Structure of jumper cable clamp
First Claim
1. A jumper cable clamp, including one pair of clamping elements, a guide block set in one of the said clamping elements, said guide block having a slide way in which a conductive charging clip is set, said conductive charging clip being connected with an expansion spring at the bottom, which expansion spring has its other end connected to said guide block so as to let the conductive charging clip be pulled out for operation or retreated back to be received inside said clamping element, said conductive charging clip having a curved opening made at the middle part to serve as an electrical connector clamping means for use to clip on the positive or negative side-mounted terminal of a car battery for electricity transmission.

Abstract
This invention is to provide a new structure of jumper cable clamp to connect car batteries, which includes a conventional clamp having an insulated guide block set in one of the two clamping elements, which guide block is comprising a guide way for setting therein of a conductive charging clip, which conductive charging clip is further connected with an expansion spring, which expansion spring is further connected with an indicator lamp. When in use, the conductive charging clip may be pulled out and firmly engaged by the metal clamping jaw of the opposite clamping element, such that the conductive charging clip is served to clip on the battery terminal. Further, the indicator lamp will be turned on to give a warning signal if the clamp is secured to the wrong battery terminal.
