Description

  The present invention relates to a configuration of a battery post terminal assembly including a battery post terminal.

  Conventionally, a battery post terminal fixed to a battery post of a battery mounted on a vehicle is known. Patent Document 1 and Patent Document 2 disclose this type of battery post terminal.

  When the battery post terminal of Patent Document 1 is moved in a direction facing and approaching an annular portion formed with a battery post insertion hole that is in surface contact with the peripheral side surface of the battery post with a predetermined interval, the battery post insertion hole An electrical connection portion having a pair of tightening portions for reducing the diameter, a pair of bent portions formed by bending outward in a substantially L shape, and a plan view in which the upper surface is a seating surface of the stud bolt. Provided, and the seat surface height position of the flat surface portion is formed in the vicinity of the position of the lower surface of the annular portion. Patent Document 1 assumes that the height position of the seat surface of the stud bolt is lowered by this configuration, so that it does not interfere with other parts attached to the upper part of the battery post terminal.

  The battery post terminal of Patent Document 2 has a left and right extension part formed with an inclined surface, and an electrode fitting part that sandwiches the side surface of the battery post from both sides by pressing so that the left and right extension parts narrow. And a slope that has four leg portions, each of which has a slope having the same inclination angle as the inclined surface, and presses the left and right extension portions by moving up and down while contacting the slope with the inclined surface. A member and a bolt for moving the slope member up and down, and the battery post terminal is viewed from the vertical direction, and the four leg portions are arranged at intervals along the outer periphery of the screw portion with the screw portion at the center.

JP2015-11792A International Publication No. 2014/129534

  In the configuration of Patent Literature 1, when the battery post is tightened, the upper bracket and the lower bracket that are in contact with each other so as to sandwich the battery post terminal from both sides come into contact with the battery post terminal in a small area. Therefore, the tightening force becomes local, and it is difficult to uniformly tighten the battery post terminals. Further, in the configuration of the above-mentioned Patent Document 1, only the upper bracket and the lower bracket are inclined on the surface where the battery post terminal contacts the upper bracket and the lower bracket (the battery post terminal is not inclined). ). Therefore, there is room for improvement in that the durability of the battery post terminal becomes insufficient due to insufficient tightening force of the battery post terminal or the battery post terminal biting into the upper bracket and the lower bracket side.

  Moreover, in the structure of the said patent document 2, an inclined surface is formed only in a slope member among the slope members and bolts which contact so that a battery post terminal may be pinched | interposed from both sides, and when this battery post is tightened, this inclined surface Generates a clamping force by contacting the battery post terminal. Therefore, there is room for improvement in that the clamping force is easily biased and the battery post terminal strongly bites the slope member and it is difficult to loosen it.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a battery post terminal assembly capable of fixing a battery post terminal to a battery post with sufficient tightening force in a well-balanced manner.

The grip portion can grip the battery post inside. The tightening portions are arranged in pairs so as to extend from the end of the gripping portion. The first taper member is disposed on one side of the tightening portion. The second taper member is disposed on the opposite side of the first taper member with the tightening portion interposed therebetween. The first taper member and the second taper member are connected to each other via a tightening screw structure. The first taper member is formed with a first taper surface inclined with respect to the direction of the screw shaft of the tightening screw structure. The second taper member is formed with a second taper surface inclined in a direction opposite to the first taper surface with respect to the direction of the screw shaft of the tightening screw structure. Each of the tightening portions is formed with a first inclined surface and a second inclined surface. The first inclined surface is formed in a direction corresponding to the first tapered surface and can contact the first tapered surface. The second inclined surface is formed in a direction corresponding to the second tapered surface, can contact the second tapered surface, and is inclined in a direction opposite to the first inclined surface.

  As a result, the battery post can be tightened by applying force to the tightening portion while dispersing the force between the two sets of tapered surfaces and the inclined surface, so that the taper member locally bites into the tightening portion, thereby improving durability. It can be prevented from lowering.

  In the battery post terminal assembly, in each of the tightening portions, the first inclined surface is closer to the grip portion than the second inclined surface, and the second inclined surface as viewed from the grip portion. It is preferable that they are arranged on both the far side and the far side.

  The battery post terminal assembly preferably has the following configuration. That is, the first taper member is formed with a pair of first protrusions that protrude in a direction approaching the second taper member. The second taper member is formed with a pair of second protrusions protruding in a direction approaching the first taper member. The first tapered surface is disposed on a surface of the first protrusion facing the tightening portion. The second tapered surface is disposed on a surface of the second protrusion facing the tightening portion.

