The lever member 70 is molded from an insulating material such as synthetic resin. In order to make this lever member 70 make the 1st connector 11 and the 2nd connector 12 into a fully fitted state, or to make the 1st connector 11 and the 2nd connector 12 into a fitting release state, It is arranged between the housing 30 and the counterpart housing 60. In this example, the lever member 70 is interlocked with a fitting operation (hereinafter, referred to as "first lever operation") of an operator to the lever operating portion 71 (FIGS. 1 to 4, 8, and 9). Thus, the main body 33 of the housing 30 is inserted into the space inside the main body 65 of the counterpart housing 60. By the 1st lever operation, the fitting connector 1 will be in the fully fitted state of the 1st connector 11 and the 2nd connector 12, and will be a state which can close the main circuit and enable electricity supply. Moreover, the main body 33 of the housing 30 is connected to the lever member 70 of this example in conjunction with the extraction operation (henceforth "second lever operation") with respect to the lever operation part 71 by the worker. Is extracted from the space inside the main body 65 of the counterpart housing 60. As for the fitting connector 1, the 1st connector 11 and the 2nd connector 12 will be in a state of unfitting by the 2nd lever operation, and will open a main circuit and make it impossible to energize.

The lever member 70 of this example is rotatably attached to the main body 33 of the housing 30. Here, the lever member 70 is attached to two outer peripheral walls 33a and 33b of the main body 33 which face each other (FIGS. 1 to 3, 8 and 9). The lever member 70 has a first holding portion 72 disposed to face one outer circumferential wall 33a and a second holding portion 73 disposed facing the other outer circumferential wall 33b. To raise. The lever member 70 is attached to the main body 33 by being interposed between the first holding portion 72 and the second holding portion 73 from the outer circumferential walls 33a and 33b side. The 1st holding part 72 and the 2nd holding part 73 are plate-shaped parts extended from the lever operation part 71, respectively.

The main body 33 is provided with the rotating shaft part 35 arrange | positioned coaxially in each outer peripheral wall 33a, 33b (FIGS. 1-4, 8, and 9). Each rotating shaft portion 35 protrudes from the outer circumferential walls 33a, 33b in the axial direction in the opposite direction to each other. In the 1st holding part 72 and the 2nd holding part 73, the bearing part 74 which hold | maintains the rotating shaft part 35 freely about an axis is formed, respectively. The rotating shaft part 35 of this example is a thing mainly made a cylinder. On the other hand, the bearing part 74 of this example is of the shape which mainly makes the through-hole which the rotational shaft part 35 hold | maintains freely in the insertion state. The lever member 70 is held freely by the main shaft 33 of the housing 30 by the pivot shaft 35 and the bearing portion 74.

In addition, between the lever member 70 and the main body 65 of the counterpart housing 60, the main body 33 is interlocked with the relative rotation of the lever member 70 with respect to the main body 33 of the housing 30. ) And a guide mechanism for changing the relative position of the main body 65 is provided. The guide mechanism includes a guide portion 69 and a guide portion 75 for guiding the guide portion 69 in association with the relative rotation of the lever member 70 with respect to the main body 33 ( 1 and 3). The guide part 69 of this example is provided in the two outer peripheral walls 65a and 65b of the main body 65 which oppose each other (FIG. 12). Each of the guide portions 69 protrudes from the outer circumferential walls 65a and 65b in the opposite direction on the same axis. The guide part 75 is provided in the 1st holding part 72 and the 2nd holding part 73 of the lever member 70, respectively (FIG. 8). Each guide portion 75 cooperates with the relative rotation of the lever member 70 with respect to the main body 33, so that the first connector 11 and the second connector 12 between the disengaged state and the fully engaged state. It is set as the shape which enables relative movement between ()). Here, they are formed as arc-shaped through holes or arc-shaped grooves. Each guide part 75 is of the same shape which has arc-shaped walls (arc wall) facing each other, and is arrange | positioned so that the projection shape of each other may overlap in the axial direction of the rotational shaft part 35. In this guide mechanism, when fitting of the 1st connector 11 and the 2nd connector 12 started, each guide part 69 is inserted in each guide part 75, and the lever member after that is carried out. By the relative rotation of 70, the guide portion 69 is guided along the guide portion 75.

