[0004] [Patent Document 1] JP 2013-4281 A [Patent Document 2] Japanese Patent Application Laid-Open No. 2014-107139 Summary of the Invention [Problem to be solved by the invention]

[0005] Generally, a terminal fitting is placed in a cavity of a housing and locked by a lance. A die-removal hole resulting from the removal of a mold used to form the locking surface of the lance is formed in the front surface of the housing. If lances were formed in the wall separating adjacent cavities in the width direction, corresponding to each cavity, a large number of die-removal holes would be required for each cavity in the front surface of the housing, which could result in the housing becoming larger in the width direction.

[0006] Therefore, an object of the present disclosure is to provide a connector that can prevent the housing from becoming large in width. [Means for solving the problem]

[0007] The connector of the present disclosure comprises a housing and terminal fittings, wherein the housing has a plurality of cavities extending in the front-to-rear direction and arranged side by side in the width direction, a shared wall arranged between adjacent cavities in the width direction, and a pair of lances protruding forward from the shared wall and arranged corresponding to each of the adjacent cavities in the width direction, wherein the terminal fittings are engaged with the lances within the cavities, the pair of lances are arranged side by side in the height direction on the shared wall, and the housing has a shared space portion that is open to the front of the pair of lances. [Effects of the Invention]

[0008] According to the present disclosure, it is possible to provide a connector that can prevent the housing from becoming large in width. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0010] [Description of the embodiments of the present disclosure] First, embodiments of the present disclosure will be listed and described. The connector of the present disclosure comprises: (1) A housing and a terminal fitting, wherein the housing has a plurality of cavities extending in the front-to-rear direction and arranged side by side in the width direction, a common wall arranged between adjacent cavities in the width direction, and a pair of lances protruding forward from the common wall and arranged corresponding to each of the adjacent cavities in the width direction, the terminal fittings are engaged with the lances within the cavities, the pair of lances are arranged side by side in the height direction on the common wall, and the housing has a common space portion that is open to the front of the pair of lances.

[0011] Since the pair of lances are arranged side by side in the height direction on the common wall, it is possible to prevent the housing from becoming large in the width direction. Also, since the housing has a common space that opens in front of the pair of lances, the front portions of the lances can be easily molded through the common space.

[0012] (2) It is preferable that the housing has a mating housing, and the mating housing has a hood that can be fitted to the housing, and a partition portion that protrudes into the hood and is positioned in the shared space portion when the housing and the mating housing are fitted together.

[0013] When the housing and the mating housing are mated, the partition portion is positioned in the shared space portion, so that adjacent cavities in the width direction are separated by the partition portion, thereby electrically insulating the terminal fittings positioned in each adjacent cavity.

[0014] (3) Preferably, six mating terminals protrude into the hood, and the protruding ends of the mating terminals are recessed rearward from the protruding ends of the partition portions.

[0015] If the housing and the mating housing are mated at an angle from the correct mating position, the housing will hit the protruding tip of the partition and avoid interfering with the mating terminals, thereby protecting the mating terminals. In other words, twisted mating of the connector can be prevented. In particular, because the partition has the function of preventing twisted mating and the function of maintaining insulation between the terminal fittings, the configuration of the mating housing can be simplified compared to when both functions are formed in separate locations.

[0016] (4) The terminal fittings have a terminal body and a locking protrusion protruding from the terminal body, and in a pair of the terminal fittings respectively arranged in the cavities adjacent in the width direction, the locking protrusions are preferably arranged side by side in the height direction in the shared space portion so as to be locked to the pair of lances, and protrude in the height direction.

[0017] Since the locking projections of the pair of terminal fittings are arranged side by side in the height direction in the shared space and protrude in the height direction, the pair of terminal fittings can be accommodated in the cavity with a small pitch in the width direction, which more reliably prevents the housing from becoming large in the width direction.

[0018] [Details of the embodiments of the present disclosure] Specific examples of the present disclosure will be described below with reference to the drawings. However, 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.

[0019] <Embodiment 1> The connector according to the first embodiment of the present disclosure is a shielded connector. As shown in FIGS. 1 and 2, the connector is composed of a female connector 10 and a male connector 60. The female connector 10 includes terminal fittings 11, a housing 12, and a retainer 13. As shown in FIG. 2, the male connector 60 is mounted on a circuit board 100 and includes mating terminals 61 and a mating housing 73. The housing 12 and the mating housing 73 are matable with each other. In the following description, the front-rear direction refers to the side of the female connector 10 and the male connector 60 that faces each other when mated. The up-down direction is based on the up-down direction in each drawing except for FIG. 3. In the following description, the up-down direction is synonymous with the height direction, and the left-right direction is synonymous with the width direction.

