Problems solved by technology

When the spring portion is formed to increase the contact force, the force (terminal insertion force) required to insert the male terminal into the female terminal increases, and there is a problem that the male terminal is difficult to insert.
[0023] On the other hand, due to Figure 11 The male terminal 50 is a flat plate shape, which has poor heat dissipation due to its small surface area
Therefore, there is a problem that the temperature of the terminal rises when a large current is energized, which affects the resin shell of the connector and peripheral equipment.
At this time, it is very difficult to bend the square-shaped terminal into an L-shape for use, since it is very difficult to generate cracks, etc., and the above-mentioned problems cannot be solved.

Embodiment Construction

[0051] Below, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0052] figure 1 — Figure 4 is a diagram showing a preferred embodiment of the female terminal of the present invention, figure 1 is a stereogram, figure 2 is a vertical perspective view, image 3 is a top perspective view, Figure 4 It is a cross-sectional perspective view.

[0053] Such as figure 1 — Figure 4 As shown, the female terminal 30 has a terminal current-carrying portion 31 that can be inserted into the male terminal 10 and is made of a high-conductivity material. A spring portion 33 for fixing the inserted male terminal is provided in the terminal energization portion 31 . The female terminal 30 is characterized in that the terminal case 32 is provided so as to cover the terminal energizing portion 31 using a material stronger than a highly conductive material, and the spring portion 33 is integrated with the terminal...

Abstract

The object of the invention provides a male terminal structure with good heat dissipation at the time of large current flow. The male terminal structure comprises an electric wire connection part 13 to be connected to an electric wire at one end, and an insertion contact part 12 formed in frame shape to be inserted into a female terminal at the other end. The cross-section of a flat-shape plate member of the insertion contact part 12 is formed in U-shape.

Description

[0001] The application is a divisional application. The filing date of the original application is November 29, 2006, the application number is 200610162901.6, and the invention name is female terminal and male terminal structure. technical field [0002] The present invention relates to an electrical terminal structure for passing large current, in particular to a female terminal structure of a connecting piece inserted and connected to a male terminal piece and the inserted male terminal structure. Background technique [0003] At present, a hybrid electric vehicle (HEV-Hydrid Electric Vehicle), which can reduce the emission of harmful gases and greatly reduce fuel costs, is attracting great attention. The motor that drives the HEV and the inverter are connected through a connector, and a large current of 100A or more is carried out by the HEV system. With the advancement of the electrical control technology of automobiles, although connectors are widely used in automobile...
