Title: Connector with aligning plate

Description:
BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   The present invention relates to a connector provided with an aligning plate for supporting male terminals and for positioning the male terminals to prescribed positions. 
   2. Related Art 
   As a connector for electrically connecting electric wires which are arranged in a vehicle or the like, there are a so-called male connector and a female connector. Each of the connectors includes a connector housing, and terminals which are contained in the connector housing. The aforesaid female connector includes the connector housing having an engaging space for receiving the male connector and the terminals of male type (hereinafter referred to as male terminals). Base ends of these male terminals are mounted to the terminal container of the connector housing, and electric connecting portions extended from the base ends are positioned in the engaging space. 
   The electric connecting portions of the male terminals of the female connector are likely to be crooked, because they have a shape of an elongated rod, and there is a problem that positional deviation may occur with respect to the terminals of female type (hereinafter referred to as female terminals) which are contained in the mating male connector. In order to solve such a problem, there has been employed a female connector which is provided with an aligning plate (also called as a moving plate) for positioning the electric connecting portions of the male terminals at the prescribed positions, as shown in  FIG. 5  (see JP-A-2002-343483 and JP-A-2006-253074, for example). 
   A female connector  101  which is shown in  FIG. 5  includes a connector housing  104  having an engaging space  140  for receiving a mating male connector  102  along an inserting direction K and a terminal container  144  which is positioned at a deeper side than the engaging space  140  in the inserting direction K, a plurality of male terminals  105  having base ends mounted to the terminal container  144  and electric connecting portions positioned in the engaging space  140 , and an aligning plate  103  which is formed separately from the connector housing  104  and provided so as to move in the engaging space  140 . 
   The aligning plate  103  includes a plate part  130  having terminal insertion holes through which the electric connecting portions of the male terminals  105  are adapted to pass, and a pair of permanently locking arms  132  which are respectively extended from both ends of the plate part  130  in a longitudinal direction L. 
   Before the female connector  101  is engaged with the male connector  102 , the aligning plate  103  stays at a temporarily locked position as shown by a solid line in  FIG. 5 , and respective surfaces  130   a  in both longitudinal end parts of the plate part  130  along the longitudinal direction L at a side facing the terminal container  144  are butted against temporarily locking hooks  106  which are provided on inner walls  141  defining the engaging space  140 , whereby the aligning plate  103  is held by the temporarily locking hooks  106 . In this manner, the aligning plate  103  is prevented from moving to the deep side, that is, toward the terminal container  144 , unless the male connector  102  is inserted into the engaging space  140 . 
   Moreover, when the male connector  102  is inserted into the engaging space  140  and the aligning plate  103  is pressed with this male connector  102  toward the terminal container  144 , the temporarily locking hooks  106  are flexed outward of the engaging space  140  to be unlocked from the surfaces  130   a , whereby the aligning plate  103  is moved to a permanently locked position which is shown by a one-dot chain line in  FIG. 5 . Then, a pair of the permanently locking arms  132  of the aligning plate  103  are locked to permanently locking locks  142  which are provided at a deeper side than the engaging space  140  in the connector housing  140 , whereby the aligning plate  103  is fixed at the permanently locked position. 
   However, there are the following problems to be solved, in the female connector  101  provided with the above described known aligning plate  103 . Specifically, on such an occasion that the female connector  101  is transported, in a state where the male terminals  105  are contained in the connector housing  104 , the aligning plate  103  is inadvertently moved from the temporarily locked position to the permanently locked position at the deeper side, in some cases. More specifically, in case where a hand of a worker or a connector different from the mating connector is inserted into the engaging space  140  of the female connector  101 , the plate part  130  of the aligning plate  103  is forcibly pressed to the deeper side, and the surfaces  130   a  are unlocked from the temporarily locking hooks  106 , whereby the aligning plate  103  is moved from the temporarily locked position to the permanently locked position, in some cases. 
