With the gradual improvement of automobile technology and the increasing use needs of users, the number of electronic devices on vehicles is gradually increasing. Different electronic devices have different requirements for power consumption, so the requirements for the power distribution capacity of the vehicle are higher. Traditional vehicles generally connect the positive pole of the battery through the power distribution box to distribute power. However, the current carrying capacity of the traditional power distribution box is relatively fixed, and it is difficult to meet the power demand of different electronic devices.

The researchers of this application have found through research that the output components of traditional power distribution boxes are generally integrally formed with the housing of the power distribution box, which makes it impossible to replace the output components. Therefore, the current carrying capacity of traditional power distribution boxes is relatively fixed, resulting in The power box cannot meet the power demand of different electronic devices.

In view of this, the present application proposes a power distribution box, which aims to solve the problem that the traditional power distribution box has a relatively fixed ampacity and is difficult to meet the power requirements of different electronic devices. 1 to 5 are schematic structural views of an embodiment of a power distribution box proposed in the present application.

Please refer to FIG. 1 , the power distribution box 100 proposed in this application is used to distribute the electric power of the battery of the vehicle. The positive battery plug 1 is used to connect the pole of the battery. The housing 2 is provided with an installation cavity 21 , and the housing 2 is provided with an input port 24 and an output port 25 respectively communicating with the installation cavity 21 . The connection assembly 3 includes an input terminal block 31 and an output element 32 respectively installed in the installation cavity 21 . One end of the input terminal block 31 protrudes from the input port 24 to be connected to the positive battery plug 1 , and the other end is connected to the output element 32 . The output element 32 is located close to the output port 25 and is detachable. The output element 32 is used for connecting with electronic devices on the vehicle.

In the technical solution of the present application, the power distribution box 100 is connected to the pole column of the storage battery through the positive battery plug 1, the positive battery plug 1 is connected to the input terminal block 31, and the input terminal block 31 is also connected to the output element 32, and finally the The output element 32 is connected to the electronics on the vehicle. Wherein, the output element 32 is disposed close to the output port 25, and the output element 32 is detachable, so the output element 32 can be replaced.

It should be noted that different output elements 32 have different current carrying capacity, so when the power distribution box needs to meet the power requirements of different electronic devices, the power distribution box 100 can be installed with different output elements 32, thereby increasing or reducing Small carrying capacity. In addition, the power distribution box 100 is generally provided with multiple power distribution branches, and each power distribution branch is connected to different electronic devices, so different types of output elements 32 can be installed in different power distribution branches, so that Make the carrying capacity of each distribution branch different.

Electricity leakage should be avoided as far as possible during transportation. Therefore, in specific applications, the power distribution box 100 also includes a housing 2, and the housing 2 is provided with an installation cavity 21 for the installation of the connection assembly 3 to avoid leakage of the connection assembly 3. In addition, an insulating glue layer is generally laid on the outside of the housing 2 to prevent the housing 2 from leaking.

Referring to FIG. 1 and FIG. 5 , in some embodiments, the output element 32 includes a conductive rod 321 and a ring terminal 322 . The conductive rod 321 is detachably installed in the installation cavity 21 . The ring terminal 322 is sheathed on the conductive rod 321 , and the ring terminal 322 is used for connecting with electronic devices on the vehicle. Wherein, the output element 32 includes a variety of conductive rods 321 , and each type of conductive rod 321 has a different diameter.

At this time, the conductive rod 321 can be regarded as a conductive cable, so the diameter of the conductive rod 321 roughly determines its current carrying capacity. When the power distribution box 100 is replaced with a conductive rod 321 with a larger diameter, the current carrying capacity of the power distribution box 100 will increase, and when the conductive rod 321 with a smaller diameter is replaced, the current carrying capacity of the power distribution box 100 will decrease. Although the current carrying capacity of the conductive rod 321 can transport the current of the storage battery to the electronic device, the power-taking capability of the electronic device also determines the electric energy it can obtain. Therefore, the output element 32 also includes a ring terminal 322. The ring terminal 322 is sheathed on the conductive rod 321, thereby fully contacting the conductive rod 321, increasing the electric capacity of the electronic device, so that the electronic device can obtain the required electric energy.

In some embodiments, the conductive rod 321 includes a conductive bolt 321 a, and the conductive bolt 321 a is disposed in the installation cavity 21 . The output element 32 further includes a conductive nut 323 , which is used for screwing with the conductive bolt 321 a to limit the ring terminal 322 on the housing 2 .

In actual application, the conductive bolt 321 a is passed through a predetermined through hole on the housing 2 , and the conductive bolt 321 a is electrically connected to the input terminal block 31 . The ring terminal 322 is sheathed on the conductive bolt 321a, so as to obtain electricity for the electronic device. When the conductive nut 323 is screwed to the conductive bolt 321a, the conductive nut 323 will be pressed against the inner wall of the installation cavity 21, thereby fixing the conductive bolt 321a. In addition, the ring terminal 322 will be limited between the conductive nut 323 and the housing 2 , so as to ensure that the ring terminal 322 receives electricity stably.

In actual application, the installation environment of the vehicle is relatively narrow, so the installation of the power distribution box 100 is required to be more compact. Therefore, in some embodiments, the input terminal block 31 includes a first portion 311 protruding from the input port 24 and a second portion 312 installed in the installation cavity 21 . The first portion 311 and the second portion 312 can be perpendicular to each other.

