  In addition, the movement (rotation) of the bus bar around the axis of the bolt is not particularly restricted, and this is caused by the friction generated between the nut and the bus bar receiving the fastening torque in the fastening process of the bolt and the nut. The bus bar may rotate carelessly. As a result, in the above fastening process, the posture of the bus bar is not stable, and the bolt and nut must be fastened while avoiding the rotation of the bus bar, so that the connection work between the external connection terminal and the bus bar is complicated. There is a risk of becoming. In addition, even after fastening, the bus bar repeatedly receives unintentional external force and repeatedly rotates, so that the bolts and nuts gradually loosen, resulting in poor connection between the external connection terminals and the bus bar, There is also a risk that the posture may shift.

  In view of such circumstances, the present invention aims at sufficient protection of a connection portion between a connector terminal provided on an electrical connector for a power supply and a conductive strip terminal attached to one end of the conductive strip, and a connector terminal. An object of the present invention is to provide a protective cover and an assembly of an electrical connector with a conductive strip and a protective cover, which can facilitate the connection work between the conductive strip body terminal and the conductive strip terminal.

  According to the present invention, the above-mentioned problems are solved by the following first invention with respect to the protective cover, and by the second invention with respect to the assembly of the electrical connector with a conductive strip and the protective cover.

<First invention>
A protective cover according to a first aspect of the present invention is a protective cover that covers a connection portion between a connector terminal provided in an electrical connector for power supply and a conductive strip terminal provided at one end of the conductive strip, A plate-like connector-side connection part that forms a part and protrudes from the housing of the electrical connector and a plate-like conductive stripe-side connection part that forms a part of the conductive stripe terminal overlap in the thickness direction of both connection parts. The connecting portions formed by being joined together and fastened with bolts and nuts from both sides in the plate thickness direction are covered.

  In such a protective cover, in the first invention, the protective cover includes a first cover member that supports the connector-side connecting portion, and a second cover member that is attached to the first cover member. One cover member stands from the base wall facing the plate surface of the connector side connecting portion and both ends of the base wall in the cover width direction perpendicular to both the plate thickness direction and the conductive strip longitudinal direction. The base wall of the first cover member has a housing portion for housing and supporting a bolt head or a nut from the inner wall surface of the base wall to the thickness of the connector-side connecting portion. The pair of side walls are formed with a side connector restricting surface on the opposing inner wall surface that restricts movement of the connector side connecting portion in the cover width direction. Conductive strip terminal and conductive strip Lateral guide Denjo body regulating surface for regulating the movement of at least one of the cover width direction is characterized in that it is formed on the opposing inner wall surface.

  In the first invention, the connection portion formed by fastening the conductive strip side connection portion of the conductive strip terminal with the bolt and the nut to the connector side connection portion of the connector terminal supported by the first cover member is the first portion. By attaching the second cover member to the cover member, the cover member is accommodated in the protective cover. Therefore, the entire connecting portion is covered and protected by the protective cover.

  Further, the movement in the cover width direction of the connector side connecting portion is regulated by the side connector regulating surface of the first cover member, and the movement in the cover width direction of at least one of the conductive strip terminal and the conductive strip is performed. It is regulated by the side conductive strip regulating surface of the first cover member. Therefore, in the fastening process of the bolt and nut, the rotation of the conductive strip terminal and the conductive strip around the bolt axis due to the fastening torque is restricted, so that the connection work between the connector terminal and the conductive strip terminal is easy. It becomes.

  Further, since the head portion or nut of the bolt can be accommodated and supported by the accommodating portion of the first cover member, the bolt or nut can be supported by the first cover member in the fastening process of the bolt and nut. This makes it easier to connect the connector terminal and the conductive strip terminal.

  In the first invention, the protective cover is connected to the connector side connecting portion formed by bending the connector terminal outside the housing in the thickness direction perpendicular to the insertion / extraction direction of the electrical connector. You may come to cover the connection part with the conductive strip side connection part.

  In the first invention, the pair of side walls of the first cover member has a support groove portion for supporting the cover width direction end portion of the connector side connection portion extending from the inner wall surface of the side wall and extending in the longitudinal direction of the conductive strip. It is good also as a surface perpendicular | vertical to a cover width direction being formed as a side connector control surface among the inner wall surfaces which form the said support groove part.