  Thereby, it can clamp | tighten with a simple structure, distributing force.

  The battery post terminal assembly preferably has the following configuration. That is, four first protrusions are formed. Two second protrusions are formed. Each of the second protrusions is inserted between two of the four first protrusions.

  Thereby, a 1st taper member and a 2nd taper member can be arrange | positioned compactly.

  The battery post terminal assembly preferably has the following configuration. That is, the first tapered surface is inclined to one side with respect to the direction of the screw shaft of the tightening screw structure. The second tapered surface is inclined in the direction opposite to the first tapered surface at substantially the same angle as the inclination angle of the first tapered surface with respect to the direction of the screw shaft of the tightening screw structure.

  As a result, the tightening force can be applied evenly without causing any bias.

  In the battery post terminal assembly, it is preferable that the screw shaft of the tightening screw structure is disposed in parallel with the central axis of the battery post.

  As a result, a compact arrangement around the battery post can be realized, and the work of tightening or loosening the tightening screw structure can be simplified.

  In the battery post terminal assembly, it is preferable that irregularities are formed on the inner surface of the grip portion.

  Thereby, the battery post can be gripped strongly.

  Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view illustrating a state in which a battery post terminal assembly 3 according to an embodiment of the present invention is attached to a battery post 2. FIG. 2 is a perspective view showing the overall configuration of the battery post terminal assembly 3. FIG. 3 is an exploded perspective view of the battery post terminal assembly 3.

  As shown in FIGS. 1 and 2, the battery post terminal assembly 3 includes a battery post terminal 4, a holder member (first taper member) 5, a base member (second taper member) 6, a nut 7, It has.

  As shown in FIG. 1, the battery post terminal 4 is a terminal that is arranged in an engine room such as a vehicle and connects the battery post 2 of the battery 1 and a wire harness. The battery post terminal 4 is formed by performing a bending process or the like on a plate member made of an appropriate conductive metal material.

  As shown in FIG. 2, a part of the battery post terminal 4 (specifically, a tightening portion 42 described later) is disposed between the holder member 5 and the base member 6. From this state, the battery post terminal assembly 3 can be fixed to the battery post 2 by attaching the grip 41 provided to the battery post terminal 4 to the battery post 2 and tightening the tightening screw structure including the nut 7 and the like. It is configured. Details of the tightening screw structure will be described later.

  Next, each component provided in the battery post terminal assembly 3 will be described with reference to FIG.

  The battery post terminal 4 includes a grip portion 41 and two tightening portions 42.

  As shown in FIG. 3, the grip portion 41 is formed in an annular shape (in other words, an arc shape) with a part cut off, and a truncated cone-shaped insertion space 44 is formed inside thereof. A battery post 2 (FIG. 1) formed in a truncated cone shape can be inserted into the insertion space 44. In the following description, the central axis of the insertion space 44 formed in a truncated cone shape may be referred to as an insertion shaft 44A.

  As shown in FIG. 3, a plurality of grooves 44 v formed in an elongated rectangular shape are formed on the inner wall of the grip portion 41. The grooves 44v are arranged side by side at regular intervals in the circumferential direction. Each groove 44v is oriented so as to be substantially along the insertion shaft 44A. The battery post 2 can be strongly held by the uneven shape inside the holding part 41 generated by the groove 44v.

  The fastening portions 42 are arranged in a pair so as to extend from both ends of the arc-shaped gripping portion 41 and are formed integrally with the gripping portion 41. A space is formed between the two tightening portions 42, and the gripping portion 41 is deformed so that the diameter of the insertion space 44 is reduced by moving the tightening portions 42 closer to each other. Thereby, the battery post 2 can be clamped and held.

  Each tightening portion 42 includes two first inclined portions 45 and 47 and one second inclined portion 46. The second inclined portion 46 is disposed between the first inclined portion 45 on the side close to the grip portion 41 and the first inclined portion 47 on the side far from the grip portion 41. The first inclined portions 45 and 47 and the second inclined portion 46 are all formed in a flat plate shape and are formed integrally with the tightening portion 42. The first inclined portions 45 and 47 and the second inclined portion 46 included in the pair of tightening portions 42 are arranged so as to be symmetrical to each other. Moreover, it is comprised so that the screw part 61 with which the base member 6 is provided can be inserted between the 2nd inclination parts 46 which a pair of fastening part 42 has.

