  The conventional connector structure for connecting a seat is for a special purpose applied to a wheelchair removable seat. For example, a general user removes the seat from the floor for the purpose of widening the space in the vehicle interior. It is different from the thing.

  In this case, since the connector protrudes and remains on the floor after the seat is detached, the occupant may step on or hook the connector to break it. To prevent this, if the connector is embedded in the floor, dust or raindrops may adhere to the connector when the seat is used, which may cause power supply failure or malfunction of the seat. is there.

  Further, when the seat is not attached (when the connector is not connected), there is a concern that foreign matter such as dust or water drops may fall from the floor surface and enter the mating terminal insertion hole or the like on the front end surface of the floor side connector. Further, there is a concern that it is difficult to smoothly connect the floor side connector to the seat side connector.

  In view of the above-described points, the present invention can smoothly connect with the seat-side connector, and there is no fear of foreign matter entering the floor-side connector when the connector is not connected. It is an object of the present invention to provide a connector structure for connecting a sheet that can prevent interference with a connector on the subsequent floor side and adhesion of water droplets or the like when the connector is connected.

In order to achieve the above object, a connector structure for connecting seats according to claim 1 of the present invention is such that a floor-side connector is rotatably supported on an arm by one shaft portion, and the arm is supported by the other shaft portion. A connector structure for connecting a seat , wherein the connector on the floor side is pivotally supported, and the floor-side connector takes a horizontal posture when connected to and disconnected from the seat-side connector, The other shaft portion is rotatably supported by a slide base, and the slide base is slidable along the floor together with a seat .

With the above configuration, the floor-side connector is smoothly and reliably connected (fitted) to the seat-side connector while keeping the horizontal posture as the arm rotates during connection with the seat-side connector. Immediately before connection, the mating front end face of the floor side connector is positioned opposite to the mating front end face of the seat side connector. Also, when the connector on the floor side and the connector on the seat side are not connected, the connector mating surface of the floor side connector faces the horizontal direction, so dust and water droplets from the connector are on the floor side connector. Intrusion is prevented. When the connector is connected, the connector on the floor side is positioned so as to protrude higher than the floor surface by the arm. The connector on the floor side maintains a horizontal posture with respect to one shaft portion, for example, by contact between the stopper and the contacted portion.
Further, the floor-side connector is slid along the floor integrally with the seat while being connected to the seat-side connector. It is preferable that a guide rail for slidably engaging the slide base is provided on the floor.

  The connector structure for connecting a seat according to claim 2 is the connector structure for connecting a seat according to claim 1, wherein the floor is provided with a receiving portion for receiving the connector on the floor side, and the connector on the floor side is on the floor side. It is characterized in that it takes a horizontal posture when it is housed.

  With the above configuration, the floor side connector is horizontally accommodated in the floor side accommodating portion when not connected to the seat side connector, and the connector mating surface of the floor side connector faces the horizontal direction. Water droplets or the like are prevented from entering the connector on the floor side from the connector fitting surface. The connector on the floor side maintains a horizontal posture with respect to one shaft portion, for example, by contact between the stopper and the contacted portion.

The connector structure for connecting a seat according to claim 3 is the connector structure for connecting a seat according to claim 1 or 2 , wherein a guide rail for slidably engaging the slide base is provided and communicated with the guide rail. The housing portion is provided.

  With the above configuration, the slide base moves smoothly in the seat slide direction along the guide rail, and the floor-side connector is accommodated in the floor accommodating portion at the front end position or the rear end position of the guide rail. The guide rail and the receiving portion only need to communicate with each other along at least the pivot trajectory of the arm. The arm is also accommodated in the accommodating portion together with the floor-side connector. The guide rail preferably has a guide groove for inserting the slide guide and a slit for protruding the arm.

According to the first aspect of the invention, since the floor side connector is connected to the seat side connector in a horizontal posture, the connection is made smoothly and reliably, and the reliability of the connector connection is improved. In addition, since the floor-side connector is in a horizontal position when not connected, there is no risk of dust or water droplets from entering the floor-side connector, and the electrical connection with the seat-side connector is reliable. improves. Further, even when the seat is removed, the floor-side connector is positioned low, so that interference with passengers and the like is prevented, and the floor-side connector is safely protected. Further, when the connector is connected, the floor side connector stands up with the arm and is positioned higher than the floor, so that adhesion of water droplets or the like on the floor is prevented, and the reliability of the connector connection is improved. In addition, the power can be reliably supplied by moving the floor-side connector integrally with the seat corresponding to the sliding seat.

