Description

  The present invention relates to a temporary placement structure for a battery wire-side terminal that temporarily places a wire-side terminal on a battery side when the wire-side terminal is removed from a vehicle battery terminal for maintenance or the like.

  FIG. 4 shows one embodiment of a conventional battery wire side terminal connection structure (see Patent Document 1).

  In this structure, a case 33 made of an insulating resin covering the positive and negative terminals 32 of the battery 31 is provided in the upper part of the battery 31 of the automobile, and the vertical and vertical terminals that isolate the positive and negative terminals 32 in the center of the case 33. When a partition wall (not shown) is provided, a half-size slide lid 34 is slidably mounted in the upper opening of the case 33, and the terminals 35 on the electric wire side are connected to the positive and negative terminals 32, respectively. Then, the slide lid 34 is moved and connected in order of the positive electrode side and the negative electrode side, and when the terminal 35 on each electric wire side is detached from each terminal 32 of the positive electrode and negative electrode, the slide lid 34 is moved in reverse. Thus, a stopper (not shown) for preventing improper connection that abuts against the electric wire side terminal 35 is provided on the slide lid 34 so as to be detached in order of the negative electrode side and the positive electrode side.

  The reason why the positive and negative terminals 32 are connected and disconnected in the above order is, for example, that if the negative electrode terminal on the electric wire side is connected to the negative electrode terminal of the battery 31 first, the electric wire side is connected to the subsequent positive electrode terminal. This is because when a positive electrode terminal is connected, a metal tool or the like may come into contact with the ground to cause a short circuit.

  FIG. 5 shows a state in which the negative electrode (ground side) electric wire side terminal 8 is detached from the negative electrode terminal 2 of the conventional battery 1 as another embodiment.

  An electric wire (harness) 9 for grounding is connected at one end to a conductive metal vehicle body 12 at a terminal 10 and has a negative electrode terminal 8 at the other end. The negative terminal 8 has a circular taper-shaped through hole 8 a corresponding to the negative electrode terminal (battery post) 2 having a tapered column shape of the battery 1.

For example, when an operator removes the electric wire side terminal 8 for vehicle maintenance, transportation, storage, exhibition, etc., the electric wire side terminal 8 is placed on, for example, a battery tray 11 made of an insulating resin disposed under the battery 1. It is often carried out by hooking and temporarily placing.
Japanese Patent Laying-Open No. 2003-157828 (FIG. 6)

  However, in the conventional structure of FIG. 4, for example, when the negative electric wire side terminal 35 is removed from the battery 31 for maintenance or the like, both the positive and negative terminals 32 of the battery 31 are within the case 33. There is no fear of short-circuiting because it is partitioned, but there is a concern that a tool or the like may come into contact with the battery side terminal 32 on which the slide lid 34 is opened, and a mechanism for temporarily placing the wire side terminal 35 removed from the battery 31 Therefore, as shown in FIG. 5, there is only a method for hooking and holding the removed electric wire side terminal 8 on the battery tray 11 or the like. In addition, there is a problem that the structure is complicated and the cost is high only for the purpose of insulating and protecting the battery side terminal 32 after the electric wire side terminal 35 is removed.

  As shown in FIG. 5, when the electric wire side terminal 8 removed from the battery 1 is hooked on the battery tray 11 or the like and temporarily placed, the battery side terminal 8 is exposed. I was worried that it would cause a short circuit by touching. Further, since the battery connecting wire 9 has a large wire diameter and high rigidity, a restoring force is exerted when the wire 9 is bent, and the wire side terminal 8 hooked on the battery tray 11 or the like is detached from the battery tray or the like. There was a concern that it could come into contact with the side terminal 2 and cause malfunction or failure of the device.

  In view of the above points, the present invention provides a battery wire-side terminal temporary placement structure that can securely place a wire-side terminal removed from a battery with a simple structure and without the influence of restoring force when the wire is bent. The primary purpose is to provide In addition, a temporary placement structure for the battery wire side terminal is provided so that there is no risk of malfunction of the equipment due to the tool or wire side terminal coming into contact with the battery side terminal after the wire side terminal is removed. The second purpose is to do.