  The first inclined portion 45 on the side close to the grip portion 41 is disposed so as to be connected to the end portion of the grip portion 41. The first inclined portion 45 has a first inclined surface 45f that is inclined to one side with respect to the direction of the axis of the screw portion 61 (screw shaft 61A). In the present embodiment, the intervals between the first inclined surfaces 45f of the first inclined portions 45 located on the side closer to the gripping portion 41 in the respective tightening portions 42 decrease as the distance from the base side to the front end side of the battery post 2 decreases. It is arranged to let you.

  The second inclined portion 46 is disposed on the opposite side of the grip portion 41 with the first inclined portion 45 interposed therebetween. The second inclined portion 46 has a second inclined surface 46f that is inclined with substantially the same inclination angle as the first inclined surface 45f with respect to the screw shaft 61A. Accordingly, the second inclined surfaces 46 f of the second inclined portion 46 in each tightening portion 42 are arranged so that the interval increases as the distance from the base side to the front end side of the battery post 2 is approached.

  The first inclined portion 47 on the side far from the grip portion 41 is disposed on the opposite side of the first inclined portion 45 with the second inclined portion 46 interposed therebetween. The first inclined portion 47 has a first inclined surface 47f that is inclined at substantially the same inclination angle in the same direction as the first inclined surface 45f with respect to the screw shaft 61A. Accordingly, the first inclined surfaces 47f of the first inclined portions 47 located on the side farther from the gripping portion 41 in the respective tightening portions 42 are configured such that the interval decreases as the distance from the base side to the front end side of the battery post 2 decreases. Has been placed.

  The tip portion 48 is formed so as to be continuous with the first inclined portion 47 on the side far from the grip portion 41 in one of the two tightening portions 42. The distal end portion bends substantially perpendicularly from the distal end portion of the tightening portion 42 and extends toward the distal end of the other tightening portion 42 so as to close the space formed between the two tightening portions 42. Is arranged.

  The holder member 5 is disposed on one side of the tightening portion 42. The holder member 5 includes a flat plate portion 51 and four leg portions (first protrusions) 52.

  The flat plate portion 51 is formed as a flat plate-like portion, and is arranged so that the thickness direction thereof is parallel to the screw shaft 61A. The flat plate portion 51 is formed in an elongated rectangular shape, and the longitudinal direction thereof coincides with the direction in which the pair of fastening portions 42 are arranged. In addition, a penetrating circular hole 53 into which a screw part 61 included in the base member 6 can be inserted is formed at the center of the flat plate part 51.

  The leg portions 52 are arranged so as to protrude perpendicularly to the flat plate portion 51 from the four corners of the flat plate portion 51 (in a direction approaching the pedestal portion 62 included in the base member 6), and are integrally formed with the flat plate portion 51. ing. Each of these leg portions 52 is formed as a flat projection. Two leg portions 52 are arranged on one side in the longitudinal direction of the flat plate portion 51 and two on the other side, respectively, and the respective leg portions 52 face each other in the longitudinal direction of the flat plate portion 51 (in other words, tightening). A leg taper surface (first taper surface) 52f is formed on the surface facing the attachment portion 42).

  The leg taper surface 52f is configured to have an inclination corresponding to the first inclined surfaces 45f and 47f formed in the tightening portion 42. Specifically, the leg taper surface 52f is inclined with respect to the direction of the screw shaft 61A, and the inclination direction is the same as the inclination direction of the first inclined surfaces 45f and 47f, Their sizes are almost equal. Therefore, the leg taper surface 52f is arranged so that the distance from the leg taper surface 52f facing each other in the longitudinal direction of the flat plate portion 51 is decreased as the distance from the base side to the tip side of the battery post 2 is approached.

  Between the two leg portions 52 arranged on one side in the longitudinal direction of the flat plate portion 51, a second inclined portion 46 included in the one side tightening portion 42, a side wall portion 63 provided on the one side provided in the base member 6, and , Can be plugged in. Similarly, between the two leg parts 52 arrange | positioned at the longitudinal direction other side of the flat plate part 51, the 2nd inclination part 46 which the other side clamp | tightening part 42 has, and the side wall of the other side with which the base member 6 is provided. Part 63 can be inserted.

  The base member 6 is disposed on the opposite side of the holder member 5 with the tightening portion 42 interposed therebetween. The base member 6 includes a screw portion 61, a pedestal portion 62, and two side wall portions (second protrusions) 63.

  The screw part 61 is formed in an elongated round bar shape, and is arranged so that its axis (screw axis 61A) is parallel to the insertion axis 44A. The screw portion 61 can be inserted into a circular hole 53 formed in the flat plate portion 51. The screw portion 61 is formed with a male screw and can be screwed to the nut 7.

