DETAILED DESCRIPTION TO EXECUTE THE INVENTION
Description of Embodiments of Present Disclosure
First, embodiments of the present disclosure are listed and described.
- (1) The connector device of the present disclosure is provided with a connector and a mating connector connectable to the connector from front, the mating connector including a tubular receptacle, the connector including a housing having a housing body to be fit into the receptacle and a sealing member to be held in close contact with the receptacle by being mounted on an outer peripheral surface of the housing body, a protrusion for filling a gap between the housing body and the receptacle being provided on the outer peripheral surface of the housing body, and the protrusion being capable of facing and contacting the sealing member from a front side.
According to the configuration of the present disclosure, since the gap between the housing body and the receptacle of the mating connector is filled by the protrusion, rattling between the housing body and the receptacle of the mating connector is suppressed. Further, forward detachment of the sealing member from the housing body is suppressed by the protrusion contacting the sealing member from behind in a connection direction of the mating connector. Therefore, the connector device can have both a function of suppressing rattling between the housing of the connector and the receptacle of the mating connector and a function of suppressing the detachment of the sealing member by a simple configuration of providing the protrusion.
- (2) Preferably, the protrusion has a top part provided on a tip side in a projecting direction, and a curved surface continuous from a front end of the protrusions to the top part.
According to this configuration, the sealing member is less likely to be damaged when riding over the curved surface as compared to a case where a front end side of the protrusion is angular.
- (3) Preferably, the protrusion has a curved surface convex forward from the front end of the protrusion to the top part when viewed from the projecting direction.
According to this configuration, the sealing member is less likely to be damaged when contacting the front end side of the protrusion as compared to a case where the front end side of the protrusion is angular when viewed from the projecting direction.
- (4) Preferably, the protrusion has an inclined surface approaching the housing body from the top part toward a rear side.
According to this configuration, the deformation of the sealing member riding over the inclined surface can be gently restored.
- (5) Preferably, a rear end surface of the protrusion is disposed along the projecting direction of the protrusion from the housing body.
According to this configuration, the rear end surface of the protrusion more easily interferes with the sealing member in a front-rear direction and the sealing member is more easily stopped to prevent any further forward movement by the rear end surface of the protrusion as compared to a configuration in which the rear end surface of the protrusion is inclined to the projecting direction of the protrusion.
- (6) Preferably, the rear end surface of the protrusion is a curved surface convex rearward when viewed from the projecting direction of the protrusion.
According to this configuration, the sealing member is less likely to be damaged when contacting the rear end surface of the protrusion from the rear side as compared to a configuration in which the rear end of the protrusion is angular when viewed form the projecting direction.

(Configuration of Connector)
As shown in FIG. 2, the connector 20 is provided with a housing 40, a retainer 50, a sealing member 60 and the terminal fittings 70.
The housing 40 is made of synthetic resin. The housing 40 is connectable to the mating housing 31 of the mating connector 30. As shown in FIG. 2, the housing 40 includes a housing body 41 and an outer tube portion 42.

As shown in FIGS. 2 and 10, the housing body 41 is provided with a plurality of (six in the first embodiment) cavities 43 for accommodating the terminal fittings 70. The plurality of cavities 43 are disposed in parallel in the width direction (lateral direction). As shown in FIG. 10, the cavity 43 is formed to penetrate through the housing body 41 in the front-rear direction. A cantilevered locking lance 44 is provided inside the cavity 43. The locking lance 44 is deflectable and deformable and can retain the terminal fitting 70 by resiliently locking the terminal fitting 70.
As shown in FIGS. 1 and 5, the lock arm 45 is provided on the upper surface of the housing body 41. As shown in FIG. 9, the lock arm 45 locks a connected state when the both connectors 20, 30 are connected. As shown in FIG. 1, the lock arm 45 includes a pair of arms 46 extending along the front-rear direction. The pair of arms 46 are respectively coupled to side walls 47 on both left and right sides provided on the upper surface of the housing body 41. Although not shown, the arm 46 is coupled to the side wall 47 at a position near a rear part in the front-rear direction. In this way, the lock arm 45 can be swingably displaced in the vertical direction with a part coupled to the side wall 47 as a center. The front ends of the both arms 46 are coupled by a lock portion 48 (see FIG. 4). As shown in FIG. 9, the lock portion 48 is locked to the receiving portion 35. The rear ends of the both arms 46 are coupled by an operating portion 49. By pressing the operating portion 49, a locked state of the respective connectors 20, 30 can be released.
