Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to an automobile battery terminal connection structure. Background Art

[0002] Car batteries, also known as storage batteries, convert chemical energy into electrical energy through chemical reactions, providing starting power for the car and meeting other power needs; car batteries are equipped with positive and negative terminals that are connected to the positive and negative poles of the battery respectively. The positive and negative terminals are generally connected to the cables using battery clamps to fix the connection between the cables and the battery poles to ensure stable transmission of current.

[0003] When a battery clamp is used to clamp the battery terminal, since the terminal is mostly in the shape of a vertical cylinder, when the car starts and vibrates during driving, the battery clamp is likely to slide along the vertical side wall of the terminal, causing the terminal to become loose due to vibration. The loose state may cause circuit interruption or poor contact. At the same time, when the battery clamp is used to connect the terminal, the cable extending from the end of the battery clamp is likely to be scattered around the car battery, making it inconvenient to arrange the cables neatly. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a vehicle battery terminal connection structure to solve the problem that when the battery clamp clamps the battery terminal, the battery clamp easily slides and falls off along the vertical side wall of the terminal, which easily leads to circuit interruption or poor contact.

[0005] In order to achieve the above-mentioned purpose, the basic scheme of the utility model is as follows: a car battery terminal connection structure, comprising:

[0006] An elastic conductive ring, the conductive ring is in an incomplete ring shape;

[0007] An adjusting connection part, wherein the adjusting connection part is used to adjust the distance between the two ends of the conductive ring, and the inner wall of the conductive ring can be fitted with the side wall of the terminal;

[0008] A plurality of connection blocks are connected by rotating in sequence to form a connection belt. A conductive block fixedly connected to the outer wall of the conductive ring is fixedly arranged in the connection block at the end. The conductive block is electrically connected to the cable, and the cable is detachably connected to the plurality of connection blocks.

[0009] The technical principle of the utility model is: when installing the automobile battery terminal connection structure to the terminal, firstly control the outline of the conductive ring to be larger than the cross-sectional outline of the terminal by adjusting the connection part, install the conductive ring to the terminal, and then reduce the distance at both ends of the conductive ring by adjusting the connection part, so that the conductive ring can be deformed and clamped to the terminal; when the automobile vibrates during driving, the conductive ring and the terminal are in surface contact, and the conductive ring can be tightly installed on the terminal under the action of adjusting the connection part, which can reduce the risk of loosening and falling off of the conductive ring and the terminal.

[0010] At the same time, the cables can be installed in a limited position by several connecting blocks, so that the excess cables can be limited by the connecting belts, and it is convenient for the ends of the cables to be tightly electrically connected to the conductive blocks. The connecting belts can make the excess length of cables more tidy, so that other structures can be easily installed and arranged in other spaces in the car.

[0011] Furthermore, a socket for inserting a cable is provided on the connection block at the end of the connection belt, and one end of the conductive block electrically connected to the cable is located in the socket.

[0012] Through the above arrangement, the connecting block can protect the conducting block, and the arrangement of the jack can make the installation of the cable end more stable, and the electrical connection between the cable end and the conducting block more stable.

[0013] Furthermore, the connection block is provided with a serial connection hole for the cables to pass through.

[0014] Through the above arrangement, the ends of the cables can pass through the serial holes on the connecting block in sequence, and the serial holes limit the middle part of the cables, which can improve the stability of the cable limit.

[0015] Further, the adjusting connection part comprises:

[0016] A first insulating block, the first insulating block is fixedly mounted on one end of the conductive ring;

[0017] The second insulating block is fixedly mounted on the other end of the conductive ring.

[0018] Bolts and nuts, the bolts pass through the first insulating block and the second insulating block and are threadedly connected with the nuts.

[0019] Through the above arrangement, when the conductive ring is fixed to the terminal, the nut on the bolt is tightened, the first insulating block and the second insulating block are brought close to each other, and the first insulating block and the second insulating block drive the two ends of the conductive ring to approach each other, otherwise the conductive ring is loosened and removed, so that the installation, fixing and disassembly of the conductive ring are convenient and fast, and the installation is stable.

[0020] Furthermore, a rotating connection portion is provided between two adjacent connection blocks, and the rotating connection portion includes:

[0021] A connecting piece, the connecting piece is located between two adjacent connecting blocks, and grooves are provided on both sides of the connecting block close to the connecting piece for the edge of the connecting piece to be embedded;

[0022] Two rotating shafts are located on both sides of the connecting piece close to the connecting block. The rotating shafts pass through the edges of the connecting piece and the connecting block, and the axes of the rotating shafts are perpendicular to the opening direction of the groove. The rotating shafts are rotatably connected to the connecting piece or the connecting block.

[0023] Through the above arrangement, in the process of adjusting the length of the connecting belt, the connecting belt can be quickly extended or shortened by disassembling the rotating shaft at the connecting piece and the connecting block, so that the length of the connecting belt can adapt to the length required for the cable to be fixed.

[0024] Furthermore, the edge of the connecting piece is in an arc shape that fits the inner wall of the groove.

[0025] The above arrangement facilitates the connection between the connecting piece and the connecting block to rotate, thereby facilitating relative rotation between the two connecting blocks and the connecting piece at the local part, so that the connecting belt can better fit the side wall of the car battery.