  The pedestal portion 62 is formed as a flat plate-like portion, and is arranged so that the thickness direction thereof is parallel to the axis of the screw portion 61. The pedestal portion 62 is formed in an elongated rectangular shape, and the longitudinal direction thereof coincides with the direction in which the pair of fastening portions 42 are arranged. One end of the screw portion 61 is fixed to the center of the pedestal portion 62.

  The side wall parts 63 are arranged in a pair so as to protrude in parallel with the screw part 61 from both longitudinal ends of the pedestal part 62 (in a direction approaching the flat plate part 51 included in the holder member 5). However, the length from which the side wall part 63 protrudes is shorter than the length from which the screw part 61 protrudes. A side wall taper surface (second taper surface) 63f is formed on a surface where the pair of side wall portions 63 face each other across the screw portion 61 (in other words, a surface facing the tightening portion 42 side).

  The side wall tapered surface 63f is configured to have an inclination corresponding to the second inclined surface 46f formed in the tightening portion 42. Specifically, the side wall tapered surface 63f is inclined with respect to the direction of the screw shaft 61A, and the direction of the inclination is the same as the direction of the inclination of the second inclined surface 46f. It is almost equal. Accordingly, the side wall taper surface 63f is disposed so that the distance from the side wall taper surface 63f facing each other in the longitudinal direction of the pedestal portion 62 increases as the distance from the base side to the front end side of the battery post 2 increases.

  The nut 7 includes a hexagonal portion 71 and an insertion portion 73.

  The hexagonal portion 71 is configured in a substantially regular hexagonal prism shape, and can be rotated by applying a force with an appropriate tool. A penetrating shaft hole 74 is formed at the center of the hexagonal portion 71, and a female screw is formed in the shaft hole 74. Therefore, the screw portion 61 of the base member 6 can be screwed to the shaft hole 74.

  The insertion portion 73 is a thin cylindrical portion integrally formed on one side of the hexagonal portion 71 in the axial direction, and is configured to be inserted into the circular hole 53 of the holder member 5.

  Next, the assembly process of the battery post terminal assembly 3 will be described with reference to FIGS. FIG. 3 is an exploded perspective view of the battery post terminal assembly 3. 4 is a cross-sectional view taken along the line AA in FIG. 3, showing a state where the nut 7 is assembled to the holder member 5. FIG. 5 is a perspective view showing a state of the battery post terminal assembly 3 before being tightened by the tightening screw structure. FIG. 6 is a schematic diagram viewed in the direction B of FIG. 5 for explaining the tightening force of the battery post terminal 4 generated by tightening by the tightening screw structure.

  As shown in FIG. 3, the assembly operator puts the screw portion 61 of the base member 6 between the pair of tightening portions 42 of the battery post terminal 4 with the screw shaft 61 </ b> A and the insertion shaft 44 </ b> A in parallel. Insert (from the base side of the battery post 2), and further pass through the circular hole 53 of the holder member 5, and attach the nut 7 to the tip. Thereby, the holder member 5 and the base member 6 are mutually connected by the fastening screw structure. In the present embodiment, since the screw shaft 61A is arranged in parallel with the center axis 2A of the battery post 2 (in other words, the insertion shaft 44A), a compact arrangement around the battery post 2 can be realized. The operation of rotating the nut 7 is also easy.

  FIG. 5 shows a state in which the nut 7 is rotated to some extent in the tightening direction. In the battery post terminal assembly 3 in this state, the leg taper surface 52f of the holder member 5 makes light contact with the first inclined surfaces 45f and 47f. In addition, the side wall tapered surface 63f of the base member 6 is in light contact with the second inclined surface 46f.

  In this state, the operator attaches the battery post terminal assembly 3 to the battery post 2 so as to insert the battery post 2 into the insertion space 44 of the gripper 41, and further rotates the nut 7 thereon. tighten. Then, as indicated by black arrows in FIG. 6, an axial force in a direction approaching the holder member 5 and the base member 6 acts. As a result, the clamping force F1 acts in the direction of narrowing the distance between the pair of tightening portions 42 from the leg taper surface 52f to the first inclined surfaces 45f and 47f. In addition, the clamping force F2 acts in a direction in which the distance between the pair of tightening portions 42 is reduced from the side wall tapered surface 63f to the second inclined surface 46f.

