Description

[Detailed description of the invention] The present invention relates to an improvement of the insertion plug receiving terminal.The purpose of the invention is to have a simple structure and to minimize the contact area and contact pressure with the mating column connector for electrical connection. It is an object of the present invention to provide an insertion plug receiving terminal which can be used reliably and has a relatively large current capacity.

Both sleeve pieces of a conventionally used conductive metal plate are bent inwardly to form an arc-shaped bent contact piece 12 facing the bottom plate 11.
, 13 integrally formed, the conventional plug socket terminal shown in FIG.
When the mating plug connector is inserted and connected between the two and When used as a stopper terminal for auto fuses, etc., there are defects such as creep deformation of the insertion connector made of soft material, and the small contact area with the plug connector, which causes it to easily generate heat. In addition, the plug-receiving terminal shown in Fig. 2, which is made by folding a conductive metal plate in half and folding the leading edge inward to integrally form contact pieces 14 and 15 facing each other, makes contact with a mating connector. Due to low pressure, abnormal connections, and long-term use, the contact pieces 14 and 15 that face each other become fatigued, causing the contact pressure to weaken and generate heat.

The present invention was conceived in view of the above circumstances, and one embodiment of the present invention will be described below with reference to the drawings.
In the figure, 1 is a plug socket terminal, which is made by bending a conductive metal plate with a large elastic limit such as tin-plated or other surface-treated brass, phosphor brass, aluminum copper, etc., and attaching it to the rear end. A crimp part 2 for connecting electric wires is formed, one wide sleeve piece integral with the metal plate is curved inward at the tip, and the extended end of this curved part 3 is further bent at a right angle to be parallel to the bottom plate 4. A contact plate 5 is formed, and the tip part 7 of a curved part 6 formed by bending the other sleeve piece inwardly into an arc is brought into contact with the end part of the contact plate 5. 4 and the contact plate 5, when the mating plug connector is inserted, the left and right bent curved portions 3 and 6
This allows a large contact pressure to be applied evenly to the connectors.

The present invention is constructed as described above, and is formed by bending both wide sleeve pieces at the tip of a conductive metal plate having spring properties inwardly, and further bending the extended end of one curved part 3 at a right angle. Since the mating column connector is inserted and connected between the contact plate 5 and the bottom plate 4 parallel to the contact plate 5, the contact area with the plug connector is large, and the inserted plug connector for,
The curved portion 3 formed at the base of the contact plate 5 and the other curved portion 6 whose tip is brought into contact with the end portion of the contact plate 5 apply a large and uniform contact pressure to the contact surface, so that electrical It has excellent effects such as low contact resistance, no risk of creep deformation in the plug socket or generation of heat even when a large current is applied, simple structure and low cost. .