  With the above configuration, the electric wire side terminal is detached from the battery side terminal, the cap portion is covered with the battery side terminal to insulate the battery side terminal from the outside, and the cap portion is connected to the protruding portion connected by the plate portion with the electric wire side terminal. Temporarily hold. For example, the plate portion is locked (held) by the battery by bringing the side end of the plate portion into contact with the protrusion on the upper portion of the battery. If the battery side terminal is accommodated in the cap part without rattling, this locking (holding) is not necessary. The cap part and the projecting part are arranged in parallel on the same plate part, and the battery-side terminal and the projecting part in the cap part are positioned in parallel at substantially the same height.

  The temporary placement structure for the battery electric wire side terminal according to claim 3 is the temporary placement structure for the battery electric wire side terminal according to claim 2, wherein a hook portion to be engaged with the side surface of the battery is provided on the plate portion. It is characterized by that.

  With the above configuration, the cap portion is covered with the battery-side terminal, and at the same time, the hook portion is hooked on the side surface of the battery and locked, so that the insulating and temporary placing member including the cap portion, the projecting portion, and the plate portion is loosely attached to the battery. It is stably held without sticking, and the stability of temporary placement of the electric wire side terminal on the protrusion is increased. It is preferable to provide a pair of flanges at both ends of the plate. Even if there is only one hook part, the insulation and temporary placement member can be held by the battery at two points of the battery side terminal and the hook part in the cap part.

  The temporary placement structure of the battery wire-side terminal according to claim 4 is the temporary placement structure of the battery wire-side terminal according to any one of claims 1 to 3, wherein the protruding portion is gradually reduced in diameter toward the tip. It is characterized by being formed in a tapered shape.

  With the above configuration, in the case where the tapered hole portion of the electric wire side terminal is in close contact with the tapered column-shaped battery side terminal (post), the tapered hole portion of the electric wire side terminal is separated from the battery side terminal and protruded. The surface can be stably engaged with the surface contact without play.

  According to the first aspect of the present invention, the electric wire side terminal detached from the battery side terminal can be temporarily placed on the battery-side protruding portion with good workability without any electric wire bending reaction force. The disconnection of the electric wire side terminal due to the force can be prevented. As a result, the contact between the electric wire side terminal and the vehicle body or other parts and the accompanying damage are prevented, and the unexpected contact between the electric wire side terminal and the battery side terminal is prevented. Secured. Further, since the structure is simple, the cost can be reduced.

  According to the invention of claim 2, since the battery side terminal is covered and insulated by the cap portion, even if the wire side terminal is detached from the protrusion, it does not contact the battery side terminal, Or a metal tool etc. do not touch a battery side terminal, and safety | security at the time of a maintenance etc. is maintained more reliably. Moreover, since the cap part and the protrusion part are integrated by the plate part, insulation of the battery side terminal and temporary placement of the electric wire side terminal can be performed with good workability. In addition, the structure can be simplified and the cost can be reduced by integral resin molding or the like.

  According to invention of Claim 3, a plate part can be stably hold | maintained to a battery with a collar part, and insulation of the battery side terminal in a cap part and temporary placement of the electric wire side terminal to a protrusion are continued. Can be performed stably.

It can be detached from the terminal and can be stably engaged with the protrusion without rattling, which prevents the unintentional detachment of the wire side terminal from the protrusion and prevents damage due to the unexpected detachment of the wire side terminal. And concerns about contact with battery terminals are eliminated.

  1 to 2 show an embodiment of a temporary placement structure for a battery wire-side terminal according to the present invention.

  In this structure, an insulating hollow cap portion (accommodating portion that is an insulating portion) 3 that accommodates the negative electrode terminal 2 of the battery 1 of an automobile and an electric wire side terminal 8 that is detached from the negative electrode terminal 2 are engaged. Insulation / temporary placement member 7 made of an insulating resin comprising a solid projection (temporary placement portion) 4 and an insulating plate-like plate portion 5 in which the cap portion 3 and the projection 4 are projected upward. Is detachably attached to the upper part of the battery 1. “Insulation and temporary placement” means that the battery-side terminal 2 is insulated and the wire-side terminal 8 is temporarily placed.