  According to the invention of claim 2, since the floor side connector is accommodated in the floor in a horizontal posture, the concern that dust or water droplets from above enter the floor side connector is further eliminated. The reliability of electrical connection with the side connector is further improved. Further, even when the seat is removed, the floor-side connector is accommodated in the floor, so that interference with passengers and the like can be more reliably prevented, and the floor-side connector can be more safely protected.

According to the third aspect of the present invention, the floor-side connector can be smoothly and reliably accommodated together with the arm in the accommodating portion following the guide rail.

  1 to 7 show an embodiment of a connector structure for connecting sheets according to the present invention.

  As shown in FIG. 1, a seat 1 is a slide seat of an automobile, and is slidably assembled via a slide member 4 to a pair of left and right guide rails 3 on a floor (floor) 2 of a vehicle body. The slide member 4 is locked at a desired position by a lever operation on the seat side.

  The four leg portions 5 of the sheet 1 are fixed to a substantially inverted U-shaped hook 6 of a metal slide fixing member 4 by fixing means (not shown) such as a bolt. A pair of front and rear hooks 6 are erected on a slide plate to constitute a slide member 4 that can slide in the guide rail 3.

  A seat-side connector 8 is disposed on the bottom side of the seat 1, the front end face 8a of the connector 8 faces forward, and a harness portion (a plurality of wires) 9 led out from the connector 8 is, for example, a reclining motor It is connected to seat-side auxiliary machines (not shown) such as a motor for raising and lowering, a switch for controlling them and a weight sensor. At least the connector 8 and the harness portion 9 constitute a wire harness.

  On the floor 2, a floor side connector 77 is slidably disposed along a straight long groove-shaped third guide rail 81 between the pair of left and right guide rails 3. A floor wire harness (not shown) is connected to a power source or the like. Each guide rail 3, 81 is preferably formed separately from the floor 2 and fixed to the floor 2 with a metal material, a synthetic resin material, or the like. The connector receiving groove 82 may be formed integrally with the end of the guide rail 81.

  Before the seat 1 is mounted, the floor-side connector 77 is accommodated in an accommodation groove (accommodating portion) 82 following the front end side of the third guide rail 81 on the floor 2 to prevent interference with passengers and the like. Yes. When the seat 1 is mounted, the floor side connector 77 is raised and connected to the seat side connector 8.

  The floor-side connector 77 is rotatably supported by an arm 78, and is rotatable so as to always maintain a horizontal posture with respect to the arm 78. The mating front end surface 77a of the floor-side connector 77 is provided. The arm 78 always faces the seat slide direction (rear side of the vehicle in this example) in the standing state (when the connector is connected) and the collapsed state (when the connector is not connected).

  As shown in FIG. 2, the third guide rail 81 of the floor 2 communicates with a guide groove 76 in the seat slide direction covered with the upper wall 73, and the arm 78 of the connector 77 on the floor side is in the guide groove 76. A lower horizontal shaft 79 and a horizontal slide base 80 continuing on the same surface are slidably accommodated, an arm 78 projects upward from a slit-like opening 75 on the upper side of the guide rail 81, and a connector 77 is an arm. A rectangular connector receiving groove 82 is formed so as to protrude from the floor 2 at the upper end side of 78 and has an upper opening 82 a at the end of the guide rail 81. As shown in FIG. 4, the floor side connector 77 can be accommodated horizontally in the connector accommodation groove 82 and the fitting front end surface 77a can be accommodated in the horizontal direction (backward).

  As shown in FIGS. 3 and 4 (a side view reversed from front and rear in FIG. 3), the floor-side connector 77 is in an upright state. A shaft portion 79 is rotatably connected to the other end portion (upper end portion) of the arm 78, and a floor side connector 77 is rotatably connected to a horizontal second shaft portion 83. The slide base 80, the arm 78, and the two shaft portions 79 and 83 form a connector moving mechanism, and the connector moving structure and the floor side connector 77 constitute a connector assembly structure 74. The first and second shaft portions are merely for convenience of explanation.

  The slide base 80 is formed in a substantially L shape by a front long portion 80a and a short portion 80b on one side orthogonal to the long portion 80a, and a first shaft portion 79 is orthogonal to the short portion 80b. In addition, an arm 78 positioned parallel to (in parallel with) the elongated portion 80a and perpendicular to the first shaft portion 79 is rotatably provided in the front-rear direction.

