  However, the conventional battery terminal is held against the battery post at only one point that is fastened to the battery post. For this reason, when the mass of the parts assembled to the battery terminal increases, the load applied to the battery post may increase.

  The present invention has been made in view of the above, and an object of the present invention is to provide a battery terminal resin part and a battery terminal unit that can reduce a load applied to the battery post in a state where the battery terminal is assembled to the battery post. .

In order to solve the above problems, a resin component for a battery terminal according to the present invention is a resin component for a battery terminal that is assembled to a battery terminal having a connection portion connected to an electric wire on a main body side on which a battery is mounted, A bottom cover that is interposed between the battery terminal and the opposing surface of the battery post in a state in which the battery terminal is attached to a battery post that is erected on the battery, and supports the battery terminal on the opposing surface; the formed on bottom cover is disposed in a gap between the connecting portion and the battery of the surface of the battery terminals, characterized in that it comprises a support member for supporting the connecting portion to the surface of the battery .

  In the battery terminal resin component described above, it is preferable that the support member is a vibration absorbing material.

  Similarly, in order to solve the above-described problems, a battery terminal unit according to the present invention includes the battery terminal resin component and a battery terminal to which the battery terminal resin component is assembled.

  Since the resin part for battery terminals and the battery terminal unit according to the present invention can support the connection part by the support member, the load applied to the connection part is prevented from being transmitted to the battery post via the battery terminal. As a result, it is possible to reduce the load applied to the battery post in a state where the battery terminal is assembled to the battery post.

In the following description, the extending direction of the axis C illustrated in the vertical direction in FIG. Further, the direction around the axis C is represented as “circumferential direction”.

  The battery terminal unit 10 according to the present embodiment is attached to a battery post 3 erected on a battery 4 mounted on a vehicle or the like, as shown in FIGS. Hereinafter, it is also referred to as “resin component 1”) and a battery terminal 2. The resin component 1 is assembled to the battery terminal 2. The battery terminal 2 is a component for electrically connecting the battery 4 and an electric wire (not shown) on the main body side of a vehicle or the like on which the battery 4 is mounted by being attached to the battery post 3. The battery terminal unit 10 is attached to the battery post 3 in a state where the resin component 1 is integrally assembled to the battery terminal 2. The “axial direction” described above is the axial direction of the battery post 3 and is the direction in which the battery post 3 is erected on the battery 4. In general, the battery post 3 has a substantially cylindrical shape, and further tapers so that the diameter of the outer peripheral side surface 33 becomes smaller as it proceeds from the base 31 side, which is a connection portion with the battery 4, to the tip end 32 side along the axial direction. Is attached.

  As shown in FIG. 1, the battery terminal 2 includes a pair of annular portions 21 a and 21 b that are arranged so as to overlap in the axial direction. When the battery terminal 2 is attached to the battery post 3, the pair of annular portions 21 a and 21 b are positioned so that one annular portion 21 a is positioned on the tip 32 side of the battery post 3 and the other annular portion 21 b is on the base 31 side. It is arranged to be located. A post insertion hole 22 for inserting the battery post 3 into the inside is formed in the annular portions 21a and 21b. The annular portions 21a and 21b are opened by a tightening gap 23 obtained by dividing one place in the circumferential direction of the post insertion hole 22, and a pair of connecting portions 24a and 24b opposed in the circumferential direction across the tightening gap 23. It is connected. Further, the joining plates 25a and 25b are connected to the annular portions 21a and 21b so as to overlap each other in the axial direction at a position opposite to the circumferential direction of the connecting portions 24a and 24b.

  When the battery terminal 2 is attached to the battery post 3, the joining plates 25 a and 25 b are located on the base 31 side of the battery post 3 and the other joining plate 25 b is located on the distal end portion 32 side. It is arranged as follows. A terminal fixing bolt 26 is erected on the joining plate 25a on the base 31 side. The terminal fixing bolt 26 is installed upright in a direction substantially parallel to the axial direction through the other joining plate 25b. An electric wire (not shown) on the main body side is connected and fixed to the terminal fixing bolt 26. In the present embodiment, these joining plates 25a and 25b and the terminal fixing bolts 26 function as the “connecting portion 41 that connects to the electric wire on the main body side on which the battery 4 is mounted”.

  A tightening bolt 27 crossing the tightening gap 23 is passed through the pair of connecting portions 24a and 24b. The tightening bolt 27 installed through the connecting portions 24a and 24b can tighten the connecting portions 24a and 24b in the approaching direction in cooperation with the nut 28 fitted at the tip thereof. As a result, the post insertion holes 22 of the annular portions 21a and 21b are reduced in diameter.

