Description

  The present invention relates to a battery terminal.

  Conventionally, what was described in patent document 1 is known as an example of the battery terminal used in order to connect an electric wire to the battery post which is an electrode of a battery.

  This battery terminal includes an annular post holding portion that fits into a battery post of a battery mounted in an engine room of a vehicle, a fastening portion for fastening the post holding portion, and a terminal on the electric wire side. It is comprised from the electric wire connection part made to connect. The tightening portion extends from both ends of the post holding portion so as to be tightened by a post tightening bolt and a nut. The wire connection part is formed continuously on the opposite side of the post-clamping part and the stud bolt is provided so as to protrude upward, and the axis of the stud bolt is parallel to the axis of the battery post. It has become. An electric wire side terminal is inserted into the stud bolt, and a nut is inserted from above the terminal bolt and fixed by tightening. The battery post is located on the upper surface of the battery and has a substantially truncated cone shape having a tapered side surface with a diameter gradually decreasing from the upper surface toward the upper end side.

  In order to attach such a battery terminal, first, a post holding portion is fitted into the battery post from above, and a post fastening bolt is tightened and fixed. Next, the electric wire side terminal is inserted into the stud bolt of the electric wire connection portion, and the nut is tightened from above, thereby fixing the electric wire side terminal to the electric wire connection portion.

  However, according to such an attachment procedure, when the electric wire side terminal is fastened to the stud bolt of the electric wire connecting portion, the rotational torque acts on the battery terminal by the frictional force between the nut and the nut. Conventionally, this rotational torque has a relationship in which each axis of the stud bolt and the battery post is substantially parallel. Therefore, the rotational torque acting on the battery terminal around the stud bolt is substantially perpendicular to the axis of the battery post. Act on. As a result, a large force acts on the battery post in such a direction as to try to knock it down, and the battery post may be damaged when an excessive torque is applied.

  As a means to prevent this excessive torque from being applied to the battery post, the post holding part and the electric wire connecting part are configured separately, and both members are rotatably connected to the post holding part. It is conceivable that excessive torque applied to the wire connection portion is not directly transmitted.

  However, in such a state where the wire connecting portion is rotatably connected to the post holding portion, the battery terminal after the assembly is completed is rotated by vibration or the like while the vehicle is running, and an abnormal noise is generated. There is a risk.

  This invention is completed based on the above situations, Comprising: It aims at providing the battery terminal which can control rotation of the electric wire connection part with respect to a post holding part.

Has a post holding portions to be connected is fitted on the battery post erected on the battery itself, the stud bolt above the post holding portion are formed separately by wire-side terminals are connected by a nut fastening A terminal main body having a wire connecting portion and a rotation connecting portion that rotatably connects the wire connecting portion to the post holding portion, and the electric wire by engaging with the terminal main body. It can be installed after the side terminal is connected, and part is in contact with the wire connection part, and the other part is attached in contact with the stationary part in a state where relative movement is restricted with respect to the battery body or the battery body. And a rotation restricting member capable of switching the wire connecting portion connected to be rotatable to a rotation restricting state .

  According to such a structure, rotation with respect to the post holding part of an electric wire connection part can be switched to a rotation control state by the operation | work of attachment of a rotation control member. That is, at the time of wire connection work where an external force is applied to the wire connection portion, the wire connection portion can be rotated with respect to the post holding portion without attaching the rotation restricting member. It is possible to make a structure in which the external force applied to is difficult to be transmitted to the post holding portion. Then, after the battery terminal mounting operation is completed, by attaching the rotation restricting member, the electric wire connecting part is in a state in which the electric wire connecting part is restricted from rotating with respect to the post holding part. Therefore, it is possible to prevent abnormal noise generated by unnecessary rotation.

