The present technology relates generally to a battery connector for connecting one or more electric leads to a battery terminal post.
The use of battery connectors to attach leads to a battery terminal is known. For example, battery connectors are found in cars, boats, caravans, trucks, tractors, trains, locomotives, trailers, campervans and other vehicles.
One disadvantage of such connectors is that they cannot be readily adjusted for different diameter battery terminals. Hence, typically, different-sized connectors are required for different battery post dimensions. Having such connectors of different sizes and configurations is costly and inefficient.
Further, having many different connector types requires the user to learn numerous securing methods during installation, which is time consuming.
In addition, it is useful to provide safety when dealing with live batteries. The risks of an injurious electrical failure, or an “arc up” as it is colloquially known in the field, is real. This poses a risk to the health of the user, along with a possible electrical burnout risk to other electrical components.
Battery terminal post connectors are largely slow to connect and release from the terminal post. They can also be insecure in their connection to the terminal post, which leads to arcing and power loss.
Also, attachment of an auxiliary lead can be difficult and slow, or the access can be un-ergonomic.
The present technology seeks to provide a connector that substantially ameliorates one or more of the abovementioned disadvantages.
Throughout this specification and the claims that follow, the phrase “automotive battery” is to be considered as encompassing many kinds of rechargeable battery for use in heavy applications such as for example automotive, marine, agricultural, trucking, mining and the like. The type of battery could include lead-acid, AGM, lithium-ion, gel, sealed, VRLA, SLA, deep cycle and the like. The batteries may be 12V, 24V, 48V, and like potentials, with capacities of 50-100+Ah, and/or 1000 CCA or similar specification.

A battery connector for a battery terminal having a terminal post, comprising: an inner clamp including:
To enable a clearer understanding, embodiments of the present technology will hereinafter be described with reference to the attached drawings, and in those drawings:
When assembled, the quick clamp actuator (1) is pivotally attached to the clamp body (2). This allows for ready securing of, and readily-releasable securing of, the connector (20) to a terminal post (not shown) of a battery (30) once the clamp (2) is placed upon the terminal post. Plastic hinges or other electrically inert hinges and the like are suitable for this purpose.
The quick clamp actuator (1) is in the form of a substantially insulating cover (81) and includes two cylindrical apertures (11a, 11b), one on either side of the insulating cover (81). These cylindrical apertures (11a, 11b) each accept two slightly smaller cylindrical bosses (11c, 11d) which form part of the clamp (2), and when the cylindrical apertures (11a, 11b) engage the cylindrical bosses (11c, 11d), they act as a pivot. This in turn allows the insulating cover (81) to move from a closed position covering the clamp body (2) to an open position, wherein the clamp (2) is exposed, and its grip on the terminal post is released as described below.
The connector (20) includes a terminal end (85) for connecting to the terminal post and a lead end (86) for connecting one or more leads (10) and (51). On the terminal end of the cover is snap female lock element (5b) designed to snap closed and lock the insulating cover (81) in the closed position over with the clamp (2) which has a correspondingly designed and closely fitted snap lock male section (5a).
Above the snap female lock element (5b) is an extended lip (6) to assist the user in gripping the insulating cover (81) when intending to open the insulating cover (81) and disengage the connector (20).
Referring now to
A lead-in (2f, 102f) is provided to allow a tolerance in the fitment of the sliding of the ramps past one another.
On an inner face of the insulating cover (81) and adjacent to the adjuster (3) is the adjustment arm (4) which is a ramp or a flange (4a). When screwed in or out, the adjustment screw (3a) will vary a closing diameter of an arcuate wall (2d) of the clamp (2) to enable the clamp (2) to be attached to a variety of different diameter battery terminal posts as described below. Different battery terminals have different diameter terminal posts, and therefore this feature allows the battery connector to be used with a variety of battery terminal posts of different sizes.
The adjustment arm (4) is used to bias against and engage with the adjustment leg (2a) of the clamp (2). The clamp (2) further comprises an aperture (2c) for receiving the battery terminal post. The biasing of the adjusting arm (4) against the adjustment leg (2a) reduces the diameter of the terminal post aperture (2c) as the insulating cover (1) is moved to the closed position over the clamp (2), hence tightly fitting the clamp (2) over the terminal post. The diameter of the terminal post aperture provided by the arcuate wall (2d) of the clamp (2) is set by varying the depth of the adjustment screw (3a), and as a result, the adjustment arm (4) has an inward movement from its original position in the insulating cover (1). This inward movement is the amount of deflection of the adjustment arm (4) from its natural rest position (See
Referring now to
On the underside of the end (2b) proximal to the input aperture (15) is a lead mounting zone (70) including a securing means (9) for securing the lead (10) to the battery connector.