  The post insertion hole 22 is formed with a hook-shaped contact portion 29 in which the hole edge portion is bent in an upright state (so-called protruding). The contact portion 29 is formed by bending the battery post 3 toward the base portion 31 (downward in FIG. 1) in each of the pair of annular portions 21a and 21b. The contact portion 29 has a tapered shape that matches the taper of the battery post 3 and has an inner peripheral surface. Therefore, in the battery terminal 2 in which the battery post 3 is inserted into the post insertion hole 22, the contact portion 29 is brought into close contact with the outer peripheral side surface 33 of the battery post 3 by tightening the nut 28 and bringing the tightening gap 23 closer. Can be attached.

  Here, as shown in FIG. 1, the base 31 of the battery post 3 is generally larger in diameter than the outer peripheral side surface 33 and has a shape projecting radially outward, and therefore has an annular shape along the periphery of the outer peripheral side surface 33. It has a facing surface 31a. The facing surface 31 a is disposed substantially parallel to the end surface of the tip end portion 32. In the battery terminal 2, the post insertion hole 22 is inserted into the battery post 3, and the bottom surface (more specifically, the bottom surface of the resin component assembled to the battery terminal 2) abuts the facing surface 31 a of the base 31 of the battery post 3. In this state, it is attached to the battery post 3 (see FIG. 4).

  The resin component 1 is integrally assembled to such a battery terminal 2. The resin component 1 is a member interposed between the battery terminal 2 and the battery 4 as an anticorrosion cover that gives the battery terminal 2 an anticorrosion function. For this reason, the resin component 1 is molded using a synthetic resin material in order to provide corrosion resistance to the battery liquid (to provide an anticorrosion function).

  As shown in FIG. 1, the resin component 1 includes a bottom cover 11, a lid portion 12, a hinge 13, a lock portion 14, and a support member 15. As shown in FIG. 2, the resin component 1 is assembled integrally with the battery terminal 2 by sandwiching the battery terminal 2 between the bottom cover 11 and the lid portion 12 and maintaining the sandwiched state by the lock portion 14. It is configured as follows. In the resin component 1, the bottom cover 11, the lid portion 12, the hinge 13, and the lock portion 14 are integrally formed of the above synthetic resin material. The support member 15 is formed of a vibration absorbing material such as rubber or silicon.

  As shown in FIG. 1, the bottom cover 11 is interposed between the battery terminal 2 and the facing surface 31a of the battery post 3, and covers the bottom surface of the battery terminal 2 (the surface on the annular portion 21b and the joining plate 25a side). It is a plate-like member. An insertion hole 17 for the battery post 3 is formed through the bottom cover 11. A temporary lock portion 16 is provided on the bottom cover 11 on the surface facing the battery terminal 2. The temporary lock portion 16 is a member for temporarily fixing the battery terminal 2 to the bottom surface cover 11, and in this embodiment, the configuration of the locking protrusion is illustrated. The temporary lock portion 16 can be locked to the openings 42 on the side surfaces of the annular portions 21a and 21b of the battery terminal 2 in a state where the battery terminal 2 is assembled to the bottom cover 11, and the gap between the joining plates 25a and 25b. Can be locked to.

  As shown in FIG. 2, the lid 12 is a plate-like member that covers the battery terminal 2 from the side opposite to the bottom cover 11 in the axial direction. In the present embodiment, the lid portion 12 has a substantially strip shape and is illustrated as a substantially bridge-shaped plate member. The lid portion 12 is disposed so as to contact the surface opposite to the bottom surface of the battery terminal 2 (the surface on the annular portion 21a and the joining plate 25b side). An insertion hole escape portion 12 a that allows the battery terminal 2 to escape from the post insertion hole 22 is formed in the center portion of the lid portion 12. The lid portion 12 extends in a direction parallel to the axial direction of the fastening bolt 27 of the battery terminal 2.

  As shown in FIG. 1, the hinge 13 is a part that connects the bottom cover 11 and the lid 12. The hinge 13 is formed thinner than the other parts of the resin component 1 and can be freely deformed. For this reason, in the resin component 1, the inclination angle of the lid portion 12 with respect to the bottom surface cover 11 can be changed around the connection position with the hinge 13.

  The lock portion 14 is a portion that fixes the lid portion 12 to the bottom surface cover 11. The lock portion 14 is formed on both the lid portion 12 and the bottom cover 11. The lock part 14 is comprised by the latching protrusion and the latching frame part hooked on this latching protrusion, for example.