   This phenomenon is attributed to a holding structure of the aligning plate  103  by means of the temporarily locking hooks  106 . Specifically, as shown in  FIG. 6A , each of the temporarily locking hooks  106  is continued from the inner wall  141  as shown in  FIG. 5 , and composed of an arm portion  161  which extends toward the terminal container  144  in the inserting direction K, and a projection  163  which is projected from an end of the arm portion  161  remote from the inner wall  141  and adapted to be overlapped on the surface  130   a  of the aligning plate  103 . When the plate part  130  is pressed toward the terminal container  144 , the arm portion  161  of the temporarily locking hook  106  is flexed outward of the engaging space  140 , and the surface  130   a  becomes less overlapped on the projection  163 , as shown in  FIG. 6B . As the results, the projection  163  is easily detached from the surface  130   a , as shown in  FIG. 6C . 
   In case where the aligning plate  103  has moved to the deeper side and is not at the temporarily locked position, the electric connecting portions of the male terminals  105  are made free, and easily deformed with interference of the hand of the worker or the connector different from the mating connector. Even though the male terminals  105  are not interfered with the hand of the worker or the connector different from the mating connector, the electric connecting portions of the male terminals  105  may sway, since they are not positioned by the aligning plate  103 , and there is such anxiety that the male terminals  105  may not be properly engaged with the female terminals. 
   SUMMARY OF THE INVENTION 
   Under the circumstances, this invention has been made in view of the above described problems, and it is an object of the invention to provide a connector with an aligning plate in which the aligning plate can be reliably held at a temporarily locked position. 
   In order to attain the above described object, there is provided a connector including: 
   a connector housing having an inner wall; 
   an engaging space which is provided in the connector housing, and has an entrance to receive a mating connector through the entrance; 
   a terminal container which is provided in the connector housing to be opposed to the entrance of the engaging space; 
   a male terminal including a base end fitted to the terminal container and an electric connecting portion extended from the base end into the engaging space; 
   an aligning plate which is arranged within the engaging space, is provided with a terminal insertion hole for passing the electric connecting portion therethrough, and is adapted to move in the engaging space between a temporarily locked position and a permanently locked position, the temporarily locked position representing a position in which the terminal insertion hole is positioned at one end part of the electric connecting portion remote from the base end prior to engagement of the mating connector, and the permanently locked position representing a position in which the terminal insertion hole is positioned at the other end part of the electric connecting portion close to the base end after the engagement of the mating connector; 
   a temporarily locking hook including: an arm portion which is extended from the inner wall toward the terminal container and positioned outside of the aligning plate; and a projection which is projected from an end of the arm portion remote from the inner wall and adapted to be bufted against a surface of the aligning plate at a side facing the terminal container so as to hold the aligning plate at the temporarily locked position; and a contact part provided on the projection to contact the aligning plate, so that a vector for pulling the arm portion inward into the engaging space is generated when the aligning plate is pressed toward the terminal container. 
   In the above-mentioned connector, the aligning plate may include a dent in a concave shape, and the contact part may be brought into contact with an inner face of the dent. 
   In the above-mentioned connector, the contact part may be brought into line contact with the aligning plate. 
   In the above-mentioned connector, the arm portion may be curved in a direction toward a center of the engaging space as the arm portion goes toward the terminal container, in a state where a pressure is not applied to the arm portion. 
   In the above-mentioned connector, the aligning plate may include a shearing part which has a smaller thickness than other parts of the aligning plate, and is adapted to be sheared when the aligning plate is pressed toward the terminal container with a force exceeding a limit value of stress thereof. 
   According to the above configurations, the temporarily locking hook is provided to include: an arm portion which is extended from the inner wall toward the terminal container and positioned outside of the aligning plate; and a projection which is projected from an end of the arm portion remote from the inner wall and adapted to be butted against a surface of the aligning plate at a side facing the terminal container so as to hold the aligning plate at the temporarily locked position, and a contact part is provided on the projection to contact the aligning plate, so that a vector for pulling the arm portion inward into the engaging space is generated when the aligning plate is pressed toward the terminal container. 