  As described above, in the battery post terminal assembly 3, the inclined surfaces (the first inclined surfaces 45f and 47f and the second inclined surface 46f) having different directions generate the clamping forces F1 and F2 in the same direction, thereby gripping the battery post terminal assembly 3. The battery post 2 is gripped by tightening the portion 41. Accordingly, since the battery post 2 can be tightened by applying force to the tightening portion 42 while distributing the force between the two inclined surfaces, the holder member 5 and the base member 6 locally bite into the tightening portion 42 and are durable. It can be prevented that it is difficult to remove even if the nuts 7 are loosened due to the strong deterioration of the members or the members 7 bite each other. Further, since the two inclined surfaces having opposite inclination directions are involved in the generation of the clamping forces F1 and F2, it is difficult for the force to be biased, and the battery post 2 can be stably held.

  In FIG. 6, the clamping force F1 is indicated by only two arrows. However, since the leg taper surfaces 52f are actually provided, the clamping force F1 is generated at four locations. That is, the first inclined surfaces 45f and 47f that generate the clamping force F1 together with the leg tapered surface 52f are arranged so as to sandwich the second inclined surface 46f, so that the balance of the force applied to the tightening portion 42 is balanced. It can be ensured satisfactorily.

  In this embodiment, the inclination angle of the leg taper surface 52f with respect to the screw shaft 61A and the inclination angle of the side wall portion taper surface 63f with respect to the screw shaft 61A are opposite to the screw shaft 61A and are substantially the same angle. It is formed to become. By defining the inclination angle symmetrically in this way, the clamping forces F1 and F2 can be easily generated from the two inclined surfaces, and more stable gripping can be realized.

  As described above, the battery post terminal assembly 3 of the present embodiment includes the battery post terminal 4, the holder member 5, and the base member 6. The battery post terminal 4 includes a gripping portion 41 and a tightening portion 42. The grip portion 41 can grip the battery post 2 on the inside. The tightening portions 42 are arranged in pairs so as to extend from the end portion of the grip portion 41. The holder member 5 is disposed on one side of the tightening portion 42. The base member 6 is disposed on the opposite side of the holder member 5 with the tightening portion 42 interposed therebetween. The holder member 5 and the base member 6 are connected to each other via a tightening screw structure. The holder member 5 is formed with a leg taper surface 52f that is inclined with respect to the direction of the screw shaft 61A of the tightening screw structure. The base member 6 is formed with a side wall taper surface 63f that is inclined in a direction opposite to the leg taper surface 52f with respect to the direction of the screw shaft 61A of the tightening screw structure. In each of the tightening portions 42, first inclined surfaces 45f, 47f and a second inclined surface 46f are formed. The first inclined surfaces 45f and 47f are formed in a direction corresponding to the leg taper surface 52f and can contact the leg taper surface 52f. The second inclined surface 46f is formed in a direction corresponding to the side wall tapered surface 63f and can contact the side wall tapered surface 63f, and is inclined in the opposite direction to the first inclined surfaces 45f and 47f.

  Thereby, the force is applied to the tightening portion 42 while the force is distributed between the two inclined surfaces of the leg tapered surface 52f and the first inclined surfaces 45f and 47f and the side wall tapered surface 63f and the second inclined surface 46f. In addition, since the battery post 2 can be tightened, it is possible to prevent the holder member 5 and the base member 6 from locally biting into the tightening portion 42 and lowering the durability.

  Further, in the battery post terminal assembly 3 of the present embodiment, in each tightening portion 42, the first inclined surface 45f is disposed closer to the grip portion 41 than the second inclined surface 46f, and the first inclined surface 47f is arrange | positioned in the side far from the 2nd inclined surface 46f seeing from the holding part 41. As shown in FIG.

  Thereby, while being able to disperse | distribute force more and to be able to apply without biasing the force with respect to the fastening part 42, stable fastening is realizable.

  Further, in the battery post terminal assembly 3 of the present embodiment, the holder member 5 is formed with a pair of leg portions 52 that protrude in a direction approaching the base member 6. The base member 6 is formed with a pair of side wall portions 63 protruding in a direction approaching the holder member 5. A leg taper surface 52f is arranged on the surface of the leg 52 facing the tightening portion 42 side. A side wall taper surface 63f is disposed on a surface of the side wall portion 63 facing the tightening portion 42 side.

  Thereby, it can clamp | tighten with a simple structure, distributing force.

  In the battery post terminal assembly 3 of the present embodiment, the leg taper surface 52f is inclined to one side with respect to the direction of the screw shaft 61A of the tightening screw structure. The side wall taper surface 63f is inclined in the direction opposite to the leg taper surface 52f at substantially the same angle as the inclination angle of the leg taper surface 52f with respect to the direction of the screw shaft 61A of the tightening screw structure.