The guide portion 75 is closest between the shaft center of the rotation shaft portion 35 and the shaft center of the guide portion 69 when the first connector 11 and the second connector 12 are in a fully fitted state. Together with the second lever operation, the shape is determined so that the axis of the pivot shaft 35 and the axis of the guide portion 69 are separated. In addition, the guide portion 75 guides the guide portion 69 while sliding the guide portion 69 along one arced wall with the first lever operation, and the guide portion 69 is located between the guided portion 69 and the arced wall during the guide. The force acting between the main shaft 33 of the housing 30 and the main body 65 of the counterpart housing 60 approaches each other by the force acting between the rotating shaft portion 35 and the bearing portion 74. To exert a force, the shape of one arc wall is defined. In addition, the guide portion 75 guides the guide portion 75 while sliding the guide portion 69 along the other arc wall with the second lever operation, and at the time of the guide, between the guide portion 69 and the arc wall. The force exerted between the main body 33 of the housing 30 and the main body 65 of the counterpart housing 60 by the force acting on and the force acting between the rotating shaft part 35 and the bearing portion 74. To exert a force, the other arc wall is shaped.

Since the fitting connector 1 is provided with such a lever member 70, the fitting operation force at the time of fitting of the 1st connector 11 and the 2nd connector 12 can be reduced, and also the 1st connector ( 11) and the extraction operation force at the time of extracting of the 2nd connector 12 can be reduced.

Here, in this fitting connector 1, a plate-like thing is used for the 1st terminal 21 and the 2nd terminal 22. As shown in FIG. For this reason, the lever member 70 orthogonally crosses the axial direction of the rotation shaft (rotation shaft part 35 or bearing part 74) with respect to the plane of the first terminal 21 or the plane of the second terminal 22. It is preferable to make it. Thereby, in this fitting connector 1, even when the 1st terminal 21 and the 2nd terminal 22 are hardness, when performing the 1st lever operation or the 2nd lever operation, the hardness direction It becomes a direction along the plane of this 1st terminal 21 or the plane of the 2nd terminal 22. FIG. For this reason, in this fitting connector 1, when the 1st terminal 21 and the 2nd terminal 22 are hardened, between the 1st terminal 21 and the 1st counterpart terminal 41, the 1st terminal ( Between the 21 and the third counterpart terminal 43, between the second terminal 22 and the second counterpart terminal 42, and between the second terminal 22 and the fourth counterpart terminal 44, the contact point is a first terminal. Since it moves along the plane of 21 and the plane of the 2nd terminal 22, the increase in the load in the contact can be suppressed, and it can suppress the biting in between them. Therefore, this fitting connector 1 can suppress the increase of a fitting operation force and an extraction operation force, or can improve the workability of a fitting operation and an extraction operation.

Moreover, the rotation shaft of the lever member 70 is between the input side electrical connection part 21a of the 1st terminal 21, and the output side electrical connection part 21b (the input side electrical connection part 22a of the 2nd terminal 22, and the output side). In the electrical connection part 22b), in the orthogonal plane with respect to the plane of the 1st terminal 21 (plane of the 2nd terminal 22), the 1st and 3rd counterpart terminals 41 and 43 ( It is preferable to arrange | position on the virtual plane along the insertion direction of the 1st terminal 21 (2nd terminal 22) with respect to the 2nd and 4th counterpart terminals 42 and 44. Thereby, In this fitting connector 1, even when the 1st terminal 21 and the 2nd terminal 22 are hard when the 1st lever operation and the 2nd lever operation are performed, the 1st terminal 21 and the 1st terminal Between the counterpart terminal 41, between the first terminal 21 and the third counterpart terminal 43, between the second terminal 22 and the second counterpart terminal 42, the second terminal 22 and the fourth counterpart terminal. Among 44, that Since the difference in the relative amount of movement according to the hardness can be reduced, it is possible to further suppress the entanglement between them, etc. Therefore, the fitting connector 1 has a high suppression effect of an increase in the fitting operation force and the extraction operation force, and The workability of the fitting work and the extraction work can be further improved.

In the fitting connector 1 of the present embodiment described above, the main circuit is closed by energizing the fitting state of the first connector 11 and the second connector 12 in a fully fitted state. Make it possible. On the other hand, the fitting connector 1 opens the main circuit by bringing the first connector 11 and the second connector 12 into the released state when the vehicle is not in the inspection work or the salvation work. And cut off, making it impossible to conduct electricity between the current input section 51c and the current output section 52c.

