Description

[Detailed Description of the Invention] The present invention relates to a battery terminal connecting fitting that can be easily attached and detached with a one-touch operation.

Conventionally known battery terminal connection fittings are
A series of through holes are formed at the distal end of the bifurcated clamping piece to which the lead wire is connected to the base end, and a bolt is inserted into the through hole and a nut is screwed onto the bolt. By tightening the nut, the battery terminal was clamped and fixed by the clamping pieces. Therefore, according to this connection fitting, installation and removal can be done by biting the bolt head and nut with a tool such as a hex wrench or spanner, and rotating the tool to tighten the bolt and nut.
Or had to be loosened. For this reason, it takes time and effort to connect and disconnect the battery, especially when it is used only during busy farming seasons such as tractors, and it is recommended that the battery terminal be disconnected when not in use to avoid battery consumption. In the case of agricultural equipment, etc., it is extremely troublesome to attach and detach the attachment and detachment frequently. Furthermore, it becomes even more difficult when the thread grooves of the bolts are rusted due to the influence of battery fluid, etc.

The present invention eliminates these conventional drawbacks and makes it possible to easily attach and detach the connecting fitting to the battery terminal with a one-touch operation. A nut is screwed onto one end of the screw shaft inserted into the through hole, and an eccentric cam is rotatably supported on the other end of the screw shaft so as to be rotatable within a plane including the screw shaft, and a handle is inserted from the eccentric cam. When the eccentric cam is rotated, the tip of the clamping piece is clamped between the eccentric cam and the nut from both outside sides.

An embodiment of the present invention will be described below with reference to the drawings. In the figure, 1 is a cylindrical battery terminal protruding from the top surface of the battery main body 2, and 3 is a lead wire 4 connected to the base end, which is formed into a bifurcated shape so as to be clamped around the battery terminal 1. With a clamp piece,
A through hole 6 is provided in the bisected tip portions 5, 5 of the clamping piece.
form 6. Reference numeral 7 denotes a screw shaft inserted into both through holes, a screw groove 8 is carved near one end of the screw shaft, a nut 9 is screwed into the screw groove, and the other end of the screw shaft 7 is provided with a screw groove 8. A support shaft 10 is provided to protrude in a direction orthogonal to the screw shaft, and an eccentric cam 11 is supported on the support shaft so that the eccentric cam can rotate freely within a plane containing the screw shaft. And the eccentric cam 1
A handle 12 is integrally provided with the handle 1, and by rotating the handle, the eccentric cam 11 is rotated. Further, 13 and 14 are washers inserted into the screw shaft so as to be brought into close contact with the outer surfaces of the tip portions 5 and 5 of the clamping piece 3, and the outer peripheral edge of the eccentric cam 11 is in contact with the washer 14. .

According to the connecting fitting configured in this way, when the handle 12 is rotated in the direction of arrow A from the state shown by the solid line in FIG. The tip portion 5 rotates together as a fulcrum to press the washer 14 that abuts the outer peripheral edge of the eccentric cam and pulls the screw shaft 7.
The battery terminal 1 can be fixed by narrowing the gap between the terminals 5 and 5 and clamping the battery terminal 1 into the clamping piece. Moreover, if the handle 12 is rotated in the opposite direction, the elasticity of the clamping piece 3 opens the tip portions 5, 5, and the battery terminal 1
It can be removed from the

By adjusting the screwing position of the nut 9, it is possible to appropriately adjust the clamping force to the battery terminal 1 when the eccentric cam 11 is rotated.

As explained above, the battery terminal connection fitting of the present invention allows the clamping piece to be easily and quickly attached to or removed from the battery terminal by simply rotating the handle. It has extremely high practical value and is industrially useful, as it can significantly shorten the required working time, requires almost no labor, and does not require any tools.
