     SUMMARY OF THE INVENTION 
     Problems to be Solved 
     In a structure for connecting the respective device-side terminals and the respective wire-side terminals using the connector described in Patent Document 1, the lengths of the respective device-side terminals and those of the respective wire-side terminals need to be changed to correspond to a connection mode in the case of changing the connection mode such as connection angles of the respective wire-side terminals to the respective device-side terminals for the convenience of layout. Further, the shape of a seal member or the like for sealing between the housing and the service cover also needs to be changed in addition to the shape of the housing including the service cover. 
     The present disclosure aims to provide a connector capable of simplifying the configuration thereof and enhancing the versatility of terminals to be connected. 
     Means to Solve the Problem 
     A first aspect of the present disclosure is directed to a connector with a plurality of busbars provided in parallel to each other; and a plurality of housings made of resin for individually covering around each busbar, wherein one end of each busbar includes a first connecting portion to be connected to a first terminal, the other end of each busbar includes a second connecting portion to be connected to a second terminal, the housing is molded using the busbar as an insert and held in close contact with a peripheral surface of the busbar, the first and second connecting portions are exposed outside the housing covering around the busbar including the first and second connecting portions, the respective first connecting portions are located on a straight line along an arrangement direction of the one ends of the busbars, and the respective second connecting portions are located on a straight line along an arrangement direction of the other ends of the busbars. 
     According to the first aspect, the respective first terminals are connected to the respective first connecting portions outside the respective housings. Further, the respective second terminals are connected to the respective second connecting portions outside the respective housings. Here, the respective first connecting portions are located on the straight line along the arrangement direction of the one ends of the busbars. Further, the respective second connecting portions are located on the straight line along the arrangement direction of the other ends of the busbars. Thus, in the case of changing a connection mode such as connection angles of the second terminals to the first terminals, the shapes of the first terminals and the second terminals to be connected to the connector need not be changed by preparing the connector including the plurality of busbars and the plurality of housings shaped to correspond to the connection mode. 
     According to the first aspect, the respective housings are molded using the respective busbars as inserts and held in close contact with the peripheral surfaces of the respective busbars. Thus, sealing is provided between the respective housings and the respective busbars by the respective housings themselves. In this way, a sealing member for sealing between the respective housings and the respective busbars is unnecessary. 
     According to the first aspect, since the busbars, i.e. the housings, are independent of each other, relative positions of the busbars can be finely adjusted when the connector is connected. Thus, variations of relative positions of the respective first terminals, relative positions of the respective second terminals and relative positions of the first and second terminals can be absorbed by finely adjusting the relative positions of the respective busbars. 
     A second aspect of the present disclosure is directed to a connector with a plurality of busbars provided in parallel to each other, and one housing made of resin for collectively covering around the plurality of busbars, wherein one end of each busbar includes a first connecting portion to be connected to a first terminal, the other end of each busbar includes a second connecting portion to be connected to a second terminal, the housing is molded using the busbars as inserts and held in close contact with peripheral surfaces of the respective busbars, the respective first connecting portions and the respective second connecting portions are exposed outside the housing, the respective first connecting portions are located on a straight line along an arrangement direction of the one ends of the busbars, and the respective second connecting portions are located on a straight line along an arrangement direction of the other ends of the busbars. 
     According to the second aspect, the respective first terminals are connected to the respective first connecting portions outside the housing. Further, the respective second terminals are connected to the respective second connecting portions outside the housing. Here, the respective first connecting portions are located on the straight line along the arrangement direction of the one ends of the busbars. Further, the respective second connecting portions are located on the straight line along the arrangement direction of the other ends of the busbars. Thus, in the case of changing a connection mode such as connection angles of the second terminals to the first terminals, the shapes of the plurality of first terminals and the plurality of second terminals to be connected to the connector need not be changed by preparing the connector including the plurality of busbars and the housing shaped to correspond to the connection mode. 
     According to the second aspect, the housing is molded using the respective busbars as inserts and held in close contact with the peripheral surfaces of the respective busbars. Thus, sealing is provided between the housing and the respective busbars by the housing itself. In this way, a sealing member for sealing between the housing and the respective busbars is unnecessary. 
