Technical field

[0001] The present invention relates to a shielding connector. State of the art

[0002] JP 2012-129103 A discloses a shield connector comprising a terminal unit that houses an inner conductor terminal in a dielectric, an outer conductor that constitutes a shield terminal by surrounding the terminal unit, and a housing for housing the shield terminal. In the shield connector of this type, a structure for locking a resiliently deflectable locking lance formed in the housing to a locking projection formed on an outer surface of the outer conductor is considered as means for retaining and holding the shield terminal inserted into the housing.

[0003] Furthermore, the document US 2009 / 0186512 A1 discloses a connector having round large terminals connected to ends of shielded wires, a small terminal connected to one end of an insulated wire, and a housing in which two large cavities for receiving the large terminals are arranged side by side and a small cavity for receiving the small terminal is arranged at a position between the two large cavities and offset from the two large cavities in a direction orthogonal to an arrangement direction of the large cavities. Summary of the inventionTechnical problem

[0004] Since the locking lance is resiliently deflectable, the locking lance may be disengaged from the locking projection due to impact, vibration, or the like. Thus, it is desired to improve the reliability of a shield terminal retaining function.

[0005] The present invention has been completed based on the above situation and aims to improve the reliability of a shield terminal retention function. Solution to the problem

[0006] A first aspect of the invention is directed to a shield connector comprising: a shield terminal having an inner conductor having a contact pin projecting forwardly from a body portion, a dielectric configured to retain the inner conductor while the body portion is received, and an outer conductor surrounding the dielectric and the contact pin; a first housing including a resiliently deflectable first locking lance, a front retainer capable of limiting resilient deflection of the first locking lance, and a first receiving chamber; and a second housing including a resiliently deflectable second locking lance, a second receiving chamber, and a side retainer directed into the interior of the second receiving chamber; wherein the shield terminal is selectivelyselectively mountable into the first housing and the second housing, wherein: a first locking portion and a second locking portion are formed on an outer surface of an upper plate portion of the outer conductor; the shield terminal is retained by the front retainer that restricts resilient deflection of the first locking lance and the first locking portion that is locked to the first locking lance when the shield terminal is inserted into the first accommodating chamber; and the shield terminal is retained by locking the first locking portion and the second locking lance and locking the second locking portion and the side retainer when the shield terminal is inserted into the second accommodating chamber.

[0007] A second aspect of the invention is directed to a shield connector configured by selectively inserting a shield terminal into one of a first receiving chamber formed in a first housing and a second receiving chamber formed in a second housing, the shield terminal including an inner conductor having a contact pin projecting forwardly from a body portion, a dielectric configured to retain the inner conductor while the body portion is received, and an outer conductor surrounding the dielectric and the contact pin, comprising: a resiliently deflectable first locking lance formed in the first receiving chamber; a front retainer configured to restrict resilient deflection of the first locking lance by being mounted in the first housing;a resiliently deflectable second locking lance formed in the second accommodating chamber; a side retainer mounted in the second housing to face the interior of the second accommodating chamber; a first locking portion formed on an outer surface of an upper plate portion of the outer conductor and configured to retain the shield terminal by being locked to the first locking lance when the shield terminal is inserted into the first accommodating chamber, and to retain the shield terminal by being locked to the second locking lance when the shield terminal is inserted into the second accommodating chamber;and a second locking portion formed on the outer surface of the upper plate portion of the outer conductor and configured to retain the shield terminal by being locked to the side retainer when the shield terminal is inserted into the second accommodating chamber; Effect of the invention

[0008] When the shield terminal is inserted into the first receiving chamber, the first locking portion is locked to the first locking lance, and the front retainer is mounted in the first housing to restrict the resilient deflection of the first locking lance, thereby reliably retaining the shield terminal. When the shield terminal is inserted into the second receiving chamber, the first locking portion is locked to the second locking lance, and the side retainer is locked to the second locking portion, thereby reliably retaining the shield terminal. The shield terminal can be used as a common member for the first and second housings of different types.

