Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a battery post terminal for connecting a cable to a battery post.
This is a combination of branch terminals.

[Conventional technology]

In automotive electrical circuits, battery post terminals are used to connect the main power supply battery cable to the battery post, and if necessary, a branch terminal for the sub power supply cable is connected to the battery post. It is coupled to the battery post terminal.

Typical battery post terminals are, for example, as proposed in Japanese Utility Model Application Publication No. 56-21365.
It has a crimp part bent into a substantially circular shape to be attached to the battery post, and a pair of opposing leg pieces extending outward from the free end of the crimp part, one of the leg pieces being a tightening board. It has a caulking part for connecting electric wires at the end following the part, and the other leg piece is configured as a base plate part for tightening and also as a connection part for the branch terminal.

A pair of opposing fastening base plates are each formed into a U-shape in longitudinal section by bending the upper and lower side edges outward, and the U-shaped structure provides strength to the base plate and is also bent. The upper and lower side edges prevent the tightening bolt from rotating, and also stabilize the installation state of the branch terminal.

Then, combine such branching terminals by positioning them between the upper and lower bent side edges of one of the tightening substrates, and align the opposing tightening substrate and branching terminals at the corresponding positions. A bolt inserted through the through hole formed in is tightened with a nut to fix the battery post terminal to the battery post via the crimping part, and also fix the branch terminal to the battery post terminal.

Next, the configuration of the present invention will be specifically explained with reference to drawings showing embodiments.

In FIGS. 1 and 2, 2 is a battery post terminal, which is formed by punching and bending a conductive metal plate. This battery post terminal 2 has a crimp part 3 bent into a substantially circular shape that is fitted into the battery post 1, and a cable connection part 7 following a tightening board part 4 on one of the legs extending from the crimp part 3. It is comprised of a member to which the cable 8 is connected, and a tightening and connection board part 5 on the other side. Bolt insertion holes 6, 6 are drilled in the centers of the board parts 4, 5, and bolts 9 and nuts 10 are used to attach branch terminals 11, which will be described later, and to attach battery post terminals 2 to post 1. be done.

The substrate parts 4 and 5 are formed into a U-shaped cross section by bending both upper and lower edges outward. That is, as can be seen in detail in the tightening/connection board portion 5, an upper surface bent portion 5a and a lower surface bent portion 5b are formed, and the free end thereof is bent inward to form an end bent portion 5c. It is being

The branching terminal 11 has a contact board part 13 at one end of the board part 12 that contacts the tightening/connecting board part 5, and a plurality of terminal parts 14 to be inserted into a connector housing (not shown) at the other end. is provided.
The terminal portion 14 can be formed into a desired shape if necessary.

Both upper and lower edges of the contact substrate part 13 that come into contact with the tightening/connection board part 5 are bent outward as an upper surface bent part 15 and a lower surface bent part 16, and the upper and lower bent parts 1
The outer surfaces of 5 and 16 are respectively the above-mentioned tightening and connection board parts 5.
It is provided in a size that is inscribed in the upper surface bent portion 5a and the lower surface bent portion 5b.

Furthermore, the bent portion 15 and the lower surface bent portion 16
The free edges of each are folded inward in a U-shape to form an upper arm portion 17 and a lower arm portion 18. That is, the arm portions 17 and 18 extend along the U-shaped outer surface of the tightening and connecting board portion 5, and their terminal portions extend along the U-shaped outer surface of the tightening and connecting board portion 5.
surround from the outside. The tips of the upper arm part 17 and the lower arm 18 are separated from each other, and the bent end part 5c of the battery post terminal 2 is provided between them so as to be able to pass therethrough.

In the illustrated example, the arm portion 17 is hollow, provided with elastic claws 17b to serve as upper and lower pressers, and with the center portion of the tip end of the arm portion 17 protruding inward to secure the tightening and connection board portion 5. The surrounding area is made elastic to ensure the contact of the contact substrate part 13. A bolt insertion hole 6' is provided in the center of the contact substrate portion 13 at a position that matches the bolt insertion hole 6 provided in the battery post terminal 2.

In the above configuration, battery post terminal 2