  More specifically, the arm 78 of this example is formed in a substantially U shape integrally including a vertical arm main body (substitute with reference numeral 78) orthogonal to the upper and lower horizontal and parallel shafts 83 and 79. The shaft main portions 79a and 83a are inserted into the shaft portions 79 and 83, and the slide base 80 and the floor side connector 77 are rotatably connected to the shaft portions 79 and 83 by the shaft main portions 79a and 83a. ing.

  For example, a stopper (not shown) that keeps the connector 77 in a horizontal position is provided on the upper shaft main part 83a, and a contacted part (not shown) that abuts the stopper on the connector housing (substitute with reference numeral 77). ) Is provided. It is also possible to provide a stopper (not shown) that defines the standing angle of the arm 78 at a right angle or more on the lower shaft portion 79. Further, in order to prevent the floor-side connector 77 from tilting in the vertical direction, it is possible to urge the floor-side connector 77 to always take a horizontal posture by an elastic member (not shown) such as a spring. is there.

  The connector moving mechanism in FIG. 3 is merely an example. For example, the slide base 80 is not L-shaped but is substantially U-shaped including the lower shaft portion 79, and the arm 78 is not U-shaped but upper-shaped. The upper shaft portion (83) may be directly connected to the side surface of the connector housing (77) by removing the notch 77b on the rear end side of the connector housing (77) by removing the notch 77b on the connector housing (77). The slide base 80 may be plate-shaped instead of L-shaped or U-shaped, and the lower end portion of the arm 78 may be directly connected to the side surface of the plate-shaped slide base by the lower shaft portion (79). .

  As shown in FIG. 4, the slide base 80 and the lower shaft portion 79 are always accommodated in the guide groove 76 in the guide rail 81 of the floor 2, and the center of the lower shaft portion 79 is in the height direction of the slide base 80. It substantially coincides with the center and substantially coincides with the center of the guide groove 76 in the height direction. The height of the guide groove 76 is set to be larger than the plate thickness in the front-rear direction of the arm 78 in the standing state and the thickness in the height direction of the floor side connector 77. As indicated by an arrow A, the sliding direction of the slide base 80 coincides with the fitting direction of the floor side connector 77 with respect to the seat side connector 8 (FIG. 1).

  The floor-side connector 77 and the seat-side connector 8 (FIG. 1) are connected to the floor-side connector by, for example, manually mounting the seat 1 on the floor 2 and then manually facing the seat-side connector 8. This is done by pushing the rear end of 77 (the end on the electric wire outlet side). At this time, since the slide operating force is directly transmitted to the slide base 80 with the lower shaft portion 79 as a fulcrum, a vertical and vertical twisting force does not act on the slide base 80, and a smooth and reliable connector connection (fitting) is achieved. It becomes possible.

  For example, as shown in FIG. 5, when the lower shaft portion 79 is removed, when the floor side connector 77 is pressed as shown by the arrow B, a moment M acts on the arm 78, and the slide integrated with the arm 78 is performed. A twisting force acts on the base 80 to increase the sliding friction with the guide rail 81, and there is a concern that a smooth sliding operation cannot be performed. According to the configuration of FIG. 4, such anxiety is eliminated.

  Further, as shown in FIG. 4, when the connector is fitted, the floor side connector 77 is always in a parallel posture from when it is tilted (when not connected) to when it is raised (when connected) (with the mating front end face 77a in the connector fitting direction). Therefore, the connector 8 fixed to the seat 1 can be fitted and connected smoothly and reliably.

  Further, when the seat 1 is mounted (when the connector is connected), the arm 78 stands up and the floor-side connector 77 is positioned higher than the floor surface 2, so that no water droplets or the like adhere to both the connectors 8 and 77. Concerns such as poor power feeding to the sheet 1 due to water droplets and the like and malfunction of the connector circuit are eliminated.

  As shown in FIGS. 6 and 7, when the seat 1 is detached or the connector is not connected, the arm 78 is tilted horizontally and completely accommodated in the accommodation groove 82 together with the connector 77. By pushing the floor side connector 77 or the arm 78 in the connector disengagement direction (the direction opposite to the arrow A in FIG. 4) from the standing state of the arm 78 in FIG. 3, the arm 78 falls on the lower shaft portion 79 as a fulcrum. While rotating in the direction, the floor-side connector 77 rotates in the falling direction while maintaining a horizontal posture with the upper shaft portion 83 as a fulcrum, so that the accommodation posture of FIG. 7 is obtained.

