H08-264229 and H11-144804 and European patent EP1172898 which discloses an electrical connecting device according to the preamble of claim 1).
  • the hook element when the connecting housing element is fitted into the to-be-connected housing element, the hook element operates in cooperation with the to-be-connected housing element.
  • the hook element is relatively moved to the connecting housing element so that a hooked position is changed, and thus a fitting state can be confirmed. That is, an appropriate fitting state is ensured with the operation of the hook element and therefore it is possible to confirm whether mechanical and electrical connection states are completed can be confirmed.
  • the to-be-connected housing element is required to have an exclusive shape. That is, at least a part of the shape of the to-be-connected housing element is required to have a specific shape corresponding to the hook element so that the hook element can operate in cooperation with the to-be-connected housing element.
  • the shape of the to-be-connected housing element becomes a structure exclusive for an electrical connecting device provided with a predetermined hook element, and it becomes difficult that an electrical connecting device provided with no hook element is connected to the to-be-connected housing element.
  • the electrical connecting device provided with the hook element is required to be changed so as to be applicable under an environment that a connector unit configured by the to-be-connected housing element and the electrical connecting device provided with no hook element is used, not only the electrical connecting device but also the to-be-connected housing element must be changed.
  • the electrical connecting device provided with the hook element is used in a mix with that without the hook element, a to-be-connected housing element in accordance with each shape of them is needed, and therefore there is a possibility of causing an increase in the kinds of components.
  • an object of the present invention to provide an electrical connecting device capable of significantly reducing restrictions in shape of a to-be-connected housing element regarding operation of a hook element for confirmation of fitting, and to make the to-be-connected housing element common in both cases where the electrical connecting device for connection includes the hook element and where it includes no hook element.
  • the present invention relates to an electrical connecting device that is connected to a to-be-connected housing element supporting one or more to-be-connected terminal(s). Further, the present invention has some features as described below in order to accomplish the above-described object. That is, the present invention includes only one of the features or in combination of any of the features as described below.
  • a first feature of the electrical connecting device is that the electrical connecting device includes: a connecting housing element for supporting one or more connection terminal(s) which is or are electrically connected to the to-be-connected terminal(s) and for being connected to the to-be-connected housing element by fitting; a hook element for being hooked to the connecting housing element in such a way of being inserted into the connecting housing element and locked thereto at a first position; and a slider as a member which is slidably supported in the connecting housing element and is brought into contact with a part of the to-be-connected housing element and energized to be moved toward the hook element hooked to the connecting housing element at the first position when the connecting housing element is fitted into the to-be-connected housing element, and is that the slider comes into contact with the hook element to release the locking at the first position when moved toward the hook element so that the hook element becomes movable in relation to the connecting housing element.
  • Another feature included with the first group of feature of the electrical connecting device according to the present invention is that the hook element, of which the locking to the connecting housing element at the first position is released, can be hooked to the connecting housing element at a second position deviated from the first position in the fitting direction in which the connecting housing element is fitted into the to-be-connected housing element.
  • Still another feature also included with the first group of feature of the electrical connecting device according to the present invention is that the hook element is formed so as to protrude from the connecting housing element when hooked to the connecting housing element at the first position and is formed so as not to protrude from the connecting housing element when hooked to the connecting housing element at the second position.
  • the slider is brought into contact with a part of the to-be-connected housing element and energized to be moved to the hook element side when the connecting housing element is fitted into the to-be-connected housing element. Then, the moved slider comes into contact with the hook element so that the locking at the first position is released, and therefore the hook element becomes movable in relation to the connecting housing element. Accordingly, workers can confirm a fitting state between the to-be-connected housing element and the connecting housing element by confirming the movable state of the hook element.
  • the hook element can almost be made to operate by only a mechanism of the electrical connecting device side with almost no regard for the shape of the to-be-connected housing element during the connecting operation of the connecting housing element and the to-be-connected housing element.
  • the present invention can provide the electrical connecting device capable of significantly reducing restrictions in the shape of the to-be-connected housing element regarding operation of the hook element for confirmation of fitting, and can make the to-be-connected housing element common in both cases where the electrical connecting device for connection includes the hook element and where it includes no hook element.
  • the fitting state is also possible to confirm that the fitting state is incomplete and mechanical and electrical connections are not completed when the hook element is hooked to the connecting housing element at the first position, and to confirm that the fitting state is complete and mechanical and electrical connections are completed when the hook element is hooked to the connecting housing element at the second position. That is, the fitting state can easily be confirmed by visual observation on whether the hook element is hooked to the connecting housing element at the first position or second position.
  • a second feature of the electrical connecting device is that the hook element includes a pair of cantilever-shaped elastic clamp parts for clamping an erecting part formed in the connecting housing element so as to erect in a direction perpendicular to the direction in which the hook element is inserted into the connecting housing element; and the pair of elastic clamp parts of the hook element interferes with the erecting part to be elastically deformed and then is elastically recovered to be engaged with the erecting part when the hook element is inserted into the connecting housing element, and thus the hook element is hooked to the connecting housing element at the first position.
