Description

OMNIBUS BAR RECEPTION STRUCTURE AND HIGH-VOLTAGE CONNECTION DEVICE

The present invention relates to a bus bar receiving structure which includes a conductive bus bar having a ribbon plate shape and an insulating housing for accommodating a bus bar. The present invention also relates to a high-voltage connection device having the bus bar receiving structure.

CONTEXT

A related art high voltage connection device (power distribution member) includes a first bus bar, a second bus bar and a third bus bar for power distribution, and a housing (a housing member). in the related art) in which the first bus bar, the second bus bar and the third bus bar are isolated and held. Each bus bar has terminal portions exposed outside the housing at two ends, and a portion of the bus bar between the terminal portions is held in the housing. The housing is a resin cast product, and is provided with three grooves designed to hold the bus bars when the bus bars are inserted into the grooves. The three grooves are formed in linear shapes in accordance with the shapes of the bus bars. A retaining protrusion for preventing each bus bar from coming off is formed in an opening of each of the three grooves. A rib for keeping each bus bar in a press-fitted condition is formed on an inner side wall of each of the three grooves in a manner projecting slightly from the inner side wall (see, for example, JP2016-63653A).

In the related art, the three grooves in the housing are formed into shapes that hold the bus bars. Therefore, each of the grooves is formed into a shape having as little additional space as possible (formed into a shape in which a playing space is not provided unnecessarily). When each of the bus bars is simply formed in a short linear shape, a dimensional variation between the bus bars is not that large. However, when each of the bus bars is long, a dimensional variation needs to be taken into consideration and it is necessary to set a dimensional tolerance for it to be large. As often seen in recent years, an arrangement and a path relating to an electrical connection is complicated, and thus the bus bars often have a plurality of curved parts. Therefore, when the amount of dimensional errors for parts of the bus bar between each of the bent parts accumulates in an increasing manner (towards an upper limit), the length of the bus bar may become too long beyond of a predetermined dimensional tolerance with which the bus bar is supposed to be manufactured. For example, when the bus bars are long enough to exceed the dimensional tolerance, such excess bus bar length cannot be absorbed in a related art bus bar receiving structure with the three grooves. As a result, when the bus bars are forcibly inserted into the three grooves, the housing may for example be damaged.

Illustrative aspects of the present invention relate to a bus bar receiving structure in which even when dimensional errors of respective parts of a bus bar increasingly accumulate to exceed an overall dimensional tolerance of the bus bar and As the bus bar is put into a housing without noticing the excess, the excess can be absorbed in the housing and a high-voltage connection device having the bus bar receiving structure.

In accordance with an illustrative aspect of the present invention, a bus bar receiving structure includes a bus bar which is electrically conductive and which has a ribbon plate shape and an electrically insulating housing and adapted to accommodate the bus bar. bus bar. The bus bar includes a main path portion, a plurality of terminal portions adapted to be exposed outside the housing when the bus bar is received in the housing, and an intermediate portion located between at least one of the plurality of terminal portions and the main path part and continues with the main path part in a curved or linear fashion. The housing includes a first receiving portion designed to accommodate the main path portion and a second receiving portion designed to accommodate the intermediate portion and is formed such that a first width of the first receiving portion is greater. larger than a second width of the second reception part.

Other aspects and advantages of the invention will be apparent from the following description, the drawings and this disclosure as a whole.

The intermediate receiving part 36 is formed to have the width W3 corresponding to the thicknesses of the first bus bar 5 and of the second bus bar 6 (the intermediate parts 12 and 24). The intermediate receiving portion 36 is not only formed as a receiving portion but also formed as a holding portion 47 which holds the intermediate portions 12 and 24 (A holding structure is not particularly limited. For example, a rib may be provided and the intermediate portions 12 and 24 may be held by press fit. In addition, since the housing cover 8 is provided, it is not necessary to form a retaining protrusion as. in related art). On the other hand, the intermediate receiving part 37 is formed to have the width W3 only at the first bus bar side 5 (intermediate part 13) (Similarly, for example, the intermediate receiving part 37 can be formed to have the width W3 at the side of the second bus bar 6 (an intermediate part 25) only). The main path part 9 is not curved as described above since the intermediate receiving parts 36 and 37 have the width W3. The intermediate receiving part 37 is also formed as a holding part 47.