  The cap part 3 is composed of a cylindrical vertical peripheral wall 3a and a horizontal top wall (upper wall) 3b that closes the upper end of the peripheral wall 3a, and is enclosed in a circular cross section surrounded by the peripheral wall 3a and the top wall 3b. There is a space 3c (FIG. 2), and the accommodation space 3c has a circular lower opening 3d (FIG. 2) opened to the outside from the bottom surface of the plate portion 5. The depth of the accommodating space 3c is slightly deeper than the height of the negative electrode terminal 2 of the battery 1, and the inner diameter of the accommodating space 3c is set slightly larger than the outer diameter of the large diameter portion 2a (FIG. 2) on the bottom side of the negative electrode terminal 2. ing.

  The protrusion 4 is formed in a size and shape substantially the same as the negative electrode terminal 2 of the battery 1. That is, when the negative electrode terminal 2 of the battery 1 has a tapered column shape, the protrusion 4 is formed in a tapered column shape that gradually decreases in diameter toward the tip, corresponding to the electric wire side terminal 8 that fits into the negative electrode terminal 2 of the battery 1. The The height of the protrusion 4 is higher than the thickness of the electric wire side terminal 8, and the outer diameter of the protrusion 4 supports the circular tapered hole 8 a of the electric wire side terminal 8 at the intermediate portion in the height direction. The outer diameter of the protrusion tip is set smaller than the minimum inner diameter of the hole 8a, and the outer diameter of the protrusion proximal end is set larger than the maximum inner diameter of the hole 8a.

  The electric wire side terminal 8 includes an annular portion 8b having a hole portion 8a and an electric wire connecting portion 8c following the annular portion 8b. The hole portion 8a is tightly fixed to the battery side terminal 2 by screw fastening means 8d. A terminal 8 on the battery connection side is connected and fixed to one end of the electric wire (harness) 8, and a terminal 10 on the vehicle body connection (ground) side is connected and fixed to the other end of the electric wire 9. A vehicle body made of conductive metal is denoted by reference numeral 12.

  The cap part 3 and the protrusion 4 are integrally molded with the plate part 5. It is also possible to form the protrusion 4 hollow (in this case, the strength of the protrusion 4 is sufficiently high and the inner diameter of the internal space is sufficiently small so that the negative electrode terminal 2 of the battery 1 cannot be erroneously inserted. is necessary).

  The plate portion 5 of the present example is suspended at the horizontal horizontally long plate portion (plate body) 5a having a length along the short side portion 1b of the rectangular upper end surface 1a of the battery 1 and the longitudinal front and rear ends of the plate portion 5a. It is comprised with the collar part 6 made. The cap part 3 and the protrusion 4 protrude from the plate part 5a. The pair of flange portions 6 are in contact with both side surfaces 1d following the lower side of the long side portion 1c of the upper end surface 1a of the battery 1, and together with the battery side terminal 2 engaged with the cap portion 3, are insulated and temporarily placed at three points. 7 is held stably so as not to be detached from the battery 1. The plate portion 5 a is placed on the upper end surface 1 a of the battery 1.

  As shown in FIG. 1, the cap 3 of the insulating and temporary holding member 7 is put on the negative electrode terminal 2 of the battery 1 with the electric wire side terminal 8 removed from the negative electrode terminal 2 of the battery 1. The flange 6 of the temporary placement member 7 is engaged with both side surfaces 1 d of the battery 1, and the insulation and temporary placement member 7 is held by the battery 1. In this state, the hole 8 a of the electric wire side terminal 8 is engaged with the protruding portion 4 of the insulating and temporary placement member 7. The battery side terminal 2 is insulated from the outside in the cap portion, and the electric wire side terminal 8 is temporarily placed without being detached from the protrusion 4.

