Problems solved by technology

However, Fe or Fe-based alloys have extremely low corrosion resistance compared to brass, etc.
Therefore, this type of connector terminal has a problem that it is easy to corrode even if a little metal base material is exposed.

Embodiment 1

[0031] use figure 1 and figure 2 The connector terminal of the first embodiment will be described. Such as figure 1 and figure 2 As shown, the connector terminal 1 is composed of a terminal material 2 having a plated film 22 on the surface of a metal base material 21 .

[0032] In this example, specifically, as figure 1 As shown, the connector terminal 1 is a female terminal, and is used in a connector (not shown) included in a wiring harness for an automobile. More specifically, the connector terminal 1 has a rectangular cylindrical fitting portion 11 and a cylindrical portion 12 connected to the fitting portion 11 .

[0033] An anode piece portion included in a male terminal (not shown) serving as a counterpart terminal to be electrically connected is inserted into the fitting portion 11 . Inside the fitting portion 11 , an elastic contact piece 111 is formed by folding the bottom plate portion of the fitting portion 11 inward and rearward. A contact part (not sh...

Embodiment 2

[0043] use image 3 and Figure 4 The connector terminal of the second embodiment will be described. Such as image 3 and Figure 4 As shown, the terminal 1 for a connector of this example is a pin terminal and has a substantially "L-shaped" terminal shape. Specifically, the terminal 1 for a connector is used in a substrate connector (not shown) applied to a PCB.

[0044] More specifically, the connector terminal 1 of this example is produced through the following steps: cutting the linear terminal material 2 into a predetermined length, and performing bending processing of bending 90° at the middle part of the cut piece to form the bent portion 32 . In addition, the terminal 1 for a connector can also be produced through the following steps: punch out the plate-shaped terminal material 2 to form a punched piece, and perform a bending process of bending 90° at the middle part of the punched piece to form a bent portion. 32.

[0045] In the terminal 1 for a connector, th...

experiment example

[0048] Hereinafter, it demonstrates more concretely using an experimental example.

[0049] Prepare a plate-shaped terminal material in which a Sn plating film (thickness 1.2 μm) composed of reflow-plated Sn is formed on the surface of a plate-shaped metal base material (plate thickness 0.3 mm), wherein the mass % of the metal base material contains 0.4% C , and the remainder is composed of Fe and unavoidable impurities.

[0050] Next, a raw material sheet capable of constituting a 0.64-type female terminal shape is punched out from the plate-shaped terminal material by a punching machine, and the raw material sheet is bent to obtain a 0.64-shaped female terminal. In addition, the metal base material was exposed on the punched out surface of the obtained female terminal. In addition, the plated film of the obtained female terminal was cracked at a part of the bent portion, and the base metal was exposed at the cracked portion.

[0051] A coating film was formed by applying a...

Abstract

Provided is a terminal (1) for connectors which is capable of having improved corrosion resistance even in cases where a metal base material (21) is composed of Fe or a Fe-based alloy. This terminal (1) is configured of a terminal material (2) that has a plating film (22) on the surface of the metal base material (21). The metal base material (21) is composed of Fe or a Fe-based alloy. The terminal (1) has a base material exposed part (3) where the metal base material (21) is exposed and a coating film (4) that is composed of rust preventive oil covering the surface of the base material exposed part (3). The base material exposed part (3) is configured to be present in a punched fracture surface (31) that is formed by punching the terminal material (2) and / or in a bent part (32) that is formed by bending the terminal material (2).

Description

technical field [0001] The present invention relates to a terminal for a connector. Background technique [0002] Conventionally, connector terminals having various shapes have been used in connectors used in vehicles such as automobiles. Terminals for connectors are generally composed of a terminal material having a Sn plating film on the surface of a copper alloy such as brass in many cases (see Patent Document 1). [0003] prior art literature [0004] patent documents [0005] Patent Document 1: JP-A-2012-185984 [0006] In recent years, in order to reduce the weight, size, and cost of the entire connector, there has been a demand for connector terminals that have higher rigidity and can reduce material costs. Therefore, it is considered to use Fe or an Fe-based alloy having high material strength and low material cost as the metal base material of the connector terminal. In this case, in order to improve the connection reliability, it is effective to form a plat...