  When the cover width direction end portion (side end portion) of the connector side connection portion of the connector terminal is accommodated in the support groove portion of the first cover member, the inner wall surface forming the support groove portion is perpendicular to the cover width direction. The side end portion of the connector side connection portion is positioned so as to be able to abut against a flat surface, that is, the side connector restriction surface, and movement of the connector side connection portion in the cover width direction is restricted. In addition, a plate surface of the side end portion of the connector side connection portion is positioned so as to be able to come into contact with a surface perpendicular to the plate thickness direction of the connector side connection portion of the inner wall surface forming the support groove portion. Movement of the portion in the plate thickness direction is restricted. As a result, the connector side connecting portion can be positioned in the cover width direction and the plate thickness direction, and the connection work of the conductive strip terminal with the conductive strip side connecting portion is facilitated.

  In the first invention, the housing portion of the first cover member opens on one side in the longitudinal direction of the conductive strip and faces the engagement flat surface formed on the outer periphery of the bolt head or nut. The inner wall surface of the housing portion may be formed as a rotation prevention surface that engages with the engagement flat surface and prevents rotation of the bolt or the nut around the axis.

  By accommodating the housing portion of the first cover member on one side in the longitudinal direction of the conductive strip, the bolt head or nut can be accommodated from the side where the housing portion is open in the longitudinal direction of the conductive strip. Can do. In particular, when accommodating the head of the bolt, while maintaining the state where the bolt is inserted through the connector side connection portion, the head of the bolt is accommodated in the accommodation portion in the longitudinal direction of the conductive strip. The connecting portion can be brought to a support position on the first cover member.

  Further, since the engaging flat surface of the bolt head or nut accommodated in the accommodating portion engages with the rotation preventing surface of the accommodating portion, rotation around the bolt or nut axis is prevented. And the work of fastening the nut becomes easy.

  In the first invention, the first cover member has a support portion for supporting the housing of the electrical connector, and the second cover member has an engagement portion that can be engaged with the housing. The second cover member is attached to the first cover member while the engagement portion of the second cover member is engaged with the housing while the support portion of the first cover member supports the housing. Thus, the protective cover covers the connection portion between the connector side connection portion and the conductive strip side connection portion.

  In a state where the attachment of the protective cover is completed as described above, the support portion of the first cover member supports the housing, and the engagement portion of the second cover member is engaged with the housing. As a result, since the electrical connector is positioned with respect to the protective cover, the connection state of the connection portion between the connector-side connection portion and the conductive strip-side connection portion can be favorably maintained.

<Second invention>
The assembly of the electrical connector with a conductive strip and the protective cover according to the second invention includes a protective cover according to the first invention, an electrical connector for a power source provided with a connector terminal, and a conductive strip connected to the connector terminal. A conductive strip provided on one end side of the body terminal, the protective cover being a part of the connector terminal and projecting from the housing of the electrical connector; and the conductive strip. The plate-like conductive strip side connection part forming a part of the terminal is overlapped in the plate thickness direction of both connection parts and formed by fastening with bolts and nuts from both sides in the plate thickness direction It is characterized by covering the connecting part.

  As described above, in the present invention, since the entire connecting portion between the connector side connecting portion of the connector terminal and the conductive strip side connecting portion of the conductive strip terminal is covered with the protective cover, sufficient protection of the connecting portion is achieved. . In addition, the connection between the connector terminal and the conductive strip terminal is easy because the conductive strip terminal and the conductive strip do not rotate significantly around the bolt axis due to the tightening torque during the bolt and nut fastening process. It becomes. Further, in the above fastening process, the connection work becomes easier by accommodating and supporting the head or nut of the bolt in the accommodating portion of the first cover member. Furthermore, since the rotation of the conductive strip terminal and the conductive strip is restricted even after the bolt and the nut are fastened, a good connection state of the connection portion can be maintained.

