A battery clamp having a first inner metal battery clamp member having a handle portion and a clamp portion, a second inner metal battery clamp member having a handle portion and a clamp portion, a first outer insulating battery clamp member having a handle portion and a clamp portion connected to the first inner metal battery clamp, and a second outer insulating battery clamp member having a handle portion and a clamp portion connected to the second inner metal battery clamp. The first inner metal battery clamp member and/or the second inner metal battery clamp member having an inclined connection plate for connection with a battery cable, the inclined connect plate configured to allow a user to access the inclined access plate with a tool while avoiding interference with the handle portions of the battery clamp.

A clamp is provided, including: the first clamp body, provided with a first jaw; a conductive bridge mechanism, for electrically connecting to an electrode and comprising a reciprocating assembly, an elastic engaging element, and an operable portion. The elastic engaging element is provided between the reciprocating assembly and the operable portion and is independent and separated from the reciprocating assembly. The elastic engaging element can be operated to move towards the reciprocating assembly. The reciprocating assembly can be mutually engaged and positioned with the elastic engaging element. When the elastic engaging element is positioned at a third position, the reciprocating assembly can be engaged by the elastic engaging element and thus be positioned at a second position so as to allow the first jaw to be electrically connected to the electrode; when the elastic engaging element is operated and positioned at a fourth position, the reciprocating element is not stopped by the elastic engaging element and can thus be automatically positioned at the first position and not electrically connected to the first jaw.

A battery clamp structure of detachable lighting lamp includes at least a battery clamp and a lamp, wherein the battery clamp includes two oppositely installed grips, with one end of each of the grips respectively having a clamp head, and the exterior of a clamp head is configured with a slide groove; in addition, the lamp includes a lighting portion, a switch and a clamp; accordingly, the clamp can be detachably assembled within the slide groove such that the lamp and the clamp head can be fixedly assembled, and, when the lamp is fixed onto the clamp head, the lighting portion faces towards the clamp head thus allowing the lighting portion to cast light at the direction of the clamp head.

A quick change battery clamp includes a first clamp body, a second clamp body, and a handle assembly. The second clamp body is coupled to the first clamp body. The handle assembly is selectively disposed through each of the first clamp body and the second clamp body. Each of the first clamp body and the second clamp body define an aperture having a substantially polygonal cross-section configured to receive a battery post. Each of the first clamp body and the second clamp body have an internal wall with a plurality of ridges configured to selectively abut the battery post. The first clamp body and the second clamp body are hingedly connected.

Herein is disclosed a jumper cable clamp which includes a housing having an elongated arm having a head portion and a second end configured to mount to the jumper cable and hold the jumper cable in coaxial alignment with the elongated axis. First and second jaws are mounted adjacent the head portion perpendicular to the elongated axis. The first jaw is electrically coupled to the jumper cable. The clamp further includes a lever assembly coupled to one of the first and second jaws for moving the jaw between a clamping position wherein the first and second jaws are sufficiently close together to clamp onto the terminal and an open position wherein the first and second jaws are sufficiently spaced apart to permit the terminal to be free from the jaws. The clamp further includes a lock mechanism for locking the first and second jaws in their clamping position.

An auto safety jumper module to prevent accidental short circuits or wrong connections between a jump start system and a motor vehicle battery when jump starting such motor vehicle. The module can be fully automatic and capable of detecting when a motor vehicle battery is connected to it. The module, which can be integrated into or an external add-on to a jump start system, does not need an external sensing wire(s) to detect when alligator clamps of the jump start system are connected to a vehicle battery post or to detect when the alligator clamps are disconnected.
