Description

Technical Field

[0001] The utility model relates to the field of new energy high-voltage electrical control units and systems, and in particular to a high-voltage control box pre-charge module rapid assembly structure. Background Art

[0002] like Figure 1 As shown in FIG, a schematic diagram of a high-voltage pre-charging circuit in the prior art is shown, which primarily includes a main positive relay KA1, a pre-charging relay KA2 and a pre-charging resistor RS connected in series, and a main negative relay KA3. The circuit formed by the series connection of the pre-charging relay KA2 and the pre-charging resistor RS constitutes a pre-charging module 2, which is connected in parallel to the main positive relay KA1. A similar pre-charging module is disclosed in patent application number CN108964167B.

[0003] The above-mentioned pre-charge module 2, pre-charge relay and pre-charge resistor are encapsulated in a carrier, and two high-voltage interfaces are brought out. When forming a high-voltage pre-charge circuit, the high-voltage interfaces at both ends of the pre-charge module 2 need to be connected in parallel to the two ends of the main positive relay. Traditional electrical connection methods usually use snap-on, twisted or screw connections, which not only have low installation efficiency, but also are prone to loosening at the connection, posing a major safety hazard, and therefore need to be improved. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the utility model provides a high-voltage control box pre-charge module quick assembly structure, which can realize the quick connection of the pre-charge module and the main positive relay, thereby improving installation efficiency and reducing safety hazards.

[0005] In order to solve the above technical problems, the present invention is solved by the following technical solutions:

[0006] A high-voltage control box pre-charge module quick assembly structure includes a main positive relay and a pre-charge module. The main positive relay and the pre-charge module are both installed on a base. Two conductive bars are provided on the side of the main positive relay. One end of the two conductive bars is respectively fixed and electrically connected to the two conductive interfaces of the main positive relay, and the other end is provided with a conductive plug extending upward. Two conductive connecting plates are provided on the side of the pre-charge module. The two conductive connecting plates are respectively connected to the two conductive connection ports of the pre-charge module as a whole. Both conductive connecting plates are provided with sockets for the two conductive plugs to be plugged in and conduct electricity.

[0007] The above solution allows for quick connection between the pre-charge module and the main positive relay through the plug-in connection between the conductive insert and the socket, ensuring electrical continuity between the two. This not only improves the efficiency and convenience of pre-charge module installation but also prevents loose connections, ensuring safety.

[0008] Preferably, both side edges of the socket are provided with conductive clips extending upward and used for clamping the conductive plug.

[0009] By adopting the above solution, the conductive clip can not only improve the connection tightness between the conductive plug and the socket, but also increase the contact area between the two, thereby improving the conductivity between the conductive connecting piece and the conductive bar.

[0010] Preferably, the number of the conductive clips on one side of the socket is one, and the number of the conductive clips on the other side is two.

[0011] With this solution, the two conductive clips on one side of the socket create two fulcrums on the side of the conductive plug, improving both clamping performance and increasing the contact area between the clips and the plug, thereby enhancing conductivity. The single conductive clip on the other side of the socket not only exerts a clamping force on the plug but also reduces the resistance to insertion, further enhancing installation efficiency and convenience.

[0012] Preferably, a guiding slope is provided at the end of the conductive plug.

[0013] With the above solution, the guiding slope has a guiding function, which can help the conductive plug to open the conductive clip, further improving the installation efficiency and convenience of the pre-charged module.

[0014] Preferably, the conductive connecting piece is covered with an insulating shell, and the insulating shell is provided with an escape hole for the conductive clip to pass through.

[0015] By adopting the above solution, the insulating shell can reduce the exposed portion of the conductive connecting piece, thereby reducing the risk of short circuit or corrosion of the conductive connecting piece.

[0016] Preferably, one end of the conductive bar close to the main positive relay is fixed to the conductive interface of the main positive relay by a conductive screw.

[0017] By adopting the above solution, the conductive screw can not only increase the connection stability of the conductive bus, but also ensure the conductive performance between the conductive bus and the conductive interface.

[0018] Preferably, at least one first lug is provided on the side of the main positive relay, and a first connecting column corresponding to the first lug is provided on the base, and the first lug is fixed to the first connecting column by a first screw.

