Description

Connector structure of battery terminal for vehicle

The present invention relates to a battery terminal fastening structure for an automobile, and more particularly, to provide an improved battery terminal fastening structure to facilitate the connection of the battery terminal and the cable without using a separate tool.

The battery of the vehicle is installed at one side of the engine room or the trunk room and charged from the generator, and supplies the power required for the operation of various electrical equipment such as the initial power required for starting the engine or the headlight of the vehicle.

The battery is provided with a positive terminal and a negative terminal to be connected to a cable. In the related art, as illustrated in FIGS. 1 and 2, terminals 2 provided on the upper surface of the battery 1 protrude upward.

The terminal 2 has a larger diameter at the lower side than the upper side, such as a truncated cone, so as to provide ease of coupling, and increases the size of the positive terminal rather than the negative terminal to eliminate the possibility of incorrect coupling. .

The cable terminal 4 provided at the end of the cable 3 to be connected to the terminal 2 has a receiving groove 5 for accommodating the terminal 2 of the battery 1 and one side is easy to insert Place the opening (6) to provide.

The opening 6 is formed to be fastened in a rigid state by using the bolt 8 and the nut 9 to form a fastening bracket (7).

In the prior art as described above, since a separate tool must be used to disassemble and assemble the cable terminal, workability is deteriorated. When the tool is connected to the vehicle during disassembly and assembly, the negative terminal of the battery is connected to the vehicle body. There is a risk of short circuit because it is grounded.

In particular, since the terminal of the battery protrudes upward, there is no easy transportation and storage, and there are various problems such as a short circuit when the terminal and the conductor are inadvertently contacted during storage and transportation.

Therefore, the present invention is designed to solve the above problems, and it is possible to fasten the battery terminal and the cable terminal without a separate tool, and improve the configuration of the battery terminal to solve the short circuit problem that may be caused in the process of storage and transportation. It aims to contribute to overall assembly and quality improvement by solving.

The battery 30 is mounted on one side of the engine room or the trunk room of the vehicle and charged from the generator, and supplies the power required for the operation of various electrical equipment such as initial power required for starting the engine or headlights of the vehicle.

In the present invention, the terminal 31 of the battery 30 and the terminal 33 of the cable 32 connected thereto are improved to provide ease of fastening work in a one-touch type, as well as short circuits that may be caused in handling. It is characteristic to be able to exclude concerns.

The terminal 31 formed on the top surface 35 of the battery 30 is formed to enter the inside of the battery 20, and the cable 32 terminal 33 coupled thereto is formed to protrude.

The battery 30 terminal 31 forms an insertion portion 36 tapered in a vertical light narrowing shape, and the terminal 33 of the cable 32 is positioned below the head 37 made of an insulator. The protrusion 38 of the same shape as the terminal 31 is formed.

An insertion preventing means 40 is formed on the insertion part 36 of the battery 31 terminal 31 and the protrusion part 38 of the cable 32 terminal 33 to prevent the separation after the mutual coupling.

The separation preventing means 40 is a key 41 formed to protrude from the bottom of the protrusion 38 of the cable 32 terminal 33 and a key groove formed in the insertion portion 36 of the terminal 31 of the battery 30. It consists of 42.

The key groove 42 formed in the insertion portion 36 is formed only in one direction from the top surface 45 to the bottom surface 46 of the insertion groove 36, and the key of the protrusion 38 on the bottom surface 46. Further, the idle space 47 in the range of 90 ° is further formed so that 41 can be rotated and locked.

The height H of the revolving space 47 is lowered from the starting point H1 to the end point H2 so that the key 41 becomes easily coupled to the end point H2 where the rotation ends. It is desirable not to.

Looking at the fastening process of the terminal 31 and the cable 32 terminal 33 of the battery 30 of the present invention as described above.

First, hold the head 37 of the cable (32) terminal 31 so that the protrusion 38 protruding downward thereof is directed downward, and then inserted into the insertion portion 36 of the terminal (31) of the battery (30). .

At this time, the key 41 of the protruding portion 38 is matched with the key groove 42 formed in the insertion portion 36 so as to be naturally inserted.

When the projection part 38 is inserted into the insertion part 36 and the key 41 is inserted to the bottom surface 46 of the insertion part 36, the head 37 of the terminal 33 of the cable 32 is grasped by the 90 ° direction. Rotate

Then, the key 41 of the protrusion 38 can rotate through the idle space 47 formed in the bottom surface 46 and move from the start point H1 of the idle space 47 to the end point H2. When the cable 32 is completely fixed, the terminal 33 is not detached.

When the key 41 of the cable 33 terminal 33 moves to the end point H2 of the process space 47, the height of the end point H2 is lower than the height of the start point H1 of the process space 47. As a result, the key 41 is naturally shaped to be forcibly coupled to the revolving space 47 so that the key 41 is not easily separated (rotated in the reverse direction).

In order to release the fastened state as described above, hold the head 37 of the cable 33 terminal 33 and rotate the key 41 to come to the starting point H1 of the idle space 47. After making the key groove 42 coincide with the cable 33, the terminal 33 is separated.

The present invention as described above can be fastened and disassembled the battery 30 terminal 31 and the cable 32 terminal 33 in a one-touch type without a separate tool to facilitate assembly, the battery 30 terminal ( Since 31) is impregnated, it is possible to exclude a short circuit that may occur during storage or transportation of the battery 30.

This invention can be connected between the battery terminal and the cable terminal without a separate tool, and can improve the configuration of the battery terminal to solve the short circuit problem that can occur during the storage and transport process, and contribute to the overall assembly and quality improvement. Many effects can be achieved.
