Embodiment approach

[0047] Below, refer to figure 1 Moving to FIG. 3 , an embodiment will be described.

[0048] Such as figure 1 As shown, the terminal pair 1 of this embodiment is configured to include a female terminal 10 (first terminal) and a male terminal 20 (second terminal). In the description below, the figure 1 The upper side in the middle is defined as upper (the lower side is defined as lower), the left side is defined as left (the right side is defined as right), and the side where the female terminal 10 and the male terminal 20 are fitted together is defined as the front ( Set the opposite side to back). It should be noted that the directions of up, down, left, and right are for convenience of description, and the terminal pair 1 can be used in any posture.

[0049] [Construction of Terminal Pair]

[0050] (female terminal 10)

[0051]The female terminal 10 is formed by punching a conductive metal plate including the female terminal base material 51 into a predetermined shape....

Embodiment 1

[0078]A copper alloy substrate with a plate thickness of 0.25 mm was used as the female terminal base material 51 and the male terminal base material 41 , and the first silver plating layer 53 or the second silver plating layer 43 was formed on their surfaces by electroplating. The thicknesses of the first silver plating layer 53 and the second silver plating layer 43 are both 5 μm. Carry out the mensuration of Vickers hardness as described below for these silver coatings, as a result, the Vickers hardness of the first silver coating is 113Hv, and the Vickers hardness of the second silver coating is 95Hv (the Vickers hardness of the first silver coating>th Vickers hardness of two silver coatings).

Abstract

A terminal pair (1) includes a female terminal (10) with a second contact piece (33) and a male terminal (20) provided with a tab (21). The female and male terminals (10, 20) are connected electrically by a bulging contact portion (33A) on the second contact piece (33) contacting a contact region (21A) on the lower surface of the tab (21). An outermost surface of a contact part of the bulging contact portion (33A) narrower than the contact region (21A) is coated with a first silver plating layer (53), and an outermost surface of the contact region (21A) is coated with a second silver plating layer (43) having a lower Vickers hardness than the first silver plating layer (53).

Description

technical field [0001] The technology disclosed in this specification relates to a terminal pair and a connector including the terminal pair. Background technique [0002] Conventionally, as a vehicle connector, a connector having a pair of terminals designed to have a predetermined contact pressure between a contact piece provided on a female terminal and a male terminal inserted into the female terminal has been used. Contact, and the terminal pair is electrically connected. If such a connector is used in a place with a severe vibration environment such as the engine compartment, the vibration of the vehicle will be transmitted to the terminal connection part, causing the female terminal and the male terminal to slide in the contact part, which may cause wear of the terminal and increase in resistance and / or a bad connection has occurred. [0003] As a countermeasure against such vibrations, a technique of providing a gap-filling protrusion or the like between a female ...
