Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an electrical connection clip used for charging and discharging batteries, storage batteries, etc., and for connecting with input/output terminals of electronic devices.

BACKGROUND TECHNOLOGY Conventionally, a cord used for extracting power externally or temporarily from a car battery has been called a booster cord, and as shown in FIG. 4, the handles of both contact pieces 1 and 2 are made of synthetic resin such as plastic. 1b and 2b to insulate and connect the positive (+) and negative (-) clips of the uninsulated metal fittings 1a and 2a to both terminals of the battery, respectively, and connect the metal fittings 1a and 2b to both terminals of the battery. , 2a, connection cords 7 and 8 are pulled out through solder or the like, and the output is taken out. However, there is a high risk that the metal fittings of both clip connection pieces will come into contact with each other and cause unnecessary over-discharge, which will damage the circuit and affect the battery life. It was also troublesome because of the pinching.

Problems to be Solved by the Invention In consideration of these points, we attempted to cover most of the metal parts of both clip contact pieces with insulation, and to connect both clip contact pieces together using an insulator. However, it was rather difficult to handle.

Means for Solving the Problems For this reason, the inventor of the present invention has conducted further trial production and experiments, and as a result, has provided a new electrical contact clip. That is, the present invention includes two contact pieces 1 and 2 that exist independently of each other, and inner and outer cylinders 4 and 5 that extend from each contact piece 1 and 2 and are slidably fitted into each other.
Alternatively, by providing an elastic spring 3 provided between the square body and the insulated contact pieces 1 and 2 in order to make at least one of them movable, both the contact pieces 1,
2 and maintaining at least a predetermined insulation interval to enable alternative connection to both terminals of a storage battery or the like.

Function With this configuration, by selecting the shape of the clip contact piece according to the intended connection terminal structure, a smooth electrical connection can be made. There was no short circuit between the two, so damage to the circuit and impact on battery life are no longer of concern.

Embodiment Figures 1, 2, and 3 are side sectional views of the main parts of embodiments of the electrical connection clip according to the present invention with different shapes of clip contact pieces, and the purpose, function, and operation are the same. be.

First, in FIG. 1, both contact pieces 1 and 2 have a clothespin shape as in the conventional case, and when connected to a target terminal, they become a positive (+) contact piece and a negative (-) contact piece. A telescopic spring 3 is sandwiched between the contact pieces 1 and 2 via an insulating collar 1c, and is wound around cylinders 4 and 5 that can be extended from the contact pieces 1 and 2. The inner cylindrical body 4 is extended from the insulating collar 1c of the contact piece 1, and is fitted inside the outer cylindrical body 5 so that it can slide.
Incidentally, if necessary, grooves may be provided in a portion of the cylinders 4 and 5 to prevent rotation between the cylinders 4 and 5, and the cylinders 4 and 5 may be fitted together. In use, although not shown, the spring 3 should be expanded and contracted according to the spacing between the connection terminals so that one contact piece 1 is connected to one terminal and the other contact piece 2 is connected to the other terminal. , 8, a desired output can be obtained.

Figures 2 and 3 show contact pieces 1 and 2 with different shapes, respectively. In Figure 2, one contact piece 1 is hook-shaped, and the other contact piece 2 is an L-shaped metal fitting. An insulating collar 6 is provided on one side of the contact for insulation between the pieces 1 and 2. In addition, in FIG. 3, the elastic spring 3 is
However, other operations are carried out within the first
This is the same as in the case of FIG. In addition, the contact piece can have various shapes depending on the shape of the contact terminal portion. Furthermore, the same effect can be achieved even if the cylinders 4 and 5 are square bodies.

Effects of the invention With this configuration, the present invention enables alternative connection to both terminals of a storage battery, etc. by maintaining a predetermined insulation interval between both contact pieces. Select the shape of the clip connection piece,
Furthermore, by using a telescoping mechanism using a telescoping spring between both contact pieces, a smoother electrical connection is possible than in the past.

[Brief explanation of the drawing]
