Description

[Detailed description of the invention] This invention relates to a terminal for connecting electric wires to a battery post, and aims to reduce the weight of the terminal and automate assembly with electric wires by replacing the terminal with a cast lead body. For this purpose, 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 welded part, and the surface is The synthetic resin provides corrosion resistance and insulation, and the resin filled inside prevents deformation during tightening and the occurrence of poor contact due to this. A folded covering part with a notch is provided in the part of the resin coating that corresponds to the end position of the tightening bolt, and the tightening operation is made possible, and the folded covering part engages with the bolt head or nut during use. By preventing the terminal fitting from rotating, the terminal fitting is prevented from loosening with respect to the battery post.

An embodiment of the present invention will be described below with reference to the drawings.
A indicates a terminal housing body, in which upper and lower double contact plate parts 1 and 2 with a gap are connected 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 portions 1.2 are formed with large and small connection ports 6, 7 for the battery post, and a reduction permitting notch 8 for the connection ports 6, 7 is provided between the reading ports 6 and 7.

Around the connection port 6.7, tapered contact flanges 9, 10 are formed which taper 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 the QIl end of the bending connection part 3, and the flange 12, 12 has a bolt insertion hole 13 inside, and a bending lug 14. 1
4, and the bent tabs 14.14 span the upper and lower contact plate parts 1, 2, thereby positioning the bolt insertion hole 13 between the two liquid contact plate parts 1.2.

Branch circuit terminal plate portions 15 are provided at both ends of the lower contact plate portion 10,
15 is formed.

The receiver is a tightening bolt B in the hole 13.13 of the flange 12.12.
Insert.

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, fit the core into the connection port 6.7 of the upper and lower contact plate parts 1 and 2 heated to a constant temperature (not shown), leaving the inner and outer U-shaped crimp parts 4 and 5, and press the whole P liquefied by solvent etc.
Soak it in an emulsion such as VC, pull it out and dry it,
The resin is solidified, the core is extracted, and the resin is cut leaving the outer mantle 19 formed by the core below the connection port 6. A relatively soft synthetic resin coating C is provided on the surface of the terminal, and the interior thereof is A filled layer C' of the resin is provided except for a continuous space opening at the inner circumferential portions of the connection ports 6, 7 and the contact flanges 9, 10, and at the lower end in the axial direction thereof.

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

The resin coating on the branch circuit terminal plate portion 150 is peeled off as necessary.

A notch 17 is made in the end of the bolt B, and when in use, the folded covering part 17' formed by the notch 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 attached to the folded covering portion 17'.
It is regulated by , so it will not rotate erratically and come loose.

Since the present invention is 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 has a double upper and lower contact plate. The filling layer located between the parts prevents deformation of the terminal fitting due to lateral displacement of the upper and lower contact plate parts during tightening, and also prevents the terminal fitting from being tightened due to the reduction of the reduction allowable notch. The operation is not obstructed, and thus good contact between the terminal fitting and the battery post can be ensured.

! In the present invention, since the folded coating part is provided by a cut in the coating corresponding to the end position of the tightening bolt, it is convenient for tightening operations of the tightening bolt, and the folded coating part is provided during use. has the effect of preventing the tightening bolt from loosening.