  Next, the structure of the connector 1, the cable 4 with a terminal, and the protective cover 5 which comprise the said assembly is demonstrated in order. First, the configuration of the connector 1 will be described mainly based on FIG. 3 and FIG. FIG. 3 is a perspective view showing the protective cover 5 of the assembly in a state where a second cover member 60 described later is separated. 4 is a cross-sectional view of the connector 1 of FIG. 3, showing a cross section in a plane perpendicular to the connector width direction at a position slightly shifted from the center position in the connector width direction to the diagonally upper right in FIG. Yes. The connector 1 includes a housing 10 having a substantially rectangular parallelepiped outer shape, a connector terminal 20 that is partially accommodated in the housing 10, and a retainer 30 that is accommodated in the housing 10 and holds the connector terminal 20. The front half of the connector 1 forms a fitting portion that is fitted forward into the receiving portion 111 of the mating connector 101.

  As is often seen in FIG. 4, the space in the housing 10 is divided into two in the front-rear direction by an intermediate wall 11 formed at an intermediate position in the front-rear direction (left-right direction in FIG. 4). The intermediate wall 11 is formed with a through-hole portion 11A penetrating the intermediate wall 11 in the front-rear direction at the center in the vertical direction. The through-hole portion 11A is formed to be slightly larger than a later-described lateral plate portion of the connector terminal 20 in the connector width direction, and the lateral plate portion of the connector terminal 20 is inserted from the rear as seen in FIG. Yes. A space in front of the intermediate wall 11 (leftward in FIG. 4) is formed as a receiving portion 12 that receives the fitting portion of the mating connector 101 from the front, and is rearward of the intermediate wall 11 (rightward in FIG. 4). ) Is formed as a retainer accommodating portion 13 that receives and retains the retainer 30 from the rear. The receiving portion 12 and the retainer accommodating portion 13 communicate with each other through the through hole portion 11 </ b> A of the intermediate wall 11.

  The receiving portion 12 protrudes forward from the intermediate wall 11 and extends in the connector width direction (a direction perpendicular to the paper surface of FIG. 4) to support the contact plate portion 21 of the connector terminal 20 in the vertical direction. It is divided into two. The support plate portion 14 is opened in the vertical direction at a position corresponding to the contact portion of the mating connector terminal 120 in the connector width direction, and the upper surface of the contact plate portion 21 accommodated and supported by the support plate portion 14. And the lower surface is exposed.

  As shown in FIG. 4, from the rear surface of the intermediate wall 11, a locking arm portion 15 that can be elastically deformed in the vertical direction extends rearward from the upper end position and the lower end position. The locking arm portion 15 can be elastically deformed within a gap formed between the upper wall and the lower wall of the housing 10. Further, at the rear ends of these two locking arm portions 15, locking protrusions 15 </ b> A that protrude so as to approach each other in the vertical direction are formed. As will be described later, when the locking protrusion 15A is locked to the rear surface of the retainer 30, the retainer 30 and the connector terminal 20 supported by the retainer 30 are prevented from coming out backward.

  As is often seen in FIG. 3, prismatic engagement protrusions 16 are formed on the upper surface of the rear end portion of the housing 10 so as to protrude upward at three positions in the connector width direction. The engagement protrusion 16 is adapted to engage with an engagement hole 62A formed in a second cover member 60 described later of the protective cover 5 (see FIGS. 1, 2 and 7B). .

  The housing 10 has lock arm portions 17 that extend rearward at the both end positions in the connector width direction and can be elastically deformed in the connector width direction. The lock arm portion 17 is formed with two lock protrusions 17A that protrude outward in the connector width direction at an intermediate position in the front-rear direction and arranged in the vertical direction. The locking protrusion 17A is engaged with the above-described locked hole portion 114 formed at the rear end portion of the mating connector 101 in the connector fitting state, thereby preventing inadvertent disconnection between the connectors. .

  Further, an operation portion 17B for receiving the unlocking operation is formed at the rear end portion of the lock arm portion 17 so as to protrude outward in the connector width direction. When the connectors are pulled out, the operation portion 17B receives a pressing force (unlocking operation force) directed inward in the connector width direction, and the lock arm portion 17 is elastically deformed inward in the connector width direction. As a result, the locking projection 17A is disengaged from the locking position with the locked hole 114, and the connector 1 can be pulled out rearward.

  In the present embodiment, in a state where the connector 1 is supported by the protective cover 5, the front end position of the operation portion 17B of the connector 1 is coincident with the front end position of a support portion 51A described later of the protective cover 5, A portion in front of the operation portion 17B of the connector 1, that is, a portion protruding forward from the protective cover 50 forms a fitting portion to be inserted into the receiving portion 111 of the mating connector 101.