  As a result, the tightening force can be applied evenly without causing any bias.

  Further, in the battery post terminal assembly 3 of the present embodiment, the screw shaft 61 </ b> A having a tightening screw structure is arranged in parallel with the central shaft 2 </ b> A of the battery post 2.

  As a result, a compact arrangement around the battery post 2 can be realized, and the work of tightening or loosening the tightening screw structure can be simplified.

  Further, in the battery post terminal assembly 3 of the present embodiment, irregularities are formed on the inner surface of the grip portion 41.

  Thereby, the battery post 2 can be gripped strongly.

  Next, a modification of the above embodiment will be described. FIG. 7 is a cross-sectional view showing a state in which the nut 7 is assembled to the holder member 5 in an inseparable manner in the battery post terminal assembly according to the modification.

  In the battery post terminal assembly of this modification, in the step of assembling the nut 7 to the holder member 5, the shaft hole 74 is inserted into the circular hole 53 as shown in FIG. The pressing tool 10 is brought close to the shaft 74 </ b> A so that the center axis thereof coincides with the shaft 74 </ b> A, and the plug 73 is pressed. Since the diameter of the pressing tool 10 is larger than the inner diameter of the insertion portion 73, as shown in FIG. 7B, the portion protruding from the circular hole 53 of the insertion portion 73 to the inside of the holder member 5 is pressed. When the tool 10 is pressed, the portion is bent outward in the radial direction of the circular hole 53, and a bent portion 73a is formed. Since the nut 7 can be attached so as not to be detached from the holder member 5 by this bending process, the work of assembling the battery post terminal assembly 3 is facilitated. Even when the bent portion 73a is formed, the nut 7 can freely rotate with respect to the holder member 5, so that the nut 7 can be tightened without any problem. Further, since the nut 7 and the holder member 5 are connected, even if the leg portion 52 of the holder member 5 bites into the first inclined portions 45 and 47 of the battery post terminal 4, When loosened, the holder member 5 is integrated with the nut 7 and detached from the battery post terminal 4, so that the tightening portion 42 can be loosened.

  The preferred embodiments and modifications of the present invention have been described above, but the above configuration can be modified as follows, for example.

  The inclination directions of the first inclined surfaces 45f and 47f and the second inclined surface 46f are not limited to those shown in FIG. In this case, instead of forming the circular hole 53 in the flat plate portion 51 of the holder member 5, a screw portion is provided so as to protrude, and instead of providing the screw portion 61 in the pedestal portion 62 of the base member 6, a circular hole is formed. What is necessary is just to arrange | position so that 5 may become a lower side and the base member 6 may become an upper side.

  The inclination of the first inclined surfaces 45f and 47f can be made tighter or looser than the inclination of the second inclined surface 46f.

  In the above embodiment, the first inclined surfaces 45f, 47f, the second inclined surface 46f, the leg taper surface 52f, and the side wall taper surface 63f are all flat inclined surfaces, but are changed to curved surfaces. You can also

  In the above-described embodiment, four leg portions 52 are provided, but the number of leg portions 52 is not limited thereto, and may be two. In this case, if the two leg portions 52 that are in contact with the first inclined surface 47f far from the grip portion 41 are omitted, a clamping force can be efficiently applied to the side close to the grip portion 41. preferable.

  The grooves 44v provided in the grip portion 41 are formed in a long and narrow rectangular shape at regular intervals. However, if the configuration can prevent the battery post terminals 4 from shifting, the interval and shape of the grooves 44v should be changed as appropriate. Can do. In addition, unevenness may be realized by forming a large number of circular recesses instead of grooves.

  The shaft of the screw portion 61 (screw shaft 61A) may be disposed so as not to be parallel to the insertion shaft 44A but to be appropriately inclined. In this case, the axial force acting in the direction in which the holder member 5 and the base member 6 are brought closer to each other by tightening the nut 7 is favorably applied to the clamping forces F1 and F2 acting in the direction of narrowing the distance between the pair of fastening portions 42. It is preferable to appropriately change the directions of the first inclined surfaces 45f and 47f and the second inclined surface 46f so that they can be converted.

  A protrusion or the like may be formed on the battery post terminal 4 to prevent the base member 6 from being detached from the battery post terminal 4 even when the nut 7 is removed from the screw portion 61 of the base member 6. In this case, assembly workability can be improved.