Embodiments of the invention

[0009] In the first and second aspects of the invention, the first locking portion and the second locking portion may be formed on the same plane of the outer surface of the outer conductor and arranged at mutually different positions in a width direction that intersects an insertion direction into the first accommodating chamber or the second accommodating chamber. According to this configuration, the first locking portion can avoid interference with the side retainer, and the second locking portion can avoid interference with the first and second locking lances while the first and second locking portions are arranged on the same plane.

[0010] In the first and second aspects of the invention, the first locking portion may be arranged at a central position in the width direction that intersects the insertion direction into the first accommodating chamber or the second accommodating chamber, and a pair of second locking portions may be arranged on both sides across the first locking portion in the width direction. According to this configuration, since a pair of projections spaced apart in the width direction are locked to the side retainer, the shield terminal can be prevented from being tilted laterally.

[0011] In the first and second aspects of the invention, a front stopper portion configured to restrict movement of the shield terminal inserted into the first accommodating chamber or the second accommodating chamber beyond a proper insertion position may be formed in a planar region of the outer surface of the outer conductor different from a planar region where the first locking portion is formed. Since the planar region where the front stopper portion is formed is different from the planar region where the first locking portion is formed, the first and second locking lances do not resiliently contact the front stopper portion. Thus, insertion resistance due to the resilient cooperation of the front stopper portion with the first or second locking lance is not generated. <Ausführungsform>

[0012] Hereinafter, a specific embodiment of the present invention will be described with reference to Fig. 1 to 11. It should be noted that in the following description a left side in Fig. 1 to 11 is defined as a front side relating to a front-back direction. An upper and lower side, which in Fig. 1 to 3, 5 to 8, 10 and 11 are directly defined as an upper and lower side concerning a vertical direction.

[0013] A shield terminal 30 of this embodiment constitutes a first shield connector A (shield connector as claimed) of a waterproof type by being mounted in a first housing 10, and constitutes a second shield connector B (shield connector as claimed) of a non-waterproof type by being mounted in a second housing 20.

[0014] The first housing 10 is made of a synthetic resin and is, as shown in Fig. 2 to 4, a single component including a receiving portion 11 and a receptacle 12 extending forward from the outer periphery of the front end of the receiving portion 11. A first receiving chamber 13 is formed inside the receiving portion 11. The shield terminal 30 is inserted into the receiving chamber 13 from behind the first housing 10. A first locking lance 14, which projects forward and is resiliently deflectable upward, is formed on an inner upper surface of the first receiving chamber 13. Step-like first stoppers 15 (see Fig. 4) are formed on both left and right side surfaces inside the first receiving chamber 13.

[0015] The receiving portion 11 is formed with a deflection space 16 to allow the first locking lance 14 to be resiliently deflected upward. A front retainer 17 is mounted in the receiving portion 11 from the front of the first housing 10. The front retainer 17, which is mounted in the receiving portion 11, is movable in the front-rear direction between a partial locking position where the front retainer 17 is retracted forward in the deflection space 16 to allow the resilient deflection of the first locking lance 14, as shown in Fig. 3, and a fully locking position where the front retainer 17 enters the deflection space 16 to limit the resilient deflection of the first locking lance 14, as shown in Fig. 2. The deflection space 16 is not open in the outer peripheral surface of the receiving portion 11 and is open in the front end surface of the receiving portion 11.

[0016] The second housing 20 is made of a synthetic resin. As shown in Fig. 6 and Fig. 7, a second accommodating chamber 21 is formed inside the second housing 20. The shield terminal 30 is inserted into the second accommodating chamber 21 from behind the second housing 20. A second locking lance 22, which projects forward and resiliently deflects upward, is formed on an inner upper surface of the second accommodating chamber 21. Second stoppers (not shown) having the same shape (step-like shape) as the first stoppers 15 are formed on both left and right side surfaces inside the second accommodating chamber 21.

