Embodiment Construction

[0008] The present invention will be further described below in conjunction with the accompanying drawings.

[0009] Such as figure 1 and figure 2 As shown, both ends of a single or double constantan wire 1 are connected to a brass sampling terminal 2, and the two brass sampling terminals are respectively provided with a 4mm data line hole 3 and a 6mm fixing hole 4. Among them, the single type is suitable for small current; the double type is suitable for large current.

[0010] The present invention is designed for a relatively large current of 25A--125A, and is suitable for connecting cable joints and sampling data lines. The two ends are made of brass material with good conductivity, and the middle is made of constantan wire. You can choose wires of different thickness to make sampling resistors with different currents.

[0011] The above-described embodiments are only described to the preferred implementation of the present invention, and are not intended to limit the ...

Abstract

The invention discloses a heavy-current sampling resistor. The adopted technical scheme is as follows: two ends of single or two constantan wires are connected with brass sampling ends; and a data line hole (4mm) and a fixed hole (6mm) are respectively arranged on the two brass sampling ends. The heavy-current sampling resistor is designed for higher current (25A-125A) and is applicable to connection of cable joints and sampling data lines; and the single wire suitable for low current and the two wires suitable for high current are adopted in the middle of the resistor, thus the resistor can adapt to wider current range.

Description

technical field [0001] The present invention relates to the field of adopting resistance components, more specifically, relates to large current sampling resistors. Background technique [0002] At present, there are many resistance specifications used in cable joints and sampling data line connections, but there are few sampling resistance products that can be adapted to relatively large current designs of 25A--125A. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a large current sampling resistor by overcoming the deficiencies in the prior art. [0004] The high-current sampling resistor of the present invention is realized through the following technical scheme. The two ends of a single or double constantan wire are connected to a brass sampling terminal, and the two brass sampling terminals are respectively provided with a 4mm data line hole and a 6mm Fixing hole. [0005] The present invention is designed ...
