Description

Technical Field

[0001] This invention relates to the field of tooling equipment technology, and in particular to a busbar installation tool for high-voltage connectors. Background Technology

[0002] Currently, the high-voltage device connectors in the new energy industry primarily use standardized connectors. The internal connection between the connector and the entire battery system is achieved by bolting the connector to the busbar. The connector's metal terminals connect to the busbar, and a flange is provided on the outer edge of the connector. During the assembly of individual connectors and busbars, manual assembly is often used, leading to problems such as busbar misalignment, damage, low installation efficiency, and insufficient torque due to ineffective fixing.

[0003] For example, Chinese Patent Publication No. CN110994269A, published on April 10, 2020, entitled "A High-Voltage Connector for New Energy Vehicles," includes a copper busbar, a metal housing, a metal cover, an insulating shell, an insulating cover, metal terminals, a shielding mechanism, and a rear cover. The metal housing and the metal cover form a first receiving cavity. The side wall and bottom of the metal housing are respectively provided with a first opening and a second opening. The insulating shell and the insulating cover are fastened together to form a second receiving cavity. The copper busbar is disposed in the second receiving cavity and protrudes from the insulating shell. The copper busbar extends outward from the first opening and is perpendicular to the metal housing. The shielding mechanism and the rear cover are sleeved on the high-voltage wiring harness and connected to the copper busbar through metal terminals. The shielding mechanism is fixed to the metal housing through the rear cover. The right-angle structure reduces the space required for installing the high-voltage connector and electrical components. The insulating shell uses an internal secondary locking structure to replace the high-voltage interlock circuit, ensuring that the high-voltage connector cannot be disassembled from the outside, thus reducing the overall cost of the high-voltage connector while ensuring personnel safety.

[0004] The drawbacks of existing patents are that the assembly of existing connector components and busbar components often involves manual assembly, which leads to problems such as busbar misalignment, damage, and low installation efficiency. Summary of the Invention

[0005] The purpose of this invention is to solve the problems of manual assembly, which often leads to misalignment, damage, and low installation efficiency of busbars during the assembly of individual connectors and busbars. This invention provides a busbar installation fixture for high-voltage connectors that improves installation efficiency, assembly quality, and protects the busbar from damage.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A busbar installation fixture for high-voltage connectors, comprising:

[0008] A connector positioning seat, wherein the connector positioning seat is provided with a fixing groove for placing a connector and a limiting component for limiting the connector in the fixing groove;

[0009] A bus positioning seat is provided, which is mounted on a connector positioning seat and has positioning components for fixing the bus. The connector is limited in the fixing groove of the connector positioning seat by a limiting component, and the bus is fixed on the bus positioning seat by the positioning component. After fixing, the metal terminals of the connector and the connection between the bus and the bus are bolted together. This solution reduces the difficulty of connector assembly, improves installation quality, and avoids product defects and damage during installation. During assembly, the connector is limited in the fixing groove by the limiting component, and several buses are fixed on the bus positioning seat by the positioning component. At this time, the bus and the metal terminals of the connector mate, and the connection between the connector and the bus is bolted together. This avoids the problems of not being able to fix the bus properly and not being able to maintain a safe and effective distance between the copper busbars during manual assembly, improves the assembly accuracy, and ensures that the bolt tightening torque meets the corresponding standard.

[0010] Preferably, the limiting component includes a fixing plate and a positioning groove disposed on the connector positioning seat. The positioning plate cooperates with the positioning groove, and the fixing groove is located at the bottom of the positioning groove. The positioning plate has a through hole that cooperates with the metal terminals of the connector. When the connector is located in the positioning groove, the upper end face of the connector is flush with the bottom of the positioning groove. The fixing plate limits the connector within the positioning groove, and the metal terminals of the connector pass through the through hole and cooperate with the busbar on the busbar positioning seat.