[0020] (Terminal fittings) 2 and 8, the terminal fitting 11 is a coaxial terminal and has an inner conductor 14, an outer conductor 15 surrounding the inner conductor 14, and a dielectric 16 disposed between the inner conductor 14 and the outer conductor 15. Although not shown in detail, the dielectric 16 is made of synthetic resin, houses the inner conductor 14, and maintains an insulating state between the inner conductor 14 and the outer conductor 15. The inner conductor 14 is a plate made of conductive metal and has a cylindrical shape, and as shown in FIG. 8, the rear end is electrically connected to a core wire 91 of an electric wire 90 (coaxial cable).

[0021] The outer conductor 15 is a plate made of conductive metal and has a terminal body 17, a locking projection 18 (see Figs. 4 and 8) projecting in the height direction from the terminal body 17, and barrels 19, 21 continuing to the rear of the terminal body 17. As shown in Fig. 2, the barrel has a shield barrel portion 19 that is crimped to and electrically connected to a shield portion 92 such as a braided wire of the electric wire 90, and a sheath barrel portion 21 that is crimped to and mechanically connected to a sheath 93 of the electric wire 90 behind the shield barrel portion 19.

[0022] The terminal body 17 has a cylindrical tubular portion 22 that houses the dielectric 16 inside. As shown in Fig. 2, a terminal fitting space 23 is formed between the front end of the dielectric 16 and the tubular portion 22, into which an outer conductor tube 63 (described later) of the mating terminal 61 can be fitted.

[0023] As shown in Fig. 8, the terminal body 17 has a pair of side walls 24 between it and the shield barrel portion 19. The locking projection 18 has a rectangular plate shape, protrudes from one of the side walls 24, and is double-folded in the width direction as shown in Fig. 4. A retainer locking projection 25, which is longer in the front-to-rear direction than the locking projection 18, is formed on the other of the side walls 24. The retainer locking projection 25 also has a rectangular plate shape, and is double-folded in the width direction.

[0024] 2, 3, and 8, the outer conductor 15 has a cover 26 attached to the terminal body 17. The cover 26 covers the periphery of the connection between the inner conductor 14 and the core wire 91 between the side walls 24, and is arranged to cover the outer periphery of the shield barrel portion 19.

[0025] (housing) 5 and 9, the housing 12 is made of synthetic resin and has a housing main body 27 and a lock arm 28 that protrudes from the housing main body 27. The lock arm 28 extends rearward from the top surface of the housing main body 27 and is capable of bending and deforming in the vertical direction. Although not shown, the lock arm 28 engages a mating locking portion 69 (see FIG. 7) of the mating housing 73, which will be described later, to maintain the housing 12 and the mating housing 73 in a fitted state.

[0026] The housing body 27 has a plurality of cavities 29. The cavities 29 are arranged in pairs, one above the other, in the width direction of the housing body 27, with a plurality of cavities (two in the first embodiment) arranged side by side. Each cavity 29 penetrates the housing body 27 in the front-rear direction. The front portion of each cavity 29 has a circular cross section, allowing the terminal fitting 11 to be inserted from the rear. As shown in FIG. 1 , a plurality of clearance-reducing ribs 31 that can come into contact with the cylindrical portion 22 of the terminal fitting 11 are formed on the inner peripheral surface of the front portion of each cavity 29.

[0027] 6 and 9, the housing body 27 has a pair of retainer attachment holes 32. The retainer attachment holes 32 are rectangular openings on the left and right side surfaces of the housing body 27 and communicate with the rear parts of the upper and lower cavities 29. As shown in FIG. 3, the retainer 13 can be inserted into the retainer attachment holes 32 from the side.

[0028] As shown in Figures 5 and 9, the housing body 27 has a lateral wall 33 in the vertical center that extends along the width direction and separates the upper and lower cavities 29. Furthermore, the housing body 27 has a common wall 34 in the horizontal center that extends along the height direction and separates the rear portions of the left and right cavities 29, as shown in Figures 3 and 9. At the rear of the housing body 27, the common wall 34 and the lateral wall 33 intersect in a cross shape, as shown in Figure 9. The side surface of the common wall 34 can be seen from the side of the housing body 27 through the retainer attachment hole 32.