Here, between the current input part 51c and the current output part 52c in a fully fitted state (for example, the male screw member B2 of the current input part 51c and the male screw member B2 of the current output part 52c). Between the first conductive member 51, the first counterpart terminal 41, the first terminal 21, the third counterpart terminal 43, and the second conductive member 52. Current flows through the energization path Ep1, the first conductive member 51, the second counterpart terminal 42, the second terminal 22, the fourth counterpart terminal 44, and the second conductive member 52. The second energization path Ep2 is provided in parallel (FIG. 7). By this parallel circuit, in the fitting connector 1 of this embodiment, the electric current which flowed into the electric current input part 51c is classified into the 1st electricity supply path Ep1 and the 2nd electricity supply path Ep2, and 1st electricity supply is carried out. The currents of the path Ep1 and the second conduction path Ep2 may be joined at the current output unit 52c.

Since the fitting connector 1 of this embodiment has such a parallel circuit, for example, when the magnitude | size of the electric current which flows through a main circuit is the same as that of a conventional series circuit, compared with the series circuit, the 1st The current flowing through the energization path Ep1 and the second energization path Ep2 becomes small. For this reason, the fitting connector 1 in this case is compared with components, such as a terminal which comprises the series circuit, and the component which comprises the 1st electricity supply path Ep1 (the 1st conductive member 51 and the 1st counterpart terminal ( 41, the first terminal 21, the third counterpart terminal 43, the second conductive member 52, and the parts (first conductive member 51 and second) constituting the second conduction path Ep2. The allowable current of the component can be reduced while maintaining the durability of the counterpart terminal 42, the second terminal 22, the fourth counterpart terminal 44, and the second conductive member 52. Since the fitting connector 1 in this case can use a component having a small allowable current in the first conducting path Ep1 and the second conducting path Ep2, the parts can be made thinner and smaller in size. can do. For example, since the fitting connector 1 can be reduced in weight due to its thinness and size, the fitting connector 1 is also improved in durability against external input (for example, road input and acceleration / deceleration when driving a vehicle). You can. The fitting connector 1 is a component constituting the first conduction path Ep1 or a component constituting the second conduction path Ep2. If there is an existing component corresponding to a small allowable current, the fitting connector 1 is used. By doing so, the development man-hour can be reduced, and the cost can be reduced.

On the other hand, in the case of the conventional series circuit, when the magnitude of the current flowing through the main circuit is increased, if the current exceeds the allowable current of the component of the series circuit, the plate thickness of the component needs to be thickened or the body size is increased. There is. However, in the fitting connector 1 of this embodiment, since the current input part 51c and the current output part 52c become a parallel circuit by the 1st electricity supply path Ep1 and the 2nd electricity supply path Ep2, For example, when the increased current is less than twice, since the current flowing in the first conducting path Ep1 and the second conducting path Ep2 is smaller than the current flowing in the series circuit, the first conducting path Ep1 is changed. The allowable current of the component can be made small while maintaining the durability of the component forming the component and the component forming the second conduction path Ep2. Therefore, the fitting connector 1 at this time can be reduced in weight due to the thinning and miniaturization of the parts thereof, and the durability against external input can be improved.

Moreover, in the fitting connector 1 of this embodiment, since the electric current which flows in the 1st electricity supply path Ep1 and the 2nd electricity supply path Ep2 is smaller than the electric current which flows through a series circuit, when the enlarged electric current is less than 2 times, By using some or all of the components of the conventional series circuit, the first conduction path Ep1 and the second conduction path Ep2 can be formed without deteriorating the durability.

In the fitting connector 1 of the present embodiment, even if the increased current exceeds twice, the current flowing through the first conducting path Ep1 and the second conducting path Ep2 is smaller than the current flowing through the series circuit. Therefore, while maintaining the durability of the components constituting the first conduction path Ep1 and the components constituting the second conduction path Ep2, the allowable current of the components can be minimized. Therefore, the fitting connector 1 at this time can minimize the thickening and the enlargement of the part to a minimum, and can improve also the durability with respect to an external input.

Thus, the fitting connector 1 of this embodiment can easily ensure durability, even if the magnitude | size of the electric current which flows through a main circuit changes with respect to the application vehicle of a phenomenon, for example.