  • a third feature of the electrical connecting device is that the slider includes a projection part protruded so as to come into contact with both front end parts of the pair of elastic clamp parts; and the projection part is energized in a direction in which the pair of elastic clamp parts are pressed and opened with the movement of the slider.
  • An fourth feature of the electrical connecting device is that the projection part is formed so as to have inclined surfaces which are formed to be inclined toward the slide moving direction in which the slider is slidably supported, and are energizing the pair of elastic clamp parts in the pressing and opening direction with the movement of the slider.
  • a fifth feature of the electrical connecting device is that the pair of elastic clamp parts are engaged with the projection part so as to clamp both the projection part and the erecting part via the elastic recovery by further movement of the slider in relation to the hook element after being pressed and opened with the movement of the slider.
  • the hook element of which the locking to the connecting housing element at the first position is released with the slider, is engaged with the projection part so as to clamp both the projection part and the erecting part with the slider. That is, the hook element, of which the locking to the connecting housing element at the first position is released, is hooked to the connecting housing element via the slider.
  • the hook element, of which the locking to the connecting housing element at the first position is released can be reliably and strongly hooked to the connecting housing element at a position different from the first position.
  • Another feature of the electrical connecting device according to the present invention is that a sliding direction of the slider slidably supported coincides with a fitting direction in which the connecting housing element is fitted into the to-be-connected housing element.
  • the slider brought into contact with a part of the to-be-connected housing element can smoothly be energized in the same direction as the fitting direction when the connecting housing element is fitted into the to-be-connected housing element. Therefore, the moving operation of the slider can smoothly be performed without interfering with the fitting operation.
  • Still another feature of the electrical connecting device according to the present invention is that a moving direction of the hook element, of which the locking to the connecting housing element at the first position is released, coincides with the fitting direction in which the connecting housing element is fitted into the to-be-connected housing element.
  • the moving operation of the hook element after the release of the locking and the fitting operation can smoothly be performed without interference with each other. Further, the moving operation of the hook element after the release of the locking and the fitting operation can be realized as a series of operations and a continuous one operation.

Accordingly, the workers can confirm the fitting state between the to-be-connected housing element 2 and the connecting housing element 12 by confirming the movable state.
  • the hook element 13 can almost be made to operate by only a mechanism of the electrical connecting device side with almost no regard for the shape of the to-be-connected housing element 2 during the connecting operation of the connecting housing element 12 and the to-be-connected housing element 2. Therefore, the present invention can provide the electrical connecting device capable of significantly reducing restrictions in shape of the to-be-connected housing element regarding operation of the hook element for confirmation of fitting, and can make the to-be-connected housing element common in both cases where the electrical connecting device for connection includes the hook element and where it includes no hook element.
  • the slider 14 brought into contact with a part of the to-be-connected housing element 2 can smoothly be energized in the same direction as the fitting direction when the connecting housing element 12 is fitted into the to-be-connected housing element 2. Therefore, the moving operation of the slider 14 can smoothly be performed without interfering with the fitting operation.
  • the moving operation of the hook element 13 after the release of the locking and the fitting operation can smoothly be performed without interference with each other. Further, the moving operation of the hook element 13 after the release of the locking and the fitting operation can be realized as a series of operations and a continuous one operation.
  • the electrical connecting device 1 it is possible to confirm that the fitting state is incomplete and mechanical and electrical connections are not completed when the hook element is hooked to the connecting housing element at the first position, and further to confirm that the fitting state is complete and mechanical and electrical connections are completed when the hook element is hooked to the connecting housing element at the second position. That is, the fitting state can easily be confirmed by visual observation on whether the hook element 13 is hooked to the connecting housing element at the first position or second position.
  • the electrical connecting device 1 it is possible to easily confirm by the visual observation that the hook element 13 is hooked to the connecting housing element 12 at the first position when protruded from the connecting housing element 12 and similarly to easily confirm by the visual observation that the hook element 13 is hooked to the connecting housing element 12 at the second position when not protruded from the connecting housing element 12. Therefore, the fitting state can easily be confirmed by the visual observation.
  • the pair of elastic clamp parts 25 and 25 is provided in the hook element 13, the erecting part 23 is provided in the connecting housing element 12 and the hook element 13 is inserted into the connecting housing element 12, so that a configuration in which the hook element is hooked to the connecting housing element at the first position can easily be realized with a simple mechanism.
  • the protrusion 29, of which the inclined surfaces 29a are formed is formed on the slider 14, and thus a configuration, in which the pair of elastic clamp parts 25 and 25 are pressed and opened so that the slider 14 is brought into contact with the hook element 13 to release the locking at the first position when moved toward the hook element 13 with the fitting operation, can easily be realized with the simple mechanism.
