retainer has a pair of bending suppressing portions that respectively enter the bending spaces of the pair of lances to suppress the bending of the pair of lances, and a pair of support walls that support the outer peripheral surface of the cylindrical portion from both sides in the first direction.

[0009] With such a configuration, a pair of support walls support the cylindrical portion of the elliptical terminal from both sides in the first direction, thereby preventing the elliptical terminal from moving in the first direction. Since the pair of support walls are provided on the retainer, regardless of the tolerance for assembling the retainer to the housing, by providing the pair of support walls according to the dimension of the elliptical terminal in the first direction, rattling of the elliptical terminal within the cavity can be suppressed.

[0010] [2] In the above [1], the elliptical terminal has a terminal portion that is housed in the cylindrical portion and is long in the second direction. The front end of the terminal portion is located between the front end of the cylindrical portion and the back wall of the cylindrical portion in the second direction. It is preferable that the pair of support walls support a portion of the outer peripheral surface of the cylindrical portion that is in front of the back wall. By supporting a portion of the outer peripheral surface of the cylindrical portion that is in front of the back wall with a pair of support walls, it becomes easier to suppress rattling of the elliptical terminal within the cavity.

[0011] [3] In the above [1] or [2], the cylindrical portion has a pair of arcuate surfaces located at both ends in the first direction. The support wall has a curved surface formed along the arcuate surface. It is preferable that the curved surface supports the cylindrical portion from both sides in the first direction while being in contact with the arcuate surface. In this way, with the curved surface of each support wall in contact with the arcuate surface of the cylindrical portion, the cylindrical portion of the elliptical terminal can be supported from both sides in the first direction.

[0012] [4] In any of the above [1] to [3], the retainer is movable between a temporary locking position that allows deflection of the pair of lances and a main locking position that suppresses deflection of the pair of lances. In the temporary locking position, it is preferable that 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 in the temporary locking position.

[0013] [5] The connector device of the present disclosure further includes the connector according to any one of [1] to [4] above, a mating housing that can be fitted to the housing, and a mating retainer that is attached to the mating housing. The mating retainer has a pair of mating support walls that support the outer peripheral surface of the cylindrical portion from both sides in the first direction together with the pair of support walls when the housing and the mating housing are fitted together. According to such a configuration, both the pair of support walls and the pair of mating support walls support the cylindrical portion of the elliptical terminal from both sides in the first direction, thereby preventing the elliptical terminal from moving in the first direction.

[0014] [Details of Embodiments of the Present Disclosure] Hereinafter, embodiments of the present disclosure will be described. The present disclosure is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims. In each drawing, for convenience of explanation, a part of the configuration may be exaggerated or simplified. Also, the dimensional ratios of the respective parts may be different in each drawing. In this specification, "orthogonal" includes not only the case of strict orthogonality but also the case of approximate orthogonality within the range where the actions and effects in the present embodiment are exhibited.

[0015] Also, in this specification, "opposite" means that surfaces or members are in a front-to-front position with respect to each other, and includes not only the case where they are completely in a front-to-front position but also the case where they are partially in a front-to-front position. Also, in this specification, "opposite" includes both the case where a member different from the two parts is interposed between the two parts and the case where nothing is interposed between the two parts.

[0016] [Embodiment] Embodiments of the present disclosure will be described with reference to FIGS. 1 to 13. In the following description, the direction indicated by the arrow Z is the upward direction, the direction indicated by the arrow X is the forward direction, and the direction indicated by the arrow Y is the leftward direction. 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. Note that for a plurality of identical members, only some members may be labeled with reference numerals, and the reference numerals of other members may be omitted.

[0017] (Connector device 100) As shown in FIG. 12, the connector device 100 includes a male connector 50 and a female connector 10. The female connector 10 includes a female housing 20 made of synthetic resin, a female retainer 30 made of synthetic resin, and a plurality of types of female terminals 40. The male connector 50 includes a male housing 60 made of synthetic resin, a male retainer 70 made of synthetic resin, and a plurality of types of male terminals 80, as shown in FIGS. 1 and 4. The female housing 20 corresponds to the "counterpart housing" of the present disclosure, and the female retainer 30 corresponds to the "counterpart retainer" of the present disclosure.

[0018] (Male terminal 80) As shown in FIGS. 2 and 10, the plurality of types of male terminals 80 include one elliptical terminal 81 having an elliptical shape in a front view and a pair of tab terminals 82 located on both the left and right sides of the elliptical terminal 81. The elliptical terminal 81 and the pair of tab terminals 82 are arranged side by side in the left-right direction. The male terminal 80 is formed by pressing a metal plate having excellent conductivity. Since the male connector 50 includes a plurality of types of male terminals 80 (81, 82), it may also be referred to as a hybrid connector.

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

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

[0021] The shield member 84 has a front cylindrical portion 84A that opens forward and is long in the left-right direction when viewed from the front, a rear cylindrical portion 84B arranged behind the front cylindrical portion 84A, and a front stop protrusion 84C that protrudes 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 ends in the left-right direction and a pair of engaged portions 87 formed at the rear end of the rear cylindrical portion 84B. The front stop protrusion 84C is a protrusion for performing a front stop within the male housing 60 of the elliptical terminal 81. The pair of engaged portions 87 are arranged side by side in the left-right direction.