  The support member 15 is formed on the bottom surface of the bottom cover 11 that faces the facing surface 31 a of the battery post 3 when attached to the battery post 3. As shown in FIGS. 3 and 4, the support member 15 is at least between the connection portion 41 of the battery terminal 2 and the surface 4 a of the battery 4 in a state where the resin component 1 and the battery terminal 2 are assembled to the battery post 3. It arrange | positions in an area | region and is comprised so that the connection part 41 can be supported. In other words, the support member 15 is a gap between the connection portion 41 of the battery terminal 2 and the surface 4a of the battery 4, and at least overlaps with the terminal fixing bolt 26 of the connection portion 41 when viewed from the axial direction. Preferably, it arrange | positions in the area | region which overlaps with the connection part 41 whole. The support member 15 is formed of a vibration absorbing material such as rubber or silicon as described above. The support member 15 is fixed to the bottom cover 11 by a method such as being integrally formed with other portions of the resin component 1 or being fixed with an adhesive material or the like.

  Next, a procedure for assembling the resin component 1 to the battery terminal 2 and attaching the battery terminal 2 to which the resin component 1 is assembled, that is, the battery terminal unit 10 to the battery post 3 will be described.

  First, the battery terminal 2 is assembled on the bottom cover 11 of the resin component 1, and the battery terminal 2 is temporarily fixed on the bottom cover 11 by the temporary lock portion 16. Next, the lid 12 is pushed down to a position covering the battery terminal 2 from the side opposite to the bottom cover 11 in the axial direction. Then, the lock portion 14 is fitted and the lid portion 12 is fixed to the bottom surface cover 11. Thereby, as shown in FIG. 2, the resin component 1 and the battery terminal 2 are finally fitted, the resin component 1 is assembled to the battery terminal 2, and the battery terminal unit 10 is integrally formed.

  Next, the battery post 3 is inserted into the battery terminal 2 to which the resin component 1 is assembled, that is, the post insertion hole 22 of the battery terminal unit 10, and the bottom surface of the bottom cover 11 of the resin component 1 is the battery post as shown in FIG. 3 is abutted against the facing surface 31a of the base 31 of the third. At this time, the support member 15 provided on the bottom surface of the bottom surface cover 11 of the resin component 1 is also in contact with the surface 4a of the battery 4 on which the battery post 3 is installed, as shown in FIGS. In this state, the battery terminal unit 10 is attached to the battery post 3 by tightening the tightening bolt 27 and the nut 28 of the battery terminal 2. Therefore, the battery terminal unit 10 is supported on the opposite surface 31a of the battery post 3 by the bottom cover 11 of the resin component 1 and also supported by the surface 4a of the battery 4 by the support member 15 of the resin component 1. It will be attached to the battery post 3 in a state of point support. The support member 15 is disposed between the connection portion 41 of the battery terminal 2 and the surface 4a of the battery 4 as described above. The connection portion 41 is connected to other devices in the vehicle body and thus receives a load from the outside in many cases. However, the support member 15 can support the connection portion 41 on the surface 4 a of the battery 4.

  Next, effects of the battery terminal resin part 1 and the battery terminal unit 10 according to the present embodiment will be described.

  The battery terminal unit 10 of this embodiment includes a battery terminal resin part 1 and a battery terminal 2. The battery terminal resin component 1 is assembled to the battery terminal 2 having a connection portion 41 connected to the electric wire on the main body side on which the battery 4 is mounted. The battery terminal resin component 1 is disposed in the gap between the connection portion 41 of the battery terminal 2 and the surface 4a of the battery 4 in a state where the battery terminal 2 is attached to the battery post 3 erected on the battery 4. A support member 15 that supports the connection portion 41 on the surface 4 a of the battery 4 is provided.

  As shown in FIG. 4, this configuration also increases the mass of the component on the main body side connected to the connection portion 41 and increases the load applied to the connection portion 41 due to the influence of vibration or the like. Since the connection portion 41 can be supported on the surface 4 a of the battery 4 by the member 15, it is possible to suppress the load applied to the connection portion 41 from being transmitted to the battery post 3 via the battery terminal 2. This makes it possible to reduce the bending moment that the battery post 3 receives. As a result, the battery terminal resin component 1 and the battery terminal unit 10 of the present embodiment are in a state where the battery terminal 2 is assembled to the battery post 3. The load on the battery post 3 can be reduced.

  Further, in the battery terminal resin part 1 and the battery terminal unit 10 of the present embodiment, since the support member 15 is a vibration absorber, the load applied to the connection portion 41 can be absorbed by the support member 15. Since the load transmitted from the battery terminal 2 to the battery post 3 can be further suppressed, the load applied to the battery post 3 can be further reduced.

  As mentioned above, although embodiment of this invention was described, the said embodiment was shown as an example and is not intending limiting the range of invention. The above embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. The above-described embodiments and modifications thereof are included in the invention described in the claims and the equivalents thereof, as long as they are included in the scope and gist of the invention.

  In the above-described embodiment, the configuration in which the support member 15 is a vibration absorbing material has been exemplified. However, the support member 15 may use other materials as long as it can support the connection portion 41. For example, the support member 15 may be integrally formed of a synthetic resin material in the same manner as the other elements of the battery terminal resin part 1.