[0011] Preferably, the limiting assembly further includes a locking member for locking and limiting the connector below the fixing plate. The lower surface of the fixing plate has a downward-facing screw hole, and the locking member is threaded into the screw hole. The fixing groove has a clearance hole for avoiding the locking member. During installation, the locking member passes through the connector and locks into the screw hole. The connector is limited below the fixing plate by the locking member. After the connector and the fixing plate are fixed, they are placed on the fixing groove. The fixing plate is located in the positioning groove, reducing the gap between the fixing groove and the connector. The fixing plate in the positioning groove plays a positioning role, so that the connector is aligned. The screws are tightened through the fixing hole and the flange and the screw hole on the fixing plate, so that the connector is fixed on the connector positioning seat and does not shift. The fixing plate plays a supporting role.

[0012] Preferably, the positioning component includes a buttonhole on the busbar positioning seat and a fixing button that mates with the buttonhole. The fixing button passes through the busbar and is screwed into the buttonhole, thus positioning the busbar on the busbar positioning seat. The busbar has a through hole, through which the fixing button passes and is inserted into the buttonhole, fixing the busbar to the busbar positioning seat and maintaining its assembled state.

[0013] Preferably, the positioning component further includes a limiting groove disposed above the busbar positioning seat, the button hole being located within the limiting groove, and the limiting groove engaging with the fixed end of the busbar. Each limiting groove corresponds one-to-one with a busbar, ensuring a safe distance between multiple busbars.

[0014] Preferably, the bottom of the positioning groove is provided with a limiting pin, and the fixing plate is provided with fixing pin holes corresponding to the limiting pins. The limiting pins are used to limit the fixing plate.

[0015] Preferably, the upper edge of the connector mounting base is provided with a groove that extends to the bottom of the positioning groove.

[0016] Preferably, the bottom of the fixing groove is provided with a limiting hole that mates with the outer wall of the connector. The limiting hole is opened in the vertical direction, and the outer wall of the connector is provided with a flange, which is limited on the fixing groove.

[0017] Preferably, the bottom of the limiting groove is inclined, and the inclined surface is connected to the outer wall of the manifold positioning seat. The inclined surface is connected to the manifold.

[0018] The outer wall fits together so that the end of the busbar that mates with the metal terminals of the connector is horizontally distributed.

[0019] Preferably, the busbar positioning seat is fixed above the connector positioning seat by bolts. Different specifications of busbar positioning seats and connector positioning seats can be assembled according to different specifications of busbars and connectors. Replacement and assembly are convenient.

[0020] Therefore, the present invention has the following beneficial effects: improving the installation efficiency of connectors and busbars, improving assembly quality, and protecting busbars and connectors from damage. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0030] Example 1, as Figures 1 to 5 The diagram illustrates a busbar mounting fixture for high-voltage connectors, comprising: a connector positioning seat 1, which has a fixing groove 2 for placing the connector and a limiting component for positioning the connector within the fixing groove 2; and a busbar positioning seat 3, which is mounted on the connector positioning seat 1 and has a positioning component for fixing the busbar. The connector is positioned within the fixing groove 2 of the connector positioning seat 1 by the limiting component, and the busbar is fixed to the busbar positioning seat 3 by the positioning component. After fixing, the metal terminals of the connector 16 are fastened to the busbar connection point by bolts.

[0031] Furthermore, such as Figure 1 , Figure 3 , Figure 5 As shown, the limiting assembly includes a fixing plate 5 and a positioning groove 6 disposed on the connector positioning seat 1. The positioning plate mates with the positioning groove 6, and the fixing groove 2 is located at the bottom of the positioning groove 6. The positioning plate has through holes that mate with the metal terminals of the connector. When the connector is located in the positioning groove 6, the upper end face of the connector is flush with the bottom of the positioning groove 6. The fixing plate 5 limits the connector to be within the positioning groove 6, and the metal terminals of the connector pass through the through holes to mate with the busbar on the busbar positioning seat 3.