   Therefore, when the aligning plate is forcibly pressed toward the terminal container by a worker&#39;s hand or another connector different from the mating connector to be engaged, the arm portion of the temporarily locking hook is pulled inward into the engaging space to be flexed inwardly. Accordingly, decrease of an overlapping amount between the projection and the surface of the aligning plate is eliminated, and hence, the aligning plate is prevented from moving toward the terminal container across this projection. As the results, the aligning plate is prevented from moving toward the terminal container, unless the aligning plate is pressed with engaging action of the mating connector. In this manner, it is possible to provide the connector with the aligning plate in which the aligning plate can be reliably held at the temporarily locked position. 
   According to the above configurations, the dent in a concave shape is formed in the aligning plate, and the inner face of the dent is brought into contact with the contact part. Therefore, it is possible to increase the overlapping amount between the projection and the surface of the aligning plate, without increasing a thickness of the aligning plate. Moreover, it is also possible to make an inclination angle of a part of the inner face of the dent to be butted against the contact part acute with respect to a direction of the surface of the aligning plate, without increasing the thickness of the aligning plate. 
   According to the above configurations, the contact part is so provided as to be brought into line contact with the aligning plate, and therefore, it becomes easy to make the vector generated in the contact part directed so as to approach a center of the engaging space. 
   According to the above configurations, the arm portion is curved in a direction toward the center of the engaging space as it goes toward the terminal container, in a state where a pressure is not applied to the arm portion. Therefore, an inclination angle of a taper face of the projection can be made acute with respect to the direction of the surface of the aligning plate, and the vector generated in the contact part which is positioned on the taper face can be easily directed so as to approach the center of the engaging space. Moreover, when a pressure is applied to the projection, the arm portion is elastically deformed from the curved shape to a rectilinear shape, and hence, decrease of the overlapping amount between the projection and the surface of the aligning plate is eliminated. 
   According to the above configurations, the aligning plate includes the shearing part which has a smaller thickness than other parts of the aligning plate, and is adapted to be sheared when the aligning plate is pressed toward the terminal container with a force exceeding a limit value of stress thereof. Therefore, it is possible to prevent the temporarily locking hook from being broken, and the connector housing can be re-used, by exchanging the aligning plate which has been broken.

   As shown in  FIG. 1 , a connector  1  according to the embodiment of this invention includes a connector housing  4 , a plurality of male terminals  5 , and an aligning plate  3 . 
   The connector housing  4  is formed of insulating synthetic resin, and has an engaging space  40  for receiving a male connector  2  as a mating connector along an inserting direction K, and a terminal container  44  which is arranged at a deeper side than this engaging space  40  in the inserting direction K. Moreover, a pair of inner walls  41  opposed to each other, out of the inner walls defining the engaging space  40 , are respectively provided with two (four in total) temporarily locking hooks  6  for holding the aligning plate  3  at a temporarily locked position, which will be described below. 
   The temporarily locking hooks  6  are formed at positions to be locked to four corners of a plate part  30  of the aligning plate  3 , which will be described below. As shown in  FIGS. 3 and 4 , each of the temporarily locking hooks  6  includes an arm portion  60  which is extended from the inner wall  41  defining the engaging space  40  toward the terminal container  44 , and positioned outside both ends in a longitudinal direction L of the plate part  30 , a projection  63  which is projected from an end of the arm portion  60  remote from the inner wall  41  and adapted to be butted against a surface of the plate part  30  at a side facing the terminal container  44 , and a releasing plate portion  64  which connects a side face of the arm portion  60  to a side face of the projection  63 . When the male connector  2  is engaged, this releasing plate portion  64  is pressed with this male connector  2  thereby to flex the arm portion  60  outward of the engaging space  40 . In this manner, the plate part  30  is released from being held by the temporarily locking hook  6 , and allowed to move toward the terminal container  44 . 