[0022] As shown in FIGS. 10 and 11, 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 disclosure.

[0023] The tab terminal 82 includes a tab portion having a flat plate shape and a barrel portion arranged behind it. The barrel portion has a barrel piece, and by caulking and crimping the barrel piece to the core wire and the wire coating that constitute the covered wire, the tab terminal 82 is electrically and mechanically connected to each covered wire.

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

[0025] Inside the male housing body 61, a plurality of male cavities 63 for accommodating a plurality of types of male terminals 80 are formed. Among the plurality of male cavities 63, the male cavity 63A for accommodating the elliptical terminal 81 is located at the center of the male housing 60 in a front view. 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 housing walls 64. As shown in FIG. 9, the male terminal housing walls 64 are formed along the upper and lower surfaces of the shield member 84 of the elliptical terminal 81 and the arcuate surfaces 86 continuous with both sides thereof. Therefore, the elliptical terminal 81 is suppressed from moving in the vertical direction and in the left - right direction by the pair of male terminal housing walls 64.

[0027] Inside the male cavity 63A, as shown in FIG. 11, a pair of left - and - right lance 65 arranged side by side in the left - right direction are provided. The lance 65 is in a cantilevered form protruding forward from the inner wall constituting the male cavity 63A. The lance 65 is formed to be bendable in the left - right direction. Locking portions 65A are respectively formed on the opposing surfaces of the pair of lances 65 facing each other. By the locking portions 65A of the pair of lances 65 respectively locking to the pair of locked portions 87 of the elliptical terminal 81, the elliptical terminal 81 is held in a state of being prevented from coming 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 retainer 70 is movable between a temporary locking position (the position of the male retainer 70 shown in FIG. 10) and a main locking position (the position of the male retainer 70 shown in FIG. 11) with respect to the male housing 60. The male retainer 70 is configured to be held at each of the temporary locking position and the main locking position by locking to the pair of holding protrusions 66.

[0029] (Male retainer 70) As shown in FIG. 4, the male retainer 70 includes a male retainer body 71 that constitutes the front surface of the male housing 60, a pair of mounting portions 72 arranged on both the left and right sides of the male retainer body 71, and a plurality of deflection suppressing portions 75 that project rearward from the rear surface of the male retainer body 71. The male retainer body 71 has a plurality of terminal insertion holes 73 through which the male terminals 80 are inserted. The male retainer 70 is mounted on the male housing 60 from the front. The fitting surface of the male housing 60 is constituted by the male retainer body 71 of the male retainer 70.

[0030] As shown in FIG. 8, mounting protrusions 74 extending in the vertical direction are respectively formed on the opposing surfaces of the pair of mounting portions 72 that face each other. At the temporary locking position, as shown in FIG. 10, the holding protrusion 66 locks to the mounting protrusion 74, thereby suppressing the rearward movement of the male retainer 70. At the main locking position, as shown in FIG. 11, the holding protrusion 66 locks to the mounting protrusion 74, thereby suppressing the forward movement of the male retainer 70.

[0031] As shown in FIG. 8, a pair of deflection suppressing portions 75 are formed on the rear surface of the male retainer body 71. The deflection suppressing portions 75 are configured to project rearward from the hole edge of the terminal insertion hole 73. The pair of deflection suppressing portions 75 are arranged to face each other in the left-right direction. Inside the pair of deflection suppressing portions 75, a pair of support walls 76 are formed to project in a direction approaching each other. The support walls 76 are formed integrally with the deflection suppressing portions 75. Therefore, the deflection suppressing portions 75 are reinforced by the support walls 76. The rear end of the support wall 76 is located in front of the rear end of the deflection suppressing portion 75.

[0032] The support wall 76 has a curved surface 76A formed along the arcuate surface 86 of the elliptical terminal 81. The curved surface 76A is in contact with the arcuate surface 86 almost entirely. As shown in FIGS. 9 and 11, the pair of curved surfaces 76A are adapted to contact the pair of arcuate surfaces 86 at the main locking position. The curved surface 76A contacts the arcuate surface 86 in the left - right direction and also in the up - down direction. For this reason, the elliptical terminal 81 does not rattle in the left - right direction and does not drop downward at the main locking position. Also, as shown in FIG. 10, since the pair of curved surfaces 76A are partially in contact with the pair of arcuate surfaces 86 even at the temporary locking position, the elliptical terminal 81 does not rattle in the left - right direction and does not drop downward at the temporary locking position. The elliptical terminal 81 is held in the male housing body 61 in a state where the arcuate surface 86 of the front - side cylindrical portion 84A is supported from both left - right sides by the pair of support walls 76 at both the temporary locking position and the main locking position. That is, the curved surface 76A supports the front - side cylindrical portion 84A from both left - right sides in a state of being in contact with the arcuate surface 86.