[0026] Furthermore, the serial connection hole is cylindrical.

[0027] Through the above arrangement, when the outer wall of the cable contacts the inner wall of the serial connection hole, the cable contacts the surface of the serial connection hole, so that the serial connection hole can fully fit and limit the cable.

[0028] Furthermore, the serial connection hole is located at the middle of the connection block.

[0029] Through the above arrangement, the connection points between the cables and the connection blocks are all located in the middle of the connection blocks, so that the cables after the connection are more neatly confined on the connection belt. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0035] This embodiment is basically Figure 1 , Figure 2 and Figure 3 As shown, the embodiment of the utility model proposes a car battery terminal connection structure, including an elastic conductive ring 10, an adjustable connecting part and a plurality of spliced ​​connecting blocks 201, wherein the connecting blocks 201 are all made of rubber, wherein the conductive ring 10 is an incomplete ring shape, and the conductive ring 10 is made of copper material, so that the conductive ring 10 has both conductivity and elasticity.

[0036] like Figure 2 As shown, the adjustment connection part is used to adjust the distance at both ends of the conductive ring 10, and the inner wall of the conductive ring 10 can fit with the side wall of the terminal 2. At the same time, the adjustment connection part includes a first insulating block 101, a second insulating block 102, a bolt 103 and a nut 104. The first insulating block 101 is fixedly installed on one end of the upper side of the conductive ring 10; the second insulating block 102 is fixedly installed on one end of the lower side of the conductive ring 10, and the bolt 103 passes through the first insulating block 101 and the second insulating block 102 and is threadedly connected with the nut 104.

[0037] like Figure 2 and Figure 3 As shown, a plurality of connection blocks 201 are rotatably connected in sequence to form a connection belt 20, and a rotatable connection portion is provided between two adjacent connection blocks 201; a conductive block 203 fixedly connected to the outer wall of the conductive ring 10 is fixedly provided in the connection block 201 at the left end, and a plug hole 202 for inserting a cable is provided in the middle of the connection block 201, and one end of the conductive block 203 electrically connected to the cable is located in the plug hole 202, and the conductive block 203 is electrically connected to the cable;

[0038] like Figure 2 and Figure 3 As shown, the rotating connection portion includes a connecting piece 204 and two rotating shafts 205. The connecting piece 204 is located between two adjacent connecting blocks 201. Both sides of the connecting block 201 close to the connecting piece 204 are provided with grooves for the edges of the connecting piece 204 to be embedded; the two rotating shafts 205 are located on both sides of the connecting piece 204 close to the connecting block 201. The rotating shaft 205 passes through the edges of the connecting piece 204 and the connecting block 201, and the axis of the rotating shaft 205 is perpendicular to the opening direction of the groove. The rotating shaft 205 is rotatably connected to the connecting piece 204 or the connecting block 201; the edge of the connecting piece 204 is in an arc shape that fits the inner wall of the groove.

[0039] At the same time, if Figure 2 and Figure 3As shown, the connection block 201 is provided with a serial connection hole 206 for the cables to pass through, the serial connection hole 206 is cylindrical, and the serial connection hole 206 is located in the middle of the connection block 201 .

[0040] When the automobile battery terminal connection structure of the present embodiment is in use, the length of the connecting belt 20 can be controlled according to the length of the cable, so that the excess length of the cable can be inserted into the socket 202 and electrically connected to the conductive block 203 after passing through the serial holes 206 on the connecting blocks 201 in sequence; in the process of adjusting the length of the connecting belt 20, the connecting belt 20 can be quickly extended or shortened by disassembling the connecting piece 204 and the rotating shaft 205 at the connecting block 201, so that the length of the connecting belt 20 adapts to the length required for the cable when it is fixed.

[0041] When the cable is inserted into the jack 202 , the rubber connecting piece 204 can protect the cable from bending and folding, and can also generate greater static friction with the cable to fix the cable.

[0042] When installing the automobile battery terminal connection structure onto the terminal 2, loosen the nut 104 to increase the distance between the first insulating block 101 and the second insulating block 102, thereby facilitating the vertical insertion of the conductive ring 10 onto the terminal 2. When the conductive ring 10 is installed to the bottom of the terminal 2, tighten the nut 104 on the bolt 103, and the first insulating block 101 and the second insulating block 102 approach each other. The first insulating block 101 and the second insulating block 102 drive the two ends of the conductive ring 10 to approach each other, so that the inner wall of the conductive ring 10 fits against the outer wall of the terminal 2, thereby realizing stable conduction of electrical energy.

[0043] After the conductive ring 10 is installed, the connecting belt 20 is attached to the side wall or upper surface of the car battery 1. The connecting belt 20 can make the excess length of the cable more neat; at the same time, the cable is attached to the car battery 1, so that other structures can be easily installed and arranged in other spaces in the car.

[0044] When the car vibrates while moving, the conductive ring 10 is in surface contact with the terminal 2, and due to the cooperation of the nut 104, the bolt 103, the first insulating block 101 and the second insulating block 102, the conductive ring 10 can be tightly installed on the terminal 2, which can reduce the risk of the conductive ring 10 and the terminal 2 loosening and falling off.