[0029] 5, the housing main body 27 has a plurality of lances 35A, 35B protruding forward from the common wall 34. Each lance 35A, 35B is arranged corresponding to a respective cavity 29. In the common wall 34 between adjacent cavities 29 in the width direction, a pair of lances 35A, 35B is arranged side by side with a vertical offset. Specifically, the pair of lances includes a first lance 35A arranged corresponding to the upper side of the cavity 29 and a second lance 35B arranged corresponding to the lower side of the cavity 29.

[0030] The first lance 35A and the second lance 35B have the same shape and include a plate-like lance body 36 that protrudes forward from the shared wall 34, and a lance protrusion 37 that protrudes from the lance body 36 toward the corresponding cavity 29. The lance body 36 is arranged with its left and right plate surfaces facing the width direction, and is formed within the wall thickness of the shared wall 34 for both the first lance 35A and the second lance 35B. As shown in Fig. 5, of the left and right plate surfaces of the lance body 36, the plate surface on the inner side in the width direction, which is closer to the widthwise center of the housing body 27, forms a vertical surface 38 along the up-down direction. The vertical surfaces 38 of the first lance 35A and the second lance 35B are arranged along a central axis C1 that passes through the widthwise center of the housing body 27. The vertical surfaces 38 of the first lance 35A and the second lance 35B define respective deflection spaces 39 between the opposing cavities 29. The first lance 35A and the second lance 35B are capable of deflection deformation in the deflection spaces 39 independently of each other.

[0031] The lance protrusions 37 protrude from the upper front portion of the lance body 36 of the first lance 35A and the lower front portion of the lance body 36 of the second lance 35B. That is, each lance protrusion 37 is disposed on a side of the pair of lances 35A, 35B that is spaced apart in the height direction. The front surface of the lance protrusions 37 forms the front surface of the entire lances 35A, 35B, and as shown in FIG. 3, is inclined forward as it moves outward in the width direction (toward the tip in the protruding direction). The protruding dimension of the lance protrusions 37 corresponds to the width dimension (plate thickness) of the locking protrusions 18.

[0032] The housing body 27 has a shared space 41 open in front of the pair of lances 35A, 35B. One shared space 41 is formed between adjacent cavities 29 in the width direction. Adjacent cavities 29 in the width direction communicate with each other at the front via the shared space 41.

[0033] As shown in Figure 5, a peripheral edge 42 is formed on the front surface of the housing body 27 for each cavity 29, defining the opening edge of the cavity 29. Each peripheral edge 42 is C-shaped when viewed from the front of the housing body 27, with a slit 44 between both ends of the C opening on the side where the lances 35A and 35B are located. Therefore, the slits 44 of the peripheral edge 42 are offset in the height direction to correspond to the first lance 35A and the second lance 35B in adjacent cavities 29 in the width direction. The peripheral edge 42 has a tapered guide surface 45 that recedes radially inward.

[0034] 6, the housing body 27 has a plurality of temporary locking portions 46 and full locking portions 47 that can lock the retainer 13. Each pair of temporary locking portions 46 and full locking portions 47 protrudes from the upper and lower surfaces of the housing body 27, one pair on each side.

[0035] (retainer) A pair of retainers 13 is provided for each retainer mounting hole 32 (see FIG. 4). Each retainer 13 is made of synthetic resin and has a plate-like covering portion 48 that extends in the up-down direction, and a pair of protruding pieces (not shown) that protrude inward in the width direction (toward the center of the housing body 27 in the width direction) from the upper and lower ends of the covering portion 48. The protruding pieces are arranged to cover the upper and lower surfaces of the housing body 27, respectively, and are capable of being engaged with the temporary locking portions 46 and the full locking portions 47 of the housing body 27.

[0036] The covering portion 48 has a rectangular shape in a side view and closes the opening of the retainer attachment hole 32 in the side of the housing body 27. A plurality of restricting portions 51 that can be engaged with the terminal fittings 11 are protruded from the inner surface of the covering portion 48 on the inner side in the width direction. As shown in FIG. 4 , each restricting portion 51 is provided in a pair for each of the upper and lower cavities 29.