As shown in FIG. 3, the outer tube portion 42 is provided with the first groove 42A and a pair of the second grooves 42B. The first groove 42A is recessed upward from an upper part of the inner surface of the outer tube portion 42. The pair of second grooves 42B are respectively recessed laterally outward from both left and right parts of the inner surface of the outer tube portion 42. The first and second grooves 42A, 42B are disposed along the front-rear direction. The first and second grooves 42A, 42B respectively guide the first projections 36 and the second projections 37 of the mating connector 30 at the time of connecting the respective connectors 20, 30.
As shown in FIG. 5, the housing body 41 and the outer tube portion 42 are connected via a rear wall 40A. The rear wall 40A is disposed along the vertical direction from the rear end of the housing body 41 to the rear end of the outer tube portion 42. As shown in FIG. 8, recesses 40B recessed rearward are provided at four positions corresponding to protruding portions 62 of the sealing member 60 to be described later on the front surface of the rear wall 40A.
The retainer 50 is assembled with the housing body 41 from front. As shown in FIG. 2, the retainer 50 includes a body portion 51, first supporting portions 52, front stop portions 53 and second supporting portions 54. The first supporting portions 52, the front stop portions 53 and the second supporting portions 54 are provided to correspond to the respective cavities 43. The body portion 51 is in the form of a plate long in the width direction (lateral direction). The first supporting portion 52 projects upward from the body portion 51. The front stop portion 53 projects upward from the front end of the first supporting portion 52. The second supporting portion 54 is provided behind the first supporting portion 52 in the body portion 51. The second supporting portion 54 is recessed downward from the upper surface of the body portion 51. As shown in FIG. 10, the first supporting portion 52 supports a box portion 71 of the terminal fitting 70 from below. The second supporting portion 54 restricts the deflection and deformation of the locking lance 44 by contacting the locking lance 44 from below. The front stop portion 53 stops the terminal fitting 70 to prevent any further forward movement by contacting the box portion 71 from front.
By assembling the retainer 50 with the housing 40, six tab insertion holes 55 for stopping the terminal fittings 70 to prevent any further forward movements and allowing the entrance of the respective mating terminal fittings 32 are open in parallel in the width direction (lateral direction) as shown in FIG. 3.
As shown in FIG. 2, the sealing member 60 is in the form of a ring long in the width direction (lateral direction). The sealing member 60 is mounted on the outer peripheral surface of the housing body 41. The sealing member 60 includes a sealing body 61 and four protruding portions 62. The sealing body 61 is in the form of a ring long in the width direction (lateral direction). The four protruding portions 62 respectively protrude from four corner parts of the sealing body 61. As shown in FIG. 9, with the connection of the respective connectors 20, 30 completed, the sealing member 60 is disposed between the outer peripheral surface of the housing body 41 and the inner peripheral surface of the receptacle 33. The sealing member 60 is held in close contact with the housing body 41 and the receptacle 33 to seal between the respective connectors 20 and 30.
The sealing member 60 is fit to the housing body 41 from front, rides over protrusions 90 to be described later and is disposed on a rear end side of the outer peripheral surface of the housing body 41. As shown in FIG. 8, the sealing member 60 is stopped to prevent any further rearward movement by the front surface of the rear wall 40A of the housing 40. The protruding portions 62 of the sealing member 60 enter the recesses 40B of the rear wall 40A.
As shown in FIGS. 2 and 10, the terminal fitting 70 has a shape elongated in the front-rear direction as a whole. As shown in FIG. 10, the terminal fitting 70 includes the box portion 71 and a crimping portion 72. The box portion 71 constitutes a front part of the terminal fitting 70. The box portion 71 is in the form of a rectangular tube. The crimping portion 72 is in the form of an open barrel. The crimping portion 72 is crimped and connected to a sealing rubber plug 74 fit on an end of a wire 73. The wire 73 is pulled out rearward of the housing body 41 from the cavity 43.
(Configuration of Protrusion)
As shown in FIGS. 3 and 4, four protrusions 90 are provided on the outer peripheral surface (upper, lower and both left and right surfaces) of the housing body 41. The upper and lower protrusions 90 are provided in a center in the width direction (lateral direction) of the housing body 41 and slightly behind the front end of the housing body 41 in the front-rear direction. The left and right protrusions 90 are provided at positions below a center in the vertical direction. The protrusion 90 has a shape elongated in the front-rear direction. As shown in FIGS. 9 to 11, the protrusions 90 fill a gap between the housing body 41 and the receptacle 33. Thus, rattling between the housing 40 and the mating housing 31 is suppressed. In this way, rattling between the terminal fittings 70 and the mating terminal fittings 32 is suppressed.