[0019] By adopting the above solution, the first lug is fixed to the first connecting column by the first screw, so that the main positive relay can be installed on the base and the stability of the installation can be guaranteed.

[0020] Preferably, at least one second lug is provided on the side of the pre-filled module, and a second connecting column corresponding to the second lug is provided on the base, and the second lug is fixed to the second connecting column by a second screw.

[0021] By adopting the above solution, the second ear is fixed to the second connecting column by the second screw, so that the pre-filled module can be installed on the base and the stability of the installation can be guaranteed.

[0022] By adopting the above technical solution, the present invention has a significant technical effect: through the plug-in fit between the conductive insert and the socket, the pre-charge module and the main positive relay can be quickly connected and the circuit connectivity between the two can be ensured. This not only improves the installation efficiency and convenience of the pre-charge module, but also prevents the connection from loosening, thereby ensuring safety.

[0030] The present invention is described in further detail below with reference to the accompanying drawings and embodiments.

[0031] like Figure 2As shown, the present embodiment discloses a high-voltage control box pre-charge module quick assembly structure, including a main positive relay 1 and a pre-charge module 2, the pre-charge module 2 includes a pre-charge relay 21 and a pre-charge resistor 22, both of which are encapsulated in a shell to achieve modularization, which is common knowledge in the field and will not be elaborated here.

[0032] like Figures 2 to 5 As shown, in order to achieve rapid installation and wiring of the pre-charge module 2, the main positive relay 1 and the pre-charge module 2 are both installed on a base 3. Specifically, at least one first lug 15 is provided on the side of the main positive relay 1, and a first connecting column 16 corresponding to the first lug 15 is provided on the base 3. The first lug 15 is fixed to the first connecting column 16 by a first screw 17. Correspondingly, at least one second lug 18 is provided on the side of the pre-charge module 2, and a second connecting column 19 corresponding to the second lug 18 is provided on the base 3. The second lug 18 is fixed to the second connecting column 19 by a second screw 20. Two conductive bars 4 are provided on the side of the main positive relay 1, one end of the two conductive bars 4 is respectively fixed and electrically connected to the two conductive interfaces 5 of the main positive relay 1 by conductive screws 14, and the other end is integrally provided with a conductive plug 6 extending upward. Two conductive connecting pieces 7 are provided on the side of the pre-filling module 2. The two conductive connecting pieces 7 are integrally connected to the two conductive connection ports of the pre-filling module 2. Both conductive connecting pieces 7 are provided with sockets 9 for the two conductive plugs 6 to be plugged in and conduct.

[0033] like Figure 6 As shown, to enhance the connection stability and conductivity between the conductive insert 6 and the socket 9, conductive clips 10 extending upward and used to clamp the conductive insert 6 are integrally provided on both sides of the socket 9. There is one conductive clip 10 on one side of the socket 9, and two conductive clips 10 on the other side.

[0034] like Figure 6 As shown, in order to improve the efficiency and convenience of the connection between the conductive plug 6 and the socket 9 , a guiding slope 11 is provided at the end of the conductive plug 6 .

[0036] The specific usage process is as follows:

[0037] When assembling the high-voltage control box, first install the main positive relay 1 pre-installed with the conductive bar 4 on the base 3 so that the first ear 15 is opposite the first connecting column 16, and then fix the first ear 15 to the first connecting column 16 with the first screw 17, thereby completing the locking of the main positive relay 1.

[0038] At this point, the pre-filled module 2 is mounted vertically on the base 3, allowing the conductive inserts 6 on the conductive bar 4 to prop open the conductive clips 10 on the corresponding sockets 9 via the guiding slopes 11. Once the pre-filled module 2 is in place, the conductive inserts 6 are fully inserted into the corresponding sockets 9, and the conductive clips 10 establish an electrical connection between the two. Simultaneously, the second lugs 18 on the pre-filled module 2 dock with the second connecting posts 19 on the base 3, and the two are secured together using second screws 20, thus completing the locking and installation of the pre-filled module 2 and the parallel connection between the pre-filled module 2 and the main positive relay 1.