     According to the second aspect, since the connector is configured by integrating the plurality of busbars by one housing, the number of components of the connector can be reduced. 
     Effect of the Invention 
     According to the connector of the present disclosure, a configuration can be simplified and the versatility of terminals to be connected can be enhanced.

     Functions of this embodiment are described. 
     The respective device-side terminals  210  are connected to the respective first connecting portions  20   a,    40   a  outside the respective housings  30 ,  50 . Further, the respective wire-side terminals  83  are connected to the respective second connecting portions  20   b,    40   b  outside the respective housings  30 ,  50 . Here, the respective first connecting portions  20   a,    40   a  are located on the straight line A 1  along the extending direction Y. Further, the respective second connecting portions  20   b,    40   b  are located on the straight line A 2  along the orthogonal direction Z. Thus, in the case of changing a connection mode such as connection angles of the wire-side terminals  83  to the device-side terminals  210 , the shapes of the device-side terminals  210  and the wire-side terminals  83  to be connected to the connector  10  need not be changed by preparing the connector  10  including the respective busbars  20 ,  40  and the respective housings  30 ,  50  shaped to correspond to the connection mode (function 1). 
     Further, according to the configuration of this embodiment, the respective housings  30 ,  50  are molded using the respective busbars  20 ,  40  as inserts and held in close contact with the peripheral surfaces of the respective busbars  20 ,  40 . Thus, sealing is provided between the respective housings  30 ,  50  and the respective busbars  20 ,  40  by the respective housings  30 ,  50  themselves. In this way, a seal member for sealing between the respective housings  30 ,  50  and the respective busbars  20 ,  40  is unnecessary (function 2). 
     Effects of this embodiment are described. 
     (1) The connector  10  includes the first and second busbars  20 ,  40  provided in parallel to each other, and the first and second housings  30 ,  50  made of resin for individually covering the respective busbars  20 ,  40 . One end of each busbar  20 ,  40  includes the first connecting portion  20   a,    20   b  to be connected to each device-side terminal  210 , and the other end of each busbar  20 ,  40  includes the second connecting portion  20   b,    40   b  to be connected to each wire-side terminal  83 . The respective housings  30 ,  50  are molded using the respective busbars  20 ,  40  as inserts and held in close contact with the peripheral surfaces of the respective busbars  20 ,  40 . The respective first connecting portions  20   a,    20   b  and the respective second connecting portions  20   b,    40   b  are exposed outside the respective housings  30 ,  50 . The respective first connecting portions  20   a,    40   a  are located on the straight line A 1  along the extending direction Y, and the respective second connecting portions  20   b,    40   b  are located on the straight line A 2  along the orthogonal direction Z. 
     According to this configuration, since the functions 1 and 2 are achieved, the configuration of the connector  10  can be simplified and the versatility of the terminals to be connected can be enhanced. 
     Further, according to the above configuration, since the respective busbars  20 ,  40 , i.e. the respective housings  30 ,  50  are independent of each other, relative positions of the respective busbars  20 ,  40  can be finely adjusted when the connector  10  is connected. Thus, variations of relative positions of the respective device-side terminals  210 , relative positions of the respective wire-side terminals  83  and relative positions of the device-side terminals  210  and the wire-side terminals  83  can be absorbed by finely adjusting the relative positions of the respective busbars  20 ,  40 . 
     (2) The connector  10  includes the shield member  120  to which the respective housings  30 ,  50  are fixed and which electromagnetically shields the respective busbars  20 ,  40 . 
     According to this configuration, a state where the respective first connecting portions  20   a,    40   a  are located on the straight line A 1  and the respective second connecting portions  20   b,    40   b  are located on the straight line A 2  can be held by the shield member  120 . Further, the respective busbars  20 ,  40  are electromagnetically shielded by the shield member  120 . In this way, the number of components of the connector  10  can be reduced as compared to a configuration in which a fixing member for fixing the respective housings  30 ,  50  and the shield member  120  are separately provided. 