The protrusions 90 can face and contact the sealing member 60 from the front side. Thus, forward detachment of the sealing member 60 from the housing body 41 is suppressed. Therefore, the connector 20 can have both a function of suppressing rattling between the housing 40 and the mating housing 31 and a function of suppressing the detachment of the sealing member 60 by a simple configuration of providing the protrusions 90.
Although the upper protrusion 90 of the housing body 41 shown in FIG. 6 is described below, the other three protrusions 90 are also similarly configured.
As shown in FIGS. 3 and 4, the upper surface of the protrusion 90 is a curved surface convex upward when viewed from the front-rear direction. That is, an upper end appearing in a cross-section when the protrusion 90 is cut by an arbitrary plane orthogonal to the front-rear direction has an arc shape convex upward.
As shown in FIG. 6, a top part 91 is provided on a tip side of the protrusion 90 in a projecting direction (vertical direction). The top part 91 is provided at a position near a front side in the front-rear direction in the protrusion 90. The upper surface (top surface) of the top part 91 is disposed along the front-rear direction. The upper surface of the top part 91 is a curved surface convex upward when viewed from the front-rear direction.
As shown in FIG. 6, the protrusion 90 has a curved surface 93 continuous from a front end 92 to the top part 91. The curved surface 93 is the front surface (surface facing forward) of the protrusion 90. The curved surface 93 is arc-shaped when viewed from the width direction (lateral direction). By such a configuration, the sealing member 60 is less likely to be damaged when riding over the curved surface 93 as compared to a configuration in which the side of the front end 92 of the protrusion 90 is angular.
A rising angle α of the curved surface 93 shown in FIG. 6 is an angle between the upper edge of the housing body 41 and the upper edge of the base end of the curved surface 93 appearing when viewed from the width direction (lateral direction). That is, the angle α is an acute angle formed by a direction parallel to the upper edge of the housing body 41 and a tangential direction to the upper edge of the base end of the curved surface 93 when viewed from the width direction (lateral direction). The angle α is preferably 30° or more and 60° or less, more preferably 40° or more and 50° or less, and even more preferably 45°.
As shown in FIG. 7, the curved surface 93 is also a curved surface convex forward from the front end 92 to the top part 91 when viewed from the projecting direction (vertical direction). That is, a front edge appearing in a cross-section when the curved surface 93 is cut by an arbitrary plane orthogonal to the vertical direction has an arc shape convex forward. In this way, the sealing member 60 is less likely to be damaged when contacting the side of the front end 92 of the protrusion 90 as compared to a configuration in which the side of the front end 92 of the protrusion 90 is angular when viewed from the projecting direction (vertical direction).
As shown in FIG. 6, the protrusion 90 has an inclined surface 95 on the side of a rear end 94. The inclined surface 95 is continuous rearward from the top part 91 and inclined to approach the housing body 41 toward a rear side. The inclined surface 95 is continuous from the top part 91 to the rear end 94. The inclined surface 95 is also a surface convex upward when viewed from the front-rear direction. Thus, the deformation of the sealing member 60 riding over the inclined surface 95 can be gently restored.
An angle of inclination β of the inclined surface 95 shown in FIG. 6 is an angle formed between the upper edge of the housing body 41 and the upper edge of the inclined surface 95 appearing when viewed from the width direction (lateral direction). The angle β is smaller than the angle α. The angle β is preferably 5° or more and 45° or less, more preferably 8° or more and 30° or less, and even more preferably 10° or more and 20° or less.
As shown in FIG. 6, a rear end surface 96 of the protrusion 90 is disposed along the projecting direction (vertical direction) of the protrusion 90 from the housing body 41. Thus, the rear end surface 96 of the protrusion 90 more easily interferes with the sealing member 60 in the front-rear direction and the sealing member 60 is more easily stopped to prevent any further forward movement by the rear end surface 96 as compared to a configuration in which the rear end surface 96 of the protrusion 90 is inclined to the projecting direction (vertical direction).