  The connector terminal 20 is made by bending a metal plate member at a right angle in the plate thickness direction, and has a horizontal L shape when viewed in the connector width direction as seen in FIG. The connector terminal 20 includes a horizontal plate portion that extends in the front-rear direction within the housing 10 and a vertical plate portion that protrudes outside the housing 10 and extends downward along the rear surface of the housing 10.

The latter half portion (the right half portion in FIG. 4) located in the retainer accommodating portion 13 is formed as a supported portion 22 supported by the retainer 30. The contact plate portion 21 is in contact with the contact portion formed on the mating connector terminal 120 with a contact pressure in a fitted state with the mating connector 101. The supported portion 22 is formed with a supported hole portion 22A penetrating in the plate thickness direction (vertical direction), and a later-described support protrusion 32 of the retainer 30 is inserted into the supported hole portion 22A from above. Thus, the retainer 30 is supported.

  The said vertical board part is formed as the connector side connection part 23 to which the cable terminal 40 of the cable 4 with a terminal is connected. The connector side connection portion 23 is formed with a connection hole portion 23 </ b> A penetrating in the plate thickness direction (front-rear direction) of the connector side connection portion 23 at a position near the lower end, and between the connector side connection portion 23 and the cable terminal 40. At the time of connection, the bolt 7 (see FIG. 6B) is inserted through the connection hole 23A from behind.

  As shown in FIG. 4, the retainer 30 is accommodated in the retainer accommodating portion 13 of the housing 10. The retainer 30 includes a base portion 31 extending in the front-rear direction and the connector width direction along the supported portion 22 above the supported portion 22 of the connector terminal 20, and a lower surface of the base portion 31 at an intermediate position in the front-rear direction of the base portion 31. A support protrusion 32 that protrudes downward from the base 31 and supports the supported part 22, and a protrusion 33 that protrudes from the upper surface of the base 31 at the same position as the support protrusion 32 in the front-rear direction.

  At the lower end of the support protrusion 32, a lower locked portion 32 </ b> A that is locked to the locking protrusion 15 </ b> A of the lower locking arm portion 15 on the lower side of the housing 10 is formed on the rear surface of the lower end. Further, the protruding portion 33 is formed with an upper locked portion 33 </ b> A for locking to the locking protrusion 15 </ b> A of the locking arm portion 15 on the upper side of the housing 10 on the rear surface. When the lower locked portion 32A and the upper locked portion 33A are locked with the locking protrusion 15A of the locking arm portion 15, respectively, the retainer 30 moves rearward, and thus the retainer 30 from the housing 10 and The connector terminal 20 is prevented from coming off.

  In the connector 1 having such a configuration, the horizontal plate portion of the connector terminal 20 is maintained while the support protrusion 32 of the retainer 30 is inserted into the supported hole portion 22A of the supported portion 22 of the connector terminal 20 from above. Assembling is performed by inserting the contact plate portion 21 and the supported portion 22 and the retainer 30 into the housing 10 from behind and attaching the retainer 30 to the housing 10. In the process of inserting the horizontal plate portion of the connector terminal 20 and the retainer 30, the lower latched portion 32 </ b> A of the retainer 30 and the upper latched portion 33 </ b> A of the protruding portion 33 are engaged with the latch arm 15 of the housing 10. Further insertion is possible by abutting against the protrusion 15A and elastically deforming so as to push the locking arm portions 15 apart. When the support protrusion 32 and the protrusion 33 of the retainer 30 reach the front of the locking protrusion 15A of the locking arm 15, the locking arms 15 return to the free state, and the locking protrusions 15A. As described above, the retainer 30 and the connector terminal 20 are prevented from coming off from the housing 10 by being positioned so as to be engageable with the lower locked portion 32A and the upper locked portion 33A.

  The insertion of the horizontal plate portion of the connector terminal 20 and the retainer 30 is completed when the front end of the retainer 30 comes into contact with the rear surface of the intermediate wall 11, and as a result, the assembly of the connector 1 is completed. When the connector 1 is assembled, the contact plate portion 21 of the connector terminal 20 is accommodated and supported by the support plate portion 14 in the receiving portion 12 as shown in FIG. 4 after passing through the through hole portion 11A of the intermediate wall 11.