The following configuration is desirable as an embodiment of the present invention.
(1) The electric wire connecting portion is configured such that a stud bolt for fixing the electric wire is erected on a bolt holding portion having a rectangular tube shape having an opening on a side opposite to the post holding portion, and the rotation is performed. The restricting member is inserted into the bolt holding part from the opening and engages with the bolt holding part, and the restriction member is provided integrally with the elastic engaging claw and extends along the side surface of the battery body. A projecting portion; and a battery abutting portion provided in the extending portion and in contact with the side surface of the battery body. With such a configuration, the rotation restricting member can be easily attached even after the terminal body is attached to the battery post and the electric wire is connected to the electric wire connecting portion. Moreover, since the rotation restricting member can be attached using the structure of the terminal main body and the battery main body, it can be easily applied to existing shapes.

(2) The battery contact portion includes a pressing member inserted into a mounting hole formed in the extension portion, and the pressing member contacts the battery main body, and the battery main body. An elastic lock piece is integrally provided so as to be able to advance and retreat from a standby position that is separated from the holding portion, and to hold the pressing member at the contact position and the standby position with respect to the extending portion.

  According to such a configuration, the rotation restricting member can be brought into non-movable contact with the wire connecting portion and the battery body by the pressing member. Specifically, when the wire connection portion is about to rotate, a certain degree of rotation is restricted by the extension portion that is fixed to the wire connection portion via the elastic engagement pawl against the battery body. However, it does not prevent abnormal noise. In addition, since the extension part can be made immovable with respect to the battery body by bringing the pressing member into contact with the battery body, the rotation of the wire connection part is not only restricted, but also the rotation. Abnormal noise due to the attachment of the movement regulating member can also be prevented. In addition, the rotation restricting member can be attached to the electric wire connecting portion while the pressing member is held at the standby position of the mounting hole, and the handleability as the rotation restricting member is excellent.

(3) The electric wire connecting portion is formed by standing a stud bolt for fixing the electric wire on a bolt holding portion having a rectangular tube shape having an opening on the opposite side to the post holding portion, and The dynamic connecting portion includes a connecting shaft that connects a bottom plate portion integrally extending from the post holding portion and the bolt holding portion of the electric wire connecting portion, and the rotation restricting member includes the bolt An elastic engagement claw inserted into the holding portion from the opening and engaged with the bolt holding portion, an extension portion provided integrally with the elastic engagement claw, and the bottom plate portion provided in the extension portion A terminal abutting portion in contact with. The rotation restricting member is not necessarily in contact with the battery main body, and may be in contact with the bottom plate portion provided integrally with the other-side post holding portion to which the wire connecting portion is rotatably connected. According to such a configuration, the rotation restricting member can be applied regardless of the shape of the battery body.

(4) The terminal contact portion includes a pressing member inserted into a mounting hole formed in the extension portion, and the pressing member has a contact position that contacts the bottom plate portion, and the bottom plate portion. An elastic lock piece is integrally provided so as to be able to advance and retreat from a standby position that is separated from the holding portion, and to hold the pressing member at the contact position and the standby position with respect to the extending portion. According to such a configuration, similar to the configuration of the battery contact portion described above, it is possible to prevent the generation of abnormal noise due to the extension portion hitting the bottom plate portion. Moreover, since the pressing member can be held in the mounting hole, the handleability as the rotation restricting member is excellent.

(5) The electric wire connecting portion is formed by standing a stud bolt for fixing the electric wire on a rectangular tube-shaped bolt holding portion, and the stationary portion is the post holding portion, and the rotation restriction The member has an arc concave surface portion that can be contacted along the outer peripheral surface of the post holding portion, and an abutting surface that can abut on the bolt holding portion of the electric wire connecting portion. That is, the rotation restricting member is attached in contact with the outer side surfaces of the post holding portion and the bolt holding portion so as to be sandwiched between the post holding portion and the bolt holding portion. Thus, by using the rotation restricting member that can be attached using the shape of the terminal main body, the shape can be simplified, which can contribute to cost reduction. Further, since the rotation can be restricted using only the structure of the terminal body, the present invention can be applied regardless of other forms such as a battery body. Furthermore, by adopting a configuration in which the rotation restricting member is attached using the space between the post holding portion and the bolt holding portion, the rotation restricting member does not protrude on the outer periphery of the terminal body, and space saving is achieved. Is possible.

