Description

Technical Field

[0001] This utility model relates to the field of conductive connector technology, specifically to negative electrode conductive connectors. Background Technology

[0002] Conductive connectors refer to all electronic components or parts used to establish and maintain current paths. Their core function is to reliably and efficiently transmit current or electrical signals; The battery packs of new energy vehicles require conductive connectors to connect the negative and positive terminals of the battery. When the conductive connector is fixed to the negative terminal of the battery, it is completely attached to the negative terminal without any additional force for reinforcement. During vehicle operation, vibrations frequently occur, making the installation of the conductive connector to the negative terminal of the battery not secure enough, and it is easy to detach during vibrations. Therefore, there is an urgent need in the market to develop negative terminal conductive connectors to help people solve the existing problems. Utility Model Content

[0003] The purpose of this invention is to provide a negative electrode conductive connector to solve the problem mentioned in the background art that the battery negative electrode conductive connector is not securely installed and is prone to disconnection when vibration occurs.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a negative electrode conductive connector, comprising: The conductive component body includes contact connecting pieces, mounting connecting pieces, and connectors; The mounting connector is a frustum structure with a suspended groove at the bottom, and the mounting connector is elastic.

[0005] The above technical solution designs the mounting connector, which connects to the negative terminal of the battery, as a frustum structure, creating a suspended groove at the bottom. When using screws for connection and fixation, the mounting connector is elastic, and because it is suspended, it tends to deform downwards. Simultaneously, the screw has an upward pushing force, thus subjecting the screw to stronger pressure during installation. This is similar to adding a washer between the screw and the component. By replacing the washer with this structure, the possibility of accidental contact or oxidation aging leading to leakage is avoided, as is the possibility of metal fusion. This improves the stability of the installation and prevents the negative conductive connector from detaching during vehicle vibration, thereby enhancing safety.

[0006] In a preferred embodiment, the present invention can be further configured such that: the inner side of the mounting connecting piece is provided with mounting holes, the mounting holes including a round hole and two positioning holes.

[0007] The above technical solution provides mounting holes on the mounting connector for screws to pass through and connect with the battery electrodes for fixation. The positioning holes facilitate positioning, and the groove below the mounting connector also assists in disassembly. Traditional patch mounting results in no gap between the battery negative terminal and the connector, making it impossible to effectively remove the connector when metal fusion occurs. The groove allows a screwdriver to be inserted under the mounting connector to pry it apart from the battery negative terminal, thus facilitating disassembly.

[0008] In a preferred embodiment, the present invention can be further configured such that an epoxy resin coating layer is provided on the outer side of the connector.

[0009] The above technical solution involves wrapping the outside of the connector with an epoxy resin coating layer to prevent thermal aging and avoid oxidation of metal parts under high temperature for a long time. At the same time, the epoxy resin coating layer can also isolate air, prevent rust and corrosion, and increase the service life of the conductive connector.

[0010] In a preferred embodiment, the present invention can be further configured such that the outer surface of the connector is provided with contact rough holes.

[0011] The above technical solution utilizes sandblasting to create numerous densely packed rough contact holes on the outer surface of the connector. When the epoxy resin coating layer is wrapped onto the outer surface of the connector, the rough holes can increase the adhesion area, form a physical anchoring "groove," enhance the mechanical interlocking effect, effectively prevent the epoxy resin coating layer from peeling off, and improve stability and reliability.

[0012] In a preferred embodiment, the present invention can be further configured such that the connector is provided with a kink.

[0013] The above technical solution utilizes a kink design to create a stepped structure in the middle of the epoxy resin coating layer. This stepped structure provides support and further prevents the epoxy resin coating layer from peeling off.

[0014] Compared with the prior art, the beneficial effects of this utility model are: This utility model designs the mounting connector, which connects to the negative terminal of the battery, as a frustum structure, creating a suspended groove at the bottom. When using screws for connection and fixation, the mounting connector is elastic, and because it is suspended, it tends to deform downwards. Simultaneously, the screw has an upward pushing force, thus subjecting the screw to stronger pressure during installation. This is similar to adding a washer between the screw and the component. By replacing the washer with this structure, the possibility of accidental contact or oxidation aging leading to leakage is avoided, as is the possibility of metal fusion. This improves the stability of the installation and prevents the negative conductive connector from detaching during vehicle vibration, thereby enhancing safety.

[0015] The mounting holes on the mounting connector of this utility model are used to allow screws to pass through and connect and fix with the battery electrodes. The positioning holes facilitate positioning, and the groove below the mounting connector can also assist in disassembly. Traditional patch mounting results in no gap between the battery negative terminal and the connector, making it impossible to effectively remove when metals fuse. The groove allows a screwdriver to be inserted under the mounting connector to pry the mounting connector away from the battery negative terminal, thus facilitating disassembly.