As shown in FIG. 7, the rear end surface 96 of the protrusion 90 is a curved surface convex rearward when viewed from the projecting direction (vertical direction) of the protrusion 90. Thus, the sealing member 60 is less likely to be damaged when contacting the rear end surface 96 of the protrusion 90 from behind as compared to a configuration in which the rear end 94 of the protrusion 90 is angular when viewed from the projecting direction (vertical direction).
As shown in FIG. 6, if L1 denotes a length in the front-rear direction of the protrusion 90, the top part 91 is located within a half distance range of L1 behind the front end 92. Further, if L2 denotes a projecting length of the protrusion 90 from the outer peripheral surface of the housing body 41 (distance between the outer peripheral surface of the housing body 41 and the top surface of the top part 91) and L3 denotes a length in the projecting direction (vertical direction) of the rear end 94, L2 is about twice as large as L3.
Effects of First Embodiment
In the connector device 10 of the first embodiment, the protrusions 90 for filling the gap between the housing body 41 and the receptacle 33 are provided on the outer peripheral surface of the housing body 41. The protrusions 90 can face and contact the sealing member 60. According to this configuration, since the gap between the housing body 41 and the receptacle 33 is filled by the protrusions 90, rattling between the housing 40 and the receptacle 33 is suppressed. Further, the protrusions 90 contact the sealing member 60 from behind in the connection direction of the mating connector 30, whereby forward detachment of the sealing member 60 from the housing body 41 is suppressed. Therefore, the connector device 10 can have both the function of suppressing rattling between the housing 40 and the mating housing 31 and the function of suppressing the detachment of the sealing member 60 by the simple configuration of providing the protrusions 90.
Further, the protrusion 90 includes the top part 91 provided on the tip side in the projecting direction and the curved surface 93 continuous from the front end 92 to the top part 91. In this way, the sealing member 60 is less likely to be damaged when riding over the curved surface 93 as compared to the configuration in which the side of the front end 92 of the protrusion 90 is angular.
Further, the protrusion 90 has the curved surface 93 convex forward from the front end 92 to the top part 91 when viewed from the projecting direction. In this way, the sealing member 60 is less likely to be damaged when contacting the side of the front end 92 of the protrusion 90 as compared to the configuration in which the side of the front end 92 of the protrusion 90 is angular when viewed from the projecting direction.
Further, the protrusion 90 has the inclined surface 95 approaching the housing body 41 from the top part 91 toward the rear side. In this way, the deformation of the sealing member 60 riding over the inclined surface 95 can be gently restored.
Further, the rear end surface 96 of the protrusion 90 is disposed along the projecting direction of the protrusion 90 from the housing body 41. In this way, the rear end surface 96 of the protrusion 90 more easily interferes with the sealing member 60 in the front-rear direction and the sealing member 60 is more easily stopped to prevent any further forward movement by the rear end surface 96 as compared to the configuration in which the rear end surface 96 of the protrusion 90 is inclined to the projecting direction of the protrusion 90.
Further, the rear end surface 96 of the protrusion 90 is a curved surface convex rearward when viewed from the projecting direction of the protrusion 90. In this way, the sealing member 60 is less likely to be damaged when contacting the rear end surface 96 of the protrusion 90 from behind as compared to the configuration in which the rear end of the protrusion 90 is angular when viewed from the projecting direction.

The connector 220 includes one terminal fitting 270.
As shown in FIG. 13, a protrusion 290, a protrusion 390, a protrusion 490 and a protrusion 490 are respectively provided on the upper, lower, left and right surfaces of a housing body 241. The protrusions 290, 390 and 490 fill a gap between the housing body 241 and a receptacle 233. The protrusions 290, 390 and 490 can face and contact the sealing member 260 from front. The upper surface of the protrusion 290 is a curved surface convex upward when viewed from the front-rear direction. As shown in FIG. 14, a rear part of the protrusion 290 serves as a top part 291. The upper surface (top surface) of the top part 291 is disposed along the front-rear direction. The upper surface of the top part 291 is a curved surface convex upward when viewed from the front-rear direction.
As shown in FIG. 15, the protrusion 290 has a curved surface 293 continuous from a front end 292 to the top part 291. The curved surface 293 is arc-shaped when viewed from the width direction (lateral direction). As shown in FIG. 14, the curved surface 293 is also a surface convex forward from the front end 292 to the top part 291 when viewed from the projecting direction (vertical direction). As shown in FIGS. 14 and 15, a rear end surface 296 of the protrusion 290 is disposed along the projecting direction (vertical direction) of the protrusion 290 from the housing body 241.