Please refer to Fig. 2 and Fig. 4, in the traditional power distribution box, the input port 24 and the output port 25 are generally arranged oppositely, and this makes the positive battery plug 1 and the shell 2 also need to be installed in sequence along the same direction, which makes the distribution box The electric box needs a relatively wide space when installing. In this application, the first part 311 is perpendicular to the second part 312 , so that the positive battery plug 1 and the casing 2 can be arranged perpendicular to each other, which makes the installation of the power distribution box 100 more compact and requires less space.

In some embodiments, the positive battery plug 1 includes a connecting ring 11 and an adapter 12 . The connecting ring 11 is sheathed on the outside of the pole of the battery. The adapter piece 12 is connected to the connection ring 11 , and the adapter piece 12 is detachably connected to the input terminal block 31 . The connecting ring 11 is sheathed on the outside of the pole of the battery so as to be electrically connected with the pole of the battery. The adapter 12 is fixedly connected to the connecting ring 11 and detachably connected to the input terminal block 31 , so that the power of the storage battery is input into the housing 2 through the input terminal block 31 . In practical application, the adapter 12 can be integrated with the connecting ring 11 , so that the structure of the positive battery plug 1 is more stable and compact, and the installation is more convenient.

The positive battery plug 1 needs to transport the power of the storage battery to the connection assembly 3 , so the positive battery plug 1 has a certain risk of electric leakage. Therefore, in some embodiments, the positive battery plug 1 further includes an insulating protective sheath 13 corresponding to the connecting collar 11 and the adapter 12 , and the insulating sheath 13 is sheathed on the outside of the connecting collar 11 and the adapter 12 . The insulating protective sleeve 13 can isolate the connecting ring sleeve 11 and the adapter 12 from the outside world, so as to avoid electric leakage.

Please refer to FIG. 1 and FIG. 3 , in some embodiments, the insulating protective cover 13 is provided with a first opening 131 and a second opening 132, and the first opening 131 is used for extending the pole of the battery into the connecting ring sleeve 11, The second opening 132 is used for the input terminal block 31 to extend in to connect with the adapter 12 . An installation opening 133 is also provided on the insulating protective cover 13 , and the installation opening 133 communicates with the second opening 132 .

In a specific application, the transfer-in terminal block needs to extend into the second opening 132 of the insulating protective cover 13 so as to be installed with the transfer member 12 . However, the second opening 132 cannot be set too large, otherwise the insulating protective cover 13 may fall off from the outside of the connecting ring sleeve 11 and the adapter 12, and if the second opening 132 is not large enough, the connection between the adapter 12 and the input terminal block 31 will be more difficult. Therefore, the insulating protective cover 13 is also provided with an installation opening 133 communicating with the second opening 132, and the second opening 132 can be expanded to a certain extent through the installation opening 133, so that the input terminal block 31 can be more conveniently inserted into the second opening. 132, which also enables the input terminal block 31 to be connected to the adapter 12 more smoothly.

Please refer to FIG. 1 and FIG. 2 , in some embodiments, the housing 2 includes a first housing 22 and a second housing 23 oppositely disposed, and the first housing 22 and the second housing 23 are interlocked to form an installation cavity. twenty one. One of the first housing 22 and the second housing 23 is provided with a lock 28, and the other corresponding lock 28 is provided with a lock groove 26, and the lock 28 is configured to be connected between the first housing 22 and the second housing. 23 can be buckled and connected with the lock groove 26 when buckled.

The housing 2 is provided with an installation cavity 21 , and the connection assembly 3 is installed in the installation cavity 21 . The connection assembly 3 can extend into the installation cavity 21 from the input port 24 and the output port 25, but the installation operation is relatively difficult. Therefore, the casing 2 includes a first casing 22 and a second casing 23, and the first casing 22 and the second casing 23 are interlocked to form an installation cavity 21, so the connecting assembly 3 can be installed first, and then the second casing can be installed. A housing 22 is assembled with a second housing 23 . In addition, the first shell 22 and the second shell 23 are fastened and connected by the lock 28 and the lock groove 26. Of course, the first shell 22 can also be connected by other means, such as screw connection, or in the first The outer casing 22 and the second casing 23 are sheathed with insulating rubber sleeves to limit and fix the first casing 22 and the second casing 23 .

Referring to FIG. 1 and FIG. 2 , in some embodiments, a side of the input terminal block 31 close to the output element 32 is provided with a plurality of electrical connection points at intervals. The connection assembly 3 includes a plurality of output elements 32 correspondingly connected to the electrical connection points one by one, and each electrical connection point and the corresponding output element 32 form a power distribution branch circuit. The power distribution box 100 also includes an insulating partition 27 for separating two adjacent power distribution branches.

In actual application, the electronic devices on the vehicle have different power requirements, so the power distribution box 100 is provided with multiple power distribution branches. The power distribution branch is composed of output elements 32 and electrical connection points, and different output elements 32 have different ampacities, so different power distribution branches can supply power to different electronic devices. Distribution branches cannot be connected to each other, otherwise they will affect each other. Therefore, in some embodiments, the power distribution box 100 further includes an insulating partition 27, and the insulating partition 27 can separate adjacent power distribution branches, so as to prevent the power distribution branches from being conducted with each other.