By the way, in this fitting connector 1, in order to aim at the stability of the electric current on a parallel circuit, and the uniformity of the durability of each component in the 1st electricity supply path Ep1 and the 2nd electricity supply path Ep2, By setting the resistance value of the current carrying path Ep1 and the resistance value of the second current carrying path Ep2 to be the same value, the current flowing through the current input unit 51c is converted into the first current carrying path Ep1 and the second current carrying path Ep2. It is preferable to divide into two. For this reason, in this fitting connector 1, the 1st and 2nd terminals 21 and 22 are made so that the resistance value of the 1st electricity supply path Ep1 and the resistance value of the 2nd electricity supply path Ep2 may become the same value. And first to fourth counterpart terminals 41-44 and first and second conductive members 51 and 52.

For example, in this embodiment, the 1st terminal 21 and the 2nd terminal 22 are shape | molded in the same shape, and the 1st-4th counterpart terminal 41-44 is shape | molded in the same shape, respectively. In addition, the first conductive member 51 and the second conductive member 52 are molded in the same shape. Therefore, in this fitting connector 1, the 1st and 2nd terminals 21 and 22 and 1st are made so that the path length of the 1st electricity supply path Ep1 and the path length of the 2nd electricity supply path Ep2 may become the same. The first to fourth counterpart terminals 41-44 and the first and second conductive members 51 and 52 are disposed so that the resistance value of the first conduction path Ep1 and the resistance value of the second conduction path Ep2 It is supposed to be the same value. Here, as shown above, the arrangement place of the first and second counterpart terminals 41 and 42 with respect to the first conductive member 51 and the third and fourth counterpart terminals 43 with respect to the second conductive member 52 are described. And 44 are arranged, and the first conductive member 51 and the second conductive member 52 are disposed so that the current input unit 51c and the current output unit 52c are arranged on opposite sides. For this reason, in the fitting connector 1 of this embodiment, the path length of the 1st electricity supply path Ep1 and the path length of the 2nd electricity supply path Ep2 become the same length.

13 and 14, the fitting connector 1 has a current in the counterpart housing 60, centered on the first to fourth counterpart terminals 41-44 in a lattice arrangement. The first conductive member 51 and the second conductive member 52 may be held so that the input unit 51c and the current output unit 52c are disposed on the same side. In this case, for example, in the second conductive member 52, the arrangement positions of the first and second counterpart terminals 41, 42 with respect to the first conductive member 51 are left in the same manner as in the above example. The placement positions of the third and fourth counterpart terminals 43 and 44 (that is, positions of the first output side electrical contact 52a and the second output side electrical contact 52b), respectively, or the second conductive member 52. Arrangement of the first and second counterpart terminals 41, 42 with respect to the first conductive member 51, with the arrangement place of the third and fourth counterpart terminals 43, 44 with respect to What is necessary is just to change a place (namely, the position of the 1st input side electrical connection part 51a and the 2nd input side electrical connection part 51b). Here, the former is illustrated. Even in this arrangement, the fitting connector 1 can obtain the same effects as in the above example.

Here, also in the fitting connector 1 of FIG. 13 and FIG. 14, it is preferable to set so that each resistance value may be the same value for the 1st electricity supply path Ep1 and the 2nd electricity supply path Ep2. For example, in the example of this figure, the path length of the 2nd electricity supply path Ep2 is long with respect to the path length of the 1st electricity supply path Ep1, and the resistance value of the 1st electricity supply path Ep1 is 2nd electricity supply. It is smaller than the resistance value of the path Ep2. For this reason, in this case, for example, the plate | board thickness of the 1st terminal 21 is made thick (adapting the shape of the 1st and 3rd counterpart terminals 41 and 43 to the 1st terminal 21, for example). By increasing the cross-sectional area perpendicular to the direction, the resistance value of the first conduction path Ep1 is increased or the plate thickness of the second terminal 22 is made thin (the shapes of the second and fourth counterpart terminals 42, 44). It is good to make the resistance value of the 2nd electricity supply path | pass Ep2 small by making the orthogonal cross-sectional area with respect to the electricity supply direction small. Thereby, also in the fitting connector 1 of FIG. 13 and FIG. 14, stability of the electric current on a parallel circuit can be aimed at.