[0037] The retainer 13 is arranged relative to the housing main body 27 so as to be movable between a temporary locking position and a full locking position. At the temporary locking position, the covering portion 48 is arranged to the side of the retainer attachment hole 32, and the protruding portions are engaged with the temporary locking portions 46, restricting movement of the retainer 13 in the width direction. At the temporary locking position, each restricting portion 51 is arranged retracted laterally from the cavity 29, allowing insertion of the terminal fitting 11 into the cavity 29. The retainer 13 can be pushed inward in the width direction to reach the full locking position. At the full locking position, the covering portion 48 closes the opening of the retainer attachment hole 32, and the protruding portions are engaged with the full locking portions 47, restricting movement of the retainer 13 to the temporary locking position. 3, in the full locking position, each restricting portion 51 is positioned so as to enter the cavity 29 and be able to be locked from the rear by the retainer locking projections 25 of the terminal fittings 11 arranged in the cavity 29. The terminal fittings 11 are locked by the restricting portions 51, thereby preventing them from slipping out rearward from the housing 12. As will be described later, the terminal fittings 11 are primarily locked by the lances 35A and 35B before being locked by the restricting portions 51 of the retainer 13.

[0038] (Mating terminal) 2, the mating terminal 61 has a mating inner conductor 62, an outer conductor tube 63 surrounding the mating inner conductor 62, and a mating dielectric 64 disposed between the mating inner conductor 62 and the outer conductor tube 63. Although not shown in detail, the mating dielectric 64 is made of synthetic resin, houses the mating inner conductor 62, and maintains insulation between the mating inner conductor 62 and the outer conductor tube 63. The mating inner conductor 62 is made of conductive metal, has a pin shape, is bent into an L-shape, and has a rear lower end that is soldered to a connection hole 101 of the circuit board 100 for electrical connection. The front end of the mating inner conductor 62 protrudes forward from the mating dielectric 64 and is inserted into the inner conductor 14 for electrical connection.

[0039] The outer conductor tube 63 has a cylindrical shape. The front end of the outer conductor tube 63 is guided into the guide surface 45 of the peripheral edge 42 and fitted into the terminal fitting space 23 of the terminal fitting 11, and is electrically connected to the outer conductor 15 of the terminal fitting 11, as shown in FIG.

[0040] As shown in Fig. 7, the male connector 60 has a die-cast housing 65 at the rear. The portion of the mating inner conductor 62 that protrudes rearward from the outer conductor tube 63 is disposed within the housing 65. The outer conductor tube 63 is held by and electrically connected to the housing 65. The housing 65 is electrically connected by soldering to a conductive portion for grounding of the circuit board 100 (see Fig. 2).

[0041] (Matching housing) The mating housing 73 is made of synthetic resin, and as shown in Figures 2 and 7, has a mating housing main body 66 and a cylindrical hood 67 protruding forward from the mating housing main body 66. As shown in Figure 2, the mating housing main body 66 has a plurality of insertion holes 68. Each insertion hole 68 is disposed at a position corresponding to one of the cavities 29 in the mating housing main body 66. Each insertion hole 68 has a circular cross section, and an outer conductor tube 63 can be inserted into it from behind.

[0042] The hood 67 has a rectangular cylindrical shape inside which the housing 12 can be fitted. A mating locking portion 69 is formed on the upper wall of the hood 67. The front end of the mating terminal 61 is disposed so as to protrude into the hood 67.

[0043] A pair of partitions 71 are formed within the hood 67, protruding forward from the front surface of the mating housing main body 66 (which is also the rear surface of the hood 67). Each partition 71 is a plate-like member extending in the up-down direction, has an I-shaped cross section, and is disposed between adjacent insertion holes 68 in the widthwise center of the mating housing 73, although not shown. Each partition 71 is disposed corresponding to the upper and lower cavities 29, respectively. Each partition 71 is also disposed between the front ends of adjacent mating terminals 61 in the widthwise direction. The front end of each partition 71 is located forward of the front ends of the mating terminals 61 within the hood 67.

[0044] When the housing 12 is fitted to the mating housing 73 at an angle, the housing 12 interferes with the front end of the partition 71, protecting the mating terminals 61. This prevents the housing 12 from being forced into the mating housing 73.

