Description

[Detailed description of the invention] This invention relates to a terminal for connecting an electric wire to a battery post, and aims to reduce the weight of the terminal and automate the conflict with the electric wire by replacing the terminal with a cast lead body. The main body is manufactured by punching and bending a plate material such as brass, and by immersing the main body in a synthetic resin emulsion, the interior is filled with synthetic resin leaving a contact area, and the surface is coated. Therefore, the synthetic resin provides corrosion resistance and insulation properties, and the resin filled inside prevents deformation during tightening and the occurrence of poor contact due to this.

An embodiment of the present invention will be described below with reference to the drawings.
A indicates the terminal body, and the upper and lower double contact plate parts 1 and 2 with a gap are continuous by a bending connection part 3 provided on one side in the wire connection direction, and on the other side in the wire connection direction, An outer U-shaped crimping portion 4 for the electric wire is provided on the contact plate portion 1;
An inner U-shaped crimp portion 5 is connected to the inner U-shaped crimp portion 5 .

The upper and lower contact plate parts 1 and 2 are formed with large and small connection ports 6 and 7 for the battery post, and a reduction permitting notch 8 for the connection ports 6 and 7 is provided between the reading ports 6 and 7.

Tapered contact flanges 9 and 10 are formed around the connection ports 6 and 7 in the same direction.

A large number of grooves 11 are formed in the inner circumferential surface of the contact flanges 9 and 10 in the axial direction to improve the bite to the battery post and to obtain good contact.

Flanges 12.12 are formed at both ends of the bending connection part 3 to receive the tightening poles I-H, and the flanges 12.12 have bolt insertion holes 13 inside and bending ears 14 outside. ,14
The upper and lower contact plate portions 1 are connected by the bent ears 14, 14.
, 2, thereby positioning the bolt insertion hole 13 between the circumferential contact plate parts 1 and 2.

Branch circuit terminal plate portions 15 are provided at both ends of the lower contact plate portion 1.
15 is formed.

The receiver is tightened in the hole 13.13 of the flange 12゜12.
Insert B.

A protruding rib 16 is formed on the inner U-shaped crimp portion 5 by pressing, and the protruding rib 16 bites into the conductor to improve adhesion to the conductor.

Next, the cores are fitted into the connection ports 6 and 7 of the upper and lower contact plate parts 1 and 2 heated to a constant temperature (not shown), and the entire body is heated with a solvent, leaving the inner and outer U-shaped crimped parts 4 and 5. PV liquefied by etc.
The resin is soaked in an emulsion such as C, pulled up, dried and solidified, the core is pulled out, and the resin is cut leaving the outer mantle 19 formed by the core below the connection port 6, and compared to the surface of the terminal. A coating C of a soft synthetic resin is provided inside the coating C, and a filling layer of the resin is provided inside the coating C, except for the connection port 6.7, the inner circumference of the contact flanges 9 and 10, and a continuous space opening at the lower end in the axial direction. Provide C.

A protruding synthetic resin cap portion 20 is continuously provided above the upper connecting lower portion.

The synthetic resin coating on the branch circuit terminal plate portion 15 is stripped off as necessary.

A notch 17 is made in the end of the bolt B, and when in use, the resin coating of this part is folded back to expose the end of the bolt B, and the nut 18 is turned to tighten.

During use, the nut 18 is regulated by the synthetic resin coating so that it does not rotate randomly and loosen.

Since the present invention is constructed as described above, the synthetic resin coating or the internal filling layer provides insulation to the terminal fitting and prevents corrosion of the terminal fitting, and at the same time, it provides insulation between the upper and lower contact plate parts. The filling layer located at the upper and lower contact plates prevents deformation of the terminal fitting due to lateral displacement of the upper and lower contact plates when tightening, and also prevents the terminal fitting from being tightened due to the reduction of the reduction allowable notch. Therefore, good contact between the terminal fitting and the battery post can be ensured.

In addition, in the present invention, a synthetic resin sleeve is provided below the lower connection port, so that the sleeve completely covers the battery post during use, improving the insulation performance of the battery post. can be further improved.