(6) The terminal body includes a bottom plate portion integrally extended from the post holding portion toward the wire connection portion, and the rotation restricting member is engaged with both side portions in the width direction of the bottom plate portion. A pair of mating elastic engagement pieces is formed. According to such a structure, the rotation restricting member can be held so as not to be pulled out with respect to the bottom plate portion.

(7) The rotation restricting member is provided integrally with a battery cover that covers the terminal body. By providing the rotation restricting member integrally with the battery cover, it is possible to prevent an error in the mounting order of the rotation restricting member or forgetting to attach it. If the rotation restricting member is attached before attaching the electric wire to the electric wire connecting portion by mistake, the external force applied to the electric wire connecting portion is transmitted to the post holding portion via the rotation restricting member, and the rotation is performed. The function of the connecting part is not demonstrated. Also, if you forget to attach the rotation restricting member to the terminal body, the wire connection part will be able to rotate with respect to the post-holding part even after the battery terminal has been attached, preventing abnormal noise from hitting other parts. I can't. In order to prevent such a situation, if the rotation restricting member is provided integrally with the battery cover, the rotation restricting member can be securely attached to the terminal body after the electric wire is attached to the wire connecting portion. Can be installed.

  ADVANTAGE OF THE INVENTION According to this invention, the battery terminal which can control rotation of the electric wire connection part with respect to a post holding part can be provided.

  A flat tab portion 23 extends from the bottom surface of the bolt holding portion 21 toward the holding portion 12 side. The post holding portion 12 and the electric wire connecting portion 20 are electrically connected by sandwiching the tab portion 23 between the elastic connecting piece 18 </ b> A and the bottom plate portion 17. The electric wire connecting portion 20 is connected to the post holding portion 12 by a connecting member 25 described later. When the electric wire connecting portion 20 rotates about the connecting member 25 as an axis, the tab portion 23 is also connected. It can be rotated within a predetermined range.

  The bottom plate portion 17 and the wire connecting portion 20 extending from the post holding portion 12 are connected to each other via a connecting member 25 so as to be rotatable (corresponding to a rotating connecting portion). Both ends of the connecting member 25 have large diameters, and are held in a state where they are inserted through the electric wire side holding holes provided in the bolt holding holes 21 and the post side holding holes of the bottom plate portion 17 so as not to be pulled out. . For this reason, the connecting member 25 is prevented from coming off in the axial direction, but is allowed to rotate in each holding hole (not shown).

Next, a description will be given of the rotation restricting member 30 that can be attached to the bolt holding portion 21 of the electric wire connecting portion 20 after the post holding portion 12 of the terminal main body 11 is externally fitted to the battery post 52.
As shown in FIGS. 5 and 6, the rotation restricting member 30 is inserted into the bolt holding portion 21 and engaged with the elastic engaging portion 31. The rotation restricting member 30 is orthogonal to the elastic engaging portion 31. It is comprised from the extension part 32 extended along the side part of this, and the battery contact part 33 provided on the extension part 32. As shown in FIG.

  The extending portion 32 extending from the elastic engagement portion 31 is flat and has a shape bent from the end of the elastic engagement portion 31 in a substantially right angle direction along the side surface of the battery body 51. Yes. The extension portion 32 is fixed to the battery body 51 in a state where the battery contact portion 33 provided on the extension portion 32 is in contact with the battery body 51.

  The battery contact portion 33 includes a mounting hole 34 that is opened at a substantially intermediate position in the extending direction of the extending portion 32, and a pressing member 35 that is inserted into the mounting hole 34. The pressing member 35 includes a lid portion 35A having a substantially rectangular shape, a pair of elastic lock pieces 35B projecting from both sides in the longitudinal direction of the lid portion 35A, and an inner side of the elastic lock piece 35B of the lid portion 35A. A pair of abutting pieces 35 </ b> C projecting and abutting against the battery main body 51 are provided.

