Abstract: An insulation displacement contact (IDC) strain relief cap is employed to interconnect a wire with an electrical contact. The electrical contact has a bifurcated end to engage and retain a wire and may be engaged with the strain relief cap. The cap contains notches, some of which fit on retaining cams that are attached to the electrical contact while others serve as wire exit holes. The cap fastens onto the clip once the retaining cams engage the notches and once the wire is aligned with the appropriate exit hole.

In the closed position, the first and second body sections latch together to form a hollow body open at a first end and having a top wall at a second end which defines a conductor opening. A spring assembly biases the first and second body sections toward the closed position, and a releasable trigger extends between the first and second body sections to hold them in the open position until the trigger is released. A wire stop formed on the first and second body sections bridges a gap therebetween in the open position to retain a bushing lead wire in the conductor opening.

Abstract: A cover of a simple construction is provided which can deal with a distance variation between battery posts. The cover 6 is made of a rubber material and has a narrow box-like configuration. A bottomed middle portion of the cover 6 forms a tubular portion 107 through which a braided wire 3 of a battery connection terminal 1 is to be passed, and the opposite ends thereof form post cover portions 108 for covering battery posts 2. Further, slits 9 are formed in side walls between the tubular portion 107 and the post cover portions 108, so that the post cover portions 108 can be bent upward. In this way, since the cover 6 can be elongated and contracted according to a distance between the battery posts 2, it can be easily mounted and the action of an undesired force on the cover 6 due to the vibration of batteries 5 can be effectively prevented.