[0017] The second housing 20 is formed with a mounting hole 23 that communicates with the interior of the second accommodating chamber 21 through the upper surface (outer surface) thereof. The mounting hole 23 is located behind the second locking lance 22. A side retainer 24 is mounted in the mounting hole 23. The side retainer 24 mounted in the mounting hole 23 is movable in the vertical direction (direction intersecting an insertion / removal direction of the shield terminal 30 into and out of the second accommodating chamber 21) between a partial locking position where the side retainer 24 is retracted to the exterior of the second accommodating chamber 21, as shown in Fig. 7, and a fully locking position where the side retainer 24 is arranged in the receiving chamber 21, as shown in Fig. 6 is shown.

[0018] The shield terminal 30 is a connecting member that forms a wiring for an Ethernet (registered trademark) high-speed communication circuit of a motor vehicle. The shield terminal 30 is formed such that a terminal unit 31 is surrounded by an outer conductor 43 in the shape of a rectangular tube made of a metal material. The terminal unit 31 is configured by enclosing a pair of inner conductors 32 in a dielectric 40.

[0019] The inner conductor 32 is shaped to be long in the front-back direction as a whole. The inner conductor 32 includes a body portion 33 in the shape of a rectangular tube, an elongated contact pin 34 projecting forward from the body portion 33, and a crimping portion 35 in the shape of an open barrel connected to the rear end of the body portion 33. A front end part of a wire 36 is conductively fixed to the crimping portion 35. A pair of the wires 36 connected to two inner conductors 32 constitutes a twisted pair cable 37.The dielectric 40 is configured by uniting a first component 41 made of a synthetic resin and having a halved shape and a second component 42 made of a synthetic resin and having a halved shape in the vertical direction (direction which intersects axes of the front end part of the wires 36).

[0020] The outer conductor 43 is configured by combining a first shell 44 having a halved shape and a second shell 50 having a halved shape to sandwich the terminal unit 31 therebetween. First and second barrel portions 48, 53 formed on a rear end portion of the outer conductor 43 are conductively fixed to a stranded wire 38 of the twisted pair cable 37. The shield terminal 30, which is fixed to the twisted pair cable 37, is mounted in the first housing 10 and the second housing 20 by being inserted therein from the rear.

[0021] As this is Fig. As shown in Fig. 10, the first shell 41 includes a receptacle 45 in the shape of a rectangular tube, a bottom plate portion 46 extending rearward from the receptacle 45, a pair of left and right side plate portions 47 projecting upward from both left and right side edges of the bottom plate portion 46, and the first drum portion 48 in the shape of an open drum connected to the rear end of the bottom plate portion 46. A pair of front and rear locking holes 49 are formed in each of the side plate portions 47 by recessing the side plate portion 47 on an outer surface side and an outer surface side, respectively.

[0022] As this is Fig.As shown in Fig. 11, the second shell 50 includes an upper plate portion 51 which is long in the front-back direction, a pair of left and right outer plate portions 52 extending downward from both left and right side edges of the upper plate portion 51, and the second drum portion 53 in the shape of an open drum connected to the rear end of the upper plate portion 51. A pair of front and rear locking projections 54 are formed on each outer plate portion 52 by causing parts of the inner surface of the outer plate portion 52 to protrude.

[0023] A projection-like first locking portion 55 is integrally formed on the upper surface (outer surface) of the upper plate portion 51. The first locking portion 55 is formed by cutting a part of the upper plate portion 51 and lifting the cut part upward. The first locking portion 55 is arranged on a front end part of the upper plate portion 51 in the front-back direction and at a center of the upper plate portion 51 in a lateral direction. A front end part of the first locking portion 55 is formed with an inclined surface 56 which is inclined relative to the front-back direction (insertion direction of the shield terminal 30 into the housing). A rear end surface of the first locking portion 55, which is a cut and raised surface, serves as a locking portion.Locking surface substantially at a right angle to the forward-backward direction.