[0045] (Connector function and effect) The terminal fitting 11 is inserted into the cavity 29 of the housing 12 from the rear. Here, the terminal fitting 11 takes an insertion posture with the retainer locking protrusion 25 facing outward in the width direction and the locking protrusion 18 facing inward in the width direction. The terminal fitting 11 inserted into the cavity 29 corresponding to the first lance 35A takes an insertion posture with the locking protrusion 18 and the retainer locking protrusion 25 protruding upward (see FIG. 4). The terminal fitting 11 inserted into the cavity 29 corresponding to the second lance 35B takes an insertion posture with the locking protrusion 18 and the retainer locking protrusion 25 protruding downward.

[0046] During the insertion process of the terminal 11, the locking projections 18 interfere with the corresponding lances 35A, 35B, causing the lances 35A, 35B to bend and deform toward the bending space 39. When the terminal 11 is properly inserted into the cavity 29, the locking projections 18 enter the shared space 41, and the lances 35A, 35B elastically return to their original position so that they can be locked to the rear ends of the locking projections 18. By being locked by the lances 35A, 35B, the terminal 11 is primarily prevented from slipping out rearward from the housing 12.

[0047] During the insertion of the terminal fitting 11, the locking projection 18 and the retainer locking projection 25 enter the guide groove 72 (see Figures 4 and 5) of the cavity 29 to guide the insertion of the terminal fitting 11. If the terminal fitting 11 is not in the correct insertion position when the insertion of the terminal fitting 11 begins, the locking projection 18 and the retainer locking projection 25 will not enter the guide groove 72 and will interfere with the rear surface of the housing 12. This prevents the terminal fitting 11 from being inserted into the cavity 29 in the wrong insertion position. In other words, the locking projection 18 and the retainer locking projection 25 function as stabilizers for the terminal fitting 11.

[0048] When the terminal fitting 11 is to be removed from the cavity 29 for maintenance or other reasons, a release tool (not shown) is applied to the lances 35A, 35B through the slits 44 in the peripheral edge 42, causing the lances 35A, 35B to bend toward the bending space 39, thereby releasing the locked state of the terminal fitting 11. In this state, the wire 90 is pulled rearward, and the terminal fitting 11 is removed from the cavity 29.

[0049] In the first embodiment, the first lance 35A and the second lance 35B are arranged side by side in the height direction in front of the common wall 34, and a common space portion 41 is formed in front of the first lance 35A and the second lance 35B. Therefore, compared to when the lances are formed on the outside of the common wall 34 in the width direction, the pitch between adjacent cavities 29 in the width direction can be reduced, and it is possible to prevent the housing 12 from becoming larger in the width direction.

[0050] Furthermore, since the shared space 41 is formed when the mold (not shown) that forms the front portions of the lances 35A, 35B is removed, the formability of the front portions of the lances 35A, 35B can be improved. Furthermore, the locking protrusion 18 protrudes in the height direction from the terminal body 17 and is locked to the lance protrusion 37 within the width of the lance protrusion 37. Therefore, there is little concern that the locking protrusion 18 will cause the housing 12 to become larger in the width direction.

[0051] When the housing 12 is fitted into the mating housing 73, the partitions 71 of the mating housing 73 are positioned in the shared space 41 as shown in Fig. 1. This positions the partitions 71 between the terminal fittings 11 adjacent in the width direction. Therefore, the terminal fittings 11 adjacent in the width direction are kept insulated from each other via the partitions 71. When the housing 12 and the mating housing 73 are properly fitted together, the front ends of the partitions 71 are aligned with the outer sides of the locking projections 18 in the width direction as shown in Fig. 3.

[0052] As described above, according to the first embodiment, it is possible to prevent the housing 12 from becoming large in size in the width direction, and also to maintain an insulating state between the terminal fittings 11 adjacent in the width direction.

[0053] [Another embodiment of the present disclosure] The first embodiment disclosed herein should be considered to be illustrative in all respects and not restrictive. In the first embodiment, the terminal fitting is configured as a coaxial terminal. However, in other embodiments, the terminal fitting may be a general terminal that does not have an outer conductor or a dielectric and is connected to an insulated wire that does not have a shield portion. Similarly, the mating terminal may also be a general terminal that does not have an outer conductor tube or a mating dielectric. In the first embodiment, the common space is divided into upper and lower parts by a side wall. However, in other embodiments, the common space may penetrate the side wall and be integrated. When the common space is integrated, the upper and lower partitions may also be integrated, and only one partition may be formed in the mating housing. In the first embodiment, the common wall, the lance, and the space are formed in the female connector. However, in other embodiments, the common wall, the lance, and the space may be formed in the male connector. [Explanation of symbols]