   A plurality of the male terminals  5  as described above are obtained by stamping metal plates having electrical conductivity, each having a base end (not shown) which is attached to the terminal container  44 , and a rod-shaped electric connecting portion  5   a  which is adapted to be positioned in the engaging space  40 . This electric connecting portion  5   a  is engaged with a female terminal of the male connector  2 . 
   The aligning plate  3  is formed as a separate body from the connector housing  4 , for the purpose of positioning the electric connecting portions  5   a  at prescribed positions. Moreover, the aligning plate  3  is inserted into the engaging space  40  from an opening (entrance) of the engaging space  40  and so provided as to move in the inserting direction K in the engaging space  40 . As shown in  FIG. 2A , this aligning plate  3  has the plate part  30  in a plate-like shape, and a pair of permanently locking arms  32  which are respectively extended from both ends in the longitudinal direction L of the plate part  30 . 
   The plate part  30  has a plurality of terminal insertion holes  31  through which the electric connecting portions  5   a  are adapted to be inserted. Specifically, the aligning plate  3  sets positions of the electric connecting portions  5   a , by positioning the electric connecting portions  5   a  in the terminal insertion holes  31 . Moreover, the four corners of the plate part  30  are respectively supported by the temporarily locking hooks  6 , whereby the plate part  30  is held at a temporarily locked position, as shown by a solid line in  FIG. 1 . Further, the aligning plate  3  is inserted into the engaging space  40  in such a manner that a direction of thickness of the plate part  30  may be in parallel with the inserting direction K. 
   A pair of the permanently locking arms  32  are respectively provided in both end parts in the longitudinal direction L of the plate part  30  and at a center in a lateral direction of the plate part  30 . Moreover, these permanently locking arms  32  are erected from the surface of the plate part  30  at a side facing the terminal container  44 . When the aligning plate  3  is moved to the permanently locked position which is shown by a one-dot chain line in  FIG. 1 , the permanently locking arms  32  are locked to permanently locking locks  42  which are provided at a deeper side than the engaging space  40  in the connector housing  4 , thereby to fix the aligning plate  3  at the aforesaid permanently locked position. 
   The aligning plate  3  as described above is inserted into the engaging space  40  along the inserting direction K from the opening (entrance) of the engaging space  40 , and set at the aforesaid temporarily locked position, as shown in  FIG. 3A . In the state where the aligning plate  3  is positioned at the temporarily locked position, that is, prior to engagement of the male connector  2 , one end parts (or intermediate parts) of the electric connecting portions  5   a  remote from the base ends are positioned in the terminal insertion holes  31 . 
   Then, along with the engagement of the male connector  2 , the plate part  30  is released from being held by the temporarily locking hooks  6 , and pressed by the male connector  2  to the deeper side, that is, toward the terminal container  44  thereby to be moved to the permanently locked position. In the state where the plate part  30  is positioned at the permanently locked position, that is, in the state where the male connector  2  has been engaged with the connector  1  with the aligning plate, the other end parts of the electric connecting portions  5   a  close to the base ends are positioned in the terminal insertion holes  31 . 
   Then, a structure for holding the aligning plate  3  by the temporarily locking hooks  6  will be described in detail. 
   In the connector  1  according to the embodiment of the invention, a holding force of the aligning plate  3  by the temporarily locking hooks  6  is made high according to the following structure, for the purpose of enabling the aligning plate  3  to be reliably held at the temporarily locked position, even though a worker&#39;s hand or another connector different from the mating connector to be engaged is inadvertently inserted into the engaging space  40 , during transportation of the connector, for instance, in a state where the male terminals  5  and the aligning plate  3  are contained in the connector housing  4 . 
