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 invention]

In automobiles, etc., conventionally, the fifth
The one shown in the figure has been proposed (for example,
No. 106364). In the figure, reference numeral 1 denotes a connection terminal that is fastened to a post 2 of a battery (not shown), and a crimping part 3 that is bent into a substantially circular shape so as to be crimped onto the circumferential surface of the post 2; It consists of a fastening part 6 that is tightened with a bolt 4 and a nut 5 so as to apply a predetermined coupling friction force to the bolt 4 and the nut 5. A cable 7 for distributing power to electrical equipment (not shown) is connected to the fastening portion 6. In addition, 8 is an auxiliary terminal for distributing power directly from the battery to other electrical components, with bolt 4 and nut 5.
The connector 10 with the cable 9 connected to the auxiliary terminal 8 can be fitted to the connecting terminal 1.

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 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. To provide an electrical connection tool for a battery, in which the pair of terminal pieces can be fastened to the battery post by one-touch operation of the tightening lever, and the connection to the battery post can be reliably performed with one-touch operation. The purpose is to

[Example of idea]

The present invention will be explained in detail below based on the embodiments shown in FIGS. 1 to 4.

The other end of the connecting piece 11, to which an electric wire (not shown) is connected to the electric wire connecting part 11d provided at one end, is folded back to the opposite side almost parallel to the folded piece 11.
1a, and a substantially circular holding portion 11b for holding the battery post 12 therebetween is provided at the center of each of the pieces 11, 11a.

Both pieces 1 are attached to the other ends of both pieces 11 and 11a.
A base end portion of the crimp lever 13 is pivotally supported by a bolt 14 sandwiched between the crimp lever 1 and 11a. A crimp portion 13a having a U-shaped cross section is provided at the free end of the lever 13.
connects the free end of the lever 13 to the two pieces 11, 11
When it is laid down in position a, it is fitted into one end of each of the pieces 11, 11a from the outside while being biased so that the pieces 11, 11a approach each other. Further, a claw 13b is formed inside the crimp portion 13a, and this claw 13b is connected to the two pieces 11, 11.
It is adapted to be locked in a locking hole 11e provided at one end of each of the parts a.

Therefore, when the claw 13b is locked in the locking hole 11e, the crimp portion 13a of the lever 13 is urged to approach one end of each of the pieces 11, 11a while pushing the outside thereof. It is retained in place. As a result, both the holding portions 11b
The battery post 12 is held in place by the two.

15 is a lever 13 and both pieces 11, 11;
A shows a resin terminal cover that covers them from above, and this terminal cover 15 is
It consists of a fixed part 15a and a movable part 15c that are locked and fixed to the wire connection part 11d of the connection piece 11, and these parts 15a and 15c are connected via a thin hinge 15b, so that the movable part 15c can be undulated. I'm starting to do that. 20 is the terminal cover 15 that has fallen down.
This is an engaging portion that engages the two pieces 11, 11a. 11f is a subterminal.

The configuration of this embodiment has been described above, and its operation will be explained next. As shown in FIGS. 1 and 2, with the lever 13 upright, both pieces 11 and 1
The pair of clamping parts 11b of 1a hold the battery post 1.
2, and then remove the movable part 1 of the terminal cover 15.
5c in the arrow direction A in FIG. 2, and at the same time, the lever 13 is lowered. The crimp part 1
3a pinches one end of both pieces 11, 11a (see FIG. 3), and as a result, one end of both pieces 11, 11a is pressed and urged in a direction toward each other by both crimping parts 13a. The holding part 11b is
Both pieces 1 are pressed against the battery post 12, and as a result, both pieces 1
1 and 11a are electrically connected to the battery post 12.

Conversely, to disconnect the connection, raise the movable part of the terminal cover 15 and then raise the lever 13 using the bolt 14 as a fulcrum.
1 and 11a is released, the clamping portion 11b is released from clamping the battery post 12, and as a result, both pieces 11 and 11a can be removed from the battery post 12.

Therefore, according to the battery electrical connector of this embodiment, the electrical connector can be connected to the battery post 12 and conversely disconnected by a simple operation of raising and lowering the lever 13, that is, by a one-touch operation. This has the effect of improving the workability of contact and separation. Furthermore, according to this embodiment,
Since the lever 13 can be lowered by lowering the cover 15, the electrical connector can be inserted and installed with one touch, and the work efficiency is improved. In addition, the cover 15 is attached to the hinge 1
It is formed of a fixed part 15a and a movable part 15c, which are connected by a fixed part 15a and a movable part 15c, and the movable part 15c is provided so that it can be raised and lowered. By raising the movable part 15c, the lever 13 is exposed. There is also the effect that operations such as checking the connection state between the electrical connector and the battery post 12 and making a temporary test connection to the battery post can be performed easily and reliably.
