Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to an electrical connector for a battery for connection to a post of the battery.

[Background of the idea]

Conventionally, the fourth type of electrical connector was used for connecting batteries and in-vehicle electrical components in automobiles, etc.
What is proposed is shown in the figure. In the same figure,
Reference numeral 1 designates a connection terminal that is fastened to a post 2 of a battery (not shown), which includes a crimping part 3 bent into a substantially circular shape so as to be crimped onto the circumferential surface of the post 2, and a predetermined crimping part 3 attached to the crimping part 3. It consists of a fastening part 6 that is tightened with a bolt 4 and a nut 5 to provide a coupling friction force. A cable 7 for distributing power to electrical equipment (not shown) is connected to the fastening portion 6. Further, 8 is an auxiliary terminal for directly distributing power from the battery to other electrical components, which is fastened together with the connecting terminal 1 with a bolt 4 and a nut 5, and a connector 10 with a cable 9 connected to this auxiliary terminal 8 is fitted. I'm starting to be able to do it.

However, in the case of such a conventional electrical connector for a battery, after the connecting terminal 1 is placed on the post 2 of the battery, the connecting terminal 1 is connected to the bolt 4,
Since the structure is tightened by nuts 5, it takes time and effort to tighten the bolts 4 and nuts 5.
The workability of the connection is poor, and the tightening force of the bolts 4 and nuts 5 varies, sometimes causing deformation of the post 2 or the connecting terminal 1 due to excessive tightening force, or insufficient tightening force. According to
There were problems such as failure to maintain an effective connection and poor contact.

[Purpose of invention]

The present invention has been developed in view of these conventional problems, and includes a pair of terminal pieces that can hold a battery post in its mouth, and a tightening lever that can move the pair of terminal pieces toward or away from each other. By one-touch operation of the tightening lever together with the terminal cover, the pair of terminal pieces can be fastened to the battery post and the terminal cover can be attached at the same time. It is an object of the present invention to provide an electrical connector for a battery that can reliably attach a terminal cover with one touch.

[Example of idea]

The present invention will be explained in detail below based on the embodiments shown in FIGS. 1 to 3.

Reference numeral 11 denotes an electrical connector for a battery, and this electrical connector 11 includes a first terminal piece 13 having a substantially U-shaped plane and a substantially semicircular arc portion 12, and a substantially semicircular arc portion 12. It has a second terminal piece 15 having a portion 14, and the first and second terminal pieces 13 and 15,
Battery post 2 installed on battery 16
It is joined by holding the periphery. A long hole 17 extending in the horizontal direction is bored at both ends of the first terminal piece 13, and a support shaft 18 penetrating through both of these long holes 17 and loosely fitted is connected to the second terminal piece 13. It is inserted into a shaft hole 19 that is integrally formed on the back surface of the terminal piece 13. One end of each link 20 is pivotally attached to both ends of the support shaft 18, and a connecting rod 21 is suspended and held at the other end of both links 20. Reference numeral 22 denotes an electric wire connecting portion formed integrally with the second terminal piece 15, and an electric wire 23 is connected to this electric wire connecting portion 22. Reference numeral 24 denotes a cover made of hard resin and placed over the electrical connector 11 having the above-mentioned structure. Both ends of the connecting rod 21 are lockingly connected to the inside.

The structure of the present embodiment has been described above. Next, to describe its operation, the link 20 connected to the cover 24 via the connecting rod 21 is connected to the cover 24.
4, the support shaft 18 can be moved inside the elongated hole 17 to the right in FIG. 1, as shown in FIG. The terminal piece 15 is attached to its support shaft 18.
As a result, the clamping force on the battery post 2 by the first terminal piece 13 and the second terminal piece 15 is released, and the electrical connector 11 is removed from the battery post 2. be able to. On the contrary, after positioning the first terminal piece 13 and the second terminal piece 15 on the outer surface of the battery post 2, the link 20 is pushed down together with the cover 24 in the state shown in FIG. The shaft 18 is
As a result, the second terminal piece 15 moves in the direction of the arc portion 12 of the first terminal piece 13, and the battery post 2 is moved between the first terminal piece 12 and the second terminal piece. 15 to connect the electrical connector 11 to the battery post (see FIG. 3).

Therefore, according to the electrical connector of this embodiment, it is possible to connect the electrical connector to the battery post 2 by a simple operation of vertically rotating the link 20 together with the cover 24, that is, by a one-touch operation. On the contrary, since it can be removed, the workability of attaching and detaching the electrical connector is improved. Furthermore, according to this embodiment, the cover 24
1, and the link 20 of the electrical connector 11 can be operated together with the cover 24. Therefore, the electrical connector 11 can be attached and detached with one touch without removing the cover 24, which improves work efficiency. This has the effect of improving

[Summary of the idea]

As described above, in the present invention, the second terminal piece 15, which has a semicircular arc cross section, is placed between the two terminal pieces 13, 15 in the width of the first terminal piece 13, which has a substantially U-shaped cross section. Elongated holes 1 are arranged to form a substantially circular shape and extend along both ends of the first terminal piece 13.
7, both ends of a support shaft 18 supported by the second terminal piece 15 are loosely fitted into the elongated hole 17, and one end of the link 20 is pivotally supported on both ends of the support shaft 18. The other end is pivotally supported on a cover 24 that covers both the terminal pieces 13 and 15, and when the cover 24 is pressed, both the terminal pieces 13 and 15 come close to each other and the battery post 2 is held between them. This is an electrical connection tool for batteries, which is characterized by:

[Effect of idea]

Therefore, according to the battery electrical connector of this invention, this electrical connector can be connected to the battery post 2 by a simple operation of vertically rotating the link 20 together with the cover 24, that is, by a one-touch operation. , and conversely, it can be detached, which has the effect of improving the workability of attaching and detaching the electrical connector. Further, according to the present invention, the cover 24 is
Since it is integrally coupled with the electrical connector 11 and the link 20 of the electrical connector 11 can be operated together with its cover 24, the electrical connector 11 can be attached and detached with one touch without removing the cover 24. This has the effect of improving workability.