  As shown in FIG. 7, the mounting hole 34 into which the pressing member 35 is inserted has a substantially rectangular groove-shaped lid receiving portion 34A into which the lid portion 35A is mounted, and the longitudinal direction of the bottom surface of the lid receiving portion 34A. A pair of engagement holes 34B penetrating the extension part 32 from both sides and an abutting hole 34C formed inside the engagement hole 34B and penetrating the extension part 32 are provided. An elastic lock piece 35B is inserted into the engagement hole 34B, and the engagement claws provided on the surfaces facing each other are engaged with each other to engage with each other. With this locking claw structure, the pressing member 35 is held in the mounting hole 34 so as to be able to advance and retreat from the standby position shown in FIG. 1 to the contact position shown in FIG. The contact hole 34C has a shape along the outer periphery of the contact piece 35C, and guides and inserts the insertion direction of the contact piece 35C. The contact piece 35C has a longer protruding length than the elastic lock piece 35B, and contacts the battery body 51 through the contact hole 34C in a state where the elastic lock piece 35B is engaged in the engagement hole 34B. .

  The present embodiment has the above-described structure, and the assembly work of the battery terminal 10 will be described next. First, the post holding part 12 is put on the battery post 52, and the nut 16 is fastened to the post fastening bolt 15 inserted through the bolt insertion hole 14. Thus, the post holding portion 12 is reduced in diameter toward the axial center of the battery post 52 and fixed to the battery post 52 in an externally fitted state.

  When the position of the battery terminal 10 with respect to the battery 50 is determined, the rotation restricting member 30 is attached to the wire connecting portion 20. A pressing member 35 is previously held in the standby position shown in FIG. 1 in the mounting hole 34 of the rotation restricting member 30. The elastic engagement portion 31 of the rotation restricting member 30 is inserted from the side of the bolt holding portion 21 opposite to the post holding portion 12. The elastic engagement claws 31 </ b> A are engaged with each other so as not to be pulled out by being caught on the edge portions on both sides in the width direction on the surface side facing the post holding portion 12 of the bolt holding portion 21. At this time, the extension part 32 is in a state of being arranged in parallel to the side surface of the battery body 51.

  Subsequently, an unillustrated wire-side terminal insertion hole is inserted into the stud bolt 22 held in a state of protruding from the bolt holding portion 21, and a not-illustrated nut is tightened from above to insert the unillustrated wire-side terminal into the electric wire. It is attached to the connecting part 20. At this time, a rotational torque in the direction a shown in FIG. 1 is applied to the stud bolt 22 side, and the extending portion 32 of the rotation restricting member 20 contacts the battery body 51. The nut can be tightened in a state where the bolt holding portion 21 is fixed to the battery body 51. The external force applied to the wire connection portion 20 when the nut is fastened is transmitted to the battery body 51 in which the bolt holding portion 21 is prevented from rotating through the extension portion 32, but can be rotated with respect to the wire connection portion 20. It is not transmitted to the post-holding unit 12 connected to. As a result, it is possible to eliminate the problem of damage to the battery post due to the transmission of external force to the post holding portion 12 that occurs when the electric wire connecting portion and the post holding portion are provided integrally, for example. .

  After the electric wire is connected to the electric wire connecting portion 20, the rotation restricting member 30 is fixed to the battery body 51 in order to restrict the electric wire connecting portion 20 from rotating unnecessarily. Specifically, the pressing member 35 held in the mounting hole 34 is pushed to the contact position in FIG. 4 and is locked in a state where the contact piece 35 </ b> C is pressed against the battery body 51. Thereby, the rotation restricting member 30 is not only held against the battery main body 51 but also functions as a detent for the electric wire connecting portion 20 to which the rotation restricting member 30 is attached.