   Specifically, in the embodiment of this invention, the temporarily locking hooks  6  and the aligning plate  3  are designed in such a manner that when the plate part  30  of the aligning plate  3  which is held at the temporarily locked position is forcibly pressed toward the terminal container  44  with the worker&#39;s hand or the other connector different from the mating connector to be engaged, the arm portions  60  of the temporarily locking hooks  6  are flexed inward into the engaging space  40 , as shown in  FIGS. 3C and 3D , so that an escape of the plate part  30  toward the terminal container  44  may be prevented. 
   Moreover, shearing parts  34  are respectively provided in the four corners of the plate part  30 . When the plate part  30  of the aligning plate  3  which is held at the temporarily locked position is forcibly pressed with a large force exceeding a limit value of stress, by the worker&#39;s hand or the other connector different from the mating connector to be engaged, the shearing parts  34  are sheared, thereby to release the lock of the plate part  30  by the temporarily locking hooks  6 . These shearing parts  34  will be described below. 
   In order to flex the arm portions  60  inwardly, as described above, specifically, the plate part  30  of the aligning plate  3  is provided with dents  33  which are formed in a concave shape recessed from the surface of the plate part  30 , in the four corners of the surface of the plate part  30  at a side facing the terminal container  44 . Tip ends of the projections  63  of the temporarily locking hooks  6  are locked to these dents  33 . Each of the projections  63  is projected so as to approach a center of the engaging space  40  as it goes to the tip end, and at the same time, projected in a direction from the terminal container  44  to the opening of the engaging space  40 . 
   Further, the arm portion  60  of the temporarily locking hook  6  includes a first portion  61 , and a second portion  62  which is continued from the first portion  61  and extended in a direction toward the center of the engaging space  40 . As a whole, the arm portion  60  is so provided as to be curved in a direction toward the center of the engaging space  40 , as it goes from the opening of the engaging space  40  to the terminal container  44 . 
   When the plate part  30  in the state as shown in  FIG. 3B  is forcibly pressed toward the terminal container  44  with the worker&#39;s hand or the other connector different from the mating connector to be engaged, as shown in  FIGS. 3C and 3D , an inner face of the dent  33  is butted against the tip end of the projection  63 , whereby the tip end of the projection  63  is brought into line contact with the inner face of the dent  33 . A part of the tip end of the projection  63  to be brought into the line contact on this occasion is called as “a contact part” in this embodiment. Further, vectors generated in this contact part will be described referring to  FIG. 4 . 
   A point N in  FIG. 4  represents the contact part of the projection  63  with respect to the inner face of the dent  33 . A one-dot chain line M represents a tangent line of the contact part N. An arrow mark P 1  represents a load existing on the contact part N which is generated, when the plate part  30  is pressed, as a vector. A direction of this load P 1  is in parallel with the inserting direction K. An arrow mark P 2  represents a force of the inner face of the dent  33  pressing the contact part N perpendicularly to the tangent line M, as a vector. In short, the arrow mark P 2  is the vector generated in the contact part. 
   In order to flex the arm portion  60  inward into the engaging space  40 , it would be sufficient that the vector P 2  is directed to the center of the engaging space  40  rather than the direction of the load P 1 . Specifically, “the vector capable of pulling the arm portion  60  inward into the engaging space  40 ” is “the vector which is directed to the center of the engaging space  40  rather than the direction of the load P 1 , that is, the inserting direction K”. 
   In order to generate the vector P 2  which is directed as described above in the contact part N, an inclination angle of a taper face  63   a  (See  FIG. 4 ) of the projection  63  having the contact part N must be an acute angle with respect to the longitudinal direction L of the plate part  30  (that is, the direction of the surface of the plate part  30  which is not flexed). The “acute angle” is such an angle that the tangent line M of the contact part N is not parallel to the longitudinal direction L, even in case where the plate part  30  is pressed against the projection  63 , and where an angle between the arm portion  60  and the taper face  63   a  is enlarged. At this acute angle, the tangent line M becomes an inclined rectilinear line which is directed outward of the engaging space  40 , as it goes to the deeper side than the engaging space  40 . Moreover, an edge positioned at the tip end of this taper face  63   a  constitutes the aforesaid contact part N. 
