Battery terminal

Playte type battery terminal


The proof of confidence and reliance: "MADE IN JAPAN"
From planning to manufacturing, we adhere to domestic products and inquire the high quality and reliance.
We have been supplying automotive appliances to mechanics for more than 30 years, and make good use of experiences to the products.

Remarkable point 2

We adopted the material of terminal "Oxygen-free copper" which contents pure copper and its secular change of material is low level, and its conductivity exceeds the IACS level.

What is Oxygen-Free Copper?

MaterialComponentFeatureExamples of material use
Oxygen-Free Copper
(JIS:C 1020)
Copper content rate:
99.96% or more
High-purity copper having properties of excellent conductivity, in which impurities contained are reduced to the minimum.

It is often used as a material for electronic components, which has excellent malleability, fatigue resistance, corrosion resistance, and weather resistance.
Parts used for wiring circuit connection of generators, switchboards, audio equipment, etc.

*Malleability: The property of material to evenly stretch and extend without being destroyed, even when it is pressed and stretched beyond its elastic limit.

Material conductivity

*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)

Remarkable point 3

To fulfill the battery' s function under the harsh environment in the engine room, we investigated 'the increment of the thickness' and 'slitless structure' of the battery terminals.

Development conceptReason and background
Thickness of terminal
  1. Improvement of durability
  2. Improvement of electro conductivity

*Synergistic effect of Oxygen free copper

Slitless structure
  1. Improvement of durability
  2. Prevent from contact failure and voltage reduction because of the cracks of the slit
Reference: Verification of practical use examples of battery terminals with slits

The cracked battery terminal can causes 'contact
failure' and 'Voltage reduction' and fall into the
troubles of the vehicles.

Remarkable point 4

Our Plate-type battery terminals do not contents any hazardous chemical substances like lead, mercury, cadmium and based on the RoHS directive. We are manufacturing the ecological products to answer the needs of the age and supporting the environmental preservation.

One point advice in the case of using battery terminal

We recommend 'crimping' when you connect the battery terminal to electric wire, which is fully relied by the mechanics.

Our original crimping tools as 'D-19N & D-20N' enable to do the relief and secure crimping operation and its minimal tensile strength of the crimping point exceeds the JASO standard.

Verification of ross-sectional shape of crimping

D-19N and D-20N exceed the JASO standard of minimal tensile strength

Plate type battery terminal

Electrical wire

Fully exhibit its intrinsic storage battery performance by installing (crimping) battery terminals and electric wires more safely and more securely.

Engine vibration and traveling vibration of automobiles have an effect on the connection between "battery terminals" and "electric wires", causing voltage reduction and contact failure due to loosened connection. It also may cause death of battery or malfunction of electronics, so it is important to perfectly connect (crimp) battery terminals with electric wires.

JASO tandards: Industrial standards established by a public interest incorporated association called "the Society of Automotive Engineers of Japan (JSAE)"