  According to the structure as described above, the wire connecting portion 20 that is rotatably connected to the post holding portion 12 can be switched to the rotation restricted state by attaching the rotation restricting member 30. More specifically, first, at the time of connection work of an electric wire in which an external force is applied to the electric wire connecting part 20, the rotation restricting member 30 is attached to the electric wire connecting part 20, but is not applied to the battery body 51. Since it is not carried out, the electric wire connection part 20 can be rotated with respect to the post holding part 12. As a result, if the wire-side terminal is nut-fastened to the stud bolt 22 in a state in which the bolt holding portion 21 is prevented from rotating by bringing the extension portion 32 into contact with the battery body 51, the post torque of the rotational torque applied to the stud bolt 22 is obtained. Transmission to the holding portion 12 can be suppressed, and therefore damage to the battery post 52 can be prevented.

  Subsequently, after the electric wire is attached to the electric wire connecting portion 20, when the pressing member 35 of the rotation restricting member 30 is pushed to the contact position and is held against the battery main body 51, the electric wire is connected via the rotation restricting member 30. The connection unit 20 is fixed to the battery body 51. Thereby, generation | occurrence | production of the noise by the electric wire connection part 20 and the rotation control member 30 after an assembly | work operation | work turning unnecessary by the vibration at the time of vehicle travel, etc. can be prevented. As described above, since the wire connection part 20 can be switched between the rotatable state and the non-rotatable state depending on the situation where the wire connection part 20 is placed, the external force is not transmitted from the wire connection part 20 to the post holding part 12. The generation of abnormal noise due to the structure can be prevented.

  Further, the rotation restricting member 30 of the present embodiment can be attached or detached without using a tool by using the existing structure of the terminal main body 11, and is excellent in handleability. In addition, the rotation restricting member 30 can be attached to the electric wire connecting portion 20 with the pressing member 35 held at the standby position, and can be easily switched to the battery main body 51, so that it is easy to use. .

  As mentioned above, although Embodiment 1 of this invention was shown, this invention is not restricted to the said embodiment, For example, the following modifications can also be included. In the following modifications, members similar to those in the above embodiment are denoted by the same reference numerals as those in the above embodiment, and illustration and description thereof may be omitted.

  A terminal abutting portion 36 is provided at a position corresponding to the bottom plate portion 17 of the extending portion 32 constituting the rotation restricting member 30. The terminal contact portion 36 includes a mounting hole 37 provided in the extending portion 32 and a pressing member 38 inserted and held in the mounting hole 37. The mounting hole 37 and the pressing member 38 have the same structure as the mounting hole 34 and the pressing member 35 of the first embodiment.

  After attaching the rotation restricting member 30 to the electric wire connecting portion 20 and connecting the electric wire to the electric wire connecting portion 20, the pressing member 38 held in the mounting hole 37 is pushed into the contact position in FIG. Cover and hold. Thereby, the rotation restricting member 30 and the wire connecting portion 20 can be fixed to the bottom plate portion 17 provided integrally with the post holding portion 12 via the pressing member 38.

  According to such a structure, the wire connecting portion 20 cannot rotate because the pressing member 38 of the rotation restricting member 30 contacts the bottom plate portion 17 that is rotatably connected by the connecting member 25. Can be fixed to. Moreover, since the length of the extension part 32 can be shortened by making the other party member which presses the pressing member 38 into the baseplate part 17, compared with Embodiment 1, weight reduction and cost. Reduction can be achieved. Further, when the pressing member 35 is brought into contact with the battery main body 51 as in the first embodiment, the battery post 52 is provided at a position where the extending portion 32 can be arranged along the side surface of the battery main body 51. It was necessary to make assumptions. On the other hand, according to the structure of the present modification, the pressing member 38 abuts against the bottom plate portion 17, so that it can be applied regardless of the shape of the battery body 51 and the position of the battery post 52 with respect to the battery body 51. Is possible.

A side surface of the main body 61 arranged on the post holding portion 12 side is an arc concave portion 61 </ b> A that has an arc shape along the outer peripheral shape of the post holding portion 12 that is externally fitted to the battery post 52. A side surface disposed on the bolt holding portion 21 side opposite to the arc concave surface portion 61 </ b> A is a contact portion 61 </ b> B that contacts the side surface of the bolt holding portion 21. The claw portions 63 project toward the inner side of the side plate portion 62, and are held on both side portions in the width direction of the bottom plate portion 17 to hold the rotation restricting piece 60 against the bottom plate portion 17 so as not to be pulled out.