[0024] A pair of left and right second locking portions 57 are formed on the upper surface (outer surface) of the upper plate portion 51. The pair of left and right second locking portions 57 are formed by cutting parts of the upper plate portion 51 and raising the cut parts. Rear end surfaces of the second locking portions 57, which are cut and raised surfaces, serve as locking surfaces substantially at a right angle to the front-back direction. The pair of left and right second locking portions 57 are arranged substantially at central positions (i.e., positions rearward of the first locking portion 55) in the front-back direction and outward from the first locking portion 55 in the lateral direction.

[0025] The pair of left and right outer plate portions 52 are formed with a pair of front stopper portions 58. The front stopper portion 58 is formed by cutting a part of the outer plate portion 52 and raising the cut part. A front end surface of the front stopper portion 58, which is a cut and raised surface, serves as a front stopper surface substantially at a right angle to the front-rear direction. The front stopper portion 58 is arranged at a position forward of a center of the outer plate portion 52 in the front-rear direction and between the first locking portion 55 and the second locking portions 57. The front stopper portion 58 is arranged on a lower end part of the outer plate portion 52 in the vertical direction.

[0026] When assembling the first shell 44 and the second shell 50, the terminal unit 31 is first mounted in the first shell 44. At this time, the dielectric 40 is housed in a concave part formed by the bottom plate portion 46 and the two left and right side plate portions 47, and the contact pins 34 projecting forward from the front end surface of the dielectric 40 are surrounded by the receptacle 45. After the terminal unit 31 is mounted in the first shell 44, the second shell 50 is joined to the first shell 44 from above.

[0027] At this time, the outer plate portions 52 of the second shell 50 overlap on the outer surfaces of the side plate portions 47 of the first shell 44, and the locking holes 49 and the locking projections 54 are locked together. By locking the locking holes 49 and the locking projections 54, the first shell 44 and the second shell 50 are locked in a united state to construct the outer conductor 43, and the terminal unit 31 is assembled in a state accommodated in the outer conductor 43. In this way, the assembly of the shield terminal 30 is completed.

[0028] When mounting the shield terminal 30 into the first housing 10, a rubber plug 19 is pre-mounted on the outer periphery of the twisted pair cable 37, and the shield terminal 30 is inserted into the first accommodating chamber 13 from behind the first housing 10 with the front retainer 17 held at the partially locked position. In the process of inserting the shield terminal 30, the inclined surface 56 of the first locking portion 55 resiliently deflects the first locking lance 14.

[0029] When the shield terminal 30 is properly inserted, the front stopper portions 58 abut against the first stoppers 15 to stop the shield terminal 30 at the front, and the locking portion 55 is locked to the first locking lance 14 to retain the shield terminal 30 relative to the first housing 10. Further, an opening on the rear end of the first accommodating chamber 13 is sealed in a liquid-tight manner by the rubber plug 19. In this way, the shield terminal 30 is primarily locked.

[0030] After the shield terminal 30 is properly inserted, the front retainer 17 is pushed from the partial locking position to the full locking position to enter the deflection space 16. In this way, the resilient deflection of the first locking lance 14 in a direction separating it from the first locking portion 55 is restricted, and therefore the shield terminal 30 is secondarily locked. As just described, the shield terminal 30 is reliably retained by primary locking by the first locking lance 14 and secondary locking by the front retainer 17.

[0031] When mounting the shield terminal 30 into the second housing 20, the shield terminal 30 is inserted into the second receiving chamber 21 with the side retainer 24 held at the partially locked position. In the process of inserting the shield terminal 30, the inclined surface 56 of the second locking portion 55 resiliently deflects the second locking lance 22. When the shield terminal 30 is properly inserted, the front stopper portions 58 abut against the second stoppers to stop the shield terminal 30 at the front, and the first locking portion 55 is locked to the second locking lance 22 to retain the shield terminal 30 relative to the second housing 20. In the above manner, the shield terminal 30 is primarily locked.

[0032] After the shield terminal 30 is properly inserted, the side retainer 24 is slid from the partially locked position to the fully locked position to enter the second accommodating chamber 21. In this way, the side retainer 24 is locked at the second locking portions 57 from behind, and therefore the shield terminal 30 is secondarily locked. As just described, the shield terminal 30 is reliably retained by primary locking by the second locking lance 22 and secondary locking by the side retainer 24.