[0016] This invention wraps an epoxy resin coating around the outside of the connector to prevent thermal aging and avoid oxidation of metal parts under high temperatures for extended periods. The epoxy resin coating also isolates the connector from air, preventing rust and corrosion, and increasing the service life of the conductive connector.

[0017] This invention utilizes a sandblasting process to create numerous densely packed, rough contact holes on the outer surface of the connector. When the epoxy resin coating layer is wrapped around the outer surface of the connector, the rough holes can increase the adhesion area, forming a physical anchoring "groove" to enhance the mechanical interlocking effect. This can effectively prevent the epoxy resin coating layer from peeling off, thereby improving stability and reliability. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] In the description of this application, it should be noted that the terms "upper," "lower," "inner," "outer," "top / bottom," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0023] Please see Figure 1 One embodiment of this utility model provides a negative electrode conductive connector, comprising: The conductive component body 1 includes a contact connecting piece 2, a mounting connecting piece 3, and a connector 6. The contact connecting piece 2 and the mounting connecting piece 3 are both integrated with the connector 6. The contact connecting piece 2 and the mounting connecting piece 3 are set at a 90-degree angle to the connector 6. The contact connecting piece 2, the mounting connecting piece 3, and the connector 6 are combined to form a zigzag shape.

[0024] The mounting connector 3 has a frustum structure with a suspended groove at the bottom. The mounting connector 3 is elastic and has two contact feet at the bottom for connecting to the negative terminal of the battery. During installation, when screws are used for connection and fixation, the elasticity of the mounting connector 3, coupled with its suspended position, causes it to deform downwards, giving the screw an upward lifting force. This allows the screw to withstand stronger pressure, similar to adding a washer between the screw and the component. This structure replaces the washer, preventing accidental contact or oxidation / aging leakage, and also preventing metal fusion. This improves the stability of the installation and prevents the negative conductive connector from detaching during vehicle vibrations, thus enhancing safety.

[0025] Meanwhile, the groove below the mounting connector 3 can also assist in disassembly. Traditional patch mounting results in no gap between the battery negative terminal and the connector, making it impossible to effectively remove when the metals fuse. The groove allows a screwdriver to be inserted under the mounting connector 3 to pry the mounting connector 3 away from the battery negative terminal, thus facilitating disassembly.

[0026] Please see Figure 1 The inner side of the mounting connector 3 is provided with mounting holes 4. The mounting holes 4 include a round hole and two positioning holes. The mounting holes 4 and the two positioning holes are an integral structure that is connected. The screw passes through the mounting holes 4 and is connected and fixed to the negative terminal of the battery, or the screw passes through the mounting holes 4 and is fixed by means of a buckle.

[0027] Please see Figure 1An epoxy resin coating layer 5 is provided on the outer side of the connector 6. The epoxy resin coating layer 5 is prepared by first degreasing, degreasing, rust removal / oxidation removal, roughening treatment, and coupling agent activation of the connector 6. Then, epoxy resin is prepared according to the formula. Subsequently, in an environment of 23±2℃ and 40%~60% humidity, a 0.1~0.3mm thick layer of epoxy resin is applied with a scraper (0.2mm gap) or a dispensing machine and assembled within 10 minutes. Then, a pressure of 0.1~0.3MPa is applied and the temperature is increased to 40℃ at 5℃ / min. Pre-curing for 2 hours, then heating to 80℃ for main curing for 4 hours, and finally curing at 120℃ for 1 hour. After curing, cool to room temperature at ≤3℃ / min, and sand the edges with 400-grit sandpaper to remove excess adhesive. This completes the epoxy resin coating layer 5 on the outside of the connector 6. The epoxy resin coating layer 5 can prevent the connector 6 from thermal aging and avoid oxidation of the connector 6 under high temperature for a long time. At the same time, the epoxy resin coating layer 5 can also isolate air, prevent rust and corrosion, and increase the service life of the conductive connector.

[0028] Please see Figure 2 The outer surface of the connector 6 is provided with contact rough holes 7. The contact rough holes 7 are made of 80~120 mesh diamond sandblasting, 0.4~0.6MPa pressure, 15~20cm distance, and 45° angle so that Ra=1.6~3.2μm.

[0029] Please see Figure 2 The connector 6 is provided with a kink 8, which is a two-layer structure that is bent at each other. The two sides are not on the same plane, but are in a parallel state and are bent and connected together.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
