Vertical mount battery fuser terminal

Abstract

A vertical mounted battery terminal mounting assembly includes a battery having a terminal post. A post attachment structure including a contact portion shaped to engage the terminal post of the battery is provided. The post attachment structure includes a wedge translation portion having an angled slide surface. An internal wedge is positioned within the post attachment structure. The internal wedge includes an angled wall and terminal contacts. A core bolt is rotationally fixed and extends through the post attachment structure and the internal wedge. A nut is threaded on the core bolt and contacts an upper edge of the internal wedge wherein the angled wall of the internal wedge engages the angled slide surface of the post attachment structure. Rotation of the nut imparts a downward force on the internal wedge wherein contact of the angled wall and the slide surface evenly translates the downward force to a horizontal force wherein the terminal contacts and the contact portion engage the battery terminal post.

DETAILED DESCRIPTION OF THE EMBODIMENTS

(13) Referring to FIGS. 1-12 there is detailed a vertical mounted battery terminal mounting assembly 20 for attaching to a battery 22. In one aspect, the battery 22 includes a terminal post 24.

(14) Referring to FIG. 1, a post attachment structure 26 includes a contact portion 28 formed with a wedge translation portion 30. In one aspect, the contact portion 28 is shaped to surround the terminal post 24 of the battery 22. The wedge translation portion 30 includes opposing walls 32 that are joined by an angled slide surface 34. In one aspect, the contact portion 28 may be monolithically formed with the wedge translation portion 30.

(15) In one aspect, the contact portion 28 may include a ring shaped wall 36 having an open top and bottom 38, 40. The ring shaped wall 36 may include a neck 42 that transitions to the wedge translation portion 30. The neck 42 may include cut out slots 44 formed therein that accommodate terminal contacts 46, as will be discussed in more detail below.

(16) The mounting assembly 20 also includes an internal wedge 48 that is positioned within the post attachment structure 26. The internal wedge 48 includes an u-shaped body 50 having opposing side walls 52 coupled by an angled wall 54. The opposing side walls 52 include terminal contacts 46 extending therefrom. The mounting assembly 20 also includes a core bolt 56 that is rotationally fixed and extends through the post attachment structure 26 and into a cavity 58 defined by the separated opposing side walls 52 of the internal wedge 48. In one aspect, the core bolt 56 may be rotationally fixed by securing a head 60 of the core bolt 56 such that it cannot spin or rotate, as will be discussed in more detail below.

(17) A nut 62 is threaded on the core bolt 56 and may contact an upper edge 64 of the internal wedge 48. A washer 66 may be positioned about the core bolt 56 with the nut 62 contacting the washer 66 which in turn contacts the upper edge 64 of the internal wedge 48. The outer surface of the angled wall 54 of the internal wedge 48 engages the angled slide surface 34 of the post attachment structure 26 such that rotation of the nut 62 imparts a downward force 70 on the internal wedge 48 wherein contact of the angled wall 54 and the slide surface 34 evenly translates the downward force 70 to a horizontal force 72 moving the terminal contacts 46 into engagement with the terminal post 24.

(18) In one aspect, the angle of the angled wall 54 of the internal wedge 48 and the angled slide surface 34 may be from 15 to 25 degrees as measured from a vertical axis. The angle of the components when in the unengaged state may allow for a vertical translation of the nut resulting in a horizontal translation of the contacts such that they securely and evenly engage the terminal post 24.

(19) Referring to FIG. 5, there is shown the translation of the forces including the downward force 70 as well as the opposing upward force 71 associated with the core bolt 56 and nut 62. Additionally, there is shown the sliding forces 74, 76 applied between the internal wedge 48 and post attachment structure 26. Further, as depicted, the horizontal force 72 is evenly applied to the terminal contacts 46 for securely engaging the mounting assembly 20 about a terminal post 24 of a battery 22.

(20) Again referring to FIGS. 1 and 2, the wedge translation portion 30 includes an open top and a bottom surface 78 having a slot 80 formed therein that receives the core bolt 56. The terminal contacts 46 may include a curved body 82 that extends outward relative to the opposing side walls 52 of the internal wedge 48. In one aspect, the curved bodies 82 define a variable engagement diameter with the terminal post 24. Such an engagement diameter may accommodate various post sizes of batteries such that when in the unengaged position the internal wedge allows easy assembly of the post attachment structure about the battery terminal post and also may allow engagement of the terminal contacts with various terminal post sizes.

(21) Referring to FIGS. 6-8, there is depicted an additional battery electrical component 84 positioned on the battery 22. In one aspect, the additional battery electrical component 84 may be a battery fuser terminal to allow additional wire harnesses to be coupled to the battery from a single terminal mounting assembly 20. In one aspect, the core bolt 56 may be rotationally fixed by the additional battery electrical component 84. Referring to FIG. 7, there is shown one version of an additional electrical component 84 wherein the core bolt 56 includes a head 60 having a threaded shaft 86 that extends therefrom for engaging the nut 62. The battery electrical component 84 includes a cavity with a through hole 88 formed therein with the threaded shaft 86 extending through the cavity with a through hole 88 and the head 60 of the core bolt 56 is positioned in the cavity with a through hole 88 and is rotatively restrained or fixed preventing rotation of the core bolt 56.

(22) Referring to FIG. 8, there is shown an additional battery component where the core bolt 56 includes a head 60 having a threaded shaft 86 that extends therefrom for engaging the nut 62. In the depicted embodiment, the battery electrical component 84 is joined to the head 60 of the core bolt 56 again preventing rotation or restraining the core bolt rotatively. Various methods and structures may be used to fix the head 60 of the core bolt 56 onto the additional electrical component 84. For example, the core bolt 56 may be press fit, welded or molded with the additional component 84 to permanently fix the core bolt 56 rotatively.

(23) Referring to FIGS. 9-12, operation and attachment of the mounting assembly 20 will be described. Referring to FIGS. 9 and 10, the internal wedge 48 is positioned within the post attachment structure 26 with the core bolt 56 passing through the post attachment structure 26 and the internal wedge 48. The nut 62 is threaded on the core bolt 56 and contacts an upper edge 64 of the internal wedge 48. In this state the internal wedge 48 is in an unengaged position such that the post attachment structure 26 may be fitted about the terminal post 24 of the battery 22 and the terminal contacts 46 are not in engagement with the terminal post 24.

(24) Referring to FIGS. 11 and 12, the nut 62 may be tightened on the core bolt 56 such that a downward force is applied to the internal wedge 48 where contact of the angled wall 54 and the slide surface 34 evenly translates the downward force 70 to a horizontal force 72 moving the terminal contacts 46 toward an engagement with the terminal post 24. Continued rotation of the nut 62 applies a downward force on the internal wedge 48 with continued movement horizontally of the terminal contacts 46 until it is in an engaged position with the terminal post 24. In the engaged position, the terminal contacts 46 engage the terminal post 24 on a portion of a terminal post and the contact portion 28 of the post attachment structure 26 surrounds an additional portion of the terminal post 24. In the engaged position, an even force is applied to the terminal contacts 46 securely retaining the mounting assembly 20 with the terminal post 24.