     This embodiment can be modified and carried out as follows. The above embodiment and the following modifications can be carried out in combination without technically contradicting each other. Note that, in the following modification shown in  FIG. 10 , components corresponding to those of the above embodiment are denoted by reference signs “3**” obtained by adding “300” to the reference signs “**” of the above embodiment and repeated description is omitted. 
     As shown in  FIG. 10 , it is also possible to adopt a connector  310  including a first busbar  320  and a second busbar  340  and one housing  300  made of resin for collectively covering around the busbars  320 ,  340 . In this configuration, the housing  300  is molded using the respective busbars  320 ,  340  as inserts and held in close contact with the peripheral surfaces of the respective busbars  320 ,  340 . First connecting portions  320   a,    340   a  and second connecting portions  320   b,    340   b  are respectively exposed outside the housing  300 . The respective first connecting portions  320   a,    340   a  are located on a straight line A 1  and the respective second connecting portions  320   b,    340   b  are located on a straight line A 2 . 
     According to this configuration, since the functions 1 and 2 are achieved, the configuration of the connector  310  can be simplified and the versatility of the terminals to be connected can be enhanced. 
     Further, since the connector  310  is configured by integrating the respective busbars  320 ,  340  by one housing  300  according to the above configuration, the number of components of the connector  310  can be reduced. 
     It is also possible to adopt a first busbar and a second busbar arranged such that center axes of first insertion holes  22 ,  42  coincide. In this configuration, the center axes of the first insertion holes  22 ,  42  coincide with an arrangement direction of one ends of the first and second busbars. In this case, the first and second busbars and the both device-side terminals  210  may be collectively connected by one bolt. Similarly, it is also possible to adopt a first busbar and a second busbar arranged such that center axes of second insertion holes  26 ,  46  coincide. In this configuration, the center axes of the second insertion holes  26 ,  46  coincide with an arrangement direction of the other ends of the first and second busbars. In this case, the first and second busbar and the both wire-side terminals  83  may be collectively connected by one bolt. 
     In the embodiment, the front edge parts of the device-side extending portions  21 ,  41  are located on the straight line A 1 . However, at least the first connecting portions  20   a,    40   a  may be located on the straight line A 1 . In this case, the front edge parts of the device-side extending portions  21 ,  41  may not be located side by side along the straight line A 1 . Similarly, in the embodiment, the edge parts on the base end sides in the extending direction Y of the wire-side extending portions  25 ,  45  are located on the straight line A 2 . However, at least the second connecting portions  20   b,    40   b  may be located on the straight line A 2 . In this case, the edge parts on the base end sides in the extending direction Y of the wire-side extending portions  25 ,  45  may not be located side by side along the straight line A 2 . 
     Each busbar  20 ,  40  may be an I-shaped busbar having the inclined portion omitted therefrom and including a device-side extending portion and a wire-side extending portion arranged along the same direction or may be an L-shaped busbar having the inclined portion omitted therefrom and including a device-side extending portion and a wire-side extending portion located on the same plane and orthogonal to each other. 
     The connector  10  may include three or more busbars and three or more housings made of resin for individually covering around these busbars. Further, the connector  310  in the aforementioned modification may include three or more busbars and a housing made of resin for collectively covering around these busbars. 
     Although an example of the connector  100  having the facing direction X, the extending direction Y and the orthogonal direction Z orthogonal to each other has been described in the embodiment, “orthogonal” means not only strictly orthogonal, but also substantially orthogonal within a range in which functions and effects in the embodiment are achieved. Further, “parallel” means not only strictly parallel, but also substantially parallel within a range in which functions and effects in the embodiment are achieved. 
     A curved or bent part between the inclined portion  24 ,  44  and the wire-side extending portion  25 ,  40  of the busbar  20 ,  40  of the embodiment is an example of an intermediate bent portion of the busbar. 
     The present disclosure includes the following implementation examples. Reference signs of several constituent elements of illustrative embodiments are given not for limitation, but for understanding assistance. Matters described in the following implementation examples may be partly omitted or several of the matters described in the implementation examples may be selected or extracted and combined.