  Since the front end face 77a of the connector 77 on the floor side is accommodated in a state where it faces sideways (rear) rather than up, even if the upper opening of the connector accommodation groove 82 is always open, dust, water droplets and foreign matter are seen from above. Etc. do not enter the terminal insertion hole of the front end face 77a of the connector 77 and the reliability of the electrical connection between the connectors 77 and 8 is improved.

  Further, when the seat 1 is detached, the floor side connector 77 is accommodated in the accommodation groove 82 of the floor 2 together with the arm 78, so that the floor side connector 77 does not interfere with passengers and the like, and the connector 77 is damaged. Is prevented.

  The floor-side connector 77 accommodates female terminals with electric wires in a connector housing made of synthetic resin, and has a mating terminal insertion hole 77c opposite to the tip of the female terminal. From the viewpoint of sex. In that case, the sheet-side connector 8 has a plurality of male terminal tabs protruding from an insulating resin connector housing having a connector fitting chamber.

  In the above embodiment, the position of the connector receiving groove 82 corresponds to the position of the slide front end of the seat 1 so that the connectors 8 and 77 can be fitted and detached while the seat 1 is slid to the front end position. (The seat 1 is unlikely to be used at the foremost position of the slide), but the housing groove 82 is formed not on the front end side of the guide rail 81 but on the rear end side, or in the longitudinal direction of the guide rail 81 It is also possible to form in the middle part.

  Further, a guide rail of a harness protector (not shown) in the longitudinal direction of the vehicle is used as the third guide rail 81, and the floor side wire harness is bent from a substantially U shape to a J shape in the harness protector so as to be stretchable. It is also possible to accommodate and fix the slide base 80 to the movable end of the wire harness so as to be slidable in the longitudinal direction of the vehicle along the guide rail.

  Further, the fitting operation of both the connectors 8 and 77, that is, the turning operation of the arm 78 may be performed manually by the user as described above, but the seat 1 can be attached and detached using a cam mechanism, a gear mechanism, a lever mechanism or the like. At the same time, the lower shaft portion 79 can be rotated integrally with the arm 78 so that the connectors 8 and 77 can be automatically fitted and detached.

  Moreover, in the said embodiment, it is also possible to make the both connectors 8 and 77 into an elastic contact type instead of a fitting type. In this case, the elastic contact piece of the terminal of one connector is exposed to the front end face of the fitting, and the two connectors are electrically connected by elastically making surface contact with the terminal of the other connector.

  In the above-described embodiment, the slide base 80 is slidably engaged with the guide rail 81 corresponding to the slide type seat 1. However, in the case of a fixed type seat, for example, the slide base 80 is eliminated and the connector is removed. The arm 78 can be rotatably supported by the lower shaft portion 79 adjacent to the receiving groove 82, and the floor side connector 77 can be rotatably supported by the upper shaft portion 83 with respect to the arm 78. It is.

  Further, in the above embodiment, the floor side connector 77 is always rotated in the same horizontal posture when the arm 78 is rotated by contact of a stopper and a contacted portion (not shown) with respect to the upper shaft portion 83 in particular. However, for example, the floor side connector 77 takes the same horizontal position when the connector is fitted and when the connector is accommodated, and the arm 78 is rotated in a posture inclined upward or downward rather than horizontal during rotation. Even if it moves, there is no problem in practical use.

  In the above embodiment, the floor side connector 77 is accommodated in the connector accommodation groove 82 of the floor 2 when not connected. However, for example, the connector accommodation groove 82 is eliminated, and the floor side connector 77 is disconnected when the floor surface connector 77 is not connected. It is also possible to arrange the two horizontally. In this case, the lower half side of the arm 78 may be accommodated in the floor. Even if the floor-side connector 77 is not housed in the connector housing groove 82, the front-side end face 77a of the floor-side connector 77 faces in the horizontal direction, so that the front-side end face 77a (inside the connector 77) is fitted from above. Intrusion of dust and water droplets is prevented.

  The configuration of the above embodiment can also be applied to seats of vehicles other than automobiles, seats other than vehicles, and the like. It is also possible to use another slide structure instead of the sheet. Sliding seats are also collectively referred to as slide structures.