While the present invention has been described with reference to certain illustrative embodiments thereof, the scope of the present invention is not limited to the illustrative embodiments described above, and those skilled in the art will understand that various changes and modifications may be made thereto without departing from the scope of the present invention as defined.

According to one aspect of the embodiments described above, a bus bar receiving structure includes a bus bar which is electrically conductive and which has a ribbon plate shape and an electrically insulating casing and designed. to accommodate the bus bar. The bus bar includes a main path portion, a plurality of terminal portions adapted to be exposed from the housing when the bus bar is received in the housing, and an intermediate portion located between at least one of the plurality of terminal portions and the main path part and continues with the main path part in a curved or straight manner. The housing includes a first receiving portion designed to accommodate the main path portion and a second receiving portion designed to accommodate the intermediate portion and is formed such that a first width of the first receiving portion is greater. larger than a second width of the second reception part.

According to the bus bar receiving structure having the configuration described above, since the housing is formed such that the width of the part which accommodates the main path part of the bus bar is larger than the width of the part which accommodates the intermediate part of the bus bar, even when dimensional tolerances of respective parts of the bus bar accumulate in an increasing manner, the length of the bus bar exceeds an overall dimensional tolerance with which the bar bus is supposed to be manufactured and the bus bar is housed in the housing without noticing the excess, the excess can be absorbed in the housing by bending the main path portion of the bus bar as the housing is provided with a part having a great width. As a result, the housing can be prevented from being damaged, for example.

The first receiving portion may include at least a narrow portion located along a direction in which the main path portion extends when the bus bar is received in the housing, the narrow portion having a third width smaller than the first width. The narrow portion may be formed with a rib protruding from the first receiving portion in a direction perpendicular to the direction in which the main path portion extends. The rib may have a constriction at one end side in a direction opposite to a direction in which the bus bar is inserted into the housing.

With this configuration, since the housing is formed with the narrow part at the location of the part which accommodates the main path part of the bus bar, the positions of a bending position of the bus bar can be controlled. and (unnecessary) displacement / scraping of the main path portion in the housing can be avoided, instead of simply accommodating the bus bar which has a long shape.

The second receiving part can be a holding part designed to hold the middle part.

With this configuration, since the housing is formed such that the part which accommodates the intermediate part of the bus bar is also formed as a holding part which holds the intermediate part, the bus bar can be held, and thus a Home state of the bus bar in the housing can be stabilized.

The third width of the narrow part may be larger than the second width of the holding part.

With this configuration, since the narrow part is formed to have a larger width than the holding part, the narrow part can be specialized as a part for controlling the bending position of the bus bar and a part preventing the bending of the bus bar. displacement / scraping of the main road part; That is, the narrow part can keep a bending degree of freedom of the bus bar and can prevent displacement / scraping of the main path part.

The bus bar may include a first bus bar and a second bus bar and the main path portions of each of the first bus bar and the second bus bar are arranged substantially parallel to each other when the first bus bar and the second bus bar are. accommodated in the housing. The housing may include a housing body configured to accommodate the first bus bar and the second bus bar and a housing cover adapted to attach to and cover the housing body. The housing body may be formed with a partition wall designed to, when the first bus bar and the second bus bar are received in the housing body, be positioned between the main path portions of each of the first bus bar and the second bus bar. the second bus bar such that the partition wall separates the first bus bar and the second bus bar. The housing cover may be formed with a partition wall contact portion designed to, when the housing cover is attached to the housing body, contact an end portion of the partition wall. The narrow part may be formed with a rib protruding from the partition wall of the first receiving part in the direction perpendicular to the direction in which the main path part extends. The housing cover may be formed with ribs extending along the partition wall contact portion on both sides of the partition wall contact portion.

With this configuration, since the bus bar includes the first bus bar and the second bus bar and the housing includes the housing body and the housing cover, a better shape of the bus bar receiving structure can be made. provided.
