Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a battery electrical connection device for connecting to a battery post. It is something.

0002

[Conventional technology]

Used as an electrical connection tool for connecting batteries and on-board electrical components in automobiles, etc. Conventionally, the system shown in FIG. 1 has been proposed. In the figure, 1 is a battery ( This is a connection terminal that is fastened to the post 2 (not shown) and is crimped to the circumferential surface of this post 2. The crimping part 3 is bent into a substantially circular shape, and a predetermined bonding friction force is applied to the crimping part 3. It consists of a fastening part 6 that is tightened with a bolt and nut 5 so that the And concluded A cable 7 for distributing power to electrical components (not shown) is connected to the section 6. Also, 8 is Batte This is an auxiliary terminal for distributing power directly from the battery to other electrical components. A connector that is fastened together with the connection terminal 1 and has a cable 9 connected to the auxiliary terminal 8. 10 can be fitted.

[Problem that the idea aims to solve]

However, in such conventional battery electrical connectors, the connection terminal 1 over the battery post 2, and press the connection terminal 1 onto the circumferential surface of the post 2. For tightening, bolts 4 and nuts 5 are tightened, but the axial direction of these bolts and nuts is Because it is perpendicular (horizontal) to the axial direction (vertical) of the battery post , the tightening work of the bolt and nut must be done on the side of the connection terminal 1. .

0004 Therefore, a large number of devices are installed in the engine room where they are crowded together. Tighten the horizontal bolts and nuts 4 and 5 to the battery post 2 and connect the connection terminal 1. When working to pressure-weld bolts and nuts, the tool used to tighten the bolts and nuts may not be connected to the battery. The tightening of bolts and nuts may be interrupted by equipment or units installed nearby. This causes problems such as insufficient tightening force and poor contact. was there.

[0005]

[Means to solve the problem]

The present invention was developed by focusing on such conventional problems, and it The axial direction of the bolt and nut to be pressed into contact with the ripost should be aligned with the axial direction of the battery post. so that the bolts and nuts are tightened at the top of the electrical connection. It is possible to improve the workability and reliability of the tightening work by making it possible to An object of the present invention is to provide electrical connectors for

[0006]

【Example】

The present invention will be explained in detail below based on the embodiments shown in FIGS. 2 to 4.

[0007] In FIGS. 2 and 3, reference numeral 11 denotes an electrical connector for the battery. The fitting 11 includes a base 12 made of a strip-shaped metal piece, and a base 12 that is made of a strip-shaped metal piece. It extends from one end in a direction parallel to the plane of the base 12 and is folded back into a substantially U-shaped plane. from the other end of the base 12 in a direction parallel to the plane of the base 12. A wire connecting portion 14 and an auxiliary terminal connecting piece 15 are integrally formed. In addition, a screw hole 16 is formed in the center of the base 12 and extends vertically. A rectangle having a long side parallel to the plane of the base 12 is formed on the opposite side of the post pressure contact part 13. Through holes 17 are formed respectively. 18 is a band-shaped piece with a horizontal U-shape on the side. This contact piece 18 is bent in the opposite direction, and the opposite side of the contact piece 18 has a bolt insertion hole 1. 9 is drilled. Further, on both sides of the bent portion of the contact piece 18, the through hole 1 is provided. A guide protrusion 20 that is loosely fitted into the inside of the guide protrusion 7 is provided in a protruding manner. 21 is screwed into the screw hole 16. 22 is an electric wire connected to the electric wire connection part 14, and 23 is a battery. Show the post.

[0008] Next, to describe its function, the pair of guide protrusions of the contact piece 18, which is the above-mentioned member, The bolt 20 is loosely fitted into the through hole 17, and then the bolt insertion hole 1 of the contact piece 18 is inserted. By screwing the bolt 21 inserted into the hole 9 into the screw hole 16, the electrical connection tool 11 is removed. The assembly is completed. Therefore, as shown in FIG. After inserting the battery post 23 into the The piece 18 is deformed into a flat shape as shown by the chain line, and as a result, the bent part of the contact piece 18 is shaped like a post. The post 23 that extends in the direction of the pressure contact portion 13 is pressed by the post pressure contact portion 13, and the The electrical connection between the teripost 23 and the electrical connector 11 is maintained.

[0009] Therefore, according to the electrical connector of this embodiment, this electrical connector 11 can be connected to the battery port. The connection work for connecting to the electric connector 11 is performed in the vertical axis direction (vertical direction) of the electrical connector 11. This can be done with the tightening force of the bolt 21, which has its center axis in the horizontal direction. For tightening screws located in It is something that gives you practical experience.

[Effect of the idea]

As described above, in the present invention, one end of the base 12 is the wire connection part 14, and the other end is a flat surface. A U-shaped post pressure contact part 13 is provided, and a vertical screw hole 16 is provided in the center of the base. is formed on the opposite wall of the post pressure contact part 13 in a direction parallel to the plane direction of the base part 12. A member formed with a rectangular through hole 17 having long sides, and a member formed in a horizontal U-shape on the side. A bolt insertion hole 19 is formed in each of the opposing pieces, and furthermore, both of the U-shaped bent portions are provided with bolt insertion holes 19. a contact piece 18 having a guide protrusion 20 formed on its side edge to be loosely fitted into the through hole 17; A bolt 21 is screwed into the screw hole 16 to fasten the contact piece 18 to the member. According to this, the electrical connector for a battery is The screw shaft of the tightening screw for tightening to the battery post is located in the vertical direction. The tightening screws mentioned above can be tightened because they can be tightened on the top of the electrical connection. The effect is that the ease of tightening work and the reliability of tightening work are greatly improved. .