[0033] The first shield connector A of this embodiment is configured by inserting the shield terminal 30 into the first accommodating chamber 13 formed in the first housing 10. Further, the second shield connector B is configured by inserting the shield terminal 30 into the second accommodating chamber 21 formed in the second housing 20.

[0034] The shield terminal 30 includes the terminal unit 31 and the outer conductor 43. The terminal unit 31 includes the pair of inner conductors 32 having the contact pins 34 projecting forward from the body portions 33, and the dielectric 40 configured to hold the inner conductors 32 while accommodating the body portions 33 inside. The terminal unit 31 is received in the outer conductor 43.

[0035] This shield terminal 30 is selectively mounted in the first housing 10 and the second housing 20. In other words, the shield terminal 30 can be mounted in both the first housing 10 and the second housing 20, and is mounted or arranged in one of the first housing 10 and the second housing 20 according to requirements.

[0036] The first housing 10 includes the resiliently deflectable first locking lance 14, the front retainer 17 capable of restricting the resilient deflection of the first locking lance 14, and the first receiving chamber 13. The second housing 20 includes the resiliently deflectable second locking lance 22, the second receiving chamber 21, and the side retainer 24 directed toward the interior of the second receiving chamber 21.

[0037] The first locking portion 55 and the second locking portions 57 are formed on the outer surface of the outer conductor 43. When the shield terminal 30 is inserted into the first accommodating chamber 13, the first locking portion 55 is locked to the first locking lance 14, and the front retainer 17 restricts the resilient deflection of the first locking lance 14. In the above manner, the shield terminal 30 is reliably retained. Furthermore, when the shield terminal 30 is inserted into the second accommodating chamber 21, the shield terminal 30 is reliably retained by the locking of the first locking portion 55 and the second locking lance 22, and the locking of the second locking portions 57 and the side retainer 24.

[0038] As just described, the reliability of a retaining function of the shield terminal 30 is excellent regardless of whether the shield terminal 30 of this embodiment is mounted in the first housing 10 or the second housing 20. Furthermore, the shield terminal 30 can be used as a common member for the waterproof first housing 10 and the non-waterproof second housing 20, which are of different types.

[0039] Furthermore, the first locking portion 55 and the second locking portions 57 are formed on the same plane of the outer surface of the outer conductor 43 (outer surface of the upper plate portion 51) and arranged at mutually different positions in a width direction (lateral direction) that intersects the insertion direction into the first or second accommodating chamber 13 or 21. According to this configuration, the first locking portion 55 can avoid interference with the side retainer 24, and the second locking portions 57 can avoid interference with the first and second locking lances 14, 22 while the first locking portion 55 and the second locking portions 57 are arranged on the same plane.

[0040] Furthermore, the first locking portion 55 is disposed at the central position of the upper plate portion 51 in the width direction (lateral direction), which intersects the insertion direction into the first or second accommodating chamber 13 or 21, and the pair of second locking portions 57 are disposed on both sides across the first locking portion 55 in the width direction. According to this configuration, since a pair of protrusions spaced apart from each other in the width direction are locked to the side retainer 24, the shield terminal 30 can be prevented from being tilted laterally.

[0041] Furthermore, the front stopper portions 58, which are configured to restrict movement of the shield terminal 30 inserted into the first or second accommodating chamber 13 or 21 beyond a proper insertion position, are formed in planar regions (outer plate portions 52) of the outer surface of the outer conductor 43 different from a planar region (upper plate portion 51) where the first locking portion 55 is formed. Since the planar regions (outer plate portions 52) where the front stopper portions 58 are formed are different from the planar region (upper plate portion 51) where the first locking portion 55 is formed, the first locking lance 14 and the second locking lance 22 do not resiliently come into contact with the front stopper portions 58. Thus, insertion resistance due to resilient collision is reduced.-action of the front stop portions 58 with the first or second locking lance 14 or 22 is not generated or produced. <Andere Ausführungsformen>
