Plate type truck jumper wires (connecting wires for batteries) DJ Series
Plate type truck jumper wires (connecting wires for batteries)
DJ Series
Achieve both environmental performance and high performance
In recent years, engine and brake-system of large size vehicles become electronic control basis and certain control under low power electric supply is required in harsh environment.
Our 'Oxygen-free Copper' Battery Terminal realized high level environmental/efficiency performances and gets a favorable reputation of automobile mechanics.
Proof of safety & confidence: "MADE IN JAPAN". We have developed plate type truck jumper wires (connecting wires for batteries) which first adopted "oxygen-free copper" with excellent conductivity as a terminal material in Japan. They are gaining a high reputation as the environment-friendly products having excellent characteristics that meet the requirements of professional mechanics.  
Oxygen-free copper having high copper purity and outstanding conductivity is adopted for the material of plate type battery terminal.
Malleability: The property of material to evenly stretch and extend without being destroyed, even when it is pressed and stretched beyond its elastic limit.
* 1.  Material conductivity refers to the internationally adopted standard annealed mild copper as a standard of electric resistance, which is specified as 100%IACS conductivity.
* 2.  Above values are just general reference values (standards), not absolute values (guaranteed values)
Usage environment grades specified in Automobile parts-General rules of electroplating Usage environment JIS grade for each plating type specified in Automobile parts-General rules of electroplating
Usage environments of plated products are classified into the above listed four grades
* 1.  No description on usage environment grade for copper plating under Automobile parts - General rules of electroplating
* 2.  Brass plating is omitted due to no stipulation under Automobile parts - General rules of electroplating
We employ the concept of "thickening" and "structure without slits" from a development stage so that our plate type truck jumper wires (connecting wires for batteries) can fully function in the harsh environment of large vehicles.
The cracked battery terminal can causes 'contact
failure' and 'Voltage reduction' and fall into the
troubles of the vehicles.
The following image shows a single product of battery terminals with slits.
For our plate type truck jumper wires (connecting wires for batteries), we have developed RoHS Directive-compliant products which do not use any hazardous substances such as "lead, mercury, and cadmium" first in the industry. We have implemented environment-friendly manufacturing of these products which satisfy the needs of the times as well as support the preservation of the global environment.
We have developed flexible electric wires under our original specifications to meet the request from the market which demanded "plate type truck jumper wires (connecting wires for batteries) with more flexible wires".
Beneficial advice for using the products
Storage batteries installed in large vehicles such as trucks and buses have especially large vibrations transmitted from the vehicle. We therefore recognize that our plate type truck jumper wires (connecting wires for batteries) need to have performance/function resistant to use in the harsh environment. We adopt a secure crimping method using a press to ensure high reliability.
Fully exhibit its intrinsic storage battery performance in the harsh environment by press crimping battery terminals and electric wires more securely.
Reference: Verification of the tensile strength at the crimp part of electric wires
The terminals employed in our plate type truck jumper wires are "open type". Since the Crimp-type terminal lugs for copper conductors specified in the JIS Standards are "closed type", the above actual values are only for reference.