   Additionally, in order to bring the surface of the plate part  30  at the side facing the terminal container  44  into contact with the contact part N which is provided on the taper face  63   a  having the acute inclination angle as described above, it is also necessary to make an inclination angle of the relevant surface acute. However, according to the embodiment of the invention, because the dent  33  is formed as described above, and the inner face of the dent  33  is brought into contact with the contact part N, it is possible to press the plate part  30  against the contact part N, without increasing a thickness of the plate part  30 . Moreover, by providing this dent  33 , it is possible to increase an overlapping amount between the projection  63  and the plate part  30 . 
   Further, according to the invention, it is not necessarily required to bring the contact part N into line contact with the surface of the plate part  30 , that is, the inner face of the dent  33 , but the contact part N may be brought into face contact. However, by bringing the contact part N into the line contact as described above, it becomes easy to make the vector P 2  directed so as to approach the center of the engaging space  40 . In short, it becomes easier to finely adjust the direction of the vector P 2 . 
   The shearing part  34  is shown by a dotted line in  FIGS. 2B and 4 . Specifically, the shearing part  34  is provided in a bottom part of the dent  33 , surrounding a protruded part  35  (See  FIG. 2B ) which is protruded from the bottom part. The “bottom part of the dent  33 ” means those areas which are formed having the smallest thickness, in the four corners of the plate part  30 . Moreover, the protruded part  35  is a part constituting the inner face of the dent  33 , and has a region to be brought into line contact with the contact part N. A shearing force of this shearing part  34  means the shearing force for a sectional plane “a” and a sectional plane “b” surrounding the protruded part  35 . Therefore, when the plate part  30  is pressed, the plate part  30  and the temporarily locking hook  6  are flexed, until the shearing part  34  is sheared. When the pressure exceeding this shearing force is applied to each of the four corners of the plate part  30 , the shearing part  34 , that is, the sectional planes “a” and “b” are sheared to detach the protruded part  35 , whereby the projection  63  loses the locked region with respect to the plate part  30 , and will be disengaged from the plate part  30 . 
   An upper limit value of the aforesaid load P 1  is equal to the shearing force of the aforesaid shearing part  34 . 
   In this embodiment of the invention, the aligning plate  3  is provided with the shearing parts  34  as described above, and hence, it is possible to prevent the temporarily locking hooks  6  from being broken, while the force for holding the plate part  30  by the temporarily locking hooks  6  is enhanced. Specifically, in case where a larger force exceeding the limit value of the stress is applied to the plate part  30 , the aligning plate  3  is sheared, that is, broken. Therefore, it is possible to re-use the connector housing  4  by exchanging the aligning plate  3  which has been broken. 
   The connector  1  with the aligning plate having the above described structure is transported, in a state where the male terminals  5  are contained in the connector housing  4  and the aligning plate  3  is positioned at the temporarily locked position. In case where the worker&#39;s hand or the other connector different from the mating connector to be engaged is inserted into the engaging space  40 , when this connector with the aligning plate is transported, for example, and the plate part  30  is forcibly pressed toward the terminal container  44 , the arm portion  60  is pulled inward into the engaging space  40  to be flexed inward. In this manner, the plate part  30  is prevented from moving toward the terminal container  44 , having the sufficient overlapping amount between the projection  63  and the plate part  30 , and the aligning plate  3  is reliably held at the temporarily locked position. 
   The above described embodiment represents only a typical form of the invention, but the invention is not limited to the embodiment. In other words, the invention can be put into practical use, while making various modifications within a scope not deviating from the spirit of the invention.