  According to the embodiment of FIGS. 1 and 2, since the protrusion 4 is disposed relatively near the negative electrode terminal 2 of the battery 1, the electric wire side terminal is attached to the battery tray 11 or the body as in the conventional case (FIG. 5). 8 is no longer caught, and the conventional wire side terminal is unexpectedly disconnected due to the reaction force of the wire after being hooked, and the wire side terminal 8 and the vehicle body 12 due to this, the damage due to the contact between the body 12 and the parts close to the battery, etc. Concerns such as an unexpected contact between the electric wire side terminal 8 and the battery side terminal 2, and a contact between a metal tool or the like and the battery side terminal 2 are eliminated. Further, since the electric wire 9 is not forcibly bent or pulled for hooking as in the prior art, excessive stress is not applied to the electric wire 9 or the terminal 10 on the vehicle body connection side.

  Further, by engaging the tapered hole portion 8a of the electric wire side terminal 8 with the tapered columnar protrusion portion 4 of the insulating and temporary placement member 7, the electric wire side terminal 8 is stably held by the protrusion portion 4 by a wedge action. (Temporary placement) is ensured to prevent the wire-side terminal 8 from being temporarily removed.

  Even if the electric wire side terminal 8 is detached from the protrusion 4, the electric wire side terminal 8 is in contact with the battery side terminal 2 because the battery side terminal 2 is covered with the cap portion 3 of the insulating and temporary placement member 7. There is no worry. As a result, for example, the worry that the electrical components of the vehicle unexpectedly malfunction during maintenance is eliminated, and the safety is improved. This effect is reliably exhibited even when the vehicle body shakes.

  3 (a) and 3 (b) show another embodiment of the temporary placement structure of the battery wire side terminal according to the present invention. Components similar to those in the embodiment of FIG. 1 are denoted by the same reference numerals, and detailed description thereof is omitted.

  In this structure, a protrusion 4 ′ having a size and shape substantially the same as that of the negative electrode terminal (post) 2 of the battery 1 is formed on the upper wall 1 a of an insulating resin case (represented by reference numeral 1) of the battery 1 of the automobile. When the electric wire side terminal 8 is removed from the negative electrode terminal 2 of the battery 1 as shown in FIG. 3A, the electric wire side terminal 8 is protruded in parallel with the terminal 2 as shown in FIG. It is temporarily placed by engaging with '.

  Compared with the embodiment of FIG. 1 described above, there is no member 3 that insulates the negative electrode terminal 2 of the battery 1, but even with the structure of FIG. . The protrusion 4 'acts as a temporary placement member.

  The protrusion 4 ′ is preferably resin-molded integrally with the insulating resin case of the battery 1, but the separate protrusion 4 ′ can be fixed to the case with an adhesive or the like. When the battery 1 has a screw-tight cap (not shown) for injecting liquid, the protrusion 4 ′ can be formed integrally with the cap. As in the embodiment of FIG. 1, the protrusion 4 ′ is formed in a tapered shape like the negative electrode terminal 2 of the battery 1, in order to improve the retainability (temporary placement property) of the electric wire side terminal 8. preferable.

  The protrusion 4 ′ is arranged in parallel with the negative electrode terminal 2 along the short side 1 b of the upper end surface 1 a of the battery 1. When the position of the vehicle body side connection portion 10 of the electric wire 9 is not the short side 1b side but the long side 1c side of the battery 1, the negative electrode is formed along the long side portion 1 c from the viewpoint of ease of temporary placement of the electric wire 9. It is also possible to arrange the protrusion 4 ′ in parallel with the negative electrode terminal 2 in the vicinity of the terminal 2.

  This is the same in the embodiment of FIG. 1, and the plate portion 5 of the insulating and temporary holding member 7 is extended along the long side portion 1 c of the upper wall 1 a of the battery 1, and the flange portions at both ends of the plate portion 5. 6 may be engaged with the battery side surface on the short side 1b side, and the protrusion 4 may be provided in parallel with the cap portion 3 in the vicinity of the battery side terminal 2. In any case, providing the protrusions 4 and 4 ′ near the positive terminal (not shown) of the battery 1 is avoided because there is a risk of bringing the negative electric wire side terminal 8 into contact with the positive terminal of the battery 1. Better.