[0032] Furthermore, such as Figure 5As shown, the limiting assembly also includes a locking member 7 for locking and limiting the connector below the fixing plate 5. The lower surface of the fixing plate 5 has a downward-facing screw hole 9. The locking member 7 is threaded into the screw hole 9. The fixing groove 2 has a clearance hole for avoiding the locking member 7. During installation, the locking member 7 passes through the connector and locks it in the screw hole 9. The connector is limited below the fixing plate 5 by the locking member 7. After the connector and the fixing plate 5 are fixed, they are placed on the fixing groove 2. The fixing plate 5 is located in the positioning groove 6, which reduces the gap between the fixing groove 2 and the connector. The fixing plate 5 is located in the positioning groove 6 to provide positioning, so that the connector is aligned. The screws are tightened through the fixing hole 8 and the flange and the screw hole 9 on the fixing plate 5, so that the connector is fixed on the connector positioning seat 1 without displacement. The fixing plate 5 provides support.

[0033] Furthermore, such as Figure 1 , Figure 2 , Figure 4 As shown, the positioning assembly includes a button hole on the busbar positioning seat 3 and a fixing button 11 that mates with the button hole. The fixing button 11 passes through the busbar and is screwed into the button hole, thus limiting the busbar to be positioned on the busbar positioning seat 3. The busbar has a through hole, and the fixing button 11 passes through the through hole of the busbar and is inserted into the button hole, fixing the busbar on the busbar positioning seat 3 and maintaining the busbar in its assembled state.

[0034] Furthermore, such as Figure 1 , Figure 2 As shown, the positioning component also includes a limiting groove 10 disposed above the busbar positioning seat 3, with a button hole located within the limiting groove 10. The limiting groove 10 engages with the fixed end of the busbar. The limiting groove 10 corresponds one-to-one with the busbars, ensuring a safe distance between multiple busbars.

[0035] Furthermore, such as Figure 1 As shown, the bottom of the positioning groove 6 is provided with a limiting pin 12, and the fixing plate 5 is provided with fixing pin holes 13 corresponding to the limiting pins 12. The limiting pins 12 are used to limit the fixing plate 5.

[0036] Furthermore, such as Figure 2 As shown, the upper edge of the connector mounting base is provided with a groove 14, which extends to the bottom of the positioning groove 6.

[0037] Furthermore, such as Figure 1 As shown, the bottom of the fixing groove 2 is provided with a limiting hole 4 that mates with the outer wall of the connector. The limiting hole 4 is opened in the vertical direction, and the outer wall of the connector is provided with a flange 17. The flange is limited on the fixing groove 2, and the lower end of the connector extends into the limiting hole 4.

[0038] Furthermore, such as Figure 5 As shown, the bottom of the limiting groove 10 is inclined, and the inclined surface connects to the outer wall of the busbar positioning seat 3. The inclined surface connects to the busbar...

[0039] The outer wall fits together so that the end of the busbar that mates with the metal terminals of the connector is horizontally distributed.

[0040] The busbar installation fixture for high-voltage connectors described in the above embodiments reduces the difficulty of connector assembly, improves installation quality, and avoids product defects and damage during installation. During assembly, the connector is positioned within the fixing groove 2 by a limiting component, and several busbars are fixed to the busbar positioning seat 3 by a positioning component. At this point, the metal terminals of the busbars and connectors mate, and the connection between the connector and the busbars is secured with bolts. This avoids the problems of manual assembly where it is impossible to secure the busbars or maintain a safe and effective distance between them, improving assembly accuracy and ensuring that the bolt tightening torque meets the corresponding standards.

[0041] Example 2, based on Example 1, such as Figure 5 As shown, the busbar positioning seat 3 is fixed above the connector positioning seat 1 by bolts. Different specifications of busbar positioning seats 3 and connector positioning seats 1 can be assembled according to different specifications of busbars and connectors.