  After inserting a wire-side terminal (not shown) into the wire connecting portion 20 and fastening the nut, the rotation restricting piece 60 is attached to the terminal body 11. Between the post holding portion 12 and the bolt holding portion 21, the circular arc concave surface portion 61 </ b> A is positioned and pushed in such a way as to contact the outer periphery of the post holding portion 12. Then, the side plate portion 62 having the claw portion 63 at the tip is elastically deformed, whereby the rotation restricting piece 60 is locked to the bottom plate portion 17.

  According to such a configuration, the rotation restricting piece 60 is fitted between the post holding portion 12 and the bolt holding portion 21 of the electric wire connecting portion 20, so that the electric wire connecting portion 20 can be rotated with respect to the post holding portion 12. The movement can be easily regulated. Thereby, like Embodiment 1, while utilizing the function of the rotation connection part which external force does not transmit from the electric wire connection part 20 to the post holding part 12, it can prevent the noise which generate | occur | produces because it has the structure. it can.

  Moreover, the structure of the terminal main body 11 is simplified as compared with the first embodiment by configuring the rotation connecting portion and the electrical connection between the post holding portion 12 and the wire connecting portion 20 using the louver terminal 42. Can be Thereby, the number of parts which comprise the terminal main body 11 can be suppressed, and it can contribute to material cost reduction. The rotation restricting piece 60 is attached between the post holding portion 12 and the wire connecting portion 20 so that the rotation restricting piece 60 does not protrude outward from the terminal body 11 and the space is effective. It is possible to utilize it.

  As mentioned above, although Embodiment 2 of this invention was shown, this invention is not restricted to the said embodiment, For example, the following modifications can also be included. In the following modifications, members similar to those in the above embodiment are denoted by the same reference numerals as those in the above embodiment, and illustration and description thereof may be omitted.

[Modification 1 of Embodiment 2]
A first modification of the second embodiment will be described with reference to FIGS. Here, the difference is that the rotation restricting portion 71 having the same structure as that of the second embodiment is provided integrally with the battery cover 70.

  The battery cover 70 is made of synthetic resin and is attached to the battery body 51 so as to cover the battery terminal 10 from above. The battery cover 70 is provided with a rotation restricting portion 71 that is sandwiched between the post holding portion 12 and the wire connecting portion 20 when the battery cover 70 is attached to the battery terminal 10. The rotation restricting portion 71 is substantially columnar, and has an arc concave surface 72 that abuts on the arc-shaped side surface of the post holding portion 12 and a contact that abuts on the side surface facing the post holding portion 12 of the bolt holding portion 21. And a surface 73. The lower end portion of the rotation restricting portion 71 has a concave shape at a substantially central position so that the bottom plate portion 17 of the terminal body 11 can be inserted and can contact the battery body 51.

  According to such a structure, in addition to the effects of the second embodiment, it is possible to prevent an error in the mounting order of the rotation restricting portion 71 and forgetting to mount it. More specifically, when connecting an electric wire to the electric wire connecting portion 20, for the same reason as in the first embodiment, the post holding portion 12 is prevented from transmitting an external force applied to the electric wire connecting portion 20 to the post holding portion 12. It is necessary to be able to rotate with respect to it. However, if, for example, the rotation restricting piece 60 of the second embodiment is attached to the electrical connecting portion 20 before the electric wire is attached, the electric wire connecting portion 20 is interlocked with the post holding portion 12 and both members are rotatably connected. Does not make sense. Further, there is a possibility that the battery cover 70 is attached without attaching the rotation restricting piece 60 which is a separate body from the terminal body 11. In order to prevent such a situation, if the rotation restricting portion 71 is provided integrally with the battery cover 70, the rotation restricting portion 71 can be surely forgotten after the electric wire is attached to the wire connecting portion 20. The terminal body 11 can be attached.