[0033] The pair of support walls 76 support the front portion of the outer peripheral surface of the front - side cylindrical portion 84A that is more forward than the front end of the insulating member 85 at both the temporary locking position and the main locking position. At the temporary locking position, the front ends of the pair of support walls 76 are located more forward than the front end of the front - side cylindrical portion 84A.

[0034] At the temporary locking position, since the pair of deflection - suppressing portions 75 are in a state of retreating from the deflection spaces of the pair of lances 65, the deflection of the pair of lances 65 is allowed. On the other hand, at the main locking position, since the pair of deflection - suppressing portions 75 have entered the deflection spaces of the pair of lances 65, the deflection of the pair of lances 65 is suppressed. For this reason, at the main locking position, the elliptical terminal 81 is double - locked by the pair of lances 65 and the pair of deflection - suppressing portions 75.

[0035] Figure 12 shows the state where the male housing 60 and the female housing 20 are properly fitted. 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. The female connector 10 has the same configuration as the male connector 50 as described above. That is, the female connector 10 includes a female housing 20 that can be fitted into the male housing 60, and a female retainer 30 that is attached to the female housing 20. The female retainer 30 includes a female retainer body 31, a pair of support walls 32, and a pair of deflection 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 support the outer peripheral surface of the front cylindrical portion 84A of the elliptical terminal 81 from both sides in the left-right direction. The female housing 20 corresponds to the "opposite housing" of the present disclosure, the female retainer 30 corresponds to the "opposite retainer" of the present disclosure, and the support wall 32 corresponds to the "opposite support wall" of the present disclosure.

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

[0037] As shown in Figure 13, the front cylindrical portion 84A of the elliptical terminal 81 is supported from both sides in the left-right direction by both the pair of support walls 76 of the male retainer 70 and the pair of support walls 32 of the female retainer 30. As shown in Figure 11, a part of the front cylindrical portion 84A protrudes forward from the front ends of the pair of support walls 76, and this protruding portion is supported by the pair of support walls 32 of the female retainer 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 both the male and female retainers 30 and 70, so that wear of the contact portion is easily suppressed.

[0038] (Operation and Effect of the Embodiment) (1) The male connector 50 of the embodiment has a plurality of types of male terminals 80 arranged side by side in the left-right direction, and a plurality of male cavities 63 that respectively accommodate the plurality of types of male terminals 80. The male housing 60 has male terminals 80 inserted into the male cavities 63 from the rear in the front-rear direction intersecting the left-right direction. The male retainer 70 is mounted on the male housing 60 from the front in the front-rear direction. A pair of lances 65 arranged side by side in the left-right direction are formed on the inner wall of the male cavity 63. The plurality of types of male terminals 80 each have at least one elliptical terminal 81 having an elliptical shape in a front view. The elliptical terminal 81 has a front-side cylindrical portion 84A that opens forward and is long in the left-right direction, and a pair of locked portions 87 that hold the elliptical terminal 81 by locking the pair of lances 65 respectively. The pair of lances 65 are bendable in the left-right direction. The male retainer 70 has a pair of bending suppression portions 75 that respectively enter the bending spaces of the pair of lances 65 to suppress the bending of the pair of lances 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 configuration, the pair of support walls 76 support the front-side cylindrical portion 84A of the elliptical terminal 81 from both sides in the left-right direction, 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 retainer 70, regardless of the tolerance for assembling the male retainer 70 to the male housing 60, by providing the pair of support walls 76 in accordance with the left-right dimension of the elliptical terminal 81, rattling of the elliptical terminal 81 in the male cavity 63A can be suppressed.

[0040] (2) The elliptical terminal 81 has a pin terminal 83 that is housed in the front-side cylindrical portion 84A and is long 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 more forward than the front end of the insulating member 85. By supporting, with the pair of support walls 76, a portion of the outer peripheral surface of the front-side cylindrical portion 84A that is more forward than the front end of the insulating member 85, it becomes easier to suppress rattling of the elliptical terminal 81 in the male cavity 63A.

[0041] (3) The front cylindrical portion 84A has a pair of arcuate surfaces 86 located 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 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, with the curved surface 76A of each support wall 76 in contact with the arcuate surface 86 of the front cylindrical portion 84A, the front cylindrical portion 84A of the elliptical terminal 81 can be supported from both sides in the left-right direction.

[0042] (4) The male retainer 70 is movable between a temporary locking position that allows the deflection of the pair of lances 65 and a main locking position that suppresses the deflection of the pair of lances 65. 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. Since the front ends of the pair of support walls 76 are located forward 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 in the temporary locking position.

[0043] (5) The connector device 100 of the present disclosure is a connector device 100 further including a male connector 50, a female housing 20 that can be fitted to the male housing 60, and a female retainer 30 attached to the female housing 20. The female retainer 30 has a pair of support walls 32 that support the outer peripheral surface of the front cylindrical portion 84A from both sides in the left-right direction together with the pair of support walls 76 when the male housing 60 and the female housing 20 are fitted together. According to such a configuration, both the pair of support walls 76 and the pair of support walls 32 support the front cylindrical portion 84A of the elliptical terminal 81 from both sides in the left-right direction, thereby preventing the elliptical terminal 81 from moving in the left-right direction.
