Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connection structure between a battery terminal and a tab terminal, and more particularly to a structure of a connection portion of a tab terminal into which a battery terminal connection board portion having a U-shaped cross section is to be fitted.

For batteries used in automobiles, the connection between the battery terminal fitted in the panteri post and the tab terminal connected to it is made by touching the contact surfaces of both terminals and inserting a bolt into the bolt insertion hole provided in this. It has a structure in which it is inserted and connected by tightening with a nand. In the above tightening, the battery terminals are fixed to the battery posts collinearly.

Typical battery terminals are, for example, Utility Model Application No. 56-2136.
As proposed in Publication No. 5, there is a crimping part bent into a substantially circular shape to be attached to a chisel post, and a sleeve piece extending from this, one of the sleeve pieces has a base plate part and a wire crimping part at the end. The other sleeve piece is provided with a connection board portion. A tab terminal is attached to the connection board section. The bolt insertion hole is bored in the center of the base plate of the sleeve piece.

The substrate portion is formed into a U-shaped cross section by bending both side edges outward. This shape effectively serves to increase the cross-sectional area of the battery terminal, provide strength, prevent the tightening bolt from rotating, improve workability, and stabilize the tab terminal connection portion.

Thus, together with the tab terminal connection part, the bolt and NAND inserted into the battery terminal port insertion hole can be used to
It is collinear with the tightening of the above-mentioned crimp part to the post.

In the above-mentioned known tab terminal connection, since the bolt tightening between the battery terminal and the tab terminal depends on the state, there is a risk of poor continuity due to poor tightening or loosening due to vibrations or other factors that occur during use.

The present invention has been made in view of the above points, and an object of the present invention is to provide a connecting means that makes the connection of tab terminals even more reliable, and to improve the reliability of this type of connecting member.

The present invention provides a tab terminal in which a connecting plate portion of a battery terminal having a U-shaped cross section is connected to a connecting portion of a tab terminal by fitting, in which a connecting portion of the tab terminal is connected to a connecting portion of the connecting board portion. The above-mentioned tab terminal is provided with a U-shaped contact that contacts the inner surface of the U-shaped, and an arm portion is provided extending from the contact along the U-shaped outer surface of the connection board portion. It is characterized by a connection structure.

Therefore, the U-shaped battery terminal connection board part is fitted into a tab terminal connection part having a correspondingly shaped gap, and the arm extending from the contactor is inserted into the tab terminal connection part with a bolt inserted therethrough so as to be aligned with each other. The connecting board part can be elastically clamped by providing a protruding part that is recessed inward on the outer surface contact part of the part. In such cases, contact can be reinforced and ensured.

Next, embodiments of the present invention will be described together with tooth surfaces.

Referring to FIGS. 1 and 2, the battery terminal 2 has a crimp portion 3 bent into a substantially circular shape that is fitted into the panteri boss l-1, one of the legs extending from the crimp portion 3 has a base plate portion 4, and a wire crimping portion. 7 and to which an electric wire 8 is connected, and the other member includes a contact board portion 5. The above board parts 4 and 5
A central bolt insertion hole 6 is opened, and a tab terminal 11 (to be described later) is attached using a bolt 9 and a nut 1o, and a battery terminal 2 is attached to a post +-i on the same line.

The substrate parts 4 and 5 are formed into a U-shaped cross section by bending both upper and lower edges outward. That is, especially the connection board section 5
As can be seen in detail in , an upper surface bent portion 5a and a lower surface bent portion 5b are shown, and an end bent portion 5C bent inward is provided.

The tab terminal 11 is a contact 1 that is brought into contact with the connection board section 5.
3, and a connector portion 12 is provided at the other end. The connector portion 12 may have any desired shape as necessary.

In the contactor 13, the upper and lower edges of the contact surface 13a that abuts the contact base portion 5 are bent into an upper surface bent portion 15 and a lower surface bent portion 16, and the outer surfaces of the upper and lower bent portions 15 and 16 are respectively bent. The upper surface bent portion 5a and the lower surface bent portion 5 of the contact substrate portion 5
It is provided in a size that is inscribed in b.

Furthermore, the other ends of the upper surface bent portion 15 and the lower surface bent portion 16 are folded back to provide an upper arm portion I7 and a lower arm portion 18. That is, the arm portions 17 and 18 extend along the U-shaped outer surface of the connection substrate portion 5, and their terminal portions surround the connection substrate portion 5 from the outside. The tips of the upper arm part 17 and the upper arm 18 are separated from each other, and an end bent part 5C is provided between them so as to be able to pass therebetween.

In the illustrated example, the upper arm portion 17 is hollow, and the claw 1
7b are provided to serve as upper and lower pressers, and the center portion of the tip edge of the arm portion 17 is made to protrude inward to make the surrounding of the contact base portion 5 elastic 1 and to ensure the contact of the contact surface 13a. A bolt insertion hole 14 is provided in the center of the contact surface 13a at a position that matches the bolt insertion hole 6 provided in the battery terminal 2.

When using the tab terminal 11 provided with the above-mentioned contactor 13,
The connection board portion 5 having a U-shaped cross section has a tab terminal 11.
The contact surface 13a, the upper and lower bends 15 and 16, and the upper and lower arms 17 and 1B fit into a gap of a corresponding shape. The bolt 9 and nut 10 are then tightened.

Referring to FIG. 3, a connecting portion of the tab terminal according to another embodiment is shown.

Both upper and lower edges of the contactor 13 are bent into an upper surface bent portion 115 and a lower surface bent portion 116, and the other ends thereof are folded back to provide an upper arm portion 117 and a lower arm portion 118. That is, the arm parts 117 and 118 extend along the U-shaped outer surface of the connection board part 5, and their terminal parts surround the connection board part 5 from the outside. The tips of the upper arm part 117 and the lower arm Its 118 are separated from each other, and an end bend jHB5C is provided between them to allow passage.

The upper and lower arm portions 117 and 118 are both hollow, and the center portions of the tip edges of the arm portions 117 and 118 are made to protrude inward, and protrusions 117a and 117b are provided to connect the connection board portion 5.
The surrounding area is made elastic and the contact of the contact surface 13B is ensured.

As shown above, in accordance with the present invention, the connecting portions of the battery terminal and the tab terminal have a U-shaped cross section and are equivalent to each other, and the conventional battery terminal is fitted and connected without changing. The strength of the connection part is improved, the contact surface area is increased, and the contact of the connection 91i itself is ensured by press-fitting if necessary.

Therefore, even if the bolt is loosened due to vibration or the like, there will be no conduction failure between the battery terminal and the tab terminal.
