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 to connect 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, reference numeral 8 denotes an auxiliary terminal for distributing power directly from the battery to other electrical components, which is tightened together with the connecting terminal 1 by bolts 4 and nuts 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 was developed by focusing on such conventional problems, and includes a crimping part curved into a substantially circular shape to be joined to the circumferential surface of the battery post, and an eccentric cam for pressing the crimping part to the battery post. To provide an electrical connection tool for a battery, which can securely connect the connecting tool to the battery post with a single touch by tightening the crimping part to the battery post by one-touch operation of the eccentric cam. The purpose is to

[Summary of the idea]

In order to achieve the above object, the electrical connector for a battery according to the present invention is provided by folding the other end of the connecting piece 15 to which the electric wire 18 is connected at one end into a C-shape, and connecting the crimp part 13 into which the battery post 12 is fitted. A folded piece 14 extending substantially parallel to the connecting piece 15 from the tip of the crimp portion 13 is provided, and is positioned between the folded piece 14 and the connecting piece 15 to pivotally support the eccentric cam 17. The cam 17 has a shape in which its small diameter portion 17b faces the battery post 12 in the upright state, and its large diameter portion 17a faces the battery post 12 in the collapsed state, and the eccentric cam 17 is rotated to It is characterized in that at least the crimp part 13 is connected to the crimping part 13.

[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 a connection terminal that is fastened to the battery post 12, and this connection terminal 11 has a crimping part 13 which is curved in a substantially C-shape in plan view, and a pair of crimping parts 13 extending parallel to each other from both ends of the crimping part 13. Folding piece 14,1
5, a support shaft 16 extending over both folded pieces 14 and 15, and an eccentric cam 17 pivotally attached to the support shaft. The eccentric cam 17
has a shape in which its small diameter portion 17b faces the battery post 12 in an upright state, and its large diameter portion 17a faces the battery post in its collapsed state. An electric wire 18 is connected to one of the folded pieces 15, and a cam lever 19 for rotating the eccentric cam is integrally formed with the eccentric cam 17.

The above is the structure of this embodiment. Next, to describe its operation, as shown in FIGS. 1 and 2, when the cam lever 19 of the eccentric cam 17 is in the upright position, Since the crimping portion 13 of the connecting terminal 11 is shaped to face the battery post, the diameter of the crimping portion 13 of the connecting terminal 11 is large.
Therefore, the battery post can be easily inserted into the crimp portion 13. In this way, the crimp part 1
3 into the battery post 12, by tilting the cam lever 19 as shown in FIG.
This reaction force presses the inner surface of the crimp portion 13 of the connection terminal 11 against the circumferential surface of the battery post 12, and as a result, the connection terminal 11 can secure electrical connection to the battery post 12. If the cam lever 19 is raised from this state (Fig. 3),
Since the clamping force of the eccentric cam 17 on the battery post 12 is released, the connection terminal 11 can be removed with one touch.
can be removed from the battery post 12.

Therefore, according to the battery electrical connection device of this embodiment, the connection terminal 11 can be reliably connected to or disconnected from the battery post 12 by a one-touch operation of tilting the cam lever 19. This has the effect that the work of connecting and separating the connection terminal 11 can be performed extremely easily.

[Effect of idea]

Therefore, according to the electrical connector for a battery of this invention, the connection terminal 11 can be reliably connected to or disconnected from the battery post 12 by a one-touch operation of rotating the eccentric cam. This has the effect of making it extremely easy to connect and separate the connection terminal 11, and the clamping force of the crimping part 13 when connecting the battery post 12 and the connection terminal 11 is sufficient for electrical connection due to the shape of the eccentric cam. Furthermore, the main parts are the crimping part 13, the eccentric cam 17, etc., so the number of parts is small, and the structure is simple and easy to manufacture.