  According to the embodiment of FIG. 3, the protrusion 4 ′ is disposed relatively near the negative electrode terminal 2 of the battery 1, so that the electric wire side terminal 8 is attached to the battery tray 11, the vehicle body 12, etc. as in the prior art (FIG. 5). There is no worry about the unexpected disconnection due to the reaction force of the electric wire after the hooking of the conventional electric wire side terminal, or the damage caused by the collision between the electric wire side terminal and the vehicle body, parts densely located near the battery, etc. The worry of unexpected contact between the electric wire side terminal and the battery side terminal is eliminated. Further, since the electric wire 9 is not forcibly bent or pulled for hooking as in the prior art, excessive stress is not applied to the electric wire 9 or the terminal 10 on the vehicle body connection side.

  In addition, by engaging the tapered hole 8a of the electric wire side terminal 8 with the tapered columnar protrusion 4 ′, which is a temporary placement member, the electric wire side terminal 8 is stably held by the protrusion 4 ′ by the wedge action. (Temporary placement) is ensured to prevent the wire-side terminal 8 from being temporarily removed.

  The embodiment of FIG. 3 can be considered as a process leading to the embodiment of FIG. That is, the protrusion 4 ′ of the embodiment of FIG. 3 is not provided directly on the battery 1, but is provided on a separate plate portion 5, which is the basic structure of the embodiment of FIG. By providing the cap part 3 as an insulating part, the embodiment of FIG. 1 is completed.

  In each of the above embodiments, the protrusions 4 and 4 ′ are formed in a tapered shape corresponding to the tapered terminal 2 of the battery 1 (the tapered hole portion 8a of the electric wire side terminal 8). When the battery side terminal 2 has a straight column shape (the hole 8a of the electric wire side terminal 8 is straight), the protrusions 4 and 4 'can be formed into a straight column shape. Even in this case, if the tapered column-shaped protrusions 4 and 4 ′ are used, the hole 8a of the electric wire side terminal 8 is fitted in the annular line contact without gaps in the middle of the protrusions 4 and 4 ′, and is held well. be able to.

  Moreover, in each said embodiment, the terminal by the side of the battery 1 is a plate-shaped thing which has a hole part (not shown), and the terminal by which the terminal by the side of the electric wire 9 is screwed and joined to the plate-shaped part of a battery terminal When the battery-side terminal is a male screw type and the wire-side terminal is a plate-like terminal having a hole as in the conventional example of FIG. It is possible to cope with this by providing a straight columnar protrusion for inserting and engaging the hole of the electric wire side terminal as the temporary placement portion.

  Also in this case, if the tapered column-shaped ones 4 and 4 ′ are used as the protrusions, the hole portions of the electric wire side terminals can be fitted and held well in the middle of the protrusions 4 and 4 ′. The cap part (3) as an insulating part (accommodating part) corresponding to the example of FIG. 1 may have a space for accommodating a plate-like battery terminal or a male screw type battery terminal.

  In each of the above embodiments, the case where the grounding electric wire side terminal 8 is connected to and disconnected from the negative electrode terminal 2 of the battery 1 has been described. However, the electric power supply electric wire side terminal is connected to and disconnected from the positive electrode terminal of the battery 1. Even in this case, the same insulating and temporary placement member 7 and temporary placement member (protrusion) 4 ′ can be arranged or arranged on the battery side.

  In the embodiment shown in FIG. 1, the plate portion 5 is locked to the battery 1 by the pair of flange portions 6, but the flange portion 6 may be one instead of a pair. In this case, the flange portion 6 is not disposed near the cap portion 3 but at the end portion near the protrusion 4 so that the plate portion 5 has two points of the battery side terminal 2 and the flange portion 6 in the cap portion and a long span. Is preferable for stably supporting the battery on the battery.

  Further, for example, the flange portion 6 is eliminated, and the plate portion 5 is brought into contact with a protrusion or the like (not shown) on the upper part of the battery by bringing one end 5b or both ends of the plate portion 5 in the width direction (longitudinal orthogonal direction) It is also possible to lock 5 to the battery 1. Further, if the battery side terminal 2 is engaged in the cap portion 3 without rattling, these locking means are unnecessary.