As shown in
The securing means (9) can also include a threaded section (9c, 9d, 9e) for attaching other auxiliary smaller cables to power auxiliary devices such as extra driving lights on a vehicle.
Referring now to
The end proximal to the battery terminal post aperture (2c) includes the snap lock male section (5a) integrally formed as part of the inner clamp (2). The snap lock male section (5a) is shaped and designed to be closely fitted with the snap lock female section (5b) correspondingly located on the insulating cover (81) as discussed above. This forms a releasable lock, holding the insulating cover (81) and clamp body (2) in a locked and secure position when engaged.
The three widths shown in
The portion of the clamp body (2) forming the battery terminal post aperture (2c) is tapered to fit closely with and over the battery terminal post and is closed off or reduced in diameter as the battery connector is closed. The adjustment leg (2a) is bevelled and shaped to abut the adjustment arm (4) of the insulating cover (81) such that when the insulating cover (81) is lowered, the adjustment leg (2a) engages with the adjustment arm (4) and begins to close off the terminal post aperture (2c) in order to tighten about a battery post terminal.

In a further embodiment, a kit for connecting a lead to a battery terminal is also envisaged. The kit comprises a battery connector according to any one of the preceding claims; a lead affixed to the battery connector; and the lead at the opposite end having an electrical attachment means affixed thereto. The electrical attachment means is also a battery connector as herein described. However, the electrical attachment means can also include alligator clips, large O-rings or C-rings, and the like as understood in the art.
Further, another kit for connecting leads to a battery terminal is also envisaged. This kit comprises: at least two battery connectors as herein described, a lead connected to each of the two battery connectors and each lead having at the opposite end an electrical attachment means affixed thereto. Each of the electrical attachment means are also battery connectors as herein described. This kit provides a pair of “jumper leads” to connect, for example, two adjacent battery terminals together. The electrical attachment means including alligator clips, clamps, large O-rings or C-rings, and other electrical attachment means as understood by the skilled person for connecting to ancillary electrical devices.
One of the differences between the embodiments is that the adjustment arm (104) is not horizontal but vertical in disposition (when the cover is closed). The adjustment arm is a ramp (104a) or a flange which includes a broad surface to facilitate a strong clamping connection between the arm (104) and the leg (102) and therefore a strong clamp around the terminal post. The adjustment leg (102) is also a ramp to facilitate a strong connection between the arm (104) and the leg (102) and to facilitate a tight connection around the terminal post.
Also, the adjustment screw (103a) is a thumb screw to provide ready and toolless adjustability for the adjustment leg (104) to provide secure clamping for multiple diameter terminal posts.
Furthermore, instead of bosses (11c and 11d) and recesses (11a and 11b), the insulating cover (101) pivots about screws (111) when it moves between the release position shown in
In this embodiment there is also provided a port (199) in the side of the cover (101) to provide access for a screwdriver (not shown) for ready (tooled) release of the connector by gently prising up the cover (101) and thereby releasing the clamp (102).
Another difference between the embodiments is that the battery connector (120) in
The access closure (150) is configured to swing about pivots (160) to move between the closed position shown in
When in the open position, the access closure (150) allows access to the auxiliary lead (151) in the auxiliary lead mounting zone (170). In the auxiliary lead mounting zone (170) there is provided an auxiliary lead mounting screw (171) and a main lead mount (172). The main lead mount (172) is a main lead saddle clamp (173) and that saddle clamp (173) is held together by two saddle screws (174) to securely fasten the main lead to the clamp body (102).
Rather than, as in Embodiment One, a lip (6) extending directly from the cover (101), in Embodiment Two the extended lip (106) is disposed above a notch or recess (106a) to further assist the user in gripping the insulating cover (101) when intending to open the insulating cover (101) and disengage the connector (120). This helps to provide a stronger lip (106) and allows more force to be brought to bear on lifting the cover (101). A finger may enter the recess (106a) to provide toolless quick release.
In both embodiments it can be seen that the arcuate wall (2d, 102d) extends mostly around a periphery of a terminal post (if it were fitted around the terminal post) and the adjustment leg (2a, 102a) extends from one end of the arcuate wall. The arcuate wall (2d, 102d), then causes an aperture to open and close around the terminal post when the adjustment leg (2a, 102a) is pushed in by the clamp actuating cover (1, 101), and the size of the aperture is governed by the amount that the adjustment arm (4, 104) is adjusted by the thumb screw or other adjusting screw (3a, 103a).
There may also be provided ribs or teeth (not shown) on the inner face of the arcuate wall (2d, 102d).
The access cover (101) and access closure (150) could usefully be detachable for providing access to the lead end, or they could slide between the open and the closed positions.
