Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a cable connecting device for a battery jump start and an earth terminal,

More particularly, the present invention relates to a cable connecting apparatus in which a terminal portion for use in a welding earth terminal or a battery jump start is separated from a handle portion and at the same time a portion where a cable is drawn is separated from a handle will be.

Generally, the vehicle starts by using the starting motor by the power supplied from the battery.

However, when the battery wiring wire is peeled off, the contact is bad, or the driver's carelessness (such as when the headlight, fog lamp, interior lamp is turned on for a long time or the power supply to the black box is turned off while the ignition is turned off) A situation occurs in which the engine can not be started because there is not a minimum amount of electric power that can be supplied to the starter motor to start the engine.

In such a situation, a normal battery is used to start the vehicle in which the battery is discharged, or the battery is charged with the assistance of another vehicle driver. In order to start the vehicle using the battery of another vehicle, the hood of each vehicle is opened, and then the battery of the other vehicle and the battery of the other vehicle are electrically connected to each other by using a Jump Starter (Booster) The battery can be charged to start the engine.

X1 and the second region X2 are formed in the middle of the third region X3 so as to be spaced apart as described above.

3, the terminal portion 170 is formed in the first region X1 of the main body 110 so that the terminal portion 170 is firmly coupled and fixed without a separate coupling means such as a bolt, A terminal fitting slot 113 is formed so as to be able to fit the terminal fitting 170 in a corresponding manner in accordance with the shape of the terminal fitting portion 170. The main body 110 is provided with a cable penetration part 115 through which a cable 180 can pass and which has a cable penetration hole 115a protruding outward so that the cable 180 can penetrate through the center thereof, have. The cable 180 does not pass through the second region X2 and the third region X3 which will be described later.

The terminal portion 170 is preferably made of a material having excellent electrical conductivity including copper, and has a known tooth or sawtooth-shaped end portion and is bent in a 'C' shape in cross section. The terminal portion 170 has a "U" -shaped cross-section having a tooth-like end to firmly engage with the terminal of the battery and is firmly supported by the terminal-portion-engaging slot 113 of the main body 110 A terminal portion main body 173 and a cable clad refusal portion 175a extending from the terminal portion main body 173 and covering the cable 180 to be electrically connected to the cable 180. The cable clad refusal portion 175a is firmly clamped or supported It is preferable that the cable clamp portion 175 is provided.

It is preferable that the cable clamp portion 175 is embedded in the end face of the recessed terminal portion engaging slot 113 of the main body 110 and is not exposed to the outside, thereby preventing unnecessary contact to improve stability.

The second area X2 of the main body 110 is formed with a handle 150 that can be held by the user. The handle 150 is provided with an oval convex shape A grip groove 153 including a groove may be formed.

The second area X2 may be provided with a pivoting elastic coupling part 119 so that the pivoting elastic part 130 can be coupled. The pivoting elastic coupling portion 119 may be provided in a shape slightly recessed from the plate surface corresponding to the shape of the pivoting elastic body 133. [

The pivotable elastic part 130 is coupled to the main body 110 so that the user grips the grip part 150 and provides the elastic force to the main body 110 so that the terminal part 170 can rotate between the clamping position and the separation position . The pivoting elastic part 130 includes a pivoting elastic body 133 provided in a pair and coupled to the pivoting elastic coupling part 119 of each main body 110 and a pivot pin hole The main body 110 is elastically deformed into a separated position where the terminal portions 170 of the main body 110 are not engaged with the battery and the terminal portions 170 are engaged with each other, It is preferable to have an elastic member 135 which is supported on each main body 110 or the pivoting elastic body 133 to provide a pressing force and includes a known spring.

When the user grips the handle 150, the terminal portions 170 are separated from each other, and a terminal (not shown) of the battery is interposed therebetween. When the user holds the handle 150, the elastic force of the elastic member 135 can maintain the clamping position where the terminal 170 is holding the battery terminal. After the use of the cable connector 100 is completed, the user presses the handle 150 to disengage the terminal portion 170 from the battery terminal. When the pressing force of the handle 150 is released, And the user can store the cable connecting device 100 of the present invention at a predetermined position by arranging the cable 180 and the main body 110 and use the cable connecting device 100 when necessary.

An example of the use of the cable connection apparatus 100 will be described with reference to FIG.

First, the user is careful to electrically connect the pair of cable connecting devices 100 to the positive and negative poles of the battery. Then, after the user holds the handle 150 and presses the same to open the terminal portions 170 apart, the user places the terminals of the battery in the spaces between the terminal portions 170, The terminal portion 170 firmly couples the battery terminal (not shown) by the elastic force of the elastic member 135 of the pivotable elastic portion 130 and the terminal portion 170 at both ends of the cable ) Can be made. 5A, in the cable connecting apparatus 100 according to the present invention, the first area X1 and the second area X2 are not in the same plane but spaced apart from each other (in FIG. 5A, Referring to FIG. 5B, it can be seen that the present invention can be used without any interference with other configurations around the battery, so that it is very convenient to use according to the present invention.

The first region X1 in which the cable 180, the cable clamp portion 175 and the cable penetration portion 115 are disposed is divided into the second region X2 and the third region X1, The user is particularly distanced from the cable 180, the cable clamp 175 and the terminal 170 so that the user is somewhat careless or the cable clamp 175 is not in contact with the user's hand, It is possible to prevent electrical hazards such as peeling of the coating of the substrate, and the stability can be greatly enhanced. Here, it is a matter of course that the outer side of the cable 180 is wrapped with a non-conductive material including rubber, like the known cable.

Since the cable 180 used for the present invention is not always electrically connected and is not required to be highly precise or high electrical efficiency by being temporarily used in case of battery discharge or the like, It is preferable to include a copper-clad aluminum wire (CCA). Conductivity or conductivity of aluminum is 61% of copper, but price is very low in terms of price and conductivity compared to conductivity. Therefore, when copper-coated aluminum wire is used, it is more economical than copper have.

5A and 5B, the cable connection apparatus 100 can be easily connected even when the parts to be welded are electrically connected in the case of welding as described above. Of course.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the invention. will be.
